This design makes it difficult to collect the intercepted dust, and the dust on the filters affects the filtration effect of the filters. In view of this, we propose a dust collection device for waste battery recycling. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] This embodiment provides a technical solution:

[0035] Please see Figures 1-6As shown, a dust collection device for recycling waste batteries includes a straight cylinder 1, a conical cylinder 2 at the bottom of the straight cylinder 1, and a detachable collection cylinder 3 at the bottom of the conical cylinder 2. A dust inlet 10 is installed on the rear side of the outer wall of the straight cylinder 1, and a suction pipe 4 is installed at the dust inlet 10. A detachable cylinder cover 5 is provided at the top of the straight cylinder 1, and the cylinder cover 5 is fixedly connected to the straight cylinder 1 by bolts. An exhaust pipe 50 is rotatably installed at the center of the cylinder cover 5, and a first gear 51 is coaxially keyed to the exhaust pipe 50. A second gear 52 meshes with one side of the first gear 51. A motor 53 for driving the second gear 52 is provided above the cylinder cover 5. Below the cylinder cover 5, inside the straight cylinder 1, are two parallel fixing plates 54. A dust filter 55 is fixed between the two fixing plates 54, and the dust filter 55 communicates with the fixing plates 54. The exhaust pipe 50 is fixedly connected by bolts; the bottom end of the exhaust pipe 50 passes through the cylinder cover 5 and is fixed to the upper fixing plate 54, and the exhaust pipe 50 is connected to the inside of the dust filter 55; the inside of the straight cylinder 1 is provided with dust removal components 6 on both sides of the dust filter 55. The dust removal components 6 include a fixing seat 60 fixedly connected to the inner wall of the straight cylinder 1. The fixing seat 60 is fixedly connected to the straight cylinder 1 by bolts. A detachable mounting plate 65 is provided on one side of the fixing seat 60. A cleaning brush 650 is provided on the side wall of the mounting plate 65 near the dust filter 55. The cleaning brush 650 is tightly bonded to the mounting plate 65, and the end of the cleaning brush 650 is in contact with the outer wall of the dust filter 55.

[0036] Furthermore, a limiting groove 600 is formed on the side wall of the fixed base 60 near the mounting plate 65, and a connecting groove 602 is formed on the top of the fixed base 60. A sliding groove 601 is formed on the inner wall of the limiting groove 600 near the top. A slider 61 is slidably installed in the sliding groove 601. A connecting block 62 that is slidably connected to the connecting groove 602 is fixed on the top of the slider 61. A guide rod 63 is fixed in the connecting groove 602. The guide rod 63 passes through the connecting block 62 and is slidably connected to the connecting block 62. A spring 64 for pressing against the connecting block 62 is sleeved on the outside of the guide rod 63. A support block 603 is also fixed at the bottom end of the side wall of the fixed base 60 near the mounting plate 65. The mounting plate 65 presses against the support block 603. A limiting block 66 is fixed on the side wall of the mounting plate 65 near the fixed base 60. The limiting block 66 is inserted into the limiting groove 600. The end of the slider 61 presses against the top of the limiting block 66. This design facilitates the assembly and disassembly of the mounting plate 65 and the fixing base 60. The assembly and disassembly of the mounting plate 65 makes it easy to clean or replace the cleaning brush 650 later, so as to ensure the cleaning effect of the cleaning brush 650.

[0037] In this embodiment, the straight cylinder 1 and the conical cylinder 2 are integrally formed structures, and both the straight cylinder 1 and the conical cylinder 2 are made of stainless steel. The integrally formed straight cylinder 1 and conical cylinder 2 have better connection strength, ensuring the reliable connection between the straight cylinder 1 and the conical cylinder 2, while the stainless steel material has the advantages of corrosion resistance and high strength, ensuring the service life of the straight cylinder 1 and the conical cylinder 2.

[0038] In this embodiment, a mounting bracket 59 is fixedly connected to the top of the cylinder cover 5 by bolts. The exhaust pipe 50 passes through the mounting bracket 59 and is rotatably connected to it. The first gear 51 and the second gear 52 are both located inside the opening of the mounting bracket 59. The mounting bracket 59 protects the first gear 51 and the second gear 52, preventing foreign objects from obstructing their rotation.

[0039] In this embodiment, two symmetrical connecting plates 57 are fixed at the bottom edge of the cylinder cover 5. The connecting plates 57 are threaded with fixing bolts 58, the ends of which pass through the straight cylinder 1. This design facilitates the disassembly and assembly of the cylinder cover 5, thereby simplifying the cleaning and maintenance of the inside of the straight cylinder 1 later.

[0040] In this embodiment, multiple support rods 56 are bolted between the two fixing plates 54, and the support rods 56 are distributed in a ring with equal spacing. The arrangement of the support rods 56 increases the reliability and stability of the connection between the two fixing plates 54, thereby ensuring the reliable installation of the dust filter screen 55.

[0041] In this embodiment, a threaded ring 20 is coaxially fixed to the bottom end of the cone 2, and the top opening of the collecting cylinder 3 is threadedly connected to the threaded ring 20. The threaded connection facilitates the disassembly and assembly of the collecting cylinder 3, thereby facilitating the cleaning and recycling of dust inside the collecting cylinder 3.

[0042] It is understood that the cross-sectional shape of both the limiting block 66 and the limiting groove 600 in this embodiment is trapezoidal, so that after the limiting block 66 is inserted into the limiting groove 600, the mounting plate 65 will not detach from or fall off the fixing seat 60.

[0043] It should be added that the cone 2 in this embodiment has an overall shape that is wider at the top and narrower at the bottom. This design allows the dust to move downwards after falling into the cone 2, which is conducive to the dust gathering into the collection cylinder 3.

[0044] It is worth noting that the conventional technology of the motor 53 involved in this embodiment is not described in detail here.

[0045] In practical use, the user first connects the power supply to the motor 53. The motor 53 starts to work, and the output shaft of the motor 53 rotates, driving the second gear 52 to rotate. Since the second gear 52 meshes with the first gear 51, the first gear 51 rotates and drives the exhaust pipe 50 and the fixing plate 54 to rotate. The fixing plate 54 then drives the support rod 56 and the dust filter 55 to rotate. At the same time, the dust gas enters the straight cylinder 1 through the suction pipe 4 and the dust inlet 10. When the dust gas passes through the dust filter 55, the dust is intercepted on the outside of the dust filter 55, and some of the dust falls downward and falls into the collection cylinder 3 through the cone 2. At the same time, as the dust filter 55 rotates, the cleaning brush 650 continuously cleans the outer wall of the dust filter 55. The dust adhering to the outside of the dust filter 55 falls downward and falls into the collection cylinder 3 through the cone 2.

[0046] When it is necessary to remove the mounting plate 65, the user first pushes the connecting block 62 to one side. The connecting block 62 slides along the guide rod 63 and compresses the spring 64. At the same time, the connecting block 62 drives the slider 61 to slide along the slide groove 601. When the slider 61 disengages from above the limiting block 66, the user lifts the mounting plate 65 upwards. The mounting plate 65 then drives the limiting block 66 to disengage from the limiting groove 600, and the mounting plate 65 is thus disassembled.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
