Roller pelletizer for sludge ceramsite granulation

Abstract

The invention relates to a roller pelletizer for sludge ceramsite granulation and belongs to the technical field of pelletizing equipment. In order to solve the problems of low efficiency and high energy consumption at present, the invention provides the roller pelletizer for sludge ceramsite granulation. The roller pelletizer comprises a frame, a driving mechanism, a driving roller and a driven roller, wherein the driving roller is arranged on the frame in a rotatable form through a first rotating shaft; the driven roller is arranged on the frame in the rotatable form through a second rotating shaft; the driving roller and the driven roller are horizontally arranged; a plurality of through holes are formed along the circumferential directions of the roller walls of the driving roller andthe driven roller; the driving mechanism is capable of driving the first rotating shaft to drive the driving roller to rotate; a flywheel is fixed on the second rotating shaft of the driven roller; the flywheel is located on the outer side of the driven roller. The through holes and the flywheel are arranged, so that the overload damage of the power source, such as a motor, in the driving mechanism can be avoided, the energy-saving effect can be achieved, the sludge ceramsite can be prevented from attaching to the through holes, the pelletizing efficiency is increased and the performance of quickly pelletizing can be realized.

Description

technical field [0001] The invention relates to a double-roll granulator used for sludge ceramsite granulation, and belongs to the technical field of granulation equipment. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, the borderless cooperation in international environmental protection has been further deepened, and urban sludge and construction sludge are usually processed into building materials such as ceramsite, which not only achieves the reduction of sludge accumulation and other environmental protection pollution, but also to achieve the comprehensive utilization of waste. [0003] Sludge ceramsite is generally granulated by a double-roll granulator. The traditional granulator usually uses a pair of double-rollers to squeeze each other for granulation. Generally, the surfaces of the two corresponding rollers are provided with grooves or a The surface of the roller is provided with grooves, and the su...

Problems solved by technology

It squeezes the grooves and protrusions on the roller to make the granulated particles better, but its motive mechanism drives the two rollers to rotate at the same time, which consumes a lot of energy and is prone to overload; therefore, it is also a common One of the reasons for granulation is to set grooves on the roller. However, because the grooves and protrusions are pressed against each other to form particles, it is easy to adhere to the grooves during the granulation process and affect the granulation. efficiency
