Description

Technical Field

[0001] This utility model relates to the field of annular roasting furnace technology, and in particular to an annular roasting furnace heat preservation device. Background Technology

[0002] In the graphite manufacturing process, the roasting process usually uses a ring roasting furnace. The ring roasting furnace is one of the main thermal equipment in the carbon production industry. In actual production, the surface temperature of the furnace cover in the high-temperature furnace chamber can reach more than 140°C, resulting in significant heat loss. Therefore, it is very important to do a good job of heat preservation in the ring roasting furnace, which is why a ring roasting furnace heat preservation device is used.

[0003] To this end, patent CN219083725U discloses a ring furnace calcining crucible device, belonging to the field of crucible calcining furnace technology. The ring furnace calcining crucible device includes a crucible; a cover plate disposed on the side end of the crucible; a stopper disposed on the lower end of the cover plate; and a slot disposed on the upper end of the crucible. The upper end of the stopper is fixedly connected to multiple fixing rods, and each fixing rod is slidably connected to a locking plate. The upper end of each locking plate is connected to a limiting rod, which is connected to the cover plate. The locking plates match the slots. By setting the locking plates on the fixing rods, after the stopper is matched with the crucible, the locking plates on the upper end of the stopper can be moved by the handle to match the locking plates with the slots, so that the crucible can have better stability and sealing when in use.

[0004] Although the ring furnace calcining crucible device mentioned above has better stability and sealing, it is extremely inconvenient to use because it is difficult to move and quick to open and close. Utility Model Content

[0005] The purpose of this invention is to provide a ring-type roasting furnace insulation device to solve the problem that existing ring-type roasting furnace insulation devices are inconvenient to move.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ring-type roasting furnace heat preservation device, including a base and a support;

[0007] A support is fixed to the top of the base, and a furnace body is provided at the top of the base below the support. An insulation structure is provided on the outer side of the bottom of the furnace body.

[0008] The top of the furnace body is provided with an end cover, and the outer side of the end cover is provided with a sealing structure;

[0009] The top of the support is provided with a movable structure, which includes an electric push rod, a sliding rod, a movable plate and a connecting seat. The electric push rod passes through the top of the support, and sliding rods pass through the interior of the support on both sides of the electric push rod. A movable plate is fixed to the bottom end of the electric push rod, and a connecting seat is fixed to the bottom end of the movable plate.

[0010] When using this device, the movable structure facilitates its opening and closing, thereby improving the convenience of use; the insulation structure facilitates its insulation function, thereby improving its applicability; and the sealing structure prevents leakage, thereby improving its stability during use.

[0011] Preferably, the slide rod and the support form a sliding structure, with the bottom end of the slide rod fixedly connected to the top end of the moving plate, and the bottom end of the connecting seat fixedly connected to the top end of the end cover. When the electric push rod drives the moving plate to move, the stability of the moving plate during movement is enhanced under the action of the slide rod. The moving plate drives the end cover to move through the connecting seat, thereby separating and fixing the end cover from the furnace body.

[0012] Preferably, the insulation structure includes a heat insulation cylinder, a heat insulation layer, and a refractory layer. The refractory layer is disposed on the outer side of the bottom of the furnace body, the heat insulation layer is fixed to the outer side of the refractory layer, and the heat insulation cylinder is fixed to the outer side of the heat insulation layer. The refractory layer is actually made of refractory fiber, which is lightweight, high-temperature resistant, and has good thermal stability. It can effectively reduce heat loss from the furnace body, improve energy utilization efficiency, prevent heat transfer from inside the furnace body to the outside, and protect the furnace body from high-temperature damage.

[0013] Preferably, the insulation layer is actually an aluminosilicate fiber blanket, and the refractory layer is actually refractory fiber. By using an aluminosilicate fiber blanket as the insulation layer, heat loss can be effectively reduced, thus significantly improving the furnace's insulation performance.

[0014] Preferably, the main view section of the end cover is T-shaped, and the end cover and the furnace body form a sliding structure.

[0015] Preferably, the sealing structure includes a thermal insulation layer, a carbon fiber felt, and a fire-resistant coating. The thermal insulation layer is fixed to the outer side of the top of the end cap, the carbon fiber felt is fixed to the outer side of the bottom of the end cap, and the fire-resistant coating is fixed to the outer side of the carbon fiber felt. The thermal insulation layer is actually a silicate composite layer, which has good thermal insulation performance, effectively reducing heat loss and maintaining temperature stability.

[0016] Preferably, the insulation layer is actually a silicate composite layer, and the outer side of the refractory coating is in contact with the inner side of the furnace body. With the help of carbon fiber felt, it has excellent heat insulation and heat preservation properties, which can reduce energy loss and improve heating efficiency. Under the action of the refractory coating, a dense protective layer is formed, which can effectively prevent erosion from the external environment.

[0017] The advantages of the ring-type roasting furnace heat preservation device provided by this utility model are as follows:

[0018] By incorporating a movable structure, when the electric push rod drives the movable plate to move, the stability of the movable plate during movement is enhanced under the action of the sliding rod. The movable plate drives the end cover to move through the connecting seat, so that the end cover is separated from and fixed to the furnace body, realizing the function of easy opening and closing of the device, thereby improving the convenience of using the ring-type roasting furnace heat preservation device.

[0019] By incorporating an insulation structure, and using refractory fibers as the refractory layer (which are lightweight, high-temperature resistant, and have good thermal stability), the heat loss of the furnace body can be effectively reduced, energy utilization efficiency can be improved, and heat inside the furnace body can be prevented from being transferred outward, protecting the furnace body from high-temperature damage. The insulation layer is actually an aluminosilicate fiber blanket, which can effectively reduce heat loss and improve the insulation performance of the furnace body. This makes the device easy to use for heat preservation, thereby improving the applicability of the ring-type roasting furnace insulation device in use.

[0020] By incorporating a sealed structure and using a silicate composite insulation layer, which provides excellent thermal insulation, effectively reducing heat loss and maintaining temperature stability, the device further enhances its thermal insulation and heat preservation properties. The addition of carbon fiber felt further reduces energy loss and improves heating efficiency. A dense protective layer is formed by the refractory coating, effectively preventing external environmental corrosion and ensuring leak-proof operation. This significantly improves the stability of the ring-type roasting furnace insulation device during use. Attached Figure Description
