Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dust removal technology, specifically relating to a pulse dust collector. Background Technology
[0002] With the development of modern industry, dust pollution of the environment is becoming increasingly serious, and it is necessary to control dust pollution. Pulse bag dust collector is a dry dust collection device, also known as a filter dust collector. It is a dust collection device that uses bag filter elements made of woven fiber to capture solid particles in dusty gas. Its working principle is that when dust passes through the filter cloth fibers, it is intercepted by contact with the fibers due to inertia. The dust collected on the filter bag is periodically removed by the dust removal device and falls into the ash hopper, and then discharged through the ash discharge system.
[0003] However, when the filter bags in a pulse dust collector are handling gas containing dust, the filter bags will wear down. Since the dust particles entering the dust collector vary in size, the filter bags will wear down even faster when filtering large dust particles in the gas, ultimately affecting the dust removal efficiency of the pulse dust collector.

[0015] (3) Beneficial effects
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention, by setting up a filtration mechanism, allows the connecting plate to be placed at the air inlet on the front side of the pulse dust collector body. The connecting plate is then slid down until the mounting blocks on both sides of the connecting plate move into the support grooves within the support blocks. This fixes the connecting plate between the support blocks and positions it in front of the air inlet of the pulse dust collector body. Consequently, the gas drawn into the pulse dust collector body is filtered through the dust filter. Large dust particles in the air are blocked at the front end of the dust filter and do not enter the pulse dust collector body, preventing excessive wear on the filter bags in the pulse dust collector body caused by filtering large dust particles.
[0018] This invention, through the setting of a processing unit, ensures that when the air to be filtered enters the main body of the pulse dust collector, it passes through the fan blades during the process of entering the main body of the pulse dust collector after being filtered by the dust screen. The fan blades are blown and rotated, which in turn causes the rotating rod to rotate, driving the connecting rod and scraper at the front end to rotate. As the scraper rotates on the surface of the dust screen, it scrapes off large dust particles attached to the outside of the dust screen, and the scraper slides continuously towards the edge of the dust screen as it is curved. This prevents large dust particles from continuously accumulating on the dust screen during the filtration process, avoiding clogging of the dust screen and affecting the dust removal effect.

Detailed Implementation
[0026] 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.
[0027] This specific embodiment is a pulse dust collector, and its structural schematic diagram is shown below. Figures 1 to 3 As shown, the device includes a pulse dust collector body 1. A high-pressure air pump 2 is installed at the upper end of the pulse dust collector body 1. A filter mechanism is installed at the air inlet at the lower end of the pulse dust collector body 1. The filter mechanism includes a connecting plate 301 connected to the lower front side of the pulse dust collector body 1. A dustproof net 302 is fixedly connected to the middle position inside the connecting plate 301. Mounting blocks 303 are fixedly connected to the upper and lower ends of the left and right sides of the connecting plate 301. Support blocks 304 are fixedly connected to the four corners of the air inlet on the left and right front sides of the pulse dust collector body 1. A support groove is opened at the front end of the support block 304 near the connecting plate 301. The outer side of the mounting block 303 is slidably connected to the inner side of the support groove. The rear side of the connecting plate 301 is slidably connected to the air inlet at the front side of the pulse dust collector body 1. After placing the connecting plate 301 at the air inlet on the front side of the pulse dust collector body 1, the connecting plate 301 is then slid down until the mounting blocks 303 on both sides of the connecting plate 301 move down into the support grooves in the support blocks 304. This fixes the connecting plate 301 between the support blocks 304 and positions it in front of the air inlet of the pulse dust collector body 1. Consequently, the gas drawn into the pulse dust collector body 1 is filtered by the dust filter 302. Large dust particles in the air are blocked at the front end of the dust filter 302 and do not enter the pulse dust collector body 1, thus preventing excessive wear of the filter bags in the pulse dust collector body 1 when filtering large dust particles.
[0028] A rubber pad is affixed to the rear edge of the connecting plate 301. When the connecting plate 301 is installed at the air inlet on the front side of the pulse dust collector body 1, the rubber pad on the rear side of the connecting plate 301 will contact the air inlet on the front side of the pulse dust collector body 1, so that the contact point between the connecting plate 301 and the pulse dust collector body 1 remains sealed. This ensures that the air entering the pulse dust collector body 1 can only pass through the dust filter 302 before entering the pulse dust collector body 1.
[0029] Cooperate Figure 4 and Figure 5 As shown, processing units are provided at both ends of the connecting plate 301. Each processing unit includes a fixed plate 401 fixedly connected to the inner side of the air inlet at the lower end of the pulse dust collector body 1. A bearing 402 is installed in the middle of the fixed plate 401. A rotating rod 403 is fixedly connected to the inner side of the bearing 402. A fan blade 404 is fixedly connected to the outer side of the rotating rod 403 in front of the fixed plate 401. A limit ring 405 is fixedly connected to the inner rear side of the air inlet inside the pulse dust collector body 1. The outer rear end of the rotating rod 403 is rotatably connected to the inner side of the limit ring 405. A connecting rod 406 is connected to the front end of the rotating rod 403. A rectangular block 407 is fixedly connected to the rear side of the connecting rod 406. A bolt 408 is connected inside the connecting rod 406. A rectangular groove is formed at the front end of the rotating rod 403, and a threaded groove is formed at the middle position behind the rectangular groove at the front end of the rotating rod 403. A through-hole is formed inside the connecting rod 406 and the rectangular block 407. The outer side of the bolt 408 is slidably connected to the inner side of the hole, the outer side of the rectangular block 407 is slidably connected to the inner side of the rectangular groove, and the outer rear end of the bolt 408 is slidably connected to the inner side of the threaded groove. The front side of the rotating rod 403 abuts against the rear side of the connecting rod 406. By removing and installing the bolt 408 inside the connecting rod 406 located at the front end of the rotating rod 403, the connecting rod 406 can be disassembled and installed at the front end of the rotating rod 403, facilitating the disassembly and assembly of the connecting rod 406 when disassembling and assembling the dustproof net 302.
[0030] A scraper 409 is fixedly connected to the outer front end of the connecting rod 406, and an arc-shaped frame 410 is fixedly connected to the lower front side of the connecting plate 301. A rotating hole is provided in the middle of the interior of the dustproof net 302. The outer side of the connecting rod 406 is rotatably connected to the inner side of the rotating hole, and the rear side of the scraper 409 is slidably connected to the front side of the dustproof net 302. The scraper 409 is a curved plate. When the air to be filtered enters the main body 1 of the pulse dust collector, it passes through the fan blades 404 during the process of being filtered by the dust filter 302. The fan blades 404 are blown and rotated, which in turn causes the rotating rod 403 to rotate, driving the connecting rod 406 and the scraper 409 at the front end to rotate. As the scraper 409 rotates on the surface of the dust filter 302, it scrapes off the large dust particles attached to the outside of the dust filter 302. The scraper 409 slides continuously towards the edge of the dust filter 302 as it is curved, thus preventing the large dust particles from continuously accumulating on the dust filter 302 during the filtration process and avoiding clogging of the dust filter 302, which would affect the dust removal effect.
[0031] Working principle: When the pulse dust collector is working, the high-pressure air pump 2 draws external air through the dust filter 302 at the front of the air inlet to remove large particles of dust before it enters the main body 1 of the pulse dust collector. As the air enters the main body 1, it passes behind the fan blades 404, which blows the fan blades 404 to make them rotate. This causes the rotating rod 403 to rotate, which in turn drives the connecting rod 406 and the scraper 409 at the front to rotate. As the scraper 409 rotates on the surface of the dust filter 302, it scrapes off the large dust particles attached to the outside of the dust filter 302. Then, the large dust particles slide along the curved surface of the scraper 409 towards the edge of the dust filter 302, moving away from the center of the dust filter 302, thus ensuring the filtration effect of the dust filter 302. After the pulse dust collector finishes working and is shut down, the dust falls into the lower arc frame 410 and is collected and cleaned.
[0032] All technical features in this embodiment can be freely combined according to actual needs.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
