Energy-saving controllable low-temperature freezing point pulverizing device

Abstract

The invention discloses an energy-saving controllable low-temperature freezing point pulverizing device. The energy-saving controllable low-temperature freezing point pulverizing device comprises a pulverizing motor, a pulverizing mechanism, a heat pump, a material bin, a dry ice bin, a mixing bin, a classifying bin, a pulverizing bin and a classifying turbine; the pulverizing motor is installed at the lower end of the pulverizing bin through a base; the pulverizing mechanism is installed in the pulverizing bin through the pulverizing motor; the lower end of the pulverizing bin is provided with a cold air inlet communicating with an inner cavity of the pulverizing bin; the cold air inlet is located in the lower portion of the pulverizing mechanism; the cold air inlet is connected with an cold air outlet of the heat pump through a cold air pipe; the material bin and the dry ice bin are connected with the feeding end of the mixing bin; the discharging end of the mixing bin is connected with the pulverizing bin through a screw feeder; the screw feeder communicates with the inner cavity of the pulverizing bin; the classifying bin is installed at the upper end of the pulverizing bin through a convex cover; the classifying bin is provided with a classifying motor; and the classifying turbine is connected with the classifying motor. Materials can be prevented from being pulverized ata high temperature, the quality of the pulverized materials is ensured, and cooling capacity can be fully utilized.

Description

technical field [0001] The invention relates to crushing equipment technology, in particular to an energy-saving and controllable low-temperature freezing point crushing device. Background technique [0002] The crushing device is widely used in the pharmaceutical industry, especially in the crushing and processing industry of Chinese herbal medicines with high temperature requirements. At present, the commonly used crushing devices include hammer type, ball mill type, air flow type and other crushing devices. Although there are many ultra-fine pulverizing devices at present, many of the ultra-fine pulverizing devices currently in use do not have a cooling or freezing system. During the continuous pulverizing process, a large amount of heat will be generated due to mutual friction and collision with the pulverizing hammer. If the heat is not taken away in time, various problems such as coking, clogging, volatilization and loss of effective components will occur for those su...
