Description

[0001] The utility model belongs to the technical field of steel paper processing, and in particular relates to a slurry conveying device for steel paper base paper production. Background Art
[0002] In the production process of steel paper base paper, a sedimentation and conveying device is required to precipitate and separate the pulp with impurities, and transport the precipitated pulp to the subsequent processing location. First, the pulp containing impurities needs to be introduced into the sedimentation tank. After standing for a certain period of time, the solid particles and impurities inside the pulp begin to sink under the action of gravity. As time goes by, the heavier particles gradually settle to the bottom of the tank to form a sedimentation layer, while the relatively pure pulp is located on the upper layer. After the sedimentation is completed, the relatively pure pulp on the upper layer is transported to the subsequent processing area. However, in actual application, when the pure pulp on the upper layer is sucked out of the sedimentation tank by the pump, the water inside the sedimentation tank will flow, causing the solid impurities settled to the bottom to follow the flow of the water to the pump suction area, which in turn causes some impurity particles to exist in the transported pulp.

[0018] In this embodiment: the sedimentation tank 1 is used to settle the pulp so that the solid particle impurities in the pulp can naturally settle to the bottom of the sedimentation tank 1, while the relatively pure pulp is located in the upper layer, completing the separation of the pulp and solid impurities. The bottom of the sedimentation tank 1 is provided with a slope, so that when the solid impurities settle to the bottom of the sedimentation tank 1, they will flow to the bottom of the slope through the guidance of the slope, and the opening of the sedimentation tank 1 for sucking the internal pulp is located at the top of the slope to reduce the situation where the particle impurities move with the pulp when the pulp is sucked, and a fixed seat 11 is fixed on the top of the sedimentation tank 1, and an internal sliding limit block 12 of the fixed seat 11 is used to limit the position of the driving rod 2, driving The rod 2 can slide on the inside of the fixing seat 11, and the filter screen 21 can slide to the inside of the sedimentation tank 1, and the filter screen 21 corresponds to the position of the opening, so that the pulp will pass through the filter screen 21 when being sucked, thereby filtering the solid impurities remaining inside the pulp, and the driving rod 2 and the filter screen 21 each have two, so that during the operation, if the surface of the filter screen 21 close to the inside of the sedimentation tank 1 is full of impurities, the staff can take out the driving rod 2 and the filter screen 21, and the filter screen 21 close to the suction positioning plate 3 can continue to perform the filtering operation, and the staff will put the taken-out filter screen 21 back in place after cleaning the surface, and slide the limit block 12 to the inside of the driving rod 2, so that the driving rod 2 and the filter screen 21 can continue to be in the closed position. The suction positioning plate 3 inside the sedimentation tank 1 is used to drive the communication port 31 to move, and the communication port 31 is used to lead out the pulp inside the sedimentation tank 1. A pump compartment 32 is installed on one side of the suction positioning plate 3. The pump compartment 32 will suck the pulp on the upper layer out of the sedimentation tank 1 through suction. The staff can connect the delivery pipe with the connection port 33 in advance, so that the pulp sucked by the pump compartment 32 will be transported to the appropriate position by the connection port 33 and the pipe, and the suction positioning plate 3 can slide on the inside of the sedimentation tank 1, so that during the suction process, the suction positioning plate 3 can continuously adjust the vertical height to make the communication port 31 correspond to the pulp position, so as to ensure the suction effect of the pulp in the pump compartment 32. It also reduces the possibility that the particulate impurities at the bottom of the sedimentation tank 1 will be sucked out along with the pulp. An active frame 4 is sliding on the inner side of the sedimentation tank 1. After the sedimentation operation is completed, the staff can slide the active frame 4 vertically downward. The active frame 4 will drive the blocking plate 41 to move synchronously during movement. When the blocking plate 41 moves to a suitable position, the staff can pull the pull rod 421 to pull the traction rope 42 to pull the blocking plate 41 until the blocking plate 41 rotates, so that the blocking plate 41 can block the particulate impurities settled at the bottom of the slope of the sedimentation tank 1, thereby reducing the situation where the particulate impurities float to the top of the sedimentation tank 1 when the pulp is sucked out, thereby further reducing the possibility that the particulate impurities are attracted along with the pulp.
[0019] An extension block 13 is fixedly connected to the top of the sedimentation tank 1, and a threaded rod 14 is rotatably connected to the inside of the extension block 13; the extension block 13 fixed at the top of the sedimentation tank 1 is used to support the threaded rod 14, so that the threaded rod 14 can slide on the inside of the extension block 13, and a driving motor is installed on the top of the extension block 13, and the output end of the driving motor is connected to the threaded rod 14, so that the threaded rod 14 can continue to rotate inside the extension block 13, and the threaded rod 14 can drive the suction positioning plate 3 to move vertically through the cooperation of other components when rotating, so that the connecting port 31 opened inside the suction positioning plate 3 will move with the height of the pulp, so that under the premise of ensuring that the pulp can be sucked, the connecting port 31 can maintain a maximum distance from the particulate impurities settled to the bottom of the slope of the sedimentation tank 1, so as to reduce the possibility of particulate impurities being sucked out of the pump chamber 32 along with the pulp.
[0020] The sedimentation tank 1 is provided with an installation groove 15 and an adjustment groove 16, and the filter screen 21 and the suction positioning plate 3 slide inside the installation groove 15 and the adjustment groove 16 respectively; the sedimentation tank 1 has two installation grooves 15, and the two filter screens 21 slide into the two installation grooves 15 respectively, so that when a large amount of impurities adhere to the surface of one of the filter screens 21 and the filtering operation cannot continue, the staff can take out the filter screen 21, and the pulp will continue to be filtered by the other filter screen 21, thereby ensuring the filtering effect. After the staff cleans the surface of the taken out filter screen 21, it can slide it into the installation groove 15 again to continue filtering the pulp, so as to ensure the filtering effect while avoiding the situation where the surface of the filter screen 21 is blocked and the pulp cannot pass through. The suction positioning plate 3 slides inside the adjustment groove 16, so that the suction positioning plate 3 can slide on the inner side of the sedimentation tank 1, and then the suction positioning plate 3 and the connecting port 31 can move vertically with the height of the pulp.
[0021] An extension plate 34 is fixedly connected to the side of the suction positioning plate 3, and the threaded rod 14 is rotatably connected to the inside of the extension plate 34; the extension plate 34 fixed to the side of the suction positioning plate 3 is used to drive the suction positioning plate 3 to move, and the threaded rod 14 is rotated inside the extension plate 34, and the inside of the extension plate 34 is provided with a thread that is adapted to the outside of the threaded rod 14, so that the threaded rod 14 will drive the extension plate 34 to move vertically when it rotates, thereby achieving the purpose of driving the suction positioning plate 3 and the connecting port 31 to move vertically.
[0022] A support rod 43 is fixedly connected to the inner side of the active frame 4, and the top of the support rod 43 is fixedly connected to the limit rod 44, and the traction rope 42 passes through the limit rod 44; the support rod 43 fixed on the inner side of the active frame 4 is used to support the limit rod 44, and the traction rope 42 passes through the inside of the limit rod 44, and the pull rod 421 is located on one side of the limit rod 44, so that the pull rod 421 will be limited by the limit rod 44 to prevent the traction rope 42 from falling into the sedimentation tank 1, so that the staff can complete the sedimentation and slide the baffle plate 41 to a suitable height. The traction rope 42 can be used to pull the baffle plate 41 by pulling the pull rod 421 to make the baffle plate 41 rotate, so as to block the particulate impurities that settle to the bottom of the sedimentation tank 1.
[0023] The working principle and use process of the present invention are as follows: when the staff needs to settle the pulp, the pulp can be introduced into the sedimentation tank 1. After a certain period of stillness, the granular impurities in the pulp will settle to the bottom of the sedimentation tank 1. The bottom of the sedimentation tank 1 is an inclined surface, so that the granular impurities will move to the bottom of the inclined surface. After the sedimentation work is completed, the staff can slide the active frame 4 to make the active frame 4 drive the blocking plate 41 to move to a suitable position. Then the staff can pull the pull rod 421 to make the traction rope 42 pull the blocking plate 41 until the blocking plate 41 rotates, so that the blocking plate 41 blocks the granular impurities settled at the bottom of the inclined surface of the sedimentation tank 1, thereby reducing the situation where the granular impurities float to the top of the sedimentation tank 1 when the pulp is sucked. Then the staff can connect the conveying pipe to the connecting port 33, and start the pump inside the pump compartment 32 and the drive motor on the top of the extension block 13. The pump compartment 32 will pump the sedimentation tank 1 The pulp inside is sucked up, and during the suction process, the suction positioning plate 3 and the connecting port 31 will continue to move vertically so that the connecting port 31 corresponds to the liquid level height of the pulp, so as to maintain a maximum distance between the connecting port 31 and the particulate impurities settled to the bottom of the slope of the sedimentation tank 1 under the premise of ensuring that the pulp can be sucked up, so as to reduce the possibility of particulate impurities being sucked out of the pump chamber 32 along with the pulp, and before the pulp is sucked out through the connecting port 31, it will first pass through the filter screen 21 so that the filter screen 21 can filter the pulp and avoid particulate impurities being sucked out of the sedimentation tank 1 along with the pulp, thereby further reducing the possibility of particulate impurities being sucked out along with the pulp, and when a large amount of impurities are attached to the surface of the filter screen 21 near the sedimentation tank 1, the staff can remove the filter screen 21 and clean its surface, and during the cleaning process, the filter screen 21 close to the suction positioning plate 3 can continue to filter impurities to ensure the filtering effect of the sucked out pulp.
