Description

Technical Field

[0001] The present invention relates to the field of filtering devices, and particularly to an intelligent filtering device. Background Art

[0002] A liquid filter is a device for removing impurities in a liquid, which is widely used in the field of water treatment and industrial production. According to specific usage requirements, the structures of filtering devices vary to some extent, but the principles are the same. The liquid is pressurized and introduced into the device, and the liquid passes through the filter layer and is discharged to obtain the filtered liquid, while the impurities in the liquid are retained on the surface of the filter layer.

[0003] When the filter continuously filters the liquid, impurities continuously accumulate on the surface of the filter layer, which will cause the permeability of the filter layer to continuously decrease, reducing the filtering efficiency. Traditional filters need to clean the filter layer regularly, relying on manual control, and it is difficult to accurately maintain the efficient operation of the filter layer. Summary of the Invention

[0004] The object of the present invention is to solve the following problems existing in the prior art: when the filter continuously filters the liquid, impurities continuously accumulate on the surface of the filter layer, which will cause the permeability of the filter layer to continuously decrease, reducing the filtering efficiency. Traditional filters need to clean the filter layer regularly, relying on manual control, and it is difficult to accurately maintain the efficient operation of the filter layer.

[0005] To solve the problems existing in the prior art, the present invention provides an intelligent filtering device, including a cylindrical shell. An inlet and an outlet are respectively arranged at both ends of the cylindrical shell. One end of the cylindrical shell close to the outlet is sealed with a cover. A partition is fixed inside the cylindrical shell. A through hole is formed on the surface of the partition. A plugging member is arranged on the side of the partition close to the inlet, and a locking component is arranged on the side of the partition close to the outlet. A filter plate is slidably arranged inside the cylindrical shell, and the filter plate is connected to the cover through a spring.

[0006] Preferably, the plugging member includes a plurality of blocking blocks. The blocking blocks are aligned with the through holes. A shaft cylinder is fixed on the surface of the partition. A shaft rod is slidably inserted into the shaft cylinder. The shaft rod is fixedly connected to the blocking block. The shaft rod is connected to the partition through a spring. The filter plate is slidably sleeved outside the shaft cylinder.

[0007] Preferably, the blocking block is in the shape of a right triangle. One vertex angle of the blocking block is inserted into the through hole, so that the blocking block has a guiding effect during movement and can be stably inserted into the through hole.

[0008] Preferably, the locking component includes a contact block. A torsion port is formed on the surface of the shaft cylinder. The contact block is elastically rotated in the torsion port through a torsion spring. One end of the contact block close to the shaft rod is flat. The shaft rod abuts against the flat end of the contact block. The other end of the contact block obliquely penetrates out of the torsion port.

[0009] Preferably, a retaining rod is fixed inside the twisting port, and the retaining rod abuts against the inner surface of the contact block, so that the flat end plane of the contact block contacts the shaft rod.

[0010] Preferably, the cylinder cover is threadedly connected to the cylinder shell. Limiting grooves are provided on the inner walls of the cylinder cover and the cylinder shell. Limiting posts are fixed at the edges of the filter plate, and the limiting posts slide linearly in the limiting grooves.

[0011] Preferably, an end plate is arranged inside the cylinder cover. A spring is connected between the filter plate and the end plate. A stud penetrates through the surface of the cylinder cover in a threaded manner, and the stud is rotationally connected to the end plate.

[0012] Preferably, a push rod slidably penetrates through the center position of the cylinder cover. The push rod is connected to the cylinder cover through a spring. The push rod slidably inserts into the shaft cylinder. Pressing the push rod causes the push rod to insert into the shaft cylinder, and the push rod presses the shaft rod, causing the shaft rod to retract to the edge of the contact block, so that the contact block releashes the shaft rod again, keeping the through port unblocked.

[0013] Compared with the related art, the intelligent filtering device provided by the present invention has the following beneficial effects:

[0014] The present invention uses the contact block to elastically lock the position of the blocking block to keep the through port unblocked. When the impurities accumulated on the surface of the filter plate reach a certain level, the resistance of the filter plate increases and it moves. The filter plate presses the contact block to release the blocking of the through port by the blocking block. At this time, the liquid flow stops, which is convenient for disassembling and cleaning the filter plate, realizing automatic detection of the permeability of the filter plate.

Detailed implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0025] Embodiment 1

[0026] As Figures 1-3 shown, an intelligent filtering device includes a cylindrical shell 1. The left end face of the shell 1 has a liquid inlet 11, and the right end of the side of the shell 1 is provided with a liquid outlet 12;

[0027] The cylinder cover 2 is threadedly connected to the right end of the shell 1 to form a sealed space inside the shell 1, and a circular filter plate 3 is placed inside the shell 1;

[0028] The liquid inlet 11 is connected to a liquid pressurizing device so that the liquid enters the shell 1. After the liquid is filtered by the filter plate 3, it is discharged from the liquid outlet 12, and the impurities in the liquid remain on the surface of the filter plate 3;

[0029] As Figure 3 shown, a partition plate 4 is fixed inside the shell 1. The cross section of the partition plate 4 seals the inner cavity of the shell 1. Through ports 41 are uniformly opened on the surface of the partition plate 4, and the liquid passes through the through ports 41 and then is filtered by the filter plate 3;

[0030] As Figures 3-5 shown, a shaft cylinder 5 is fixed at the center position on the right side of the partition plate 4. The sealing member includes a plurality of plug blocks 42. The plug blocks 42 are axially aligned with the through ports 41. The end of the shaft cylinder 5 is slidably inserted with a shaft rod 6. The plug blocks 42 are fixed at the end of the shaft rod 6. A spring is used to elastically connect the shaft cylinder 5 and the shaft rod 6 so that the plug blocks 42 have a tendency to move towards the through ports 41;

[0031] The locking assembly includes a contact block 7. Torsion ports 71 are symmetrically opened on the surface of the shaft cylinder 5. The contact block 7 is elastically rotated in the torsion ports 71 through a torsion spring. One end of the contact block 7 close to the shaft rod 6 is flat. A stop bar 72 is fixed in the torsion ports 71. The stop bar 72 abuts against the inner surface of the contact block 7 so that the flat end of the contact block 7 is in flat contact with the shaft rod 6, and the other end of the contact block 7 obliquely penetrates out of the torsion ports 71;

[0032] The filter plate 3 is slidably sleeved outside the shaft cylinder 5, and a spring is connected between the filter plate 3 and the cylinder cover 2;

[0033] Under normal conditions, there is a gap between the blocking block 42 and the through port 41, so that the through port 41 is opened, and the liquid passes through the through port 41 and then is filtered by the filter plate 3. As impurities accumulate continuously, the permeability of the filter plate 3 gradually decreases, and the pressure on the filter plate 3 gradually increases. The pressure causes the filter plate 3 to gradually overcome the elastic force and slide towards the cylinder cover 2 until the filter plate 3 presses against the outer end of the contact block 7, causing the contact block 7 to rotate against the elastic force. The flat end of the contact block 7 gradually turns out of the shaft cylinder 5, and the shaft rod 6 loses the resistance, so that the shaft rod 6 slides in the shaft cylinder 5 under the action of the elastic force, causing the blocking block 42 to insert into the through port 41, and the through port 41 is blocked, stopping the liquid filtration;

[0034] At this time, the rotating cylinder cover 2 is separated from the cylinder shell 1, and the filter plate 3 is removed for cleaning;

[0035] The blocking block 42 is in the shape of a right triangle, and one vertex angle of the blocking block 42 is inserted into the through port 41, so that the blocking block 42 has a guiding effect during movement and can stably insert into the through port 41;

[0036] Embodiment 2

[0037] It includes a cylindrical cylinder shell 1. The left end face of the cylinder shell 1 has a liquid inlet 11, and the right end of the side of the cylinder shell 1 is provided with a liquid outlet 12;

[0038] The cylinder cover 2 is threadedly connected to the right end of the cylinder shell 1, so that a closed space is formed inside the cylinder shell 1, and a circular filter plate 3 is placed inside the cylinder shell 1;

[0039] The liquid inlet 11 is connected to a liquid pressurizing device, so that the liquid enters the cylinder shell 1. The liquid is filtered by the filter plate 3 and then discharged from the liquid outlet 12, and the impurities in the liquid remain on the surface of the filter plate 3;

[0040] A partition plate 4 is fixed inside the cylinder shell 1. The cross section of the partition plate 4 seals the inner cavity of the cylinder shell 1. Through ports 41 are evenly opened on the surface of the partition plate 4, and the liquid passes through the through ports 41 and then is filtered by the filter plate 3;

[0041] A shaft cylinder 5 is fixed at the center position on the right side of the partition plate 4. The blocking member includes a plurality of blocking blocks 42. The blocking blocks 42 are axially aligned with the through ports 41. The end of the shaft cylinder 5 is slidably inserted with a shaft rod 6, and the blocking blocks 42 are fixed at the end of the shaft rod 6. A spring is used to elastically connect the shaft cylinder 5 and the shaft rod 6, so that the blocking blocks 42 have a tendency to move towards the through ports 41;

[0042] As Figures 6-7 shown, different from Embodiment 1: Limiting grooves 32 are provided on the inner walls of the cylinder cover 2 and the cylinder shell 1, and limiting posts 31 are fixedly installed on the edge of the filter plate 3. The limiting posts 31 slide linearly in the limiting grooves 32, and the length of the limiting groove 32 at the position of the cylinder cover 2 is greater than the length of the limiting posts 31;

[0043] During normal liquid filtration, with the limiting post 31 in a clamped state, the torsion lock pins of the cylinder cover 2 and the cylinder shell 1 cannot be opened. When the filter plate 3 is blocked and moves, the limiting post 31 is completely inserted into the limiting groove 32 on the inner wall of the cylinder cover 2, releasing the torsion limitation on the cylinder cover 2 and the cylinder shell 1, for rotating and opening the cylinder cover 2 to clean the filter plate 3.

[0044] An end plate 9 is provided inside the cylinder cover 2, and a spring is connected between the filter plate 3 and the end plate 9. Two groups of stud bolts 91 penetrate through the surface of the cylinder cover 2 in a threaded manner, and the stud bolts 91 are rotatably connected to the end plate 9;

[0045] By rotating the stud bolts 91, the position of the end plate 9 is adjusted, changing the pressure of the spring on the filter plate 3, for adjusting the permeability effect when the filter plate 3 needs to be cleaned.

[0046] A push rod 8 slides through the center position of the cylinder cover 2. The push rod 8 is connected to the cylinder cover 2 through a spring. The push rod 8 slides and inserts into the inside of the shaft cylinder 5. After cleaning the filter plate 3, the filter plate 3 is reinstalled into the cylinder shell 1, the cylinder cover 2 is rotatably installed, and then the push rod 8 is pressed so that the push rod 8 inserts into the shaft cylinder 5. The push rod 8 squeezes the shaft rod 6, causing the shaft rod 6 to retract to the edge of the contact block 7, enabling the contact block 7 to re-clamp the shaft rod 6 and keeping the through port 41 unobstructed.
