Description

Technical Field

[0001] This application relates to emulsion preparation and processing technology, and more particularly to an emulsion preparation apparatus. Background Technology

[0002] In the one-pot synthesis of N-phenyl-N-trichloromethylthiobenzenesulfonamide, aniline, soluble bicarbonate, catalyst, and water are mixed uniformly in a specific ratio to prepare an emulsion. Then, benzenesulfonyl chloride is added dropwise to the emulsion at 10℃-25℃ for a sustained reaction.

[0003] Existing emulsion preparation equipment adds aniline, soluble bicarbonate, catalyst and water quantitatively into a stirred tank at once. The immiscible phases are homogenized and emulsified by the shear force generated by the high-speed rotation of the homogenizing head to produce an emulsion.

[0004] In existing emulsion preparation devices, after bicarbonate crystal powder is added to the stirred tank, it sinks to the bottom. A homogenizing head is needed to continuously circulate and mix the emulsion for an extended period to ensure the bicarbonate crystal powder is completely and uniformly dissolved. Therefore, this not only affects the efficiency of emulsion preparation but also the dissolution effect of the bicarbonate crystal powder. Utility Model Content

[0005] This application provides an emulsion preparation apparatus to solve the problem in existing emulsion preparation apparatuses where bicarbonate crystal powder sinks to the bottom of the stirring tank, affecting the dissolution effect and emulsion preparation efficiency.

The upper end of the stirring tank is provided with a motor fixed by a fixing frame. The rotating shaft of the motor extends vertically into the stirring tank.

An electric telescopic rod is connected between the stator cavity and the fixing frame, so that the stator cavity slides up and down along the rotating shaft. The top of the stator cavity is provided with a cover that can be opened and closed.

[0007] Optionally, the rotating shaft is provided with a keyway along the axial direction, and the top and bottom surfaces of the stator cavity are respectively concentrically fixed with bearings. A sleeve is rotatably connected between the two bearings. The stator cavity is rotatably connected to the rotating shaft by the sleeve. The outer wall of the sleeve is fixed with rotor blades, and the inner wall of the sleeve is fixed with a key that can slide up and down along the keyway.

[0008] Optionally, a controller is installed on the fixing frame. The controller is electrically connected to the electric telescopic pole and is used to drive the electric telescopic pole to reciprocate at a uniform speed.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0020] like Figures 1-5 As shown, one embodiment of this application provides an emulsion preparation device, including a stirring tank 1 and a stator cavity 5 with mesh. The upper end of the stirring tank 1 is provided with a motor 3 fixed by a fixing frame 2. The rotating shaft 4 on the motor 3 extends vertically into the stirring tank 1. The stator cavity 5 is sleeved on the rotating shaft 4 and rotatably connected to it. The stator cavity 5 is provided with rotor blades 9 that can be driven to rotate by the rotating shaft 4. An electric telescopic rod 10 is connected between the stator cavity 5 and the fixing frame 2, so that the stator cavity 5 slides up and down along the rotating shaft 4. The top of the stator cavity 5 is provided with a cover 11 that can be opened and closed.

[0021] In use, a measured amount of water and aniline solution required for emulsifying the solution are injected into the mixing tank 1. Then, the stator cavity 5 is lifted upward along the rotating shaft 4 by the contraction of the electric telescopic rod 10, causing the stator cavity 5 to move out of the liquid surface. After opening the cover 11 at the top of the stator cavity 5, the soluble bicarbonate crystal powder required for emulsifying the solution is added into the stator cavity 5 through the opening at the cover 11. Then, the cover 11 is closed, and the stator cavity 5 is pushed downward by the electric telescopic rod 10 to move it into the liquid. The motor 3 is started, driving the rotor blades 9 inside the stator cavity 5 to rotate through the rotating shaft 4. The high-speed rotation of the rotor blades 9 generates negative pressure, continuously and rapidly drawing the liquid into the stator cavity 5 through the upper mesh, allowing the multiphase liquid to dissolve and mix with the bicarbonate crystal powder in the stator cavity 5. At the same time, the multiphase liquid is homogenized and emulsified before being discharged from the side wall and the lower mesh.

[0022] In this embodiment, the stator cavity 5 can move up and down along the rotating shaft 4 via the electric telescopic rod 10. After the stator cavity 5 is removed from the liquid surface, soluble bicarbonate crystal powder is added into the stator cavity 5. Water and aniline liquid are drawn into the stator cavity 5 through the mesh by the high-speed rotating rotor blades 9 for homogenization and emulsification. This allows the bicarbonate crystal powder to dissolve more quickly and evenly in the emulsion circulating into the stator cavity 5, improving the dissolution effect of the soluble bicarbonate crystal powder during the addition process.

[0023] In one possible implementation, the rotating shaft 4 is provided with a keyway 7 along the axial direction, the top and bottom surfaces of the stator cavity 5 are respectively concentrically fixed with bearings 8, and a sleeve 6 is rotatably connected between the two bearings 8. The stator cavity 5 is rotatably connected to the rotating shaft 4 by the sleeve 6. The outer wall of the sleeve 6 is fixed with rotor blades 9, and the inner wall of the sleeve 6 is fixed with a key that can slide up and down along the keyway 7.

[0024] The rotating shaft 4 passes through the top bearing 8, the sleeve 6 and the bottom bearing 8 in sequence, the keys fixed on the inner wall of the sleeve 6 are inserted into the keyways 7 on the rotating shaft 4 and can slide up and down, and the sleeve 6 and the bearings 8 are rotationally connected with the stator cavity 5. The rotating shaft 4 drives the sleeve 6 to rotate the rotor blades 9 through the keyways 7 and the inserted keys, without affecting the stator cavity 5 to slide up and down through the electric telescopic rod 10.

[0025] In a possible implementation, the fixed frame 2 is provided with a controller 12, which is electrically connected with the electric telescopic rod 10 and is used to drive the electric telescopic rod 10 to reciprocate at a uniform speed.

[0026] While the motor 3 rotates the rotor blades 9 through the rotating shaft 4, the controller 12 can drive the electric telescopic rod 10 to reciprocate up and down along the rotating shaft 4, so as to change the depth position of the stator cavity 5 in the liquid and further improve the emulsification and mixing efficiency.

[0027] In a possible implementation, the bearing 8 on the top surface of the stator cavity 5 is rotationally connected with a rotating drum 13 sleeved on the rotating shaft 4, the paddle wheel 14 is sleeved on the outer wall of the rotating drum 13, and the keys that can slide up and down along the keyways 7 are fixed on the inner wall of the rotating drum 13.

[0028] The rotating drum 13 sleeved on the rotating shaft 4 can rotate synchronously with the rotating shaft 4, so as to drive the paddle wheel 14 to push the emulsion to the stator cavity 5 and accelerate the circulation and mixing of the emulsion.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
