[0053] Example 1

[0054] Embodiment 1 of the present application provides a cutting and dissolving device 100, which can be the structure of the copper dissolution process in the raw foil system 10. It is used to cut and dissolve materials such as copper rods, copper wires, copper plates, and waste foils to form copper sulfate solution.

[0055] Please refer to Figure 1 As shown, this cutting and dissolving device 100 includes a cutting component 110 and a stirring component 120. The cutting component 110 can cut materials in the first direction X and the second direction Y to crush the materials and improve the subsequent dissolution rate. This stirring component 120 corresponds to the material outlet 1111 of the cutting component 110. After the materials are cut and crushed by the cutting component 110, they are put into the stirring component 120, and the stirring component 120 is used to dissolve the materials to facilitate the preparation of copper sulfate solution. After cutting, the materials are directly put into the stirring component 120, without the need for an external shearing structure to shear the materials and without the need to transfer the sheared materials into a copper dissolution tank, optimizing the copper dissolution process and saving costs.

[0056] It can be understood that this cutting and dissolving device 100 can also be applied to other structures and is not limited to the raw foil system 10.

[0057] Among them, refer to Figure 2 As shown, this cutting component 110 includes a housing 111. The housing 111 can be made of stainless steel or other corrosion-resistant materials. The housing 111 is provided with a material inlet 1110, a material outlet 1111, and a material channel 1112. This material channel 1112 is used to connect the material inlet 1110 and the material outlet 1111, and materials enter the material channel 1112 from the material inlet 1110.

[0058] Refer to Figure 2 As shown, the material channel 1112 includes a first part 11120, a second part 11121, and a third part 11122. The first part 11120 is connected to the third part 11122 through the second part 11121.

[0059] Among them, please refer to Figure 2 As shown, the first part 11120 has a funnel-shaped structure, that is, in the direction from the material inlet 1110 to the material outlet 1111, the cross-sectional area of the first part 11120 gradually decreases, so as to facilitate the materials to slide down into the second part 11121 and facilitate the continuous shearing and crushing of the materials.

[0060] Please refer to Figure 2 As shown, the second part 11121 includes a first section and a second section connected to each other. One end of the first section is connected to the end of the first part 11120 away from the material inlet 1110, and the other end is connected to one section of the second section. The other end of the second section is connected to the end of the third part 11122 away from the material outlet 1111.

[0061] In the embodiment of the present application, as Figure 2 shown, the first section is an arc section. In the direction from the material inlet 1110 to the material outlet 1111, the cross-sectional area of this first section first increases and then decreases, or it can first increase and then remain unchanged. In the direction from the material inlet 1110 to the material outlet 1111, the cross-sectional area of the second section gradually decreases to facilitate the flow of the material so that subsequent shearing and copper dissolution can be carried out.

[0062] The third part 11122 is connected to the material outlet 1111, which corresponds to the stirring bin 121 described below. In the direction from the material inlet 1110 to the material outlet 1111, the cross-sectional area of the third part 11122 can remain unchanged or gradually decrease, and it can be specifically designed according to different embodiments.

[0063] In the embodiment of the present application, as Figure 1 and Figure 2 shown, this cutting assembly 110 further includes a first cutting member 112. At least part of the first cutting member 112 is disposed in this material passage 1112. Part of the first cutting member 112 is disposed in the first section of the above-mentioned second part 11121. The material is cut in the first direction X by the first cutting piece 1121 disposed in the first section to reduce the size of the material.

[0064] In the embodiment of the present application, as Figure 1 and Figure 2 shown, the cutting assembly 110 further includes a second cutting member 113. The second cutting member 113 is disposed on the side of the first cutting member 112 away from the material inlet 1110. At least part of the second cutting member 113 is disposed in this material passage 1112. The second cutting member 113 disposed in the above-mentioned third part 11122 cuts the material again. The second cutting member 113 can cut the material in the second direction Y in the third part 11122 to further reduce the size of the material.

[0065] It is worth mentioning that the first direction X and the second direction Y intersect, that is, the cutting directions of the first cutting member 112 and the second cutting member 113 for the material are different, so as to be able to perform more precise shearing and cutting on the material, cut the size of the material smaller, and thus can improve the subsequent copper dissolution rate.

[0066] The material after cutting is discharged into the stirring assembly 120 through the material outlet 1111 to dissolve the material. The stirring assembly 120 is connected to the housing 111. It includes a cuboid stirring bin 121 and a stirring member 122 disposed in the stirring bin 121. This stirring bin 121 corresponds to the material outlet 1111. The material after cutting is discharged into the stirring bin 121 through the material outlet 1111.

[0067] In the solution of this application, the first cutting member 112 and the second cutting member 113 cut the material in different directions to reduce the size of the material, so as to accelerate the subsequent dissolution rate of the material. In addition, after the first cutting member 112 and the second cutting member 113 perform fine shearing and pulverization on the material, it is directly put into the stirring bin 121 for stirring, without an external shearing structure and a transfer structure, optimizing the dissolution process of the material and saving costs.

[0068] In the embodiment of this application, the first direction X and the second direction Y are perpendicular to each other, the first direction X is the vertical direction; the second direction Y is the horizontal direction. That is, the first cutting member 112 can cut in the length or width direction of the material, and the second cutting member 113 can cut in the thickness direction of the material. By cutting the material in different directions, it is possible to more easily pulverize large pieces of material without an external shearing structure to shear the large pieces of material, reducing the shearing process and saving costs.

[0069] It is worth mentioning that the first cutting member 112 and the second cutting member 113 can be automatically cut or manually cut.

[0070] Among them, referring to Figure 2 As shown, the first cutting member 112 includes a first driving member 1120 and at least two cutting members 1121. The first driving member 1120 can drive the cutting members 1121 to rotate. At least two cutting members 1121 are arranged in sequence in the second direction Y, that is, at least two cutting members 1121 are arranged in sequence in the horizontal direction. A cutting opening for cutting the material is formed between adjacent cutting members 1121, and the material is cut in the first direction X through this cutting opening.

[0071] In the embodiment of this application, the cutting members 1121 correspond to the first driving member 1120 one by one, that is, the number of the first driving members 1120 is the same as the number of the cutting members 1121. The first cutting member 112 includes two first driving members 1120 and two cutting members 1121. The two first driving members 1120 are arranged outside the material channel 1112. The two cutting members 1121 are arranged side by side in the first section and are adjacent to each other. A cutting opening is formed between the two cutting members 1121, and there is a gap between the two cutting members 1121 and the inner wall of the material channel 1112 to ensure the cutting of the material.

[0072] In the embodiment of this application, referring to Figure 3As shown, each cutting member 1121 includes a rotating shaft 11210 and a cutting wheel 11211. The rotating shaft 11210 is rotatably connected to its corresponding first driving member 1120, and it can be rotatably connected to the first driving member 1120 through a coupling, gears or other means. A plurality of cutting wheels 11211 are provided in the axial direction of the rotating shaft 11210, and each cutting wheel 11211 is arranged at intervals from each other. The cutting wheels 11211 are used to cut the material in the first direction X.

[0073] It can be understood that, in order to cut the material, the rotating directions of the two cutting members 1121 are opposite, so as to ensure that the material can be squeezed and cut when passing through the cutting opening.

[0074] In addition, the cutting member 1121 and the inner wall of the first section can also form a cutting opening to ensure complete cutting of the material and make the material more pulverized.

[0075] It is worth mentioning that the number of the cutting wheels 11211 can be changed according to requirements. For example, 12 cutting wheels 11211 are provided on the rotating shaft 11210. The cutting wheels 11211 can be connected to the rotating shaft 11210 by snap fasteners or integrally formed, and the cutting wheels 11211 on different rotating shafts 11210 can be arranged oppositely, or can be inserted into the gaps between adjacent cutting wheels 11211.

[0076] In addition, the first driving member 1120 can be driven by a motor.

[0077] This cutting assembly 110 can include a second cutting member 113. The second cutting member 113 can perform a reciprocating motion at the third part 11122 of the material passage 1112 to cut the material and further reduce the size of the material. The cutting assembly 110 can also include two second cutting members 113 arranged oppositely. The cutting parts 1133 of the two cutting members 113 can perform a reciprocating motion at the third part 11122. When the two second cutting members 113 move relative to each other, the material can be cut.

[0078] In the embodiment of the present application, refer to Figure 2 or Figure 4 As shown, this cutting assembly 110 includes two second cutting members 113, and the two second cutting members 113 are arranged oppositely. The two second cutting members 113 arranged oppositely can perform a reciprocating motion in the second direction Y, and the two second cutting members 113 move in different directions in the second direction Y respectively. When the two second cutting members 113 move relative to each other, they can cut the material in the second direction Y.

[0079] In order to enable the second cutting member 113 to move reciprocally in the second direction Y, a chute 1113 is provided in the housing 111, at least a part of the second cutting member 113 is disposed in the chute 1113, and the second cutting member 113 can reciprocally slide in the chute 1113 to cut the material in the second direction Y.

[0080] In order to control the second cutting member 113 to perform a reciprocating motion in the chute 1113, a cylinder, a connecting rod or other structures can be used to drive the second cutting member 113 to perform a reciprocating motion in the chute 1113.

[0081] The second cutting member 113 includes a second driving member, a rotating portion 1131, a connecting portion 1132 and a cutting portion 1133.

[0082] See Figure 4 As shown, the second driving member can adopt a motor structure. The rotating portion 1131 adopts a disc structure, which can be directly inserted on the rotating shaft of the second driving member. The rotating portion 1131 can perform a circular rotation at the same speed and in the same direction as the rotating shaft of the second driving member. There are protruding points on the rotating portion 1131, and one end of the connecting portion 1132 can be connected to the protruding points. The other end of the connecting portion 1132 is connected to the cutting portion 1133. The cutting portion 1133 is disposed in the chute 1113, and there is a protruding position on the cutting portion 1133, and the other end of the connecting portion 1132 is connected to the protruding position.

[0083] Among them, when the rotating portion 1131 performs a circular motion, the cutting portion 1133 can reciprocally slide in the chute 1113. When the two relatively arranged cutting portions 1133 slide in opposite directions, the material is cut in the second direction Y.

[0084] It should be noted that the connecting portion 1132 can adopt a hinge rod structure, and it is hingedly connected to both the rotating portion 1131 and the cutting portion 1133; the cutting portion 1133 can adopt a cutting knife.

[0085] The two relatively arranged cutting portions 1133 can continuously cut the material cut by the first cutting member 112, perform a transverse cut on the material, further reduce the size of the material, and improve the dissolution rate of the material.

[0086] After the first cutting member 112 vertically cuts the material and the second cutting member 113 horizontally cuts the material, the size of the cut material is reduced. And the cut material is directly put into the mixing bin 121, without the use of an external shearing structure and an external transfer structure, reducing the process and saving costs.

[0087] Among them, see Figure 2As shown, this stirring assembly 120 further includes a filter member 123. This filter member 123 is disposed within the stirring chamber 121. The filter member 123 and the stirring chamber 121 form a dissolution chamber 1210, and this dissolution chamber 1210 communicates with the material outlet 1111. That is, the material after being cut by the first cutting member 112 and the second cutting member 113 is introduced into this dissolution chamber 1210, the material is dissolved, and the filter member 123 can prevent the incompletely melted material from being discharged, ensuring the complete dissolution of the material and the purity of the copper sulfate solution.

[0088] In addition, in order to improve the dissolution rate of the material, this stirring member 122 is also disposed within this dissolution chamber 1210 to continuously stir the material and the solution by means of the stirring member 122 during the dissolution process, accelerating the dissolution of the material.

[0089] It can be understood that, referring to Figure 2 As shown, this stirring assembly 120 further includes a third driving member 124. The third driving member 124 can be a motor. This third driving member 124 is disposed at the outer bottom wall of the stirring chamber 121. The third driving member 124 is electrically connected to the stirring member 122, and the stirring member 122 can rotate following the third driving member 124 to stir the material and the dissolution liquid within the dissolution chamber 1210.

[0090] Referring to Figure 2 As shown, the stirring member 122 includes a stirring shaft 1220 and stirring rods 1221. This stirring shaft 1220 is connected to the third driving member 124, and the stirring rods 1221 can rotate at the same speed and in the same direction as the third driving member 124. A plurality of stirring rods 1221 are arranged at intervals in the axial direction of the stirring shaft 1220, and there is a gap between the stirring rods 1221 and the filter member 123 to prevent scratching the filter member 123. When the stirring shaft 1220 rotates, the stirring rods 1221 drive the material and the solution located within the dissolution chamber 1210 to come into full contact, improving the dissolution rate of the material.

[0091] In the embodiment of the present application, referring to Figure 2 As shown, this stirring assembly 120 further includes a liquid inlet pipe 125. One end of this liquid inlet pipe 125 is disposed within the dissolution chamber 1210, and it can be used to add a dissolution liquid, such as a sulfuric acid solution.

[0092] In the embodiment of the present application, referring to Figure 2As shown, the filter element 123 and the stirring chamber 121 also form a filtration chamber 1211, and this filtration chamber 1211 is arranged around the dissolution chamber 1210. That is, the filter element 123 and the inner side wall of the stirring chamber 121 form the filtration chamber 1211; the liquid filtered by the filter element 123 in the dissolution chamber 1210 flows into the filtration chamber 1211, and the filter element 123 is used to separate solids and liquids to ensure the dissolution degree of the material.

[0093] In the embodiment of the present application, as shown in Figure 2 As shown, the stirring chamber 121 includes a liquid inlet 1212, a liquid outlet 1213 and a slag discharge port 1214. The liquid inlet 1212 and the liquid outlet 1213 are both arranged on the outer side wall of the stirring chamber 121 and are located on the same side. The liquid inlet 1212 is communicated with the other end of the liquid inlet pipe 125, and the dissolution liquid is introduced into the liquid inlet pipe 125 through the liquid inlet 1212, that is, the dissolution liquid is introduced into the dissolution chamber 1210 through the liquid inlet 1212 and the liquid inlet pipe 125. The liquid outlet 1213 is communicated with the filtration chamber 1211, and it is used to discharge the filtered liquid, that is, to discharge the copper sulfate solution from the stirring chamber 121 to facilitate the subsequent preparation of the raw foil. The slag discharge port 1214 is arranged at the outer bottom wall of the stirring chamber 121 and is communicated with the dissolution chamber 1210 to facilitate the discharge of the residue in the dissolution chamber 1210 and ensure the cleanliness of the dissolution chamber 1210.

[0094] In the embodiment of the present application, as shown in Figure 2 and Figure 4 As shown, the cutting and dissolving device 100 further includes a baffle assembly 130, which includes a fourth driving member 131, a receiving groove 132 and a partition plate 133.

The partition plate 133 can gradually extend from the receiving groove 132 to the material outlet 1111 under the drive of the fourth driving member 131 to block the material outlet 1111 to avoid the problem of reduced dissolution rate caused by excessive addition of materials, and can add the cut materials according to the dissolution rate; the partition plate 133 can also be retracted from the side of the material outlet 1111 into the receiving groove 132 under the drive of the fourth driving member 131 to open the material outlet 1111.

[0095] It can be understood that this partition plate 133 can prevent the material from falling into the stirring chamber 121. Before dissolution, the material is first put into the stirring chamber 121, and then the dissolution liquid is introduced into the dissolution chamber 1210 to avoid the dissolution liquid splashing out when the material falls into the stirring chamber 121.

[0096] With this cutting and dissolving device 100, this solution can finely shear and crush the materials, avoid using an external shearing structure to shear and crush the materials, and optimize the copper dissolving process. Moreover, the materials after shearing and crushing are directly fed into the stirring bin 121 for dissolving, reducing the dissolving process, saving costs, and improving the copper dissolving efficiency.
