Description

Double-row chain for feeding chain type conveyor of analytic tower Technical Field The utility model relates to the technical field of chains, in particular to a double-row chain for a feeding chain conveyor of an analytic tower. Background As shown in figure 5 of the specification, the analytical tower feeding chain conveyor of the sintering flue gas activated carbon purification device of the steel (Zhanjiang) iron works has the advantages that the original conveyor box body is dry and free of moisture, the moisture content of activated carbon is lower than 6%, and the interior of the box body is slightly negative pressure. Because the equipment has long running time, the interior of the existing conveyor is filled with sintered sulfur-containing flue gas, and the flue gas entering the interior of the box body is condensed into dilute acid, so that the equipment has high corrosiveness. The site was observed, the operating environment was moist, and a large amount of sulfur crystals were visible on the outer surface of the box. The running time of the chain in the box body is about 8 months, the appearance of the visible part of the chain is severely corroded, a large number of sleeves (parts between the pin shaft and the roller) are damaged and fall off, and the concrete expression of the quick elongation on the chain is that the length of the chain is shortened from original once every 6-8 months to current once every week by disconnecting the knots. The double rows of chains are connected by a connecting rod 23, but lack a corrosion-proof structure. The main reason for chain elongation is that the medium corrosion and abrasion exist at each operation hinge point, which is a damage form mainly of chemical corrosion and accompanied by mechanical abrasion, which is obtained from the working condition of field equipment and observing the detached chain real object. In general, wear is moderate during the corrosion process, but due to the corrosive action, wear will be aggravated with serious consequences, especially in high temperature or humid environments. The bending attachment plate structure of the existing analytic tower feeding chain conveyor chain is mostly of a welded structure, the welded structure is low in strength, the corrosion resistance of a welded part is poor, and the analytic tower feeding chain conveyor chain cannot be supported for long-time work. There is a need for a tower feeder chain conveyor chain that is corrosion resistant and structurally strong. Disclosure of utility model The utility model provides a double-row chain for a feeding chain conveyor of an analysis tower, which is corrosion-resistant and has strong structural strength. The double-row chain for the feeding chain conveyor of the analytic tower comprises a first chain and a second chain which are controlled by a driving motor of the feeding chain conveyor of the analytic tower, wherein the first chain and the second chain are mutually parallel and synchronously moved to form the double-row chain, the first chain and the second chain are respectively provided with a bending attachment plate forming a chain plate, the bending attachment plates comprise straight plate sections and horizontal plate sections bent at 90 degrees relative to the straight plate sections, the horizontal plate sections and the straight plate sections are integrally formed, the bending attachment plates respectively installed on the first chain and the second chain are opposite in bending direction of the horizontal plate sections and face the inner side of the double-row chain, a chain connecting interval is arranged between the first chain and the second chain, rollers are respectively arranged between the first chain and the second chain, the interval between the axes of the rollers forms a roller installation interval, and the roller installation interval is larger than the chain connecting interval. According to the utility model, through the arrangement that the roller installation space is larger than the chain connection space, no physical contact between the roller and the connecting rod for connecting the two rows of chains is ensured, and extra abrasion or blockage caused by friction or collision in operation is avoided. If one roller fails due to corrosion or abrasion, the larger spacing can reduce the influence of the roller on the adjacent rollers and the overall conveying efficiency. Meanwhile, the thickness of the chain plate is adjusted from 9mm to 9.5mm, and the adjustment of the size of the chain plate not only increases the strength of the chain plate part, but also prolongs the failure time of the chain plate due to corrosion. The first chain comprises a first outer chain link and a first inner chain link which are connected end to end, the first outer chain link comprises a first abnormal-hole outer bending attachment plate and a first round hole outer chain plate which are parallel to each other, the first outer chain link
