[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-8 As shown, a thermal cycle RTO catalytic incineration purification device includes a heat storage chamber 1 arranged at the bottom of a combustion furnace:

[0030] A base 3 for placing ceramic fillers is driven to slide vertically inside the heat storage chamber 1 and has a groove thereon;

[0031] A plurality of clamps 4 fixedly disposed on the base 3;

[0032] A hook tongue 6 is movably arranged on the inner wall of the heat storage chamber 1, and an upper hook portion 61 and a lower bent portion 62 are arranged at a first end thereof, and the upper hook portion 61 forms a blocking fit with the clamp 4 to enable the hook tongue 6 to move;

[0033] The elastic member 7 is arranged on the inner wall of the heat storage chamber 1, and is squeezed into the groove by the movement of the hook tongue 6 to deform and fix the base 3 and the heat storage chamber 1;

[0034] Wherein: the hook tongue 6 is kept at a predetermined angle in the initial state, so that the upper hook portion 61 extends out of the inner wall of the heat storage chamber 1 .

[0035] Specifically, a rotating mechanism is provided on the base 3 to rotate the heat storage ceramic layer. When the heat storage ceramic needs to be replaced, a new heat storage ceramic filler is installed on the base 3, driving the base 3 to move vertically upward, and the clamp 4 moves accordingly and reaches the heat storage chamber 1. The clamp 4 first conflicts with the hook tongue 6 inclined in the initial state. Since the upper hook 61 extends out of the inner wall of the heat storage chamber 1 in the initial state, and the upper hook 61 and the clamp 4 form a pick-and-drop fit to enable the hook tongue 6 to move, the clamp 4 is blocked by the upper hook 61 during the upward movement. The hook tongue 6 is driven to move, and the lower bent portion 62 is located directly below the clamping member 4. During the movement of the hook tongue 6, the elastic member 7 is squeezed and pushed, so that the elastic member 7 is deformed and squeezed into the groove provided on the base 3. The base 3 and the heat storage chamber 1 are clamped by the elastic member 7 to complete the renewal of the heat storage ceramic filler. At this time, when the base 3 moves downward, the clamping member 4 will squeeze the lower bent portion 62, and support the clamping member 4 to support the base 3 through the lower bent portion 62, so that the hook tongue 6 further squeezes the elastic member 7, and the base 3 and the heat storage chamber 1 are further clamped;

[0036] When removing the base 3, it is necessary to continue to move the base 3 upward. Due to the activity of the hook tongue 6, the upper hook portion 61 no longer blocks the clamping member 4, so that the clamping member 4 is separated from the hook tongue 6 during the upward movement, and the hook tongue 6 no longer pushes the elastic member 7. The elastic member 7 recovers its deformation through elastic potential energy and comes out of the groove, and drives the hook tongue 6 to return to its initial state. At this time, the base 3 and the heat storage chamber 1 are no longer fixed, and the base 3 is moved downward until the base 3 and the heat storage ceramic layer thereon reach a height that is convenient for the staff to replace.

[0037] In the above technology, the hook tongue 6 is driven to move by moving the base 3 upward, so that the elastic member 7 is squeezed into the groove, and then the base 3 is moved upward again to unhook the hook tongue 6. The elastic member 7 recovers its deformation through elastic potential energy and escapes from the groove, and drives the hook tongue 6 to return to its initial state. Finally, the base 3 is moved downward until the base 3 and the heat storage ceramic layer thereon reach a height that is convenient for the staff to replace. The overall operation is relatively simple and very convenient.

[0038] As an embodiment further provided by the present invention, a lifting mechanism 2 is provided on the base 3 .

[0039] Specifically, the lifting mechanism 2 can accurately control the rise and fall of the base 3, further simplifying the operation of the staff. The lifting mechanism 2 can use a hydraulic cylinder or a labor-saving sprocket and manual cooperation, or other driving mechanisms known to technical personnel in this field.

[0040] As another embodiment further provided by the present invention, a T-shaped slot 5 is provided inside the heat storage chamber 1 , and a pop-up slider 63 is provided at the second end of the hook tongue 6 , and the pop-up slider 63 is slidably connected to the T-shaped slot 5 .

[0041] Specifically, Figure 5 and Figure 6As shown in the figure for reference, when the upper hook portion 61 of the hook tongue 6 is driven upward by the clamp 4, the pop-up slider 63 at the second end of the hook tongue 6 is pulled to slide from the right end to the left end of the T-slot 5. At this time, the hook tongue 6 changes from an inclined state to a vertical state, and the lower bent portion 62 is located directly below the clamp 4. Subsequently, the base 3 is no longer driven to be lifted. The base 3 moves downward under its own weight and causes the clamp 4 to move downward. After the clamp 4 moves down a certain distance, it presses against the lower bent portion 62, so that the pop-up slider 63 of the hook tongue 6 squeezes the elastic member 7 downward along the T-slot 5. The elastic member 7 is squeezed into the groove, so that the base 3 and the heat storage chamber 1 are fixed.

[0042] As another embodiment further provided by the present invention, the T-shaped slot 5 includes a transverse slot and a vertically arranged deep slot 51 , and an arc-shaped stopper 52 is arranged on the deep slot 51 .

[0043] Specifically, Figure 5 and Figure 6 As shown for reference, the interior of the deep groove 51 is an inclined arc surface, the top side of the arc stopper 52 is an arc surface, and the pop-up slider 63 slides from the right end to the left end of the T-slot 5, and finally stops in the middle of the deep groove 51 of the T-slot 5. Since the arc stopper 52 blocks the pop-up slider 63, the pop-up slider 63 shrinks a distance until it intersects with the side of the arc stopper 52. At this time, the arc stopper 52 no longer blocks the pop-up slider 63, and then the lifting mechanism 2 is no longer driven. The base 3 moves downward under its own weight and causes the clamp 4 to move downward, so as to Figure 7 As shown for reference, the pop-up slider 63 moves downward along the side of the arc-shaped stopper 52, and the hook tongue 6 squeezes the elastic member 7 so that the base 3 and the heat storage chamber 1 are fixed;

[0044] by Figure 8 The figure is used as a reference. When the base 3 and the heat storage chamber 1 need to be released, the lifting mechanism 2 is continued to be used to move the base 3 upward. The base 3 drives the clamp 4 to move upward, and the clamp 4 disengages from the lower bent portion 62. Then the clamp 4 continues to move upward and contacts the upper hook portion 61, driving the hook tongue 6 to move vertically upward, and the pop-up slider 63 moves upward along the side of the arc-shaped stopper 52 until it slides out of the arc-shaped stopper 52. At this time, the pop-up slider 63 is located in the deep groove 51, and the spring on the pop-up slider 63 is released. Then the lifting mechanism 2 is used again to move the base 3 downward. Since the base 3 is supported by the lifting mechanism 2, the pop-up slider 63 moves downward at a relatively slow speed. During the downward movement of the pop-up slider 63, it is blocked by the top side of the arc-shaped stopper 52 and guided by the top side of the arc-shaped stopper 52, so that the pop-up slider 63 slides to the rightmost end of the horizontal groove of the T-slot 5.

[0045] As another embodiment further provided by the present invention, two ends of the elastic member 7 are fixedly disposed on the second end of the hook tongue 6 and the heat storage chamber 1 respectively, and a bending portion 71 abutting against the groove is disposed on the elastic member 7.

[0046] Specifically, Figure 5As shown in the figure for reference, the hook tongue 6 is in an inclined state in the initial state. At this time, the second end of the hook tongue 6 is located at the rightmost end of the transverse groove of the T-slot 5, the elastic member 7 is stretched, and the bent portion 71 is in a fully expanded state, and then the second end of the hook tongue 6 slides to the middle of the deep groove 51, as shown in FIG. Figure 6 In the state shown, the clamp 4 no longer pushes the upper hook portion 61 upward, and the hook tongue 6 does not move under the support of the elastic member 7, the bending portion 71 bends, and then the hook tongue 6 moves downward, as shown in FIG. Figure 7 In the state shown, the elastic member 7 squeezes the elastic member 7, and makes the groove face the bent portion 71 of the elastic member 7, and the bent portion 71 enters the groove so that the base 3 and the heat storage chamber 1 are clamped, and when the hook tongue 6 is driven to move upward again, the elastic member 7 is stretched, and the bent portion 71 is pulled out of the groove, and the bent portion 71 is fully unfolded again to disengage from the groove, and staggered with the groove as the groove moves upward, and the elastic member 7 no longer clamps the base 3, as shown in FIG. Figure 8 In the state shown, the second end of the hook tongue 6 then slides back to the rightmost end of the transverse groove of the T-slot 5 and stretches the elastic member 7.

[0047] As another embodiment further provided by the present invention, a rubber ring 8 for sealing the connection between the base 3 and the heat storage chamber 1 is provided on the elastic member 7, and an exhaust valve 81 is provided on the elastic member 7.

[0048] Specifically, after the base 3 is fastened to the heat storage chamber 1, a sealed environment is formed inside the rubber ring 8. As the temperature inside the heat storage chamber 1 increases, the temperature of the rubber ring 8 also increases. The internal air expands, driving the rubber ring 8 to expand, thereby further squeezing the elastic member 7 into the groove. At the same time, the expanded rubber ring 8 blocks the gap between the base 3 and the heat storage chamber 1 to prevent internal gas from leaking out. When the base 3 needs to be disassembled, the exhaust valve 81 must first be opened to discharge the air inside the rubber ring 8 to prevent the rubber ring 8 from continuing to press the elastic member 7.

[0049] Working principle: A rotating mechanism is provided on the base 3 to rotate the heat storage ceramic layer. When the heat storage ceramic needs to be replaced, a new heat storage ceramic filler is installed on the base 3, driving the base 3 to move vertically upward, and the clamp 4 moves accordingly and reaches the heat storage chamber 1. The clamp 4 first conflicts with the inclined hook tongue 6 in the initial state. Since the upper hook portion 61 extends out of the inner wall of the heat storage chamber 1 in the initial state, the hook portion 61 and the clamp 4 form a pick-and-drop fit to enable the hook tongue 6 to move. The clamp 4 is blocked by the upper hook portion 61 during the upward movement. Figure 5 and Figure 6As shown in the figure for reference, when the upper hook portion 61 of the hook tongue 6 is driven upward by the clamp 4, the pop-up slider 63 of the second end of the hook tongue 6 is pulled to slide from the right end to the left end of the T-slot 5. At this time, the hook tongue 6 changes from an inclined state to a vertical state, and the lower bent portion 62 is located directly below the clamp 4, and finally stays in the middle of the deep groove 51 of the T-slot 5. Since the setting of the arc-shaped stopper 52 blocks the pop-up slider 63, the pop-up slider 63 shrinks a distance until it intersects with the side of the arc-shaped stopper 52. At this time, the arc-shaped stopper 52 no longer blocks the pop-up slider 63, and then the lifting mechanism 2 is no longer driven, and the base 3 moves downward under its own weight and makes The clamping member 4 moves downward, and after the clamping member 4 moves downward a certain distance, it presses against the lower bent portion 62, so that the pop-up slider 63 of the hook tongue 6 presses the elastic member 7 downward along the T-slot 5, and makes the groove face the bent portion 71 of the elastic member 7, and the bent portion 71 enters the groove so that the base 3 and the heat storage chamber 1 are clamped, and a sealed environment is formed in the rubber ring 8. As the temperature inside the heat storage chamber 1 increases, the temperature of the rubber ring 8 also increases, and the internal air expands, driving the rubber ring 8 to expand, thereby further squeezing the elastic member 7 into the groove, and at the same time, the expanded rubber ring 8 blocks the gap between the base 3 and the heat storage chamber 1 to prevent the internal gas from leaking out;

[0050] by Figure 8 The figure is used as a reference. When the base 3 and the heat storage chamber 1 need to be released, the exhaust valve 81 must be opened first to discharge the air inside the rubber ring 8 to prevent the rubber ring 8 from continuing to press the elastic member 7. The lifting mechanism 2 is continued to be used to move the base 3 upward. The base 3 drives the clamping member 4 to move upward, and the clamping member 4 is separated from the lower bent portion 62. Then the clamping member 4 continues to move upward and contacts the upper hook portion 61, driving the hook tongue 6 to move vertically upward, and the pop-up slider 63 moves upward along the side of the arc-shaped stopper 52 until it slides out of the arc-shaped stopper 52. At this time, the pop-up slider 63 is located in the deep groove 51, and the spring on the pop-up slider 63 is released. Then the lifting mechanism 2 is used again to move the base 3 downward. Since the base 3 is supported by the lifting mechanism 2, the pop-up slider 63 moves downward at a relatively slow speed. During the downward movement of the pop-up slider 63, it is blocked by the top side of the arc-shaped stopper 52 and guided by the top side of the arc-shaped stopper 52, so that the pop-up slider 63 slides to the rightmost end of the horizontal groove of the T-slot 5, and the hook tongue 6 returns to its initial state.

[0051] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
