Description

Technical Field

[0001] This utility model relates to the field of filter cartridge technology, specifically an industrial dust removal filter cartridge. Background Technology

[0002] Industrial dust collector filter cartridges are devices used to filter and purify dust generated during industrial production processes. They are widely used in industries such as mining, metallurgy, chemical, power, and building materials, and are of great significance for improving working environments, reducing production costs, and ensuring production safety. The main function of industrial dust collector filter cartridges is to capture and collect dust particles suspended in the air.

[0003] Industrial dust collector filter cartridges are mostly long and cylindrical, installed inside industrial dust collectors. During actual operation, airflow impact is a significant issue, greatly affecting their service life and filtration performance. Due to uneven airflow distribution, some areas of the filter cartridge experience excessively high airflow impact forces. This localized impact not only disrupts the overall stress balance of the filter cartridge but also generates significant stress concentration within a short period. Under these harsh conditions for extended periods, the filter cartridge is prone to deformation, leading to decreased filtration accuracy; in severe cases, the filter cartridge may even break, rendering the filtration function ineffective and impacting the normal operation of the entire system, increasing maintenance costs and operational risks. Therefore, this paper proposes an industrial dust collector filter cartridge to address these problems. Utility Model Content

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figure 1-5 As shown, an industrial dust collector filter cartridge includes a filter cartridge body 1 and a dust collector chamber 2. An air outlet chamber 3 is fixedly installed on one side of the dust collector chamber 2. Threaded interfaces 4 are respectively opened on the upper and lower sides of the outer side wall of the air outlet chamber 3. An installation port is opened on the side wall of the dust collector chamber 2 corresponding to the threaded interface 4. A sealing ring is fixedly installed inside the installation port to improve the sealing performance between the installation port and the connector 5. The connector 5 is threadedly connected to the inner wall of the threaded interface 4. One end of the connector 5 is fixedly connected to one end of the filter cartridge body 1. A support assembly 6 is installed on the outer side of the filter cartridge body 1. The support assembly 6 includes a protective cylinder 61. One end of the protective cylinder 61 is rotatably connected to the inner side wall of the dust collector chamber 2. A rotating cylinder 62 is fixedly connected to the other end of the protective cylinder 61. The other end of the rotating cylinder 62 is rotatably connected to the inner side wall of the dust collector chamber 2. A plurality of ventilation holes 63 are opened on the surface of the protective cylinder 61. A support ring 64 is fixedly connected to the inner wall of the protective cylinder 61. An opening 65 is opened on the surface of the connector 5.

[0025] Specifically, when installing the filter cartridge body 1, the filter cartridge body 1 is inserted into the interior of the protective cylinder 61 through the threaded interface 4 and the installation port. Then, the connector 5 is connected to the threaded interface 4 to quickly fix the filter cartridge body 1. The filter cartridge body 1 can be quickly removed for replacement or cleaning by screwing on the connector 5, which is convenient for use. During use, the protective cylinder 61 and the support ring 64 cooperate to support the filter cartridge body 1, improving the impact resistance and stability of the filter cartridge body 1. This can effectively prevent the dust collector filter cartridge from being damaged in the event of an impact. The airflow containing dust enters the interior of the protective cylinder 61 through the ventilation hole 63 and is filtered by the filter cartridge body 1, thereby increasing the airflow resistance, reducing the airflow speed, and reducing the airflow impact. The protective cylinder 61 can reduce the impact force of the airflow on the filter cartridge body 1.

[0026] One end of the protective cylinder 61 is fixedly connected to a spring telescopic rod 66, one end of the spring telescopic rod 66 is fixedly connected to a rotating disk 67, two connecting posts 68 are fixedly connected to the surface of the rotating disk 67, and two connecting holes 7 are fixedly connected to the outer wall of one end of the filter cylinder body 1.

[0027] Specifically, when the filter cartridge body 1 is inserted into the protective cylinder 61, one end of the filter cartridge body 1 abuts against the connecting post 68, causing the spring telescopic rod 66 to retract. When the protective cylinder 61 rotates, it drives the spring telescopic rod 66, the rotating disk 67, and the connecting post 68 to rotate. When the connecting post 68 rotates to align with the connecting hole 7, the spring telescopic rod 66 extends, causing the connecting post 68 to insert into the interior of the connecting hole 7, thus realizing the transmission connection between the protective cylinder 61 and the filter cartridge body 1. Through the rotatable filter cartridge body 1, the airflow can fully contact the surface of the filter cartridge body 1, thereby avoiding the filter cartridge body 1 from being subjected to uneven force and deformation due to local airflow impact.

[0028] An air outlet end 8 is fixedly provided on the upper surface of the air outlet chamber 3.

[0029] Specifically, after the airflow passes through the filter body 1, it enters the connector 5 and then enters the outlet chamber 3 through the opening 65, before being discharged from the outlet end 8.

[0030] The surfaces of the dust removal chamber 2 and the exhaust chamber 3 are connected to an air inlet 10 through and fixedly connected. The upper and lower surfaces of the air inlet 10 are respectively provided with rectangular air inlets 11. The surfaces of the air inlet 10 and the rotating cylinder 62 are equipped with rotating components 9.

[0031] Specifically, the air containing dust flows into the air inlet 10 and flows out from the air outlet toward the filter cartridge body 1 for filtration.

[0032] The rotating assembly 9 includes a rotating shaft 91, the outer wall of which is rotatably connected to the center of the air inlet 10. A gear 93 is fixedly connected to one end of the rotating shaft 91 located outside the air inlet 10. Gears 94 are meshed above and below the gear 93 respectively. The inner wall of the gear 94 is fixedly connected to the outer wall of the rotating cylinder 62. An impeller 92 is fixedly connected to one end of the rotating shaft 91 located inside the air inlet 10.

[0033] Specifically, when the airflow passes through the inlet 10, it drives the impeller 92 to rotate. The impeller 92 drives the rotating shaft 91 to rotate. The rotating shaft 91 drives the gear 1 93 to rotate. The gear 1 93 drives the two gears 2 94 to rotate. The gears 2 94 drive the rotating cylinder 62 to rotate. The rotating cylinder 62 drives the protective cylinder 61 and the filter cartridge body 1 to rotate, so that the impact point of the airflow changes continuously, avoiding the airflow from being continuously concentrated in a certain local position of the filter cartridge body 1. Thus, the filter cartridge body 1 reduces the continuous impact force on the local area and reduces the possibility of local deformation or damage to the filter cartridge body 1.

[0034] A partition plate 95 is rotatably connected to the outer wall of the rotating shaft 91 outside the air inlet 10. The outer wall of the partition plate 95 is fixedly connected to the inner wall of the dust removal chamber 2. The rotating cylinder 62 passes through the partition plate 95. Sealing rings are fixedly installed at the intersection of the partition plate 95, the rotating cylinder 62, and the rotating shaft 91 to improve the sealing performance.

[0035] Specifically, the separator layer is used to isolate dust and prevent dust from adhering to the tooth grooves of gear 93 and gear 94 and causing motion interference.

[0036] Working principle: When installing the filter cartridge body 1, insert the filter cartridge body 1 through the threaded interface 4 and the installation port into the interior of the protective cylinder 61. Then connect the connector 5 to the threaded interface 4 to quickly fix the filter cartridge body 1. The filter cartridge body 1 can be quickly removed for replacement or cleaning by screwing on the connector 5, which is convenient for use. During use, the protective cylinder 61 and the support ring 64 cooperate to support the filter cartridge body 1, improving the impact resistance and stability of the filter cartridge body 1. This can effectively prevent the dust collector filter cartridge from being damaged in the event of an impact. The airflow containing dust enters the interior of the protective cylinder 61 through the ventilation hole 63 and is filtered by the filter cartridge body 1, thereby increasing the airflow resistance, reducing the airflow speed, and reducing the airflow impact. The protective cylinder 61 can reduce the impact force of the airflow on the filter cartridge body 1.

[0037] When the filter cartridge body 1 is inserted into the protective cylinder 61, one end of the filter cartridge body 1 abuts against the connecting post 68, causing the spring telescopic rod 66 to retract. When the protective cylinder 61 rotates, it drives the spring telescopic rod 66, the rotating disk 67, and the connecting post 68 to rotate. When the connecting post 68 rotates to align with the connecting hole 7, the spring telescopic rod 66 extends, causing the connecting post 68 to insert into the interior of the connecting hole 7, thus realizing the transmission connection between the protective cylinder 61 and the filter cartridge body 1.

[0038] When the airflow passes through the inlet 10, it drives the impeller 92 to rotate. The impeller 92 drives the rotating shaft 91 to rotate. The rotating shaft 91 drives the gear 1 93 to rotate. The gear 1 93 drives the two gears 2 94 to rotate. The gears 2 94 drive the rotating cylinder 62 to rotate. The rotating cylinder 62 drives the protective cylinder 61 and the filter body 1 to rotate, so that the impact point of the airflow changes continuously, avoiding the airflow from being concentrated in a certain local position of the filter body 1. Thus, the filter body 1 reduces the continuous impact force on the local area and reduces the possibility of local deformation or damage to the filter body 1.
