Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, and specifically relates to a bag dust collector. Background Art

[0002] A bag dust collector, also known as a filter dust collector, is a dry high-efficiency dust collector. It is a dust removal device that uses a bag-type filter element made of a fiber fabric to capture solid particles in the dust-containing gas.

[0003] During the use of the bag dust collector, the dust removal treatment of the dust bag is carried out through the internal compressed air system. During the process of the dust bag being impacted by compressed air for dust removal, due to the action of the impact pressure, the dust bag will become loose. After the dust bag becomes loose, its filtration area and filtration effect are affected, resulting in a decrease in the dust removal efficiency, making the dust unable to be effectively captured, thus affecting the use of the entire bag dust collector.

[0004] Therefore, there is an urgent need for a bag dust collector to solve the above problems. Summary of the Utility Model

It also includes multiple groups of bag dust removal components arranged inside the box body for bag dust removal. Multiple placement holes for placing the bag dust removal components are opened on the partition. The bag dust removal component includes a mounting ring and a base. The mounting ring and the base are installed and connected through multiple mounting frames. A dust removal bag is sleeved between the mounting ring and the base. A first support component for supporting the inner bottom of the dust removal bag is arranged on the base, and a second support component for supporting the inner side of the dust removal bag is arranged on the outer side of the base.

It also includes multiple groups of bag dust removal components for bag dust removal arranged inside the box body 101. Multiple placement holes for placing the bag dust removal components are opened on the partition 104. The bag dust removal component includes a mounting ring 201 and a base 202. The mounting ring 201 and the base 202 are installed and connected through multiple groups of mounting frames 203. A dust removal bag 204 is sleeved between the mounting ring 201 and the base 202. A first support component for supporting the inner bottom of the dust removal bag 204 is arranged on the base 202, and a second support component for supporting the inner side of the dust removal bag 204 is arranged on the outer side of the base 202;

[0022] It should be noted here that: in the process of purifying dust gas by using the bag dust removal component, through the first support component and the second support component, the mutually supporting effect on the inner bottom and the inner side of the dust removal bag 204 keeps the dust removal bag 204 in a taut state during use, reduces the probability of relaxation occurring on the dust removal bag 204, and further ensures the effect of removing dust from the dust-laden air by the bag dust removal method.

[0023] Multiple groups of the second support components are arranged around the base 202;

[0024] It should be noted here that: through multiple groups of the second support components, the support effect is ensured.

[0025] The second support component includes a mounting groove 501 opened on the outer side of the base 202. A support plate 502 is slidably connected to the mounting groove 501, and an elastic component for elastically pushing the support plate 502 is arranged inside the mounting groove 501;

[0026] It should be noted here that: in the process of purification treatment, through the elastic pushing action of each spring 603 on the elastic component on the support plate 502, the support plate 502 on each mounting groove 501 abuts against the inner side of the dust removal bag 204.

[0027] The elastic component includes multiple sleeves 601 fixed inside the mounting groove 501. A sliding rod 602 is slidably connected to each sleeve 601. One end of the sliding rod 602 is fixed to the support plate 502. A spring 603 is sleeved on the outer side of the sleeve 601, and both ends of the spring 603 abut against the mounting groove 501 and the support plate 502 respectively;

[0028] It should be noted here that: through the sleeve 601 and the slide bar 602, the telescopic movement of the support plate 502 after being stressed is guided, and through the spring 603, it is convenient to push the support plate 502 with elastic force.

[0029] The first support assembly includes a chute 301 formed on the base 202, a support rod 302 is slidably connected to the chute 301, and a gravity assembly for pushing the support rod 302 is provided at the end of the support rod 302;

[0030] It should be noted here that: through the gravity action of the gravity block 402 on the bearing frame 401, the support rod 302 on the chute 301 is pushed against, and during the pushing process, one end of the support rod 302 abuts against the bottom inside the dust removal bag 204.

[0031] The gravity assembly includes a bearing frame 401 fixed at the end of the support rod 302, and a gravity block 402 is placed on the bearing frame 401;

[0032] It should be noted here that: through the gravity block 402 on the bearing frame 401, it is convenient to push the support rod 302.

[0033] Working principle: During the use of the bag filter, the dust removal bag 204 is sleeved between the mounting ring 201 and the base 202. After the sleeving is completed, the entire bag dust removal assembly is placed on the placement hole of the partition plate 104. The dust-containing gas entering through the air inlet 102 on the box body 101 is filtered by the dust removal bag 204 on the bag dust removal assembly, and the clean gas after filtration and purification is discharged outward through the air outlet 103, completing the purification operation of the bag filter for the dust air;

[0034] During the process of using the bag dust removal assembly to purify the dust-containing gas, through the gravity action of the gravity block 402 on the bearing frame 401, the support rod 302 on the chute 301 is pushed against. During the pushing process, one end of the support rod 302 abuts against the bottom inside the dust removal bag 204, and during the purification process, through the elastic pushing action of each spring 603 in the elastic force assembly on the support plate 502, the support plate 502 on each mounting groove 501 abuts against the inside of the dust removal bag 204. Through the abutting and supporting actions of the support rod 302 and multiple groups of support plates 502 on the bottom inside and the inside of the dust removal bag 204, the dust removal bag 204 is kept in a taut state during use, reducing the probability of slack on the dust removal bag 204, and further ensuring the dust removal effect of the dust air by the bag dust removal method.
