Description
Technical Field
The invention relates to the field of sludge treatment, in particular to a material distribution conveying device.
Background
For the case of drying wet materials such as sludge by a mesh belt continuous dryer, a feeding device generally selects an inclined feeding screw, a scraper conveyor, a tube chain conveyor, a belt conveyor or the like. The blanking mouth width of these feeding devices is much smaller than the width of the mesh belt. For example, the width of a shaftless U-shaped groove screw conveyor adopted by general water service equipment manufacturers or sludge treatment units is generally 240-400 mm, the blanking width of other types of devices is also in the range and even smaller, and the width of a conveying mesh belt of a belt type dryer exceeds 1.2m and reaches more than 1.5 m. Wet materials directly fall from a blanking port of a feeding and transferring device to a net belt to be always in a stacking state. Therefore, obviously, the materials cannot be dispersed, and much hot air passing through the mesh belt flows away from gaps at two sides of the stacked wet materials, so that the hot air cannot effectively exchange heat with the materials, remove the moisture of the materials, and the drying effect is greatly reduced. Therefore, the material is required to be uniformly sprinkled over the whole web width by adopting a material distribution measure, so that the material is formed into a thin layer, and local accumulation is avoided as much as possible.
On the other hand, at present, a belt dryer is adopted for drying sludge materials, and in order to solve the problem of connection transition between a feeding device and a drying net belt or a slitting forming device, a buffer bin is adopted, and a rotary type distributor or a vibration distributor is adopted. The buffer bin may re-bond the dispersed pugs into clusters. The swing arm length of the rotary lifting distributing device is longer, the track of the blanking head is an arc, the occupied space is large, and dead angles exist in the distribution. The vibration distributing device uses more than two driving motors, the weight of the machine body is large, and the problems of vibration noise and stability are unavoidable.
