Embodiment

[0041] Such as figure 1 As shown, a kind of water-injection pulping equipment based on physical state change pulping of the present invention mainly includes a supporting device, a driving rotating device, an auxiliary rotating device, a crushing device 9 and a stirring device 8, a driving rotating device and an auxiliary rotating device Installed on the supporting device sequentially from bottom to top, the crushing device 9 is installed above the stirring device 8, the crushing device 9 is installed above the auxiliary rotating device, and the stirring device 8 is installed above the driving rotating device.

[0042] In the present invention, the pulping process is realized through the two links of the crushing device 9 and the stirring device 8. Through this design, water-injection-free pulping is realized, that is, the crushing of the large fragments 13 is realized through the crushing device 9, and the result of the stirring device 8 is generated. The required water 26 is...

Abstract

The invention provides non-water injection type pulping equipment based on state change. The non-water injection type pulping equipment mainly comprises a support device, a driving rotary device, an auxiliary rotary device, a crushing device and a stirring device, and is characterized in that the pulp is firstly crushed and then stirred, and the water required by stirring is produced in the crushing process. The non-water injection type pulping equipment has the advantages that by utilizing the solid-solid collision of ice blocks and large crushing materials in the crushing device, the crushing of large crushing materials and generation of water are realized; by utilizing the liquid-solid stirring of water and small crushing materials in the stirring device, the decomposing of the small crushing materials is accelerated, and the uniform pulp is produced; by utilizing a rotary material cylinder in the driving rotary device, the crushing and stirring power is provided; by utilizing the support device, the action force of the material cylinder is dispersed, and the rolling drag is reduced.

Description

technical field [0001] The present invention relates to a non-water-injection pulping equipment based on physical state change pulping, and in particular to a crushing of large crushed materials and generation of water through solid-solid collision between ice cubes and large crushed materials in the crushing device. The liquid-solid agitation of water and small scraps in the mixing device accelerates the decomposition of small scraps and generates a uniform slurry. The rotating device is driven to rotate the barrel to provide crushing and stirring power, and the support device is used to disperse the force of the barrel and reduce its rolling. Resistance belongs to the technical research and development field of pulping equipment. Background technique [0002] As one of the most commonly used pulping equipment in the pulp and paper industry, the hydraulic pulper mainly crushes pulp boards, waste books, waste cartons, etc. However, due to the singleness of the working mode ...
