Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridge dust collectors, in particular to a quick-detachable filter cartridge of a filter cartridge dust collector. Background Art

[0002] A filter cartridge is a cylindrical element used for filtering. It is generally divided into filter cartridges for filtering gaseous media and filtering liquid media. Filter cartridges for filtering liquid media are generally installed inside pipe filters. Their appearance is often conical, so they are also called conical filters. Filter cartridges on the market are mainly installed by six-ear snap fasteners.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the existing quick-release filter cartridges for filter cartridge dust collectors are mostly fixed with bolts. In this process, the use of bolts for fixing is not only difficult to install, but also prone to thread slippage, which leads to loose installation. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a quick-detachable filter cartridge of a filter cartridge dust collector.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a quick-detachable filter cartridge of a filter cartridge dust collector, comprising a filter cartridge body, a fixing ring is fixedly arranged on the bottom surface of the filter cartridge body, a fixing cylinder is installed on the outer wall of the fixing ring, a plurality of fixing grooves are provided on the upper surface of the fixing cylinder, a plurality of mounting grooves are provided on the inner walls of the fixing grooves, a plurality of fixing blocks are distributed in an array on the outer wall of the fixing ring, the fixing blocks and the fixing ring are fixed to each other, the fixing blocks are slidably connected to the mounting groove, and the fixing blocks are rotatably connected to the fixing groove.

[0006] By adopting the above technical solution, when the staff needs to install the filter cartridge body, the staff needs to connect the filter cartridge body and the fixed cartridge. At this time, the staff needs to align the fixed block with the fixed groove, and further, the staff needs to move the filter cartridge body in the direction close to the fixed cartridge, so that the fixed block slides in the fixed groove, so that the bottom surface of the fixed block abuts against the inner bottom wall of the fixed groove. At this time, the staff needs to rotate the filter cartridge body, and then rotate the fixed block in the installation groove, so that the side wall of the fixed block abuts against the inner wall of the installation groove, and then complete the installation of the filter cartridge body. In this process, the difficulty of installing the filter cartridge body is reduced.

[0007] Furthermore, a sliding groove is provided on the inner bottom wall of the fixed groove, and a blocking groove opposite to the sliding groove is provided on the bottom surface of the fixed block. A sliding rod is slidably arranged in the sliding groove, and a first spring is fixedly arranged on the bottom surface of the sliding rod. The other end of the first spring is fixedly arranged on the inner bottom wall of the sliding groove, and the sliding rod is slidably connected to the blocking groove.

[0008] By adopting the above technical solution, when the side wall of the fixing block abuts against the inner wall of the installation groove, the sliding groove and the blocking groove face each other. At this time, the sliding rod slides upward under the action of the first spring, and then the end of the sliding rod away from the first spring slides into the blocking groove, thereby fixing the fixing ring, thereby reducing the probability of the fixing ring rotating when subjected to external force, thereby reducing the probability of the filter cartridge body rotating when subjected to external force, thereby improving the stability of the device, thereby improving the firmness of the installation.

[0009] Furthermore, a limiting groove is provided on the upper surface of the sliding rod, a limiting rod is fixedly arranged on the inner top wall of the blocking groove, and the limiting rod is slidably connected to the limiting groove.

[0010] By adopting the above technical solution, when the sliding rod slides upward under the action of the first spring, the limit rod and the limit slot slide relative to each other, so that the limit rod slides completely into the limit slot, thereby reducing the probability of the sliding block being separated from the blocking slot when subjected to external force, thereby improving the stability of the device and thus improving the firmness of the installation.

[0011] Furthermore, the diameter of the upper end of the sliding rod limiting rod is greater than the diameter of the lower end.

[0012] By adopting the above technical solution, the diameter of the upper end of the sliding rod limit rod is greater than the diameter of the lower end, which reduces the difficulty of the limit rod sliding into the limit groove, thereby reducing the work difficulty of the staff.

[0013] Furthermore, the limiting rod is made of rubber material.

[0014] By adopting the above technical solution, the rubber has good elasticity, and the limit rod made of rubber material increases the maximum static friction upper limit between the limit rod and the limit groove, thereby reducing the probability of separation between the limit groove and the limit rod, thereby improving the stability of the device.

[0015] Furthermore, the upper end of the sliding rod is provided with a rounded corner.

[0016] By adopting the above technical solution, the upper end of the sliding rod is provided with a rounded corner, which reduces the probability that the sliding rod blocks the fixed rod when the fixed block rotates. In this process, when the fixed block rotates, the sliding rod slides into the sliding groove under the action of the fixed block, thereby reducing the probability that the sliding rod blocks the fixed rod when the fixed block rotates.

[0017] Furthermore, the bottom end of the fixing block is provided with a chamfer.

[0018] By adopting the above technical solution, chamfering reduces the difficulty for workers to fix the fixing block and the fixing groove, thereby reducing the difficulty of the workers' work.

[0019] Furthermore, a mounting ring is fixedly provided on the upper end of the filter cartridge body, and a plurality of arc-shaped grooves are arranged in a circumferential array on the outer wall of the mounting ring.

[0020] By adopting the above technical solution, the installation ring and the arc groove reduce the difficulty for the staff to rotate the filter cartridge body, thereby reducing the work difficulty of the staff.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the staff needs to install the filter cartridge body, the staff needs to connect the filter cartridge body and the fixed cartridge. At this time, the staff needs to align the fixed block with the fixed slot. Further, the staff needs to move the filter cartridge body in the direction close to the fixed cartridge, so that the fixed block slides in the fixed slot, so that the bottom surface of the fixed block abuts against the inner bottom wall of the fixed slot. At this time, the staff needs to rotate the filter cartridge body, so that the fixed block rotates in the installation slot, so that the side wall of the fixed block abuts against the inner wall of the installation slot, and then complete the installation of the filter cartridge body. In this process, the difficulty of installing the filter cartridge body is reduced for the staff;

[0023] 2. In the present application, when the side wall of the fixed block abuts against the inner wall of the installation groove, the slide groove is opposite to the blocking groove. At this time, the slide rod slides upward under the action of the first spring, and then the end of the slide rod away from the first spring slides into the blocking groove, thereby fixing the fixing ring, thereby reducing the probability of the fixing ring rotating when subjected to external force, thereby reducing the probability of the filter cartridge body rotating when subjected to external force, thereby improving the stability of the device, thereby improving the firmness of the installation;

[0024] 3. In the present application, when the slide rod slides upward under the action of the first spring, the limit rod and the limit slot slide relative to each other, so that the limit rod slides completely into the limit slot, thereby reducing the probability of the slider being separated from the blocking slot when subjected to external force, thereby improving the stability of the device and thus improving the firmness of the installation.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0033] like Figure 1-6 As shown, the embodiment of the present application discloses a quick-detachable filter cartridge of a filter cartridge dust collector, including a filter cartridge body 1, a fixing ring 11, a fixing cylinder 12, a fixing block 13, a sliding rod 3, a first spring 31 and a limiting rod 4. The filter cartridge body 1 is a cylindrical structure, which is used to filter impurities. The fixing ring 11 is a circular ring structure, and its axis is vertical. The fixing ring 11 is fixedly arranged on the bottom surface of the filter cartridge body 1. The fixing cylinder 12 is a circular ring structure, and its axis coincides with the axis of the fixing ring 11. The fixing cylinder 12 is installed on the outer wall of the fixing ring 11, and a plurality of fixing grooves 2 are provided on the upper surface of the fixing cylinder 12, and a plurality of fixing grooves 2 are provided on the inner walls thereof. A plurality of fixing blocks 13 are provided and are distributed in an array on the outer wall of the fixing ring 11, and the fixing blocks 13 and the fixing ring 11 are fixed to each other, and the fixing blocks 13 are slidably connected to the fixing grooves 21, and the fixing blocks 13 are rotatably connected to the fixing grooves 2.

[0034] When the staff needs to install the filter cartridge body 1, the staff needs to connect the filter cartridge body 1 with the fixed cartridge 12. At this time, the staff needs to align the fixed block 13 with the fixed slot 2. Further, the staff needs to move the filter cartridge body 1 in the direction close to the fixed cartridge 12, so that the fixed block 13 slides in the fixed slot 2, so that the bottom surface of the fixed block 13 abuts against the inner bottom wall of the fixed slot 2. At this time, the staff needs to rotate the filter cartridge body 1, so that the fixed block 13 rotates in the installation slot 21, so that the side wall of the fixed block 13 abuts against the inner wall of the installation slot 21, and then complete the installation of the filter cartridge body 1. In this process, the difficulty of installing the filter cartridge body 1 is reduced.

[0035] A sliding groove 22 is provided on the inner bottom wall of the fixed groove 2, and a blocking groove 23 is provided on the bottom surface of the fixed block 13 to face the sliding groove 22. The sliding rod 3 is a round rod-shaped structure with a vertical axis. The sliding rod 3 is slidably arranged in the sliding groove 22, and the sliding rod 3 is slidably connected to the blocking groove 23. One end of the first spring 31 is fixedly arranged on the bottom surface of the sliding rod 3, and the other end of the first spring 31 is fixedly arranged on the inner bottom wall of the sliding groove 22.

[0036] When the side wall of the fixing block 13 abuts against the inner wall of the installation groove 21, the sliding groove 22 is opposite to the blocking groove 23. At this time, the sliding rod 3 slides upward under the action of the first spring 31, so that the end of the sliding rod 3 away from the first spring 31 slides into the blocking groove 23, thereby fixing the fixing ring 11, thereby reducing the probability of the fixing ring 11 rotating when subjected to external force, thereby reducing the probability of the filter cartridge body 1 rotating when subjected to external force, thereby improving the stability of the device, thereby improving the firmness of the installation.

[0037] A limiting groove 24 is provided on the upper surface of the slide rod 3 , and the limiting rod 4 is fixedly disposed on the inner top wall of the blocking groove 23 , and the limiting rod 4 is slidably connected to the limiting groove 24 .

[0038] When the slide bar 3 slides upward under the action of the first spring 31, the limit rod 4 and the limit slot 24 slide relative to each other, so that the limit rod 4 slides completely into the limit slot 24, thereby reducing the probability of the slider being separated from the blocking slot 23 when subjected to external force, thereby improving the stability of the device and thus improving the firmness of the installation.

[0039] In order to reduce the difficulty of the staff's work, the diameter of the upper end of the slide bar 3 limit rod 4 is greater than the diameter of the lower end. The diameter of the upper end of the slide bar 3 limit rod 4 is greater than the diameter of the lower end, which reduces the difficulty of the limit rod 4 sliding into the limit groove 24, thereby reducing the difficulty of the staff's work.

[0040] In order to improve the stability of the device, the limit rod 4 is made of rubber material. Rubber has good elasticity. The limit rod 4 made of rubber material increases the upper limit of the maximum static friction between the limit rod 4 and the limit groove 24, thereby reducing the probability of the limit groove 24 and the limit rod 4 separating from each other, thereby improving the stability of the device.

[0041] In order to reduce the probability that the slide bar 3 blocks the fixed rod when the fixed block 13 rotates, a rounded corner 5 is provided at the upper end of the slide bar 3. The rounded corner 5 at the upper end of the slide bar 3 reduces the probability that the slide bar 3 blocks the fixed rod when the fixed block 13 rotates. In this process, when the fixed block 13 rotates, the slide bar 3 slides into the slide groove 22 under the action of the fixed block 13, thereby reducing the probability that the slide bar 3 blocks the fixed rod when the fixed block 13 rotates.

[0042] In order to reduce the difficulty of the work of the staff, the bottom end of the fixing block 13 is provided with a chamfer 6. The chamfer 6 reduces the difficulty of the staff to fix the fixing block 13 and the fixing groove 2, thereby reducing the difficulty of the staff's work.

[0043] In order to reduce the difficulty of the staff's work, a mounting ring 7 is fixedly provided on the upper end of the filter cartridge body 1, and a plurality of arc grooves 71 are arranged in a circumferential array on the outer wall of the mounting ring 7. The mounting ring 7 and the arc grooves 71 reduce the difficulty of the staff to rotate the filter cartridge body 1, thereby reducing the difficulty of the staff's work.

[0044] The use principle of a quick-detachable filter cartridge of a filter cartridge dust collector in this embodiment is as follows: when the staff needs to install the filter cartridge body 1, the staff needs to connect the filter cartridge body 1 and the fixed cartridge 12 to each other. At this time, the staff needs to align the fixed block 13 with the fixed slot 2. Further, the staff needs to move the filter cartridge body 1 in the direction close to the fixed cartridge 12, so that the fixed block 13 slides in the fixed slot 2, so that the bottom surface of the fixed block 13 abuts against the inner bottom wall of the fixed slot 2. At this time, the staff needs to rotate the filter cartridge body 1, so that the fixed block 13 rotates in the installation slot 21, so that the side wall of the fixed block 13 abuts against the inner wall of the installation slot 21, and then complete the installation of the filter cartridge body 1. In this process, the difficulty of installing the filter cartridge body 1 for the staff is reduced.
