Description

Technical Field

[0001] This utility model relates to the field of papermaking processing technology, specifically to a papermaking pulp residue filtration device. Background Technology

[0002] In paper pulp treatment, the efficiency and thoroughness of pulp-slag separation directly affect pulp quality and raw material utilization. Traditional filtration devices have significant limitations: firstly, using a fixed filter plate structure, the pulp is filtered only through natural gravity permeation, resulting in slow flow rates and low pulp-slag separation efficiency, making it difficult to meet the needs of mass production. Secondly, a large amount of pulp remains in the filtered waste, leading to raw material waste. With the increasing demands for cost reduction, efficiency improvement, and environmental protection in the paper industry, there is an urgent need for a pulp residue filtration device that can achieve high-efficiency filtration, deep dewatering, and convenient maintenance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a paper pulp residue filtration device, which solves the problems of low filtration efficiency and poor filtration effect of existing devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a paper pulp residue filtration device, comprising a base, the upper wall of which is connected to a bottom frame via several first springs, a drain port on one side of the bottom frame, and a vibration motor fixedly mounted at the bottom, a screen frame detachably mounted on the upper wall of the bottom frame, a screen mesh at the bottom of the screen frame, a horizontally sliding extrusion plate inside the screen frame, several liquid permeation holes on the surface of the extrusion plate, a pair of guide rails on both sides of the upper wall of the screen frame, a pair of guide blocks fixedly mounted on both sides of the extrusion plate and slidably connected to the pair of guide rails, and a positioning component between the guide blocks and the guide rails.

[0005] Preferably, the positioning component includes a through hole on the side wall of the guide block, a positioning rod is slidably inserted into the through hole, a positioning hole is provided on one side wall of the guide rail, one end of the positioning rod is inserted into the positioning hole, and a handle is installed on the other end. A second spring is installed between the handle and the guide block.

[0006] Preferably, the outer side of the screen frame is provided with a connecting frame that is fixedly connected to the upper end of the bottom frame. Locking bolts are screwed around the connecting frame. The bottom of the screen frame rests on the top of the bottom frame, and the side wall of the screen frame is provided with a lock hole for the locking bolts to be inserted.

[0007] Preferably, the base is equipped with wheels at its bottom.

[0008] Preferably, the locking bolt is a butterfly bolt structure.

[0009] Beneficial effects

[0010] This utility model provides a paper pulp residue filtration device, which has the following beneficial effects:

[0011] The vibrating motor drives the screen frame to vibrate at high frequency, which accelerates the slurry to pass through the screen and achieves filtration. Compared with the fixed filter plate, the filtration efficiency is effectively improved. During the vibration process, the slurry flows more evenly, reducing the local accumulation of residue on the screen surface. After filtration, the residue is squeezed out by manually sliding the extrusion plate, reducing raw material waste and lowering subsequent processing costs.

[0012] The extrusion plate achieves quick locking and sliding switching through the positioning component. Manual operation does not require a complex power unit, making it suitable for small-batch intermittent filtration scenarios. The screen frame and bottom frame are detachably connected by butterfly bolts, making it convenient to clean residue or replace the screen, and greatly reducing maintenance time.

[0017] Please see Figure 1-2 This utility model provides a technical solution: a paper pulp residue filtration device, including a base 1, the upper wall of the base 1 is connected to a bottom frame 3 by a plurality of first springs 2, a drain port 4 is provided on one side of the bottom frame 3, and a vibration motor 5 is fixedly provided at the bottom, a screen frame 6 is detachably installed on the upper wall of the bottom frame 3, a screen mesh 7 is provided at the bottom of the screen frame 6, a horizontally sliding extrusion plate 8 is provided inside the screen frame 6, a plurality of liquid permeation holes 9 are arranged on the surface of the extrusion plate 8, a pair of guide rails 10 are provided on both sides of the upper wall of the screen frame 6 along the transverse direction, a pair of guide blocks 11 are fixedly provided on both sides of the extrusion plate 8 and slidably connected to the pair of guide rails 10, and a positioning component is provided between the guide blocks 11 and the guide rails 10.

[0018] By adopting the above technical solution, after the slurry is poured into the screen frame 6, the vibration motor 5 drives the bottom frame 3 and the screen frame 6 to vibrate. Under the action of vibration, the slurry quickly passes through the screen 7, is collected through the drain port 4, and after filtration, the unlocked extrusion plate 8 slides along the guide rail 10 to extrude the residue on the screen 7, squeeze out the residual slurry and filter it through the screen 7; finally, the dewatered residue is left on the screen 7 for easy centralized cleaning.

[0019] In this embodiment, the positioning component includes a through hole on the side wall of the guide block 11, a positioning rod 12 is slidably inserted into the through hole, a positioning hole is provided on one side wall of the guide rail 10, one end of the positioning rod 12 is inserted into the positioning hole, and a handle 13 is installed on the other end. A second spring 14 is installed between the handle 13 and the guide block 11.

[0020] By adopting the above technical solution, during the vibration filtration stage, the positioning rod 12 is inserted into the positioning hole to fix the extrusion plate 8, so as to prevent it from shifting with vibration and interfering with the flow of slurry. When extrusion and dewatering are required, the handle 13 is pulled to make the positioning rod 12 disengage from the positioning hole, and the extrusion plate 8 is manually pushed to slide along the guide rail 10. In conjunction with the inner side wall of the screen frame 6, the residue on the screen 7 can be extruded. After completion, the handle 13 is released, and the spring resets so that the positioning rod 12 locks the extrusion plate 8 again.

[0021] In this embodiment, the screen frame 6 is further configured such that a connecting frame 15 is fixedly connected to the upper end of the bottom frame 3 on the outside of the screen frame 6, and locking bolts 16 are screwed around the connecting frame 15. The bottom of the screen frame 6 rests on the top of the bottom frame 3, and the side wall of the screen frame 6 is provided with a locking hole for the locking bolts 16 to be inserted.

[0022] By adopting the above technical solution, when installing the screen frame 6, its bottom is placed on the bottom frame 3, and the locking bolts 16 on the connecting frame 15 are tightened to insert into the locking holes of the screen frame 6 to achieve a stable connection. After filtration is completed, the screen frame 6 can be removed by loosening the bolts in the opposite direction, and the residue can be poured out or the screen 7 can be cleaned directly.

[0023] In this embodiment, the base 1 is further configured to have a walking wheel 17 at its bottom.

[0024] By adopting the above technical solutions, the walking wheels 17 enhance the mobility of the equipment.

[0025] In this embodiment, the locking bolt 16 is further configured as a wing bolt structure.

[0026] By adopting the above technical solution, the butterfly bolt design simplifies the disassembly and assembly process of the screen frame 6, requiring no tools and allowing a single person to operate independently.

[0027] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0028] Example: Select a screen 7 with an appropriate mesh size, place the screen frame 6 on the bottom frame 3, tighten the wing bolts to insert the locking bolts 16 into the lock holes for fixation, start the vibration motor 5, and pour the slurry evenly into the screen frame 6. Under the action of vibration, the slurry quickly passes through the screen 7 and flows into the collection container through the drain port 4. After the initial filtration is completed, turn off the vibration motor 5, pull the handle 13 to disengage the positioning rod 12 from the positioning hole, manually push the extrusion plate 8 to slide along the guide rail 10, cooperate with the inner wall of the screen frame 6 to extrude the residue and squeeze out the residual slurry. The slurry is collected after secondary filtration through the screen 7. After the extrusion is completed, loosen the wing bolts to remove the screen frame 6, pour the dehydrated residue into the collection device, rinse the screen 7 with clean water to clean the residual impurities, check whether the screen 7 is damaged, and replace the screen frame 6 with a new one if necessary. It is easy to use.
