Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to an automatic stirring tank for quantitative mixing of lotion solution. Background Technology

[0002] Lotions are often formulated with multiple components, and the mixture needs to be stirred during the formulation process to ensure uniformity.

[0003] A search revealed a prior art pharmaceutical mixing tank (publication number: CN208097932U), comprising a mixing tank body and a mixing shaft disposed within the mixing tank body. The lower end of the mixing shaft is equipped with a bottom mixing device, which includes a cylindrical connecting sleeve and a mixing mesh. The connecting sleeve is fitted onto the mixing shaft, and a threaded through hole is provided on the side of the connecting sleeve, with a bolt installed in the threaded through hole. The mixing mesh is composed of several mixing rings, each with a convex arc-shaped inverted J-shaped structure. The mixing rings are flexible, with the arc-shaped end connected to the bottom of the connecting sleeve and the other end connected to the bottom of the mixing shaft. The mixing rings are arranged around the same central axis.

[0004] Existing technologies mainly use a stirring rod to drive the stirring ring and stirring mesh in a circular motion to compress the liquid and mix it. However, due to the limited volume and structure of the stirring ring, the stirring rod cannot rotate too fast, the mixing time is long, and the efficiency is low. The large volume of the stirring ring results in poor overall dynamic balance, and it produces a lot of noise and vibration during rotation, indicating that there is room for optimization.

[0005] Therefore, we propose an automatic mixing tank for quantitatively dispensing of detergent solutions. Utility Model Content

[0006] The present invention mainly solves the above-mentioned technical problems of slow stirring speed and low efficiency, and provides an automatic stirring tank for quantitative mixing of detergent solution.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automatic stirring tank for quantitative proportioning of lotion solution, comprising:

[0008] The outer shell forms a sealed tank structure, with pipes for feeding and discharging materials at the top and bottom, and a stirring shaft rotatably installed inside the outer shell;

[0009] A stirring structure, set inside the outer shell, is used to mix liquids. The stirring structure includes a jet shell, a flow guide, an impeller, and blades.

[0011] In a preferred embodiment of this utility model, the top center of the spray housing is provided with a circular hole for feeding, the guide shroud is funnel-shaped, the smaller end face of the guide shroud is fixedly connected to the spray housing, and the guide shroud is directly opposite the circular hole.

[0012] In a preferred embodiment of this utility model, a sealed bearing is fixedly installed on the inner bottom surface of the outer shell, a rotating shaft is fixedly installed on the bottom of the impeller, the rotating shaft is fixedly connected to the inner ring of the sealed bearing, and the stirring shaft is fixedly connected to the center position of the top of the impeller.

[0013] In a preferred embodiment of this invention, the agitation structure further includes a shearing plate, a jet pipe, and a shearing groove. Several shearing plates are fixedly installed on the inner wall of the outer shell, and each shearing plate has several shearing grooves.

[0016] Beneficial effects

[0017] This invention provides an automatic mixing tank for quantitatively dispensing of detergent solutions. It has the following beneficial effects:

[0018] 1. This automatic mixing tank for quantitative mixing of detergent solution uses a stirring shaft to drive an impeller to rotate inside a spray housing. The impeller drives multiple blades to move in a circular motion. The spray housing enhances the back pressure around the blades. The liquid inside the spray housing is discharged from the slot under the pushing action of the blades. As a result, the liquid outside the spray housing has a relatively high pressure. The liquid outside the spray housing enters the spray housing chamber through the guide shroud and forms a low-pressure area at the center of the bottom of the housing. The liquid can form a vortex. The liquid is mixed by sucking it into the spray housing and spraying it out. This method is highly efficient and has low noise. At the same time, the impeller and blades can be integrally molded, with precise dynamic balance, less vibration during high-speed rotation, long maintenance cycle, and good durability.

[0019] 2. This automatic mixing tank for quantitative proportioning of detergent solution features a spiral shear plate. The shear plate is fixedly installed on the inner wall of the outer shell and does not interfere with the spray shell and the stirring shaft. Due to the vortex formed during the circumferential motion of the impeller and blades, the liquid level is high near the inner wall of the outer shell and low in the center. During the liquid flow, the liquid is squeezed and sheared by multiple shear grooves. At the same time, the liquid sprayed from the inside is discharged from the spray pipe and shot towards the shear plate, further promoting liquid mixing and achieving the purpose of improving mixing effect and efficiency.

[0026] An automatic mixing tank for quantitative dispensing of lotion solutions, such as Figure 1 and Figure 2 As shown, it includes:

[0027] The outer shell 10 forms a sealed tank structure. Both the top and bottom of the outer shell 10 are provided with pipes for feeding and discharging. The pipe at the top of the outer shell 10 is used for feeding, and a metering valve is installed on the pipe at the top of the outer shell 10. The metering valve is used to add a quantitative amount of liquid into the outer shell 10 to achieve the purpose of precise proportioning. The inner part of the outer shell 10 is equipped with a stirring shaft 11 for rotation. A motor is fixedly installed on the top of the outer shell 10. The output shaft of the motor is fixedly connected to the stirring shaft 11 and drives the stirring shaft 11 to rotate.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an agitation structure is installed inside the outer casing 10 for mixing liquids. The agitation structure includes a jet housing 20, a flow guide 21, an impeller 22, and blades 23. The jet housing 20 is fixedly installed to the outer casing 10. The impeller 22 is rotatably connected to the outer casing 10 and fixedly connected to the stirring shaft 11. Several blades 23 are fixedly installed on the top of the impeller 22. The flow guide 21 is fixedly connected to the jet housing 20 and can pour liquid into the jet housing 20. The side wall of the jet housing 20 is provided with a groove for discharging material. The jet housing 20 forms a circle. The cylindrical structure has a disc 22, which is circular and has a diameter smaller than the inner diameter of the spray housing 20. The disc 22 is located inside the cavity of the spray housing 20. The top center of the spray housing 20 has a circular hole for feeding. The guide shroud 21 is funnel-shaped and its smaller end face is fixedly connected to the spray housing 20. The guide shroud 21 is directly opposite the circular hole. A sealed bearing is fixedly installed on the inner bottom surface of the outer shell 10. A rotating shaft is fixedly installed on the bottom of the disc 22 and is fixedly connected to the inner ring of the sealed bearing. The stirring shaft 11 is fixedly connected to the top center of the disc 22.

[0029] In this design, the impeller 22 is driven to rotate inside the spray housing 20 by the stirring shaft 11. The impeller 22 drives multiple blades 23 to move in a circular motion. The back pressure around the blades 23 is enhanced by the spray housing 20. The liquid inside the spray housing 20 is discharged from the slot under the pushing action of the blades 23. As a result, the liquid outside the spray housing 20 has a relatively high pressure. The liquid outside the spray housing 20 enters the spray housing 20 chamber from the guide shroud 21. A low-pressure area is formed at the bottom center of the outer shell 10, and the liquid can form a vortex. The liquid is mixed by sucking the liquid into the spray housing 20 and spraying it out. This method is efficient and has low noise. At the same time, the impeller 22 and the blades 23 can be integrally molded, with precise dynamic balance, less vibration during high-speed rotation, long maintenance cycle, and good durability.

[0030] like Figure 3 As shown, the agitation structure also includes a shear plate 30, a jet pipe 31, and a shear groove 32. Several shear plates 30 are fixedly installed on the inner wall of the outer shell 10. Each shear plate 30 has several shear grooves 32. The jet pipe 31 is fixedly connected to the jet shell 20. The jet pipe 31 can guide the liquid discharged from the inside of the jet shell 20 to one side of the shear plate 30. The shear plate 30 forms a spiral plate. The shear groove 32 forms a groove with a trapezoidal cross section. The width of the shear groove 32 increases uniformly from top to bottom. The jet pipe 31 is fixedly installed in the groove of the jet shell 20. Several jet pipes 31 are arranged on the circumferential surface of the jet shell 20, corresponding to the shear plates 30.

[0031] In this scheme, as a supplementary explanation to the above scheme, a spiral shear plate 30 is set. The shear plate 30 is fixedly installed on the inner side wall of the outer shell 10 and does not interfere with the spray shell 20 and the stirring shaft 11. Since the impeller 22 and the blade 23 will form a vortex during the circumferential motion, the liquid level near the inner wall of the outer shell 10 is high and the liquid level in the center is low. During the liquid flow, the liquid is squeezed and sheared by multiple shear grooves 32. At the same time, the liquid sprayed out of the 20 will be discharged from the spray pipe 31 and shot towards the shear plate 30, further promoting liquid mixing and achieving the purpose of improving mixing effect and efficiency.

[0032] The working principle of this utility model is as follows: The pipe at the top of the outer casing 10 is used for feeding. A metering valve is installed on the pipe at the top of the outer casing 10. The feed port of the metering valve is connected to a delivery pump. The metering valve is connected to a controller. Through the metering valve, a quantitative amount of liquid is added to the outer casing 10 to achieve the purpose of precise proportioning.

[0033] The stirring shaft 11 drives the impeller 22 to rotate inside the spray housing 20. The impeller 22 drives multiple blades 23 to move in a circular motion. The back pressure around the blades 23 is enhanced by the spray housing 20. The liquid inside the spray housing 20 is discharged from the slot under the pushing action of the blades 23. As a result, the liquid outside the spray housing 20 has a relatively high pressure. The liquid outside the spray housing 20 enters the spray housing 20 chamber from the guide shroud 21. A low-pressure area is formed at the bottom center of the outer shell 10, and the liquid can form a vortex. The liquid is mixed by sucking the liquid into the spray housing 20 and spraying it out. A spiral shear plate 30 is provided. The shear plate 30 is fixedly installed on the inner side wall of the outer shell 10 and does not interfere with the spray housing 20 and the stirring shaft 11. Since the impeller 22 and the blades 23 will form a vortex during the circular motion, the liquid level near the inner wall of the outer shell 10 is high and the liquid level in the center is low. During the liquid flow, the liquid is squeezed and sheared by multiple shear grooves 32. At the same time, the liquid sprayed out of the 20 will be discharged from the spray pipe 31 and shot towards the shear plate 30, further promoting the liquid mixing.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
