Description

Technical Field

[0001] This utility model belongs to the field of filling technology for empty roadways, specifically relating to a high-water-content material filling system for mining ton bags. Background Technology

[0002] In the mining process, backfilling is usually required to ensure the safety and stability of the mine. High-water or ultra-high-water materials have significant advantages such as low material consumption and fast consolidation speed, making them the main materials used in projects such as backfilling along goaf roadways, backfilling of underground empty roadways (abandoned roadways), and fire prevention and extinguishing. High-water or ultra-high-water materials are composed of two components, A and B. The commonly used backfilling equipment mainly consists of four mixing tanks and one double-liquid transfer pump. The four mixing tanks are used alternately in pairs. The material is usually packaged in small bags and needs to be manually poured into the mixing tanks and stirred into a slurry before being pumped out by the double-liquid transfer pump. Traditional backfilling systems have slow slurry preparation efficiency, high labor intensity for workers, and the quality of the slurry cannot be guaranteed, affecting the project results.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0023] like Figure 1 As shown, a high-water-content material filling system for mining ton bags includes a discharge device, a feeding device, a slurry preparation mechanism, and a grouting device arranged sequentially along the roadway. The slurry preparation mechanism includes a first slurry preparation machine 7, a second slurry preparation machine 8, a conveying pump 17, and a main body 6. The first slurry preparation machine 7 and the second slurry preparation machine 8 can be screw slurry preparation equipment, which can discharge slurry to the outlet during the slurry preparation process. The main body 6 is a box-type structure or a frame structure, and the first slurry preparation machine 7 and the second slurry preparation machine 8 are integrated inside the main body 6. The first slurry preparation machine 7 and the second slurry preparation machine 8 are distributed at intervals in the longitudinal direction. The outlet of the first slurry preparation machine 7 is located directly above the inlet of the second slurry preparation machine 8. The proportioned material is sequentially conveyed to the first slurry preparation machine 7 through the feeding device to form high-water-content material. The high-water-content material can be directly grouted to the filling position or conveyed to the second slurry preparation machine 8 for secondary slurry preparation to form ultra-high-water-content material.

[0024] The discharge end of the second pulping machine 8 is connected to the inlet of the conveying pump 17. The discharge end of the conveying pump 17 extends to the low-speed mixer 14. The low-speed mixer 14 continuously stirs the high-water material to prevent the material inside the slurry from settling. The inlet of the grouting device is connected to the low-speed mixer 14. The discharge end of the grouting device extends to the area to be filled through the grouting pipe. The grouting device is the grouting pump 13.

[0025] Among them, the first pulping machine 7, the second pulping machine 8, the conveying pump 17, the low-speed mixer 14 and the grouting pump 13 are all commercially available products, and their structures are not subject to much restriction.

[0026] A buffer tank 10 is provided between the outlet of the first pulping machine 7 and the inlet of the second pulping machine 8. The buffer tank 10 can buffer the high-water material configured in the first pulping machine 7, so that the grouting pump 13 can directly extract the high-water material in the buffer tank 10 for grouting. The buffer tank 10 is connected to the feed end of the grouting device through a connecting pipe. Direct grouting or secondary pulping can be selected according to actual needs. A first electromagnetic control valve 11 is provided between the buffer tank 10 and the grouting device, and a second electromagnetic control valve 12 is provided between the low-speed mixer 14 and the grouting device. The composition of the grout is selected by the first electromagnetic control valve 11 and the second electromagnetic control valve 12, so as to meet different tunnel filling needs.

[0027] In one optional embodiment, the unloading device includes a lifting rail 1 and a pneumatic hoist 3. The lifting rail 1 is fixed to the roof of the tunnel and extends along the roof of the tunnel to the space between the ton bag unloading station and the loading device to transport the ton bag 2 to the loading device.

[0028] The feeding device includes a ton bag unloading platform 4 and a spiral feeding pipe 5. The ton bag unloading platform 4 and the spiral feeding pipe 5 are commercially available products. The feeding end of the spiral feeding pipe 5 extends to the discharge port of the ton bag unloading platform 4, and the discharge end of the spiral feeding pipe 5 extends to the inlet of the first pulping machine 7. In this embodiment, the driving device of the spiral feeding pipe 5 is a speed-regulating motor, so that the feeding speed can be adjusted according to actual needs.

[0029] Furthermore, a weight sensor is installed below the ton bag platform to detect the weight of the material being fed. Based on this weight, the water feeding speed can be selected to ensure accurate slurry mixing ratio.

[0030] Specifically, the first pulper 7 and the second pulper 8 are respectively equipped with water supply mechanisms 9. The water supply mechanism 9 includes a flow meter and a flow regulating valve. The two water supply mechanisms 9 adjust the water source formula according to the mixing ratio requirements. For example, the water source supplied by the water supply mechanism 9 corresponding to ultra-high water content material can be supplemented with corresponding additives.

[0031] The weight sensor, spiral feed pipe 5, first pulper 7, second pulper 8, flow meter and flow regulating valve are all connected to the controller for automatic proportioning.

[0032] In an optional embodiment, a discharge pipe extending to the inlet of the second pulper 8 is provided below the buffer tank 10. A flow meter and a third electromagnetic control valve 15 are provided on the discharge pipe. The flow meter and the third electromagnetic control valve 15 are connected to a controller, which can control the water supply according to the discharge speed of the second pulper 8 in the high-water material tank to ensure the accuracy of the mixing ratio.

[0033] The outlet of the second pulper 8 is located at the end. The discharge chamber 16 and the inner cavity of the second pulper 8 are interconnected. The discharge chamber 16 and the inner cavity of the second pulper 8 are separated by a partition. The upper part of the partition has a notch. After the pulp mixed in the second pulper 8 reaches a certain height, it overflows into the discharge chamber 16. The feed end of the conveying pump 17 extends into the discharge chamber 16.

[0034] A filter screen is provided at the notch to prevent debris from entering the discharge chamber 16.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
