Description

Technical Field

[0001] This application relates to the field of vacuum equipment, and more specifically, to a simple vacuum water circulation device. Background Technology

[0002] Vacuum water circulation is a highly efficient, energy-saving, and widely used water resource utilization technology. By using a vacuum pump to create a negative pressure environment in a closed system, water automatically circulates under the action of pressure difference without the need for additional power. This technology not only significantly reduces water consumption and scale buildup and maintenance costs, but also stably maintains a high vacuum level, meeting the stringent requirements of vacuum distillation, drying, and other processes in the chemical, pharmaceutical, and food processing industries. It is widely used in industrial production, laboratory research, and civilian applications.

[0003] However, many traditional water circulation devices typically use only a single-layer filter. This single-layer filter cannot effectively filter impurities of different particle sizes in the water. Larger particles may clog the filter and affect water flow, while small particles may not be effectively intercepted, resulting in the circulated water still containing a lot of impurities. This cannot meet the requirements of processes or applications with high water quality requirements, such as chip cleaning in the electronics industry or solution preparation in the pharmaceutical field. Therefore, this application proposes a simple vacuum water circulation device. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to provide a simple vacuum water circulation device to address the shortcomings of existing technologies and solve the problem of poor water filtration in existing vacuum water circulation devices.

[0006] To achieve the above objectives, this application provides the following technical solution: A simple vacuum water circulation device includes a base, a vacuum water pump and a circulating water tank mounted on the top of the base, a filter box inside the circulating water tank, an inlet pipe connected to the inlet of the vacuum water pump and communicating with the bottom of the circulating water tank, a return pipe connected to the exhaust port of the vacuum water pump, and the other end of the return pipe extending into the filter box inside the circulating water tank, a through groove opened on the bottom wall of the filter box, a lower filter plate and an upper filter plate arranged at the bottom of the filter box, the lower filter plate being located below the upper filter plate, activated carbon being laid between the lower and upper filter plates, and the filtration mesh number of the upper filter plate being smaller than that of the lower filter plate.

[0007] Furthermore, the activated carbon is contained in a gauze bag and laid out.

[0008] Furthermore, a second control valve is installed on the water inlet pipe, and a drain pipe is provided at the bottom of the side wall of the circulating water tank, with a first control valve installed on the drain pipe.

[0009] Furthermore, a cover plate is provided at the top of the circulating water tank, and a handle is provided on the cover plate.

[0010] Furthermore, a second adapter groove is provided at the end of the cover plate facing the vacuum water pump, and the return water pipe extends from top to bottom through the second adapter groove into the water filter box, with the second adapter groove penetrating the end face of the cover plate.

[0011] Furthermore, the filter box is movably disposed inside the circulating water tank, and the filter box can move away from the vacuum water pump. A first adapter groove is provided on the top of the side wall of the filter box facing the vacuum water pump.

[0012] Furthermore, a raised strip is provided on the top of the inner wall of the circulating water tank, and an outwardly protruding edge plate is provided on the top of the side wall of the filter box, with the edge plate sliding against the raised strip.

[0013] The beneficial effects of this application are as follows: By employing a filtration structure combining a double-layer filter plate and activated carbon, impurities in the water can be filtered in stages, first intercepting larger particles and then filtering out finer particles. The activated carbon effectively adsorbs odors and pigments in the water, improving the water purification effect and ensuring the cleanliness of the water used in recycling.

[0014] By placing the filter box within the circulating water tank, when the activated carbon needs to be replaced or the filter plates cleaned, simply move the filter box. The return water pipe passes through the first adapter slot without interfering with operation. The filter box can be directly removed from the circulating water tank, making it convenient, quick, and reducing maintenance costs. The overall structure is simple and compact, occupies little space, and is easy to maintain. Attached Figure Description

[0022] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-5As shown, this utility model provides a simple vacuum water circulation device, including a base 1, a vacuum water pump 2, a circulating water tank 3, and a filter box 10. The vacuum water pump 2 and the circulating water tank 3 are installed on the top of the base 1. A cover plate 7 is provided on the top of the circulating water tank 3, and a handle 15 is provided on the cover plate 7 for easy access by the operator. In addition, a second adapter groove 14 is also provided on the cover plate 7. The filter box 10 is movably disposed inside the circulating water tank 3.

[0024] In this embodiment, the vacuum water pump 2 has a water inlet, an exhaust outlet, and an air extraction outlet (the water inlet, exhaust outlet, and air extraction outlet are the structure of an existing vacuum pump). The water inlet of the vacuum water pump 2 is connected to an inlet pipe 8, which communicates with the bottom of the circulating water tank 3. A second control valve 9 is installed on the inlet pipe 8 to control the water flow rate. The exhaust outlet of the vacuum water pump 2 is connected to a return water pipe 4. The other end of the return water pipe 4 passes from top to bottom through the second adapter groove 14 on the cover plate 7 and extends into the filter box 10 installed inside the circulating water tank 3. The second adapter groove 14 penetrates the end face of the cover plate 7. This ensures that the removal and placement of the cover plate 7 are not interfered with by the return water pipe 4.

[0025] Furthermore, in this embodiment, a through groove 16 is provided on the bottom wall of the water filter box 10. Water discharged from the return water pipe 4 enters the water filter box 10 and can flow through the through groove 16 to the circulating water tank 3 for recycling. A lower filter plate 17 and an upper filter plate 19 are provided at the bottom of the water filter box 10. The lower filter plate 17 is located below the upper filter plate 19, and the filter mesh number of the upper filter plate 19 is smaller than that of the lower filter plate 17. Activated carbon 18 is laid between the lower filter plate 17 and the upper filter plate 19. The activated carbon 18 is placed in a gauze bag for easy replacement and maintenance, and is used to filter the return water.

[0026] In this embodiment, a drain pipe 5 is provided at the bottom of the side wall of the circulating water tank 3, and a first control valve 6 is installed on the drain pipe 5 for draining water from the circulating water tank 3 to facilitate cleaning of the circulating water tank 3. A filter box 10 is movably disposed within the circulating water tank 3 and can move away from the vacuum water pump 2. A first adapter groove 13 is provided on the top of the side wall of the filter box 10 facing the vacuum water pump 2. When the filter box 10 needs to be moved, the return water pipe 4 can pass through the first adapter groove 13 to avoid interfering with the movement of the filter box 10. Furthermore, a raised strip plate 12 is provided on the top of the inner side wall of the circulating water tank 3, and an outwardly protruding edge plate 11 is provided on the top of the side wall of the filter box 10. The edge plate 11 slides against the raised strip plate 12, enabling the filter box 10 to be movably disposed within the circulating water tank 3.

[0027] Working Principle: In this simple vacuum water circulation device, clean water is injected into the circulating water tank 3, and the vacuum water pump 2 is started. The air extraction port of the vacuum water pump 2 is connected to the equipment to be evacuated, and a vacuuming operation is performed. Simultaneously, the vacuum water pump 2 draws clean water from the circulating water tank 3 into itself through the water inlet pipe 8, forming an eccentric water ring. As the vacuum water pump 2 continues to work, the air inside the equipment to be evacuated is gradually extracted, creating a negative pressure environment. The air and excess water inside the vacuum water pump 2 are discharged through the exhaust port and the return water pipe 4 into the filter box 10. The discharged air disperses freely, and the discharged water falls into the filter box 10. After entering the filter box 10, it flows into the bottom of the circulating water tank 3 through the through groove 16 on the bottom wall of the filter box 10, forming a water circulation. During this process, when the water flows into the filter box 10 from the return water pipe 4, it first undergoes preliminary filtration through the upper filter plate 19, which can intercept larger particles of impurities in the water. Next, water flows into the activated carbon 18 layer between the upper filter plate 19 and the lower filter plate 17. Activated carbon 18 has a strong adsorption capacity, which can adsorb odors, pigments, and small particles in the water, further purifying the water quality. Finally, the water filtered by activated carbon 18 undergoes a second filtration through the lower filter plate 17, which can filter out even finer impurities, ensuring the cleanliness of the water used in circulation. When it is necessary to drain and clean the circulating water tank 3, the first control valve 6 on the drain pipe 5 is opened, and the water in the circulating water tank 3 can be discharged through the drain pipe 5, allowing the circulating water tank 3 to be cleaned.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
