Technical Field
[0001] This application relates to the technical field of oxidation furnaces, and in particular to an electrically heated rotary regenerative oxidation furnace. Background Technology
[0002] Currently, waste gas incinerators are also called waste gas oxidation furnaces. Waste gas incinerators are devices that use the heat generated by the combustion of auxiliary fuel to raise the temperature of combustible and harmful gases to the reaction temperature, thereby causing oxidation and decomposition. Waste gas incinerators are divided into direct-fired and regenerative types. In fact, the principles of direct-fired and regenerative types are the same; the only difference is whether there is a heat storage material in the furnace. Waste gas incinerators are suitable for the treatment of waste gas from spraying and drying equipment, as well as the purification of harmful gases emitted from industries such as petrochemicals and pharmaceuticals.
[0003] The prior art can be referenced in Chinese utility model patent with authorization announcement number CN214275764U, which discloses a rotary multi-chamber RTO, including a furnace body, a burner is provided on the top of the furnace body, a combustion chamber and a heat storage chamber are provided inside the furnace body, and a rotary distribution valve is connected to the bottom of the heat storage chamber. An air outlet chamber is provided at the bottom of the furnace body, and an exhaust gas inlet fan is connected to the left side of the furnace body. An exhaust fan is provided on the right side of the furnace body. An air jet nozzle is also provided inside the furnace body, and a protective mechanism is provided outside the rotary distribution valve.
[0004] However, existing technology heats the furnace body through a burner, which uses natural gas as fuel. This causes pollution and poses safety risks, making it inconvenient to heat the furnace body. Summary of the Invention
[0005] To facilitate heating of the furnace body, this application provides an electrically heated rotary regenerative oxidation furnace, employing the following technical solution: An electrically heated rotary regenerative oxidizer includes a furnace body, a heating chamber, a regenerating chamber, a rotary distribution valve, and a waste gas inlet fan. The top of the furnace body has multiple first through holes, each of which is slidably connected to a set of heating plates. Each set of heating plates includes two heating plates. A movable frame is mounted on the top of the multiple sets of heating plates. A drive mechanism for moving the movable frame is mounted on the outer wall of the furnace body. The drive mechanism includes a fixed frame mounted on the outer wall of the furnace body, a drive motor mounted on the top of the fixed frame, a lead screw rotatably connected to the fixed frame and mounted on the output shaft of the drive motor, and a drive guide rod fixed to the fixed frame. The movable frame is threadedly connected to the lead screw and slidably connected to the drive guide rod.
[0006] By adopting the above technical solution, the electric heating plate is designed to facilitate heating of the furnace body. When the electric heating plate needs to be cleaned, the drive motor is started first. At this time, the output shaft of the drive motor drives the lead screw to rotate. The rotation of the lead screw drives the moving frame to move upward. The upward movement of the moving frame drives the electric heating plate to move upward, thus removing the electric heating plate from the furnace body. This allows the electric heating plate to be cleaned, reducing the amount of debris adhering to the surface of the electric heating plate and thus improving the heating efficiency of the electric heating plate.
[0007] Optionally, the mounting bracket is equipped with multiple cleaning devices for cleaning multiple sets of heating plates.
[0008] By adopting the above technical solution, the cleaning device facilitates the cleaning of the electric heating plate.

[0010] By adopting the above technical solution, when it is necessary to clean the electric heating plate, the air pump is first started, and then the air supply pipe supplies air to multiple nozzles. Then, the electric heating plate can be cleaned under the action of multiple nozzles. In summary, the cleaning device is designed to facilitate the cleaning of the electric heating plate.
[0011] Optionally, two sets of dust collection devices are installed on the outer wall of the furnace body.
[0012] By adopting the above technical solution, the dust collection device can be easily processed to remove the dust that is cleaned off the heating plate from the nozzle.
[0013] Optionally, each set of the dust collection device includes a processing box installed on the outer wall of the furnace body, a dust collection hood installed above the processing box, and a negative pressure pump installed below the processing box; the bottom of the dust collection hood is connected to the top of the processing box through a pipe, the air inlet of the negative pressure pump is connected to the bottom of the processing box through a pipe, the processing box has an opening on the side away from the furnace body, a cover plate is bolted to the opening, a filter frame is fixed to the side of the cover plate near the furnace body, and a sealing plate is installed between the cover plate and the processing box.
[0014] By adopting the above technical solution, when dust needs to be treated, the negative pressure pump is first started, at which time the dust hood generates suction, and then the dust enters the filter frame under the action of the dust hood; when the dust in the filter frame needs to be treated, the cover plate is first loosened with a tool, and then the cover plate and the filter frame are removed together, so that the dust can be treated; in summary, the dust collection device is designed to facilitate the cleaning of dust.
[0015] Optionally, the fixing frame is equipped with two sets of blocking devices for blocking multiple first through holes. Each set of blocking devices includes a blocking frame installed on the top of the fixing frame, a vertical plate slidably connected to the blocking frame, a blocking plate installed at the bottom of the vertical plate, and a driving mechanism installed on the blocking frame for driving the vertical plate to move. The vertical plate does not interfere with the cleaning device. In the initial state, the two blocking plates block the openings of the two dust hoods respectively.
[0016] By adopting the above technical solution, when the moving frame drives the heating plate upward, the moving frame and the two sets of driving mechanisms work together to drive the two vertical plates to move towards each other. The movement of the two vertical plates towards each other drives the two shielding plates to move towards each other, which can block multiple first through holes. Thus, when cleaning the heating plate, it can reduce the amount of debris entering the furnace through the first through holes. In summary, the shielding device facilitates the blocking of multiple first through holes.
[0017] Optionally, each set of driving mechanisms includes a receiving groove at the bottom of the shielding frame, a driving guide rod fixed to the inner wall of the receiving groove, a through hole at the side wall of the receiving groove, a rotating tube rotatably connected to the inner wall of the through hole, and a driving rod disposed in the rotating tube; the vertical plate is slidably connected to the driving guide rod, the side wall of the driving rod is provided with multiple spiral blocks, the inner wall of the rotating tube is provided with multiple spiral grooves, and the spiral blocks match the spiral grooves; a gear is fixedly sleeved on the outer wall of the rotating tube, a rack is fixedly connected to the side of the vertical plate near the rotating tube, the two racks are staggered and do not interfere, the gear meshes with the rack, a limit ring is threadedly connected to the top of the driving rod, a bearing plate is fixedly connected to the bottom of the driving rod, the moving frame can push the bearing plate to move upward, and a driving spring is fixedly connected between the bearing plate and the shielding frame.
[0018] By adopting the above technical solution, the upward movement of the moving frame drives the upward movement of the bearing plate, which in turn drives the upward movement of the drive rod. Then, under the action of the spiral block and the spiral groove, the drive rod drives the rotating tube to rotate. The rotation of the rotating tube drives the gear to rotate, which in turn drives the rack to move. The movement of the rack then drives the vertical plate to move. In summary, the driving mechanism facilitates the movement of the vertical plate.
[0019] Optionally, the cleaning rack is equipped with an impact device for impacting the moving rack.
[0020] By adopting the above technical solution, the impact device is designed to facilitate impacting the moving frame, which makes it easier to shake off the dust on the heating plate.
[0021] Optionally, the impact device includes an impact frame mounted on the top of the cleaning frame, a second through hole in the impact frame, and an impact plate slidably connected to the second through hole; an impact guide rod is fixedly connected to the side of the impact frame away from the moving frame, a sliding sleeve is fixedly connected to the top of the impact plate, the sliding sleeve is slidably connected to the impact guide rod, a baffle is fixedly connected to the bottom of the impact guide rod, and an impact spring is fixedly connected between the baffle and the sliding sleeve. A power storage device for storing force on the impact plate is installed on the cleaning frame. When the power storage device acts on the impact plate, the baffle is in the second through hole, and the impact spring is in a compressed state; when the power storage device does not act on the impact plate, the end of the impact plate away from the baffle can impact the side wall of the moving frame.
[0022] By adopting the above technical solution, when the moving frame moves upward to a certain position, the moving frame can prevent the energy storage device from acting on the impact plate, and then the impact plate can impact the moving frame under the action of the impact spring; in summary, the impact device is designed to facilitate impacting the moving frame.
[0023] Optionally, the energy storage device includes a dovetail groove formed on the side of the impact frame near the movable frame, a dovetail plate slidably connected to the dovetail groove, and an energy storage spring fixed to the bottom of the dovetail plate; the end of the energy storage spring away from the dovetail plate is fixed to the top wall of the dovetail groove; an energy storage plate is fixed to the side of the dovetail plate near the movable frame, and an inclined surface is provided at the end of the impact plate near the energy storage plate. In the initial state, the energy storage plate pushes the impact plate into the second through hole under the action of the inclined surface, and the movable frame can push the energy storage plate to move upward.
[0024] By adopting the above technical solution, when the moving frame moves upward to a certain position, it can drive the energy storage plate to move upward. The upward movement of the energy storage plate drives the dovetail plate to move upward. At this time, the energy storage spring is in a compressed state, and then the impact plate impacts the moving frame under the action of the impact spring. When the moving frame does not act on the energy storage plate, the energy storage plate moves downward under the action of the energy storage spring. Then, the energy storage plate drives the impact plate to move into the second through hole under the action of the inclined plane. The movement of the impact plate into the second through hole drives the sliding sleeve to move. The movement of the sliding sleeve presses against the impact spring, thus facilitating the energy storage of the impact plate. In summary, the energy storage device facilitates the energy storage of the impact plate.
[0025] In summary, this application includes at least one of the following beneficial technical effects: The heating plate is designed to facilitate heating of the furnace body. When cleaning the heating plate is required, the drive motor is started first. The output shaft of the drive motor drives the lead screw to rotate, which in turn drives the moving frame to move upward. The upward movement of the moving frame moves the heating plate upward, thus removing the heating plate from the furnace body for cleaning. This reduces the amount of debris adhering to the surface of the heating plate, thereby improving its heating efficiency. Attached Figure Description

The movable frame 21 slides vertically and is connected to the drive guide rod 34. The electric heating plate 2 is provided to facilitate heating inside the furnace body 1. When it is necessary to clean the electric heating plate 2, the drive motor 32 is started first. At this time, the output shaft of the drive motor 32 drives the lead screw 33 to rotate. The rotation of the lead screw 33 drives the movable frame 21 to move upward. The upward movement of the movable frame 21 drives the electric heating plate 2 to move upward, thus removing the electric heating plate 2 from inside the furnace body 1. This allows the electric heating plate 2 to be cleaned, reducing the amount of debris adhering to the surface of the electric heating plate 2 and thus improving the heating efficiency of the electric heating plate 2.

Each cleaning device 4 includes a cleaning frame 41 mounted on the mounting frame 31, an air blowing pipe 42 mounted on the cleaning frame 41, and multiple nozzles 43 connected sequentially along the axial direction of the air blowing pipe 42. An air pump 44 is mounted on the cleaning frame 41, and the air outlet of the air pump 44 is connected to the air blowing pipe 42. When it is necessary to clean the heating plate 2, the air pump 44 is started first, and then the air supply pipe supplies air to the multiple nozzles 43. Then, the heating plate 2 can be cleaned under the action of the multiple nozzles 43. In summary, the cleaning device 4 facilitates the cleaning of the heating plate 2.
[0037] Reference Figure 2 and Figure 3 Two sets of dust collection devices 5 are installed on the outer wall of the furnace body 1. The dust collection devices 5 are designed to facilitate the treatment of dust cleaned off the electric heating plate 2 by the nozzle 43.
[0038] Reference Figure 2 and Figure 3 Each set of dust collection devices 5 includes a processing box 51 installed on the outer wall of the furnace body 1, a dust collection hood 52 installed above the processing box 51, and a negative pressure pump 53 installed below the processing box 51.

The air inlet of the negative pressure pump 53 is connected to the bottom of the processing box 51 through a pipe. The processing box 51 has an opening on the side away from the furnace body 1. A cover plate 54 is bolted to the opening. A filter frame 55 is fixed to the side of the cover plate 54 near the furnace body 1. A sealing plate 56 is installed between the cover plate 54 and the processing box 51. When dust needs to be cleaned, the negative pressure pump 53 is started first. At this time, the dust suction hood 52 generates suction, and the dust enters the filter frame 55 under the action of the dust suction hood 52. When the dust in the filter frame 55 needs to be cleaned, the cover plate 54 is loosened with a tool, and then the cover plate 54 and the filter frame 55 are removed together, so that the dust can be cleaned. In summary, the dust suction device 5 is designed to facilitate the cleaning of dust.

The vertical plate 62 does not interfere with the cleaning device 4. In the initial state, the two shielding plates 63 respectively shield the openings of the two dust hoods 52. When the moving frame 21 moves the heating plate 2 upward, the moving frame 21 and the two sets of driving mechanisms work together to drive the two vertical plates 62 to move towards each other. The two vertical plates 62 moving towards each other drive the two shielding plates 63 to move towards each other, which can block the multiple first through holes 15. Thus, when cleaning the heating plate 2, it can reduce the amount of debris entering the furnace body 1 through the first through holes 15. In summary, the shielding device 6 is provided to facilitate the blocking of multiple first through holes 15.

The upward movement of the movable frame 21 causes the bearing plate 663 to move upward, which in turn causes the drive rod 66 to move upward. Then, under the action of the spiral block 661 and the spiral groove 651, the drive rod 66 drives the rotating tube 65 to rotate. The rotation of the rotating tube 65 drives the gear 67 to rotate, and the rotation of the gear 67 drives the rack 68 to move. The movement of the rack 68 can drive the vertical plate 62 to move. In summary, the driving mechanism is designed to facilitate the movement of the vertical plate 62.
[0041] Reference Figure 3 and Figure 5The cleaning rack 41 is equipped with an impact device 7 for impacting the movable rack 21. The impact device 7 facilitates impacting the movable rack 21, thereby shaking off the dust on the heating plate 2.

When the power storage device 8 acts on the impact plate 72, the baffle 75 is in the second through hole 711 and the impact spring 76 is in a compressed state. When the power storage device 8 does not act on the impact plate 72, the end of the impact plate 72 away from the baffle 75 can impact the side wall of the moving frame 21. When the movable frame 21 moves upward to a certain position, the movable frame 21 can prevent the energy storage device 8 from acting on the impact plate 72. Then, the impact plate 72 can impact the movable frame 21 under the action of the impact spring 76. In summary, the impact device 7 is provided to facilitate the impact on the movable frame 21.

Then, the impact plate 72 impacts the movable frame 21 under the action of the impact spring 76. When the movable frame 21 does not act on the energy storage plate 84, the energy storage plate 84 moves downward under the action of the energy storage spring 83. Then, the energy storage plate 84 drives the impact plate 72 to move into the second through hole 711 under the action of the inclined plane 721. The movement of the impact plate 72 into the second through hole 711 causes the sliding sleeve 74 to move. The movement of the sliding sleeve 74 presses against the impact spring 76, thus facilitating the energy storage of the impact plate 72. In summary, the energy storage device 8 facilitates the energy storage of the impact plate 72.
