Embodiment 1

[0030] Embodiment 1, a kind of coal mine central water tank of online continuous dredging, such as figure 1 As shown, it includes an inclined water tank connected to the central water pump house 10 and the underground parking lot lane 7, and is connected with the inclined water tank to be provided with a coal slurry cooling roadway 4, and is arranged between the coal mud slurry cold transport roadway 4 and the inclined water tank Coal slurry discharge device, desilting device is installed in the inclined water tank and the connecting lane on the top of the tank. The gushing water in the alley 7 of the parking lot at the bottom of the shaft converges from various places and flows to the inclined water tank. The coal slime particles in the gushing water are deposited and accumulated through the inclined water tank, and then the relatively clean water flows to the central water pump house 10, and the central water pump house 10 will be relatively clean. of gushing water discharge...

Embodiment 2

[0041] Embodiment 2, a kind of online continuous desilting coal mine central water tank, such as Figure 4 As shown, the desilting device includes mud pushing jacks 9-4 arranged in pairs in the warehouse roof connecting lane 5, the telescoping ends of the mud pushing jacks 9-4 are connected with a head end steel wire rope, and the head end steel wire rope passes through the head end fixed pulley Connected with the mud pushing device 9 arranged on the bottom surface of the inclined water tank, two groups of mud pushing devices 9 are arranged in parallel, and the two groups of mud pushing devices reciprocate up and down alternately in a cycle.

[0042] Such as Figure 5 , Figure 6 and Figure 9 , Figure 10 As shown, the mud pushing device 9 includes a skeleton pipe 9-1A arranged along the length direction of the inclined water tank, and the two ends of the skeleton pipe 9-1A are all provided with semicircular pull rings 9-6, and the two sides of the skeleton pipe 9-1A Pin ...

Embodiment 3

[0045] Embodiment 3, a kind of coal mine central water tank of online continuous dredging, such as Figure 8 As shown, the diameter of the groove bottom of the end guide pulley 9-5 wheel groove is equal to the distance between the two skeleton pipes 9-1A minus the diameter of the tail-end wire rope, so that the mud pushing device 9 is guaranteed to move along the inclined bottom surface of the inclined water tank. There is no lateral movement when swiping vertically.

[0046] Other structures of this embodiment are the same as those of Embodiment 2.

Abstract

The invention discloses a coal mine central water sump for online continuous desilting. The coal mine central water sump comprises at leas two sections of inclined water sumps with one higher ends andone lower ends of the bottom surfaces; the lower ends of the inclined water sumps communicate with the lower ends of the adjacent inclined water sumps; the higher ends of the two sections of inclinedwater sumps at the two ends of the central water sump are connected with central water pump rooms and shaft station main roadways; coal slurry cool conveying roadways connected with the shaft stationmain roadways are arranged along the lower ends of all the sections of inclined water sumps; mud accumulating pits are formed in the connected lower ends of the inclined water sumps; coal slurry discharge devices are arranged between the mud accumulating pits and the coal slurry cool conveying roadways; sump top communicating roadways are arranged between the tops of the lower ends of the inclined water sumps and the tops of the coal slurry cool conveying roadways for communication; and desilting devices continuously operated online are arranged in the inclined water sumps and the sump top communicating roadways. The coal mine central water sump realizes high-lower and high-efficiency continuous desilting in a non-stop state and high-concentration or even solid-state transportation of coal slurry, reduces the desilting cost, and improves the operation safety.

Description

technical field [0001] The invention relates to the technical field of coal mine production and safety, in particular to a coal mine central water tank for online continuous dredging. Background technique [0002] The central water tank under the coal mine is an indispensable part of the mine drainage system, and it is a roadway lower than each mining level of the mine. Water gushes from all parts of the mine into the central water tank, and slowly flows through the water tank to the water pump room. During the slow flow, the solid particles such as coal powder and rock powder carried by the water gushing water are clarified and separated from the water, and the clean water passes through the water pump at the outlet of the water tank. It is discharged to the ground, and the solid particles settle at the bottom of the water tank along the process to form coal slurry, which is finally cleaned and transported to the ground. [0003] The central water tank must have a certain ...
