Description

Technical Field

[0001] The present invention relates to a detachable, rotatable, uniformly heated, and flue gas collection device, and more particularly to an integrated muffle furnace. Background Art

[0002] A muffle furnace is a common heating device widely used in universities, research institutions, the pharmaceutical industry, etc. However, there are some problems in the existing muffle furnaces. When using the muffle furnace to burn biochar, the straw material particles are first placed in a crucible, and then the crucible is placed in the muffle furnace for heating and burning. Since the straw materials are stacked in the crucible and cannot rotate or move, the surface temperature of the straw material stack and the temperature at the center of the material stack are inconsistent. The surface of the burned straw materials has been carbonized, but there is no change in the middle of the material stack. The straw materials cannot be evenly heated and carbonized. Moreover, when burning biochar, a large amount of flue gas is generated by the straw materials. Since these flue gases are directly discharged from the exhaust pipe of the muffle furnace, the flue gases in the furnace and the flue gases in the exhaust pipe are uneven in temperature (hot and cold). The flue gases are liquefied when encountering cold, flowing back into the exhaust pipe. There is a large amount of grease in the flue gases, blocking the exhaust pipe and preventing normal exhaust, and none of them can collect the flue gases by good liquefaction. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, achieve the uniform heating of crop straws, obtain biochar with uniform carbonization, and reasonably recycle flue gases, etc. The present invention will provide an integrated muffle furnace with a detachable and rotatable uniformly heated device and an oil fume recovery and liquefaction device.

The motor is connected to the detachable shaft connection device I through the flywheel connection group; the pull-out carbon burning chamber structure includes a carbon burning chamber, a detachable shaft connection device II, an exhaust pipe, and a furnace door. The detachable shaft connection device II is arranged outside the carbon burning chamber. The exhaust pipe passes through the carbon burning chamber and the furnace door and is connected to the condensation device; the heating chamber main body and the pull-out carbon burning chamber structure form a detachable connection through the detachable shaft connection device I and the detachable shaft connection device II.

[0021] Embodiment:

[0022] The integrated muffle furnace includes a heating chamber main body, a pull-out charcoal burning chamber structure, and a condensation device; the heating chamber main body includes a heating chamber 19, a motor 1, a flywheel connection group 18, a detachable shaft connection device I 17, and a heating resistance wire 3. There is a cavity in the heating chamber 19, and a heating resistance wire 3 is arranged in the cavity. The motor 1 is connected to the detachable shaft connection device I 17 through the flywheel connection group 18; the pull-out charcoal burning chamber structure includes a charcoal burning chamber 4, a detachable shaft connection device II 15, a smoke exhaust pipe 20, and a furnace door 6. The detachable shaft connection device II 15 is arranged outside the charcoal burning chamber 4. The smoke exhaust pipe 20 passes through the charcoal burning chamber 4 and the furnace door 6 and is connected to the condensation device; the heating chamber main body and the pull-out charcoal burning chamber 4 structure form a detachable connection through the detachable shaft connection device I 17 and the detachable shaft connection device II 15. The flywheel connection group 18 includes a small flywheel 18-1, a transmission belt 18-2, and a large flywheel 18-3. The small flywheel 18-1 is connected to the motor 1, and the small flywheel 18-1 is connected to the large flywheel 18-3 through the transmission belt 18-2. The charcoal burning chamber 4 is provided with a feeding and discharging port 16. The detachable shaft connection device II 15 is provided with a pull-out support rod 5, which is connected to the furnace door 6. A detachable shaft connection device III 14 is arranged between the charcoal burning chamber 4 and the furnace door 6. The furnace door 6 matches the opening of the heating chamber 19 main body, and the furnace door 6 is provided with a pull-out handle 7. The condensation device includes a serpentine condensation pipe 10, a condensation pipe water inlet 8, a condensation pipe water outlet 11, and a beaker 9. The serpentine condensation pipe 10 is provided with a condensation pipe water inlet 8 and a condensation pipe water outlet 11. A beaker 9 is arranged below the outlet of the serpentine condensation pipe 10. The smoke exhaust pipe 20 is provided with a gas pressure gauge 13 and a gas pressure reducing valve 12. A base 2 is arranged below the heating chamber 19 main body.

[0023] The working principle of the present invention is to put straw materials into the carbonization chamber 4, push the carbonization chamber 4 into the heating chamber 19, connect the detachable shaft coupling device one 17 with the detachable shaft coupling device two 15, connect the furnace door 6 with the heating chamber main body, close the carbonization chamber 4 inside the heating chamber main body, start heating the heating resistance wires 3 in three directions in the heating chamber 19, and then drive the carbonization chamber 4 to rotate at a constant speed by the motor 1 to make it evenly heated and carbonized. The flue gas generated by heating the straw materials in the carbonization chamber 4 generates a certain pressure in the furnace. When the pressure reaches the threshold value on the gas pressure gauge 13, open the gas pressure reducing valve 12 to make the flue gas quickly enter the serpentine condenser 10 through the exhaust pipe 20 to avoid the accumulation and blockage of flue gas tar in the exhaust pipe 20 and the carbonization chamber 4. Thus, the flue gas liquefies from the serpentine condenser 1, and the beaker 9 is used to collect the flue gas wood vinegar liquid. In addition, the pull-out carbonization chamber designed for this muffle furnace can facilitate the replacement of the heating resistance wire 3 when it is damaged during long-term use. The carbonization chamber 4 can be pulled out to replace the heating resistance wire 3, which saves time and effort and improves and extends the service life of the muffle furnace.
