Description

Technical Field

[0001] The utility model relates to the technical field of metal waste processing, in particular to a dust-proof system for a metal waste conveying device. Background Technique

[0002] Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a multi-alloy composed of more than two elements, it is called special brass. Brass has strong wear resistance and is often used in the manufacture of valves, water pipes, connecting pipes for indoor and outdoor air conditioners, and radiators, etc. In the drawing process of brass rods, the blank copper rods need to be drawn and peeled. A large amount of copper dust will be generated during peeling, and the copper dust is conveyed from the drawing mechanism to the recycling device through a conveyor belt.

[0003] Metal waste is mixed with dust. When the metal waste is poured onto the conveyor belt, the dust will be stirred up and scattered into the environment. When absorbing the dust, a blower is often placed outside the conveyor belt machine to absorb the dust. However, since the position where the metal waste is poured onto the conveyor belt is far from the blower, the dust will still be scattered into the air, resulting in poor dust removal and dust-proof effects. For this reason, we propose a dust-proof system for a metal waste conveying device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust-proof system for a metal waste conveying device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A dust-proof system for a metal waste conveying device, including a conveyor belt frame, a feeding hopper of an external feeding machine, and a dust-proof component. A conveyor belt driven by an external motor is fixedly arranged inside the conveyor belt frame. The feeding hopper is fixedly arranged at the entrance of the conveyor belt and is used for absorbing the dust mixed in the metal waste entering the conveyor belt through the feeding hopper. The dust-proof component includes a dust-proof box, a dust-proof blower, and a dust-proof pipe. The dust-proof box is fixed on the top of the conveyor belt frame. Suction ports are evenly arranged on the outer side of the dust-proof box. The dust-proof pipe is arranged on the outer side of the dust-proof box, and the tail end of the dust-proof pipe is communicated with an external exhaust main pipe. The dust-proof blower is arranged in the middle section of the dust-proof pipe. The utility model blows air towards the outlet of the dust-proof pipe through the dust-proof blower, sucks the gas in the dust-proof box into the dust-proof pipe, thereby forming a negative pressure in the dust-proof box. When the dust in the metal waste poured onto the conveyor belt from the feeding hopper is stirred up, due to the suction of the dust-proof box, it is sucked into the dust-proof box through the suction port, avoiding the dust from spreading into the external environment.

[0006] Preferably, one side of the dust-proof box close to the entrance of the conveyor belt is provided with an inclined surface, the suction ports are arranged in the inclined surface, the dust-proof pipe is fixedly communicated with the bottom of the dust-proof box, the dust-proof blower is fixed in the middle section of the dust-proof pipe, and the air inlet and outlet of the dust-proof blower are fixedly communicated with the dust-proof pipe. The inclined surface faces the feeding hopper, which can absorb the stirred-up dust as timely as possible during the process of pouring the metal waste.

[0007] Preferably, the inside of the air inlet is vertical and perpendicular to the top of the conveyor belt to prevent metal waste from entering the air inlet.

[0008] Preferably, a sealing plate is fixed to the top of the conveyor belt rack, and the dust-proof fan is fixed outside the sealing plate to prevent dust in the external environment from falling onto the conveyor belt during the transportation of metal waste.

[0009] Preferably, a fixing rod is fixed near the conveyor belt inlet at the bottom of the conveyor belt rack, and a plurality of bristles are evenly fixed to the side of the fixing rod near the conveyor belt, which can brush off the dust adhered to the conveyor belt at the bottom of the conveyor belt inlet.

[0010] Preferably, communicating pipes are symmetrically fixed near the conveyor belt inlet on the outside of the conveyor belt rack. One end of the communicating pipe is located at the bottom of the conveyor belt, and the other end is located between the conveyor belt and the inclined plane. Through the communicating pipe, the dust brushed off by the bristles can be sucked onto the conveyor belt by the communicating pipe and then sucked into the dust-proof box through the air inlet.

[0011] Preferably, the communicating pipe is U-shaped, and the inside of the end of the communicating pipe near the inclined plane is an inclined pipe that slopes upward, which can allow the metal waste that accidentally enters the communicating pipe during dumping to fall back onto the conveyor belt.

[0012] Preferably, the bottom inlet of the communicating pipe is located below the fixing rod, which can suck the dust brushed off by the bristles into the communicating pipe in time.

[0013] Preferably, the connection between the dust-proof box and the dust-proof pipe is in an inverted conical shape to facilitate the suction of the dust-proof pipe.

[0014] Compared with the traditional technology, the beneficial effects of the present utility model are as follows:

[0015] 1. By blowing air from the dust-proof fan to the outlet of the dust-proof pipe, the gas in the dust-proof box is sucked into the dust-proof pipe, thereby forming a negative pressure in the dust-proof box. When the dust in the metal waste poured from the feeding hopper onto the conveyor belt is stirred up, due to the suction of the dust-proof box, it is sucked into the dust-proof box through the air inlet, preventing the dust from spreading into the external environment;

[0016] 2. By providing an inclined plane on one side of the dust-proof box close to the feeding hopper and arranging the air inlet on the inclined plane at the same time, the dust raised during the dumping of the metal waste can be absorbed in time. At the same time, since the air inlet is vertically arranged on the inclined plane, it can prevent the metal waste from entering the dust-proof box through the air inlet when it is dumped onto the conveyor belt.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment:

[0024] Please refer to Figures 1 - 4 , in the figure, a dust-proof system of a metal waste conveying device includes a conveyor belt frame 1, a feeding hopper 2 of an external feeding machine, and a dust-proof component 3. A conveyor belt 4 driven by an external motor is fixedly arranged in the conveyor belt frame 1. The feeding hopper 2 is fixedly arranged at the entrance of the conveyor belt 4. The dust-proof component 3 for absorbing the dust mixed in the metal waste entering the conveyor belt 4 through the feeding hopper 2 includes a dust-proof box 5, a dust-proof fan 6, and a dust-proof pipe 7. The dust-proof box 5 is fixed on the top of the conveyor belt frame 1. The connection between the dust-proof box 5 and the dust-proof pipe 7 is in an inverted conical shape to facilitate the suction of the dust-proof pipe 7. Suction ports 8 are evenly arranged on the outer side of the dust-proof box 5. A sealing plate 9 is fixed on the top of the conveyor belt frame 1. The dust-proof pipe 7 is arranged on the outer side of the dust-proof box 5. The tail end of the dust-proof pipe 7 is communicated with an external exhaust main pipe. The dust-proof fan 6 is arranged in the middle section of the dust-proof pipe 7.

[0025] Next, some embodiments of the present application will be described in detail in conjunction with the accompanying drawings:

[0026] Please refer to Figures 1 - 4 , by blowing air from the outlet of the dust-proof fan 6 into the dust-proof pipe 7, the gas in the dust-proof box 5 is sucked into the dust-proof pipe 7, thereby forming a negative pressure in the dust-proof box 5. When the dust in the metal waste poured onto the conveyor belt 4 from the feeding hopper 2 is stirred up, due to the suction of the dust-proof box 5, it is sucked into the dust-proof box 5 through the suction port 8, avoiding the spread of dust to the external environment.

[0027] Among them, one side of the dust-proof box 5 close to the entrance of the conveyor belt 4 is provided with an inclined surface 10. The air suction port 8 is arranged inside the inclined surface 10. The dust-proof pipe 7 is fixedly communicated with the bottom of the dust-proof box 5. The dust-proof fan 6 is fixed in the middle section of the dust-proof pipe 7. The air inlet and outlet of the dust-proof fan 6 are both fixedly communicated with the dust-proof pipe 7. The inclined surface 10 faces the feeding hopper 2, so that the dust stirred up during the dumping of metal waste can be absorbed as timely as possible. A sealing plate 9 is fixed on the top of the conveyor belt frame 1, and the dust-proof fan 6 is fixed outside the sealing plate 9 to prevent the dust in the external environment from falling onto the conveyor belt 4 during the transportation of metal waste.

[0028] It should be noted that, as Figure 4 shown, the inside of the air suction port 8 is vertical and perpendicular to the top of the conveyor belt 4, preventing metal waste from entering the air suction port 8.

[0029] When the feeding hopper 2 dumps metal waste onto the conveyor belt 4, the dust-proof fan 6 blows air towards the outlet of the dust-proof pipe 7, thereby sucking the gas in the dust-proof box 5 into the dust-proof pipe 7, forming a negative pressure in the dust-proof box 5. At this time, when the dust in the metal waste dumped by the feeding hopper 2 onto the conveyor belt 4 is stirred up, due to the suction of the dust-proof box 5, it is sucked into the dust-proof box 5 through the air suction port 8. By arranging the inclined surface 10 on one side of the dust-proof box 5 close to the feeding hopper 2 and setting the air suction port 8 on the inclined surface 10 at the same time, the raised dust can be timely absorbed during the dumping of metal waste, improving the dust-proof effect of the device. At the same time, since the air suction port 8 is vertically arranged on the inclined surface 10, it can prevent the metal waste from entering the dust-proof box 5 through the air suction port 8 when it is dumped onto the conveyor belt 4.

[0030] As Figure 1 shown, in this embodiment, a fixed rod 11 is fixed at the bottom of the conveyor belt frame 1 close to the entrance of the conveyor belt 4. A plurality of brush hairs 12 are uniformly fixed on one side of the top of the fixed rod 11 close to the conveyor belt 4, which can brush off the dust adhered to the conveyor belt 4 at the bottom of the entrance of the conveyor belt 4. Two communicating pipes 13 are symmetrically fixed on the outside of the conveyor belt frame 1 close to the entrance of the conveyor belt 4. One end of each communicating pipe 13 is located at the bottom of the conveyor belt 4, and the other end is located between the conveyor belt 4 and the inclined surface 10. Through the communicating pipes 13, the dust brushed off by the brush hairs 12 can be sucked onto the conveyor belt 4 by the communicating pipes 13 and then sucked into the dust-proof box 5 through the air suction port 8.

[0031] Furthermore, as Figure 3 shown, the communicating pipe 13 is U-shaped. The inner part of the end of the communicating pipe 13 close to the inclined surface 10 is an inclined pipe that slopes upward, which can allow the metal waste accidentally entering the communicating pipe 13 during dumping to fall back onto the conveyor belt 4. The bottom inlet of the communicating pipe 13 is located below the fixed rod 11, which can timely suck the dust brushed off by the brush hairs 12 into the communicating pipe 13.

[0032] When the conveyor belt 4 moves, relative movement occurs between the bottom at the entrance of the conveyor belt 4 and the bristles 12. The bristles 12 brush off the dust attached to the conveyor belt 4. Due to the suction force of the suction port 8, the dust brushed off by the bristles 12 can be sucked from the connecting pipe 13 onto the conveyor belt 4 through the connecting pipe 13 and then sucked into the dust-proof box 5, thereby further reducing the dust content on the conveyor belt 4 and improving the dust-proof effect.
