Referring to fig. 1 to 3, the system for backwashing a filter of a water supply pipeline in a coal mine comprises a water tank, a water suction pump, a front three-way valve, a filter, a rear three-way valve, a slurry pump and a water discharge valve. The water outlet of the water tank is connected with a water suction pump, the water outlet of the water suction pump is connected with a first port (a port close to the left in the drawing) of the front three-way ball valve, and a second end (a port close to the right in the drawing) of the front three-way ball valve is connected with the filter; the port A (port close to the left in the figure) of the back three-way ball valve is connected with the filter, and the port B (port close to the left in the figure) is connected with the water inlet of the mud pump; a communication pipeline for connecting the front three-way ball valve and the rear three-way ball valve is arranged between the front three-way ball valve and the rear three-way ball valve, namely, a third port (a port close to the upper part in the figure) of the front three-way ball valve is connected with a port C (a port close to the upper part in the figure) of the rear three-way ball valve; the two-way ball valve is arranged between the front three-way valve and the filter, one end of the two-way ball valve is communicated with the outside, and the other end of the two-way ball valve is connected with a pipeline for connecting the control valve and the filter.
The specific working principle is as follows:
the system has three working modes, namely a normal water supply mode, a reverse flushing mode and a temporary water supply mode, and the three working modes correspond to the states that the front three-way ball valve, the rear three-way ball valve and the two-way ball valve are in different valve positions.
In the normal water supply mode: a first port and a second port of the front three-way ball valve are opened, and a third port is closed; the port A and the port B of the rear three-way ball valve are opened, the port C is closed, the front three-way ball valve and the rear three-way ball valve communicate the water outlet of the water suction pump, the filter and the water inlet of the slurry pump, and when the two-way ball valve is in a closed state, water in the water tank is normally supplied to the slurry pump. Water supply direction: the water tank → the water suction pump → the front three-way valve → the filter → the rear three-way valve → the slurry pump, namely, the water flow flows to the slurry pump according to the original water supply pipeline.
In a back flush mode: the valves of the front three-way ball valve and the rear three-way ball valve rotate, the first port and the third port of the front three-way ball valve are opened, and the second port is closed; the A port and the C port of the back three-way ball valve are opened, the B port is closed, and when the two-way ball valve is in an opening (communicating) state, the backwashing water supply direction is as follows: water tank → water suction pump → front three-way valve → communication pipe → back three-way valve → filter → two-way ball valve. This system can make the water in the water tank from the filter delivery port end back flush filter inlet end's deposit impurity, and make impurity pass through two-way ball valve discharge water supply pipe, need not cut off water and dismantle water supply pipe, can directly utilize the water in the water tank to accomplish the work of washing of filter, the work load of wasing the filter has been reduced, a large amount of time has been saved, even if the user forgets timely clearance, also need not occupy too much engineering time and go to accomplish the cleaning work, the efficiency of construction has been improved.
In the temporary water supply mode: the valves of the front three-way ball valve and the rear three-way ball valve rotate, the first port and the third port of the front three-way ball valve are opened, and the second port is closed; the C port and the B port of back tee bend ball valve are opened, and the A port is closed, and when preceding tee bend ball valve and back tee bend ball valve directly communicate suction pump delivery port and slush pump water inlet, change the interim water supply direction of filter: water tank → suction pump → front three-way valve → communication pipeline → rear three-way valve → slurry pump. The system can bypass the filter and directly supply water to the slurry pump through the communicating pipe, and the filter can be replaced conveniently when damaged suddenly.
This scheme can guarantee under the normal condition, for the normal water supply of slush pump, does not receive other pipeline structure influences. When the mud pump is used for a long time, the deposited impurities at the filter can be caused to excessively influence the water supply of the mud pump, the valve positions of the front three-way valve and the rear three-way valve can be directly changed, so that the flow direction of water in the water supply pipeline is changed, the water inlet of the filter is reversely flushed from the water outlet direction of the filter, the deposited impurities at the water inlet of the filter can be easily flushed away, the water with the impurities can flow out of the water supply pipeline from the positions of the two ball-shaped pipes, and the adverse effect on the water supply pipeline can not be caused. Meanwhile, the structure of the scheme can also support the water suction pump to directly supply water to the mud pump by crossing the filter; when the filter is damaged suddenly and cannot be used, the filter is usually required to be detached for replacement, and water cannot be continuously supplied to the slurry pump during the period, so that the construction efficiency is influenced; and this scheme of adoption, when this kind of condition appears, can be temporarily through the pipeline between preceding three-way valve and the back three-way valve directly provide the slush pump with water to can accomplish the change work of filter on the basis of not stopping the construction, improved the stability of system in the face of emergency.
Although the reverse flushing mode and the temporary water supply mode can enable part of water with impurities to enter the slurry pump, the time is short, the amount of the water with impurities entering the slurry pump is small, and the slurry pump needs to be regularly attended (outside the construction time period), so that the slurry pump cannot be influenced, and the normal operation of construction cannot be influenced.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
