Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to a pulper for clean papermaking. Background Art

[0002] Pulper is one of the most commonly used pulping equipment in pulp and paper industry, mainly used to pulp boards, waste books, waste cartons, etc.

[0003] A Chinese patent with prior art authorization announcement number CN218561929U discloses a pulper with a cleaning system, which supplies water to a water supply tank by starting a water supply mechanism. High-pressure water enters each cavity and a piston tube, pushing the piston to move away from the drive tube until a scraper contacts the inner wall of the tank body. The high-pressure water washes the inner wall of the tank body for cleaning. The drive mechanism drives the drive tube to rotate, and the rotating scraper scrapes and cleans the inner wall after washing. At the same time, the water sprayed from the nozzle corresponding to the mounting plate hits the arc-shaped pit and then reflects onto the drive tube and the crushing plate to clean the drive tube and the crushing plate. Compared with manual cleaning, it is more labor-saving and saves labor.

[0004] Although the above patent can clean the inner wall of the pulping tube, it only crushes the raw materials through a single crushing plate structure, and cannot crush the raw materials efficiently. The crushing efficiency is low, and it is very easy for large pieces of raw materials to sink to the bottom and cannot be crushed, resulting in uneven crushed pulp, further reducing the efficiency of the crushing process and the quality of the pulp.

[0005] Therefore, the applicant proposes a clean papermaking pulper to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a clean pulper for papermaking.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0008] A pulping machine for clean papermaking comprises a base and a pulping cylinder installed above the base, an inner gear ring is installed on the upper part of the inner wall of the pulping cylinder, a first rotating shaft is installed in the pulping cylinder for longitudinal rotation, a spiral blade is installed on the first rotating shaft, a plurality of connecting rods are installed on the upper part of the first rotating shaft, a gear meshing with the inner teeth of the inner gear ring is rotatably installed on the bottom of the connecting rod, a second rotating shaft is installed at the bottom of the gear, a plurality of crushing blades are installed on the second rotating shaft, and a cleaning assembly is provided on the upper part of the pulping cylinder.

[0009] Furthermore, a scraper is provided at the bottom of the first rotating shaft, and the scraper is in contact with the inner wall of the pulping cylinder.

[0010] Furthermore, the cleaning assembly includes a water tank installed on a base, a water pump is installed on the water tank, a water inlet of the water pump is connected to the water tank through a first water pipe, a water outlet of the water pump is connected to an annular diversion pipe located at the upper part of the pulping tube through a second water pipe, and a plurality of nozzles are provided at the bottom of the annular diversion pipe.

[0011] Furthermore, the top of the first rotating shaft passes through the top of the pulping cylinder and is connected to the output shaft of the motor.

[0012] Furthermore, one side of the top of the pulping cylinder is connected to a feed pipe.

[0013] Furthermore, a discharge pipe is provided at the bottom of the pulping cylinder, and a discharge valve is provided on the discharge pipe.

[0014] Furthermore, the water tank is connected with a water filling port.

[0015] Furthermore, support legs are provided on both sides of the lower part of the pulping cylinder, and the support legs are installed on the base.

[0016] Furthermore, an observation window is provided on the side wall of the pulping cylinder.

[0017] Furthermore, a controller is provided on the side wall of the pulping cylinder.

[0018] Compared with the prior art, the utility model provides a clean papermaking pulper, which has the following beneficial effects:

[0019] The utility model drives the spiral blade and the connecting rod to rotate by rotating the first rotating shaft. Due to the mutual meshing action of the inner teeth of the gear and the inner gear ring, the gear drives the second rotating shaft to rotate, and then drives the crushing blade to rotate. The setting of the spiral blade drives the raw materials at the bottom of the pulping tube to move from bottom to top, and the raw materials are crushed by the crushing blade. At the same time, due to the effect of liquid flow, the raw materials will move back and forth between the spiral blade and the crushing blade. This structure can cyclically crush the raw materials inside the pulping tube for reciprocating crushing, thereby improving the efficiency and quality of the raw material crushing processing and improving the quality of pulp; the inside of the pulping tube is cleaned by arranging a cleaning component, and the inner wall of the pulping tube is cleaned by cooperating with the scraper. The inner wall is cleaned, the cleaning difficulty of the staff is reduced, and the work efficiency of the staff is improved. BRIEF DESCRIPTION OF THE DRAWINGS
