Description

Technical Field

[0001] The utility model belongs to the technical field of wood pulp processing, and particularly relates to a high-strength defibrated wood pulp pulper. Background Art

[0002] High-strength defibrated wood pulp refers to wood pulp made from wood as raw material, which is classified according to pulping materials, pulping methods of defibrated wood pulp, and pulp uses, such as sulfate softwood pulp, mechanical wood pulp, refined wood pulp, etc. Classified according to beating characteristics of defibrated wood pulp, wood fibers are generally divided into two categories: softwood and hardwood. Among the same tree species, due to the different growth rates of plants in different seasons, they are also divided into early wood (spring wood) and late wood (autumn wood).

[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: At present, in the process of processing high-strength defibrated wood pulp, it involves the crushing work of its raw materials, that is, using a pulper to crush the raw materials of high-strength defibrated wood pulp. However, such a pulper usually needs to soften the raw materials of high-strength defibrated wood pulp in advance and then transport them to the pulper for crushing. Due to the two processes of softening and transportation in advance, it results in a waste of more time and a significant reduction in efficiency.

[0004] Therefore, we propose a high-strength defibrated wood pulp pulper to solve the above problems. Content of the Utility Model

[0005] The main purpose of the present utility model is to provide a high-strength defibrated wood pulp pulper, enabling the raw materials of high-strength defibrated wood pulp to quickly become soft by water and quickly undergo crushing work, thereby greatly improving the pulping efficiency of the raw materials of high-strength defibrated wood pulp and effectively solving the problems in the background art.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] A high-strength defibrated wood pulp pulper includes a pulping tank, a pulping assembly and a warming assembly located on the pulping tank. A feeding pipe is fixedly connected to the center of the top wall of the pulping tank, and a discharging pipe is fixedly connected to the center of the bottom wall of the pulping tank. The pulping assembly includes two external motors installed on one side wall of the pulping tank, inner support shafts coaxially connected to the output shafts of the two external motors respectively, and roller bodies fixedly sleeved on the two inner support shafts respectively;

[0008] On one side wall of the pulping tank, a warm liquid tank is fixed. The warming component includes a pump body installed on the warm liquid tank, an input pipe and an output pipe connected to the pump body, a long pipe fixedly connected to the output pipe, and a plurality of atomizing nozzles installed on the long pipe at equal intervals. The long pipe is located inside the pulping tank, and both sides of the long pipe are welded to the pulping tank. The plurality of atomizing nozzles are all inclined, and the inclination angle is 45°. So that the plurality of atomizing nozzles can spray misty water in an oblique direction, thereby heating and moistening the high-strength defibrated wood pulp raw material that is about to fall between the two rollers. An electric heating component is installed at the bottom of the inner cavity of the warm liquid tank, and temperature sensors are installed on both sides of the inner cavity of the warm liquid tank. A display screen and a PLC are also installed on the outer wall of the warm liquid tank. The electric heating component, the temperature sensor and the display screen are all electrically connected to the PLC.

[0009] As a preferred implementation, legs are welded at the four corners of the bottom wall of the pulping tank. The four legs are distributed in a rectangular array; so as to keep the four sides of the pulping tank stable, enabling the discharge pipe to smoothly discharge the broken high-strength defibrated wood pulp raw material. The two sides at the bottom of the inner cavity of the pulping tank are both inclined, and the inclined designs on both sides are directed towards the discharge pipe, so as to reduce the probability of the high-strength defibrated wood pulp raw material accumulating in the inner cavity of the pulping tank.

[0010] As a preferred implementation, a side support is welded on the side of the pulping tank where the warm liquid tank is located. The side support is designed in an L shape; and an inclined plate with an inclination of 45° is integrally welded on the inner side of the side support for supporting the side support, making the structures such as the warm liquid tank on it more stable.

[0011] As a preferred implementation, an adding cylinder communicating with its inner cavity is fixedly connected to one side of the top wall of the warm liquid tank; thus, water or other media that can heat the high-strength defibrated wood pulp raw material can be added into the warm liquid tank through the adding cylinder.

[0012] As a preferred implementation, the side of the input pipe away from the pump body passes through one side wall of the warm liquid tank and extends into the bottom of the inner cavity of the warm liquid tank, and the side of the output pipe away from the pump body passes through the top wall of the pulping tank; making the input pipe and the output pipe have stable structures and completing the functions of extracting one medium and releasing the other medium.

[0013] As a preferred implementation, both inner support shafts are horizontally arranged in the inner cavity of the pulping tank, and both sides of the inner support shafts are rotatably connected to the pulping tank; enabling the two inner support shafts to drive the rollers on them to operate stably. The two rollers are designed to be of the same height, and a gap is left between them for crushing the high-strength defibrated wood pulp raw material.

[0014] In summary, the technical effects and advantages of the present utility model:

[0015] This high-strength defibrated wood pulp pulper can greatly improve the pulping efficiency of high-strength defibrated wood pulp raw materials. When adding high-strength defibrated wood pulp raw materials into the feeding pipe, atomized water at a specified temperature is sprayed into the pulping tank, enabling the high-strength defibrated wood pulp raw materials to be softened by water quickly and then be pulverized rapidly.

[0016] For this high-strength defibrated wood pulp pulper, two temperature sensors monitor the medium temperature in the warm liquid tank in real time and transmit electrical signals to the PLC in real time. Then the PLC can transmit electrical signals to the display screen to show the temperature value, so that the operator can control the operation of the electric heating component after seeing the value. When the temperature is appropriate, the pump body is driven to operate, and the medium is pumped out through the input pipe and the output pipe and sprayed obliquely downward, so that the high-strength defibrated wood pulp raw materials can be softened while being added, saving time.
