Suspended sludge granulator

Abstract

The invention relates to a suspension type sludge granulator which comprises a machine base, a driving mechanism, a box body, a supporting cavity, a mounting cavity and a lubricating cavity, the supporting cavity, the mounting cavity and the lubricating cavity are sequentially arranged above the box body, and a bottom plate, a circular mold and a guide ring are arranged in the supporting cavity; three compression roller assemblies are arranged in the mounting cavity in the circumferential direction, and each compression roller assembly comprises an eccentric sleeve, an adjusting gear, a compression roller shaft and a compression roller; the eccentric sleeve and the compression roller shaft are not coaxial, a material raising frame is arranged below the mounting cavity, and the material raising frame and the compression roller are alternately arranged in the ring die in the ring direction; a gap adjusting mechanism is arranged on the lubricating cavity, the gap adjusting mechanism comprises an inner gear ring and a speed reducer which are in gear transmission connection, and three adjusting gears are meshed with the inner gear ring respectively; a discharging pipe is arranged on the lubricating cavity, and the lower end of the discharging pipe extends downwards to be arranged in the middle of the circular mold. The problems of non-uniform feeding, lubricating of rotating parts, difficulty in adjustment of roller die gaps, overflow of raw materials and abrasion of parts of the sludge granulator are solved.

Description

technical field [0001] The invention relates to the technical field of sludge granulation, in particular to a suspension type sludge granulator. Background technique [0002] Sludge granulator is one of the main equipments of sludge pyrolysis and gasification projects, and occupies an important position in sludge pyrolysis and gasification projects. It is found through the test operation of the gasifier that the granulation strength must meet the requirements to meet the normal operation of the gasifier. Otherwise, serious problems such as coking, slagging, large amount of combustible dust, and clogging of the furnace grates are likely to occur. [0003] The following problems occur during the use of the existing sludge granulator in our unit: 1. When the raw materials enter the granulator, the incoming materials cannot be guided, and the uniformity of the raw materials in the granulation chamber cannot be guaranteed. 2. In the process of sludge granulation, the proportion ...
