Description
Technical Field
[0001] The utility model relates to the technical field of paper production, in particular to a papermaking pulp crushing and mixing device. Background Art
[0002] Papermaking is one of the four great inventions of China. In the Western Han Dynasty, people had already understood the basic method of papermaking. In the Eastern Han Dynasty, the eunuch Cai Lun summarized the experience of his predecessors and improved the papermaking process. He used plant fibers such as tree bark, hemp heads, rags, and old fishing nets as raw materials to make paper. The quality of paper was greatly improved. This kind of paper raw material is easy to find, cheap, and easy to promote. Since then, the use of paper has become increasingly common. Paper has gradually replaced bamboo slips and silk and become a widely used writing material, which has also facilitated the spread of classics.
[0003] The existing patent discloses CN202222436366.6, a raw material crusher for pulp production, comprising: a crushing machine body; and a fixed block, which is fixedly connected to the crushing machine body; a rotating disc, which is arranged inside the crushing machine body; a limiting ring block, which is fixedly connected to the rotating disc and extends to the inside of the fixed block; a driven shaft, which is movably connected to the rotating disc. The raw material crusher for pulp production mixes water and shredded paper and passes them into the inside of the crushing machine body. At this time, the water and shredded paper are mixed with each other to form a rough pulp. By energizing the power motor to work, the power motor drives the driven shaft to move through the planetary gear mechanism, and drives the connecting sleeve to rotate through the transmission mechanism. The rotation direction of the connecting sleeve is opposite to that of the driven shaft. At this time, the crushing cutter body rotates while also performing a circular motion, and the upper and lower crushing cutter bodies rotate in opposite directions, so that the crushing effect is better, but the following problems still exist;
[0004] The pulverizing method adopted in this patent document, due to the presence of a certain space between the lower end of the pulverizing blade body and the lower wall of the pulverizer body, is prone to cause certain pulverizing dead angles when the paper is pulverized, and cannot effectively ensure the pulverizing and mixing effects of the pulp. In addition, during the processing, it is easy for un-pulverized pulp to hide in the discharge pipe, which greatly reduces the pulverizing effect of the pulp. In view of this, there may already be technical means to solve the above problems in the prior art, but this case intends to provide an alternative or replacement technical solution.
