Description

Technical Field

[0001] This utility model relates to the field of reaction vessel equipment technology, specifically a hydrogenation reaction vessel with material mixing function. Background Technology

[0002] In hydrogenation reactions, the materials typically include hydrogen, reactants, and possibly catalysts. Thoroughly mixing these materials through a mixing mechanism is fundamental to ensuring the smooth progress of the reaction.

[0003] A search revealed a hydrogenation reactor with material mixing function disclosed in Chinese patent CN210700138U. Through the coordinated action of a base box, a bottom plate, a vibration motor, a fixing rod, a spring, a support plate, a first drive motor, a rotating column, and a stirring plate, and through the operation of the vibration motor and the first drive motor, the reactor can ensure that the reactants are fully mixed with hydrogen, thereby ensuring the purity of the reaction product and achieving high working quality.

[0004] However, in existing technologies, the size of the stirring plate is fixed. Since the density, viscosity, and particle size of the materials in the hydrogenation reaction vary, the stirring plate cannot generate sufficient shear and driving forces to ensure adequate material flow and mixing. This results in poor material flowability, a reduced reaction rate, and reduced mixing efficiency. To address the problem of existing technologies where the size of the stirring plate cannot be adjusted according to actual conditions, thus affecting mixing efficiency, this application proposes an adjustable sliding plate on the stirring plate. This allows for adjustment of the sliding plate's position based on actual conditions, thereby changing the stirring length and improving mixing efficiency and effectiveness. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The existing technology has shortcomings and defects, such as the fixed size of the stirring plate, which makes it difficult for the stirring plate to generate sufficient shear force and pushing force to make the material flow and mix fully, resulting in poor material flowability, reduced reaction rate, and reduced mixing efficiency.

[0006] The present invention discloses a hydrogenation reactor with material mixing function, comprising a tank body, a tank cover, a sleeve rotatably mounted on the tank cover, a rotating shaft rotatably mounted on the sleeve, a stirring plate mounted on the outside of the sleeve, a sliding plate mounted on the stirring plate, and a pushing component disposed between the sliding plate and the rotating shaft.

[0007] Furthermore, the pushing assembly includes a threaded cylinder, one end of which is rotatably mounted on the stirring plate, and the other end of which is driven onto the sleeve. The threaded cylinder is threadedly connected to the sliding plate. A first bevel gear is mounted on the threaded cylinder, and a second bevel gear is mounted on the rotating shaft. The first bevel gear and the second bevel gear mesh and drive each other.

[0008] Furthermore, a cavity is provided inside the sleeve, and both the first bevel gear and the second bevel gear are disposed in the cavity. A sealing ring is provided between the threaded cylinder and the sleeve, and the sleeve is coaxially disposed with the rotating shaft.

[0009] Furthermore, a connecting rod is slidably disposed on the threaded cylinder, one end of the connecting rod is fixedly connected to the sliding plate, and the connecting rod is coaxially disposed with the threaded cylinder.

[0010] Furthermore, a fixing frame is installed on the upper end of the can lid, and a limiting shaft is slidably installed on the fixing frame, with one end of the limiting shaft being inserted into the sleeve.

[0011] Furthermore, a scraper is provided between the sleeve and the inner wall of the tank, and the scraper is connected to the sleeve by fixing bolts. The scraper is a square frame.

[0012] Furthermore, a triangular block is provided between the stirring plate and the sleeve, and the triangular block is fixedly installed on the sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with components such as a rotating shaft, a sleeve, a threaded cylinder, and a sliding plate. During operation, the rotating shaft, sleeve, and threaded cylinder components work together to adjust the rotation of the rotating shaft. The meshing of bevel gears drives the threaded cylinder to rotate, and the threaded cylinder pushes the sliding plate to move on the stirring plate. This allows the stirring length to be changed according to actual needs, thereby improving the mixing efficiency and effect of hydrogen, reactants, and possible catalysts in the tank.

[0015] 2. This utility model incorporates components such as a connecting rod, a triangular block, and a scraper. During operation, the triangular block enhances the connection stability between the mixing plate and the sleeve, preventing stress concentration and damage. The connecting rod connects one end of the sliding plate to the threaded cylinder, improving the force distribution on the sliding plate and increasing its stability during operation. The scraper expands the mixing range, preventing material accumulation on the inner wall of the tank. Attached Figure Description

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 As shown, the hydrogenation reactor with material mixing function of this utility model includes a tank body 1, a tank cover 2 on the tank body 1, a sleeve 4 rotatably mounted on the tank cover 2, a sealing ring between the sleeve 4 and the tank cover 2, a servo motor 1 on one side of the sleeve 4, a rotating shaft 3 rotatably mounted on the sleeve 4, a servo motor 2 on the power end of the rotating shaft 3, the servo motor 1 and the servo motor 2 do not affect each other during operation, a stirring plate 6 is mounted on the outside of the sleeve 4, a sliding plate 7 is mounted on the stirring plate 6, and a pushing component is provided between the sliding plate 7 and the rotating shaft 3.

[0024] Combination Figure 2 , Figure 4 As shown, the pushing assembly includes a threaded cylinder 8, one end of which is rotatably mounted on the stirring plate 6, and the other end of which is driven onto the sleeve 4. The threaded cylinder 8 is threadedly connected to the slide plate 7. A bevel gear 9 is mounted on the threaded cylinder 8, and a bevel gear 10 is mounted on the rotating shaft 3. The bevel gear 9 and the bevel gear 10 mesh and drive each other, controlling the rotation of the threaded cylinder 8. The threaded cylinder 8 pushes the slide plate 7 to move on the stirring plate 6. By adjusting the rotation direction of the threaded cylinder 8, the movement direction of the slide plate 7 on the stirring plate 6 is changed.

[0025] In this embodiment, a cavity 5 is provided inside the sleeve 4, and both bevel gear 1 9 and bevel gear 2 10 are disposed in the cavity 5. A sealing ring is provided between the threaded cylinder 8 and the sleeve 4, and the sleeve 4 is coaxially disposed with the rotating shaft 3. The cavity 5 protects bevel gear 1 9 and bevel gear 2 10, so as to avoid affecting the meshing between bevel gear 1 9 and bevel gear 2 10.

[0026] A connecting rod 12 is slidably mounted on the threaded cylinder 8. One end of the connecting rod 12 is fixedly connected to the slide plate 7. The connecting rod 12 is coaxially mounted with the threaded cylinder 8. When the slide plate 7 is pushed by the threaded cylinder 8, the slide plate 7 drives the connecting rod 12 to move. One end of the connecting rod 12 slides on the threaded cylinder 8 and maintains the connection between the slide plate 7 and the threaded cylinder 8 through the connecting rod 12, thereby improving the stability of the slide plate 7.

[0027] Combination Figure 2 , Figure 3 As shown, a fixing frame 13 is installed on the upper end of the can lid 2. A limiting shaft 14 is slidably installed on the fixing frame 13. One end of the limiting shaft 14 is inserted into the sleeve 4. When adjusting the overall length between the stirring plate 6 and the sliding plate 7, the limiting shaft 14 needs to be inserted into the sleeve 4 first, so as to limit the position of the sleeve 4 and prevent the sleeve 4 from rotating with the rotating shaft 3.

[0028] In a preferred embodiment, a scraper 15 is provided between the sleeve 4 and the inner wall of the tank 1. The scraper 15 and the sleeve 4 are connected by fixing bolts. The scraper 15 is a square frame. The scraper 15 increases the stirring range, thereby preventing the material from accumulating at the corner of the tank 1.

[0029] like Figure 4 As shown, a triangular block 11 is provided between the stirring plate 6 and the sleeve 4. The triangular block 11 is fixedly installed on the sleeve 4. The connection stability between the stirring plate 6 and the sleeve 4 is increased by the triangular block 11, and the force-bearing area at the corner of the stirring plate 6 is increased, thereby improving the stability of the stirring plate 6 during the working process.

[0030] The implementation principle is as follows: When it is necessary to adjust the stirring length, firstly, the limiting shaft 14 is inserted into the sleeve 4, and then the servo motor 2 is controlled to work. The servo motor 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the bevel gear 10 to rotate, the bevel gear 10 drives the meshing bevel gear 9 to rotate, the bevel gear 9 drives the threaded cylinder 8 to rotate, and the threaded cylinder 8 pushes the slide plate 7 to move on the stirring plate 6, thereby adjusting the overall length between the slide plate 7 and the stirring plate 6. When the slide plate 7 is adjusted to the preset position, the servo motor 2 is stopped. Then, the limiting shaft 14 is pulled out from the sleeve 4, and the servo motor 1 is controlled to drive the sleeve 4 to rotate. The sleeve 4 drives the stirring plate 6 and the slide plate 7 to rotate, thereby realizing the mixing and stirring of the materials in the tank 1.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
