Description

Technical field:

[0001] The utility model relates to the technical field of belt conveyor equipment, in particular to a surface cleaning device for a belt conveyor. Background technology:

[0002] During the polysilicon production process, silicon blocks are usually transported to a water quenching crusher via a belt conveyor for crushing. Since polysilicon is a fragile product, when the silicon material is poured onto the belt, some fine silicon powder or small fragments will adhere to the surface of the belt, causing some silicon material to be wasted and difficult to recycle. Usually, as the belt rotates, it falls to the ground and cannot be collected. In order to ensure that the silicon blocks can be transported stably, multiple push plates are usually fixed on the surface of the belt to perform the pushing operation. Therefore, a scraper cannot be set on the outside of the belt, so that the silicon powder attached to the surface of the belt can only be handled by manual cleaning, which increases the working hours and labor intensity of employees. Utility model content:

[0003] The purpose of the utility model is to provide a surface cleaning device for a belt conveyor to solve the problems raised in the above background technology.

[0004] The utility model is implemented by the following technical solutions:

[0005] A surface cleaning device for a belt conveyor comprises a bracket and a belt rotatably arranged on the bracket, wherein a plurality of push plates are fixed to the belt; a guide hopper is arranged on the surface below the output end of the belt, the bottom of the guide hopper is inserted into a collection box, a collection bucket is provided in the collection box and is located below the discharge end of the guide hopper, a fan is provided at the bottom of the bracket, the air outlet end of the fan is connected to two air guide pipes, the other ends of the two air guide pipes are respectively equipped with air nozzles, the two air nozzles are symmetrically and obliquely inserted on both sides of the top of the guide hopper, so that the two air nozzles can blow toward the surface of the belt.

[0006] Preferably, an opening and closing door is installed on the collection box.

[0007] Preferably, the mouth of the air nozzle is flat.

[0008] Preferably, a vibrator is installed on the outer surface of the guide hopper.

[0009] The advantages of this utility model are: the lower surface of the belt is purged in the form of counter-blowing, so that the silicon powder attached to the belt falls into the guide hopper, and under the vibration of the vibrator, the silicon powder falls into the collection bucket and is collected, which reduces the labor of employees and effectively recovers the silicon powder, reducing the waste of silicon powder.

[0014] In the figure: 1. bracket, 2. belt, 3. push plate, 4. guide hopper, 5. collection box, 5.1. opening and closing door, 6. collection barrel, 7. fan, 8. air guide pipe, 9. air nozzle. Specific implementation method:

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-4 , the utility model provides a technical solution for a surface cleaning device for a belt conveyor:

[0017] A surface cleaning device for a belt conveyor includes a bracket 1 and a belt 2 rotatably mounted on the bracket 1, with a plurality of push plates 3 fixed to the belt 2. A guide hopper 4 is provided on the surface below the output end of the belt 2, and a vibrator 10 is mounted on the outer surface of the guide hopper 4. The bottom of the guide hopper 4 is inserted into a collection box 5, which is equipped with an opening and closing door 5.1. The collection box 5 is provided with a collection bucket 6 located below the discharge end of the guide hopper 4. A fan 7 is provided at the bottom of the bracket 1. The air outlet of the fan 7 is connected to two air guide tubes 8, and the other ends of the two air guide tubes 8 are respectively equipped with air nozzles 9. The mouths of the air nozzles 9 are flat. The two air nozzles 9 are symmetrically and tiltedly inserted on both sides of the top of the guide hopper 4 so that the two air nozzles 9 can blow toward the surface of the belt 2.

[0018] The working principle is as follows: start the fan 7 and the vibrator 10, blow air through the two air nozzles 9 onto the lower surface of the rotating belt 2, and blow the silicon powder adhered to the lower surface of the belt 2 into the guide hopper 4 through counter-blowing. Under the action of the vibrator 10, the silicon powder quickly falls into the collection bucket 6 along the guide hopper 4 for storage. There is no need to manually clean the silicon powder adhered to the surface of the belt 2, which reduces the labor of employees. At the same time, the silicon powder is effectively recovered, reducing the waste of silicon powder.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
