Embodiment
Below in conjunction with Fig. 2, the present invention will be further described:
But a kind of automatic pollution discharge and the underflow pump that automatically cleans, comprise underflow pump 2, at underflow pump 2 two ends underflow pump inlet tube 3 and underflow pump outer pipe 4 are set respectively, offer first drain pipe 11 to downward-extension at underflow pump outer pipe 4, be provided with the 3rd check valve 7 at this first drain pipe 11, the described underflow pump outer pipe 4 between underflow pump 2 and drain pipe is provided with the second check valve 6 simultaneously.When underflow pump breaks down, above-mentioned the first drain pipe 11 and the 3rd check valve 7 can be so that the backflow ore pulp be no longer flowed through underflow pump 2, but directly in time discharge by the first drain pipe 11.
On the underflow pump outer pipe 4 between underflow pump 2 and the second check valve 6, also be connected water producing pipe 10 in all one's life, be provided with the 4th check valve 8 producing water pipe 10; Connect the second drain pipe 1, the second drain pipe 1 to downward-extension at underflow pump inlet tube 3 simultaneously and be provided with the first check valve 5.When underflow pump breaks down, be certain to more remaining ore pulps in underflow pump 2 and the underflow pump inlet tube 3, thereby by external production water, directly wash away underflow pump 2 and underflow pump inlet tube 3, and the sewage after will washing away is in time discharged by the second drain pipe 1.
Between production water pipe 10 and underflow pump outer pipe 4, also be provided with pressure-equalizing pipe 12, being provided with the 5th check valve 9, the second check valves 6 and the 4th check valve 8 at pressure-equalizing pipe 12 is positioned at and produces water pipe 10, underflow pump outer pipe 4 and pressure-equalizing pipe 12 and form on the returns.The main cause that this pressure-equalizing pipe 12 is set be because: the common pressure of transfer ore pulp all can be greater than producing the pressure of producing water in the water pipe 10 in the underflow pump 2, if there are not 12 pairs of ducted ore pulps of pressure-equalizing pipe to reduce pressure, produce water and can't clean underflow pump 2 and underflow pump inlet tube 3.
But the working principle of above-mentioned automatic pollution discharge and the automatic underflow pump that cleans is as follows:
When underflow pump 2 broke down, high-concentration ore slurry utilization deadweight fell after rise fast, and at this moment the second check valve 6 on the underflow pump outer pipe 4 is closed, and stoped moving on of ore pulp backflow, had protected underflow pump equipment; Simultaneously the 3rd check valve 7, the 5th check valve 9, the first check valve 5 and the 4th check valve 8 are opened, sewage is discharged underflow pump 2 from the second drain pipe 1 after producing the long-pending ore deposit cleaning in the water flushing underflow pump 2, and also discharge from the first drain pipe 11 in the long-pending ore deposit in the underflow pump outer pipe 4 simultaneously; After underflow pump was handled well, the minimizing and the pressure that reflux along with ore pulp constantly descended, and the 5th check valve 9 will be closed first, after treating that underflow pump 2 is restarted, the first check valve 5, the 3rd check valve 7 and the 4th check valve 8 will be closed, and at this moment the second check valve 6 is opened, and underflow pump 1 begins normal operation.
If underflow pump 2 damages can't restart, then only need close underflow pump import total valve, ore pulp to be refluxed is drained can to begin maintenance.This device can shorten time and the workload of maintenance.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obvious realization of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technological scheme to carry out; or without improving design of the present invention and technological scheme are directly applied to other occasion, all in protection scope of the present invention.
