Abstract
The utility model relates to a three-spire vacuum extruder, belonging to the extrusion equipment used in initial refining and extruding of the pug in ceramic factory and electric ceramic factory and the molding workshop section of the brick yard, which comprises two initial refining parallel shaft spiral blades (5) and (6) and an extrusion shaft spiral blade (8) at the lower part. The utility model is characterized in that: the head and tail of each lead of the extrusion shaft spiral blade (8) are broken and staggered. The utility model has the advantages of simple structure, low cost, high efficiency, dry, inflexible and deformable mud pipe, low water content, great extrusion force and other advantages, solving the technical difficulty troubled the field for years, and is more particularly suitable for producing straight pipe and straight rod type ceramic articles.
Description
The triple helical vacuum-extruder belongs to porcelain factory, the pug kneading of electroceramics factory is extruded and brick field pressing section extrusion equipment.
At present, porcelain factory, electroceramics factory, the used extruder of brick field mainly are made up of motor, reductor, diaxon or three spiral leaves, motor drives three pivoting leafs by reductor, by parallel diaxon with the pug kneading, extrude by the outlet of required article shape for the 3rd, the 3rd is extruded each helical pitch of spiral leaf all is to join end to end to form uninterrupted spiral leaf.As disclosed application number: 96228016.X in " Chinese patent " on April 15th, 1998, the applying date: on June 4th, 96, applicant: Kang Fengming, utility model title: twin shaft charging single shaft extruder, this twin shaft charging single shaft extruder mainly contains fuselage, reduction box, extrudes reamer, composition such as charging reamer, reducing cylinder, head, machine mouth.Adopted and the parallel charging reamer of extruding reamer, reduced the quantity of consumable accessory to greatest extent, for brick field has been saved a large number of fittings cost and maintenance cost, and the productivity ratio of having avoided causing because of the interrupted feeding of soil compressing plate is hanged down and the bad phenomenon of mud bar packing.Although this kind equipment is widely adopted at present, the subject matter that exists is: the mud bar section stress of extruding is inhomogeneous, and is obviously crooked after the especially crowded sludge out pipe drying, and the pug moisture that prior art is extruded is big, all more than 19%, it is big, yielding to consume energy when dry, burns till the back and is out of shape bigger.Be difficult for producing straight tube class, straight excellent class ceramic.For many years, be the insoluble technical barrier in this area always.
The purpose of this utility model just is to overcome the deficiency that prior art exists, provide a kind of simple in structure, cost is low, efficient is high, the mud pipe drying of extruding, not crooked, indeformable, moisture is low, the triple helical vacuum-extruder that the power of extruding is big, solve the insoluble for many years technical barrier in this area, be particularly suitable for producing straight tube class, straight excellent class ceramic.
The purpose of this utility model realizes in the following way:
This triple helical vacuum-extruder comprises: two kneading parallel axes spiral leaves 5,6, and the release axle spiral leaf 8 of bottom setting is characterized in that: an initial and end of releasing axle spiral leaf 8 each helical pitch disconnects and dislocation.
The purpose of this utility model also can realize in the following way:
Described triple helical vacuum-extruder is characterized in that: after the described initial and end of releasing axle spiral leaf 8 each helical pitch disconnects, separate by spacer, each spiral leaf initial and end is for axis misalignment.
Described triple helical vacuum-extruder is characterized in that: the distance that the described initial and end of releasing axle spiral leaf 8 each helical pitch disconnects is that 30-50mm is best.
Described triple helical vacuum-extruder is characterized in that: the initial and end of described release axle spiral leaf 8 each helical pitch is that 30-50mm is best for the distance of axis misalignment.
Triple helical vacuum-extruder of the present utility model, main inventive point is: release the initial and end disconnection of axle spiral leaf 8 each helical pitch and the particular design of misconstruction, this design makes extruder extrude power to improve greatly, can extrude the low moisture pug of water content 16%, the particularly straight mud pipe of extruded product, excellent class stress evenly, not flexible after burning till, the distortion of drying.And have simple in structure, cost is low, the efficient advantages of higher, and is easy to install, a tractor serves several purposes has solved the insoluble for many years technical barrier in this area, is particularly suitable for producing straight tube class, straight excellent class ceramic.Be present porcelain factory, the pug kneading of electroceramics factory is extruded and brick field pressing section update extrusion equipment.
Fig. 1 is the structure cross-sectional schematic of triple helical vacuum-extruder of the present utility model.It is the most preferred embodiment of triple helical vacuum-extruder of the present utility model.Among Fig. 1: 1 kneading driving shaft motor, 2 kneading driving shaft reductors 3 advance the 7 release axle spiral leaves disconnections 8 of pug bucket 4 vacuum chambers 5 kneading driving shaft spiral leaves 6 kneading driven shaft spiral leaves and release axle spiral leaves 9 release axle reductors 10 release spindle motors.Be described further below in conjunction with the operation principle and the course of work of accompanying drawing: the triple helical vacuum-extruder of making a playscript with stage directions utility model as shown in Figure 1 triple helical vacuum-extruder of the present utility model, kneading driving shaft spiral leaf 5, driven shaft spiral leaf 6 are installed in the kneading housing during making, kneading housing top is by advancing pug bucket 3, vacuum chamber 4, motor 1, reductor 2 are installed successively, kneading driving shaft spiral leaf 5 on the kneading driving shaft; Pitch wheel is installed in kneading driving shaft spiral leaf 5, on the kneading driven shaft spiral leaf 6, the kneading shell end is provided with the through hole that links to each other with mud feeding drum, the last end of axle of releasing axle spiral leaf 8 is connected with motor 10, reductor 9, release between axle spiral leaf 8 each helical pitch and disconnect certain distance, generally between 20-80mm, 30-50mm is best, the head of each helical pitch, after tail disconnects, separate by spacer, each spiral leaf head, tail is for axis misalignment, release the head of axle spiral leaf 8 each helical pitch, generally also between 20-80mm, 30-50mm is best to tail for the distance of axis misalignment.Mud feeding drum export department is provided with difform outlet, when pug is in the kneading housing that advances pug bucket 3 and enter the triple helical vacuum-extruder, motor 1 is by reductor 2 gear driven driving shaft spiral leaves 5 and driven shaft spiral leaf 6, rotate round about, under vacuum state, pug is carried out abundant kneading, the through hole that links to each other with mud feeding drum that pug after the kneading is provided with through the kneading shell end enters in the mud feeding drum, under the drive of releasing spindle motor 10, driving release axle spiral leaf 8 through reductor 9 rotates, owing to release between axle spiral leaf 8 each helical pitch and disconnect certain distance, and separate with spacer, each spiral leaf head and the tail is for the axis misalignment certain distance, cut off the rule of pug in mud feeding drum like this and arranged, pug is reconfigured, the pug uniform and consistent stress behind the finished product is extruded in realization.Solved behind the clay drying because the even distortion that produces of unbalanced stress.Owing to release disconnection, the dislocation of axle spiral leaf 8, increase the resistance of pug and spiral leaf simultaneously, prevented the slip between pug and the spiral leaf, improved the plasticating capacity of releasing axle spiral leaf 8, can extrude the low moisture pug of water content 16%.
