Heavy Scraper Conveyor

 

The conveyor with scraper chain traction and transporting bulk materials in the trough is called scraper conveyor. The middle groove of MS scraper conveyor that can be bent to a limited extent in the horizontal and vertical planes is called flexible scraper conveyor. Among them, the working face conveyor whose body is bent 90 degrees at the intersection of the working face and the transportation roadway is called "corner scraper conveyor". In the current coal mining face, the function of scraper conveyor is not only to transport coal and materials, but also the running track of shearer. Therefore, it has become an indispensable main equipment in modern coal mining technology. The scraper conveyor can maintain continuous operation and the production can be carried out normally.

 

 

 

1. Horizontal, inclined and horizontal + inclined can be conveyed.

2. Multiple feed ports and multiple discharge ports can be set.

3. The material can be cooled while conveying: add a water jacket to the outer layer.

4. The chain and chain plate can be customized according to the material.

5. The conveying distance is long, and the plate chain runs along the track

Note:

1. The chain can be customized: ring chain, plate chain, die forging chain, etc.

2. Types are: single-chain scraper, double-chain scraper, multi-chain scraper, etc.

 

 

 

(1) Transmission system

The transmission system consists of a motor, a reducer and a coupling, which is the power part of the heavy scraper conveyor. The layout of the transmission system has two basic forms, vertical type and horizontal type, and can also be adjusted according to the site location. In order to facilitate installation, a chassis for installing the motor and reducer is designed under the transmission device.

(2) nose frame

The main function of the nose frame is to support the head wheel assembly.

(3) Head wheel assembly

The head wheel assembly is composed of a transmission shaft, a sprocket and a bearing part. The sprocket is connected to the drive shaft by a key, and the power output by the reducer is transmitted to the scraper chain through the drive shaft and the sprocket, so that the scraper chain can perform infinitely closed circular motion.

(4) Scraper chain

The scraper chain is composed of chain, connecting ring and scraper. The scraper is connected and fixed on the chain through the connecting ring, and the material is transported by the pushing or pulling of the scraper.

(5) Middle slot

The middle groove is the main body of the heavy scraper conveyor, and has the function of supporting the material and guiding the scraper chain.

(6) Tailstock

The tailstock mainly supports the tail wheel assembly and the tensioning device.

(7) Tail wheel assembly

The tail wheel assembly is composed of shaft, sprocket and bearing.

(8) Tensioning device

The main function of the tensioning device is to pull the bearing seat of the tail sprocket through the screw rod, so that the tail sprocket moves backward to tension the scraper chain.

(1) After each startup, it should be run without load for a period of time, and the material can be added after the equipment is running normally. The feeding should be kept uniform, and there should be no sudden increase or overload operation.

(2) Unless there are special circumstances, do not stop with a load. Generally, it should be stopped when the material in the standby tank is basically unloaded after the feeding is stopped. If the start-up after emergency stop occurs when the load is full, it must be jogged several times or the material in the tank must be removed in an appropriate amount. This is especially important for MC and MZ types, and the discharge can be carried out by opening the lower observation cover of the bending section.

(3) If several conveyors are combined into one assembly line, one should be started first, and then start one by one, and the stopping sequence should be opposite to the starting sequence. This can also take electrical interlock control.

(4) The operator should always check all parts of the machine, especially the scraper chain and driving device should be in good condition. The middle guide rail is seriously worn, etc.), and it should be repaired or replaced in time.

(5) During operation, iron parts, large hard objects, sundries, etc. should be strictly prevented from being mixed into the conveyor, so as to avoid damage to the equipment or other accidents.

(6) Pay attention to keep all bearings and driving parts well lubricated. For the lubrication of each part of the buried scraper conveyor, see the table below. However, it should be noted that the scraper chain, support rail, head wheel, guide wheel and other components should not be coated with lubricating oil.

(7) Under normal circumstances, the buried scraper conveyor needs to be repaired once a quarter, once in half a year, and once every two years. During overhaul, all parts of the buried scraper conveyor should be removed and cleaned, and the worn parts should be replaced. Motors and reducers are maintained and repaired according to the technical requirements of their respective products.

Q: Bucket elevators are composed of some components

A: Hopper: fixed on the tape (or traction chain), there are three kinds

Deep bucket - suitable for loose materials;

Shallow bucket - materials with high viscosity;

Triangle bucket - heavy and lumpy materials

Shell: Built-in transmission and stopper.

Body: The thin steel plate is welded into a square shell, and the installation is deviated.

Bottom: Install tensioning device.

 

Q: There are several types of bucket elevators

A: 1. According to the layout form: it can be divided into vertical type and inclined type

2. According to different discharge methods: it can be divided into centrifugal, gravity and hybrid.

3. According to different charging methods: it can be divided into excavation type and injection type.

4. According to the structure of the hopper: it can be divided into shallow bucket, deep bucket and triangular bucket.

5. According to different traction components: it can be divided into tape and steel chain.

 

Q: What is the working principle of bucket elevator

A: The conveying working principle of the bucket elevator is as follows: the hopper scoops up the material from the storage below, lifts it to the top with the conveyor belt or chain, turns down after bypassing the top wheel, and the bucket elevator dumps the material into the accepted in the slot. The drive belt of the belt-driven bucket elevator generally adopts a rubber belt, which is installed on the lower or upper driving drum and the upper and lower redirecting drums. The chain-driven bucket elevator is generally equipped with two parallel transmission chains, with a pair of transmission sprockets on the top or bottom, and a pair of redirecting sprockets on the bottom or top. Bucket elevators are generally equipped with casings to prevent dust from flying in the bucket elevators.

 

Q: What are the advantages and disadvantages of bucket elevators?

A: Advantages:

1. The structure is simple, the lateral size is small, and the floor space is small.

2. The lifting height is large, the conveying capacity is good, the body is fully enclosed, and the environmental pollution is small.

3. Low power consumption.

Shortcoming:

1. It is easy to block when overloaded, and the hopper is easy to wear.

2. It is only suitable for conveying powder, granular and small and medium-sized bulk cargo, such as grain, coal, sand, etc.

3. The goods cannot be transported in the horizontal direction.

1. Material bulk density: r=0.2～1.8t/m³

2. Temperature: material temperature t＜100℃

3. Moisture content: For general materials, the materials should not be kneaded into a ball and not easy to loosen; for materials that increase the adhesiveness and compressibility after the moisture content increases, the materials should not be seriously adhered to the scraper.

4. Particle size: The particle size of the material is related to its hardness. If the particle size is too large, it is difficult to transport.

 

 

Due to the different use conditions, use space, and coal seam thickness, the requirements for conveying capacity and laying length are also different. Therefore, there are many types of heavy scraper conveyors produced and used at home and abroad.

 

 

 

1. Please provide material name, specific gravity, particle size, etc

2. Are there other characteristics: such as viscosity, temperature, corrosivity, etc?

3. Conveying length, horizontal conveying or inclined conveying?

4. Conveying capacity / hour
