Description

Technical Field

[0001] This utility model relates to the field of filter element technology, and in particular to a high temperature and high pressure differential filter element. Background Technology

[0002] The filter element is an important component of the filter and its core part. The filter element can filter impurities and particulate matter in the fluid. Filter elements are made of different materials and structures, such as mesh, fiber, and porous ceramic materials, which can intercept impurities of different sizes. During use, due to the high flow rate and high temperature of the fluid, the filter element is subjected to great impact pressure and high temperature heating. In order to improve the safety of filter element use, it is necessary to provide filter elements that can withstand high temperature and high pressure.

[0003] A search revealed Chinese patent CN214582751U, which discloses a high-temperature, high-pressure differential filter core. This filter core comprises a gasket, a core transition section, a core plate, and a core end, sequentially welded together. The large-diameter end of the core transition section connects to the gasket, and the small-diameter end connects to the core plate. The core plate has through holes arranged in a rectangular array as filter pores. The filter core is directly installed inside the straight pipe section at the heat exchanger inlet via the gasket and flange. This invention overcomes the problem of existing PCHE heat exchangers' filters being prone to breakage and failing to meet filtration requirements. This invention uses 4-6mm stainless steel plates, sufficient to meet the strength requirements caused by the pressure difference across the filter. Chemical etching technology is used to etch 0.3mm microchannels into the steel plate, sufficient to meet filtration needs. Furthermore, the filter uses a flange connection, allowing direct installation inside the straight pipe section at the heat exchanger inlet, facilitating disassembly and replacement.

[0004] The aforementioned comparative documents only allow for convenient replacement of the entire core, but do not enable quick replacement and installation of the filter layer inside the core. Overall replacement can easily lead to high replacement costs, which is not conducive to fully saving on usage costs, nor is it conducive to improving the efficiency of filter layer disassembly and assembly, or the limiting effect on the filter layer. Utility Model Content

[0005] In view of the existing patents, which only allow for easy replacement of the entire core but not for quick replacement and installation of the filter layer inside the core, and which result in high replacement costs due to overall replacement, this invention provides a high-temperature and high-pressure differential filter core.

[0006] The technical solution adopted in this utility model is: a high-temperature, high-pressure differential filter core, comprising:

[0007] Core outer filter cartridge;

[0008] A detachable limiting component is installed on the outer filter cartridge of the core body. The detachable limiting component is used to facilitate the assembly and disassembly of the core body. The detachable limiting component includes a symmetrically installed limiting cap and a frame. The limiting cap is sleeved on the end of the outer filter cartridge of the core body. The frame passes through the interior of the outer filter cartridge of the core body. A retaining plate is fixedly installed on the frame. A retaining groove is opened on the limiting cap. The retaining plate passes through the retaining groove.

[0009] Furthermore, a filter layer is inserted inside the outer filter cartridge of the core, and the filter layer is sleeved on the outside of the skeleton.

[0010] Furthermore, a collar is fitted around the outer surface of the outer filter cartridge of the core.

[0011] Furthermore, a pull rod is fixedly installed on the collar, and the pull rod is fixedly connected to the limiting sleeve cover.

[0012] Furthermore, a sealing gasket is installed between the limiting cylinder cover and the outer filter cylinder of the core, the frame and the filter layer.

[0013] Furthermore, the filter layer is made of high-temperature resistant glass fiber filter cotton.

[0014] The beneficial effects of this utility model are:

[0015] This invention, through the design of a detachable limiting component, enables the rapid replacement and installation of the filter layer inside the core, improving replacement efficiency, reducing time costs, and enhancing the limiting effect on the filter layer.

[0024] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0025] To address the problems existing in the background technology, this application proposes the following technical solution: a high-temperature and high-pressure differential filter core.

[0026] The specific technical solution includes an outer filter cartridge 1 and a detachable limiting component 2;

[0027] like Figure 1-4 As shown, the detachable limiting component 2 is installed on the outer filter cartridge 1 of the core body. The detachable limiting component 2 is used to facilitate the disassembly and assembly of the core body. The detachable limiting component 2 includes a symmetrically installed limiting cap 201 and a frame 202. The limiting cap 201 can cover the end of the outer filter cartridge 1 of the core body. The frame 202 can support the filter layer 4 inside the outer filter cartridge 1 of the core body and prevent the filter layer 4 from being folded by high pressure impact. The limiting cap 201 is sleeved on the end of the outer filter cartridge 1 of the core body. The frame 202 passes through the inside of the outer filter cartridge 1 of the core body. A retaining plate 203 is fixedly installed on the frame 202. The retaining plate 203 can be connected with the retaining groove 3. The retaining cap 201 has a retaining groove 3. The retaining groove 3 can fix the retaining plate 203. The retaining plate 203 passes through the retaining groove 3.

[0028] By pressing the retaining plate 203 at one end of the frame 202, the two retaining plates 203 in the slot 3 are tilted towards the middle of the slot 3. Then, by pulling the limiting cap 201 on the side of the pressed retaining plate 203 away from the outer filter cartridge 201, the pulled limiting cap 201 can move the slot 3 connected to it, and the retaining plate 203 at one end of the frame 202 is pulled out of the slot 3. Then, by pulling the outer filter cartridge 1, the outer filter cartridge 1 can be pulled out from the outside of the frame 202, and the frame 202 can be separated from the inside of the outer filter cartridge 1. The filter layer 4 between the frame 202 and the outer filter cartridge 1 can be replaced. The new filter layer 4 is taken out and fitted onto the outside of the frame 202, and then the frame 202 with the new filter layer 4 is inserted into the outer filter cartridge 202. Inside the outer filter cartridge 1, by aligning the slot 3 on the disassembled limiting sleeve cover 1 with the clamping plate 203 on the frame 202, and by pressing the frame 202 and the limiting sleeve cover 201, the limiting sleeve cover 201 can drive the slot 3 to squeeze the clamping plate 203, and the clamping plate 203 can be inserted into the slot 3. The clamping plate 203 is fixed with the slot 3, which can fix the frame 202 and the limiting sleeve cover 201, enabling the filter layer 4 to be installed quickly. The limiting sleeve covers 201 on both sides are installed at both ends of the outer filter cartridge 1. The limiting sleeve covers 201 on both sides are fixed with the clamping plate 203 through the slot 3. The clamping plate 203 then drives the limiting sleeve cover 201 to be fixed with the frame 202 through the slot 3, which can fix the limiting sleeve cover 201 at both ends of the outer filter cartridge 1.

[0029] like Figure 1 and Figure 3 As shown, a filter layer 4 is installed inside the outer filter cartridge 1 of the core. The filter layer 4 can fully filter impurities in the fluid. The filter layer 4 is sleeved on the outside of the frame 202. The material used for the filter layer 4 is high-temperature resistant glass fiber filter cotton.

[0030] High-temperature resistant glass fiber filter cotton is made of continuous monofilament glass fibers laminated in a non-woven manner, which solves the problem of fiber shedding of ordinary short glass fibers. It also has the advantages of high dust holding capacity, low initial resistance, continuous high temperature resistance below 300℃ without aging, shrinkage, and melting when burned. When used inside the filter core, it can significantly improve the high temperature and high pressure resistance of the core, which can help extend the service life of the core and improve the safety of the core.

[0031] like Figure 3-4 As shown, a collar 5 is provided on the outside of the outer filter cartridge 1 of the core. The collar 5 can be fitted onto the outside of the outer filter cartridge 1 of the core, which can bind the outside of the outer filter cartridge 1 of the core, which is beneficial to improving the stability and pressure resistance of the outer filter cartridge 1 of the core.

[0032] like Figure 3As shown, a pull rod 6 is fixedly installed on the collar 5. The pull rod 6 can drive the connection between the limiting sleeve cover 201 and the collar 5. The pull rod 6 is fixedly connected to the limiting sleeve cover 201. When the limiting sleeve cover 201 is removed, the pull rod 6 is moved by pulling the limiting sleeve cover 201. The pull rod 6 can drive the collar 5 to move, and the collar 5 can be pulled out of the outer filter cartridge 1 of the core body, so that the collar 5 can be disassembled. When the limiting sleeve cover 201 is installed, the collar 5 is placed on the outer filter cartridge 1 of the core body, and then the limiting sleeve cover 201 is installed on one side of the outer filter cartridge 1 of the core body. After the limiting sleeve cover 201 is fixed, the limiting sleeve cover 201 can fix the collar 5 through the pull rod 6, which can improve the efficiency of disassembly and assembly of the structure on the core body.

[0033] like Figure 1-2 As shown, a sealing gasket 7 is installed between the limiting cap 201 and the outer filter cartridge 1, frame 202 and filter layer 4. The sealing gasket 7 can improve the sealing performance between the limiting cap 201 and the outer filter cartridge 1, frame 202 and filter layer 4, and can effectively prevent dust and impurities from entering the space from between the limiting cap 201 and the outer filter cartridge 1, frame 202 and filter layer 4. This is beneficial for fully filtering dust and impurities in the fluid and prevents a large amount of dust and impurities from floating in the space and being inhaled by the human body, thus harming human health.
