Description

Technical Field

[0001] This utility model belongs to the field of ventilation network dust removal, specifically, it relates to a workshop ventilation network dust removal device. Background Technology

[0002] Most existing workshop ventilation systems use fixed air mesh as the basic filtration unit to block airborne dust particles. Because these meshes are constantly exposed to high-speed airflow and high dust concentrations, fine dust particles easily accumulate at the mesh's crossover points and metal frames, forming a thick layer over time. If not cleaned promptly, the effective ventilation area of ​​the mesh will significantly decrease, leading to reduced airflow and a substantial increase in air resistance. To maintain the original airflow, the fans must increase their power, resulting in increased energy consumption. Severe localized blockages in the mesh can also cause airflow short-circuiting or localized negative pressure, making the overall system circulation unstable.

[0003] In existing equipment, the cleaning methods for ventilation networks are still relatively primitive. Typically, the entire network needs to be removed from the mounting frame, and then dust removed manually by tapping, knocking, or using simple vibrating tools. This method not only requires shutting down the ventilation system, affecting the production environment, but also necessitates frequent entry and exit of operators into the ductwork, resulting in a heavy workload and harsh working conditions. Furthermore, during disassembly and cleaning, dust adhering to the network easily disperses into the workshop air, causing secondary dust pollution, affecting worker health and workplace cleanliness. Moreover, most network screens are fixed inside narrow frames, limiting the operational space during cleaning. Deeply embedded dust is difficult to remove completely; usually, only surface dust is cleaned, leaving fine dust deep within the network, significantly reducing the cleaning effect. Over time, the ventilation capacity of the network will continuously decline, requiring more frequent disassembly, replacement, or manual cleaning, resulting in high maintenance costs and difficulty in ensuring long-term stable system operation.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Please see Figure 1-6 As shown, this embodiment provides a workshop ventilation dust removal device, including a connecting frame 1, with ramps on both sides of the connecting frame 1, and a ventilation net 2 installed inside the connecting frame 1;

[0034] A rotating rod 3 is rotatably connected to the middle part of the flange 6 structure, and a mounting plate 4 is fixedly connected to the axial part of the air net 2. An eccentric wheel 5 corresponding to the position of the mounting plate 4 is located in the middle part of the rotating rod 3, which is used to push the connecting frame 1 away from the flange 6.

[0035] A flange 6 is provided on the first side of the connecting frame 1. An elastic component is fixedly connected to one side of the flange 6, and the elastic component and the connecting frame 1 cooperate to realize the positioning of the connecting frame 1.

[0036] An annular sealing ring 7 is fixedly connected to the side of the connecting frame 1 near the outer wall of the flange 6, and the sealing ring and the flange 6 are tightly fitted to achieve a seal between the connecting frame 1 and the flange 6.

[0037] A rotating ring is rotatably connected to the inner wall of the flange 6 structure. A scraper 8 is fixedly connected to one side of the rotating ring and is attached to the slope to scrape off residual dust on the slope.

[0038] By setting ramps on both sides of the connecting frame 1 and installing the air net 2 inside, combined with the eccentric wheel 5 pushing, the return elastic component and the sealing ring structure between the flanges 6, the air net 2 can achieve periodic displacement and shaking during operation, thereby shaking off the dust attached to the air net 2. At the same time, when the connecting frame 1 is far away from the flange 6, a gap will be formed between it and the flange 6, which facilitates the subsequent dust discharge. Meanwhile, the scraper 8 at the ramp is driven by the rotating ring to simultaneously clean the accumulated dust on the ramp surface.

[0039] In this embodiment, the elastic component includes a connecting cylinder 9, with a sliding rod 10 slidably fitted inside the connecting cylinder 9. A connecting disc located inside the connecting cylinder 9 is fixedly connected to the lower end of the sliding rod 10. A spring 11, sleeved around the sliding rod 10, is fixedly connected between one side of the connecting disc and the inner wall of the connecting cylinder 9. A connecting piece 12 is fixedly connected to one end of the sliding rod 10, and one end of the connecting piece 12 is fixedly connected to the outer wall of the connecting frame 1. The elastic component employs a matching structure of the connecting cylinder 9, sliding rod 10, connecting disc, and spring 11, allowing the connecting frame 1 to automatically return to its original position without additional mechanisms after being pushed by the eccentric wheel 5.

[0040] In this embodiment, a fixing plate 13 is fixedly connected above the flange 6, and a servo motor 14 is fixedly connected above the fixing plate 13. The output end of the servo motor 14 passes through the fixing plate 13 and is fixedly connected between the flange 6 and the rotating rod 3. The servo motor 14 makes it easier for the eccentric wheel 5 to rotate and increases the degree of automation.

[0041] In this embodiment, a bevel gear 15 is fixedly connected to the circumference of the upper end of the rotating rod 3. A bevel gear ring 16 is provided on one side of the rotating ring, meshing with the bevel gear 15. The meshing between the bevel gear 15 and the bevel gear ring 16 enables the rotation of the rotating ring. The meshing of the bevel gear 15 on the rotating rod 3 with the bevel gear ring 16 on the rotating ring allows the rotating rod 3 to synchronously drive the rotating ring. Using this structure, the scraper 8 forms a continuous and uniform scraping action on the slope, effectively removing dust accumulated on the slope surface.

[0042] In this embodiment, a ring body 17 is fixedly connected to the inner wall of the bevel gear ring 16. A first annular groove adapted to the ring body 17 is formed on the circumferential side of the inner wall of the flange 6, and the ring body 17 is rotatably connected in the first annular groove. By setting the ring body 17 on the inner wall of the bevel gear ring 16 and rotatably connecting the ring body 17 in the first annular groove on the inner wall of the flange 6, stable circumferential support can be provided for the bevel gear ring 16, so that it will not shake, wobble, or be suspended during high-speed or long-term operation.

The L-shaped shielding frame 18 provided on the inner wall of the flange 6 keeps the bevel gear 15 and the bevel gear ring 16 within the shielding range, which can effectively prevent dust particles carried in the airflow from entering the gear meshing area.

[0044] In this embodiment, a connecting ring 19 is fixedly connected to one side of the wind net 2, and a connecting rod 20 is fixedly connected to the side of the scraper 8 facing the wind net 2. The connecting rod 20 is rotatably connected to one side of the connecting ring 19, and a telescopic rod 21 is fixedly connected between the scraper 8 and the rotating ring. Through the linkage structure of the connecting ring 19, the connecting rod 20 and the telescopic rod 21, the scraper 8 can automatically adjust its position when the connecting frame 1 swings back and forth, so that the scraper 8 always fits against the slope surface.

[0045] In this embodiment, a positioning ring 22 is fixedly connected to one side of the connecting rod 20, and a second annular groove for the positioning ring 22 to rotate is provided on one side of the connecting ring 19. The positioning ring 22 can block the second annular groove, reducing the occurrence of dust entering the second annular groove.
