Description of the Drawings
[0011] Appendix Figure 1 It is a schematic diagram of the overall structure of the crusher device of the present utility model. Specific Embodiments
[0012] The following further describes the present utility model with reference to the drawings.
[0013] As shown in the appendix Figure 1 The described dust-free feeding crusher device includes a feeding hopper 2, a crushing main machine 15, and a negative pressure dust suction device. The feeding hopper 2 is connected to the crushing main machine 15 through a feeding mechanism 14. After the material is put into the feeding hopper 2, the material in the feeding hopper 2 can be sent into the crushing main machine 15 through the feeding mechanism 14, and then the crushing main machine 15 crushes the material. In one embodiment, the feeding mechanism 14 is a screw conveyor. When the screw conveyor starts, it can send the material in the feeding hopper 2 into the crushing main machine 15 for crushing.
[0014] The crushing main machine 15 is connected to the negative pressure dust suction device, so that negative pressure can be generated in the crushing main machine 15. A dust collection pipe 6 is also provided between the crushing main machine 15 and the feeding hopper 2, and both ends of the dust collection pipe 6 are respectively communicated with the crushing main machine 15 and the feeding hopper 2. During the process of putting the material into the feeding hopper 2, the negative pressure dust suction device generates negative pressure in the crushing main machine 15. Since the inside of the crushing main machine 15 is a negative pressure environment, the crushing main machine 15 can suck away the dust generated in the feeding hopper 2 through the dust collection pipe 6, thereby preventing the dust generated during the feeding process from escaping outside the feeding hopper 2 and keeping the air in the workshop clean.
[0015] The crushing main unit 15 is an ultrafine crusher. The discharge pipe 7 of the crushing main unit 15 is connected to a cyclone separator 8, and the negative pressure dust suction device is also connected to the cyclone separator 8. When the crushing main unit 15 crushes the material to a specific fineness, the negative pressure applied by the negative pressure dust suction device inside the crushing main unit 15 can suck the dust and the crushed material into the cyclone separator 8, and then the cyclone separator 8 separates the dust and the crushed material, while the negative pressure dust suction device will suck away the dust separated in the cyclone separator 8.
[0016] A rotary air lock and a discharge port are provided at the lower end of the cyclone separator 8. The material separated by the cyclone separator 8 continuously discharges from the discharge port under the action of the rotary air lock. A dust recovery pipe 16 is provided at the discharge port. One end of the dust recovery pipe 16 is adjacent to the discharge port, and the other end of the dust recovery pipe 16 is communicated with the dust collection pipe 6. The crushing main unit 15 can suck away the dust generated at the discharge port through the dust collection pipe 6 and the dust recovery pipe 16. As shown in an Figure 1 embodiment shown in the appendix, a dust collection hood 19 is installed at the discharge port. The dust recovery pipe 16 includes two branch pipes 17. The suction inlets of the two branch pipes 17 are installed on the dust collection hood 19. When the material is discharged from the discharge port, the generated dust enters the dust recovery pipe 16 from the suction inlets of the branch pipes 17, and then enters the crushing main unit 15 through the dust collection pipe 6 to realize the recovery of dust.
[0017] The negative pressure dust suction device includes a dust removal box 10 and a draft fan 13. The draft fan 13 is connected to the dust removal box 10 through a suction pipe 11, and the dust removal box 10 is connected to the cyclone separator 8 through a dust suction pipe 9. A fan silencer 12 is provided on the draft fan 13 to reduce the noise generated by the draft fan 13. A dust adsorption assembly is provided inside the dust removal box 10. In one embodiment, the dust adsorption assembly is a dust suction cloth bag. A door that can be opened and closed is also provided on the dust removal box 10. After opening the door, the dust removal cloth bag inside the dust removal box 10 can be removed and cleaned. A discharge port is provided at the lower end of the dust removal box 10. A control valve 20 and a dust collection bucket 21 are provided at the discharge port. The control valve 20 is a pneumatic butterfly valve. When the control valve 20 is opened, the dust accumulated in the dust removal box 10 will fall into the dust collection bucket 21 from the discharge port.
[0018] A feeding hood 5 is provided at the feeding port of the feeding hopper 2, and a door cover 4 that can be opened and closed is provided on the feeding hood 5. Refer to the appendix Figure 1 shown. The door cover 4 is a flip cover. After the door cover 4 is turned up and opened, it can be fixed and supported by a gas spring 3 to keep the door cover 4 in an open state. A feeding platform 1 is provided on the feeding hopper 2. During the feeding process, the material can be moved onto the feeding platform 1 and then poured into the feeding hopper 2. One end of the dust collection pipe 6 is correspondingly connected to the feeding hood 5, and the pipe orifice at this end of the dust collection pipe 6 faces the feeding port, so that the dust suction effect of the dust collection pipe 6 is better.
[0019] A main crusher 15 is provided with a main muffler 18. Around the main muffler 18 is a layer of thick sound-absorbing cotton, and it is hollow in the middle to facilitate air intake and ventilation while reducing noise.
[0020] The working mode of the present utility model is as follows: When starting up and running, the induced draft fan 13 is started to create a negative pressure environment in the dust removal box 10 and the main crusher 15. Flip up the door cover 4 of the feeding port, and support the door cover 4 through the gas spring 3 to keep it in an open state. Move the material onto the feeding platform 1 and then pour it into the feeding hopper 2. During the process of pouring the material, the generated dust will be sucked into the main crusher 15 through the dust collection pipeline 6 under the action of negative pressure. After the feeding is completed, the screw conveyor sends the material in the feeding hopper 2 into the main crusher 15 for crushing. When the material is crushed to the specific fineness requirement, the material will enter the cyclone separator 8 through the discharge pipeline 7. The cyclone separator 8 separates the material and the dust. The separated dust is sucked into the dust removal box 10, and the separated material is discharged from the discharge port. Due to the existence of the dust recovery pipeline 16, the dust generated at the discharge port will be sucked back into the main crusher 15 through the dust recovery pipeline 16 and the dust collection pipeline 6. In summary, the present utility model can not only achieve dust-free feeding, but also realize dust recovery during discharging, and there will be no dust escaping during the production process, which can keep the air in the workshop clean.
[0021] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
