After the mixed liquid is layered in the extraction tank, an extraction device is generally inserted from the mouth of the extraction tank to extract the liquid of the corresponding layer. However, during the process of inserting the extraction device into the liquid, the outer wall of the extraction device may contact the liquid of different layers, thereby generating mixed contamination and reducing the purity of the extracted solution, which needs to be improved.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 The utility model is described in further detail.

[0030] Reference Figure 1 , is a manganese-lithium solution extraction device disclosed in the utility model, comprising an extraction tank 1, the extraction tank 1 is fixed on an external frame, a feed port 11 and an extraction port 12 are provided on the top of the extraction tank 1, and a discharge valve 13 is provided on the bottom of the extraction tank 1. The present application improves the extraction structure of the extraction tank 1, thereby reducing the use frequency of the extraction port 12 and the discharge valve 13.

[0031] The side wall of the extraction tank 1 is provided with a plurality of joints 2 rotating along the height direction. A bend pipe 21 is fixedly connected to one end of the joint 2 facing the extraction tank 1. The bend pipe 21 is bent at a right angle. The end of the bend pipe 21 away from the joint 2 is located inside the extraction tank 1. The outer wall of the extraction tank 1 is provided with an observation window extending in the vertical direction.

[0032] Reference Figure 1 and Figure 2The observation window includes a main observation window 14 and an auxiliary observation window 15. The size of the main observation window 14 is larger than that of the auxiliary observation window 15. The main observation window 14 is used to visually observe the liquid state in the extraction tank 1. The larger size facilitates direct observation. The auxiliary observation window 15 corresponds to the position of the bend pipe 21. The auxiliary observation window 15 is used to specifically observe the position of the end of each bend pipe 21 in the liquid layer. The length direction of the auxiliary observation window 15 is arranged along the vertical direction. The auxiliary observation window 15 is arranged on both the front and rear sides of the extraction tank 1, so that the light on the rear side of the extraction tank 1 can pass through the two auxiliary observation windows 15 and the liquid layer, so that personnel can observe more clearly.

[0033] Reference Figure 2 A spotlight 3 is slidably disposed outside the extraction tank 1, and the spotlight 3 faces the auxiliary observation window 15 at the rear side of the extraction tank 1. The spotlight 3 is a lighting lamp with a conical focusing cover, and the spotlight 3 can focus the light in the irradiation direction, thereby improving the light's ability to penetrate the liquid layer, so that personnel can clearly see the stratified state of the liquid layer and the position of the curved pipe 21.

[0034] The sliding connection structure between the spotlight 3 and the extraction tank 1 is as follows: a bracket 31 is fixed on the back side of the extraction tank 1, a slide rail 32 is fixed on the bracket 31 in the vertical direction, and a slider 33 is fixed to the spotlight 3, and the slider 33 is slidably connected to the slide rail 32. The slide rail 32 is a whole piece that runs through the slider 33, and the slider 33 has a large thickness, so that the slider 33 and the slide rail 32 have a large contact area, the guiding effect is better and the sliding is smooth. A person can push the slider 33, thereby driving the slider 33 and the spotlight 3 to move, thereby adjusting the height position of the spotlight 3 relative to the liquid layer. When the person's observation line of sight and the spotlight 3 are at the same horizontal plane, the brightness of the light entering the human eye can be significantly improved, and the error in judging the liquid level caused by light refraction can be reduced.

[0035] The slider 33 is threadedly connected with a locking bolt 34, and the end of the locking bolt 34 abuts against the outer wall of the slide rail 32. The height position of the slider 33 is locked by the locking bolt 34. In addition, by adjusting the tightening degree of the locking bolt 34, the sliding friction between the slider 33 and the slide rail 32 can also be adjusted, so that the slider 33 can be kept at the height position by static friction in the case of non-human driving. When sliding is required, it can be directly pulled by hand without frequently turning the locking bolt 34, which is convenient for use.

[0036] Reference Figure 3 , the connector 2 is a self-closing quick connector, which is a prior art. When the self-closing quick connector is connected, the inside can be conducted, and when it is separated, it automatically becomes a closed state to prevent the connector 2 from leaking when the pipeline is not connected. It should be noted that a water seal ring is set between the connector 2 and the extraction tank 1 to establish a rotation seal, so when the connector 2 rotates, the contact position between it and the extraction tank 1 will not leak water.

[0037] The end of the elbow 21 away from the joint 2 is tapered, which is more conducive to determining the position of the inlet of the elbow 21 and avoiding pumping liquid from other layers.

[0038] Reference Figure 2 and Figure 3 The outer wall of the joint 2 is fixed with an external hexagonal screw head 22, and the outer wall of the extraction tank 1 is fixed with a hook 16, and the hook 16 is hung with a spanner 4 that matches the external hexagonal screw head 22. Through the external hexagonal screw head 22, the spanner 4 can be conveniently clamped, thereby driving the joint 2 to rotate. Through the long force arm of the spanner 4, the staff can accurately adjust the angle of the joint 2, thereby adjusting the position of the end of the elbow 21; the spanner 4 is dedicated to the device, and by setting the hook 16, it can prevent the spanner 4 from being lost when it is randomly placed anywhere.

[0039] The implementation principle of the manganese-lithium solution extraction device of the present application is: pour the solution generated by the treatment of waste batteries into the extraction tank 1, and layer the liquid by dosing and standing, and the composition of each layer of liquid is different. When the liquid of the corresponding layer needs to be extracted, the personnel first adjust the height position of the spotlight 3 to correspond to the height of the boundary line of the layer to be extracted, and then observe the boundary line between the liquid layers and the elbow 21 through the auxiliary observation window 15, and rotate the joint 2 through the wrench 4, thereby driving the elbow 21 to rotate, so that the end of the elbow 21 away from the joint 2 is close to the inner bottom position of the corresponding liquid layer.

[0040] Then connect the pipeline to connector 2, and the liquid of the corresponding liquid layer enters the pipeline through the bend 21 and the inside of connector 2, and the liquid of this layer can be discharged. At the same time, it can be observed through the auxiliary observation window 15. When the liquid layer is completely drained, close the valve on the pipeline or directly remove the connection between the pipeline and connector 2.

[0041] By using this device, when taking out the liquid of the required layer, there will be no problem of the outer wall of the extraction device contacting the liquid of different layers, thereby avoiding mixed contamination and ensuring that the extracted solution has high purity. In addition, the discharge of the liquid does not rely on the power source, and the required liquid layer can be discharged by the gravity and water pressure of the liquid in the extraction tank 1, which is more energy-saving and convenient.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
