Accordingly, further developments and improvements are still needed in the art.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, an automatic low-concentration slurry suction device for a pre-settling tank is proposed, which uses the density difference between high-concentration slurry and low-concentration slurry to suck low-concentration slurry with lower density and reduce the water treatment pressure of a secondary water purification station.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a low concentration coal slime water automatic suction means for preliminary sedimentation equalizing basin, its includes and carries out the pipe that absorbs water of flexible coupling with preliminary sedimentation equalizing basin elevator pump, and sets up and be used for adjusting the buoyant device that the water sucking mouth position was in low concentration coal slime aquatic all the time at the pipe water sucking mouth that absorbs water end.
Preferably, the suction pipe comprises an elbow pipe in flexible connection with the lift pump and a long pipe connected with the elbow pipe and used for sucking low-concentration slime water.
Preferably, the long pipe comprises a conveying port connected with the elbow pipe and a water suction port arranged on the upper side of the slime water.
Preferably, the buoyancy device is arranged at the water suction port end of the long pipe, and the buoyancy device comprises a buoyancy tank and low-concentration coal slime water filled in the buoyancy tank.
Preferably, the top end of the buoyancy device is higher than the top end of the water suction port of the long pipe.
Preferably, the height difference between the top end of the buoyancy device and the top end of the water suction port of the long pipe is not less than 0.5 m.
Has the advantages that:
the utility model provides a sink automatic suction means of low concentration coal slime water for equalizing basin in advance, the device simple structure, simple to operate, and the water sucking port end can float from top to bottom along with the liquid level, when guaranteeing the efficiency that the elevator pump absorbs low concentration coal slime water, avoids absorbing high concentration coal slime water, reduces the water purification pressure of follow-up water purification process, increases water purification efficiency, reduces medicament consumption and staff intensity of offeing medicine, has practiced thrift the cost.
Drawings
Fig. 1 is a schematic structural diagram of a low-concentration slime water automatic suction device for a pre-settling regulating tank in an embodiment of the present invention.
In the drawings: 100 lift pumps, 200 elbows, 300 long pipes, 400 buoyancy devices, 500 pre-settling conditioning tanks.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustration and not for limitation of the present invention.
As shown in fig. 1 the utility model provides a low concentration coal slime water automatic suction means for equalizing basin sinks in advance, it includes and carries out the pipe that absorbs water of flexible coupling with equalizing basin elevator pump 100 in advance, and sets up and be used for adjusting the buoyant device 400 that the mouth position of absorbing water was in low concentration coal slime aquatic all the time absorbing water mouth position at the pipe that absorbs water.
It is specific, the pipe that absorbs water includes return bend 200 with 100 soft couplings of elevator pump, and be connected the long tube 300 that is used for absorbing low concentration coal slime with return bend 200, through at 100 soft couplings return bend 200 of elevator pump and long tube 300, make the coal slime bottom the pond of elevator pump 100 extraction originally, change into the coal slime of elevator pump 100 extraction surface of water below, increased and absorb efficiency, need not can absorb the low concentration coal slime of pre-settling regulating reservoir 500 top with the evacuation of high concentration coal slime below the pre-settling regulating reservoir 500, can effectively reduce high concentration coal slime simultaneously because unable complete evacuation passes through the possibility of elevator pump 100 suction secondary water purification station.
In a preferred embodiment, the elbow pipe 200 is connected with the lift pump 100 through interference fit, so that high-concentration slime water is effectively prevented from being sucked into the secondary water purification station due to the connection gap between the elbow pipe 200 and the lift pump 100.
In a preferred embodiment, the bent pipe 200 is connected with the long pipe 300 through an interference fit, so that the lift pump 100 can be prevented from sucking high-concentration slime water.
Specifically, the long pipe 300 includes a transportation port connected to the elbow pipe 200 and a water suction port disposed at an upper side of the slime water.
Specifically, the buoyant device 400 is arranged at the water suction port end of the long pipe 300, the buoyant device 400 comprises a buoyant tank and low-concentration coal slime water filled in the buoyant tank, and the density in the buoyant tank is kept unchanged, so that the water suction port end of the long pipe 300 can be always kept in a low-concentration coal slime water area in the process that the new mine water liquid level is introduced into the pre-settling regulating reservoir 500 to rise or the liquid level is reduced due to the absorption of water in the pre-settling regulating reservoir 500, and the phenomenon that the water suction port of the long pipe 300 is separated from the liquid level or enters the high-concentration coal slime water due to the change of the liquid level of the pre-settling regulating reservoir 500 is avoided.
Specifically, the top end of the buoyancy device 400 is higher than the height of the top end of the water suction port of the long pipe 300.
Specifically, the difference in height between the top end of the buoyancy device 400 and the top end of the water suction port of the long tube 300 is not less than 0.5m, when a worker finds that the top end of the buoyancy device 400 is exposed out of the water surface, it indicates that the liquid level of low-concentration coal slime water in the pre-settling regulating reservoir 500 is extremely low, most of the coal slime water without high concentration is not in the high-concentration coal slime water, the machine needs to be shut down to enable the pre-settling regulating reservoir 500 to be pre-settled again, and high-concentration coal slime water is prevented from being sucked.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
