Product introduction

The embedded scraper conveyor is a kind of conveyor. From the appearance, it is a fully enclosed rectangular shell. The scraper chain is all buried in the material, only the inlet and outlet are not fully closed. It uses the moving scraper chain to transport materials according to the predetermined target. It is widely used in metallurgy, mining, thermal power plant and other industries.

Requirements for materials
 
1. The temperature of material transported by general machine is less than 100 ° C; the temperature of hot material conveying material is 100 ~ 450 ° C, and the instantaneous material temperature is allowed to reach 800 ° C.
2. The bulk density of material is p = 0.2 ~ 2.5t/m3, and the bulk density of material is r = 0.2 ~ 1.8t/m3
3. When conveying materials, there are also high requirements for material size, viscosity and moisture content. If the moisture content is too high, the viscosity and caking property will be increased, and the material will adhere to the scraper seriously. Therefore, it should be generally held that the material can still be loose after being kneaded and released.
4. The particle size of the material is related to its hardness. If the particle size is too large, it is not easy to transport.

Product features

1. Because the shell is closed and has strong sealing performance, it can effectively improve working conditions and reduce environmental pollution when conveying materials.
2. The structure is simple and reasonable. It is mainly composed of closed shell, scraper chain, driving device and tensioning device.
3. Compared with other conveying equipment, it is small in volume, easy to operate and convenient in installation and maintenance.
4. The design is very reasonable. It can be multi-point feeding and multi-point unloading.
5. Under the rotation of the reducer, the machine runs very smoothly, with low noise and strong flexibility in process modeling and layout.
6. There are many types of scraper conveyor, such as general type, hot material type, soda ash special type (ordinary type, high efficiency type), grain special type, cement special type, power plant special type and so on.

working principle

      In the process of conveying materials, whether it is horizontal or inclined transportation, if the internal friction force and side pressure of the material itself, the forward direction pressure of the moving scraper chain and the pushing force of the lower material on the upper material are used, the combination of these forces can effectively overcome the weight of the material itself and the external force between the material and the shell when the material is transported in the intermediate tank The friction force makes the material move forward continuously.

Chain features
 
The chain of embedded scraper conveyor is made of high quality alloy steel, precision forged by friction press and heat treated by continuous mesh belt furnace, which has the advantages of high temperature resistance and high tensile strength. 304 stainless steel chain can be used for conveying corrosive materials, including welding parts of chain.
Although the material thickness and size standard of stainless steel chain is the same as that of ordinary embedded scraper conveyor chain, the price difference is very big, so this kind of chain will not be selected for materials with strong corrosivity. Once the stainless steel chain is used, the shell of buried scraper conveyor must be made of this stainless steel.
Each manufacturer of stainless steel chain is supplied at the price of per meter according to the specifications used. As a result, the overall price of such stainless steel material is several times higher than that of ordinary embedded scraper conveyor,
Therefore, users can choose the appropriate material and specification according to the different materials to be transported.

Product classification

Buried scraper conveyor is widely used in chemical industry, machinery, metallurgy, light industry, grain, medicine, transportation, hydropower and other departments. There are many models, including general-purpose type, hot material type, soda ash special-purpose type (ordinary type, high-efficiency type), grain special-purpose type, cement special-purpose type, power plant special-purpose type, etc.
The general embedded scraper conveyor is divided into three types: Ms type (horizontal type), MC type (vertical type), MZ type (Z type).
MS type horizontal buried scraper conveyor can be divided into ordinary type and large inclined type. The installation angle of common type is 0 ° ≤ α≤ 15 ° and that of large inclined type is 15 ° < α < 30 °
The bulk density r of materials transported by MZ type buried scraper conveyor is generally less than 1.0.

Operation and maintenance

1. Regularly check the oil level of the hydraulic coupling to reduce the dynamic load and impact load of the chain. When conveying overload, it can play a protective role and effectively extend the service life of the chain.
2. Before the operation of the machine, all bolts, pin shafts and pins must be tightened in place, so as to achieve the required torque.
3. Timely check and adjust the operation time of the scraper according to the regulation.
4. When conveying materials, the operator should make continuous inspection to check the missing condition of cleaning plate and scraper pin shaft. If there is bending chain plate, take remedial measures in time.
5. Check the head part of the scraper conveyor regularly to see if its guide frame is deformed or falling off. If any, report to the maintenance personnel in time.
6. Each time when changing the chain, it is necessary to ensure that each chain moves freely and has strong flexibility.
