Combined linkage type rotor wing forced fluidized sludge drying machine

Abstract

The invention relates to a combined linkage type rotor wing forced fluidized sludge drying machine, and belongs to the technical field of environmentally-friendly equipment. The drying machine has the characteristics of large sludge treatment tonnage, easiness in adjustment of yield, safety, reliability, convenience in detachment and capability of saving energy and space. The combined linkage type rotor wing forced fluidized sludge drying machine comprises a base, wherein a furnace body is arranged on the base, the furnace body is formed by sequentially connecting at least two furnace body units, the connected two furnace body units are communicated, a hot air inlet is arranged at the upper part of the first furnace body unit, and an exhaust port is arranged at the upper part of the last furnace body unit; and at least two sludge inlet ports are arranged on the side wall of the first furnace body unit and opposite to the lower part of the hot air inlet, a driving shaft and a driven shaft, which are vertical to the direction of the feeding direction of the sludge inlet ports and parallel to each other are arranged at the bottom of each furnace body unit, a rotor wing on the drivingshaft and the rotor wing on the driven shaft are mutually arranged in a staggered manner in each furnace body unit, the driving shafts and the driven shafts are connected through a transmission case on the outer side of the furnace body, and the transmission case is connected with a motor through a gearbox.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and more specifically relates to a combined linkage rotor forced fluidized sludge dryer for treating urban sludge and coal mine wet slime with large tonnage and large output. Background technique [0002] At present, the common technology and process method adopted for thermal drying treatment of municipal sludge at home and abroad. [0003] 1. Direct heating drum drying technology. [0004] Working principle: The dehydrated sludge enters the mixer from the buffer tank and is fully mixed in proportion, and the returned sludge that has been dried (the solid content of the mixed sludge reaches 30% to 40%); it is then transported by a screw conveyor In the drum dryer, it is mixed with the hot air entering from the same end and heated intensively. The dried sludge is sent to the separator by a screw conveyor with a metering device, and the hot and humid gas discharg...

AI Technical Summary

Problems solved by technology

In the previous design, it was based on the design and budget of the single-type drying kiln, so once the equipment is installed and put into operation, the tonnage of its processed output is limited within a certain range; if the required processing capacity exceeds its design range, especially when processing a large amount, each set of drying kiln and its corresponding supporting facilities must be fully improved to complete

However, due to the occupied area and various other factors, its improvement is often difficult to achieve

[0016]Secondly, the existing problem is: the transmission structure of the existing equipment

Because of the large tonnage output, it is necessary to build another factory building, which is equivalent to building one or several similar factory workshops, and the capital investment will increase exponentially. Therefore, the main factor restricting the drying output in the prior art is that the size of the drying equipment furnace body is difficult to change.
