A protrusion is provided on the outer wall of the connecting tube 3, and a guide groove is provided on the protrusion. An insert plate 37 is slidably inserted in the guide groove, and the protruding end of the insert plate 37 is further inserted through the insert ring 361 to keep the cleaning door 36 closed.
[0028] A corner is provided on the connecting pipe 3 at a position corresponding to the position between the second sleeve 52 and the filter screen 4, so that the connecting pipe 3 is bent into a vertical section extending vertically upward, and the filter screen 4 is arranged in the vertical section. A pipe cover 38 is screwed at the position of the corner.
[0029] The operating principle of the utility model is as follows:
[0030] like Figures 1 to 3As shown, before use, a guide rail 11 is first arranged on the outside of the fire cutting machine 1, and a pulley 12 rotating on the guide rail 11 is arranged on the bracket 10, and the pulley 12 is connected to the output end of the power motor 13 fixed on the bracket 10, so that the bracket 10 and the fan 2 arranged on the bracket 10 can move on the guide rail 11 under the drive of the power motor 13, and one end of the fan 2 is connected to a connecting pipe 3, and the other end is connected to an exhaust pipe (not marked), and one side of the connecting pipe 3 is connected to a wind hood 30, which is located directly above the cutting position of the fire cutting machine 1. As the cutting proceeds and the wind hood 30 moves synchronously with the fire cutting machine 1, the air containing a large amount of dust generated by the cutting can be sucked out in time; in order to facilitate the movement of the bracket 10 in the front and rear directions of the guide rail 11, the power motor 13 used is preferably a servo motor.
[0031] When in use, the sucked air first flows through the position of the first sleeve 51, and firstly, the large particles of dust in the air are screened out at the position of the screen 6, and then the pumping valve 321 is opened at the same time to pump out the water in the water tank 31, and then the water is simultaneously diverted to the first drain pipe 331 and the second drain pipe 332 through the outlet pipe 32 and the three-way valve 33, and sprayed into the first sleeve 51 and the second sleeve 52 by the nozzles 34 at the corresponding positions. Since the inhaled air has a certain speed, the large particles of impurities in the sucked air will partially rush through the screen 6 on the first sleeve 51 and reach the position of the second sleeve 52 under the drive of the speed. At this time, the screen 6 on the second sleeve 52 continues to further screen out the large particles of impurities, and coupled with the water spraying effect in the two sleeves, the impurity content in the sucked air is greatly reduced.
[0032] After two screening and spraying dust reduction operations, the sucked air reaches the corner position between the second sleeve 52 and the filter screen 4 on the connecting pipe 3. At this time, the connecting pipe 3 is bent into a vertical section extending vertically upward. The filter screen 4 is arranged in the vertical section to filter out small particles of impurities contained in the sucked air again, further reducing the impurity content in the air, and finally discharged from the exhaust pipe connected to the fan 2.
[0033] In addition, a corner is provided on the connecting pipe 3 at a position corresponding to the second sleeve 52 and the filter screen 4, so that the connecting pipe 3 is bent into a vertical section extending vertically upward, and the upper end of the vertical section is connected to the exhaust pipe. The setting of the vertical section is more conducive to the falling and collection of filtered dust.
[0034] It should be noted that in order to prevent the sprayed water from flowing out of the sleeve and dripping on the wind hood 30, baffles 53 are provided on the two sleeves, each baffle 53 is fixedly provided with a screen 6, and a guide plate 54 is obliquely arranged between the two baffles 53 of each sleeve, so that the sprayed water can flow into the return pipe 35 through the guide plate 54, and flow back to the water tank 31 through the return pipe 35 to achieve the purpose of recycling; wherein, some water particles will move out of the sleeve with the air flow, but due to the high temperature use environment of the fire cutting machine 1, under the premise of not generating large water accumulation, the high temperature environment can evaporate this part of the water in time, and will not cause the accumulated water to flow out of the wind hood 30; it occupies a small space, has a simple and compact structure, and also avoids the influence of installation interference.
[0035] At the same time, there will be residual large particles of impurities accumulated at the position between the two sleeves. In order to facilitate timely cleaning, a cleaning door 36 is hingedly provided on the connecting tube 3 at the position corresponding to the position between the first sleeve 51 and the second sleeve 52. The non-hinged end of the cleaning door 36 is provided with an insert ring 361, and a protrusion is provided on the outer wall of the connecting tube 3. A guide groove is provided on the protrusion, and an insert plate 37 is slidably passed through the guide groove. The protruding end of the insert plate 37 is further passed through the insert ring 361 to keep the cleaning door 36 closed. When the cleaning door 36 needs to be opened, just pull out the insert plate 37; in order to avoid air leakage, a sealing ring (not marked) is wrapped around the edge of the cleaning door 36.
[0036] Similarly, at the corner position of the connecting pipe 3, it is preferred to screw a pipe cover 38 at the lower end of the vertical section, which simplifies the closed structure and facilitates opening. Dust will not leak out when the pipe cover 38 is opened, and it is also convenient to sweep out accumulated dust in the horizontal direction, thereby improving the cleaning management efficiency at the use site of the fire cutting machine 1.
[0037] In order to prevent the pulley 12 from derailing on the guide rail 11, a limit block 14 is provided on the guide rail 11 to ensure safe use.
