Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a filter that facilitates filter element replacement. Background Technology

[0002] A filter is a device used to separate and filter solid particles and liquids in a mixture. It is usually made of porous or fibrous materials. Filters are widely used in various industries and fields, such as chemical, pharmaceutical, and water treatment industries. The main function of a filter is to remove solid particles and impurities from a mixture to improve the purity and quality of the product. A filter is mainly composed of a cylinder, filter screen, and sewage discharge section.

[0003] Some existing filters typically only have one filter element inside the cylinder. During filtration, as the water passes through the filter element, impurities are blocked. Larger substances tend to obstruct the surface of the filter element's openings, reducing the surface area for the filter to flow out and lowering its filtration efficiency. Therefore, after a period of use, the filter screen needs to be disassembled for cleaning or replacement. Furthermore, in these filters, the cover is fixed to the cylinder by a flange. When the filter element needs to be replaced, multiple bolts need to be loosened using tools. After opening the cylinder, the fasteners securing the filter element to the inner wall of the cylinder need to be removed one by one, and then the fasteners installed on the new filter element to secure it to the cylinder. This process is cumbersome and time-consuming.

[0004] Therefore, those skilled in the art have provided a filter that facilitates filter element replacement to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] Example 1: As Figure 1-8 The filter includes a filter body 1 and a filter element body 2. A top cover 3 is provided at the upper end of the filter body 1. An installation assembly is provided on the inner wall of the filter body 1, allowing the filter element body 2 to be detachably installed on the inner wall of the filter body 1. A connecting assembly for connecting the top cover 3 is provided on the outer wall of the filter body 1. The installation assembly includes an installation ring 41. An installation seat 31 is fixedly installed on the top of the inner wall of the top cover 3. A first sliding groove 3102 is formed on the outer wall of the installation seat 31, and the installation ring 41 is slidably installed on the outer wall of the installation seat 31 through the first sliding groove 3102. An installation sleeve 42 is fixedly installed on the upper end of the installation ring 41. The mounting ring 41 has hanging rods 43 fixedly installed on all four sides of its lower end; the filter element body 2 has a first groove 21 on its upper inner wall, and limit blocks 22 are fixedly installed on all four sides of its outer wall. The limit blocks 22 have connecting grooves 2201 on their inner walls; the top cover 3 has an mounting block 32 fixedly installed on its upper end, and a rotating rod 52 is rotatably installed on the inner wall of the mounting block 32. A rotating block 51 is fixedly installed on the upper end of the rotating rod 52, and a mounting sleeve 42 is threadedly connected to the lower outer wall of the rotating rod 52; the mounting block 32 has a second groove 3201 on its inner wall, and a positioning bolt 33 is threadedly installed on its inner wall.

[0033] The specific practical scenario of this embodiment is as follows: Sealing rubber gaskets are fixedly installed on opposite sides of the filter body 1 and the top cover 3. A raised ring is provided at the upper end of the filter body 1, and a concave groove matching the raised ring is opened on the inner wall of the lower end of the top cover 3, resulting in a sealed connection between the filter body 1 and the top cover 3. The lower end of the mounting base 31 can be inserted into the first groove 21, and a sealing gasket is provided on the opposite side of the mounting base 31 and the filter element body 2. The sealing gasket fills the gap between the mounting base 31 and the filter element body 2, thus achieving a sealed connection between the mounting base 31 and the filter element body 2. The mounting ring 41 can pass through the first sliding groove 3102 on the mounting base 31. The outer wall slides up and down, and the upper end of the mounting ring 41 is fixedly connected to the mounting sleeve 42. When the rotating block 51 is rotated, the rotating rod 52 can rotate. The rotating rod 52 is a threaded rod, and the rotating rod 52 is threadedly connected to the mounting sleeve 42. Therefore, when the rotating rod 52 rotates, the mounting sleeve 42 can move up and down. When the positioning bolt 33 is rotated, the positioning bolt 33 can rotate forward or backward towards the inner wall of the second groove 3201. The positioning bolt 33 can abut against the outer wall of the rotating rod 52. When the positioning bolt 33 is fully tightened, the friction between the positioning bolt 33 and the rotating rod 52 is too great, so that the rotating rod 52 cannot rotate, which can limit the mounting ring 41. The rod 43 is arc-shaped. The connecting groove 2201 on the inner wall of the limiting block 22 matches the outer wall of the hanging rod 43. The upper inner wall of the hanging rod 43 has a fitting groove. The height of the hanging rod 43 on the left side of the fitting groove is the same as that of the connecting groove 2201. When the filter element body 2 is placed directly below the mounting base 31, rotating the filter element body 2 counterclockwise will allow the left side of the hanging rod 43 to fit into the inner wall of the connecting groove 2201. As the filter element body 2 rotates, the upper end of the limiting block 22 overlaps with the fitting groove. At this point, pulling down the filter element body 2 will cause the upper end of the inner wall of the limiting block 22 to fit into the bottom of the fitting groove. Then, rotating the rotating block 51 will... The mounting sleeve 42 can drive the mounting ring 41 to move upward, and the hanging rod 43 can drive the filter element body 2 to move upward. The first groove 21 at the upper end of the filter element body 2 is aligned with the lower end of the mounting base 31, and the lower end of the mounting base 31 is completely inserted into the inner wall of the first groove 21, so that the filter element body 2 and the mounting base 31 can be installed together. A limit ring is provided on the outer wall of the rotating rod 52 and inside the second groove 3201. Positioning holes are equidistantly opened on the inner side of the outer wall of the limit ring. When the filter element body 2 and the mounting base 31 are completely fitted together and the two are in a sealed state, the positioning bolt 33 can be inserted into the inner wall of one of the positioning holes to limit the rotating rod 52.

[0034] Example 2: As Figure 1-8The filter includes a filter body 1 and a filter element body 2. A top cover 3 is provided at the upper end of the filter body 1. An installation assembly is provided on the inner wall of the filter body 1, allowing the filter element body 2 to be detachably installed on the inner wall of the filter body 1. A connecting assembly is provided on the outer wall of the filter body 1 for connecting to the top cover 3. The connecting assembly includes a first connecting ring 61 and a second connecting ring 62. The first connecting ring 61 is fixedly installed on the outer wall of the top cover 3, and the second connecting ring 62 is fixedly installed on the outer wall of the filter body 1. Insert plates 611 are fixedly installed on both sides of the lower end of the first connecting ring 61, and the second connecting ring 62... The inner walls on both sides are provided with slots that match the insert plate 611. Threaded rods 63 are rotatably installed on the inner walls on both sides of the second connecting ring 62. Handles 631 are fixedly installed on the opposite sides of the threaded rods 63 on both sides. Limiting sleeves 65 are threadedly connected to the outer walls of the opposite sides of the threaded rods 63 on both sides. Pull rods 64 are provided on the inner walls of the handles 631. Threaded holes 6201 are provided on the inner walls at both ends of the second connecting ring 62 and on both sides of the threaded rods 63. Second sliding grooves are provided on the inner walls at both ends of the second connecting ring 62 and on the outer walls of the threaded rods 63. Limiting sleeves 65 are slidably installed on the inner walls of the second sliding grooves.

[0035] The specific practical scenario of this embodiment is as follows: The second slide groove connects to the slot. When the handle 631 is rotated, it can drive the threaded rod 63 to rotate, so that the limiting sleeve 65 on the outer wall of the threaded rod 63 can approach or move away from the slot; one end of the pull rod 64 has a thread on its outer wall. The pull rod 64 is slidably installed on the inner wall of the handle 631. When the pull rod 64 is rotated to adjust the position of the limiting sleeve 65, and the limiting sleeve 65 passes through the slot, the length of the second slide groove is sufficient, and the pull rod 64 can rotate to a horizontal state. At this time, the pull rod 64 can be aligned with the threaded hole 620. Inside the filter body 1, rotating the pull rod 64 allows it to be threaded into the threaded hole 6201. The pull rod 64 can be installed inside the threaded hole 6201, fixing the handle 631 so that the handle 631 cannot be rotated. The inner wall of the insert plate 611 has a second slot that matches the outer wall of the limiting sleeve 65. The limiting sleeve 65 can be inserted into the inner wall of the second slot, fixing the insert plate 611 to the inner wall of the second connecting ring 62, so that the second connecting ring 62 cannot be separated from the first connecting ring 61, thus fixing the filter body 1 and the top cover 3 together.

[0036] The above structures and principles are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0037] The working principle of this utility model is as follows: When the filter element body 2 needs to be replaced, loosen the pull rod 64 so that the pull rod 64 is away from the threaded hole 6201. Then, rotate the threaded rod 63 by the handle 631 so that the limiting sleeve 65 connected to the threaded outer wall of the threaded rod 63 moves outward away from the insert plate 611. At this time, the top cover 3 can be removed. Loosen the positioning bolt 33 so that the positioning bolt 33 is not in contact with the rotating rod 52. Rotate the rotating rod 52 by the rotating block 51 so that the mounting sleeve 42 connected to the threaded outer wall of the rotating rod 52 moves downward, so that the hanging rod 43 moves downward, so that the filter element body 2 is separated from the mounting base 31. At this time, push the rotating filter element body 2 upward so that the hanging rod 43 abuts against the bottom of the connecting groove 2201. Then rotate the filter element body 2 clockwise. During the rotation, the hanging rod 43 separates from the limiting block 22 through the connecting groove 2201. At this time, the filter element body 2 can be completely separated from the top cover 3. The reverse operation can be used to install the new filter element body 2 inside the filter body 1.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
