Description

Technical Field

[0001] This utility model relates to the field of pre-filtration technology, and in particular to a cyclone pre-filter for high efficiency. Background Technology

[0002] Cyclone filtration is a gas-solid / gas-liquid separation technology based on the principle of centrifugal separation. It is widely used in industrial dust removal, fluid purification, and product recycling. The filter element of a pre-filter is a key component of water purification. It is used to purify raw resources and promote their reuse. Filter elements are generally used in filtration industries such as oil filtration and water filtration to remove small amounts of impurities from the filter medium and protect the normal operation of the equipment. When fluid passes through a filter element with a certain precision, impurities are blocked, while clean fluid flows out through the filter element. The application of cyclone filtration technology in the field of pre-filters is mainly reflected in efficient cleaning and impurity interception. Its core is to improve filtration efficiency through fluid dynamics design. The prior art, CN213610132U, discloses a high-efficiency pre-filter, comprising a working cylinder, a cylinder cavity, a sealing ring, a fixing bolt, a sealing cap, a cap cavity, a connecting box, a water inlet head, a rotatable connecting ring structure, a rotatable filter cylinder structure, and a water outlet head. The working cylinder has an internal cylinder cavity; the sealing ring is fitted onto the upper part of the outer wall of the working cylinder; the fixing bolt is threadedly connected to the connection between the working cylinder and the sealing cap; the sealing cap has an internal cap cavity, which is fitted onto the upper part of the outer wall of the working cylinder; the connecting box is placed inside the cap cavity; the water inlet head is threadedly connected to the right side of the sealing cap and the right side of the connecting box. The rotatable filter cylinder structure allows the rotating motor to drive the filter element to rotate, thereby increasing the speed at which water flows out of the filter element and thus improving the filtration effect.

[0003] However, the existing cyclone pre-filter high-efficiency filter devices all use a single filter material for single-pass filtration. The filtration effect cannot be guaranteed by a single pass, which can easily affect subsequent normal use. At the same time, long-term filtration will cause the internal filter element to become dirty, affecting the subsequent filtration effect and normal use, requiring replacement. However, the existing replacement structure is a threaded engagement and rotation method, and subsequent disassembly and replacement also require tools, which is time-consuming and laborious. Utility Model Content

[0004] To overcome the problems of existing cyclone pre-filter high-efficiency filter devices where the filter element structure is connected by threads, requiring tools for disassembly and replacement, and the single filter element structure affecting the filtration effect.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figures 1-5This utility model provides an embodiment: a cyclone pre-filter high-efficiency filter, including a pre-filter housing 1, with connecting pipes on both the left and right sides of the pre-filter housing 1. Both connecting pipes have external threads for pipe connection. A filter sleeve 2 is provided inside the pre-filter housing 1, with a filter cavity 5 inside the filter sleeve 2. A PE filter element 6 is provided inside the filter cavity 5. Connecting seats 3 are fixedly connected to both the upper and lower ends of the filter sleeve 2. Mounting seats 4 are fixedly connected to both the upper and lower ends of the pre-filter housing 1. Each mounting seat 4 has a fixing groove 7 inside, and a mounting assembly is provided inside the fixing groove 7. The mounting assembly includes a mounting block 8, which has a slot 10 inside and a positioning groove 9 inside. There are four positioning grooves 9 arranged in a ring. Below the four positioning grooves 9, there is an annular groove 11 located on the inner wall of the mounting block 8. There are four movable grooves inside the mounting block 8, which are arranged in a ring. Each of the four movable grooves has a plug-in component inside. An elastic component is sleeved on the outside of the plug-in component. The plug-in assembly includes a plug rod 12. A positioning component is fixedly connected to the outside of the plug rod 12. There are four positioning components arranged in a ring. The positioning component has a socket 15 inside.

[0017] The filter sleeve 2 is made of stainless steel wire mesh, which forms a columnar structure through cross-weaving. The PE filter element 6 is located inside the filter inner cavity 5. The PE filter element 6 is made of ultra-high molecular weight polyethylene and provides a secondary filtration effect to enhance filtration. Both ends of the PE filter element 6 are fixedly connected to connecting discs for fixing the PE filter element 6 to the filter sleeve 2. The stainless steel wire mesh material of the outer filter sleeve 2 is high-strength, pressure-resistant, and high-temperature-resistant, providing a primary filtration effect. At the same time, the PE filter element 6 inside the filter sleeve 2 provides secondary filtration. The PE filter element 6 is made of ultra-high molecular weight polyethylene, which is non-toxic, odorless, resistant to organic solvents, and has high physiological safety, thus improving the overall filtration effect.

[0018] The positioning components include positioning blocks 14, which are fixedly connected to insert blocks 16. Insert blocks 16 are inserted into slots 10, and all four positioning blocks 14 are engaged in the four positioning grooves 9. Connecting seat 3 is engaged in the fixing groove 7 for the installation of filter sleeve 2. The insertion component includes an insert rod 12, and the elastic component includes a spring 13. Spring 13 is sleeved on the outside of insert rod 12. Insert rod 12 and spring 13 are both located inside the movable groove. Spring 13 and insert rod 12 are compressed synchronously inside the movable groove while being compressed. The four positioning blocks 14 are engaged in the four positioning grooves 9 and, through displacement, are engaged in the annular groove 11. Through rotation, the positioning blocks 14 are displaced within the annular groove 11 and contact the insert rod 12, allowing for synchronous compression of the insert rod 12 and spring 13. Insert rod 12 is inserted into the insertion hole 15 for the installation of filter sleeve 2. The filter sleeve 2 is installed by aligning the insert blocks 16 at the lower end of the filter sleeve 2 with the insert rod 16. Insert the insert 16 into the slot 10 inside the mounting block 8. At the same time, the four positioning blocks 14 on the outside of the insert 16 are locked into the four positioning slots 9. Continue to move downwards and insert the insert 16 so that the four positioning blocks 14 slowly move into the annular groove 11. By rotating the filter sleeve 2, the four positioning blocks 14 rotate in the annular groove 11 and come into contact with the insert rod 12 and press it. This causes the insert rod 12 and the externally fitted spring 13 to compress synchronously. The insert rod 12 is then inserted into the insertion hole 15 inside the positioning block 14 and fixed. This completes the installation of the filter sleeve 2 and the PE filter element 6. To disassemble, rotate the insert rod 16 in the opposite direction so that the insert rod 12 and the spring 13 are pressed synchronously and disengaged from the insertion hole 15. The four positioning blocks 14 reach the positions of the four positioning slots 9. Pull it upwards so that the insert 16 and the four positioning blocks 14 disengage synchronously. This completes the disassembly.

[0019] During operation, the insert block 16 at the lower end of the filter sleeve 2 is aligned with the four positioning blocks 14 and inserted into the slots 10 and four positioning grooves 9 inside the mounting block 8 below. As the four positioning blocks 14 slowly move into the annular groove 11, the filter sleeve 2 is rotated, causing the four positioning blocks 14 to rotate within the annular groove 11 and contact the insert rod 12 for compression. This causes the insert rod 12 to compress synchronously with the externally fitted spring 13, and the insert rod 12 is inserted into the insertion hole 15 inside the positioning block 14 for fixation. For disassembly, the rotation is reversed. This causes the insertion rod 12 and spring 13 to be pressed synchronously and disengaged from the insertion hole 15, and all four positioning blocks 14 to reach the positions of the four positioning slots 9. Pulling it upwards allows the insertion block 16 to disengage synchronously from the four positioning blocks 14, thus completing the disassembly. The stainless steel wire mesh material of the outer filter sleeve 2 is high-strength, pressure-resistant, and high-temperature-resistant, providing primary filtration. At the same time, secondary filtration is performed through the PE filter element 6 inside the filter sleeve 2. The PE filter element 6 is made of ultra-high molecular weight polyethylene, which is non-toxic, odorless, resistant to organic solvents, and has high physiological safety, thus improving the overall filtration effect.

[0020] Through the above steps, the stainless steel wire mesh material of the outer filter sleeve 2 is high in strength, high pressure resistance, and high temperature resistance, providing a primary filtration effect. At the same time, the PE filter element 6 inside the filter sleeve 2 performs secondary filtration. The PE filter element 6 is made of ultra-high molecular weight polyethylene, which is non-toxic, odorless, resistant to organic solvents, and has high physiological safety, thus improving the overall filtration effect. This solves the problem that the existing cyclone pre-filter high-efficiency filter devices all use threaded connections for the filter element structure, which require tools for disassembly and replacement, and the single filter element structure affects the filtration effect.
