Description

Technical Field

[0001] This utility model relates to the field of tailings sand solidification technology, specifically a tailings sand solidification stirring and mixing device. Background Technology

[0002] Tailings sand refers to the waste material generated during the extraction of useful substances such as metallic minerals from mines, through processes such as crushing, grinding, and flotation. Because tailings sand contains a large amount of suspended solids, heavy metals, and other harmful substances, it can cause significant environmental damage if not properly treated, such as soil erosion, land degradation, and water pollution. To reduce the environmental impact of tailings sand, solidification treatment is necessary. The main component of organic solidifying agents is polymer, which can form a high-strength, high-toughness solidified material with the tailings sand. During the solidification process, it is crucial to ensure effective mixing between the tailings sand and the solidifying agent to achieve proper solidification. This requires appropriate mixing equipment.

[0003] The prior art patent application number 202110856223.8 proposes a tailings sand brick-making mixing system, including a shell, a feeding and weighing device on the rear side of the shell for adding appropriate proportions of raw materials and ingredients, a mixing device in the middle of the shell for stirring and mixing the added raw materials and ingredients evenly, and a discharge and cleaning device on the front side of the shell for completely removing the mixed raw materials from the mixing device.

[0004] The above-mentioned equipment has the following shortcomings: after mixing, the material is discharged directly and needs to be temporarily stored using a corresponding material storage device before it can be filled. It cannot be convenient to proceed directly to the next step, and its functionality is low. At the same time, the main mixing mechanism consists of a stirring roller and a stirring blade. The stirring blade is the main mixing mechanism, and the stirring roller connects and assists the stirring blade in moving up and down and rotating. Since the material is relatively viscous during the mixing process, the up and down movement speed of the stirring blade is limited, which leads to a decrease in the overall mixing efficiency.

The inner groove is opened at the top of the fixed plate, and the conveying pipe is fixedly installed at the bottom of the fixed plate and communicates with the inner groove. The mixed slurry can be evenly conveyed into the mold through the conveying pipe via the inner groove.

[0010] The tailings feed pipe is connected to the interior of the main body, and the curing agent feed pipe is connected to the tailings feed pipe.

[0015] As a preferred technical solution of this utility model: the pull-out plate is inserted into the bottom box and the protruding edge corresponds to the slide groove; the material conveying pipe is fixedly installed at the bottom of the fixed plate and communicates with the inner groove; there are several sets of molds and they are fixedly installed on the pull-out plate; the number of molds is the same as that of the material conveying pipe and their positions correspond to each other.

[0016] Compared with the prior art, the present invention provides a tailings sand solidification and mixing device, which has the following beneficial effects:

[0017] 1. This tailings sand solidification and mixing device is equipped with a bottom box pull-out plate, a protruding edge, a mold, a fixed plate, an inner tank, and a conveying pipe. After mixing is completed, the valve can be opened to allow the mixed slurry to enter the bottom box and then the inner tank. It then falls into the mold through the conveying pipe. After the mold gradually fills up, the pull-out plate can be directly pulled out and replaced with a new one to continue collecting the mixed slurry. The slurry gradually solidifies in the mold, thus completing the solidification process. The entire device can directly fill the mixed slurry and wait for it to solidify, thus improving the overall functionality of the equipment.

The motor drives the stirring shaft to rotate, and the stirring rod mixes the material in the main body along with the stirring shaft. During the process, the rotating rod rotates with the stirring shaft, and the contact end of the rotating rod has a large friction with the bottom of the annular groove, so the rotating rod also rotates on its own when it rotates with the stirring shaft. In the process, it also rotates the sleeve assembly and the auxiliary mixing rod. The rotation of the auxiliary mixing rod can turn the material in the main body up and down, while the stirring rod ensures horizontal mixing, which can effectively improve the overall mixing effect.

The output end of the motor 3 extends into the main body 1 and is connected to the top end of the stirring shaft 101. The motor 3 has an electrical connection with an external power source, and can provide sufficient power. There are eight sets of stirring rods 102, which are fixedly connected to the outside of the stirring shaft 101. The fixing ring 103 is sleeved and fixedly installed on the stirring shaft 101. One end of the rotating rod 104 is rotatably connected to the outside of the fixing ring 103.

At the same time, add the curing agent into the main body 1 from curing agent inlet pipe 5 and let it contact the tailings sand. Start motor 3 to drive the stirring shaft 101 to rotate. At the same time, stirring rod 102 mixes the materials in the main body 1 together with stirring shaft 101. During the process, rotating rod 104 rotates with stirring shaft 101. Due to the large friction between the contact end 105 of rotating rod 104 and the bottom of annular groove 108, rotating rod 104 will also rotate on its own when rotating with stirring shaft 101.

After the mixing is completed, the valve 7 can be opened to let the mixed slurry enter the bottom box 8 and the inner tank 1201, and fall into the mold 1103 through the conveying pipe 1202. After the mold 1103 is gradually filled, the pull plate 11 can be directly pulled out and replaced with a new pull plate 11 to continue collecting the mixed slurry. The slurry gradually solidifies in the mold 1103 to complete the solidification. The entire device can directly fill the mixed slurry and wait for it to solidify, which improves the overall functionality of the device.
