An industrial pulverizer suitable for processing chemical, pharmaceutical and food raw materials

Abstract

The invention discloses an industrial grinder suitable for chemical engineering, pharmacy and food material processing. The industrial grinder comprises a grinder body and a storage bin, wherein the grinder body comprises a feed port, a variable frequency motor, a grinding bin, a stirring wheel and a discharge port; the feed port is arranged above the grinding bin, and a flow guiding plate is arranged in a feed channel between the feed port and the grinding bin, an extrusion roller is arranged below the flow guiding plate, the stirring wheel and a rotating shaft are arranged in the grinding bin, and the surfaces of the stirring wheel and the rotating shaft are respectively provided with teeth; the variable frequency motor is arranged on the grinding body, and the variable frequency motor is capable of respectively driving the stirring wheel, the rotating shaft and the extrusion roller to rotate through a connecting piece and / or a transmission tape; the bottom of the grinding bin is provided with an inverted trapezoidal discharge funnel, a filter net is arranged in the discharge funnel, a material conveying cavity is arranged below the grinder body, and the discharge port is formed at one side of the material conveying cavity. The material can be completely ground, the grinding effect is good, and the grinding efficiency is high.

Description

technical field [0001] The invention relates to a pulverizing device, in particular to an industrial pulverizer, which is suitable for processing and pulverizing chemical, pharmaceutical and food raw materials. Background technique [0002] At present, with the rapid development of the machinery industry, a large number of pulverizers are produced and used. In industrial production, putting solid block materials into the pulverizer for crushing and stirring evenly is the most commonly used production process in the pharmaceutical, chemical and food industries. Now Most of the pulverization techniques use hammer mills to beat solid block materials to make them pulverize. Hammer mills generally use a rotating shaft to drive a disc to rotate. A crushing hammer is set on the disc. During the rotation of the disc, the crushing hammer rotates at high speed and hammers, impacts, shears and grinds the material to make the material crushed.

Problems solved by technology

A crushing hammer is set on the disc. During the rotation of the disc, the crushing hammer rotates at high speed and hammers, impacts, shears and grinds the material to make the material crushed. Chinese patent document CN201120206993.X discloses a hammer mill , including the upper casing, the lower casing, the pulley, the rod and the hammer set on the rod, this hammer mill is driven by the pulley to rotate the rod, so that the hammer set on the rod rotates to crush the material , during the crushing process of this kind of hammer mill, because of the large gap between the hammer heads, some chemical raw materials are not completely crushed, and the crushing effect can only be found after the crushing is completed. Some Materials that have not been crushed can only be crushed for the second time, which affects the work efficiency, and because the hammer head rotates at high speed when the crusher is working and needs to beat the materials, it will generate a lot of heat. If the heat cannot be dissipated in time, it will cause High temperature affects the main body of the pulverizer, reducing its service life, thereby increasing the cost of the enterprise. At the same time, high temperature may also affect the properties of some of the crushed materials
