Self-starting dustless purifying device

Abstract

The invention discloses a self-starting dustless purifying device. The self-starting dustless purifying device comprises a water spraying pipe and a self-starting control circuit; a primary coil of acurrent transformer L of the self-starting control circuit is connected with a power supply circuit of a load in series, a secondary coil of the current transformer L is connected with an electrolyticcapacitor C1 to be charged by virtue of a rectifying diode D1, the electrolytic capacitor C1 is discharged by virtue of a discharging resistor R2 and a discharging resistor R1, a potential is appliedto a base electrode of an NPN-type triode G1, the NPN-type triode G1 is discharged by virtue of a discharging resistor R3 and a discharging resistor R4 after being switched on, a potential is appliedto a base electrode of a PNP-type triode G2, the PNP-type triode G2 is switched on, a relay electrifying coil is electrified, a switch of a relay is closed, a water pump is started, and the water spraying pipe is started to spray water. The self-starting dustless purifying device can be self-started to realize the spray purification according to the starting of the load, does not require to be handheld to control the spraying, and is simple in control and convenient in use.

Description

technical field [0001] The invention relates to the field of environmental protection construction equipment, in particular to self-starting dust-free purification equipment. Background technique [0002] At present, when the cutting machine cuts the substrate, the dust generated by the cutting seriously affects the construction environment, and the dust is easily inhaled into the human body, affecting the health of construction workers. In order to purify the construction environment of the cutting machine, people use water mist spraying to settle the dust, but the existing water mist spraying starts, that is, another person needs to hold the nozzle and start it while cutting to purify the environment. On the one hand, it is wasteful. Labor, on the other hand, when the cutting machine stops working, the nozzle needs to be closed in addition, and when it is not closed in time, it often causes a waste of water resources. Contents of the invention [0003] The technical pro...

[0002] At present, when the cutting machine cuts the base material, the dust generated by cutting seriously affects the construction environment, and the dust is easily inhaled into the human body, affecting the health of construction workers

In order to purify the construction environment of the cutting machine, people use water mist spraying to settle the dust, but the existing water mist spraying starts, that is, another person needs to hold the nozzle and start it while cutting to purify the environment. On the one hand, it is wasteful. On the other hand, when the cutting machine stops working, the nozzle needs to be closed separately. When it is not closed in time, water resources are often wasted
