Description

Technical Field

[0001] The present invention relates to the technical field of plate and frame filter presses, and specifically to a filter plate cleaning device for a plate and frame filter press. Background Technique

[0002] A plate and frame filter press is an intermittent solid-liquid separation device, widely used in chemical industry, dyeing, petroleum, ceramics, pharmaceuticals, sugar making, food, starch, maltose, paint, metallurgy, and sewage treatment in various industries. It has the advantages of good separation effect, wide application range, simple operation, and low investment. Especially for the separation of sticky and fine materials, it has incomparable superiority. However, after the plate and frame filter press performs the filtration work, a large amount of impurities will accumulate on the filter plates and filter meshes. Therefore, a corresponding cleaning device is needed to clean the filter plates and filter meshes.

[0003] Currently, during the use of existing filter plate cleaning devices, the methods of water cleaning and blade scraping are used to clean the impurities accumulated inside and on one side of the filter mesh. However, during the water cleaning process, nozzles are required, and the service lives of the nozzles and blades are limited. Manual replacement of the nozzles and blades needs to be carried out regularly, which is rather inconvenient.

[0004] Combining the above problems, we will find that it is very difficult to avoid the above-mentioned problems simultaneously when using the existing filter plate cleaning devices for plate and frame filter presses on the market. And even if it can be solved, external tools need to be cooperated to solve it, thus unable to achieve the desired effect.

[0023] As a further limitation of the present invention, the disassembly unit 21 includes a cleaning device body 2101. The outer surface of the cleaning device body 2101 is slidably connected to the inside of the filter press body 1. Inside the filter press body 1, there are a first rectangular plate 2106 and a second rectangular plate 2105. The bottom surface of the first rectangular plate 2106 is fixedly connected to the upper surface of the second rectangular plate 2105. The back surfaces of the first rectangular plate 2106 and the second rectangular plate 2105 are jointly fixedly connected with a first stress spring 2108. One end of the first stress spring 2108 away from the first rectangular plate 2106 is fixedly connected to the surface of the cleaning device body 2101. Four storage cylinders 2117 and a first spiral cylinder 2129 are rotatably connected to the inner wall of the first rectangular plate 2106. One end of each of the storage cylinder 2117 and the first spiral cylinder 2129 away from the first stress spring 2108 is fixedly connected with a first gear 2119. A first toothed belt 2118 is jointly engaged with the outer surfaces of the five first gears 2119. Four disassembly cylinders 2123 and a second spiral cylinder 2128 are rotatably connected to the inner wall of the second rectangular plate 2105. One end of each of the disassembly cylinder 2123 and the second spiral cylinder 2128 away from the first stress spring 2108 is fixedly connected with a second gear 2121. A second toothed belt 2120 is jointly engaged with the outer surfaces of the five second gears 2121. A first spiral shaft 2102 is slidably connected to the inside of the first spiral cylinder 2129. One end of the first spiral shaft 2102 passes through one of the first gears 2119 and extends to the front of the first gear 2119. A second spiral shaft 2103 is slidably connected to the inside of the second spiral cylinder 2128. One end of the second spiral shaft 2103 passes through one of the second gears 2121 and extends to the front of the second gear 2121. Circular holes 2122 are opened at one end of the other four second gears 2121 away from the first stress spring 2108.

The telescopic end of the cleaning device body 2101 is fixedly connected with a lifting spray water pipe 2130. Four high-pressure spray nozzles 2131 are threadedly connected to the outer surface of the lifting spray water pipe 2130. By providing the disassembly unit 21, the disassembly unit 21 can automatically replace the high-pressure spray nozzles 2131 in the cleaning device body 2101, thus effectively avoiding the problem that the service life of the high-pressure spray nozzles 2131 is relatively low during use and the high-pressure spray nozzles 2131 need to be replaced regularly.

[0024] Please refer to Figure 1 、 Figure 2 and Figure 7, four positioning shafts 2107 are fixedly connected to the inner wall of the cleaning device body 2101. The inner parts of the first rectangular plate 2106 and the second rectangular plate 2105 are both slidably connected to the outer surface of the positioning shaft 2107. By providing the positioning shaft 2107, the moving positions of the first rectangular plate 2106 and the second rectangular plate 2105 can be limited by utilizing the characteristics of the sliding of the first rectangular plate 2106 and the second rectangular plate 2105 on the surface of the positioning shaft 2107.

[0025] Please refer to Figure 7 , a fixing plate 2104 is fixedly connected to the left side surface of the cleaning device body 2101. The inner walls of the fixing plate 2104 are respectively rotatably connected with a third spiral cylinder 2127 and a fourth spiral cylinder 2115. The outer surface of the first spiral shaft 2102 is slidably connected to the inside of the third spiral cylinder 2127, and the outer surface of the second spiral shaft 2103 is slidably connected to the inside of the fourth spiral cylinder 2115. By providing the third spiral cylinder 2127 and the fourth spiral cylinder 2115, support forces can be provided for the first spiral shaft 2102 and the second spiral shaft 2103.

[0026] Please refer to Figure 7 , a transmission plate 2125 is fixedly connected to the upper surface of the magnet block 2109. The outer surface of the transmission plate 2125 is slidably connected to the inside of the rectangular frame 2110. By providing the transmission plate 2125, when the cleaning device body 2101 moves backward, the support and guidance for the movement of the magnet block 2109 can be realized through the transmission plate 2125, and the stability of the magnet block 2109 can be increased.

[0027] Please refer to Figure 9 , a baffle 2114 is fixedly connected to the inner wall of the filter press body 1. A collection box 2116 is slidably connected to the inside of the baffle 2114. By providing the collection box 2116, the waste replaced can be collected and processed by using the collection box 2116.

[0028] Please refer to Figure 7 and Figure 8 , eight tensioners 2124 are fixedly connected to the front surfaces of both the first rectangular plate 2106 and the second rectangular plate 2105. The outer surfaces of eight of the tensioners 2124 are in contact with the outer surface of the first toothed belt 2118, and the outer surfaces of the other eight tensioners 2124 are in contact with the outer surface of the second toothed belt 2120. By providing the tensioners 2124, the first toothed belt 2118 can be tensioned by using the tensioners 2124, and the problem that the toothed belt cannot transmit power to the gear can be prevented from occurring.

[0029] The specific implementation manner of this embodiment is as follows: When it is necessary to replace the high-pressure nozzle 2131 in the cleaning device body 2101, only need to normally control the cleaning device body 2101 to move along the filter press body 1, so that the cleaning device body 2101 moves to the front of the baffle 2114. It should be understood here that the baffle 2114 can divide the filter press body 1 into two parts of space. The space behind the baffle 2114 is the placement space for filter plates and filter meshes. Therefore, it means that when the cleaning device body 2101 is working normally, it will not move into the space in front of the baffle 2114. Only when replacing the high-pressure nozzle 2131 and the second blade 308 will the cleaning device body 2101 move into the space in front of the baffle 2114. And during the movement of the cleaning device body 2101, it is necessary to control the hydraulic device in the cleaning device body 2101 to push the lifting water spray pipe 2130 and the high-pressure nozzle 2131 to move downward, so that the high-pressure nozzle 2131 is at the same height as the disassembly cylinder 2123. During the movement of the cleaning device body 2101, the magnet block 2109 will first contact the surface of the filter press body 1, and the magnet block 2109 will be adsorbed on the surface of the filter press body 1. And the elastic potential energy of the second force spring 2126 fixed to the back of the magnet block 2109 is greater than that of the first force spring 2108. Therefore, the magnet block 2109 will push the first rectangular plate 2106 and the second rectangular plate 2105 to squeeze the first force spring 2108, so that the first rectangular plate 2106 and the second rectangular plate 2105 move backward. At this time, the high-pressure nozzle 2131 will enter the inside of the disassembly cylinder 2123 rotatably connected to the inner wall of the second rectangular plate 2105. As the cleaning device body 2101 continues to move, the second rectangular plate 2105 will be in close contact with the high-pressure nozzle 2131 to be disassembled. At this time, the second rectangular plate 2105 cannot continue to move backward. So the second force spring 2126 will start to be squeezed and contracted. Therefore, the magnet block 2109 will gradually enter the inside of the rectangular frame 2110. As the cleaning device body 2101 continues to move, the second spiral shaft 2103 will also contact the back of the lifting block 2207, thus pushing the second spiral shaft 2103 to move into the inside of the second spiral cylinder 2128. It should be understood here that the spiral groove opened on the inner wall of the second spiral cylinder 2128 corresponds to the spiral strip fixed to the surface of the second spiral shaft 2103, such as Figure 13As shown, and the second helical cylinder 2128 can rotate. Therefore, as the second helical shaft 2103 slides, it will drive the second helical cylinder 2128 to rotate. When the second helical cylinder 2128 rotates, it will transmit power to the second gear 2121, and then can drive the second toothed belt 2120 to rotate. Further, the power will be transmitted to the other four second gears 2121 through the second toothed belt 2120, thereby driving the disassembly cylinder 2123 to rotate counterclockwise. At this time, the high-pressure nozzle 2131 to be disassembled is inside the disassembly cylinder 2123. Therefore, the counterclockwise rotation of the disassembly cylinder 2123 will drive the high-pressure nozzle 2131 to rotate counterclockwise as well, and the high-pressure nozzle 2131 can be unscrewed from the surface of the lifting spray water pipe 2130. It should be understood here that a layer of rubber covers the inner wall of the disassembly cylinder 2123, and the characteristic of the large friction coefficient of the rubber can be used to increase the friction force with the high-pressure nozzle 2131. At this time, the disassembly of the high-pressure nozzle 2131 is completed. Then, control the cleaning device body 2101 to move backward a certain distance. However, since the magnet block 2109 is adsorbed on one side of the filter press body 1, the magnet block 2109 will drive the first rectangular plate 2106 and the second rectangular plate 2105 to stay in place without moving along with the movement of the cleaning device body 2101 until the water spraying end of the lifting spray water pipe 2130 is withdrawn from the inside of the disassembly cylinder 2123. Subsequently, control the hydraulic mechanism in the cleaning device body 2101 to drive the lifting spray water pipe 2130 to move upward until the water spraying end is at the same horizontal plane as the storage cylinder 2117. Then, control the cleaning device body 2101 to move forward again and repeat the above operations. Eventually, it will squeeze the first helical shaft 2102 to move. It should be understood here that when the cleaning device body 2101 moves forward for the first time, the first helical shaft 2102 will move above the lifting block 2207, and the second helical shaft 2103 will contact the upper half of the lifting block 2207. Therefore, when the cleaning device body 2101 moves forward, the second helical shaft 2103 will be pushed to move, while the first helical shaft 2102 will not be pushed at all. When the cleaning device body 2101 moves backward for the first time, it will transmit power to the automatic unloading unit 22, and eventually control the lifting block 2207 to move upward so that the upper half of the lifting block 2207 is at the same horizontal plane as the first helical shaft 2102, and the circular opening formed on the front surface of the lifting block 2207 is at the same horizontal plane as the second helical shaft 2103. Therefore, when the cleaning device body 2101 moves forward for the second time, it will drive the first helical shaft 2102 to move, and ultimately drive the storage cylinder 2117 to rotate. It should be understood here that when the cleaning device body 2101 moves forward for the second time, the water spraying end of the lifting spray water pipe 2130 is inside the storage cylinder 2117 and contacts the nozzle to be replaced inside the storage cylinder 2117. Therefore, when the storage cylinder 2117 rotates, it will tighten the nozzle on the lifting spray water pipe 2130, and multiple new high-pressure nozzles 2131 can be placed inside the storage cylinder 2117.Therefore, it can be used for the cleaning device body 2101 to complete multiple replacement operations. After the replacement is completed, the cleaning device body 2101 moves backward for the second time until it is reset.

[0030] Embodiment 2: Please refer to Figures 10-12 , the present invention provides a technical solution: a filter plate cleaning device for a plate and frame filter press. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The nozzle disassembly mechanism 2 further includes an automatic unloading unit 22. The automatic unloading unit 22 is arranged on the left side of the filter press body 1. The automatic unloading unit 22 cooperates with the disassembly unit 21, and the disassembly unit 21 ejects the used nozzle to the ground.

[0031] As a further limitation of the present invention, the automatic unloading unit 22 includes two first toothed plates 2201. The mutually close side surfaces of the two first toothed plates 2201 are respectively fixedly connected to the two side surfaces of the cleaning device body 2101. Both side surfaces of the filter press body 1 are fixedly connected with first fixing blocks 2202. A rotating shaft 2204 is rotatably connected to the inner wall of the first fixing block 2202. A transmission gear 2203 is fixedly connected to the outer surface of the rotating shaft 2204. Both side surfaces of the filter press body 1 are fixedly connected with second fixing blocks 2206. A reciprocating screw 2209 is rotatably connected to the inner wall of the second fixing block 2206. A magnetic coupling 2205 is fixedly connected to the outer surfaces of the reciprocating screw 2209 and the rotating shaft 2204. A reciprocating block 2210 is slidably connected to the inside of the reciprocating screw 2209. A lifting block 2207 is fixedly connected to the outer surface of the reciprocating block 2210. The mutually close side surfaces of the two lifting blocks 2207 are respectively in contact with the two side surfaces of the filter press body 1. An extrusion plate 2208 is fixedly connected to the front surfaces of the two lifting blocks 2207. Four round shafts 2111 are slidably connected to the inside of the filter press body 1. The ends of the four round shafts 2111 away from the cleaning device body 2101 are jointly fixedly connected with a long plate 2113. Four first return springs 2112 are fixedly connected to the back surface of the long plate 2113. The ends of the first return springs 2112 away from the long plate 2113 are fixedly connected to the front surface of the filter press body 1. By setting the automatic unloading unit 22, the used high-pressure nozzle 2131 that has been replaced can be ejected by the automatic unloading unit 22 until the high-pressure nozzle 2131 falls into the inside of the collection box 2116. It only needs to regularly process the waste high-pressure nozzles 2131 collected inside the collection box 2116.

[0032] The specific implementation of this embodiment is as follows: When the cleaning device body 2101 moves forward for the first time, it will drive the first toothed plates 2201 fixed to its two side surfaces to move synchronously. The first toothed plates 2201 will eventually mesh with the transmission gear 2203, thereby driving the transmission gear 2203 to rotate. When the transmission gear 2203 rotates, it will transmit power to the rotating shaft 2204, and the rotating shaft 2204 will transmit power to the magnetic coupling 2205. However, at this time, the magnetic coupling 2205 is in a disconnected state, so the power on the rotating shaft 2204 will not be transmitted to the reciprocating screw 2209 through the magnetic coupling 2205. When the cleaning device body 2101 moves backward for the first time, the magnetic coupling 2205 will be in a connected state. Therefore, the power that the cleaning device body 2101 moves backward to drive the transmission gear 2203 and the rotating shaft 2204 will be transmitted to the reciprocating screw 2209 through the magnetic coupling 2205. The rotation of the reciprocating screw 2209 will cause the lifting block 2207 inside to move upward along the guiding groove formed on the surface of the reciprocating screw 2209, and finally drive the lifting block 2207 to move upward. The upward movement of the lifting block 2207 will drive the pressing plate 2208 to move upward until the pressing plate 2208 contacts the surfaces of the four round shafts 2111. At this time, a thrust can be provided to the round shafts 2111, and a layer of rubber is covered on the surface of the pressing plate 2208. The characteristic of the large friction coefficient of the rubber can increase the resistance when the round shafts 2111 move forward, thereby preventing the round shafts 2111 from moving forward. When the cleaning device body 2101 moves forward for the second time, the round shafts 2111 will enter the inside of the disassembly cylinder 2123 through the circular holes 2122 formed at one end of the second gear 2121, and push out the high-pressure nozzles 2131 that have been disassembled inside the disassembly cylinder 2123 until the high-pressure nozzles 2131 fall into the inside of the collection box 2116, achieving the purpose of collecting the disassembled high-pressure nozzles 2131.

[0033] Embodiment 3: Please refer to Figure 4 - Figure 6 , the present invention provides a technical solution: a filter plate cleaning device for a plate and frame filter press. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The blade disassembly mechanism 3 cooperates with the nozzle disassembly mechanism 2, and the blade disassembly mechanism 3 replaces the damaged blades.

[0034] As a further limitation of the present invention, the blade disassembly mechanism 3 includes a storage box 312. The upper surface of the storage box 312 is fixedly connected to the telescopic end of the cleaning device body 2101. A disassembly plate 301 is arranged in front of the storage box 312. The back surface of the disassembly plate 301 is in contact with the front surface of the storage box 312. A second return spring 309 is fixedly connected to the back surface of the disassembly plate 301. The ends of the two second return springs 309 close to the first rectangular plate 2106 are commonly fixedly connected to a push plate 310. Two first blades 311 and two replacement plates 306 are arranged inside the storage box 312. The outer surface of the replacement plate 306 is in contact with the outer surface of the first blade 311. The front surface of one of the first blades 311 is in contact with the back surface of the push plate 310. Four short shafts 305 are rotatably connected to the inner wall of the storage box 312. A limiting gear 307 is fixedly connected to the outer surface of the short shaft 305. A second blade 308 is arranged inside the storage box 312. The upper surface of the second blade 308 is in contact with the bottom ends of two of the limiting gears 307. The bottom surface of the second blade 308 is in contact with the top ends of the other two limiting gears 307. A fixed cylinder 304 is fixedly connected to the upper surface of the filter press body 1. A third return spring 313 is fixedly connected to the inner wall of the fixed cylinder 304. The end of the third return spring 313 close to the storage box 312 is fixedly connected to a circular shaft 302. Two second toothed plates 314 and two third toothed plates 303 are fixedly connected to the outer surface of the filter press body 1. The second toothed plates 314 are located below the third toothed plates 303. By providing the blade disassembly mechanism 3, the damaged blades can be automatically replaced by using the blade disassembly mechanism 3. By providing the disassembly unit 21, the automatic unloading unit 22 and the blade disassembly mechanism 3, the problem that the high-pressure nozzle 2131 and the blades need to be manually replaced regularly during the use of the equipment can be effectively avoided.

[0035] The specific implementation manner of this embodiment is as follows: When the cleaning device body 2101 moves forward, the cleaning device body 2101 will drive the limiting gear 307 to engage with the second tooth plate 314 and the third tooth plate 303 forward. According to the front-back engagement sequence, the two limiting gears 307 located above will rotate 90 degrees first, and the two limiting gears 307 located below will rotate 90 degrees later, so that the limiting gear 307 does not limit the second blade 308. At this time, the second blade 308 will fall into the interior of the collection box 2116. In addition, when the storage box 312 moves forward following the cleaning device body 2101, the circular shaft 302 will enter the interior of the storage box 312 and apply pressure to the push plate 310, so that the replacement plate 306 above the second blade 308 closely adheres to the interior of the storage box 312. It should be understood here that the elastic potential energy of the third return spring 313 is greater than that of the second return spring 309, so that the circular shaft 302 can apply a thrust to the push plate 310. The existence of the push plate 310 and the second return spring 309 is to keep the replacement plate 306 and the first blade 311 stored in the storage box 312 in a vertical state. When the cleaning device body 2101 moves backward for the first time, the two limiting gears 307 located below will first engage with the second tooth plate 314, so that the two limiting gears 307 located below are first reset. At this time, as the cleaning device body 2101 moves backward, the pressure applied by the circular shaft 302 to one side of the replacement plate 306 above the second blade 308 will gradually disappear, and the replacement plate 306 will fall downward until it falls on the two second tooth plates 314 located below. It should be understood here that the second gear 2121 has been reset at this time, and the protruding part of the second tooth plate 314 is directly below the replacement plate 306. As the cleaning device body 2101 moves backward, the two limiting gears 307 located above will also engage with the third tooth plate 303 and be reset, so as to limit the replacement plate 306 from above. Subsequently, the cleaning device body 2101 will move forward for the second time, and repeating the above operation will remove the replacement plate 306, and then the first blade 311 will be clamped in the working position.
