Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchange equipment technology, specifically a heat pump system for cooling a vacuum pump. Background Technology
[0002] During beer bottling, vacuum pumps are used to create a vacuum in the containers to extend the beer's shelf life and maintain its original flavor. Currently, these vacuum pumps are primarily water-cooled, which is uneconomical given the increasing scarcity of water resources. Furthermore, the heat generated by the vacuum pumps is not utilized, resulting in a waste of thermal resources. Meanwhile, factory production lines use large amounts of steam for heating in bottle washing and sterilization machines, requiring additional heat. Therefore, how to deliver the hot water generated by the vacuum pumps to these heat-requiring workstations, such as bottle washing machines, is an important research direction for energy conservation, emission reduction, and cost reduction.

[0022] Please see Figure 1-3 This utility model provides a heat pump system for cooling a vacuum pump, including a vacuum pump cooling water circuit, a heat pump 20, a plate heat exchanger 30, and a bottle washing machine prepreg tank 40.
[0023] The vacuum pump cooling water circuit includes a vacuum pump cooling water tank 11 and a circulating pump 12. The inlet of the circulating pump 12 is connected to the vacuum pump cooling water tank 11 through a pipe.

The drain outlet of the circulating pump 12 is connected to the heat pump hot inlet 21 through a pipe, and the heat pump hot outlet 22 is connected to the vacuum pump cooling water tank 11 through a pipe. The cooling water in the vacuum pump cooling water tank 11 exchanges heat on the evaporator side of the heat pump 20. The cooling water cooled by the evaporator side of the heat pump flows back to the vacuum pump cooling water tank 11.
[0025] The plate heat exchanger 30 is equipped with a plate heat exchange inlet 31, a plate heat exchange outlet 32, a plate cold inlet 33, and a plate cold outlet 34. The plate heat exchange inlet 31 is connected to the heat pump cold outlet 24 through a pipe. A circulation pump 25 is installed between the plate heat exchange inlet 31 and the heat pump cold outlet 24. The plate heat exchange outlet 32 is connected to the heat pump cold inlet 23 through a pipe. The plate cold inlet 33 and the plate cold outlet 34 are respectively connected to the bottle washing machine pre-impregnation tank 40 through pipes.
[0026] A circulating pump 41 and a filter 42 are installed between the pre-impregnation tank 40 and the plate heat exchanger inlet 33 of the bottle washing machine. The filter 42 includes a body 421, a top cover 422, a perforated plate 423, and a filter element 424. A bottom support plate 425 is installed inside the body 421. The bottom support plate 425 has multiple holes. A grooved pad 426 is installed on the upper surface of the bottom support plate 425. A water inlet pipe 427 is installed on the side of the body 421.

[0027] The working principle of this utility model is as follows:
[0028] The circulating pump 12 draws water from the vacuum pump cooling water tank 11 and delivers it to the evaporator side of the heat pump 20 for heat exchange. The cooled water then flows back to the vacuum pump cooling water tank 11, and the cycle continues.
[0029] Water from the plate heat exchanger 30 enters the condenser side of the heat pump 20 via the plate heat exchanger inlet and the second circulation pump for heat exchange. The heated water exchanges heat with the bottle washing machine pre-soaking tank 40 (or sterilizer) and then flows back from the plate heat exchanger outlet to the condenser side of the heat pump 20, thus circulating.
[0030] The circulating pump 41 draws water from the pre-impregnation tank 40 of the bottle washing machine, passes through the filter 42, and enters the plate heat exchanger inlet 33. After absorbing heat, the water flows back to the pre-impregnation tank 40 from the plate heat exchanger outlet 34, and the cycle continues.
