Description

Technical Field

[0001] The invention relates to the technical field of carbon black production, in particular to a recovery device with an impurity removal structure. Background Art

[0002] Carbon black is a black powdery substance formed by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its main component is elemental carbon, and it contains a small amount of oxygen, hydrogen and sulfur. Carbon black particles are approximately spherical, with a particle size between 10 and 500 μm. Many particles often fuse or agglomerate into three-dimensional bonded branches or fibrous aggregates. In rubber processing, it is added to rubber through mixing as a reinforcing agent and filler. Carbon black is one of the oldest industrial products.

[0003] There are three main methods for producing carbon black: furnace method, tank method and thermal cracking method. The most widely used is the furnace method. Air and fuel are burned in a reaction furnace. The raw materials are atomized and sprayed into the burning flame. Carbon black is generated through high-temperature pyrolysis. The carbon black is suspended in the residual gas to form flue gas. The flue gas is quickly cooled and sent to an air preheater and an oil preheater for further cooling. Finally, it is sent to a bag filter. The separated carbon black is sent to a granulator for granulation and then dried in a dryer. This type of carbon black is called furnace black, which is the type with the largest output and the most varieties among carbon black varieties.

[0004] Among them, bag filter separation is the key step. Bag filter is a kind of equipment for gas filtering and purification, which is often composed of several filter bags combined into a group, and several groups into one device. When the dust-containing gas passes through the filter bag, the dust particles in the gas are trapped on the bag, and the clean gas is discharged from the exhaust pipe through the filter bag. In the production of carbon black, the gas contains a large amount of iron filings. The current bag filter lacks an effective structure to remove iron filings impurities in carbon black. As time accumulates, it will damage and clog the bag, resulting in poor impurity removal effect and inconvenient impurity recovery. In view of this, we propose a recovery device with an impurity removal structure. Summary of the invention

It can be recycled. When the rotating shaft 1003 rotates, it will drive the cam 1101 to rotate, so that the cam 1101 is away from one end of the rotating shaft 1003 and intermittently pushes the filter plate 1103 downward, thereby cooperating with the cross 1006 and the spring 1102 to make the filter plate 1103 reciprocate up and down, thereby achieving a vibration effect, so that the carbon black fine powder can be screened out while the impurities are left in the filter plate 1103. The baffle 1104 has the effect of blocking the impurities from rolling out. When the screened carbon black accumulates inside the discharge hopper 1202, the carbon black is prevented from flowing out smoothly. The rotation of the rotating rod 1007 will drive the auger rod 1201 to rotate, thereby accelerating the outflow of carbon black, and finally the clean air will be discharged from the outlet pipe 5.
