Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to an anti-clogging bag dust collector. Background Art

[0002] The bag dust collector is a dry dust filtering device that is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag dust collector, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. The gas containing finer dust is retained when passing through the filter material, so that the gas is purified.

[0003] After searching, the applicant found that a Chinese patent disclosed "an anti-clogging bag dust collector", and its publication (announcement) number is "CN220779416U". The patent mainly includes a box body, a mounting frame is fixedly connected to the box body, four fixing plates are fixedly connected under the mounting frame, and two stabilizing plates are fixedly connected under the fixing plates. During use, the bag dust collector can knock on the surface of the bag so that dust and debris adhering to the surface of the bag can fall off from the surface of the bag. At the same time, by repeatedly knocking on the surface of the bag, the cleaning effect of the bag dust collector is effectively guaranteed. However, in the above-mentioned prior art, mechanical vibration cleaning can usually only produce vibrations of a certain amplitude. For some dust with high viscosity or tightly adhered, the cleaning effect may not be ideal, and mechanical vibration may cause repeated mechanical stress on the bag. Long-term use can easily cause damage and deformation of the bag, shortening the service life of the bag. Improvements are needed. To this end, we propose an anti-clogging bag dust collector.

Repeat this many times, and the dust on the inner wall of the ash hopper can be collected at the bottom, which is convenient for one-time cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] Please see the attached Figure 1 - Attachment Figure 5 , an anti-clogging bag dust collector, an anti-clogging bag dust collector, comprising a dust collection box 1 and a dust collection bag 8, the bottom of the dust collection box 1 is fixedly connected to a ash hopper 2, the upper end of the interior of the dust collection box 1 is fixedly connected to a mounting bracket 10, the interior and outside of the dust collection box 1 are provided with a dust cleaning device 4, the dust cleaning device 4 comprises a fixing bracket 401, the fixing bracket 401 is connected to an air storage tank 402 through a tightening belt 403, the air storage tank 402 is connected to a blowing pipe 405 through an electromagnetic pulse valve 404, the blowing pipe 405 is away from the electromagnetic pulse valve 404. The end of the blowing pipe 405 passes through the left side of the dust collection box 1 and is fixedly connected to an air collecting hood 406, the dust collection bag 8 is fixedly installed at the axis of the mounting bracket 10, and the lower ends of the left and right sides of the dust collection box 1 are fixedly connected to two sets of support seats 3, the dust collection box 1 A top cover 6 is provided on the top, a clean air outlet 9 is provided at the left end of the dust removal box body 1 and at the upper end of the mounting frame 10, a dust and gas inlet 7 is provided at the lower end of the dust removal box body 1 and at the mounting frame 10, a vibrating device 5 is provided inside and outside the ash hopper 2, a fixing frame 401 is fixedly installed on the right outer surface of the dust removal box body 1, and the gas storage tank 402 is fixedly installed on the surface of the fixing frame 401. Two tightening belts 403 are provided and fixedly installed on the upper and lower ends of the surface of the fixing frame 401. The two tightening belts 403 are flexibly connected to the outer surface of the gas storage tank 402, an electromagnetic pulse valve 404 is provided at the output end of the gas storage tank 402, and a blowing pipe 405 is fixedly connected to the end of the electromagnetic pulse valve 404 away from the gas storage tank 402. The gas collecting hood 406 is provided directly above the dust bag 8.

[0024] The bottom diameter of the air collecting hood 406 is the same as the diameter of the dust bag 8. The blowing pipe 405 allows the compressed air to be evenly sprayed into each bag, which has a better cleaning effect. However, mechanical vibration may cause incomplete cleaning of some dust bags 8 due to uneven distribution of vibration position and force. The impact of high-pressure airflow on the dust bag 8 is relatively gentle and the action time is short. Mechanical vibration may cause repeated mechanical stress on the dust bag 8. Long-term use may easily cause the dust bag 8 to be damaged and deformed, shortening the service life of the dust bag 8. The electromagnetic pulse valve 404 is controlled by a pulse controller. The pulse controller can be handheld or fixed on the dust collector, which will not be elaborated here.

[0025] Specifically, when it is necessary to clean the dust on the surface of the dust bag 8, the electromagnetic pulse valve 404 opens quickly after receiving the signal, and the compressed air is instantly released from the air tank 402 and sprayed into the dust bag 8 at high speed through the blowing pipe 405 and the air collecting hood 406. The compressed air sprayed out at high speed forms an instantaneous positive pressure in the dust bag 8, causing the dust bag 8 to expand rapidly. During the expansion of the dust bag 8, the dust layer attached to the surface of the dust bag 8 is destroyed and falls off into the ash hopper 2. Subsequently, the electromagnetic pulse valve 404 is closed, and the compressed air stops blowing. The dust bag 8 returns to its original state under the action of its own elasticity and negative pressure, which can enable the dust bag 8 to be cleaned in all directions and prevent dust from clogging the dust bag 8.

[0026] Example 2:

[0027] Please see the attached Figure 1 - Attachment Figure 3 and Figure 6 , and on the basis of Example 1, it is further obtained that the rapping device 5 includes a connecting frame 501, the connecting frame 501 is connected to a fixed plate 504 and an impact ball 505 through a pull rod 502, one end of the pull rod 502 is fixedly connected to a pull block 506, and the surface of the fixed plate 504 away from the impact ball 505 is fixedly connected to a telescopic spring 503, the connecting frame 501 is fixedly connected to the front outer surface of the dust removal box 1, the pull rod 502 is movably connected to the inside of the connecting frame 501, the fixed plate 504 and the impact ball 505 are both arranged inside the ash hopper 2, the pull block 506 is arranged on the front side of the connecting frame 501 and is located outside the ash hopper 2, one end of the telescopic spring 503 away from the fixed plate 504 is fixedly connected to the front inner wall of the ash hopper 2, and the telescopic spring 503 is slidably connected to the circumferential surface of the pull rod 502.

[0028] The impact ball 505 is made of flexible material and will not damage the inner wall of the ash hopper 2. The impact of the impact ball 505 drives the entire ash hopper 2 to vibrate. Moreover, the ash hopper 2 adopts a conical structure design, which facilitates the centralized collection of dust on the inner wall of the ash hopper 2, thereby improving work efficiency.

[0029] Specifically, when dust falls into the ash hopper 2, it tends to stay on the inner wall of the ash hopper 2 and is difficult to clean. At this time, the pull block 506 is pulled, and the telescopic spring 503 is forced to shrink. After stretching to a certain extent, the pull block 506 is released, and the telescopic spring 503 is reset to drive the pull rod 502 to move, so that the impact ball 505 hits the inner wall of the ash hopper 2. Repeating this many times can collect the dust on the inner wall of the ash hopper 2 at the bottom, which is convenient for one-time cleaning.

[0030] Working principle of the utility model: The utility model is an anti-clogging bag dust collector. First, the gas enters the dust collection box 1 through the dust inlet 7, is filtered by the dust bag 8, and finally the clean gas is discharged through the clean gas outlet 9. Thereafter, when the dust bag 8 needs to be cleaned, the electromagnetic pulse valve 404 opens quickly after receiving the signal, and the compressed air is instantly released from the air storage tank 402, and is sprayed into the dust bag 8 at high speed through the blowing pipe 405 and the air collecting hood 406. The compressed air sprayed at high speed forms an instantaneous positive pressure in the dust bag 8, causing the dust bag 8 to expand rapidly. During the expansion of the dust bag 8, the attached The dust layer on the surface of the dust bag 8 is destroyed and falls off into the ash hopper 2. Then, the electromagnetic pulse valve 404 is closed, and the compressed air stops blowing. The dust bag 8 returns to its original state under the action of its own elasticity and negative pressure, so that the dust bag 8 can perform all-round cleaning. When the dust falls into the ash hopper 2, the pull block 506 is pulled, and the telescopic spring 503 is forced to shrink. After stretching to a certain extent, the pull block 506 is released, and the telescopic spring 503 is reset to drive the pull rod 502 to move, so that the impact ball 505 hits the inner wall of the ash hopper 2. Repeat this many times, and the dust on the inner wall of the ash hopper 2 can be collected at the bottom for easy one-time cleaning.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
