When the staff needs to disassemble the filter bag body, the staff removes the cover plate upward. Then, the filter bag body is taken out, thereby reducing the difficulty of the staff in disassembling the filter bag body, thereby reducing the working difficulty of the staff.

[0021] 2、In the application, when the staff covers the cover plate on the bottom ring, in this process, the staff needs to rotate the rotating block, and then the abutting piece is rotated into the fixing groove. Then, when the bottom surface of the cover plate abuts against the upper surface of the mounting ring, the fixing groove and the plug-in groove are opposite. At this time, the staff rotates the rotating block, and then the side wall of the abutting piece abuts against the inner wall of the plug-in groove, thereby reducing the probability of shaking of the cover plate in the working process, thereby improving the stability of the device.

[0022] 3、In the application, when the staff rotates the rotating block, the rotating rod rotates under the action of the rotating block. In this process, the rotating rod limits the rotating block, thereby reducing the probability of deviation of the rotating block, thereby improving the stability of the device.

Obviously, the described embodiments are only part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0029] As shown in Figures 1-4 The present embodiment discloses a liquid filter bag convenient to replace, which comprises a bottom ring 1, a mounting ring 11, a filter bag body 12, a cover plate 13, a limiting ring 14, a rotating block 3, an abutting piece 31, a plug-in groove 32, a rotating rod 4 and a torsional spring 5. The axis of the bottom ring 1 is vertical, and the upper surface of the bottom ring 1 is provided with a mounting groove 15. The mounting ring 11 is circular in cross section, and its axis coincides with the axis of the bottom ring 1. The mounting ring 11 is mounted in the mounting groove 15, and the bottom surface of the mounting ring 11 is provided with a limiting groove 2. The filter bag body 12 is fixedly arranged on the bottom surface of the mounting ring 11, and the cover plate 13 is mounted on the upper surface of the bottom ring 1, and its axis coincides with the axis of the bottom ring 1. The limiting ring 14 is circular in cross section, and its axis coincides with the axis of the bottom ring 1. The limiting ring 14 is fixedly arranged on the inner bottom wall of the mounting groove 15, and the limiting ring 14 and the limiting groove 2 are matched with each other.

[0030] When the staff needs to install the filter bag body 12, the staff needs to install the mounting ring 11 on the inner bottom wall of the mounting groove 15, so that the limiting ring 14 and the limiting groove 2 are matched with each other. Then, the staff covers the cover plate 13 to the bottom ring 1, so that the bottom surface of the cover plate 13 abuts against the upper surface of the mounting ring 11, thereby completing the installation of the filter bag body 12. When the staff needs to disassemble the filter bag body 12, the staff removes the cover plate 13 upward. Then, the filter bag body 12 is taken out, thereby reducing the difficulty of the staff in disassembling the filter bag body 12, and reducing the work difficulty of the staff.

[0031] The inner wall of the mounting groove 15 is symmetrically provided with a fixing groove 21, and the rotating block 3 is provided with two rotating blocks and is arranged in the two fixing grooves 21. The abutting piece 31 is fixedly arranged on the side wall of the rotating block 3, and the side wall of the cover plate 13 is symmetrically provided with the plug-in groove 32, and the side wall of the abutting piece 31 abuts against the inner wall of the plug-in groove 32.

[0032] When the worker covers the cover plate 13 to the bottom ring 1, in the process, the worker needs to rotate the rotating block 3, and then make the abutting piece 31 rotate to the fixing groove 21. Then, when the bottom surface of the cover plate 13 is abutted with the upper surface of the mounting ring 11, the fixing groove 21 is opposite to the plug-in groove 32. At this time, the worker rotates the rotating block 3, and then makes the side wall of the abutting piece 31 abut with the inner wall of the plug-in groove 32, thereby reducing the probability of shaking of the cover plate 13 in the working process, and thereby improving the stability of the device.

[0033] The inner wall of the fixing groove 21 is provided with a rotating groove 22, the rotating rod 4 is in a circular rod structure, the axis is horizontal, the rotating rod 4 is rotationally arranged in the rotating groove 22, and the rotating rod 4 is fixed with the rotating block 3.

[0034] When the worker rotates the rotating block 3, the rotating rod 4 rotates under the action of the rotating block 3, in the process, the rotating rod 4 limits the rotating block 3, thereby reducing the probability of deviation of the rotating block 3, and thereby improving the stability of the device.

[0035] The inner wall of the rotating groove 22 is provided with a reset groove 23, one end of the torsional spring 5 is fixedly arranged on the inner wall of the reset groove 23, and the other end of the torsional spring 5 is fixedly arranged on the side wall of the rotating rod 4.

[0036] When the worker moves the cover plate 13 downward, the cover plate 13 gradually approaches and finally abuts against the abutting piece 31, and then the abutting piece 31 rotates with the rotating block 3 under the action of the cover plate 13. Then, the abutting piece 31 rotates into the fixing groove 21 under the action of the cover plate 13, when the fixing groove 21 is opposite to the plug-in groove 32, the abutting piece 31 rotates into the plug-in groove 32 under the action of the torsional spring 5, the rotating rod 4 and the rotating block 3, and then the side wall of the abutting piece 31 abuts with the inner wall of the plug-in groove 32, in the process, without manual operation of the worker, thereby reducing the working difficulty of the worker.

[0037] In order to improve the stability of the device, the abutting piece 31 is made of elastic material. The abutting piece 31 made of elastic material reduces the probability that the worker moves the cover plate 13 upward and the abutting piece 31 is blocked, thereby improving the stability of the device.

[0038] In order to improve the stability of the device, the upper surface and the bottom surface of the rotating block 3 are provided with a round corner 6. The round corner 6 reduces the probability of collision between the rotating block 3 and the rotating groove 22 when the rotating block 3 rotates, thereby improving the stability of the device.

The supporting piece 7 reduces the probability that the abutting piece 31 is deformed when the worker moves the cover plate 13 downward, thereby improving the stability of the device.

[0040] The working principle of the liquid filter bag convenient to replace in the embodiment is as follows: when a worker needs to install the filter bag body 12, the worker needs to install the mounting ring 11 to the inner bottom wall of the mounting groove 15, and then the limiting ring 14 is matched with the limiting groove 2. Then, the worker covers the cover plate 13 to the bottom ring 1, and then the bottom surface of the cover plate 13 is abutted with the upper surface of the mounting ring 11, so that the installation of the filter bag body 12 is completed. When the worker needs to disassemble the filter bag body 12, the worker removes the cover plate 13 upwards. Then, the filter bag body 12 is taken out, so that the difficulty of the worker in disassembling the filter bag body 12 is reduced, and the working difficulty of the worker is reduced.
