The invention relates to the technical field of cleaning devices, and particularly discloses a cleaning device and method for material accumulation in a disc-type crushing cavity. A pointer scraper rod is arranged at the bottom of the disc-type crushing cavity and comprises a central shaft, a first scraper rod, a second scraper rod, and a third scraper rod, the first scraper rod, the second scraper rod, and the third scraper rod are all connected to the central shaft, the central shaft is inserted in the lower disc of the disc-type crushing cavity, the first scraper rod is attached to the lower disc lining of the disc-type crushing cavity, the second scraper rod is attached to the upper disc lining of the disc-type crushing cavity, and the third scraper rod is attached to the inner wall ofthe upper discharging opening in the disc-type crushing cavity; and a motor is arranged below the disc-type crushing cavity, and the pointer scraper rod is connected to the motor through a coupling.According to the cleaning device, the problem of the accumulation of materials in the crushing cavity can be solved, the problem of powder accumulation in the crushing cavity in the continuous production of viscous materials is solved, a lot of manpower and material resources are saved, the design of the pointer scraper rod does not affect the particle size after crushing, and the aseptic production requirements are met.
Description
technical field [0001] The invention relates to the technical field of cleaning devices, in particular to a cleaning device and a cleaning method for material accumulation in a disc-type crushing cavity. Background technique [0002] There are mainly several types of jet mills used in my country's industry: disc jet mill, fluidized bed jet jet mill, circulating tube jet mill, counter jet jet mill, target jet mill, spiral jet mill Jet mill. [0003] The disc airflow mill is a mechanical device that relies on high-pressure airflow to push the material to make a circular motion inside the crushing chamber, and then crush it after repeated collisions and frictions. The recovery rate of the crushed sample is as high as 99%, and the particle size of the finished product can reach 2 microns, suitable for high value-added sample crushing such as drug micronization. [0004] The disc-type jet mills on the market now have high requirements for the viscosity and hardness of the materi...
