Planetary wheel type concave arc roller surface ring die granulation device

Abstract

Belonging to the technical field of material compression granulation, the invention relates to a planetary wheel type concave arc roller surface ring die granulation device. The device comprises a transmission drum, a forming roller, a forming roller sleeve, extrusion rollers, feeding scraping plates and a mounting rack. The forming roller is arranged in the transmission drum, two extrusion rollers and two feeding scraping plates are symmetrically arranged between the forming roller and the transmission drum, the extrusion rollers are respectively in engaged transmission with the forming roller and the transmission drum, the feeding scraping plates and the extrusion rollers are arranged at intervals and are respectively connected to the forming roller through the mounting rack. The formingroller sleeve is disposed on the forming roller, and the material extruded by the extrusion rollers and the forming roller is discharged through an inner cavity of the forming roller sleeve. According to the invention, the extrusion rollers are in transmission with the transmission drum and the forming roller respectively, by means of the two feeding scraping plates, materials are evenly distributed at the periphery of the forming roller, the extrusion rollers and the forming roller are utilized to extrude materials, material granules are discharged through the inner cavity of the forming roller sleeve, the transmission is stable, the material distribution is uniform, the prepared material granules are uniform, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of material compression granulation, in particular to a planetary wheel type concave arc roller surface ring mold granulation device. Background technique [0002] In the field of powder material compression granulation, the ring die granulation technology has a relatively mature market background since it was proposed, and is widely used in major production enterprises. The traditional ring die granulation equipment consumes a lot of energy, the parts are seriously worn, and the problems of high failure rate have become the key problems that need to be solved urgently at this stage. [0003] The extrusion form of the traditional ring die granulation device is to extrude the powder material from the inner cavity of the ring die through the roller surface of the ring die. Due to the relative slip between the particles of the powder material caused by the pressing force, resulting in To form a circulation of ...

Problems solved by technology

[0002] In the field of powder material compression granulation, the ring die granulation technology has a relatively mature market background since it was proposed, and is widely used in major production enterprises. The traditional ring die granulation equipment consumes a lot of energy, the parts are seriously worn out, and the problems of high failure rate have become the key problems to be solved urgently at this stage

[0003] The extrusion form of the traditional ring die granulation device is to extrude the powder material from the inner cavity of the ring die through the roller surface of the ring die. Due to the relative slip between the particles of the powder material caused by the pressing force, resulting in To form the circulation of powder materials, grinding the surface of the ring die roller, resulting in energy loss

[0004] The distance between the feeding port and the pressure roller of the traditional ring die granulation device is relatively close. When the ring die is running at high speed, the scraper cannot spread the powder material evenly in time, which increases the unevenness of the ring die movement and generates vibration. Affect the granulation effect and easily cause the clogging of the die hole
