Filter bag cleaning mechanism for filter press

Abstract

This invention belongs to the field of filter press technology and discloses a filter bag cleaning mechanism for a filter press, including a cleaning box filled with cleaning water, and a cleaning component disposed inside the cleaning box. The invention utilizes a first connecting component and a second connecting component engaged with the outside of a protruding rod. A drive motor rotates a support rod and a transmission belt, simultaneously pushing a transmission rod downwards. A slider inside the docking frame engages with a spiral groove, causing the transmission rod to rotate and move downwards. This, in turn, rotates the docking plate, the first support, and one end of the filter bag, making the filter bag knob-shaped and compressing a coil spring. As the filter bag rotates, the externally fixed solidified material deforms and detaches from the filter bag. Simultaneously, the cleaning water inside the cleaning box softens the solidified material, improving the cleaning effect while preventing damage to the filter bag and ensuring its service life.

Description

Technical Field

[0001] This invention belongs to the field of filter press technology, specifically a filter bag cleaning mechanism for filter presses. Background Technology

[0002] A bag filter press consists of a frame, filter bags, a feeding system, a pressing system, and a control system. Its core component is the filter bag, typically made of polyester fiber or other synthetic materials, which possesses high strength and chemical resistance. During operation, the liquid to be filtered enters the equipment through a high-pressure pump and passes through the filter bag under pressure. Solid particles are trapped, while the liquid is discharged. The filter bag is the core filtration element of the filter press. Bag filter presses are usually designed with a backwashing function, which can directly remove solid impurities and dirt from the surface of the filter bag through backwashing. However, after long-term use, solid impurities adhering to the surface of the filter bag will accumulate. For materials that are too stubborn (such as clumps, gels, or highly viscous substances), backwashing cannot thoroughly clean them. Currently, most equipment still uses traditional cleaning methods, which involve manually disassembling the filter bags and then cleaning them with a brush and a high-pressure water gun. This cleaning method has many drawbacks. First, manual operation can easily damage the filter bags due to improper force, shortening their service life. Second, brush cleaning can only remove particulate matter on the surface of the filter bags, and it is difficult to completely remove fine particles or sticky substances attached to the deep layers of the filter bags, resulting in unsatisfactory cleaning results. Therefore, a filter bag cleaning mechanism for filter presses is proposed. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides a filter bag cleaning mechanism for filter presses. This mechanism solves the problem that in existing manual filter bag disassembly and cleaning with a brush and high-pressure water gun, manual operation can easily damage the filter bags due to improper force, thus shortening their service life.

[0005] Preferably, the cleaning assembly includes two drive belts, and the interior of the cleaning box is provided with a support rod for supporting the two drive belts, with protruding rods fixedly mounted on the two drive belts.

[0006] The docking member engages with the second connecting assembly on the outside of the protrusion; The cleaning box is equipped with a drive motor on its exterior for driving the support rod and transmission belt to rotate.

[0007] Preferably, the first connecting component and the second connecting component clamp the filter bag, and the filter bag is in a non-tensioned state; The first connecting component rotates with the transmission belt to the upper end of the rotating component. The docking rod engages inside the transverse groove. The cleaning component and the first connecting component push the transmission rod to rotate and move the first connecting component downward, compressing the coil spring.

[0008] Preferably, the rotating assembly further includes a connecting frame fixedly mounted to the lower end of the transmission rod, a first magnet being fixedly mounted at the bottom of the connecting frame, and a second magnet being coaxially and vertically aligned with the first magnet at the bottom of the cleaning box; The second magnet has springs at both ends that push the connecting frame and the transmission rod upward.

[0009] Preferably, the first connecting assembly further includes a first clamping plate movably disposed on the first bracket via a first screw; One end of the filter bag is placed between the first bracket and the first clamping plate. By rotating the first screw, one end of the filter bag can be fixed by the first clamping plate.

[0010] Preferably, the docking component includes a transmission ring movably sleeved on the outside, a spring piece on the docking component that pushes the transmission ring downward, and a ball bearing movably disposed inside the docking component; The docking component has an annular groove in the middle for ball bearing engagement.

[0011] Preferably, the second connecting assembly includes a connector, the connector having the same structure as the mating member, the connector engaging with the outside of the protruding rod, and the two connectors being connected by a second crossbeam; A push rod is fixed between the two connecting parts, and a second bracket is fixed to the side of the push rod. A second clamping plate is movably mounted on the second bracket via a second screw.

[0012] Preferably, the transmission assembly includes a transmission plate hinged to the side of the fixed frame, the lower end of the transmission plate having a rectangular groove, a partition plate being movably installed on the side of the fixed frame, and a connecting rod being fixedly installed at one end of the partition plate within the rectangular groove; A counterweight is fixedly mounted at the lower end of the transmission plate, and a push rod is fixedly mounted at the top of the second crossbeam; During the rotation of the second crossbeam, the transmission plate and the partition plate are moved by the push rod.

[0013] Preferably, the side edges of the opposing surfaces of the first magnet and the second magnet are arc-shaped, and the thickness of the partition plate gradually decreases near the end of the second magnet.

[0014] Preferably, the cleaning assembly further includes a cleaning rod fixed inside the cleaning box, and four cleaning rods are arranged alternately at different heights inside the cleaning box.

The cleaning rod and the support rod are equipped with limiting rings to limit the movement of the transmission belt; The two cleaning rods at the top are provided with grooves to allow the first connecting component and the second connecting component to operate normally.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a first connecting component and a second connecting component that engage with the outside of a protruding rod. A drive motor drives a support rod and a transmission belt to rotate, causing the first connecting component, filter bag, and second connecting component to rotate as well. When the first connecting component rotates above the rotating component, as it continues to move downwards, the docking rod engages with the inside of the transverse groove, simultaneously pushing the transmission rod downwards. The slider inside the docking frame cooperates with the spiral groove, causing the transmission rod to rotate downwards. This, in turn, causes the docking plate, the first support, and one end of the filter bag to rotate, making the filter bag into a knob shape and compressing the coil spring. As the filter bag rotates, the solidified material outside deforms and detaches from the filter bag. Meanwhile, the cleaning box is filled with cleaning water, which softens the solidified material, improves the cleaning effect, and avoids damage to the filter bag, thus ensuring its service life. This invention uses a water pump to inject water into the distribution box. The water enters the four cleaning rods and is discharged through the spray holes. The water is then carried by a transmission belt that passes around the outside of the four cleaning rods in sequence. The water sprayed through the four spray holes washes both sides of the filter bag. Since the filter bag is not taut, it is blown by the water pressure, which improves the cleaning effect of the filter bag. Attached Figure Description

[0018] 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.

[0019] like Figures 1 to 9 As shown, the present invention provides a filter bag cleaning mechanism for a filter press, including a cleaning tank 1, the interior of which is filled with cleaning water, and further comprising: Cleaning component 6 is located inside the cleaning box 1; The filter bag 3 is held by the first connecting component 2 and the second connecting component 4, and the first connecting component 2 and the second connecting component 4 are engaged on the transmission belt 61 of the cleaning component 6; Rotating component 5 is disposed inside the cleaning box 1; Transmission assembly 7 is disposed on the side of rotation assembly 5; The first connecting component 2 includes docking parts 21 that are respectively engaged with the transmission belt, a first crossbeam 23 connecting the two docking parts 21, a docking cover 22 fixedly mounted on the side of the first crossbeam 23, a first bracket 26 movably sleeved on the middle of the first crossbeam 23, a coil spring 29 fixedly mounted on the middle of the first bracket 26, and the outside of the coil spring 29 connected to the inner wall of the docking cover 22. A docking plate 25 is fixedly mounted on the side of the first bracket 26, and transverse grooves 24 are provided at both ends of the docking plate 25. The rotating assembly 5 includes a fixed frame 51 fixed inside the cleaning box 1, a docking frame 52 fixed on the fixed frame 51, a transmission rod 54 movably sleeved inside the docking frame 52, a spiral groove 55 opened on the outside of the transmission rod 54, a slider engaged in the spiral groove 55 fixed on the inner wall of the docking frame 52, and docking rods 53 fixed at both ends of the top of the transmission rod 54. The cleaning assembly 6 includes two drive belts 61. The cleaning box 1 has a support rod 63 inside for supporting the two drive belts 61. The two drive belts 61 are fixed with protruding rods 62.

[0020] The docking part 21 engages with the second connecting assembly 4 on the outside of the protrusion 62; The cleaning box 1 is externally equipped with a drive motor for rotating the support rod 63 and the transmission belt 61. In this specification, the support rod 63 and the transmission belt 61 rotate in coordination, and gear and chain drives can be replaced without deviating from the scope of this application.

[0021] like Figure 7 and Figure 8As shown, the first connecting component 2 and the second connecting component 4 clamp the filter bag 3, and the filter bag 3 is in a non-tensioned state. The first connecting component 2 rotates with the transmission belt 61 to the upper end of the rotating component 5. The docking rod 53 engages inside the transverse groove 24. The cleaning component 6 and the first connecting component 2 push the transmission rod 54 to drive the first connecting component 2 to rotate and move downward, and compress the coil spring 29.

[0022] The filter bag 3 is held at both ends by the first connecting component 2 and the second connecting component 4. The first connecting component 2 and the second connecting component 4 are engaged with the outside of the protruding rod 62. The drive motor drives the support rod 63 and the transmission belt 61 to rotate, so that the first connecting component 2, the filter bag 3 and the second connecting component 4 rotate together. When the first connecting component 2 rotates to the top of the rotating component 5, as the first connecting component 2 continues to move downward, the docking rod 53 engages with the inside of the transverse groove 24, and at the same time pushes the transmission rod 54 to move downward. The connecting frame 58 compresses the spring 59. The slider inside the docking frame 52 cooperates with the spiral groove 55, so that the transmission rod 54 rotates downward. At the same time, it drives the docking plate 25, the first bracket 26 and one end of the filter bag 3 to rotate, so that the filter bag 3 is in a knob shape and the coil spring 29 is compressed. As the filter bag 3 rotates, the externally fixed separation material deforms and can be separated from the filter bag 3. At the same time, the inside of the cleaning box 1 is filled with cleaning water, which can soften the solidified material, improve the cleaning effect of the solidified material, and avoid damage to the filter bag 3, thus ensuring the service life of the filter bag 3.

[0023] like Figure 7 and Figure 9 As shown, the rotating assembly 5 also includes a connecting frame 58 fixedly mounted on the lower end of the transmission rod 54. A first magnet 56 is fixedly mounted on the bottom of the connecting frame 58, and a second magnet 57 is coaxially and vertically aligned with the first magnet 56 at the bottom of the cleaning box 1. The second magnet 57 has springs 59 at both ends that push the connecting frame 58 and the transmission rod 54 upward.

[0024] As the first connecting assembly 2, filter bag 3, and second connecting assembly 4 rotate with the transmission belt 61, the transmission rod 54 is pushed to rotate and move downward. During the downward movement, the first magnet 56, under the magnetic force of the second magnet 57, causes the docking rod 53 to move downward and disengage from the interior of the transverse groove 24. At this time, the coil spring 29 drives the first support 26 and one end of the filter bag 3 to rotate in opposite directions. Under the action of the coil spring 29, the first support 26 and the filter bag 3 are reset to a horizontal state. The knob is turned and the filter bag 3 is loosened in sequence to improve the cleaning effect of the attached solidified material.

[0025] like Figures 3-5 As shown, the first connecting assembly 2 also includes a first clamping plate 27 that is movably mounted on the first bracket 26 via a first screw 28; One end of the filter bag 3 is placed between the first bracket 26 and the first clamping plate 27. By rotating the first screw 28, one end of the filter bag 3 can be fixed by the first clamping plate 27. The docking component 21 includes a transmission ring 213 movably sleeved on the outside, a spring piece 212 that pushes the transmission ring 213 downward on the docking component 21, and a ball bearing 211 movably disposed inside the docking component 21. The middle part of the docking part 21 is provided with an annular groove for the ball 211 to engage; The second connecting component 4 includes a connector 41, which has the same structure as the docking component 21. The connector 41 is engaged with the outside of the protrusion 62, and the two connectors 41 are connected by the second crossbeam 42. A push rod 74 is fixed between the two connectors 41, and a second bracket 43 is fixed to the side of the push rod 74. A second clamping plate 44 is movably mounted on the second bracket 43 via a second screw 45.

[0026] With the filter bag 3 fixed at both ends to the first connecting component 2 and the second connecting component 4 respectively, pulling the transmission ring 213 upward to release the pressure on the ball bearing 211 allows the docking part 21 and the connecting part 41 to be fitted onto the outside of the protruding rod 62. By releasing the transmission ring 213, the ball bearing 211 is engaged in the annular groove by the action of the spring piece 212. The filter bag 3 can then be installed on the transmission belt 61 and cleaned as it rotates. After cleaning, the transmission ring 213 can be lifted to remove the docking part 21 and the connecting part 41 from the outside of the protruding rod 62, allowing the next filter bag 3 to be cleaned to be replaced.

[0027] like Figure 7 and Figure 9 As shown, the transmission assembly 7 includes a transmission plate 71 hinged to the side of the fixed frame 51. A rectangular groove is provided at the lower end of the transmission plate 71. A partition plate 73 is movably installed on the side of the fixed frame 51. A connecting rod that moves within the rectangular groove is fixed at one end of the partition plate 73. The separator 73 is made of superconducting materials such as niobium-titanium alloy and yttrium barium copper oxide, and has a magnetic shielding effect; A counterweight 72 is fixedly installed at the lower end of the transmission plate 71, and a push rod 74 is fixedly installed at the top of the second crossbeam 42. During the rotation of the second crossbeam 42, the transmission plate 71 and the partition plate 73 are driven to move by the push rod 74. The side edges of the opposing surfaces of the first magnet 56 and the second magnet 57 are arc-shaped, and the thickness of the partition plate 73 gradually decreases near the end of the second magnet 57.

[0028] The first connecting component 2, filter bag 3 and second connecting component 4 are engaged on the transmission belt 61 and rotate into the cleaning box 1. Under the action of the rotating component 5, one end of the filter bag 3 rotates into a knob shape and then returns to its original position. The first magnet 56 and the second magnet 57 come into contact. As the transmission belt 61, the first connecting component 2, filter bag 3 and the second connecting component 4 continue to rotate, the filter bag enters the cleaning component 6 for rinsing. During the rotation of the push rod 74, the transmission plate 71 and the partition plate 73 are pushed, so that one end of the partition plate 73 is inserted between the first magnet 56 and the second magnet 57 for separation. Under the action of the spring 59, the transmission rod 54 moves in the opposite direction to return to its original position. When the push rod 74 disengages from the transmission plate 71, the transmission plate 71 moves in the opposite direction under the action of the counterweight 72, causing the partition plate 73 to reset.

[0029] like Figure 2 , Figure 6 and Figure 9 As shown, the cleaning assembly 6 also includes a cleaning rod 65 fixed inside the cleaning box 1. There are four cleaning rods 65 arranged alternately at different heights inside the cleaning box 1. The cleaning rods 65 are provided with spray holes 66. A diversion box 67 is fixed outside the cleaning box 1, and the cleaning rods 65 are connected to the inside of the diversion box 67. The cleaning rod 65 and the support rod 63 are provided with limiting rings 64 to limit the transmission belt 61; The two cleaning rods 65 at the top end have grooves at both ends to allow the first connecting assembly 2 and the second connecting assembly 4 to operate normally.

[0030] Water is pumped into the distribution box 67, and the water enters the four cleaning rods 65 and is discharged through the spray holes 66. The water is then sprayed through the four spray holes 66 and passes around the outside of the four cleaning rods 65 in sequence. Since the filter bag 3 is not taut, it is blown by the water pressure, which improves the cleaning effect of the filter bag 3. Since the transmission belt 61 passes over the cleaning rod 65 in sequence, the grooves opened at both ends of the two cleaning rods 65 can ensure that the first connecting component 2 and the second connecting component 4 installed on the outside of the protruding rod 62 can operate normally.

[0031] Working principle and usage process of this invention: By fixing the two ends of the filter bag 3 to the first connecting component 2 and the second connecting component 4 respectively, pulling the transmission ring 213 upward to release the pressure on the ball 211, the docking part 21 and the connecting part 41 can be sleeved on the outside of the protruding rod 62. By releasing the transmission ring 213, the ball 211 can be engaged in the annular groove by the action of the spring piece 212, and the filter bag 3 can be installed on the transmission belt 61. The drive motor drives the support rod 63 and the transmission belt 61 to rotate, causing the first connecting component 2, the filter bag 3 and the second connecting component 4 to rotate as well. When the first connecting component 2 rotates above the rotating component 5, as the first connecting component 2 continues to move downward, the docking rod 53 engages inside the transverse groove 24, and at the same time pushes the transmission rod 54 to move downward. The connecting frame 58 compresses the spring 59, and the slider inside the docking frame 52 cooperates with the spiral groove 55, causing the transmission rod 54 to rotate downward. At the same time, it drives the docking plate 25, the first bracket 26 and one end of the filter bag 3 to rotate, so that the filter bag 3 is in a knob shape and the coil spring 29 is compressed. As the filter bag 3 rotates, the externally fixed separation material deforms and can be separated from the filter bag 3. At the same time, the cleaning box 1 is filled with cleaning water, which can soften the solidified material and improve the cleaning effect of the solidified material. During the downward rotation of the transmission rod 54, the first magnet 56, under the magnetic force of the second magnet 57, causes the docking rod 53 to move downward and disengage from the inside of the transverse groove 24. At this time, the coil spring 29 drives the first support 26 and one end of the filter bag 3 to rotate in opposite directions. Under the action of the coil spring 29, the first support 26 and the filter bag 3 are reset to a horizontal state. The knob is turned and the filter bag 3 is loosened in sequence to improve the cleaning effect of the attached solidified material. When the first magnet 56 and the second magnet 57 come into contact, as the transmission belt 61, the first connecting assembly 2, the filter bag 3 and the second connecting assembly 4 continue to rotate, they enter the cleaning assembly 6 for rinsing. During the rotation of the push rod 74, it pushes the transmission plate 71 and the partition plate 73, so that one end of the partition plate 73 is inserted between the first magnet 56 and the second magnet 57 to separate them. Under the action of the spring 59, the transmission rod 54 moves in the opposite direction to reset. The water pump injects water into the distribution box 67. The water enters the four cleaning rods 65 and is discharged through the spray holes 66. The water is then sprayed through the four spray holes 66 and passes around the outside of the four cleaning rods 65 in sequence via the transmission belt 61. Since the filter bag 3 is not taut, it is blown by the water pressure, which improves the cleaning effect of the filter bag 3.
