Description of the drawings:

fig. 1 is a schematic structural diagram relating to the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1, a freezing agitator tank has a jar body 1, be equipped with by gear motor 10 driven agitator 2 in jar body 1, jar body 1 top sets up water inlet 11, the inner wall winding of jar body 1 has heating pipeline 3 and refrigerating pipeline 4, and heating pipeline 3 should dispose the valve with refrigerating pipeline 4, and heating pipeline 3 and the crisscross winding of refrigerating pipeline 4, make jar body 1 all reach the purpose of even heat exchange when refrigerating or heating. Because the heating is only used for melting the crystals, the heating pipeline 3 can be externally connected with exhaust of other equipment for waste heat utilization, and the refrigerating pipeline 4 can be externally connected with a compressor and the like, so that the heat exchange speed is higher.

The outer wall of the tank body 1 is wrapped with a heat insulation layer 9, and the heat insulation layer 9 can be made of asbestos, silicate, a vacuum plate and the like, so that heat exchange between the tank body 1 and the outside is avoided.

The bottom of the tank body 1 is provided with an inclined opening 5, a sealing valve 51 is arranged at the inclined opening 5, after 3-4 times of heat exchange, the residual crystal generally contains 90% -95% of impurities, and therefore the sealing valve 51 can be opened to directly remove the crystal.

Jar body 1 is equipped with first drain port 6 in slope opening 5 one side, and first drain port 6 is equipped with filter screen 61 and valve 62, and when accomplishing the crystallization process at every turn, agitator 2 stops the action, and valve 62 is opened, and the water that does not crystallize is direct to be discharged from drain port 6, and filter screen 61 then blocks small-size crystal and flows along with water.

Further, storage water tank 7 in the middle of first drain 6 passes through the pipe connection, and middle storage water tank 7 connects suspension analyzer 74, and suspension analyzer 74 can adopt bell analyzer, detects whether quality of water is up to standard, if not up to standard, and middle storage water tank 7 bottom is through being equipped with backward flow mouth 72, and backward flow mouth 72 is through pipeline and water pump with water pumpback to water inlet 11 department to get into jar repeated crystallization scrubbing process in 1 again. The intermediate water tank 7 is provided with a second water outlet 71 at the upper part thereof, the intermediate water tank 7 corresponds to a settling tank, even if some suspended particles exist, the suspended particles can flow back through the return port 72 by settling, the upper clear liquid is discharged from the second water outlet 71, and the second water outlet 71 should be provided with a valve.

Preferably, the tank body 1 is further provided with a temperature sensor 81 and a liquid level sensor 82, the temperature sensor 81 is used for detecting the crystallization state of the liquid in the tank body 1 for real-time feedback, which is beneficial to operating the speed reduction motor 10, the heating pipeline 3 and the refrigeration pipeline 4 to open and close valves, and the liquid level sensor 82 can detect the highest liquid level amount, so that the liquid in the tank body 1 keeps a proper water level.

When the utility model is implemented, sewage to be treated is put in through the water inlet 11 under the control of the liquid level sensor 82, then the refrigeration pipeline 4 is opened to refrigerate the tank body 1, the stirrer 2 is combined to lead the sewage in the tank body 1 to carry out rapid heat exchange for crystallization, under the action of the temperature sensor 81, when the water approaches the primary crystallization state, the stirring and refrigeration are stopped, the first water discharge port 6 is opened to discharge the water which is not crystallized, then hot air or hot water is introduced into the heating pipeline 3 to heat the tank body 1 for melting crystals, when the temperature of the tank body 1 rises until crystals are dissolved, the heating can be stopped when the temperature generally rises by 2-3 ℃, then the refrigeration is repeated, the crystallization and the drainage are repeated, the process is circulated for 3-4 times, the pollutants can be effectively separated, and the residual ice crystals containing a large amount of pollutants are directly discharged by opening the sealing valve 51 for secondary treatment.

The valves can adopt electromagnetic valves.

It is to be understood that the technical scope of the present invention is not limited to the content of the specification, and that modifications or changes may be made by those skilled in the art based on the above description, and all such modifications and changes are intended to fall within the scope of the appended claims.
