Detailed implementation manners

[0051] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0052] The present invention discloses a reaction kettle and a working method capable of improving the crude oil stirring efficiency between the transmission shaft and the edge of the stirring paddle.

[0053] In the first aspect as shown in Figure 1 the reaction kettle includes: a kettle body, a power device 1, a first stirring device 2, a second stirring device 3, and a plurality of third stirring devices 4.

[0054] Since the improvement focus of this application is on the power device 1, the first stirring device 2, the second stirring device 3, and the third stirring device 4, the kettle body is not numbered.

[0055] As shown in Figure 1 at the top of the kettle body, a feed inlet is provided, at the bottom, a discharge outlet is provided, its side wall is a sandwich wall, and an air inlet and an air outlet are provided on the sandwich wall. The crude oil of petroleum enters the kettle body from the feed inlet, and after stirring for a predetermined time, the crude oil that has completed the stirring process is discharged from the discharge outlet. When performing the stirring process, a fluid such as high-temperature steam or high-temperature oil liquid is input into the sandwich wall from the air inlet, and the high-temperature steam or high-temperature oil liquid and other fluids in the sandwich wall are discharged from the air outlet, realizing the circulation of the high-temperature steam or high-temperature oil liquid and other fluids in the sandwich wall to heat the crude oil of petroleum in the reaction kettle.

[0056] The connection of the power device 1 with the kettle body.

[0057] One end of the first stirring device 2 is connected to the power device 1, and the other end extends a predetermined distance into the kettle body from the power device 1, and a first stirring paddle 22 is provided at its extended end.

[0058] One end of the second stirring device 3 is connected to the power device 1, and the other end extends a predetermined distance into the kettle body from the power device 1, and its extended end is inserted and cooperated with the first stirring device 2, and a second stirring paddle 32 is provided at its extended end.

[0059] The third stirring device 4 is circumferentially equally divided and installed outside the first stirring device 2, and it is provided with a third stirring paddle 42.

[0060] Working principle: As Figure 2 shown, in the working state, the path formed by the power device 1 driving the first stirring paddle 22 to rotate forms a first rotating cylinder.

[0061] The path formed by the power device 1 driving the second stirring paddle 32 to rotate forms a second rotating cylinder.

[0062] The first stirring device 2 drives the third stirring device 4 to revolve. When the first stirring device 2 is displaced to a predetermined position, the third stirring device 4 abuts against the second stirring device 3. At this time, the second stirring device 3 exerts a rotating force on the third stirring device 4, and the path formed by the second stirring device 3 driving the third stirring device 4 to rotate forms a third rotating cylinder.

[0063] The second rotating cylinder is sleeved on the first rotating cylinder, the third rotating cylinder revolves along the path of the second rotating cylinder, and the path of the third rotating cylinder intersects with the path of the first rotating cylinder.

[0064] By arranging the third stirring device 4 between the first stirring device 2 and the second stirring device 3, the contact area with the crude oil is increased, and the first stirring device 2 is used to drive the third stirring device 4 to revolve. By driving the third stirring device 4 to rotate through the second stirring device 3, the stirring speed of the crude oil in the second rotating cylinder of the second stirring device 3 can be increased. That is, without setting a power source in the reaction kettle, a rotating force is increased between the transmission shaft and the edge of the stirring paddle, the stirring efficiency of the crude oil is improved, and at the same time, the problems of increased failure rate of the power source and the power source being easily damaged by high temperature and difficult to maintain in the reaction kettle are solved.

[0065] In the further embodiment of the first aspect as Figure 2 shown, the rotating directions of the first stirring device 2 and the second stirring device 3 are opposite.

[0066] By rotating in the opposite direction, the relative force received by the crude oil between the first rotating cylinder and the second rotating cylinder can be increased, thereby improving the processing efficiency of the crude oil between the first rotating cylinder and the second rotating cylinder.

[0067] Moreover, the reverse rotation can also make the third stirring device 4 intermittently abut against the second stirring device 3, thereby achieving the effect of the second stirring device 3 driving the third stirring device 4 to rotate.

[0068] In a further embodiment of the first aspect, the rotational speed of the first stirring device 2 is greater than that of the second stirring device 3.

[0069] By increasing the rotational speed of the first stirring device 2, the problem that the angular velocity acting force of the transmission shaft is low and the crude oil cannot be sufficiently stirred can be solved.

[0070] Due to the speed difference, when the first stirring device 2 and the second stirring device 3 rotate, the third stirring device 4 can be intermittently abutted against the second stirring device 3, thereby achieving the effect that the second stirring device 3 drives the third stirring device 4 to rotate.

[0071] In the further embodiment of the first aspect as Figure 1 shown, the power device 1 includes: a first power source 11 and a second power source 12.

[0072] The first power source 11 is installed at the top end of the kettle body and is connected to the first stirring device 2.

[0073] The second power source 12 is installed at the bottom end of the kettle body and is connected to the second stirring device 3.

[0074] By installing the first power source 11 and the second power source 12 at both ends of the kettle body respectively, the distance from the power source to the stirring paddle of the stirring device can be shortened, power loss can be reduced, and the stirring requirement of the crude oil can be met when the power source selects a reducer and a motor with lower cost, thereby reducing the overall production cost of the reactor.

[0075] Moreover, especially by installing the second power source 12 at the bottom end of the kettle body, the second stirring device 3 can be directly installed at the bottom end of the kettle body, avoiding the problem in the prior art that the distance from the power source to the stirring paddle of the stirring device is too long, and the crude oil deposited at the bottom end of the kettle body due to gravity causes too much resistance to the stirring paddle of the stirring device, resulting in a low service life of the stirring paddle in the prior art.

[0076] In the further embodiment of the first aspect as Figure 1 and 2 shown, the first stirring device 2 includes: a first transmission shaft 21 and a first stirring paddle 22.

[0077] One end of the first transmission shaft 21 is connected to the first power source 11, and the other end extends a predetermined distance into the kettle body from the first power source 11, and a positioning cavity is provided at its extended end.

[0078] The first stirring paddle 22 is arranged at the extended end of the first transmission shaft 21 and extends a predetermined distance in a direction away from the first transmission shaft 21.

[0079] The second stirring device 3 includes: a second transmission shaft 31, a second stirring paddle 32 and a plurality of dial rods 33.

[0080] One end of the second transmission shaft 31 is connected to the second power source 12, and the other end extends a predetermined distance into the kettle body from the second power source 12. The extended end of the second transmission shaft 31 is inserted and fitted with the positioning cavity of the first transmission shaft 21, and the coaxiality of the second transmission shaft 31 and the first transmission shaft 21 is within a predetermined range.

[0081] The second stirring paddle 32 is arranged at the extended end of the second transmission shaft 31 and extends a predetermined distance away from the second transmission shaft 31.

[0082] The lever 33 is arranged at the extended end of the second stirring paddle 32 in a circumferential equally divided manner.

[0083] The third stirring device 4 includes: a third transmission shaft 41 and a third stirring paddle 42.

[0084] The third transmission shaft 41 is arranged at the extended end of the first stirring paddle 22 in a circumferential equally divided manner.

[0085] The third stirring paddle 42 is rotatably connected to the third transmission shaft 41 and extends a predetermined distance away from the third transmission shaft 41.

[0086] The distance from the third transmission shaft 41 to the lever 33 is greater than the distance from the third transmission shaft 41 to the first transmission shaft 21, and the third stirring paddle 42 is in abutting fit with the lever 33.

[0087] By making the distance from the third transmission shaft 41 to the lever 33 greater than the distance from the third transmission shaft 41 to the first transmission shaft 21, it is possible to avoid the third stirring paddle 42 contacting the first transmission shaft 21 while the third stirring paddle 42 is in abutting contact with the lever 33, and it is possible to ensure that the third stirring paddle 42 rotates around the third transmission shaft 41.

[0088] By making the extended end of the second transmission shaft 31 inserted and fitted with the positioning cavity of the first transmission shaft 21, it is possible to make the coaxiality of the second transmission shaft 31 and the first transmission shaft 21 within a predetermined range. Furthermore, when the third transmission shaft 41 revolves around the first transmission shaft 21, the distance between the third transmission shaft 41 and the second transmission shaft 31 remains unchanged, and furthermore, it is ensured that the third stirring paddle 42 can contact the first transmission shaft 21.

[0089] By arranging a positioning cavity at the bottom end of the first transmission shaft 21, it is possible to avoid the cleaning liquid accumulating in the positioning cavity during maintenance and cleaning.

[0090] In a further embodiment of the first aspect as Figure 4 shown, the reaction kettle further includes: a positioning assembly 5.

[0091] The positioning assembly 5 includes: a positioning bearing 51 and a positioning ring 52.

[0092] The positioning bearing 51 is installed in the positioning cavity of the first transmission shaft 21.

[0093] The positioning ring 52 is inserted and matched with the positioning bearing 51, and its inner wall is a frustum-shaped inner wall.

[0094] The extending end of the second transmission shaft 31 is a frustum-shaped structure or a conical structure, and the extending end of the second transmission shaft 31 is inserted into the positioning ring 52.

[0095] Through the positioning ring 52 with a frustum-shaped inner wall and the extending end of the second transmission shaft 31 being a frustum-shaped structure or a conical structure, the self-guidance of the extending end of the second transmission shaft 31 can be realized by using the slope of the frustum-shaped structure, so that the extending end of the second transmission shaft 31 can be quickly inserted into the positioning ring 52 to achieve quick positioning. Through the positioning bearing 51, when there is a rotational speed difference between the first transmission shaft 21 and the second transmission shaft 31 or the rotational directions of the first transmission shaft 21 and the second transmission shaft 31 are opposite, the positioning and connection of both the first transmission shaft 21 and the second transmission shaft 31 can be ensured.

[0096] In Figure 1 In a further embodiment of the first aspect as shown, the first stirring paddle 22 is composed of a plurality of first stirring rods in an inverted mountain shape or a printed character shape. The first stirring rods are arranged at equal circumferential intervals around the first transmission shaft 21. As Figure 1 shown in the embodiment, the first stirring paddle 22 is composed of a plurality of first stirring rods in an inverted mountain shape. In the embodiment where the first stirring paddle 22 is composed of a plurality of first stirring rods in a printed character shape, the first stirring rods in an inverted mountain shape can be installed on the first transmission shaft 21 first, and then the third stirring rod can be installed at the bottom end of the first stirring rod in an inverted mountain shape, and then the first stirring rod in a mountain shape can be installed at the bottom end of the third stirring rod to form the first stirring rod in a printed character shape.

[0097] The second stirring paddle 32 is composed of a plurality of second stirring rods in a mountain shape. The second stirring rods are arranged at equal circumferential intervals around the second transmission shaft 31.

[0098] In the working state, the top end of the second stirring rod is located between one-third and two-thirds in the direction from the bottom end of the first stirring rod to the top end of the inner wall of the kettle body.

[0099] The dial rod 33 is installed at the top end of the second stirring rod.

[0100] By making the top end of the second stirring rod located between one-third and two-thirds of the first stirring rod in the front projection view in the working state, when the rotational directions of the first stirring device 2 and the second stirring device 3 are opposite, the second rotating cylinder can be sleeved on the first rotating cylinder, and the rotational force applied to the crude oil between the first rotating cylinder and the second rotating cylinder is increased.

[0101] In Figure 1 and 3 In a further embodiment of the first aspect as shown, the third transmission shaft 41 includes: a plurality of rotary bearings 412 and a sleeve 411.

[0102] The rotating bearing 412 is sleeved on the first stirring rod.

[0103] The sleeve 411 is sleeved on the rotating bearing 412.

[0104] Wherein, the third stirring paddle 42 is connected with a spiral belt on the outer wall of the sleeve 411.

[0105] The shift rods 43 are arranged at equal circumferential intervals around the sleeve 411. The shift rods 43 extend a predetermined distance away from the sleeve 411, and the shift rods 43 are in abutting cooperation with the shift levers 33.

[0106] The number of the shift rods 43 is matched with the number of the shift levers 33.

[0107] As Figure 2 shown, each third stirring device 4 includes six shift rods 43, and each second stirring device 3 includes twelve shift levers 33, that is, the number ratio of the shift rods 43 to the shift levers 33 is 1:2.

[0108] As Figure 2 shown, by making the number ratio of the shift rods 43 to the shift levers 33 be 1:2, it can be ensured that each third stirring device 4 has a shift rod 43 in abutting connection with a shift lever 33. When the first stirring device 2 and the second stirring device 3 rotate and work, the third stirring device 4 can also be in a rotating state. By arranging the third stirring paddle 42 as a spiral belt, the petroleum at the bottom layer of the reaction kettle can be stirred to the top end of the reaction kettle, so that the petroleum can be fully stirred.

[0109] In a second aspect, based on the first aspect, the working method of the reaction kettle includes: S1. After loading a predetermined amount of crude oil into the kettle body, close the kettle body, and start the first power source 11 and the second power source 12 to work for a predetermined time.

[0110] S2. The first power source 11 drives the first stirring paddle 22 to rotate around the first transmission shaft 21, so that the path formed by the rotation of the first stirring paddle 22 forms a first rotating cylinder.

[0111] The second power source 12 drives the second stirring paddle 32 to rotate around the second transmission shaft 31, so that the path formed by the rotation of the second stirring paddle 32 forms a second rotating cylinder.

[0112] Wherein, there is a predetermined rotational speed difference between the first stirring paddle 22 and the second stirring paddle 32, and / or the rotation directions of the first stirring paddle 22 and the second stirring paddle 32 are opposite.

[0113] S3. When the first stirring paddle 22 rotates around the first transmission shaft 21, the first stirring paddle 22 drives the third transmission shaft 41 and the third stirring paddle 42 to revolve around the first transmission shaft 21.

[0114] S4. When the third stirring paddle 42 revolves around the first transmission shaft 21 to a predetermined position, the third stirring paddle 42 abuts against the lever 33, and the lever 33 drives the third stirring paddle 42 to rotate around the third transmission shaft 41, so that the path of rotation of the third stirring paddle 42 forms a third rotating cylinder.

[0115] S5. After repeating the sequential operations of S2 to S4 for a predetermined time, the first power source 11 and the second power source 12 are turned off, and then the crude oil in the kettle body is taken out.

[0116] Among them, when repeating the sequential operations of S2 to S4, the crude oil in the kettle body can also be heated to a predetermined temperature.
