Description

Technical Field

[0001] This application relates to the field of filter elements, and in particular to a metal powder sintered filter element. Background Technology

[0002] Filter elements are key components in gas filtration systems. Their primary function is to effectively filter particulate impurities from gases through their porous structure. In various industrial and environmental fields, gas filter elements are widely used to filter harmful substances from various gases, such as dust, particulate matter, and other pollutants. Filter elements capture particulate impurities in gases through physical or chemical processes, ensuring that the gas flows smoothly without carrying contaminants.

[0003] As the filter cartridge is used for a longer period of time, a large amount of particulate impurities will gradually accumulate on the inner wall of the filter cartridge body. As the filter cartridge becomes clogged, the resistance of gas passing through the filter cartridge will increase, and the filtration efficiency will also decrease, affecting the filtration effect. Some filter cartridges and separator covers are connected together by threads to ensure the airtightness of the gas flow channel. However, in long-term use, the threaded connection may loosen. If the filter cartridge and separator cover are not firmly connected, unfiltered gas will leak, and in severe cases, contaminants may enter the gas flow system, thereby affecting the overall operating efficiency of the filtration system. Utility Model Content

[0004] This application provides a metal powder sintered filter element. When using the filter element, the particulate impurities accumulated on the inner wall of the filter element are treated, which can improve the filtration effect of the filter element and prevent gas from escaping when the connection is loose.

[0005] To achieve the above objectives, this application adopts the following technical solution: a metal powder sintered filter element, the filter element comprising:

[0006] Filter element body;

[0007] A separation cover is disposed on one side of the filter element body, and a connecting pipe is fixedly disposed at one end of the separation cover;

[0008] A fixing ring is fixedly installed on the inner wall of the connecting pipe, and a transmission rod is installed on the inner wall of the fixing ring via a bearing;

[0009] Multiple first-stage rods are fixedly mounted on the outer surface of the transmission rod, and the inner walls of the multiple first-stage rods are movably fitted with second-stage rods.

[0010] As a further improvement of this application: scrapers are fixedly provided on one side of each of the plurality of second sleeve rods, and springs are fixedly provided on the inner wall of each of the plurality of first sleeve rods.

[0011] As a further improvement of this application: a turbine blade is fixedly provided at one end of the transmission rod.

[0012] As a further improvement of this application: a positioning rod is fixedly provided on the outer surface of the separation cover, and a first elastic plate is movably sleeved on the outer surface of the separation cover.

[0013] As a further improvement of this application: two threaded rods are fixedly provided on one side of the first elastic plate, and a second elastic plate is movably sleeved on the outer surface of the two threaded rods.

[0014] As a further improvement of this application: two through holes are provided on one side of the second elastic plate, and any one of the threaded rods is matched with any other threaded rod.

[0015] As a further improvement of this application: sleeves are threaded onto the outer surfaces of both threaded rods, and the second elastic plate is disposed on the outer surface of the filter element body.

[0016] As a further improvement of this application: a receiving box is threadedly fitted at the bottom of the filter element body.

[0017] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0018] 1. This utility model increases the flow rate of gas passing through the connecting pipe. The high-speed flowing gas generates a pressure difference when passing over the turbine blades, causing the turbine blades to rotate. The fixed ring supports the transmission rod, which can rotate via bearings. The turbine blades then drive the transmission rod to rotate. Multiple second rods can slide on the inner walls of multiple first rods. Multiple springs have elastic force, which pushes the multiple second rods, causing multiple scrapers to adhere tightly to the inner wall of the filter element body. When the transmission rod rotates, it drives the first rods to rotate, which in turn drives the multiple scrapers to rotate. The rotating scrapers scrape away the accumulated particulate impurities inside the filter element body, causing the impurities to fall from the inner wall of the filter element body and into the receiving box. By rotating the receiving box, it can be removed from the bottom of the filter element body to clean the impurities inside. This process treats the accumulated particulate impurities on the inner wall of the filter element during use, improving the filter element's filtration efficiency.

[0019] 2. When using the filter element, the filter element body and the separation cover are connected together by threads. At this time, the positioning rod is sleeved on the outer surface of the positioning rod, and the two threaded rods can slide at the inner walls of the two through holes. Then, the two second elastic plates are inserted into the inside of the two through holes, so that the second elastic plates and the first elastic plates are combined together. Both the first and second elastic plates have elasticity. At this time, by rotating the two sleeves, the first and second elastic plates are tightly fitted at the connection between the filter element body and the separation cover. When the connection between the filter element body and the separation cover is loose, the first and second elastic plates can prevent unfiltered gas from escaping. Therefore, when using the filter element, gas can be prevented from escaping when the connection is loose. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, as Figures 1-5 As shown, this application provides a metal powder sintered filter element, which includes: a filter element body 1; a separation cover 2, disposed on one side of the filter element body 1, and a connecting pipe 201 fixedly disposed at one end of the separation cover 2; a fixing ring 202, fixedly disposed on the inner wall of the connecting pipe 201, and a transmission rod 203 disposed on the inner wall of the fixing ring 202 via a bearing; a plurality of first sleeve rods 205, respectively fixedly disposed on the outer surface of the transmission rod 203, and a second sleeve rod 206 movably embedded in the inner wall of each of the plurality of first sleeve rods 205, a scraper 208 fixedly disposed on one side of each of the plurality of second sleeve rods 206, a spring 207 fixedly disposed on the inner wall of each of the plurality of first sleeve rods 205, a turbine blade 204 fixedly disposed at one end of the transmission rod 203, and a receiving box 209 threadedly disposed at the bottom of the filter element body 1.

[0029] By adopting the above technical solution, the filter element is made of high-temperature resistant and corrosion-resistant metal material. During filtration, the gas to be treated is connected to the gas channel through the connecting pipe 201. The gas enters the interior of the filter element body 1 through the connecting pipe 201. The filter element body 1 filters particulate impurities from the gas through its porous structure. Over time, a large number of particles will accumulate on the inner wall of the filter element body 1, and these particulate impurities will clog the pores of the filter element body 1. By increasing the flow rate of the gas passing through the connecting pipe 201, the high-speed flowing gas generates a pressure difference when it passes over the turbine blades 204, causing the turbine blades 204 to rotate. The fixing ring 202 supports the transmission rod 203, and the transmission rod 203 can rotate through the bearing. In turn, the turbine blades 204 drive the transmission rod 204. 3. The transmission rod 203 rotates, and since multiple second rods 206 can slide on the inner wall of multiple first rods 205 respectively, and multiple springs 207 have elastic force, the elastic force generated by multiple springs 207 pushes multiple second rods 206, thereby making multiple scrapers 208 and the inner wall of the filter element body 1 tightly adhere. When the transmission rod 203 rotates, it drives the first rods 205 to rotate, and further drives multiple scrapers 208 to rotate through multiple second rods 206. The rotating multiple scrapers 208 scrape the particulate impurities accumulated inside the filter element body 1, causing the impurity particles to fall from the inner wall of the filter element body 1 and further fall into the inside of the receiving box 209. By rotating the receiving box 209, the receiving box 209 can be removed from the bottom of the filter element body 1, and the impurities inside the receiving box 209 can be cleaned.

[0030] Example 2, as Figures 1-5As shown, a positioning rod 3 is fixedly installed on the outer surface of the separation cover 2, and a first elastic plate 301 is movably sleeved on the outer surface of the separation cover 2. Two threaded rods 302 are fixedly installed on one side of the first elastic plate 301, and a second elastic plate 303 is movably sleeved on the outer surface of the two threaded rods 302. Two through holes 305 are opened on one side of the second elastic plate 303. Any one threaded rod 302 is matched with any one threaded rod 302. A sleeve 304 is threaded on the outer surface of each of the two threaded rods 302. The second elastic plate 303 is disposed on the outer surface of the filter element body 1.

[0031] By adopting the above technical solution, the filter element body 1 and the separation cover 2 are connected together by threads. At this time, the positioning rod 3 is sleeved on the outer surface of the positioning rod 3, and the two threaded rods 302 can slide at the inner wall of the two through holes 305. Then, the two second elastic plates 303 are inserted into the inside of the two through holes 305, so that the second elastic plates 303 and the first elastic plates 301 are combined together. Both the first elastic plates 301 and the second elastic plates 303 have elasticity. At this time, by rotating the two sleeves 304, the first elastic plates 301 and the second elastic plates 303 are tightly sleeved at the connection between the filter element body 1 and the separation cover 2. When the connection between the filter element body 1 and the separation cover 2 is loose, the first elastic plates 301 and the second elastic plates 303 can prevent unfiltered gas from escaping.

[0032] Working Principle: When using the sintered filter element, the entire filter element is made of high-temperature resistant and corrosion-resistant metal material. During filtration, the gas to be treated is connected through the connecting pipe 201. The gas enters the interior of the filter element body 1 through the connecting pipe 201. The filter element body 1 filters particulate impurities from the gas through its porous structure. Over time, a large number of particles will accumulate on the inner wall of the filter element body 1, clogging the pores. By increasing the flow rate of the gas through the connecting pipe 201, the high-speed flowing gas generates a pressure difference when passing over the turbine blades 204, causing the turbine blades 204 to rotate. The fixed ring 202 supports the transmission rod 203, which can rotate via bearings. The turbine blades 204 then drive the transmission rod 203 to rotate. Since multiple second sleeve rods 206 can slide along the inner walls of multiple first sleeve rods 205, and multiple springs 207 have elastic force, this force pushes the multiple second sleeve rods 206, causing the multiple scrapers 208 to press tightly against the inner wall of the filter element body 1. When the transmission rod 203 rotates, it drives the first sleeve rods 205 to rotate, which in turn drives the multiple scrapers 208 to rotate via the multiple second sleeve rods 206. The scraper 208 scrapes the particulate impurities accumulated inside the filter element body 1, causing the impurities to fall from the inner wall of the filter element body 1 and further into the receiving box 209. By rotating the receiving box 209, it can be removed from the bottom of the filter element body 1 to clean the impurities inside. This process treats the particulate impurities accumulated on the inner wall of the filter element during use, improving the filtration effect. When using the filter element, the filter element body 1 and the separation cover 2 are connected together by threads. At this time, the positioning rod 3 is sleeved on the outer surface of the positioning rod 3, and the two threaded rods 302 can pass through the two through holes 30. 5. Slide along the inner wall and insert the two second elastic plates 303 into the two through holes 305, so that the second elastic plates 303 and the first elastic plate 301 are combined together. Both the first elastic plate 301 and the second elastic plate 303 have elasticity. At this time, by rotating the two sleeves 304, the first elastic plate 301 and the second elastic plate 303 are tightly fitted at the connection between the filter element body 1 and the separation cover 2. When the connection between the filter element body 1 and the separation cover 2 is loose, the first elastic plate 301 and the second elastic plate 303 can prevent unfiltered gas from escaping. Thus, when using the filter element, loose connection can prevent gas from escaping.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
