Description
Technical Field
[0001] This utility model relates to the field of mine backfill slurry technology, and more specifically, to a high-efficiency preparation device for mine backfill slurry. Background Technology
[0002] Mine backfill slurry is a material used to fill the goaf in underground mines. Its purpose is to control surface subsidence, improve mine safety, and treat tailings and other waste. This slurry is typically composed of a mixture of multiple components. Therefore, a mixing device is required to mix and stir the various raw materials during the preparation of mine backfill slurry.
[0003] However, existing mixing equipment for mine backfill slurry often uses a one-time feeding method, which can easily lead to poor mixing effect and blockage problems. In addition, the mixing process often uses a single stirring method, which affects the mixing effect of the materials in the mixing tank. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose an efficient preparation device for mine filling slurry.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A high-efficiency preparation device for mine backfill slurry includes a mounting frame, a mixing tank, a conveying auger, a baffle assembly, a rotating assembly, a reciprocating assembly, and a stirring rod. The mounting frame houses the mixing tank, which has an inlet and a outlet. The inlet is connected to the outlet end of the conveying auger located outside the mixing tank. The outlet is connected to the baffle assembly located at the bottom of the mixing tank. The mixing tank contains a rotating assembly, which is connected to the stirring rod via the reciprocating assembly, so that the stirring rod performs a reciprocating lifting motion while rotating.
[0007] Furthermore, the above solution includes a support, a telescopic cylinder, a sliding rod, a mounting plate, and a baffle plate. The support is mounted on a mounting frame and has a telescopic cylinder fixed horizontally on it and a sliding rod slidably mounted thereon. The ends of the telescopic cylinder and the sliding rod are connected to the mounting plate. A baffle plate is horizontally mounted on the mounting plate. The baffle plate is located below the mixing tank and has a discharge port that matches the discharge port. When the discharge port corresponds to the discharge port, the discharge port is open. When the discharge port and the discharge port are staggered, the discharge port is closed.
[0008] Furthermore, the above solution includes two discharge ports and two unloading ports.
[0009] Furthermore, the above-mentioned scheme includes an upper rotating roller, a lower rotating roller, an upper connecting plate, a lower connecting plate, and a drive motor; the upper rotating roller and the lower rotating roller are respectively vertically rotatably arranged at the top and bottom of the mixing tank, and one end of the upper rotating roller and the lower rotating roller are connected to the upper connecting plate and the lower connecting plate, respectively, and the other end of the upper rotating roller extends to the outside of the mixing tank and is connected to the drive motor, and the reciprocating assembly is arranged between the upper connecting plate and the lower connecting plate.
[0010] Furthermore, the above solution includes a lead screw, a guide rod, a servo motor, a limiter, and a movable seat; the lead screw and the guide rod are both vertically arranged between the upper connecting plate and the lower connecting plate, and the top of the lead screw is connected to the servo motor, and the movable seat is fitted together on the lead screw and the guide rod. The guide rod is also provided with a limiter for limiting the vertical position of the movable seat, and the stirring rod is circumferentially arranged on the movable seat.
[0011] Furthermore, the above scheme provides a boss and a feeding platform at the bottom of the mixing tank, so that two conical spaces are formed at the bottom of the mixing tank to facilitate material discharge, and two discharge ports are respectively set at the positions of the two conical spaces.
[0012] Furthermore, the above solution includes two U-shaped frames connected to the upper and lower connecting plates. The two U-shaped frames are symmetrically arranged and located outside the stirring rod, so that the upper and lower connecting plates rotate simultaneously, thereby realizing the mixing action of the materials in the mixing tank.
[0013] Furthermore, the above solution includes a rubber scraper on the outside of the U-shaped frame, which contacts the inner wall of the mixing tank to reduce the adhesion of material to the inner wall of the mixing tank.
[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0022] See attached document Figure 1 and attached Figure 2 As shown, a high-efficiency preparation device for mine backfill slurry includes a mounting frame 1, a mixing tank 2, a conveying auger 3, a baffle assembly 4, a rotating assembly 5, a reciprocating assembly 6, and a stirring rod 7. The mounting frame 1 houses the mixing tank 2, which has an inlet 21 and a outlet 22. The inlet 21 is connected to the outlet end of the conveying auger 3 located outside the mixing tank 2, allowing the conveying auger 3 to feed materials into the mixing tank 2. The outlet 22 is connected to the baffle assembly 4 located at the bottom of the mixing tank 2, allowing the baffle assembly 4 to block and open the mixing tank 2 during material discharge. The rotating assembly 5 is installed inside the mixing tank 2, and the rotating assembly 5 is connected to the stirring rod 7 via the reciprocating assembly 6, so that the stirring rod 7 performs a reciprocating lifting motion while rotating.
[0023] In the specific implementation of this utility model, the material is fed through the conveying auger 3. During this process, the material undergoes preliminary mixing, while avoiding blockage problems caused during feeding and improving the feeding effect when the material enters the mixing tank 2. When preparing the mine filling slurry, the stirring rod 7 can rotate under the action of the rotating component 5. With the action of the reciprocating component 6, the stirring rod 7 rotates and reciprocates in the mixing tank 2. This multi-directional mixing method ensures that the material is fully mixed in all positions in the mixing tank 2. By adding up-and-down reciprocating motion during rotation, the area in the mixing tank 2 can be effectively stirred, allowing most of the material to participate in the mixing process. Moreover, the up-and-down reciprocating motion allows materials of different densities, particle sizes, or viscosities to quickly exchange positions in a short time, thereby accelerating the diffusion rate, shortening the time required to achieve uniform mixing, and maintaining a highly efficient mixing effect.
[0024] Regarding the structure of the material-stopping component 4 in the above scheme, specifically, please refer to the attached document. Figure 1 As shown, the baffle assembly 4 includes a bracket 41, a telescopic cylinder 42, a sliding rod 43, a mounting plate 44, and a baffle plate 45. The bracket 41 is mounted on the mounting frame 1, and a telescopic cylinder 42 is horizontally fixed on it and a sliding rod 43 is slidably mounted on it. The ends of the telescopic cylinder 42 and the sliding rod 43 are connected to the mounting plate 44. A baffle plate 45 is horizontally mounted on the mounting plate 44. The baffle plate 45 is located below the mixing tank 2 and has a discharge port 451 that matches the discharge port 22. When the discharge port 451 corresponds to the discharge port 22, the discharge port 22 is open, which is the discharge state. When the discharge port 451 and the discharge port 22 are staggered, the discharge port 22 is closed, which is the mixing state.
[0025] The design of the baffle assembly 4 ensures a full-bore structure during material discharge, meaning that the discharge port 22 is fully open when the baffle assembly 4 is activated, reducing the resistance to material discharge and improving discharge efficiency.
[0026] In addition, to further improve material discharge efficiency, please refer to the appendix. Figure 1 As shown, there are two discharge ports 22, and correspondingly, there are also two discharge ports 451.

The top of the lead screw 61 is connected to the servo motor 63, and the movable seat 65 is fitted on both the lead screw 61 and the guide rod 62 so that the servo motor 63 drives the lead screw 61 to rotate, causing the movable seat 65 to move up and down along the direction of the guide rod 62. In addition, the guide rod 62 is also provided with a limiter 64 to limit the vertical position of the movable seat 65. The stirring rod 7 is circumferentially arranged on the movable seat 65.
[0029] In the above scheme, to reduce the accumulation of material inside the mixing tank 2 after discharge, please refer to the appendix. Figure 1 As shown, the mixing tank 2 has a boss 23 and a feeding platform 24 at the bottom of its interior, so that the bottom of the mixing tank 2 forms two conical spaces to facilitate material discharge. The two discharge ports 22 are respectively located in the two conical spaces.
[0030] To further improve the mixing effect in the above scheme, please refer to the appendix.

Figure 4 As shown, a rubber scraper 9 is provided on the outside of the U-shaped frame 8, and the scraper 9 is in contact with the inner wall of the mixing tank 2.
