Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically relating to an adjustable stainless steel filter. Background Technology

[0002] Stainless steel filters are made of stainless steel such as 304 and 316L, which can resist the erosion of various corrosive media such as acids, alkalis, and salts. They are suitable for corrosive environments such as chemical and pharmaceutical industries. The pore size of the internal filter element can be precisely controlled, with a wide accuracy range from a few micrometers to hundreds of micrometers. It can effectively intercept various tiny impurities, particles, and even bacteria, meeting the filtration accuracy requirements of different industries.

[0003] In practical applications, stainless steel filters need to be precisely connected to sewage pipe openings to ensure the smooth operation of the sewage treatment process. However, since stainless steel filters are mostly independent prefabricated equipment produced in factories in a standardized manner, while the installation of sewage pipe openings is often affected by a variety of factors such as the on-site construction environment, civil engineering structure, and pipeline layout, deviations in size, angle, and position between the two are very likely to occur.

[0004] These errors pose significant challenges to installation, making traditional direct connection methods difficult to implement. Installers often need to spend considerable time and effort on-site adjustments, such as repeatedly cutting and grinding pipes, or using temporary support structures to correct the filter's position. This greatly increases the difficulty of installation. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable stainless steel filter, aiming to solve the problem that stainless steel filters are mostly independent prefabricated devices, produced in a standardized manner in factories; while the installation of sewage pipe outlets is often affected by various factors such as on-site construction environment, civil structure, and pipeline layout, resulting in deviations in size, angle, and position. These errors pose a significant challenge to the installation work, making traditional direct connection methods difficult to implement. Installers often need to spend a lot of time and effort on-site adjustments, such as repeatedly cutting and grinding pipes, or using temporary support structures to correct the filter position. This greatly increases the difficulty of installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable stainless steel filter, comprising a filter, wherein a sealing cover is sealed on the top of the filter, an inlet is connected to the outer wall of the filter near the horizontal center line, an outlet is connected to the outer wall of the filter near the bottom, and two sets of guide strips are symmetrically installed on the outer wall below the horizontal center line of the filter.

[0007] The outer wall of each set of guide strips is respectively connected to a movable side plate. A bearing is fixedly fitted on the other outer wall of each movable side plate. A bracket is fixedly installed in the inner ring on one side of the bearing. The bottom of the inclined end of the bracket is welded to the surface of the ring seat.

[0008] In order to fix the filter between the two movable side plates after the filter height is adjusted, as an adjustable stainless steel filter of this utility model, preferably, two connecting strips are welded between the two movable side plates, and two sliding grooves are symmetrically opened on the outer wall of the movable side plate on the side that is in contact with the filter.

[0009] The chute is slidably installed on the outer wall of the guide strip. The side of the connecting strip facing the outer wall of the filter is in contact with the outer wall of the second positioning strip. The other side of the second positioning strip is welded to the outer wall of the filter. A set of threaded holes are equally spaced on the second positioning strip. The second positioning strip is locked to the bolt on the outlet through the threaded holes.

[0010] In order to fix the bottom of the filter when the distance between the connecting strip and the bottom of the filter is at its maximum, as an adjustable stainless steel filter of this utility model, preferably, a horizontal plate is welded on the surface of the ring seat, and a butt plate is welded to one end of the horizontal plate. The sides of the horizontal plate and the butt plate are L-shaped. A bolt is provided through the butt plate, and the bolt passes through the butt plate and is threadedly connected and locked to the butt hole on the first positioning strip.

[0011] One side of the docking plate is welded to the outer wall of the filter near the bottom, and the docking plate extends beyond the ground level of the filter.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] To allow the inlet to connect to inlets at various heights, the bolts on the two connecting strips can be removed. Two supports are then needed to hold and position the filter. In this position, the filter can be further lifted. As the filter moves upward, it moves the guide strips on both sides, which move along the outer wall of the connecting movable side plate, thus stably adjusting the filter's height. When the inlet height matches the connecting pipe height, stop adjusting and tighten the bolts through the corresponding connecting strip and the second positioning strip. This ensures a smooth connection between the inlet and the connecting pipe, improving the ease of connecting the filter to external pipelines during use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides the following technical solution: an adjustable stainless steel filter, including filter 1, filter 1 is made of 316L stainless steel, a sealing cover 2 is installed on the top of filter 1, a filter frame and a filter element are installed inside filter 1, when in use, the water inlet 3 on filter 1 is connected to the water pipe to be filtered, when sewage enters the interior of filter 1 through water inlet 3 it will be filtered by filter frame and filter element, and the filtered clean water is discharged through water outlet 4.

[0022] A water inlet 3 is connected and installed on the outer wall of filter 1 near the horizontal center line, a water outlet 4 is connected and installed on the outer wall of filter 1 near the bottom, and two sets of guide strips 5 are symmetrically installed on the outer wall of filter 1 below the horizontal center line.

[0023] The outer wall of each set of guide strips 5 is respectively connected to a movable side plate 6. A bearing 7 is fixedly fitted on the other outer wall of each movable side plate 6. A bracket 8 is fixedly installed in the inner ring on one side of the bearing 7. The bottom of the inclined end of the bracket 8 is welded to the surface of the ring seat 9.

[0024] Preferably, two connecting strips 62 are welded between the two movable side plates 6, and two sliding grooves 61 are symmetrically opened on the outer wall of the movable side plate 6 on the side that is in contact with the filter 1.

[0025] The slide 61 is slidably installed on the outer wall of the guide bar 5. The side of the connecting bar 62 facing the outer wall of the filter 1 is in contact with the outer wall of the second positioning bar 12. The other side of the second positioning bar 12 is welded to the outer wall of the filter 1. A set of threaded holes are opened at equal intervals on the second positioning bar 12. The second positioning bar 12 is locked to the bolt on the outlet 4 through the threaded holes.

[0026] In practical use, when the filter 1 moves along the guide bar 5, the guide bar 5 will move along the track of the sliding groove 61 on the corresponding movable side plate 6, so that the filter 1 can maintain a vertical movement trajectory. This prevents the filter 1 from being misplaced to either side during the movement process, ensuring the consistency of the vertical path between the inlet 3 and the external sewage interface, and facilitating subsequent docking.

[0027] Preferably, a horizontal plate 91 is welded to the surface of the ring seat 9, and a mating plate 92 is welded to one end of the horizontal plate 91. The sides of the horizontal plate 91 and the mating plate 92 are L-shaped. A bolt is provided through the mating plate 92. The bolt passes through the mating plate 92 and is threadedly connected and locked to the mating hole on the first positioning strip 11.

[0028] When it is necessary to empty the foreign objects inside the filter 1, the fixed connection between the docking plate 92 and the second positioning strip 12 should be released. Then, pull the filter 1 to one side and rotate it. When the filter 1 is pulled, it will drive the movable side plates 6 on both sides to rotate synchronously. When the movable side plates 6 rotate, they will rotate on the top of the corresponding brackets 8 through the corresponding bearings 7. In this way, the filter 1 can be tilted to one side, so that the foreign objects inside the filter 1 can be cleaned smoothly.

[0029] One side of the mating plate 92 is welded to the outer wall of the filter 1 near the bottom, and the mating plate 92 extends beyond the ground level of the filter 1.

[0030] In practical use, to enable the inlet 3 to connect to inlets at various heights, the operator must first remove the bolts on the two connecting strips 62. During this disassembly process, since the filter 1 is not fixed, it is prone to shaking or tilting. Therefore, two workers must be positioned on either side of the filter 1 to support and position it, ensuring the stability of the entire device during adjustment. After positioning, the workers can simultaneously apply force to smoothly lift the filter 1 upwards.

[0031] As the filter 1 moves upward, the guide bars 5 on both sides move in tandem. During the movement, the guide bars 5 slide along the outer wall of the mating movable side plate 6. This structure effectively limits the horizontal displacement of the filter 1, thereby ensuring its stable adjustment in the vertical direction.

[0032] When the inlet 3 and the connecting pipe are perfectly aligned at the same height, adjustment should be stopped immediately. At this point, a special tool should be used to thread the bolts through the pre-drilled holes in the corresponding connecting strip 62 and the second positioning strip 12, gradually tightening the bolts. After tightening the bolts, the inlet 3 and the connecting pipe will be precisely aligned, forming a stable, sealed connection. In practical use, this structure significantly improves the ease of connecting the filter 1 to external pipes.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
