Technical Field
[0001] This utility model relates to the field of dust cover technology for vibrating screens, specifically a dust cover for a high-efficiency vibrating screen. Background Technology
[0002] In the solid waste treatment process, a rotary vibrating screen can be used to screen solid waste. The rotary vibrating screen works by using the reciprocating rotary vibration generated by the excitation of the vibrator. The rotary vibrating screen can screen solid waste according to its size for subsequent processing. The dust cover of the rotary vibrating screen needs to be equipped with an air inlet so that the outside air can enter the dust cover to balance the air pressure.
[0003] However, most of the air inlets on the existing vibrating screen dust covers are located on the surface of the dust cover, with a relatively high air intake height. The air intake direction is opposite to the direction in which the dust generated during screening is sucked out, which reduces the dust discharge efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency dust cover for a vibrating screen to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust cover for a high-efficiency vibrating screen, comprising a cover body, and further comprising,
[0006] An air intake chamber is provided, with a flow guide chamber fixedly connected to its bottom. A dustproof net is fixedly connected to the opening on the upper side of the inner wall of the air intake chamber. A magnetic outer ring and a magnetic inner ring are fixedly connected to the upper sides of the outer wall of the air intake chamber, respectively. Slots are provided on both sides of the top of the cover. The air intake chamber passes through the inner wall of the sliding connection slot. The bottom of the magnetic outer ring and the magnetic inner ring magnetically adheres to the top of the cover.
[0007] The top of the cover is fixedly connected to a feed pipe and an air suction pipe, and the bottom of the cover is fixedly connected to a sealing ring for snapping onto the top of the vibrating screen.
[0008] Preferably, both ends of the top of the cover are connected to a buckle plate by hinges, and both sides of the cover are fixedly connected to a magnetic fixing seat, with one side of the buckle plate magnetically attached to the side of the magnetic fixing seat away from the cover.
[0009] Preferably, the surface of the magnetic fixing base is provided with a threaded hole, and the surface of the buckle plate is threaded with a bolt, the tail end of the bolt being inserted into the inner wall of the threaded hole of the magnetic fixing base.
[0010] Preferably, L-shaped plates are fixedly connected to both sides of the top of the magnetic outer ring.
[0011] Preferably, the top two sides of the cover are provided with openings and glass plates are fixedly connected to the inner walls of the openings.
[0012] Preferably, a sealing cap is slidably fitted onto the top of the feed tube, and a handle is fixedly connected to the top of the sealing cap.
[0013] Preferably, the top of the air intake chamber is magnetically attached to a magnetic cover plate, and the bottom of the magnetic cover plate is attached to the top of the dustproof net.
[0014] Preferably, the inner wall of the flow guide chamber is fixedly connected with an inclined panel.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention utilizes an air intake chamber and a dustproof net. External air is filtered by the dustproof net and then discharged through the opening at the bottom of the air intake chamber. After being guided by the inclined panel, the air is blown downwards onto the screen surface, blowing up the dust and improving the dust removal effect. Then, the dust floats up from the middle and is sucked away by the suction pipe, which reduces the height of the air discharged from the vibrating screen, avoiding affecting the floating of the dust. Moreover, after the air is discharged, it can be blown directly onto the two sides of the screen surface to help the dust float up, further improving the dust removal effect.
[0017] This utility model, by setting up an air inlet chamber, an L-shaped plate, and a glass plate, makes it easy to remove the air inlet chamber from the slot for cleaning without removing the cover. The glass plate is used to observe the internal condition of the vibrating screen, which also does not require removing the cover, making it more convenient and improving maintenance efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model provides a technical solution: a dust cover for a high-efficiency rotary vibrating screen, including a cover body 1, and further including...
[0025] The air intake chamber 2 has a guide chamber 3 fixedly connected to its bottom. A dustproof net 5 is fixedly connected to the opening on the upper side of the inner wall of the air intake chamber 2. A magnetic outer ring 6 and a magnetic inner ring 7 are fixedly connected to the upper sides of the outer wall of the air intake chamber 2 respectively. The top of the cover 1 has slots 8 on both sides. The air intake chamber 2 passes through the inner wall of the sliding connection slots 8. The bottom of the magnetic outer ring 6 and the magnetic inner ring 7 magnetically attach to the top of the cover 1.
[0026] The top of the cover 1 is fixedly connected to the feed pipe 14 and the suction pipe 15, and the bottom of the cover 1 is fixedly connected to the sealing ring 17, which is used to snap onto the top of the vibrating screen.
[0027] Both ends of the top of the cover 1 are connected to the buckle plate 12 by hinges. Both sides of the cover 1 are fixedly connected to the magnetic fixing seat 11. One side of the buckle plate 12 is magnetically attached to the side of the magnetic fixing seat 11 away from the cover 1. The buckle plate 12 is fixed by the magnetic attachment of the magnetic fixing seat 11 and the buckle plate 12. The buckle plate 12 is then connected to the buckle on the outer wall of the vibrating screen equipment. The sealing ring 17 is snapped into the top edge of the vibrating screen to fix the cover 1 completely to the top of the vibrating screen.
[0028] The surface of the magnetic fixing seat 11 is provided with a threaded hole, and the surface of the buckle plate 12 is threaded with a bolt 13. The tail end of the bolt 13 is inserted into the inner wall of the threaded hole of the magnetic fixing seat 11. The bolt 13 further strengthens the stability of the connection between the magnetic fixing seat 11 and the buckle plate 12, and prevents the cover 1 from slipping off from the top of the vibrating screen or from being misaligned, which would lead to a decrease in sealing performance.
[0029] L-shaped plates 9 are fixedly connected to both sides of the top of the magnetic outer ring 6, making it easy to remove the air intake chamber 2 from the slot 8 for cleaning;
[0030] Both sides of the top of the cover 1 are provided with openings and glass plates 16 are fixedly connected to the inner wall of the openings for observing the internal condition of the vibrating screen. This eliminates the need to disassemble the cover 1, making it more convenient.
[0031] A sealing cover 18 is slidably sleeved on the top of the feed pipe 14. A handle 19 is fixedly connected to the top of the sealing cover 18. When not in operation, the sealing cover 18 is placed on the top of the feed pipe 14 to seal the feed pipe 14 and prevent foreign objects from falling into the vibrating screen.
[0032] The top of the air intake chamber 2 is magnetically attached to a magnetic cover plate 10, and the bottom of the magnetic cover plate 10 is attached to the top of the dustproof net 5. When not in operation, the magnetic cover plate 10 is placed on top of the dustproof net 5 to seal the top of the vibrating screen.
[0033] An inclined panel 4 is fixedly connected to the inner wall of the air intake chamber 3. The inclined panel 4 guides the air in the air intake chamber 2, so that the air enters below the cover 1 and is discharged obliquely downwards, blowing towards the screen surface, which is conducive to dust floating.
[0034] Working principle: Cover the top of the vibrating screen with the cover 1, so that the top edge of the vibrating screen is engaged with the sealing ring 17. Then rotate the buckle plate 12 to fasten it onto the buckle on the outer wall of the vibrating screen. The buckle plate 12 is fixed by the magnetic attraction between the magnetic fixing seat 11 and the buckle plate 12 and the bolts 13. Connect the feed pipe 14 to the external discharge device and the suction pipe 15 to the external negative pressure dust collection device. Discharge material into the vibrating screen through the feed pipe 14 to screen and filter the material. The dust generated by screening and filtration floats below the cover 1. The air below the cover 1 is sucked out through the suction pipe 15, thereby removing the dust. The outside air passes through the dustproof net. After filtration, the air is discharged through the opening below the air inlet chamber 2. After being guided by the inclined panel 4, it is blown downwards at an angle onto the screen surface, blowing up the dust and improving the dust removal effect. Then, the dust floats up from the middle and is sucked away by the suction pipe 15. By setting the air inlet chamber 2, the air discharge height in the vibrating screen is reduced, avoiding affecting the dust floating. After the air is discharged, it can be blown directly onto the two sides of the screen surface to help the dust float up, further improving the dust removal effect. This solves the problem that most of the air inlets on the existing vibrating screen dust covers are located on the surface of the dust cover, the air intake height is high, and the air intake direction is opposite to the dust suction direction generated by screening, which reduces the dust discharge efficiency.
