Description

Technical Field

[0001] This utility model relates to the field of mineral processing and reagent preparation technology, and in particular to a circulating stirring reagent preparation device for mineral processing. Background Technology

[0002] A circulating stirring reagent preparation device is a piece of equipment used in mineral processing to prepare flotation reagent solutions. Its main function is to accelerate reagent dissolution and improve the accuracy and uniformity of reagent preparation.

[0003] The circulating stirring and mixing device for mineral processing disclosed in Chinese Patent Publication No. CN223127783U, through the operation of a drive motor, causes a rotating shaft to drive a first stirring rod and a second stirring rod to rotate, thereby stirring different solid and liquid reagents to achieve uniform mixing; however, according to circulating stirring and mixing devices provided in related fields and existing technologies:

[0004] Firstly, when the existing stirring rod rotates, the material tends to form a follow flow, and the material at the bottom and around the rod cannot circulate upwards, resulting in insufficient exchange with other areas of the cylinder. This leads to local clumping and poor mixing uniformity, which not only prolongs the preparation time but also causes waste due to the loss of undissolved agents, and also causes fluctuations in the preparation concentration.

[0005] Secondly, the impurities brushed off during cleaning will fall directly back into the material below the filter screen, making it impossible to completely separate them. This results in impurities still being mixed in with the finished medicine, affecting the quality of the medicine. Furthermore, undissolved clumps or impurities are scattered on the surface of the filter screen, making it difficult to collect and discharge them quickly. They are likely to remain and contaminate the next medicine preparation. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a circulating stirring and mixing device for mineral processing.

[0007] The objective of this utility model is achieved through the following technical solution: a circulating stirring and mixing device for mineral processing, comprising a mixing cylinder, a stirring rod, and an automatic flow guiding component for guiding the material around the bottom of the stirring rod upwards. A self-cleaning filter component is provided near the bottom of the stirring rod. The automatic flow guiding component includes a pipe fixedly installed on the outer surface of the stirring rod. The pipe is L-shaped, with an elastic rolling assembly at the upper opening and a flow guiding component at the lower opening. An elastic tube is provided inside the pipe to connect the elastic rolling assembly and the flow guiding component. A liquid outlet is provided on the side of the pipe near the elastic rolling assembly. The inner wall of the mixing cylinder has multiple protrusions. The elastic rolling assembly, in conjunction with the multiple protrusions, allows the elastic tube to control the extension and retraction of the flow guiding component.

[0008] Preferably, the elastic rolling assembly includes a rod slidably disposed inside the pipe, a roller rotatably disposed at one end of the rod outside the pipe, the roller being horizontally disposed, a support ring fixedly disposed on the outer surface of the rod outside the pipe, a sleeve fitted on the outer surface of the support ring, the sleeve being fixedly connected to the pipe, an elastic element installed inside the sleeve, and the end of the elastic element away from the sleeve being in contact with the support ring.

[0009] Preferably, the flow guiding assembly includes a plug that fits into the opening of the pipe, and a cone is fixedly provided at the bottom of the plug.

[0010] Preferably, the elastic tube is a flexible spring tube, the outer surface of the elastic tube is in contact with the inner wall of the pipe, and the insertion rod and the plug are both connected to the elastic tube through multiple connecting rods.

[0011] Preferably, the cross-section of the protrusion is arc-shaped, and multiple protrusions are distributed at equal intervals on the inner wall of the drug mixing cylinder.

[0012] Preferably, the self-cleaning filter assembly includes a filter screen rotatably mounted on the outer surface of the stirring rod. The filter screen is inserted into the inner wall of the mixing cylinder. The stirring rod is fixedly provided with multiple cleaning brushes below the filter screen, and the bristles of the multiple cleaning brushes are in close contact with the filter screen. A blind hole is provided at the center of the stirring rod, with the opening of the blind hole facing downwards. A groove is provided at the center of the stirring rod above the filter screen, and the groove communicates with the blind hole. A sealing plug is inserted into the blind hole.

[0013] Preferably, the filter screen is a conical screen, and the inner wall of the drug mixing cylinder is provided with multiple support blocks corresponding to the position of the filter screen, and the filter screen is provided with locking grooves corresponding to the positions of the multiple support blocks.

[0014] Preferably, the bottom of the drug mixing cylinder is provided with a drain pipe, the top of the drug mixing cylinder is fixedly installed with a top cover, the center of the top cover is provided with a drive mechanism for controlling the rotation of the stirring rod, and the top of the top cover is provided with a liquid inlet pipe.

[0015] The beneficial effects of this circulating stirring and mixing device for mineral processing are as follows: Firstly, by setting up an automatic flow guide component and a self-cleaning filter component, it achieves the effect of pushing the sediment around the stirring rod upward, breaking the inertia of the following flow, and forcing the material to form an up-and-down convection circulation in the cylinder. Due to the improved efficiency of material circulation and exchange, not only is the mixing time shortened, but also the waste of reagents caused by insufficient dissolution is reduced. Secondly, the filter screen can effectively intercept incompletely dissolved solid particles or other impurities, ensuring the high purity of the discharged reagent solution. At the same time, the presence of the cleaning brush prevents impurities from accumulating below the filter screen or flowing out with the reagent solution, further ensuring the quality of the material. Thirdly, substandard materials can be discharged in a concentrated manner, avoiding contamination or affecting the concentration of the next mixing. Attached Figure Description

[0028] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0029] like Figures 1 to 9 As shown, a circulating stirring and mixing device for mineral processing includes a mixing cylinder 1, a stirring rod 2, and an automatic flow guiding component for guiding the material around the bottom of the stirring rod 2 upwards. A self-cleaning filter component is provided near the bottom of the stirring rod 2. The automatic flow guiding component includes a pipe 3 fixedly installed on the outer surface of the stirring rod 2. The pipe 3 is L-shaped, with an elastic rolling component 4 at the upper opening and a flow guiding component 5 at the lower opening. An elastic tube 6 is provided inside the pipe 3 to connect the elastic rolling component 4 and the flow guiding component 5. A liquid outlet 301 is provided on the side of the pipe 3 near the elastic rolling component 4. The inner wall of the mixing cylinder 1 is provided with multiple protrusions 7, such as... Figure 3 and Figure 4 As shown, the cross-section of the protrusion 7 is arc-shaped, and multiple protrusions 7 are evenly distributed on the inner wall of the drug mixing cylinder 1. By utilizing the cooperation between the elastic rolling assembly 4 and the multiple protrusions 7, the elastic tube 6 can control the flow guiding assembly 5 to extend and retract. The bottom of the drug mixing cylinder 1 is provided with a drain pipe 101, and the top of the drug mixing cylinder 1 is fixedly installed with a top cover 12. The center of the top cover 12 is provided with a drive mechanism 13 for controlling the rotation of the stirring rod 2, and the top of the top cover 12 is provided with a liquid inlet pipe 14.

[0030] like Figure 9As shown, the elastic rolling assembly 4 includes an insert rod 401 slidably disposed inside the pipe 3. A roller 402 is rotatably disposed at one end of the insert rod 401 located outside the pipe 3. The roller 402 is horizontally disposed. A support ring 403 is fixedly disposed on the outer surface of the insert rod 401 located outside the pipe 3. A sleeve 404 is fitted on the outer surface of the support ring 403. The sleeve 404 is fixedly connected to the pipe 3. An elastic element 405 is installed inside the sleeve 404. The end of the elastic element 405 away from the sleeve 404 is in contact with the support ring 403.

[0031] like Figure 9 As shown, the flow guiding component 5 includes a plug 501 that fits into the opening of the pipe 3, and a cone 502 is fixedly provided at the bottom of the plug 501; the elastic tube 6 is a flexible spring tube, and the outer surface of the elastic tube 6 fits into the inner wall of the pipe 3. The insertion rod 401 and the plug 501 are both connected to the elastic tube 6 through multiple connecting rods 601. The multiple connecting rods 601 form a railing-like structure, which can prevent large particles from entering the elastic tube 6; Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, when the roller 402 contacts the protrusion 7, the protrusion 7 causes the roller 402 to drive the insertion rod 401 to move towards the pipe 3, so that the multiple connecting rods 601 at the end of the insertion rod 401 push the elastic tube 6 towards the lower opening of the pipe 3. Thus, the elastic tube 6 causes the plug 501 to move away from the pipe 3. When the roller 402 separates from the protrusion 7, the elastic force of the elastic element 405 is restored, so that the support ring 403 drives the insertion rod 401 and the roller 402 to move away from the pipe 3. Thus, the multiple connecting rods 601 at the end of the insertion rod 401 pull the elastic tube 6 towards the upper opening of the pipe 3. At this time, the elastic tube 6 causes the plug 501 to move towards the pipe 3. When the plug 501 moves towards the pipe 3, the plug 501 can push the material around the bottom of the stirring rod 2 into the elastic tube 6. Then the material inside the elastic tube 6 will be discharged through the liquid outlet 301 on the pipe 3.

[0032] In summary, through the cooperation of the automatic flow guiding component and the protrusion 7, the stirring rod 2 can actively guide the material below upward when it rotates, fundamentally solving the problems of material following the flow and local agglomeration in traditional stirring. This makes the material circulation and exchange in the mixing cylinder 1 more thorough, and the overall mixing uniformity is greatly improved, thereby ensuring the consistency and stability of the reagent concentration. This provides a high-quality reagent base for subsequent flotation processes. Due to the improved efficiency of material circulation and exchange, especially the effective lifting and stirring of the bottom material, the dissolution rate of solid reagents is accelerated, which not only shortens the reagent preparation time but also reduces reagent waste caused by insufficient dissolution, indirectly reducing production costs.

[0033] like Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the self-cleaning filter assembly includes a filter screen 8 rotatably mounted on the outer surface of the stirring rod 2. The filter screen 8 is inserted into the inner wall of the mixing cylinder 1. Multiple cleaning brushes 9 are fixedly mounted on the stirring rod 2 below the filter screen 8, with the bristles of each brush adhering to the filter screen 8. A blind hole 201 is opened at the center of the stirring rod 2, with the opening facing downwards. A groove 202 is opened at the center of the stirring rod 2 above the filter screen 8, communicating with the blind hole 201. A sealing plug 10 is inserted into the blind hole 201. The filter screen 8 is a conical mesh. Utilizing the characteristics of the conical filter screen 8, substandard materials will concentrate at the center of the filter screen 8 under gravity. Then, the operator pulls out the sealing plug 10, allowing the substandard materials to enter the blind hole 201 of the stirring rod 2 through the groove 202 for centralized discharge, preventing contamination or affecting the concentration of the next batch of medicine, and further improving the... The accuracy of drug dispensing is improved. Multiple support blocks 11 are fixedly provided on the inner wall of the drug mixing cylinder 1 at the position corresponding to the filter screen 8. The filter screen 8 is provided with locking grooves 801 at the positions corresponding to the multiple support blocks 11. The cooperation between the multiple support blocks 11 and the multiple locking grooves 801 can prevent the filter screen 8 from rotating with the stirring rod 2, thereby ensuring the stability of the filter screen 8 during use. At the same time, the filter screen 8 is provided with a rotation hole (not labeled in the figure) at the position corresponding to the stirring rod 2. The stirring rod 2 is connected to the above-mentioned rotation hole through a bearing (not labeled in the figure). The bearing can reduce the friction between the stirring rod 2 and the filter screen 8, and allow the stirring rod 2 to drive the filter screen 8 to move. When the upper cover 12 is separated from the drug mixing cylinder 1, the stirring rod 2 can take the filter screen 8 out, which makes it convenient to clean the stirring rod 2, the filter screen 8, the self-cleaning filter assembly and the drug mixing cylinder 1 separately.

[0034] In summary, when the stirring rod 2 rotates, it drives the cleaning brush 9 to rotate synchronously, continuously cleaning the filter screen 8, effectively preventing the filter screen 8 from clogging, ensuring that the filtered material can be smoothly discharged through the drain pipe 101, avoiding downtime for cleaning due to blockage, ensuring the continuity of production, and during unblocking, the impurities trapped inside the mesh will be discharged upwards instead of being pressed down below the filter screen 8, thereby further improving the purity of the discharged drug solution.

[0035] The work process is as follows:

[0036] S1: As Figure 1 and Figure 2 As shown, during use, the material can be injected into the mixing cylinder 1 through the liquid inlet pipe 14, and then the stirring rod 2 can be rotated by the drive mechanism 13 to mix and stir the material.

[0037] S2: As Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, when the stirring rod 2 rotates, the roller 402 at the upper opening of the pipe 3 will contact the protrusion 7. Then, the protrusion 7 will cause the roller 402 to drive the insertion rod 401 to move towards the pipe 3. This causes the multiple connecting rods 601 at the end of the insertion rod 401 to push the elastic tube 6 towards the lower opening of the pipe 3. As a result, the elastic tube 6 will cause the plug 501 to move away from the pipe 3 (at this time, the elastic element 405 will be compressed by the support ring 403).

[0038] S3: As Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, when the roller 402 separates from the protrusion 7, the elastic force of the elastic element 405 is restored, thereby causing the support ring 403 to drive the insertion rod 401 and the roller 402 to move away from the pipe 3, so that the multiple connecting rods 601 at the end of the insertion rod 401 pull the elastic tube 6 to move towards the upper opening of the pipe 3. At this time, the elastic tube 6 will cause the plug 501 to move towards the pipe 3.

[0039] S4: As Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, when the plug 501 moves toward the pipe 3, the plug 501 can push the material around the bottom of the stirring rod 2 into the elastic tube 6, and then the material inside the elastic tube 6 will be discharged through the liquid outlet 301 on the pipe 3.

[0040] S5: In summary, as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, when the stirring rod 2 rotates, multiple protrusions 7 sequentially trigger the elastic rolling assembly 4, driving the flow guiding assembly 5 to reciprocate and extend. The sediment material around the bottom of the stirring rod 2 is pushed upward, breaking the inertia of following the flow and forcing the material to form an up-and-down convection circulation in the cylinder. Due to the improved efficiency of material circulation and exchange, especially the effective lifting and stirring of the bottom material, the dissolution rate of solid agents is accelerated, which not only shortens the preparation time but also reduces the waste of agents caused by insufficient dissolution, indirectly reducing production costs.

[0041] S6: As Figure 2As shown, the material is screened by the filter screen 8, which can effectively intercept incompletely dissolved solid particles or other impurities, ensuring that the discharged drug solution has high purity. Materials that meet the standards can pass through the filter screen 8 and reach the bottom of the filter screen 8, and then be discharged through the drain pipe 101.

[0042] S7: As Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, when the stirring rod 2 rotates, it drives the cleaning brush 9 to rotate synchronously, continuously cleaning the filter screen 8, effectively preventing the filter screen 8 from clogging, ensuring that the filtered material can be smoothly discharged through the drain pipe 101, avoiding downtime for cleaning due to clogging, and ensuring the continuity of production.

[0043] S8: As Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, when the equipment stops operating, the non-compliant materials will be concentrated in the center of the filter screen 8 under the action of gravity, thanks to the characteristics of the conical filter screen 8. Then the operator pulls out the sealing plug 10, allowing the non-compliant materials to enter the blind hole 201 of the stirring rod 2 through the slot 202 for centralized discharge, thus avoiding contamination or affecting the concentration of the next batch of medicines and further improving the accuracy of medicine preparation.

[0044] The mixing cylinder 1, stirring rod 2, and driving mechanism 13 described in this application are all known technologies in this field, and therefore their specific structures and working principles are not described in detail.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
