[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0027] First, combine Figures 1 to 3 The solid-liquid conveying fluidized device according to the embodiment of the utility model is described, which is used for preparing and conveying solid materials and liquids and has a wide range of application scenarios.

[0028] like Figures 1 to 3 As shown, the solid-liquid conveying fluidization device of the embodiment of the utility model includes: a storage tank and a fluidization module.

[0029] Specifically, Figures 1 to 3 As shown, in this embodiment, a discharge port 11 is provided at the bottom of the storage tank, and the storage tank stores solid materials and liquids; a fluidizing module is arranged in the storage tank 1, and the output end of the fluidizing module is connected to the discharge port 11, and the fluidizing module is provided with a liquid inlet and a solid material inlet. The fluidizing module mixes the liquid and the solid material in proportion and outputs them to the discharge port, thereby realizing precise mixing of the liquid and the solid material, and the overall structure is simple and the cost is low.

[0030] Further, if Figures 1 to 3As shown, in this embodiment, the fluidization module includes: a mixing chamber 2, a plurality of support plates 3, a cofferdam ring 4 and a plurality of liquid inlet pipes 5; the mixing chamber 2 is arranged at the bottom of the storage tank 1, the bottom surface of the mixing chamber 2 is hollow, and a gap is left between the bottom surface of the mixing chamber 2 and the bottom wall of the storage tank 1, and the gap is the solid material inlet, which is convenient for the solid material to smoothly enter the mixing chamber 2, and the mixing chamber 2 provides a mixing space for the solid material and the liquid for fluidization. In this embodiment, the mixing chamber 2 is a conical chamber to ensure that the solid material will not fall along the inclined surface of the conical chamber and will not accumulate on the conical chamber; the support plate 3 is fixed in the mixing chamber 2, and the side of the support plate 3 is connected to the inner wall of the mixing chamber 2, and the plurality of support plates 3 are connected to each other to evenly separate the mixing chamber 2 to form a plurality of areas; the cofferdam ring 4 is fixed at the bottom of the plurality of support plates 3, and the cofferdam ring 4 is connected to the discharge port 11 of the storage tank 1 to output the mixed liquid and solid material. During the solid-liquid fluidization transportation, the cofferdam The ring 4 ensures that the solid material is rolled up by the liquid entering from the liquid inlet pipe 5 and then enters the discharge port 11. When the solid-liquid fluidization is not being transported, the cofferdam ring 4 blocks the solid material from entering the discharge port 11. In the present embodiment, the mixing chamber 2 and the cofferdam ring 4 are connected by the bracket plate 3, and at the same time, it plays the role of dividing the space in the mixing chamber 2 to prevent excessive feeding on one side. The liquid inlet pipe 5 is fixed on the mixing chamber 2 and runs through the mixing chamber 2. One end of the liquid inlet pipe 5 is a liquid inlet and the other end is a liquid outlet. The liquid inlet is located between the material level of the solid material and the liquid level of the liquid to ensure that the liquid always flows inside the liquid inlet pipe 5 without blocking the liquid inlet due to the accumulation of solid materials. The liquid can flow freely into the liquid inlet pipe 5, thereby ensuring the continuous supply of liquid. The outlet of the liquid inlet pipe 5 extends out of the bottom surface of the mixing chamber. Several liquid inlet pipes 5 are evenly distributed on the outside of the cofferdam ring 4. After the liquid and solid materials are mixed outside the cofferdam ring, they bypass the top of the cofferdam ring and enter the discharge port of the storage tank 1. In this embodiment, the liquid is uniformly injected into different areas of the mixing chamber 2 through a plurality of liquid inlet pipes 5, so that the contact area between the solid material and the liquid is increased, the mixing efficiency is improved, and it is helpful to reduce the mixing time, improve the production efficiency, and ensure the consistency of the mixing quality. Further, in this embodiment, at least one liquid inlet pipe 5 is provided for each area, which can ensure that the liquid is evenly distributed in each area, promote the mixing of the liquid and the solid material, and thus achieve a more uniform mixing effect. Different numbers of liquid inlet pipes 5 can be provided according to the ratio of the liquid to the solid material.

[0031] Furthermore, in this embodiment, the amount of liquid entering the mixing chamber 2 through the liquid inlet pipe 5 and the amount of solid entering the conical chamber from the solid material inlet are adjusted by adjusting the number of liquid inlet pipes 5 and the size of the solid material inlet, thereby achieving proportional mixing of liquid and solid materials.

[0032] Furthermore, in this embodiment, a card slot is provided on the bracket plate 3, and several bracket plates 3 are connected to each other through the card slot, making the assembly process simpler and more efficient. The bracket plate 3 can be fixed to the inner wall of the mixing chamber 2 by welding to ensure stability.

[0033] Furthermore, in the present embodiment, the top surface of the cofferdam ring 4 is higher than the stacking height of the solid material in the mixing chamber 2, and can block the solid material from entering the discharge port 11 when the solid-liquid fluidization transportation is not in progress. The bottom surface of the cofferdam ring 4 is connected to the storage tank 1, ensuring that no solid material accumulates inside the cofferdam ring 4, which helps prevent the solid material from clogging the cofferdam ring 4 and ensuring the smooth flow of the discharge port 11. The cofferdam ring 4 is coaxially arranged with the discharge port 11 to ensure that the mixed liquid and solid material enter the discharge port 11 smoothly.

[0034] Furthermore, in this embodiment, the liquid outlet is arranged inside the solid material inlet and is not connected to the bottom wall of the storage tank 1 , thereby ensuring that the liquid can flow freely between the liquid inlet pipe 5 and the bottom wall of the storage tank 1 .

[0035] Embodiment 1: Figure 2 As shown, during the solid-liquid mixed conveying process, the fluidizing module needs to be statically installed in the storage tank 1. At this time, the solid-liquid conveying fluidizing device serves as an intermediate station in the solid-liquid mixed conveying process to ensure that the solid-liquid distribution ratio of the conveyed material is consistent. The storage tank 1 is connected to the external conveying pipeline, and the bracket plate 3 inside the conical cavity is welded or screwed to the bottom of the storage tank 1. During transportation, the solid is washed and rolled up by the liquid entering from the liquid inlet pipe 5 and then enters the discharge port 11.

[0036] Embodiment 2: Figure 3 As shown, in the evaporation crystallization system, the fluidization module needs to be dynamically installed in the storage tank 1. At this time, the storage tank 1 serves as an evaporator, and a stirring shaft 7 is provided inside it. A driving member for driving the stirring shaft to rotate is provided on the top. The conical cavity is fixed at the bottom of the stirring shaft. The support plate 3 inside the conical cavity stirs and disturbs the fluid inside the cavity. The outer surface of the conical cavity is provided with a stirring blade 6. The stirring blade 6 is used to stir the solid material near the conical cavity to prevent the solid material from being compacted. At the same time, the solid-liquid fluidization effect in the conical cavity can be enhanced by adjusting the rotation speed of the stirring shaft 7.

[0037] Above, refer to Figures 1 to 3 The solid-liquid conveying fluidizing device according to the embodiment of the utility model is described, which effectively solves the problem of uneven preparation and conveying of traditional liquids containing solid materials, ensures that solid materials and liquid materials are prepared and conveyed in a certain proportion, avoids engineering application problems such as solid material deposition and pipeline blockage, can improve the overall production operation efficiency, and has wide applicability.
