[0036] As attached Figure 1 -Attached Figure 8 As shown, the utility model provides a kiln door, including a door support 8, a door panel 11, a door panel pressing mechanism and a door panel moving mechanism;

[0037] The furnace door support 8 includes two side plates 81 arranged opposite to each other, a first accommodating cavity 82 is formed between the two side plates 81, and openings 83 are arranged at corresponding positions of the two side plates 81. When the door is in an open state, the material enters or leaves the chamber 10 of the kiln through the two openings 83;

[0038] The door panel 11 is arranged in the first accommodating cavity 82, and the door panel moving mechanism is used to drive the door panel 11 to cover or leave the opening 83. When the door panel 11 covers the opening 83, the door is in a closed state, and the material cannot enter or leave the chamber 10 of the kiln through the two openings 83. When the door panel 11 leaves the opening 83, the door is in an open state.

[0039] The door panel pressing mechanism is used to press the door panel 11 against one of the side panels 81 when the door panel 11 covers the opening 83, and the side panel 81 is fixedly connected to the chamber 10 of the kiln. At this time, the door panel 11 combined with the side panel 81 can close the opening of the chamber 10 of the kiln.

[0040] The kiln door provided by the utility model can close the opening of the kiln chamber 10 by pressing the door panel 11 onto the side panel 81 connected to the chamber 10 of the kiln, and can provide a stable pressing force to ensure the sealing effect. In addition, the conventional high-sealing matching structure can be omitted, and the sealing mechanism can be simplified on the basis of ensuring the sealing of the door. Moreover, the opening direction of the door panel 11 in the door is perpendicular to the direction of the opening of the chamber 10. In the process of opening and closing the opening, the space outside the opening will not be occupied, which is convenient for materials to enter or leave the chamber 10. In addition, both side panels 81 can be used to connect the chamber 10, and the connection between the two chambers 10 can be realized at an ultra-short distance, and the two connected chambers 10 also have a door structure that can be opened and closed. In addition, the kiln door is separated from the chamber 10 by connecting with the chamber 10 through the side panel 81, which is convenient for installation, maintenance and replacement.

[0041] In one embodiment, the door panel pressing mechanism includes a plurality of first linear drive mechanisms 7 disposed on the other side panel 81. The first linear drive mechanism 7 may be a cylinder, a hydraulic cylinder or an electric cylinder. The cylinder body thereof is disposed on the side of the side panel 81 away from the first accommodation chamber 82. The output piston thereof extends through the plate body of the side panel 81 into the first accommodation chamber 82. The piston extends to press the door panel 11 against the other side panel 81.

[0042] Several first linear drive mechanisms 7 are arranged outside the opening 83 of the side panel 81, so that the output end of the first linear drive mechanism 7 abuts against the door panel 11, and the abutting position of the door panel 11 abuts against the side panel 81. This can prevent the first linear drive mechanism 7 from acting on the door panel 11 within the range of the opening 83, causing the door panel 11 to be subjected to shear force, causing the door panel 11 to deform, thereby increasing the clamping force of the first linear drive mechanism 7 on the door panel 11 while avoiding deformation of the door panel 11.

[0043] In one of the embodiments, a plurality of first linear drive mechanisms 7 are evenly arranged outside the opening 83 of the side panel 81 , thereby improving the uniformity of compression at various positions of the door panel 11 and improving the uniformity of sealing of the door panel 11 .

[0044] In one of the embodiments, a side panel 81 that cooperates with the door panel 11 is provided with a circle of first sealing ring 20 on the outside of the opening 83. At this time, when the door panel 11 is pressed and fitted with the side panel 81, the door panel 11 is pressed tightly against the circle of first sealing ring 20, which can greatly improve the sealing effect of the door panel 11 on the opening 83.

[0045] In one embodiment, the door panel moving mechanism is arranged above the furnace door bracket 8, and the door panel moving mechanism drives the door panel 11 to rise and fall in the first accommodating cavity 82. At this time, the door panel 11 moves upward to leave the opening 83, and moves downward to cover the opening 83. The door panel moving mechanism can use the gravity of the door panel 11 to rise and fall, thereby reducing the burden on the door panel moving mechanism.

[0046] In one embodiment, the door panel moving mechanism includes a second linear drive mechanism 1, which can be a cylinder, a hydraulic cylinder or an electric cylinder, and the door panel 11 is flexibly connected to the output end of the second linear drive mechanism 1, that is, the door panel 11 can also move relative to the output end of the second linear drive mechanism 1, and can move flexibly when the door panel clamping mechanism drives the door panel 11 to be laterally close to one of the side panels 81. Specifically, the flexible connection can be a rope, and in other embodiments, the door panel moving mechanism can directly use a rope hoisting device, in which case the output end of the door panel moving mechanism is directly and flexibly connected to the door panel 11.

[0047] Reference Figure 5 In one preferred embodiment, the output end of the second linear drive mechanism 1 and the upper end of the door panel 11 are connected through a hinge plate 17, and the hinge plate 17 is respectively hinged to the output end of the second linear drive mechanism 1 and the door panel 11. In this embodiment, a flexible connection is formed between the door panel 11 and the output end of the second linear drive mechanism 1 through the hinge plate 17, which can ensure the structural strength and improve the structural stability. Preferably, the hinge plate 17 is respectively hinged to the output end of the second linear drive mechanism 1 and the door panel 11 through two pins 16, which is convenient for disassembly and assembly. Preferably, the hinge plate 17 is connected to the second linear drive mechanism 1 through an upper joint 19, which simplifies the connection difficulty between the second linear drive mechanism 1 and the hinge plate 17.

[0048] In one embodiment, a sealing plate 84 is disposed at the bottom and sidewalls of the first accommodating cavity 82, and an inlet and outlet 85 is disposed at the top of the first accommodating cavity 82;

[0049] The upper end of the furnace door bracket 8 is provided with a door panel accommodating bin 5, and a second sealed cavity 51 is provided in the door panel accommodating bin 5. The bottom of the second sealed cavity 51 is communicated with the inlet and outlet 85. In this embodiment, when both side plates 81 are connected with bins 10, the first accommodating cavity 82 and the second sealed cavity 51 form a sealed structure, and the gas in the bin 10 will not leak from the kiln bin door, which can ensure the sealing of the two bins 10 when the bin doors are opened or closed.

[0050] The second linear drive mechanism 1 is arranged on the furnace door bracket 8, and is used to drive the door panel 11 to switch between the first accommodating chamber 82 and the second sealing chamber 51. When the door is opened, the second linear drive mechanism 1 drives the door panel 11 to the second sealing chamber 51, and when the door is closed, the second linear drive mechanism 1 drives the door panel 11 to the first accommodating chamber 82. In this embodiment, when both side panels 81 are connected with the chamber 10, the sealed connection of the chamber 10 can be achieved. Preferably, the door panel accommodating chamber 5 is fixedly connected with the furnace door bracket 8 by bolts, and a second sealing gasket 6 is sandwiched between the door panel accommodating chamber 5 and the furnace door bracket 8, which facilitates the disassembly and assembly of the door panel accommodating chamber 5 and the furnace door bracket 8 and improves the sealing of the two. A mounting port is arranged on the top of the door panel accommodating chamber 5, and a cover plate 3 is connected to the mounting port by bolts, which facilitates the installation of the door panel 11. At this time, a first sealing gasket 4 is sandwiched between the cover plate 3 and the door panel accommodating chamber 5.

[0051] In one of the embodiments, the body of the second linear drive mechanism 1 is arranged on the top outer side of the door panel accommodating chamber 5, and the output end passes through the top of the door panel accommodating chamber 5 and extends into the second sealed cavity 51, so as to increase the moving stroke of the door panel and avoid the second linear drive mechanism 1 from being in a harsh environment. In this embodiment, the cylinder mouth of the second linear drive mechanism 1 is arranged downward, which saves upper space, shortens the guide rod length, makes installation simpler, and makes the mechanical structure more stable.

[0052] A sealing guide sleeve 2 is also provided on the outer side of the top of the door panel accommodating compartment 5. Preferably, the sealing guide sleeve 2 is arranged on the cover plate 3, and the sealing guide sleeve 2 is connected to the cover plate 3 by threads. A sliding hole 31 is provided on the top of the door panel accommodating compartment 5 at the sealing guide sleeve 2, that is, a sliding hole 31 is provided on the cover plate 3, and a guide rod 15 is slidably provided in the sealing guide sleeve 2 and the sliding hole 31, and the other end of the guide rod 15 is connected to the door panel 11, thereby improving the movement and guiding property of the door panel 11. Preferably, a sliding sleeve 14 is provided on the sliding hole 31, and the sliding sleeve 14 is fixed to the cover plate 3 by bolts, and a dust ring 12 and a second sealing ring 13 are provided between the sliding sleeve 14 and the cover plate 3. Preferably, the guide rod 15 is flexibly connected to the door panel 11, and more preferably, the guide rod 15 is connected to the door panel 11 through a hinge plate 17, and the two ends of the hinge plate 17 are respectively hinged to the guide rod 15 and the door panel 11. Preferably, the hinge plate 17 is connected to the guide rod 15 through a lower joint 18, which simplifies the difficulty of connecting the guide rod 15 and the hinge plate 17.

[0053] The utility model further provides a kiln, comprising a chamber 10 and at least one kiln chamber door arranged on the chamber 10 .

[0054] In one of the embodiments, one of the side panels 81 of the furnace door is fixedly connected to the chamber 10 by bolts, and a third sealing gasket 9 is sandwiched between the side panel 81 and the chamber 10 .

[0055] Taking the roller kiln as an example, and both ends of the roller kiln are provided with kiln doors, the specific working principle of the kiln is as follows:

[0056] Driven by the roller, the material enters the chamber 10, the piston rod of the second linear drive mechanism 1 descends, and the door panel 11 descends to the specified position. The piston rod of the first linear drive mechanism 7 extends to support the door panel 11, so that it presses the first sealing ring 20. The chamber 10 reaches a sealed state, and after being evacuated, a protective gas is introduced. The piston rod of the first linear drive mechanism 7 of the rear door retracts, and the piston rod of the second linear drive mechanism 1 rises, driving the door panel 11 to rise. The material leaves the chamber 10 under the action of the roller, and the door panel 11 of the rear door descends and presses the first sealing ring 20, and the door panel 11 of the front door rises, entering the next cycle.

[0057] The above is only an embodiment and does not limit the present invention in any way.
