[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Battery powder mixed acid technology is a pretreatment process that converts precious metals in battery powder into corresponding salts (such as sulfates) by mixing battery powder with acid (such as sulfuric acid) to prepare for further recovery of precious metals in subsequent stages. In related technologies, the material mixing equipment mixes materials for too short a time and has a poor mixing effect.

[0034] Reference below Figure 1-Figure 7 A material mixing device according to an embodiment of the present invention is described.

[0035] The material mixing equipment 1 according to the present invention comprises a cylinder 11, a first delivery device 121, a second delivery device 122, a material retention device, a stirring device 14, and a material lifting device. A mixing chamber is formed in the cylinder 11, and a first partition 111, a second partition 112, a third partition 113 and a fourth partition 114 which are connected in sequence are arranged in the mixing chamber; the first delivery device 121 is connected to the cylinder 11 and is suitable for delivering solid materials toward the first partition 111; the second delivery device 122 is connected to the cylinder 11 and extends into the first partition 111 to be suitable for delivering liquid materials; the material retention device is arranged on the inner wall of the second partition 112 and rotates with the cylinder 11; the stirring device 14 is rotatably arranged in the third partition 113 to stir the mixture in the third partition 113; the material lifting device is arranged on the inner wall of the fourth partition 114 and rotates with the cylinder 11.

[0036] According to the material mixing device 1 of the present invention, a barrel 11 is provided, and the barrel 11 is the basis of the material mixing device 1. A mixing chamber for mixing materials is formed in the barrel 11, and the mixing chamber provides space for mixing materials. Four partitions connected in sequence are defined in the mixing chamber, namely a first partition 111, a second partition 112, a third partition 113 and a fourth partition 114, wherein the first partition 111 is connected to a first delivery device 121 for delivering solid materials and a second delivery device 122 for delivering liquid materials. When mixing materials, solid materials and liquid materials (such as battery metal powder and acid solution) can be delivered into the first partition 111 through the first delivery device 121 and the second delivery device 122 respectively. After the solid materials and the liquid materials enter the first partition 111, they can be mixed and released in the first partition 111. The reaction generates salt. At the same time, the mixture passes through the second partition 112, the third partition 113 and the fourth partition 114 in sequence from the first partition 111 and finally enters the device for recovering the mixed material. In this process, the inner wall of the second partition 112 is provided with a material retention device that can rotate with the cylinder 11. The material retention device can hinder the flow of the mixed material and prolong the flow time of the mixed material in the second partition 112, so that the unreacted acid and metal powder in the mixed material can react fully; the third partition 113 is provided with a stirring device 14 that can rotate independently, and the stirring device 14 can stir the mixed material entering the third partition 113 to make the mixture more uniform; the inner wall of the fourth partition 114 is provided with a lifting device that can rotate with the cylinder 11, and the lifting device scatters the mixture to further improve the uniformity of material mixing and ensure the quality of the discharge.

[0037] The material mixing device 1 is provided with a first delivery device 121 and a second delivery device 122, so that the material mixing device 1 can deliver solid materials and liquid materials to the first partition 111 respectively, thereby improving the flexibility of material delivery, so that the solid materials and liquid materials can enter the first partition 111 through different paths and be mixed, which is conducive to the smooth progress of the subsequent mixing process. The material retention device provided in the second partition 112 can effectively extend the residence time of the material in the area as the cylinder 11 rotates, providing sufficient time for the chemical reaction or physical action between the materials, thereby enhancing the mixing effect or promoting the progress of a specific chemical reaction. The rotatable stirring device 14 provided in the third partition 113 can fully stir the mixture to ensure that the material reaches a highly uniform mixing state in the area. The lifting device in the fourth partition 114 can lift the evenly mixed material and spread it in the entire partition as the cylinder 11 rotates, further improving the mixing effect, helping to eliminate the mixing dead corners, and ensuring the quality and consistency of the final product. The mixing chamber is cleverly divided into a first partition 111, a second partition 112, a third partition 113 and a fourth partition 114 which are connected in sequence, so that different materials can be preliminarily mixed, retained for reaction, deeply stirred and finally dispersed in different partitions in sequence, thereby improving the mixing efficiency and accuracy and ensuring the uniformity and quality of material mixing.

[0038] In some embodiments, the material mixing equipment 1 can be tilted so that the heights of the four partitions tend to decrease successively. When mixing materials, the materials can flow in the four partitions with the help of gravity, without the need to set up additional power equipment. The tilt angle of the material mixing equipment 1 can preferably be 7° to 12°.

[0039] In some embodiments, the inner wall of the first partition 111 is provided with an anti-corrosion layer to prevent the liquid material from corroding the cylinder 11 .

[0040] In some embodiments, the cylinder 11 is rotatable, and a driving motor may be provided to drive the cylinder 11 to rotate so as to improve the mixing efficiency of the materials in the mixing chamber.

[0041] According to one embodiment of the present invention, in the axial projection plane of the cylinder 11, the cylinder 11 has a symmetry axis 115 extending in the height direction, and at least part of the second delivery device 122 is accommodated in the first partition 111 and adjacent to the top of the symmetry axis 115 and away from the side of the rotation direction of the cylinder 11. Figure 2As shown, the cylinder 11 has a symmetry axis 115 extending in the height direction in the axial projection plane. Since the cylinder 11 itself rotates (the clockwise direction shown in FIG. 2 is used as the rotation direction of the cylinder 11 in this application), during the rotation of the cylinder 11, when the first delivery device 121 delivers solid materials toward the first partition 111, the solid materials will rotate with the cylinder 11 and accumulate under the action of gravity. Figure 2 In order to allow the liquid material (i.e., the acidic solution) to directly contact and react with the solid material, the second delivery device 122 needs to be located on the side of the symmetry axis 115 away from the rotation direction of the cylinder 11 (i.e., the side close to the solid material), and ensure that the outlet of the second delivery device 122 is directly opposite to the accumulated solid material. For example, at least part of the second delivery device 122 located in the first partition 111 can be set directly above the accumulation of solid material, so that the delivery position of the liquid material can be accurately controlled, so that the liquid material can directly contact and react with the solid material, thereby improving the material mixing efficiency, reducing the corrosion damage of the liquid material (acidic solution) to the inner wall of the first partition 111, and extending the service life of the material mixing equipment 1.

[0042] According to one embodiment of the present invention, the material retention device includes: a material retention plate 13, which is constructed in multiple forms, and the multiple material retention plates 13 are spaced apart from each other on the inner circumferential wall of the second partition 112, and each material retention plate 13 extends along the axis of the cylinder 11 and is tilted toward the rotation direction of the cylinder 11.

[0043] The material retention device in the second partition 112 includes a plurality of material retention plates 13, such as Figure 5 As shown, a plurality of material retention plates 13 are arranged at intervals in the axial direction of the inner wall of the second partition 112, and a plurality of material retention plates 13 are also arranged at intervals in the circumferential direction of the inner wall of the second partition 112. It can be simply understood that the plurality of material retention plates 13 are arranged in multiple rows and columns on the inner wall of the second partition 112, and each material retention plate 13 extends along the axis of the cylinder 11, which means that these material retention plates 13 can cover most of the space inside the cylinder 11, thereby effectively affecting the flow and mixing of the material; at the same time, the material retention plates 13 are also inclined toward the rotation direction of the cylinder 11. Through the intervals between the plurality of material retention plates 13 and the inclination angle of each material retention plate 13, the material can be more finely divided and retained, the contact area and time between the material and the material retention plate 13 are increased, and the flow of the material in the second partition 112 is hindered, the time for the material to pass through the second partition 112 is extended, so that the liquid material can fully react with the solid material; in addition, when the material moves between the material retention plates 13, it will be subjected to shearing and friction, which helps to break the agglomerates in the material, promote the full mixing between the materials, and improve the material mixing efficiency.

[0044] According to one embodiment of the present invention, the material retention plate 13 forms an angle α with the axis of the cylinder 11, and satisfies: 5°<α<15°. Figure 5 As shown, during the arrangement, the angle α between the material retention plate 13 and the axis of the cylinder 11 can be limited to between 5° and 15°. If α is less than 5°, the material retention function of the material retention plate 13 will be insufficient, and the solid material and the liquid material will not be able to fully react. If α is greater than 15°, the material retention plate 13 will seriously hinder the flow of the mixed material in the second partition 112, making it difficult or even impossible for the mixed material to flow into the third partition 113, ultimately affecting the mixing effect of the materials. Therefore, limiting the value range of α to between 5° and 15° can ensure that the mixed material can flow normally while extending the time for the mixed material to pass through the second partition 112, so that the solid material and the liquid material can fully react. Among them, in actual arrangement, the value of α can be preferably 10°.

[0045] According to one embodiment of the present invention, the stirring device 14 includes: a stirring shaft 141 and a stirring paddle 142, at least a portion of the stirring shaft 141 is rotatably disposed in the third partition 113 and extends along the axis of the cylinder 11, and the rotation direction of the stirring shaft 141 is opposite to the rotation direction of the cylinder 11; the stirring paddle 142 is sleeved on at least a portion of the outer circumference of the stirring shaft 141, and at least a portion of the stirring paddle 142 protrudes radially from the stirring shaft 141 and rotates with the stirring shaft 141.

[0046] like Figure 3 As shown, a stirring device 14 is provided in the third partition 113, and the stirring device 14 includes a rotatable stirring shaft 141 and a stirring paddle 142 sleeved on the stirring shaft 141. At least part of the stirring shaft 141 is located in the third partition 113 and extends along the axis of the cylinder 11. The stirring paddle 142 can rotate with the stirring shaft 141. It should be noted that the rotation direction of the stirring shaft 141 is opposite to the rotation direction of the cylinder 11. For example, the cylinder 11 is Figure 2 The stirring shaft 141 rotates clockwise, and correspondingly, the stirring shaft 141 should rotate counterclockwise. The rotation direction of the stirring shaft 141 is opposite to the rotation direction of the barrel 11, which generates a reverse shear force, which helps to break the rotation flow pattern that the material may form in the barrel 11 and promote more complete mixing between the materials. At the same time, the counter-rotating stirring shaft 141 can drive the stirring paddle 142 to more effectively push the material from the edge of the barrel 11 to the center, or from the center to the edge, reducing the accumulation of the material on the inner wall of the barrel 11 and reducing the mixing dead angle. The stirring paddle 142 protrudes from the stirring shaft 141 in the radial direction, which increases the contact area between the stirring paddle 142 and the material and improves the stirring efficiency.

[0047] In some embodiments, an additional driving motor may be provided to drive the stirring shaft 141 to rotate, and it is only necessary to ensure that the rotation direction of the stirring shaft 141 is opposite to the rotation direction of the barrel 11 .

[0048] According to one embodiment of the present invention, a plurality of stirring paddles 142 are arranged in an axial direction of the cylinder 11 at intervals in the second partition 112, and each stirring paddle 142 is provided with at least one blade 143. The plurality of blades 143 are arranged in a circumferential direction of the cylinder 11 at intervals, and an angle β is formed between the blades 143 and the axis of the cylinder 11, and the angle β satisfies: 5°<β<15°. A plurality of stirring paddles 142 are arranged in an axial direction of the cylinder 11 at intervals in the second partition 112, and each stirring paddle 142 is provided with at least one blade 143, which can enhance the fluidity and shear force of the material during the mixing process, so that the material can be stirred and mixed more fully. The spaced arrangement of the plurality of stirring paddles 142 can also stir the material at different positions, promote the mixing of the material in the entire cylinder 11, and thus improve the overall mixing efficiency. The paddles 143 are arranged at intervals in the circumferential direction of the cylinder 11, and form an angle β of 5° to 15° with the axis of the cylinder 11, so that the paddles 143 can not only radially stir the material when rotating, but also generate a certain axial driving force, slowing down the tendency of the material to flow toward the fourth partition 114, extending the flow time of the material in the third partition 113, so that the material can be fully mixed in the third partition 113. This radial and axial stirring method helps to break the stratification or agglomeration that may be formed in the material, so that the material can be more evenly distributed in the cylinder 11, achieving a higher mixing uniformity.

[0049] Among them, the value of β is limited to 5°~15°, which is a more reasonable range. When β<5°, the blade 143 will have less effect on slowing down the flow of materials, making it difficult for the materials to have enough time to be fully mixed in the third partition 113; when β>15°, the stirring device 14 will seriously hinder the flow of the mixed material in the third partition 113, making it difficult or even impossible for the mixed material to flow into the fourth partition 114, ultimately affecting the mixing effect of the materials. Therefore, the value range of the angle β (5°<β<15°) is optimized and selected, which can ensure sufficient stirring intensity to promote material mixing, and will not cause the materials to be unable to flow into the fourth partition 114 due to excessive angles, affecting the final discharge. In actual layout, the value of β can be preferably 10°.

[0050] In some embodiments, as shown in the figure, three stirring paddles 142 can be set on a stirring shaft 141, and each stirring paddle 142 is provided with two blades 143 spaced from each other, that is, 6 blades 143 are supplied in the third partition 113 at this time, and in the axial projection surface of the cylinder 11, the angle between the centers of the projections of two adjacent blades 143 can be 60°, that is, the 6 blades 143 are evenly distributed, which can improve the uniformity of the stirring device 14 when stirring the material and the stability during the rotation process.

[0051] According to one embodiment of the present invention, the material lifting device includes: a material lifting plate 15, which is structured as a plurality of material lifting plates 15, and the plurality of material lifting plates 15 are arranged on the inner peripheral wall of the fourth partition 114 at intervals, and the extension direction of each material lifting plate 15 is parallel to the axis of the cylinder 11. Figure 1 and Figure 6 As shown, multiple lifting plates 15 are spaced apart in the axial direction of the inner wall of the fourth partition 114, and multiple lifting plates 15 are also spaced apart in the circumferential direction of the inner wall of the fourth partition 114. It can be simply understood that multiple lifting plates 15 are arranged in multiple rows and columns on the inner wall of the fourth partition 114, and each lifting plate 15 extends along the axis of the cylinder 11, which means that these lifting plates 15 can cover most of the space inside the cylinder 11, thereby effectively affecting the flow and mixing of materials. When the cylinder 11 rotates, the lifting plates 15 can effectively use the centrifugal force generated by the rotation of the cylinder 11 to lift the materials attached to the inner wall of the cylinder 11 or deposited at the bottom. The existence of the lifting plates 15 increases the contact area and friction between the materials and the inner wall of the cylinder 11, making it easier for the materials to be thrown away from the cylinder wall and thrown to the center of the cylinder 11, thereby promoting the lifting and dispersion of the materials. The raised materials are more widely distributed in the cylinder 11, which increases the chances of collision and mixing between the material particles, helps to break the agglomeration or stratification of the materials, and enables the materials to be more evenly distributed in the cylinder 11. At the same time, since the lifting plates 15 are arranged at intervals, the gaps between them allow the materials to pass through and continue to be mixed, further improving the mixing uniformity.

[0052] According to one embodiment of the present invention, the material mixing device 1 further comprises: a vibration device 16, which is disposed on at least part of the outer surface of the cylinder 11 and is suitable for striking the cylinder 11 to drive the material adhering to the inner wall of the cylinder 11 to fall off. Figure 1 and Figure 7 As shown, at least part of the outer surface of the cylinder 11 is provided with a vibration device 16, which can produce a knocking action and directly act on the cylinder 11, thereby driving the material adhered to the inner wall of the cylinder 11 to fall off, reducing the accumulation and adhesion of the material on the inner wall of the cylinder 11. The reduction of material adhesion means that more material can participate in the mixing process instead of being bound to the inner wall of the cylinder 11, improving the fluidity and mixing efficiency of the material, so that the material can be more fully stirred and mixed to achieve the expected mixing effect. At the same time, the long-term accumulation of adhered materials may cause wear or corrosion to the inner wall of the cylinder 11, thereby affecting the overall performance and life of the equipment. The use of the vibration device 16 helps to remove the adhered materials in time, reducing their potential damage to the inner wall of the cylinder 11, thereby extending the service life of the equipment.

[0053] According to one embodiment of the present invention, the vibration device 16 includes: a base 161 and a pendulum 162, the base 161 is arranged on the outer surface of the cylinder 11 corresponding to the first partition 111; the pendulum 162 is connected to the base 161 and is suitable for knocking the cylinder 11 when the cylinder 11 rotates to a certain angle. The design of the pendulum 162 being connected to the base 161 allows the pendulum 162 to knock on the cylinder 11 by using the action of gravity or centrifugal force when the cylinder 11 rotates to a specific angle. This design ensures the accuracy and controllability of the knocking action, so that the vibration device 16 can carry out targeted removal of materials adhered to the inner wall of the cylinder 11. Compared with the traditional continuous vibration method, the pendulum 162 design can knock only when the cylinder 11 rotates to a specific position, thereby reducing unnecessary energy consumption and making the vibration device 16 more energy-saving and efficient. In addition, the pendulum 162 design makes the maintenance and replacement of the vibration device 16 simpler and more convenient. When the pendulum 162 or the base 161 is worn or malfunctions, they can be replaced or repaired separately without disassembling or replacing the entire vibration device 16.

[0054] According to one embodiment of the present invention, a mounting groove 163 is formed on the base 161 and is open toward the rotation direction of the cylinder 11. One end of the pendulum 162 is rotatably received in the mounting groove 163. The pendulum 162 is suitable for rotating and striking the cylinder 11 when the base 161 rotates to the top with the cylinder 11. Figure 2 As shown, the mounting groove 163 on the base 161 is open toward the rotation direction of the cylinder 11, so that the pendulum 162 can only rotate in the open direction of the mounting groove 163 and complete the knocking action. For example, when the base 161 rotates to the top with the cylinder 11 and continues to rotate, the pendulum 162 rotates naturally by gravity and leaves the mounting groove 163 through the gap of the mounting groove 163 until it contacts the cylinder 11 to complete the knocking action. When the base 161 continues to rotate a certain angle with the cylinder 11 (for example, when it rotates to the bottom), the pendulum 162 rotates back under the action of gravity and returns to the mounting groove 163 along the open mouth of the mounting groove 163 to achieve the return action. The design of the mounting groove 163 not only optimizes the knocking time, but also improves the knocking efficiency. Since the pendulum 162 rotates naturally with the rotation of the cylinder 11, the knocking action is faster and more powerful, and the materials adhering to the inner wall of the cylinder 11 can be knocked off effectively. The whole process does not require additional driving force, which reduces the energy input required for knocking.

[0055] In some embodiments, the vibration devices 16 are configured as a plurality of groups arranged at intervals on at least a portion of the outer surface of the first partition 111 and corresponding to each other. Each group of vibration devices 16 includes a pendulum 162 and a mounting slot 163. For example, Figure 2Six groups of vibration devices 16 are arranged in two areas. The first area is located at the upper part of the outer surface of the cylinder 11 where the first partition 111 is located as shown in the figure; the second area is located at the lower part of the outer surface of the cylinder 11 where the first partition 111 is located as shown in the figure, and the two areas are staggered in the axial direction of the cylinder 11. This arrangement can increase the coverage area of ​​the vibration force when the vibration device 16 strikes, ensuring that the adhered material on the inner wall of the first partition 111 can obtain a good vibration shedding effect. Figure 2 The angle γ between two adjacent vibration devices 16 in the two areas shown in the figure can be arranged to be 30°. For 6 vibration devices 16, if they are evenly distributed in the circumferential direction of the cylinder 11, the knocking is dispersed and the knocking effect is poor; and if the arrangement area of ​​the vibration device 16 is increased, it is easy to cause excessive knocking force and damage the cylinder 11.
