Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a containerized filter element capable of preventing self-rotation. Background Art

[0002] In modern industrial production and environmental treatment, filtration technology plays a vital role, especially in the fields of water treatment, chemical industry, pharmaceutical industry, food processing, etc. An efficient and stable filtration system is the basis for ensuring product quality, meeting environmental protection standards and maintaining continuous operation of production lines. However, with the increasing application of filtration technology, the performance requirements for filtration equipment are also getting higher and higher, especially for the stability and filtration efficiency of filter elements.

[0003] In the traditional cartridge filter design, the filter tube often faces the problem of self-rotation when in operation, especially under conditions of high flow, high pressure difference or external vibration. The self-rotation of the filter element will not only lead to uneven distribution of the filter material, affect the filtration effect, reduce the filtration accuracy, but also cause the equipment to vibrate more, increase energy consumption, and shorten the service life of the filter element.

[0004] For example, the previous generation of filter element structure of our company can refer to the container filter element with good filtering effect disclosed in the application number CN202222374067.4. The filter element tube of this structure is tightened to the upper and lower cover plates by nuts. During operation, it was found that when the water flow is turbulent, the filter element tube is prone to self-rotation and loosening.

[0005] In order to solve this technical problem, our company has redeveloped a cartridge filter element that prevents self-rotation. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a container-type filter element which can prevent self-rotation.

[0007] The technical solution adopted by the utility model is: a container filter element for preventing self-rotation, comprising two cover plates and a plurality of filter element tubes arranged between the two cover plates, the filter element tubes comprising a main pipe section and externally threaded tubes on both ends of the main pipe section, the externally threaded tubes pass through the mounting holes on the cover plates and are locked by nuts, a pressed step that fits the cover plates is formed between the main pipe section and the externally threaded tubes, a positioning column is provided on the pressed step, and a positioning hole matched with the positioning column is provided on the cover plates.

[0008] Furthermore, the positioning column includes a convex column integrally formed with the pressed step and a rubber sleeve sleeved on the convex column.

[0009] Furthermore, the positioning column is a conical structure.

[0010] Furthermore, there are two positioning columns, which are respectively arranged on both sides of the external threaded tube.

[0011] Furthermore, the inner wall of the through hole of the main pipe section is a wave structure.

[0012] Furthermore, the distance between the wave crests of the inner wall of the through hole is 1 / 8-1 / 4 of the length of the main pipe section.

[0013] The beneficial effects of the utility model are:

[0014] 1. Effectively prevent self-rotation: By setting the positioning column and positioning hole, after the filter tube and the cover plate are installed, the positioning column is inserted into the positioning hole to prevent the filter tube from self-rotating during operation, thereby extending the service life of the filter element.

[0015] 2. Easy to disassemble and assemble: External threaded tubes are set at both ends of the filter tube, so that when assembling, the external threaded tube can be directly passed through the installation hole of the cover plate and locked with nuts, which is convenient for disassembly and assembly. It is also convenient to replace a single filter tube to avoid unnecessary waste.
