Description

Technical Field

[0001] This utility model relates to the field of pulp production technology, and in particular to a high-consistency pulper. Background Technology

[0002] High-consistency hydraulic pulpers are mainly used in the deinking process of waste paper. They break down waste paper under high concentration and water temperature conditions of 60-90℃. At the same time, through the action of chemicals, ink particles and fibers are separated. High-consistency hydraulic pulpers have become one of the indispensable core equipment in the waste paper deinking pulping process. The rotor structure of high-consistency hydraulic pulpers is usually a spiral blade structure, which has a powerful breaking down effect.

[0003] Chinese Patent CN221918745U discloses a high-consistency pulper rotor structure, including a pulper tank and a rotor assembly installed inside the pulper tank. A drive motor is fixedly installed at the bottom of the pulper tank, and a feed inlet is opened at the top of the pulper tank. An installation assembly is provided between the rotor assembly and the pulper tank. The rotor assembly includes a rotating cylinder located inside the pulper tank and helical blades fixedly installed outside the rotating cylinder. The installation assembly includes a mounting plate fixedly installed on the output shaft of the drive motor and a first rectangular block fixed on the mounting plate. This high-consistency pulper rotor structure allows for quick disassembly of the rotor assembly from inside the pulper tank by simply removing the mounting plate above the feed inlet when cleaning the helical blades. The structure is simple, easy to clean and maintain, and provides convenience for cleaning work.

[0004] However, the above technical solution has the following shortcomings: When the pulp is discharged during the pulping process, the pulp is pushed out of the pulper by the rotor, but at the end of the pulping process, some pulp will remain in places that the rotor cannot reach, which requires workers to clean it. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a high-concentration pulper that directly pushes the pulp to the vicinity of the discharge component by setting a separator and a pusher, and then the discharge component transports the pulp out of the machine, thereby reducing the amount of pulp remaining in the machine after production.

[0006] The technical solution of this utility model is a high-consistency pulper, comprising: a tank body with a motor mounted on its top and a rotor mounted on the motor output end; a separator frame detachably mounted on the tank body, and a pusher frame rotatably mounted on the separator frame and the tank body, the pusher frame including a connecting disc coaxially connected to the rotor, and multiple pusher rods arranged circumferentially on the connecting disc; one end face of each of the multiple pusher rods gradually tilts towards the end away from the direction of rotation according to the distance between them and the connecting disc; and a discharge assembly connected to the tank body.

[0007] Preferably, the separator has an inclined annular surface and a plurality of discharge holes distributed along the annular surface, with each discharge hole located on the annular surface.

[0008] Preferably, the top of the tank is hinged to two sets of sealing components. The sealing components include a sealing plate hinged to the top of the tank, an arc plate hinged to the sealing plate, and bolts provided on the sealing plate and the arc plate.

[0009] Preferably, the discharge assembly includes a mounting bracket detachably mounted on the tank body, a guide pipe mounted on the mounting bracket, a threaded rod slidably mounted on the guide pipe, a sealing plate mounted on the threaded rod, and a conveying assembly mounted on the guide pipe.

[0010] Preferably, the sealing plate and the push rod make slidable contact.

[0011] Preferably, the material conveying assembly includes a drive frame mounted on the guide pipe, a motor mounted on the drive frame, a drive roller mounted on the motor output end, a rotating spiral conveyor rod mounted on the guide pipe and the drive frame, a driven roller mounted on the spiral conveyor rod, and a transmission belt mounted on the drive roller and the driven roller.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In use, the user pours paper, water at the required temperature, and chemicals into the tank. The motor drives the rotor to process the paper into the desired shape. The paper then passes through a separator and moves between the separator and the tank. The rotor, via a connecting disc, drives multiple push rods to push the pulp to the edge of the tank. The inclined surfaces of the push rods are distributed in the direction of rotation, creating uneven force on the pulp moving towards the edge. Once a certain amount of pulp is collected, the user opens the discharge assembly to drain the pulp, reducing residual pulp inside the tank. During the next pulping process, water and chemicals soften and discharge any remaining pulp, reducing the frequency of cleaning by workers. Attached Figure Description

[0018] Example 1

[0019] like Figures 1-3 As shown, the high-consistency pulper proposed in this embodiment includes a tank 1, a separator 8, and a discharge assembly. A motor 4 is installed at the top of the tank 1, and a rotor 5 is installed at the output end of the motor 4. The separator 8 is detachably installed on the tank 1, and a pusher 6 is rotatably installed on the separator 8 and the tank 1. The pusher 6 includes a connecting plate portion coaxially connected to the rotor 5, and multiple pusher rod portions arranged in a ring on the connecting plate portion. One end face of each of the multiple pusher rod portions gradually tilts towards the end away from the rotation direction according to the distance between it and the connecting plate portion. The discharge assembly 7 is connected to the tank 1.

[0020] In this embodiment, the user pours paper, water at the required temperature, and chemicals into the tank 1. Then, the motor 4 drives the rotor 5 to process the paper into the shape required by the user. The paper then passes through the separator 8 and moves to the space between the separator 8 and the tank 1. The rotor 5 then drives multiple push rods via the connecting plate to push the pulp to the edge inside the tank 1. The inclined surfaces of the push rods are distributed in the direction of rotation to make the force on the pulp moving on the push rods uneven, thus causing the pulp to move towards the edge. After the amount of pulp reaches a certain quantity, the user opens the discharge assembly 7 to discharge the pulp, thereby reducing the amount of pulp remaining inside the tank. In the next pulping process, water and chemicals will soften and discharge the remaining pulp, thereby reducing the number of cleaning operations required by the workers.

[0021] Example 2

[0022] like Figure 1 and Figure 2 As shown, the high-consistency pulper proposed in this embodiment, compared with Embodiment 1, has a partition frame 8 with an inclined annular surface 81. The partition frame 8 also has multiple discharge holes distributed along the annular surface, with each discharge hole located on the annular surface. Two sets of sealing assemblies are hinged to the top of the tank body 1. The sealing assemblies include a sealing plate 2 hinged to the top of the tank body 1, an arc-shaped plate 3 hinged to the sealing plate 2, and bolts installed on the sealing plate 2 and the arc-shaped plate 3.

[0023] In this embodiment, the pulp that meets the requirements will move through the discharge hole to the space between the tank 1 and the separator 8. The rotor 5 occupies the entire bottom end face of the separator 8 to push all the pulp. After the user pours in the shredded paper, he closes the sealing component to allow the shredded paper inside the tank 1 to fully react with the chemicals at a suitable temperature.

[0024] Example 3

[0025] like Figures 1-3 As shown, the high-consistency pulper proposed in this embodiment, compared with Embodiment 1, includes a discharge assembly 7 comprising a mounting bracket 71 detachably mounted on the tank body 1, a guide pipe 72 mounted on the mounting bracket 71, a threaded rod 74 slidably mounted on the guide pipe 72, a sealing plate 73 mounted on the threaded rod 74, and a conveying assembly mounted on the guide pipe 72. The sealing plate 73 is in slidable contact with the push rod.

[0026] The material conveying assembly includes a drive frame 75 mounted on the guide pipe 72, a motor 76 mounted on the drive frame 75, a drive roller 77 mounted on the output end of the motor 76, a spiral conveying rod rotatably mounted on the guide pipe 72 and the drive frame 75, a driven roller 78 mounted on the spiral conveying rod, and a transmission belt mounted on the drive roller 77 and the driven roller 78.

[0027] In this embodiment, the user rotates the bolts threaded onto the threaded rod 74 and then adjusts the position of the sealing plate 73 until the sealing plate 73 no longer contacts the push rod. Then, the motor 76 drives the spiral conveyor rod through the transmission belt to convey the pulp out of the machine, thereby increasing the output speed of the pulp.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
