The dust collecting device and the dust collecting vehicle of the present disclosure will be further described in detail by the specific operation and use steps of the dust collecting vehicle.
In the using process, the dust collecting vehicle is stopped to one side of the factory dust collecting bin, and the side, provided with the dust collecting device, of the dust collecting vehicle faces the factory dust collecting bin.
First, whether the spark detector (the smoke detector 22 and the light detector 23) and the shower system are in the open state is observed, the car door 27 is opened in a state where the normal operation is ensured, the dust collecting pipe 111 stored in the storage box 25 is taken out, and the dust collecting pipe 111 is pulled out of the abutting dust collecting place. The blower device 13 is opened by an operator to make the interior of the dust collecting bin 12 in a negative pressure state, so that dust is sucked in. During the suction process, the dust enters the dust collection bin 12 through the filter device 112 in the dust collection pipe 111 and the two-way explosion-proof valve 113 in sequence. An airflow blocking device 121 is arranged above the inlet of the dust collection pipe 111 of the dust collection bin 12, so that the forming range of dust cloud is suppressed, and meanwhile, the spraying device 17 and the spark detector are prevented from being blocked.
The heavier dust can fall naturally under the action of the airflow blocking device 121, and the fine dust which is easy to form dust cloud is collected for the second time through the dust removing device 14, so that the dust collecting efficiency can be improved. The fine dust enters the interior through the air inlet 141 of the dust removing device 14, a partition plate 144 is arranged in the middle of the dust removing device 14 to form an upper dust remover part and a lower dust remover part so as to improve the dust removing efficiency, a discharge port 142 is formed in one side of the lower dust remover part, which is close to the dust collecting bin 12, the fine dust is conveyed into the dust collecting bin 12, the accumulation condition of the dust at the position is observed through an observation window 203, and the dust can be manually moved under the condition of ensuring safety.
The dust-free exhaust gas which has passed through the dust removal device 14 is passed through the fan device 13 into the exhaust pipe 19, through which it is discharged into the air. The exhaust pipe 19 extends the pipe orifice upwards to the air at the rear side of the carriage body, so that secondary pollution is avoided.
The dust collection can be completed through the steps, and meanwhile, the accumulated amount of dust in the dust collection vehicle can be noticed through the observation window 203. If dust accumulates at the discharge port 142 of the bag-type dust collector 14, the dust collection pipe 111 is taken out and placed in the air, the fan device 13 is closed after no obvious dust cloud exists in the dust collection bin 12, the accumulated dust at the discharge port 142 is cleaned through a manhole, and at the moment, the fan device 13 can be continuously opened for dust collection. After the dust is collected, the fan device 13 is closed, the dust collection pipe 111 is stored in the storage box 25, and the box door 27 is closed.
Preferably, a rotatable three-port discharge device is provided at discharge port 142 to avoid dust accumulation at discharge port 142.
In the transportation process after dust collection is finished, the ventilation fan 202 is turned on to prevent the volatile dust from releasing inflammable gas. If the summer is hot, the water circulation cooling system can be opened to avoid smoldering caused by overhigh temperature in the carriage body 20, and the water circulation cooling system can not be opened if the ambient temperature is low. During normal transportation of the dust collection vehicle, static electricity is discharged through the prepared grounding metal chain 18.
After the dust is transported to the processing site, the dust cleaning hole 122 at the bottom of the carriage body 20 is opened to discharge the dust out of the carriage body 20, and manual assistance can be performed through the personnel entrance 204. After the dust is discharged, the dust is cleaned through the personnel inlet 204, and the lower part of the circumferential wall of the dust collection bin 12 is in a slope type, so that the dust collection bin is convenient to clean.
