Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 3, a heat treatment quenching flue gas collecting device 10 includes: a cover body 11, a nozzle 12, a fan 13 and an air suction pipeline 14. The nozzle 12 injects a flame-retardant gas into the housing chamber 111. The hood 11 is used for collecting flue gas generated during heat treatment quenching. The nozzle 12 is used for injecting flame retardant gas to avoid potential safety hazards caused by combustion during heat treatment quenching. The fan 13 is used for extracting the flue gas collected in the cover 11 out of the cover 11. The air suction pipe 14 is used for moving the smoke in the cover body 11 to the air suction port of the fan 13. The cover 11 is formed with a cover cavity 111. The enclosure 111 is capable of gathering smoke. The air suction pipeline 14 is communicated with the cover cavity 111 and the fan 13 to enable the fan 13 to suck the smoke in the cover cavity 111.
Further, the cover 11 includes: a fixed cover 112 and a movable cover 113. The movable enclosure 113 has an open position for entry of parts into the movable enclosure 113 and a closed position for closing the opening to prevent fumes generated within the enclosure 11 from escaping the enclosure 11. The movable cover 113 moves between an open position and a closed position relative to the fixed cover 112. When the movable cover 113 is in the closed position, the center of the top of the cover 11 is convex downward and the outer end of the top of the cover 11 is curved downward, and the area between the center and the outer end of the top of the cover 11 is bulged upward to form a top cavity 114. A through hole 15 through which a hanger for hanging parts is passed is formed at the center of the top of the cover 11. The walls of the top chamber 114 are curved to direct the flue gas entering the top chamber 114 so that the flue gas around the periphery of the through-hole 15 moves downwardly. The direction of movement of the fumes is referred to in the direction of the arrows in fig. 1.
Specifically, when the part is heat-treated and quenched, the movable cover 113 is driven to position the movable cover 113 at the open position. At this time, the parts are put into the cover body 11 through the through hole 15 by using the hanger. The hanging piece can be a steel wire rope or other types of hanging pieces used for hanging parts. Then the movable cover body 113 is driven to the closing position, and the part is continuously descended to enter the quenching tank. Flue gas generated after the parts enter the quenching tank moves upwards into the top cavity 114. Part of the smoke in the top cavity 114 moves to the periphery of the through hole 15 under the guidance of the arc-shaped cavity wall of the top cavity 114 and then continues to move downwards. The smoke moving downwards from the periphery of the through hole 15 collides with the smoke moving upwards from the lower part of the through hole 15, so that the moving direction of the smoke below the through hole 15 is changed, and the smoke below the through hole 15 is prevented from continuously moving upwards and overflowing out of the cover body 11 through the through hole 15. Other fumes in the top chamber 114 move through the suction duct 14 to the fan 13 and are drawn by the fan 13. Meanwhile, the nozzle 12 injects flame retardant gas into the cover cavity 111 of the cover body 11 to prevent the oil in the cover body 11 from burning. The structure arrangement can effectively treat the smoke in the cover body 11. After the heat treatment and ignition of the parts are completed, the movable cover 113 is driven to return to the open position again, and then lifted by the hanger and taken out of the cover 11.
As a preferred embodiment, the heat treatment quenching flue gas collection device 10 further includes: an electric motor. The motor drives the movable cover 113 to move relative to the fixed cover 112.
Specifically, the motor drives the movable cover 113 to move between the open position and the closed position.
In a preferred embodiment, the motor drives the movable cover 113 to rotate relative to the fixed cover 112.
As a preferred embodiment, the heat treatment quenching flue gas collection device 10 further includes: a guide rail. The guide rail guides the movable cover 113 to move relative to the fixed cover 112.
In a preferred embodiment, the top chamber 114 is a swivel structure.
As a preferred embodiment, a suction duct 14 is connected to the top of the enclosure 11 to convey the flue gas moving up to the top to the blower 13 for extraction by the blower 13.
As a preferred embodiment, the heat treatment quenching flue gas collecting device 10 comprises a plurality of fans 13.
As a preferred embodiment, several fans 13 are symmetrical with respect to the enclosure 11 to ensure efficient extraction of the fumes.
In a preferred embodiment, the nozzle 12 is provided at the bottom of the cover 11.
As a preferred embodiment, the heat treatment quenching flue gas collection device 10 includes a plurality of nozzles 12 to ensure that the flame retardant gas in the enclosure 11 is sufficient.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
