Dual-roller vibrating mechanism

Abstract

The invention relates to the field of fertilizer production, in particular to a dual-roller vibrating mechanism. The mechanism comprises two rollers which are same in structure and provided with parallel center axes on the same horizontal plane, a sliding rod is arranged between the two rollers in the vertical direction, the upper end and the lower end of the sliding rod are in sliding connectionto a rack, the two ends of the rack are movably connected with pressing rods through supporting rods, the ends, pointing to the sliding rod, of the pressing rods are in hinged connection to the sliding rod through pin shafts, the other ends are fixedly provided with hammer blocks, a gear rack is fixed to the position, close to the side walls of the rollers, of the middle of the sliding rod, and the gear racks are connected with a driving mechanism. According to the dual-roller vibrating mechanism, the whole process does not need an extra driving device, equipment investment is saved, maintaining cost is saved, economic benefits are improved, the structure is simple, through one circulation process, two rollers can be hammered at two times at the same time, the hammering effect is good, andefficiency is high.

Description

technical field

[0001] The invention relates to the field of fertilizer production, in particular to a double-drum vibrating mechanism. Background technique

[0002] In the process of producing compound fertilizer by drum granulation method, it is often necessary to pass water vapor to condition and humidify the raw material, so that the fertilizer can be better bonded into balls. However, excessive moisture content in compound fertilizer products will affect the quality of the product. Therefore, in order to reduce the moisture content in the product to the acceptable range, the compound fertilizer is generally dried by a rotary drum dryer. During the drying process, due to the high moisture content of the compound fertilizer just entering the drum dryer, it is easy to get stuck on the drum wall of the drum dryer, which seriously affects the production efficiency and quality of the compound fertilizer product. At the same time, due to the large waste of heat transported fr...
