The ceramic insulating sleeve has an internal stainless steel acid-resistant wire, and ceramic insulating rings are evenly distributed on its side surface. The ceramic insulating rings have grooves. The high thermal resistance alloy wire is ring-shaped and wound around a number of ceramic insulating sleeves on the surface of ceramic insulating sleeves from the inner ring to the outer ring. The high thermal resistance alloy wire is located in the groove.

[0005] Preferably, a first motor is connected to the upper surface of the fixed base, a lead screw is connected to the output end of the first motor, a fixed rod is connected inside the fixed base, and the fixed rod is located behind the lead screw.

[0006] Preferably, both the lead screw and the fixed rod have movable rings movably connected to their side surfaces, and a connecting rod is connected to the side surface of the movable ring. The end of the connecting rod away from the movable ring extends out of the interior of the fixed seat, and the connecting rod is slidably connected to the fixed seat.

[0007] Preferably, a fixing plate is connected to the side surface of the connecting rod, and the fixing plate is located on the right side of the fixing seat. An electric push rod is movably connected to the right side of the fixing plate via a bearing.

[0008] Preferably, the end of the connecting rod away from the fixed base is connected to a connecting plate, and the connecting plate is located to the right of the fixed plate. The rear surface of the connecting plate is rotatably connected to a movable short rod, and the end of the movable short rod away from the connecting plate is connected to a connecting short plate, and the connecting short plate is located behind the connecting plate.

[0009] Preferably, a second motor is connected to the left side of the connecting short plate, and the left side of the second motor is movably connected to the output end of the electric push rod through a bearing. A rotating rod is connected to the output end of the second motor, and the rotating rod is connected through the connecting short plate.

[0010] Preferably, the end of the rotating rod away from the connecting short plate is connected to a threaded rod, and the threaded rod is sleeved with a fixing ring, and both sides of the fixing ring are provided with fitting grooves.

[0011] Preferably, a limiting ring is threadedly connected to the side surface of the threaded rod, a handle is connected to the side surface of the limiting ring, and a circular groove is provided on the right side surface of the limiting ring, with a sliding block slidably connected inside the circular groove.

[0012] Preferably, a connecting rod is connected to the right side of the sliding block, and the connecting rod is located on the right side of the limiting ring. A fixing frame is connected to the end of the connecting rod away from the limiting ring, and both the fixing frame and the connecting rod are fitted into the fitting groove.

[0013] Preferably, a first limiting block is fitted onto the upper surface of the fixed frame, a spring is connected to the lower surface of the first limiting block, a second limiting block is connected to the end of the spring away from the first limiting block, and both the second limiting block and the first limiting block are fitted into the interior of the fitting groove.

[0014] Compared with the prior art, the present invention provides an embedded electric heater, which has the following beneficial effects: 1. By using the ceramic insulating sleeve and high thermal resistance alloy wire, the electric heater embedded in the adsorbent is activated to energize both ends of the high thermal resistance alloy wire, causing the high thermal resistance alloy wire to heat up and directly heat the adsorbent to regenerate it. The high thermal resistance alloy wire is wound with uniform pressure to ensure heating reliability.

[0015] 2. By using the set limiting ring, connecting short rod, first limiting block and second limiting block, the limiting ring is fitted onto the side surface of the threaded rod. Pulling the handle makes the limiting ring rotate, thus moving the limiting ring to the left. At the same time, pulling the connecting short rod causes the sliding block to move upward and downward inside the annular groove, aligning with the fitting groove. The fixing frame and connecting short rod are fitted into the fitting groove. The first limiting block and the second limiting block are pressed, causing them to move into the fixing frame. The spring is compressed, and the spring's stress rebounds, causing the first limiting block and the second limiting block to fit against the inner wall of the fitting groove, thus limiting and fixing the fixing ring. This allows for quick installation or disassembly of the electric heater, facilitating subsequent maintenance or replacement of the electric heater.

[0016] 3. By using the fixed plate, movable short rod, and connecting short plate, the first motor is started to rotate the lead screw, causing the moving ring to move upward, which in turn moves the connecting long rod upward. This causes the connecting plate to move the electric heater upward, positioning the electric heater above the container containing the adsorbent. The electric push rod is then started to extend to the right, pushing the second motor to swing upward. This causes the connecting short plate to flip, rotating the movable short rod and causing the rotating rod to swing the threaded rod downward, positioning the electric heater vertically above the container containing the adsorbent. The first motor is then started in the opposite direction, causing the connecting long rod to move the electric heater downward and embed it inside the adsorbent. This allows for electrically heated adsorption of adsorbent containers of different heights. Attached Figure Description

[0020] The ceramic insulating sleeve 27 has ceramic insulating rings 30 evenly distributed on its side surface. The ceramic insulating rings 30 are provided with grooves 29. The grooves are annular, which facilitates the placement of high thermal resistance alloy wire and ensures reliable positioning and connection.

[0021] The high thermal resistance alloy wire 31 is annular and is wound around the ceramic insulating collar 30 on the surface of several ceramic insulating sleeves 27 from the inner circle to the outer circle. The high thermal resistance alloy wire 31 is located in the groove 29.

[0022] In a special processing environment, an electric heater is embedded in the adsorbent. The electric heater is activated inside the adsorbent (such as activated alumina, molecular sieve, etc.). When electricity is applied to both ends of the high thermal resistance alloy wire 29, the high thermal resistance alloy wire 29 heats up and directly heats the adsorbent to regenerate it.

A movable ring 6 is movably connected to the side surfaces of both the lead screw 4 and the fixed rod 5. A connecting rod 7 is connected to the side surface of the movable ring 6, and the end of the connecting rod 7 away from the movable ring 6 extends out of the interior of the fixed base 2. The connecting rod 7 is slidably connected to the fixed base 2. A fixed plate 13 is connected to the side surface of the connecting rod 7, and the fixed plate 13 is located on the right side of the fixed base 2. An electric push rod 14 is movably connected to the right side of the fixed plate 13 via a bearing. A connecting plate 8 is connected to the end of the connecting rod 7 away from the fixed base 2, and the connecting plate 8 is located on the right side of the fixed plate 13. A movable short rod 9 is rotatably connected to the rear surface of the connecting plate 8. The end of the movable short rod 9 furthest from the connecting plate 8 is connected to the connecting short plate 10, which is located behind the connecting plate 8. Before adsorption, the first motor 3 is started to rotate the lead screw 4, thereby moving the moving ring 6 upward, which in turn moves the connecting long rod 7 upward, causing the connecting plate 8 to move the electric heater upward. The electric heater is then moved above the container containing the adsorbent. The electric push rod 14 is started to extend to the right, pushing the second motor 11 to swing upward, causing the connecting short plate 10 to flip and rotate the movable short rod 9. This causes the rotating rod 12 to swing the threaded rod 15 downward, placing the electric heater vertically above the container containing the adsorbent. Then, the first motor 3 is started to rotate in the opposite direction, causing the connecting long rod 7 to move the electric heater downward and embed it inside the adsorbent for adsorption processing.

[0024] A second motor 11 is connected to the left side of the connecting short plate 10, and the left side of the second motor 11 is movably connected to the output end of the electric push rod 14 via a bearing. A rotating rod 12 is connected to the output end of the second motor 11, and the rotating rod 12 is connected through the connecting short plate 10. A threaded rod 15 is connected to the end of the rotating rod 12 away from the connecting short plate 10, and the threaded rod 15 is sleeved with a fixing ring 25. Both sides of the fixing ring 25 are provided with fitting grooves 26. A limit ring 16 is threadedly connected to the side surface of the threaded rod 15. The limit ring 16... A grip bar 17 is connected to the side surface. A circular groove 18 is provided on the right side of the limiting ring 16. A sliding block 19 is slidably connected inside the circular groove 18. A connecting short rod 20 is connected to the right side of the sliding block 19, and the connecting short rod 20 is located on the right side of the limiting ring 16. A fixing frame 21 is connected to the end of the connecting short rod 20 away from the limiting ring 16. Both the fixing frame 21 and the connecting short rod 20 are fitted into the fitting groove 26. A first limiting block 22 is fitted into the upper surface of the fixing frame 21, and a spring is connected to the lower surface of the first limiting block 22. 23. The end of spring 23 away from the first limiting block 22 is connected to a second limiting block 24, and both the second limiting block 24 and the first limiting block 22 are in contact with the inside of the fitting groove 26. Before adsorption processing, the fixing ring 25 is placed on the side surface of the threaded rod 15, and then the limiting ring 16 is placed on the side surface of the threaded rod 15. Pulling the handle 17 causes the limiting ring 16 to rotate, thereby moving the limiting ring 16 to the left. At the same time, pulling the connecting short rod 20 causes the sliding block 19 to move upward and downward inside the annular groove 18, engaging with the fitting groove 26. Align the fitting groove 26, fit the fixing frame 21 and the connecting short rod 20 into the fitting groove 26, press the first limiting block 22 and the second limiting block 24 to move them into the fixing frame 21, press the spring 23, and use the stress rebound of the spring 23 to make the first limiting block 22 and the second limiting block 24 fit against the inner wall of the fitting groove 26, and limit and fix the fixing ring 25.

[0025] In use, the fixing ring 25 is fitted onto the side surface of the threaded rod 15, and then the limiting ring 16 is fitted onto the side surface of the threaded rod 15. Pulling the handle 17 causes the limiting ring 16 to rotate, thus moving the limiting ring 16 to the left. At the same time, pulling the connecting short rod 20 causes the sliding block 19 to move upward and downward inside the annular groove 18, aligning it with the fitting groove 26. The fixing frame 21 and the connecting short rod 20 are fitted into the fitting groove 26. The first limiting block 22 and the second limiting block 24 are pressed, causing them to move into the fixing frame 21. The spring 23 is pressed, and the stress of the spring 23 rebounds, causing the first limiting block 22 and the second limiting block 24 to fit against the inner wall of the fitting groove 26, thus limiting and fixing the fixing ring 25. The first motor 3 is started, causing the lead screw 4 to rotate, thus moving the ring. 6. Move upwards, causing the connecting rod 7 to move upwards, which in turn causes the connecting plate 8 to move the electric heater upwards, moving the electric heater above the container containing the adsorbent. Start the electric push rod 14 to extend it to the right, pushing the second motor 11 to swing upwards, causing the connecting short plate 10 to flip and drive the movable short rod 9 to rotate, thereby causing the rotating rod 12 to drive the threaded rod 15 to swing downwards, so that the electric heater is placed vertically above the container containing the adsorbent. Then start the first motor 3 to rotate in the opposite direction, causing the connecting rod 7 to move the electric heater downwards and embed it inside the adsorbent.
