Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present utility model and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As depicted in figs. 1 and 2, a kind of anti-overflow circulatory system for water immersion type scraping board slag conveyor described in the utility model, comprises dragveyer body 2 and the slag bucket 1 being installed on dragveyer body 2 top.The pipe outlet in conventional refill road 18 is positioned at above the chain of dragveyer body 2 descending branch, conventional refill road 18 is separately installed with check-valves C19, hand-operated valve C20 and motor-driven valve C21.The pipe outlet of chain flushing water pipeline 14 is located at above the chain of dragveyer body 2 section of climbing, chain flushing water pipeline 14 is separately installed with check-valves B15, hand-operated valve B16 and motor-driven valve B17, chain flushing water pipeline 14 chain of water to dragveyer body 2 out rinses.Motor-driven valve B17 is all connected with Control case 22 with motor-driven valve C21, is automatically controlled it by Control case 22.More than be prior art content, also widely use in pulp water self-balancing operational system.
The overflow phenomena that still there will be in pulp water self-balancing operational system, dragveyer body 2 is installed anti-overflow chute 3, and anti-overflow chute 3 is directly installed on dragveyer body 2.Anti-overflow chute 3 is positioned at the upper outside of dragveyer body 2 and around dragveyer body 2, is namely all with anti-overflow chute 3 in the upper outside of dragveyer body 2, preferably anti-overflow chute 3 highly can be designed the upper edge higher than dragveyer body 2.When dragveyer body 2 produces overflow, overflow water does not outflow to enter in anti-overflow chute 3 and temporarily stores, and prevents outflow.In order to ensure that the overflow water in anti-overflow chute 3 is discharged, the entrance of overflow water recovery channel 12 is located at the bottom of anti-overflow chute 3, the bottom of overflow launder 3 can be adopted ramp designs, the entrance of overflow water recovery channel 12 is located at the bottom of slope, is so more better than the discharge of overflow water; The entrance of multiple overflow water recovery channel 12 can also be established in the bottom of anti-overflow chute 3, overflow water can be discharged faster.The pipe outlet of overflow water recovery channel 12 is connected on chain flushing water pipeline 14, overflow water recovery channel 12 is provided with Pulp pump 11.When overflow water needs to discharge, chain flushing water pipeline 14 can be entered under the effect of Pulp pump 11, when chain flushing water uses.Not only solve the emission problem of overflow water, also serve energy-conserving action.Certainly by prior art content, overflow water recovery channel 12 is positioned at Pulp pump 11 two ends and hand-operated valve A9 and check-valves A10 is installed respectively.Overflow water recovery channel 12 is positioned at check-valves A10 other installation motor-driven valve A8, and the control end of motor-driven valve A8 is connected with Control case 22, can be controlled the opening and closing of motor-driven valve A8 by Control case 22.
In order to prevent anti-overflow chute 3 deposit blocking, dragveyer body 2 can install screen pack 5, screen pack 5 be positioned at dragveyer body 2 upper edge and around dragveyer body 2.Screen pack 5 is for the impurity such as cinder, drift pearl in filtrating overflow water, and when dragveyer body 2 finds overflow, overflow water flows into anti-overflow chute 3 through screen pack 5, and contaminant filter wherein gets off by screen pack 5, avoids the discharge of anti-overflow chute 3 to block.Cause operations staff's personal injury and plant environment to pollute in order to high temperature pulp water when preventing from better dropping large slag splashes, splash guard 4 can also be comprised.Arrange intilted splash guard 4 in anti-overflow chute 3 periphery, splash guard 4 is arranged on above anti-overflow chute 3, and towards slag bucket 1, splash guard 4 is tried one's best slag bucket 1 (water seal board) wall.Anti-overflow chute 3 can also be taken over a job therefore overflow pipe 13, the entrance of accident overflow pipe 13 can design attitude as required, below the flood level that usually should ensure to be positioned at anti-overflow chute 3, namely not higher than flood level, but higher than high liquid level, carry out urgent draining for when accident conditions or long-term overtemperature operating mode.
In order to better carry out Automated condtrol, can also comprise two position meter A6 and two position meter B7, two position meter A6 is connected with Control case 22 respectively with two position meter B7, and the control end of Pulp pump 11 is connected with Control case 22.Two position meter A6 is arranged in anti-overflow chute 3, according to actual needs, the high liquid level of two position meter A6 preferably should lower than accident overfall (avoid occurring that water all flows away from accident overfall, water pump does not but also start), low liquid level preferably should guarantee the normal start and stop of Pulp pump 11 and anti-overflow chute 3 as far as possible emptying.Two position meter A6 monitors situation in anti-overflow chute 3, and the pilot signal that two position meter A6 sends is for controlling the opening and closing of motor-driven valve A8 and the start and stop of Pulp pump 11 in the opening and closing of motor-driven valve B17 in chain wash tub pipe road 14 and overflow water reclaim line 12.Two position meter B7 is arranged in dragveyer body 2, same two position meter B7 can set high liquid level as required in flood level, low liquid level at equipment safety operation water level, and the pilot signal that two position meter B7 sends is for controlling the opening and closing of motor-driven valve C21 in conventional refill road 18.
During actual use, when overflow occurs submerged slag conveyor 2, overflow water enters anti-overflow chute 3 temporary reservoir by screen pack 5, there will not be pulp water to arrange phenomenon outward.When the two position meter B7 arranged in dragveyer 2 monitors flood level, control motor-driven valve C21 in conventional refill road 18 by Control case 22 and close.Rely on wet slag band to leak water and evaporation loss, the water level of dragveyer body 2 will drop to ordinary water level gradually, and now two position meter B7 controls motor-driven valve C21 by Control case 22 and opens, and recovers conventional moisturizing.In order to ensure the security of system, to tackle special operation condition, when in the anti-overflow chute 3 of appearance, overflow water is more but do not reach (not reaching the high liquid level of two position meter A6) when trigger relay control cabinet 22 controls automatically, can hand-operated valve B16 in manual-lock chain flushing water pipeline 14, use overflow water to carry out flushing chain.After reply ordinary water level, reopen valve B16, recover normal water supply.
When the two position meter A6 arranged in anti-overflow chute 3 detects that the overflow water of temporary reservoir in anti-overflow chute 3 reaches high liquid level, Control case 22 controls chain wash tub pipe road motor-driven valve B17 closedown, motor-driven valve A8 opens, Pulp pump 11 starts, overflow water enters the section of climbing of dragveyer body 2 by overflow water reclaim line 12, can rinse the chain of dragveyer body 2, achieve dragveyer pulp water inner loop.After anti-overflow chute 3 is emptying, by Control case 22, two position meter A6 controls that Pulp pump 11 stops, motor-driven valve B17 opens, motor-driven valve A8 closes, and recovery is normally rinsed.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and description; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
