Description

Technical Field

[0001] This utility model relates to the field of petroleum viscosity reduction technology, specifically to a reaction device for petroleum viscosity reduction. Background Technology

[0002] Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Petroleum is primarily used as fuel and gasoline, and it is also a raw material for many chemical industrial products such as solvents, fertilizers, pesticides, and plastics. In modern society, petroleum has a wide range of uses. However, due to its high viscosity and poor flowability, petroleum is prone to clogging pipelines during transportation, which hinders its delivery. Increasing pump pressure significantly increases costs and reduces profits. Therefore, it is necessary to treat petroleum to reduce its viscosity.

[0003] Chinese patented invention CN210787346U discloses a reaction device for reducing oil viscosity, including a reaction tank and a stirring rod. Support feet are provided on the outer walls of the front left and right sides and the middle outer wall of the rear end of the reaction tank. A sealing connection block is separated from the L-shaped oil outlet pipe and oil inlet pipe, respectively. Both the L-shaped oil outlet pipe and oil inlet pipe have internally threaded connectors on their inner walls. The sealing connection block is rotatably and fixedly connected to the internally threaded oil inlet pipe and the internally threaded L-shaped oil outlet pipe via an externally threaded hollow connecting pipe. When the operator performs the sealing connection, the sealing gasket and the fixing pipe are directly inserted into the inner wall of the external connecting pipe and make tight contact with it. This prevents the sealing gasket from folding or breaking when the connection is fixed with a fixing nut, and also facilitates the replacement of the sealing connection block, thus improving the overall sealing performance of the reaction tank.

[0004] However, the device still has some problems. In actual use, the reaction device adopts a unidirectional stirring method. Although this stirring method can achieve the mixing of oil and reagent to a certain extent, the unidirectional stirring direction leads to low stirring efficiency and long mixing time. Specifically, unidirectional stirring often fails to fully break the interface between oil and reagent, resulting in uneven mixing and excessively high or low reagent concentration in some areas, which affects the viscosity reduction effect. Therefore, we proposed a reaction device for oil viscosity reduction to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a reaction device for reducing the viscosity of petroleum, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A reaction apparatus for reducing oil viscosity includes a support box with an open bottom. A reaction vessel is rotatably connected to the top of the support box. An external gear ring is fixedly connected to the bottom of the reaction vessel, extending into the support box. A first motor is fixedly connected to the top of the support box.

A connecting ring is fixedly connected to the reaction vessel. Multiple limiting rods are fixedly connected to the bottom of the connecting ring in an annular shape. A circular groove is formed on the top of the support box, and the limiting rods are slidably connected to the circular groove. A second motor is fixedly connected to the top of the reaction vessel. A stirring rod is rotatably connected between the inner walls of both sides of the reaction vessel. The top of the stirring rod extends outside the reaction vessel and is fixedly connected to the output shaft of the second motor.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a reaction device for reducing the viscosity of petroleum, which has the following features:

[0017] Beneficial effects:

[0018] This invention involves pouring petroleum and reagents into a reaction vessel through a feed pipe, then fixing a rubber stopper to the feed pipe. A first motor and a second motor are then activated. The first motor drives an external gear ring to rotate via gears, which in turn rotates the reaction vessel. The reaction vessel, via a connecting ring, causes a limiting rod to slide on a circular groove. As the reaction vessel rotates, the petroleum and reagents inside are also subjected to centrifugal force and begin to rotate forward. Simultaneously, the second motor drives a stirring rod to rotate in the opposite direction. This counter-rotation of the stirring rod, combined with the forward rotation of the reaction vessel and its contents, creates a convection effect. This convective mixing significantly improves the mixing efficiency and uniformity of the materials, thereby enhancing viscosity reduction and shortening the reaction time.

[0025] Example

[0026] like Figure 1-4As shown, an embodiment of the present invention discloses a reaction device for reducing oil viscosity, comprising a support box 1 with an open bottom. A reaction vessel 2 is rotatably connected to the top of the support box 1. An external gear ring 3 is fixedly connected to the bottom of the reaction vessel 2 extending into the support box 1. A first motor 4 is fixedly connected to the top of the support box 1, and the output shaft of the first motor 4 extends into the support box 1 and is fixedly connected to a gear 5, which meshes with the external gear ring 3. A connecting ring 6 is fixedly connected to the reaction vessel 2, and multiple limiting rods 7 are fixedly connected to the bottom of the connecting ring 6 in an annular shape. A circular groove 8 is provided on the top of the support box 1, and the limiting rods 7 are slidably connected to the circular groove 8. A second motor 9 is fixedly connected to the top of the reaction vessel 2. A stirring rod 10 is rotatably connected between the inner walls of both sides of the reaction vessel 2, and the top end of the stirring rod 10 extends into the reaction vessel 2. The reaction tank 2 is externally and fixedly connected to the output shaft of the second motor 9. A discharge pipe 11 is connected to and fixedly attached to the bottom of the reaction tank 2, and a valve 12 is fixedly connected to the discharge pipe 11. A feed pipe 17 is connected to and fixedly attached to the top of the reaction tank 2. Petroleum and reagents are poured into the reaction tank 2 through the feed pipe 17, and a rubber stopper 18 is fixed to the feed pipe 17. The first motor 4 and the second motor 9 are started. The first motor 4 drives the outer gear ring 3 to rotate through the gear 5, and the outer gear ring 3 drives the reaction tank 2 to rotate. The reaction tank 2 drives the limiting rod 7 to slide on the circular groove 8 through the connecting ring 6. As the reaction tank 2 rotates, the petroleum and reagents inside it are also subjected to centrifugal force and begin to rotate forward. At the same time, the second motor 9 drives the stirring rod 10 to rotate in the opposite direction. The reverse rotation of the stirring rod 10 and the forward rotation of the reaction tank 2 and the materials inside form a convection effect. This convection mixing can significantly improve the mixing efficiency and uniformity between materials, thereby improving the viscosity reduction effect and reducing the reaction time.

[0027] In some embodiments, a rubber stopper 18 is movably contacted on the feed pipe 17.

[0028] In some embodiments, a reciprocating lead screw 14 is rotatably connected between the inner walls of the two sides of the reaction vessel 2, and a third motor 13 is fixedly connected to the top of the reaction vessel 2.

[0029] In some embodiments, the top end of the reciprocating lead screw 14 extends outside the reaction vessel 2 and is fixedly connected to the output shaft of the third motor 13, and a scraper 15 is threaded onto the reciprocating lead screw 14.

[0030] In some embodiments, a square rod 16 is fixedly connected between the inner walls of both sides of the reaction vessel 2. The square rod 16 is slidably connected to the scraper 15. The square rod 16 serves a positioning function.

[0031] In some embodiments, two L-shaped plates 19 are welded to the top of the support box 1, and two mounting holes 20 are opened on one side inner wall of the L-shaped plate 19. The L-shaped plate 19 serves as a support.

[0032] In terms of working principle or structural principle, during use, the entire device is fixed through the mounting holes 20 on the L-shaped plate 19. After fixing, the rubber stopper 18 is removed, and petroleum and reagents are poured into the reaction tank 2 through the feed pipe 17. The rubber stopper 18 is then fixed on the feed pipe 17. The first motor 4 and the second motor 9 are started. The first motor 4 drives the outer gear ring 3 to rotate through the gear 5. The outer gear ring 3 drives the reaction tank 2 to rotate. The reaction tank 2 drives the limiting rod 7 to slide on the circular groove 8 through the connecting ring 6. As the reaction tank 2 rotates, the petroleum and reagents inside it will also be affected by centrifugal force and begin to rotate in the forward direction. At the same time, the second motor 9 drives the stirring rod 10 to rotate in the reverse direction. The reverse rotation of the stirring rod 10 and the forward rotation of the reaction tank 2 and the materials inside it form a convection effect. This convective mixing can significantly improve the mixing efficiency and uniformity between materials, thereby improving the viscosity reduction effect and reducing the reaction time. The third motor 13 is started, which drives the reciprocating screw 14 to rotate. The reciprocating screw 14 drives the scraper 15 to move up and down on the square rod 16, so that the scraper 15 cleans the material adhering to the inner wall of the reaction tank 2.
