Description

Technical Field

[0001] The present invention relates to a mixing device, and more particularly to an impinging stream high-efficiency mixing device. Background Art

[0002] Impinging Stream is an important fluid mixing intensification technology, which is particularly effective for diffusion-controlled chemical processes. After years of development, the continuous phase of impinging stream has been extended from gas phase to liquid phase, thus highlighting the advantage of impinging stream in intensifying micro-mixing of liquid phase.

[0003] For the preparation of latex, a mixing device based on stirring is currently used to stir and mix water and colloid to obtain latex. However, the mixing relying only on stirring results in low mixing efficiency, so the mixing time has to be prolonged. But too long stirring time will cause the colloid to solidify, which also affects the preparation of latex. Therefore, an impinging stream high-efficiency mixing device capable of quickly mixing water and colloid is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an impinging stream high-efficiency mixing device capable of quickly mixing water and colloid.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: It includes a main body, a main motor and a main shaft. A main mixing chamber is arranged in the main body. The main motor is arranged on the main body and drives the main shaft to rotate vertically in the main mixing chamber. It also includes a side body, a side motor, a side shaft, a side mixer and a main mixer. The main mixer is arranged on the main body and has a spraying area for spraying colloid horizontally. A water inlet for water to enter is arranged on the main body, and the water vertically passes through the spraying area. A side mixing chamber is arranged in the side body. The side body is arranged horizontally on the main body and the side mixing chamber is communicated with the main mixing chamber. The side body is located above the spraying area. The side motor is arranged on the side body and drives the side shaft to rotate in the side mixing chamber. The side mixer is arranged on the side shaft and sucks the liquid in the side mixing chamber and sprays it vertically. A latex outlet for the liquid to flow out of the side mixing chamber is arranged at the top of the side body. The rotational speed of the main motor is 2900 revolutions per minute and the power is 22 kw. The rotational speed of the side motor is 2900 revolutions per minute and the power is 15 kw.

[0006] By adopting the above technical solution, when preparing latex, water continuously flows into the main mixing chamber from the water inlet. As the water continuously flows in, the water flows vertically. At this time, the main mixer continuously sprays the colloid horizontally. The area where the water and the colloid collide is the spraying area, and the first mixing is completed at this time. If the mixing time is short, there will still be some parts that are not fully mixed. If the mixed liquid is directly exported at this time, the quality of the prepared latex will be poor. Therefore, by continuously setting the side body, the liquid that has completed the first mixing flows horizontally into the side mixing chamber. Part of the liquid is first sucked by the side mixer and then sprayed vertically. At this time, the liquid is moving horizontally, so a secondary collision is formed, achieving a more thorough mixing effect. And compared with the method of directly using a stirring rod for mixing, this solution uses multiple collisions, making the mixing effect better. Finally, the prepared liquid flows out vertically from the latex outlet. By using this device, the water and the colloid flow perpendicular to each other in the main body, so as to collide and achieve the purpose of rapid mixing. And after the water flows through the main body and the side body, it flows out from the latex outlet, without the need to control the time, and the operation is simple.

[0007] The present invention is further configured as: including a colloid feed pipe. The main mixer includes a stator and a rotor. The stator is fixedly arranged on the main body. There is an impact chamber inside the stator. A stator opening opposite to the colloid feed pipe is arranged below the stator. The rotor is arranged on the main shaft and rotates with the main shaft. The rotor is located inside the impact chamber. A plurality of rapids holes connecting the impact chamber and the main mixing chamber are annularly arranged on the outer periphery of the stator. One end of the colloid feed pipe is located in the main mixing chamber and is opposite to the stator opening, and the other end is located outside the main body and is used to receive the colloid. The side mixer has the same principle as the main mixer, so it will not be repeated here.

[0008] By adopting the above technical solution, the colloid enters the main mixing chamber from the colloid feed pipe, and the colloid enters the impact chamber through the stator opening under the action of inertia. At this time, the rotor rotates at a high speed inside the stator, so as to violently mix the water and the colloid in the impact chamber. Due to the existence of centrifugal force, the water and the colloid will move towards the inner wall of the stator. The rapids holes are arranged on the inner wall of the stator and connect the impact chamber and the main mixing chamber. Therefore, part of the water and the colloid will move horizontally towards the spraying area while mixing, and collide with the vertically moving water for the second time, improving the mixing effect. And the same is true for the side mixer. Just relying on the main mixer and the side mixer, four strong collisions occur, meeting the mixing of water and colloid to prepare latex, and the mixing degree of the latex can be as high as 98%.

[0009] The present invention is further configured as: a plurality of rotating blocks synchronously rotating with the rotor are arranged on the rotor, and the plurality of rotating blocks are respectively arranged on the upper side and the lower side of the rotor along the circumferential direction.

[0010] By adopting the above technical solution, the arrangement of the rotating blocks facilitates the throwing out of the water and the colloid.

[0011] The present invention is further configured such that: a fixing plate is disposed in the main mixing chamber, and a fixing rod is fixedly disposed in the main mixing chamber and the fixing rod is arranged in the same direction as the main shaft. The main shaft passes through the fixing plate and is rotationally engaged with the fixing plate. The stator is fixed below the fixing plate. The fixing plate and the fixing rod can also be disposed in the side mixing chamber to ensure the stable rotation of the side shaft. Since the principle is the same, no detailed description is given.

[0012] By adopting the above technical solution, the setting of the fixing plate and the fixing rod enables the main shaft not to shake strongly while rotating, ensuring the stable rotation of the main mixer.

[0013] The present invention is further configured such that: a plurality of communication ports for communicating the impact chamber with the main mixing chamber are provided on the fixing plate.

[0014] By adopting the above technical solution, the setting of the communication ports enables more water to be attracted into the impact chamber when the rotor rotates at a high speed.

[0015] The present invention is further configured to include a circulation pump, a circulation spray pipe, an outflow circulation pipe, and an inflow circulation pipe. The outflow circulation pipe is disposed between the circulation pump and the main mixing chamber and the height of the outflow circulation pipe is higher than the height of the side body. The inflow circulation pipe is disposed between the circulation pump and the main mixing chamber and the height of the inflow circulation pipe is lower than the height of the side body. The circulation spray pipe is disposed at the end of the inflow circulation pipe and the circulation spray pipe is arranged in a ring shape in the main mixing chamber. A plurality of spray nozzles are provided in the circulation spray pipe. The circulation pump is used to drive the liquid in the outflow circulation pipe into the inflow circulation pipe.

[0016] By adopting the above technical solution, during the flow of the liquid in the main mixing chamber, some of the liquid in the main mixing chamber above the side body may not enter the entire flow, thus accumulating at the top of the main mixing chamber, resulting in the adhesion of the colloid to the wall of the main mixing chamber and causing difficulties in cleaning. Therefore, under the action of the circulation pump, the liquid at the top of the main mixing chamber is continuously sucked from the outflow circulation pipe, and then the liquid is transported to a lower position through the inflow circulation pipe and sprayed horizontally along the center, colliding with the liquid moving vertically again. While reducing the possibility of colloid accumulation at the top of the main mixing chamber, the mixing efficiency is increased.

[0017] The present invention is further configured such that: an upper baffle plate and a lower baffle plate are disposed in the main mixing chamber. The upper baffle plate is fixed to the main mixing chamber and the height of the upper baffle plate gradually decreases along the direction close to the center of the main mixing chamber. The lower baffle plate is parallel to the upper baffle plate, and a spraying area is formed between the upper baffle plate and the lower baffle plate.

[0018] By adopting the above technical solution, the upper baffle and the lower baffle are arranged so that the colloid will not be completely carried away upward by the water flow during spraying. Instead, it first hits the wall of the main mixing chamber and then slides down along the lower baffle to the outside of the lower baffle, and then is driven upward by the water flow and passes through the spraying area for the second time, resulting in more thorough mixing.

[0019] The present invention is further configured as: a plurality of dynamic mixers for stirring are respectively arranged on the main shaft and the side shaft.

[0020] By adopting the above technical solution, the dynamic mixer is a conventional impeller for stirring on the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Such as Figures 1-5As shown in the figure, the present invention discloses an impact flow high-efficiency mixing device, which includes a main body 1, a main motor 11 and a main shaft 12. A main mixing chamber 14 is arranged inside the main body 1. The main motor 11 is arranged on the main body 1 and drives the main shaft 12 to rotate vertically in the main mixing chamber 14. It includes a side body 2, a side motor 21, a side shaft 22, a side mixer 23 and a main mixer 13. The main mixer 13 is arranged on the main body 1 and has a spraying area 15 for spraying the colloid horizontally. A water inlet for water to enter is arranged on the main body 1, and the water vertically passes through the spraying area 15. A side mixing chamber 24 is arranged inside the side body 2. The side body 2 is arranged horizontally on the main body 1, and the side mixing chamber 24 is communicated with the main mixing chamber 14. The side body 2 is located above the spraying area 15. The side motor 21 is arranged on the side body 2 and drives the side shaft 22 to rotate in the side mixing chamber 24. The side mixer 23 is arranged on the side shaft 22 and sucks the liquid in the side mixing chamber 24 and sprays it vertically. A latex outlet 25 for the liquid to flow out of the side mixing chamber 24 is arranged at the top of the side body 2. The rotational speed of the main motor 11 is 2900 revolutions per minute, and the power is 22 kw. The rotational speed of the side motor 21 is 2900 revolutions per minute, and the power is 15 kw. When preparing latex, water continuously flows into the main mixing chamber 14 from the water inlet. As the water continuously flows in, the water flows vertically. At this time, the main mixer 13 continuously sprays the colloid horizontally. The place where the water and the colloid collide is the spraying area 15. At this time, the first mixing is completed. If the mixing time is short, there will still be some parts that are not completely mixed. If the mixed liquid is directly exported at this time, the quality of the prepared latex is poor. Therefore, by continuously arranging the side body 2, the liquid that has completed the first mixing flows horizontally into the side mixing chamber 24. Part of the liquid is first sucked by the side mixer 23 and then sprayed vertically. At this time, the liquid is moving horizontally, so a secondary collision is formed, achieving a more thorough mixing effect. And compared with the method of directly using a stirring rod for mixing, this solution uses multiple impacts, making the mixing effect better. Finally, the prepared liquid flows out vertically from the latex outlet 25. By using this device, the water and the colloid flow perpendicular to each other in the main body 1, so as to collide and achieve the purpose of rapid mixing. And after the water flows through the main body 1 and the side body 2, it flows out from the latex outlet 25, without the need to control the time, and the operation is simple.

[0029] It includes a colloid feed pipe 3. The main mixer 13 includes a stator 131 and a rotor 132. The stator 131 is fixedly arranged on the main body 1 of the machine. There is an impact cavity 1311 inside the stator 131. Below the stator 131, there is a stator opening 1312 opposite to the colloid feed pipe 3. The rotor 132 is arranged on the main shaft 12 and rotates with the main shaft 12. The rotor 132 is located inside the impact cavity 1311. A plurality of rapids holes 1313 that connect the impact cavity 1311 with the main mixing cavity 14 are annularly arranged on the outer periphery of the stator 131. One end of the colloid feed pipe 3 is located inside the main mixing cavity 14 and is opposite to the stator opening 1312, and the other end is located outside the main body 1 of the machine and is used to receive the colloid. The side mixer 23 has the same principle as the main mixer 13, so it will not be repeated here. The colloid enters the main mixing cavity 14 from the colloid feed pipe 3, and the colloid enters the impact cavity 1311 through the stator opening 1312 under the action of inertia. At this time, the rotor 132 rotates at a high speed inside the stator 131, so as to violently mix the water and the colloid in the impact cavity 1311. Due to the existence of centrifugal force, the water and the colloid will move towards the inner wall of the stator 131. The rapids holes 1313 are arranged on the inner wall of the stator 131 and connect the impact cavity 1311 with the main mixing cavity 14. Therefore, part of the water and the colloid will move horizontally towards the spraying area 15 while being mixed, and collide with the water moving vertically for the second time, improving the mixing effect. The same is true for the side mixer 23. Just relying on the main mixer 13 and the side mixer 23, there are four strong collisions, which meet the mixing of water and colloid to prepare latex, and the mixing degree of the latex can be as high as 98%.

[0030] A plurality of rotating blocks 1321 that rotate synchronously with the rotor 132 are arranged on the rotor 132. The plurality of rotating blocks 1321 are respectively arranged on the upper side and the lower side of the rotor 132 along the circumferential direction. The arrangement of the rotating blocks 1321 facilitates the throwing out of water and colloid.

[0031] A fixing plate 5 is arranged inside the main mixing cavity 14. A fixing rod 51 is fixedly arranged inside the main mixing cavity 14 and the fixing rod 51 has the same arrangement direction as the main shaft 12. The main shaft 12 passes through the fixing plate 5 and is rotationally matched with the fixing plate 5. The stator 131 is fixed below the fixing plate 5. The fixing plate 5 and the fixing rod 51 can also be arranged in the side mixing cavity 24 to ensure the stable rotation of the side shaft 22. Since the principle is the same, it is not described in detail here. The arrangement of the fixing plate 5 and the fixing rod 51 makes the main shaft 12 not shake strongly while rotating, ensuring the stable rotation of the main mixer 13.

[0032] A plurality of communication ports 52 that connect the impact cavity 1311 with the main mixing cavity 14 are arranged on the fixing plate 5. The arrangement of the communication ports 52 enables more water to be attracted into the impact cavity 1311 when the rotor 132 rotates at a high speed.

[0033] It includes a circulation pump 4, a circulation nozzle 41, an outflow circulation pipe 42 and an inflow circulation pipe 43. The outflow circulation pipe 42 is arranged between the circulation pump 4 and the main mixing chamber 14, and the height of the outflow circulation pipe 42 is higher than the height of the side body 2. The inflow circulation pipe 43 is arranged between the circulation pump 4 and the main mixing chamber 14, and the height of the inflow circulation pipe 43 is lower than the height of the side body 2. The circulation nozzle 41 is arranged at the end of the inflow circulation pipe 43 and the circulation nozzle 41 is arranged around the main mixing chamber 14. A plurality of nozzles are arranged in the circulation nozzle 41. The circulation pump 4 is used to drive the liquid in the outflow circulation pipe 42 into the inflow circulation pipe 43. During the flow of the liquid in the main mixing chamber 14, part of the liquid in the main mixing chamber 14 above the side body 2 may not enter the whole flow, thus accumulating at the top of the main mixing chamber 14, resulting in the adhesion of the colloid to the wall of the main mixing chamber 14 and causing difficulties in cleaning. Therefore, under the action of the circulation pump 4, the liquid in the main mixing chamber 14 at the top is continuously sucked from the outflow circulation pipe 42, and then the liquid is transported to a lower position through the inflow circulation pipe 43 and sprayed horizontally along the center, colliding with the vertically moving liquid again. While reducing the possibility of the colloid accumulating at the top of the main mixing chamber 14, the mixing efficiency is increased.

[0034] An upper baffle plate 61 and a lower baffle plate 62 are arranged in the main mixing chamber 14. The upper baffle plate 61 is fixed to the main mixing chamber 14 and the height of the upper baffle plate 61 gradually decreases along the direction close to the center of the main mixing chamber 14. The lower baffle plate 62 is parallel to the upper baffle plate 61. A spraying area 15 is formed between the upper baffle plate 61 and the lower baffle plate 62. The arrangement of the upper baffle plate 61 and the lower baffle plate 62 enables the colloid not to be all taken away upwards by the water flow during spraying, but to first rush to the wall of the main mixing chamber 14 and then slide down along the lower baffle plate 62 outside the lower baffle plate 62, and then be driven by the water flow to move upwards and pass through the spraying area 15 for the second time, making the mixing more sufficient.

[0035] A plurality of dynamic mixers 7 for stirring are respectively arranged on the main shaft 12 and the side shaft 22. The dynamic mixer 7 is a conventional impeller for stirring on the market.

[0036] **Detailed implementation method**: When preparing latex, the high-concentration colloid processed by the emulsifying pump is transported to the main mixing chamber 14 through the colloid feed pipe 3. At the same time, water continuously flows into the main mixing chamber 14 from the water inlet. As the water continuously flows in, the water flows vertically, while the colloid enters the main mixing chamber 14 from the colloid feed pipe 3 and the colloid enters the impact chamber 1311 through the stator opening 1312. At this time, the rotor 132 rotates at a high speed within the stator 131, thereby violently mixing the water and the colloid in the impact chamber 1311. Due to the existence of centrifugal force, the water and the colloid move towards the inner wall of the stator 131. The torrent holes 1313 are arranged on the inner wall of the stator 131 and connect the impact chamber 1311 with the main mixing chamber 14. Therefore, part of the water and the colloid will move horizontally towards the spraying area 15 while mixing, and collide with the vertically moving water for the second time. After two collisions, part of the liquid enters the side body 2, and part accumulates at the top of the main mixing chamber 14. Therefore, under the action of the circulation pump 4, the liquid in the main mixing chamber 14 at the top is continuously sucked from the outflow circulation pipe 42, and then the liquid is transported to a lower position through the inflow circulation pipe 43 and sprayed horizontally towards the center, colliding with the vertically moving liquid for the third time. The liquid that enters the side body 2 also undergoes mixing in the side mixing chamber 24 and finally flows out from the latex outlet 25.
