Description

[0003] However, traditional chemical engineering solution mixing devices still have some shortcomings in practical applications.

In unidirectional stirring, the solution forms a stirring vortex during the stirring process, which makes it impossible for the solution to be fully mixed laterally. This results in low mixing quality and efficiency. Furthermore, during the stirring process, different types of solutions will separate into layers due to their different densities, which further affects the mixing quality.

Detailed Implementation
[0033] 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.
[0034] Reference Figures 1-2This utility model provides an embodiment of a chemical engineering solution mixing device, including a support base 1 for supporting the device. The bottom of the support base 1 is a support base plate. Three sets of support legs are fixedly connected to the upper part of the support base plate away from the center. A mixing tank 2 is fixedly connected to the upper surface of the support base 1. The bottom end of the inner wall of the mixing tank 2 is set as an arc surface to facilitate the discharge of the mixed solution. The top of the left surface of the mixing tank 2 is penetrated and fixedly connected to a feed pipe 3 for raw materials to enter the mixing tank 2. The lower surface of the mixing tank 2 is penetrated and fixedly connected to a discharge pipe 4 for the mixed solution to be discharged. The discharge pipe 4 is located at the lower middle position of the mixing tank 2. The mixed solution in the mixing tank 2 can be discharged from the discharge pipe 4. The interior of the mixing tank 2 is provided with a bidirectional stirring mechanism for stirring and mixing chemical engineering solution raw materials. The upper surface of the mixing tank 2 is provided with a positioning component for positioning the bidirectional stirring mechanism.
[0035] Reference Figures 1-3 The bidirectional stirring mechanism includes an active stirring component, which includes a fixed frame 51. The fixed frame 51 is U-shaped with the opening facing downwards. A motor 52 is installed on the upper surface of the fixed frame 51. The motor 52 is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. The output shaft of the motor 52 is fixedly connected to a rotating shaft 53. After the motor 52 is started, it can drive the rotating shaft 53 to rotate. A U-shaped plate 54 is fixedly connected to the lower surface of the rotating shaft 53. The centers of the rotating shaft 53 and the U-shaped plate 54 are located on the same axis. A stirring blade 55 for forward stirring of chemical engineering solution raw materials is fixedly connected to the inner surface of the U-shaped plate 54. Multiple sets of stirring blades 55 are arranged longitudinally and evenly distributed on the left and right sides of the inner surface of the U-shaped plate 54.
[0036] Reference Figures 1-3 The middle section of the discharge pipe 4 is equipped with a valve for controlling the opening and closing of the discharge pipe 4. The valve is a solenoid valve, which is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. The rotating shaft 53 passes through and is rotatably connected to the inner surface of the fixed frame 51. The fixed frame 51 provides support for the rotating shaft 53.
[0037] Reference Figure 2 , Figure 4 , Figure 5The bidirectional stirring mechanism also includes a driven stirring assembly, which includes a bevel gear 61. Bevel gear 61 is fixedly connected to the upper part of the outer wall of the rotating shaft 53. Bevel gear 61 and the rotating shaft 53 rotate synchronously. A bevel gear 62 is rotatably connected to the right end of the inner surface of the fixed frame 51. A guide rod 67 is fixedly connected to the right end of the inner surface of the fixed frame 51. Bevel gear 62 is located above the guide rod 67. The bottom end of bevel gear 62 meshes with a bevel gear 63. Rotation of bevel gear 62 drives rotation of bevel gear 63. In this technical solution, bevel gear 62 is driven by bevel gear 61. As can be seen from the attached drawings, bevel gear 61 and bevel gear 63 rotate in opposite directions at equal speeds. A connecting rod 64 is fixedly connected to the lower surface of bevel gear 63. An annular groove 68 is provided on the upper half of the outer wall of the connecting rod 64. A stirring rod 65 is slidably connected to the lower half of the outer wall of the connecting rod 64. A stirring paddle 66 is fixedly connected to the outer wall of the stirring rod 65. The connecting rod 64, bevel gear 63, stirring rod 65 and stirring paddle 66 will rotate synchronously. Multiple sets of stirring paddles 66 are provided and evenly distributed on the outer wall of the stirring rod 65. The stirring paddles 66 and stirring blades 55 are longitudinally staggered. With the cooperation of bevel gear 1 61, bevel gear 2 62 and bevel gear 3 63, the stirring paddles 66 and stirring blades 55 will stir in opposite directions, which can avoid the generation of stirring vortices caused by unidirectional stirring and improve the stirring effect.
[0038] Reference Figure 2 , Figure 4 , Figure 5 Bevel gear 61 and bevel gear 62 mesh. The left end of guide rod 67 is slidably connected to the inner wall of annular groove 68. Guide rod 67 can maintain the height stability of bevel gear 63 and connecting rod 64 without affecting their normal rotation. Rotating shaft 53 passes through the inner surfaces of bevel gear 63, connecting rod 64 and stirring rod 65. Stirring rod 65 passes through the upper surface of mixing tank 2. The outer wall of stirring rod 65 is in contact with the inner wall of mixing tank 2, which can avoid the original chemical engineering solution. The material seepage is prevented because the outer wall of the rotating shaft 53 and the inner surfaces of the bevel gear 63, connecting rod 64, and stirring rod 65 are in contact with each other, thus preventing the chemical engineering solution raw materials from seeping into the gaps. The centers of the motor 52, mixing tank 2, rotating shaft 53, bevel gear 61, bevel gear 63, connecting rod 64, and stirring rod 65 are all on the same axis, which ensures the stability of the motor 52, mixing tank 2, rotating shaft 53, bevel gear 61, bevel gear 63, connecting rod 64, and stirring rod 65 during operation and avoids motion interference.
[0039] Reference Figure 1 , Figure 2 , Figure 4The positioning component includes a fixing block 72, which is fixedly connected to the upper surface of the support base 1. A guide block 73 is fixedly connected to the right surface of the fixing block 72. A guide plate 71 is fixedly connected to the outer wall of the stirring rod 65. The guide plate 71 is set in an inclined shape. There are two sets of guide blocks 73, which are distributed longitudinally at equal intervals. The guide plate 71 is engaged between the two sets of guide blocks 73. When the guide plate 71 rotates, it will be squeezed by the guide blocks 73, which will drive the guide plate 71, the stirring rod 65 and the stirring paddle 66 to move longitudinally back and forth. The longitudinal back and forth movement range of the stirring paddle 66 is smaller than the distance between the stirring paddle 66 and the stirring blade 55, which can avoid collision. Furthermore, the longitudinal back and forth movement of the stirring paddle 66 when it rotates will cause the chemical engineering solution raw material being stirred to move, further improving the stirring effect. The centers of the guide plate 71 and the stirring rod 65 are aligned.
[0040] Working principle: First, the chemical engineering solution raw material is injected into the mixing tank 2 through the feed pipe 3. Then, the motor 52 is started. The output shaft of the motor 52 drives the rotating shaft 53 to rotate. The rotating shaft 53 drives the stirring blade 55 to rotate in the forward direction through the U-shaped plate 54, so as to initially stir the solution in the mixing tank 2.
[0041] When the rotating shaft 53 rotates, the first bevel gear 61 fixed on the upper part of its outer wall rotates synchronously. The first bevel gear 61 meshes with the second bevel gear 62, driving the second bevel gear 62 to rotate. The second bevel gear 62 further drives the third bevel gear 63, which meshes with it, to rotate in the opposite direction. The third bevel gear 63 drives the stirring rod 65 and the stirring paddle 66 to rotate in the opposite direction through the connecting rod 64, forming a bidirectional stirring effect. This avoids the generation of stirring vortices caused by unidirectional stirring and can improve the mixing effect.
[0042] An inclined guide plate 71 is fixed to the outer wall of the stirring rod 65. The guide plate 71 is engaged between two sets of guide blocks 73. When the stirring rod 65 rotates, the guide plate 71 is squeezed by the guide blocks 73, which drives the stirring rod 65 and the stirring paddle 66 to reciprocate along the longitudinal direction. This movement further agitates the solution and further improves the mixing effect.
[0043] After mixing is complete, open the valve on the discharge pipe 4, and the well-mixed solution will be discharged from the bottom of the mixing tank 2.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
