Description

Technical Field

[0001] This invention belongs to the field of sintered plate filter element technology, and relates to a sintered plate filter element that is easy to install and disassemble. Background Technology

[0002] Sintered plate filter elements are high-performance filter components made from various polymer composite powders and special binders. They are formed into filter plates with a rigid corrugated porous structure through casting and sintering processes. With their excellent filtration performance and wide range of applications, sintered plate filter elements have become indispensable filter elements in modern industrial production.

[0003] During use, sintered plate filter elements gradually accumulate impurities, particulate matter, and contaminants over time, leading to a decline in filtration efficiency. These contaminants clog the pores of the filter element, reducing its permeability and thus affecting filtration effectiveness. To maintain the equipment's filtration performance, sintered plate filter elements need to be replaced regularly. Traditional fixing methods use bolts, which are cumbersome to disassemble and install.

[0004] To address the above problems, this invention proposes a sintered plate filter element that is easy to install and disassemble. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a sintered plate filter element that is easy to install and disassemble.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A sintered plate filter element that is easy to install and disassemble includes a housing, a support frame supporting the filter element body, and a limiting assembly. The support frame includes a fixed frame and a support plate. The fixed frame is fixedly installed inside the housing, and the support plate is fixedly installed inside the fixed frame. The limiting assembly includes a push rod, which is rotatably mounted on the support plate via a rotating shaft. A torsion spring is fixedly connected to the push rod and the rotating shaft, and the torsion spring is sleeved on the support plate. A connecting plate is fixedly connected to the lower end of the filter element body. A limiting groove that mates with the push rod is provided on the connecting plate. One end of the limiting groove has an outlet, and the limiting groove has a guide part that allows the push rod to rotate. Two inclined blocks are fixedly installed inside the limiting groove. The two inclined blocks are symmetrically arranged inside the limiting groove, and the thicker ends of the two inclined blocks are far apart from each other.

[0008] During installation, move the filter element body along the support plate towards the top rod, so that one end of the top rod abuts against the guide. As the filter element body moves, the top rod gradually moves into the limiting groove. Under the action of the guide, the top rod overcomes the elastic force of the torsion spring and rotates. Then, under the action of the torsion spring, the top rod returns to its original rotation. At the same time, under the action of the inclined block, the filter element body gradually moves upward. During disassembly, press down on the filter element body, the top rod rotates around the pivot, and then pull the filter element body outward.

[0009] Furthermore, a fixing plate is fixedly installed inside the housing, which divides the housing into a lower filter chamber and an upper outflow chamber; the filter element body is installed inside the filter chamber, and a strip-shaped hole is formed on the fixing plate; an air outlet chamber is formed on the filter element body, with an opening at the upper end of the air outlet chamber, and the strip-shaped hole is opposite to the opening of the air outlet chamber, and the upper end of the filter element body is in sealed contact with the fixing plate; gas enters the filter chamber, is filtered by the filter chamber, enters the air outlet chamber, and then flows into the outflow chamber through the strip-shaped hole;

[0010] An exhaust pipe is installed on the casing, and the exhaust pipe is connected to the outflow chamber.

[0011] Furthermore, the guide section includes a vertical section and an inclined section. The vertical section is perpendicular to the length direction of the connecting plate; the inclined section is inclined outward at the end near the outlet of the corresponding limiting groove; the ends of the vertical section and the inclined section away from the outlet are connected.

[0012] Furthermore, the limiting groove has a first limiting part and a second limiting part, the first limiting part and the second limiting part are parallel to each other, and the first limiting part and the second limiting part are located on both sides of the limiting groove; the thicker end of one of the inclined blocks contacts the first limiting part, and the thicker end of the other inclined block contacts the second limiting part.

[0013] Furthermore, the support plate has two plates arranged in parallel, and the limiting component includes two push rods, which are respectively disposed on the two support plates; the connecting plate has two limiting grooves, which correspond one-to-one with the two push rods in the same limiting component, and the limiting grooves cooperate with the corresponding push rods.

[0014] Furthermore, the cross-section of the support plate is trapezoidal.

[0015] Furthermore, the upper end of the top rod has an outwardly convex arc surface.

[0016] Furthermore, an annular rubber pad is provided at the upper end of the filter element body.

[0017] Furthermore, an air conveying plate is fixedly installed inside the box, and the air conveying plate is located above the fixed plate; a flow groove is opened on the air conveying plate; a cavity is opened on the air conveying plate, and air holes are opened on the side wall of the cavity, with the air holes facing the upper end of the filter element body.

[0018] An air tank is installed on the air supply plate, and an air inlet pipe connected to the input end of the air tank is installed on the box body. The air inlet pipe is connected to an air pump; the output end of the air tank is connected to the cavity.

[0019] The lower end of the housing is equipped with a dust hopper that communicates with the filter chamber. The dust hopper is detachably connected to a dust collection bucket. An air outlet is provided on the dust collection bucket, and a filter screen and a control valve are installed inside the air outlet.

[0020] Compared with existing technologies, this invention has the following advantages: When installing the filter element body, the filter element body moves along the support plate, and the push rod gradually enters the limiting groove. Simultaneously, under the action of the guide part, the push rod rotates. Once inside the limiting groove, the push rod returns to its original position under the action of the torsion spring, and finally engages with the limiting groove, fixing the filter element body to the support plate. For disassembly, simply press down on the filter element body and then pull it outwards. The installation and disassembly of the filter element body are simple and convenient, improving the efficiency of installation and disassembly.

[0021] As the filter element body moves upward along the inclined block, it presses against the fixing plate through the annular rubber pad, thereby increasing the sealing performance between the filter element body and the fixing plate.

[0022] Air is blown into the air outlet chamber of the filter body through the air chamber, and then the air in the air outlet chamber flows out through the filter body, which can clean the filter body. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-10 As shown, the technical solution adopted by the present invention is as follows: a sintered plate filter element that is easy to install and disassemble includes a housing 1, a support frame that supports the filter element body 17, and a limiting component.

[0036] A fixing plate 11 is fixedly installed inside the housing 1, dividing the housing 1 into a filter chamber and an outlet chamber. The filter chamber is located below the fixing plate 11, and the outlet chamber is located above the fixing plate 11. An inlet pipe is installed on the side wall of the filter chamber, through which the gas to be filtered enters the filter chamber. An exhaust pipe 5 is installed on the housing 1. The exhaust pipe 5 communicates with the outlet chamber. An exhaust fan is installed inside the exhaust pipe 5 to facilitate the discharge of air from the outlet chamber.

[0037] Multiple filter element bodies 17 are installed inside the filter chamber, and the lower end of the filter element body 17 is detachably mounted on the support frame.

[0038] The filter element body 17 has an air outlet chamber with an opening at its upper end. The fixing plate 11 has multiple parallel strip-shaped holes 12. Each strip-shaped hole 12 corresponds to one filter element body 17. The upper end of the filter element body 17 is sealed against the fixing plate 11, and the opening end of the filter element body 17 communicates with the corresponding strip-shaped hole 12. An annular rubber gasket 21 is provided at the upper end of the filter element body 17 to increase the sealing between the filter element body 17 and the fixing plate 11. When gas enters the filtration chamber, it is filtered by the filter element body 17 and then enters the air outlet chamber of the filter element body 17. It then passes through the opening end of the filter element body 17 and the corresponding strip-shaped hole 12 into the outflow chamber, and is discharged through the exhaust pipe 5.

[0039] The support frame includes a fixed frame 13 and a support plate 14. The fixed frame 13 is fixedly connected to the housing 1. The support plate 14 is fixedly installed inside the fixed frame 13. There are multiple support plates 14, which are parallel to each other. The cross-section of the support plate 14 is trapezoidal, which helps to reduce the accumulation of impurities and facilitates the falling of impurities. In this embodiment, there are two support plates 14. Multiple limiting components are installed at intervals on the support frame. Each limiting component includes two push rods 16, which correspond one-to-one with the two support plates 14. Each push rod 16 is rotatably installed on the corresponding support plate 14 through a rotating shaft 15. A torsion spring is sleeved on the rotating shaft 15, and the torsion spring is fixedly connected between the support plate 14 and the push rod 16. Initially, under the action of the torsion spring, the push rod 16 is inclined relative to the length direction of the support plate 14. In this embodiment, the two push rods 16 in the same limiting component are in a V-shape.

[0040] Each filter element body 17 has a connecting plate 18 fixedly connected to its lower end. Two limiting grooves 19 are formed at the lower end of the connecting plate 18, each corresponding to one of the two push rods 16 in the same limiting assembly. The limiting grooves 19 and push rods 16 are designed to engage, allowing the connecting plate 18 to be fixed to the support plate 14 by engaging the push rods 16 within the limiting grooves 19. In this embodiment, the two limiting grooves 19 on the connecting plate 18 are symmetrically arranged.

[0041] like Figure 8 As shown, the limiting groove 19 is an irregularly shaped groove with an outlet at one end. The limiting groove 19 has a guide portion 1901, which includes a vertical section and an inclined section connected to the vertical section. The vertical section is perpendicular to the length direction of the connecting plate 18, and the inclined section is inclined outward at the end near the outlet of the corresponding limiting groove 19. The ends of the vertical section and the inclined section away from the outlet are connected.

[0042] The limiting groove 19 has a first limiting part 1902 and a second limiting part 1903. The first limiting part 1902 and the second limiting part 1903 are parallel to each other and are respectively disposed on both sides of the limiting groove 19. Two inclined blocks 20 are fixedly installed in the limiting groove 19. The two inclined blocks 20 are symmetrically arranged in the limiting groove 19. The thicker end of one inclined block 20 contacts the first limiting part 1902, and the thicker end of the other inclined block 20 contacts the second limiting part 1903.

[0043] When one end of the push rod 16 enters the limiting groove 19, it abuts against the inclined section of the guide 1901 and moves along the guide 1901 into the limiting groove 19. Under the action of the guide 1901, the push rod 16 rotates around the pivot 15. Then, the push rod 16 moves along the vertical section into the limiting groove 19 until it can return to its original position under the action of the torsion spring. One end of the push rod 16 abuts against the first limiting part 1902, and the other end abuts against the second limiting part 1903. At the same time, under the guidance of the inclined block 20, the connecting plate 18 gradually moves upward, causing the filter element body 17 to squeeze the annular rubber pad 21 and abut against the fixing plate 11. The air outlet chamber of the filter element body 17 is connected to the corresponding strip hole 12.

[0044] The upper end of the push rod 16 is a convex arc surface, which can reduce the friction between the push rod 16 and the inclined block 20.

[0045] A sealed door 2 is installed on one side of the housing 1, and a latch 4 is installed on the housing 1. The latch 4 cooperates with the sealed door 2 to fix the sealed door 2. The sealed door 2 can be opened to install or remove the filter element body 17.

[0046] An air supply plate 10 is fixedly installed inside the housing 1, positioned above a fixed plate 11. An air tank 9 is fixedly installed on the air supply plate 10. An inspection door 3 is provided on the housing 1, allowing convenient inspection or maintenance of the air tank 9. An air inlet pipe 8 is installed on the housing 1, with its outward-facing end connected to an air pump. The inward-facing end of the air inlet pipe 8 is connected to the input end of the air tank 9. The air pump delivers air into the air tank 9 through the air inlet pipe 8.

[0047] Multiple flow channels 102 are provided on the gas conveying plate 10.

[0048] The air delivery plate 10 has multiple cavities, each corresponding to a filter element body 17. Each cavity has multiple air outlets 101 on its side wall, with the outlets 101 facing the upper end of the corresponding filter element body 17. Each cavity is connected to the output end of the air reservoir 9. Air from the air reservoir 9 enters the cavity and is blown into the air outlet chamber of the filter element body 17 through the air outlets 101. The air in the air outlet chamber flows outward through the filter element body 17, cleaning the impurities and contaminants adsorbed on it.

[0049] The lower end of the filter chamber is connected to a dust hopper 6, with the tip of the dust hopper 6 pointing downwards. A dust collection bin 7 is detachably installed at the lower end of the dust hopper 6. An air outlet is provided on the dust collection bin 7, and a filter screen is installed inside the air outlet to prevent impurities and pollutants in the dust collection bin 7 from flowing out. A control valve is also installed on the air outlet. When cleaning the filter element body 17, the control valve is opened.

[0050] Working principle: Initially, under the action of the torsion spring, the push rod 16 is tilted relative to the length direction of the support plate 14. The control valve is in the closed state.

[0051] When installing the filter element body 17, open the sealed box door 2 and install the filter element body 17 on one of the limiting components, so that the top rod 16 in the limiting component is engaged in the corresponding limiting groove 19, thereby fixing the filter element body 17 on the support plate 14.

[0052] Specifically, the filter element body 17 is vertically placed onto the two support plates 14 inside the housing 1, with the connecting plate 18 positioned on one side of the corresponding limiting component. The connecting plate 18 is then pressed against the fixed frame 13, at which point one end of the push rod 16 is opposite the inclined section of the limiting groove 19 and the guide portion 1901. The filter element body 17 is then pushed, causing it to slide along the support plate 14 towards the corresponding limiting component until the push rod 16 contacts the inclined section of the guide portion 1901. Subsequently, as the filter element body 17 moves, the push rod 16 gradually enters the limiting groove 19 along the inclined section of the guide portion 1901. Under the action of the inclined section of the guide portion 1901, the push rod 16 gradually rotates until it is parallel to the length direction of the support plate 14. Then continue pushing the filter body 17, the push rod 16 moves along the vertical section of the guide 1901 into the limiting groove 19 until the push rod 16 is released from the limiting effect of the vertical section of the guide 1901. After the push rod 16 is no longer restricted, it returns to its original position and rotates under the action of the torsion spring until the push rod 16 abuts against the first limiting part 1902 and the second limiting part 1903.

[0053] At the same time, when the push rod 16 is reset and rotated in the limiting groove 19, under the guidance of the inclined block 20, the filter element body 17 gradually rises, and then the filter element body 17 squeezes the annular rubber pad 21, and the upper end of the filter element body 17 is in sealed contact with the fixing plate 11.

[0054] In use, the gas to be filtered enters the filter chamber through the inlet pipe. After being filtered by the filter element body 17, the gas in the filter chamber enters the outlet chamber of the filter element body 17, then enters the space between the air conveying plate 10 and the fixed plate 11, and flows out through the flow groove 102 and the exhaust pipe 5.

[0055] After a period of use, the filter body 17 will accumulate impurities and contaminants, and the filter body 17 needs to be cleaned in a timely manner to ensure the filtration effect.

[0056] During cleaning, the control valve is opened and the air pump connected to the air inlet pipe 8 is started. The air pump delivers air through the air inlet pipe 8 to the air tank 9. The air tank 9 delivers air to the cavity of the air conveying plate 10. Then, the air in the cavity is blown into the air outlet cavity of the filter element body 17 through the air outlet hole 101. When the air in the air outlet cavity flows out through the side wall of the air outlet cavity, it cleans the filter element body 17. The cleaned impurities and pollutants fall into the dust collection bin 7 through the ash hopper 6.

[0057] When the filter element body 17 needs to be disassembled for maintenance or replacement, press the filter element body 17 downwards. The connecting plate 18 will press the push rod 16 downwards, and the push rod 16 will slide downwards along the inclined block 20 while rotating around the rotating shaft 15 until the push rod 16 is parallel to the length direction of the support plate 14. Then pull the filter element body 17 outwards until the push rod 16 disengages from the limiting groove 19, and then the filter element body 17 can be removed. After the push rod 16 disengages from the limiting groove 19, it returns to its initial state under the action of the torsion spring.

[0058] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
