Description

Technical Field

[0001] This invention relates to the field of petrochemical equipment technology, specifically to a crude oil dehydration settling tank. Background Technology

[0002] Crude oil extracted from oil contains a certain proportion of water, which seriously affects its storage, transportation, and subsequent processing. Therefore, dehydration is necessary during the crude oil extraction stage. Common crude oil dehydration technologies include sedimentation dehydration, which separates free water from crude oil through a static process. Existing sedimentation dehydration uses horizontal sedimentation tanks for long-term static treatment of crude oil. However, this type of horizontal sedimentation tank causes the separated water to disperse at the bottom of the tank and not collect, resulting in some wastewater not being discharged from the bottom of the tank. Consequently, the discharge material at the end of the process still contains some wastewater. Therefore, it is necessary to improve and optimize the existing sedimentation equipment. Summary of the Invention

[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a crude oil dehydration settling tank. This tank has a two-stage lifting structure that effectively raises one end of the tank, allowing the settled wastewater at the bottom of the tank to collect and be easily discharged for treatment.

The support fins 16 are fixedly installed on the side wall of the base 1, and the upper side of the support fins 16 is fixedly installed on the outer side wall of the tank 2. The lower side of the support fins 16 is movably abutted against the surface of the foundation.

[0041] Lifting shaft seat 10, wherein the lifting shaft seat 10 is disposed at the lower front end of the base 1;

[0042] The lifting seat 11 is spun onto the lifting shaft seat 10 via a rotating shaft, and the rear end of the lifting seat 11 is connected to the front end of the load-bearing seat 4.

[0043] The lifting slide rail 12 is fixedly installed on the upper surface of the lifting seat 11, and the rear end of the lifting slide rail 12 is connected to the front end of the load-bearing slide rail 5.

[0044] The foot 13 is located below the rear end of the lifting seat 11 and is fixedly mounted on the foundation.

[0045] The lifting hydraulic rod 14 is screwed onto the upper surface of the pad 13 via a rotating shaft, and the output shaft of the lifting hydraulic rod 14 is screwed onto the rear end of the lower surface of the lifting seat 11 via a rotating shaft.

[0046] The force-bearing frame 15, wherein there are several force-bearing frames 15 and they are fixedly installed on the foundation, and the upper surface of the force-bearing frame 15 is movably abutted against the lower surface of the lifting seat 11;

[0047] End frame 17 is integrally formed and disposed at the front end of base 1, and end frame 17 is movably abutted against the upper surface of foundation.

[0048] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0049] When using this device, crude oil is dehydrated by settling through tank 2. Due to the large density difference between pure oil and water, the water that is dehydrated after a series of processing operations settles at the bottom of tank 2 for collection and discharge. Tank 2 is normally placed horizontally, so the dehydrated water is dispersed at the bottom of tank 2, which is not conducive to complete collection. Therefore, when collecting the water at the bottom of tank 2, the front end of tank 2 is raised upward so that the water at the bottom of tank 2 accumulates at the rear of tank 2 for complete collection.

[0050] During the installation of this device, the foundation pit is first excavated, which is divided into two sections, with the depth of the rear section being shallower than that of the front section. The width of the pit is equal to the width of the load-bearing seat 4 and the lifting seat 11. The rear section of the pit is used to install the load-bearing seat 4, and the front section is used to install the lifting seat 11. The tank body 2 is erected above the pit. The bottom of the rear section of the pit is constructed with an upward-raising slope. The load-bearing seat 4 is placed into the rear section of the pit, and the beam frame 7 is inserted into the side wall of the pit to complete the installation of the load-bearing seat 4. The installation and fixing are completed by fixing the pad 13 to the bottom of the front section of the pit and fixing the lifting shaft seat 10 to the inner wall of the front end of the pit, thereby completing the installation of the lifting seat 11. During daily use, the lifting seat 11 is lowered so that the rear end of the lifting seat 11 is connected with the front end of the load-bearing seat 4, the rear end of the lifting slide rail 12 is connected with the front end of the load-bearing slide rail 5, the load-bearing frame 6 slides to the rear of the load-bearing slide rail 5, the tank 2 is laid flat, and the base 1 is supported on the surface of the foundation through the support fin plate 16 and the end frame 17.

[0051] When the tank 2 is tilted to allow the water at the bottom of the tank 2 to collect, the self-locking motor first drives the stepper wheel 9 to move forward. The stepper wheel 9 then pushes the support frame 6 forward on the support rail 5. The support frame 6 slides forward along the upward-sloping support rail 5, so that the support frame 6 abuts against the base 1 via the support roller 8. As the support frame 6 rises, it pushes the base 1 upward, causing the base 1 to rotate with the connecting shaft to the support shaft seat 3 as support, thus lifting the front end of the base 1. This lifts the front end of the tank 2, causing the water at the bottom of the tank 2 to collect towards the rear end of the tank 2. The support frame 6 then slides from the support rail 5 to the lifting rail 12 and... After moving to the front end of the lifting slide rail 12, the rear end of the lifting seat 11 is pushed upward by the lifting hydraulic rod 14, so that the lifting seat 11 rotates with the connecting shaft with the lifting shaft seat 10 as support, so that the rear end of the lifting seat 11 is lifted, thereby lifting the rear end of the lifting slide rail 12 upward. Then, the load-bearing frame 6 slides backward on the lifting slide rail 12, so that the load-bearing frame 6 pushes the base 1 upward through the support roller. Then, the tank 2 is lifted for the first time by the load-bearing frame 6 sliding upward on the load-bearing slide rail 5 and the lifting slide rail 12. After the rear end of the lifting slide rail 12 is lifted, the tank 2 is lifted for the second time by the load-bearing frame 6 sliding backward on the lifting slide rail 12.

[0052] The technical advantages achieved by adopting the above technical solution are as follows:

[0053] 1. This device is equipped with a forward-tilting load-bearing slide rail 5, and a load-bearing frame 6 on the load-bearing slide rail 5. A rotatable base 1 is installed through the load-bearing shaft seat 3, and a tank 2 is installed through the base 1. This allows the front end of the tank 2 to be lifted, so that the sediment water accumulated at the bottom of the tank 2 can be collected and discharged from the rear end of the tank 2.

[0054] 2. This device sets up a lifting seat 11 to connect with a load-bearing seat 4, and sets up a lifting slide rail 12 on the lifting seat 11 to connect with a load-bearing slide rail 5. After the load-bearing frame 6 moves forward to push and lift the tank 2, the rear end of the lifting seat 11 is lifted and the load-bearing frame 6 is moved backward to achieve a secondary lifting of the tank 2.

[0055] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
