Description

Technical Field

[0001] This utility model relates to the field of cemented backfilling technology for mine tailings, specifically to a cemented backfilling device for mine tailings. Background Technology

[0002] To reduce the land use for tailings storage on the surface, solve the environmental pollution caused by tailings stockpiles, and save on the construction, management, and maintenance costs of tailings ponds, my country has widely implemented cemented backfilling of all tailings in underground mines. The main function of cemented backfilling equipment is to use all tailings as backfill aggregate, mixing it with a binder and water to form a cemented backfill slurry. The uniformity of the mixing of tailings and binder is one of the most important indicators for evaluating the cemented backfill slurry. However, the conveying system of current cemented backfilling equipment in mines is prone to blockage, resulting in poor fluidity after the tailings and binder are mixed, making continuous conveying difficult with traditional methods. Furthermore, the lack of temperature control during the conveying process leads to low binder activity at low temperatures, affecting the solidification speed and quality of the backfill. Therefore, we propose a cemented backfilling system for all tailings in mines. Utility Model Content

[0003] The purpose of this utility model is to provide a cemented backfilling equipment for mine tailings, which has the advantages of preventing blockage and having a heated conveying function. It solves the problems of easy blockage in the conveying system of current cemented backfilling equipment for mine tailings, poor fluidity after mixing tailings and cementitious agent, difficulty in ensuring continuous conveying by traditional material conveying methods, lack of temperature control in the conveying process, low activity of cementitious agent in low temperature environment, and affecting the curing speed and quality of backfill.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mine tailings cemented backfilling device, comprising a base plate, an installation platform fixedly connected to the top of the base plate via a bracket, a mixing tank fixedly connected to the top of the installation platform via a bracket, a first motor fixedly connected to the middle of the top of the mixing tank, a stirring rod fixedly connected to the output shaft of the first motor, the stirring rod extending to the lower part of the inner cavity of the mixing tank, a box fixedly connected to the top of the installation platform, a material conveying trough opened in the inner cavity of the box, a material conveying auger rotatably connected to the inner cavity of the material conveying trough via a bearing, a second motor fixedly connected to the right side of the box, the output shaft of the second motor fixedly connected to the material conveying auger, a heating groove opened in the inner cavity of the box and located outside the material conveying trough, an electric heating wire fixedly connected to the inner cavity of the heating groove, and a short pipe opened between the right end of the top of the inner cavity of the material conveying trough and the middle end of the bottom of the inner cavity of the mixing tank.

[0005] Preferably, a stop block is fixedly connected to the left side of the short tube, a third motor is fixedly connected to the top of the box, and a rectangular rubber block is fixedly connected to the output shaft of the third motor.

[0006] Preferably, a discharge port is provided at the left end of the bottom of the inner cavity of the conveying trough, and an insert plate is provided in the inner cavity of the short pipe.

[0007] Preferably, a battery box is fixedly connected to the left end of the top of the base plate, and a storage battery is fixedly connected to the inner cavity of the battery box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a first motor to drive a stirring rod to rotate at high speed in a mixing tank, which fully mixes the tailings and binder, ensuring uniform mixing and improving the stability of the filling body strength. This avoids insufficient strength caused by uneven mixing. A second motor drives a conveying auger to rotate in a conveying trough, stably conveying the mixed materials. The spiral structure of the conveying auger effectively prevents material accumulation and blockage, ensuring the continuity of the filling operation. The heating wire in the heating tank can heat the conveying trough, increasing the temperature of the mixed materials, promoting the activity of the binder, and accelerating the curing speed. It is especially suitable for low-temperature environments, ensuring that the filling body quickly reaches the design strength.

[0012] 2. This utility model uses an insert plate to provide auxiliary control at the short pipe when needed, making it convenient for people to control the opening and closing of the short pipe. Using a third motor, a rectangular rubber block can be driven to rotate. During the rotation of the rectangular rubber block, it will continuously hit the stop block, thereby causing the short pipe to vibrate and preventing the material from sticking to the inner wall of the short pipe and affecting subsequent discharge.
