Quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature, kept warm for a period of time, so that it is fully or partially austenitized, and then martensitic at a cooling rate greater than the critical cooling rate. At present, the quenching process mainly uses coolant for rapid heat absorption, and a large amount of steam will be generated during the heat absorption process. If it is left unchecked, it will not only cause corrosion to the surface of the external equipment, but also waste water resources in vain, resulting in a very serious waste of water resources. The current main method is to recover water by extracting water vapor, but this recovery method has a small recovery area, a very limited recovery efficiency, and requires a large amount of kinetic energy and a long condensation process, resulting in low recycling efficiency.

A longitudinal side guide rail 4 is fixedly installed on the outer side surface of the translation adjustment seat 3, and a lateral lifting seat 5 is movably installed on the end of the longitudinal side guide 4 near the horizontal frame 1. An arc-shaped external air guide cover 6 is movably installed on the outer side surface of the lateral lifting seat 5, and three fixed drive guide blades 7 are installed on the arc surface of the lower end of the arc-shaped external air guide cover 6.

[0029] Working principle: The arc-shaped external air guide cover 6 is translated along the lateral translation guide rail 2 through the translation adjustment seat 3, and then lifted and lowered along the longitudinal side guide rail 4 through the lateral lifting seat 5, and then the arc-shaped external air guide covers 6 located on both sides of the horizontal frame 1 are manually flipped, and then the arc-shaped external air guide covers on both sides are fixed and assembled.

[0030] In order to cooperate with lateral adjustment, the lateral translation guide rail 2 is movably equipped with an electrically controlled transverse screw rod 8, and the translation adjustment seat 3 is movably assembled with the lateral translation guide rail 2 by being sleeved on the electrically controlled transverse screw rod 8 through a transverse internal threaded assembly block 9 on the side wall of the assembly surface.

[0031] In order to cooperate with the lifting and lowering adjustment, the longitudinal side guide rail 4 is movably equipped with an electrically controlled longitudinal screw rod 10, and the lateral lifting seat 5 is movably assembled with the longitudinal side guide rail 4 by being sleeved on the electrically controlled longitudinal screw rod 10 through the longitudinal internal thread assembly block 11 on the side wall of the assembly surface.

[0032] The electrically controlled transverse screw rod 8 and the electrically controlled longitudinal screw rod 10 are both prior art. Both the electrically controlled transverse screw rod 8 and the electrically controlled longitudinal screw rod 10 are adjusted by rotation to control the horizontal internal thread assembly block 9 to translate on the electrically controlled transverse screw rod 8 and the longitudinal internal thread assembly block 11 to rise and fall on the electrically controlled longitudinal screw rod 10 respectively.

[0033] In order to cooperate with lateral telescopic movement, a bottom telescopic groove 12 with a lateral opening is opened on the inner curved surface of the curved external air guide cover 6 on one side of the fixed driving guide blade 7, and an electrically controlled lateral telescopic cover 13 is slidably installed inside the bottom telescopic groove 12, and a movable driving guide blade 14 is installed on the lower surface of the electrically controlled lateral telescopic cover 13.

[0034] In order to cooperate with the hydraulic drive, an overhead high-pressure flow channel pipe 15 is opened inside the arc-shaped external guide cover 6 above the connecting end of the fixed drive guide blade 7, and a built-in hydraulic drive impeller 16 is movably installed inside the overhead high-pressure flow channel pipe 15. A bottom drive gear 17 for driving the fixed drive guide blade 7 and the movable drive guide blade 14 is axially installed on the lower surface of the built-in hydraulic drive impeller 16.

[0035] The purpose of using hydraulic drive is to improve heat exchange performance and extend the service life of the equipment.

[0036] The fixed driving guide vanes 7 and the movable driving guide vanes 14 are both made of metal heat-conducting material, and can exchange the internal temperature with the internal temperature of the top high-pressure flow channel pipe 15 through the bottom driving gear 17 .

[0037] In order to cooperate with the fixed drive guide blade 7 and the movable drive guide blade 14 for internal guide, an inner condensation flow channel 18 is provided inside the arc-shaped external guide cover 6 on one side of the fixed drive guide blade 7. The inner condensation flow channel 18 passes through the bottom telescopic groove 12 and is connected to the inside of the electrically controlled lateral telescopic cover 13.

[0038] The inner condensation flow channel 18 is opened on one side of the assembly end of the fixed driving guide blade 7 and the movable driving guide blade 14. The water vapor at the bottom is introduced into the inner condensation flow channel 18 through the rotation of the fixed driving guide blade 7 and the movable driving guide blade 14, and then introduced into the water tank located on the inner bottom surface of the horizontal frame 1 through the condensation pipe at the bottom of the arc-shaped external guide cover 6.

[0039] After the arc-shaped external air guide covers on both sides of the horizontal frame 1 are fixed to each other, the inner condensing flow channels 18 and the top high-pressure flow channel pipes 15 inside the arc-shaped external air guide covers on both sides are fixedly connected.

[0040] In order to cooperate with telescopic adjustment, the electrically controlled lateral telescopic cover 13 includes an internal telescopic cover shell 131 slidably assembled inside the bottom telescopic groove 12 and a lateral hydraulic control support rod 132 fixed on the side wall of the arc-shaped external air guide cover 6.

[0041] The lateral hydraulic control strut 132 is connected to the interior of the overhead high-pressure flow channel tube 15 through the lateral electric control valve of the prior art, and the telescopic adjustment is performed using the high-pressure liquid inside the overhead high-pressure flow channel tube 15. The top of the extended end of the lateral hydraulic control strut 132 is fixedly connected to the inner side of the internal telescopic cover shell 131.

[0042] In order to cooperate with automatic control, lateral humidity sensor controllers are installed on both side walls of the arc-shaped external air guide cover 6. According to the real-time humidity value sensed, the position of the internal telescopic cover 131 is adjusted to expand the range.

[0043] In order to facilitate switching of connections, a first internal guide channel 19 and a second internal guide channel 20 that cooperate with the inner condensation flow channel 18 are opened inside the internal telescopic cover shell 131, and the two side walls of the internal telescopic cover shell 131 are elastically equipped with sliding closing cover plates 21 at the channel openings on both sides of the first internal guide channel 19, and the outer side surface of the sliding closing cover plate 21 has an outwardly protruding external control strip 22.

[0044] When the internal telescopic cover 131 is telescoped, it is squeezed by the external control strip 22 to slide and adjust, thereby controlling the opening and closing of the first internal guide channel 19.

[0045] In order to cooperate with the upper end transmission, an upper transition groove 23 is opened on the upper surface of the internal telescopic cover 131, and switching gears 24 that cooperate with the bottom driving gear 17 are movably installed on both sides of the upper transition groove 23.

[0046] The lateral hydraulic control strut 132 controls the internal telescopic cover 131 to slide and adjust along the bottom telescopic groove 12 by telescoping. When the internal telescopic cover 131 is completely retracted into the bottom telescopic groove 12, the switching gear 24 axially connected to the upper end of the movable drive guide blade 14 is meshed with the bottom drive gear 17 for transmission; when the internal telescopic cover 131 extends outwardly to the outside of the bottom telescopic groove 12, the switching gear 24 located away from the end of the movable drive guide blade 14 is meshed with the bottom drive gear 17 for transmission, and the switching gears on both sides of the upper transition groove 23 are connected by a horizontal synchronous shaft transmission.

[0047] In order to maintain the connection with the inner condensation flow channel 18 after switching, the first inner flow guide channel 19 and the second inner flow guide channel 20 are connected through the inner flow guide channel 25 on one side of the inner telescopic cover 131.

[0048] The lateral hydraulic control strut 132 controls the internal telescopic cover shell 131 to slide and adjust along the bottom telescopic groove 12 by telescoping. When the internal telescopic cover shell 131 is completely retracted into the bottom telescopic groove 12, the first internal guide channel 19 is connected with the inner condensation flow channel 18, and then the second internal guide channel 20 is blocked and closed by the bottom telescopic groove 12; when the internal telescopic cover shell 131 extends outward from the outside of the bottom telescopic groove 12, the second internal guide channel 20 is connected with the inner condensation flow channel 18, and the first internal guide channel 19 is closed by sliding the sliding closing cover plate 21 to reset.
