The cross-sectional areas of the four dust collection pipes are gradually increased from top to bottom, and the weight of dust gas flowing out of the outside is larger than that of air, so that the dust gas has a downward falling tendency, and the dust gas can be firstly absorbed by the dust collection pipe with the small cross-sectional area until the dust collection pipe with the largest cross-sectional area is used for absorbing, so that the dust can be completely absorbed by using a step dust collection method.
The dust absorbed by the dust suction pipe will continue to enter the fourth connecting pipe 405 along the wind force, the other end of the fourth connecting pipe 405 is communicated with the second hollow column 404, and the other side of the second hollow column 404 is connected with the three-way pipe 403, so that the wind force entering the three-way pipe 403 will enter the support 401 through the second single pipe 402 and finally precipitate in the collecting bag 40, so as to collect dust impurities.
In the above description, the wind entering the four-way pipe 32 is divided into three streams, one stream of wind is blown in from the air inlet pipe 33, at this time, the wind entering the air inlet pipe 33 is divided into two streams again, one stream of wind enters the cooling bag 46 through the branch pipe 407, so as to cool the outer surface of the cooling bag 46 by using the return wind, and therefore, the floating dust falls on the cooling bag 46 for cooling, so that the density of the cooled dust is far greater than that of the air, and the dust falls down.
The dust exhaust assembly 408 includes inner shell 4081, the outside and the cooling bag 46 fixed connection of inner shell 4081, the both sides of inner shell 4081 overlap with income tuber pipe 33 respectively and go out tuber pipe 49 mutually and establish and be connected, the top fixedly connected with drainage plate 4082 of inner shell 4081 inner wall, the inside fixedly connected with induction coil 4083 of inner shell 4081, one side fixedly connected with electric capacity 4084 of inner shell 4081 is kept away from to induction coil 4083, the inside slidable mounting of inner shell 4081 has roof 4085, the bottom fixedly connected with branch 4086 of roof 4085, the bottom fixedly connected with mount table 4087 of branch 4086.
The other strand of wind flows into the inner shell 4081, and the wind flows along the top of the inner shell 4081 to the other side, because the alternating current flowing through the capacitor 4084 and the induction coil 4083 is supplied from the outside, high-density magnetic force lines are generated in the induction coil, and the metal material contained in the induction coil is cut, wherein the metal material is placed in the holding table 4087, so that the holding table 4087 is lifted upwards and extends into the induction coil 4083 by an outside operator, and the cutting or melting effect on the metal material is achieved. And the space outside the range of the induction coil 4083 and the capacitor 4084 is not affected by the high temperature.
However, a great amount of high-temperature dust is generated in the process of cutting or melting the metal material, at this time, the high-temperature dust can drift upward along the inner shell 4081 until reaching the top of the inner shell, however, the wind blown out by the air inlet pipe 33 moves along the top of the inner shell 4081, so that the high-temperature dust can be blown into the air outlet pipe 49 along with the wind, and the other end of the air outlet pipe 49 is communicated with the collecting bag 40, so that the high-temperature dust in the inner shell 4081 falls into the collecting bag 40 to play a role of keeping the interior of the inner shell 4081 clean and pollution-free. In addition, the drainage plate 4082 fixed on the top of the inner wall of the inner shell 4081 plays a role in carrying out position traction on dust by utilizing wind power.
The wind force blowing into the four dust suction pipes is intense, but the wind force blowing into the air inlet pipe 33 is weak, and the dust in the inner housing 4081 is blown away or re-blown into the induction coil 4083 in order to prevent the wind force from being too large.
In a third embodiment, as shown in fig. 7-9, the sprinkler 48 includes a housing 481, the housing 481 is fixedly connected to the inside of the top platform 47, an inner shell 482 is disposed in the housing 481, water passing pipes 485 are respectively sleeved on the outer sides of the housing 481 and the inner shell 482, top holes 483 are formed in the top of the inner shell 482, a piston rod 484 is slidably mounted in the inner shell 482, the outer sides of the piston rod 484 are respectively inserted in the top of the housing 481 and the inner shell 482, a clamping ring 486 is fixedly connected to the inner side of the housing 481, one end of the clamping ring 486 away from the housing 481 is connected to the inner shell 482, a spring 487 is fixedly connected to the bottom of the clamping ring 486, a through hole needle 488 is fixedly connected to one end of the spring 487 away from the clamping ring 486, a bottom plate 489 is disposed below the through hole needle 488, a bottom plate 489 is provided with a bottom plate 480, a bottom plate 489 is provided on the top of the bottom plate 489, and a sprinkler assembly 4801 is fixedly connected to the bottom of the housing 481.
The piston rod 484 is continuously pulled up and down through external equipment, water is continuously led into the water-through pipe 485, when water flows into the lower part of the piston rod 484 and the piston rod 484 is in an upward operation state, the water flows are accumulated below the piston rod 484, then when the piston rod 484 moves downwards, the piston rod 484 extrudes the water flow below the piston rod 484, and at the moment, the water flows can flow out from the insertion holes 8016 formed in the bottom of the bottom shell 8011 and form water mist so as to play a role in cooling the circulated high-temperature dust. Meanwhile, the temperature of water mist formed by water flow is far lower than the temperature of the rest of the inner shell 4081, so that high-temperature dust accumulated in the inner shell 4081 can move towards the position where the water mist is thrown through the heat transfer effect, and the effects of dust collection, cooling and then blowing away by wind power are achieved.
The top of the piston rod 484 in the downward pressing state is filled with a large amount of water due to the continuous water inlet of the water pipe 485, and as the piston rod 484 moves upward again, it presses the water flow accumulated on the top of the piston rod 484, and the water flows pass through the top hole 483 and then flow downward from the space between the outer shell 481 and the inner shell 482, and simultaneously presses the through hole needle 488 downward in the downward flowing process until the water is extruded from the bottom hole 480, and the extruded water mist also plays a role in dust collection and cooling.
The sprinkler assembly 4801 includes a bottom casing 8011, the bottom casing 8011 is fixedly connected to the bottom of the casing 481, a jack 8016 is provided at the bottom of the bottom casing 8011, a sleeve 8012 is fixedly connected to the outer side of the bottom casing 8011, a rod 8013 is slidably mounted in the sleeve 8012, an open hole ring 8014 is fixedly connected to one end of the rod 8013 away from the sleeve 8012, and a thimble 8015 is fixedly connected to the top of the open hole ring 8014.
When the water flow accumulated in the bottom shell 8011 moves downwards without the piston rod 484, the water flow does not flow out of the jack 8016, because the piston rod 484 forms suction force on the bottom of the piston rod 484 in an upward process, the suction force can not cause the water flow to flow downwards, meanwhile, the suction force can drive the perforated ring 8014 to move upwards, in addition, the embedded rod 8013 connected with the outer side of the perforated ring 8014 is slidably mounted in the sleeve rod 8012, and therefore the perforated ring 8014 can drive the thimble 8015 fixed at the top of the thimble 8015 to move upwards, so that impurities and dust adhered on the jack 8016 are cleaned, and the effect of blocking is avoided. Wherein the split ring 8014 and the socket 8016 are lightweight.
When the piston rod 484 moves upward, the water flowing through the inside of the outer and inner shells 481 and 482 will move the through hole needle 488 downward to remove the tension of the spring 487, thereby cleaning the impurities and dust inside the bottom hole 480. Wherein the spring 487 is always in compression to act as a return to the through-hole needle 488.
