Description

Technical Field

[0001] The utility model relates to the technical field of filling, discharging and vacuum pumping equipment, in particular to a filling, discharging and vacuum pumping device. Background Technique

[0002] Oxygen is a colorless, odorless and tasteless gas and is one of the common elemental gases. Oxygen plays a crucial role in many biological and chemical processes. During the process of evacuating and then filling the tank, the pressure inside the tank will change, causing water droplets to form inside the tank. In some tanks, during the repeated filling, discharging and vacuum pumping process, the amount of water inside the tank will increase, resulting in a decrease in the volume of the gas filled in the tank, and the corrosion of the tank by the water droplets will pose a safety hazard.

[0003] According to a disclosed filling, discharging and vacuum pumping device for helium production (Publication No.: CN217464069U), at the position on the outer wall of the vacuum pump corresponding to the bottom end of the gas tank, a support plate is fixedly installed, a drain pipe is fixedly installed on the support plate, an extension pipe is fixedly installed at the bottom of the gas tank, and the bottom end of the extension pipe is correspondingly clamped inside the drain pipe. A flapping device is arranged at the position on the outer wall of the vacuum pump corresponding to the gas tank.

[0004] However, during the actual use of the above-mentioned vacuum pumping device, the force of the flapping device is mainly concentrated at the position where the flapping plate contacts the gas tank, and the vibration of the flapping is difficult to effectively transmit to other positions of the gas tank, which results in uneven effect of removing water droplets by flapping, and some water droplets may not receive enough force to make them break away from the inner wall. In view of this, we propose a filling, discharging and vacuum pumping device. Content of the Utility Model

[0017] Compared with the prior art, the utility model provides a filling, draining and vacuuming device, which has the following beneficial effects:

[0018] 1. The filling, discharging and vacuuming device, through the arranged driving gear, gear ring, cam and sealing ring, the gas tank rotates, and the water droplets have a certain rotational inertia when the gas tank rotates. The centrifugal force throws the water to the inner wall of the tank body, reducing the contact area between the water droplets and the surface of the tank body, thereby weakening the adhesion of the water droplets, making it easier to shake off the water droplets. The cam knocks the outer wall of the gas tank, and this vibration disturbs the rotational inertia of the water droplets attached to the tank wall, so that the water droplets are shaken off. At the same time, the vibration generated by the knocking during the rotation is evenly distributed around the gas tank, rather than concentrated in a certain place, so that the water droplets on various places on the inner wall of the tank body are shaken off more effectively. The spring pushes the sealing ring to always abut against the inner ring, thereby improving the sealing degree between the outer ring and the inner ring, improving the sealing degree of the water drop removal component, and then improving the airtightness during vacuuming, and improving the efficiency of vacuuming.

[0019] 2. In this filling, discharging, and vacuum pumping device, during the rotation of the inner ring, the grease is evenly applied to the upper surface of the inner ring through the arranged grease, reducing the direct friction between them, reducing the wear of the sealing ring and the inner ring, and extending the service life of the seal.

A mounting frame 5 is fixedly connected to the side wall of the vacuum pump 1. The mounting frame 5 is sleeved with a gas tank 6. A water droplet removing component is arranged on the side wall of the vacuum pump 1. The water droplet removing component includes an outer ring 7, a sphere 8, an inner ring 9, a rubber ring 10, an L-shaped ring 11, a seal ring 12, a spring 13, a motor 14, a rotating shaft 15, a driving gear 16, a ring gear 17, a reduction gearbox 18, a rotating rod 19, a cam 20, and grease 21.

[0027] In one embodiment of the utility model, the side wall of the vacuum pump 1 is fixedly connected to a motor 14, the output end of the motor 14 is fixedly connected to a rotating shaft 15, the side wall of the rotating shaft 15 is fixedly connected to a driving gear 16, the side wall of the gas tank 6 is fixedly connected to a ring gear 17, the driving gear 16 is meshed with the ring gear 17, the rotation of the rotating shaft 15 drives the driving gear 16 to rotate, the rotation of the driving gear 16 drives the ring gear 17 and the gas tank 6 to rotate, the end of the rotating shaft 15 away from the motor 14 is fixedly connected to the input end of the reduction gear box 18, the output end of the reduction gear box 18 is fixedly connected to a rotating rod 19, the side wall of the rotating rod 19 is fixedly connected to a cam 20, the reduction gear box 18 is fixedly connected to the side wall of the vacuum pump 1, and the cam 20 is in contact with the outer wall of the gas tank 6.

[0028] The inner wall of the vertical pipe 3 is fixedly connected to the outer ring 7, the inner part of the outer ring 7 is sleeved with the inner ring 9, the inner wall of the outer ring 7 is movably connected to the sphere 8, the sphere 8 is movably connected to the outer wall of the inner ring 9, the inner wall of the inner ring 9 is fixedly connected to the rubber ring 10, the inner wall of the rubber ring 10 is sleeved with the gas tank 6, the rubber ring 10 improves the sealing degree and air tightness between the inner ring 9 and the gas tank 6, the top end face of the outer ring 7 is fixedly connected to the L-shaped ring 11, the top end face of the outer ring 7 is fixedly connected to the sealing ring 12, the bottom end face of the sealing ring 12 is abutted against the top end face of the inner ring 9, the top end face of the sealing ring 12 is fixedly connected to the spring 13, the end of the spring 13 away from the sealing ring 12 is fixedly connected to the inner top face of the L-shaped ring 11, the bottom of the sealing ring 12 is provided with a mounting groove, and the inner wall of the mounting groove is fixedly connected with grease 21.

The driving gear 16 rotates to drive the gear ring 17 and the gas tank 6 to rotate. When the gas tank 6 rotates, the water droplets have a certain rotational inertia.
