DETAILED DESCRIPTION

[0027] As Figures 1 to 6 shown, a liquid mixing device for chemical processing includes a mixing barrel 1, a transmission mechanism 2, and a liquid inlet pipe 7. The inside of the mixing barrel 1 is rotatably connected with a hollow rotating shaft 3. The outside of the hollow rotating shaft 3 is provided with a hollow stirring rod 4. The surface of the hollow stirring rod 4 is provided with a liquid discharge hole 5. The top of the hollow rotating shaft 3 is provided with a feeding mechanism 6.

[0028] The feeding mechanism 6 includes a communication pipe 61 fixedly connected to the top of the mixing barrel 1. The outside of the communication pipe 61 is fixedly connected with four liquid conveying pipes 62, which are equally distributed around the communication pipe 61. The outside of the liquid conveying pipe 62 is provided with a control valve 63. The top of the liquid conveying pipe 62 is provided with a liquid inlet box 64. The top of the mixing barrel 1 is provided with a mounting plate 65. The inside of the communication pipe 61 is provided with a primary mixing assembly 66. It should be noted that the transmission mechanism 2 is a commonly used power transmission mechanism in existing equipment, mainly composed of a motor, a pulley, and a transmission belt. The hollow rotating shaft 3 is driven by the pulley transmission, so that the hollow rotating shaft 3 can normally rotate. In addition, the connection between the communication pipe 61 and the liquid conveying pipe 62 is sealed, which can avoid the leakage of liquid raw materials during transportation.

[0029] The top end of the hollow rotating shaft 3 is rotatably connected with the inside of the communication pipe 61, and the hollow rotating shaft 3 is connected with the inside of the communication pipe 61. The transmission mechanism 2 is arranged in the inside of the mixing barrel 1 and is in transmission connection with the hollow rotating shaft 3. The liquid inlet box 64 is in communication with the communication pipe 61 through the liquid conveying pipe 62. The bottom of the liquid inlet box 64 is fixedly connected with the mounting plate 65, and the mounting plate 65 is fixedly connected with the mixing barrel 1. It should be noted that the liquid raw materials in the liquid inlet box 64 are transported through the communication pipe 61, so that multiple liquid raw materials can enter the inside of the hollow rotating shaft 3, and finally be discharged from the liquid discharge hole 5 on the surface of the hollow stirring rod 4 to the mixing barrel 1 to mix with the main liquid raw materials, so that the mixing effect of the liquid raw materials is better.

[0030] The primary mixing assembly 66 includes a support rod 661 fixedly connected to the top end of the hollow rotating shaft 3, and the top of the support rod 661 is fixedly connected with a rotating rod 662. The number of the support rods 661 is four, which are distributed at equal angles on the outer surface of the rotating rod 662. The number of the mixing plates 663 is four, which are distributed at equal distances from top to bottom on the outer surface of the rotating rod 662, so that the stability of the rotating rod 662 during rotation is better, and the primary mixing treatment of various liquids can also be well performed. The outer surface of the rotating rod 662 is fixedly connected with the mixing plates 663. The mixing plates 663 are arranged obliquely, and the size value of the mixing plates 663 is less than half of the radius value of the communication pipe 61, so that the mixing plates 663 can perform primary mixing and stirring treatment on most of the liquids during rotation, and also will not hinder the downward flow of the liquids. It should be noted that the hollow rotating shaft 3 drives the support rod 661 to rotate, so that the mixing plates 663 can rotate to preliminarily mix the various liquid raw materials entering the inside of the communication pipe 61, so that the liquid raw materials entering the mixing barrel 1 are in a mixed state, which is convenient for subsequent more sufficient mixing treatment of all liquid raw materials.

[0031] In this embodiment, first, the liquid raw material with a large mixing amount is delivered to the inside of the mixing barrel 1 through the liquid inlet pipe 7, and then several liquid raw materials with a small mixing amount are poured into different liquid inlet boxes 64. Then, the control valve 63 below the liquid inlet box 64 is opened, so that the liquid raw material in the liquid inlet box 64 can be delivered to the inside of the communication pipe 61 through the liquid delivery pipe 62. When different liquid raw materials enter the inside of the communication pipe 61, the hollow rotating shaft 3 is in a rotating state during the stirring process, so that the support rod 661 also rotates and drives the rotating rod 662 to rotate. The rotating rod 662 rotates to drive the mixing plates 663 on the surface thereof to rotate. The mixing plates 663 can perform stirring and mixing operation on different liquid raw materials during the rotation. Since the mixing plates 663 are arranged obliquely, the downward flow speed of the liquids at this position is slower during the rotation, so that the mixing plates 663 can preliminarily mix the various raw materials, so that the mixing degree of the liquid discharged from the liquid outlet hole 5 is good, thereby improving the mixing efficiency of the chemical liquid raw materials.

[0032] As shown in Figures 6 to 8 The outer surface of the hollow stirring rod 4 is provided with an auxiliary mixing mechanism 8. The auxiliary mixing mechanism 8 includes a gear ring 81 fixedly connected to the inner side surface of the mixing barrel 1, and the inner side surface of the gear ring 81 is engaged with a gear 82. The surface of the hollow stirring rod 4 is provided with a connecting frame 83, the inner side surface of the connecting frame 83 is rotatably connected with a stirring wheel 84, the outer surface of the stirring wheel 84 is coaxially fixedly connected with a first bevel gear 85, the inner side surface of the connecting frame 83 is rotatably connected with a long shaft 86, and the outer surface of the long shaft 86 is coaxially fixedly connected with a second bevel gear 87.

[0033] The gear 82 is fixedly connected with the top end of the long shaft 86 and is rotatably connected with the connecting frame 83 through the long shaft 86. It is to be noted that the gear 82 can drive the second bevel gear 87 to rotate when the gear 82 rotates, so that stable transmission can be achieved, and the hollow rotating shaft 3 can drive the stirring wheel 84 to rotate synchronously when the hollow rotating shaft 3 rotates.

[0034] The first bevel gear 85 is meshingly connected with the second bevel gear 87. It is to be noted that the stirring wheel 84 can rotate with the hollow rotating shaft 3 through the transmission between the first bevel gear 85 and the second bevel gear 87.

[0035] In summary, when the chemical liquid raw materials are mixed, the operator first sends the liquid raw materials with a large mixing amount into the inside of the mixing barrel 1 through the liquid inlet pipe 7, and then pours several liquid raw materials with a small mixing amount into different liquid inlet boxes 64, and then drives the hollow rotating shaft 3 to rotate through the transmission mechanism 2, the hollow rotating shaft 3 drives the hollow stirring rod 4 to rotate, and the hollow stirring rod 4 stirs and mixes the liquid raw materials in the mixing barrel 1 in the rotating process, and then the operator opens the control valve 63 below the liquid inlet box 64 containing the liquid raw materials, so that the liquid raw materials in the liquid inlet box 64 can be sent into the communicating pipe 61 through the liquid outlet pipe 62, and then flow into the hollow rotating shaft 3 from the bottom end of the hollow rotating shaft 3, and then flow into the hollow stirring rod 4 along the hollow rotating shaft 3, and finally be discharged from the liquid discharge hole 5 on the surface of the hollow stirring rod 4 into the mixing barrel 1 to be mixed with the initial input raw materials;

[0036] When different liquid raw materials flow into the communicating pipe 61, the branch rod 661 rotates with the hollow rotating shaft 3, and the rotating rod 662 rotates with the branch rod 661, and the mixing plate 663 on the surface of the rotating rod 662 rotates with the rotating rod 662, so that the different liquid raw materials in the flowing process can be stirred and mixed by the mixing plate 663 in the rotating process. Since the mixing plate 663 is inclined, the flowing speed of the liquid at this position is slower in the rotating process, so that the mixing plate 663 can pre-mix the multiple raw materials, so that the mixing degree of the liquid discharged from the liquid discharge hole 5 is good. Since the pre-mixed liquid raw materials are discharged from the liquid discharge hole 5 on the surface of the hollow stirring rod 4 in the rotating process of the hollow stirring rod 4, the liquid can be quickly mixed with the liquid raw materials previously sent into the mixing barrel 1 after being sprayed, so that the mixing efficiency of the chemical liquid raw materials is improved.

[0037] The hollow stirring rod 4 drives the gear 82 arranged at the top of the hollow stirring rod 4 to rotate in the rotating process, and the gear 82 rotates and drives the long shaft 86 to rotate under the transmission of the gear ring 81, the long shaft 86 drives the second bevel gear 87 to rotate, the second bevel gear 87 drives the first bevel gear 85 to rotate, and the first bevel gear 85 drives the stirring wheel 84 to rotate, so that the stirring wheel 84 can stir the premixed liquid raw material sprayed out in the vertical direction, the initial diffusion range of the premixed liquid raw material is larger, the liquid raw material mixing efficiency can be further improved, and the mixing effect of the chemical liquid raw material is better.

[0038] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
