The utility model will be further described with reference to the drawings and specific examples to aid in understanding the context of the utility model. The method used in the utility model is a conventional method unless specified otherwise; the raw materials and devices used, unless otherwise specified, are all conventional commercial products.
The utility model provides a linkage device of a degassing and smoke exhausting system, which is shown in figures 1 to 4, and comprises an introduction device 1, a collector 2, a cooling filter layer 3, a collecting filter layer 4, a centrifugal fan 5 and a discharge pipeline 6; the collector 2 is hollow and is used for placing the cooling filter layer 3 and the collecting filter layer 4 and storing the flue gas brought by the introduction device 1 and scattered residues after cooling.
The introduction device 1 is in communication with one end of the collector 2 and the discharge duct 6 is in communication with the other end of the collector 2, i.e. flue gas enters the collector 2 from the introduction device 1 and is discharged from the discharge duct 6.
The cooling filter layer 3 is fixedly arranged in the collector 2, the collecting filter layer 4 is fixedly arranged in the collector 2 and positioned at the rear of the cooling filter layer 3, active fluoride, chloride and the like are contained in the flue gas, the flue gas can be better collected only by cooling and filtering, and slag which is not cooled and filtered is collected by the collecting filter layer 4, so that the cooling filter layer 3 is required to be positioned in front of the collecting filter layer 4.

The centrifugal fan 5 is fixedly arranged on the collector 2 and is communicated with the collector 2, the main body of the centrifugal fan 5 is arranged outside the collector 2, and only the air outlet is connected into the collector 2, so that the main body structure of the centrifugal fan 5 is prevented from being polluted by smoke.
The leading-in device 1 includes cover type concentrator 7 and air duct 8, and cover type concentrator 7 is loudspeaker form, and cover type concentrator 7's osculum end and air duct 8 intercommunication, and air duct 8's the other end and collector 2 intercommunication, loudspeaker form cover type concentrator 7's big mouth end coverage area is great, helps leading in air duct 8 with the flue gas is concentrated.
The air duct 8 comprises a flexible section which is a corrugated tube structure presenting a continuous meandering shape in the cross section of the tube wall for bending and changing the direction of the hood-type concentrator 7 so that it is better arranged above the smoke outlet of the production device.
The cooling filter layer 3 is a grid type 316 stainless steel plate, compared with other structural forms, the contact area of the cooling filter layer 3 with hot smoke is larger, the purpose of the cooling filter layer 3 is to be in contact with active slag such as fluoride and chloride in the hot smoke, when the slag contacts the cooling filter layer 3, the slag which is originally active and exists in the hot smoke becomes inactive solid, the solid is scattered in the collector 2, heat absorbed by the cooling filter layer 3 is absorbed by the rear centrifugal fan 5, and the first smoke discharge filtration is completed. During the filtration process, the cooling filter layer 3 directly contacts the hot flue gas rich in pollutants such as fluoride, oxide, chloride and the like, so that the 316 stainless steel plate with high corrosion resistance is adopted.
The collecting filter layer 4 is formed by sleeving a plurality of high-temperature-resistant glass fiber cloth bags on a preset support, slag which is still not completely filtered after passing through the cooling filter layer 3 is filtered again by the glass fiber bags, and the filtered slag directly falls into the glass fiber bags to complete secondary smoke discharging filtration, so that the filtering effect is effectively improved.

Working principle: the cover type concentrator 7 led into the device 1 is covered above the smoke generating device, the temperature of hot smoke generated in the aluminum alloy degassing process is higher, and the molecular heat power is high, so that the aluminum alloy can spontaneously move upwards. The air outlet of the centrifugal fan 5 faces the exhaust pipeline 6, so negative pressure is generated in the opposite direction of the air outlet of the centrifugal fan 5 during starting, and hot smoke moves to the hood-type concentrator 7 above the smoke outlet under the action of self thermal power and the negative pressure of the centrifugal fan 5. The hood-type concentrator 7 concentrates the flue gas and then sends the flue gas into the air duct 8, the flue gas enters the collector 2 through the air duct 8, the flue gas in the collector 2 firstly passes through the cooling filter layer 3, active slag such as fluoride and chloride in hot flue gas becomes inactive because of temperature reduction and the slag is scattered in the collector, and the heat absorbed by the cooling filter layer 3 is absorbed by negative pressure generated by the rear centrifugal fan 5. The active slag which is not filtered by the cooling filter layer 3 continues to advance along with the flue gas, and the residual active slag in the hot flue gas is directly blocked and collected by the collecting filter layer 4 positioned behind the cooling filter layer 3, so that the flue gas filtering is finished. The centrifugal fan 5 then pushes the remaining flue gases into the discharge duct 6.
