Abstract
Description
Technical Field
[0001] This utility model belongs to the field of liquid mixing technology, and in particular relates to a high-efficiency liquid mixing device. Background Technology
[0002] In chemical production, it is often necessary to mix powdered materials with liquids to prepare solutions. Since the dissolution of powdered materials takes time, stirring is often required to accelerate the process. Using stirred tanks to mix multiple components is a common method for liquid preparation. Material mixing is generally carried out using a stirring paddle, and different paddle types can be selected depending on the material properties. However, traditional methods relying solely on stirring are often insufficient to achieve highly uniform mixing or require considerably long mixing times. This results in long single-tank production cycles and high energy consumption during the stirring cycle, which is detrimental to improving productivity. Utility Model Content
[0003] The purpose of this invention is to provide a high-efficiency mixing and dispensing device to improve the mixing and dispensing efficiency and make up for the shortcomings of existing stirring and mixing devices.
[0004] Therefore, the present invention adopts the following technical solution:
[0005] A high-efficiency mixing and dispensing device includes a mixing vessel. The top of the mixing vessel is provided with a liquid inlet and a solid material inlet, and the bottom is provided with a mixed liquid outlet. A stirring paddle is centrally located inside the mixing vessel and is connected to a stirring motor fixed to the top of the mixing vessel. A circulation pump is fixed to the outside of the side wall of the mixing vessel. One end of the circulation pump is connected to the bottom of the mixing vessel through a pipe, and the other end is connected to a liquid phase distributor inside the mixing vessel through a pipe. The liquid phase distributor is located directly below the stirring paddle.
[0006] The liquid phase distributor is ring-shaped, and multiple downward-facing liquid distribution pipes are evenly arranged on the inner and outer sides of the liquid phase distributor. The liquid distribution pipes include an outer liquid distribution pipe located on the lower outer side of the liquid phase distributor and an inner liquid distribution pipe located on the lower inner side of the liquid phase distributor. The outer liquid distribution pipes and the inner liquid distribution pipes are evenly arranged on the gas distribution ring in an alternating manner.
[0007] Compared with the prior art, the present invention has the following beneficial effects:
[0008] By using a circulating pump and a liquid phase distributor in conjunction with an agitator, the mixing speed can be accelerated, the mixing time and energy consumption can be reduced, and the solid and liquid phases in the mixing vessel can be mixed more evenly, thereby improving the efficiency of chemical production. Attached Figure Description

[0010] Figure 2 for Figure 1A schematic diagram of the structure of the liquid phase distributor.
[0011] In the diagram, 1-mixing vessel, 2-stirring paddle, 3-stirring motor, 4-liquid inlet, 5-solid material inlet, 6-mixed liquid outlet, 7-circulating pump, 8-liquid phase distributor, 9-external liquid distribution pipe, 10-internal liquid distribution pipe. Detailed Implementation
[0012] The present invention will be further explained below with reference to the accompanying drawings.
[0013] like Figures 1-2 As shown, a high-efficiency mixing and dispensing device includes a mixing vessel 1. The top of the mixing vessel 1 is provided with a liquid inlet 4 and a solid material inlet 5, and the bottom is provided with a mixed liquid outlet 6. A stirring paddle 2 is centrally located inside the mixing vessel 1, and the stirring paddle 2 is connected to a stirring motor 3 fixed on the top of the mixing vessel 1. A circulation pump 7 is fixed to the outside of the side wall of the mixing vessel 1. One end of the circulation pump 7 is connected to the bottom of the mixing vessel 1 through a pipe, and the other end is connected to a liquid phase distributor 8 inside the mixing vessel 1 through a pipe. The liquid phase distributor 8 is located directly below the stirring paddle 2.
[0014] The liquid phase distributor 8 is ring-shaped, and multiple downward-facing liquid distribution ports are evenly arranged on the inner and outer sides of the liquid phase distributor 8. The liquid distribution ports include an outer liquid distribution port 9 located on the lower outer side of the liquid phase distributor 8 and an inner liquid distribution port 10 located on the lower inner side of the liquid phase distributor 8. The outer liquid distribution port 9 radiates outward, and the inner liquid distribution port 10 converges inward. The outer liquid distribution port 9 and the inner liquid distribution port 10 are evenly arranged on the gas distribution ring in an alternating manner.
[0015] In use, according to the process ratio, liquid and solid materials are added to the mixing vessel through the liquid inlet 4 and solid material inlet 5 respectively. The stirring motor 3 is started to drive the stirring paddle 2 to mix, while the circulation pump 7 is started to circulate the liquid phase. To prevent clogging, a filter screen can be installed at the inlet of the circulation pump to remove large solid particles. Because the inner liquid distribution pipe 10 is arranged inwards, the liquid entering the inner liquid distribution pipe 10 is sprayed outwards in a concentrated manner. Under the action of the axial flow shear force generated at the bottom of the stirring paddle, it is fully mixed with the axially flowing material. The outer liquid distribution pipe 9 is arranged radially outwards, causing the liquid entering the outer liquid distribution pipe 9 to be sprayed outwards in a radial manner. Under the action of the turbulent laminar flow shear force between the axial and radial flows generated at the bottom of the stirring paddle 2, it is fully mixed with the turbulent laminar flow material, eliminating material mixing blind zones, enhancing the mixing effect, and improving mixing efficiency. The downward-facing design of the outer liquid distribution port 9 and the inner liquid distribution port 10 prevents solid material from directly entering the liquid phase distributor and causing accumulation and blockage, thus maintaining smooth flow within the distributor.
[0016] The above-mentioned device eliminates the stirring blind zone of traditional impeller-type mixing devices, accelerates the mixing of solid and liquid materials, improves mixing efficiency, and ensures the stable operation of chemical production.
