Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and more specifically, to a papermaking white water slurry filtration device. Background Technology

[0002] Paper is a sheet-like material used for writing, drawing, printing, packaging, etc., and is mostly made of plant fibers. As an important invention, paper has greatly facilitated the storage and exchange of information and has epoch-making significance for promoting the development of world civilization. In actual papermaking, a large amount of white water is produced. In order to avoid the loss of plant fibers in the white water, filtration equipment is now used to filter the white water pulp. In practice, it has the advantages of simple operation, stable structure and good performance.

[0003] The prior art discloses a papermaking white pulp recycling device with application number CN202120585267.7. In this utility model, the white pulp needs to be filtered by rotating a filter cylinder. A connecting cylinder is installed at the discharge end of the filter cylinder. The white pulp inside the connecting cylinder cannot be filtered. Moreover, cleaning the inner wall of the filter cylinder requires the use of a brush structure. The brush structure comes into contact with the filter cylinder for cleaning, which can easily lead to damage to the brush structure and reduce the practicality of this utility model. At the same time, the residual fibers are stirred by stirring with a stirring rod and stirring blades. There is a gap between the stirring blades and the inner wall of the stirring space, so some residual fibers cannot be fully stirred, which poses a hidden danger to the formation of pulp in this utility model.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0008] To achieve the advantages of effectively filtering white water slurry, facilitating the cleaning of blockages on the inner wall of the filter structure, and fully agitating residual fibers, the specific technical solution adopted by this utility model is as follows:

[0009] A papermaking white water slurry filtration device includes a housing and an air pump. The housing has an internal partition, with a rotating tube passing through the upper part of the partition via a bearing. An installation cover is installed on the top surface of the housing. A feed pipe is installed between the housing and the installation cover via a bearing. A filter hopper is installed between the rotating tube and the feed pipe. A control panel is installed on one side of the housing. An air storage plate is located inside the housing. Rotating cylinders pass through both sides of the housing via bearings, and connecting pipes are sleeved on the opposing sidewalls of the two sets of rotating cylinders via bearings. A discharge pipe and a feed hopper are fixedly inserted through the outer wall of the connecting pipes. Two sets of liquid outlet pipes are fixedly inserted through one side of the box, and a feeding pipe is fixedly inserted through the other side of the box. A first forward and reverse motor and a right-angle frame are installed on the upper part of the box. A first gear is fixedly sleeved on the output end of the first forward and reverse motor. A first external toothed ring is fixedly sleeved on the side wall of the feeding pipe. A first electric telescopic rod is fixedly inserted through the upper part of the right-angle frame. A connecting shaft is installed on the telescopic end of the first electric telescopic rod, and a piston sleeve is sleeved on the lower side wall of the connecting shaft. An air guide pipe is snapped into the output end of the air pump, and one end of the air guide pipe is inserted into the interior of the air storage plate. Multiple sets of high-pressure jet nozzles are installed through the surface of the air storage plate.

[0010] Furthermore, the first gear meshes with the first external gear ring.

[0011] Furthermore, a solenoid valve is provided on the side wall of the feed hopper, an inclined block is installed on the inner bottom surface of the box, a second electric telescopic rod is fixedly connected between the box and the inclined block, and a piston block is sleeved on the telescopic end of the second electric telescopic rod through a bearing, two sets of stirring plates are installed between the two sets of rotating cylinders, a second forward and reverse motor is installed on one side of the box, and a second gear is fixedly sleeved on the output end of the second forward and reverse motor, and a second external gear ring is fixedly sleeved on the side wall of the left set of rotating cylinders, and the solenoid valve, the second electric telescopic rod and the second forward and reverse motor are electrically connected to the control panel through wires.

[0012] Furthermore, the second gear meshes with the second external gear ring.

[0013] Furthermore, both sets of liquid outlet pipes and feed pipes are equipped with on / off valves on their side walls.

[0014] Furthermore, the control panel is electrically connected to the first forward and reverse motor, the first electric telescopic rod, and the air pump via wires.

[0015] Furthermore, two sets of connecting rods are installed between the partition and the sleeve.

[0016] Furthermore, a support frame is installed at the lower part of the box.

[0017] Furthermore, multiple sets of stirring blades are installed on the inner walls of the two sets of rotating cylinders.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a papermaking white water slurry filtration device, which has the following beneficial effects:

[0020] (1) This utility model adopts a rotating tube, a feed pipe, a filter hopper, and an air storage plate. In actual use of the papermaking white water slurry filtration equipment, the white water slurry can be poured into the inside of the feed pipe, and then the control panel can be used to make the first forward and reverse motor work. The output end of the first forward and reverse motor drives the first gear to rotate. Since the first gear meshes with the first external gear ring, the rotating first gear can push the first external gear ring to rotate. The rotating first external gear ring can make the filter hopper and the rotating tube rotate through the feed pipe. Using centrifugal force, the wastewater inside the filter hopper can be thrown out of the filter hopper. By opening and closing a set of on / off valves at the top, the wastewater can pass through the upper... A set of outlet pipes discharges the liquid. Using the control panel, the air pump is activated, allowing air to enter the air storage pan through the air guide pipe. The air is then ejected through multiple high-pressure jet nozzles, which blow away blockages in the filter screen bucket. After cleaning, the first electric telescopic rod is extended using the control panel. When the piston sleeve moves down and exits the rotating tube, residual fibers can enter the feed hopper through the rotating tube. Through the rotating tube, feed pipe, filter screen bucket, and air storage pan, the white water slurry can be thoroughly filtered, and the blockages on the inner wall of the filter structure can be easily cleaned, improving the practicality of the papermaking white water slurry filtration equipment.

[0021] (2) This utility model uses a rotating cylinder. As can be seen from the above operation, the residual fibers can enter the inside of the feed hopper through the rotating tube, and then polyacrylamide is added through the feeding pipe. After that, the solenoid valve is closed using the control panel, and the second forward and reverse motor is started. The output end of the second forward and reverse motor can drive the second gear to rotate. Since the second gear meshes with the second external gear ring, the rotating second gear can drive the second external gear ring to rotate. The rotating second external gear ring can drive the left set of rotating cylinders to rotate. The left set of rotating cylinders can drive the right set of rotating cylinders to rotate through two sets of stirring plates. During the rotation of the two sets of rotating drums, the residual fibers and polyacrylamide are stirred by the two sets of stirring plates and multiple sets of stirring blades, and the pulp is gradually formed. After the pulp is formed, the second electric telescopic rod is shortened using the control panel. When the piston block moves out of the inside of the discharge pipe, the pulp inside the two sets of rotating drums and the sleeve pipe can be discharged through the discharge pipe and finally fall on the inclined surface of the inclined block. Then, the opening and closing of a set of on / off valves on the lower left side can allow the pulp to be discharged through a set of liquid outlet pipes below. The rotating drums can fully stir the residual fibers, ensuring the formation of pulp in the papermaking white water pulp filtration equipment. Attached Figure Description

[0042] In one embodiment, multiple sets of stirring blades are installed on the inner walls of the two sets of rotating cylinders 8.

[0043] Working principle:

[0044] In actual use of the papermaking white pulp filtration equipment, the white pulp can be poured into the feed pipe 5. Then, using the control panel, the first forward and reverse motor 12 is activated. The output of the first forward and reverse motor 12 drives the first gear 13 to rotate. Since the first gear 13 meshes with the first external gear ring 14, the rotating first gear 13 can push the first external gear ring 14 to rotate. The rotating first external gear ring 14 can cause the filter hopper 6 and the rotating pipe 3 to rotate through the feed pipe 5. Using centrifugal force, the wastewater inside the filter hopper 6 can be thrown out of the filter hopper 6. By opening and closing the upper set of on / off valves, the wastewater can be discharged through the upper set of liquid outlet pipes 17. Using the control panel, the air pump 19 is activated, allowing air to enter the air storage tray 21 through the air guide pipe 20. The air is then ejected through multiple high-pressure jet nozzles 22, which blow away blockages in the filter hopper 6. After cleaning, the first electric telescopic rod 16 is extended using the control panel. When the piston sleeve 7 moves down out of the rotating tube 3, residual fibers can enter the feed hopper through the rotating tube 3. Through the rotating tube 3, feed pipe 5, filter hopper 6, and air storage tray 21, the white pulp can be thoroughly filtered, and the blockages on the inner wall of the filter structure can be easily cleaned, improving the usability of the papermaking white pulp filtration equipment. In terms of functionality, and based on the above operation, it can be seen that the residual fibers can enter the interior of the feed hopper through the rotating tube 3, and then polyacrylamide can be added through the feeding tube 18. After that, the solenoid valve is closed using the control panel, and the second forward and reverse motor 28 is activated. The output end of the second forward and reverse motor 28 can drive the second gear 29 to rotate. Since the second gear 29 meshes with the second external gear ring 30, the rotating second gear 29 can drive the second external gear ring 30 to rotate. The rotating second external gear ring 30 can drive the left set of rotating drums 8 to rotate. The left set of rotating drums 8 can drive the right set of rotating drums 8 to rotate through the two sets of agitator plates 27. During the rotation of the rotating drum 8, the residual fibers and polyacrylamide are stirred by two sets of stirring plates 27 and multiple sets of stirring blades, and the pulp is gradually formed. After the pulp is formed, the second electric telescopic rod 25 is shortened by using the control panel. When the piston block 26 moves out of the discharge pipe 10, the pulp inside the two sets of rotating drums 8 and sleeve pipe 9 can be discharged through the discharge pipe 10 and finally fall on the inclined surface of the inclined block 24. Then, the opening and closing of a set of opening and closing valves on the lower left side can allow the pulp to be discharged through a set of liquid outlet pipes 17 below. The rotating drum 8 can fully stir the residual fibers, which ensures the formation of pulp in the papermaking white water pulp filtration equipment.
