Description

Technical Field

[0001] The present invention relates to the technical field of mixing equipment, and in particular to a homogeneous mixing device and method for producing detergent. Background Art

[0002] Detergents are products specially formulated for cleaning through a cleaning process. They can be divided into various forms such as powder, block, paste, slurry and liquid according to their appearance. In the production process of liquid detergents, the raw materials are homogenized and mixed, and the materials are sequentially introduced into a homogenizing mixing device for stirring and homogenization to obtain a homogenous mixed liquid. There is no need to control the temperature during the stirring process. When producing detergents using deionized water as a solvent, linear alkylbenzene sulfonic acid, alkylolamide and sodium hydroxide as base materials, and AES and AEO9 as active agents, the production process is as follows: first, deionized water is introduced into a homogenizing mixing device, sodium hydroxide is added, and linear alkylbenzene sulfonic acid is slowly added after it is dissolved. The mixing device mixes and homogenizes the material liquid, and the surfactants AES and AEO9 are added at a temperature of 40-50°C to obtain a mixed liquid after dissolution.

[0003] During the dissolution of sodium hydroxide, a large amount of heat is released, and the released heat increases the temperature of the deionized water. Then, linear alkylbenzene sulfonic acid is added to the homogeneous mixing device. Under the stirring of the homogeneous mixing device, sodium hydroxide and linear alkylbenzene sulfonic acid undergo acid-base neutralization reaction, releasing heat again. The released heat further increases the temperature of the ionized water, making the temperature of the ionized water exceed 50°C. After the raw materials are stirred for a period of time in the homogeneous mixing device, the substances in the liquid are completely reacted, and the reaction process continues to release heat. In order to avoid burns to the operators, the shell of the homogeneous mixing device is made of anti-corrosion and heat-insulating materials. The surfactant AES is easily hydrolyzed at a temperature above 50°C, thereby reducing the quality of the detergent. In order to avoid hydrolysis of the surfactant AES, the mixing time of the liquid is extended and the temperature of the liquid is reduced. However, extending the stirring time of the liquid will reduce the homogeneous mixing speed of the liquid, and the detergent cannot be produced quickly. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that the mixing time of the feed liquid is prolonged and the homogeneous mixing speed of the feed liquid is reduced, and a homogeneous mixing device for producing detergent is proposed.

[0016] S1: The raw materials are introduced into the mixing chamber through the feed pipe, and the controller controls the stirring mechanism to be powered on and started. After the stirring mechanism is started, the material liquid in the mixing chamber is stirred. The material liquid in the mixing chamber rotates under the stirring of the stirring mechanism, and the material liquid in the mixing chamber drives the mixing element to rotate.

The rotating shaft 421 is used to mount the stirring teeth 422. The other end of the rotating shaft 421 is fixedly connected to the stirring teeth 422. The stirring teeth 422 are used to mix the liquid in the mixing chamber.

[0037] The liquid feeding mechanism 6 includes a support plate 61, a liquid storage tank 62, a first valve 63 and a first conduit 64. The support plate 61 is fixedly connected to the upper end of the shell 1. The support plate 61 is used to support and fix the liquid storage tank 62. The liquid storage tank 62 is fixedly connected to the support plate 61. The liquid storage tank 62 is used to store cooling water. The liquid storage tank 62 is connected to the liquid circulation mechanism 8. One end of the first conduit 64 is connected to the bottom end of the liquid storage tank 62. The first conduit 64 is used to guide the cooling water in the liquid storage tank 62 into the open frame 3. The other end of the first conduit 64 is connected to the open frame 3. The first valve 63 is connected to the first conduit 64. When the first valve 63 is opened, the cooling water in the liquid storage tank 62 enters the open frame 3 through the first conduit 64 and contacts the heat-conducting rod 41 in the open frame 3, thereby cooling the heat-conducting rod 41.

[0038] The liquid circulation mechanism 8 includes a collection box 81, a pump 82, a second conduit 83, a third conduit 84 and a flow meter 85. The collection box 81 is fixedly connected to the housing 1 and is connected to the drain pipe 7. The pump 82 is fixedly connected to the upper end of the collection box 81. One end of the second conduit 83 is connected to the inlet of the pump 82. The other end of the second conduit 83 extends to the inner bottom of the collection box 81. One end of the third conduit 84 is connected to the outlet of the pump 82. The third conduit 84 is a metal pipe. When the cooling water flows in the third conduit 84, the third conduit 84 releases heat, thereby reducing the temperature of the cooling water in the third conduit 84. The other end of the conduit 84 is connected to the liquid storage tank 62, and the flow meter 85 is connected to the third conduit 84. The controller controls the pump 82 to be powered on and started. After the pump 82 is started, the cooling water in the collection tank 81 is pumped out through the second conduit 83. The pumped cooling water is introduced into the liquid storage tank 62 through the third conduit 84. When the cooling water flows in the third conduit 84, the third conduit 84 releases heat, thereby reducing the temperature of the cooling water in the third conduit 84 and recycling the cooling water. The flow meter 85 measures the cooling water passing through the third conduit 84. When the amount of cooling water passing through reaches a set value, the controller controls the pump 82 to stop working.

[0039] Working process: the raw materials are introduced into the mixing chamber through the feed pipe, and the controller controls the stirring mechanism 5 to be powered on and started. After the stirring mechanism 5 is started, the material liquid in the mixing chamber is stirred, and the material liquid in the mixing chamber rotates under the stirring of the stirring mechanism 5. The material liquid in the mixing chamber drives the mixing element 42 to rotate, and the rotating mixing element 42 mixes the liquid, thereby improving the mixing effect of the stirring mechanism 5. During the mixing process, the substances in the material liquid react with each other. During the reaction, the temperature of the material liquid continues to rise. The thermometer detects the temperature of the material liquid. The heat-conducting rod 41 contacts the material liquid, and the heat-conducting rod 41 conducts heat from the material liquid to reduce the temperature of the material liquid. At the same time, the controller controls the first valve 63 to open, and the cooling water in the liquid storage tank 62 enters the open rack 3 through the first conduit 64, contacts the heat-conducting rod 41 in the open rack 3, and exchanges heat with the heat-conducting rod 41 to cool down, thereby accelerating the cooling speed of the material liquid in the mixing chamber. The controller controls the second valve to open, and the cold water heated by heat exchange is discharged through the drain pipe 7. The discharged cold water The liquid is gathered in the collection box 81 and the heat transfer rod 41 is cooled by heat exchange with cooling water to ensure that after the stirring set time, the temperature of the liquid in the mixing chamber will not cause the surfactant to hydrolyze. There is no need to lower the temperature of the liquid in the mixing chamber by extending the stirring time of the stirring mechanism 5, thereby accelerating the homogeneous mixing speed of the liquid. After the surfactant is added, the stirring mechanism 5 continues to stir, and the controller controls the first valve 63 to close. The controller controls the pump 82 to be powered on and started. After the pump 82 is started, the cooling water in the collection box 81 is pumped out through the second conduit 83, and the pumped cooling water is introduced into the liquid storage tank 62 through the third conduit 84. When the cooling water flows in the third conduit 84, the third conduit 84 releases heat, thereby reducing the temperature of the cooling water in the third conduit 84, and the cooling water is recycled. The flow meter 85 measures the cooling water passing through the third conduit 84. When the amount of cooling water passing through reaches the set value, the controller controls the pump 82 to stop working. After the mixing of the liquid and the material is completed, the cooling water is discharged from the discharge pipe.

[0040] The present invention also provides a homogeneous mixing method for producing detergent, comprising the following steps:

[0041] S1: The raw materials are introduced into the mixing chamber through the feed pipe, and the controller controls the stirring mechanism 5 to be powered on and started. After the stirring mechanism 5 is started, the material liquid in the mixing chamber is stirred. The material liquid in the mixing chamber rotates under the stirring of the stirring mechanism 5, and the material liquid in the mixing chamber drives the mixing element 42 to rotate. The rotating mixing element 42 mixes the liquid, thereby improving the mixing effect of the stirring mechanism 5. During the mixing process, the substances in the material liquid react with each other. During the reaction, the temperature of the material liquid continues to rise. The temperature of the material liquid is detected by the thermometer. The heat conducting rod 41 contacts the material liquid and conducts heat from the material liquid to reduce the temperature of the material liquid.

[0042] S2: At the same time, the controller controls the first valve 63 to open, and the cooling water in the liquid storage tank 62 enters the open rack 3 through the first conduit 64, contacts the heat-conducting rod 41 in the open rack 3, exchanges heat and cools the heat-conducting rod 41, thereby accelerating the cooling rate of the liquid in the mixing chamber. The controller controls the second valve to open, and the cold water heated by heat exchange is discharged through the drain pipe 7. The discharged cold water is collected in the collection box 81, and the heat-conducting rod 41 is cooled by the cooling water. This ensures that after the set stirring time, the temperature of the liquid in the mixing chamber does not cause the surfactant to hydrolyze, and there is no need to extend the stirring time of the stirring mechanism 5 to reduce the temperature of the liquid in the mixing chamber, thereby accelerating the homogeneous mixing speed of the liquid.

[0043] S3: After the surfactant is added, the stirring mechanism 5 continues stirring, the controller controls the first valve 63 to close, and the controller controls the pump 82 to be powered on and started. After the pump 82 is started, the cooling water in the collection box 81 is pumped out through the second conduit 83, and the pumped cooling water is introduced into the liquid storage tank 62 through the third conduit 84. When the cooling water flows in the third conduit 84, the third conduit 84 releases heat, thereby reducing the temperature of the cooling water in the third conduit 84, and the cooling water is recycled. The flow meter 85 measures the cooling water passing through the third conduit 84. When the amount of cooling water passing through reaches the set value, the controller controls the pump 82 to stop working. After the mixing of the material and liquid is completed, the cooling water is discharged from the discharge pipe;

[0044] S4: The controller starts the electric telescopic rod 93. After the electric telescopic rod 93 starts, it drives the movable plate 91 to move downward by a set distance through the fixed plate 92. After the movable plate 91 moves downward by the set distance, the remaining cooling water in the open rack 3 is quickly squeezed out from the drain pipe 7, thereby reducing the heat exchange time between the remaining cooling water and the heat-conducting rod 41, thereby preventing the temperature of the liquid in the mixing chamber from being too low, thereby facilitating the dissolution of the surfactant and improving the homogenization effect of the liquid.

[0045] S5: After the movable plate 91 moves downward, it drives the groove block 101 to move downward, and the groove block 101 drives the mounting ring 102 to move downward, and the mounting ring 102 drives the heat insulation ring 103 to move downward. During the downward movement, the heat insulation ring 103 contacts the outer wall of the heat-conducting rod 41, and scrapes off the water droplets attached to the outer wall. After the movable plate 91 moves downward a set distance, the bottom end of the mounting ring 102 contacts the inner upper end of the open frame 3, and the heat insulation ring 103 seals the gap between the mounting ring 102 and the heat-conducting rod 41. The groove block 101 covers the upper end of the heat-conducting rod 41, and the heat insulation ring 103 scrapes off the water droplets attached to the outer wall, so that the heat at the upper end of the heat-conducting rod 41 will not be released into the open frame 3, thereby ensuring that the upper end of the heat-conducting rod 41 does not dissipate heat, thereby ensuring that the liquid temperature in the mixing chamber meets the requirements.

[0046] Example 2

[0047] After the first valve 63 is closed, cooling water remains in the open rack 3 and is slowly discharged from the drain pipe 7. The discharge takes a certain amount of time. During the discharge process, the residual cooling water continues to exchange heat with the heat-conducting rod 41. When the surfactant is stirred and homogenized, the temperature of the liquid in the mixing chamber is too low due to the continuous heat exchange of the residual cooling water with the heat-conducting rod 41, which is not conducive to the dissolution of the surfactant, thereby reducing the homogenization effect of the liquid. Figure 1-6 As another preferred embodiment of the present invention, on the basis of Example 1, it further includes an extrusion mechanism 9, which includes a movable plate 91, a fixed plate 92, and an electric telescopic rod 93. The movable plate 91 is slidably and sealedly connected to the open rack 3. The movable plate 91 is used to squeeze out the remaining cooling water in the open rack 3. The fixed plate 92 is fixedly connected to the movable plate 91. The fixed plate 92 is used to drive the movable plate 91 to move in the vertical direction. The electric telescopic rod 93 is fixedly connected to the upper end of the interior of the installation chamber. After the electric telescopic rod 93 is started, it drives the fixed plate 92 to move in the vertical direction. The telescopic end of the electric telescopic rod 93 is fixedly connected to the fixed plate 92.

[0048] Working process: The controller controls the electric telescopic rod 93 to start. After the electric telescopic rod 93 is started, it drives the movable plate 91 to move downward a set distance through the fixed plate 92. After the movable plate 91 moves downward a set distance, the cooling water remaining in the open rack 3 is quickly squeezed out from the drain pipe 7, reducing the heat exchange time between the residual cooling water and the heat-conducting rod 41, thereby avoiding the temperature of the liquid in the mixing chamber from being too low, which is beneficial to the dissolution of the surfactant and improves the homogenization effect of the liquid.

[0049] Example 3

[0050] After the movable plate 91 is moved downward to quickly squeeze the remaining cooling water in the open rack 3 out of the drain pipe 7, after the remaining cooling water is drained, the cooling water contacts the heat-conducting rod 41, and the cooling water remains on the heat-conducting rod 41. When the heat-conducting rod 41 is heated, the cooling water on the heat-conducting rod 41 will vaporize, lowering the temperature of the heat-conducting rod 41. As a result, it is impossible to ensure that the liquid temperature in the mixing chamber meets the requirements during the surfactant dissolution process. Figure 1-7 As another preferred embodiment of the present invention, based on Example 2, it further includes a sealing mechanism 10, which includes a groove block 101, a mounting ring 102 and a thermal insulation ring 103. The groove block 101 is fixedly connected to the bottom end of the movable plate 91. The groove block 101 is used to cover the upper end of the heat-conducting rod 41 to prevent heat dissipation from the upper end of the heat-conducting rod 41. The mounting ring 102 is fixedly connected to the inner bottom end of the groove block 101. The mounting ring 102 is used to install the thermal insulation ring 103. The groove block 101 cooperates with the heat-conducting mechanism 4. The thermal insulation ring 103 is fixedly connected to the mounting ring 102. The thermal insulation ring 103 is a thermal insulation rubber ring.

[0051] Working process: After the movable plate 91 moves downward, it drives the groove block 101 to move downward, the groove block 101 drives the mounting ring 102 to move downward, and the mounting ring 102 drives the heat insulation ring 103 to move downward. During the downward movement, the heat insulation ring 103 contacts the outer wall of the heat-conducting rod 41, and scrapes off the water droplets attached to the outer wall. After the movable plate 91 moves downward a set distance, the bottom end of the mounting ring 102 contacts the inner upper end of the open frame 3, and the heat insulation ring 103 seals the gap between the mounting ring 102 and the heat-conducting rod 41. The groove block 101 covers the upper end of the heat-conducting rod 41, and the heat insulation ring 103 scrapes off the water droplets attached to the outer wall, so that the heat at the upper end of the heat-conducting rod 41 will not be released into the open frame 3, thereby ensuring that the upper end of the heat-conducting rod 41 does not dissipate heat, thereby ensuring that the liquid temperature in the mixing chamber meets the requirements.
