Description

Technical Field

[0001] The invention relates to the field of valve filtering, and in particular to an auxiliary valve filtering device. Background Art

[0002] In industrial processes, valve filter devices are widely used. Valve filter devices help prevent pipes and equipment from being blocked, thereby ensuring that the fluid flows at an appropriate flow rate. Most existing valve filter devices are uncertain about the cleaning time of the filter, and require manual judgment to determine the filtering and cleaning time. They cannot automatically determine the degree of blockage inside the valve, making it difficult to achieve automatic cleaning and impurity separation, resulting in inconvenient use and incomplete and insufficient cleaning, which leads to poor use results and affects normal work.

[0003] For example, the "anti-clogging pressure reducing valve with multiple filtering functions" disclosed in the Chinese invention patent (application number: CN202111519846.2) discloses in its specification: the pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjustment, and automatically maintains the outlet pressure stable by relying on the energy of the medium itself. From the perspective of fluid mechanics, the pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction. Then, relying on the adjustment of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range. The existing pressure reducing valve may be clogged with stains after long-term use due to the small internal space. The above patents can prove the defects of the prior art.

[0004] Therefore, we make improvements to this and propose an auxiliary valve filtering device. Summary of the invention

[0029] The present application sets the cleaning component 3 to use the scraper rod 304 to fit the top outer wall of the rotating fixed filter 203 tightly. When the fixed filter 203 is blocked, the hydraulic pressure inside the filter chamber 106 increases, so that the trigger component 6 is triggered, the rotating shaft 301 is connected to the driving component 4 and rotates. At the same time, the second auger blade 302 set on the rotating shaft 301 is used to make the interior of the fixed shaft 107 in a negative pressure state. Under the action of the pressure difference and the cooperation of the elliptical block 303 fixedly installed on the rotating shaft 301, the scraper rod 304 is moved back and forth.

The ends of the two compression rods 702 are fixedly installed with a compression plate 701; A driving groove 713 is formed through the outer wall of the toothed disc 707 , and a plurality of engaging grooves 708 are formed in a circumferential array on the inner wall of the driving groove 713 . The engaging grooves 708 can form an engaging design with the ball 705 .

[0031] By pressing the pressure plates 701 on both sides of the adjustment plate 105, the pressure rod 702 cooperates with the arc surface at the bottom of the drive sleeve 703 to move the drive sleeve 703 downward, so that the limit of the ball 705 is released, and the clamping column 706 fixedly installed on the top of the adjustment plate 105 can be inserted into the base 104, and the ball 705 and the clamping groove 708 opened in the toothed disc 707 form a clamping fit, and at the same time, the interior of the fixed shaft 107 is connected to the collection groove 712 opened in the adjustment plate 105 through the drive sleeve 703.

Specifically, Figure 3 and Figure 5 As shown, a dynamic component 5 is provided at the bottom of the dynamic filter 206 located at the bottom of the sleeve roller 205, and the dynamic component 5 includes a reciprocating screw groove 501 opened on the outer wall of a plurality of driving rods 403 located between the first filter roller 201 and the second filter roller 202, and a screw block 502 is slidably installed on the outer wall of the plurality of driving rods 403, and the screw block 502 and the reciprocating screw groove 501 are designed to be threadedly connected, and two limit plates 503 are symmetrically installed on the outer wall of the screw block 502, and a dynamic roller 504 is rotatably installed between the two limit plates 503, and a plurality of corrugated plates 505 are installed in an array at the bottom of the dynamic filter 206 located at the bottom of the sleeve roller 205, and the corrugated surfaces of the plurality of corrugated plates 505 are designed to abut against the outer wall of the dynamic roller 504, and a reset spring 506 is provided between the top of the fixed filter 203 and the bottom of the dynamic filter 206, and a first auger blade 204 is fixedly installed inside the second filter roller 202.

[0033] By setting up the dynamic component 5 and utilizing the reciprocating screw groove 501 opened on the outer wall of the driving rod 403, the screw block 502 is moved back and forth under the rotation of the driving rod 403. Under the cooperation of the movable roller 504 set on the screw block 502 and the corrugated plate 505 set at the bottom of the fixed filter screen 203, the movable filter screen 206 is moved up and down relative to the fixed filter screen 203 through the reset spring 506 set between the top of the fixed filter screen 203 and the bottom of the movable filter screen 206, so that the filtered liquid between the fixed filter screen 203 and the movable filter screen 206 is continuously squeezed, thereby changing the path and speed of the filtered liquid flow, thereby optimizing the filtering effect, and dynamically adjusting the fixed filter screen 203 and the movable filter screen 206. The distance between them can help reduce the accumulation of stains on the filter material, thereby reducing clogging and maintaining the long-term effective operation of the filter. At the same time, by arranging the first auger blade 204 inside the second filter roller 202, the spiral channel of the first auger blade 204 is filled with various minerals, which can perform secondary filtration on the filtered liquid and improve the filtering effect. Under the action of the water impeller 401, the second filter roller 202 rotates, and under the action of the first auger blade 204, the filtered liquid is transported to the bottom of the filter chamber 106, thereby increasing the flow rate of the filtered liquid inside the filter chamber 106, further improving the filtering efficiency while preventing stains from clogging the fixed filter screen 203 and the dynamic filter screen 206.

[0034] The use process of the auxiliary valve filter device provided by the present invention is as follows: First, when the fixed filter 203 and the dynamic filter 206 are blocked, the pressure in the filter chamber 106 increases, so that the piston rod 604 slidably installed on the fixed shaft 107 is displaced, and the conical block 601 slidably installed on the top of the rotating shaft 301 is displaced upward through multiple piston rods 604, so that the cross protrusion 607 on the top of the conical block 601 is connected with the cross groove 605 at the bottom of the water impeller 401, thereby driving the rotating shaft 301 to rotate, and the first auger blade 204 is fixedly installed on the outer wall of the rotating shaft 301 to make the interior of the fixed shaft 107 in a negative pressure state, so that the scraper rod 304 is displaced toward the inside of the fixed shaft 107, so that the adsorption hole 305 has a certain suction force under the action of the discharge hole 306 and the adsorption hole 305, and the scraper rod 304 is moved back and forth under the action of the elliptical block 303 fixedly installed on the rotating shaft 301, which can prevent the scraper rod 304 from affecting the fixed filter. The outer wall of the net 203 is continuously sucked, thereby causing waste of filtered liquid. By setting the adjustment plate 105, the limit of the ball 705 is released by pressing the pressure plate 701, so that the driving sleeve 703 fixedly installed on the top of the adjustment plate 105 can be embedded in the base 104, so that the interior of the fixed shaft 107 is connected with the collection groove 712 opened in the adjustment plate 105, so that the stains adsorbed by the scraper rod 304 can be collected, and the adjustment plate 105 can be removed by the pressure plate 701, and the collected stains can be centrally cleaned. The ball 705 and the clamping groove 708 opened in the toothed disc 707 can be engaged by rotating the adjustment plate 105 to drive the toothed disc 707 to rotate, thereby driving the second gear 710 to rotate, realizing the angle adjustment of the valve plate 709, thereby realizing the opening and closing of the valve filter device, and realizing the flow adjustment of the valve filter device at the same time; By setting up the dynamic component 5 and utilizing the reciprocating screw groove 501 opened on the outer wall of the driving rod 403 opened on the driving rod 403, the screw block 502 is moved back and forth under the rotation of the driving rod 403, and the movable roller 504 set on the screw block 502 cooperates with the corrugated plate 505 set at the bottom of the fixed filter 203, and through the reset spring 506 set between the top of the fixed filter 203 and the bottom of the movable filter 206, the movable filter 206 is displaced up and down relative to the fixed filter 203, so that the filtered liquid between the fixed filter 203 and the movable filter 206 is continuously squeezed, thereby changing the path and speed of the filtered liquid flow, thereby optimizing the filtering effect, and dynamically adjusting the distance between the fixed filter 203 and the movable filter 206 can help reduce the accumulation of stains on the filter material, thereby reducing clogging and maintaining the long-term effective operation of the filter.
