Embodiment 1

[0018] The ultrafine pulverizer liquid nitrogen cooling device of this embodiment mainly includes a liquid nitrogen tank 1, a liquid nitrogen pump 7, a vacuum insulation pipeline 8, a water bath vaporizer 9, a stainless steel coolant tank 13, a coolant pump 19, and a coolant 21 , Electric control system 22.

[0019] When working, first check whether the liquid nitrogen tank level gauge 2 and the liquid nitrogen tank pressure gauge 5 are normal, and the manual valve 4 of the liquid nitrogen injection port and the manual valve 15 of the sewage discharge port should be in the closed state. First open the manual valve 6 of the liquid nitrogen tank, turn on the power and press the electric control button 22-1 to start the system, the liquid nitrogen pump 7 starts to run, and the liquid nitrogen flows from the liquid nitrogen tank 1 through the vacuum insulation pipeline 8 into the water bath vaporizer 9 In the water-bath evaporator 9, the nitrogen vaporizes and absorbs heat, change...

Abstract

The invention belongs to the technical field of cooling equipment structures, and relates to an ultrafine grinder liquid nitrogen cooling device comprising a liquid nitrogen tank carrying liquid nitrogen and a vaporizer communicated with the liquid nitrogen tank. The vaporizer is arranged in a cooling liquid tank and is provided with a nitrogen outlet communicated with outside of the cooling liquid tank, and the cooling liquid tank is filled with cooling liquid and is provided with a temperature sensor; the output end of the cooling liquid tank is communicated with a cooling liquid circulating outlet pipeline, part of the cooling liquid circulating pipeline wraps an ultrafine grinder cooling disc, and the output end of the cooling liquid circulating pipeline is communicated to the inside of the cooling liquid tank; a liquid nitrogen pump is mounted between the liquid nitrogen tank and the vaporizer; the cooling liquid circulating outlet pipeline is provided with a cooling liquid pump, and the liquid nitrogen pump, the cooling liquid pump and the temperature sensor are controlled by an electric control system. The ultrafine grinder liquid nitrogen cooling device is reasonable in structural design, high in safety and reliability, small in occupation, and capable of decreasing the temperature of the material smashed by an ultrafine grinder greatly.

Description

technical field [0001] The invention relates to a liquid nitrogen cooling device for an ultrafine pulverizer, and belongs to the technical field of cooling equipment structures. Background technique [0002] The ultrafine pulverizer is a device that uses air separation, heavy pressure grinding, and shearing to achieve ultrafine pulverization of dry materials. It has a wide range of applications and high fineness of the finished product, so it is widely used in food, chemical, pharmaceutical, feed, etc. multiple industries. Our common flour is generally about 100 mesh, and the superfine pulverizer can crush the raw materials to 1000 mesh or even higher. Due to the high fineness, the nutrients of food and medicine are easily absorbed by the human body. Therefore, there is a great demand for ultrafine pulverizers in the food and pharmaceutical industries. However, since the ultrafine pulverizer uses air separation, heavy pressure grinding, and shearing to achieve ultrafine p...
