Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a Y-type filter. Background Art

[0002] Y-type filter is a common pipe connection device, usually used to filter impurities and particles in liquid or gas pipelines. Its name comes from the letter "Y" shape it presents. The filter is usually made of metal, plastic or glass. The main function of the Y-type filter is to intercept solid particles, impurities and pollutants in the fluid to ensure the normal operation of the pipeline system and the protection of the equipment. Its working principle is similar to that of a funnel. When the fluid enters from the main pipeline, due to the slow flow rate, solid particles and impurities will be deposited at the bottom of the Y-type filter due to inertia, while the clean fluid continues to be transmitted.

[0003] The Y-shaped filter mainly relies on the filter cylinder therein for filtration. The structure of the filter cylinder itself is cylindrical, and its radius increases from both ends to the middle. It is mainly set in the filter tube, and the surface of the filter cylinder is attached to the inner wall of the filter tube. However, due to its shape during installation, when it is extended into the filter tube, the large radius of the filter cylinder will hinder its extension into the filter tube, making the installation and disassembly of the filter cylinder more difficult.

[0004] Therefore, a Y-type filter is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a Y-type filter.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A Y-type filter comprises an inlet pipe and an outlet pipe which are coaxially arranged, and a filter pipe which is connected to the junction of the two pipes. The radius of the filter pipe is gradually increased from both ends to the middle. A sealing plate is detachably connected to the end of the filter pipe away from the inlet pipe, and a filter screen cylinder which fits the inner wall of the filter pipe is fixedly connected to the end surface of the sealing plate. An adjusting component for adjusting the radius of the filter screen cylinder is arranged on the sealing plate.

[0008] Preferably, a plurality of arc-shaped rods of equal length and evenly spaced are fixedly connected to the inner wall of the filter screen cylinder.

[0009] Preferably, the adjustment assembly includes a connecting rod that passes through the sealing plate, a connecting sleeve that is rotatably connected to one end of the connecting rod, and a plurality of pressure rods that are fixedly connected to the outside of the connecting sleeve, and the ends of the pressure rods that are away from the connecting sleeves are fixedly connected to the arc rods, and the pressure rods are distributed in a circular array at the maximum radius of the filter cylinder.

[0010] Preferably, a connecting ring with a semicircular cross section is fixedly connected to the outer side of one end of the connecting rod, an annular groove is provided on the inner ring of the connecting sleeve, and the connecting ring is slidably connected in the annular groove.

[0011] Preferably, the adjustment assembly also includes a threaded plug, the end of the connecting rod away from the connecting sleeve is coaxially fixedly connected to the threaded plug, the side of the sealing plate away from the filter tube is provided with a threaded groove, and the bottom of the threaded groove is provided with a through groove for the connecting rod to pass through, the inner circumferential wall of the threaded groove is provided with an internal thread, and the threaded plug is threadedly connected to the threaded groove via the internal thread.

[0012] Preferably, a pull ring is fixedly connected to one end of the threaded plug away from the connecting rod.

[0013] Preferably, the end of the filter tube away from the inlet pipe is fixedly connected with a sealing flange, and a plurality of connecting studs are fixedly connected to the end surface of the sealing flange. The sealing plate is provided with a plurality of through holes for the connecting studs to pass through, and the connecting studs are threadedly connected with nuts after passing through the through holes.

[0014] Preferably, ends of the inlet pipe and the outlet pipe that are away from each other are both fixedly connected with connecting flanges.

[0015] The utility model has the following beneficial effects:

[0016] In actual application, the utility model allows the fluid to first enter through the inlet pipe, and then pass through the filter cylinder for filtering to separate the solid particles therein, and the filtered fluid is discharged through the outlet pipe, thereby ensuring the purity of the fluid. The filter cylinder adopts an arc rod as a strength enhancement structure, which can effectively resist the pressure exerted on it by the fluid and avoid deformation and damage. As the filtering time increases, some meshes may be blocked, resulting in a decrease in the filtering effect. In this case, the operator can apply force to the threaded plug through the pull ring to disengage it from the threaded groove and rotate it, thereby driving the displacement of the connecting rod. The connecting rod and the connecting sleeve are connected by relative rotation. The displacement causes the deflection of the pressure rod, thereby pulling the filter cylinder to collapse it, so that it can be taken out for cleaning. The filter cylinder is cleaned by scraping, high-pressure water gun, etc. to remove solid particles on the surface to ensure its filtering effect and smooth fluid flow.

[0024] Among them, Figure 2 and 3 As shown, the radius of the filter tube 3 is gradually increased from both ends to the middle, and the end of the filter tube 3 away from the inlet pipe 2 is detachably connected to the sealing plate 5, and the end of the filter tube 3 away from the inlet pipe 2 is fixedly connected to the sealing flange 4, and a plurality of connecting studs 6 are fixedly connected to the end surface of the sealing flange 4, and a plurality of through holes for the connecting studs 6 to pass through are opened on the sealing plate 5, and the connecting studs 6 are threadedly connected with nuts 7 after passing through the through holes, and a filter screen cylinder 12 that fits the inner wall of the filter tube 3 is fixedly connected to the end surface of the sealing plate 5, and a plurality of arc rods 13 of equal length and evenly spaced are fixedly connected to the inner wall of the filter screen cylinder 12, and an adjusting component for adjusting the radius of the filter screen cylinder 12 is provided on the sealing plate 5.

The ends of the plurality of pressure rods 14 that are away from the connecting sleeve 16 are fixedly connected to the arc rods 13, and the plurality of pressure rods 14 are distributed in a circular array at the maximum radius of the filter screen cylinder 12.

[0027] Among them, the connecting sleeve 16, the pressure rod 14, the threaded plug 8, and the connecting rod 11 are also made of stainless steel, and the cross-sectional area of ​​the pressure rod 14 is larger than the cross-sectional area of ​​the welding points between its two ends and the connecting sleeve 16 and the filter screen cylinder 12, and its welding position is welded by TIG welding.
