Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

Examples

Referring to fig. 1, in order to provide a coal mine sump dredging system according to an embodiment of the present invention, as shown in fig. 1, the system includes a pump room, a water pump 1 is disposed in the pump room, and a water inlet pipe of the water pump 1 is connected to a filtering mechanism 2 having a non-return function; the filtering mechanism 2 is used for separating a solid-liquid mixture in the water sump, discharging solid substances through the lower part of the filtering mechanism 2 and making liquid substances enter the water pump 1 through the upper part of the filtering mechanism;

the mud pump 3 is connected with the lower part of the filtering mechanism 2 through a pipeline; the mud pump 3 is used for pumping the solid substances discharged by the filtering mechanism 2 out to a mud pit 4.

The filtering mechanism comprises a cylinder body and a cone which are connected, wherein the top of the cylinder body is connected with the water inlet pipe, a liquid inlet is formed in the side surface of the cylinder body, and a discharge outlet is formed at the bottom of the cone; a partition board is fully distributed in a flat layer in the cylinder, a through hole penetrating through the upper surface and the lower surface of the partition board is formed in the partition board, a vertical pipe is formed below the partition board at a position opposite to the through hole, and a hinged valve plate capable of being opened upwards is formed above the partition board at a position opposite to the through hole; the solid-liquid mixture enters the cylinder body through the liquid inlet along the tangential direction of the cylinder body. This system is when using, need draw water and can start the water pump, under the suction effect of water pump, the valve plate can upwards lift up and open the through-hole on the baffle, solid-liquid mixture can get into the drum through the inlet this moment internal, owing to enter into along the tangential of drum, can take place rotatoryly in the drum, the great solid matter of density can move down and get into in the cone finally by the bin outlet of cone lower part discharge, the less liquid of density can be discharged by the pit after getting into the pressurization of water pump in the water pump through the riser. Solid substances discharged from the discharge port are pumped into the slurry pool under the action of the slurry pump, so that the aim of draining water and cleaning sludge deposited at the bottom of the sump is fulfilled.

In order to detect the sludge amount in the water sump, a material level meter 5 is arranged in the water sump, and the material level meter 5 is used for detecting the position of sediment in the water sump relative to the bottom of the water sump. In order to prevent the working personnel from being warned when the sludge cleaning amount is less than the deposition amount, the sludge cleaning device further comprises a controller 6, and the controller 6 is connected with the level gauge 5 and a warning assembly 7. In order to solve the problem that when the water pump is stopped, the sludge deposition amount of the water sump is too large and the water sump is not easy to enter a filtering mechanism, the water outlet end of the water pump is connected with a water outlet pipe 8 and a back flushing pipe 9, and the back flushing pipe 9 extends to the bottom of the water sump; the drain pipe 8 and the back flushing pipe 9 are both provided with an electromagnetic valve 10, and the electromagnetic valve 10 is connected with the controller 6. Furthermore, a part of the backflushing pipe, which is positioned inside the water sump, is of a plum blossom-shaped tubular structure. After the water pump is stopped and is opened again, the drain pipe electromagnetic valve can be controlled to be closed, the back flushing pipe electromagnetic valve is controlled to be opened, at the moment, the water pump can circulate water in the water sump, deposited sludge in the water sump is back flushed through the back flushing pipe to enable the deposited sludge to form a flowing state, and the deposited sludge can smoothly enter the filtering mechanism to be filtered and separated. The plum blossom pipe can ensure better recoil effect. Since the mud pump transfers a part of water into the mud pit during pumping, in order to discharge the water in the mud pit in time and transfer the water out of the well, the embodiment of the present invention may provide that the mud pit is located above the sump, and the mud pit 4 is formed with a liquid discharge port 11 connected to the sump.

In a word, the coal mine sump dredging system that this application provided, simple structure is reasonable, and installation convenient to use can realize the synchronous silt in the clearance sump of drainage in-process, prevents that silt deposit is too much in the sump, influences the water storage capacity in sump. The system has the advantages of compact structure of the adopted equipment, low energy consumption and large-area popularization and use value.
