Description

Technical Field

[0001] This utility model relates to the field of vacuum pump exhaust gas and wastewater filtration and circulation technology, specifically a vacuum pump exhaust gas and wastewater filtration and circulation device. Background Technology

[0002] A vacuum pump is a device used to create a vacuum environment by evacuating gas from a sealed container. Among the many types, the ring pump (usually referring to a ring rotary vane vacuum pump) is a common and highly efficient one. Its core function lies in the periodic change of the working chamber volume by rotating an internal eccentric rotor and sliding vanes within the ring pump chamber, thereby achieving the intake, compression, and final discharge of gas. Its working principle relies on a special vacuum oil for sealing, lubrication, and heat dissipation, and for forming the compression chamber. The operation of this type of pump requires continuous water or oil circulation and a filtration system to remove oil mist, abrasive debris, and trace contaminants generated during operation, in order to maintain oil performance, protect the precision components inside the pump body, and maintain a stable vacuum level. Simultaneously, the oil mist exhaust gas generated during operation must be effectively captured and purified by an oil mist filter (exhaust filter) before being discharged to meet environmental protection requirements and protect the working environment. Therefore, stable oil circulation, efficient oil filtration, and reliable exhaust oil mist treatment are key additional requirements for ensuring the efficient, clean, and long-life operation of ring vacuum pumps.

[0003] Because vacuum pumps need to operate at high speeds, and gas is directly drawn into the pump and discharged to complete the pumping work, while ordinary pumps do not purify the intake gas, the intake gas carrying impurities can easily cause liquid ring contamination, resulting in a reduction in the life of the device. In addition, the pump has high operating temperature requirements, and ordinary devices may not be able to meet the high-speed operation of the pump with simple heat dissipation.

The interior of the adjacent ends of the vent pipes 706 are provided with evenly distributed air holes.

[0030] Furthermore, activated carbon is fixedly connected to the upper side of the bracket 705.

[0031] Example 2:

[0032] This mechanism is used to provide water circulation filtration and cooling for water ring pump 3. This mechanism enhances the cooling intensity; please refer to [link / reference needed]. Figure 1-5 Furthermore, in conjunction with Embodiment 1, the liquid filtration and circulation mechanism 8 includes a water tank 801, which is fixedly connected to the upper surface of the base 1. A filter element 802 is fixedly connected inside the water tank 801. An exhaust pipe 803 is connected to one side of the water tank 801. A gas-liquid separator 804 is connected to the upper interior of the water tank 801. An exhaust pipe 805 is connected to the upper surface of the water tank 801 and is connected to an exhaust port 5. The gas-liquid separator 804 is connected to one end of the exhaust pipe 805. A water supply pipe 806 is connected to the lower interior of the water tank 801. A heat dissipation shroud 807 is fixedly connected to the upper surface of the base 1. A cold water rack 808 and a hot water rack 809 are fixedly connected inside the heat sink 807. The hot water rack 809 is located on the upper side of the cold water rack 808. A water supply pipe 806 is connected to the inside of the hot water rack 809. A cold water circulation port 810 is connected to one side of the cold water rack 808. Multiple heat-absorbing fins 811 are fixedly connected between the cold water rack 808 and the hot water rack 809. The heat-absorbing fins 811 are evenly distributed inside the heat sink 807. A housing 812 is fixedly connected inside the heat sink 807. A motor 813 is fixedly connected inside the housing 812. A fan blade 814 is fixedly connected to the output end of the motor 813.

[0033] Furthermore, both the cold water rack 808 and the hot water rack 809 are equipped with multiple interconnected pipes that disperse water flow.

[0034] Furthermore, the cold water circulation ports 810 are distributed on both sides of the cold water rack 808.

[0035] In actual operation, when this device is used, the user places activated carbon on the bracket 705 and screws the water bucket 704 onto the carbon box 702. Then, the user supplies water into the water bucket 704 from the water supply pipe 708, ensuring the water level covers the bottom of the inlet pipe 6. At this time, the user can connect the suction pipe 703 to the area to be pressurized. The user can then start the motor 813 and supply circulating cold water to the inside of the cold water rack 808 through the cold water circulation port 810. During the operation of the water ring pump 3, a negative pressure is generated inside the pump. The carbon box 702 is located between the suction pipe 703 and the suction pipe. The end of the suction pipe is affected by the negative pressure, sending the gas into the carbon box 702. The activated carbon adsorbs the oily and harmful gases inside the gas, and then the gas... The gas is dispersed by the vent pipe 706. The gas passes through the vent pipe 706 and removes dust and impurities from the water. Then the gas enters the water ring pump 3 and is compressed and discharged. The water in the water vapor is separated by the gas-liquid separator 804 and sent to the water tank 801. The filter element 802 inside the water tank 801 filters the water and sends it to the water inlet pipe 6. During this period, the water inside the water tank 801 is dispersed inside the hot water rack 809. The cold water rack 808 forms a heat exchange with the water flow inside the hot water rack 809 through the heat absorption fins 811. At the same time, the motor 813 drives the fan blades 814 to generate negative pressure to discharge the heat accumulated on the heat absorption fins 811. This makes the water supplied to the water inlet pipe 6 cool down in multiple ways to ensure that the water temperature is suitable for the long-term circulation operation of the water ring pump 3.
