Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a mixing device for phosphogypsum-based gelling filling materials. Background Technology

[0002] Phosphogypsum-based cementitious backfill material is an engineering material formed by mixing and hydration reaction of phosphogypsum as the main raw material, combined with cementing materials and functional additives. Its core objective is to transform phosphogypsum, an industrial solid waste, into an environmentally friendly material applicable to mine backfilling, foundation reinforcement, and other scenarios. The mixing device mixes phosphogypsum, cementing materials, water, and additives in a specific ratio to form a homogeneous slurry that meets the requirements of backfilling projects for fluidity, strength, and stability.

[0003] The mixing device stirs the material by stirring blades. However, there are some dead corners that cannot be effectively stirred when stirring blades are stirring, such as the bottom of the mixing tank. In order to prevent wear, the stirring blades leave a certain gap between themselves and the inner wall of the mixing tank. This results in the material at the bottom not being effectively stirred, and there will be a certain stirring blind zone. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a mixing device for phosphogypsum-based gel filling materials that allows the material at the bottom of the mixing tank to circulate, thereby improving the uniformity of mixing, preventing the existence of dead zones in the mixing, and avoiding the occurrence of material stratification.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, the phosphogypsum-based gelling filling material mixing device proposed in this utility model includes a mixing tank 1 and a mixing mechanism installed inside the mixing tank. The mixing mechanism includes two rotating shafts 2 rotatably installed inside the mixing tank 1. Multiple stirring blades 201 are fixedly installed on the rotating shafts 2, and a first gear 202 is fixedly installed on the rotating shafts 2. The two first gears 202 mesh with each other. A reducer 203 is fixedly installed on one side of the mixing tank 1. One of the rotating shafts 2 is coaxially and fixedly connected to the output shaft of the reducer 203. A first pulley 204 is fixedly installed at the input end of the reducer 203. The first pulley 204 is connected to a power source through transmission, which can drive the reducer 203 to rotate. The reducer drives the first gear 202 to rotate, so that the two rotating shafts 2 rotate synchronously in opposite directions. The stirring blades 201 stir the material, thus mixing the material.

[0025] like Figure 1 , Figure 2 As shown, in this embodiment, the mixing device includes a feeding trough 3 located at the bottom of the mixing tank 1. A sealing assembly for sealing the feeding trough 3 is installed on the feeding trough 3. The sealing assembly includes a sealing plate 301 rotatably installed at the bottom of the mixing tank 1. A first motor 302 is fixedly installed on the mixing tank 1. The output shaft of the first motor 302 is fixedly connected to the sealing plate 301. The first motor 302 can drive the sealing plate 301 to rotate. Rotating the sealing plate 301 allows it to adhere to or leave the feeding trough 3, thereby sealing or releasing the feeding trough 3. The material inside the mixing tank 1 can leave the bottom of the mixing tank 1 through the feeding trough 3.

[0026] like Figures 3 to 5As shown, in this embodiment, the mixing device also includes a return module. The return module is installed on the mixing tank 1 and located on one side of the discharge trough 3. The return mechanism receives the material passing through the discharge trough 3 and pours the material onto the top of the mixing tank 1. The return module includes support plates 4 rotatably installed on both sides of the mixing tank 1. A material box 401 is rotatably installed between the two support plates 4. A drive assembly is installed on the mixing tank 1 to drive the support plates 4 to rotate. The material passing through the discharge trough 3 will enter the material box 401. Then, the drive assembly drives the support plates 4 to rotate, thereby moving the material box 401 to the top of the material box 401. During the upward movement of the material box 401, since the material box 401 can rotate freely, the material box 401 can remain vertical under the action of gravity, preventing the material box 401 from overturning during the upward movement and avoiding premature leakage of material.

[0027] Furthermore, the drive assembly includes a second gear 402 fixedly mounted on one of the support plates 4, and a third gear 403 rotatably mounted on the mixing tank 1. The second gear 402 and the third gear 403 mesh with each other. A second pulley 404 is fixedly mounted on the third gear 403. The second pulley is connected to the power source through a transmission belt. The power source drives the third gear 403 to rotate, thereby driving the second gear 402 to rotate. The rotating second gear 402 can drive the support plate 4 connected to it to rotate.

[0028] Furthermore, a flipping assembly is installed on one of the support plates 4. The flipping assembly drives the material box 401 to rotate. The flipping assembly includes a push rod motor 407 fixedly installed on the support plate 4. A mounting base 408 is fixedly installed on the output shaft of the push rod motor 407. A second motor 409 is fixedly installed on the mounting base 408. The output shaft of the second motor 409 is connected to the material box 401 through a connector. The push rod motor 407 can drive the second motor 409 to move closer to or away from the material box 401, which can control the connection status of the connector. When the connector is connected, the second motor 409 can drive the material box 401 to rotate. The rotating material box 401 can then be flipped, causing the material inside the material box 401 to pour out.

[0029] The connector includes a connecting plate 405 fixedly installed on the material box 401. The connecting plate 405 has a toothed groove 406. A locking block 410 that engages with the groove 406 is fixedly installed on the output shaft of the second motor 409. The locking block 410 can be driven into or out of the groove 406 by the push rod motor 407. When the locking block 410 enters the groove 406, the material box 401 can be flipped by the second motor 409.

[0030] In this embodiment, the first motor 302 can drive the sealing plate 301 to rotate. Rotating the sealing plate 301 can make it fit onto the feeding trough 3 or leave the feeding trough 3, thereby sealing or releasing the feeding trough 3.

[0031] When the material bin 401 is below the material chute 3, the material chute 3 is opened, and the material through the material chute 3 will enter the material bin 401. Then, the material chute 3 is blocked by the sealing plate 301. Then, the support plate 4 is rotated by the drive component, which can move the material bin 401 to the top of the material bin 401. Then, the material bin 401 is flipped by the second motor 409, so that the material is poured onto the top of the mixing tank 1, thereby making the material circulate back and forth and eliminating the dead corners of the mixing.

[0032] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
