Example 1

The multi-unit dust removing equipment mainly comprises the following main components:

the device comprises a dust removal box body 1, a fan bin 2, a pulse air pocket chamber 3, a buffer bin 4, a filtering bin 6, a settling bin 7, a dust absorption pipeline, a chimney 8, a discharging assembly 9 and an existing electric control system, namely a controller.

These assemblies all have a viewing port and an access port.

(1) The dust separator is provided with access doors per compartment (these access doors must not be opened when the device is in operation).

(2) Each filter bin 6 of the dust remover is provided with a pulse device access hole for checking the dust cleaning device.

(3) The top plate of the fan bin 2 of the dust remover is provided with an access hole, so that the fan can be overhauled.

The working principle of the multi-unit dust removing equipment is as follows: the fan bin 2 is arranged outdoors, and the fan bin 2 is connected with the dust collecting branch pipelines of each room through the dust collecting pipelines embedded into the wall. The indoor waste gas is conveyed to the dust absorption branch pipeline through the dust absorption hose, then is collected in the main dust absorption pipeline, and is conveyed to the filtering bin 6 through the main dust absorption pipeline. Due to the inertia effect, the dust directly falls to the sedimentation bin 7, and the effect of pre-collecting dust is achieved. The light and fine dust is filtered by the pulse filter bag in the filter bin 6, and the filtered air passes through the pulse air bag chamber 3 and the fan bin 2 and finally enters the chimney 8 to be discharged after reaching standards at high altitude. The pulse air bag chamber 3 guides compressed air to reversely spray the filter bag by using an online pulse spraying and blowing system (prior art), and dusts on the surface of the pulse filter bag of the filter bin 6 are shaken down to the filter bin 6 by using the rapid expansion vibration and the directional airflow of the filter bag during spraying and then are discharged by the discharging assembly 9. When the fan is closed, the pulse ash-cleaning system (in the prior art) starts to automatically close within a certain time according to a designed program, so that the cleaning of the dust-removing filter bag is ensured.

After a start key of the controller is pressed, the equipment is started in modules according to a program in a set sequence, and finally the whole normal operation is started. One key starts dust collecting equipment, and equipment will start the high pressure positive blower in fan storehouse 2 earlier and unload No. one of subassembly 9 at last, and high pressure opens and stops the time delay back (according to actual conditions and decide, and the time also can be set for by the staff in advance), starts other screw feeder of subassembly 9 of unloading again and unloads, starts the time delay back (the time also can be set for in advance in the industrial control unit by the staff), will start the draught fan, and equipment gets into normal operating. After the stop button is pressed by a worker, the device firstly closes the draught fan, closes the auger except the last unloading and unloads after the stop delay (the time can be set by the worker in advance according to the actual condition), closes the high-pressure draught fan and unloads the last after the high-pressure start-stop delay (the time can be set by the worker in advance according to the actual condition), and stops the operation of the device.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
