[0025] The filtering mechanism 6 includes a limit ring 601, a filter element 602, and a magnetic attraction ring 603. The surface of the limit ring 601 is fixedly connected to the inner wall of the air collection hood body 1. The surface of the filter element 602 is in movable contact with the inner wall of the air collection hood body 1. The top of the filter element 602 contacts the bottom of the limit ring 601.

[0026] In this embodiment: After using the air collection hood body 1 to connect the external waste gas treatment device with the external waste gas source, when the waste gas enters the interior of the air collection hood, the waste gas will first pass through the filter element 602 for preliminary filtration, and then enter the external waste gas treatment device for secondary filtration treatment, which can reduce the treatment pressure of the external waste gas treatment device. Since the air collection hood body 1 is made of high-temperature resistant and flame-retardant materials, it can avoid damage to the air collection hood body 1 caused by high-temperature waste gas, and avoid the problem that most of the existing air collection hoods for introducing waste gas into the external waste gas treatment device do not have a structure for preliminary filtration of waste gas, which is not convenient for reducing the treatment pressure of the subsequent waste gas treatment device on the waste gas, and the air collection hood does not have a flame-retardant function, and high-temperature waste gas is likely to damage the air collection hood.

[0027] As a technical optimization scheme of the present utility model, mounting holes 9 are provided inside the fixed disk 2, and the number of the mounting holes 9 is several and they are evenly distributed inside the fixed disk 2.

[0030] In this embodiment: By moving the air collection hood body 1 until the sealing gasket 8 contacts the external waste gas source pipe, and then using an external bolt to pass through the mounting block 5 and thread it with the external waste gas source pipe, the air collection hood body 1 can be connected to the external waste gas source pipe, achieving the effect of conveniently connecting the air collection hood body 1 to the external waste gas source pipe.

[0031] As a technical optimization scheme of the present utility model, a sealing gasket 8 is fixedly connected to the bottom of the air collection hood body 1, and the material of the sealing gasket 8 is fluororubber.

[0032] In this embodiment: After connecting the air collecting hood body 1 with an external waste gas source pipeline, the gasket 8 can seal between the air collecting hood body 1 and the external waste gas source pipeline, achieving the effect of conveniently sealing between the air collecting hood body 1 and the external waste gas source pipeline.

[0033] As a technical optimization scheme of the present utility model, handles 4 are fixedly connected to both sides of the air collecting hood body 1, and pull rings 7 are fixedly connected to both sides of the bottom of the magnetic attraction ring 603.

[0034] In this embodiment: By holding the handle 4, the air collecting hood body 1 can be moved, and by holding the pull ring 7, the magnetic attraction ring 603 can be pulled, achieving the effect of conveniently pulling the air collecting hood body 1 and the magnetic attraction ring 603.

[0035] As a technical optimization scheme of the present utility model, a sound insulation cotton 10 is inlaid inside the air collecting hood body 1, and an observation window 3 is inlaid inside the air collecting hood body 1.

[0036] In this embodiment: By filling the sound insulation cotton 10 inside the air collecting hood body 1, the noise generated by the flow of waste gas airflow inside the air collecting hood body 1 can be reduced, achieving the effect of reducing the waste gas airflow noise.

[0037] As a technical optimization scheme of the present utility model, a corrosion-resistant layer 12 is evenly sprayed on the surface of the air collecting hood body 1, and the material of the corrosion-resistant layer 12 is polysiloxane coating.

[0038] In this embodiment: By spraying a corrosion-resistant layer 12 made of polysiloxane coating material on the surface of the air collecting hood body 1, the air collecting hood body 1 can have the function of corrosion resistance, and the corrosive waste gas with relatively high corrosivity can be prevented from corroding the air collecting hood body 1, achieving the effect of making the air collecting hood body 1 have the function of corrosion resistance.

[0039] As a technical optimization scheme of the present utility model, a wear-resistant layer 11 is evenly sprayed on the surface of the corrosion-resistant layer 12, and the material of the wear-resistant layer 11 is polyurethane wear-resistant coating.

[0040] In this embodiment: By evenly spraying a wear-resistant layer 11 made of polyurethane wear-resistant coating material on the surface of the corrosion-resistant layer 12, the air collecting hood body 1 can have the function of wear resistance, and the particulate matter in the waste gas can be prevented from wearing the corrosion-resistant layer 12 and the air collecting hood body 1, achieving the effect of preventing the particulate matter in the waste gas from wearing the air collecting hood body 1.

[0041] Working principle: First, hold the handle 4 to move the hood body 1, move the hood body 1 until the sealing gasket 8 contacts the external exhaust gas source pipeline, and then use the external bolt to pass through the mounting block 5 and threadedly connect with the external exhaust gas source pipeline to connect the hood body 1 with the external exhaust gas source pipeline. At this time, the sealing gasket 8 can seal the hood body 1 with the external exhaust gas source pipeline, and then use the external bolt to pass through the mounting hole 9 and threadedly connect with the air intake pipeline of the external exhaust gas treatment equipment to connect the hood body 1 with the external exhaust gas treatment equipment. When the exhaust gas enters the hood, the exhaust gas The filter element 602 will be initially filtered through the filter element 602, and then enter the external exhaust gas treatment equipment for re-filtration treatment, which can reduce the treatment pressure of the external exhaust gas treatment equipment. Through the observation window 3, it can be judged whether the filter element 602 inside the air hood body 1 needs to be replaced. When the filter element 602 needs to be replaced, it is only necessary to remove the external bolts at the mounting block 5, and then hold the pull ring 7 to pull the pull ring 7 until it is out of the magnetic attraction state with the inner wall of the air hood body 1. At this time, the filter element 602 can be removed from the inside of the air hood body 1 for replacement. Since the air hood body 1 is made of high-temperature resistant and flame-retardant materials, it can avoid high-temperature exhaust gas. By damaging the air collecting hood body 1, it is possible to avoid the problem that most of the existing air collecting hoods that introduce exhaust gas into external exhaust gas treatment equipment do not have a structure for preliminary filtration of exhaust gas, which is inconvenient to reduce the subsequent exhaust gas treatment pressure on the exhaust gas, and the air collecting hood does not have a flame retardant function. High-temperature exhaust gas can easily cause damage to the air collecting hood. By spraying a corrosion-resistant layer 12 of polysiloxane coating material on the surface of the air collecting hood body 1, the air collecting hood body 1 can be made corrosion-resistant, which can avoid the corrosion of the air collecting hood body 1 by highly corrosive exhaust gas. By evenly spraying polyurethane wear-resistant coating material on the surface of the corrosion-resistant layer 12 The wear-resistant layer 11 can make the air hood body 1 wear-resistant and prevent the particles in the exhaust gas from wearing the corrosion-resistant layer 12 and the air hood body 1. By filling the air hood body 1 with sound insulation cotton 10, the noise generated by the flow of exhaust gas inside the air hood body 1 can be reduced. It should be noted that the exhaust gas treatment equipment is an existing mature technology that has been published and will not be elaborated here. It should be noted again that the flow direction of the exhaust gas source is toward the filter element 602. Therefore, the magnetic ring 603 will only press the filter element 602 tightly due to the flow direction of the airflow, and the magnetic ring 603 will not accidentally separate from the magnetic state of the air hood body 1.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
