Fully automatic hydraulic pulping machine

Abstract

The invention discloses a fully automatic hydraulic pulping machine. The fully automatic hydraulic pulping machine comprises a feeding component, a machine base, a grinding disc component and a drive component, wherein the grinding disc component and the drive component are fixed to the machine base; the drive component comprises a main shaft connected with a drive mechanism; a space adjusting device is arranged on the main shaft; the space adjusting device comprises a worm wheel, a worm, a space adjusting sleeve and a mobile sleeve, wherein the worm is connected with the drive component; themobile sleeve is connected with a hydraulic drive cylinder; the space adjusting sleeve and the mobile sleeve are connected with the outer side wall of the main shaft; the worm wheel matched with the worm for driving is sleeved outside of the space adjusting sleeve; and the worm wheel and the space adjusting sleeve are in threaded fit. The fully automatic hydraulic pulping machine has the advantages of simple and compact structure, low cost, convenience for operation, stable and reliable work, and capacity of reducing energy consumption, reducing noise pollution, stabilizing finished pulp quality and the like.

Description

technical field [0001] The invention mainly relates to the field of pulp refining equipment, in particular to a fully automatic hydraulic pulp refiner suitable for papermaking, chemical industry and other fields. Background technique [0002] In the prior art, the high-consistency refiner is an important equipment in the pulping process that uses short fibers as papermaking raw materials. Most of this equipment is equipped with hydraulic automatic control devices, usually using ordinary hydraulic automatic control and constant power hydraulic pressure. There are two structural forms of self-control, and these two structural forms have a common disadvantage, that is, when the inlet of the mill has little slurry or no slurry, there will be severe friction between the tooth surfaces of the two grinding discs, the noise is loud, and the tooth surfaces are generated due to friction. High temperature and "annealing", thereby greatly reducing the hardness of the tooth surface and s...

Problems solved by technology

But sometimes there is an abnormal working state, that is, the flow rate of the pulp entering the refiner suddenly decreases, and even the pulp breaks. After this situation occurs, in addition to possible damage to the equipment, it will also cause strong cutting of the fiber when there is less pulp effect, thereby affecting the tensile strength of the finished paper, increasing the loss of fibers and wasting power consumption

However, the usual automatic control equipment of hydraulic equipment cannot prevent the damage caused by the above "empty grinding" phenomenon, which directly causes excessive shearing of fibers, and a large number of long fibers become short fibers, resulting in a large loss of fibers; Under the action of hydraulic pressure, the two grinding discs are tightly pressed together, causing severe air friction between the tooth surfaces of the two grinding discs, the friction noise between the metals is deafening, and the temperature of the two grinding discs rises sharply, greatly reducing the service life of the grinding discs , the heat generated by friction radiates outward to the outside of the equipment, which increases the temperature of the working environment, wastes a lot of energy, and increases production costs and sewage treatment costs; the reason for this is that the automatic control device for constant power refining cannot control Knife retraction action during empty grinding (no pulp or less pulp)
