Description

Technical Field

[0001] This utility model relates to the technical field of vacuum pump sealing water purification devices, specifically a vacuum pump sealing water purification device. Background Technology

[0002] In industrial production, vacuum pumps, as critical fluid transport and negative pressure maintenance equipment, directly impact the efficiency and safety of the entire production system through their stable operation. The sealing water system, as a core auxiliary unit of the vacuum pump, plays a vital role in lubrication, cooling, and sealing the cavity. The cleanliness of the sealing water is a prerequisite for the normal operation of key components such as the vacuum pump impeller and mechanical seal. If the sealing water quality deteriorates, the solid particles and slurry impurities it contains will exacerbate component wear, clog flow channels, cause pump vibration and increased noise, and even lead to equipment shutdown, significantly increasing maintenance costs and the risk of production interruption. In existing vacuum pump sealing water systems, a single water tank is commonly used as the sealing water storage and circulation unit. However, when the gas-water separator in the system malfunctions, the medium carrying a large amount of slurry will directly enter the water tank with the sealing return water, causing rapid deterioration of the water quality inside the tank. On the one hand, solid particles in the slurry continuously wear down the internal components of the vacuum pump during circulation, shortening the equipment's service life; on the other hand, the accumulation of impurities will damage the lubrication and cooling effects of the sealing water, reduce the working efficiency of the vacuum pump, and even cause serious problems such as seal failure and cavity leakage. Traditional methods rely heavily on manual, periodic water changes and tank cleaning, which is not only labor-intensive but also fails to prevent impurities from entering the system in real time, resulting in limited water quality improvement. Furthermore, the lag in manual operation can cause the sealing water to remain contaminated for extended periods, creating a vicious cycle that severely restricts the stability and economy of the production system.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] like Figure 1 As shown in the figure, the vacuum pump sealing water purification device provided in this embodiment includes a circulation tank 1, a water supply pump 7 connected to one side of the lower end of the circulation tank 1, a water supply pipe 8 connected to the end of the water supply pump 7 away from the circulation tank 1, an overflow pipe 3 provided above the circulation tank 1, a sedimentation tank 2 connected to the end of the overflow pipe 3 away from the circulation tank 1, a return water pipe 9 provided above the sedimentation tank 2, a vacuum pump provided on the return water pipe 9, and a Y-type filter provided in front of the vacuum pump.

[0026] Understandable, Figure 1 This illustration only schematically shows some components of a vacuum pump-sealed water purification device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, a vacuum pump-sealed water purification device can also include, compared to... Figure 1 More or fewer parts.

[0027] In this embodiment, the height difference between the circulation tank 1 and the sedimentation tank 2 satisfies the requirement that the hydraulic slope of the overflow pipe is ≥0.005, ensuring smooth water flow. The volume design of the sedimentation tank 2 strictly follows the principle of return water volume × sedimentation time, i.e., based on the actual return water volume (unit: m³) of the vacuum pump return water pipe. 3 The sedimentation time is calculated based on a 30-60 minute settling time to ensure sufficient residence time for the slurry in the sedimentation tank to complete solid-liquid separation. This prevents insufficient sedimentation due to excessive water volume and slurry backflow through the overflow pipe. Sedimentation tank 2 utilizes the principle of high-level gravity sedimentation, receiving return water discharged from the vacuum pump through return water pipe 9. The denser slurry settles in the tank, while the clear water on the surface flows back to the circulation system through overflow pipe 3. The lower edge of overflow pipe 3 is 50-100 cm below the top of sedimentation tank 2. The Y-type filter in front of the vacuum pump has a precision of 100μm, which can pre-filter large particulate impurities in the return water, reducing the amount of slurry entering the sedimentation tank. The pre-treatment in the sedimentation tank prevents the slurry from directly entering the circulation tank, reducing the turbidity of the sealing water. The Y-type filter reduces impurities at the source, and together with the overflow circulation, it achieves continuous purification of the sealing water, improving the stability of the vacuum pump operation.

[0028] Specifically, a drain valve 5 is installed on the side of the circulating tank 1 away from the water pump 7, a drain valve 6 is installed at the lower end of the side of the sedimentation tank 2 away from the overflow pipe 3, and a baffle 4 is installed inside the sedimentation tank 2.

[0029] In this embodiment, the drain valve 5 of the circulation tank 1 is used to discharge a small amount of impurities deposited at the bottom of the tank; the drain valve 6 of the sedimentation tank 2 periodically discharges the sludge settled at the bottom of the tank; the baffle 4 forms a flow channel in the sedimentation tank, extending the water flow path and promoting full sedimentation of the slurry; the dual drain valves are set up to handle impurities in the circulation tank and the sedimentation tank respectively, avoiding the accumulation of impurities that affect water quality; the baffle enhances the sedimentation effect and improves the solid-liquid separation efficiency; at the same time, the turbidity, pH and suspended solids content of the sealed water in the circulation tank 1 are manually tested every week, and the sedimentation effect of the sedimentation tank 2 is checked in time when the standards are exceeded.

[0030] Specifically, a large-diameter ball valve is installed on the drain valve 26, and a backwash port is installed on the front side of the large-diameter ball valve.

[0031] As a preferred implementation method, the second drain valve 6 adopts a large-diameter ball valve of DN50-DN80 to ensure smooth discharge of sludge; the backwash port in front of the valve can be filled with compressed air or clean water to flush the pipe wall during sewage discharge, preventing sludge from sticking and clogging the valve port. The large-diameter ball valve improves sewage discharge efficiency, and the backwash function solves the problem of sludge adhesion, reduces the frequency of valve maintenance, and ensures long-term smooth operation of the sewage discharge system.

[0032] Specifically, a turbidity meter and a level gauge are installed inside the sedimentation tank 2 at a height of one-third from the bottom of the tank, and an inclined plate sedimentation device with an inclination angle of 60° is installed above the bottom of the sedimentation tank 2.

[0033] It should be noted that the turbidity meter and level gauge located one-third of the height from the bottom of the sedimentation tank 2 monitor the water quality and level in real time. When the turbidity exceeds the set value or the level is abnormal, the drain valve 26 is automatically triggered to open. The inclined plate sedimentation device with a 60° inclination above the bottom of the tank increases the settling area and accelerates the agglomeration and settling of slurry particles. Intelligent monitoring enables precise sewage discharge. The inclined plate device improves sedimentation efficiency and prevents slurry from entering the circulation tank with the overflow pipe, ensuring the stability of the sealing water quality. At the same time, the sewage discharge cycle is set according to the turbidity monitoring data of the turbidity meter to ensure that the sludge at the bottom of the tank is fully discharged. The inclined plate, filter screen and drain valve inside the sedimentation tank 2 are disassembled and inspected every quarter to clean the adhering sludge.

[0034] Specifically, a filter screen is installed at the connection between the overflow pipe 3 and the sedimentation tank 2, a float valve is installed on the circulation tank 1, and a high and low water level alarm sensor is installed inside the circulation tank 1.

[0035] As a preferred implementation, a detachable filter screen with an aperture of 0.5-1mm is used at the connection between the overflow pipe 3 and the sedimentation tank 2 to intercept floating oil and fine particles; the float valve of the circulation tank 1 controls water replenishment, and the high and low water level alarm sensor triggers an alarm when the float valve fails, preventing abnormal water level from affecting the operation of the vacuum pump. The filter screen further purifies the overflow water quality. The float valve and the alarm sensor work together to achieve automatic water level control and abnormal early warning, improving the safety of the system.

[0036] Example 2:

[0037] Specifically, the float valve is made of stainless steel and adopts a dual-valve redundancy configuration consisting of a main valve and a backup valve.

[0038] It should be noted that the stainless steel float valve has strong corrosion resistance, and the dual-valve redundancy setting ensures reliable water replenishment. When the main valve fails, the backup valve automatically starts to prevent water shortage in the circulation tank. The stainless steel material extends the service life of the float valve, and the dual-valve redundancy setting reduces the risk of downtime due to valve failure, ensuring the stability of the water replenishment system. At the same time, the float valve is tested for sealing performance every year to prevent valve aging and leakage.

[0039] Specifically, a filter is installed on water supply pipe 8, and an emergency water supply valve is also installed on water supply pipe 8.

[0040] In this embodiment, a filter with a precision of 50-100μm on the water supply pipe 8 filters impurities in the makeup water to prevent clogging of the float valve; the emergency makeup water valve is linked with the drain valve and opens during draining to ensure that the makeup water flow rate is ≥ 1.5 times the drain flow rate, thus avoiding a sudden drop in the water level of the circulation tank. The filter protects the float valve from being blocked by impurities, and the emergency makeup water valve maintains a stable water level in the circulation tank during draining to prevent the vacuum pump from being damaged due to lack of water, thereby improving the system's resilience.

[0041] When in use, if the steam-water separator malfunctions and causes slurry to mix into the sealing water, the newly added sedimentation tank 2 high-level water tank uses the principle of gravity sedimentation to first receive the vacuum pump return water, causing the denser slurry to settle at the bottom of the tank, while the clear water on the surface returns to the circulation pipe through the overflow pipe. Through physical separation, the accumulation of impurities in the circulation tank 1 is reduced, thereby improving the quality of the sealing water.

[0042] Finally, it should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
