Description

The utility model relates to water treatment, in particular to freezing devices with additional mechanical effects on water.

Known compression steam refrigeration unit, consisting of an evaporator connected via refrigerant piping to a compressor and a condenser, and a throttle valve installed on the refrigerant pipe between the evaporator and the condenser. In this case, the evaporator is also connected to the refrigerating chamber via brine pipelines (Dryzhakov E.V. et al. Technical Thermodynamics. M: Higher School, 1971).

However, this installation is not effective enough, since an enlarged compressor is required, and the cooling process is time-consuming.

The closest in technical essence to the claimed technical solution is a device for freezing water in an ultrasonic field, comprising an evaporator connected via a refrigerant piping to a compressor and a condenser, a throttle valve mounted on a refrigerant pipe between the evaporator and a condenser, and a refrigeration chamber connected to the evaporator by pipelines of brine, characterized in that it includes an ultrasonic generator associated with an electro-acoustic transducer lem located on the bottom wall of the refrigerator. The upper wall of the refrigerator is equipped with an opening for supplying water (RU 50217).

The disadvantages of this device are the inevitable loss of cooling capacity associated with the release of heat during the removal of oxygen, and the long duration of the cooling cycle, including the operation of preliminary removal of oxygen.

The technical task of the utility model is to create an effective device for freezing water and expanding the arsenal of devices for freezing water.

The technical task of the utility model is to increase cooling capacity and reduce the duration of freezing water.

The essence of the utility model is that in a device for freezing water, containing an evaporator connected via a refrigerant piping to a compressor and a condenser, a throttle valve installed on the refrigerant piping between the evaporator and a condenser, and a water cooling chamber connected to the evaporator via a brine piping and equipped with a mechanical generator in its lower part, the mechanical generator is made in the form of a generator of shock waves in the cooling chamber.

The device is configured to turn on the shock wave generator at a water temperature in the refrigerator from minus 0.5 ° C to 0.5 ° C.

In addition, the shock wave generator contains a magnetic circuit consisting of a yoke, front, middle and rear poles, as well as forward and reverse coils mounted on a non-magnetic guide, inside of which there is a ferromagnetic striker, a shock shaft and a shock absorber.

Figure 1 shows a schematic block diagram of a device for freezing water.

Figure 2 shows a schematic block diagram of a device for freezing water with a battery of generators of shock waves.

The device contains an evaporator 1, which is connected via refrigerant pipes 2 to the compressor 3 and the condenser 4. There is a throttle valve 5 installed on the refrigerant pipe 2 between the evaporator 1 and the condenser 4, by which the parameters (pressure and temperature) of the refrigerant are regulated. The refrigeration chamber 6 is connected via brine pipelines 7 to the evaporator 1. In the upper wall of the refrigeration chamber 6 there is an opening for filling with water. In the lower part of the chamber 6 is placed a generator 8 of shock waves in frozen water. To increase productivity, the device may contain several generators 8-1, 8-2, 8-3 shock waves. The device is configured to turn on the shock wave generator at a temperature of the cooled water, preferably from minus 0.5 ° C to 0.5 ° C. The temperature of the cooled water in the chamber 6 is controlled by conventional methods.

The generator can be implemented by methods known in the art, preferably the generator contains a magnetic circuit consisting of a yoke 9, front, middle and rear poles 10, 11, 12, respectively, as well as coils 13, 14 of forward and reverse, respectively, mounted on a non-magnetic guide 15. Inside it there is a ferromagnetic striker 16, a shank of the striking body 17 and a shock absorber 18, and ring frames 19 are mounted on the guide 15. Sections of coils 13, 14 are wound on them. Split punctures can be installed between layers of windings of coils 13, 14. columns (not shown) in the form of half rings made of a material with a high coefficient of thermal conductivity. These gaskets can be flanged on both sides.

To supply current pulses to the generator coils 13, 14, a thermal relay and an electric pulse generator known in the art (not shown) can be used.

The device operates as follows.

The water to be frozen is supplied to the refrigeration chamber 6. The compressor 3 is turned on, which draws refrigerant from the evaporator 1 through the refrigerant pipe 2, compresses it and delivers it to the condenser 4. In the condenser 4, the refrigerant is cooled and sent through the refrigerant pipe 2 to the throttle valve 5. Using the throttle valve 5, the refrigerant is expanded and sent through the refrigerant pipe 2 to the evaporator 1. In the evaporator 1, the refrigerant evaporates, while cooling the brine circulating through the brine pipelines 7. The cooled brine freezes water in the refrigerator 6, and when the water temperature reaches from minus 0.5 ° C to 0.5 ° C, the generator 8 turns on and creates a shock wave in the frozen water. When the generator 8 is operating under the action of current pulses supplied to the coils 13, 14, the firing pin 16 makes a movement, the shank of the shock body 17 performs a shock action on the water through the bottom of the chamber 6. The shock wave in the chamber 6 initiates the process of accelerated crystallization of supercooled water.

The use of the proposed device allows to increase the cooling capacity and reduce the duration of freezing water.
