Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to the present utility model are shown in the drawings, not all of the structures. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] Please see Figures 1 to 4The present invention provides a liquid storage tank for mixing multiple chemical materials, comprising a support 1, a tank body 2, a liquid outlet pipe 3, a main stirring assembly 5, and an auxiliary stirring assembly 6.

[0026] The tank body 2 is fixedly mounted on the support 1. The liquid outlet pipe 3 is located at the bottom end of the tank body 2. A control valve 4 is installed on the liquid outlet pipe 3. The main stirring assembly 5 is located at the top end of the tank body 2 and is used to stir the mixture inside the tank body 2. The auxiliary stirring assembly 6 is located on the side wall of the tank body 2 and at the bottom of the tank body 2. The auxiliary stirring assembly 6 is used to further stir the mixture inside the tank body 2.

[0027] In this process, the operator puts various chemical materials into the tank 2, and the main stirring component 5 stirs the materials to make them evenly mixed. At the same time, the auxiliary stirring component 6 stirs the materials at the bottom of the tank 2. The flow field formed by the auxiliary stirring component 6 and the flow field formed by the main stirring component 5 complement each other, eliminating the stirring dead zone in the tank 2, increasing the flow of materials at the bottom of the tank 2, and further enhancing the mixing effect of the materials.

[0028] In this embodiment, the main stirring assembly 5 includes a first motor 51, a stirring shaft 52, and turbine stirring blades 53. The first motor 51 is fixedly mounted on the top of the tank 2. The stirring shaft 52 passes through the top of the tank 2 and is rotatably connected to the tank 2. The stirring shaft 52 is coaxially fixedly connected to the output shaft of the first motor 51. Multiple turbine stirring blades 53 are provided, and the multiple turbine stirring blades 53 are arranged sequentially along the axial direction of the stirring shaft 52, and are all fixedly connected to the stirring shaft 52.

[0029] In this embodiment, the various turbine-type stirring blades 53 are of different types;

[0030] The first motor 51 drives the stirring shaft 52 to rotate, and the turbine stirring blades 53 follow the stirring shaft 52 to rotate. Multiple turbine stirring blades 53 of different types generate fluid motion in different directions and intensities, so that the main stirring assembly 5 can generate axial and radial flow fields during rotation, thereby enabling a variety of chemical materials to be mixed better.

[0031] In this embodiment, the auxiliary stirring assembly 6 includes a mounting frame 61, a second motor 62, and stirring rods 63. Two mounting frames 61 are provided, respectively located on both sides of the tank body 2 and fixedly connected to the side wall of the tank body 2. Two second motors 62 are provided, each corresponding to one of the two mounting frames 61, and the second motors 62 are fixedly mounted on the mounting frames 61. Two stirring rods 63 are provided, each corresponding to one of the two second motors 62. One end of each stirring rod 63 passes through the side wall of the tank body 2 and is rotatably connected to the tank body 2. The output shaft of the second motor 62 is coaxially and fixedly connected to the stirring rod 63.

[0032] In this embodiment, the rotation direction of the stirring rod 63 is opposite to the rotation direction of the stirring shaft 52;

[0033] Two stirring rods 63 are inclinedly set at the bottom of the tank 2. The stirring rods 63 rotate, causing the material on the side wall of the tank 2 to begin to flow. The rotation direction of the stirring rods 63 is opposite to the rotation direction of the stirring shaft 52, that is, opposite to the rotation direction of the turbine stirring blades 53. When the turbine stirring blades 53 are working, the stirring rods 63 cause the material near the side wall of the tank 2 to flow towards the center. The flow field formed by the stirring rods 63 and the flow field of the turbine stirring blades 53 complement each other, eliminating the stirring dead zone, thereby further improving the mixing effect.

[0034] In this embodiment, a guide pipe 7 is provided at the bottom of the tank 2. The bottom of the guide pipe 7 is open. Multiple guide holes 71 are provided on the side wall of the guide pipe 7. Multiple through holes 531 are provided on the side wall of the turbine stirring blade 53.

[0035] During the mixing process, the material at the bottom of the tank 2 is lifted to the middle of the tank 2 through the guide pipe 7. The material is sprayed out from the guide hole 71, and then enters the flow field formed by the turbine stirring blade 53 through the through hole 531, forming a vertical material flow, which intertwines with the horizontal stirring flow, so that the material is fully mixed in the tank 2.

[0036] In this embodiment, the tank body 2 is provided with a guide plate 8 and a baffle plate 9. Multiple guide plates 8 are provided, and the multiple guide plates 8 are evenly arranged inside the tank body 2 and are all fixedly arranged in the middle of the tank body 2. Multiple baffle plates 9 are provided, and the multiple baffle plates 9 are all fixedly arranged on the side wall of the tank body 2.

[0037] In this process, various chemical materials flow under the action of stirring. The guide plate 8 changes the flow direction of the chemical materials, causing them to generate complex flow motions and increasing the chances of collision and mixing between the materials. The baffle plate 9 effectively prevents the materials from rotating with the turbine stirring blade 53, promoting radial and axial flow of the materials, thereby improving the mixing efficiency.

[0038] In this embodiment, a double-layer spiral coil 10 is fitted inside the side wall of the tank body 2.

[0039] The double-layer spiral coil 10 is connected to an external circulation system. During the chemical material mixing process, the external circulation system provides a heat medium or a cold medium as needed. The heat medium or cold medium flows in the double-layer spiral coil 10 and exchanges heat with the material in the tank 2, thereby maintaining a suitable temperature for the material in the tank and further promoting the mixing of the material.

[0040] This storage tank for mixing multiple chemical materials includes a support 1, a tank body 2, an outlet pipe 3, a main stirring assembly 5, and an auxiliary stirring assembly 6. The tank body 2 is fixedly mounted on the support 1. The outlet pipe 3 is located at the bottom of the tank body 2 and is equipped with a control valve 4. The main stirring assembly 5 is located at the top of the tank body 2 and is used to stir the mixture inside the tank body 2. The auxiliary stirring assembly 6 is located on the side wall of the tank body 2 and at the bottom of the tank body 2. The auxiliary stirring assembly 6 is used to further stir the mixture inside the tank body 2. This storage tank for mixing multiple chemical materials, through the arrangement of various structures, enables the mixture inside the storage tank to be mixed evenly. At the same time, the flow field formed by the auxiliary stirring assembly 6 and the flow field formed by the main stirring assembly 5 complement each other, eliminating dead zones in the stirring process and further enhancing the mixing effect.
