Description

Technical Field

[0001] The utility model relates to the technical field of gas filtering, in particular to a novel gas pipeline filter element. Background Art

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. However, the gas often contains particles and impurities. If a filter is not used to filter the gas, the residual solids in the gas pipeline will enter the downstream and be retained on the valve sealing disk, causing the valve to seal loosely. Therefore, it is particularly important for filters to filter the gas.

[0003] However, in the prior art, the filter element of the filter is usually an integral whole. During the filtering process, once there are too many impurities on a small area of ​​the filter mesh of the filter element and they cannot be completely cleaned, the entire filter mesh needs to be replaced. However, the filter mesh used to filter gas is usually expensive. When only a small area cannot be cleaned, the entire filter mesh needs to be replaced, which will cause a waste of resources and costs. Utility Model Content

[0004] The utility model mainly provides a segmented filter screen combination and a novel gas pipeline filter element which reduces the cost of replacing the filter screen.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a novel gas pipeline filter element, comprising: two mounting rings, a filtering mechanism is arranged between opposite sides of the two mounting rings;

[0006] The filtering mechanism includes eight fixed plates, four of which are welded with a group of fixing strips on one side of their outer walls, and one side of their outer walls of the four groups of fixing strips are respectively fixedly connected to one side of their outer walls of the other four of the eight fixed plates, the inner surfaces of the eight fixed plates are movably provided with internal mounting frames, four of the eight internal mounting frames are fixedly installed with internal filter screens on one side of their outer walls, and one side of their outer walls of the four internal filter screens are respectively fixedly connected to one side of their outer walls of the other four of the eight internal mounting frames.

[0007] Preferably, a group of internal connecting strips are welded on one side of the outer wall of four of the eight internal installation frames, and one side of the outer wall of the four groups of internal connecting strips are respectively fixedly connected to one side of the outer wall of the other four of the eight internal installation frames, and the inner surface walls of the four groups of internal connecting strips are respectively fixedly connected to the four internal filter screens, so that after the eight internal installation frames are installed with internal filter screens in groups of two, each group of internal installation frames and the internal filter screen can be fixed with the connecting strips to prevent the internal filter screen from being deformed during filtering.

[0008] Preferably, sealing blocks are movably inserted into the inner walls of three of the eight fixed plates, and the inner walls of the three sealing blocks are movably inserted into the inner walls of three of the eight fixed plates, so that the gap between each two adjacent fixed plates can be sealed by the sealing blocks.

[0009] Preferably, sealing rings are fixedly inserted into the inner surface walls of the eight fixed plates, and one side of the outer wall of the eight sealing rings is fixedly connected to one side of the outer wall of eight internal installation frames, respectively, to facilitate sealing of the gap between each fixed plate and the internal installation frame installed therein.

[0010] Preferably, an external filter frame is movably inserted between opposite sides of the two mounting rings, and an external filter screen is fixedly installed on the inner surface wall of the external filter frame to facilitate secondary filtration of the gas and prevent impurities from flowing out of the gas pipeline due to problems with the internal filter screen structure or through gaps.

[0011] Preferably, the mesh number of the external filter is the same as the mesh number of the four internal filter screens, so that the external filter screen and the internal filter screen have the same filtering specifications, further improving the filtering effect.

[0012] Preferably, limiting blocks are fixedly installed at both ends of the outer wall of the external filter frame, limiting grooves are opened between the opposite sides of the two mounting rings, and the inner walls of the two limiting grooves are movably inserted into the outer walls of the two limiting blocks respectively, so as to fix the external filter frame and prevent the external filter frame from falling.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, by setting a filtering mechanism, since the filtering mechanism is composed of a plurality of internal filtering screens, when one or more internal filtering screens in the entire filtering mechanism cannot be cleaned due to excessive impurities, the fixing plate used to fix the internal filtering screen can be directly taken out from the inside of the mounting ring, and the new internal filtering screen and the fixing plate can be replaced, thereby avoiding the problem in the prior art that the entire filtering screen must be replaced when only a small area of ​​the entire filtering screen cannot be cleaned, thereby reducing the waste of resources and costs.

[0015] 2. In the utility model, by providing a sealing ring and a sealing block, it is convenient to seal the gap between the internal filter screen and the fixed plate, and the gap between the fixed plates, thereby ensuring the sealing of the entire filter element. At the same time, an external filter frame and an external filter screen are provided, which can perform secondary filtration on the gas, improve the purity of the gas, and prevent blockage inside the gas pipeline.

[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a novel gas pipeline filter element, comprising: two mounting rings 1, a filtering mechanism 2 is arranged between opposite sides of the two mounting rings 1;

[0024] The filtering mechanism 2 includes eight fixed plates 201, and one side of the outer wall of four of the eight fixed plates 201 is welded with a group of fixing strips 202, and one side of the outer wall of the four groups of fixing strips 202 is fixedly connected to one side of the outer wall of the other four fixed plates 201 of the eight fixed plates 201, and the inner surface walls of the eight fixed plates 201 are movably inserted with internal installation frames 203, and one side of the outer wall of four of the eight internal installation frames 203 is fixedly installed with internal filter screens 204, and one side of the outer wall of the four internal filter screens 204 is fixedly connected to one side of the outer wall of the other four of the eight internal installation frames 203.

[0025] like Figure 4 As shown, a group of internal connecting strips 205 are welded to one side of the outer wall of four of the eight internal installation frames 203, and one side of the outer wall of the four groups of internal connecting strips 205 are respectively fixedly connected to one side of the outer wall of the other four of the eight internal installation frames 203, and the inner surface walls of the four groups of internal connecting strips 205 are respectively fixedly connected to the four internal filter screens 204, so that after the eight internal installation frames 203 are installed with internal filter screens 204 in groups of two, each group of internal installation frames 203 and the internal filter screen 204 can be fixed by using the connecting strips to prevent the internal filter screen 204 from being deformed during filtering.

[0026] like Figure 4 As shown, sealing blocks 206 are movably inserted into the inner walls of three of the eight fixed plates 201, and the inner walls of the three sealing blocks 206 are movably inserted into the inner walls of three of the eight fixed plates 201, respectively, so as to facilitate sealing the gap between each two adjacent fixed plates 201 through the sealing blocks 206.

[0027] like Figure 4 As shown, the inner surface walls of the eight fixed plates 201 are fixedly inserted with sealing rings 207, and the outer wall sides of the eight sealing rings 207 are respectively fixedly connected to the outer wall sides of the eight internal installation frames 203, so as to facilitate sealing the gap between each fixed plate 201 and the internal installation frame 203 installed therein.

[0028] like Figure 3 As shown, an external filter frame 3 is movably inserted between the opposite sides of the two mounting rings 1, and an external filter screen 4 is fixedly installed on the inner surface wall of the external filter frame 3 to facilitate secondary filtration of the gas and prevent impurities from flowing out of the gas pipeline due to problems with the structure of the internal filter screen 204 or through gaps.

[0029] like Figure 3 As shown, the mesh number of the external filter screen 4 is the same as the mesh number of the four internal filter screens 204, so that the external filter screen 4 and the internal filter screens 204 have the same filtering specifications, further improving the filtering effect.

[0030] like Figure 2-3 As shown, limiting blocks 5 are fixedly installed at both ends of the outer wall of the external filter frame 3, limiting grooves 6 are opened between the opposite sides of the two mounting rings 1, and the inner walls of the two limiting grooves 6 are movably inserted into the outer walls of the two limiting blocks 5, respectively, to facilitate fixing the external filter frame 3 and prevent the external filter frame 3 from falling.

[0031] The method of use and working principle of this device: First, the installation method of the filter element is explained. First, the structure formed by the two fixing plates 201 on the internal filter screen 204 is a whole, which is recorded as a filter block. First, multiple filter blocks are connected by bolts and nuts, and the gaps between each filter block are sealed by a sealing block 206. In each filter block, the gap between the fixing plate 201 and the internal mounting frame 203 will be sealed by a sealing ring 207. Then, the multiple filter blocks and the external filter frame 3 are clamped by two mounting rings 1, and the two mounting rings 1 are also connected to the two adjacent filter blocks by bolts and nuts. The installation is completed. After the installation is completed, the filter element is installed in the filter. When gas enters the filter element, most of the impurities will be filtered out by the internal filter 204 first, and then a very small amount of impurities will be filtered out by the external filter 4 to improve the purity of the gas. When filtering for a long time, the impurities on the internal filter 204 will increase, affecting the filtering effect of the internal filter 204. At this time, the entire filter element is disassembled according to the above operation, and the internal filter 204 and the external filter 4 are cleaned. Once it is found that there are too many impurities in a certain internal filter 204 and it cannot be cleaned, the filter block where the internal filter 204 is located can be replaced.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
