Description

Technical Field

[0001] The present application relates to the technical field of raw material transportation, and in particular to a cement raw material conveying device. Background Art

[0002] The material which is mixed in proportion and ground to a certain fineness by lime raw materials, clay raw materials and a small amount of correction raw materials (sometimes mineralizers, crystal seeds, etc. are also added, and coal is also added in vertical kiln production) is called cement raw material.

[0003] The prior art CN212173498U discloses a cement raw material transportation device, which puts the cement raw material into a hopper. When the cement raw material falls onto the conveyor belt through the hopper, the raised dust is blocked by the outer shell and will not pollute the environment. The cement raw material is then transported to the conveying port through the conveyor belt. When the cement raw material is transported, the conveyor belt will be stained with cement raw material, and due to gravity, a small amount of cement raw material falls to the bottom of the conveyor belt. The cement raw material at the bottom of the conveyor belt can be sent to the top of the conveyor belt again through the cooperation of the dust suction plate, the dust suction port, the dust suction pipe and the dust collector.

[0004] When the above-mentioned prior art is in use, due to the large height difference between the feed hopper and the conveyor belt, the raw material is easily splashed when it falls on the conveyor belt, and a large amount of dust is generated, which is very likely to cause environmental pollution. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a cement raw material conveying device to reduce splashing of cement raw material when it falls and reduce the generation of dust.

[0006] The embodiment of the present application provides a cement raw material conveying device, which adopts the following technical solutions:

[0008] Preferably, a dust extraction mechanism is provided on the cover body, and the dust extraction mechanism includes an exhaust fan and a dust hopper. The exhaust fan is arranged outside the cover body, and both ends of the dust hopper are respectively connected to the baffle. The upper end of the dust hopper passes through the cover body, and the dust hopper is connected to the exhaust fan.

[0009] Preferably, a filter is provided inside the dust collecting hopper.

[0010] Preferably, the conveying mechanism includes a frame and a conveyor belt, one end of the guide groove is connected to the frame, the other end of the guide groove is connected to the cover body, and a cleaning mechanism is provided on the guide groove, and the cleaning mechanism is used to clean the conveyor belt.

[0011] Preferably, the cleaning mechanism comprises a motor and a cleaning brush, and both the motor and the cleaning brush are arranged on the guide groove, the motor drives the cleaning brush to rotate, and the cleaning brush abuts against the conveyor belt.

[0012] Preferably, a reinforcing plate is provided at one end of the baffle away from the dust collecting hopper, and the reinforcing plate is connected to the inner wall of the cover body.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] The present application sets a feeding mechanism, and after the cement raw material is fed into the hopper, the cement raw material first enters the vertical pipe, and then enters the feeding end of the conveying mechanism through the arc pipe. This process can reduce the impact of the cement raw material on the conveying mechanism, reduce the splashing of the cement raw material when it falls, and reduce the generation of dust. The two baffles block the cement raw material to further reduce the splashing of the cement raw material and guide the flow of the cement raw material.

The cover body 2 and the conveying mechanism 3 are both arranged on the base 1, the conveying mechanism 3 is located inside the cover body 2, and the feeding mechanism 4 includes a hopper 5 and a guide pipe 6. The hopper 5 is arranged on the cover body 2, and the guide pipe 6 includes a vertical pipe 7, an arc pipe 8 and two symmetrically arranged baffles 9, the arc pipe 8 is arranged between the vertical pipe 7 and the baffle 9, the vertical pipe 7 is connected to the hopper 5, and one end of the arc pipe 8 close to the baffle 9 is located above the feeding end of the conveying mechanism 3, and a guide groove 10 is arranged below the discharging end of the conveying mechanism 3, and the guide groove 10 passes through the cover body 2.

[0030] When in use, after the cement raw material is fed into the hopper 5, the cement raw material first enters the vertical pipe 7, and then enters the feeding end of the conveying mechanism 3 through the arc pipe 8. This process can reduce the impact of the cement raw material on the conveying mechanism 3, reduce the splashing of the cement raw material when it falls, and reduce the generation of dust. The two baffles 9 block the cement raw material to further reduce the splashing of the cement raw material and guide the flow of the cement raw material. The cover body 2 isolates the conveying mechanism 3 from the external environment to avoid the overflow of dust during the conveying of the cement raw material. After the conveying mechanism 3 conveys the cement raw material to the discharge end, the cement raw material falls on the guide groove 10 and is discharged through the guide groove 10.

[0031] In this embodiment, a dust extraction mechanism 11 is provided on the cover body 2, and the dust extraction mechanism 11 includes an exhaust fan 12 and a dust hopper 13. The exhaust fan 12 is arranged outside the cover body 2, and the two ends of the dust hopper 13 are respectively connected to the baffle 9. The upper end of the dust hopper 13 passes through the cover body 2, and the dust hopper 13 is connected to the exhaust fan 12. Under the action of the exhaust fan 12, a negative pressure is generated inside the dust hopper 13, which is convenient for adsorbing dust generated during the falling process of cement raw materials.

When the conveyor belt 16 conveys the cement raw material, the motor 18 drives the cleaning brush 19 to rotate, and the cleaning brush 19 cleans the cement raw material remaining on the conveyor belt 16, and the cement raw material cleaned by the cleaning brush 19 falls on the guide groove 10.

[0035] In this embodiment, a reinforcing plate 20 is provided at one end of the baffle 9 away from the dust collecting hopper 13 . The reinforcing plate 20 is connected to the inner wall of the cover body 2 . The reinforcing plate 20 is used to improve the overall stability of the material guide tube 6 .
