Description

Technical Field

[0001] The utility model relates to the technical field of calcining furnaces, and particularly relates to a calcining furnace with a protection structure. Background Art

[0002] According to the application number "CN202322342533.5", for the calcining furnace with a protection structure, the inner partition layer can inhibit the diffusion of heat inside the calcining furnace to the outside world, and the vacuum layer further isolates the heat inside the calcining furnace to avoid potential safety hazards caused by heat overflow, playing a protective role. The connecting device is located on the right side of the sealing device and the two are horizontally positioned, facilitating the movement of the sealing door into the sealing device, strengthening the tightness between the two, and preventing heat from overflowing. The sliding connection between the convex block and the first connecting plate can quickly move the sealing door into the sealing device, reducing heat overflow. The first connecting plate and the second connecting plate are connected by a hinge connection. After the sealing door moves into the sealing device, the hinge connection between the first connecting plate and the second connecting plate can accurately align the sealing ring with the sealing layer and the inner partition door with the first partition door layer, strengthening the tightness and reducing heat overflow. For the calcining furnace with a protection structure, by rotating the rotating handle, the inner partition door can be driven to rotate, facilitating the threaded connection between the inner partition door and the first partition door layer. The first partition door layer is provided with a first thread, and the inner partition door is provided with a second thread. After the inner partition door fits with the first partition door layer, by rotating the rotating handle, the inner partition door and the first partition door layer are threadedly connected to strengthen the tightness and further prevent heat from overflowing.

[0003] The inventor found the following problems in the prior art that have not been well solved during the implementation of this solution:

[0004] 1. After the second partition door cover is placed on the sealing layer, there is no limiting mechanism, resulting in insufficiently tight connection between the two after covering, and unable to achieve a good sealing and heat preservation effect;

[0005] 2. Although the inner partition door can be threadedly connected with the first thread through the second thread, when the second rotating shaft rotates, if the outer wall of the rotating shaft does not contact the inner wall of the hole of the sealing ring, there will be a gap between the top of the inner partition door and the bottom of the sealing ring after the inner partition door is threadedly connected. Coupled with the fact that the second partition door cannot be tightly covered, heat loss will still occur. If the outer wall of the second rotating shaft contacts the inner wall of the sealing ring, the rotation of the rotating shaft will cause the sealing ring to have a distorted surface or be damaged by friction. Summary of the Utility Model

[0006] The main purpose of the utility model is to provide a calcining furnace with a protection structure, which can effectively solve the problems in the background art.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A calciner with a protective structure, comprising a furnace body. An internal thread ring is provided at the top end of the inner wall of the furnace body. One side of the outer part of the top end of the furnace body is fixed with a rotating seat. A rotating plate is rotatably connected to the top of the rotating seat. Chutes are respectively dug on the inner walls of both sides of the top of the rotating plate. A slider is arranged inside the rotating plate. Two connecting rods are fixed to one side of the slider. An outer cover plate is fixed to the end of the connecting rod away from the slider. A sealing gasket is bonded to the bottom of the outer cover plate. A sealing insertion pad is bonded to the bottom of the sealing gasket. An external thread plug block is arranged below the sealing insertion pad. Through holes are respectively dug at the central positions of the outer cover plate, the sealing gasket, and the sealing insertion pad. An internal thread cylinder is inserted between the through holes. The outer wall of the top end of the internal thread cylinder is welded to the inner wall of the through hole at the position of the outer cover plate. A threaded rod is in threaded connection with the internal thread cylinder. An internal thread pressing block is in threaded connection with the outer wall of the threaded rod at the position above the outer cover plate.

[0009] Preferably, the bottom end of the threaded rod passing through the internal thread cylinder is fixedly connected to the top of the external thread plug block.

[0010] Preferably, the bottom of the internal thread pressing block touches the top of the outer cover plate. Handles are respectively arranged at the top of the internal thread pressing block and the top of the threaded rod.

[0011] Preferably, the outer wall of the internal thread cylinder is respectively bonded to the inner walls of the sealing gasket and the sealing insertion pad at the positions of the through holes.

[0012] Preferably, both ends of the slider are respectively slidably connected inside the chute.

[0013] Preferably, the bottom of the sealing gasket at the outer side position of the sealing insertion pad touches the top of the furnace body. The sealing insertion pad is inserted above the internal thread ring at the top inside the furnace body. The outer wall of the sealing insertion pad touches the inner wall of the top end of the furnace body. The external thread plug block is inserted into the internal thread ring and is in threaded connection with its inner wall.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The rotating plate can be rotated through the rotating seat, so that the outer cover plate changes from a vertical state to a horizontal state. The slider connected to the outer cover plate by the connecting rod slides vertically in the chute, so that the sealing gasket is pressed on the top of the furnace body, and the sealing insertion pad is inserted above the internal thread ring at the top inside the furnace body. By rotating the internal thread pressing block on the threaded rod, the bottom of the internal thread pressing block can be pressed down on the outer cover plate. When the external thread plug block is in threaded connection with the internal thread ring, the pressing of the internal thread pressing block on the outer cover plate can make the outer cover plate stably drive the sealing gasket to press on the top of the furnace body, ensuring the stability of the connection and avoiding heat loss.

[0016] 2. The threaded rod is welded in the through hole of the outer cover plate and adhered in the through holes of the sealing gasket and the sealing plug gasket, thus being connected into an integral body. When the threaded rod rotates to drive the external thread plug to be threadedly connected with the internal thread ring, the internal thread cylinder is welded to the through hole on the outer cover plate to maintain stability when the threaded rod rotates, avoiding deformation or damage to the sealing gasket and the sealing plug gasket. At the same time, it also prevents the temperature from escaping through the gap between the through hole and the threaded rod, increasing the protection performance.

[0022] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-4As shown in the figure, a calciner with a protective structure includes a furnace body 1. At the top inner wall of the furnace body 1, there is an internal thread ring 101. On one side of the outer part of the top of the furnace body 1, a rotating seat 3 is fixed. At the top of the rotating seat 3, a rotating plate 4 is rotatably connected. On both inner walls of the top of the rotating plate 4, chutes 5 are drilled. Inside the rotating plate 4, there is a slider 6. On one side of the slider 6, two connecting rods 7 are fixed. At the end of the connecting rod 7 away from the slider 6, an outer cover plate 2 is fixed. At the bottom of the outer cover plate 2, a sealing gasket 8 is adhesively bonded. At the bottom of the sealing gasket 8, a sealing plug 9 is adhesively bonded. Below the sealing plug 9, there is an external thread plug 10. Through holes 11 are drilled at the central positions of the outer cover plate 2, the sealing gasket 8, and the sealing plug 9. An internal thread cylinder 12 is inserted between the through holes 11. The outer wall of the top end of the internal thread cylinder 12 is welded to the inner wall of the through hole 11 at the position of the outer cover plate 2. The internal thread cylinder 12 is internally threaded with a threaded rod 13. On the outer wall of the threaded rod 13 above the outer cover plate 2, an internal thread pressing block 14 is threaded.

[0024] Specifically, one end of the threaded rod 13 passing through the bottom of the internal thread cylinder 12 is fixed to the top of the external thread plug 10. The rotation of the threaded rod 13 facilitates driving the external thread plug 10 to be threadedly connected with the internal thread ring 101.

[0025] Specifically, the bottom of the internal thread pressing block 14 touches the top of the outer cover plate 2. Handles 15 are provided at the top of the internal thread pressing block 14 and the top of the threaded rod 13, so that the outer cover plate 2 can be stably covered on the top of the furnace body 1.

[0026] Specifically, the outer wall of the internal thread cylinder 12 is adhesively bonded to the inner walls of the sealing gasket 8 and the sealing plug 9 at the positions of the through holes 11.

[0027] Specifically, both ends of the slider 6 are slidably connected inside the chutes 5, so that the outer cover plate 2 can descend vertically, enabling the sealing plug 9 to be inserted into the furnace body 1 and the sealing gasket 8 to touch the furnace body 1.

[0028] Specifically, the bottom of the sealing gasket 8 at the outer side position of the sealing plug 9 touches the top of the furnace body 1. The sealing plug 9 is inserted above the internal thread ring 101 at the inner top of the furnace body 1. The outer wall of the sealing plug 9 touches the inner wall of the top end of the furnace body 1. The external thread plug 10 is inserted into the internal thread ring 101 and is threadedly connected to its inner wall, thus increasing the heat preservation performance.

[0029] Working principle: The rotating plate 4 can rotate through the rotating seat 3, so that the outer cover plate 2 changes from a vertical state to a horizontal state. The slider 6 connected to the outer cover plate 2 through the connecting rod 7 slides in the chute 5 to vertically descend, so that the sealing gasket 8 presses on the top of the furnace body 1, and the sealing plug gasket 9 is inserted above the internal thread ring 101 inside the top end of the furnace body 1. By rotating the internal thread pressing block 14 on the threaded rod 13, the bottom of it can press on the outer cover plate 2 to descend. When the external thread plug 10 is threadedly connected to the internal thread ring 101, the pressing of the internal thread pressing block 14 on the outer cover plate 2 can make the outer cover plate 2 stably drive the sealing gasket 8 to press on the top of the furnace body 1, ensuring the stability of the connection and avoiding temperature loss. The threaded rod 13 is welded in the through hole 11 of the outer cover plate 2 and adhered in the through holes 11 of the sealing gasket 8 and the sealing plug gasket 9, so as to be connected into one body. When the threaded rod 13 rotates to drive the external thread plug 10 to be threadedly connected to the internal thread ring 101, the internal thread cylinder 12 maintains stability when the threaded rod 13 rotates through welding with the through hole 11 on the outer cover plate 2, avoiding deformation or damage of the sealing gasket 8 and the sealing plug gasket 9, and at the same time preventing the temperature from leaking through the gap between the through hole 11 and the threaded rod 13, increasing the protection performance.
