Description

Technical Field

[0001] This application relates to the technical field of paper pulp residue cleaning and removal, and in particular to a paper pulp residue cleaning and removal device. Background Technology

[0002] With the improvement of people's living standards, the rise of online shopping and the rapid development of the logistics industry, people's demand for packaging paper is increasing, and waste paper recycling is the most environmentally friendly papermaking method.

[0003] The primary pulp residue generated during waste paper recycling and papermaking often contains some fibers. Traditional methods involve directly filtering the pulp through a filter screen to prevent this, but fibers accumulate on the screen surface. Workers need to clean the screen regularly to minimize fiber interference with pulp flow and reduce production efficiency. Since the pulp typically flows quickly in the pool, continuous cleaning is necessary, making the work quite strenuous. Therefore, those skilled in the art have provided a paper pulp residue cleaning and impurity removal device to address the problems mentioned in the background section. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a paper pulp residue cleaning and impurity removal device.

[0005] The paper pulp residue cleaning and impurity removal device provided in this application adopts the following technical solution:

[0006] A paper pulp residue cleaning and impurity removal device includes a flow tank, an inlet pipe fixedly inserted into one side of the flow tank, an outlet pipe fixedly inserted into the other side of the flow tank, and a filter screen installed inside the outlet pipe.

[0007] A motor is located on one side of the middle of the flow tank. A rotating shaft is fixedly connected to one output end of the motor. A claw assembly is sleeved on the surface of the rotating shaft. The claw assembly rotates inside the flow tank.

[0008] A material collection plate is disposed on the flow pool and located on one side of the hook assembly. A receiving plate is disposed above the material collection plate, and drain pipes are inserted into both sides of the material collection plate.

[0009] In some embodiments, the outlet pipe is fixedly connected to a sleeve inside the flow tank, a support ring is fixedly connected to the outer wall of the filter screen, and a threaded tube is provided in the middle of the filter screen, the surface of the threaded tube engaging with the threaded sleeve.

[0010] In some embodiments, the hook assembly includes a rotating column fixed to the surface of the rotating shaft, and hook plates are fixedly connected to the surface of the rotating column at equal intervals in a ring, the hook plates being inclined toward the side closer to the water inlet pipe.

[0011] In some embodiments, a receiving platform is fixedly connected to one side of the receiving plate, the receiving platform is tilted upward, and the receiving platform and the claw plate are arranged alternately.

[0012] In some embodiments, the receiving plate has drainage grooves inside, and there are multiple drainage grooves located above the collecting plate.

[0013] In some embodiments, a baffle is fixedly connected to the side of the receiving plate away from the receiving platform, and the two sides of the baffle are in contact with the inner wall of the collecting plate.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] (1) When it is necessary to remove fibers from pulp slag water, workers inject pulp slag water into the flow tank through the water inlet pipe. When the pulp slag water passes through the flow tank, the motor drives the output shaft to rotate. The shaft drives the hook assembly to rotate inside the flow tank. The hook assembly will retrieve the fibers inside the flow tank. The hook assembly will transfer the retrieved limit to the top of the receiving plate. The receiving plate will slide the limit into the collection plate. The collection plate will drain the water through the drain pipes on both sides and then collect the fibers. The continuous rotation of the hook assembly replaces manual labor, improving the retrieval efficiency of fibers inside the flow tank and reducing the labor intensity of workers.

[0016] (2) During the rotation of the hook plate, it will come into contact with the receiving platform. The fibers on the surface of the hook plate will slide onto the surface of the receiving platform. The fibers will slide on the surface of the receiving platform. By the tilt angle of the receiving platform, the flow through the receiving platform to the surface of the receiving plate is limited. After the hook plate passes through the receiving platform, the debris on the surface will be removed, reducing the fibers from tangling on the surface of the hook plate and facilitating subsequent cleaning of the hook plate surface.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a paper pulp residue cleaning and impurity removal device. (Refer to...) Figure 1-4 A paper pulp residue cleaning and impurity removal device includes a flow tank 1, a motor 5, and a collection plate 8. A water inlet pipe 2 is fixedly inserted into one side of the flow tank 1, and a water outlet pipe 3 is fixedly inserted into the other side of the flow tank 1. A filter screen 4 is installed inside the water outlet pipe 3. The motor 5 is located in the middle of the flow tank 1. A rotating shaft 6 is fixedly connected to one output end of the motor 5. A hook assembly 7 is sleeved on the surface of the rotating shaft 6. The hook assembly 7 rotates inside the flow tank 1. The collection plate 8 is installed on the flow tank 1 and located on one side of the hook assembly 7. A receiving plate 9 is installed above the collection plate 8. Drainage pipes 81 are inserted into both sides of the collection plate 8.

[0024] In this way, when it is necessary to remove fibers from the pulp residue water, the worker injects pulp residue water into the flow tank 1 through the water inlet pipe 2. When the pulp residue water passes through the flow tank 1, the motor 5 drives the output shaft 6 to rotate. The shaft 6 drives the hook assembly 7 to rotate inside the flow tank 1. The hook assembly 7 will retrieve the fibers inside the flow tank 1. The hook assembly 7 will transfer the retrieved limit to the top of the receiving plate 9. The receiving plate 9 will slide the limit into the collection plate 8. The collection plate 8 will drain the water through the drain pipes 81 on both sides and then collect the fibers.

[0025] After being scooped out inside the flow tank 1, the pulp water flows through the hook assembly 7 and the collection plate 8, and then flows out through the outlet pipe 3. When the pulp water flows into the outlet pipe 3, the filter screen 4 blocks the fibers, reducing the outflow of fibers. The filter screen 4 protrudes outward from the outlet pipe 3, and the water flows out through the filter screen 4. The subsequent water flow will flow through both sides of the filter screen 4. During the flow, the water washes the fibers on the surface of the filter screen 4, reducing the clogging of the filter screen 4 surface by the fibers. The fibers will flow back into the flow tank 1. When they are confined to the flow tank 1, they will be scooped out by the hook assembly 7, increasing the fiber cleaning efficiency.

[0026] Among them, the water outlet pipe 3 is fixedly connected to the sleeve 31 inside the flow pool 1, the outer wall of the filter screen 4 is fixedly connected to the support ring 41, and the middle part of the filter screen 4 is provided with a threaded pipe 42, the surface of the threaded pipe 42 is threadedly engaged with the sleeve 31.

[0027] The filter screen 4 has a ring-shaped hollow structure. The filter screen 4 can block the water flow and limit the flow. Water flows through the perimeter and inside of the filter screen 4. The sleeve 31 has threads inside and engages with the threaded tube 42 to fix the filter screen 4 inside the outlet pipe 3. The support ring 41 increases the external structural strength of the filter screen 4, reduces the filter screen 4's resistance to water pressure, and increases the structural strength of the filter screen 4.

[0028] Preferably, the hook assembly 7 includes a rotating column 71 fixed to the surface of the rotating shaft 6. Hook plates 72 are fixedly connected to the surface of the rotating column 71 at equal intervals in a ring. The hook plates 72 are inclined towards the side closer to the water inlet pipe 2. A locking block is installed on the surface of the rotating shaft 6. The locking block on the surface of the rotating shaft 6 slides and engages with the inner wall of the rotating column 71, so that the rotating column 71 rotates with the rotating shaft 6. During the rotation of the rotating column 71, the hook plates 72 slide inside the flow tank 1. The hook plates 72 have a certain tilt angle, which can pick up the fibers in the water. A water passage groove is opened on the surface of the hook plates 72, and water will flow through the inside of the hook plates 72, reducing the impact of water pressure on the hook plates 72 and improving the rotation efficiency of the hook plates 72.

[0029] Specifically, a receiving platform 91 is fixedly connected to one side of the receiving plate 9. The receiving platform 91 is tilted upwards and is staggered with the hook plate 72. During the rotation of the hook plate 72, it will come into contact with the receiving platform 91. The fibers on the surface of the hook plate 72 will slide onto the surface of the receiving platform 91. The fibers will slide on the surface of the receiving platform 91. Through the tilt angle of the receiving platform 91, the fibers will flow through the receiving platform 91 to the surface of the receiving plate 9. After the hook plate 72 passes through the receiving platform 91, the debris on the surface will be removed, reducing the fibers from wrapping around the surface of the hook plate 72 and facilitating the subsequent cleaning of the surface of the hook plate 72.

[0030] More specifically, the receiving plate 9 has multiple drainage grooves 93 inside. These drainage grooves 93 are located above the collecting plate 8 and at the bottom of the receiving plate 9. When fibers accumulate on the surface of the receiving plate 9, the water on the fiber surface will flow into the interior of the collecting plate 8 through the drainage grooves 93, reducing the pressure of the fibers on the surface of the receiving plate 9. The upper surface of the receiving plate 9 is open, making it convenient for workers to clean the fibers on the surface.

[0031] Furthermore, during implementation, a baffle 92 is fixedly connected to the side of the receiving plate 9 away from the receiving platform 91. The two sides of the baffle 92 are in contact with the inner wall of the collecting plate 8. The baffle 92 will block one side of the receiving plate 9, preventing the fibers from flowing into the interior of the collecting plate 8. The baffle 92 increases the structural strength of the connection between the receiving plate 9 and the receiving platform 91 and the collecting plate 8, and increases the structural strength of the receiving plate 9 and the receiving platform 91.

[0032] The implementation principle of the paper pulp residue cleaning and impurity removal device in this embodiment is as follows: When it is necessary to remove fibers from the pulp residue water, the worker injects the pulp residue water into the flow tank 1 through the water inlet pipe 2. When the pulp residue water passes through the flow tank 1, the motor 5 drives the output shaft 6 to rotate. The shaft 6 drives the hook assembly 7 to rotate inside the flow tank 1. The hook assembly 7 will retrieve the fibers inside the flow tank 1. The hook assembly 7 will transfer the retrieved limit to the top of the receiving plate 9. The receiving plate 9 will slide the limit into the collection plate 8. The collection plate 8 will drain the water through the drain pipes 81 on both sides, and then collect the fibers. After being collected inside the flow tank 1, the pulp water flows through the hook assembly 7 and the collecting plate 8, and then flows out through the outlet pipe 3. When the pulp water flows into the outlet pipe 3, the filter screen 4 blocks the fibers, reducing the outflow of fibers. The filter screen 4 protrudes outward from the outlet pipe 3, and the water flows out through the filter screen 4. The subsequent water flow flows through both sides of the filter screen 4. During the flow, the water washes the fibers on the surface of the filter screen 4, reducing the clogging of the filter screen 4 surface. The fibers will flow back into the flow tank 1. When they are confined to the flow tank 1, they will be picked up by the hook assembly 7, increasing the fiber cleaning efficiency.
