Embodiment Construction

[0019] Such as figure 1 As shown, the complete set of equipment for the continuous production of sludge organic granules includes an internal heating energy-saving screw dryer 1, an automatic weighing machine 2, a feeder 3, a gravity-free mixer 4, a screw extrusion granulator 5, and a granulator Vibrating screen 6, tunnel cooling and sterilizing machine 7 and packaging machine 8, untreated sludge is stored in sludge bin 9, and hollow screw conveyor 10 is installed in sludge bin 9, and the sludge passes through the hollow screw conveyor 10 Enter the internal heating energy-saving screw dryer 1 for drying. The hollow shaft of the internal heating energy-saving screw dryer 1 is densely arranged with wedge-shaped hollow blades. The heat medium flows through the hollow shaft through the hollow blades, and the heat of the heat medium is used Heating the sludge to reduce the initial water content of the sludge from 65% to about 15%, and the dried sludge enters the dry sludge silo 13 ...

Abstract

The invention relates to equipment for producing organic particles, in particular to a complete set of equipment for continuously producing organic particles of sludge, which is designed aiming at sludge materials. Untreated sludge passes through a hollow spiral conveyor and enters an intrinsic heat type energy-saving screw drier for drying in order that a primary moisture of the sludge is reduced from 65 percent to 15 percent around; dry sludge is weighed by a weighing machine and added with auxiliary materials by a feeding engine; the dry sludge proportioned with the auxiliary materials enters a gravity-free mixer in order that the auxiliary materials and the dry sludge reach an optimal mixing state; a mixture enters a spiral extrusion-type pelletizer and is manufactured into granular materials; the granular materials are screened by a particle vibration sieve to produce a cylindrical finished particle with a diameter of between 5 and 6 mm and a length of about 6 mm; the finished particle completes cooling and sterilization in a tunnel-type cooling and sterilizing machine; the sterilized finished particle is sent to a packer to complete packing; and the particle vibration sieve returns bulk materials which are sieved out to the spiral extrusion type pelletizer through a feed returning helix. The equipment greatly reduces a water ratio of the sludge.

Description

technical field [0001] The invention relates to a production equipment of organic granules, in particular to a complete set of equipment for continuous production of sludge organic granules designed for sludge materials. Background technique [0002] Sewage treatment plants have to discharge a large amount of excess sludge, and the huge amount of sludge needs to be further treated. If the sludge is not properly treated and disposed of, it will be discharged directly, which will cause serious secondary pollution. Sludge is a resource that can be used as fertilizer, building material or construction soil after treatment. Sludge treatment includes concentration, dehydration, and drying. The key to existing sludge treatment is the low dehydration rate of sludge. How to increase the dehydration rate of sludge treatment to further reduce the water content of sludge is the current sludge important tasks to handle. Contents of the invention [0003] The purpose of the present in...
