Description

Technical Field

[0001] This utility model belongs to the technical field of metal heat treatment equipment, specifically relating to a heat treatment device for processing impact crusher liner plates. Background Technology

[0002] Heat treatment is a metal heat treatment process that involves heating, holding, and cooling metallic materials in a certain medium to change their properties by altering the crystal structure on the surface or inside of the material.

[0003] When using a traditional box-type resistance furnace to process lining plates, the heating of the lining plates is slow, resulting in high energy consumption. It is also difficult to control the heating temperature to maintain stability, and the temperature uniformity is poor, leading to large fluctuations in the hardness of the lining plates.

[0004] The quenching state cannot be well adjusted during the quenching of the liner, making it difficult to ensure that the liner has good performance; at the same time, the existing fixed clamping results in a small processing capacity per batch, and the liner is heated unevenly, making it inconvenient to use when heat treating the liner. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a heat treatment device for processing impact crusher liners. This heat treatment device can fully heat all parts of the liner through an electromagnetic induction heating mechanism, which can effectively improve the heating rate. The atomizing quenching mechanism can be adjusted to a suitable quenching state according to the condition of the liner, and can uniformly quench all parts of the liner, ensuring that the liner has good performance. This can effectively improve the processing efficiency and quality of the liner and make it easier to use when heat treating the liner.

[0006] A heat treatment device for processing impact crusher liners includes a processing barrel and a treatment barrel. The processing barrel is equipped with an electromagnetic induction heating mechanism for heating the liners inside and a temperature sensor for measuring the internal temperature is fixedly installed on its outer surface. The treatment barrel is fixedly connected to the bottom of the processing barrel and is equipped with an atomizing quenching mechanism for quenching the liners inside. A lifting cylinder is fixedly installed on the lower surface of the treatment barrel, and the movable rod of the lifting cylinder passes through the interior of the processing barrel and the processing barrel. The top of the movable rod of the lifting cylinder is fixedly connected to a base, and the top of the base is equipped with a liner rotating mechanism that can clamp and fix multiple liners and drive them to rotate. A drive mechanism that can drive the liner rotating mechanism is provided at the center of the lower surface of the treatment barrel.

[0007] Preferably, the electromagnetic induction heating mechanism includes an upper spiral induction coil and a lower spiral induction coil, the upper spiral induction coil and the lower spiral induction coil are interconnected and the spiral spacing of the upper spiral induction coil is greater than the spiral spacing of the lower spiral induction coil, and a heat insulation plate is fixedly connected to the inner wall of the processing barrel, and both the upper spiral induction coil and the lower spiral induction coil are fixedly connected to the inner wall of the heat insulation plate.

[0008] Preferably, the atomizing quenching mechanism includes an annular tube, atomizing nozzles, and a connecting pipe. Multiple atomizing nozzles are fixedly installed in a ring array on the inner ring of the annular tube, and each of the multiple atomizing nozzles has an upward tilt angle of °. There are two annular tubes, which are vertically aligned and connected to each other through the connecting pipe. Both annular tubes are fixedly connected to the inner wall of the processing tank, and the inlet of the connecting pipe can be connected to an external pipe.

[0009] Preferably, the number of temperature sensors is several, and the several temperature sensors are all vertically and equidistantly fixed on the outer surface of the processing barrel. The detection ends of the several temperature sensors are all inserted inside the processing barrel and correspond to the gap between the upper and lower spiral induction coils.

[0010] Preferably, the liner rotation mechanism includes a rotating plate, an internal gear ring, a four-jaw chuck, a driven gear, and a driving gear. The top of the base is embedded in the lower surface of the rotating plate, and the rotating plate can rotate relative to the base. The internal gear ring is fixedly connected to the lower surface of the rotating plate and rotatably connected inside the base. There are several four-jaw chucks, and a rotating shaft is fixedly connected to the center of the lower surface of each four-jaw chuck. The shafts are rotatably connected to the upper surface of the rotating plate through bearings. A driven gear is fixedly connected to the bottom end of the rotating shaft on the lower surface of each four-jaw chuck. Several driven gears are rotatably connected inside the base, and the driving gear meshes with several driven gears and is rotatably connected to the center of the base.

[0011] Preferably, the drive mechanism includes a drive motor, a worm gear, a worm wheel, and a rotating insert.

The top end of the rotating insert passes through the lower surface of the base and is fixedly connected to the center of the lower surface of the drive gear.

[0012] The beneficial effects of the above technical solution are as follows:

[0013] This heat treatment device for processing impact crusher liners, through the arrangement of an electromagnetic induction heating mechanism, an atomizing quenching mechanism, and a liner rotation mechanism, allows the drive mechanism to simultaneously rotate the liner on the liner rotation mechanism and revolve around a central point. This ensures that all points on the liner surface periodically enter a high-intensity magnetic field zone, achieving three-dimensional uniform heating, thereby eliminating temperature gradients, effectively reducing temperature differences, and ensuring a constant heating temperature. This allows the electromagnetic induction heating mechanism to fully heat all parts of the liner. The lifting cylinder drives the liner rotation mechanism from top to bottom within the electromagnetic induction heating mechanism, enabling the electromagnetic induction heating mechanism to heat the liner... The plate undergoes segmented induction heating. First, the liner plate is preheated to reduce the risk of thermal stress cracking, and then the liner plate is rapidly austenitized, which can effectively improve the heating rate. The atomizing quenching mechanism can be adjusted to a suitable quenching state according to the condition of the liner plate, and can quench all parts of the liner plate evenly, ensuring that the liner plate has good performance. The liner plate rotation mechanism can fix multiple liner plates at the same time, and can heat treat multiple liner plates simultaneously, ensuring that multiple liner plates are heated evenly, which can effectively improve the processing efficiency and quality of the liner plates, and is more convenient to use when heat treating the liner plates.

[0022] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 7 The embodiments are described in detail below.

[0023] This embodiment provides a heat treatment device for processing impact crusher liners, as shown in the attached figure. Figure 1-7 As shown, the device includes a processing barrel 1 and a treatment barrel 2. A sealing cap can be installed on the top of the processing barrel 1 to seal it. The interior of the processing barrel 1 is equipped with an electromagnetic induction heating mechanism for heating the liner. The electromagnetic induction heating mechanism includes an upper spiral induction coil 5 and a lower spiral induction coil 6, which are interconnected. The spiral spacing of the upper spiral induction coil 5 is greater than that of the lower spiral induction coil 6. Based on Faraday's law, an alternating magnetic field is generated inside the upper spiral induction coil 5 and the lower spiral induction coil 6 when energized. This induces eddy currents on the surface of the liner inside the coil, thereby heating the liner. The area inside the upper spiral induction coil 5 is a preheating zone, and its power density is lower than that of the lower spiral induction coil 6. The area inside the lower spiral induction coil 6 is an austenitizing zone. When the liner is inside the lower spiral induction coil 6, the liner structure can be austenitized. The inner wall of the processing barrel 1 is fixedly connected to a heat insulation plate 7, and both the upper spiral induction coil 5 and the lower spiral induction coil 6 are fixedly connected to the inner wall of the heat insulation plate 7. The heat insulation plate 7 can be made of aluminum silicate, which can effectively reduce heat radiation loss and reduce energy consumption.

[0024] A number of temperature sensors 11 are fixedly installed on the outer surface of the processing barrel 1 to measure the temperature inside. The temperature sensors 11 are vertically and equidistantly fixed on the outer surface of the processing barrel 1. The detection ends of the temperature sensors 11 are inserted into the interior of the processing barrel 1 and correspond to the gap between the upper spiral induction coil 5 and the lower spiral induction coil 6. This allows for real-time monitoring of the temperature inside the processing barrel 1, thereby accurately adjusting the power of the electromagnetic induction heating mechanism according to the different materials of the liner. Furthermore, the upper spiral induction coil 5 and the lower spiral induction coil 6 can be covered with ceramic fiber sleeves, which have a temperature resistance of >1300℃, ensuring their stability.

[0025] The processing tank 2 is fixedly connected to the bottom of the processing tank 1 and is equipped with an atomizing quenching mechanism inside for quenching the liner. The lower surface of the processing tank 2 is fixedly connected to a support leg for support. The atomizing quenching mechanism includes an annular tube 8, atomizing nozzles 9, and a connecting pipe 10. Multiple atomizing nozzles 9 are fixedly installed in a ring array on the inner ring of the annular tube 8, and each of the multiple atomizing nozzles 9 has a 15° upward tilt angle to avoid splashing of the medium vertically towards the liner. There are two annular tubes 8, which are vertically aligned and connected to each other through the connecting pipe 10. Both annular tubes 8 are fixedly connected to the inner wall of the processing tank 2, and the inlet of the connecting pipe 10 can be connected to an external pipe. Different media can be injected into the annular tubes 8 through the external pipe. For example, compressed air can be injected to pre-cool the high-temperature liner to prevent deformation caused by direct quenching; a mixture of deionized water and nano suspension can also be injected to quench the liner and ensure the uniformity of quenching through multiple circumferential atomizing nozzles 9.

[0026] A lifting cylinder 3 is fixedly installed on the lower surface of the processing barrel 2, and the movable rod of the lifting cylinder 3 passes through the interior of the processing barrel 2 and the processing barrel 1. The top of the movable rod of the lifting cylinder 3 is fixedly connected to a base 4, and the top of the base 4 is provided with a liner rotating mechanism that can clamp and fix multiple liners and drive them to rotate. The lifting cylinder 3 can drive the base 4 and the upper liner rotating mechanism to move up and down at a uniform speed, thereby driving multiple liners to move within the processing barrel 1 and the processing barrel 2, facilitating different processing steps. The liner rotating mechanism includes a rotating plate 12, an internal gear ring 13, a four-jaw chuck 14, a driven gear 15, and a driving gear 16. The top of the base 4 is embedded in the lower surface of the rotating plate 12, and the rotating plate 12 can rotate relative to the base 4. The internal gear ring 13 is fixedly connected to the lower surface of the rotating plate 12 and rotatably connected to the interior of the base 4. There are several four-jaw chucks 14, and each of the lower surfaces of the four-jaw chucks 14 is fixedly connected to a rotating shaft, which is rotatably connected to the base 1 via the rotating shaft and bearing. The upper surface of the rotating plate 12 and the four-jaw chuck 14 are existing known technologies, so they will not be described in detail here. Multiple liner plates can be vertically fixed in multiple four-jaw chucks 14, and the bottom end of the rotating shaft on the lower surface of each four-jaw chuck 14 is fixedly connected to a driven gear 15. Several driven gears 15 are rotatably connected to the inside of the base 4, and the driving gear 16 meshes between several driven gears 15 and is rotatably connected to the center of the inside of the base 4. The rotation of the driving gear 16 can drive the external multiple driven gears 15 to rotate, thereby causing the four-jaw chuck 14 to drive the liner plate fixed above it to rotate. At the same time, when the multiple driven gears 15 rotate, they can drive the external internal gear ring 13 to rotate, thereby causing the rotating plate 12 to rotate at a uniform speed, which can drive the four-jaw chuck 14 and the liner plate above to revolve around the axis of the rotating plate 12. Therefore, all parts of the liner plate can periodically enter the high-intensity magnetic field area to achieve three-dimensional uniform heating, thereby eliminating the temperature gradient and enabling the electromagnetic induction heating mechanism to fully heat all parts of the liner plate.

[0027] A drive mechanism is provided at the center of the lower surface of the processing barrel 2, which can drive the liner rotation mechanism. The drive mechanism includes a drive motor 17, a worm gear 18, a worm wheel 19, and a rotating rod 20. A protective shell 21 is fixedly connected to the center of the lower surface of the processing barrel 2, which supports and fixes the drive mechanism. The drive motor 17 is fixedly installed on the side of the protective shell 21, and its output end is connected to the worm gear 18 via a spline. The worm wheel 19 is rotatably connected inside the protective shell 21 and rotatably connected to the center of the lower surface of the processing barrel 2. The rotating rod 20 is vertically inserted through the axis of the worm wheel 19 and through the axis of the processing barrel 2 and the processing barrel 1. The top end of the rotating rod 20 passes through the lower surface of the base 4 and is fixedly connected to the center of the lower surface of the drive gear 16. The drive motor 17 drives the worm gear 18 to rotate, which in turn drives the worm wheel 19 to rotate. The rotating rod 20 can only slide up and down within the worm wheel 19 and cannot rotate. Therefore, when the worm wheel 19 rotates, it can drive the rotating rod 20 to rotate synchronously, thereby driving the drive gear 16 at its top to rotate. This enables the entire liner rotating mechanism to rotate, thereby driving the liner to rotate on its own axis and revolve around the sun. At the same time, the rotating rod 20 can rise and fall with the base 4, ensuring that the drive motor 17 is always below the processing tank 2 and can still drive the liner rotating mechanism to rotate during the lifting and lowering process. This separates the liner rotating mechanism and the drive motor 17 into two independent structures, preventing the drive motor 17 from rising and falling with the liner rotating mechanism and effectively avoiding damage when the drive motor 17 moves into the electromagnetic induction heating mechanism.

[0028] The lifting cylinder 3 is connected to the external air circuit through a pipe. The upper spiral induction coil 5, the lower spiral induction coil 6, the temperature sensor 11 and the drive motor 17 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0029] In summary, the operating steps of the heat treatment device for processing impact crusher liners are as follows:

[0030] 1. The liner plate rotation mechanism is lifted to the top of the processing barrel 1 by the lifting cylinder 3, and then multiple liners to be processed are vertically fixed in multiple four-jaw chucks 14, ensuring that each liner plate does not affect the others when it rotates.

[0031] 2. Then, the upper spiral induction coil 5 and the lower spiral induction coil 6 are energized. At the same time, the rotating plate 12 and the four-jaw chuck 14 are rotated by the drive mechanism, which drives the liner plate to rotate and revolve. The upper spiral induction coil 5 preheats the liner plate first. Then, the moving end of the lifting cylinder 3 is controlled to descend slowly and uniformly, so that the liner plate moves to the lower spiral induction coil 6. The lower spiral induction coil 6 can heat the liner plate at high temperature, thereby making the liner plate structure austenitized. The rotation and revolution of the liner plate can ensure that all parts of the plate are fully heated.

[0032] 3. After the liner plate has been fully heated, the lifting cylinder 3 drives the liner plate into the processing barrel 2. At this time, the liner plate continues to rotate and the quenching medium is injected into the annular pipe 8 through the external pipe and sprayed onto the surface of the liner plate from the atomizing nozzles 9 around the perimeter to fully quench the liner plate. The rotating liner plate can ensure the uniformity of its own quenching. After the quenching is completed, compressed air is blown out through the atomizing nozzles 9 to cool the liner plate, thereby completing the heat treatment process of the liner plate.

[0033] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
