Embodiment 1
[0029] Such as figure 2 , image 3 with Figure 4 As shown, a heavy medium velocity submerged water treatment equipment used in underground coal mines includes a treatment tank 1, which is arranged below the ground. The treatment tank 1 has a partition 2 fixed inside, and the height of the partition 2 is less than that of the treatment tank. Half the depth of the inner cavity of tank 1, the linear distance from partition 2 to the side of pretreatment zone 3 is less than the linear distance from partition 2 to the side of flocculation zone 4. The partition 2 divides the treatment tank 1 into pretreatment zone 3 and flocculation zone 4. A collection bottom plate 5 is placed at the bottom of the pretreatment zone 3. The height of the collection bottom plate 5 is equal to the height of the partition plate 2. The horizontal cross-sectional shape of the collection bottom plate 5 is equal to the horizontal cross-section shape of the pretreatment zone 3, and the top of the collection bo...
Embodiment 2
[0031] The second embodiment is a further improvement on the first embodiment.
[0032] Such as figure 1 , figure 2 , Figure 5 with Image 6 As shown, the top edge of the treatment tank 1 is symmetrically fixed with two sets of support plates 20 at the position of the flocculation zone 4. The horizontal distance between the support plates 20 is equal to the length of the flocculation zone 4, and a first bearing is installed at the center of the side of the support plates 20. 21. A through hole 22 is opened in the center of the side of the supporting plate 20 of the other group, and a servo motor 24 is fixed at the center of the side. A second bearing 23 is installed inside the through hole 22. The output end of the servo motor 24 is connected with a rotating shaft 25, and the end of the rotating shaft 25 A screw 26 is connected through the second bearing 23. The length of the screw 26 is equal to the distance between the supporting plates 20. The other end of the screw 26 is ro...

Abstract
The invention relates to the field of coal mines, and particularly relates to dense-medium quick-sinking water treatment equipment for an underground coal mine. A pretreatment area and a filter plateare arranged, so that preliminary filtration is carried out through a filter plate on the pretreatment area before mine water flocculation and the subsequent flocculation effect is improved; meanwhile, an insertion groove, an insertion plate, a vertical groove, a vertical plate, a fixing plate, a connecting plate, a penetrating screw hole, a connecting screw hole and a connecting screw rod are arranged, so that the insertion fit of the insertion groove, the insertion plate, the vertical groove and the vertical plate is utilized, the filter plate is convenient to mount and dismount, and the connecting screw rod is in threaded connection with the penetrating screw hole and the connecting screw hole for fixing; a collecting bottom plate, a vertical rod, a transverse plate and a through hole are arranged, and therefore, when the pretreatment area needs to be cleaned, a rope penetrates through the through hole and is externally connected to a device to lift out the transverse plate, so thatsolid impurities in the pretreatment area are discharged; a collecting tank, a lifting rod and a lifting lug are arranged, and the rope penetrates through the lifting lug and is externally connectedto a device to lift out the collecting tank, so that other flocculated impurities are cleaned.
Description
Technical field [0001] The invention relates to the field of coal mines, in particular to a heavy medium velocity submerged water treatment equipment used in coal mines. Background technique [0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into shaft coal mines and open-pit coal mines. Most of the coal mines in China belong to shaft coal mines. The scope of coal mines includes large areas above and below ground and related facilities. It means that in the process of coal mining, groundwater is in contact with coal seams and rock formations, coupled with the influence of human activities, a series of physical, chemical and biochemical reactions have occurred, so the water quality has obvious characteristics of the coal industry, and mine water containing suspended solids The content of suspended solids is much higher than that of surface water, with poor sensory properties; and the suspended solids contained in...
