Description

Technical Field

[0001] This invention relates to the field of filters, and in particular to a precision filter structure. Background Technology

[0002] Filters are one of the basic auxiliary devices in industrial production and are widely used. In industrial production, liquids containing impurities enter the filter for filtration, thereby effectively removing the impurities and making the liquid meet the requirements.

[0003] For example, the filter media with publication number CN210186535U can achieve the above purpose, but it has the following problems: 1. The filtration area in contact with substances such as gas or liquid is small, resulting in poor filtration efficiency; 2. The filter cylinder is suspended by only supporting the connecting ring with a limit rod. When the equipment is running, the filter cylinder is prone to causing the connecting ring to shake, which causes it to move up and down in the shell. This is not good for the safety of the filter cylinder and will affect the filtration effect. Summary of the Invention

[0004] The purpose of this invention is to provide a precision filter structure.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A precision filter structure includes a shell composed of an upper cylinder and a lower cylinder. The bottom end of the upper cylinder and the top end of the lower cylinder are provided with flanges, and the two sets of flanges are fixed together by bolts. An inlet and an outlet are respectively provided on the top two sides of the side wall of the lower cylinder. An inclined plate is provided inside the lower cylinder to separate the inlet and the outlet. A support ring is provided on the inner side wall of the lower cylinder to support the edge of the inclined plate. A pressure ring is provided at the top edge of the inclined plate to press it down, and the pressure ring is connected to the inner side wall of the upper cylinder by a vertical rod.

[0007] A filter cylinder extending to the bottom wall of the lower cylinder is provided in the middle of the inclined plate. Multiple sets of arched parts protrude outward on the side wall of the filter cylinder. A spiral tube I is also fixed at the bottom of the filter cylinder. A stud is provided on the bottom wall of the lower cylinder inside the spiral tube I. A spiral tube II is provided between the stud and the spiral tube I and is screwed and fixed to both.

[0008] Preferably, the vertical rod is staggered from the outlet.

[0009] Preferably, the bottom wall of the lower cylinder is a horizontal structure, and a sealing layer is provided at the bottom of the lower cylinder.

[0010] Preferably, the top of the spiral tube II is higher than the horizontal plane of the top of the spiral tube I and the stud, wherein a crossbar is provided inside the spiral tube II above the stud.

[0011] Preferably, a drain pipe is provided at the bottom of the side wall of the lower cylinder.

[0012] The beneficial effects of this invention are as follows: In this invention, liquid or gas enters the lower cylinder through the inlet and flows through the holes on the side wall of the arched part and the side wall of the filter cylinder. The filtered gas or liquid is discharged through the outlet. During this process, the filtration area is increased by passing through the holes on the side wall of the arched part and the side wall of the filter cylinder, thereby improving the filtration efficiency. At the same time, the arched part can effectively strengthen the pressure resistance of the filter cylinder. Furthermore, the screw tube II is screwed to the screw tube I and the stud, which not only locks and fixes the bottom of the filter cylinder, but also effectively prevents it from swinging under pressure. While the support ring and the pressure ring fix the inclined plate, the inclined plate can also fix the top of the filter cylinder. In this way, the stability of the filter cylinder is improved, and it is also convenient for its subsequent disassembly and installation. Attached Figure Description

[0016] The following examples, in conjunction with the appendix, illustrate the concepts. Figure 1-2 The technical solution of the present invention will be further described in detail below.

[0017] A precision filter structure includes a housing 1 consisting of an upper cylinder 101 and a lower cylinder 102. Flanges 2 are provided at the bottom of the upper cylinder 101 and the top of the lower cylinder 102, and the two sets of flanges 2 are fixed together by bolts. An inlet 3 and an outlet 4 are respectively provided on the top two sides of the side wall of the lower cylinder 102. An inclined plate 5 is provided inside the lower cylinder 102 to separate the inlet 3 and the outlet 4. A support ring 6 is provided on the inner side wall of the lower cylinder 102 to support the edge of the inclined plate 5. A pressure ring 7 is provided at the top edge of the inclined plate 5 to press it down, and the pressure ring 7 is connected to the inner side wall of the upper cylinder 101 via a vertical rod 8. The vertical rod 8 is staggered from the outlet 4.

[0018] A filter cylinder 9 extending to the inner bottom wall of the lower cylinder 102 is provided in the middle of the inclined plate 5. Multiple sets of arched parts 10 protrude outward on the side wall of the filter cylinder 9. A spiral tube I11 is also fixed in the bottom of the filter cylinder 9. A stud 12 is provided on the inner bottom wall of the lower cylinder 102 inside the spiral tube I11, and a spiral tube II13 is provided between the stud 12 and the spiral tube I11 and is screwed and fixed to both.

[0019] In this embodiment, the bottom wall of the lower cylinder is a horizontal structure, and a sealing layer is provided at the bottom of the lower cylinder.

[0020] like Figure 1 As shown, the top of the solenoid II13 is higher than the horizontal plane of the top of the solenoid I11 and the stud 12, and a crossbar 14 is provided inside the solenoid II13 above the stud 12.

[0021] In this embodiment, a drain pipe is provided at the bottom of the lower cylinder side wall 102.

[0022] During installation, place the inclined plate 5 on the support ring 6, and at the same time, place the filter cylinder 9 tightly against the sealing layer at the bottom of the lower cylinder 102. At this time, grab the crossbar 14 and insert the screw tube II 13 into the screw tube I 11 and sleeve it on the stud 12. While rotating the screw tube II 13, screw it into the screw tube I 11 and the stud 12, thereby locking and fixing the bottom of the filter cylinder 9 to the bottom of the lower cylinder 102. At the same time, place the upper cylinder 101 on the top of the lower cylinder 102. The upper cylinder 101 is pressed against the top edge of the inclined plate 5 by the pressure ring 7 driven by the vertical rod 8, and the two sets of flanges 2 are locked and fixed by bolts. In this way, the upper cylinder 101 and the lower cylinder 102 are locked and fixed to form a complete shell 1.

[0023] Liquid or gas enters the lower cylinder 102 through inlet 3 and flows through the side wall apertures of the arched part 10 and the side wall apertures of the filter cylinder 9. The filtered gas or liquid is discharged through outlet 4. In this process, the filtration area is increased by passing through the side wall apertures of the arched part 10 and the side wall apertures of the filter cylinder 9, thereby improving the filtration efficiency. At the same time, the arched part 10 can effectively strengthen the pressure resistance of the filter cylinder 9.

[0024] In the above process, the screw tube II13 is screwed to the screw tube I11 and the stud 12, which not only locks and fixes the bottom of the filter cylinder 9, but also effectively prevents it from swinging under pressure. While the support ring 6 and the pressure ring 7 fix the inclined plate 5, the inclined plate 5 can also fix the top of the filter cylinder 9. In this way, the stability of the filter cylinder 9 is improved, and it is also convenient for its subsequent disassembly and installation.

[0025] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
