Description

Technical Field

[0001] This utility model relates to the technical field of dehydration and upgrading devices, and in particular to a shale oil dehydration and upgrading device. Background Technology

[0002] Shale crude oil is synthetic crude oil produced from oil shale through processing. It is composed of a variety of organic compounds and is characterized by high sulfur content and easy corrosion of equipment. In the early days, this substance was mainly used directly as fuel, but later it developed into an important raw material for the petroleum, chemical and other industries. As an important unconventional petroleum resource, the dehydration and upgrading of shale oil is a key step in the processing. It is used to reduce the water content of crude oil to meet refining standards, reduce equipment corrosion and energy consumption, and improve oil quality to enhance market competitiveness.

However, existing static mixers mostly mix demulsifiers and crude oil directly through the mixer. But the mixing of demulsifiers with crude oil requires adjustment based on the water content of the crude oil, thus necessitating improvement. Utility Model Content

[0056] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a shale oil dehydration and upgrading device.

[0057] A shale oil dehydration and upgrading device includes a support pipe 1 and a support ring 2, with the support ring 2 fixedly connected to the support pipe 1; it also includes: an oil delivery pipe 3, disposed on the support pipe 1 and fixedly connected to the support pipe 1; a feed pipe 4, disposed on the oil delivery pipe 3 and fixedly connected to the oil delivery pipe 3; multiple spiral blades 5, evenly arranged inside the support pipe 1 and fixedly connected to the support pipe 1; an opening and closing mechanism, disposed on the oil delivery pipe 3, used to control the amount of demulsifier in the feed pipe 4; an opening and closing rod 6, disposed on the feed pipe 4 and rotatably connected to the feed pipe 4; an opening and closing plate 7, disposed inside the feed pipe 4 and fixedly connected to the opening and closing rod 6; and a stirring mechanism, disposed on the oil delivery pipe 3.

[0058] Reference Figure 5 In a preferred embodiment, the opening and closing mechanism includes: an opening and closing block 8, which is disposed on the oil supply pipe 3 and fixedly connected to the oil supply pipe 3; an opening and closing frame 9, which is disposed on the opening and closing block 8 and fixedly connected to the opening and closing block 8; an opening and closing motor 10, which is fixedly connected to the opening and closing frame 9; an opening and closing shaft 11, which is fixedly connected to the output end of the opening and closing motor 10; a rotating component, which is disposed on the opening and closing shaft 11; a first rotating gear 12, which is disposed on the opening and closing shaft 11 and fixedly connected to the opening and closing shaft 11; and a second rotating gear 13, which is fixedly connected to the opening and closing rod 6 and meshes with the first rotating gear 12.

[0059] During operation, the opening and closing motor 10 is turned on, which drives the opening and closing shaft 11, which is fixedly connected to the output end of the opening and closing motor 10, to rotate. This causes the first rotating gear 12, which is fixedly connected to the opening and closing shaft 11, to rotate, thereby driving the second rotating gear 13, which meshes with the first rotating gear 12, to rotate. The second rotating gear 13 then drives the opening and closing rod 6 to rotate on the feed pipe 4, which in turn drives the opening and closing plate 7, which is fixedly connected to the opening and closing rod 6, to rotate inside the feed pipe 4. This allows the demulsifier to flow into the oil delivery pipe 3 through the gap between the opening and closing plate 7 and the feed pipe 4, where it mixes with the crude oil.

[0060] Reference Figure 4 In a preferred embodiment, the stirring mechanism includes: a fixed frame 14, which is disposed on the oil supply pipe 3 and fixedly connected to the oil supply pipe 3; a stirring frame 15, which is fixedly connected to the fixed frame 14; a stirring motor 16, which is fixedly connected to the stirring frame 15; a stirring shaft 17, which is fixedly connected to the output end of the stirring motor 16; a stirring disc 18, which is disposed on the stirring shaft 17 and fixedly connected to the stirring shaft 17; and a transmission component, which is disposed on the stirring disc 18.

[0061] When in operation, the stirring motor 16 is started, which drives the stirring shaft 17, which is fixedly connected to the output end of the stirring motor 16, to rotate, causing the stirring disc 18, which is fixedly connected to the stirring shaft 17, to rotate.

[0062] Reference Figure 4 In a preferred embodiment, the transmission components include: a first transmission shaft 19, eccentrically mounted on the stirring plate 18 and fixedly connected to the stirring plate 18; a transmission plate 20, rotatably connected to the first transmission shaft 19; a second transmission shaft 21, rotatably connected to the transmission plate 20; a rotating component, mounted on the oil supply pipe 3; a rotating rod 22, mounted on the oil supply pipe 3 and rotatably connected to the oil supply pipe 3; a rotating disk 23, mounted on the rotating rod 22 and fixedly connected to the rotating rod 22, and the second transmission shaft 21 is eccentrically fixedly connected to the rotating disk 23; and a fixing component, mounted on the rotating rod 22.

[0063] During operation, the transmission plate 20, which is rotatably connected to the first transmission shaft 19, rotates, causing the rotating disk 23, which is fixedly connected to the second transmission plate 20, to rotate, which in turn causes the rotating rod 22, which is fixedly connected to the rotating disk 23, to rotate on the oil pipeline 3.

[0064] Reference Figure 4 In a preferred embodiment, the fixing component includes: a fixing cylinder 24, which is disposed on the rotating rod 22 and fixedly connected to the rotating rod 22; and fixing blades 25, which are multiple and are evenly disposed on the fixing cylinder 24 and fixedly connected to the fixing cylinder 24.

[0065] During operation, the fixed cylinder 24, which is fixedly connected to the rotating rod 22, rotates, which in turn drives the fixed blade 25, which is fixedly connected to the fixed cylinder 24, to rotate. When the crude oil and the demulsifier pass through the rotating fixed blade 25, the fixed blade 25 stirs and mixes the crude oil and the demulsifier.

[0066] Working principle: When in use, first turn on the opening and closing motor 10, which drives the opening and closing shaft 11 fixedly connected to the output end of the opening and closing motor 10 to rotate, so that the first rotating gear 12 fixedly connected to the opening and closing shaft 11 rotates, thereby driving the second rotating gear 13 meshing with the first rotating gear 12 to rotate, so that the second rotating gear 13 drives the opening and closing rod 6 to rotate on the feed pipe 4, and drives the opening and closing plate 7 fixedly connected to the opening and closing rod 6 to rotate inside the feed pipe 4, so that the demulsifier flows into the oil delivery pipe 3 through the gap between the opening and closing plate 7 and the feed pipe 4, and mixes with the crude oil, thereby realizing the control of the dosage of the demulsifier;

[0067] Next, the stirring motor 16 is started, which drives the stirring shaft 17, which is fixedly connected to the output end of the stirring motor 16, to rotate. This causes the stirring disc 18, which is fixedly connected to the stirring shaft 17, to rotate, thereby driving the transmission plate 20, which is rotatably connected to the first transmission shaft 19, to rotate. This causes the rotating disc 23, which is fixedly connected to the second transmission plate 20, to rotate, driving the rotating rod 22, which is fixedly connected to the rotating disc 23, to rotate on the oil pipeline 3. This causes the fixed cylinder 24, which is fixedly connected to the rotating rod 22, to rotate, driving the fixed blade 25, which is fixedly connected to the fixed cylinder 24, to rotate. When the crude oil and the demulsifier pass through the rotating fixed blade 25, the fixed blade 25 stirs and mixes the crude oil and the demulsifier, thereby making the crude oil and the demulsifier more uniformly mixed and improving the dehydration and upgrading efficiency of the crude oil.

[0068] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
