Description

Technical Field

[0001] This utility model relates to the field of pulping technology, and in particular to an anti-deposition and diversion device for a long fiber pulper. Background Technology

[0002] A pulper is a device that breaks down solid materials into a fiber suspension through mechanical stirring, shearing, and hydraulic action.

[0003] Patent application publication number CN216378910U discloses a pulping device for papermaking. It includes a pulping box, a power box, a first guide plate, a second guide plate, a sleeve, a vortex guiding device, and a pulverizing device. The power box is located at the top of the pulping box, the first guide plate is located at the bottom inside the pulping box, the second guide plate is located at the top inside the pulping box, the sleeve is located inside the pulping box and connected to the second guide plate, and the vortex guiding device is located inside the pulping box. When using this patent, a motor drives a rotating shaft to rotate, and blades pulverize the pulp inside the sleeve. However, in this prior art, residue remains on the inner wall of the pulping box after pulping. This residue dehydrates and hardens on the box wall, forming fiber clumps. When a new batch of pulp enters, these clumps fall off and mix with the new pulp, resulting in uneven strength in the finished product.

[0004] In view of the existing patents, there is a need to provide an anti-deposition and diversion device for a long fiber pulper with a wall scraping function. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, which leave residues on the inner wall of the pulping tank after pulping, and the residues harden and dehydrate on the tank wall to form fiber clumps, and when a new batch of pulp enters, the clumps fall off and mix into the new pulp, resulting in uneven strength of the finished product, this utility model provides an anti-deposition and diversion device for a long fiber pulper with a wall scraping function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an anti-settling and flow guiding device for a long fiber pulper, comprising a mounting frame, an anti-settling component, a mixing cylinder, a discharge pipe, and a spiral mixing frame. The mixing cylinder is fixedly connected to the mounting frame, and the discharge pipe is connected to the mixing cylinder. The anti-settling component is mounted on the mounting frame, and the spiral mixing frame is mounted on the anti-settling component. The device also includes an annular guide rail, scrapers, stirring rods, and a rotating frame. The annular guide rail is fixedly connected inside the mixing cylinder, and four scrapers are slidably mounted on the annular guide rail. Three sets of stirring rods are fixedly connected to the scrapers, and a rotating frame is fixedly connected to the scrapers.

[0007] Optionally, it also includes a jet pipe, a jet ring, and an air supply pipe. The anti-settling component is equipped with a jet pipe, and the mixing cylinder is equipped with a jet ring. The jet ring and the jet pipe are connected by two air supply pipes.

[0008] Optionally, it also includes a filter frame, which is installed inside the mixing drum.

[0009] Optionally, it also includes limit plates, with two limit plates fixedly connected to the mounting bracket.

[0010] Optionally, the filter frame is a hollowed-out conical shape.

[0011] Optionally, a support rod is fixedly connected to the mounting bracket.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The spiral stirring frame drives the rotating frame, which forces the scraper to move in a circular motion along the annular guide rail to remove the attached residue and prevent caking and hardening.

[0013] 2. By connecting an external air pump to the jet pipe, the jet pipe delivers high-pressure gas, which is then diverted to the jet ring through two air delivery pipes. The jet ring forms an airflow at the bottom of the mixing cylinder, ensuring uniform distribution of slurry concentration and preventing blockage of the discharge pipe. Attached Figure Description

Detailed Implementation

[0018] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] Example 1: An anti-deposition and diversion device for a long fiber pulper, see reference. Figure 1 and Figure 2As shown, the assembly includes a mounting frame 1, an anti-settling component 2, a mixing drum 3, a discharge pipe 4, and a spiral mixing frame 5. The mixing drum 3 is welded to the upper part of the mounting frame 1, and the discharge pipe 4 is connected to the lower part of the mixing drum 3. The anti-settling component 2 is mounted on the mounting frame 1. The anti-settling component 2 consists of a motor, a rotating shaft, a belt, and two rotating wheels. The motor is mounted on the mounting frame 1. A rotating shaft is rotatably mounted in the middle of the mixing drum 3. Both the rotating shaft and the output shaft of the motor are equipped with rotating wheels, and belts are wound around the two rotating wheels. The anti-settling component 2 has a spiral stirring frame 5 on its rotating shaft, and also includes an annular guide rail 6, scraper 7, stirring rod 8 and rotating frame 9. The annular guide rail 6 is installed inside the stirring cylinder 3 by welding. Four scraper 7 are evenly spaced and slidably arranged on the annular guide rail 6. The scraper 7 is in contact with the stirring cylinder 3. Three sets of stirring rods 8 are evenly spaced and fixedly connected to the scraper 7. The three stirring rods 8 form a group. The rotating frame 9 is fixedly connected to the scraper 7. The rotating frame 9 is in contact with the spiral stirring frame 5.

[0020] See Figure 1 As shown, it also includes a filter frame 13, which is installed in the upper part of the mixing cylinder 3.

[0021] See Figure 1 As shown, the filter frame 13 is a hollowed-out conical shape.

[0022] See Figure 1 As shown, a support rod is fixedly connected to the mounting bracket 1, and the support rod is used to support the discharge pipe 4.

[0023] When this device is needed, first install the mounting frame 1 on the designated equipment so that the discharge pipe 4 is connected to the corresponding external connecting pipe. Then start the motor on the anti-settling component 2. The motor drives the rotating shaft to rotate through two wheels and a belt. The rotating shaft drives the spiral mixing frame 5 to push the slurry axially to prevent bottom sedimentation and fiber clumping. At the same time, the spiral mixing frame 5 pushes the rotating frame 9, forcing the scraper 7 to move in a circle along the annular guide rail 6 to remove the attached residue and prevent agglomeration and hardening. The filter frame 13 filters and screens the slurry.

[0024] Example 2: Based on Example 1, refer to Figure 1 and Figure 3 As shown, it also includes a jet pipe 10, a jet ring 11, and an air supply pipe 12. The lower part of the rotating shaft of the anti-settling component 2 is fitted with a jet pipe 10. The jet pipe 10 passes through the mixing cylinder 3. The mixing cylinder 3 is connected to the jet pipe 10. A jet ring 11 is provided inside the mixing cylinder 3. Two air supply pipes 12 are connected to the jet ring 11 and the jet pipe 10. The air supply pipes 12 pass through the mixing cylinder 3. The jet pipe 10 is connected to an external air pump.

[0025] See Figure 1As shown, it also includes limit plates 14. Two limit plates 14 are provided on the mounting frame 1 by means of bolt connection, and two gas supply pipes 12 pass through the two limit plates 14.

[0026] While guiding the flow, an external air pump is connected to the jet pipe 10, which delivers high-pressure gas. The gas is then diverted to the jet ring 11 via two air delivery pipes 12. The jet ring 11 forms an airflow at the bottom of the mixing drum 3, which makes the slurry concentration evenly distributed and prevents the discharge pipe 4 from being blocked. The limiting plate 14 fixes the air delivery pipe 12 to prevent airflow pulsation from causing pipe vibration.
