Description

Technical Field

[0001] This utility model belongs to the field of crude oil storage technology, specifically relating to a crude oil storage tank for petrochemical applications. Background Technology

[0002] Petrochemicals are an important part of the chemical industry and play a vital role in the development of the national economy. Crude oil obtained from oil extraction needs to be stored, which requires crude oil storage containers.

[0003] As disclosed in the publication (announcement) number CN221679446U, this utility model discloses a crude oil storage tank for oil drilling, including a tank body with a chamber inside. A sleeve shaft is rotatably connected to the top of the chamber, and multiple frames are fixedly connected to the bottom of the sleeve shaft. Multiple stirring blades are fixedly connected to the frames, and a ring is fixedly connected to the bottom of each frame. The ring is rotatably connected to a rotating shaft, which is rotatably connected to the sleeve shaft. Multiple stirring blades are fixedly connected to the side of the rotating shaft. Two lead screws are rotatably connected inside the chamber, and the two lead screws are threadedly connected to scrapers. The scrapers movably contact the inner side wall of the chamber. A square cavity is opened at the top of the tank. Through the cooperation of various components, this utility model allows the scrapers to scrape the crude oil off the side wall of the chamber when it is discharged, preventing the crude oil from sticking, avoiding resource waste, and ensuring the capacity of the tank. Furthermore, when storing crude oil, the stirring blades rotate in opposite directions, which can better agitate the crude oil, prevent it from solidifying, and effectively reduce its viscosity.

[0004] Analysis revealed that the current scraping method involves vertical scraping, which can cause the crude oil to accumulate at the highest point and eventually adhere to the inner wall of the container. Furthermore, because the method involves agitation, some crude oil residue remains on the agitator blades, which can deteriorate over time and require cleaning, a process that is inconvenient. Therefore, the proposed solution needs optimization and improvement to address these issues. Utility Model Content

A motor is fixedly installed on one side of the storage tank body. The storage tank body has an internal cavity with a bevel gear rotatably connected within it. A bevel gear 2 is fixedly installed at one end of the motor's output end extending into the cavity, and the bevel gears 1 and 2 mesh with each other. A connecting rod is fixedly installed on the bevel gear 1. A rotating block is rotatably connected to the inner bottom surface of the storage tank body, and the connecting rod is fixedly connected to the rotating block. The rotating block has a protrusion, and a stirring shaft is inserted into the rotating block through the protrusion.

[0023] A crude oil storage tank for petrochemical use includes a storage tank body 1, a convenient moving mechanism on the outside of the storage tank body 1, and a detachable cleaning mechanism on the storage tank body 1.

[0024] The detachable cleaning mechanism includes a cover plate 2 hinged to the storage tank body 1, an oil supply pipe 3 connected to the cover plate 2, a motor 4 fixedly installed on one side of the storage tank body 1, a cavity inside the storage tank body 1, a bevel gear 5 rotatably connected inside the cavity, a bevel gear 6 fixedly installed at one end of the output end of the motor 4 extending into the cavity, bevel gear 5 and bevel gear 6 meshing with each other, a connecting rod 7 fixedly installed on bevel gear 5, a rotating block 8 rotatably connected to the inner bottom surface of the storage tank body 1, the connecting rod 7 fixedly connected to the rotating block 8, a protrusion 9 on the rotating block 8, a stirring shaft 10 inserted into the rotating block 8 through the protrusion 9, a plurality of stirring blades 11 and a connecting shaft 12 evenly fixedly installed on the stirring shaft 10, a threaded scraper 13 fixedly installed at the other end of the connecting shaft 12, the threaded scraper 13 slidably connected to the inner wall of the storage tank body 1, the cover plate 2 rotatably connected to the stirring shaft 10, and an oil drain pipe 14 connected to the storage tank body 1.

[0025] As described above, the control motor 4 operates, driving bevel gear 5 and bevel gear 6 to rotate. Under the action of the connecting rod 7, the rotating block 8 rotates, driving the stirring shaft 10 to rotate, so that the stirring blade 11 and the threaded scraper 13 respectively stir and scrape the crude oil on the inner wall of the storage tank body 1. When it is necessary to replace and clean, the cover plate 2 is opened, and the stirring shaft 10 can be pulled out directly to achieve quick separation. After cleaning, the stirring shaft 10 is aligned with the corresponding protrusion 9 so that the stirring shaft 10 fits with the protrusion 9. Then the cover plate 2 is closed. The pressure of the cover plate 2 ensures that the stirring shaft 10 has a stable working environment.

[0026] As a technical optimization of this utility model, the convenient moving mechanism includes a support column 15 and a pulley 16 symmetrically arranged on the lower side of the storage tank body 1. The lower side of the support column 15 and the pulley 16 is horizontal. A connecting block 17 is symmetrically fixedly installed on the side of the storage tank body 1 corresponding to the pulley 16. A push rod 18 is inserted and connected to the connecting block 17.

[0027] As can be seen from the above description, when the movement of the storage tank body 1 is not controlled, the storage tank body 1 can be laid flat. The friction of the support column 15 makes the storage tank body 1 stable on the ground. When it is necessary to move the storage tank body 1, the push rod 18 is inserted into the corresponding connecting block 17, so that one side of the support column 15 lifts off the ground. The lever principle can be used to drive the storage tank body 1 to move through the pulley 16. The push rod 18 can be removed when the storage tank body 1 does not need to be moved, reducing the space occupied.

[0028] As a technical optimization of this utility model, a buckle 19 is provided between the storage tank body 1 and the cover plate 2;

[0029] As can be seen from the above description, the design of the snap-fit ​​19 can effectively and quickly realize the opening and closing between the cover plate 2 and the storage tank body 1.

[0030] As a technical optimization of this utility model, a rubber ring 20 is fixedly installed on the cover plate 2 corresponding to the storage tank body 1;

[0031] As can be seen from the above description, the rubber ring 20 can improve the sealing between the storage tank body 1 and the cover plate 2.

[0032] As a technical optimization of this utility model, protrusion 9 is a regular hexagonal protrusion;

[0033] As can be seen from the above description, the hexagonal protrusion 9 is more convenient to manufacture and has higher practicality, and can effectively fix the rotating block and the stirring shaft.

[0034] The working process of this utility model is as follows:

[0035] Workers input crude oil into the storage tank body through the oil pipeline and discharge oil through the oil drain pipe 14. Under normal circumstances, the motor 4 works, driving the bevel gear 5 and bevel gear 6 to rotate. Under the action of the connecting rod 7, the rotating block 8 rotates, driving the stirring shaft 10 to rotate, so that the stirring blade 11 and the threaded scraper 13 stir and scrape the crude oil on the inner wall of the storage tank body 1 respectively. When it is necessary to replace and clean, the cover plate 2 is opened, and the stirring shaft 10 can be pulled out directly to achieve quick separation. After cleaning, the stirring shaft 10 is aligned with the corresponding protrusion 9, so that the stirring shaft 10 fits with the protrusion 9. Then the cover plate 2 is closed. The pressure of the cover plate 2 makes the stirring shaft 10 have a stable working environment. When it is necessary to move the entire storage tank body 1, the push rod 18 is inserted into the connecting block 17, and one end of the support column 15 is tilted up, so that the pulley 16 contacts the ground alone, which can easily achieve the movement control of the storage tank body 1.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this.
