Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figures 1-4 A high-consistency pulp slag remover for high-grade T-paperboard production includes a body 1, a filter cylinder 2 horizontally arranged inside the body 1, an inlet pipe 3 fixedly connected to one end of the filter cylinder 2, a rotating port opened on one side of the body 1, the inlet pipe 3 being horizontally rotatably installed in the rotating port, an outlet pipe 4 fixedly connected to one side of the body 1, and electrically controlled valves installed in both the inlet pipe 3 and the outlet pipe 4 to control the opening and closing of the inlet pipe 3 and the outlet pipe 4. The filter cylinder 2 is controlled to rotate by a drive assembly.
[0022] The upper surface of the device 1 has an installation port, in which an installation plate 5 is fixedly installed. The upper surface of the installation plate 5 has a slot, in which an insert plate 6 is slidably and sealed. The bottom of the installation plate 5 is fixedly connected to multiple spray pipes 7. The front and rear surfaces of the installation plate 5 are fixedly connected to multiple suction pipes 8. Both the suction pipes 8 and the spray pipes 7 are equipped with one-way valves. The suction pipes 8 and the spray pipes 7 are made of special corrosion-resistant materials, such as titanium alloy and polytetrafluoroethylene. These materials have extremely strong chemical stability and can effectively resist the corrosion of various chemical components in the pulp, greatly extending their service life and ensuring that they can still work normally when in contact with the pulp for a long time without contaminating the pulp. The one-way valve in the suction pipe 8 is directed from the inside of the device 1 to the slot, and the one-way valve in the spray pipe 7 is directed from the slot to the inside of the device 1. The upper surface of the device 1 is provided with a pressure component for controlling the vertical reciprocating movement of the insert plate 6.
[0023] First, the pulp to be discharged is introduced into the filter cylinder 2 located inside the body 1 through the inlet pipe 3. Then, the filter cylinder 2 is rotated by the drive component to discharge the pulp. Larger impurities and particles cannot pass through the filter holes on the surface of the filter cylinder 2, and the discharged pulp will accumulate at the bottom of the body 1 through the filter holes. During this process, the insert plate 6 will move vertically back and forth in the slot under the action of the pressing component. When the insert plate 6 moves upward, the space between the bottom of the insert plate 6 and the bottom of the slot will... As the pressure increases, the pulp accumulated at the bottom of the container 1 will be drawn into the slot by multiple suction pipes 8. When the insert plate 6 moves down, the volume of the space between the bottom of the insert plate 6 and the bottom of the slot will decrease, and the pressure will increase. The pulp in the slot will be sprayed out from multiple spray pipes 7 and act on the surface of the rotating filter cylinder 2. This will backwash the pulp after it has been discharged onto the surface of the filter cylinder 2, thereby flushing out the impurities or particles that are clogging the filter holes on the surface of the filter cylinder 2, achieving the effect of cleaning the filter holes.
[0024] The drive assembly includes a drive motor 9 and a rectangular plate 10. The body 1 has an opening on the side away from the liquid inlet pipe 3. A side plate 12 is slidably and sealed inside the opening. A telescopic cylinder 11 is fixedly installed at the bottom of the body 1. The drive shaft of the telescopic cylinder 11 is fixedly connected to the side plate 12 through a connecting plate. The drive motor 9 is fixedly installed on the surface of the side plate 12, and the output shaft of the drive motor 9 passes through the side plate 12 and is fixedly connected to the rectangular plate 10. A rectangular opening 13 is opened at the end of the filter cartridge 2 away from the liquid inlet pipe 3. The rectangular plate 10 is slidably and sealed inside the rectangular opening 13.
[0025] The telescopic cylinder 11 can move the side plate 12 laterally. After the side plate 12 is sealed and slidably inserted into the through-hole, the rectangular plate 10 will also be sealed and slidably embedded in the rectangular opening 13. At this time, the drive motor 9 is started, and the output shaft of the drive motor 9 will rotate the rectangular plate 10 and the filter cylinder 2. When the slag discharge is completed, the pulp after slag discharge can be discharged from the liquid outlet pipe 4. When it is necessary to clean the impurities or particles in the filter cylinder 2, the telescopic cylinder 11 can be started to control the side plate 12 to move away from the body 1, so that the rectangular plate 10 moves out of the rectangular opening 13. After the side plate 12 moves out of the through-hole, the impurities and particles in the filter cylinder 2 can be cleaned manually. After cleaning, the telescopic cylinder 11 is started to control the side plate 12 to move closer to the body 1, and the filter cylinder 2 is rotated slightly to align the rectangular opening 13 with the rectangular plate 10 until the side plate 12 enters the through-hole and the rectangular plate 10 also enters the rectangular opening 13.
[0026] The pressure assembly includes a reciprocating screw 14, a slider 15 threaded onto the reciprocating screw 14, and a stop rod 16 fixedly mounted on the surface of the slider 15. A fixing block is fixedly mounted on the upper surface of the body 1. The reciprocating screw 14 is horizontally rotatably mounted on the surface of the fixing block. A bevel 17 is opened on the surface of the insert plate 6. One end of the stop rod 16 is slidably disposed in the bevel 17. The reciprocating screw 14 is controlled to rotate by a transmission component. The transmission component includes two sprockets 18 fixedly mounted on the inlet pipe 3 and the reciprocating screw 14 respectively, and a chain 19. The chain 19 is engaged and wound around the two sprockets 18.
[0027] When the filter cartridge 2 rotates, the inlet pipe 3 also rotates. With the cooperation of the two sprockets 18 and the chain 19, the reciprocating screw 14 rotates together with the inlet pipe 3. The slider 15, which is threaded onto the reciprocating screw 14, moves the push rod 16 laterally. One end of the push rod 16 slides in the inclined opening 17, and the surface of the push rod 16 slides in contact with the inclined wall of the inclined opening 17. Under the pressure of the push rod 16, the insert plate 6 moves vertically. The pressure of the ejected pulp can be controlled by adjusting the speed of the drive motor 9. When the output shaft speed of the drive motor 9 is faster, the vertical movement rate of the insert plate 6 is also faster, and the pressure of the pulp ejected from the spray pipe 7 is also stronger.
[0028] A filter cover 20 is fixedly connected to the outer wall of the filter cartridge 2. The size of the filter holes on the surface of the filter cover 20 is smaller than the size of the filter holes on the surface of the filter cartridge 2. A ring 21 is fixedly installed on the surface of the side plate 12 by two connecting rods. The ring 21 is sealed and slidably embedded between the filter cartridge 2 and the filter cover 20.
[0029] When the rectangular plate 10 is slidably and sealed within the rectangular opening 13, the ring 21 will also be slidably and sealed between the outer wall of the filter cylinder 2 and the inner wall of the filter cover 20. The filter cover 20 can perform secondary fine filtration of the pulp. During the centrifugal filtration process, the filter cylinder 2 first filters out larger impurities, and the filter cover 20 can further intercept smaller particles, fiber bundles or fine impurities, ensuring that the pulp entering the subsequent process is purer, effectively improving the product quality of high-grade T-board and meeting the needs of high-quality production.
[0030] In this invention, during the rotation and slag discharge process of the filter cylinder 2, the insert plate 6 will move vertically back and forth, thereby sucking up the pulp that has been discharged from the bottom of the body 1 and spraying it out from multiple spray pipes 7. The sprayed pulp will act on the surface of the rotating filter cylinder 2, flushing out the impurities or particles that are blocked in the filter holes on the surface of the filter cylinder 2. That is, the backwashing achieves the effect of cleaning the blocked filter holes without stopping the machine for cleaning.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
