Embodiment Construction
[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.
[0023] Such as Figure 1-4 As shown, a cut-in powder molding granulator includes: a feeding device, a granulating device and a drying discharge device arranged in sequence, and the granulating device includes an extrusion tank 1, and a sleeve cone arranged in the extrusion tank 1 body 3, the sleeve cone body 3 includes the extrusion cone 4 arranged on the outer layer and the cutting cone 7 of the inner layer. 4 is able to rotate relative to the cutting cone 7 along its axis. Extrusion holes 5 are arranged on the extrusion cone 4, and the extrusion holes 5 are arranged into several horizontal circles on the extrusion cone 4, and several grid ...

The invention relates to a cut-in type powder forming pelletizer which comprises a feeding device, a pelletizing device and a drying and discharging device. The feeding device, the pelletizing device and the drying and discharging device are arranged in sequence. The pelletizing device comprises an extruding tank and a sleeve cone arranged in the extruding tank, the sleeve cone comprises an extruding cone body on the outer layer and a cutting cone body on the inner layer, the large end of the sleeve cone is communicated with the drying and discharging device downwards, the feeding device is communicated with the extruding tank in a sealing mode, and the extruding cone body can rotate round the axis of itself relative to the cutting cone body. Large inner pressure is generated in the extruding tank through materials constantly extruded into the extruding tank, the materials are extruded out of extruding holes in a strip shape, and the materials are cut into pellets through relative motion of the cutting cone body and the extruding cone body. Due to the fact that a grid ring corresponds to a horizontal ring in position, the strip-shaped materials entering grid holes can be cut off, and the length of the pellets can be adjusted. A driving device is arranged above, and pelletizing cannot be influenced. The materials can be extruded to be of a strip-shaped structure through a cap, and the cap can actively extract the materials. The drying and discharging device can dry and transfer the manufactured pellets.
Description
technical field [0001] The invention relates to a granulation device in the field of powder metallurgy, in particular to a cutting-in powder forming granulator. Background technique [0002] Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. [0003] In the previous process of powder metallurgy, after adding paraffin, rubber, engine oil and plasticizer, etc., they are fully stirred and mixed to form a dough similar...
