[0013] How to use the device:

[0014] Step 1: The vacuum chamber is evacuated. The user controls the device through the control cabinet to operate. The user first uses the vacuum pump and the second connecting pipe to extract the air inside the vacuum chamber, so that the vacuum chamber is in a vacuum state. At the same time, the user controls the heating coil to start heating, and the vacuum detection sensor is used to detect the vacuum degree. When the vacuum chamber is in a vacuum state, the fourth solenoid valve is closed.

[0015] Step 2: Installation and connection. When the vacuum pump is evacuating, the user places the sealed material barrel filled with material through the movable cover and inside the support net. When one end of the transmission rod contacts the inner wall of the transmission groove, the inner wall of one end of the tube groove contacts one end of the first connecting pipe. Under the rebound force of the spring itself, the connection between the tube groove and the first connecting pipe can be more sealed, making it easier to connect the air hole and the first connecting pipe.

[0016] Step 3: Rotate for preheating. After the installation is completed, the user closes the cover door and rotates the handle. The cover door and the movable cover are closed through the movable plate, connecting rod and fixed rod. At this time, the heat generated by the heating coil preheats the material barrel and the material. At the same time, the output end of the motor rotates the connecting turntable, transmission rod and material barrel through the first gear, the second gear and the rotating tube, so that the material barrel drives the material inside to roll continuously.

[0017] Step 4: Vacuum the material barrel. After the second solenoid valve is opened, the vacuum chamber instantly removes the air inside the material barrel, so that the internal pressure of the vacuum chamber and the material barrel are the same. At this time, the second solenoid valve is closed and the third solenoid valve is opened. The remaining air inside the material barrel is removed by the vacuum pump until the material barrel is in a vacuum state, thereby reducing the time of vacuuming the material barrel and improving work efficiency.

[0018] Step 5: Heating reaction: Multiple sets of IR light sources can heat the material at different angles, while the rotating material barrel can make the material tumble continuously, so that the heating is more uniform and comprehensive, thereby accelerating the reaction speed, improving product yield and reducing energy consumption;

[0019] Step 6: After heating, the user opens the cover door and the first solenoid valve, and air enters the interior of the material barrel through the first connecting pipe, which facilitates the separation of the pipe groove and the first connecting pipe, making it easy for the user to take out the material barrel and then replace it with another set of sealed material barrels.

[0020] Step 7: Maintenance. When the user needs to maintain the heating coil, the user removes the movable cover and then removes the supporting insulation board. At this time, the heating coil and the support rod can be removed through the pull ring. The support block and roller facilitate the removal and installation of the heating coil and the support rod. When the user installs the maintained support rod and heating coil, they can be guided and positioned by the guide frame and guide plate, which facilitates the user's work.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When the user uses the device, the user controls the device to work through the control cabinet. The user first extracts the internal air of the vacuum chamber through the vacuum pump and the second connecting pipe, so that the vacuum chamber is in a vacuum state. At the same time, the user controls the heating ring to start heating, and at the same time, the vacuum degree is detected by the vacuum detection sensor. When the interior of the vacuum chamber is in a vacuum, the fourth solenoid valve is closed. When the vacuum pump is evacuating, the user puts the sealed material barrel filled with material through the movable cover and places it inside the support net, so that the transmission rod at one end of the support net is inserted into the inside of the transmission groove. Due to the rolling groove and ball bearings provided on the inner wall of the bottom end of the support net, it is convenient for the user to install and remove the material barrel. During installation, when one end of the transmission rod conflicts with the inner wall of the transmission groove, the inner wall of one end of the tube groove is in contact with the first One end of the connecting pipe is in conflict with each other. At this time, the push piece at the bottom end of the first connecting pipe slides inside the sliding hole, and the push piece compresses the spring. Under the rebound force of the spring itself, the connection between the pipe groove and the first connecting pipe can be made more sealed, which makes it easier to connect the air hole and the first connecting pipe, and also improves the sealing of the connection. After the installation is completed, the user closes the cover door and turns the handle. The cover door and the movable cover can be closed through the movable plate, the connecting rod and the fixed rod. At this time, the heat generated by the heating ring preheats the material barrel and the material. At the same time, the output end of the motor rotates the connecting turntable, the transmission rod and the material barrel through the first gear, the second gear and the rotating pipe, so that the material barrel drives the material inside to roll continuously. At the same time, the material barrel passes through the inner wall The staggered baffles make the material roll more evenly, which is convenient for preheating and subsequent heating, thereby improving the effect of preheating and subsequent heating. At the same time, the second solenoid valve is opened, and the vacuum chamber instantly draws out the air inside the material barrel, so that the internal pressure of the vacuum chamber and the material barrel are the same. At this time, the second solenoid valve is closed and the third solenoid valve is opened, and the remaining part of the material barrel is drawn out by the vacuum pump until the material barrel is in a vacuum state, thereby reducing the time of vacuuming the material barrel and improving work efficiency. Then, multiple groups of IR light source bodies can heat the material at different angles, and the rotating material barrel can make the material continue to roll comprehensively, so that the heat is more evenly and comprehensively, thereby accelerating the reaction speed, while improving the product yield and reducing Energy consumption. After the heating is completed, the user opens the cover door and the first solenoid valve, and air enters the interior of the material barrel through the first connecting pipe, which facilitates the separation of the pipe groove and the first connecting pipe, and the user can take out the material barrel, and then replace it with another set of sealed material barrels with materials. When changing materials, the heating ring can continue to heat, thereby ensuring the internal temperature of the device and shortening the subsequent preheating time. When the user needs to maintain the heating ring, the user removes the movable cover and then removes the supporting insulation plate. At this time, the heating ring and the support rod can be removed by the pull ring. The support block and roller facilitate the removal and installation of the heating ring and the support rod. When the user installs the maintained support rod and heating ring, they can guide and position them through the guide frame and guide plate.This makes the work of the user easier. The device can heat the material more evenly during preheating and heating, thereby improving the yield rate and quality of the product. It can also improve the heating efficiency, shorten the heating time, and thus reduce energy use, thereby achieving the purpose of reducing costs and increasing efficiency.

The control end of the heating coil 17 is electrically connected to the control cabinet 2 through the connector 18, which is convenient for the user to control the heating coil 17 to work. The control end of the motor 45 is electrically connected to the control cabinet 2. The transmission slot 28 and the transmission rod 29 are both cross-shaped, which is convenient for power transmission. The ends all pass through the pores of the support net 13 and point to the surface of the material barrel 23 to facilitate heating. When the inner wall of one end of the transmission rod 29 fits against the inner wall of the transmission groove 28, one end of the first connecting pipe 35 conflicts with the inner wall of the pipe groove 31. At the same time, the spring 34 is in a compressed state. The control end of the vacuum pump 40 is electrically connected to the control cabinet 2 through the vacuum detection sensor 42. The control ends of the vacuum detection sensor 42, the first solenoid valve 36, the second solenoid valve 39 and the third solenoid valve 41 are all electrically connected to the control cabinet 2, which facilitates the connection and operation of the device.

[0041] The device operates as follows:

[0042] Step 1: The vacuum chamber 37 is evacuated. The user controls the device through the control cabinet 2 to operate. The user first uses the vacuum pump 40 and the second connecting pipe 43 to extract the air inside the vacuum chamber 37, thereby making the vacuum chamber 37 in a vacuum state. At the same time, the user controls the heating coil 17 to start heating, and at the same time, the vacuum detection sensor 42 is used to detect the vacuum degree. When the interior of the vacuum chamber 37 is in a vacuum state, the fourth solenoid valve 44 is closed.

[0043] Step 2: Installation and connection. When the vacuum pump 40 is operating, the user places the sealed material barrel 23 filled with material through the movable cover 4 and into the interior of the support net 13. When one end of the transmission rod 29 contacts the inner wall of the transmission groove 28, the inner wall of one end of the tube groove 31 contacts one end of the first connecting tube 35. Under the rebound force of the spring 34, the connection between the tube groove 31 and the first connecting tube 35 is more sealed, thereby facilitating the connection between the air hole 30 and the first connecting tube 35.

[0044] Step 3: Rotate for preheating. After the installation is completed, the user closes the cover door 6 and rotates the handle 10. The cover door 6 and the movable cover 4 are closed through the movable plate 9, the connecting rod 12 and the fixed rod 11. At this time, the heat generated by the heating coil 17 preheats the material barrel 23 and the material. At the same time, the output end of the motor 45 rotates the connecting turntable 27, the transmission rod 29 and the material barrel 23 through the first gear 46, the second gear 48 and the rotating tube 47, so that the material barrel 23 drives the material inside thereof to continuously roll;

[0045] Step 4: The material barrel 23 is evacuated. After the second solenoid valve 39 is opened, the vacuum chamber 37 instantly evacuates the air inside the material barrel 23, so that the internal pressure of the vacuum chamber 37 and the material barrel 23 are the same. At this time, the second solenoid valve 39 is closed and the third solenoid valve 41 is opened. The remaining air inside the material barrel 23 is evacuated by the vacuum pump 40 until the material barrel 23 is in a vacuum state, thereby reducing the time of evacuating the material barrel 23 and improving work efficiency.

[0046] Step 5: Heating reaction: Multiple IR light source bodies 15 can heat the material at different angles, while the rotating material barrel 23 can cause the material to tumble continuously, thereby heating more evenly and comprehensively, thereby accelerating the reaction speed, improving product yield and reducing energy consumption;

[0047] Step 6: Replacing the material. After heating is completed, the user opens the cover door 6 and the first solenoid valve 36. Air enters the interior of the material barrel 23 through the first connecting pipe 35, facilitating the separation of the pipe groove 31 and the first connecting pipe 35. The user can then take out the material barrel 23 and replace it with another set of sealed material barrels 23.

[0048] Step 7: Maintenance. When the user needs to maintain the heating coil 17, the user removes the movable cover 4 and then removes the supporting insulation board 14. At this time, the heating coil 17 and the support rod 16 can be removed through the pull ring 49. The support block 19 and the roller 20 facilitate the removal and installation of the heating coil 17 and the support rod 16. When the user installs the maintained support rod 16 and heating coil 17, they can be guided and positioned by the guide frame 21 and the guide plate 22, thereby facilitating the user's work.

[0049] Working principle: When the user uses this device, the user controls the device to work through the control cabinet 2. The user first controls the vacuum pump 40 to work, and then extracts the internal air of the vacuum chamber 37 through the second connecting pipe 43, so that the vacuum chamber 37 is in a vacuum state. The vacuum state of the vacuum chamber 37 can be detected by the vacuum detection sensor 42. At the same time, the user controls the heating ring 17 to start heating. When the interior of the vacuum chamber 37 is in a vacuum, the fourth solenoid valve 44 is closed. When the vacuum pump 40 is evacuating, the user puts the sealed material barrel 23 filled with materials through the movable cover 4 and places it inside the support net 13, so that the transmission rod 29 at one end of the support net 13 is inserted into the transmission groove 28, and one end of the first connecting pipe 35 is inserted into the pipe groove 31, and the transmission rod 29 is inserted into the transmission groove 28. One end of the movable rod 29 is in conflict with the inner wall of the transmission groove 28. Due to the rolling groove 24 and the ball 25 provided on the inner wall of the bottom end of the support net 13, it is convenient for the user to install and disassemble the material barrel 23. During installation, when one end of the transmission rod 29 conflicts with the inner wall of the transmission groove 28, the inner wall of one end of the tube groove 31 conflicts with one end of the first connecting tube 35. At this time, the bottom end of the first connecting tube 35 slides inside the sliding hole 32, and the plate 33 compresses the spring 34. Under the rebound force of the spring 34 itself, the connection between the tube groove 31 and the first connecting tube 35 can be made more sealed, thereby making it easier to connect the air hole 30 and the first connecting tube 35, and at the same time, it can also improve the sealing of the connection. After the installation is completed, the user The cover door 6 is closed, and the user turns the handle 10. The movable plate 9 can be moved inside the movable groove 7 through the support block 19. The movable plate 9 drives the connecting rod 12 to move. The fixing rod 11 can be slid inside the through groove 8 through the connecting rod 12, so that one end of the fixing rod 11 extends out of the through groove 8 until the arc end of the fixing rod 11 conflicts with the inner wall of the movable cover 4. At this time, the cover door 6 and the movable cover 4 can be closed through the movable plate 9, the connecting rod 12 and the fixing rod 11. At this time, the heat generated by the heating ring 17 preheats the material barrel 23 and the material. The support net 13 can be supported by the supporting insulation plate 14, and can also be insulated. At the same time, the user controls the motor 45 to work, and the output end of the motor 45 drives the first gear The wheel 46 rotates, the first gear 46 drives the second gear 48 to rotate, the second gear 48 drives the rotating tube 47 to rotate through the rotating tube 47, and the rotating tube 47 drives the material barrel 23 to rotate through the transmission groove 28 and the transmission rod 29. Since the inner wall of the support net 13 is evenly provided with rolling grooves 24 and balls 25, the rotation of the material barrel 23 is facilitated, and the rotating material barrel 23 drives the material inside it to roll continuously. At the same time, the material barrel 23 rolls more evenly through the baffle plate 26 staggered on the inner wall, which facilitates preheating and subsequent heating, thereby improving the effect of preheating and subsequent heating. At the same time, the second solenoid valve 39 is opened, and the vacuum chamber 37 instantly draws away the air inside the material barrel 23, so that the internal pressure of the vacuum chamber 37 and the material barrel 23 are the same.At this time, the second solenoid valve 39 is closed and the third solenoid valve 41 is opened, and the remaining part inside the material barrel 23 is extracted by the vacuum pump 40 until the material barrel 23 is in a vacuum state, thereby reducing the time for vacuuming the material barrel 23 and improving work efficiency. Then, the material can be heated at different angles through multiple groups of IR light source bodies 15. At this time, the heating ring 17 can also heat and keep the material warm. At the same time, the rotating material barrel 23 can make the material continue to roll all over, so that the heating is more uniform and comprehensive, thereby accelerating the reaction speed, while improving the product yield and reducing energy consumption. After the heating is completed, the user opens the cover door 6 and the first solenoid valve 36, and air enters the interior of the material barrel 23 through the first connecting pipe 35, which facilitates the separation of the pipe groove 31 and the first connecting pipe 35, making it convenient for the user to The material barrel 23 is taken out, and then another set of material barrels 23 with the material inserted and sealed can be replaced. When the user needs to maintain the heating ring 17, the user removes the movable cover 4 and then removes the supporting insulation plate 14. At this time, the heating ring 17 and the support rod 16 can be removed through the pull ring 49. The support block 19 and the roller 20 facilitate the removal and installation of the heating ring 17 and the support rod 16. When the user installs the maintained support rod 16 and the heating ring 17, they can be guided and positioned by the guide frame 21 and the guide plate 22, which facilitates the user's work. This device can make the material heated more evenly during preheating and heating, thereby improving the product yield and quality. At the same time, it can also improve the heating efficiency, shorten the heating time, thereby reducing energy use, and thus achieving the purpose of reducing costs and increasing efficiency.

A method for operating a reduction furnace heating device having a multi-directional IR light source according to any one of claims 1 to 7, characterized in that: Step 1: The vacuum chamber (37) is evacuated. The user controls the device to operate through the control cabinet (2). The user first extracts the air inside the vacuum chamber (37) through the vacuum pump (40) and the second connecting pipe (43), thereby placing the vacuum chamber (37) in a vacuum state. At the same time, the user controls the heating coil (17) to start heating, and at the same time, the vacuum degree is detected through the vacuum detection sensor (42). When the interior of the vacuum chamber (37) is in a vacuum, the fourth solenoid valve (44) is closed. Step 2: Installation and connection. When the vacuum pump (40) is evacuating, the user places the sealed material barrel (23) filled with material through the movable cover (4) inside the support net (13). When one end of the transmission rod (29) contacts the inner wall of the transmission groove (28), the inner wall of one end of the pipe groove (31) contacts one end of the first connecting pipe (35).

After the second solenoid valve (39) is opened, the vacuum chamber (37) instantly draws out the air inside the material barrel (23), so that the internal pressure of the vacuum chamber (37) and the material barrel (23) are the same. At this time, the second solenoid valve (39) is closed and the third solenoid valve (41) is opened. The remaining part inside the material barrel (23) is drawn out by the vacuum pump (40) until the material barrel (23) is in a vacuum state, thereby reducing the time for vacuuming the material barrel (23) and improving work efficiency. Step 5: Heating reaction, through multiple sets of IR light source bodies (15), the material can be heated at different angles, and at the same time, the rotating material barrel (23) can make the material continuously roll over, so that the heating is more uniform and comprehensive, thereby accelerating the reaction speed, improving the product yield and reducing energy consumption; Step 6: Replacing the material. After heating is completed, the user opens the cover door (6) and the first solenoid valve (36). Air enters the interior of the material barrel (23) through the first connecting pipe (35), facilitating the separation of the pipe groove (31) and the first connecting pipe (35). This facilitates the user to take out the material barrel (23) and then replace it with another set of material barrels (23) that have been sealed and loaded with materials. Step 7: Maintenance.
