Description
Technical Field
The utility model relates to a coke oven dust removal ground station technology, in particular to a dust collector dust collecting pipeline switching device.
Background
The smoke generated when the coke oven is charged or pushed enters the ground dust removing station through the dust collecting pipeline under the suction action of the dust removing fan, and is filtered by the dust remover and then is exhausted. In order to save investment, two coke ovens commonly share one ground dust removal station, and two dust collecting pipelines of the two coke ovens are connected to a main pipeline leading to the dust removal ground station in a tee pipe mode after being converged in the middle. The dust collecting pipelines of the two coke ovens are respectively provided with two pipeline butterfly valves at the three-way pipe, and the aim of switching the dust collecting pipelines of the coke ovens is achieved by switching the two pipeline butterfly valves on and off.
The traditional two coke oven dust collecting pipeline switching butterfly valves are mutually independent and driven by two independent electro-hydraulic push rods. When the dedusting ground station is used for processing the smoke generated by the coke oven No. 1, the butterfly valve of the first dust collecting channel 7 is opened, and the butterfly valve of the second dust collecting channel 9 is closed, and when the dedusting ground station is used for processing the smoke generated by the coke oven No. 2, the butterfly valve of the second dust collecting channel 9 is opened, and the butterfly valve of the first dust collecting channel 7 is closed. When one of the butterfly valves is not opened due to a fault, and the other butterfly valve is closed, at the moment, the suction force generated by the dust removal fan vacuumizes the main dust collection pipe of the dust remover, so that the deformation of the dust collection pipe is caused, and even the suction is shriveled.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dust remover dust collecting pipe switching device prevents the produced accident of pipeline deformation that causes after arbitrary coke oven dust collecting pipe butterfly valve breaks down.
The utility model aims at realizing like this, a dust remover dust collecting pipe switching device, characterized by: at least comprises the following steps: the device comprises a turning plate, a rotating shaft, a connecting rod, an electro-hydraulic push rod and a dust collector dust collecting pipe, wherein the turning plate is fixedly connected to the rotating shaft; the connecting rod is under the effect of electricity liquid push rod, and the pivot rotates and makes to turn over the board and switch between first dust collecting channel to collection dirt main pipe and second dust collecting channel to collection dirt main pipe.
The electro-hydraulic push rod is provided with a sensor, the sensor is electrically connected with the interface of the programmable controller, and the state position of the turning plate is determined according to the signal of the sensor.
The sensor is a displacement sensor or a pressure sensor.
The upper end of the dust collecting pipe tee of the dust remover is provided with a slot, and the connecting rod extends out of the slot.
The utility model has the advantages that: two coke oven dust collecting pipelines share one turning plate and one electro-hydraulic push rod, and only one coke oven dust collecting pipeline is in an open state no matter the electro-hydraulic push rod is in an extending-out position or retracting-back position, so that the state that the two coke oven dust collecting pipelines are both closed can not be generated. If the electrohydraulic push rod is in failure and stops in the extension and contraction process, the dust collecting pipelines of the two coke ovens are not completely closed. Thus, the main dust collecting pipe of the dust collector can not be vacuumized. When the No. 1 coke oven uses the dust removal station, the electric control system controls the electro-hydraulic push rod to retract in place, the turning plate rotates clockwise to a certain angle around the rotating shaft, so that the first dust collection channel is communicated with the main dust collection pipeline, smoke dust of the first dust collection channel enters the main dust collection pipeline of the dust remover through the first dust collection channel, and meanwhile, the other end of the turning plate seals the second dust collection channel; when the 2# coke oven uses the dust removal station, the electric control system controls the electric-hydraulic push rod to extend in place, the turning plate rotates anticlockwise to a certain angle around the rotating shaft, the second dust collection channel is communicated with the dust collection main pipeline, smoke of the second dust collection channel enters the dust collector dust collection main pipeline through the second dust collection channel, and the first dust collection channel is sealed at the other end of the turning plate 1.
