Introduction
Toothed claw crusher (stainless steel pulverizer) is widely used in feed, pharmaceutical, chemical, food, non-metallic ore and other industries, suitable for crushing dry brittle materials. The structure of this machine is simple and solid, the operation is stable, the crushing materials are fast and uniform, and the effect is good. This machine is made of high-quality stainless steel material, and the inside of the casing is processed by precision machining to achieve the effect of smooth surface and easy cleaning, which changes the phenomenon of rough inner wall of ordinary pulverizer, easy to accumulate powder and difficult to clean, so that food, medicine, chemical and other production can better meet national standards and meet the health requirements of GMP.
Structure and working principle
This machine is composed of feeding hopper, body, rotor disk, sieve plate, stator disk, discharge port,pulse dust collector and other parts. The spindle of this machine is equipped with a rotor disk, the rotor disk is equipped with tooth claws and flat steel teeth, the crushing chamber cover and the end face of the rear cavity are equipped with fixed tooth claws, and the tooth claws and flat steel teeth on the rotor disc are staggered with fixed tooth claws. When the spindle runs at high speed, the rotor disc also runs at the same time, and the material is thrown into the gap between the tooth jaws, and crushed under the comprehensive action of mutual impact, shearing, friction and so on between the material and the tooth jaw or the material with each other. The crushed material is driven by the air flow, along the outer edge of the rotor, continuously withstand the blow of the tooth claw and sieve blade, collide, rub and be quickly crushed.
Pulse dust collector refers to the method of blowing compressed air to remove the dust attached to the filter medium (cloth bag or filter cartridge); According to the size of the dust collector may have several groups of pulse valves, controlled by the pulse controller or PLC, each time open a set of pulse valves to remove the dust of the part of the bag or filter cartridge controlled by it, while other bags or filter cartridging work normally, after a period of time, the next set of pulse valves open, clean the next part of the dust collector by the ash bucket, the upper box, the middle box, the lower box and other parts. The upper, middle and lower boxes are divided into chambers. When working, the dust-containing gas enters the ash hopper from the inlet air duct, the coarse dust particles directly fall into the bottom of the ash hopper, the fine dust particles enter the middle and lower box with the airflow turning point, the dust accumulation is attached to the outer surface of the filter bag, the filtered gas enters the upper box to the clean gas collection tube - exhaust air duct, and is discharged to the atmosphere by the exhaust fan. The cleaning process is to cut off the clean air outlet duct of the chamber first, so that the cloth bag of the chamber is in a state of no air flow through (separate chamber stop air cleaning). Then the pulse valve is opened and the compressed air is used to pulse the ash cleaning. The closing time of the cutting valve is enough to ensure that the dust removed from the filter bag after the injection is settled to the ash hopper, avoiding the phenomenon that the dust is separated from the filter bag surface and attached to the adjacent filter bag surface with the air flow, so that the filter bag is cleaned thoroughly, and the exhaust valve, pulse valve and ash unloading valve are fully controlled by the programmable controller. The dust-containing gas enters through the air inlet, and when it passes through the ash hopper, part of the large particle dust in the gas is separated by the inertial force and gravity, and falls directly into the bottom of the ash hopper. The dust-containing gas enters the filter bag filter area of the middle box after passing through the ash hopper. The gas passes through the filter bag, and the dust is blocked on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag mouth and then is discharged by the outlet.
