Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for blast furnace accessories, and in particular to a high-frequency quenching device. Background Technology

[0002] Currently, quenching is often required during the production of blast furnace parts. Quenching is a heat treatment process that involves heating to a suitable temperature and then rapidly cooling to obtain high strength, high hardness, high wear resistance, and good toughness.

[0003] Currently, high-frequency induction heating machines are a type of equipment that provides high-efficiency and rapid heating of metal materials. They utilize the principle of electromagnetic induction to directly generate eddy currents inside the metal, thereby achieving rapid and uniform heating, and are widely used today.

[0004] Existing high-frequency quenching devices are not convenient for stably clamping different blast furnace parts, nor are they convenient for automatically moving the blast furnace parts downward to pass through the induction coil, thus affecting work efficiency, and are not convenient for effectively treating the fumes generated during the heating process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-frequency quenching device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-frequency quenching device includes a cooling water tank, a support plate welded to one outer wall of the cooling water tank, a lifting clamping mechanism, and a fume purification mechanism. A high-frequency induction heater is fixedly installed on the top outer wall of the support plate, and an induction coil is provided on the high-frequency induction heater.

[0008] The lifting clamping mechanism includes a vertical frame welded to the side wall of the cooling water tank, a motor mounting plate welded to the top outer wall of the vertical frame, a servo motor fixedly installed on the side wall of the motor mounting plate, a slide groove opened on the vertical frame, a vertical lead screw rotatably installed in the slide groove, an adjusting rod threadedly connected to the vertical lead screw, a fixed frame fixedly connected to the outer wall of one end of the adjusting rod, and a pneumatic flexible clamping assembly provided on the fixed frame.

[0009] Preferably, the output shaft of the servo motor is coaxially and fixedly connected to the top end of the vertical lead screw via a coupling, and the outer wall of the adjusting rod is slidably connected to the inner wall of the slide groove.

[0010] Preferably, the pneumatic flexible clamping assembly includes a guide shaft welded to a fixed frame, two centering sliders slidably connected to the guide shaft, two flexible clamps symmetrically fixedly installed on the side walls of the two centering sliders, a cylinder fixedly installed on the top outer wall of the fixed frame, a slide rail opened on one side of the fixed frame, a T-shaped slider, and two linkage diagonal rods symmetrically hinged to the side walls of the T-shaped slider.

[0011] Preferably, the piston rod of the cylinder extends into the slide rail and is fixedly connected to the top of the T-shaped slider. The T-shaped slider is slidably connected to the inner wall of the slide rail, and the bottom ends of the two linkage inclined rods are respectively hinged to the tops of the two centering sliders.

[0012] Preferably, the smoke purification mechanism includes a purification box fixedly connected to the outer wall of the other side of the cooling water pool, a smoke hood, a smoke extraction fan fixedly installed at the bottom of the purification box, two filter element mounting frames inserted into the purification box in sequence, and a HEPA filter element and an activated carbon filter element fixedly connected in sequence within the two filter element mounting frames.

[0013] Preferably, the top of the purification chamber is connected to the smoke hood via a smoke extraction pipe, and the HEPA filter is located above the activated carbon filter.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Equipped with a lifting clamping mechanism, the pneumatic flexible clamping component facilitates the stable clamping of different blast furnace parts to meet the positioning requirements of different blast furnace parts. At the same time, the servo motor controls the rotation of the vertical screw, which enables the adjusting rod threadedly connected to the vertical screw to drive the clamped blast furnace parts to move downward automatically to pass through the induction coil to achieve the effect of automatic heating. This can effectively improve the working efficiency of the quenching process of blast furnace parts.

[0016] 2. Equipped with a smoke purification mechanism, the suction generated by the start-up of the exhaust fan draws the smoke produced during the heating process into the purification chamber through the smoke hood and exhaust pipe. After passing through layers of purification and filtration by HEPA and activated carbon filters, the smoke is discharged into the outside air environment. This facilitates the effective treatment of the smoke generated during the heating process, thereby reducing the pollution of the working environment caused by the smoke. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-4 A high-frequency quenching device includes a cooling water tank 1, the low-temperature coolant in the cooling water tank 1 being able to rapidly cool the heated metal material, a support plate 2 welded to one side of the outer wall of the cooling water tank 1, and a lifting clamping mechanism.

[0025] In this embodiment, a high-frequency induction heater 3 is fixedly installed on the top outer wall of the support plate 2. The high-frequency induction heater 3 is equipped with an induction coil 4. When the metal material is inside the induction coil 4, it can be fully heated. The lifting clamping mechanism includes:

[0026] Vertical frame 5 and motor mounting plate 6 are welded to the side wall of cooling water tank 1 and to the top outer wall of vertical frame 5.

[0027] The slide groove, servo motor 7, and vertical lead screw 8 are provided. The slide groove is opened on the vertical frame 5, and the vertical lead screw 8 is rotatably installed in the slide groove. The servo motor 7 is fixedly installed on the side wall of the motor mounting plate 6. The output shaft of the servo motor 7 is coaxially and fixedly connected to the top end of the vertical lead screw 8 through a coupling.

[0028] Adjusting rod 9 and fixing bracket 10 are provided. The adjusting rod 9 is threadedly connected to the vertical lead screw 8. The outer wall of the adjusting rod 9 is slidably connected to the inner wall of the slide groove. The fixing bracket 10 is fixedly connected to the outer wall of one end of the adjusting rod 9.

[0029] A pneumatic flexible clamping assembly is mounted on a fixed frame 10 and includes a guide shaft 11 welded to the fixed frame 10, two centering sliders 12 slidably connected to the guide shaft 11, two flexible clamps 13 symmetrically fixedly mounted on the side walls of the two centering sliders 12, a cylinder 14 fixedly mounted on the top outer wall of the fixed frame 10, a slide rail opened on one side of the fixed frame 10, a T-shaped slider 15, and two linkage diagonal rods 16 symmetrically hinged to the side walls of the T-shaped slider 15.

[0030] Furthermore, the piston rod of cylinder 14 extends into the slide and is fixedly connected to the top of T-shaped slider 15. T-shaped slider 15 is slidably connected to the inner wall of the slide. The bottom ends of the two linkage rods 16 are respectively hinged to the top of the two centering sliders 12.

[0031] In this embodiment, the piston rod of cylinder 14 retracts to move T-shaped slider 15 upward. Under the linkage effect of two linkage inclined rods 16, the two centering sliders 12 will drive the two flexible clamps 13 to center and move closer together to clamp the blast furnace parts that need to be quenched. This makes it easier to meet the positioning requirements of different blast furnace parts.

[0032] Secondly, the vertical lead screw 8 is rotated by the servo motor 7. Then, under the limit of the slide, the adjusting rod 9, which is threaded to the vertical lead screw 8, will drive the clamped blast furnace parts to move downwards automatically. During the downward movement, the blast furnace parts will pass through the induction coil 4 and be fully heated by it. After the heating is completed, the part will leave the induction coil 4 and be immersed in the cooling water pool 1 for rapid cooling. This can effectively improve the quenching efficiency.

[0033] Example 2, refer to Figure 1 , Figure 3 and Figure 5 This embodiment is an optimization based on embodiment 1, specifically: a high-frequency quenching device, which also includes a fume purification mechanism;

[0034] In this embodiment, the smoke purification mechanism includes a purification box 17 fixedly connected to the outer wall of the other side of the cooling water pool 1, a smoke hood 18, a smoke extraction fan 19 fixedly installed at the bottom of the purification box 17, two filter element mounting frames 20 inserted into the purification box 17 in sequence, and a HEPA filter element 21 and an activated carbon filter element 22 fixedly connected into the two filter element mounting frames 20 in sequence. The top of the purification box 17 is connected to the smoke hood 18 through a smoke extraction pipe, and the HEPA filter element 21 is located above the activated carbon filter element 22.

[0035] In this embodiment, the suction generated by the start-up of the exhaust fan 19 allows the smoke generated during the heating process to be drawn into the purification chamber 17 through the smoke hood 18 and the smoke pipe. After passing through layers of purification and filtration by the HEPA filter 21 and the activated carbon filter 22, the smoke is discharged into the outside air environment. This facilitates the effective treatment of the smoke generated during the heating process, thereby reducing the pollution of the working environment caused by the smoke.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
