Technical Field

[0001] This utility model relates to filter structure, and in particular to a straight-through T-shaped guide rail filter element. Background Technology

[0002] T-type filters were originally used as coarse filtration devices for pipelines. Their core function is to intercept solid impurities (such as rust and welding slag) in fluids and protect equipment such as pumps and valves. They are named for their unique "T"-shaped structure and come in various types, including direct-flow, forward-baffle, and reverse-baffle types. Their basic design emphasizes a large flow area, low pressure loss, and manual cleaning.

[0003] In the prior art, Chinese utility model patent application number "201520044252.4" discloses a T-type filter, in which the filter cartridge is set at an angle on the partition plate, so the bottom of the filter cartridge is also set at an angle to allow fluid to enter. However, the angled bottom of the filter cartridge and the angled partition plate cannot be positioned for rotational speed, which can easily lead to misalignment or improper installation. Therefore, a structure is needed to solve the above problems. Utility Model Content

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0034] Example 1:

[0035] like Figures 1 to 5 As shown, a straight-through T-shaped guide rail filter includes a T-shaped cylinder 1, which is an inverted T-shape. The left end of the T-shaped cylinder 1 is the inlet 11, the right end is the outlet 13, and the top of the cylinder is the replacement port 12. The replacement port 12 is connected to a maintenance cover 5 via a flange. An inclined baffle 3 is provided between the inlet 11 and the outlet 13 of the T-shaped cylinder 1. The inclined baffle 3 has an inclination angle of 40 degrees to 60 degrees. The inclined baffle 3 is welded to the inside of the T-shaped cylinder 1. A water passage hole is provided in the center of the inclined baffle 3. A filter chamber 2 is formed inside the T-shaped cylinder 1 above the inclined baffle 3. The filter chamber 2 extends upward to the replacement port 12. A filter element 4 is provided in the filter chamber 2. The filter element 4 is pulled out from the replacement port 12.

[0036] like Figure 4 As shown, the filter element 4 includes a top cover 41 and a filter cylinder 43. The bottom of the filter cylinder 43 extends downwards through the filter element. The top cover 41 is welded to the top of the filter cylinder 43. The surface of the filter cylinder 43 is provided with filter holes. The bottom of the filter cylinder 43 is engaged with the inclined baffle 3 and is inclined. The bottom of the filter cylinder 43 is connected to the water passage hole. The inclined baffle 3 is provided with a limiting part that engages with the bottom of the filter cylinder 43. The limiting part is arranged around the bottom of the filter cylinder 43.

[0037] like Figures 2 to 3 As shown, the bottom edge of the filter cartridge 43 includes a lower arc-shaped section 45 and an upper arc-shaped section 46. The upper arc-shaped section 46 is higher than the lower arc-shaped section 45 in the height direction. The bottom of the upper arc-shaped section 46 and the bottom of the lower arc-shaped section 45 are engaged with the top of the inclined partition 3 and are arranged at an angle. At the same time, the limiting part includes a limiting ring. The position where the limiting ring engages with the lower arc-shaped section 45 is a vertical section 31, and the position where the limiting ring engages with the upper arc-shaped section 46 is an inclined section 32. The top of the inclined section 32 is inclined toward the upper arc-shaped section 46.

[0038] like Figure 1 and Figure 4As shown, the top of the top cover 41 is provided with a support connection part, which plays the role of axially positioning and supporting the filter element 4. The top of the support connection part abuts against the inspection cover 5. The specific structure of the support connection part is that the support connection part is an arc-shaped piece 42 made of stainless steel. The middle part of the arc-shaped piece 42 abuts against the bottom of the inspection cover 5. The arc-shaped piece 42 is semi-circular. The two ends of the arc-shaped piece 42 in the length direction are welded and fixed to the top of the top cover 41. In use, the arc-shaped piece 42 allows the operator to lift the filter element 4. At the same time, when the inspection cover 5 presses down the arc-shaped piece 42, it positions and fixes the filter element 4.

[0039] like Figure 4 and Figure 5 As shown, guide plates 44 are welded on both radial sides of the filter cylinder 43. The guide plates 44 are symmetrically arranged at 180 degrees on the outer side wall of the filter cylinder 43. The guide plates 44 extend along the axial direction of the filter chamber 2. The T-shaped cylinder 1 is provided with a guide groove 21 on the side wall of the filter chamber 2 that cooperates with the guide plates 44. The guide groove 21 extends along the axial direction of the filter chamber 2.

[0040] like Figure 4 and Figure 5 As shown, the specific forming structure of the guide groove 21 is as follows: the guide groove 21 can be directly set on the inner surface of the T-shaped cylinder 1, or the guide groove 21 can be directly milled on the track 22, and then the track 22 is welded and fixed in the filter chamber 2. That is, the side wall of the filter chamber 2 extends radially inward to form the track 22. The track 22 is symmetrically arranged at 180 degrees in the filter chamber 2. The track 22 extends along the axial direction of the filter chamber 2, and the guide groove 21 is set in the track 22. A more optimized solution is that the track 22 includes oppositely arranged clamping plates 23, the clamping plates 23 extend along the axial direction of the filter chamber 2, and the guide groove 21 is set between adjacent clamping plates 23.

[0041] Working principle:

[0042] Fluid enters through the left inlet 11 of the T-shaped cylinder 1, impacts the inclined baffle 3, and then flows upward through the water passage on the inclined baffle 3 into the filter cartridge 43. The fluid flows upward within the filter cartridge 43, where impurities are intercepted. Finally, the fluid is discharged through the right outlet 13 of the T-shaped cylinder 1. During maintenance, the maintenance cover 5 is opened to expose the replacement port 12. The filter element 4 is pulled out of the guide groove 21 using the arc-shaped plate 42. During installation, the filter element 4 is held and inserted downwards, aligning the guide plate 44 with the guide groove 21 until the upper arc section 46 engages with the inclined section 32 and the lower arc section 45 engages with the vertical section. Finally, the maintenance cover 5 is locked in place using the flange to secure the filter.

[0043] Example 2:

[0044] like Figure 6As shown, the difference between Embodiment 2 and Embodiment 1 is that the structure of the inspection cover 5 is improved. Specifically, the bottom of the inspection cover 5 is recessed inward to form a limiting groove 51. The limiting groove 51 cooperates with the arc-shaped piece 42. The center of the arc-shaped piece 42 is provided with a first connecting hole 52, and the top of the inspection cover 5 is provided with a second connecting hole 53. A limiting post 54 is provided through between the first connecting hole 52 and the second connecting hole 53. The bottom of the limiting post 54 abuts against the bottom of the arc-shaped piece 42, and the top of the limiting post 54 is threaded with a nut 55.
