Description

Technical Field

[0001] This utility model relates to the technical field of graphitization furnaces, and in particular to an energy-saving box furnace device for graphite anode materials. Background Technology

[0002] The graphitization box furnace technology uses the Atchison graphitization box furnace to prepare graphitized materials.

[0003] In the prior art, patent document CN210286762U discloses a graphitization box furnace, which consists of ten individual furnaces arranged in parallel. Each individual furnace includes a furnace body with heating function and a fume hood with exhaust function. The graphitization box furnace adopts a long furnace body constructed of refractory material, and is filled with low-sulfur calcined coke to form a conductive furnace core. There are heat-insulating materials on both sides of the furnace head. Conductive electrodes are set on the walls at both ends of the furnace head and connected to the power supply to form an electric circuit. When the circuit is connected, the furnace core heats up due to the resistance, so that the furnace core is graphitized by high-temperature heat treatment at a temperature of 2600-3000 degrees Celsius.

[0004] During use, it was discovered that the high-temperature flue gas generated by the above-mentioned furnace group contained particulate dust. The high-temperature flue gas and particulate dust were directly emitted into the outside world, causing environmental pollution. The environmental protection needs to be further improved. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an energy-saving box furnace device for graphite anode materials.

[0006] This utility model discloses an energy-saving box furnace for graphite anode materials, comprising a furnace body, a fume hood, and a flue pipe. The fume hood is installed at the top of the furnace body, and its output end is connected to the input end of the flue pipe. It also includes a dust suppression component, the output end of which is connected to the input end of the dust suppression component. The dust suppression component is used for dust separation in the flue gas. In use, the large amount of flue gas generated during furnace operation is collected by the fume hood and transported by the flue pipe to the dust suppression component for particulate dust separation and cooling of the flue gas, thus improving environmental friendliness.

[0007] Preferably, the dust suppression assembly includes a chimney, an inclined guide trough, a collection trough, a liquid extraction trough, a filter screen, and a water supply assembly. The exhaust pipe output end is connected to the chimney input end, the collection trough input end is connected to the inclined guide trough output end, and the inclined guide trough input end is connected to the chimney output end. A liquid extraction trough is provided on the collection trough, a filter screen is provided between the collection trough and the liquid extraction trough, and a water supply assembly is provided between the liquid extraction trough and the chimney. In use, the water supply assembly is activated, which transports water from the liquid extraction trough into the chimney. The water falls from top to bottom inside the chimney, contacting the rising flue gas. The water adheres to the dust in the flue gas, achieving separation of flue gas and dust. Then, the water with dust adhering to it is transported through the inclined guide trough into the collection trough, where the dust is deposited. The water then re-enters the liquid extraction trough through the filter screen, achieving separation of flue gas and dust.

[0008] Preferably, the water supply assembly includes a fixed base, a water pump, a suction pipe, a delivery pipe, an annular pipe, and water curtain nozzles. The annular pipe is installed inside the chimney, and multiple sets of water curtain nozzles are installed at the bottom of the annular pipe. The water pump is mounted on the fixed base, and a suction pipe is installed at the pump's input end, connecting to the bottom of the suction tank. A delivery pipe is installed at the pump's output end, connecting to the input end of the annular pipe. In use, the water pump is started, causing water from the suction tank to enter the annular pipe through the suction pipe and delivery pipe. The water entering the annular pipe is then sprayed into the chimney through the multiple sets of water curtain nozzles. The water curtain nozzles spray the water outward in a curtain shape, thus creating a water seal inside the chimney through the cooperation of the multiple water curtains, achieving the separation of dust from the flue gas.

[0009] Preferably, it also includes a slag discharge pipe and a valve. A slag discharge pipe is provided at the front end of the collection tank, and a valve is installed on the slag discharge pipe. Dust particles are deposited at the bottom of the collection tank. After a period of use, the valve is opened, so that the dust particles and a small amount of water are discharged through the slag discharge pipe, which improves convenience.

[0010] Preferably, the filter screen is made of stainless steel.

[0011] Preferably, it also includes an overflow pipe, which is provided on the collection tank; as dust particles accumulate at the bottom of the collection tank, the water level inside the collection tank rises. When the water level rises to the height of the overflow pipe, the overflow pipe discharges water and reminds the staff to clean the dust particles inside the collection tank.

[0012] Preferably, it also includes a check valve, which is installed on the exhaust pipe; the flue gas is prevented from flowing back into the flame and flue gas with the help of the check valve.

[0013] Preferably, the inside of the collection tank is provided with a smooth coating; with the help of the smooth coating, water and adhering dust particles reduce the frictional resistance of the collection tank and quickly enter the collection tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: when in use, the large amount of flue gas generated during the operation of the furnace is collected by the smoke hood and transported to the dust suppression component by the exhaust pipe for the separation of particulate dust and the cooling of the flue gas, thereby improving environmental protection.

Then, the water with dust adhering to it is transported to the inside of the collection tank 6 through the inclined guide channel 5. The dust is deposited inside the collection tank 6, and the water re-enters the liquid extraction tank 7 through the filter screen 8, thus separating the flue gas from the dust. As the dust particles accumulate at the bottom of the collection tank 6, the water level inside the collection tank 6 rises.
