Description

Technical Field

[0001] The present invention belongs to the technical field of filter press maintenance, and specifically relates to an anti-overflow filter press unit. Background Art

[0002] A filter press is an important solid-liquid separation device and plays an indispensable role in modern industry. Generally, based on the pressure difference, it prompts the liquid to pass through the filter medium. The solid particles in the liquid will be retained in the filter medium and form a filter cake on the filter plate. The formation of the filter cake will inevitably affect the subsequent filtration quality and working time. Therefore, the factory needs to regularly clean the filter cake. Even though some machines are equipped with self-cleaning functions, due to the long-term extrusion of the filter plate by pressure, there will still be some impurities that are difficult to clean on it. After long-term operation, the adhered impurities will block the filter material plate, resulting in the overflow of materials in the subsequent filter press.

[0003] Each filter plate of the filter press can usually be recycled multiple times, which requires the factory to be very cautious when cleaning the filter plate later to avoid damaging the filter cloth on the filter plate. In the existing technical means of cleaning the filter plate, generally, the filter cake is removed by manual flushing. However, it should be noted that this cleaning method not only consumes a large amount of labor cost, but also when manually cleaning the filter cake with a high-pressure water gun, when encountering difficult-to-remove places on the filter plate, usually the pressure of the water gun and the spraying time are increased to avoid the overflow of materials in the subsequent machine. However, excessive pressure and long-time spraying are very likely to cause deformation of the filter cloth, thus reducing the filtration quality of the filter plate. For this reason, we provide an anti-overflow filter press unit. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides an anti-overflow filter press unit, which solves the problem that when the existing cleaning solution uses a high-pressure water gun to clean the filter cake, when encountering difficult-to-remove places on the filter plate, usually the pressure of the water gun and the spraying time are increased, and excessive pressure and long-time spraying are very likely to cause deformation or even damage of the filter cloth.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] Through the cooperation of structures such as the cleaning assembly and the double-shaft motor, the double-shaft motor drives the first mounting limiting frame to rotate. Water pressure and centrifugal force are simultaneously applied to each filter material. At this time, the positioning rods on the same horizontal line will be closely attached together. There are also gaps between the filter materials. Each sponge strip will also be closely attached to the side of the filter material. The second mounting limiting frame moves up and down reciprocally through the reciprocating threaded shaft, so that the sponge strip washes the filter material. The dropped impurities are thrown out by the centrifugal force. Through the washing of the sponge strip and the fixation of the position of the filter material by water pressure and centrifugal force, the situation that the filter material is forcibly damaged and deformed during the cleaning process will be reduced, but the efficiency of cleaning the filter cake will not be reduced.

[0024] Through the cooperation of structures such as a collection component and a filtering component, most of the impurities discharged by centrifugal force are guided by the inclined design of the diversion plate on one side of the bracket, and the impurities will enter the interior of the bracket. A small part of the impurities adhering to the filter plate are removed by the shovel plate. Due to the inclined design of the shovel plate, the removed impurities enter the interior of the bracket and finally enter its interior through the opening of the filter cylinder. When the output shaft of the dual-axis motor drives the turbine to reverse, the rubber tube sprays water into the working box, and the water flow flushes the impurities on the filter plate. Guided by the inclined design of the diversion plate on the other side of the bracket, the impurities enter the interior of the bracket and stay on the baffle in the bracket, thus effectively cleaning the impurities on the filter plate and reducing the subsequent manual cleaning time.

[0025] Through the cooperation of structures such as a collection component and a filtering component, when the first limit frame rotates forward, the first limit block contacts the second limit block, and the end of the shovel plate only restricts the first limit block from tipping over to the side of the second limit block. The first limit block flips over the second limit block, and the fourth limit block restricts the limit plate to only be able to flip in the direction of the third limit block. During the process of the shovel plate scraping the filter plate, it will not rotate along with the shovel plate, so as to better carry out the scraping work. When the first limit frame rotates in reverse, the first limit block pushes the filter plate to rotate through the second limit block, the third limit block passes by the limit plate from the other side, and the limit plate will also flip and reset through the second spring piece. The filter plate rotates, so that when the rubber tube sprays water into the working box, it can more comprehensively backwash the impurities on the filter plate. Brief Description of the Drawings

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 9 shown, the present invention provides an anti-overflow pressure filter unit, including a base 1 and a filter media 10, and further including;

[0038] A working box 2 arranged on the top of the base 1;

[0039] A closing component 3 installed on the top of the working box 2, and the closing component 3 is used to close the interior of the working box 2;

[0040] A double-shaft motor 7 arranged at the bottom of the base 1, and a planetary gear set 8 installed at the bottom of the double-shaft motor 7;

[0041] A cleaning component 4 rotatably installed inside the working box 2;

[0042] The cleaning component 4 includes a first limiting frame 41 rotatably installed inside the working box 2. The output shaft of the double-shaft motor 7 movably penetrates the interior of the working box 2 and is in transmission connection with the bottom of the first limiting frame 41. A reciprocating threaded shaft 42 fixedly installed inside the working box 2 is rotatably installed inside the first limiting frame 41. A second limiting frame 43 is threadedly sleeved on the outer circumference of the reciprocating threaded shaft 42. A plurality of sponge strips 45 are slidably installed on the second limiting frame 43. A positioning rod 44 is slidably installed equidistantly inside the first limiting frame 41. Four sides at the lower end of the first limiting frame 41 are respectively provided with a flow channel 46;

[0043] Every two vertically symmetrical positioning rods 44 form a group, and the filter material 10 is clamped in the groove on each group of positioning rods 44, and the filter material 10 is located between every two adjacent sponge strips 10;

[0044] Four collecting components 6 respectively installed at the four corners of the cleaning component 4;

[0045] A filter assembly 9 is arranged on the inner wall of the working box 2, and a collecting assembly 6 is used to scrape and collect impurities on the filter assembly 9;

[0046] A reflux assembly 5 is installed at the bottom of the base 1 and communicated with the interior of the working box 2 , and a dual-axis motor 7 is connected to the reflux assembly 5 through a planetary gear set 8 .

[0047] The outer periphery of the second limiting frame 43 is matched with the interior of the first limiting frame 41 , and the second limiting frame 43 moves vertically inside the first limiting frame 41 .

[0048] Adopting the above scheme: in the initial state of the device, the second limiting frame 43 is located at the lower end of the first limiting frame 41, and the filter material 10 is placed inside the first limiting frame 41 and is clamped in the groove of each group of positioning rods 44. At this time, the filter material 10 will always be in a vertical state, and because each positioning rod 44 can slide independently in the first limiting frame 41, and there is a gap between the positioning rods 44 on the same horizontal line, the filter material 10 can enter the interior of the first limiting frame 41 in an inclined state, so as not to be blocked by the edge of the second limiting frame 43;

[0049] Then, water is injected into the working box 2, and it is necessary to ensure that the water level is higher than the top of the filter material 10. At this time, the dual-axis motor 7 drives the limit frame 1 41 to rotate. Since the reciprocating threaded shaft 42 is in a fixed state and the limit frame 2 43 can only move vertically inside the limit frame 1 41, the limit frame 2 43 rotates synchronously with the limit frame 1 41. During the rotation process, water pressure and centrifugal force are simultaneously applied to each filter material 10. At this time, each positioning rod 44 located on the same horizontal line will be tightly together, and there will also be gaps between each filter material 10. Each sponge strip 45 will also be tightly attached to the side of the filter material 10;

[0050] The second limit frame 43 is continuously reciprocated up and down by the reciprocating threaded shaft 42, so that the sponge strip 45 washes the filter material 10, and the impurities dropped are thrown out by the centrifugal force. The washing of the sponge strip 45 and the fixing of the position of the filter material 10 by the water pressure and the centrifugal force will reduce the situation that the filter material 10 is forcibly damaged and deformed during the cleaning process.

[0051] Part of the impurities adhere to the filter component 9, while the rest will be collected by the collection component 6. Similarly, the collection component 6 will also scrape and collect the impurities on the filter component 9, further improving the slag removal efficiency of the device, thereby preventing subsequent overflow.

[0052] As shown Figures 1 - 3 in FIG. 1, the closed component 3 includes a handle 32 rotatably mounted on the top of the working box 2. A rubber plate 31 is sleeved on the outer periphery of the handle 32 with threads. One feeding groove 33 is symmetrically formed at each of the two ends of the top of the working box 2.

[0053] Adopting the above scheme: Before the device starts to work, rotate the rubber plate 31 so that its bottom aligns with the feeding groove 33. Subsequently, manually fix the position of the rubber plate 31 and rotate the handle 32. The threaded design on its outer periphery can make the rubber plate 31 descend and block the feeding groove 33. At this time, the water generated during the cleaning work of the cleaning component 4 inside the working box 2 will not splash outwards, thereby improving the cleanliness of the device during operation and reducing the time for subsequent staff to clean the ground.

[0054] As shown Figures 1 - 5 in FIG. 2, the reflux component 5 includes a reflux box 51 fixedly installed at the bottom of the planetary gear set 8. The output shaft of the double-shaft motor 7 is in transmission connection with the input shaft of the planetary gear set 8. The output shaft of the planetary gear set 8 movably penetrates through the top of the reflux box 51 and is in transmission connection with a turbine 52. The bottom of the reflux box 51 is communicated with the outer periphery of the working box 2 through a plurality of rubber tubes 53 distributed at equal angles in the circumferential direction. The top of the reflux box 51 is communicated with the bottom of the working box 2 through a plurality of reflux tubes 54 distributed at equal angles in the circumferential direction. The planetary gear set 8 is used to increase the rotation speed of the turbine 52 driven by the double-shaft motor 7.

[0055] A notch is provided at the bottom of the first limiting frame 41, and the notch is located above the connection end of the reflux tube 54 and the working box 2.

[0056] Adopting the above scheme: After the output shaft of the double-shaft motor 7 is speeded up by the planetary gear set 8, it is transmitted to the turbine 52, so that the rotation speed of the turbine 52 increases, and then the water in the working box 2 is pumped out through the rubber tubes 53 faster and output to the bottom of the working box 2 through the reflux tubes 54. The pumped water will also pass through the filtering component 9 in advance, so that impurities are retained on the filtering component 9. The water re-entering the working box 2 through the reflux tubes 54 will no longer contain impurities, and the water flow will also pass through the notch at the bottom of the first limiting frame 41, so that it can wash the filter material 10 inside the first limiting frame 41 as much as possible, thereby accelerating the cleaning efficiency of the filter cake;

[0057] After the cleaning work is completed, after one of the rubber tubes 53 is disassembled from the bottom of the reflux box 51, control the output shaft of the double-shaft motor 7 to reverse. At this time, the drainage of the reflux tube 54 into the working box 2 is changed to pumping water, which further accelerates the drainage speed inside the working box 2.

[0058] As shown Figure 1 、 Figure 2 and Figures 6 - 9As shown, the collecting assembly 6 includes a bracket 61 installed on a limit frame 41, and inclined guide plates 62 are equidistantly arranged on both sides of the bracket 61, and every two guide plates 62 located on both sides of the bracket 61 are staggered. A filter cartridge 64 is installed inside the bracket 61, and the outer periphery of the filter cartridge 64 is open and connected with the inside of the bracket 61. A shovel plate 63 is fixedly installed on the side of the bracket 61 that has the same rotation direction as the output shaft of the dual-axis motor 7. The filtering assembly 9 includes a filter plate 91 rotatably installed inside the working box 2, and the end of the shovel plate 63 abuts against the inner wall of the filter plate 91.

[0059] The above scheme is adopted: when the limit frame 41 rotates, it will also drive the brackets 61 at the four corners to rotate at the same time, and most of the impurities discharged by the centrifugal force will first contact the side of the bracket 61, and the impurities will enter the interior of the bracket 61 through the guidance of the inclined design of the guide plate 62 on one side of the bracket 61. Similarly, the shovel plate 63 always contacts the filter plate 91, so that a small part of the impurities adhering to the filter plate 91 will be shoveled away by the shovel plate 63, and through the inclined design of the shovel plate 63, the shoveled impurities will also enter the interior of the bracket 61, and finally enter the interior of the filter cartridge 64 through the opening of the filter cartridge 64. Furthermore, it can reduce the time for subsequent manual maintenance and cleaning of impurities inside the working box 2, thereby indirectly improving the working efficiency of the device;

[0060] When the output shaft of the dual-axis motor 7 drives the turbine 52 to reverse, the return pipe 54 draws water from the bottom of the working box 2 and transfers it to the rubber tube 53 inside the return box 51. When the water is injected into the working box 2 again through the rubber tube 53, the water flow will flush the impurities on the filter plate 91;

[0061] Furthermore, impurities that fall off the filter plate 91 will preferentially contact the side of the bracket 61, and every two guide plates 62 located on both sides of the bracket 61 are staggered. The bracket 61 is reversed, and the water flows toward the center of the working box 2. After being guided by the inclined design of the guide plate 62 on the other side of the bracket 61, the impurities will still enter the interior of the bracket 61 and be retained in the baffle inside the bracket 61, thereby effectively cleaning the impurities on the filter plate 91 and reducing the time for subsequent manual cleaning.

[0062] like Figure 1 , Figure 2 and Figures 6 - 9 As shown, a baffle for blocking two rows of guide plates 62 is provided inside the bracket 61 , and the collecting assembly 6 also includes a knob cover 65 threadedly mounted on the top of the filter cartridge 64 , and the top of the filter cartridge 64 is movably engaged with the top of the bracket 61 .

[0063] Adopting the above solution: After the cleaning work of the device is completed, the filter cartridge 64 can be directly lifted out through the knob cover 65, and the knob cover 65 is rotated to open, so that the filter cartridge 64 can be better cleaned. The protruding part of the filter cartridge 64 is clamped with the top of the bracket 61, which makes the opening of the filter cartridge 64 always dock with the inside of the bracket 61, thereby improving the stability of the device during operation.

[0064] As Figures 1 - 9 shown, the collection assembly 6 further includes a first limiting block 67 hinged to the end of the shovel plate 63. The middle of the first limiting block 67 is elastically connected to the side of the shovel plate 63 through a first spring piece 66. The filtering assembly 9 further includes a plurality of second limiting blocks 92 equidistantly installed on the inner wall of the filter material plate 91 and located on the traveling route of the first limiting block 67. A plurality of fourth limiting blocks 94 are equidistantly installed on the inner wall of the working box 2. A limiting plate 96 that abuts against the outer periphery of the filter material plate 91 is hinged to the side of the fourth limiting block 94. The inner wall of the working box 2 is elastically connected to the limiting plate 96 through a second spring piece 95. A plurality of third limiting blocks 93 for blocking the limiting plate 96 are provided on the outer periphery of the filter material plate 91.

[0065] Adopting the above solution: When the first limiting frame 41 rotates forward, the bracket 61 drives the shovel plate 63 to scrape the inner wall of the filter material plate 91. At this time, the first limiting block 67 will contact the second limiting block 92. Due to its hinged structure, the end of the shovel plate 63 only restricts the first limiting block 67 from turning over to the side of the second limiting block 92, which makes the first limiting block 67 finally turn over and cross the second limiting block 92;

[0066] The third limiting block 93 always abuts against the limiting plate 96, and the fourth limiting block 94 restricts the limiting plate 96 to only turn over in the direction of the third limiting block 93. This makes the shovel plate 63 not rotate along with the shovel plate 63 during the process of scraping the filter material plate 91, so as to better perform the scraping work;

[0067] When the first limiting frame 41 rotates reversely, blocked by the end of the shovel plate 63, the first limiting block 67 can push the filter material plate 91 to rotate through the second limiting block 92. When the third limiting block 93 passes by the limiting plate 96 from the other side, the limiting plate 96 will also turn over and reset through the second spring piece 95. At this time, the filter material plate 91 rotates, so that when the rubber tube 53 sprays water into the working box 2, the impurities on the filter material plate 91 can be more comprehensively backwashed.

[0068] The working principle and usage process of the present invention:

[0069] In the initial state of the device, the second limit frame 43 is located at the lower end of the first limit frame 41. At this time, the filter material 10 is placed inside the first limit frame 41 and is clamped in the grooves of each group of positioning rods 44. At this time, the filter material 10 will always be in a vertical state. And since each positioning rod 44 can slide independently inside the first limit frame 41, and there are gaps reserved between the positioning rods 44 on the same horizontal line, this enables the filter material 10 to enter the inside of the first limit frame 41 in an inclined state, so that it will not be blocked by the edge of the second limit frame 43;

[0070] Subsequently, water is injected into the working box 2, and it is necessary to ensure that the water level line is higher than the top of the filter material 10. At this time, the double-shaft motor 7 drives the first limit frame 41 to rotate. Since the reciprocating threaded shaft 42 is in a fixed state and the second limit frame 43 can only move vertically inside the first limit frame 41, this causes the second limit frame 43 to rotate synchronously with the first limit frame 41. During the rotation process, water pressure and centrifugal force are simultaneously applied to each filter material 10. At this time, the positioning rods 44 on the same horizontal line will be closely attached to each other, there are also gaps between each filter material 10, and each sponge strip 45 will also be closely attached to the side of the filter material 10

[0071] The second limit frame 43 continuously moves up and down through the reciprocating threaded shaft 42, so that the sponge strip 45 washes the filter material 10, and the fallen impurities are thrown out by the centrifugal force;

[0072] When the first limit frame 41 rotates, it will also drive the brackets 61 at the four corners to rotate simultaneously. Most of the impurities discharged by the centrifugal force will first contact the side of the bracket 61. Under the guidance of the inclined design of the diversion plate 62 on one side of the bracket 61, the impurities will enter the inside of the bracket 61. Similarly, the shovel plate 63 always abuts against the filter plate 91, which causes a small part of the impurities adhering to the filter plate 91 to be shoveled by the shovel plate 63. And through the inclined design of the shovel plate 63, the shoveled impurities will also enter the inside of the bracket 61 and finally enter its inside through the opening of the filter cylinder 64;

[0073] After the output shaft of the double-shaft motor 7 is speeded up by the planetary gear set 8, it is transmitted to the turbine 52, which further increases the rotation speed of the turbine 52. Then it can pump the water in the working box 2 faster through the rubber tube 53 and output it to the bottom of the working box 2 through the return pipe 54. And the pumped water will also pass through the filter assembly 9 in advance to retain the impurities on the filter assembly 9. When the cleaning work is completed, after one of the rubber tubes 53 is disassembled from the bottom of the return box 51, the output shaft of the double-shaft motor 7 is controlled to reverse. At this time, the drainage of the working box 2 by the return pipe 54 is changed to pumping, so as to accelerate the drainage speed of the working box 2.
