Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning, in particular to a central air-conditioning circulating water synchronous dosing device. Background Art

[0002] A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. Unlike traditional refrigerant air conditioning, this system centrally processes air to achieve comfort requirements. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment. When the central air conditioning unit is in operation, the circulating water circulates through the refrigeration unit, circulation pipes, and cooling tower. In order to prevent the circulating water from exceeding the water quality standard, the circulating water system needs to be treated with chemicals, which requires the use of a chemical treatment device.

[0003] However, most existing dosing devices are not equipped with filtering devices when in use, so that impurities in the circulating water and a large amount of foam generated when mixing drugs enter the interior of the air conditioner, causing large losses when the air conditioner is used for a long time. In addition, when the existing central air conditioning dosing box discharges the circulating water, the water will adhere to the inner wall of the box, causing waste of drugs and easily corroding the inner wall of the box. Utility Model Content

[0004] In order to solve the problem that most existing dosing devices are not equipped with filtering devices when in use, and the existing central air-conditioning dosing box will adhere to the inner wall of the box when discharging circulating water, causing waste of medicine and easily corroding the inner wall of the box; the purpose of this utility model is to provide a central air-conditioning circulating water synchronous dosing equipment.

[0005] The evaporation filter cloth is fixed on the evaporation filter cloth, and the evaporation filter cloth is fixed on the evaporation filter cloth, and the evaporation filter cloth is fixed on the evaporation filter cloth.

[0006] Preferably, the inside of the box is provided with two symmetrically distributed second scrapers, two sides of the two second scrapers are fixedly installed with two symmetrically distributed second sleeve rods, one side of the four second sleeve rods is slidably sleeved with a first sleeve rod, one side of the four first sleeve rods is fixedly installed on the outer surface of the rotating shaft, the middle part of the four second sleeve rods is fixedly installed with a spring, and the other end of the four springs is fixedly installed on one end of the connecting rod.

[0007] Compared with the prior art, the utility model has the advantages that:

[0008] 1、The application can filter circulating water and circulating water after adding medicine, filter impurities in the circulating water and a large amount of foam generated by mixed medicine, so that the impurities are removed when the circulating water flows into the air conditioner again, thereby reducing the wear of the equipment and prolonging the service life of the equipment.

[0009] 2、The application can remove the liquid attached to the inner wall of the box, thereby improving the use effect of the circulating water and avoiding the long-term retention of the medicine on the inner wall of the box, which causes corrosion to the inner wall of the box.
