Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulp technology, and in particular to a slag removal device for papermaking. Background Technology
[0002] Pulp is a fibrous material made from plant fibers through different processing methods. It can be classified into mechanical pulp, chemical pulp, and chemimechanical pulp according to the processing method, or into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc., according to the fiber raw materials used. Pulp needs to undergo a deslagging process to improve the smoothness of the paper.
[0003] When existing dedicated slag removal devices are in use, the filter screen is usually fixedly connected to the machine body when the slurry is filtered by the screen, resulting in slow slag filtration and poor practicality. Utility Model Content
[0004] This utility model proposes a slag removal device for papermaking.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A slag removal device for papermaking includes a base, on which a first side plate and a second side plate are fixedly installed. A slag removal box is fixedly installed on the first side plate. A sleeve and a motor are fixedly installed on both sides of the second side plate, respectively. A rotating shaft is rotatably installed inside the sleeve. One end of the rotating shaft passes through the slag removal box and is fixedly connected to a crushing roller. A driven gear is fixedly installed on the other end of the rotating shaft. A connecting rod is rotatably installed outside the rotating shaft. A filter box is fixedly installed at the bottom of the connecting rod. The output shaft of the motor passes through the side plate and is fixedly connected to a transmission plate. The transmission plate is rotatably connected to the upper middle part of the connecting rod through a pull rod. A driving gear is fixedly installed on the output shaft of the motor. The driving gear meshes with the driven gear for transmission.
[0007] A further preferred embodiment of this utility model is as follows: a filter port is provided at the bottom of the slag removal box, the filter port is always located at the top of the filter box, and the sieve holes on the filter port are larger than the sieve holes inside the filter box.
[0008] A further preferred embodiment of this utility model is that the sleeve is positioned higher than the motor, and the motor output shaft is located on the lower side of the sleeve.
[0009] A further preferred embodiment of this utility model is that a collection box is installed on the base, and the bottom of the filter box is always located at the top of the collection box.
[0010] The present invention has the following advantages:
[0011] 1. This utility model uses a motor to drive the active gear to rotate the driven gear, which enables the crushing roller to break up the pulp in the pulp removal box and perform preliminary filtration of the pulp, thus increasing the practicality of the device.
[0012] 2. This utility model uses a motor-driven transmission plate to drive a pull rod to control the connecting rod to shake, thereby accelerating the filtration of pulp in the filter box and increasing the practicality of the device. Attached Figure Description

[0016] 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.
[0017] according to Figure 1-2 As shown, a slag removal device for papermaking includes a base 1, on which a first side plate 2 and a second side plate 3 are fixedly installed. A slag removal box 4 is fixedly installed on the first side plate 2. A sleeve 5 and a motor 6 are fixedly installed on both sides of the second side plate 3, respectively. A rotating shaft 7 is rotatably installed inside the sleeve 5. One end of the rotating shaft 7 passes through the slag removal box 4 and is fixedly connected to a crushing roller 15. A driven gear 9 is fixedly installed on the other end of the rotating shaft 7. A connecting rod 12 is rotatably installed outside the rotating shaft 7. A filter box 13 is fixedly installed at the bottom of the connecting rod 12. The output shaft of the motor 6 passes through the side plate and is fixedly connected to a transmission plate 10. The transmission plate 10 is rotatably connected to the upper middle part of the connecting rod 12 through a pull rod 11. A driving gear 8 is fixedly installed on the output shaft of the motor 6. The driving gear 8 meshes with the driven gear 9 for transmission.
[0018] The bottom of the slag removal box 4 is equipped with a filter port, which is always located at the top of the filter box 13. The sieve holes on the filter port are larger than the sieve holes inside the filter box 13. This arrangement ensures that the slag removal box 4 can perform preliminary filtration, and at the same time ensures that the pulp filtered out of the slag removal box 4 can fall into the filter box 13, thus ensuring the stability of the device.
[0019] The sleeve 5 is positioned higher than the motor 6, and the output shaft of the motor 6 is located on the lower side of the sleeve 5. This arrangement ensures the normal operation of the device.
[0020] A collection box 14 is installed on the base 1, and the bottom of the filter box 13 is always located on the top of the collection box 14. This arrangement ensures that all the pulp filtered out in the filter box 13 can fall into the collection box 14, thus ensuring the stability of the device.
[0021] Working principle: Motor 6 operates, and the driving gear 8 drives the driven gear 9 to rotate. The rotating shaft 7 drives the crushing roller 15 to break up the pulp in the slag removal box 4. At the same time, the slag removal box 4 filters the pulp. The initially filtered pulp falls into the filter box 13. Meanwhile, the transmission plate 10 of motor 6 drives the connecting rod 12 to swing through the pull rod 11. The filter box 13 will then swing back and forth to assist in filtration. The filtered pulp falls into the collection box 14, and the work is completed.
[0022] 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.
