Description
Technical Field
The invention relates to the technical field of dust removal equipment, in particular to a dust removal device of a laser cutting machine.
Background
The laser cutting is to irradiate the workpiece with high-power-density laser beam to melt and vaporize the irradiated material quickly, and simultaneously blow off the molten material with high-speed airflow coaxial with the laser beam, thereby realizing the cutting of the workpiece.
In laser vaporization cutting, under the heating of a high power density laser beam, about 40% of the material vaporizes into vapor and disappears, and 60% of the material is blown away from the bottom of the cutting slit as a jet by an auxiliary gas and combined with fine particles in the air to form dust. In the laser melting cutting, when the power density of an incident laser beam exceeds a certain value, the material at the irradiated part begins to evaporate to form a hole, and the material around the light speed is melted; the secondary gas flow, coaxial with the beam, then entrains the surrounding molten material, forming soot. In laser oxidation cutting, the surface of a material is quickly heated to an ignition temperature under the irradiation of a laser beam, then the material and oxygen undergo a violent combustion reaction to release a large amount of heat, so that small holes filled with steam are formed in the material, the peripheries of the small holes are surrounded by molten metal walls, and the steam and molten substances are taken away by auxiliary air flow and float in a workshop to form dust and smoke.
By above can know that no matter which kind of laser cutting all can produce the smoke and dust, and contain granule dust and a large amount of harmful object in these smoke and dust, if do not take out to the smoke and dust that laser cutting produced, not only be unfavorable for the operation of laser cutting equipment, still can greatly cause harm to human health.
Common dust collector is sack dust collector among the prior art, sack dust collector includes the cabinet body, the cabinet body is including the air exhaust chamber of mutual separation, clean room and dirt collecting chamber, install the fan in the air exhaust chamber, install the filter bag in the clean room, the dirt case is stored up to the installation in the dirt collecting chamber, it has inlet scoop (being located the dust collecting chamber) and air outlet (being located the air exhaust chamber) to open on the cabinet body, in use, the fan starts, the inlet scoop inhales the internal of cabinet through the smoke and dust that external aspiration channel produced laser cutting, the dust in the smoke and dust is blockked by the filter bag and falls to storing up in the dirt case when passing through the filter bag, then discharged through the air outlet by filterable gas.
The dust removal device can meet certain dust removal requirements, but has the following problems:
firstly, after the filter bag is used for a certain time, the filter bag is easily full of dust so as to block the filter holes of the filter bag, and the whole dust removal device cannot normally operate.
Secondly, in laser cutting and the dust removal, the dust storage box is full of dust very easily, nevertheless is located the cabinet body because of the dust storage box, and the workman is difficult in time to discover, and in case the dust storage box is full of collection, then in dust collector continues the start, originally lie in the dust storage box during the dust can be inhaled the filter bag for the filtration pore of filter bag blocks up, and whole dust collector also will unable normal work.
Thirdly, the existing dust removing device can only play a role of dust removal, but harmful gas generated by laser cutting cannot be absorbed, and the harmful gas is directly discharged into the atmosphere to form air pollution.

The second embodiment is basically as shown in fig. 6, and the second embodiment is modified on the basis of the first embodiment as follows: an elastic part 10 is connected between the bottom of the collecting box 8 and the bottom of the cabinet body 1, the elastic part 10 adopts a spring, an alarm is installed on the cabinet body 1, the alarm is connected with a button switch 20, and the button switch 20 is fixed on the cabinet body 1 at the bottom of the collecting box 8 through a screw.
The specific implementation process is as follows:
with the dust in the collecting box 8 increasing continuously, the collecting box 8 overcomes the elasticity of the elastic piece 10 (namely, the spring) and moves downwards until the dust collected in the collecting box 8 is heavy enough and presses the button switch 20, and then the alarm is triggered to give an alarm, so that a worker can replace the collecting box 8 in time after hearing the alarm.
The other implementation contents of the second embodiment are the same as those of the first embodiment.
EXAMPLE III
The third embodiment is basically as shown in fig. 7, and the third embodiment is continuously improved on the basis of the second embodiment, and specifically as follows: a purification unit is further installed in the dust chamber 13, the purification unit comprises an unwinding roller 30 and a winding roller 40, the winding roller 40 is driven by an external motor, a plurality of activated carbon bags 60 which are sequentially connected are wound on the unwinding roller 30 (namely, the activated carbon bags 60 are connected into a belt shape, and then the belt-shaped activated carbon bags 60 are wound on the unwinding roller 30), and the winding roller 40 can wind the activated carbon bags 60 which are unwound from the unwinding roller 30; a plurality of guide rollers 50 are rotatably connected in the cabinet body 1 in which the dust removing chamber 13 is positioned, and a plurality of connected activated carbon bags 60 are waved after being wound around the guide rollers 50; the activated carbon bag 60 is positioned between the top of the dust removal bag 3 and the communication hole of the partition plate at the top of the dust removal chamber 13.
In the third embodiment, in order to avoid the influence of the guide rod 17 and the lead screw 16 on the activated carbon packet 60, a fixing plate is added on the side wall of the cabinet body 1, the fixing plate is fixed on the side wall of the cabinet body 1 through screws, the tops of the guide rod 17 and the lead screw 16 are connected on the fixing plate, and the fixing plate is located below the wind-up roll 40 and the wind-down roll 30.
The specific implementation process is as follows:
utilize wind-up roll 40 and unreel roller 30's cooperation for activated carbon package 60 constantly removes gradually, and the activated carbon package 60 that has absorbed harmful gas is constantly rolled up to wind-up roll 40 on, and new activated carbon package 60 is constantly emitted so that to the timely absorption of harmful gas in the clean room 13, avoids harmful gas directly to discharge polluted air in the atmosphere.
The other implementation contents of the third embodiment are the same as those of the second embodiment.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
