Abstract

The utility model relates to a direct and automatic grain cutting machine installed on an extruder head, which is composed of an adjustable speed motor, an adjustor, a connecting rod, a cutter, a cutter frame and a mold, wherein the cutter frame is connected with the adjustable speed motor through the connecting rod, the adjustor is composed of a radial adjustor and an axial adjustor which are connected through a diverter, and the cutter frame is provided with a symmetrical structure which is composed of a base and a pressing block. According to material characteristics, a user can use different special cutters or cutter blades sold on markets; the angular speed, the line speed and the position of the cuter of the grain cutting machine can be freely adjusted to ensure that cut grains are regular and smooth. The user who uses different molds can cut out the grains into different shapes, and the diameters and the length of the grains which can be cut by the utility model respectively range from 1 mm to 20 mm and 0.5 mm to 20 mm. The utility model is especially suitable for cutting required grains of solid catalyst and catalyst carriers.

Description

A kind of automatic pelleter that is installed on the extruder head

The utility model relates to a kind of granulate equipment, the pelletizing special equipment of special materials such as particularly a kind of solid catalyst or catalyst carrier.

In solid catalyst or catalyst carrier preparation, mostly require its particle regular, shape is special, as the special-shaped particle of porous, and present granulate equipment can not satisfy this requirement well, the applicant has retrieved Inpadoc, the engineering index database, the Chinese patent storehouse, SWIC is found general pertinent literature altogether, 53 pieces of patents, one piece of wherein closely related patent, the patent No. is DE38209801A1, be a kind of protector of mobile cutting knife, its principal right requires to have protective cover for cutting knife, guarantees safety, but this patent can not satisfy abnormal shape, the pelletizing requirement of porous, thereby in literature search, do not find required granulate equipment technical data yet.

The purpose of this utility model is to provide a kind of granulate equipment that can prepare different shape, multiple endoporus, is particularly suited for the granulate equipment of the required particle of solid catalyst and catalyst carrier.

The utility model purpose realizes by the following technical solutions:

The automatic pelleter that is installed on the extruder head is made up of buncher, connecting rod, knife rest, mould, adjuster; buncher gets final product with commercially available buncher; belong to prior art; knife rest links to each other with buncher by connecting rod; knife rest is made the symmetrical structure of energy clamping blade; form by base, briquetting; requirement according to product; mould is made corresponding shape and is installed on the extruder head; adjuster is made up of axial adjustment device and radial actuator, and axial adjustment device and radial actuator link together by steering gear.

The material that comes out from extruder is through having had the shape of product requirement behind the mould, adjust rotating speed of motor, the cutter that links to each other with buncher is under different rotating speeds, can excise the particle of different length, the angle of cutting knife is regulated by radial actuator and axial adjustment device, but the equal free adjustment of cutting knife front, rear, left and right distance, thereby guaranteed in the pelletizing process, do not stop extruding continuously of material, the particle that gets of system is level and smooth, and particle is neat; The cutter that the utility model is used can use different dedicated tools or commercially available blade to get final product according to material characteristic.

The utility model is owing to be directly installed on the extruder, the material that comes out from extruder, directly pelletizing automatically, do not need to derive and oven dry, economize on the use of funds and equipment, be applicable to multiple granularity, the pelletizing requirement of multiple shaped particles, but the pelletizing diameter is in the 1-20mm scope, and its length range is particularly suitable for solid catalyst and catalyst carrier particle requirement at the particle of 0.5-20mm different shape.

Fig. 1 is installed in the directly automatic pelleter structural representation on the extruder head

Among the figure: 1 buncher, 2 knife rests, 3 cutters, 4 moulds, 5 products, 6 axial adjustment devices, 7 radial actuator, 8 steering gears, 9 axial adjustment handles, 10 radiai adjustment handles, 11 extruders

Fig. 2 cutter frame structure figure

Among the figure: 12 briquettings, 13 bases, 14 fastening bolts

Below in conjunction with accompanying drawing the utility model is described further;

Axial adjustment device of the present utility model is that screw rod is regulated, and radial actuator is that gear is regulated, and the linear velocity of cutting knife can be regulated by radial actuator as required.

When the utility model uses, by axial adjustment device handle 9, radial actuator handle 10 and steering gear 8 relative position of cutter 3 and mould 4 is adjusted earlier, adjust rotating speed of motor according to manufacturing technique requirent then, last starter motor drives knife rest 2, cutter 3 rotations are along with the material that extruder 11 is constantly extruded, behind the process mould, cut out required difform product, the shape of product realizes by changing mould.Mould can be made all size and shape according to the product required form, and the shape of the product that is cut out can be different shapes such as column type porous, polygon prism type porous, gear type porous.

Claims
