Abstract

The utility model relates to an enforced mixing circulation liquid supply device which is composed of an evaporator, a low-pressure circulation barrel, an electromagnetic valve, a throttling valve, a stop valve, a refrigerating compressor, a high-pressure liquid storage barrel, a liquid level controller, a high and low-pressure liquid splicer, a one-way valve, an oil separator, a condenser, a sleeve pipe type liquid separating and collecting dry pipe, a dry filter, an oil collector, etc. The utility model cancels the original liquid pump having liquid supply power and uses a high-pressure liquid supply flow pipe led by the high-pressure liquid storage barrel, a low-pressure liquid supply flow pipe and the high-pressure liquid supply flow pipe are arranged on one same guiding splicer, and therefore, the utility model achieves the goal that the enforced mixing circulation liquid supply device supplies liquid to the evaporator. The utility model has simple and practical structure, low manufacturing cost, high refrigerating efficiency and low energy consumption.

Description

Forced Mixing circulation liquid feed device

The utility model relates to a kind of liquid feed device, particularly a kind of Forced Mixing circulation liquid feed device.

Refrigeration is to circulate in a closed-system by cold-producing medium, constantly changes its state, thereby acquisition low temperature.The feed liquid way of vapour compression refrigeration system mainly contains direct throttling feed flow, three kinds of gravity force liquid-supply and liquid pump to supply refrigerant at present.They all respectively have pluses and minuses, and are simple in structure as direct throttling feed flow, do not consume other power.Shortcoming is to regulate difficulty, and the liquid hammer accident takes place easily, for asking the return tube that will extend safely.But return tube can be overheated, and refrigerating efficiency is lower, uses in big-and-middle-sized refrigeration system, particularly to the evaporimeter feed flow of many groups parallel connection, is difficult to distribute equably by designing requirement.Gravity force liquid-supply is replaced by liquid pump to supply refrigerant gradually because of more shortcoming is arranged; But liquid pump to supply refrigerant should consumption of power increases the maintenance work of pump again, and flow because of having liquid formation two-phase in the return tube, the flow resistance of this liquid is bigger than monophasic fluid, therefore to strengthen caliber and correspondingly strengthen equipment such as valve member, increase the charging amount of cold-producing medium, investment cost is higher, and energy consumption is also bigger.Therefore also useful abroad heat pump feed flow replaces liquid pump to supply refrigerant, but because the heat pump feed flow needs quality good, automatic control valve member fault in case take place in the automatic control valve member of reliable in action, will cause whole refrigeration system all can't normally move and quit work, also be difficult to be widely used for the moment.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of and introduce highly pressurised liquid by the high pressure liquid receiver and make feed flow power, thereby can be to the Forced Mixing circulation liquid feed device of evaporimeter feed flow.

The purpose of this utility model can reach by following measure: the utility model comprises evaporimeter, the low pressure recycle bucket, magnetic valve, choke valve, stop valve, refrigeration compressor, the high pressure liquid receiver, fluid level controller, oil eliminator, condenser, oil catcher, it is characterized in that: the high pressure liquid receiver is connected with high-low pressure liquid phallus for fluid flow tube by high pressure, the high pressure feed pipe is provided with shutoff valve, the low pressure recycle bucket is connected with high-low pressure liquid phallus by low press juice stream pipe, the low pressure drain pipe is provided with check valve, low press juice stream pipe is connected with high-low pressure liquid phallus, and high-low pressure liquid phallus supplies fluid flow tube and low press juice to flow pipe with same guidance mode and connect high pressure.

The purpose of this utility model can also reach by following measure: also can be provided with magnetic valve, device for drying and filtering at high pressure on the fluid flow tube, also can be provided with magnetic valve on low press juice stream pipe.

Fig. 1 is a structural principle schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, the utility model is made of evaporimeter 1, low pressure recycle bucket 2, magnetic valve 3, choke valve 4, stop valve 5, refrigeration compressor 6, high pressure liquid receiver 7, fluid level controller 8, high-low pressure liquid phallus 9, check valve 10, oil eliminator 11, condenser 12, bushing type separatory liquid collecting main 13, device for drying and filtering 14, oil catcher 15 etc.

The utility model has saved the original liquid pump that plays feed flow power, changes the high pressure of being introduced by the high pressure liquid receiver and is replaced for fluid flow tube; Low pressure supplies fluid flow tube and high pressure feed flow flow duct facility on the phallus 9 of same guiding.Concrete operation principle is:

Refrigeration compressor 6 sucks refrigerant vapour, be compressed into high-pressure and high-temperature steam and enter oil eliminator 11, the bigger lubricated oil droplet of density is separated, and the lighter high-pressure and high-temperature steam of density is removed condenser 12 through oil eliminator, in condensation to the cooling water heat release, be condensed into highly pressurised liquid and flow into high pressure liquid receiver 7, be assigned as two the tunnel: the one tunnel and enter low pressure recycle bucket 2 after choke valve 4 throttlings, the drain pipe of low pressure recycle bucket 2 is connected with high-low pressure liquid phallus 9; The high pressure of mechanical pump effect is played for fluid flow tube in another road, directly is connected with high-low pressure liquid phallus 9 by high pressure liquid receiver 7, and high pressure is provided with shutoff valve 5 for fluid flow tube, can regulate open degree on demand arbitrarily, selects best liquid supply pressure.High-low pressure should and connect with same guiding for fluid flow tube, makes to enter to mix to supply the liquid communication of fluid flow tube freely suitable.Liquid level liquid body controller 8 controls of low pressure recycle bucket, opens solenoid valve 4 (YS2, YS3) in limited time on the liquid level, make two kinds of different pressures, the liquid of different temperatures and flow velocity melts mutually with the high speed rotation in mixing for the stream pipe, mixing material continued cold in the back-steam sleeve pipe, after distributing step-down, enter 1 heat absorption of many groups evaporation comb in parallel, pulled by the suction of thrust and refrigeration compressor draws, get back to low pressure recycle bucket 2, the drop that density is bigger is separated from steam, be deposited on below the container, steam is sucked back by compressor, promptly finishes a kind of refrigeration cycle process.

The utility model has following advantage compared to existing technology: powerful for hydraulic power, and can be by steaming Send out temperature system is set, compare with traditional feed liquid way, equipment manufacturing cost reduces, consumable accessory Little, highly versatile, the refrigerating efficiency height, energy consumption is low, and is simple and practical, the safety that operates steadily, The handled easily management and maintenance is set up automation control easily, is to replace the current feed flow side that falls behind The selection that formula is best.
