Description

Technical Field

[0001] This utility model relates to the technical field of ring-type roasting furnaces, and in particular to a ring-type carbon roasting furnace. Background Technology

[0002] A ring-type calcining furnace is a thermal equipment consisting of several identical furnace chambers arranged in double rows, operating on a moving flame system to calcine and heat-treat pressed raw products. It is one of the main thermal equipment in the carbon production industry, characterized by high energy consumption and low heat utilization. Typically, it is built underground, with only the furnace cover exposed above ground. The furnace cover is composed of a steel frame and refractory materials. In actual production, the surface temperature of the furnace cover in the high-temperature chamber can reach over 140 degrees Celsius, resulting in significant heat loss. Therefore, ensuring proper insulation of the furnace cover is just as important as achieving overall energy conservation in the ring-type calcining furnace.

[0003] The existing Chinese utility model patent with application number CN201220009753.5 relates to a ring roasting furnace, including a furnace body, a material box, a fire channel, a scavenging device, a gas generator, and an exhaust device, which can achieve good sealing effect.

[0004] However, in actual use, the above-mentioned device has a low utilization rate of high-temperature flue gas and poor flow of high-temperature flue gas inside the equipment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a ring-type carbon roasting furnace that uses a roasting device to roast carbon materials, uses a combustion device to provide high-temperature flames and combustibles, and uses the roasting device itself to roast different areas to ensure uniform heat distribution. A protective device provides rapid sealing to reduce the leakage of high-temperature gases, increase the efficiency of heat utilization, and improve the practicality of the device.

[0006] This utility model discloses a ring-type carbon roasting furnace, comprising a roasting device, a combustion device, and a protective device. The combustion device is installed on the roasting device, and the protective device is installed on the roasting device. The roasting device roasts carbon materials, the combustion device provides high-temperature flames and combustibles, and the roasting device itself is used to roast different areas, resulting in uniform heat distribution. The protective device provides rapid sealing, reduces the leakage of high-temperature gases, increases the efficiency of heat utilization, and improves the practicality of the device.

[0007] Preferably, the roasting apparatus includes a furnace body, roasting chambers, fire channels, ventilation holes, a material support platform, fire channel sealing covers, and chamber sealing covers. Two rows of roasting chambers are arranged inside the furnace body, with two sets of fire channels between each row. Ventilation holes are provided on the sides of the fire channels. Ventilation holes are also provided between adjacent sets of roasting chambers at both ends of each row. A material support platform is provided at the bottom of each set of roasting chambers, with exhaust holes at the bottom of the material support platform. A fire channel sealing cover is provided above the fire channels, and a chamber sealing cover is provided above each set of roasting chambers. The chamber sealing cover seals each set of roasting chambers, reducing heat loss. The fire channel sealing cover seals the fire channels. The material support platform supports the material. The ventilation holes allow high-temperature gas to flow between the roasting chambers. The fire channels, in conjunction with the combustion device, provide heating, thus improving the practicality of the apparatus.

[0008] Preferably, the combustion device includes a lifting frame, a baffle plate, a blower, and a fuel pipe valve. The baffle plate is installed on the lower end face of the lifting frame, and the blower and fuel pipe valve are installed on the upper end face of the lifting frame. The baffle plate has an air outlet and a fuel injection outlet on its lower end face. The fuel injection outlet is connected to the fuel pipe valve. The output end of the blower is connected to the air outlet of the baffle plate. An igniter is installed at the bottom of the baffle plate. When heating, the baffle plate is placed into the desired combustion chamber. Then, external fuel is output from the baffle plate into the combustion chamber through the fuel pipe valve. At the same time, the blower is turned on to send outside air into the combustion chamber. Together with the igniter at the bottom of the baffle plate, the fuel is ignited and heated, which improves the practicality of the device.

[0009] Preferably, it also includes hooks and lifting hooks. A set of hooks is hung on the left and right sides of the upper end face of the lifting frame, and the lifting hooks are connected to the two sets of hooks by two sets of steel wire ropes. The external door machine is connected to the hooks and hooks to control the movement of the combustion device to different fire channels for heating, so that the materials are heated evenly and the practicality of the device is improved.

[0010] Preferably, it also includes a chamfer. The top edge of the fire channel is chamfered, and the upper part of the insert plate is chamfered to match the chamfer on the top edge of the fire channel. The chamfer on the top surface of the fire channel facilitates the insertion of the insert plate into the fire channel, and the chamfer on the insert plate increases the sealing of the upper surface of the fire channel during ignition and heating, reduces heat loss, and improves the practicality of the device.

[0011] Preferably, the protective device includes a rotating shaft, a quick-release baffle, a rotating wheel, and a stainless steel counterweight. The rotating shaft is installed on the top side of the fire channel, and the quick-release baffle is fitted onto the rotating shaft. One end of the rotating shaft extends to the outer side of the furnace body and connects to the rotating wheel. The stainless steel counterweight is connected to the side of the rotating wheel by a steel wire rope. In its natural state, the stainless steel counterweight pulls the rotating wheel, causing the quick-release baffle on the rotating shaft to seal the upper end of the fire channel. When the insert plate is inserted into the fire channel, the lower part of the insert plate pushes the quick-release baffle down, causing the stainless steel counterweight to rise. When the insert plate is pulled out, the stainless steel counterweight falls due to gravity, which in turn drives the quick-release baffle to quickly seal the upper end of the fire channel, reducing heat loss during the insertion and removal of the insert plate and improving the practicality of the device.

[0012] Preferably, it also includes electromagnets. Multiple sets of electromagnets are installed on the side of the furnace body via brackets. The multiple sets of electromagnets are located under multiple sets of stainless steel counterweights. When the stainless steel counterweights fall to the bottom, the electromagnets attract the bottom of the stainless steel counterweights, thereby increasing the pulling force on the rotating wheel, reducing the gap between the fast baffle and the upper surface of the fire channel, and improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: carbon materials are roasted by a roasting device, high-temperature flames and combustibles are provided by a combustion device, and different areas are roasted by the structure of the roasting device itself, so that the heat is evenly distributed. The protective device provides rapid sealing, reduces the leakage of high-temperature gas, increases the efficiency of heat use, and improves the practicality of the device.
