Description

Technical Field

[0001] The invention relates to the technical field of fluid medium filling, in particular to a mobile storage tank sealing filling connector. Background Art

[0002] Due to the non-uniform size of tank truck openings and the loose seal between the crane pipe and the tank truck opening, the flat cap, conical cap, Maza type, bag type, magnetic type, and air bag type currently used cannot meet the requirements of closed loading. Moreover, compared with pneumatic sealing devices, manual sealing devices have higher labor intensity and are not easy and convenient to operate.

[0003] At the same time, the poor sealing effect of the top-loading crane pipe at the tanker mouth is a major problem that causes environmental pollution, endangers safety, and affects recovery efficiency. For volatile, flammable, explosive, corrosive or toxic media, closed loading not only reduces environmental pollution, but also reduces the occurrence of poisoning and fire and explosion incidents, and also improves the recovery efficiency of the oil and gas recovery system. Summary of the invention

[0004] The technical problem to be solved by the present invention is that: the sealing performance of the pipe connections at the tank truck ports is poor, the loading and unloading operations are not easy and convenient, and the labor intensity is high.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a mobile storage tank sealed filling connector, including a sleeve and a sealing cover, the bottom of the sealing cover is fixedly equipped with a vertical pipe through a flange, the upper surface of the sealing cover is fixedly equipped with a liquid phase interface fixedly connected to the vertical pipe, the upper surface of the sealing cover is fixedly equipped with a gas phase interface connected to the bottom of the sealing cover, the lower surface of the sealing cover is located inside the sleeve and is movably equipped with a large gear, a first small gear, a second small gear and a third small gear, an air motor for controlling the rotation of the first small gear is installed on the upper surface of the sealing cover, the inner side of the sleeve corresponds to the position of the second small gear and the third small gear is welded and fixed with an internal transmission frame, and the internal transmission frame is movably equipped with a pressure rod locking mechanism controlled by the second small gear and the third small gear.

[0006] The large gear is meshed with the first small gear, the second small gear and the third small gear for transmission at the same time.

[0007] The outer arc surfaces of the sleeve and the sealing cover are both sleeved with rubber sealing rings.

[0008] A strip-shaped longitudinal lifting opening with a built-in copper liner is provided on the outer side of the sealing cover at a position corresponding to the pressure rod locking mechanism.

[0009] The pressure rod locking mechanism comprises a longitudinal screw rod movably assembled in the internal transmission frame, an internal threaded slider threadedly sleeved on the threaded screw rod, and a pressure rod movably assembled on the outer side of the internal threaded slider.

[0010] An air control valve for controlling the air motor is welded and fixed on the outer side surface of the liquid phase interface.

[0011] A self-locking handle for controlling the locking state of the large gear is installed on the outer side surface of the sealing cover.

[0012] The large gear is movably assembled on the outer side of the vertical pipe connecting flange through the inner bearing.

[0013] The self-locking handle includes an internal control shaft that movably passes through the sealing cover, an external wrench fixed to the outer end of the internal control shaft, an internal extrusion block fixed to the side wall of the inner end of the internal control shaft, and a lateral locking block elastically installed on the inner side of the sealing cover.

[0014] The maximum turning angle of the pressure rod is 90°.

[0015] The beneficial effects of the present invention are:

[0016] (1) The sealing performance of the mobile storage tank sealing filling connector of the present invention is good. The locking force provided by the compression rod locking mechanism overcomes the factors that cause sealing failure. The locking force of the mechanism only acts between the sealing device and the tanker port, and has little effect on external factors such as the crane pipe and the tanker. Even under unfavorable conditions, a reliable seal can be produced;

[0017] (2) High degree of automation: The pneumatic method is used to realize automatic control of the locking and loosening actions. For fully automatic lifting pipes, the lifting pipes and sealing devices can be fully automatically controlled;

[0018] (3) The operation is simple. You only need to turn the pneumatic valve switch handle to complete the operation, which has low labor intensity and saves time and effort.

[0019] (4)Multi-layer sealing diameter, can adapt to different sizes of can mouths;

[0020] (5) The strip-shaped vertical lifting port uses a copper liner to prevent sparks when the pressure rod slides up and down in the slide groove;

[0021] (6) It is designed with a self-locking device. After the pneumatically driven pressure rod rises and clamps the tank mouth, the pressure rod mechanically self-locks to prevent the pressure rod from falling due to backflow and avoid locking failure;

[0022] (7) One pneumatic motor can drive multiple pressure rods. A reasonable number of pressure rods can be designed according to the different tank openings. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A self-locking handle 17 for controlling the locking state of the large gear 7 is installed on the outer side of the sealing cover 2 .

[0040] The large gear 7 is movably assembled on the outer side of the vertical pipe 4 connecting the flange 3 through the inner bearing.

[0041] The self-locking handle 17 includes an internal control shaft 171 that movably passes through the sealing cover 2, an external wrench 172 fixed to the outer end of the internal control shaft 171, an internal extrusion block 173 fixed to the side wall of the inner end of the internal control shaft 171, and a lateral locking block 174 elastically installed on the inner side of the sealing cover 2.

[0043] This application has smooth driving, reliable action, good sealing effect, high degree of automation, and is suitable for various working environments.

[0044] like Figure 6 and Figure 7 As shown, the action process is as follows: 1.

[0046] Action principle: 1. The pneumatic motor 11 can realize forward and reverse rotation by changing the paths of air intake and exhaust, which is suitable for the working conditions of locking and loosening the sealing device;

[0047] 2. The longitudinal screw 131 can convert the rotary motion into linear motion;

[0048] 3. Gear transmission realizes the transmission of torque and speed through the meshing of gears. It has high transmission efficiency and precision, compact structure and reliable operation.
