Description

With the device of gas treatment bulk product, be specially adapted to the aerial cooler of feed block

The present invention relates to a kind of device, be particularly related to a kind of cooler that is used for feed block with the gas treatment bulk product, this device has a container, a processed goods feedway and a processing gas storage collection chamber are arranged at the top of container, then have one to handle the ventilative discharge device of gas in its underpart.

Holland prospectus NL-OS 7908335 illustrate a kind of like this can be in gaseous exchange the device of processing product.Processed goods is to carry out on whole plane by means of a framework that goes and back running by discharging in the container, framework is equipped with two grids that are configured to be perpendicular to one another and separate, each grid is made up of wide and flat landscape configuration section bar, so its discharge-channel is narrow.The passage of two grids is opposed, so the discharge framework just produces a discharge process when doing motion.For making processed goods be difficult for being stuck on the section bar of Under The Grille when the discharge, just be necessary between two motion grids, to be provided with the 3rd hard-wired grid, its cross member is as the scraper component of Under The Grille.Therefore the structure more complicated of discharge device, and it is not own emptying.On the whole cross section of container, also some problems can be proposed aspect the distribution of processed goods.

This task of device solves according to invention is, makes the processed goods on the whole cross section of container reach automatic distribution by means of a kind of simple device, and simultaneously all processed goods can emptying and form and pile up.When conducting a survey, discharge device can be taken apart easily, therefore also just is easy near inner face.

This device according to invention is characterized in that, discharge device has the ventilative base plate of a taper, make it be provided with up pinnacle, and the ventilative base plate of taper moves by a vibration machine with certain vibration, its main direction of motion is level, preferably make a whirling vibration have slight flip-flop movement, and when processed goods discharge circumferential weld was open, conical bottom board was outwards outstanding in the bottom of container wallboard around the conical bottom board vertical axis.

As long as processed goods is carried to the pinnacle of ventilative base plate direction, it is just automatically uniform on all directions.Because this good distribution, the input body of regulating the flow of vital energy from the beginning just, this has just improved discharge rate, and feed (when container is not filled) not for a long time, processing procedure also is guaranteed.

If ventilative base plate is fixed on the preferably downward conical discharge base plate, this structure is just simple especially, this moment, the conical discharge base plate was provided with a center discharge gate, the processed goods of conical bottom board edge can be transferred on the discharge base plate, between the outward flange of ventilative base plate and discharge base plate, constitute an annular air inlet simultaneously.It is well that this air intake is set, and by plate washer is installed, just can make it be reduced to desired size easily when needed.It is very favourable vibration machine being fixed on the discharge base plate in addition, it can be supported on the movable support, preferably is bearing on the rubber bolster.

If at the lower limb of container wallboard the annular quantitative valve of an adjustment height is installed, the discharge rate of processed goods just can be adjusted accurately, and its height with respect to the base plate of breathing freely has determined to discharge the cross section of passing through of processed goods.In order to improve quantitative accuracy, available oriented device or support make quantitative valve make spiralling.Can make a kind of like this device: this moment, guider was made up of the oblique rail that is distributed on the quantitative valve periphery, and tiltedly rail then is bearing on the roller that is equipped with on the container wallboard, has a rotation transmission device simultaneously, preferably an air rammer.

If quantitative valve is less around the ventilative outer peripheral interval of base plate, its lower limb then is provided with some breach as the processed goods passage, just obtains significant superiority.Even so ventilative back plate vibration still might suppress the discharge process fully by means of quantitative valve.What be different from an equal and quantitative valve lower limb is that these breach can reduce discharge length widely, for example can reduce to 1/4th of container perimeter.Thereby quantitative accuracy is greatly improved once more, and might accurately control little discharge rate.For container is emptied completely, can place quantitative valve than the highland, just emptying on whole periphery of residue like this.

In order to realize automatic running, illustrated an extremely sensitive element can be set in container, its process adjustment or control action are on the transmission device of quantitative valve, also act on the switching on and off on the device of vibration machine, so just can make continuous or discontinuous container discharge process selectively.

Feeding device can have stacked tilting slide plate, and they have determined that the conveying of processed goods is along a zigzag route, and the forcing press that for this reason is provided with can be bled by storage collection chamber.

In order to obtain enough pressurization and air extracting, but also not because of compressor forms short circulation downwards, the resistance of bleeding shows should be more than 5: 1 with the ratio of the air mass flow of bleeding by the air mass flow of processed goods, preferably 8: 1.The change that guarantees air mass flow in the feeding device does not whereby produce big influence to the air mass flow by processed goods, thereby cooling effect is not had big influence yet.

Accompanying drawing summarily shows a kind of structural shape as the invention example, that is to say:

Fig. 1 represents a vertical section by container and discharge device axis;

Fig. 2 represents the plane taking its container away and take its ventilative base plate away;

The wallboard 10 of piece material cooler vessel 11 is equipped with a flange 12, and it helps to strengthen and be used for container 11 is bearing on the bearing support 13.Bearing support 13 is formed by being configured to a tetragonal beam 15, and these beams are then supported by leg 16.

A feeding device 17 is configured in the top 18 of piece material cooler.Feeding device has an inlet 19, disposes tilting slide plate 20-23 in its lower section, with the vertical wallboard 24 of a guiding processed goods.A processing air storage collection chamber 25 that is made of top 18 joins by an air outlet 26 and a unshowned air exhauster.

One has the ventilative base plate 29 on pinnacle 30 up, is fixed on the conical discharge base plate 32 down by supporting member 31, and the discharge base plate then is provided with a center discharge gate 33.Ventilative base plate 29 should be made up of a perforated plate, and its aperture should be less than the size of feed block, and for example having the aperture is 3 millimeters.

Discharge base plate 32 is equipped with an outward flange 34, and flange bearing is on the rubber bolster 35 as active supporting piece, and the rubber bolster then transfers to support by the support 36 that is fixed on the leg 16.Two vibration machines 37 are housed on the discharge base plate 32, for example have the uneven weight of rotating around vertical axis.Because vibration machine 37 is symmetrically arranged and synchronous, if on discharge base plate 32, thereby on ventilative conical bottom board 29, form a whirling vibration around the conical bottom board vertical axis by supporting member 31, like this for each point of discharge device 29,32 just produced one have slight flip-flop movement, be the direction of motion of level basically.A kind of like this transmission device with same support is known by american documentation literature US-PS3257040 and 3261592.Also can use cone rubber sleeve, pivoting support and similarity piece as supporting member without the rubber bolster, also might settle an independent vibration machine in the centre.

On the lower limb of the wallboard 10 of container 11, be provided with the annular quantitative valve 38 of an adjustment height.Just as seen from Figure 3, under the open situation in the annular discharge slit 39 of processed goods, ventilative conical bottom board 29 is outwards outstanding below wallboard 10.Constitute an annular air inlet 40 between the opposite side of the outward flange of ventilative base plate 29 or a side of annular quantitative valve 38 and discharge base plate 32.

Annular quantitative valve 38 centers on ventilative conical bottom board 29 with small spacing.Its peripheral diverse location of valve is provided with bearing plate 43, then is fixed with guide rail 44 on the bearing plate.Guide rail 44 is supported on the bogie wheel 45, and bogie wheel is placed on the axle of being fixed on the wallboard 10 46 rotationally.For the centering of annular quantitative valve 38, guide rail 44 is provided with lug, nib 47, and lug, nib then protrudes in the groove 48 of bogie wheel 45.On beam 15, be hinged with the cylinder 50 of a cylinder-piston apparatus therein, 51 in the piston of device acts on the lug 52 of annular quantitative valve 38.According to the direction of motion of piston 51, guide rail rotates to the right or left (Fig. 4), and makes annular quantitative valve 38 by guide rail 44 be configured in rotatable bogie wheel 45 actings in conjunction on the fixed position, does spiral motion and raises or avale.The lower limb 54 of annular quantitative valve 38 is provided with some and is distributed in breach 55 on the periphery.Should get the 10%-50% of annular discharge valve 38 girths by the expection discharge rate with by the breach total length that institute's precision prescribed decides, preferably 15%-40% particularly 25%.

Advantageously a unshowned extremely sensitive element can be installed in container 11.Thereby its control cylinder piston apparatus 50,51 is also just controlled the outer peripheral height of annular quantitative valve 38 with respect to ventilative conical bottom board 29, to determine to discharge the cross section of passing through of processed goods.With same control,, the transmission device of vibration machine 37 is disconnected if annular quantitative valve 38 is closed.

Its function is as follows: in the shown device situation, container 11 is that empty, annular valve 38 is closed discharge slit 39.Vibration machine 37 disconnects.After this processed goods that will handle is constantly imported by inlet 19, and flows downward through slide plate 20-23 with the speed of being braked.Vertical wallboard 24 deflects on the direction on pinnacle 30 of the ventilative base plate 29 of taper processed goods, from the pinnacle 30, processed goods is distributed on all directions, up to 39 places, discharge slit.Make ventilative base plate 29 be covered and connect air exhauster by one deck processed goods soon therefrom.Extraneous air is drawn in the air exhauster through air outlet 26 through annular air inlet 40, ventilative base plate 29, processed goods and storage collection chamber 25.The processed goods that flows through slide plate 20-23 produces a lockage effect of satisfying the coherent relation of general serial connection drainage pipeline.Otherwise, a special gate also can be installed in the front of inlet 19.When the charging of container 11 reached the requirement degree, extremely sensitive element was just connected pneumatic cylinder and piston apparatus 50,51, is made annular quantitative valve 38 to right rotation (Fig. 4).Like this, guide rail 44 from but full annular quantitative valve 38 just be lifted by bogie wheel 45, cause breach 55 open one by cross section, processed goods then is discharged from.Annular quantitative valve 38 can be regulated by control device, and its discharge rate and quantity delivered are equated.If discharge occurs on the whole periphery, because discharge length reduces because of jagged 55, can adjust withdrawal rate by 38 1 existing moving both vertically of annular quantitative valve, for example variation is very little in this case, therefore just can reach very big precision.But if make container 11 whole emptyings, annular quantitative valve 38 can be brought up to and make its lower limb 54 reach the ventilative base plate 29 outer peripheral tops of taper, and open whole discharges slit 39.Make all emptyings of container 11 therefrom.
