Description

Technical Field

[0001] This utility model belongs to the technical field of rotary kiln doors, specifically a new type of labor-saving rotary kiln door. Background Technology

[0002] Rotary kilns are core thermal equipment widely used in industries such as building materials, metallurgy, chemicals, and environmental protection. Their main body is a slightly inclined cylindrical shell that can rotate slowly. Rotary kilns have advantages such as large production capacity, strong adaptability, stable operation, and easy automation control. They are the core equipment for achieving high-temperature heat treatment of materials in many industrial production processes.

[0003] The rotary kiln door is installed at the kiln head or tail to seal the kiln body, prevent outside air from entering, and prevent the leakage of high-temperature gas inside the kiln. The existing rotary kiln door structure is generally a lower track sliding structure. Due to the unidirectional movement of the kiln door when opening and closing, a certain gap is always maintained between the kiln door and the kiln head cover, making sealing difficult, especially at the lower track area. Furthermore, the sliding structure makes opening and closing the kiln door very laborious, requiring multiple operators to work together, which is not only time-consuming and laborious but also affects the opening and closing efficiency. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a novel labor-saving rotary kiln door, which has the advantages of being labor-saving and having a good sealing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel labor-saving rotary kiln door, installed in a wall, with two longitudinal I-beams fixedly installed at the top of the front of the wall. A first hand-operated monorail trolley is movably installed inside each of the two longitudinal I-beams. A first hand-operated chain is movably installed inside the first hand-operated monorail trolley. A connecting plate is movably sleeved at the bottom of the first hand-operated monorail trolley. There are two connecting plates. A transverse I-beam is fixedly connected to the bottom of each of the two connecting plates. A movable monorail trolley and a second hand-operated monorail trolley are movably installed inside the transverse I-beams. A second hand-operated chain is movably installed inside the second hand-operated monorail trolley. A connecting block is movably sleeved at the bottom of both the movable monorail trolley and the second hand-operated monorail trolley. A kiln door is fixedly connected to the bottom of the connecting block. There are two kiln doors. Sealing rock wool is movably connected to the back of each of the two kiln doors. A kiln head cover is fixedly connected to the back of the sealing rock wool. The back of the kiln head cover is fixedly connected to the front of the wall.

[0006] As a preferred embodiment of this utility model, a fixing block and a first U-shaped plate are respectively fixedly installed on the front of the two kiln doors. A rotating shaft is movably sleeved inside the fixing block, and a bolt is fixedly installed on the right side of the rotating shaft. The outer surface of the bolt is movably connected to the inner surface of the first U-shaped plate.

[0007] As a preferred embodiment of this utility model, a washer is movably fitted on the right side of the outer surface of the bolt, the outer surface of the washer is movably connected to the outer surface of the first U-shaped plate, and a nut is threadedly fitted on the right side of the outer surface of the bolt.

[0008] As a preferred embodiment of this invention, sealing rings are fixedly installed inside both kiln doors, and second U-shaped plates are fixedly installed on the outer sides of both kiln doors.

[0009] As a preferred embodiment of this utility model, the kiln head cover has limit grooves on both the left and right sides, and limit blocks are movably installed inside the limit grooves. A side plate is fixedly connected to the outside of the limit block, and the outer surface of the side plate is movably connected to the outer surface of the kiln head cover. A rotating rod is hinged inside the side plate, and the outer surface of the rotating rod is movably connected to the inner surface of the second U-shaped plate. A round rod is fixedly connected to the front end of the rotating rod.

[0010] As a preferred embodiment of this utility model, mounting plates are fixedly installed on both the left and right sides of the kiln head hood, and a double threaded rod is movably sleeved between the mounting plates. A rotating block is fixedly sleeved on the middle of the outer surface of the double threaded rod.

[0011] As a preferred embodiment of this utility model, both the upper and lower sides of the outer surface of the double-threaded rod are threaded with movable blocks, and the rear end of the movable block is hinged with a hinge rod, the other end of which is hinged to the front of the side plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a longitudinal H-beam, a first hand-operated monorail trolley, a transverse H-beam, and a second hand-operated monorail trolley, allows the operator to open the kiln door by pulling the second hand-operated chain, causing the second hand-operated monorail trolley to move outward along the surface of the transverse H-beam. This, in turn, moves the kiln door through the connecting block, separating the two kiln doors. Then, by pulling the first hand-operated chain, the first hand-operated monorail trolley moves along the surface of the longitudinal H-beam, causing the transverse H-beam to move forward through the connecting plate. The transverse H-beam, through the movable monorail trolley and the second hand-operated monorail trolley, moves the kiln door forward. This allows the kiln door to move forward, backward, left, and right during opening and closing, facilitating operation and increasing the freedom of movement of the kiln door, enabling it to fit snugly against the kiln head cover.

[0014] 2. This utility model, by setting a second U-shaped plate, a side plate, a round rod, and a hinge rod, when sealing between the kiln door and the kiln head cover, rotates the rotating rod so that it enters the interior of the second U-shaped plate. Then, by rotating the rotating block, the double threaded rod drives the two moving blocks to move in opposite directions, thereby causing the hinge rod to push the side plate to move backward, so that the round rod contacts the front of the second U-shaped plate. In turn, the second U-shaped plate drives the kiln door to move backward, so that the kiln door, sealing rock wool, and kiln head cover can fit together tightly, thereby improving the sealing effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 8 As shown, this utility model provides a novel labor-saving rotary kiln door, installed on a wall 1. Two longitudinal I-beams 2 are fixedly installed at the top of the front of the wall 1. A first manual monorail trolley 3 is movably installed inside each of the two longitudinal I-beams 2. A first manual chain 4 is movably installed inside the first manual monorail trolley 3. Two connecting plates 5 are movably connected to the bottom of each of the two connecting plates 5. A transverse I-beam 6 is fixedly connected to the bottom of each transverse I-beam 6. The interior of the device is equipped with a movable monorail trolley 7 and a second manual monorail trolley 8. The second manual monorail trolley 8 is equipped with a second manual chain 9. The bottom of both the movable monorail trolley 7 and the manual monorail trolley 8 is movably fitted with a connecting block 10. The bottom of the connecting block 10 is fixedly connected to a kiln door 11. There are two kiln doors 11. The back of both kiln doors 11 is movably connected with sealing rock wool 12. The back of the sealing rock wool 12 is fixedly connected with a kiln head cover 13. The back of the kiln head cover 13 is fixedly connected to the front of the wall 1.

[0026] When the operator needs to open the kiln door 11, he can pull the second manual chain 9 to move the second manual monorail trolley 8 outward along the surface of the transverse I-beam 6, thereby moving the kiln door 11 through the connecting block 10 and separating the two kiln doors 11. The operator can also pull the first manual chain 4 to move the first manual monorail trolley 3 along the surface of the longitudinal I-beam 2, thereby moving the transverse I-beam 6 forward through the connecting plate 5. The transverse I-beam 6 then moves the kiln door 11 forward through the movable monorail trolley 7 and the second manual monorail trolley 8, thus enabling the kiln door 11 to move forward, backward, left, and right when opening and closing.

[0027] Among them, a fixing block 14 and a first U-shaped plate 15 are fixedly installed on the front of the two kiln doors 11 respectively. A rotating shaft 16 is movably connected inside the fixing block 14. A bolt 17 is fixedly installed on the right side of the rotating shaft 16. The outer surface of the bolt 17 is movably connected to the inner surface of the first U-shaped plate 15.

[0028] The operator can rotate the bolt 17 around the pivot 16 to disengage the bolt 17 from the interior of the first U-shaped plate 15.

[0029] Among them, a washer 18 is movably sleeved on the right side of the outer surface of the bolt 17, and the outer surface of the washer 18 is movably connected to the outer surface of the first U-shaped plate 15. A nut 19 is threadedly sleeved on the right side of the outer surface of the bolt 17.

[0030] The operator can rotate the nut 19 to move it to the left, thereby causing the washer 18 to fit tightly against the right side of the first U-shaped plate 15, so that the two kiln doors 11 can be closed and connected together.

[0031] Both kiln doors 11 are equipped with sealing rings 20 inside, and both kiln doors 11 are equipped with second U-shaped plates 21 on the outside.

[0032] By setting the sealing ring 20, the sealing ring 20 can play a sealing role and prevent air leakage.

[0033] The kiln head cover 13 has limit grooves 22 on both the left and right sides. Limit blocks 23 are movably installed inside the limit grooves 22. Side plates 24 are fixedly connected to the outside of the limit blocks 23. The outer surface of the side plates 24 is movably connected to the outer surface of the kiln head cover 13. A rotating rod 25 is hinged inside the side plates 24. The outer surface of the rotating rod 25 is movably connected to the inner surface of the second U-shaped plate 21. A round rod 26 is fixedly connected to the front end of the rotating rod 25.

[0034] When the side plate 24 moves backward under the limiting action of the limiting block 23 and the limiting groove 22, the round rod 26 will contact the front of the second U-shaped plate 21, thereby driving the kiln door 11 to move towards the kiln head cover 13 through the second U-shaped plate 21, so that the kiln door 11, the sealing rock wool 12 and the kiln head cover 13 can fit together tightly to avoid air leakage.

[0035] Among them, mounting plates 27 are fixedly installed on both the left and right sides of the kiln head cover 13, and double threaded rods 28 are movably sleeved between the mounting plates 27. A rotating block 29 is fixedly sleeved on the middle of the outer surface of the double threaded rods 28.

[0036] The operator can rotate the rotating block 29 to make the double threaded rod 28 rotate, and the threads on the upper and lower sides of the double threaded rod 28 are opposite in direction.

[0037] The double threaded rod 28 has a moving block 30 threadedly connected to both the upper and lower sides of its outer surface. The moving block 30 has a hinge rod 31 hinged to the rear end of its rear end. The other end of the hinge rod 31 is hinged to the front of the side plate 24.

[0038] When the rotating block 29 rotates, the double threaded rod 28 will cause the two moving blocks 30 to move towards or away from each other, thereby enabling the side plate 24 to move through the hinge rod 31.

[0039] Working principle and usage process of this utility model:

[0040] When opening the kiln door 11, the operator first rotates the nut 19, causing it to move to the right along the outer surface of the bolt 17. At this time, the operator rotates the bolt 17 around the pivot 16, causing the bolt 17 to disengage from the inside of the first U-shaped plate 15, thereby detaching the connection between the kiln door 11 and the nut 19. Then, the operator rotates the rotating block 29, causing the rotating block 29 to drive the double threaded rod 28 to rotate. The double threaded rod 28 will drive the two moving blocks 30 to move in opposite directions, causing the hinge rod 31 to pull the side plate 24 forward under the limiting action of the limiting block 23. At this time, the side plate 24 will drive the rotating rod 25 and the round rod 26 to move forward, causing the round rod 26 to disengage from the contact with the second U-shaped plate 21. Then, the operator rotates the rotating rod 25, causing it to disengage from the contact with the second U-shaped plate 21, thereby detaching the connection between the kiln door 11 and the kiln head cover 13, and allowing the kiln door 11 to be moved.

[0041] Then, the operator pulls the second hand chain 9, causing the second hand-pulled monorail trolley 8 to move outward along the surface of the transverse I-beam 6, thereby moving the kiln door 11 through the connecting block 10, thus separating the two kiln doors 11. Then, the first hand chain 4 is pulled, causing the first hand-pulled monorail trolley 3 to move forward along the surface of the longitudinal I-beam 2, thereby moving the transverse I-beam 6 forward through the connecting plate 5. The transverse I-beam 6 then moves the kiln door 11 forward through the movable monorail trolley 7 and the second hand-pulled monorail trolley 8, thus enabling the kiln door 11 to move forward, backward, left, and right when opening and closing, which is convenient for the operator.
