Abstract
The invention relates to a novel adjusting device for fused mass mixing degree, in particular to a door type fused mass adjusting device of a continuous mixing extruding granulating set. The adjusting device mainly consists of a lower door body and an upper door body; the upper door body and the lower door body are respectively connected with an opening-closing drive device; the drive device drives the upper door body and the lower door body to simultaneously move to the same direction or move oppositely. The device of the invention is matched with the continuous mixing extruding granulating set for using and can be mounted between two sections of machine cylinders vertically or in a certain angle. The control on the opening and closing as well as the opening and closing degree of the door bodies is achieved by the principle that the upper door body and the lower door body which are symmetrically arranged simultaneously move to the same direction or oppositely to change the passing-through area of the materials; thereby changing the mixing degree of a mixing system. The device of the invention has the advantages that the mechanical structure is simple and compact, the processing cost and the manufacture cost are low, the installation and the maintenance are convenient as well as adjustment and detection are convenient; cooling water is accessed into the door bodies to cool the fused mass, thus realizing self seal of the fused mass; the seal is reliable and impurities are reduced.
Description
One. technical field
The present invention relates to a kind of novel melt compounded degree adjusting device.
Two. background technology
Continuous mixing extruder grain unit is one of most important equipment of petrochemical industry ethylene project.Such extruder had both had the forced conveyance plasticizing capacity of traditional screw extruder, had had both the extremely strong mixing ability of rubber plastic banbury again.And melt compounded degree adjusting device is one of indispensable critical component of mixing extrusion pelleting machine set.Its main effect is to control mixing degree according to the material of the different trades mark and output, the control temperature of charge.Structure was as shown in Figure 1 arranged in the past: snap ring is set, changes the gap of screw rod 11 and machine barrel 12,, thereby play the effect that mixing degree is regulated in the unit with the extrusion pressure and the mixing time of adjusting screw(rod) by moving forward and backward of machine barrel on screw rod.But this kind structure is because moving member is whole machine barrel, thus with regard to existing problems such as mechanism is huge, design and manufacture cost height, wretched insufficiency be adjust with detect also inconvenient.
Three. summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of gate-type melt mass adjusting device of mixing extrusion pelleting machine set is provided, simple in structure, compact, the processing and manufacturing cost is low, convenient for installation and maintenance and adjustment and easy to detect, sealing is reliable.
The technical scheme that the present invention is adopted for achieving the above object is: the gate-type melt mass adjusting device of mixing extrusion pelleting machine set; mainly constitute by an Xiamen body and the body of calling; to the doorstep body is connected folding driving mechanism respectively with the Xiamen body, and drive unit drives goes up the Xiamen body simultaneously in opposite directions or deviate from motion.
Described folding driving mechanism is that left and right thread bush is equipped with at turning cylinder two ends, and left and right thread bush is connected with the Xiamen body with the body of calling.
The fixedly connected traveller of described Xiamen body, traveller and connecting rod are slidingly connected, fixedly connected guide plate one end on the connecting rod, the guide plate other end is fixedlyed connected with the right-hand thread cover; Body is directly fixedlyed connected with the left-hand thread cover to the doorstep.
Described body to the doorstep carries out wear-resisting, anti-corrosion processing with the surface that the Xiamen body contacts with material.
Described door body is provided with coolant flow channel, and logical cooling medium cool stream forms the melt self sealss through the melt to this in the runner.
The nitrogen of the external side-blown certain pressure of described door carries out the material anti-oxidation protection.
On the described door body opening and closing detector is housed, it can connect an axle that moves up and down together along with the door body for the end of connecting rod, and axle head directly reaches the outside of the fixed head (6) of the top, and fixed head is fixed a scale on (6), fixes a pointer on spool.
The supporting use of apparatus of the present invention and mixing extrusion pelleting machine set can vertical or angled being installed between two sections machine barrels.The upper and lower door body that utilizes symmetric arrangement is realized the control of a body folding and folding degree size simultaneously in opposite directions or deviate from mobile principle, changes the area that material passes through, thereby changes the mixing degree of mixing system.Have outstanding feature compared with similar products, frame for movement is simple, compact, and the processing and manufacturing cost is low, and logical cooling water carries out the melt cooling in convenient for installation and maintenance and adjustment and easy to detect, the door body, realizes the melt self sealss, and sealing is reliable and reduce impurity.This device can be widely used in the mixing extrusion system of thermoplasticity or high viscosity or plaster material, and runner is level and smooth, stable drive, accurate positioning, sealing are reliable.The present invention is particluarly suitable for using in the birotor dual-gripper continuous pugging extruder.
Four, description of drawings:
Fig. 1 is traditional melt mass adjusting device structural representation.
Fig. 2 is a structural representation of the present invention.
Five, the specific embodiment:
The gate-type melt mass adjusting device of continuous mixing extruder grain unit as shown in Figure 1, mainly constitute by an Xiamen body 1 and 2 bodies of calling, body carries out wear-resisting with the surface that the Xiamen body contacts with material to the doorstep, anti-corrosion processing, body is connected folding driving mechanism respectively with the Xiamen body to the doorstep, folding driving mechanism is that left-hand thread cover 9 and right-hand thread cover 8 are equipped with in turning cylinder 7 two ends, realize in opposite directions or deviate from mobile, body is directly fixedlyed connected with the left-hand thread cover to the doorstep, the fixedly connected traveller 3 of Xiamen body, traveller and connecting rod 4 are slidingly connected, fixedly connected guide plate 5 one ends on the connecting rod, the guide plate other end is fixedlyed connected with the right-hand thread cover; In the upper and lower door body coolant flow channel 10 is set respectively, logical water quench this melt of flowing through forms the melt self sealss in the runner, and the nitrogen of the external side-blown certain pressure of door carries out the material anti-oxidation protection.
In addition in order to detect mixing degree in real time, on the door body opening and closing detector (not drawing among the figure) is housed, the axle that it moves up and down along with the door body together for end connection one of connecting rod, axle head directly reaches the outside of the fixed head (6) of the top, fixed head is fixed a scale on (6), fix a pointer on the axle, carry out pointer and detect.
During work, by external force turning cylinder (7) is rotated, the right-hand thread cover (8) that drives the top moves down, and then guide plate (5), connecting rod (4), traveller (3) that drive is connected with the right-hand thread cover reach the Xiamen body (1) that is connected with traveller (3) and move down; Simultaneously turning cylinder (7) the left-hand thread cover (9) that drives the below moves up, and then the body (2) of calling that drive is connected with left-hand thread cover (9) moves up, and upper and lower body opened.Oppositely then upper and lower door body closure.The gap value of realizing rotor and machine barrel changes, thereby has changed the compactedness of rotor mixing section and the throughput of fused materials.The feeding capacity of different melt index resins what and material can be easy to change by the time of machine barrel thereupon, thereby made unit can adapt to different resins, temperature and output requirement.
