[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1 The utility model provides a technical solution: an industrial sewage cooling recrystallization recovery device.

[0025] Among them, a condenser 2 is arranged inside the insulated box 1, a cooling device 3 is arranged at the center of the condenser 2, support columns 102 are fixedly connected at the four corners of the top and bottom of the insulated box 1, a collecting box 4 is arranged below the support columns 102 at the bottom of the insulated box 1, a water inlet pipe 201 is arranged on the top of the condenser 2, a water outlet pipe 202 is arranged at the bottom of the condenser 2, a cover plate 401 is arranged on the top of the collecting box 4, a water inlet is opened at the lower left corner of the cover plate 401, a drainage hole 402 is opened at the lower right corner of the bottom of the collecting box 4, docking rings 403 are arranged at the four corners of the bottom of the collecting box 4, a partition 404 is fixedly connected near the right side of the center position inside the collecting box 4, a filter screen 405 is arranged on the back of the partition 404, and a temperature sensor 101 is installed on the front of the insulated box 1.

[0026] In this embodiment, the heat preservation box 1 is filled with coolant, and the condenser 2 is immersed in the coolant. The condenser 2 descends in a spiral shape, so that the flow path of the sewage in the heat preservation box 1 is greatly lengthened, and the sewage can be fully contacted with the coolant to cool down. The cooling device 3 is arranged in the middle position of the heat preservation box 1, and the top extends from the heat preservation box 1. The external power supply is used for power supply. The sewage enters from the water inlet pipe 201 of the condenser 2 and flows in the condenser 2. The temperature of the condenser 2 is reduced by the coolant. The condenser 2 absorbs the temperature of the sewage, so that the temperature of the sewage decreases. After the coolant absorbs the temperature, the temperature rises. At this time, the cooling device 3 starts to cool the coolant. The coolant in the heat preservation box 1 is always kept at a constant temperature. The operator can adjust the temperature in the heat preservation box 1 through the temperature sensor 101. As the temperature of the sewage drops, the compounds in the sewage are precipitated into crystals, which pass through the water inlet through the outlet pipe and enter the collection box 4. The partition 404 in the collection box 4 divides the interior of the collection box 3 into two parts. The sewage must pass through the filter screen 405 between the partition 404 and the side wall of the collection box 4 and then enter the drain hole 402 for discharge. The crystals cannot pass through the filter screen 405 and are retained on the side of the partition 404. When all the sewage is discharged, the collection box 4 is removed and the cover is opened to take out the crystals in the collection box 4.

[0027] The heat preservation boxes 1 and the collection boxes 4 can be stacked in groups.

[0028] In this embodiment, the support column 102 of the insulation box 1 can be inserted into the docking ring 403 on the surface of the collection box 4, so as to fix the insulation box 1 and the collection box 4. The insulation box 1 has support columns 102 on the top and bottom, and the collection box 4 has docking rings 403 on the top and bottom, so that the collection box 4 can be installed on the top and bottom of the insulation box 1, and the insulation box 1 can be installed on the top and bottom of the collection box 4. The water outlet pipe 202 of the condenser 2 in the insulation box 1 is aligned with the water outlet on the cover plate 401 of the collection box 4, and the drainage hole 402 at the bottom of the collection box 4 is aligned with the water inlet pipe 201 of the condenser 2. Multiple insulation boxes 1 and collection boxes 4 are stacked, and the coolant temperature in each insulation box 1 is distinguished. The temperature decreases from top to bottom, so that different types of compounds precipitated at different temperatures can be distinguished, which is convenient for subsequent classification.

[0029] There are three support columns 102 at the top and bottom of the insulated box 1 , respectively. The water inlet pipe 201 is located at the lower right corner of the top of the insulated box 1 , and the water outlet pipe 202 is located at the lower left corner of the bottom of the insulated box 1 .

[0030] In this embodiment, the drainage hole 402 is set in the docking ring 403, the water inlet pipe 201 is inserted into the docking ring 403 to dock with the drainage hole 402, and the remaining support columns 102 are fixed in position by the docking ring 403. The water inlet pipe 201 and the support columns 102 are symmetrically located at the four corners of the insulation box 1, and the overall appearance is beautiful and not abrupt.

[0031] The filter screen 405 is located at the far end of the water inlet and the drain hole 402 .

[0032] In this embodiment, after entering from the water inlet, the sewage needs to pass through half of the collection box 4 and contact the filter screen 405 for filtration, so that the collection box 4 can store more crystals.

[0033] A visible window 406 is provided on the back side of the collection box 4, located on one side of the water inlet.

[0034] In this embodiment, transparent glass is installed on the viewing window 406 , and the operator can see the crystallization situation inside the collection box 4 through the viewing window 406 .

[0035] The drainage hole 402 needs to be connected to other collection devices.

[0036] In this embodiment, the wastewater after recrystallization may contain other pollutants, so the wastewater after recrystallization still needs to be collected and stored to prevent environmental pollution.

[0037] Working principle: sewage enters from the water inlet pipe 201 of the condenser 2, flows in the condenser 2, and the temperature of the condenser 2 is lowered by the coolant. The condenser 2 absorbs the temperature of the sewage, causing the sewage temperature to drop, and the compounds in the sewage are precipitated into crystals. The sewage passes through the water inlet through the outlet pipe and enters the collecting box 4. The sewage passes through the filter 405 and then enters the drain hole 402 for discharge. The precipitated crystals cannot pass through the filter 405 and are retained on the side of the partition 404. When all the sewage is discharged, the collecting box 4 is removed and the cover is opened to take out the crystals in the collecting box 4. By arranging multiple groups of insulation boxes 1 and stacking the collecting boxes 4, the coolant temperature in each insulation box 1 is distinguished, and the temperature decreases from top to bottom, so that different types of compounds precipitated at different temperatures can be distinguished, which is convenient for subsequent classification.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
