Abstract
The invention discloses a simple non-clogging vacuum chamber, and aims at providing the vacuum chamber which is simple in structure and low in cost and will not cause clogging when running for a long time. According to the technical scheme, the simple non-clogging vacuum chamber is characterized in that a sealed circular cover is additionally arranged on the outer edge of a cylinder cover of an extruder in a certain spaced manner, and in other words, certain space is reserved between the outer edge of the cylinder cover and the circular cover; a vertical or front-back continuous spiral blade is divided, and a filtering grating plate is additionally arranged at the divided position; and with the filtering grating plate as the boundary, the diameter of the portion, behind or above the filtering grating plate, of the spiral blade is small, and the diameter of the portion, in front of or below the filtering grating plate, of the spiral blade is large. On the basis of the acting principle, raw materials are pushed forwards or downwards through the running spiral blade and become tight from loose after going beyond the filtering grating plate due to the fact that the passageway cross section is reduced, and therefore air is prevented from entering the materials; and due to the fact that the displacement speed of the raw materials is increased after the raw materials go beyond the filtering grating plate, the condition that the raw materials clog the vacuum chamber when delayed does not exist any more .
Description
Technical field
The present invention relates to the vacuum chamber of vacuum-extruder for extracting air, is more definitely more particularly for the air in raw material being extracted the anti-inlet duct of set one by vavuum pump.
Background technology
For the extruser of shaping tile blank tire, in order to make mold more tight, current one of effective method is the most extracted by air contained in loose raw material by vavuum pump is on-stream, traditional way and prior art be as shown in Figure 1 to Figure 3: the reductor 12 driven by higher level's motor 11 and shaft 3 and the stirring blade 4 be arranged on shaft and higher level's helical blade 24, two, left and right (only illustrating single in figure) taper sheath 23 and scraper cutter 22 is also had together to operate, because double stirring blade and axle exist certain oblique angle, each in extroversion and inwardly more down in run-in synchronism at double joint shaft (also promising single), namely the raw material entered from hopper 13 in tank diameter 10 constantly pushes forward for dextrorotation for left-handed one by one, due to little front ambassador's passage after the taper sheath 23 of two, left and right from large to small, thus to being that loose raw material applies extruding and becomes closely originally, prevent entering of air thus, to fragment be divided into fall into vacuum chamber 14 by raw material closely through scraper cutter 22 again, because the air in vacuum chamber is extracted out from draft tube 16 by the effect of vavuum pump (not shown).The reductor 25 driven by subordinate's motor (not shown) connects and holding pad axle 9 together operates with the helical blade 2 be arranged on main shaft with the holding pad 6 be arranged on its axle and subordinate's main shaft 1, on-stream pressure by holding pad by the raw material falling into vacuum chamber enters extruder cylinder sleeve 7, by the helical blade 2 in running, constantly by it, down or forward (vertical dress is down, paperback is forward) push, short its surmounts its section and is squeezed into compact base bar much smaller than the machine mouth 8 of epimere or back segment cylinder sleeve section, be sent to next procedure again and be divided into the adobe of one piece of block monolithic or unbaked tile.
Base bar can be made after air in raw material is extracted to combine tightr, be well suited for the raw material that corresponding plasticity is lower, its weak point is: because the tank diameter inwall in running and taper sheath and helical blade are all vulnerable part, particularly taper sheath had both been subject to the friction of raw material in reach, be subject to again the friction with raw material in rotation, once its passage of wear and tear overrun is broadened by narrow, not only feed quantity strengthens, and is difficult to stop that entering of back air makes vacuum chamber ineffective; The corresponding minimizing of its extrusion capacity after simultaneously subordinate's helical blade wearing and tearing, one increases one subtracts and certainly will form raw material and to be detained and blocked at vacuum chamber, and because vacuum chamber blocking is full, tight makes vavuum pump ineffective to the lighter, and severe one door for vacuum chamber is forced to shutdown process by racking.There is the more high disadvantage of manufacturing cost because of complex structure in addition.
Summary of the invention
The present invention, for overcoming above-mentioned deficiency, aims to provide a kind of vacuum chamber that the simple also long time running of a kind of structure can not result in blockage, is achieved by the following technical solutions.
One deck and outer wall of cylinder jachet sealing shape spaced apart from each other round jacket is installed additional beyond extruder cylinder sleeve outer rim contour, namely by interior be outer wall of cylinder jachet, outward for the space between outer casing inner wall becomes a vacuum chamber, and will up and down or (vertical dress is upper and lower in front and back, paperback is front and back) continuously helical blade disconnection, and at gap, filtration screen is installed, foundation material performance and its filtration screen of technological requirement can be single tracks, more than two pass or two pass, when this grating plate be two pass or multiple tracks time, the lower end of its vacuum chamber or top, front end surmount the most lower or the most front one filter grid plate installation position.Resistance is larger because section is too small to tackle its machine mouth of extruder if desired, with filter screen for helical blade is made into by boundary up-small and down-big or rear little before large, and filter the helical blade outer rim initiating terminal of screen stretch in vacuum chamber by surmounting, its objective is just in case have a small amount of raw material to enter in vacuum chamber can and at present before or release forward.One air intake duct break-through vacuum chamber is installed on the coat be connected with vavuum pump.
Its acting principle is: because the existence of filtering screen makes raw material shift paths greatly reduce, thus certain resistance is applied with to raw material, replace original concentric reducer taper sheath thus, raw material is made to become closely from loose, not only prevent entering of air, and raw material is carried out round segmentation and roll, the quantity of filtering screen is set according to material performance and technological requirement, thus higher level can be saved stir operation; Again due to filter screen under boundary or leading portion helical blade is greater than or back segment helical blade and extrusion capacity increases to some extent, filter screen and also there will not be because raw material is detained even if do not arrange and block vacuum chamber phenomenon.
Beneficial effect of the present invention is summarized as follows:
One is that structure is simple.Owing to there being the existence of the filtration screen of more than single track or two pass or two pass, helical blade is had to be separated by between every twice, helical blade role implements to push, roll and stir to raw material, filtering screen role is split and apply certain resistance to make air be difficult to pass through to raw material, thus the mixer that higher level is made up of shaft and tank diameter and the accessory such as stirring blade and taper sheath can be saved, and for driving the spare and accessory parts such as power and reductor of shaft;
Two is without blocking.Due to filter screen for boundary up and down or claim before and after its size of helical blade determine with material performance and technological requirement, up and down or anteroposterior dimension equal or lower large little or pre-large post-small, can not cause with raw material and block vacuum chamber because of delay and be as the criterion, particularly when extruder be vertical installation namely from top to bottom for vertically extrude time, because of gravity effect and have its raw material of room below and just lose the condition up entering vacuum chamber, because this eliminating the deficiency because vacuum chamber is blocked or damages and shut down;
Three is more durable.Be staticly not rotate owing to filtering screen, and raw material entrance in surmounting is less than outlet and coefficient of friction is low.On its vacuum chamber or back plane be connected and fixed by screw rod and nut and cylinder sleeve, do not need to arrange for picking up the dodge gate repaiied and more durable;
Four is be difficult to gas in vacuum chamber enter.Its reason is that raw material is surmounting in filtration screen process for pass through from the little round gap of multiple isolation, thus be extruded tighter, although air starvation formation suction is also difficult to be suctioned through in vacuum chamber, the method for the distance strengthened between helical blade end and filtration screen can also be selected still more to make air barrier thicken to prevent from suctioning through.
