[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] Battery powder mixed acid technology involves a pretreatment process in which battery powder is mixed with an acid (such as sulfuric acid) to convert precious metals in the powder into corresponding salts (such as sulfates), preparing for further precious metal recovery in subsequent processes. However, in related technologies, material mixing equipment typically mixes materials too quickly, resulting in poor mixing results.

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

[0035] According to the present invention, the material mixing equipment 1 includes a cylinder 11, a first feeding device 121, a second feeding 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 that are connected in sequence are provided in the mixing chamber; the first feeding device 121 is connected to the cylinder 11 and is suitable for feeding solid material toward the first partition 111; the second feeding device 122 is connected to the cylinder 11 and extends into the first partition 111 to be suitable for feeding liquid material; 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 equipment 1 of the present invention, a cylinder 11 is provided. The cylinder 11 is the basis of the material mixing equipment 1. A mixing chamber for mixing materials is formed in the cylinder 11. 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. The first partition 111 is connected to a first feeding device 121 for feeding solid materials and a second feeding device 122 for feeding liquid materials. When mixing materials, solid materials and liquid materials (such as battery metal powder and acid solution) can be fed into the first partition 111 through the first feeding device 121 and the second feeding 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 will pass through the second partition 112, the third partition 113 and the fourth partition 114 in sequence from the first partition 111 and finally enter the device for recovering the mixed material. During 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. 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. The lifting device scatters the mixture to further improve the uniformity of material mixing and ensure the quality of the discharge.

[0037] By providing a first delivery device 121 and a second delivery device 122, the material mixing equipment 1 can deliver solid and liquid materials to the first partition 111, respectively. This improves the flexibility of material delivery and allows solid and liquid materials to enter the first partition 111 through different paths and mix, facilitating 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 materials in this area as the cylinder 11 rotates, providing sufficient time for chemical reactions or physical interactions between the materials, thereby enhancing the mixing effect or promoting the progress of specific chemical reactions. The rotatable stirring device 14 provided in the third partition 113 can fully stir the mixture, ensuring that the materials in this area are highly evenly mixed. The material lifting device in the fourth partition 114 can lift the already evenly mixed materials and spread them throughout the entire partition as the cylinder 11 rotates, further improving the mixing effect, helping to eliminate mixing dead spots, 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 efficiency and accuracy of mixing and ensuring the uniformity and quality of material mixing.

[0038] In some embodiments, the material mixing equipment 1 can be placed at an angle 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 inclination angle of the material mixing equipment 1 can preferably be 7° to 12°.

[0039] In some embodiments, an anti-corrosion layer is provided on the inner wall of the first partition 111 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 of the cylinder 11, the cylinder 11 has a symmetry axis 115 extending in the height direction, and at least a portion 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 Figure 2 is used as the rotation direction of the cylinder 11 in this application), during the rotation of the cylinder 11, when the first feeding device 121 feeds 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 the position to the left of the symmetry axis 115 shown in the figure and close to the bottom, in order to allow the liquid material (i.e., the acidic solution) to directly contact and react with the solid material, the second feeding 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 feeding device 122 is directly opposite to the accumulated solid material. For example, at least part of the second feeding device 122 located in the first partition 111 can be set directly above the accumulation of solid material, so that the feeding 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 peripheral 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 spaced apart in the axial direction of the inner wall of the second partition 112, and a plurality of material retention plates 13 are also spaced apart in the circumferential direction of the inner wall of the second partition 112. This can be simply understood as the plurality of material retention plates 13 being arranged in multiple rows and columns on the inner wall of the second partition 112, and each material retention plate 13 extending along the axis of the cylinder 11, meaning 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. The spacing between the plurality of material retention plates 13 and the inclination angle of each material retention plate 13 can achieve more detailed segmentation and retention of the material, increase the contact area and time between the material and the material retention plates 13, hinder the flow of the material in the second partition 112, prolong the time for the material to pass through the second partition 112, and allow the liquid material to fully react with the solid material. In addition, when the material moves between the material retention plates 13, it will be subjected to shear and friction, which helps to break up agglomerates in the material, promotes sufficient mixing between the materials, and improves the material mixing efficiency.

[0044] According to one embodiment of the present invention, an angle α is formed between the material retention plate 13 and the axis of the cylinder 11, and satisfies: 5°<α<15°. Figure 5 As shown, during 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 and liquid materials 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 it takes for the mixed material to pass through the second partition 112, allowing the solid and liquid materials to fully react. Among them, in actual arrangement, the value of α can preferably be 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 arranged 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 in the figure. Correspondingly, the stirring shaft 141 should rotate counterclockwise. The rotation direction of the stirring shaft 141 is opposite to that of the barrel 11, generating a reverse shear force, which helps to break the rotational flow pattern that may form in the barrel 11 and promote more thorough 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 to the center of the barrel 11, or from the center to the edge, thereby reducing the accumulation of material on the inner wall of the barrel 11 and reducing the mixing dead angle. The stirring paddle 142 protrudes radially from the stirring shaft 141, increasing the contact area between the stirring paddle 142 and the material, thereby improving the stirring efficiency.

[0047] In some embodiments, an additional drive motor may be provided to drive the stirring shaft 141 to rotate. 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 provided in the second partition 112 and are spaced apart in the axial direction of the cylinder 11. Each stirring paddle 142 is provided with at least one blade 143. The plurality of blades 143 are spaced apart in the circumferential direction of the cylinder 11, and an angle β is formed between the blades 143 and the axis of the cylinder 11, and the angle satisfies: 5°<β<15°. A plurality of stirring paddles 142 are provided in the second partition 112 and are spaced apart in the axial direction of the cylinder 11. Each stirring paddle 142 is further provided with at least one blade 143. This can enhance the fluidity and shear force of the material during the mixing process, allowing the material to be more fully agitated and mixed. The spaced-apart arrangement of the plurality of stirring paddles 142 can also stir the material at different positions, promoting the mixing of the material throughout the cylinder 11, thereby improving the overall mixing efficiency. The paddles 143 are spaced apart 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, and allowing the material to be fully mixed in the third partition 113. This radial and axial stirring method helps to break up the stratification or agglomeration that may form 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° to 15°, which is a more reasonable range. When β is less than 5°, the blade 143 will have little effect on slowing down the flow of materials, making it difficult for the materials to have enough time to fully mix in the third partition 113; when β is greater than 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 to ensure sufficient stirring intensity to promote material mixing, while not causing the material to be unable to flow into the fourth partition 114 due to excessively large 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 provided on a stirring shaft 141, and each stirring paddle 142 is provided with two blades 143 spaced apart from each other, that is, 6 blades 143 are supplied in the third partition 113 at this time. 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 constructed in multiple configurations. The multiple material lifting plates 15 are spaced apart from each other on the inner peripheral wall of the fourth partition 114, 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 axially along the inner wall of the fourth partition 114, and multiple lifting plates 15 are also spaced circumferentially along the inner wall of the fourth partition 114. This can be simply understood as the multiple lifting plates 15 being arranged in multiple rows and columns on the inner wall of the fourth partition 114. Each lifting plate 15 extends along the axis of the cylinder 11, meaning that these lifting plates 15 can cover most of the space inside the cylinder 11, thereby effectively affecting the flow and mixing of the material. When the cylinder 11 rotates, the lifting plates 15 can effectively utilize the centrifugal force generated by the rotation of the cylinder 11 to lift material attached to the inner wall of the cylinder 11 or deposited at the bottom. The presence of the lifting plates 15 increases the contact area and friction between the material and the inner wall of the cylinder 11, making it easier for the material to be thrown away from the cylinder wall and toward the center of the cylinder 11, thereby promoting the lifting and dispersion of the material. The raised materials are more widely distributed within the cylinder 11, increasing the chances of collision and mixing between material particles, helping to break up possible agglomeration or stratification of the materials, and allowing the materials to be more evenly distributed within the cylinder 11. Furthermore, 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 mixing uniformity.

[0052] According to one embodiment of the present invention, the material mixing device 1 further comprises: a vibration device 16, which is provided on at least a portion of the outer surface of the cylinder 11 and is adapted to strike 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 a portion of the outer surface of the cylinder 11 is provided with a vibration device 16. The vibration device 16 can generate a knocking motion 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 in 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, allowing the material to be more fully stirred and mixed to achieve the desired mixing effect. At the same time, long-term accumulation of adhered material 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 promptly remove adhered material, 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 utilizing 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, allowing the vibration device 16 to 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 adapted to rotate and strike the cylinder 11 when the base 161 rotates to the top along with the cylinder 11. Figure 2 As shown, the mounting slot 163 on the base 161 is open in the direction of rotation of the cylinder 11, so that the pendulum 162 can only rotate in the open direction of the mounting slot 163 and complete the tapping action. For example, when the base 161 rotates to the top with the cylinder 11 and continues to rotate, the pendulum 162 naturally rotates under the action of gravity and leaves the mounting slot 163 through the gap in the mounting slot 163 until it contacts the cylinder 11 to complete the tapping 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 slot 163 along the open mouth of the mounting slot 163 to complete the return action. The design of the mounting slot 163 not only optimizes the timing of tapping, but also improves the efficiency of tapping. Since the pendulum 162 rotates naturally with the rotation of the cylinder 11, the tapping action is faster and more powerful, and can effectively knock off the material adhering to the inner wall of the cylinder 11. The entire process does not require additional driving force, reducing the energy input required for tapping.

[0055] In some embodiments, the vibration devices 16 are configured as a plurality of groups spaced apart and corresponding to each other on at least a portion of the outer surface of the first partition 111. 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 set up in the cylinder, and the six groups of vibration devices 16 are divided into 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 circumference of the cylinder 11, the knocking will be dispersed and the knocking effect will be poor; and if the arrangement area of ​​the vibration devices 16 is increased, it is easy to cause excessive knocking force and damage the cylinder 11.
