Background technique

In the papermaking process, pulp boards, waste books, waste cartons, etc. need to be shredded to make the pulp required in the paper industry, and the hydropulper is the most common equipment in this process. The hydropulper passes through The movement of the rotor crushes the waste in the water to make a uniform suspension. However, due to the singleness of the working mode and structure of the current pulper, the following problems are caused: First, the efficiency is low. The pulping process of the existing pulper is mainly realized by the mechanical collision between the feed liquid and the rotor and the barrel wall. It comes from the agitation of the rotor to the liquid material, and in the process of pulping, a part of the energy will be consumed in the reactive power loss of the machine, resulting in low efficiency of mechanical pulping; secondly, the energy consumption is large, and the pulper rotor is in the working process In the process, it is not only necessary to drive the fluid to rotate, but also to overcome the resistance of the fluid, which consumes a lot of mechanical energy to a certain extent.

Therefore, in view of the common problems of low efficiency and high energy consumption in the use of existing pulpers, it is necessary to comprehensively consider the working mode and structure of the pulper, and design a system with high pulping efficiency and low energy consumption. slurry equipment.

Contents of the invention

The utility model aims at the problems of low efficiency and high energy consumption in the existing pulping equipment, and provides an air flow vortex kinetic energy pulper which can effectively solve the above problems.

An airflow vortex kinetic energy pulper of the utility model adopts the following technical scheme:

An air flow vortex kinetic energy pulper, mainly comprising an air compressor, a gas delivery main pipe, a cylinder body, and a gas delivery branch pipe, the outlet of the air compressor is connected to the gas delivery main pipe; one end of the gas delivery main pipe is connected to the other end of the air compressor Connected to the gas delivery branch; the gas delivery branch is two, the gas delivery branch is drawn from the gas delivery main pipe, extends from the outside to the inside of the cylinder on both sides of the same radial direction, and extends 1/4 clockwise along the inner bottom of the cylinder Circumferentially, the outlets of the gas delivery sub-pipes are symmetrically arranged on both sides of the same radial direction; the lower end of the cylinder is equipped with pillars, and the number of pillars is four.

The diameter of the gas delivery main pipe is D, the diameter of the gas delivery sub-pipe is D/2, and the bend of the gas delivery main pipe and the gas delivery sub-pipe is provided with a fillet transition, and the fillet R is D/10.

The height of the cylinder is H, and the height of the interface between the gas delivery branch pipe and the gas delivery main pipe is H/3 from the bottom of the cylinder.

In the utility model, two gas delivery pipes are designed, which extend clockwise for 1/4 of the circumference at the inner bottom of the cylinder, and the outlets of the gas delivery pipes are symmetrically arranged on both sides of the same radial direction. Through this design, the generation of vortex water flow can be realized. That is to say, the compressed air ejected from the gas delivery branch still moves along the circumference under the action of inertial force, which can promote the circular motion of the static material-liquid mixture, and then form a vortex. Cartons and other waste materials are crushed; while the outlets of the gas delivery pipes are symmetrically arranged on both sides, this design can provide sufficient gas source for the circular motion of the liquid mixture to ensure the kinetic energy required for vortex pulping; in addition, two The gas conveying branch pipe can realize partial blocking of eddy current and prevent the vortex from producing "swirl cake" phenomenon in the smooth cylinder.

In the utility model, the diameter of the main gas delivery pipe is designed as D, and the diameter of the gas delivery sub-pipe is designed as D/2. Through this design, the gas flow of the two gas delivery sub-pipes can be the same to ensure the stable operation of the vortex; the gas delivery main pipe There is a round corner transition at the bend of the gas delivery pipe, which can reduce the loss of gas kinetic energy caused by the sudden change of the local flow channel of the gas delivery pipeline and reduce the reactive power consumption.

In the utility model, the interface between the gas delivery sub-pipe and the gas delivery main pipe is designed to be at a height of H/3 from the bottom of the cylinder body. Through this design, the compressed air ejected at a high speed can have a buffer flow distance in the gas delivery main pipe, and can be used in a relatively short time. The shunt can be realized under small pressure loss, and it also has the effect of beautiful structure. That is, when there is a small pressure loss, the flow is diverted through the pipeline, and the airflow is accelerated with the help of a narrow pipeline, so as to increase the kinetic energy and minimize the loss of the total gas energy; The height of the bottom is low, and there may be local impact of high-pressure gas on the pipe wall, resulting in premature damage to the pipe wall at the interface; if the height of the interface between the gas delivery branch pipe and the gas delivery main pipe is relatively high from the bottom of the cylinder, gas pressure loss may occur Too large will cause a large loss of air flow energy; in addition, the height of the bottom of the cylinder is H/3, which has the advantages of balanced structural proportion and beautiful appearance in terms of shape and appearance design.

The beneficial effects of the utility model are: the generation of vortex is realized by two gas delivery sub-pipes extending clockwise for 1/4 of the circumference and arranged symmetrically in the same radial direction, and the diameter of the gas delivery sub-pipes is designed to be 1/2 of the main gas delivery pipe. The stable operation of the vortex; the reduction of energy consumption through the transition of the rounded corners at the bend; the design of the height of the gas delivery branch pipe and the gas delivery main pipe interface from the bottom of the cylinder is H/3 to minimize the total gas energy loss and shape Beautiful design.

The outer side of the body 4 extends to the inner side, and extends 1/4 of the circle clockwise along the inner bottom of the cylinder body 4, and the outlets of the gas delivery branch pipes 5 are symmetrically arranged on both sides of the same radial direction. When working, this design can realize the generation of vortex water flow, that is, the compressed air ejected from the gas delivery branch pipe 5 still moves circumferentially along the circumference under the action of inertial force, which can promote the static material-liquid mixture to generate Circular motion, and then form a vortex, the material-liquid mixture in the pulping area 6, under the action of the vortex, promotes the waste materials such as waste cartons to be broken down; and the outlet of the gas delivery branch pipe 5 is symmetrically arranged on both sides. This design can be used for the circumference of the liquid mixture. The movement provides sufficient air source to ensure the kinetic energy required for vortex pulping; in addition, the two gas delivery pipes 5 in the cylinder 4 can realize partial blocking of the vortex and prevent the vortex from producing "rotary cake" in the smooth cylinder 4 Phenomenon. A pillar 3 is installed at the lower end of the cylindrical body 4, and the number of the pillar 3 is four.

As shown in Figure 3, the diameter of the main gas delivery pipe is D, and the diameter of the gas delivery sub-pipe is D/2. This design can achieve the same flow rate of the gas 7 of the two gas delivery sub-pipes 5 and ensure the stable operation of the vortex. The bends of the main gas delivery pipe 2 and the gas delivery sub-pipe 5 are provided with a fillet transition, and the fillet R is D/10, which can reduce the gas kinetic energy loss caused by the sudden change of the local flow channel of the gas delivery pipeline and reduce the reactive power consumption.

The height of the cylinder body 4 is H, and the height of the interface between the gas delivery branch pipe 5 and the gas delivery main pipe 2 is H/3 from the bottom of the cylinder body 4 . This design can not only realize that the compressed air jetted out at a high speed has a buffer flow distance in the gas conveying main pipe 2, can realize shunting under a small pressure loss, but also has the effect of beautiful structure. During work, if the height of the interface between the gas delivery sub-pipe 5 and the gas delivery main pipe 2 is relatively low from the bottom of the cylinder body 4, the local impact of the high-pressure gas 7 on the tube wall may occur, causing premature damage to the tube wall at the interface; such as gas delivery The connection between the sub-pipe 5 and the gas delivery main pipe 2 is relatively high from the bottom of the cylinder body 4, and the pressure loss of the gas 7 may be too large, resulting in a large loss of kinetic energy of the gas. In addition, the height from the bottom of the cylinder body 4 is designed to be H/3, which has the advantages of balanced structural proportion and beautiful appearance in terms of shape and appearance design.
