Description

Technical Field

[0001] This utility model relates to the field of elastic pressure ring assembly technology, and in particular to an elastic pressure ring assembly for the sealing flange of a flat-cover single-bag filter. Background Technology

[0002] Flat-cover single-bag filters are a common type of industrial filtration equipment, mainly used for filtering liquids or gases to remove impurities, particles, or suspended solids to meet production process or usage requirements. They use internal filter bags (made of materials such as polypropylene, nylon, or polyester) to trap solid particles, suspended solids, colloids, and other impurities in the fluid, ensuring the filtered fluid reaches the required cleanliness. The elastic pressure ring assembly on the sealing flange is used to ensure the filter remains sealed during the filtration process.

[0003] In the use of elastic pressure ring assemblies for sealing flanges of common flat-cover single-bag filters, the sealing ring inside the assembly is typically made of a high-elasticity material to ensure sealing performance after installation. However, a high-elasticity sealing ring has a larger diameter when not inserted into the groove. When inserted into a smaller groove, it is prone to shifting or falling out after a period of use, affecting the sealing effect. Utility Model Content

[0004] In view of this, the present invention provides an elastic pressure ring assembly for the sealing flange of a flat-cover single-bag filter. The main technical problem to be solved is that the sealing ring is prone to misalignment or falling out, which affects the sealing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an elastic pressure ring assembly for the sealing flange of a flat-cover single-bag filter, comprising a main body, the main body including a shell, a first groove formed on the upper surface of the shell, a sealing mechanism installed on the inner wall of the first groove, the sealing mechanism including a first protrusion, the surface of the first protrusion being fixedly connected to the inner wall of the first groove, a second rotating shaft being movably connected to the surface of the first protrusion, a rotating rod being fixedly connected to the surface of the second rotating shaft, a fourth groove formed on the surface of the rotating rod, a limiting mechanism installed on the surface of the shell, the limiting mechanism including a connector, a first guide rod being fixedly connected to the surface of the connector, the end of the first guide rod extending into the interior of the fourth groove, and a piston being fixedly connected to the surface of the first guide rod.

[0006] By adopting the above technical solution, the rotating rod is turned upwards, and then the third groove is inserted after it corresponds to the position of the rotating rod. The protrusion is then inserted into the inner wall of the first groove, and the connector installed on the surface of the outer shell is pressed to insert the first guide rod into the fourth groove, thereby limiting the angle of the rotating rod and preventing it from continuing to rotate.

[0007] As a further description of the above technical solution:

[0008] A sealing ring is installed on the inner wall of the first groove, and a third groove is formed on the surface of the sealing ring. The inner wall of the third groove is in contact with the surface of the first protrusion.

[0009] By adopting the above technical solution, the first protrusion and the inner wall of the first groove are tightly fitted to ensure that no air leaks in at the connection and to ensure the sealing of the device.

[0010] As a further description of the above technical solution:

[0011] The outer casing has a first through hole on its surface and a second groove inside the first through hole. The surface of the first guide rod is in contact with the inner wall of the first through hole, and the surface of the piston is in contact with the inner wall of the second groove.

[0012] By adopting the above technical solution, the piston fixed on the surface of the first guide rod has a large frictional force, and the first guide rod will only move when the connector is pushed or pulled.

[0013] As a further description of the above technical solution:

[0014] A connecting plate is fixedly connected to the surface of the outer shell, a first rotating shaft is fixedly connected to the surface of the connecting plate, a rotating mechanism is movably connected to the surface of the first rotating shaft, and the rotating mechanism includes a second connecting block, the surface of the second connecting block being movably connected to the surface of the first rotating shaft.

[0015] By adopting the above technical solution, the second connecting block rotates around the first rotating shaft on the connecting plate.

[0016] As a further description of the above technical solution:

[0017] A second protrusion is fixedly connected to the upper surface of the second connecting block, a slider is fixedly connected to the surface of the second protrusion, a first connecting block is installed on the upper surface of the second protrusion, a fifth groove is formed on the inner wall of the first connecting block, a sliding groove is formed on the inner wall of the fifth groove, and the slider is located inside the sliding groove.

[0018] By adopting the above technical solution, the second protrusion is slidably connected to the inside of the first connecting block by a slider, so that the first connecting block can move a certain distance relative to the second connecting block.

[0019] As a further description of the above technical solution:

[0020] A rotating cover is fixedly connected to the surface of the first connecting block, and a handle is fixedly connected to the upper surface of the rotating cover. A sixth groove is formed on the upper surface of the rotating cover, and the sixth groove is located to the left of the handle.

[0021] By adopting the above technical solution, the handle makes it easier to apply force to the rotating cover to open and close it.

[0022] As a further description of the above technical solution:

[0023] A fixing mechanism is installed on the upper surface of the housing. The fixing mechanism includes a second guide rod. The bottom of the second guide rod is fixedly connected to the upper surface of the housing, and a bolt is threaded onto the surface of the second guide rod.

[0024] By adopting the above technical solution, tightening the bolts on the surface of the second guide rod can strengthen the connection between the rotating cover and the outer shell, thereby improving the sealing performance.

[0025] As a further description of the above technical solution:

[0026] The rotating cover has a second through hole on its surface, the second guide rod is located inside the second through hole, and the lower surface of the bolt is in contact with the inner wall of the sixth groove.

[0027] By adopting the above technical solution, when it is necessary to quickly open the rotating cover, first turn the bolt a few turns so that the lower half of the bolt is disengaged from the sixth groove, and then push the rotating cover towards the connecting plate. The first connecting block and the second connecting block slide relative to each other. At this time, the rotating cover can directly rotate around the first rotating shaft to open the rotating cover.

[0028] By employing the above technical solution, the elastic pressure ring assembly for the sealing flange of the flat-cover single-bag filter of this utility model has at least the following beneficial effects:

[0029] 1. Compared with the prior art, this type of flat-cover single-bag filter uses an elastic pressure ring assembly for its sealing flange. Through a rotating rod, a connector, and a first guide rod, during use, the rotating rod inside the first groove is turned upwards. Then, the third groove on the sealing ring aligns with the position of the rotating rod and is inserted. Next, the protrusion is inserted into the inner wall of the first groove. At this time, the angle of the rotating rod rotates to be parallel to the upper surface of the outer shell. Pressing the connector mounted on the outer shell surface causes the first guide rod, fixed on the surface of the connector, to insert into the fourth groove on the surface of the rotating rod, limiting the angle of the rotating rod and preventing further rotation. The first guide rod is fixed on the surface of the first guide rod... The piston has a large frictional force, and the first guide rod will only move when the connector is pushed or pulled. Compared with conventional devices, the sealing ring inside the elastic pressure ring assembly of the filter's sealing flange is usually made of a sealing ring with better elasticity after it is installed inside the sealing mechanism to ensure sealing performance. However, the sealing ring with better elasticity has a larger diameter when it is not inserted into the groove. If it is inserted into a smaller groove, the sealing ring is prone to deviation or falling out after a period of use, affecting the sealing effect. This device can firmly fix the sealing ring inside the sealing mechanism during use, thus improving the sealing effect of the device.

[0030] 2. Compared with the prior art, the sealing flange of this flat-cover single-bag filter uses an elastic pressure ring assembly. Through bolts, a rotating cover, and a second connecting block, when it is necessary to quickly open the rotating cover, first turn the bolts a few times so that the lower half of the bolts disengage from the sixth groove on the rotating cover. Then push the rotating cover towards the connecting plate. The first connecting block and the second connecting block fixed on the surface of the rotating cover slide relative to each other. At this time, the rotating cover can directly rotate around the first rotating shaft to open the rotating cover. It can quickly open the rotating cover, and the sealing performance can be ensured by using the second guide rod and the bolts for fixation. Attached Figure Description

The first protrusion 303 is then inserted into the inner wall of the first groove 105. The connector 201 installed on the surface of the outer shell 101 is pressed, so that the first guide rod 202 is inserted into the fourth groove 306, limiting the angle of the rotating rod 305 and preventing it from continuing to rotate.

[0041] A sealing ring 301 is installed on the inner wall of the first groove 105. A third groove 302 is formed on the surface of the sealing ring 301. The inner wall of the third groove 302 is in contact with the surface of the first protrusion 303.

The piston 203 fixed on the surface of the first guide rod 202 has a large friction force. Only when the connector 201 is pushed or pulled will the first guide rod 202 be affected. The mechanism moves only after 02. A connecting plate 103 is fixedly connected to the surface of the outer shell 101. A first rotating shaft 104 is fixedly connected to the surface of the connecting plate 103. A rotating mechanism 4 is movably connected to the surface of the first rotating shaft 104.

Rotating cover 401 is fixedly connected to the surface of first connecting block 403, and handle 409 is fixedly connected to the upper surface of rotating cover 401. A sixth groove 410 is opened on the upper surface of rotating cover 401. The sixth groove 410 is located to the left of handle 409. Using handle 409, force can be applied to rotating cover 401 more easily to open and close rotating cover 401. Fixing mechanism 5 is installed on the upper surface of outer shell 101. Fixing mechanism 5 includes second guide rod 501, the bottom of second guide rod 501... The second guide rod 501 is fixedly connected to the upper surface of the outer casing 101. A bolt 502 is threaded onto the surface of the second guide rod 501. Tightening the bolt 502 on the surface of the second guide rod 501 strengthens the connection between the rotating cover 401 and the outer casing 101, improving sealing. A second through hole 402 is provided on the surface of the rotating cover 401. The second guide rod 501 is located inside the second through hole 402. The lower surface of the bolt 502 is in contact with the inner wall of the sixth groove 410. When it is necessary to quickly open the rotating cover 401, first turn the bolt 502 several times to disengage the lower half of the bolt 502 from the sixth groove 410. Then, push the rotating cover 401 towards the connecting plate 103. The first connecting block 403 and the second connecting block 404 slide relative to each other.At this point, the rotating cover 401 can rotate directly around the first rotating shaft 104, thus opening the rotating cover 401.

[0042] Working principle: The rotating rod 305 inside the first groove 105 is turned upwards. Then, the third groove 302 on the sealing ring 301 is aligned with the rotating rod 305 and inserted. Next, the first protrusion 303 is inserted into the inner wall of the first groove 105. At this point, the angle of the rotating rod 305 rotates to be parallel to the upper surface of the outer shell 101. The connector 201 mounted on the surface of the outer shell 101 is pressed, causing the first guide rod 202 fixed on the surface of the connector 201 to insert into the fourth groove 306 on the surface of the rotating rod 305. This limits the angle of the rotating rod 305, preventing further rotation. The piston 203 fixed on the surface of the first guide rod 202 has significant friction. The first guide rod 202 will only move when the connector 201 is pushed or pulled. When it is necessary to quickly open the rotating cover 401, first turn the bolt 502 a few times so that the lower half of the bolt 502 is disengaged from the sixth groove 410 on the rotating cover 401. Then push the rotating cover 401 towards the connecting plate 103. The first connecting block 403 and the second connecting block 404 fixed on the surface of the rotating cover 401 slide relative to each other. At this time, the rotating cover 401 can rotate directly around the first rotating shaft 104 to open the rotating cover 401. The rotating cover 401 can be opened quickly, and the sealing can be ensured by fixing the second guide rod 501 and the bolt 502.
