Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roadway drainage equipment, in particular to a mine roadway tunneling drainage device. BACKGROUND

[0002] In the construction of shaft and roadway, atmospheric precipitation, surface water, tunnel gushing water, dewatering water, construction water and the like flow into the roadway, forming mine gushing water. In order to ensure the normal construction of shaft and roadway and prevent mine flood, the accumulated water should be discharged in time according to the characteristics of shaft and roadway construction drainage.

[0003] At present, in the process of underground coal mining, due to the large number of water dripping points in the roadway, the tunneling process is greatly affected by accumulated water. In the case of a large amount of accumulated water at the mining face of the roadway, water and coal or coal slurry are formed. If the accumulated water cannot be discharged in time, the tunneling machine is prone to skidding due to the slippery bottom surface of the roadway, thereby limiting the tunneling efficiency of the tunneling machine and seriously affecting the normal tunneling and production quality standard work.

[0004] The traditional drainage technology adopts a single-stage pump and a submersible pump combination extraction method, and manual monitoring of the accumulated water depth is also required. The accumulated water is discharged only after reaching the threshold value, which has a response delay of 30-60 minutes, resulting in continuous deterioration of the accumulated water. For the case of large gushing water, a method of first grouting to block the water source and then layered drainage is required to discharge the water in time. For the case of normal gushing water, the accumulated water is generally collected one by one by the operating personnel and then discharged after unified treatment.

[0005] In the normal gushing water collection operation, the water pump cannot be used for dry pumping, and the operating personnel need to supervise the construction of the drainage equipment, and the water pump needs to be stopped in time when the accumulated water is pumped dry, thereby causing long underground operation time of the operating personnel and low efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0064] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0065] This embodiment relates to a drainage device for mine roadway excavation, as follows: Figures 1 to 3 As shown, the drainage device includes collection components 2 located on both sides of the tunneling machine 1, a filter component 3 located at the rear of the tunneling machine 1's work platform, and a connecting pipe 4 connecting the collection components 2 and the filter component 3. The collection components 2 are fixed to the track frame 101 via connectors 9. The filter component 3 includes a first filter unit 301 and a second filter unit 302, and a collection box 5 located on one side of the first filter unit 301. The inlet of the first filter unit 301 is connected to the connecting pipe 4, and the outlet of the first filter unit 301 is provided with a water outlet pipe 6, which is connected to the inlet of the second filter unit 302.

[0066] Meanwhile, the first filtration unit 301 includes a first housing 3011 with a cavity, and a filter box 3012 pivotally connected to the first housing 3011. Screens 3013 are provided on both sides of the filter box 3012. A first connecting pipe 401 is provided between the connecting pipe 4 and the inner cavity of the filter box 3012. A circulation pipe 3015 is connected to the outlet end of the first connecting pipe 401. A flocculation box 3016 is provided inside the filter box 3012. The circulation pipe 3015 is connected to the inlet of the flocculation box 3016.

[0067] Based on the above design concept, the mine roadway excavation and drainage device of this embodiment, by setting up collection components 2 on both sides of the tunneling machine 1 and placing the collection components 2 on the track frame 101, can collect sewage in the water accumulation ditch on both sides of the roadway while traveling or drilling. The collected sewage is transmitted to the filter component 3 through the connecting pipe 4, and first transported to the first filter unit 301. The sewage enters the filter box 3012 through the first connecting pipe 401, where coal dust and mineral particles in the collected water are trapped. The filtered water enters the cavity of the first box 3011.

[0068] Furthermore, the water flowing through the circulation pipe 3015 enters the flocculation box 3016 and mixes with the flocculant, flowing into the inner cavity of the filter box 3012 and mixing again with the incoming sewage, aggregating the suspended particles in the sewage. Some large particles are filtered out in the filter box 3012, and the filtered water in the cavity enters the second filter unit 302 through the outlet pipe 6 for a second filtration, in order to further reduce impurities and particles in the discharged water and protect the subsequent water treatment equipment.

[0069] Based on the above overall introduction, this embodiment presents an exemplary structure of a mine roadway excavation and drainage device, such as... Figures 1 to 2 As shown, the drainage device can be installed and modified on the existing working platform of the tunneling machine 1 without affecting the existing tunneling machine 1's travel and tunneling work, and is suitable for water treatment in underground mine roadways.

[0070] As a preferred embodiment, such as Figures 4 to 6 As shown, the outer side of the first housing 3011 is provided with a first drive unit 3017 that drives the filter box 3012 to rotate. The cavity is provided with a rotating shaft 3019 arranged along the length direction of the first housing 3011. The power output end of the first drive unit 3017 is pivotally connected to a crank arm 3018, which is sleeved on the rotating shaft 3019. One end of the filter box 3012 is fixed on the rotating shaft 3019. The first drive unit 3017 drives the filter box 3012 to reciprocate to make the inner cavity and the cavity part overlap or separate.

[0071] like Figure 4 and Figure 7As shown, the first driving part 3017 of the embodiment adopts a hydraulic oil cylinder, and the curved arm 3018 is connected to the output shaft of the oil cylinder. When the impurities filtered out of the filter box 3012 need to be removed, the filter box 3012 is driven to rotate by the first driving part 3017, and the coal dust particles and mineral particles are poured into the collection box 5 for unified treatment, so as to avoid the blockage of the filter screen of the filter box 3012. In addition, when the first driving part 3017 drives the filter box 3012 to rotate, the sieve particles adhered to the sieve screen 3013 can be shaken, so as to avoid the blockage of the sieve screen 3013 and effectively ensure the filtering effect and continuous use of the equipment.

[0072] Preferably, as Figures 4 to 8 As shown, the flocculation box 3016 is provided with a spray head 3014 on the side facing the center of the cavity, and the flocculation box 3016 is provided with a containing cavity 30161. The containing cavity 30161 is provided with a box body 30162 for containing flocculating agent, and the box body 30162 is provided with a liquid flow hole 30163 communicating with the containing cavity 30161. The flocculation box 3016 is formed with a water inlet hole 30164 communicating with the circulating pipeline 3015. The spray head 3014 communicates with the containing cavity 30161, and the box body 30162 is arranged below the water inlet hole 30164 and the spray head 3014.

[0073] In the embodiment, two flocculation boxes 3016 are arranged in the filter box 3012. The water filtered for the first time flows through the circulating pipeline 3015 to the containing cavity 30161 of the flocculation box 3016, and the water flows into the containing cavity 30161 through the water inlet hole 30164. Figure 8 As shown, the water inlet hole 30164 is arranged corresponding to the water outlet hole of the spray head 3014 to form the flow of water flow, and then drive the flocculating agent in the box body 30162 to flow outward. When the water flow pressure is insufficient, the push plate 8 arranged in the box body 30162 is pushed by the electric cylinder 7 arranged at the bottom of the containing cavity 30161 to pressurize, so as to drive the flocculating agent to flow out. The diameter of the push plate 8 is equal to the inner diameter of the box body 30162. The amount of flocculating agent can be controlled according to the flow, which will not be described here.

[0074] Therefore, the water in the circulating pipeline 3015 flows out from the spray head 3014 together with the flocculating agent. In some feasible embodiments, a pressure valve can be added to the circulating pipeline 3015 to enable the water flow sprayed by the spray head 3014 to have a certain pressure. The water flow of the spray head 3014 forms an impact with the water flow into the inner cavity of the filter box 3012, so that the flocculating agent and the water are fully mixed to play a coagulation role, improve the uniform contact of the medicament and the water, accelerate the aggregation of the suspended particles, and effectively remove the impurities in the accumulated water.

[0075] As Figures 4 to 6As shown, the filter box 3012 is provided with a second connecting pipe 402, one end of which is communicated with the first connecting pipe 401, and the other end of which is communicated with the circulating pipeline 3015. The second connecting pipe 402 is provided with a plurality of bosses 403 which are spaced along the axial direction of the second connecting pipe 402, and the bosses 403 are formed with water flow holes. The plurality of bosses 403 are spaced along the filter box 3012 to form a plurality of water flow channels, and the multi-channel water flow setting can increase the stirring effect with the flocculating agent and improve the flocculation effect of the solid particles.

[0076] Preferably, the filter box 3012 of the embodiment includes an arc-shaped bending plate 30121, and side plates 30122 connected on both sides of the bending plate 30121.

[0077] Since the filter box 3012 rotates, a hose needs to be arranged at both ends of the second connecting pipe 402 to facilitate the movement requirement of the filter box 3012. As shown in Figure 5 As shown, the circulating pipe is a U-shaped pipe fixed outside the bending plate 30121, one end of the circulating pipeline 3015 is plugged, and the other end is communicated with the second hose.
