[0028] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments. In the following description, different "an embodiment" or "embodiments" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.
[0029] The present application will be further described in detail in combination with the drawings and embodiments.
[0030] As Figure 1 and Figure 2 An embodiment of the present application provides a material leaching device, which comprises a tank body 1, a stirring mechanism 2 and a vacuum pipe 3.

[0032] The stirring mechanism 2 is coaxially arranged in the tank body 1.
[0033] The lower end of the vacuum pipe 3 is connected to a filtering component, and the upper end of the vacuum pipe 3 penetrates the top wall of the tank body 1 and is connected to a vacuum device.
[0034] The working process of the material leaching device is as follows:
[0035] When using the device, first, an extractant is added into the tank body 1 through the liquid inlet 5, and then solid raw materials are added into the tank body 1 through the feeding port 4. The liquid inlet 5 and the feeding port 4 are closed, and then the stirring mechanism 2 is started to uniformly stir and mix the solid raw materials and the extractant.
[0036] When the soluble solids in the solid raw materials are fully extracted by the extractant, the vacuum device is started, and the leaching juice in the tank body 1 is extracted to the juice storage tank 12 through the vacuum pipe 3. The solid raw materials are intercepted by the filtering component and remain in the tank body 1. At this time, the valve of the liquid discharge pipe 9 is opened, and a small amount of liquid residue that cannot be extracted by the vacuum pipe 3 is discharged out of the tank body 1 through the first filter screen 8 and the liquid discharge pipe 9. Then, the bottom cover 7 is opened, and the remaining solid raw material residue in the tank body 1 is discharged.
[0037] Through the above process, the leaching juice is extracted and stored in the juice storage tank 12, so that the leaching juice and the solid raw materials are separated, and the efficiency of material leaching is improved.
[0038] Specifically, the liquid inlet 5 is provided with a valve, and the feeding port 4 is provided with a manhole cover, so as to separate the gas phase space inside and outside the tank body 1.
[0039] Specifically, the vacuum device is a vacuum pump 10, the upper end of the vacuum pipe 3 is connected to one end of a conveying pipe 11, the other end of the conveying pipe 11 penetrates the top wall of the juice storage tank 12 and extends to the bottom of the juice storage tank 12, one end of a negative pressure pipe 13 is connected to the upper end of the juice storage tank 12, and the other end of the negative pressure pipe 13 is connected to the inlet of the vacuum pump 10. When the vacuum pump 10 is started, a negative pressure is formed in the juice storage tank 12, and a pressure difference is formed between the two ends of the vacuum pipe 3, so that the leaching juice in the tank body 1 flows to the juice storage tank 12.
[0040] Specifically, the stirring mechanism 2 includes a stirring motor and a stirring shaft. The stirring motor is fixedly installed on the top wall of the tank body 1, and the output shaft of the stirring motor penetrates the top wall of the tank body 1 and is coaxially connected to the stirring shaft.

[0044] When the stirring mechanism 2 is working, the stirring shaft drives the mixed solution to rotate and mix in the tank 1. After the solid raw material components of the mixed solution hit the surface of the tank plate 14, they sweep over both sides of the tank plate 14. During the above process, the soluble solids in the solid raw materials hit the surface of the tank plate 14, which increases the crushing speed of the soluble solids, thereby increasing the dissolution and extraction speed of the soluble solids.
[0045] like Figure 1 As shown, in a specific embodiment, the filter component is a cylinder 16, the upper end of which is coaxially connected to the vacuum tube 3, and the circumferential sidewall of the cylinder 16 is evenly distributed with multiple through holes.
