Description

Technical Field

[0001] The utility model belongs to the field of refrigeration equipment, and more specifically relates to a descaling device for central air-conditioning cooling equipment. Background Art

[0002] Central air conditioning cooling equipment is generally a cooling tower, which uses water as a circulating coolant, absorbs heat from the system and discharges it into the atmosphere to reduce the water temperature. Its cooling is to use the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer and radiation heat transfer. The waste heat generated in industry or refrigeration and air conditioning is dissipated to reduce the water temperature through the evaporative heat dissipation device to ensure the normal operation of the system.

[0003] The existing cooling tower is provided with a water collecting tank at the bottom. Due to factors such as water quality, a large amount of scale will be formed on the inner wall of the water collecting tank after long-term use. The descaling device can remove the scale on the inner wall. The descaling device is composed of a water collecting tank, a tower body, a connecting column, a drain pipe, a filler, a pipe, a nozzle, a water remover, a No. 1 motor, a fan blade, a discharge groove, a mounting groove, a No. 2 motor, a mounting ring, an L-shaped rod and a brush. When the central air-conditioning cooling equipment is in use, the pipe on the tower body is connected to the external water pipe, and the cooling water carrying waste heat is sent into the pipe by a water pump, and the No. 1 motor and the water remover are started to drive the fan blade to rotate, and then the water is sprayed to the filler by the nozzle, and finally the water temperature is reduced and drips into the water collecting tank at the lower end of the connecting column. When it is necessary to remove the scale in the water collecting tank, the No. 2 motor in the mounting groove is started to rotate the mounting ring, and the L-shaped rod and the brush are driven to rotate, so as to scrape off the scale on the bottom and side wall of the inner wall of the water collecting tank, and finally the scale is discharged from the discharge groove and the drain pipe.

[0004] The inventor found in his daily work that during use, cooling water carrying waste heat is sprayed out through the nozzle to the filler, and then drips into the water collecting pool. After long-term use, the water collecting pool will have scale attached to the inner wall. If the scale is not removed in time, the scale will accumulate, causing the water storage in the water collecting pool to decrease. The scale on the inner wall of the water collecting pool can be removed by driving a brush with a motor. Since the bristles on the brush are in contact and friction with the inner wall for a long time, the bristles are worn, which in turn affects the removal of scale. Utility Model Content
