Continuous stirring granulator

Abstract

The invention relates to a continuous stirring granulator. A granulating chamber is a cylinder body. An upper cap is arranged on the upper end of the cylinder body. A feeding cylinder extending to the granulating chamber is arranged at the center of the upper cap. An atomizer is connected to the lower end of a feeding pipe and extends into the granulating chamber with the feeding cylinder. One side of the feeding cylinder is connected with a spiral feeding device. The upper cap has a planar sealing structure, and is compacted by using a handwheel compactor. A fixed shaft is arranged on one side of the upper cap. A rotatable screw is sleeved on the fixed shaft. A pair of supporting seats is welded on the outer side of the cylinder body. A transverse shaft is arranged on the upper part of the supporting seats. A slide block is sleeved on the transverse shaft. A nut handle is arranged on a screw sleeved on the slide block. One end of a pair of lugs welded on the upper cap penetrates the fixed shaft below the supporting seat. The nut handle is rotated, such that the upper cap is rotationally opened with the supporting seats as a center under driving. According to the invention, stirring blades rapidly stir a powder material. After a proper amount of liquid is added, continuous stirring granulation can be carried out, such that production process is shortened. Therefore, manpower and material resources are saved, and the quality of the product is stable. The granulator can be used in continuous granulation in fields of pesticides, pharmaceuticals, granular preparations, beverages, and feedstuffs.

Description

technical field [0001] The invention belongs to the field of chemical equipment, in particular to a continuous stirring granulator. Background technique [0002] Granulators are widely used in chemical fields such as pesticides, pharmaceuticals, fertilizers, and chemical building materials. The existing stirring granulator is a cylindrical container with a high-speed rotating stirring paddle at the center of the bottom and broken flying knives on the side. Put the powder material into the cylinder, add an appropriate amount of water at the same time, start stirring and crushing, the material and water are mixed in the granulation chamber, the material flows at the same time, and bonded into granules. After reaching a certain size, the wet granules and ungranulated The fine powder is discharged from the outlet at the same time, and the machine is intermittently operated. [0003] In the granulation process, the main purpose of granulation is to obtain the required uniform a...

AI Technical Summary

Problems solved by technology

[0003] In the granulation process, the main purpose of granulation is to obtain the required uniform and narrow particle size distribution. However, for many years, the particle size distribution of this equipment product is wide, and the production mode of intermittent production limits the purpose of granulation. There are three disadvantages

First of all, intermittent production, open feeding method, low production efficiency, serious dust flying, causing a large amount of material loss, polluting the environment and endangering human health

Secondly, the product particle size distribution is wide, which affects product quality

The third is that the particle size and hardness of the product cannot be controlled. For some particles, the product particle size and hardness directly affect the product quality, and the inability to control the product particle size and hardness also limits the use of such equipment
