Further, described dust arrester comprises the electromagnetic impulse valve that is arranged on dust filter, and electromagnetic impulse valve is connected with controller with air compressor machine respectively.

Further, also comprise the alarm that is connected with controller, controller is controlled alarm equipment alarm according to the signal of sensor output.

Further, the power switch of described blower fan is connected with controller, and controller comes conducting or disconnecting power switch according to the signal of described sensor output.

Further, described air cleaner is the cocoanut active charcoal filter.

Further, described dust filter is polyester fiber overlay film cartridge filter.

Further, be provided with dirt-collecting box below described dust filter.

Further, described sensor is the digital display pressure sensor.

Technique scheme has following beneficial effect at least: the utility model is provided with by adopting sensor and the dust arrester that is connected with controller respectively on dust filter, controller triggers the dust arrester action according to the signal of sensor output, make dust collection equipment have automatic dedusting function, avoided plugged filter, the effect that improved dust suction, eliminates the unusual smell; Fan power is connected with controller with alarm, and controller is controlled alarm equipment alarm and fan power switch circuit breaking according to the signal of described sensor output, has avoided blower fan to cause burning because of plugged filter, has extended service life.

The specific embodiment

Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the application can make up mutually.Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1 and Figure 2, the dust collection equipment of the utility model embodiment comprises frame 1, controller 2, blower fan 3, air cleaner 4, dust filter 5, sensor 6, dust arrester and alarm.

Frame 1 is the cabinet shape, is used for supporting whole dust collection equipment.

Controller 2 is arranged on the position, upper right side of frame 1; it adopts the PLC automation control circuit to be connected with sensor 6, dust arrester, alarm and fan power switch respectively; being used for controlling dust arrester action, alarm equipment alarm and fan power switch according to the detection signal of sensor 6 disconnects; avoid burning with protection blower fan 3, reminding user is in time cleared up air channel and filtration system.

Blower fan 3 is arranged on the position, upper left side of frame 1, and it adopts high pressure positive blower, and the negative pressure of generation can reach 270mbar, with the smoke inhalation that produces in laser cutting machine work in dust collection equipment; Air cleaner 4 has two, is arranged on respectively the centre position of frame 1, and it adopts the cocoanut active charcoal filter, further filtering dust not only, and can adsorb poisonous and harmful peculiar smell in smog, reach the effect that eliminates the unusual smell; Dust filter 5 is arranged on the below of frame 1, it adopts polyester fiber overlay film high-accuracy high-efficiency cartridge filter, but high-efficient filter chalk dust removing, filtering accuracy reaches 0.3um, certainly, as another embodiment, the quantity of described air cleaner 4 and dust filter 5 can be decided according to actual conditions, has arrived economical and practical, dedusting and has eliminated the unusual smell that effect is good is purpose; Sensor 6 is arranged on dust filter 5 inside, and it adopts corrosion resistance and the good digital display pressure sensor of long-time stability, is used for the air pressure of dust filter 5 inside is monitored, and Monitoring Data is transferred to controller 2.

dust arrester comprise be arranged on dust filter 5(polyester fiber overlay film high-accuracy high-efficiency cartridge filter) electromagnetic impulse valve 7 on end face, electromagnetic impulse valve 7 is connected with air compressor machine with controller 2 respectively, controller 2 control electromagnetic impulse valves 7 are opened like this, the powerful air-flow that outside air compressor machine is carried is blown in polyester fiber overlay film high-accuracy high-efficiency cartridge filter in the opposite direction with dust filter 5 internal air stream, powerful air-flow spreads and makes cartridge filter produce shake along the radial direction of cartridge filter, the dust that is accumulated in cartridge filter will break away from cartridge filter, in order better to clean dust collection equipment, be provided with dirt-collecting box 8 below dust filter 5, the dust of shaking off like this is scattered in 8 li of dirt-collecting box, certainly, as another kind of embodiment, dust arrester also can be mounted in the centrifugal motor on dust filter 5 etc., can produce above-mentioned beneficial effect equally.

During use, blower fan 3 energising work, the negative pressure that in dust collection equipment, place, the inlet scoop in air channel produces is 270mbar, with the smoke inhalation that produces in laser cutting machine work in dust filter 5, through dust filter 5(polyester fiber overlay film high-accuracy high-efficiency cartridge filter) filtering dust, filtering accuracy reaches 0.3um, air after filtration is more successively by two cocoanut active charcoal filters, further filtering dust, and can adsorb poisonous and harmful peculiar smell in smog, reach the effect that eliminates the unusual smell, discharge from the top of frame 1 finally by crossing the air that purifies.

monitor and monitor signal is transferred to controller 2 by the air pressure in 6 pairs of dust filters of sensor 5 in the whole course of work, accumulation along with the working time, when the dust that sucks accumulates on dust filter 5, when the gas-flow resistance in dust filter 5 reaches the first setting value of sensor 6, controller 2 triggers the dust arrester action automatically, by electromagnetic impulse valve 7, the powerful air-flow that outside air compressor machine produces is blown in polyester fiber overlay film high-accuracy high-efficiency cartridge filter in the opposite direction with dust filter 5 internal air stream, avoid dust filter 5 to stop up, improved dust suction, the effect that eliminates the unusual smell, when the excessive obstruction dust filter 5 of Dust Capacity that sucks, when the resistance in dust filter 5 reaches the second setting value of sensor 6, controller 2 automatic disconnection fan power switches are also controlled alarm equipment alarm, and protection blower fan 3 is avoided burning, reminding user cleaning pipeline and filtration system.

The above is the specific embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
