Description

Technical Field

[0001] The invention relates to the technical field of filter press separation, in particular to a linkage type separation filter press. Background Art

[0002] In some urgent sludge treatment projects, solid residue and mud water need to be separated and treated. Filter press is a commonly used separation equipment, which uses pressure to achieve solid-liquid separation. Traditional filter press types include plate and frame filter press, chamber filter press, vertical filter press, belt filter press, etc.

[0003] The patent application with application number CN202311824735.1 discloses a linked separation filter press, which includes a supporting vertical cylinder, and a plurality of passive filter press mechanisms are evenly spaced along the circumference of the middle outer side of the supporting vertical cylinder. The inner end of each of the passive filter press mechanisms is movably extended into the vertical cavity of the supporting vertical cylinder and is connected to a linked pushing mechanism.

[0016] Compared with the prior art, the present invention provides a linkage separation filter press, which has the following beneficial effects:

[0017] 1. The present invention sets a linkage separation filter press. When it is necessary to perform solid-liquid separation and filtration on muddy water containing sludge, the sludge and muddy water can be separated with the help of a centrifugal mechanism and an auxiliary mechanism, which can improve the work efficiency and meet the urgent sludge treatment needs. At the same time, the mud cake obtained in this way has a lower water content. The lower water content not only reduces the weight and volume of the mud cake, but also provides convenience for subsequent transportation and disposal, and can improve the further utilization value of the mud cake.

[0018] 2. The present invention sets a centrifugal mechanism. The second motor drives the rotating frame to rotate along the inner wall of the supporting frame through the driving wheel, thereby driving the filter frame to rotate. During the rotation, the centrifugal force generated is used to throw out the water in the sludge. The thrown-out sewage slides along the supporting frame and is discharged from the outlet pipe, while the drier mud cake inside the filter frame is discharged through the bottom of the filter frame, thereby realizing the separation of sludge and muddy water.

[0019] 3. The present invention sets an auxiliary mechanism. The first motor drives the sliding frame to move toward the bottom side of the filter frame through the rotating shaft. Then, the second extrusion block is pushed toward the inner wall of the filter frame through the second hydraulic rod. The third motor makes the rotation speed and direction of the second extrusion block consistent with the filter frame, so that the second extrusion block and the filter frame are in a relatively static state. Then, the first extrusion block and the second extrusion block are used to squeeze the sludge inside the filter frame, so as to further reduce the water content of the mud cake and improve the filtering efficiency.

[0020] 4. The present invention provides a third hydraulic rod and a fixed ring. When the rotating frame completes the centrifugal high-speed rotation operation, the third hydraulic rod pushes the fixed ring to the bottom of the filter frame. At this time, the second protrusion fixedly connected to the inner wall of the fixed ring contacts the first protrusion on the filter frame, so that the filter frame vibrates to a certain extent, thereby preventing sludge from clogging the second through hole opened on the outer surface of the filter frame.

When it is necessary to perform solid-liquid separation and filtration on the muddy water containing sludge, the sludge and the muddy water can be separated by means of the centrifugal mechanism 2 and the auxiliary mechanism 3. This can improve the work efficiency and meet the urgent sludge treatment needs. At the same time, the mud cake obtained in this way has a lower water content. The lower water content not only reduces the weight and volume of the mud cake, but also provides convenience for subsequent transportation and disposal, and can improve the further utilization value of the mud cake. It also includes:

[0034] The centrifugal mechanism 2 includes a rotating frame 201 slidably connected to the top of the support frame 101, a first through hole 202 is opened on the top outer wall of the rotating frame 201, a filter frame 212 is slidably connected to the inner wall of the rotating frame 201, a first connecting rod 203 is fixedly connected to the outer wall of the rotating frame 201, a second motor 204 is fixedly connected to the top outer wall of the rotating frame 201, an output end of the second motor 204 passes through the rotating frame 201, and is fixedly connected to a driving wheel 205, an outer surface of the driving wheel 205 is rotatably connected to the inner wall of the first groove 107, and the second motor 204 causes the rotating frame 201 to rotate along the inner wall of the support frame 101 through the driving wheel 205, thereby driving the filter frame 212 to rotate.

[0035] A first fixed block 206 is fixedly connected to the top outer wall of the rotating frame 201, a fixed frame 207 is fixedly connected to the side of the first fixed block 206 away from the rotating frame 201, a first hydraulic rod 208 is fixedly connected to the inner wall of the fixed frame 207, a second connecting frame 209 is fixedly sleeved on the top outer wall of the first hydraulic rod 208, and the second connecting frame 209 is used to improve the stability of the first hydraulic rod 208 during movement.

[0036] One end of the second connecting frame 209 away from the first hydraulic rod 208 is fixedly connected to the fixed frame 207. The output end of the first hydraulic rod 208 is fixedly connected to the first extrusion block 211.

[0038] The working principle of this embodiment is as follows: when it is necessary to perform solid-liquid separation and filtration on the muddy water containing sludge, the second motor 204 is started, and the second motor 204 causes the rotating frame 201 to rotate along the inner wall of the supporting frame 101 through the driving wheel 205. The rotation of the rotating frame 201 drives the filter frame 212 to rotate. During this rotation process, the centrifugal force generated will throw out the water in the sludge, and the sewage after being thrown out will slide along the supporting frame 101 and finally be discharged from the outlet pipe 106, while the relatively dry mud cake inside the filter frame 212 is discharged through the bottom of the filter frame 212, thereby realizing the separation of sludge and muddy water. This method can improve work efficiency and meet urgent sludge treatment needs. At the same time, due to the action of centrifugal force, the mud cake obtained in this way has a lower water content. The lower water content not only reduces the weight and volume of the mud cake, but also provides convenience for subsequent transportation and disposal, and can also improve the further utilization value of the mud cake.

[0039] Example 2: Please refer to Figure 6-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary mechanism 3 includes a sliding frame 301 slidably connected to the outer surface of the rotating shaft 105, the inner wall of the sliding frame 301 is fixedly connected with a second hydraulic rod 302, the output end of the second hydraulic rod 302 passes through the sliding frame 301, and is fixedly connected with a third motor 303, the outer surface of the third motor 303 is fixedly sleeved with a second fixed block 304, the output end of the third motor 303 passes through the second fixed block 304, and is fixedly connected with a second extrusion block 305, the third motor 303 makes the rotation speed and direction of the second extrusion block 305 consistent with the filter frame 212, so that the second extrusion block 305 and the filter frame 212 maintain a relatively static state.

[0040] A second groove 306 is formed on the outer wall of the second extrusion block 305 away from the third motor 303, and an auxiliary wheel 307 is rotatably connected to the side of the second fixed block 304 close to the second groove 306 via a rotating shaft. The auxiliary wheel 307 is used to improve the stability of the second extrusion block 305 during rotation, and the outer surface of the auxiliary wheel 307 is rotatably connected to the inner wall of the second groove 306.

[0041] A second fixed shaft 308 is fixedly connected to the outer wall of the second fixed block 304 on one side close to the third motor 303. The second fixed shaft 308 is used to improve the stability of the second fixed block 304 during movement. The outer surface of the second fixed shaft 308 is slidably connected to the inner wall of the sliding frame 301. A second spring 309 is fixedly connected to the outer wall of the second fixed block 304. The end of the second spring 309 away from the second fixed block 304 is fixedly connected to the sliding frame 301.

[0042] A third hydraulic rod 310 is fixedly connected to the inner wall of the sliding frame 301, a second connecting rod 311 is fixedly sleeved on the outer surface of the third hydraulic rod 310 on a side away from the sliding frame 301, an end of the second connecting rod 311 away from the third hydraulic rod 310 is fixedly connected to the sliding frame 301, a fixing ring 312 is fixedly connected to the output end of the third hydraulic rod 310, a second protrusion 313 is fixedly connected to the end of the fixing ring 312 away from the third hydraulic rod 310, the second protrusion 313 is slidably connected to the first protrusion 214, and causes the filter frame 212 to generate a certain vibration.

To improve the filtering efficiency, after the rotating frame 201 completes the centrifugal high-speed rotation operation, the fixing ring 312 is pushed to the bottom of the filter frame 212 by the third hydraulic rod 310.
