Description

Technical Field

[0001] This application relates to the field of metal heat treatment technology, and in particular to an environmentally friendly heat treatment device. Background Technology

[0002] Currently, metal heat treatment is a process that alters the internal structure of metals by heating and cooling them, thereby improving their mechanical, physical, and chemical properties. Common heat treatment methods include quenching, normalizing, and tempering. These methods can be performed individually or in combination. Quenching involves heating the metal to a suitable temperature and then rapidly cooling it to increase its hardness and strength. Tempering, on the other hand, involves heating the metal to a temperature below its critical point after quenching, holding it at that temperature, and then cooling it to reduce the internal stress generated during quenching, decrease hardness, and increase toughness. Heat treatment is widely used in the processing and production of various metal parts.

[0003] Related technology can be found in Chinese patent application CN117512286B, which discloses a metal surface heat treatment device, including an equipment frame, a cooling pool, and a high-frequency quenching mechanism. The device includes: a frame support component: a rotating shaft is rotatably connected to the equipment frame, and clamping components for fixing metal rings are provided on the support; a station switching component: a guide and a transmission component are provided on the outer side of the equipment frame. When the sliding sleeve slides towards the disc-shaped frame, the guide first drives the rotating shaft to rotate 90 degrees, and then the transmission component drives the sliding arm to slide and extend along the support arm. Firstly, the disc-shaped frame drives the four support arms to switch stations by rotation, enabling simultaneous heat treatment, cooling, and drying of different groups of metal rings, thereby improving the efficiency of heat treatment of the metal rings. Secondly, as the trapezoidal block slides back to its original position, the arc-shaped clamping plate will radially retract inward, releasing the clamping state of the processed metal rings, thus facilitating the rapid replacement of processed metal rings by the operator.

[0004] Regarding the aforementioned technologies, during metal quenching, the cooling tank typically contains quenching oil. As the cooling tank comes into contact with air, a large amount of water mist is generated during cooling. This water mist contains quenching oil, and the mixture of water mist and quenching oil released into the air causes air pollution and harms the health of workers. Therefore, there is an urgent need for a heat treatment device to improve the air quality around the metal during heat treatment. Summary of the Invention

[0005] In order to improve the air quality around the heat treatment equipment, this application provides an environmentally friendly heat treatment equipment.

[0006] This application provides an environmentally friendly heat treatment device, which adopts the following technical solution: An environmentally friendly heat treatment device includes a heating chamber and a water-cooling pool. The heating chamber contains heating elements for heating metal. A guide pipe is connected to the side of the heating chamber near the water-cooling pool. The guide pipe is inclined from top to bottom along the direction from the heating chamber to the water-cooling pool. A cover plate is detachably connected to the upper end of the water-cooling pool. An air extraction element for evacuating the water-cooling pool is provided at the upper end of the cover plate. A conveying device is provided inside the water-cooling pool. The side of the conveying device near the heating chamber is located below the guide pipe. A box body is located on the side of the water-cooling pool away from the heating chamber. The side of the conveying device away from the heating chamber is located inside the box body. A shot blasting assembly is provided inside the box body to clean the oxide layer on the metal surface. A collection basket is provided on the lower end of the box body away from the water-cooling pool.

[0007] By adopting the above technical solution, when heat treating metal, the heating element heats the metal inside the heating chamber. The heated metal then passes through a guide pipe into a water-cooling pool for cooling. A cover plate seals the upper end of the water-cooling pool. During the metal cooling process, a large amount of water vapor is generated, which contains quenching oil. The extraction element extracts the water vapor and quenching oil from the water-cooling pool, which helps reduce the probability of polluting the surrounding environment. The conveying device transports the cooled metal into the chamber, and the shot blasting assembly cleans the oxide layer on the metal surface. The cleaned metal is then transported to a collection basket for recycling, thus improving the environmental quality around the heat treatment equipment.

[0008] Optionally, a first support block is fixed vertically inside the water-cooled pool. The first support block is located between the guide pipe and the conveying device. A second support block is slidably connected vertically to the upper end of the first support block. Several springs are provided between the first and second support blocks. In the natural state, the springs push the second support block to move away from the first support block. Support plates are fixed on both sides of the upper end of the second support block along the width direction of the water-cooled pool. The support plates are arranged along the length direction of the water-cooled pool. The support plates are inclined from top to bottom along the direction from the heating box to the water-cooled pool. The support plates are located below the guide pipe and above the conveying device. Several rollers are rotatably connected between the two support plates. The rollers are arranged along the length direction of the support plates.

[0009] By adopting the above technical solution, the first support block guides the movement of the second support block. When the metal separates from the guide tube, the metal comes into contact with the roller. The two support plates cooperate to support multiple rollers. Since the metal itself has weight, the second support block moves downward under the weight of the metal and squeezes the spring. The metal slides on the surface of the roller and eventually falls onto the conveying device. This helps to reduce the impact of the metal on the conveying device and improves the stability of metal conveying.

[0010] Optionally, the exhaust system includes a fan, an exhaust pipe, a heater, a connecting pipe, a cooler, and a scraper. The exhaust pipe is connected to the cover plate and located directly above the second support block. The fan is fixedly connected inside the exhaust pipe, the heater is fixedly connected to the outside of the exhaust pipe, the connecting pipe is connected to the side of the exhaust pipe away from the cover plate and is arranged vertically. The connecting pipe is located on one side of the water cooling pool along the width direction, the cooler is fixedly connected to the outside of the connecting pipe, and the scraper is located inside the connecting pipe. The scraper is used to remove the quenching oil inside the connecting pipe, and an oil box is detachably connected to the lower end of the connecting pipe.

[0011] By adopting the above technical solution, the blower draws the steam generated inside the water-cooled pool into the extraction pipe, and the heater heats the extraction pipe, which helps to reduce the probability of steam condensing and adhering to the inside of the extraction pipe. The steam enters the connecting pipe, and the cooler cools the steam, causing the quenching oil to adhere to the inner wall of the connecting pipe. The scraper scrapes the quenching oil on the inner wall of the connecting pipe into the oil box for recycling and removal, thereby improving the cleanliness of the environment around the water-cooled pool.

[0012] Optionally, the scraping component includes a rotating rod, a scraping ring, a handle, and a barrier membrane. The connecting pipe has a vertically opening for movement. The scraping ring is located inside the connecting pipe and is slidably connected to the connecting pipe vertically. The rotating rod is vertically positioned and located inside the moving opening. The rotating rod and the moving opening are interference-fitted. The upper end of the rotating rod is hinged to the scraping ring. The handle is fixedly connected to the side of the rotating rod away from the connecting pipe. The barrier membrane is detachably connected to the side of the rotating rod away from the handle and is adapted to the rotating rod.

[0013] By adopting the above technical solution, when the connecting pipe needs to be cleaned, the worker can turn the rotating rod out of the moving port by using the handle. The worker can then separate the barrier membrane from the rotating rod, thereby removing the quenching oil on the rotating rod. The rotating rod drives the scraper ring to move downwards, which in turn scrapes the quenching oil in the connecting pipe into the oil box, thus improving the convenience of quenching oil removal.

[0014] Optionally, the conveying device includes a conveyor belt and several baffles. The conveyor belt is located in the water-cooling pool and is arranged along the length of the water-cooling pool. Several baffles are fixedly connected to the surface of the conveyor belt and are arranged along the conveying direction of the conveyor belt. The baffles are arranged along the width of the conveyor belt. The side of the conveyor belt near the heating box is located below the roller, and the side of the conveyor belt away from the heating box passes through the box and is located above the collection basket.

[0015] By adopting the above technical solution, the cooled metal is conveyed on the surface of the conveyor belt, and the baffle blocks the metal, which helps to reduce the probability of the metal sliding down and improves the stability of metal conveying.

[0016] Optionally, the shot blasting assembly includes two storage bins, two conveying pipes, several ejectors, two air sources, and two air blowing pipes. The two storage bins are fixedly connected to the upper end of the housing on both sides along the width direction. The ejectors are located inside the housing and fixedly connected to both sides along the width direction of the housing, with the ejectors positioned above the conveyor belt. The conveying pipes correspond one-to-one with the storage bins. The two conveying pipes are located on both sides along the width direction of the housing, with the upper end of the conveying pipe connected to the storage bin and the lower end connected to the ejectors. The two air sources are fixedly connected to both sides along the width direction of the housing, with the air blowing pipes corresponding one-to-one with the air sources. The air blowing pipes are connected to the side of the two air sources that are close to each other and are located below the ejectors. Recovery components are provided on both sides along the width direction of the housing for recovering the shot inside the housing.

[0017] By adopting the above technical solution, the storage bin transports the shot to the ejector through the conveying pipe. The ejector sprays the shot onto the metal surface to remove the oxide layer on the metal surface. The air source and the air blowing pipe work together to blow the shot on the metal and conveyor belt surface to the bottom of the box. The recycling unit recycles and reuses the shot in the box, which improves the convenience of cleaning the oxide layer on the metal surface.

[0018] Optionally, the recycling component includes a collection bin, a first guide plate, a conveyor belt, and several collection boxes. A guide block is fixedly installed at the lower end of the bin along its length. The guide block is inclined from top to bottom along the direction from its center to both sides along its width. The collection bin is located at the lower end of the bin and directly below the storage bin. A discharge port is opened on both sides of the lower end of the bin along its width, and the discharge port is directly opposite the collection bin. Two second guide plates are fixedly installed on both sides of the lower end of the bin along its width. The discharge port is located between the two second guide plates. The second guide plates are inclined from top to bottom along the direction from the side of the two second guide plates that are far apart to the side of the two second guide plates that are close together. The conveyor belt is vertically arranged. The lower end of the conveyor belt is located inside the collection bin, and the upper end of the conveyor belt passes through the storage bin and is located inside the storage bin. Several collection boxes are fixedly connected to the surface of the conveyor belt. The first guide plate is fixedly connected to the inside of the storage bin. The first guide plate is inclined from top to bottom along the direction from the conveyor belt to the conveyor pipe.

[0019] By adopting the above technical solution, the guide block and the second guide plate work together to make the projectile fall through the discharge port into the collection bin. The conveyor belt moves the collection box and collects the projectile in the collection bin. When the collection box containing the projectile moves above the conveyor belt, the collection box tilts the projectile, and the projectile rolls along the first guide plate to the conveying pipe, which improves the convenience of projectile recycling.

[0020] Optionally, a cooling tower is provided on one side of the water-cooled pool along its width. The lower end of the water-cooled pool is connected to an inlet pipe and an outlet pipe, and the ends of the inlet pipe and the outlet pipe away from the water-cooled pool are both connected to the cooling tower.

[0021] By adopting the above technical solution, the cooling tower draws water from the water-cooled pool into the cooling tower through the outlet pipe for cooling and temperature reduction, and then transports the water to the inside of the water-cooled pool through the inlet pipe, thereby improving the convenience of water temperature regulation in the water-cooled pool.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When heat treating metal, the heating element heats the metal inside the heating chamber. The heated metal then passes through a guide pipe into a water-cooling pool for cooling. A cover plate seals the upper end of the water-cooling pool. During the metal cooling process, a large amount of water vapor is generated, which contains quenching oil. The extraction element extracts the water vapor and quenching oil from the water-cooling pool, which helps reduce the probability of polluting the surrounding environment. The conveying device transports the cooled metal into the chamber, and the shot blasting assembly cleans the oxide layer on the metal surface. The cleaned metal is then transported to a collection basket for recycling, improving the quality of the environment around the heat treatment equipment. 2. The blower draws the steam generated inside the water-cooled pool into the extraction pipe. The heater heats the extraction pipe, which helps reduce the probability of steam condensing and adhering to the inside of the extraction pipe. The steam enters the connecting pipe, and the cooler cools the steam, causing the quenching oil to adhere to the inner wall of the connecting pipe. The operator turns the rotating rod out of the moving port by the handle, and the operator separates the barrier membrane from the rotating rod, thereby removing the quenching oil on the rotating rod. The rotating rod drives the scraper ring to move downward, thereby scraping the quenching oil in the connecting pipe into the oil box, which improves the convenience of quenching oil removal. 3. The guide block and the second guide plate work together to allow the projectile to pass through the discharge port and fall into the collection bin. The conveyor belt moves the collection box and collects the projectile in the collection bin. When the collection box containing the projectile moves above the conveyor belt, the collection box tilts the projectile, and the projectile rolls along the first guide plate to the conveying pipe, which improves the convenience of projectile recycling.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses an environmentally friendly heat treatment device. Example

[0031] Reference Figure 1 An environmentally friendly heat treatment device includes a heating chamber 1 and a water-cooling pool 2. The heating chamber 1 is equipped with a heating element 11, which heats and transports metal. A guide pipe 12 is connected to the side of the heating chamber 1 near the water-cooling pool 2. The guide pipe 12 is inclined from top to bottom along the direction from the heating chamber 1 to the water-cooling pool 2. The heated metal passes through the guide pipe 12 and enters the water-cooling pool 2 for cooling.

[0032] Reference Figure 1 A cooling tower 27 is provided on one side of the water-cooled pool 2 along its width. The lower end of the water-cooled pool 2 is connected to an inlet pipe 28 and an outlet pipe 29. The ends of the inlet pipe 28 and the outlet pipe 29 away from the water-cooled pool 2 are both connected to the cooling tower 27. The cooling tower 27 draws water from the water-cooled pool 2 into the cooling tower 27 through the outlet pipe 29 for cooling and temperature reduction, and then transports the water to the interior of the water-cooled pool 2 through the inlet pipe 28, which improves the convenience of water temperature regulation in the water-cooled pool 2.

[0033] Reference Figure 1 The upper end of the water-cooled pool 2 is detachably connected to a cover plate 21. During the metal cooling process, a large amount of water vapor is generated, which contains quenching oil. If it is directly discharged into the air, it will cause air pollution. The cover plate 21 blocks the steam inside the water-cooled pool 2. The upper end of the cover plate 21 is equipped with an exhaust component 3, which extracts the steam from the water-cooled pool 2.

[0034] Reference Figure 2 and Figure 3 The extraction component 3 includes a fan 31, an extraction pipe 32, a heater 33, a connecting pipe 34, a cooler 35, and a scraper 36. The extraction pipe 32 is connected to the cover plate 21 and is located on the side of the water-cooled pool 2 near the heating box 1. The fan 31 is fixedly connected inside the extraction pipe 32, and the fan 31 draws the steam generated inside the water-cooled pool 2 into the extraction pipe 32. The heater 33 is fixedly connected to the outside of the extraction pipe 32, and the heater 33 heats the extraction pipe 32, which helps to reduce the probability of steam condensing and adhering to the inside of the extraction pipe 32. The connecting pipe 34 is connected to the side of the exhaust pipe 32 away from the cover plate 21 and is arranged vertically. The connecting pipe 34 is one side of the water cooling pool 2 along the width direction. The cooler 35 is fixedly connected to the outside of the connecting pipe 34. The lower end of the connecting pipe 34 is detachably connected to the oil box 38. Steam enters the interior of the connecting pipe 34. The cooler 35 cools the steam, causing the quenching oil to adhere to the inner wall of the connecting pipe 34. The quenching oil moves downward along the inner wall of the connecting pipe 34. The oil box 38 recovers the quenching oil.

[0035] Reference Figure 2 and Figure 3 The scraper 36 is located inside the connecting pipe 34 and is used to remove the quenching oil inside the connecting pipe 34. The scraper 36 includes a rotating rod 361, a scraper ring 362, a handle 363, and a barrier membrane 364. The connecting pipe 34 has a vertically opening 37. The scraper ring 362 is located inside the connecting pipe 34 and is slidably connected to the connecting pipe 34 vertically. The rotating rod 361 is vertically arranged and located inside the moving port 37. The rotating rod 361 is interference-fitted with the moving port 37. The rotating rod 361 blocks the moving port 37 and drives the scraper ring 362 to move downward. The handle 363 is fixedly connected to the side of the rotating rod 361 away from the connecting tube 34. The barrier membrane 364 is detachably connected to the side of the rotating rod 361 away from the handle 363 and is adapted to the rotating rod 361. When the connecting tube 34 needs to be cleaned, the operator turns the rotating rod 361 out of the moving port 37 through the handle 363. The operator separates the barrier membrane 364 from the rotating rod 361, thereby removing the quenching oil on the rotating rod 361. The rotating rod 361 drives the scraper ring 362 to move downward, thereby scraping the quenching oil in the connecting tube 34 into the oil box 38.

[0036] Reference Figure 1 The water-cooled pool 2 is equipped with a conveying device 4. The side of the conveying device 4 closest to the heating box 1 is located below the guide pipe 12. The side of the water-cooled pool 2 away from the heating box 1 is equipped with a box 5. The side of the conveying device 4 away from the heating box 1 is located inside the box 5.

A second support block 23 is slidably connected to the upper end of the first support block 22 along the vertical direction. The first support block 22 guides the movement of the second support block 23. A plurality of springs 24 are provided between the first support block 22 and the second support block 23. The first support block 22 and the springs 24 cooperate to support the second support block 23.

[0038] Reference Figure 4 Support plates 25 are fixed on both sides of the upper end of the second support block 23 along the width direction of the water cooling pool 2. The support plates 25 are set along the length direction of the water cooling pool 2. The support plates 25 are inclined from top to bottom along the direction from the heating box 1 to the water cooling pool 2. The support plates 25 are located below the guide tube 12 and above the conveying device 4. Multiple rollers 26 are rotatably connected between the two support plates 25. The multiple rollers 26 are arranged along the length direction of the support plates 25. When the metal comes into contact with the rollers 26, the two support plates 25 cooperate to support the multiple rollers 26. Due to the weight of the metal itself, the second support block 23 moves downward under the action of the metal's gravity and squeezes the spring 24. The metal slides on the surface of the rollers 26 and finally falls onto the conveying device 4, which helps to reduce the impact of the metal on the conveying device 4.

[0039] Reference Figure 1 The conveying device 4 includes a conveyor belt 41 and multiple baffles 42. The conveyor belt 41 is located inside the water cooling tank 2 and is arranged along the length of the water cooling tank 2.

The upper end of the conveying pipe 62 is connected to the storage bin 61, and the lower end of the conveying pipe 62 is connected to the multiple ejectors 63. The storage bins 61 store the shot, and the storage bins 61 convey the shot to the ejectors 63 through the conveying pipes 62. The ejectors 63 eject the shot onto the metal surface to remove the oxide layer.

[0041] Reference Figure 5 Two air source components 64 are fixedly connected to the two sides of the housing 5 along the width direction. The air blowing pipe 65 corresponds to the air source component 64 one by one. The air blowing pipe 65 is connected to the side of the two air source components 64 that are close to each other and is located below the ejector 63. The air source component 64 and the air blowing pipe 65 work together to blow the metal and the shot on the surface of the conveyor belt 41 to the bottom of the housing 5.

[0042] Reference Figure 5 The housing 5 has recovery components 7 on both sides along its width, which recover the projectiles inside the housing 5. A guide block 53 is fixedly installed at the lower end of the housing 5 along its length.

A discharge port 52 is opened on both sides of the lower end of the housing 5 along its width direction. The discharge port 52 is located between the two second guide plates 54, and the projectiles pass through the discharge port 52 to be transported to the outside of the housing 5.

[0043] Reference Figure 5The recycling unit 7 includes a collection bin 71, a first guide plate 72, a conveyor belt 73, and multiple collection boxes 74. The collection bin 71 is located at the lower end of the housing 5 and directly below the storage bin 61.

When the collection box 74 containing the projectiles moves above the conveyor belt 73, the collection box 74 tilts the projectiles, and the projectiles roll along the first guide plate 72 to the conveyor pipe 62.

[0044] Reference Figure 1 A collection basket 51 is provided on the side of the lower end of the box 5 away from the water cooling pool 2. The side of the conveyor belt 41 away from the heating box 1 is located above the collection basket 51. The cleaned metal is transported into the collection basket 51 to complete the recycling.

[0045] The implementation principle of an environmentally friendly heat treatment device according to an embodiment of this application is as follows: When the metal is cooled in the water-cooled pool 2, the blower 31 draws the steam in the water-cooled pool 2 into the exhaust pipe 32. The heater 33 heats the exhaust pipe 32. The steam enters the connecting pipe 34 along the exhaust pipe 32. The cooler 35 cools the steam, causing the quenching oil to adhere to the inner wall of the connecting pipe 34. The operator turns the rotating rod 361 out of the moving port 37 through the handle 363. The operator separates the barrier membrane 364 from the rotating rod 361, thereby removing the quenching oil on the rotating rod 361. The rotating rod 361 drives the scraper ring 362 to move downward, scraping the quenching oil on the inner wall of the connecting pipe 34 into the oil box 38. This device can prevent steam from being directly discharged into the air, thus improving the quality of the environment around the heat treatment equipment.
