Abstract

The utility model discloses a pelletizing machine for forming irregular pellet which comprises an extrusion device, a mould component and a transmission device. The extrusion device is closely connected with the mould component, the mould component consists of a concave mould disc, a material unloading board and a convex mould disc, all of which are interconnected through a connecting component, the material unloading board is arranged between the concave mould disc and the convex mould disc and moves along axial direction through a guide bar, and the transmission device is connected with the mould component through a transmission shaft sleeve and drives the mould component to rotate. The utility model can realize continuous production of irregular pellet and is in particular suitable for production of solid catalyst and catalyst carrier particle, with high qualified rate and high production efficiency.

Description

A kind of comminutor of special-shaped grain forming

Technical field

The present invention relates to a kind of comminutor, particularly a kind of comminutor of special-shaped grain forming.

Background technology

Some granular pattern products need appearance and size basic identical in use; in hole is arranged; profile can have different shape; the such product requirement neat appearance of solid catalyst or catalyst carrier for example; shape has specific (special) requirements; be generally porous abnormity particle, the inventor has applied for a patent preceding, and application number is 00259065.4; Granted publication day is July 27 calendar year 2001; denomination of invention is " a kind of automatic pelleter that is installed on the extruder head ", and this utility model is by buncher; adjuster; connecting rod and knife rest are formed, during use; the material of extruding from extruder; through behind the mould, form the shape of product requirement, carry out pelletizing with rotary cutter according to required length; making needs product; but the particle that this kind method is made, speed is not in full accord when rotating because of cutter, and the particle of formation is easily different in size; regularity is not fine; because of cut soft material with cutter, cause hole plug and problem on deformation in the product easily again, reduced the qualification rate of product.Have in the prior art and adopt and the similar formed in mould method of production ceramic methods, this method generally is to add material with paraffin to inject the mold cools down aftershaping, belongs to batch production, and production efficiency is low.

Summary of the invention

The utility model provides a kind of comminutor of special-shaped grain forming, and this comminutor can be produced the regular particle that has endoporus of complex contour continuously.

The utility model is realized by the following technical solutions:

A kind of comminutor of special-shaped grain forming; comprise extruder, die assembly and transmission device; extruder closely links to each other with die assembly; transmission device is connected with die assembly by driving sleeve; drive the rotation of die assembly; die assembly is formed, and is interconnected by connector by die dish, stripper, punch dish.

One group of nib identical with product design is set on the die dish of die assembly, in the material that comes out from extruder is squeezed into nib on the die dish, forms the required profile of product; The punch dish is made of shape and the definite column of quantity according to the required hole of product that card reaches perpendicular to card, in the nib in the column insertion die, forms the required endoporus of product; Stripper at the die dish between the punch dish, constitute by boss, guide post and demoulding cam, nib size on the boss that is provided with on the plate face and the die dish is consistent, and the hole on it is consistent with the column on the punch dish, thereby the setting of boss should corresponding coupling with nib and column; The guide post of stripper links to each other with cam disc, regulates distance between stripper and the die dish by the mobile guide bar, and the size of distance is determined the length of product.

Transmission device useable electric moter and decelerator are formed, and are used for adjusting the rotating speed of die assembly, make the speeds match of die assembly and extruder.

The utility model is because of adopting the method for die assembly moulding, prepared product is regular, the qualification rate height, and be easy to produce the particle of various complicated shapes according to different die assemblies, such as multiple special-shaped products such as Raschig ring, honeycomb ring, trifolium-shapeds, continuously shaped production efficiency height, the utility model is particularly suitable for the moulding of solid catalyst and catalyst carrier particle.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Extruder 3 of the present utility model can adopt screw plunger extruder, but be not limited thereto, die assembly 1 is by die dish 4, stripper 5 is formed with punch dish 6, and interconnect by connector, connector is that the bolt and the axle sleeve at edge constitutes, between punch dish and die dish, can move vertically, the distance that moves is exactly the length of product, transmission device 2 is made of motor 8 and decelerator 9, be fixed on the pedestal 7, be connected with die assembly by driving sleeve 10, drive the rotation of die assembly, during use, the length required according to product, the guide post 14 of regulating stripper is determined the position of good stripper, the material that extruder is extruded enters in the nib 12 of die dish 4, the boss 13 that column 15 on the punch dish 6 passes on the stripper 5 inserts in the nib of die dish, determine the shape that product is required, along with the rotation of die assembly, extruder constantly is squeezed into nib with material, after the product approval, under the effect of stripper demoulding cam 11, constantly product is ejected, reach product output continuously, change different die assemblies, can produce the product of different profiles and endoporus.

Claims
