Description

Technical Field

[0001] This invention relates to the field of vacuum equipment technology, specifically to a vacuum equipment for the anti-corrosion treatment of large-scale petrochemical raw material storage. Background Technology

[0002] Petroleum refers to a mixture of gaseous, liquid, and solid hydrocarbons that occur naturally. Petroleum is further classified into crude oil, natural gas, liquefied natural gas, and natural tar, but conventionally, "petroleum" is still used as the definition of "crude oil."

[0003] Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." It is found in some areas of the upper crust and is mainly composed of a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. It is one of the primary targets of geological exploration.

[0004] The existing vacuum pumping devices have the following problems during use:

[0005] Existing petrochemical raw material storage methods involve injecting petroleum materials while simultaneously creating a vacuum to remove oxidizing gases from the storage tank. However, this results in prolonged contact between the oxidizing gases and the petroleum raw materials, increasing the likelihood of corrosion and economic damage. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a vacuuming device for corrosion prevention in large-scale petrochemical raw material storage. This device automatically injects crude petroleum solution after the vacuuming equipment has been operating for a certain period. This pre-vacuuming followed by injection reduces the probability of contact between the crude petroleum solution and air, thus improving the corrosion prevention effect. It solves the problem that existing petrochemical raw material storage methods involve simultaneous injection and vacuuming to remove oxidizing gases from the storage tank. However, this results in prolonged contact between the oxidizing gases and the petroleum raw materials, increasing the probability of corrosion and economic losses. To achieve the above objectives, this invention employs the following technical solution:

[0007] A vacuuming device for corrosion protection of large-scale petrochemical raw material storage includes a storage tank, an anti-collision ring welded to the outer surface of the storage tank, a control device welded to the front of the storage tank, an inlet pipe welded to the bottom of the storage tank, an outlet pipe welded to the bottom of the storage tank, a vacuuming device bolted to the top of the storage tank, and a control switch welded to the top of the vacuuming device.

[0008] The control switch has several wires inside, and a movable block is movably installed inside the control switch.

[0009] Each of the wires is electrically connected to a connecting block on one of its closest sides;

[0010] A blocking block is welded to the bottom of the movable block, an elastic rod is welded to the top of the movable block, and a conductor block is welded to the top of the elastic rod.

[0011] Preferably, the bottom of the storage tank is welded with several bases, which provide stable support for the storage tank.

[0012] Preferably, the control device has a control panel electrically connected to its front side, allowing operators to control the operation of equipment inside the storage tank.

[0013] Preferably, the inlet pipe is internally connected to a rotating shaft, a handwheel is welded to the top of the rotating shaft, and a drive motor is welded to the bottom of the rotating shaft, so that the operator can manually close the rotating shaft by using the handwheel.

[0014] Preferably, a valve is welded to the outer surface of the rotating shaft, and the valve is shaped to match the diameter of the inlet pipe. The opening and closing of the inlet pipe can be controlled by rotating the valve on the rotating shaft.

[0015] Preferably, the inlet pipe and the outlet pipe have the same structure.

[0016] Preferably, the vacuum equipment has an air inlet welded to the bottom and an exhaust pipe welded to the top. When the operator needs to inject a certain amount of crude petroleum liquid into the storage tank, the vacuum equipment is first started through the control panel of the control device, and the vacuum equipment begins to work.

[0017] The beneficial effects of this invention are as follows:

[0018] Compared with the prior art, the present invention provides a vacuum device for large-scale petrochemical raw material storage and corrosion prevention treatment, which has the following beneficial effects:

[0019] This large-scale petrochemical raw material storage and corrosion protection vacuum device, through the coordinated operation of the storage tank, anti-collision ring, control device, inlet pipe, outlet pipe, vacuum equipment, and control switch, allows for the injection of a certain amount of petroleum crude liquid into the storage tank. First, the vacuum equipment is activated via the control panel. The vacuum equipment draws in gas from inside the storage tank through the inlet and exhausts it through the outlet pipe, creating an upward impact force. This gas impacts the blocking block, causing it to move upward and overcome the elastic force of the elastic rod. Consequently, the conductor block moves upward with the blocking block. When the conductor block has moved a certain distance, it contacts the connecting blocks on both sides, connecting them. This activates the drive motor inside the inlet pipe, which rotates the shaft. The shaft then opens the control valve, allowing the petroleum crude liquid to be delivered into the storage tank. This achieves automatic injection of petroleum crude liquid after the vacuum equipment has been operating for a certain period, effectively reducing the probability of contact between the petroleum crude liquid and air, thus improving the corrosion protection effect.

Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Please see Figures 1-5 A vacuum device for corrosion protection of large-scale petrochemical raw material storage includes a storage tank 1. Several bases 11 are welded to the bottom of the storage tank 1, providing stable support and further improving its service life. Anti-collision rings 2 are welded to the outer surface of the storage tank 1. A control device 3 is welded to the front of the storage tank 1, and a control panel 31 is electrically connected to the front of the control device 3. Operators can control the operation of the equipment inside the storage tank 1 through the control panel 31, reducing the complexity of equipment operation.

[0030] The bottom of storage tank 1 is welded with an inlet pipe 4. The inlet pipe 4 is internally connected to a rotating shaft 41. The top of the rotating shaft 41 is welded with a handwheel 42, and the bottom of the rotating shaft 41 is welded with a drive motor 43. The operator can manually close the rotating shaft 41 by using the handwheel 42, or remotely control the drive motor 43 to rotate the rotating shaft 41 to achieve the effect of remote closure. The outer surface of the rotating shaft 41 is welded with a valve 411, and the valve 411 is compatible with the diameter and shape of the inlet pipe 4. The opening and closing of the inlet pipe 4 can be controlled by rotating the valve 411 on the rotating shaft 41. The bottom of storage tank 1 is welded with an outlet pipe 5. The inlet pipe 4 and the outlet pipe 5 have the same structure. The top of storage tank 1 is bolted with a vacuum device 6. The bottom of the vacuum device 6 is welded with an air inlet 61, and the top of the vacuum device 6 is welded with an exhaust pipe 62.

[0031] When the staff needs to inject a certain amount of crude petroleum liquid into the storage tank 1, they first start the vacuum equipment 6 through the control panel 31 of the control device 3. The vacuum equipment 6 starts to work, sucking in the gas inside the storage tank 1 through the air inlet 61 and expelling it through the exhaust pipe 62, thus forming an upward impact force. The top of the vacuum equipment 6 is welded with a control switch 7. Several wires 71 are installed inside the control switch 7. A movable block 72 is installed inside the control switch 7. The side of the wires 71 is electrically connected to a connecting block 711. A blocking block 721 is welded to the bottom of the movable block 72. An elastic rod 722 is welded to the top of the movable block 72. A conductor block 723 is welded to the top of the elastic rod 722.

[0032] Working principle: When the operator needs to inject a certain amount of crude petroleum liquid into the storage tank 1, the vacuum equipment 6 is first started through the control panel 31 of the control device 3. The vacuum equipment 6 starts working, sucking in the gas inside the storage tank 1 through the air inlet 61 and expelling it through the exhaust pipe 62, thus forming an upward impact force. The gas impacts the blocking block 721, which moves upward and overcomes the elastic force of the elastic rod 722. Consequently, the conductor block 723 moves upward with the blocking block 721. When the conductor block 723 moves upward a certain distance, it contacts the connecting blocks 711 on the left and right sides, making the connecting blocks 711 connected. This controls the drive motor 43 inside the liquid inlet pipe 4 to drive the rotating shaft 41 to rotate. The rotating shaft 41 controls the valve 411 to open, thus allowing the crude petroleum liquid to be delivered into the storage tank 1.

[0033] In summary, this large-scale petrochemical raw material storage and corrosion protection vacuum device, through the coordinated operation of storage tank 1, anti-collision ring 2, control device 3, inlet pipe 4, outlet pipe 5, vacuum equipment 6, and control switch 7, allows for the injection of a certain amount of petroleum raw material into storage tank 1. First, the vacuum equipment 6 is activated via the control panel 31 of the control device 3. The vacuum equipment 6 then draws in gas from inside storage tank 1 through inlet 61 and discharges it through exhaust pipe 62, creating an upward impact force. The gas impacts the blockage block 721, causing it to move upwards and overcome the blockage. The elastic force of the elastic rod 722 causes the conductor block 723 to move upward along with the blocking block 721. When the conductor block 723 moves upward a certain distance, it contacts the connecting blocks 711 on the left and right sides, making the connecting blocks 711 on the left and right sides conductive. This controls the drive motor 43 inside the liquid inlet pipe 4 to drive the rotating shaft 41 to rotate. The rotating shaft 41 controls the valve 411 to open, thus allowing the petroleum raw liquid to be transported into the storage tank 1. This achieves the effect of automatically injecting petroleum raw liquid after the vacuuming equipment 6 has been working for a certain period of time. This achieves the effect of vacuuming first and then injecting liquid, reducing the probability of petroleum raw liquid coming into contact with air and improving the anti-corrosion effect.
