Technical Field

[0002] The multi-enzyme cleaning solution compound enzyme preparation mixing equipment adopts a double-jacketed stirring chamber with variable frequency speed-regulating blades, which can precisely control the temperature and stirring rate. It is suitable for compounding processes of various enzyme preparations such as protease and lipase, effectively breaking down enzyme clusters and performing low-shear stirring. The equipment, together with the feeding device, can realize automated feeding, enabling efficient, stable, and large-scale production of multi-enzyme cleaning solution compound enzyme preparations.
[0003] In existing multi-enzyme cleaning solution compound enzyme preparation mixing equipment, the speed of low-shear stirring blades is generally achieved by using a motor and a reducer to achieve speed regulation stirring when preparing multi-enzyme cleaning solution compound enzyme preparations.

[0014] The mixing process of multi-enzyme washing solution and compound enzyme preparation includes the following steps: Step 1: Inject materials into the mixing tank and control the temperature of the mixing tank by introducing liquid into the jacket; Step 2: Start the motor to drive the mixing mechanism.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see the appendix Figure 1 -Appendix Figure 9This invention provides a mixing device for a multi-enzyme cleaning solution and a compound enzyme preparation, including a mixing tank 1. A jacket 2 is formed on the outer wall of the mixing tank 1, allowing liquid to pass through for temperature control. A tank cover 3 is provided on the top of the jacket 2, maintaining the seal inside the mixing tank 1 and providing an installation position. A mixing mechanism 4 is provided inside the mixing tank 1 to improve the mixing effect of the liquid inside. An defoaming mechanism 5 is also provided inside the mixing tank 1 to eliminate foam generated during stirring. A vacuum mechanism 6 is provided on the top of the tank cover 3 to provide a negative pressure stirring environment. A speed reducer 7 is fixedly connected to the outside of the vacuum mechanism 6. A motor 8 is fixedly connected to the top of the reducer 7. The output shaft of the motor 8 is fixedly connected to the input shaft of the reducer 7. The motor 8 is used to provide power for stirring and mixing. A discharge valve 15 is fixedly connected to the top of the mixing tank 1. A liquid inlet 13 is fixedly connected to the bottom of the mixing tank 1. A liquid outlet 14 is fixedly connected to the top of the mixing tank 1. A stabilizing sensor 12 is fixedly connected to the top of the mixing tank 1. Multiple locking ribs 10 are fixedly connected to the top of the tank cover 3. Multiple buckles 11 are fixedly connected to the top of the mixing tank 1. The buckles 11 and locking ribs 10 are locked together. A mounting bracket 16 is fixedly connected to the outside of the mixing tank 1. A liquid injection pipe 9 is fixedly connected to the top of the tank cover 3.
[0020] The mixing mechanism 4 includes a rotating shaft 401, which can rotate under the drive of a motor 8. The top of the rotating shaft 401 is rotatably connected to the top of the tank cover 3. Two augers 402 are fixedly connected to the outside of the rotating shaft 401, with the upper and lower augers 402 having opposite spiral directions. Four fixed brackets 403 are fixedly connected to the inner wall of the mixing tank 1, and two sleeves 404 are fixedly connected between the four fixed brackets 403. The fixed brackets 403 can install the sleeves 404, and through the cooperation of the augers 402 and the sleeves 404, the liquid at the top of the mixing tank 1 can be flowed towards the middle by the upper auger 402, while the liquid at the bottom of the mixing tank 1 can be flowed towards the middle by the lower auger 402. The two augers 402 are respectively set inside the two sleeves 404. A low-shear stirring rack 405 is fixedly connected to the bottom of the rotating shaft 401. The stirring rack 405 can agitate the liquid. The output end of the reducer 7 is fixedly connected to the top of the rotating shaft 401. When preparing the multi-enzyme washing solution compound enzyme preparation, the motor 8 is started. The speed of the motor 8 is reduced by the reducer 7 and drives the rotating shaft 401 to rotate. After the rotating shaft 401 rotates, it can drive the auger 402 to rotate. The rotation of the auger 402 can cooperate with the sleeve 404 to make the liquid in the upper part of the mixing tank 1 be drawn to the middle of the mixing tank 1 through the rotation of the upper auger 402, while the liquid in the lower part of the mixing tank 1 is drawn to the middle through the lower auger 402. With the rotation of the low-shear stirring rack 405, the density difference and concentration difference of the upper and lower layers of materials in the tank can be eliminated, avoiding powder sedimentation and liquid floating. The mixing is faster and more uniform under low-shear conditions, while maximizing the retention of enzyme activity.
[0021] The defoaming mechanism 5 includes a mounting sleeve 501, which provides an installation position. The interior of the mounting sleeve 501 is slidably connected to the exterior of the rotating shaft 401. A sliding sleeve 502 is slidably connected to the top of the exterior of the rotating shaft 401, providing the installation position. Both the sliding sleeve 502 and the inner wall of the mounting sleeve 501 are provided with toothed grooves 503. Multiple defoaming rods 504 are fixedly connected to the exterior of the mounting sleeve 501. The lower part of the defoaming rods 504 is serrated, which can break up the foam while rotating. The multiple defoaming rods 504 are located away from the mounting sleeve 501. A float ring 505 is fixedly connected to one end of the sliding sleeve 502. The float ring 505 can float on the liquid surface of the mixing tank 1. Multiple scraper blades 506 are fixedly connected to the outside of the sliding sleeve 502. The scraper blades 506 can scrape off the material inside the tank cover 3 when rotating. A toothed ring 507 is fixedly connected to the top of the outside of the rotating shaft 401. The toothed ring 507 meshes with the toothed groove 503. The toothed ring 507 can rotate with the rotating shaft 401, thereby cooperating with the toothed groove 503 to drive the mounting sleeve 501 and the sliding sleeve 502 to rotate. The outside of the rotating shaft 401 A blocking ring 508 is fixedly connected. When the rotating shaft 401 rotates, it drives the gear ring 507 to rotate. Since the gear ring 507 meshes with the mounting sleeve 501 and the toothed groove 503 inside the toothed groove 503, the rotation of the rotating shaft 401 drives the mounting sleeve 501 and the sliding sleeve 502 to rotate, and also drives the defoaming rod 504 and the skimmer 506 to rotate. When liquid is injected into the temporal part of the mixing tank 1, the floating ring 505 causes the defoaming rod 504 and the mounting sleeve 501 to float upwards, thus enabling... The toothed structure below the defoaming rod 504 breaks up the foam while rotating, thus eliminating the foam. At the same time, the sliding sleeve 502 moves upward with the liquid surface under the push of the mounting sleeve 501. When the scraper 506 contacts the top of the mixing tank 1, it means that the distance between the liquid surface and the inner wall of the tank cover 3 is short. Therefore, when the foam breaks, the material will splash onto the inner wall of the tank cover 3. At this time, when the sliding sleeve 502 rotates with the rotation shaft 401, it will scrape the material off the inner wall of the tank cover 3, further avoiding material waste.
[0022] The suction mechanism 6 includes an arc-shaped air cylinder 601, which provides the installation position and the foundation for suction. The arc-shaped air cylinder 601 is externally fixedly connected to the top of the can lid 3. An arc-shaped spring 602 is provided inside the arc-shaped air cylinder 601. A limit block 603 is slidably connected inside the arc-shaped air cylinder 601, and the limit block 603 has a limiting function. An arc-shaped rod 604 is fixedly connected to the end of the limit block 603 away from the arc-shaped spring 602, and the arc-shaped rod 604 has a connecting function. An installation head 605 is fixedly connected to the end of the arc-shaped rod 604 away from the limit block 603, and the installation head 605 provides the installation position. A fixing rod 606 is rotatably connected inside the installation head 605. A torsion spring 607 is sleeved on the outside of the fixing rod 606. The external fixed connection of 06 is a rotating frame 608. The fixed rod 606 can install the rotating frame 608. The torsion spring 607 can use its own elastic force to drive the rotating frame 608 to rotate and reset. The external fixed connection of the rotating frame 608 is a driving column 609. One end of the arc-shaped air cylinder 601 is externally fixedly connected to an exhaust valve 610, which can perform air intake and exhaust. The other end of the arc-shaped air cylinder 601 is fixedly connected to a three-way valve 611, which can not only perform air intake but also exhaust, and the air intake and exhaust channels are not the same. The top of the can lid 3 is fixedly connected to a blocking inclined rod 612. The end of the three-way valve 611 away from the arc-shaped air cylinder 601 is fixedly connected to a suction connection pipe 613. As an air intake channel, a breather valve 614 is fixedly connected to the bottom of the air intake connection pipe 613. The breather valve 614 only allows air and not liquid. The bottom of the breather valve 614 is fixedly connected to the top of the can lid 3. A drive rod 615 is fixedly connected to the external output end of the reducer 7. The drive rod 615 can drive the drive column 609 to move in the direction of the air intake connection pipe 613. The blocking inclined rod 612 is inclined and can squeeze the drive column 609, causing the drive column 609 to tilt during the movement. This allows the drive column 609 to move away from the range of the drive rod 615, so that under the reaction force of the arc spring 602, the drive column 609 can move in the opposite direction. A pressure regulating valve 616 is fixedly connected to the top of the can lid 3 for pressure regulation. Valve 616 draws air from the outside, maintaining a slight negative pressure inside the mixing tank 1. One end of the arc-shaped spring 602 is fixedly connected to the inside of the arc-shaped air cylinder 601, and the other end is fixedly connected to the end of the limiting block 603 away from the arc-shaped rod 604. One end of the torsion spring 607 is fixedly connected to the inside of the mounting head 605, and the other end is fixedly connected to the outside of the fixing rod 606. The reducer 7 is fixedly connected to the outside of the arc-shaped air cylinder 601. The outside of the arc-shaped rod 604 passes through the end of the arc-shaped air cylinder 601 away from the three-way valve 611. When the output end of the reducer 7 rotates, it can drive the driving rod 615 to rotate, thereby driving the driving column 609 to rotate away from the limiting block 603.This causes the rotating frame 608, fixed rod 606, arc rod 604, and limiting block 603 to move away from the arc spring 602. At this time, the gas in the space inside the arc air cylinder 601 at the position of the exhaust valve 610 will be discharged through the exhaust valve 610. Meanwhile, the space in the direction of the three-way valve 611 begins to draw air as the limiting block 603 moves. This allows the air inside the mixing tank 1 to be drawn away through the three-way valve 611, the air extraction connecting pipe 613, and the breather valve 614, creating a negative pressure inside the mixing tank 1. As a result, the surface tension of the foam decreases, making it easier to break, thus assisting in eliminating foam. At the same time, it isolates air, reduces enzyme activity oxidation, and improves enzyme activity retention. When the rotating column 609 moves to the position of the blocking inclined rod 612, the blocking inclined rod... 612 is designed with an incline, so the driving column 609 receives rotational force from the reducer 7. When the driving column 609 rotates away from the range of the driving rod 615, it can move the limiting block 603 towards the three-way valve 611 under the tension of the arc spring 602, and draw in air using the exhaust valve 610. This avoids the situation where the limiting block 603 cannot move due to negative pressure. At the same time, the gas in the space near the three-way valve 611 in the arc-shaped air cylinder 601 can be discharged to the outside through the air valve outside the three-way valve 611. When the arc rod 604 retracts, the fixed rod 606 rotates under the reaction force of the torsion spring 607, which in turn drives the rotating frame 608 and the driving column 609 to reset, thus facilitating the next cycle of air intake 1.
[0023] The mixing process of multi-enzyme washing solution and compound enzyme preparation includes the following steps: Step 1: Inject materials into the mixing tank 1 and control the temperature of the mixing tank 1 by introducing liquid into the jacket 2; Step 2: Start the motor 8 to drive the mixing mechanism 4 to run. The mixing mechanism 4 enables the liquid inside the mixing tank 1 to flow from the bottom and top to the middle, eliminating the density and concentration differences between the upper and lower layers of material in the tank. Step 3: During the stirring process, the defoaming mechanism 5 rises with the liquid level and rotates with the mixing mechanism 4 to eliminate foam and avoid material loss; Step 4: When the motor 8 is running, the air pressure inside the mixing tank 1 is extracted, thereby reducing the air pressure inside the mixing tank 1. This creates a negative pressure inside the mixing tank 1, isolates the air, reduces enzyme activity and oxidation, and reduces the surface tension of the foam, thus assisting in the foam's collapse.
[0024] Working principle: When preparing the multi-enzyme cleaning solution compound enzyme preparation, the motor 8 is started. The speed of the motor 8 is reduced by the reducer 7 and drives the rotating shaft 401 to rotate. The rotation of the rotating shaft 401 drives the auger 402 to rotate. The rotation of the auger 402, together with the sleeve 404, allows the liquid in the upper part of the mixing tank 1 to be drawn towards the middle of the mixing tank 1 through the rotation of the upper auger 402, while the liquid in the lower part of the mixing tank 1 is drawn towards the middle through the lower auger 402. With the rotation of the low-shear stirring rack 405, the density and concentration difference between the upper and lower layers of materials in the tank can be eliminated, avoiding powder sedimentation and liquid floating. Under low-shear conditions, faster and more uniform mixing is achieved, while maximizing the retention of enzyme activity. When the rotating shaft 401 rotates, it drives the gear ring 507 to rotate. Since the gear ring 507 meshes with the mounting sleeve 501 and the toothed groove 503 inside the toothed groove 503, the rotation of the rotating shaft 401 drives the mounting sleeve 501 and the sliding sleeve 502 to rotate, and also drives the defoaming rod 504 and the skimmer 506 to rotate. When liquid is injected into the temporal part of the mixing tank 1, the floating ring 505 causes the defoaming rod 504 and the mounting sleeve 501 to float upwards, thus enabling the defoaming rod 504 to... The toothed structure below breaks up the foam while rotating, thus eliminating the foam. At the same time, the sliding sleeve 502 moves upward with the liquid surface under the push of the mounting sleeve 501. When the scraper 506 contacts the top of the mixing tank 1, it means that the distance between the liquid surface and the inner wall of the tank cover 3 is short. Therefore, when the foam breaks, the material will splash onto the inner wall of the tank cover 3. At this time, when the sliding sleeve 502 rotates with the rotation shaft 401, it will scrape the material off the inner wall of the tank cover 3, further avoiding material waste. When the output end of the reducer 7 rotates, it drives the driving rod 615 to rotate, which in turn drives the driving column 609 to rotate away from the limiting block 603. This, in turn, drives the rotating frame 608, the fixed rod 606, the arc-shaped rod 604, and the limiting block 603 to move away from the arc-shaped spring 602. At this time, the gas in the space inside the arc-shaped air cylinder 601 at the position of the exhaust valve 610 will be discharged through the exhaust valve 610. Meanwhile, the space in the direction of the three-way valve 611 begins to draw air as the limiting block 603 moves. This allows the air inside the mixing tank 1 to be drawn away through the three-way valve 611, the air extraction connecting pipe 613, and the breather valve 614, creating a negative pressure inside the mixing tank 1. As a result, the surface tension of the foam decreases, making it easier to break, thus assisting in eliminating foam. At the same time, it isolates air, reduces enzyme activity oxidation, and improves enzyme activity retention rate. When the drive column 609 moves to the position of the blocking bar 612, the drive column 609 is subjected to rotational force towards the reducer 7 because the blocking bar 612 is inclined. When the drive column 609 rotates away from the range of the drive rod 615, it can drive the limit block 603 to move towards the three-way valve 611 under the tension of the arc spring 602, and use the exhaust valve 610 to draw in air, thereby avoiding the situation where the limit block 603 cannot move due to negative pressure. At the same time, the gas in the space near the three-way valve 611 in the arc air cylinder 601 can be discharged to the outside through the air valve outside the three-way valve 611. When the arc rod 604 retracts, the fixed rod 606 rotates under the reaction force of the torsion spring 607, which can then drive the rotating frame 608 and the drive column 609 to reset, thereby facilitating the air intake of the next cycle.
