Water circulating type cooling device of vacuum pump

The utility model relates to the carbohydrate chemical equipment field and particularly discloses a water circulating type cooling device of a vacuum pump. The water circulating type cooling device of the vacuum pump comprises the vacuum pump. The vacuum pump comprises a water inlet and a water outlet which is connected with a water storage tank; the water storage tank is connected with a water inlet of a plate type heat exchanger; a water outlet of the plate type heat exchanger is connected with the water inlet of the vacuum pump; the water storage tank is connected with a reclaimed water storage tank; the connections are pipe connections; and a filter tank is arranged between the water outlet of the vacuum and the water storage tank. The water circulating type cooling device of the vacuum pump has the advantages of achieving cyclic utilization of water and reducing water consumption due to a cooling water circulation loop of the vacuum pump and being capable of naturally cooling due to the fact that water a
