Description

Technical Field

[0001] The present invention relates to the technical field of detergent preparation, and in particular to a mixing preparation method and a preparation system thereof suitable for an oily detergent. Background Art

[0002] In the production of oil-stain cleaners, the homogenization emulsification process is the core bridge connecting formula design and the final stable and efficient product. It uses powerful mechanical force to transform the immiscible oil and water phases into a uniform, stable, water-in-oil emulsion containing ultra-fine oil droplets. Cleaners that lack effective homogenization emulsification will have greatly reduced performance, unstable appearance, and unguaranteed shelf life. Therefore, the homogenization emulsification process is an essential step in the production of oil-stain cleaners.

[0003] Existing preparation systems have difficulty maintaining consistent homogenization and emulsification effects on raw materials at different heights. The emulsification effect of raw materials close to the homogenizer head is better, while the emulsification effect of raw materials far from the homogenizer head is relatively poor. To ensure the emulsification effect, the emulsification time needs to be extended and heating needs to be performed during the emulsification process. However, the temperature of the raw materials near the inner wall of the tank is often higher than that of the raw materials in the center of the tank, resulting in the raw material temperature in the center of the tank may not reach the ideal emulsification temperature. Therefore, when the existing preparation system directly extracts raw materials for emulsification treatment, it is difficult to ensure a stable emulsification effect. Summary of the Invention

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: See Figure 1 - Figure 8 A mixing and preparation system for oil-stain cleaning agents comprises a tank body 1, a feed pipe 2 mounted on the top of the tank body 1, and a homogenizing head 3 disposed inside the tank body 1. The homogenizing head 3 is conventional and primarily consists of a stator and a rotor. The homogenizing head continuously rotates at high speed under the continuous switching of high-frequency current. Macromolecular materials enter the narrow gap between the stator and rotor, experiencing hundreds of thousands of hydraulic shearing, centrifugal impact, extrusion and tearing effects per minute, resulting in instantaneous and uniform dispersion and emulsification. The materials are then sucked in from the end of the homogenizing head and, after multiple shearing and emulsification processes, dispersed into uniform products with special textures, such as lotions and creams. A partition 4 is installed inside the tank body 1, and the bottom end of the feed pipe 2 extends below the partition 4. A heating jacket 7 is installed outside the tank body 1. Also includes: A stirring mechanism is installed inside the tank body 1 and connected to the homogenizing head 3 for stirring the raw materials.

[0020] The stratified introduction mechanism is connected to the stirring mechanism and the homogenizing head 3 respectively, and is used for circulating and extracting the raw materials near the inner wall of the tank body 1. The stratified introduction mechanism includes a guide channel 13 opened in the stirring blade 11, a plurality of sealing rings 14 installed in the driving cylinder 8 and a trigger assembly for driving the sealing ring 14 to move; the guide channel 13 is connected to the inside of the driving cylinder 8, and the sealing ring 14 is attached to the inner wall of the driving cylinder 8 for closing the guide channel 13; a plurality of sealing rings 14 are arranged in sequence inside the driving cylinder 8 along the height direction of the driving cylinder 8; two sliding rods 15 are slidably connected to the inside of the sealing ring 14, and the top end of the sliding rod 15 is fixedly connected to the first limit block 16, and the bottom end of the sliding rod 15 is fixedly connected to the second limit block 17, and the first limit block 16 and the second limit block 17 are both fixedly connected to the inner wall of the driving cylinder 8; the outside of the sliding rod 15 is provided with a first spring 18, the top end of the first spring 18 is fixedly connected to the bottom of the first limit block 16, and the bottom end of the first spring 18 is fixedly connected to the sealing ring 14 The top of the sealing ring 14 is fixed; the trigger assembly includes a screw rod 20 rotatably connected to the inside of the driving cylinder 8, a lifting block 21 screwed to the outside of the screw rod 20 and a second motor 22 installed on the top of the tank body 1; the output end of the second motor 22 is fixed to the top of the screw rod 20, and the rotation speed of the screw rod 20 is different from the rotation speed of the driving cylinder 8; a plurality of guide rods 23 are fixed to the inside of the driving cylinder 8, and the lifting block 21 is also slidably sleeved on the outside of the guide rod 23; both ends of the lifting block 21 are provided with a slide groove 24, and the inside of the slide groove 24 is slidably connected to the driving block 25, one end of the driving block 25 slides and extends to the outside of the lifting block 21, and the top and bottom of one end of the driving block 25 are provided with an inclined groove 26; the other end of the driving block 25 is fixedly connected to a second spring 27, and the other end of the second spring 27 is fixedly connected to the inner wall of the slide groove 24, and the sum of the elastic forces of the two second springs 27 is greater than the sum of the elastic forces of the two first springs 18 in the same group; the bottom end of the screw rod 20 is fixedly connected to the top of the homogenizing head 3; By controlling the second motor 22 to drive the screw rod 20 to rotate clockwise, the homogenizing head 3 rotates accordingly, generating a suction force. When the screw rod 20 rotates, it drives the lifting block 21 to move upward along the outside of the guide rod 23. When the inclined groove 26 on the top of the lifting block 21 abuts against the bottom of the lowest sealing ring 14, the elastic force of the second spring 27 is greater than the elastic force of the first spring 18. Therefore, the driving block 25 will not move toward the inside of the slide groove 24, but drive the sealing ring 14 to move upward. The first spring 18 is compressed accordingly, so that the guide channel 13 in the lowest stirring blade 11 is connected to the inside of the driving cylinder 8. The raw materials inside the tank body 1 enter the inside of the driving cylinder 8 through the guide channel 13 of the lowest layer, and after being sheared by the homogenizing head 3, they are discharged back to the inside of the tank body 1 and move on the sealing ring 14 to the position aligned with the first When the bottom of the limit block 16 abuts, the sealing ring 14 stops moving upward, and the driving block 25 moves toward the inside of the slide groove 24. The second spring 27 is compressed. After the driving block 25 completely enters the interior of the lifting block 21, after the lifting block 21 passes over the current sealing ring 14, the inclined groove 26 on the top of the driving block 25 begins to abut against the bottom of the upper sealing ring 14, and drives the upper sealing ring 14 to move upward, so that the guide channel 13 of the second-to-last layer is connected with the interior of the driving cylinder 8, thereby drawing the raw materials at the height of the guide channel 13 of the second-to-last layer into the interior of the driving cylinder 8, and after being sheared by the homogenizing head 3, it is discharged back into the interior of the tank body 1, and in this way, raw materials of different heights are extracted and sheared from bottom to top, thereby avoiding the problem of poor homogenization effect of raw materials far away from the homogenizing head 3; After the lifting block 21 passes over the current sealing ring 14, the rebound force of the first spring 18 drives the sealing ring 14 to move downward and reset, thereby resealing the guide channel 13; When the lifting block 21 drives the uppermost sealing ring 14 to abut against the bottom of the uppermost first limit block 16, the second motor 22 is controlled to drive the screw rod 20 to rotate counterclockwise. When the screw rod 20 rotates counterclockwise, the homogenizing head 3 also rotates accordingly, but no suction force is generated. When the screw rod 20 rotates counterclockwise, it drives the lifting block 21 to move downward, and the inclined groove 26 at the bottom of the driving block 25 abuts against the top of the sealing ring 14. Since each sealing ring 14 is restricted by the second limit block 17 below it, the driving block 25 directly enters the interior of the lifting block 21. Therefore, the lifting block 21 directly passes over each sealing ring 14, and in the process of the lifting block 21 moving downward and the homogenizing head 3 not generating suction force, the stirring blade 11 stirs the raw materials inside the tank body 1, so that the raw materials after homogenization are re-mixed and re-layered for re-homogenization, thereby improving the uniformity of the raw material emulsification.

[0021] The stratified defoaming mechanism is connected to the stirring mechanism and the stratified introduction mechanism respectively, and is used to introduce the defoaming agent into the emulsified raw materials in layers. The stratified defoaming mechanism includes a guide tube 28 installed inside the stirring blade 11 and a metering cylinder 29 installed on the top of the stirring blade 11. An air pipe is installed on the metering cylinder 29, and an electromagnetic valve is also installed on the air pipe. When the defoaming agent in the metering cylinder 29 is discharged, the electromagnetic valve is opened first, and external air can enter the metering cylinder 29, so that the defoaming agent in the metering cylinder 29 can be discharged smoothly; one end of the guide tube 28 is connected to the two metering cylinders above and below it. The first solenoid valve 30 is installed on the guide tube 28, and the other end of the guide tube 28 is connected to the guide channel 13; the second solenoid valve 31 is installed on the metering cylinder 29, and a feeding chamber 32 is fixedly connected to the interior of the partition 4. The feeding chamber 32 is sleeved on the outside of the driving cylinder 8, and the bottom of the feeding chamber 32 is rotatably connected to a sealing ring 33; an injection tube 34 is installed on the top of the feeding chamber 32, and the other end of the injection tube 34 extends to the outside of the tank body 1; wherein, the top of the metering cylinder 29 located below the partition 4 is penetrated by the sealing ring 33, and when defoaming, the homogenizing head 3 does not generate suction force; After emulsification is completed, each first solenoid valve 30 is controlled to be closed, and each second solenoid valve 31 is opened, and the defoaming agent is injected into the feeding chamber 32 through the injection tube 34, and the defoaming agent in the feeding chamber 32 then enters the metering cylinder 29. Then, each first solenoid valve 30 is controlled to be opened, and each second solenoid valve 31 is controlled to be closed, and the defoaming agent in the metering cylinder 29 enters the guide channel 13. At the same time, the second motor 22 is controlled to drive the driving cylinder 8 to rotate, and each stirring blade 11 rotates accordingly. In this process, the defoaming agent in the guide channel 13 is thrown into the raw material by centrifugal force. By throwing the defoaming agent into the emulsified raw material in a dispersed manner at different heights, the speed and sufficiency of the raw material defoaming are effectively improved. When the driving cylinder 8 rotates, it drives each metering cylinder 29 to rotate with the driving cylinder 8 as the center, and synchronously drives the sealing ring 33 to rotate.

[0022] A discharge pipe 5 is installed at the bottom of the tank body 1, and a valve 6 is installed on the discharge pipe 5; By opening the valve 6 , the product after emulsification and defoaming in the tank body 1 can be discharged.

[0023] A plurality of scraping strips 19 are fixedly connected to the outer wall of the driving cylinder 8 via a connecting rod, and the outer wall of the scraping strips 19 abuts against the inner wall of the tank body 1; When the driving cylinder 8 rotates, it drives the scraper 19 to rotate along the inner wall of the tank body 1 to prevent the raw materials from sticking to the inner wall of the tank body 1 for a long time and causing the problem of paste.

[0024] A mixing preparation method for an oil-stain cleaning agent adopts the above-mentioned mixing preparation system for an oil-stain cleaning agent, comprising the following steps: injecting product production raw materials into the interior of the tank body 1 through the feed pipe 2, and starting the heating sleeve 7 to control the temperature and heat the raw materials inside the tank body 1, and controlling the second motor 22 to drive the screw rod 20 to rotate clockwise, and the homogenizing head 3 rotates accordingly to generate suction force. When the screw rod 20 rotates, it drives the lifting block 21 to move upward along the outside of the guide rod 23. When the inclined groove 26 at the top of the lifting block 21 abuts against the bottom of the lowest sealing ring 14, the elastic force of the second spring 27 is greater than the elastic force of the first spring 18, so the driving block 25 will not move toward the inside of the slide groove 24, but drive the sealing ring 14 to move upward. The first spring 18 is then compressed, so that the guide channel 13 in the lowest stirring blade 11 is connected to the inside of the driving cylinder 8, and the raw materials inside the tank body 1 enter the inside of the driving cylinder 8 through the guide channel 13 of the lowest layer, and are sheared by the homogenizing head 3 and discharged back into the tank body 1. When the sealing ring 14 moves up and abuts against the bottom of the first limit block 16, the sealing ring 14 stops moving upward, and the driving block 25 moves toward the inside of the slide groove 24. The second spring 27 is compressed, and after the driving block 25 completely enters the inside of the lifting block 21, after the lifting block 21 passes over the current sealing ring 14, the inclined groove 26 on the top of the driving block 25 begins to abut against the bottom of the upper sealing ring 14, and drives the upper sealing ring 14 to move upward, so that the guide channel 13 of the second to last layer is connected to the inside of the driving cylinder 8. The raw materials at the height of the penultimate layer of the guide channel 13 are drawn into the driving cylinder 8, and after being sheared by the homogenizing head 3, they are discharged back into the tank body 1. In this cycle, raw materials at different heights are extracted and sheared from bottom to top, avoiding the problem of poor homogenization effect of raw materials far away from the homogenizing head 3. When extracting raw materials in layers, the raw materials near the heating position of the inner wall of the tank body 1 are first extracted for homogenization and shearing, avoiding the problem of large temperature differences of raw materials inside the tank body 1. When the screw rod 20 rotates counterclockwise, it drives the lifting block 21 to move downward, and the inclined groove 26 at the bottom of the driving block 25 abuts against the top of the sealing ring 14. Since each sealing ring 14 is restricted by the second limit block 17 below it, the driving block 25 directly enters the lifting block 21. This lifting block 21 directly passes over each sealing ring 14, and in the process that the lifting block 21 moves down and the homogenizing head 3 does not generate suction force, the stirring blade 11 stirs the raw materials inside the tank body 1, so that the raw materials after homogenization are remixed and re-stratified for re-homogenization, thereby improving the uniformity of raw material emulsification. After the emulsification is completed, the first solenoid valves 30 are controlled to be closed, and the second solenoid valves 31 are controlled to be opened, and the defoaming agent is injected into the feeding chamber 32 through the injection pipe 34. The defoaming agent in the feeding chamber 32 then enters the inside of the metering cylinder 29, and then the first solenoid valves 30 are controlled to be opened, and the second solenoid valves 31 are controlled to be closed, and the defoaming agent in the metering cylinder 29 enters the inside of the guide channel 13. At the same time, the second motor 22 is controlled to drive the driving cylinder 8 to rotate.Each stirring blade 11 rotates accordingly. In this process, the defoaming agent in the guide channel 13 is thrown into the raw material by centrifugal force. By throwing the defoaming agent into the emulsified raw material in a dispersed manner at different heights, the speed and sufficiency of defoaming of the raw material are effectively improved.
