Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, and in particular relates to a negative pressure dust removal system for assembly workshops. Background Technology

[0002] In battery production and assembly workshops, as well as waste battery recycling workshops, the assembly and disassembly of products often generate a large amount of dust, fine debris, and other pollutants. These pollutants deteriorate the working environment and endanger the health of employees. Therefore, the existing dust removal methods in workshops mainly rely on centralized dust collection systems. This involves installing dust collection hoods at dust-generating workstations and controlling the dust collection hoods to connect to negative pressure equipment through air passages. The negative pressure equipment generates negative pressure around the opening end of the dust collection hood to remove dust. Although existing centralized dust collection systems have high power, cleaning their filter components often requires stopping the machine and disassembling them, which is cumbersome and affects the continuity of production.

Through the synergistic effect of the partition, guide rod A, movable ring A, striking ring and telescopic module, the system achieves periodic automatic dust removal of the filter components, thus solving the problems raised in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a negative pressure dust removal system for an assembly workshop, comprising a tubular shell with a top cover connected to its top; a filter assembly is detachably installed at the bottom of the top cover / top of the shell; a partition is provided inside the top cover, and a guide rod A is passed through the partition; a movable ring A and a striking ring are connected to the top and bottom of the guide rod A; a telescopic module is connected between the upper surface of the partition and the movable ring A; the partition and the top cover are respectively provided with concentric threaded holes and openings A, and a sealing ring is provided on the inner wall of the opening A; it also includes a bottom threaded connection to a screw... The exhaust pipe at the perforated area is sealed with a sealing ring; a dust collection box is detachably installed at the bottom of the housing; an air inlet pipe is provided through one side of the housing, forming a sealed cavity through the housing and top cover. Negative pressure is generated by an external fan, and dust-laden gas enters from the air inlet pipe, is filtered by the filter assembly, and then discharged through the exhaust pipe after the dust is removed; the automatic dust removal function is achieved by a partition, guide rod A, movable ring A, knocking ring, and telescopic module, which shakes off the dust adhering to the filter assembly through periodic actions, and the collected dust finally falls into the dust collection box at the bottom.

[0005] Furthermore, the air inlet pipe has one end facing downwards inside the housing. The dust-laden airflow is ejected from the downward-facing air inlet pipe and directly impacts the bottom space of the dust collection box. Larger particles fall directly to the bottom of the box due to inertia, while finer particles rise with the airflow and enter the filtration area. Utilizing the principle of gravity pre-settling, some of the heavier dust particles can initially settle after entering the housing due to the downward-facing design, reducing the load on the upstream filtration components and extending their service life.

[0006] Furthermore, the inner wall of the housing is provided with a guide tube that gradually narrows from top to bottom; it also includes a movable ring B that is sealed to the open end of the guide tube, and a conical guide cover is connected to the top side of the movable ring B; a connecting frame is connected to the bottom side of the movable ring B, and a control rod is connected to the connecting frame, the control rod penetrating through the dust collection box; a sealing layer is provided on the outer wall of the movable ring B; the guide tube and the conical guide cover work together to smoothly guide the dust filtered by the filter assembly into the dust collection box; the control rod can be used to operate the opening and closing of the movable ring B and the guide tube, realizing the sealing of the dust channel when disassembling the collection box, effectively preventing secondary pollution caused by dust leakage from the interface during the cleaning process.

[0007] Furthermore, the bottom end of the control rod is connected to a columnar handle, and the outer side of the dust collection box is provided with a guide sleeve A that cooperates with the columnar handle; the control rod includes a first rod body connected to the connecting frame, and a second rod body connected to the top of the columnar handle and penetrating the dust collection box, with mutually cooperating insertion rods and insertion holes at opposite ends of the first rod body and the second rod body; a pin hole A is provided on the side wall of the guide sleeve A, and a pin hole B is provided at the bottom end of the second rod body; it also includes a pin rod inserted into the pin holes A and B, and by inserting the pin rod into the pin holes A and B, the control rod can be firmly locked in the closed or open position of the guide tube, preventing the movable ring B from moving accidentally during operation.

[0009] Furthermore, a guide rod B is connected to the connecting frame located around the control rod, and a guide sleeve B that cooperates with the guide rod B is provided on the inner bottom side of the dust collection box. The cooperation between the guide rod B and the guide sleeve B provides additional guidance and support for the movement of the control rod and the connecting frame, preventing them from swaying or jamming during movement, and ensuring the accuracy and reliability of the sealing action between the movable ring B and the guide tube.

[0010] Furthermore, the outer wall at the bottom end of the housing is provided with a first threaded structure, and the inner wall at the opening end of the dust collection box is provided with a second threaded structure that is threadedly connected to the first threaded structure.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Please see Figure 1-2 As shown, this utility model is a negative pressure dust removal system for an assembly workshop, including a tubular shell 1. The top of the shell 1 is connected to a top cover 3. A filter assembly is detachably installed at the bottom of the top cover 3. An exhaust pipe 36 is provided on the top cover 3. A dust collection box 4 is detachably installed at the bottom of the shell 1. An air inlet pipe 10 is provided through one side of the shell 1. In use, the air inlet end of the air inlet pipe 10 is connected to at least one air collection hood installed at the dust-generating workstation through a pipeline system. The exhaust pipe 36 is connected to a negative pressure device through a pipeline. That is, in use, the negative pressure device forms a negative pressure at the port of the air collection hood. At this time, the dust generated at the workstation is introduced into the shell 1 through the air collection hood, the pipeline system and the air inlet pipe 10 in sequence. After passing through the filter assembly 2, the dust is intercepted, and clean air is discharged through the exhaust pipe 36. When enough dust is collected, the dust collection box 4 can be removed for cleaning.

[0019] Specifically, the top cover 3 provided in this application is provided with two independent cavities that divide the top cover 3 into upper and lower sections. A guide rod A32 is provided through the partition 31. The top and bottom ends of the guide rod A32 are connected to a movable ring A37 and a striking ring 33. A telescopic module 38 is connected between the upper surface of the partition 31 and the movable ring A37. In use, the telescopic module 38 is activated to drive the movable ring A37 and the striking ring 33 to move up and down along the guide rod A32. The striking ring 33 is used to strike the filter assembly, causing the dust to fall into the dust collection box 4.

[0020] Furthermore, the partition plate 31 and the top cover 3 are respectively provided with a threaded hole 311 and an opening A34 in a concentric structure, and a sealing ring 35 is provided on the inner wall of the opening A34; it also includes an exhaust pipe 36 with its bottom threaded connection to the threaded hole 311, and the exhaust pipe 36 and the sealing ring 35 are sealed together.

[0021] Based on the above configuration, in order to reduce the load on the upstream filter assembly 2 and extend its service life, the air inlet pipe 10 in this application has one end with its opening facing downwards inside the housing 1. By utilizing the principle of gravity pre-settling, some heavier dust particles can be preliminarily settled directly after entering the housing due to the downward-facing design, thus reducing the load on the upstream filter assembly 2.

[0022] It is understood that, in one feasible embodiment, a guide tube 11 that gradually narrows from top to bottom is provided on the inner wall of the housing 1; it also includes a movable ring B12 that is sealed to the open end of the guide tube 11, the outer wall of the movable ring B12 is provided with a sealing layer, and a conical guide cover 13 is connected to the top side of the movable ring B12; a connecting frame 14 is connected to the bottom side of the movable ring B12, and a control rod 41 is connected to the connecting frame 14. The control rod 41 passes through the dust collection box 4, and the conical guide tube is used during operation. The cover 13 can smoothly guide the shaken dust into the guide pipe 11, and through the action of the guide pipe 11, into the dust collection box 4, preventing dust accumulation at the interface. During normal operation, the movable ring B12 is disengaged from the guide pipe 11 under the action of the control rod 41. When it is necessary to clean the dust collection box 4, lift the control rod 41 upward, which will move the movable ring B12 and the conical guide cover 13 upward. At this time, the movable ring B12 is sealed and fitted with the guide pipe 11, and the dust collection box 4 can be safely unscrewed for cleaning.

[0023] To facilitate the up-and-down movement of the control lever 41 and to limit the position of the control lever 41 after its up-and-down movement, such as Figure 3 A columnar handle 42 is connected to the bottom end of the control rod 41. A guide sleeve A44 that mates with the columnar handle 42 is provided on the outer side of the dust collection box 4. The control rod 41 includes a first rod body connected to the connecting frame 14 and a second rod body connected to the top of the columnar handle 42 and penetrating through the dust collection box 4. The opposite ends of the first rod body and the second rod body are provided with mutually cooperating insertion rods and insertion holes. A pin hole A441 is provided on the side wall of the guide sleeve A44, and a pin hole B411 is provided at the bottom end of the second rod body. It also includes a pin rod 47 that is inserted into the pin hole A441 and the pin hole B411. A protruding support block 111 is provided at the end of the guide tube 11.

[0024] When the dust collection box 4 is assembled at the bottom of the housing 1, the control pin 47 is inserted into the pin hole A441 and the pin hole B411. The control rod 41 drives the movable ring B12 to move upward, and the movable ring B12 is separated from the guide tube 11. When it is necessary to remove and clean the dust collection box 4, the pin 47 is pulled out. At this time, under the action of gravity, the bottom end of the first rod body is inserted into the through hole provided on the dust collection box 4 to form a relative seal. At this time, the bottom end of the movable ring B12 rests on the convex support block 111, that is, the movable ring B12 and the guide tube 11 form a seal. At this time, the dust collection box 4 can be removed for cleaning.

[0025] Specifically, a cylindrical body 45 with an internal movable cavity 46 is provided on the outer wall of the guide sleeve A44; a through hole 461 for the pin 47 to pass through is provided at the end of the guide sleeve A44, and a limiting protrusion ring 471 that moves within the movable cavity 46 is provided on the outer wall of the pin 47.

[0026] Based on the above, in order to facilitate the up-and-down movement of the movable ring B12, a guide rod B15 is connected to the connecting frame 14 located around the control rod 41, and a guide sleeve B43 that cooperates with the guide rod B15 is provided on the inner bottom side of the dust collection box 4.

[0027] It is known that, in one feasible implementation, a first threaded structure is provided on the outer wall of the bottom end of the housing 1, and a second threaded structure is provided on the inner wall of the opening end of the dust collection box 4, which is threadedly connected to the first threaded structure.

[0028] It is known that, in a feasible implementation, such as Figure 4 The telescopic module 38 provided in this application includes a guide cylinder 381 and a movable column 382 that are guided together. An electromagnet 384 is provided on the bottom side of the guide cylinder 381, and a magnet 383 is provided at the bottom end of the movable column 382. The striking action is achieved by electromagnetic drive, which has a fast response speed and precise control. The intensity and frequency of dust removal can be flexibly controlled by adjusting the frequency and duration of the current switching. At the same time, when the electromagnet 384 is energized, it generates a magnetism opposite to that of the magnet 383 at the bottom end of the movable column 382, ​​driving the movable column 382 to move upward. When the electromagnet 384 is de-energized, it resets under the action of gravity, driving the striking ring 33 to strike the filter assembly 2, thus completing the dust removal action of the filter assembly 2.

[0029] Of course, in another embodiment, the telescopic module 38 can be a cylinder, a telescopic motor, etc.
