Description

Technical Field

[0001] This utility model relates to the field of rinsing agent production technology, and in particular to a special stirring equipment for rinsing agent production. Background Technology

[0002] For example, Chinese patent CN216367956U discloses a special equipment for producing rinsing agents. It can quantitatively add raw materials, and then the stirring motor works to drive the stirring shaft to rotate. The stirring blades on the side wall also rotate together, so that the two raw materials can be fully mixed. With the heating of the heating tube, the activity of the reaction solution is maintained, making the reaction more thorough.

[0003] However, the paddle stirring mechanism in the above application can only perform local stirring of materials in one direction. The fluid flow pattern in the equipment is simple and it is difficult to form effective turbulence. This results in low mixing efficiency of high-viscosity materials or liquids and powders. Especially for viscous systems, uneven mixing between the upper and lower layers is likely to occur. Furthermore, when adding powder raw materials, due to the lack of targeted dispersion measures, the powder is very easy to absorb water and agglomerate in local areas, forming clumps that are difficult to disperse. This not only prolongs the stirring time but also affects the stability and cleaning effect of the finished rinsing agent. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dedicated mixing equipment for the production of rinsing agents, which solves the technical problems of existing technologies having a single mixing mode, poor mixing effect, and easy clumping of powder raw materials.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a special stirring device for the production of rinsing agents, including a reaction vessel and support legs fixed to the four corners of the bottom of the reaction vessel. A rotating shaft is rotatably connected to the top of the reaction vessel, and a large dispersing disc is installed at the bottom of the rotating shaft. A small dispersing disc is installed at the top of the rotating shaft, and drive motors for driving the rotating shaft and rotating the rotating shaft are respectively installed on the upper and lower sides of the reaction vessel. A mixing mechanism to prevent powder agglomeration is provided on the reaction vessel, and a temperature control mechanism to control the reaction temperature is provided inside the reaction vessel.

[0006] A further improvement is that the small dispersion disk is 100-200mm from the bottom of the reactor, and the large dispersion disk is one-third to one-half the height of the reactor from the small dispersion disk.

[0007] A further improvement is that the area of ​​the large dispersion disk is twice that of the small dispersion disk, the tooth spacing of the large dispersion disk is 20-40mm, and the tooth spacing of the small dispersion disk is 10-20mm.

[0008] A further improvement is that the mixing mechanism includes a Venturi ejector installed on the side of the reactor, and the Venturi ejector is lower than the small dispersion plate. A powder tank is installed on the Venturi ejector, and a water pump is installed on the reactor. The outlet of the water pump is connected to a delivery pipe at the top of the Venturi ejector.

[0009] A further improvement is that a liquid injection pipe is fixedly installed on the left side of the top of the reactor, and a flow monitoring valve is installed on the liquid injection pipe; a feed pipe is fixedly installed on the right side of the top of the reactor; and a discharge pipe is fixedly installed on the right side of the bottom of the reactor, and an electric sealing valve is installed on the discharge pipe.

[0010] A further improvement is that the temperature control mechanism includes a water injection pipe fixed to the side of the reactor, a serpentine heat exchange tube installed at the end of the water injection pipe extending into the reactor, an outlet pipe fixed to the end of the serpentine heat exchange tube extending to the outside of the reactor, and a temperature sensor installed on the inner wall of the reactor.

[0011] By employing the above technical solution, this utility model provides a special stirring device for the production of rinsing agents, which has at least the following beneficial effects:

[0012] 1. This utility model uses a large dispersion disc and a small dispersion disc to rotate in opposite directions to form a countercurrent flow field. The small dispersion disc at the bottom pushes the fluid upward, while the large dispersion disc in the middle and upper part pushes the fluid downward. Intense turbulence is formed within the distance between the two discs, producing a combined effect of longitudinal cutting and transverse tearing, which shortens the time for the material to go from an agglomerated state to a dispersed state and improves the stirring efficiency.

[0013] 2. This utility model uses a water pump to input the liquid at the bottom of the reactor into the Venturi ejector through a delivery pipe. The powder weighed in the powder tank is drawn into the Venturi ejector for mixing and then sprayed out at high speed. Since the Venturi ejector is positioned lower than the small dispersion plate, it ensures that the sprayed powder is directly captured by the small dispersion plate and drawn into the high-speed fluid shearing zone formed by the rotation of the small dispersion plate. This allows the powder to be quickly mixed into the fluid and prevents the powder from clumping.

[0014] 3. This utility model uses a temperature sensor to monitor the temperature of the fluid inside the reactor in real time, so that coolant can be introduced into the serpentine heat exchange tube through the water injection pipe in a timely manner to cool the fluid inside the reactor. The coolant after heat exchange is discharged and circulated through the water outlet pipe. Alternatively, hot water can be introduced to heat the fluid according to actual needs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Given the current limitations of existing mixing technologies, such as their simplistic mixing modes, poor mixing efficiency, and tendency to cause powder agglomeration, this embodiment provides a dedicated mixing device for rinsing agent production. This device enables the material to circulate through vertical convection, promoting overall material movement, improving mixing efficiency, and preventing powder agglomeration. Please refer to... Figures 1-4 The special mixing equipment for the production of this rinsing agent includes a reaction vessel 1 and support legs 2 fixed to the four corners of the bottom of the reaction vessel 1. A rotating shaft 3 is rotatably connected to the top of the reaction vessel 1, and a large dispersion disc 4 is installed at the bottom of the rotating shaft 3. A rotating shaft 5 is rotatably connected to the bottom of the reaction vessel 1, and a small dispersion disc 6 is installed at the top of the rotating shaft 5. Drive motors 7 are installed on the upper and lower sides of the reaction vessel 1 to drive the rotating shaft 3 and rotating shaft 5 to rotate. A mixing mechanism 8 is provided on the reaction vessel 1 to prevent powder from agglomerating. A temperature control mechanism 9 is provided inside the reaction vessel 1 to control the reaction temperature.

[0027] The small dispersion disc 6 is 100-200mm from the bottom of the reactor 1, and the large dispersion disc 4 is one-third to one-half the height of the reactor 1 from the small dispersion disc 6. After the raw materials and additives are put into the reactor 1, the two drive motors 7 are started to drive the rotating shaft 3 and the rotating shaft 5 to rotate in opposite directions, which in turn drives the large dispersion disc 4 and the small dispersion disc 6 to rotate in opposite directions, with the small dispersion disc 6 rotating at a higher speed than the large dispersion disc 4. At this time, the small dispersion disc 6 stirs the materials at the bottom of the reactor 1, forming a strong shear zone, which stirs the clumps that have settled at the bottom of the reactor 1. The material is broken up. At this time, the large dispersion disk 4, which rotates in the opposite direction, forms a wide shear surface, which breaks up the viscous fluid or bubble layer floating on the top and generates an axial suction effect, peeling off the material attached to the inner wall of the reactor 1 and bringing it into the mainstream zone for redispersing. The two disks work together to form a countercurrent flow field between the two disks. The small dispersion disk 6 at the bottom pushes the fluid upward, while the large dispersion disk 4 in the middle and upper part pushes the fluid downward. Intense turbulence is formed within the distance between the two disks, which produces a combined effect of longitudinal cutting and transverse tearing, shortening the time for the material to go from an agglomerated state to a dispersed state and improving the stirring efficiency.

[0028] The area of ​​the large dispersion disc 4 is twice that of the small dispersion disc 6. The tooth spacing of the large dispersion disc 4 is 20-40 mm, while the tooth spacing of the small dispersion disc 6 is 10-20 mm. The appropriate spacing can prevent high-viscosity materials from getting stuck due to excessively dense spacing, and can also prevent insufficient shearing force due to excessively sparse spacing.

[0029] To prevent powder materials from absorbing water and clumping during feeding, which would affect the quality of the final rinsing agent, the device is also equipped with a mixing mechanism 8, including a Venturi jet injector 81 installed on the side of the reactor 1. The Venturi jet injector 81 is lower than the small dispersion disc 6. A powder tank 82 is installed on the Venturi jet injector 81, and a water pump 83 is installed on the reactor 1. The outlet of the water pump 83 is connected to a delivery pipe 84 at the top of the Venturi jet injector 81. The water pump 83 pumps the liquid at the bottom of the reactor 1 into the Venturi jet injector 81 through the delivery pipe 84. The powder weighed in the powder tank 82 is drawn into the Venturi jet injector 81 for mixing and then sprayed out at high speed. Since the Venturi jet injector 81 is lower than the small dispersion disc 6, it ensures that the sprayed powder is directly captured and drawn into the high-speed fluid shearing zone formed by the rotation of the small dispersion disc 6, thereby quickly mixing the powder into the fluid and preventing powder clumping.

[0030] A liquid injection pipe 85 is fixedly installed on the top left side of the reactor 1, and a flow monitoring valve 86 is installed on the liquid injection pipe 85. A feeding pipe 87 is fixedly installed on the top right side of the reactor 1, and a discharge pipe 88 is fixedly installed on the bottom right side of the reactor 1, and an electric sealing valve 89 is installed on the discharge pipe 88. Liquid additives are poured into the reactor 1 through the liquid injection pipe 85. The flow monitoring valve 86 monitors the flow rate of the liquid additives in real time to achieve precise feeding. A large amount of raw materials are introduced into the reactor 1 through the feeding pipe 87. The mixed materials can be discharged through the discharge pipe 88 by opening the electric sealing valve 89.

[0031] Example 2

[0032] Based on Example 1, such as Figures 1-4 As shown, since the high-speed rotation of the two dispersion discs causes the fluid to heat up, which in turn causes the heat-sensitive components in the rinsing agent to become ineffective, the device is also equipped with a temperature control mechanism 9. The temperature control mechanism 9 includes a water injection pipe 91 fixed to the side of the reactor 1. A serpentine heat exchange tube 92 is installed at the end of the water injection pipe 91 that extends into the reactor 1. A water outlet pipe 93 extending to the outside of the reactor 1 is fixed to the end of the serpentine heat exchange tube 92. A temperature sensor 94 is installed on the inner wall of the reactor 1. The temperature sensor 94 monitors the temperature of the fluid in the reactor 1 in real time, so that coolant is promptly introduced into the serpentine heat exchange tube 92 through the water injection pipe 91 to cool the fluid in the reactor 1. The cooled fluid after heat exchange is discharged and circulated through the water outlet pipe 93. Hot water can also be introduced to heat the fluid according to actual needs.
