The low temperature grinder has the advantages of reasonable structure, high automation degree and strong practicality.
Description
Technical field
The present invention relates to a kind of pulverizer, relate in particular to a kind of Lowtemperaturepulverizer.
Background technology
Pulverizer is when comminuting matter, and the heat that produces in its particle crushing process makes the pulverizing chamber temperature rise, thereby the meltable soft junction piece of material destroys its active material, makes the energy consumption of material pulverizing high, yields poorly, causes material grinding efficient low.Existing pulverizer adopts and to reduce temperature to spraying into liquid nitrogen in feed cavity and the pulverizing chamber, but needs the workman hand-manipulated, and inefficiency is wasted time and energy, automaticity is low, therefore, should provide a new technical scheme to address the above problem.
Summary of the invention
The objective of the invention is: to above-mentioned deficiency, a kind of rational in infrastructure, time saving and energy saving, Lowtemperaturepulverizer that automaticity is high is provided.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of Lowtemperaturepulverizer comprises frame, feeder, pulverizing chamber, is provided with main shaft in the said pulverizing chamber; Stationary knife and moving knife are installed on the said main shaft; Said feeder comprises feed hopper and screw feeding device, and said screw feeding device is located in the feed cavity, is equipped with the liquid nitrogen shower nozzle on the chamber wall of the inwall of said pulverizing chamber and feed cavity; Said liquid nitrogen shower nozzle links to each other with the liquid nitrogen generation device through the liquid nitrogen control valve; Be provided with sensor in the said pulverizing chamber, said sensor is electrically connected with sensing assays device on being located at control circuit board, and said sensing assays device is electrically connected with the control processor; Said control processor is electrically connected with linked switch, and said linked switch is electrically connected with the liquid nitrogen control valve.
Further, the inwall of pulverizing chamber is provided with adiabator layer.
Lowtemperaturepulverizer of the present invention is provided with sensor in pulverizing chamber, the sensor of being located in the pulverizing chamber can be sensed the temperature value in the pulverizing chamber; And sending this value to the sensing assays device, the sensing assays device is electrically connected with the control processor, controls processor and is electrically connected with linked switch; Linked switch is electrically connected with the liquid nitrogen control valve, if the temperature in the pulverizing chamber surpasses normal temperature, linked switch will be opened automatically; Then open the liquid nitrogen control valve; Hydrojet nitrogen is lowered the temperature to pulverizing chamber in pulverizing chamber, has replaced traditional manual operation.
Advantage of the present invention is: rational in infrastructure, automaticity is high, practical.
