Problems solved by technology

In short, papermaking wastewater makes river water turbid and foul-smelling, aquatic plants are not growing, fish and shrimp are gone, mosquitoes and flies are overgrown, and maggots are everywhere, which seriously threatens the health of residents along the coast, causing diseases such as dysentery, enteritis, and scabies to prevail. At the same time, it is not conducive to farmland. Irrigation and drinking water for humans and animals

Embodiment Construction

[0014] Specific embodiments of the present invention are described with reference to the accompanying drawings.

[0015] As shown in the drawings: the pulping device includes a main body 5 and a motor. The main body 5 is provided with a feed port 6, and the cylinder is arranged in the main body 5. In the cylinder, a screw shaft 7 is arranged. One end of 7 is connected to the motor, and the shaft of the screw shaft 7 is a tapered structure whose diameter gradually increases from the feed port 6 to the discharge port 8. This structure can make the gap between the screw shaft and the inner wall of the cylinder open from the feed port 6 From the position to the discharge port 8, it decreases successively. There is a spiral groove on the inner wall of the cylinder, and the depth of the spiral groove gradually decreases from the inlet 6 to the outlet 8. This structure can make the gap between the helical teeth on the screw shaft 7 and the spiral groove on the inner wall of the cylin...

Abstract

The invention relates to a paper making pulp manufacture method which includes that the fiber material after dipped is arranged into a cylinder; the material rotates at a high speed between a rotary shaft and the inner wall of the cylinder under the action of the rotary shaft; the material generates high temperature high pressure phase transition under kneading and extruding; pressure is released suddenly at the discharge opening of the cylinder to lead the cylinder to blow up, thus finishing fiber dissociation and fibrillating; the pulp is extruded out from the discharge opening. The paper making pulp manufacture device includes a main motor body and a motor. A feed opening is arranged on the main motor body; the cylinder is arranged on the main motor body; a spiral shaft is arranged in the cylinder; one end of the spiral shaft is connected with the motor; the shaft rod of the spiral shaft is a conical structure with a diameter gradually increasing from the feed opening to the discharge opening; a spiral slot is arranged on the inner wall of the cylinder; the depth of the spiral slot is decreased gradually from the feed opening to the discharge opening. The invention finishes the fiber dissociation and fibrillating during the pulp manufacture process and has the advantages of low energy consumption and no pollution.

Description

technical field [0001] The invention belongs to the field of pulp making technology and equipment, and mainly relates to a low energy consumption and pollution-free pulp making method and a device thereof. Background technique [0002] In the traditional pulping process, in order to separate the fibers, two types of pulping are commonly used: alkaline pulping and sulfite pulping, and a large amount of chemical reagents are used in this process. Chemical pulping in industrial production includes three basic processes of material preparation, cooking and purification. The digester is the basic equipment in the cooking process of chemical pulping. The main part of various digesters is a metal pressure-resistant container with a large volume. The equipment is complex, the investment is high, and the operation and management level is also high. The coarse stock made by cooking can only be used as pulp after proper purification. Pulp purification generally includes washing, scre...
