Abstract

The utility model discloses a double-filtration double-roller crushing machine, which aims at providing a crushing and stirring device that can save energy and effort and has good crushing effect and strong kneading force. The technical scheme has the main points that a plurality of bulges and recesses arranged alternately are respectively arranged on the peripheries of the outer edges of two rollers arranged in parallel; when in the operation of the two rollers, the bulges correspond to the recesses; filter grid trays that can shift inside and outside are arranged at the inlets of the recesses; and pistons that can move up and down are arranged in the inner chambers of the recesses. The two rollers run inwards synchronously to pull down raw materials and are extruded to lead the raw materials to be higher than the filter grid tray from outside to inside and enter into a cavity; when the two rollers runs to the lower dead point, the pistons moves upwards to lead the raw materials to be higher than the filter grid tray from inside to outside again and fall down onto a conveying belt, and then the raw materials are sent to the next procedure.

Description

Double filtering type pair roller Material disintegrator

Technical field the utility model relates to and is used for a kind of machine of comminuted starting materials, and particularly brick-tile industry is used for raw material is done a kind of plant equipment that prior processing is handled.

The approximate way that background technology is traditional be by two relatively the roller installed of level mutually inwardly in the rotation promptly one for turning left one for turning right raw material toward drop-down, owing on roller, be drilled with a plurality of holes, raw material is clamped the back and entered two roller inner chambers in extruding, the raw material that protrudes from the inner chamber hole is installed on the machine other end clear material scraper plate that stretches into roller inside of encorbelmenting by an end and scrapes, and falls into the next ribbon conveyer through two discharging opening and is sent to next procedure.

Because brick and tile producer great majority select for use clay to do raw material, contain stone in the raw material unavoidably, tree root and other, be difficult to broken hard thing, two rollers are arranged to one promptly can only rotate for fixed for this reason in position, one is on-streamly can back out certain size when running into hard thing for oscillating-type, both differences structurally are that the bearing block of swinging roller is mounted in Bai Bishang, when stone or other can not broken hard material enter the roller workspace, the reaction force of material is during greater than the horizontal applied force of the machine normal operating conditions tensioning apparatus of preset, then promote the swing roller, make swing arm around rotating the center steering certain angle, spring in the nervous device is compressed simultaneously to make and causes two rollers apart from increase, hard material falls into the next scrap web from the gap that increases and is excluded, foreign material are excluded the former compressed spring in back and stretch recovery immediately, and roller recovers operate as normal gap and operating pressure thus.

Although traditional filter formula twin rollers possesses the function of particle and homogenize, there is big energy-consuming in it, pressure is little and mix and stir deficiencies such as effect is not ideal enough.

Summary of the invention the utility model discloses that a kind of energy consumption is low, and the particle effect is good, and the double filtering type pair roller Material disintegrator that kneading power is strong is achieved by the following technical solutions.

Go up with equidistant protruding position and the recess of being provided with at the contour (360 °) of same roller, convex-concave position each other alternately promptly one protruding one recessed from arrangement, and install in the porch of recess some screen bars be combined into one can inside and outside slippage the filtration screen, the boring of the two ends of each piece screen bar and with spring or elastic cord by hole with its Colaesce, and between lath and the lath by spring location with separate certain size, because spring or elastic cord can extend and shorten, two rollers each other with protruding position to recess on-stream with raw material leave behind in extruding, make its surmount lath be broken with cut apart after enter in the relative cavity, filtering the journey size that promptly is shifted of walking of the inside and outside displacement of screen is controlled by rib before and after inside and outside set each one in cavity porch, what raw material entered that cavity leans on is the on-stream formed extruding forces of two rollers, entering to have discharge, what discharge was leaned on is that the piston that can be shifted up and down all is installed in each cavity, when each recess is on-stream when being positioned at lowest order, piston (roller center for down outer rim contour be last) in rising pushes away raw material to be crossed the grating plate and falls into and seen off on the next conveyer belt, finishes an acting circulation.

In order to realize that raw material enters cavity is coarse crushing, discharges cavity and is in small, broken bits and inside and outside each one the front and back rib radian that filters the screen place will be installed to make different be that the inner retaining side radius of curvature is little, and outer rib radius of curvature is big.Each the root screen bar that filters when not turning round in the screen is arranged in a straight line under the effect of spring or elastic cord, hence one can see that this moment adjacent every screen bar distance be the gap on roller for inside and outside unanimity, during running in the extruding of two rollers during toward interior (descend) displacement outside its gap little in greatly, make raw material be easy to surmount and promptly be not subjected to jam, in piston rises extruding outward (on) during displacement, its gap is inner small and outside big, raw material is convenient to by (raw material is from outward interior), according to what of the size of roller and cavity, two rollers are mutually by holding raw material tens in several cavitys of inboard that paste, hundreds of is to several thousand kilograms, these weight all are positioned at the inboard of roller and impel the inside and outside both sides of roller weight to differ, equaling thus provides tens for its rotation, short its rotation of the extra power of hundreds of or several thousand kilograms, thus realize the purpose of energy and labour saving.

Two roller run-in synchronism is that the gear by two structure unanimities is installed in the same termination of each roller respectively and is meshing with each other and realizes, the lifting of piston be rely on the next pole and travelling wheel on respective track slippage and follow roller run-in synchronism and finish.The main shafts at such two on-stream its centers of roller that driven by power are fixed, and being installed on the main shaft for the next track of walking wheel slip of piston is fixed too.Its kind of drive need only be meshing with each other transmission just with being installed in pinion on the speed reducer output shaft and the gear on one of them roller, belt pulley certainly is set borrows belt transmission.

The beneficial effects of the utility model are summarized as follows:

One, energy and labour saving.Its energy-conservation factor mainly is by the gravity of raw material, the inner chamber that raw material is pressed into the roller recess to by piston in rising with its release, it is walked journey and is less than 180 °, and the initial place of entering of raw material is positioned at the roller highest order with down to above the horizon, raw material is released fully at the roller lowest order, the input and output material position of two rollers is all on close mutually inboard sustained height simultaneously, upperly constantly be pushed into, the nextly constantly be discharged from, according to type size and concavo-convex position how much, its inboard of roller in the running on contour, account for often have in 120 ° the angle tens of, hundreds of or thousands of kilograms raw material, its gravity role is that roller is inboard toward pressing down short its rotation, has reduced power consumption thus.

Two, the effect of particle and homogenizing is good and efficient is high.With traditional method comparatively speaking, change twice extruding into by once pushing, and can advance the displacement size of filtering screen among the row according to the technological requirement adjustment, thereby obtain the width size that twice raw material in front and back advances to arrange passage, charging is coarse crushing, discharge is in small, broken bits, be that its gap of filter that raw material is passed through when being pressed into cavity is pushed out the filter gap that cavity passes through greater than raw material, although turnover all is to carry out on same filter, there is the branch of width in the gap but because the arc camber that its displacement size difference causes each screen bar (outwards or inwardly extruding put in place) when end-of-shift to be arranged is different, inwardly push its maximum camber that puts in place and be no more than 180 °, outwards extruding puts minimum camber in place more than 0 °, it is just wide more that camber is bigger than on the filter plate gap between each screen bar more, and raw material from inside to outside surmounts filter again by filter from outside to inside and equals the merit that a machine has been made two machines in the running.
