Abstract
The utility model relates to a piston type strip squeezing machine, which is used for the strip squeezing forming of powder-shaped materials. The utility model is mainly characterized in that a liner cylinder is arranged in a cylinder body; a piston arranged in the liner cylinder is connected with a propelling screw rod; through rotating a rotary sleeve cylinder, the propelling screw rod connected with the rotary sleeve cylinder is propelled, and simultaneously, the piston is driven to do the parallel movement in the liner cylinder so as to squeeze the materials; after passing through an opening on a hole plate, the materials can be formed to be the required strip-shaped objects. The piston type strip squeezing machine of the utility model can be used for the strip squeezing forming of catalyst, desiccant, adsorbent, and food.
Description
The utility model belongs to a kind of former of powder material---the piston type banded extruder.
In heterogeneous catalysis technology, diameter, the cross sectional shape of catalyst granules there are different requirements, therefore in the Preparation of catalysts process, need to use extrusion equipment.At present, industrial great majority adopt screw propulsion banded extruder (Alvin B.Stiles, the Cat-alyst Manufacture of continuous feeding and discharging, New York and Basel, P66,1983) this equipment forming processes amount is big, but complex structure, cost height.Porous material make-up machine described in the U.S. Pat P2517707 is the piston type banded extruder of intermittent feeding, its simple structure, and easy to manufacture, cost is low, therefore still is widely adopted so far.This class piston type banded extruder partly is made up of cylindrical shell, piston and propulsive mechanism, orifice plate etc.Owing to need in using often to change molding materials, in order to prevent mutual pollution, usually orifice plate is become dismountable structure with plunger designs, so that clean with the back, but cylindrical shell generally all is fixed on the support, cleans extremely inconvenience; Because cylindrical shell is fixture, therefore requiring to do parallel mobile piston and propulsive mechanism and cylindrical shell thereof therein has higher concentricity, otherwise piston easily blocks when mobile in cylindrical shell, and the pushing ram of piston is also often because of the discontinuity bending.
The purpose of this utility model provides a kind of improved piston type banded extruder, and mainly adopting increases a mobilizable lining structure in cylindrical shell, thereby overcomes the shortcoming that above-mentioned existing banded extruder exists effectively.
Characteristics of the present utility model are that with manual mode or motor be power, rotate turnbarrel, the augering screw that its internal thread promotion is attached thereto, drive piston simultaneously and in lining, do parallel moving, the powder material that is modulated into pasty state in the lining is put in extruding in advance, make it by the perforate on the orifice plate, be shaped to required bar.
Accompanying drawing is a banded extruder of the present utility model, its structure is: cylindrical shell (3) is fixed on the frame (8), lining (4) is housed in the cylindrical shell, piston therebetween (5) is connected with augering screw (2), and augering screw and turnbarrel (1) are by being threaded, orifice plate (6) places the top ends of lining, by gland (7) it is compressed.
Leave certain clearance between described lining (4) and the cylindrical shell (3), it can be moved radially, among a small circle with the concentricity of automatic conditioning equipment; The percent opening of described orifice plate (6) is 1～30%, is preferably 3～10%, and the shape of perforate can be split into as required and comprise circle, ellipse, trilobal, annular or honeycombed.
Advantage of the present utility model: because all parts that contact with molding materials are movable part, therefore, forming operation all can clean outward by the machine that split out easily later on; Again owing to leave certain clearance between lining and the cylindrical shell, therefore, in the forming operation process, concentricity as cylindrical shell and the piston and the propulsive mechanism thereof of fixture, can among a small circle, regulate automatically, overcome piston and easily blocked, the disadvantage of the easy stressed bending of augering screw; Parts such as cylindrical shell and frame can adopt integral cast processing, are convenient to produce by batch, can further reduce cost; Easy and simple to handle, can select suitable percent opening according to different material, adopt manual operations also can extrude closely knit, uniform strip-shaped materials.
The utility model also can be used for the extruded moulding of drier, adsorbent and food except can be used for the shaping of catalyst extrusion.
