[0053] A stirring tank 1 is provided with a lifting unit, a stirring unit and a stirring control unit. The lifting unit is used to drive the stirring unit to move in a vertical direction. The stirring unit spirally rotates around a stirring shaft 2. The stirring control unit controls the rotation mode of the stirring unit according to the type and amount of tailings and additives. A cleaning component is provided on the outside of the stirring unit, and the cleaning component is in contact with the inner wall of the stirring tank 1.

[0054] The working principle and beneficial effects of the present invention are:

[0055] The present embodiment provides an energy-saving tailings sand mixing equipment. When the equipment is in use, the sealing cover 3 blocks the discharge port at the bottom of the mixing tank 1; a preset amount of tailings raw materials is added from the feed port at the top of the mixing tank 1; then the rotary stirring unit is started, and the stirring control unit adjusts the rotation mode of the rotary stirring unit according to the type and amount of tailings and additives, so that the tailings raw materials are stirred at the corresponding stirring speed and time. Under the action of the rotating force, the material is constantly turned and sheared, so that various additives, binders, etc. are fully in contact with the tailings particles; during the stirring process, the cleaning component on the outside of the rotary stirring unit acts synchronously, and uses the friction between itself and the tank wall to scrape off the attached material, so that it returns to the stirring body to participate in the mixing; when the stirring is completed, the lifting unit is started to separate the sealing cover 3 from the discharge port of the mixing tank 1, and the finished material is discharged through the gap between the mixing tank 1 and the sealing cover 3, and at the same time, the cleaning component descends to scrape off the material attached to the mixing tank 1 and discharge it; the top of the sealing cover 3 is set to a cone, and the material can be discharged along the cone surface, reducing the material residue in the mixing tank 1.

[0056] Through the above-mentioned structural design, a stirring tank 1 with an opening at the bottom is adopted, and a rotary stirring unit is arranged in the stirring tank 1 to stir the tailings material. The stirring control unit adjusts the rotation mode of the rotary stirring unit according to the types and amounts of tailings and additives in different tailings finished products, so that tailings and additives of different particle sizes and components can be quickly and evenly distributed in the mixture and discharged through the bottom discharge port; on the one hand, a cleaning component is integrated on the rotary stirring unit, and in conjunction with the bottom discharge port, it can ensure that the material is fully discharged without turning over the stirring tank 1, saving materials and power energy and facilitating control; on the other hand, the material attached to the stirring tank 1 is cleaned and remixed during the rotation and lifting process. Compared with the cleaning method during discharge, the cleaning efficiency is high, and the problem of difficult cleaning of stubborn attachments is effectively avoided.

[0057] Embodiment 2:

[0058] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1, the stirring control unit includes a tailings stirring database, in which a variety of tailings finished product information, the types and amounts of tailings and additives corresponding to the tailings finished products, and the rotation mode data adapted to the tailings finished products are recorded, and the rotation mode data specifically includes the rotation speed, rotation time and rotation segmentation process of the rotary stirring unit;

[0059] The finished tailings to be produced are input through the control panel, and the controller automatically matches the type and amount of the corresponding tailings and additives, and controls the metering pump to add the tailings and additives into the mixing tank 1; the controller automatically matches the rotation mode data and controls the action of the rotary stirring unit.

[0060] The working principle and beneficial effects of the above technical solution are:

[0061] The mixing control unit builds a tailings mixing database in the controller, and enters the types and amounts of tailings and additives corresponding to various tailings finished products, as well as the rotation mode data suitable for the tailings finished products; the types and amounts of tailings and additives are set according to the tailings batching; the rotation mode data suitable for the tailings finished products is determined by the staff based on experience or related mixing tests; the rotation mode data includes the rotation speed, rotation time and rotation segmentation process, such as the segmentation process of high-speed dispersion in the early stage, medium-speed mixing in the middle stage, and low-speed fusion in the late stage. The operator enters the tailings finished product data through the control panel, and can realize automatic control of the feeding process and the mixing process through data matching. The mixing process can be adjusted to adapt to the differences between finished products and raw materials, so as to achieve an ideal mixing effect and solve the problems of poor mixing effect and energy waste during continuous high-speed mixing.

[0062] Embodiment 3:

[0063] like Figure 1 As shown, based on the above-mentioned embodiment 1, the energy-saving tailings sand mixing equipment also includes: an electric clamp 4, which is connected to the bottom end of the mixing tank 1 and is evenly arranged around the discharge port, and the electric clamp 4 is used to clamp the sealing cover 3 on the discharge port.

[0064] The working principle and beneficial effects of the above technical solution are:

[0065] When performing the mixing operation, the electric clamp 4 is rotated to clamp the sealing cover 3 so that it is sealed with the discharge port at the bottom of the mixing tank 1 to prevent the material from leaking out; when performing the discharging operation, the electric clamp 4 is rotated to separate from the sealing cover 3 so that the sealing cover 3 can fall freely.

[0066] Embodiment 4:

[0067] like Figure 1-Figure 6 As shown, based on the above embodiment 3, the lifting unit includes:

[0068] A supporting platform 11, the supporting platform 11 is connected to the top of the mixing tank 1;

[0069] A lifting column 12, wherein the lifting column 12 is slidably connected to the center of the supporting platform 11, and the bottom end of the lifting column 12 extends into the mixing tank 1 and is connected to the mixing shaft 2, a rack is provided on the side of the lifting column 12, and the lifting column 12 is hollow;

[0070] The lifting drive gear 13 is evenly arranged on the outside of the lifting column 12, and the lifting drive gear 13 is meshed with the rack. The lifting drive gear 13 is rotatably arranged on the supporting platform 11, and the gear shaft of the lifting drive gear 13 is connected to the lifting drive motor.

[0071] The working principle and beneficial effects of the above technical solution are:

[0072] When discharging, the lifting drive motor is started to rotate forward, and the lifting drive motor drives the lifting drive gear 13 to rotate. Multiple lifting drive gears 13 are evenly distributed on the outside of the lifting column 12, and mesh with the rack on the side of the lifting column 12 to make the lifting column 12 move linearly downward along the center of the support platform 11, and then drive the sealing cover 3 downward through the stirring shaft 2 to open the discharge port of the mixing tank 1. When the discharging is completed, the lifting drive motor is started to reverse, so that the stirring shaft 2 and the sealing cover 3 move upward, and the discharge port of the mixing tank 1 is blocked.

[0073] Embodiment 5:

[0074] like Figure 1-Figure 6 As shown, on the basis of the above-mentioned embodiment 4, a plurality of guide rods 6 are connected to the top end of the sealing cover 3, a plurality of guide holes 5 are provided at the bottom end of the stirring tank 1, and the guide rods 6 are slidably connected in the guide holes 5.

[0075] The working principle and beneficial effects of the above technical solution are:

[0076] The guide rod 6 is slidably disposed in the guide hole 5 to guide the movement of the sealing cover 3 so that the sealing cover 3 can only move up and down in the vertical direction.

[0077] Embodiment 6:

[0078] like Figure 1-Figure 6 As shown, on the basis of the above-mentioned embodiment 4, the top end of the stirring shaft 2 is rotatably connected to the cavity of the lifting column 12, and a limit plate 14 is horizontally arranged on the stirring shaft 2, and the limit plate 14 is used to limit the vertical position of the stirring shaft 2 and the lifting column 12; the rotary stirring motor 15 is installed in the lifting column 12 and connected to the top end of the stirring shaft 2; the electric roller 8 is installed at the top end of the lifting column 12, and a rope 9 is wound around the electric roller 8, and the rope 9 extends into the lifting column 12.

[0079] Two groups of spiral grooves 16 with opposite rotation directions are arranged on the stirring shaft 2, and the top ends and bottom ends of the two groups of spiral grooves 16 are connected.

[0080] A rotating sleeve 17 is sleeved on the stirring shaft 2, a shock-absorbing block is connected to the top of the rotating sleeve 17, the top of the rotating sleeve 17 is connected to the rope 9, a plurality of stirring plate assemblies are connected to the rotating sleeve 17 in the vertical direction, a cleaning assembly is connected to the outer end of the stirring plate assembly, a guide rod is connected to the inner wall of the rotating sleeve 17, and the guide rod is slidably connected to the spiral groove 16.

[0081] The working principle and beneficial effects of the above technical solution are:

[0082] The rotary stirring motor 15 is used to drive the stirring shaft 2 to rotate. When the stirring shaft 2 rotates, the limit plate 14 is driven to rotate in the lifting column 12, and the limit plate 14 can limit the vertical position of the stirring shaft 2 and the lifting column 12; so that the stirring shaft 2 is synchronously lifted and lowered with the lifting column 12. When the rotary stirring motor 15 drives the stirring shaft 2 to rotate, the stirring shaft 2 drives the stirring plate assembly thereon to rotate, and the materials in the stirring tank 1 are uniformly stirred. The electric roller 8 is in a locked state, and the length of the rope 9 remains unchanged, so that the stirring plate assembly is concentratedly stirred at the upper part of the stirring tank 1. Since the length of the rope 9 remains unchanged, the guide rod on the rotating sleeve 17 cooperates with the spiral groove 16 but does not slide, ensuring that the rotating sleeve 17 and the stirring shaft 2 rotate synchronously.

[0083] When the stirring is completed and the material is discharged, the stirring motor 15 stops rotating and the stirring shaft 2 does not rotate; at the same time, the electric roller 8 is unlocked and can rotate forward, and the rope 9 can extend freely. During the discharge, the stirring plate assembly automatically descends under the action of the gravity of the material and the gravity of the rotating sleeve 17 and the stirring plate assembly. During the descent, the guide rod on the rotating sleeve 17 slides along the spiral groove 16, causing the stirring plate assembly to fall in a spiral motion, thereby scraping off the material attached to the inner wall of the stirring tank 1, so as to facilitate the full discharge of the material.

[0084] When the discharge is completed, the motorized roller 8 is driven to reverse, the rope 9 is wound and shortened, the rotating sleeve 17 is pulled to slide upward in a spiral, and the stirring plate assembly moves upward in a spiral motion until it is reset.

[0085] Through the above-mentioned structural design, when the tailings are discharged after stirring, the stirring plate assembly and the cleaning assembly are driven to move under the action of material pressure and dead weight, and the attachments on the inner wall of the stirring tank 1 are automatically scraped off without turning over the stirring tank 1, thereby reducing the difficulty of equipment control, and the cleaning process is synchronized with the discharging process, thereby improving the tailings discharging efficiency; the spiral paths of the cleaning assembly during the rising and falling processes are different, which can reduce cleaning dead corners.

[0086] Embodiment 7:

[0087] like Figure 1-Figure 6 As shown, based on the above embodiment 6, the stirring plate assembly includes:

[0088] A stirring plate 18, one end of which is hinged to the rotating sleeve 17, and the other end of which extends toward the side wall of the stirring tank 1. The length of the stirring plate 18 is greater than the radius of the cavity of the stirring tank 1, and the outer end of the stirring plate 18 is inclined upward relative to the inner end; a plurality of stirring plates 18 are evenly arranged along the circumferential direction of the rotating sleeve 17;

[0089] The damping member 19 is supported and arranged between the top of the stirring plate 18 and the rotating sleeve 17. Under the action of the damping member 19, the stirring plate 18 has a tendency to rotate downward. The damping of the damping member 19 is adjustable.

[0090] The working principle and beneficial effects of the above technical solution are:

[0091] Under the action of the damping member 19, the stirring plate 18 can maintain a downward rotation trend, so that the cleaning component outside the stirring plate 18 maintains sufficient pressure on the inner wall of the stirring tank 1, so that it can fully scrape off the materials with strong adhesion, and the cleaning effect is better. By adjusting the components of the damping member 19, the pressure of the cleaning component on the inner wall of the stirring tank 1 can be adjusted to adapt to different material states.

[0092] Embodiment 8:

[0093] like Figure 1-Figure 6 As shown, on the basis of the above-mentioned embodiment 7, a blocking block 21 is provided at the top of the outer end of the stirring plate 18, and a counterweight ball 23 is connected to the bottom of the outer end of the stirring plate 18 through a pull rope 22.

[0094] The working principle and beneficial effects of the above technical solution are:

[0095] The blocking block 21 and the weighted ball 23 are arranged on the stirring plate 18, so that the scraped attached materials can be concentrated on the outside of the blocking block 21 during the cleaning process, increasing the gravity on the outside of the stirring plate 18, increasing the centrifugal force when the stirring plate 18 rotates, and making the rotation cleaning process smoother. At the same time, the blocking block 21 is arranged at the stirring plate 18, so that part of the materials can be blocked during the stirring process, changing the moving direction of the materials, reducing the concentration of the materials on the inner wall of the stirring tank 1, and thus reducing the adhesion of the materials.

[0096] Embodiment 9:

[0097] like Figure 4 , Figure 7-Figure 11 As shown, based on the above-mentioned embodiment 8, the cleaning component is connected to the outer end of the stirring plate 18, and the cleaning component includes:

[0098] A cleaning ring 31, the cleaning ring 31 is connected to the end of the stirring plate 18 through a bracket 30; the cleaning ring 31 includes a central hole 32, a connecting hole 33 and a guide groove 34, the central hole 32 is arranged at the center of the cleaning ring 31, and four connecting holes 33 are evenly arranged on the cleaning ring 31 and arranged around the central hole 32;

[0099] A rotating shaft 35, the rotating shaft 35 is rotatably connected to the center hole 32, and one end of the rotating shaft 35 extends into the stirring plate 18 and is connected to the cleaning drive motor;

[0100] A cleaning end 36, one end of which is connected to the rotating shaft 35, and the other end is set as a conical end and connected to the inner wall of the stirring tank 1; a plurality of connecting grooves 37 are evenly arranged on the cleaning end 36, and the extending direction of the connecting grooves 37 is consistent with the extending direction of the connecting hole 33.

[0101] The working principle and beneficial effects of the above technical solution are:

[0102] When the cleaning assembly is in use, as the stirring plate 18 rotates, the cleaning end 36 contacts the inner wall of the stirring tank 1; the end of the cleaning end 36 can be connected to the cleaning plate to increase the cleaning area; most of the cleaned materials fall directly, and some of the materials adhere together after being attached, and accumulate on the cleaning end 36 as they are cleaned; the old materials enter the connecting hole 33 of the cleaning ring 31 through the connecting groove 37 of the cleaning end 36, and are discharged from the inner side of the cleaning ring 31; by starting the cleaning drive motor, the cleaning drive motor drives the cleaning end 36 to rotate, so that the connecting area between the connecting groove 17 of the cleaning end 26 and the connecting hole 33 changes, and the material adhesion that enters is chopped up, so that it can be better dispersed and mixed with the material in the stirring tank 1. Through the above-mentioned structural design, the problem that the material adhesion under cleaning is attached to the cleaning end 36 and cannot fall down is effectively solved, the sufficiency of the material is improved, and the material residue is reduced; at the same time, the material adhesion is chopped up and dispersed, which can prevent the material from falling back into the material in the form of adhesion, thereby improving the discharge quality.

[0103] Embodiment 10:

[0104] like Figure 7-Figure 11 As shown, on the basis of the above-mentioned embodiment 9, the cleaning ring 31 further includes a guide groove 34, which is arranged on a side of the cleaning ring 31 close to the mixing tank 1; the guide groove 34 includes a plurality of convex sections 38 and concave sections 39 arranged at intervals;

[0105] The side of the cleaning end 36 close to the cleaning ring 31 also includes a push rod 41, a guide ball 42, a sealing block 43 and a connecting rod 44. The push rod 41 is slidably connected to the cleaning end 36. Four push rods 41 are evenly arranged on the cleaning end 25, and the push rods 41 are located between adjacent connecting grooves 37. The sliding direction of the push rod 41 is along the diameter direction of the cleaning end 36; the guide ball 42 is connected to the end of the push rod 41, and the guide ball 42 is slidably connected to the guide groove 34; two sealing blocks 43 are slidably connected to the cleaning end 36, and the two sealing blocks 43 are symmetrically arranged on both sides of each push rod 41, and the sliding direction of the sealing blocks 43 is perpendicular to the sliding direction of the push rod 41. The cleaning end 36 is provided with a sliding groove adapted to the push rod 41 and the sealing block 43; the two ends of the connecting rod 44 are respectively hinged to the push rod 41 and the sealing block 43, and the end of the connecting rod 44 connected to the push rod 41 is inclined toward the center of the cleaning end 36.

[0106] The working principle and beneficial effects of the above technical solution are:

[0107] When the cleaning ring 31 rotates, it drives the push rod 41 to rotate synchronously, so that the guide ball 42 slides in the guide groove 34, ensuring the rotation balance of the cleaning ring 31; when the guide ball 42 slides to the convex section 38 of the guide groove 34, the cleaning assembly is in the first state, and the connecting groove 17 is staggered with the connecting hole 33; the guide ball 42 pulls the push rod 41 to move outward, and the push rod 41 drives the sealing blocks 43 on both sides to move toward the connecting groove 17 on both sides through the two connecting rods 44. The sealing blocks 43 are adapted to the curvature of the connecting hole 33, and then the connecting groove 17 and the connecting hole 33 are completely separated, thereby improving the cutting effect of the material adhesion. When the guide ball 42 slides to the concave section 39 of the guide groove 34, the cleaning assembly is in the second state, and the connecting groove 17 is opposite to the connecting hole 33; the guide ball 42 pushes the push rod 41 to move inward, and the push rod 41 pulls the sealing blocks 43 on both sides to approach through the two connecting rods 44, expanding the connecting area between the connecting groove 17 and the connecting hole 33 on both sides, so that the material can pass better.
