Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a lightweight multi-layer composite filter element. Background Art

[0002] Textile machines are also called spinning machines, looms, cotton spinning machines, etc. Ancient textile machines were looms driven by manpower. Textile machines are the full name of tools that process raw materials such as thread, silk, and linen into silk thread and then weave them into cloth, such as spinning sinkers, spinning wheels, spindles, pedal looms, as well as modern mechanical looms, modern CNC automatic looms, etc.

[0003] During the textile production process, a large amount of lint, dust, etc. will be generated, which will cause serious pollution to the environment and harm to the human body. Therefore, dust collectors are used to remove dust from the operating environment of textile machines. Among them, the filter element in the dust collector is particularly important as the core component of the dust collector.

[0004] A Chinese patent with announcement number CN219272305U discloses a lightweight composite large-scale cotton-padded filter element, including an inner support frame, an outer support frame, and a cotton core. The inner support frame and the outer support frame are both in the shape of a circular tube. The diameter of the inner support frame is smaller than that of the outer support frame. The inner support frame is placed inside the outer support frame and the inner support frame and the outer support frame are coaxial and concentric; the cotton core is sandwiched between the inner support inner frame and the outer support inner frame; a plurality of connecting rods are provided on the outer edges of the inner support frame and the outer support frame, and the inner support frame and the outer support frame are connected as a whole through the connecting rods.

[0005] The above-mentioned filter element changes the traditional drilling of holes on the fiberglass pipe into a direct skeleton structure, and uses the supporting skeleton with inner core as the main force point. Support rods are used to connect multiple parallel support frames to form an overall structural skeleton. It has high structural strength, large through-hole area and light overall weight, which is more conducive to the filtering needs of large flow rates.

[0006] However, the inner support frame and the outer support frame are connected as a whole through connecting rods. When the cotton core needs to be cleaned and replaced, all the connecting rods need to be removed to take out the cotton core between the inner support frame and the outer support frame, which is cumbersome.

[0007] Therefore, a lightweight multi-layer composite filter element is proposed. Utility Model Content

[0031] The disassembly and assembly parts include an assembly cover 4, which is arranged in an annular shape. An outer limiting annular groove 402 and an inner limiting annular groove 403 are provided on one side of the assembly cover 4. The outer support ring 101 at the end of the outer support frame 1 is clamped in the outer limiting annular groove 402, and the inner support ring 201 at the end of the inner support frame 2 is clamped in the inner limiting annular groove 403. The edge of the outer support ring 101 at the end of the outer support frame 1 is protruding outward, and a plurality of notches 102 are provided on the edge of the outer support ring 101. A clamping block 401 having the same number as the notches 102 is fixedly connected to one side of the assembly cover 4 close to the outer limiting annular groove 402. After the clamping block 401 is inserted from the notch 102, it can be clamped at the edge of the outer support ring 101 by rotation. It should be noted that an assembly cover 4 is provided at the top and bottom of the external support frame 1. In order to prevent the assembly cover 4 from spinning relative to the external support frame 1, a locking component is provided on the assembly cover 4, and a locking component pull rod 501 is provided. An assembly groove 4011 connected to the outer limit annular groove 402 is provided on the top of the assembly cover 4. The upper end of the pull rod 501 slides through the assembly groove 4011 and is fixedly connected to a circular plate 5. The lower end of the pull rod 501 is fixedly connected to a pressure plate 503, and the pressure plate 503 is slidably set in the assembly groove 4011. A spring 502 is sleeved on the pull rod 501, and the upper end of the spring 502 abuts against the inner top of the assembly groove 4011, and the lower end of the spring 502 abuts against the top of the pressure plate 503. A groove 103 is provided on the top of the outer support ring 101, and the lower end of the pull rod 501 can be inserted into the groove 103.
