Description

Underground water treatment device

Technical Field

The utility model relates to a colliery field, concretely relates to underground water treatment facilities.

Background

A large amount of underground water is generated in underground coal mine exploitation, the underground water also contains a large amount of coal slime, the water needs to be collected by a water sump when the water sump is used for processing the water, the water sump needs to frequently clean silt, the investment labor is large, the safety risk coefficient is high, the abrasion of a water pump and a pipeline is large, the water resource waste is large, and a coagulation reaction is adopted for solving the problems. The inclined tube sedimentation tank carries out sedimentation treatment to eliminate impurities in water, but the treated water has more fine sand, which affects the recycling effect.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, the utility model provides a downhole water treatment device.

The utility model discloses a realize through following technical scheme:

the utility model provides a downhole water treatment facilities, the package communicates each other including coagulating reaction chamber and pipe chute sedimentation tank, and the lower part of this coagulating reaction chamber is provided with the import pipe, pipe chute sedimentation tank upper portion is fixed through the antithetical couplet intercommunication that pipeline and sand filter lower part side set up, the antithetical couplet is fixed with a plurality of branch pipe intercommunication that sets up inside the sand filter, every the spiro union of branch pipe upper portion has a plurality of sand filter pipes that are in the sand filter, it has a plurality of filtration pores to open on the sand filter pipe outer wall, the cotton filter sleeve pipe that covers the filtration pore has been cup jointed to the outside of sand filter pipe.

Preferably, the upper part of one side of the sand screen is connected with a conveying pipe.

Compared with the prior art, the beneficial effects of the utility model are that: this practicality is through the precipitation filtration effect in thoughtlessly congeal reacting chamber, pipe chute sedimentation tank and sand filtering pond, thoroughly solves the sump desilting difficult problem in the pit, reduces the safe risk of sump desilting operation in the pit, realizes filtering and reaches the retrieval and utilization of going up to the well of emission water quality standard liquid, greatly reduced elevator pump and pipe-line system's operating load, reduce the drainage system wearing and tearing, reduce and maintain, maintenance cost, power saving and energy saving realizes water resource reutilization, energy-concerving and environment-protective.

FIG. 1 is a schematic view of the connection of the present invention;

FIG. 2 is a schematic structural view of a sand filter according to the present invention;

FIG. 3 is another schematic structural view of the sand filter of the present invention;

FIG. 4 is a schematic structural view of internal parts of the sand filter of the present invention;

in the figure: the device comprises a coagulation reaction chamber 1, an inclined tube sedimentation tank 2, an inlet pipe 3, a sand filter tank 4, a connecting pipe 5, a branch pipe 6, a sand filter pipe 7, a filter hole 71, a filter cotton sleeve 8 and a conveying pipe 9.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, 2, 3 and 4, a downhole water treatment device comprises a coagulation reaction chamber 1 and an inclined tube sedimentation tank 2 which are mutually communicated, wherein an inlet pipe 3 is arranged at the lower part of the coagulation reaction chamber 1, the upper part of the inclined tube sedimentation tank 2 is communicated and fixed with a connecting pipe 5 arranged at the lower side end of a sand filter tank 4 through a pipeline, the connecting pipe 5 is communicated and fixed with a plurality of branch pipes 6 arranged inside the sand filter tank 4, a plurality of sand filtering pipes 7 positioned in the sand filter tank 4 are screwed at the upper part of each branch pipe 6, a plurality of filtering holes 71 are formed in the outer wall of each sand filtering pipe 7, and a cotton filtering sleeve 8 covering the filtering holes 71 is sleeved outside the sand filtering pipes 7.

The upper part of one side of the sand filtering pipe 7 is connected with a conveying pipe 9.

The working principle is as follows: the mine water is lifted to a primary sedimentation regulating tank through an underground drainage pump, and is lifted to a coagulation reaction chamber 1 and an inclined tube sedimentation tank 2 of an integrated water treatment facility after primary sedimentation, and a coagulant is added into the coagulation reaction chamber 1 to be fully mixed with the treated water and completely reacted so as to accelerate sedimentation and improve clarification effect; the 1 play water of coagulation reaction chamber deposits the back through pipe chute sedimentation tank 2, the coal slime that the pipe chute sedimentation tank 2 bottom was gathered is transported to the coal yard through the hydroextractor dehydration and is handled, the supernatant at pipe chute sedimentation tank 2 top gets into the UNICOM 5 through the pipeline, and get into in each minute pipe 6 in the sand filter 4 through UNICOM 5, discharge through the filtration pore 71 on the sand screen 7 on minute pipe 6 upper portion, it filters to be filtered by the cotton filter 8 that cup joints on the sand screen 7, the water that gets into the sand filter 4 like this is cleaner, it reaches the requirement of emission water quality standard and discharges through conveyer pipe 9 and retrieval and utilization, when the cotton filter 8 of each sand screen 7 on the minute pipe 6 gathers impurity more, can twist out the sand screen 7 from minute pipe 6 and change cotton filter 8, it is comparatively convenient to maintain.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
