[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0025] like Figure 1-3As shown, the utility model provides a heat storage catalytic oxidation furnace that is easy to maintain, including a furnace body 1 and a preheating box 2, the furnace body 1 is connected to the preheating box 2, one side of the outer wall of the preheating box 2 is provided with an air outlet pipe 3, the preheating box 2 is provided with a serpentine pipe 4, one end of the serpentine pipe 4 extends to the bottom of the preheating box 2, and the other end of the serpentine pipe 4 extends to the top of the preheating box 2 and is connected to the furnace body 1; a heating pipe 5 is provided in the furnace body 1, a through groove 6 is opened on one side of the outer wall of the furnace body 1, a sliding block 7 is provided in the through groove 6, a bracket 8 for placing a catalyst is provided on the outer wall of the sliding block 7 inside the furnace body 1, a baffle 9 is detachably connected to the side of the outer wall of the bracket 8 away from the sliding block 7, a first magnet 10 is provided on the side of the outer wall of the baffle 9 close to the bracket 8, a second magnet 11 is provided on one side of the inner wall of the through groove 6, the first magnet 10 and the second magnet 11 are opposite in magnetism on the adjacent side of the outer wall, and a limiting mechanism is provided inside the sliding block 7.
[0026] Specifically, during operation, the waste gas to be treated is introduced from one end of the serpentine pipe 4, and then the waste gas enters the interior of the preheating box 2 for preheating. The serpentine pipe 4 can prolong the time of the waste gas in the preheating box 2 to ensure the preheating effect of the waste gas. After the waste gas completes the preheating work in the preheating box 2, it is input into the interior of the furnace body 1, and the heating pipe 5 starts to work to heat the waste gas. The heated waste gas contacts the catalyst to treat the waste gas. The high-temperature waste gas after treatment enters the interior of the preheating box 2 to preheat the waste gas in the serpentine pipe 4. Finally, the waste gas is passed through the preheating box 2. The exhaust gas is discharged through the exhaust pipe 3 to complete the exhaust gas treatment work; when the working time of the device is too long and the catalyst inside the bracket 8 needs to be replaced, the limiting mechanism inside the slider 7 can be removed at this time, so that the slider 7 can move relative to the through slot 6, and the slider 7 is pulled outward, thereby driving the bracket 8 and the catalyst to move toward the outside of the furnace body 1, and the baffle 9 moves with the bracket 8, and the first magnet 10 moves with the baffle 9, so as to approach the second magnet 11. As the movement progresses, the first magnet 10 contacts the second magnet 11, and the first magnet 10 contacts the catalyst. The magnetism of the adjacent side of the outer wall of the second magnet 11 is opposite, so the two fit together, so that the baffle 9 fits the inner wall of the furnace body 1, and the baffle 9 blocks the through slot 6 to prevent the exhaust gas from flowing out of the through slot 6. At this time, the bracket 8 and the catalyst move to the outside of the furnace body 1, and the catalyst can be replaced without stopping the normal operation of the furnace body 1. At the same time, the baffle 9 prevents the exhaust gas from leaking from the through slot 6. When the catalyst replacement work is completed, the slider 7 and the bracket 8 are manually pushed to return to their original positions, and the bracket 8 pushes the baffle 9 to move, and the magnetic field of the first magnet 10 and the second magnet 11 is overcome by external force. , so that the baffle 9 moves with the bracket 8. When the slider 7 moves to the inside of the through groove 6 again, the position of the slider 7 is fixed again by the limiting mechanism to complete the replacement of the catalyst; the number of the through grooves 6 is two, and the heating tube 5 is located above the two through grooves 6. Synchronously, the number of the brackets 8 is two. When one bracket 8 is taken out to replace the catalyst inside it, the other bracket 8 can still work. The two brackets 8 can work alternately, thereby ensuring that the device can continuously perform exhaust gas treatment work without stopping the operation of the furnace body 1, thereby ensuring the practicality of the device.
[0027] The utility model cooperates with the slider 7, the baffle 9, the first magnet 10 and the second magnet 11. When the catalyst needs to be replaced, the slider 7 and the bracket 8 can be pulled out from the through slot 6, so that the baffle 9 is moved closer to the through slot 6. When the first magnet 10 and the second magnet 11 are fitted together, the baffle 9 is fixed to one side of the through slot 6, so as to block the through slot 6 and prevent the exhaust gas from flowing out of the through slot 6. At this time, the catalyst in the bracket 8 can be replaced, which is convenient for replacing the catalyst. At the same time, the baffle 9 prevents the exhaust gas from leaking from the through slot 6 without stopping the operation of the furnace body 1, thereby ensuring the practicability and working efficiency of the device.
[0028] like Figure 1 and Figure 3 As shown, in an embodiment, a third magnet 12 is provided on the outer wall of the bracket 8 close to the first magnet 10, and the third magnet 12 has opposite magnetism to the adjacent side of the outer wall of the first magnet 10. The bracket 8 is detachably connected to the baffle 9 through the cooperation of the third magnet 12 and the first magnet 10. When the bracket 8 is taken out of the furnace body 1, after the first magnet 10 and the second magnet 11 are fitted, force can be continued to be applied outward to remove the bracket 8 from the baffle 9 for replacement, so that the bracket 8 is easy to disassemble, thereby ensuring the practicability of the device.
[0029] In one embodiment, a plurality of through holes are opened on the inner wall of the furnace body 1 on one side of the baffle 9, and a return spring 13 is arranged in the through hole. When the slider 7 moves completely to the inside of the through slot 6, the baffle 9 is located on one side of the return spring 13, and the return spring 13 is in a compressed state. When the limiting mechanism is removed, the return spring 13 can push the baffle 9, the bracket 8 and the slider 7 to move toward the outside of the furnace body 1, so as to facilitate the removal of the slider 7 from the through slot 6, thereby ensuring the convenience of the device.
[0030] In one embodiment, the inner wall of the furnace body 1 is provided with a plurality of guide rods 14 on one side of the baffle 9, and the guide rods 14 are slidably connected to the baffle 9. When the bracket 8 drives the baffle 9 to move, the guide rods 14 guide the baffle 9 to ensure the stability of the baffle 9 during movement and prevent the baffle 9 from falling to the bottom of the inner wall of the furnace body 1 when the baffle 9 is separated from the bracket 8, thereby ensuring the safety of the device; a groove matching the bracket 8 is provided on one side of the outer wall of the first magnet 10, and the groove is used to have a certain positioning effect on the bracket 8 and the first magnet 10.
[0031] like Figure 3As shown, in one embodiment, the limiting mechanism includes a cavity 15 opened inside the slider 7, a screw rod 16 is rotatably connected to one side of the inner wall of the cavity 15, and a movable block 18 is threadedly connected to the outer wall of the screw rod 16, and the inner wall of the cavity 15 is symmetrically provided with sliding blocks 19 on both sides of the screw rod 16, and a push rod 20 is rotatably connected to the outer wall of the block 19 close to the movable block 18, and one end of the push rod 20 is rotatably connected to the outer wall of the movable block 18, and a groove is opened on the inner wall of the through groove 6 on one side of the block 19; one end of the screw rod 16 extends to the outside of the slider 7 and is sleeved with a handle 17.
[0032] When the slider 7 needs to be taken out of the through slot 6, the handle 17 can be rotated at this time, and the handle 17 drives the screw rod 16 to rotate, and the screw rod 16 drives the movable block 18 to move toward the handle 17, and the movable block 18 drives the clamping block 19 to move toward the inside of the cavity 15 through the push rod 20. The two clamping blocks 19 are close to each other. When the clamping block 19 moves to the outside of the clamping slot, the slider 7 can be taken out of the through slot 6. When the slider 7 needs to be fixed inside the through slot 6, the clamping block 19 is moved to one side of the clamping slot. At this time, the handle 17 is rotated in the opposite direction to drive the screw rod 16 to rotate in the opposite direction, thereby driving the movable block 18 to move away from the handle 17. The movable block 18 pushes the two clamping blocks 19 away from each other through the push rod 20, so that the clamping block 19 moves to the inside of the clamping slot, and the clamping block 19 cooperates with the clamping slot to fix the relative position of the slider 7 and the through slot 6, so that the device is easy to disassemble and the convenience of the device is guaranteed.
[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
