Description

Technical Field

[0001] The utility model mainly relates to the technical field of crude oil storage equipment, in particular to a crude oil tank bottom anti-deposition device. Background Art

[0002] The crude oil storage tank will form sediments over a certain period of time due to the moisture, impurities, centrifugal sediments, etc. of the crude oil itself. At present, the crude oil enters the tank through an oil pipeline to enter the tank bottom. Due to the limited flushing of the oil inlet pipe, there are many dead corners in the tank bottom area, resulting in a large amount of oil residue deposition, resulting in more and more oil residue at the bottom of the tank, affecting the storage of large tanks and the product quality. The tank needs to be cleaned regularly, which increases the production cost. Therefore, a crude oil tank bottom anti-deposition device is proposed. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a crude oil tank bottom anti-deposition device, which is implemented through the following technical solutions:

[0004] A crude oil tank bottom anti-deposition device comprises a tank body, wherein an oil inlet pipe is arranged on the top of the tank body, the lower end of the oil inlet pipe extends to the bottom of the inner wall of the tank body, and a rotating nozzle is fixedly installed on the lower end of the oil inlet pipe.

[0005] Furthermore, a plurality of evenly distributed oil outlet pipes are fixedly installed around the rotating spray head.

[0006] Furthermore, inclined tubes are fixedly installed at the ends of the oil outlet pipes, and the inclined tubes face the bottom of the tank body.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The device is provided with a rotating nozzle which can rotate 360 ​​degrees, so that the oil input is more uniform, the oil residue deposition is reduced, the frequency of manual tank cleaning is reduced, the production cost is reduced, and the crude oil storage effect is improved.

[0012] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0013] Embodiment: A crude oil tank bottom anti-deposition device

[0014] like Figure 1 - As shown in Figure 2, a crude oil tank bottom anti-deposition device, the specific structure of which includes:

[0015] A tank body 1 is used to store crude oil. An oil inlet pipe 2 is provided on the top of the tank body 1. The lower end of the oil inlet pipe 2 extends to the bottom of the inner wall of the tank body 1. A rotating nozzle 3 is fixedly installed on the lower end of the oil inlet pipe 2.

[0016] A plurality of evenly distributed oil outlet pipes 4 are fixedly installed around the rotating spray head 3 , and the oil outlet pipes 4 can rotate synchronously with the rotating spray head 3 .

[0017] The ends of the oil outlet pipes 4 are respectively fixedly mounted with inclined pipes 5, which face the bottom of the tank body 1. The design of the inclined pipes 5 allows the oil residue to be better washed away by the oil sprayed from the rotating nozzle, thereby reducing the frequency of manual tank cleaning, reducing production costs, and improving product quality.

[0018] Working principle:

[0019] When the device is in use, the crude oil enters the tank body 1 from top to bottom through the oil inlet pipe 2, and the 360-degree spraying of the rotating nozzle 3 is realized during the oil inlet process through the flow head of the crude oil delivery pump. The tank bottom is flushed during the oil inlet process, so that there is no dead angle at the tank bottom for oil inlet, and oil residue deposition is prevented.

[0020] The device rationally utilizes the energy of the oil pump when the crude oil enters the tank, and realizes the injection of the crude oil through the oil inlet pipe 2 and the rotating nozzle 3. In the later stage, it cooperates with the crude oil pipeline filtering device to solve the problems of oil residue deposition and poor crude oil quality, and has strong operability.

[0021] In the interpretation of the present invention, it should be noted that the terminology indicating the orientation is only for the convenience of description and understanding, and is not the only limitation on the installation position of the specific technical features, and does not exclude other possible installation methods.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
