Description
Technical field
The utility model relates to low-temperature quick-freezing technical field, is specifically related to a kind of wind defrosting heat sink of evaporimeter of instant freezer.
Background technology
At quick-frozen industry field, the application of instant freezer is more and more extensive, and make ice crystal tiny because of its snap frozen thus reach the feature of food fresh keeping, position is in social life more and more higher, becomes a kind of equipment that people are indispensable.In quick-frozen process, owing to occurring that make evaporimeter occur fin frost in heat transfer process, this will make the coefficient of heat transfer greatly reduce containing features such as moisture in the reason of heat exchange and air, defrosting be each enterprise necessary faced by problem.
Different according to region, atmospheric water content height is different, and defrosting time also has difference, be generally 8 hours to 12 hours.Conventional defrost is water defrosting, hot fluorine (ammonia) defrosting, electricity defrosting etc.; these Defrost methods all need to shut down defrosting, about 2 hours of defrosting time, and the working time of such every day just reduces about 4 hours; cause the waste of manual time, also greatly reduce the service efficiency of equipment.
Utility model content
It is that existing instant freezer evaporator defrost needs to shut down and causes the increase of cost of labor in defrost process, the technical problems such as the utilization rate reduction of equipment that the utility model will solve.Thus provide a kind of needs to shut down the wind defroster that can realize defrosting.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A kind of wind defroster, comprise pressurized tank, pressurized tank right-hand member is provided with air inlet pipe; Pressurized tank lower end is provided with blowoff valve; Electromagnetic impulse valve is vertically mounted on the upper end of pressurized tank and is connected with the output of controller; Electromagnetic impulse valve is connected with gas-distributing pipe by appendix; Gas-distributing pipe is provided with several nozzles.
Described controller is PLC.
Described appendix is T-shaped appendix.
Described appendix at least one.
Each appendix is connected in parallel at least two gas-distributing pipes, gas-distributing pipe can be simultaneously jet, improves the efficiency of defrosting.
In air accumulator upper end, safety valve is installed, improves safety coefficient.
In air accumulator lower end, support is installed, convenient placement.
Described appendix and gas-distributing pipe are steel tube, stabilized structure, and long service life.
In the utility model, gas-distributing pipe is provided with the side of nozzle towards evaporimeter, large quantity of air is stored in air accumulator, electromagnetic impulse valve separated in time under the control action of controller is opened once, compressed air in pressurized tank enters appendix through electromagnetic impulse valve, and then enter gas-distributing pipe, blow on the fin of evaporimeter by the equally distributed nozzle on gas-distributing pipe, the frost on evaporator fin is blown off.The utility model does not need to shut down the defrosting work that can realize evaporimeter, saves cost of labor, improves the utilization rate of defrosting efficiency and equipment.The utility model structure is simple, and cost of investment is low.

Wherein, T-shaped appendix and gas-distributing pipe 10 are steel tube.
Operation principle: the utility model gas-distributing pipe 10 is provided with the side of nozzle 2 towards evaporimeter.Electromagnetic impulse valve 4 is under the control action of controller 11, open once at interval of certain hour, compressed air in pressurized tank 5 enters T-shaped appendix by electromagnetic impulse valve 4, compressed air is dispensed to the gas-distributing pipe 10 be connected in parallel thereon by T-shaped appendix, compressed air blows on the fin of evaporimeter 1 by equally distributed nozzle 2 by gas-distributing pipe 10, is blown off by the frost on evaporimeter 1 fin.Entered in instant freezer by the frost blown off along with the fan airflow on evaporimeter, fall at ground or other positions.After frost on evaporimeter 1 fin is blown off, the coefficient of heat transfer is improved.
Embodiment 2: a kind of wind defroster, comprises pressurized tank, and pressurized tank right-hand member is provided with air inlet pipe.Pressurized tank lower end is provided with blowoff valve and support.In air accumulator upper end, safety valve is installed.
Electromagnetic impulse valve is vertically mounted on the upper end of pressurized tank and is connected with the output of controller.Described controller is PLC.Electromagnetic impulse valve is connected with gas-distributing pipe by appendix.Described appendix is T-shaped appendix, and gas-distributing pipe to be connected in parallel on T-shaped appendix and to be evenly provided with several nozzles on gas-distributing pipe.
Wherein, T-shaped appendix and gas-distributing pipe are steel tube.
