An industrial pulverizer with noise reduction and temperature reduction function

Abstract

The invention discloses an industrial grinder with noise reduction and temperature reduction functions. 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 formed above the grinding bin, guide plates are arranged in a feed channel between the feed port and the smashing bin, extrusion rolls are arranged below the guide plates, the stirring wheel and a rotating shaft are arranged in the grinding bin, teeth are arranged on the surfaces of the stirring wheel and the rotating shaft, an inverted trapezoidal discharge hopper is arranged at the bottom of the smashing bin, a filter net is arranged in the discharge hopper, a cooling liquid pipe cavity is further formed and surrounds the outer wall of the grinding bin, and a noise reduction layer is arranged on the outer side of the cooling liquid pipe cavity; a cooling water tank is arranged on the grinder body and communicated with the cooling liquid pipe cavity, and water is circularly supplied by the cooling water tank, so that the grinding bin is cooled. The industrial grinder can thoroughly grind a material, has a good grinding effect and is low in heat productivity and small in noise.

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
