[0002] Steel is a general term for iron-carbon alloys. With its low price and reliable performance, it has become one of the most used materials in the world and is widely used in the construction, manufacturing and daily life. In order to change the crystal structure and hardness of steel. After the steel is processed and formed, it needs to be quenched, which can transform the initial austenite phase into martensite or bainite phase, significantly improving the hardness of the steel. The traditional quenching mechanism needs to be set up independently and cannot be directly integrated on the conveying equipment. In addition, the high-temperature steam generated during the quenching process cannot be reused, and the waste of resources is very serious. In order to cooperate with the quenching, it is necessary to control the lifting of the steel, resulting in high energy consumption and equipment costs. Summary of the invention

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4 A sunken quenching device used for cooling bed transportation is shown, comprising a horizontal frame 1, a roller 2 for supporting transportation is installed inside the horizontal frame 1, an internal quenching pool 3 and an internal reflow pool 4 are fixedly installed at the unloading end of the roller 2 inside the horizontal frame 1, an internal elastic support roller group 5 is elastically assembled at the upper opening position inside the internal quenching pool 3, an internal transition support roller 6 matching the internal elastic support roller group 5 is installed at the upper opening position inside the internal reflow pool 4, a flip-type closed cover plate 7 is installed on the right side of the internal quenching pool 3 at the opening side, an overhead gas collecting hood 8 is installed on the top surface of the internal quenching pool 3, and a bottom-mounted electrically controlled air and liquid suction pump 9 is installed on the bottom surface of the internal reflow pool 4.
[0029] Working principle: the steel is translated along with the roller 2, and then when it moves to the internal elastic support roller group 5, the internal elastic support roller group 5 will move down due to the gravity of the steel and drop into the quenching liquid in the internal quenching pool 3 to perform the quenching operation. The high temperature generated during quenching will vaporize the quenching liquid, and then the top-mounted gas collecting hood 8 will be used to draw water vapor back into the internal quenching pool 3, and then the flip-type closed cover 7 will be flipped, and then the quenching liquid in the internal quenching pool 3 will flow into the internal reflux pool 4. At this time, the height of the internal elastic support roller group 5 is slightly higher than the internal transition support roller 6, and the steel can slide onto the internal transition support roller 6. When the steel completely slides onto the internal transition support roller 6, the flip-type closed cover 7 flips upward and resets, and then refluxes the internal reflux pool 4 to the internal quenching pool 3 to raise the water level.
[0030] In order to ensure the lifting stability and guidance of the internal elastic support roller set 5 , three lateral lifting guide rails 10 for supporting the internal elastic support roller set 5 are installed on the inner walls on both sides of the internal quenching pool 3 .
[0031] In order to cooperate with the sliding lifting adjustment, the internal elastic support roller group 5 includes a lateral sliding block 51 slidably inserted into the inside of the lateral lifting guide rail 10, a horizontal assembly tube 52 fixed on the side wall of the lateral sliding block 51, an external support sleeve 53 movably sleeved on the outside of the horizontal assembly tube 52 and a bottom return spring 54 elastically assembled at the bottom of the lateral sliding block 51.
[0032] The heights of the lateral sliding block 51, the transverse assembly tube 52, and the external support sleeve 53 are adjusted by the weight of the steel material itself.
[0033] In order to cooperate with the lateral transition, a lateral drainage transition groove is opened on the right side of the internal quenching pool 3 at the installation end of the flip-type closed cover 7. The flip-type closed cover 7 includes a flip-type closed cover 71 movably installed inside the lateral drainage transition groove and an electrically controlled support rod 72 movably installed on the inner wall of the internal quenching pool 3.
[0034] The electric control support rod 72 controls the flipping and adjustment of the flip closing cover plate 71 by extending and retracting.
[0035] In order to cooperate with the lifting and lowering adjustment, an outer electric-controlled lifting support rod 11 for controlling the lifting and lowering of the top-mounted gas collecting hood 8 is bolted to the upper end of the outer side surface of the internal quenching pool 3.
[0036] The telescopic end of the outer electrically controlled lifting support rod 11 is fixedly assembled with the outer side surface of the top-mounted air collecting hood 8 .
[0037] In order to cooperate with the bottom diversion, an embedded bottom guide trough 12 for installing a bottom-mounted electric-controlled air and liquid pump 9 is opened on the bottom surface of the internal reflux pool 4, and an annular guide cover 13 is installed at the upper opening of the embedded bottom guide trough 12.
[0038] In order to cooperate with the lateral flow guidance, external material guide pipes 14 are fixedly mounted on the outer sides of the internal quenching tank 3 and the internal reflux tank 4 .
[0039] The embedded bottom material guide trough 12 and the overhead gas collecting hood 8 are connected by a lateral air guide pipe. When the steel is introduced into the internal quenching pool 3 for quenching, the bottom-mounted electrically controlled air and liquid suction pump 9 rotates rapidly to draw water vapor in through the air inlet at the bottom of the embedded bottom material guide trough 12, and then introduces it into the internal quenching pool 3 through the external material guide pipe 14 for condensation recovery; when the quenching liquid flows into the internal reflux pool 4, the bottom-mounted electrically controlled air and liquid suction pump 9 rotates rapidly to introduce it into the internal quenching pool 3 through the external material guide pipe 14 for reflux.
[0040] In order to cooperate with automatic opening and closing, a lateral return hole is opened at the bottom of the inner side of the lateral lifting guide rail 10.
[0041] A bottom reflux hole is also installed at a lower position on the inner side of the internal quenching pool 3, and a one-way check valve is installed at the connecting end between the bottom reflux hole and the bottom material guide groove 12 to facilitate liquid and air discharge through the bottom reflux hole when the lateral reflux hole is closed.
[0042] In order to cooperate with the automatic flipping adjustment, a pressure sensing switch 15 is installed on the side wall of the flip closing cover 71.
[0043] When the steel moves to the right, the right end of the steel will squeeze the pressure sensing switch 15. At this time, the pressure sensing switch 15 will be squeezed, and then the electric control support rod 72 will be controlled to contract, and then the electric control support rod 72 will drive the flip closing cover 71 to flip. At this time, the lateral drainage transition groove is opened, and then the steel slides and translates to the right and moves to the internal transition support roller 6. At the same time, the quenching liquid in the internal quenching pool 3 is poured into the internal reflux pool 4, and then after the flip closing cover 71 is flipped upward and reset, the liquid in the internal reflux pool 4 is pumped back into the internal quenching pool 3 through the bottom-type electric control vacuum pump 9.
[0044] In order to facilitate the reflux, the bottom surface of the internal reflux pool 4 gradually decreases in height from the edge to the center.
[0045] The advantage is that the edge position can be directed toward the center, so that the air at the bottom of the overhead air collecting hood 8 can be sucked in through the high-speed rotation of the bottom-mounted electric vacuum pump 9, and then introduced into the internal quenching pool 3 through the external material guide pipe 14 for condensation reflux operation; when the flip-type closed cover 7 is flipped to the right, the quenching liquid at the upper end of the internal quenching pool 3 is introduced into the internal reflux pool 4, and then quickly pumped into the internal quenching pool 3.
[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
