Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of petroleum storage tank cleaning, specifically, a petroleum storage device convenient to clean. BACKGROUND

[0002] Petroleum refers to gaseous, liquid and solid hydrocarbon mixtures with natural occurrence. Petroleum is divided into crude oil, natural gas, natural gas liquid and natural tar, etc. forms, and petroleum storage devices are needed in petroleum production to store petroleum.

[0003] At present, vertical storage tanks are generally used to store petroleum. The vertical storage tank includes a manhole and a discharge port. After the petroleum storage tank is used for a period of time, impurities in the crude oil will deposit on the tank bottom and tank wall, reducing the effective capacity of the oil storage tank. Therefore, the petroleum storage tank needs to be regularly inspected, repaired and cleaned of sludge in the tank. The current domestic traditional oil tank cleaning method mainly uses manual labor, and the steps are as follows:

[0004] (1) First, the crude oil in the storage tank is drained, and then a worker enters the inside of the storage tank from the manhole;

[0005] (2) After entering the inside of the petroleum storage tank, the surface sludge is manually removed with an explosion-proof shovel or a scraper, and the hardened sediment layer is washed with a water gun while constantly adjusting the position;

[0006] (3) After cleaning, the worker climbs out of the manhole;

[0007] The above steps have high labor intensity and safety hazards in the cleaning process of the petroleum storage tank. In summary, there is currently a lack of an automatic and convenient petroleum vertical storage tank for cleaning internal impurities. UTILITY MODEL CONTENTS

Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. The present application is further described in conjunction with the drawings and embodiments:

[0038] As shown in Figure 1 and Figure 2 , a kind of oil storage device convenient to clean, including vertical storage tank 1, vertical storage tank 1 including manhole 2 and discharge port 3, further including multistage telescopic piece 4, mounting plate 5, conveying pipe 6, cleaning box 7, spray head 8, gear transmission assembly 9, swivel joint 10, high-pressure pump 11 and slurry pump 12,

[0039] Multistage telescopic piece 4 is symmetrically fixed on vertical storage tank 1 and multistage telescopic piece 4 is connected with mounting plate 5;

[0040] Conveying pipe 6 is rotatably connected with mounting plate 5 and one end of conveying pipe 6 is connected with internally hollow cleaning box 7;

[0041] Spray head 8 is arranged at the bottom and side of cleaning box 7 respectively;

[0042] Gear transmission assembly 9 is fixed on mounting plate 5, and gear transmission assembly 9 is connected with conveying pipe 6;

[0043] Swivel joint 10 is communicated with the other end of conveying pipe 6, and swivel joint 10 is connected with high-pressure pump 11;

[0044] Slurry pump 12 is connected with discharge port 3 through flange.

[0045] Further refinement of the embodiment scheme of the utility model, vertical storage tank 1 is symmetrically fixed with multistage telescopic rod connected with mounting plate 5, and multistage telescopic rod is not shown in the figure.

[0046] It should be noted that multistage telescopic piece 4, gear transmission assembly 9, high-pressure pump 11 and slurry pump 12 are electrically connected with controller, and control box is not shown in the figure.

[0047] The working process of the utility model:

[0048] When the inside of vertical oil storage tank 1 needs to be cleaned and the crude oil is exhausted, immediately control multistage telescopic piece 4 to move and drive cleaning box 7 to enter the inside of vertical storage tank 1 from manhole 2 (not initially enter), immediately high-pressure pump 11 works to pressurize water source into conveying pipe 6 and finally synchronously spray from multiple spray heads 8, side spray head 8 can clean the side wall of vertical storage tank 1, bottom spray head 8 can clean the bottom of vertical storage tank 1, at the same time, control gear transmission assembly 9 to work through controller to drive conveying pipe 6 to rotate at high speed with cleaning box 7, to clean the area more comprehensively, immediately the impurities and oil stains washed down by high-speed water jet can flow to the bottom of vertical storage tank 1, immediately control slurry pump 12 to work through controller to pump waste liquid and oil stains to outside;

[0049] After the jet cleaning of the inner wall of the vertical oil storage tank 1 is completed, the gear transmission assembly 9 stops working, but water continues to flow to cooperate with the slurry pump 12 to improve the discharge effect of waste liquid and minimize the amount of waste liquid residue. Subsequently, manual assistance is used to completely drain the waste liquid.

[0050] Compared with existing technologies, this device makes the cleaning process inside the vertical oil storage tank 1 more convenient and intelligent. It effectively washes away impurities and oil stains through high-speed water jets, and the cleaning area is comprehensive. After cleaning, the waste liquid is pumped and transferred to the outside by slurry pump 12. This greatly reduces the labor intensity and safety hazards of manual operation. The vertical oil storage tank 1 has a self-cleaning function, resulting in better performance.

[0051] In some embodiments, such as Figure 3 and Figure 4 As shown, splash guards are fitted on the manhole 2 at intervals from the delivery pipe 6;

[0052] Specifically, the splash-proof assembly includes two splash plates 13, a magnet 14, and a semi-circular hole 15. The splash plate 13 is embedded with a magnet 14 that is flush with its surface and has a semi-circular hole 15. The magnet 14 is magnetically attracted to the area where the manhole 2 of the vertical storage tank 1 is located. The diameter of the circular hole formed after the two splash plates 13 are connected is larger than the diameter of the conveying pipe 6.

[0053] A further optimization of the above embodiment is that the splash guard 13 is provided with a handle, which is not shown in the figure; in this embodiment, the splash guard assembly allows the cleaning box 7 to be assembled after entering the vertical storage tank 1 through the manhole 2 and before the cleaning process begins. After assembly, the delivery pipe 6 is located within the circular hole formed by the two semi-circular holes 15 and does not contact each other (as per the instruction manual). Figure 4 As shown), this does not affect the subsequent rotation of the conveying pipe 6. At the same time, the manhole 2 of the vertical storage tank 1 is made of carbon steel, which can be attracted to the magnet 14. Thus, the splash guard 13 is magnetically confined to the area where the manhole 2 of the vertical storage tank 1 is located to block its entrance and greatly reduce the amount of waste liquid splashing outward during the cleaning process. When the internal cleaning of the vertical storage tank 1 is completed and the cleaning box 7 needs to be moved to the outside of the vertical storage tank 1, the splash guard 13 can be separated from the vertical storage tank 1 by applying force to the handle.

[0054] In other embodiments, such as Figure 5As shown, the input end of the high-pressure pump 11 is communicated with the output pipeline of the three-way pipe 16, the remaining two input pipelines of the three-way pipe 16 are respectively communicated with a hot water tank and a chemical reagent tank, and the remaining two input pipelines of the three-way pipe 16 are respectively provided with independently controlled electromagnetic valves 17; through the high-pressure pump 11, the embodiment can not only deliver water sources, but also deliver chemical reagents to target decompose viscous / chemical combined impurities in the vertical oil storage tank 1, in addition, heating on the basis of high jet flow can further improve the cleaning effect and reduce the residue of waxy substances, hot water and chemical reagents can be sequentially introduced according to needs for comprehensive cleaning, and thus the cleaning effect is better, and the hot water tank and the chemical reagent tank are not shown in the figure.

[0055] In other embodiments, the inner side of the splash plate 13 is provided with an activated carbon adsorption layer, which is not shown in the figure;

[0056] Further optimization of the above embodiment scheme, the vertical storage tank 1 is provided with a suction device on one side of the manhole 2 and the suction device is communicated with a purification device; the embodiment is not shown in the figure; through the activated carbon adsorption layer, the splash plate 13 can have the adsorption function of volatile gas on the basis of the splash-proof function, at the same time, the suction device and the purification device are further matched to reduce the amount of harmful gas volatilized into the surrounding environment, and thus the safety in the cleaning process is improved, and the suction device and the purification device both belong to the prior art and are not improved, and a gas pump matched with a purifier can be specifically used.
