Description

Technical Field

[0001] The utility model relates to the technical field of hydration treatment, in particular to a hydration tank with adjustable flow rate. Background Art

[0002] A hydration tank, also known as a hydration pot, is a device used for intermittent hydration of oils and fats. It is primarily used for hydration during oil processing. Hydration tanks play a vital role in oil refining. Through a specific process flow, they effectively hydrate oils and fats, ensuring their quality and stability.

[0003] During the oil hydration process, a certain amount of hot water or an aqueous electrolyte solution, such as a dilute alkali, salt, or phosphoric acid, must be added to the hydration tank under certain conditions and mixed with the crude oil to cause the colloidal impurities in the crude oil to condense and settle. The addition of the aqueous electrolyte solution must be proportionally adjusted to the volume of the crude oil. Existing feed pipes on hydration tanks can only control the opening and closing of the medium flow, not the flow rate. Therefore, it is impossible to adaptively add the aqueous electrolyte solution according to the volume of the crude oil, which to some extent affects production efficiency. Therefore, a hydration tank with adjustable flow rate is urgently needed to solve this problem. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0005] Specifically, the technical problem to be solved by the present invention is to provide a hydration tank with adjustable flow rate to solve the technical problem that the feed pipe on the existing hydration tank can only be used to control the opening and closing of the medium flow, but cannot control the flow rate. Therefore, it is impossible to adaptively add electrolyte aqueous solution according to the capacity of crude oil, which affects production efficiency to a certain extent.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A hydration tank with adjustable flow rate, comprising a hydration tank body and a crude oil feed pipe fixedly mounted on the top of the hydration tank body, wherein a solution feed pipe is fixedly connected to one side of the crude oil feed pipe, a material control valve is mounted on one end of the solution feed pipe, and a drive mechanism for driving the material control valve to rotate is mounted within the crude oil feed pipe;

[0008] The driving mechanism includes a liquid storage tank, a plurality of through holes are opened at the bottom of the liquid storage tank, a buoyancy tank is provided in the liquid storage tank, a rotating rod is provided on the buoyancy tank for transmission, and the material control valve includes a limit frame fixedly connected to the solution feed pipe, a valve plate is abutted on one side of the limit frame, and the valve plate is rotatably connected to the solution feed pipe and is transmission-connected to the rotating rod.

[0009] As an improved technical solution, a fixing frame is fixedly connected to the liquid storage tank, a lifting rod is slidably connected inside the fixing frame, one end of the lifting rod is fixedly connected to the buoyancy chamber, and the other end is in sliding contact with the rotating rod.

[0010] As an improved technical solution, the rotating rod is L-shaped and is rotatably connected to the crude oil feed pipe. One end of the rotating rod is hinged to the valve plate through a connecting rod.

[0011] As an improved technical solution, one side of the valve plate is elastically connected to the solution feed pipe via a spring.

[0012] As an improved technical solution, a regulating switch valve is installed on the solution feed pipe.

[0013] As an improved technical solution, two guide plates are symmetrically provided on the lower side of the liquid storage tank, and the guide plates are connected and fixed to the inner wall of the crude oil feed pipe.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] 1. The utility model drives the buoyancy chamber to rise when crude oil accumulates in the liquid storage tank, causing the rotating rod to rotate and the valve plate to automatically rotate and open. When the crude oil feed pipe discharges crude oil into the hydration tank, the solution feed pipe can automatically discharge solution into the hydration tank, realizing automatic flow control. The flow of the solution can be further controlled by adjusting the switch valve, simplifying the production process and improving production efficiency.

[0016] 2. The utility model can preliminarily mix the solution and crude oil when passing through the guide plate, and then mix them again after falling into the hydration tank, thereby reducing the mixing time of the solution and crude oil and further improving production efficiency.

[0028] like Figure 1-4As shown together, this embodiment provides a hydration tank with adjustable flow rate, which includes a hydration tank body 1 and a crude oil feed pipe 2 fixedly installed on the top of the hydration tank body 1. A solution feed pipe 3 is fixedly connected to one side of the crude oil feed pipe 2, and a control valve 5 is installed at one end of the solution feed pipe 3. A driving mechanism 4 for driving the control valve 5 to rotate is installed in the crude oil feed pipe 2.

[0029] The driving mechanism 4 includes a liquid storage tank 401, and a plurality of through holes are opened at the bottom of the liquid storage tank 401. A buoyancy tank 404 is provided in the liquid storage tank 401. The buoyancy tank 404 is equipped with a rotating rod 405 for transmission. The material control valve 5 includes a limit frame 501 fixedly connected to the solution feed pipe 3. One side of the limit frame 501 is abutted with a valve plate 502. The valve plate 502 is rotatably connected to the solution feed pipe 3 and is transmission-connected to the rotating rod 405.

[0030] In the above technical solution, as crude oil flows into the hydration tank body 1 through the crude oil feed pipe 2, the liquid storage tank 401 is first filled. The buoyancy chamber 404 rises with the liquid and drives the rotating rod 405 to rotate. The rotating rod 405 can drive the valve plate 502 to rotate and disengage from the limit frame 501. At this time, the solution feed pipe 3 is opened to discharge the solution into the crude oil feed pipe 2, realizing automatic opening and closing of the medium flow.

[0031] The sum of the flow rates of the through holes of the liquid storage tank 401 is less than the flow rate of the crude oil feed pipe 2, so that when the crude oil is transported into the hydration tank body 1, the liquid storage tank 401 can be quickly filled, driving the buoyancy chamber 404 to rise. When the crude oil transportation stops, the crude oil in the liquid storage tank 401 is discharged through the through holes, and the buoyancy chamber 404 descends. At this time, the valve plate 502 can automatically close.

[0032] A partition is fixedly connected to the upper side of the crude oil feed pipe 2 near the solution feed pipe 3 . The partition is used to allow the crude oil to quickly enter the liquid storage tank 401 and at the same time block the liquid outlet of the solution feed pipe 3 .

[0033] A fixing frame 402 is fixedly connected to the liquid storage tank 401 , and a lifting rod 403 is slidably connected inside the fixing frame 402 . One end of the lifting rod 403 is fixedly connected to the buoyancy chamber 404 , and the other end is in sliding contact with the rotating rod 405 .

[0034] In the above technical solution, the fixing frame 402 vertically limits the lifting rod 403 so that when the buoyancy chamber 404 rises, the lifting rod 403 moves synchronously, thereby driving the rotating rod 405 to rotate.

[0035] The fixing frame 402 is provided in a cone-shaped structure to guide the crude oil and prevent the falling crude oil from directly impacting the buoyancy chamber 404, thereby keeping the buoyancy chamber 404 stable.

[0036] The rotating rod 405 is L-shaped and is rotatably connected to the crude oil feed pipe 2 . One end of the rotating rod 405 is hinged to the valve plate 502 via a connecting rod 406 .

[0037] In the above technical solution, the lifting rod 403 rises and comes into sliding contact with the rotating rod 405 , and the rotating rod 405 rotates so that one end thereof drives the valve plate 502 to rotate through the connecting rod 406 .

[0038] The distance between the rotation axis of the rotating rod 405 and the lifting rod 403 is greater than the distance between the rotation axis of the rotating rod 405 and the connecting rod 406, so that the lifting rod 403 drives the valve plate 502 to rotate through the rotating rod 405, which is a labor-saving movement.

[0039] One side of the valve plate 502 is elastically connected to the solution feeding pipe 3 via a spring 503 .

[0040] In the above technical solution, when the rotating rod 405 stops applying pressure to the valve plate 502 , the spring 503 returns to its original position and drives the valve plate 502 to abut against the limit frame 501 , thereby closing the channel of the solution feeding pipe 3 .

[0041] The forward projection area of ​​the valve plate 502 is smaller than the projection area of ​​the limit frame 501, so that when the valve plate 502 rotates, a gap is generated between the valve plate 502 and the limit frame 501, which facilitates the flow of solution. Rubber sheets are provided on the opposite sides of the limit frame 501 and the valve plate 502 to improve sealing.

[0042] The solution feed pipe 3 is provided with a regulating switch valve 6 , and the regulating switch valve 6 can be rotated to adjust the flow rate of the solution in the solution feed pipe 3 , thereby controlling the mixing ratio with the crude oil.

[0043] Two guide plates 7 are symmetrically provided on the lower side of the liquid storage tank 401 . The guide plates 7 are fixedly connected to the inner wall of the crude oil feed pipe 2 . The guide plates 7 can perform preliminary mixing of the crude oil and the solution, thereby shortening the subsequent mixing time.

[0044] During use, when crude oil flows into the hydration tank body 1 through the crude oil feed pipe 2, the liquid storage tank 401 will be filled first. The buoyancy chamber 404 rises with the liquid, causing the lifting rod 403 to drive the rotating rod 405 to rotate. The rotating rod 405 drives the valve plate 502 to rotate and disengage from the limit frame 501 through the connecting rod 406. At this time, the solution feed pipe 3 is opened to discharge the solution into the crude oil feed pipe 2. When the crude oil stops being transported, the crude oil in the liquid storage tank 401 is discharged through the through hole, the buoyancy chamber 404 descends, the rotating rod 405 rotates in the opposite direction, and the spring 503 resets, causing the valve plate 502 to rotate to fit the limit frame 501, and the channel of the solution feed pipe 3 is automatically closed.

[0045] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
