Description

Technical Field

[0001] The utility model relates to the technical field of flue purification, in particular to a roasting flue purification material suction device. Background Art

[0002] During the carbon roasting production process, the asphalt in the carbon block produces gas after roasting. The gas flows into the purified flue under the action of negative pressure, forming a large amount of coke attached to the inner wall of the flue. The coke is a flammable substance, so the flue coke is cleaned every quarter. At present, the flue coke is generally cleaned manually, which requires a large number of people and is time-consuming and laborious. The personnel need to lift the cleaned coke out of the flue bag by bag, which is very labor-intensive. There is a lot of dust in the narrow flue, which also affects the health of the operators. In view of the above problems, a roasting flue purification suction device is developed. Utility Model Content

[0016] like Figure 1-Figure 2 As shown, a roasting flue purification suction device includes a dust collecting bin 1. The dust collecting bin is welded with a 6mm steel plate with good sealing performance to form a large-volume ash box. In order to increase the rigidity of the patterned steel plate, reinforcing ribs are added on the patterned steel plate. It mainly collects dust and coke, and is made into a sealed structure around to prevent dust leakage.

[0017] The dust collecting bin 1 is provided with a dust collecting pipe 2 which is in communication therewith, and the dust collecting pipe 2 is used for collecting sintered materials and dust in the flue.

[0018] Multiple bag dust collectors 3 are evenly spaced inside the dust collecting bin 1, and a vibrator 4 is installed above the multiple bag dust collectors 3. The bag dust collector 3 can filter the particles and dust in the air sucked by the dust suction pipe 2 and capture them on the surface or inside of the bag. Through the fine pore size and surface fibers of the bag, the entry and diffusion of particles can be effectively prevented, and the content of particles in the air can be reduced. The vibrator 4 can vibrate the bag dust collector 3 to cause the dust on the bag dust collector 3 to fall off.

[0019] The bottom of the dust collecting bin 1 is provided with an ash discharge port 5 for discharging the collected dust into a ton bag for recycling.

[0020] The utility model also includes an ash bin bracket 6, and the dust bin 1 is fixedly mounted on the ash bin bracket 6. The ash bin bracket 6 is mainly made of channel steel welding, and is used to support the sealed box body. When dust collection starts, due to large vibration, the ash bin bracket plays a role in stabilizing the dust bin 1. In addition, the bottom of the ash bin bracket 6 is symmetrically rotatably mounted with multiple sets of running wheels 7, which is convenient for moving the device.

[0021] The top of the dust collecting bin 1 is connected to the Roots blower 9 through a negative pressure pipe 8. The Roots blower 9 is installed on a motor bracket 10. A dust collecting motor 11 for driving the Roots blower 9 is also installed on the motor bracket 10. The motor bracket 10 is used to support and fix the mechanical parts of the dust collecting motor 11. When the dust collecting motor 11 is operating normally, the high-speed rotation of the motor rotor will generate inertia force. The motor bracket 10 can support and fix the dust collecting motor 11 to avoid the motor from shaking, reduce the machine noise, and prevent the motor from being damaged and affecting its service life. Under the driving action of the dust collecting motor, the Roots blower separates the air inlet through the meshing of a pair of rotors. The rotors are driven by a pair of synchronous gears and move in the opposite direction to push the inhaled gas from the air intake to the exhaust port in a compressed manner. At the moment the gas reaches the exhaust port, it is pressurized due to the backflow of the high-pressure gas on the exhaust side, thereby completing the gas transportation. When the Roots blower is working, the negative pressure pipe is connected to the dust collecting bin 1 to generate negative pressure, so that the pressure distribution of the fluid inside the pipeline changes, thereby achieving the purpose of dust collection.

[0022] The Roots blower is provided with a Roots blower silencer 12, which can reduce the intake / exhaust noise of the blower and can also be used to reduce the noise of the pipeline.

[0023] In addition, the utility model further comprises an electrical control cabinet 13 installed on the ash bin bracket 10, and the vibrator 4 and the dust collecting motor 11 are electrically connected to the electrical control cabinet 13. In normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch on the electrical control cabinet 13, thereby controlling the normal operation of the vibrator and the dust collecting motor. In case of failure or abnormal operation, the circuit can be disconnected or an alarm can be given by means of a protective electrical appliance.

[0024] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
