Technical Field
[0001] This utility model relates to the technical field of papermaking impurity removal and washing machines, specifically a papermaking impurity removal and washing machine that is easy to clean. Background Technology
[0002] With the continuous development of the papermaking industry, the requirements for paper quality are increasing. As the main raw material for papermaking, pulp quality directly affects the performance of paper. The pulp washing machine plays a key role in the papermaking process. It can remove impurities, black liquor and other harmful substances from the pulp, improve the purity and whiteness of the pulp, and lay the foundation for producing high-quality paper.
[0003] Chinese Patent No.: CN108755221A A novel pulp washing machine for papermaking includes a pulp washing machine body, with pulp inlets on both sides of the pulp washing machine body and a pulp outlet in the middle of the top of the pulp washing machine body. The beneficial effects of the present invention are: (1) A large amount of pulp in the present invention passes through a flow stabilizer plate. When the opening of the rotating pressure roller contacts the contact sensor of the waste pulp recovery port, the filtered pulp is discharged as waste pulp for recovery, reducing the pulp residence time and the loss of black liquor, so as to protect the environment; (2) The present invention uses the spraying of the spraying device and the blowing of the high-pressure blower to compress and reduce the volume between the pressure rollers. The pulp solids obtained by the filtering of the pressure rollers are pressed, and the screw crushes the pulp solids and transports them to the pulp outlet for recovery. At the same time, the pressure is adjusted by the pressure sensor on the screw to press the pulp solids, so that the pulp solids are not easy to accumulate, greatly improving the production capacity and reducing the power consumption.
[0004] The aforementioned patent also has some defects. The first scraper may not be able to clean the pulp in some gaps and corners on the spiral, resulting in pulp residue, which affects the normal operation of the spiral and the quality of the pulp output. The spray pipe of the spray device is equipped with a brush shaft with a steel brush. Although the steel brush can clean the inside of the spray pipe, after long-term use, impurities such as pulp fibers may become entangled on the steel brush, affecting its cleaning effect. Therefore, we need to propose a papermaking impurity removal and washing pulp machine that is easy to clean. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model provides a technical solution: a papermaking impurity removal washing machine that is easy to clean, including a washing machine 1 and a washing chamber 2. The washing chamber 2 is installed inside the washing machine 1. The washing machine 1 serves as the main support of the entire washing system, integrating various components and providing physical space and support structure for washing and related operations. The washing chamber 2 is the core space where the washing process takes place, containing the pulp and providing an installation and working environment for the rotating shaft 3, cleaning components, etc., so that the washing and cleaning operations are carried out in a closed space, preventing pulp leakage and the entry of external impurities. A rotating shaft 3 is placed horizontally inside the pulp chamber 2. The interior of the rotating shaft 3 is hollow. On the one hand, the rotating shaft 3 serves as a mounting carrier for the stirring blade 12 and the rotating brush 14. By rotating itself, it drives these cleaning components to work, thereby agitating the pulp inside the pulp washing chamber 2 and cleaning the inner wall of the chamber. On the other hand, its hollow structure serves as a liquid transmission channel, connecting the injection component and the stirring blade 12, so that the liquid in the water tank 4 or the cleaning liquid tank 5 can flow into the stirring blade 12 and be sprayed out through the spray head 13 to clean the surface of the pulp washing chamber 2 and the stirring blade 12.
[0025] A liquid injection assembly for injecting liquid into the washing chamber 2 is installed on the top of the washing machine 1. One end of the injection assembly is connected to the rotating shaft 3. The injection assembly includes a water tank 4, a cleaning liquid tank 5, a water pump 6, and a first outlet pipe 7. The water tank 4 and the cleaning liquid tank 5 are both installed on the top of the washing machine 1. The inlet of the water pump 6 is connected to a second outlet pipe 8 and a third outlet pipe 9 via a three-way pipe. The outlet of the water pump 6 is connected to one end of the first outlet pipe 7. The end of the first outlet pipe 7 away from the outlet of the water pump 6 is connected to the rotating shaft 3. The end of the second outlet pipe 8 away from the inlet of the water pump 6 is connected to the cleaning liquid tank 5. The end of the third outlet pipe 9 away from the outlet of the water pump 6 is connected to the rotating shaft 3. Water tank 4 is connected, and the surfaces of the second water outlet pipe 8 and the third water outlet pipe 9 are equipped with a first valve 10 and a second valve 11. Water tank 4 stores clean water, and cleaning liquid tank 5 stores special cleaning liquid. When liquid needs to be injected, the corresponding first valve 10 is opened to control the second water outlet pipe 8 of the cleaning liquid tank 5 to the water pump 6, or the second valve 11 controls the third water outlet pipe 9 of the water tank 4 to the water pump 6. The water pump 6 is started, and the water pump 6 draws the liquid from the water tank 4 or the cleaning liquid tank 5 through the three-way pipe. After being pressurized, it is transported through the first water outlet pipe 7 to the hollow channel of the rotating shaft 3, and then flows into the interior of the stirring blade 12. Finally, it is sprayed out from the spray head 13 on the surface of the stirring blade 12 for cleaning the pulp.
[0026] The pulp washing chamber 2 is equipped with a cleaning assembly for cleaning the chamber. One end of the cleaning assembly is connected to the rotating shaft 3. The cleaning assembly includes an agitator 12, a spray head 13, and a rotating brush 14. The agitator 12 is mounted on the surface of the rotating shaft 3, and its root is connected to the hollow channel of the rotating shaft 3 via a flexible connecting pipe. The agitator 12 agitates the pulp in the pulp washing chamber 2, ensuring thorough contact and mixing between the pulp and the cleaning liquid, thus enhancing the cleaning effect. Simultaneously, as a carrier for conveying and spraying the cleaning liquid, the cleaning liquid flowing in from the rotating shaft 3 is sprayed out from the spray head 13 on its surface through its internal hollow structure, directly cleaning the pulp. The spray head 13 is mounted on the surface of the agitator 12, and the interior of the agitator 12 is hollow. The spray head 13 is connected to the agitator 12 and sprays the cleaning liquid inside the agitator 12 at a specific angle and range, cleaning the inner wall of the pulp washing chamber 2 and also the surface of the agitator 12. The washing process involves flushing, where the impact of the water flow removes impurities, ensuring that the cleaning liquid evenly covers the surfaces of the washing chamber 2 and the agitator blades 12. A rotating brush 14 is mounted on the surface of the rotating shaft 3, with its brush head in contact with the inner wall of the washing chamber 2. As the rotating shaft 3 rotates, the rotating brush 14 moves in a circular motion around its axis, its brush head tightly adhering to the inner wall of the washing chamber 2. Under the action of friction, the brush scrapes away the deposits on the inner wall. The agitator blades 12, driven by the rotating shaft 3, also move in a circular motion, ensuring the cleaning liquid is evenly distributed throughout the washing chamber 2, improving cleaning efficiency. Simultaneously, the cleaning liquid is sprayed from inside the agitator blades 12 through the spray head 13, directly acting on the inner wall of the washing chamber 2 and the surface of the agitator blades 12, flushing away impurities inside the washing chamber 2. Driven by the rotating shaft 3, the rotating brush 14 rotates in contact with the inner wall of the washing chamber 2, removing pulp and impurities adhering to the inner wall of the chamber.
[0027] The washing machine 1 is externally equipped with a power assembly for providing power. One end of the power assembly is connected to the rotating shaft 3. The power assembly includes a motor 15, a fixing block 16, and a pulley set 17. The motor 15 is mounted externally to the washing machine 1 via the fixing block 16. One end of the rotating shaft 3 is connected to the output shaft of the motor 15 via the pulley set 17. When the motor 15 is powered on, the output shaft starts to rotate. The pulley set 17 on the output shaft of the motor 15 is connected to one end of the rotating shaft 3 via a belt, transmitting the rotational motion of the motor 15 to the rotating shaft 3, thereby driving the rotating shaft 3 to rotate. The fixing block 16 is used to securely mount the motor 15 externally to the washing machine 1, ensuring the stability of the motor 15 during operation.
[0028] A controller 18 is installed on the top of the pulp washing machine 1. The controller 18 controls the operation of each component of the pulp washing machine 1. According to the preset program or the operator's instructions, it coordinates the working status of components such as the motor 15, water pump 6, first valve 10 and second valve 11 to realize the automated pulp washing process and improve pulp washing efficiency and quality. A pulp receiving box 19 is installed below the end of the rotating shaft 3 away from the pulley group 17. The pulp receiving box 19 relies on gravity. When the pulp is separated from the rotating shaft 3 or the stirring blade 12 and other components, it falls naturally into the pulp receiving box 19 under the action of gravity, thus completing the collection of pulp.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
