Description
Technical field
This utility model relates to a kind of cooling recirculation system, especially relates to a kind of sterilizing cabinet and cools off automatic controlled circulation system.
Background technology
Sterilizing cabinet is to utilize the means such as cabinet inner high voltage saturated vapor, superheated water spray or heated dry air to make protein in the microbial cells, nucleic acid etc. degeneration occur and killing microorganisms equipment.Take common water-bath sterilization cabinet as example, comprise the parts such as cavity, water-locator, plate type heat exchanger, water circulating pump.Its operation principle is that medicine subject to sterilization is put into sterilizing cabinet, injects purified water in cabinet, when purified water arrives certain altitude, close the purified water valve, start water circulating pump, open simultaneously large and small steam valve, by the purified water of plate type heat exchanger heating cabinet internal recycle.After the temperature of recirculated water reaches the technique initialization temperature, open little steam valve by the interval and control and keep sterilising temp in the cabinet.After finishing sterilization phase, closing all steam valves, give pressure release in the cabinet, is zero until relatively press in the cabinet, and water discharging to be recycled is complete, opens the cabinet door after the medicine temperature is lower than below 30 ℃.
Sterilizing cabinet need to be taken away heat in the cabinet with external medium when cooling, carry out heat exchange by plate type heat exchanger and low-temperature cooling water, and the cooling water that heats up by heat exchange is sent in the cooling tower, by cooling tower the waste heat discharge in the cooling water is entered in the air.Because sterilizing cabinet is intermittent duty, whole day accumulated running time only had about 13 hours, and effective run time is not long, but water circulating pump whole day 24 hours all in running, the water pump operation time is long, mechanical wear is large, the electricity consumption waste seriously; Existing blower fan of cooling tower opens and closes and adopts manually control, exist running uncontrollable, operate nonstandard phenomenon; And, do not adopt detection technique in the existing system, can't detect cyclic hydrostatic pressure and leaving water temperature, because the situation that recirculated water hydraulic pressure is inadequate, the too high sterilizing cabinet cooling-down effect that causes of recirculated water leaving water temperature is poor, temperature fall time is long often occurs.
Summary of the invention
This utility model mainly is that the sterilizing cabinet cooling system that solves prior art exists that automaticity is not high, water pump operation overlong time, waste are serious, without problems such as monitoring means, cooling-down effect are poor.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of sterilizing cabinet cools off automatic controlled circulation system, comprises cooling tower, switch board, water circulating pump, sterilizing cabinet; Described cooling tower top is provided with blower fan, and the blower fan below is provided with water inlet pipe, and the water inlet pipe below is provided with filler, and the cooling tower bottom is provided with outlet pipe, is provided with temperature sensor on described cooling tower water inlet pipe, the outlet pipe; Described sterilizing cabinet comprises plate type heat exchanger, and plate type heat exchanger one side is provided with cooling water intake, cooling water outlet, and opposite side is provided with recirculated water outlet, recirculated water water inlet; Water circulating pump one end is connected with the cooling tower outlet pipe by pipeline, the water circulating pump other end links to each other with the cooling water intake of plate type heat exchanger by pipeline, the cooling water outlet of plate type heat exchanger is connected with the water inlet pipe of cooling tower by pipeline, and described plate type heat exchanger cooling water intake is provided with pressure transducer.
As preferably, described cooling tower bottom also is provided with filling pipe, is provided with liquid level controller at filling pipe.
As preferably, be provided with converter, PLC in the described switch board, the trigger switch of described blower fan, liquid level controller, temperature sensor, pressure transducer, sterilizing cabinet all is electrically connected with PLC, and PLC is electrically connected with converter, and converter is electrically connected with water circulating pump.
It is high that this utility model is controlled sterilization cycle system automation degree automatically, can monitor water temperature, hydraulic pressure, blower fan, water pump in real time, can realize easily Long-distance Control, improve in the past manually-operated blower fan, the shortcoming that leaving water temperature is unstable, cooling effect is poor.Water pump just moves when sterilizing cabinet is worked; Blower fan just can be opened and carry out forced cooling when water pump operation and leaving water temperature surpass setting value; When cyclic hydrostatic pressure is inadequate, the controlled controlling the water circulation pump of PLC so just can reduce machine loss greatly to the cooling water supercharging, improves the phenomenon of the cooling prolongation that causes not because of cooling water pressure, save the operation expense of cooling recirculation system, have good promotional value.
