Description

Technical Field

[0001] This utility model relates to the field of energy recovery technology for high-frequency heating equipment, and in particular to an energy recovery device for high-frequency heating equipment. Background Technology

[0002] High-frequency heating, also known as induction heating, is a method of heating an electrical conductor (usually a metal) using electromagnetic induction. It generates eddy currents in the metal, causing Joule heating of the metal due to its resistance.

[0003] A search revealed a high-frequency heating device for heat treatment of iron bars, with publication number CN218041819U. The device includes a high-frequency heating chamber, an induction coil fixedly connected to the surface of the chamber, an iron bar placed inside the induction coil, a fixed sleeve slidably connected to the surface of the chamber, and the inner wall of the fixed sleeve slidably connected to the surface of the iron bar. An extrusion groove is formed on the surface of the fixed sleeve, and a clamping mechanism is provided inside the extrusion groove. This clamping mechanism allows the device to clamp and fix the iron bar during heating, ensuring that the center of the iron bar and the center of the induction coil are on the same vertical line. This minimizes the risk of the iron bar's surface contacting the inner wall of the induction coil, preventing short circuits. It also reduces the need for workers to use additional shims to place the iron bar, simplifying the device's operation.

[0004] When the device in the disclosed patent is in use, the induction coil itself generates Joule heat due to the resistance effect. The heat radiated by the workpiece and the high-temperature exhaust gas accumulated in the heating chamber are usually directly discharged into the surrounding air, which not only causes air pollution but also wastes heat and easily leads to excessively high ambient temperature, increasing the discomfort of workers. Utility Model Content

[0005] In response to the technical problems in existing patents, where the induction coil itself generates Joule heat due to the resistance effect during use, and the heat radiated by the workpiece and the high-temperature exhaust gas accumulated in the heating chamber are usually directly discharged into the surrounding air, causing not only air pollution and heat waste, but also easily leading to excessively high ambient temperatures and increasing worker discomfort, this utility model provides an energy recovery device for high-frequency heating equipment.

[0006] The technical solution adopted in this utility model is: an energy recovery device for a high-frequency heating equipment, comprising: A high-frequency heating device, wherein an induction coil is provided on one side of the high-frequency heating device; A heat recovery mechanism includes a protective cover on one side of the high-frequency heating equipment, an air intake head inside the protective cover, a water tank on one side of the high-frequency heating equipment, a connecting pipe connected to one side of the air intake head, an air pump connected to the upper part of the water tank, a hot water exchange tank inside the water tank, multiple exhaust pipes installed on the upper side of the hot water exchange tank, and an air outlet nozzle connected to the upper side of the exhaust pipes. One end of the connecting pipe extends out of the protective cover and connects to the water tank.

[0007] Furthermore, the high-frequency heating device has a support base located below the induction coil on one side, and a limiting groove is provided on the upper side of the support base.

[0008] Furthermore, the suction head has a circular shell structure, with multiple suction holes evenly distributed at the bottom end of the suction head, an air inlet at the bottom end of the protective cover, and a limiting insertion hole on the upper side of the protective cover.

[0009] Furthermore, the inner diameter of the suction head and the inner diameter of the limiting groove are smaller than the diameter of the inner wall of the induction coil spiral.

[0010] Furthermore, the upper part of the hot water tank is provided with a water outlet pipe that passes through the tank at one end, and a water pump is provided on one side of the tank. One end of the water pump extends into the tank and is connected to the lower part of the hot water tank.

[0011] Furthermore, the side of the water tank is connected to an inlet and outlet valve corresponding to the hot water exchange tank. The upper side of the hot water exchange tank is provided with a through hole corresponding to the exhaust pipe. The exhaust pipe is fixed in the through hole. One side of the protective cover is provided with a viewing hole. One side of the viewing hole is provided with a transparent plate. The upper side of the protective cover is provided with a limiting ring. Multiple guide grooves are arranged in a circular array inside the limiting ring. A limiting block slides in the guide groove. A spring damper is provided between the limiting block and the inner wall of the guide groove. The end of the limiting block near the axis of the limiting ring is curved, and the upper side of the end near the axis of the limiting ring is provided with a rounded corner.

[0012] The beneficial effects of this utility model are: By installing an exhaust pipe on the hot water exchange tank, when the exhaust gas passes through the exhaust pipe, the water pump drives cold water into the hot water exchange tank to come into contact with the outside of the exhaust pipe. The exhaust pipe absorbs the heat of the high-temperature exhaust gas, and the heat in the exhaust gas can be recovered by the flowing water in the hot water exchange tank, reducing the probability of heat waste. At the same time, it reduces the temperature of the exhaust gas after treatment and discharge into the air, reducing the impact on the surrounding air. By placing the exhaust nozzle inside the water tank, it is easy to draw the high-temperature exhaust gas inside the protective cover into the water tank, and then spray it into the water located above the water exchange tank through the exhaust pipe and exhaust nozzle, thereby removing solid particles and some harmful gases that can easily dissolve water from the exhaust gas. By setting limit rings and limit blocks, it is easy to squeeze the iron rod through multiple limit blocks, pass between multiple limit blocks, and then insert it into the limit slot on the support base through the limit insertion hole and induction coil. This facilitates the support base to support the iron rod, and the multiple limit blocks elastically position the iron rod through the spring damper, reducing the probability of the iron rod swinging horizontally.

One end of the connecting pipe 204 extends out of the protective cover 201 and connects to the water tank 203.

[0019] Furthermore, a support base 102 is provided on one side of the high-frequency heating device 1, located below the induction coil 101, and a limiting groove 103 is provided on the upper side of the support base 102.

[0020] Furthermore, the suction head 202 has a ring-shaped shell structure, and multiple suction holes are evenly distributed at the bottom end of the suction head 202. The bottom end of the protective cover 201 is provided with an air inlet 209, and the upper side of the protective cover 201 is provided with a limiting insertion hole 210.

[0021] Furthermore, the inner diameter of the suction head 202 and the inner diameter of the limiting groove 103 are smaller than the diameter of the spiral inner wall of the induction coil 101.

[0022] Furthermore, the upper part of the hot water tank 206 is provided with an outlet pipe 211 that passes through the water tank 203, and a water pump 212 is provided on one side of the water tank 203. One end of the water pump 212 extends into the water tank 203 and is connected to the lower part of the hot water tank 206.

[0023] Furthermore, the side of the water tank 203 is connected to an inlet / outlet valve 213 corresponding to the hot water exchange tank 206. The upper side of the hot water exchange tank 206 is provided with a through hole 214 corresponding to the exhaust pipe 207. The exhaust pipe 207 is fixed in the through hole 214. One side of the protective cover 201 is provided with a viewing hole, and one side of the viewing hole is provided with a transparent plate 215. The upper side of the protective cover 201 is provided with a limiting ring 216. Multiple guide grooves 217 are arranged in a circular array inside the limiting ring 216. A limiting block 218 slides in the guide groove 217. A spring damper 219 is provided between the limiting block 218 and the inner wall of the guide groove 217. The end of the limiting block 218 near the axis of the limiting ring 216 is curved, and the upper side of the end near the axis of the limiting ring 216 is provided with a rounded corner.

[0024] Working principle: The iron rod is pressed against multiple limiting blocks 218, passes between the limiting blocks 218, and then passes through the limiting insertion hole 210, through the induction coil 101, and is inserted into the limiting groove 103 on the support base 102. This facilitates the support base 102 to support the iron rod, and the multiple limiting blocks 218 elastically position the iron rod through the spring damper 219, reducing the probability of horizontal swing of the iron rod. The induction coil 101 heats the iron rod, and the air pump 205 is turned on, driving the air suction head 202 to draw the high-temperature exhaust gas in the protective cover 201 into the water tank 203. Then, the exhaust gas is sprayed into the water tank 203 through the exhaust pipe 207 and the air nozzle 208. The water located above the hot water exchange tank 206 removes solid particles and some harmful gases that can easily dissolve in the exhaust gas. When the exhaust gas passes through the exhaust pipe 207, the water pump 212 drives cold water into the hot water exchange tank 206 to contact the outside of the exhaust pipe 207. The exhaust pipe 207 absorbs the heat of the high-temperature exhaust gas, and then the water is discharged through the outlet pipe 211. This facilitates the recovery of heat from the exhaust gas through the flowing water in the hot water exchange tank 206, reducing the probability of heat waste. At the same time, it reduces the temperature of the exhaust gas discharged into the air after treatment, reducing the impact on the surrounding air. The air enters the protective cover 201 through the air inlet 209 to balance the air pressure.
