Description

A kind of freezer damping device

Technical field

This utility model is related to technical field of refrigeration equipment, more particularly, to a kind of freezer damping device.

Background technology

Continuous improvement with living standards of the people and the continuous extension of foreign trade, cold chain market development is swift and violent, people To the requirement also more and more higher depositing commercial quality in freezer, some commodity as fruit and vegerable have substantial amounts of moisture content in itself, This is to maintain the dynamic essential condition with freshness of its life words.Because water content is high, its saturated vapor pressure is higher than environment Saturated vapour pressure, during Long-term Storage in storehouse, because blower fan refrigeration can take away large quantity of moisture, not only makes its weight subtract Few, and product dehydration can be led to lose due value, in this case, generally require in freezer according to different commodity Requirement to storage humidity controls relative humidity between 85% one 95%, this be accomplished by cool house internal space is carried out plus Wet.

At present in actual production, frequently with the moisture to keep fruit as much as possible for the method for ground watering, but for a long time Will be frozen using this method ground, thus leading to occur during the action of personnel's vehicle skidding wrestling and causing security incident, this other places Face has water to have ice also easily to damage ground impact ground service life for a long time.

Place the mode that large quantities of buckets are humidified and take that Reservoir area is big in freezer, impact freezer logistics operation is convenient Property, meanwhile, the water in bucket, due to being that static state is easy to freeze, needs often to change, and wastes a large amount of manpower and materials.

Air-humidification method using ultrasonic humidifier needs perforate or reserved passageway on freezer wall, and the library is incubated not Profit.In addition, ultrasonic humidifier is expensive, at low ambient temperatures, equipment failure rate is high and needs special messenger's humidification management, takes Work, time-consuming, uneconomical.Additionally, the shortcoming of ultrasonic atomization humidification is to erupt to bring into while a large amount of dampness toward in storage environment Hot-air, hot-air is met low temperature and is easily caused water smoke and condenses, and water smoke condenses to what fruit and vegetable surfaces easily caused pathogen and grows breeding.

Using the method for moisturizing complex operation of preservative film single fruit or FCL packaging, human cost is high, preservative film ventilation performance Difference easily adversely affects to fruit and vegerable, and a large amount of plastic package material uses post processing to bother, not environmentally.

Therefore, the high humility keeping environment below 0 DEG C is difficult, because the steam of in the air can condense formation ice crystal And so that the moisture of in the air is reduced, so that air humidity is declined.Air humidity is to form humidity by moisture in air, and water by Liquid switchs to the energy that the necessary approach of hydrone is to increase hydrone, so most commonly seen method is exactly to heat.Low temperature ring When adopting equal-enthalpy humidifying method during border, hydrone is difficult to obtain heat energy from low temperature environment, can make the two of water because ambient temperature is low Secondary evaporation rate exhausts, and droplets form even more can be made especially below 0 DEG C during environment to become crystal ice granule so that humidification was lost efficacy. When being humidified using common isothermal humidification device, nozzle spray vapor enter low temperature environment after cannot with air carry out good Rapid distribution makes hydrone gather in a large number and produces the crystallization of white haze shape micro ice crystal and so that humidifying effect is had a greatly reduced quality.

Therefore, up to the present, preferable ancillary technique is not also had can to solve the above problems well, in consideration of it, this Utility model proposes a kind of freezer damping device to solve these problems.

Content of the invention

This utility model is in order to overcome drawbacks described above present in prior art, there is provided a kind of freezer damping device.

For solving the above problems, the utility model proposes a kind of freezer damping device, including return flume, storage tank, return Waterpipe, water pump, water pipe, described return flume is arranged at freezer bottom, and described storage tank is arranged on freezer top, described time Waterpipe is arranged between described return flume and described storage tank and is used for connecting described return flume and described storage tank, described water pump It is arranged on for being transported in described storage tank the water in described return flume by described water return pipeline in described return flume, institute State water pipe and connect described storage tank and described return flume.

In technique scheme, the initiating terminal of described water return pipeline is provided with backwater gate valve, described water pipe initial End is provided with flowing water gate valve.

In technique scheme, the vertical direction of described water pipe cuts 1/3rd of entirely described water pipe.

In technique scheme, by the ramp of 3%-5%, clockwise convolution is laid in the surrounding of freezer described water pipe On wallboard, terminal is connected to described return flume, so that the water energy in storage tank is automatically flowed back in return flume along water pipe.

In technique scheme, in described return flume, automatic water supplement is carried out using ball-cock assembly.

In technique scheme, in freezer, it is additionally provided with humidity sensor, for measuring the humidity in freezer.

In technique scheme, described water pump is provided with controller, for according to humidity setting situation and described humidity The actual humidity that sensor transmits is controlling the opening and closing of described water pump.

The utility model proposes freezer damping device operation principle as follows：

Transfer signals in controller after humidity sensor detects the real-time humidity in freezer, when real-time humidity is little When arranging humidity, controller controls water pump to open, and the water in return flume is extracted in storage tank by water pump by backwater channel, when When water in storage tank exceeds spillwag chute, water begins to flow to pipelined channel, and current press the direction circulation of flowing water water channel in storehouse, Transpiring moisture, increases humidity, in flowing water water channel, unevaporated water is eventually returned to return flume, realizes circulating, and increases humidity. When the real-time humidity that humidity sensor detects is not less than setting humidity, controller controls water pump to cut out.Adopt in return flume Carry out automatic water supplement with ball-cock assembly, upper in figure backwater gate valve and flowing water gate valve are used for adjusting streamflow, it is to avoid current are excessive, overflow Go out flowing water water channel.Whole water system is to circulate, and also will not freeze in the too low storehouse of temperature.

When controller quits work, can also manually control closing and the unlatching of water pump, realize to reservoir endogenous dampness The control of degree.

This utility model is had the advantages that and advantage compared with prior art：

The manner to increase humidity using the water circulation of open lead, it is to avoid the excessive storehouse face of the occupancy of traditional approach Long-pending and artificial, realize low cost humidification automatically.The system also can achieve automatization, detects storehouse humidity using humidity sensor, Water pump is realized automatically turning on according to humidity setting situation, realizes fully automated humidification.Can to humidity requirement which according to product By the humidity long-term control of storehouse between 85%-90%.
