Description

Technical Field

[0001] The present invention relates to the technical field of stirring equipment, in particular to a jet mixer and a stirring reaction system. Background Art

[0002] In chemical production, the reaction process of materials is usually carried out in a reactor. When solid powder is added during production, gravity feeding is usually adopted from a silo, which has a slow feeding speed and is prone to generating dust. Powder materials tend to float on the liquid surface due to their low bulk density, affecting the mixing effect. Therefore, a jet mixer is used to allow the solid powder to enter the reactor under negative pressure. However, the existing structural design is unreasonable, and powder is easily accumulated in dead corners. At the same time, the feeding speed of the solid powder cannot be adjusted. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a jet mixer and a stirring reaction system.

[0004] The objective of the present invention is achieved through the following technical solutions: A jet mixer, comprising a first material pipe, a second material pipe, a first straight pipe and a gradually diverging pipe, the first material pipe and the second material pipe are connected, the second material pipe is connected to the first straight pipe, the first straight pipe is connected to the gradually diverging pipe, and the inner walls of the first material pipe, the second material pipe, the first straight pipe and the gradually diverging pipe have a smooth transition; the first material pipe and the second material pipe are connected by a thread, the bottom of the first material pipe includes a boss, the bottom of the second material pipe includes an inclined surface matching the boss, and a gap is left between the boss and the inclined surface; the first material pipe is connected to the feed port, and the second material pipe is connected to the liquid inlet.

[0005] Furthermore, the first material pipe includes a second straight pipe and a boss.

[0006] Furthermore, a sealing ring is provided at the connection between the first material pipe and the second material pipe.

[0007] Furthermore, the angles of the boss and the inclined surface are the same.

[0008] Furthermore, a wear-resistant layer is provided on the boss and the inclined surface.

[0009] Furthermore, the first material tube is provided with a scale and a rotation direction mark, and the scale indicates the distance between the boss and the inclined surface after rotation.

[0010] Furthermore, after the first material tube rotates, the gap distance ranges from 0.3 to 6 mm.

[0011] A stirring reaction system includes a reactor, wherein the bottom of the reactor is connected to a stirring pump via a pipeline, the stirring pump is connected via a pressure sensor, the pressure sensor is connected to a second material pipe of a jet mixer via a pipeline, the first material pipe of the jet mixer is connected to a silo via a valve, and the pressure sensor and the stirring pump are both electrically connected to a controller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The jet mixer provided by the present invention allows liquid material to be introduced into the second material pipe, while solid powder can be introduced into the first material pipe. Since the introduced liquid material will generate negative pressure at the bottom of the first material pipe when passing through the gap between the boss and the inclined surface, the solid material will be sucked into the reactor under the action of the negative pressure.

[0014] 2. The jet mixer provided by the present invention has smooth transitions in the inner walls of the first material pipe, the second material pipe, the first straight pipe and the gradually diverging pipe to prevent accumulation of solid powder.

[0015] 3. In the jet mixer provided by the present invention, the first material pipe and the second material pipe can rotate relative to each other, so the gap between the boss and the inclined surface can be adjusted, thereby adjusting the negative pressure at the bottom of the first material pipe, thereby adjusting the feeding speed of the solid material.

[0016] 4. The stirring reaction system provided by the present invention is provided with a pressure sensor. When the pressure sensor detects that the system pressure decreases, the controller controls the stirring pump to increase the speed and the flow head, thereby ensuring that the powder absorption height of the solid material remains unchanged and the entire system remains stable.

[0020] The present invention will be further described below with reference to the accompanying drawings and examples.

[0021] like Figure 1-2As shown, a jet mixer includes a first material pipe 310, a second material pipe 320, a first straight pipe 330 and a gradually diverging pipe 340, the first material pipe 310 and the second material pipe 320 are connected, the second material pipe 320 is connected to the first straight pipe 330, the first straight pipe 330 is connected to the gradually diverging pipe 340, and the inner walls of the first material pipe 310, the second material pipe 320, the first straight pipe 330 and the gradually diverging pipe 340 have a smooth transition; the first material pipe 310 and the second material pipe 320 are connected by threads, the bottom of the first material pipe 310 includes a boss 311, the bottom of the second material pipe 320 includes an inclined surface 321 that matches the boss 311, and a gap 350 is left between the boss 311 and the inclined surface 321; the first material pipe 310 is connected to the feed port 360, and the second material pipe 320 is connected to the liquid inlet 370.

[0022] The first feed pipe 310 includes a second straight pipe 312 and a boss 311. A sealing ring 380 is provided at the connection between the first feed pipe 310 and the second feed pipe 320. The boss 311 and the inclined surface 321 have the same angle. Both the boss 311 and the inclined surface 321 are provided with a wear-resistant layer. It should be noted that the entire boss 311 and the inclined surface 321 can also be made of a wear-resistant material to achieve the above function. The first feed pipe 310 is provided with a scale and a rotation direction indicator. The scale indicates the distance of the gap 350 between the boss 311 and the inclined surface 321 after rotation. After the first feed pipe is rotated, the distance of the gap 350 ranges from 0.3 to 6 mm.

[0023] It should be noted that when the present invention is working, liquid material is introduced into the second material pipe 320, and solid powder can be introduced into the first material pipe 310 at the same time. Since the introduced liquid material will generate negative pressure at the bottom of the first material pipe 311 when passing through the gap 350 between the boss 311 and the inclined surface 321, the solid material will be sucked into the reactor 100 under the action of the negative pressure. Furthermore, because the inner walls of the first material pipe, the second material pipe, the first straight pipe and the gradually expanding pipe have a smooth transition, the solid powder will not accumulate, and the overall use is more practical.

[0024] At the same time, the first material pipe 310 and the second material pipe 320 can rotate relative to each other, so the gap between the boss 311 and the inclined surface 321 can be adjusted, thereby adjusting the negative pressure at the bottom of the first material pipe 310, thereby adjusting the feeding speed of the solid material. When the gap is increased, the feeding speed is increased, and when the gap is decreased, the feeding speed is slowed down.

[0025] like Figure 3As shown, a stirring reaction system includes a reactor 100, the bottom of the reactor 100 is connected to a stirring pump 200 through a pipeline, the stirring pump 200 is connected through a pressure sensor 600, the pressure sensor 600 is connected to the second material pipe 302 of the jet mixer 300 through a pipeline, the first material pipe 301 of the jet mixer 300 is connected to the silo 500 through a valve 400, and the pressure sensor 600 and the stirring pump 200 are both electrically connected to the controller 700.

[0026] It should be noted that a pressure sensor 600 is provided in the system. When the user increases the gap in order to speed up the feeding speed of the solid material, the pressure sensor 600 will detect that the system pressure has decreased, and the controller 700 will control the stirring pump 200 to increase the speed and the flow head will increase, thereby ensuring that the powder absorption height of the solid material remains unchanged and the entire system remains stable, and vice versa. This will not be elaborated here.

[0027] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
