Description

Technical Field

[0001] This utility model relates to the field of vacuum pump application technology, and in particular to a vacuum pump suitable for high temperature and humid environments. Background Technology

[0002] In industrial production, industrial vacuum suction cups are widely used for assembling and lifting tunnel segments in humid environments and for demolding precast components on cement precast production lines. However, existing vacuum pumps have significant drawbacks when used in humid or high-temperature and humid environments. Water vapor in the air can enter the vacuum pump and mix with the pump oil, causing the pump oil to emulsify rapidly. After emulsification, the pump oil's lubrication and sealing properties decrease significantly, resulting in a lower vacuum pressure extraction value that fails to meet actual working requirements.

[0003] Meanwhile, in existing technologies, dust and impurities in the air can also enter the vacuum pump, which not only accelerates the wear of internal pump components but may also clog oil passages, further affecting the normal operation of the vacuum pump. Conventional practices do not effectively treat moisture and dust impurities in the air, relying solely on prolonged cooling and ventilation. This significantly reduces production efficiency, and the equipment lacks professional water vapor separators and proper filtration devices, directly drawing in humid air containing impurities. This causes emulsification of the pump oil, severely impacting the vacuum pump's lifespan, increasing equipment maintenance costs and downtime, and adversely affecting the continuity and stability of industrial production. Therefore, an effective solution is urgently needed to address these problems. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1, such as Figure 1-2 As shown, a vacuum pump suitable for high-temperature and humid environments includes a vacuum pump 3; an air filter 1: disposed at the front end of the air inlet of the vacuum pump 3, used to filter dust and impurities in the air; and a water vapor separator 2: disposed between the air filter 1 and the vacuum pump 3, used to separate water vapor in the air; the air outlet of the air filter 1 is connected to the air inlet of the water vapor separator 2, and the air outlet of the water vapor separator 2 is connected to the air inlet of the vacuum pump 3.

[0022] Air Filter 1: Employs a traditional air filtration structure, with its inlet connected to the outside air and its outlet connected to the inlet of the water-vapor separator. Internally, it contains filter media such as filter screens and filter cotton to intercept solid pollutants like dust and particulate matter from the air, preventing these impurities from entering the vacuum pump and causing component wear.

[0023] 2. Water vapor separator 2: such as Figure 2 As shown, the water vapor separator includes a housing 11, with an air inlet 12, an air outlet 13, and a drain outlet 14. The air inlet is connected to the air outlet of an air filter and is used to receive air from a humid or high-temperature humid environment after dust and impurities have been filtered out. The air outlet is connected to the air inlet of a vacuum pump and is used to deliver the dry air after water vapor separation to the vacuum pump 13. The drain outlet is used to discharge the separated moisture.

[0024] The housing is equipped with a separation device 15, which can be one or a combination of centrifugal separation structure, condensation separation structure, or filtration separation structure.

[0025] 3. Centrifugal Separation Structure: The shell is equipped with spiral guide vanes. After air enters the shell through the air inlet, it undergoes spiral motion under the guidance of the spiral guide vanes, generating centrifugal force. Due to the density difference between water vapor and air, under the action of centrifugal force, water droplets in the water vapor are thrown towards the inner wall of the shell and flow downwards along the inner wall, eventually being discharged from the drain outlet, while dry air enters the vacuum pump from the air outlet.

[0026] 4. Condensation and separation structure: The shell is equipped with a cooling device, such as a cooling coil. When hot and humid air enters the shell, it comes into contact with the cooling device. The water vapor in the air condenses into water droplets upon contact with the condenser. The water droplets flow downwards under the influence of gravity and are discharged from the drain outlet. The dry air then enters the vacuum pump through the air outlet.

[0027] 5. Filtration and Separation Structure: The housing contains filter elements, such as filter membranes and filter screens. These filter elements block water vapor in the air, causing it to condense into water droplets on their surface and then be discharged through the drain port. Dry air, on the other hand, passes through the filter elements and enters the vacuum pump through the outlet.

[0028] In practical applications, appropriate separation devices or combinations thereof can be selected according to specific environmental conditions (such as temperature, humidity, impurity content, etc.) to achieve the best water vapor separation effect.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment have been appropriately combined to form other embodiments that are easy for those skilled in the art to understand.
