Abstract

The present invention is a kind of device of clearing up particle surface.Device such as cleaning sea sand surface.It includes a casing (1) that holds particle, and blade (2) and grinding stone (3) are housed in the casing, and above-mentioned blade and grinding stone can be done relative motion and adjacent to each other.

Description

The device of cleaning particle surface

The present invention relates to a kind of cleaning particle, as cast the device on husky surface.

Used various castings sand and the used stone sand of concrete industry of foundary industry often has unwanted material attached to its surface, has therefore just caused many difficulties hereinafter described.

Former sand its surface of being everlasting of casting usefulness is stained with clay, and this in use can hinder the discharge of gas.The salt grain is often adhered on the surface of sea sand, and good concrete brings adverse effect to give perfusion.It is relatively poor that the surface has former sand processability in husky mold forming of seamed edge.In addition, this class particle generally together uses with a kind of sticking compound, and the former sand after using can infringement be cast product as reusing.Therefore, now existing multiple in order to the cleaning particle, as the device on the surface of former sand and used sand.

For example, Japanese Utility Model SHOWA50-50808 discloses a kind of device, and it will be cast sand blasting by an air nozzle and go out, and makes it violent row collision and hits on the plate one, clears up husky surface with this.Another Japan Patent SHOWA57-109540 discloses a kind of device that has rotating vane, and sand is imported between rotating vane, utilizes the centrifugal force of blade to make the fierce mutually collision of the grains of sand to reach the purpose on cleaning surface.This patent also discloses a kind of device that has rotary box, and sand is packed into makes it mutual friction in the case.The usual means on another kind of cleaning grains of sand surface is to utilize the method for volatilization, i.e. resin and other materials of adhering to of burning surface.Also having a kind of usual means is with grains of sand surface attachments flush away by washing.

Yet above-mentioned several devices all have following defective.Sandblasting by the air nozzle makes it to collide device at a collision body, and its collision body wearing and tearing are very fast thereby shortened life-span of device.The device that has rotating vane is because the impact velocity of sand can cause a lot of sand and dust too soon.The sand device that rotary box makes it mutually friction of packing into is difficult to remove grains of sand seamed edge, and therefore moulding property can be not good when doing husky mould through the grains of sand so handled.By burning the device of husky surface resin and the volatilization of other analogs generally can not be removed grains of sand seamed edge, in combustion process, also can occur grains of sand burning simultaneously sometimes.It is little to nonhydratable material effect that the device of removing husky surface attachments is washed in utilization, can not remove grains of sand seamed edge.

Therefore, purpose of the present invention is exactly that a kind of device that can overcome the existing apparatus shortcoming will be provided, it effectively eliminating particle be the unnecessary attachment and the seamed edge on grains of sand surface.

For achieving the above object, the device of cleaning particle surface of the present invention includes the tank of the particle that is used for packing into, and a blade and a grinding stone are housed in the case.Device of the present invention is characterised in that blade and grinding stone can relative (promptly independently of each other) motions and adjacent to each other.

The performance and the effect of this device are as described below.

To pack in the case and put it between adjacent vanes and grinding stone such as the particle of the grains of sand.Because blade and grinding stone can rotate independently of each other, the blade that particle can be rotated is divided into many little parts and repeated collision grinding stone constantly.

Rely on above-mentioned functions, the particle in the casing of packing into can collide grinding stone effectively, and the unnecessary attachment material and the seamed edge of particle surface just can be eliminated.Simultaneously, by the relative velocity of adjustment blade and grinding stone, or pass through the working time of control device easily, the inhomogeneous attachment of particle surface can reach above-mentioned effect.Material under removing can take out from device by be connected a common dust catcher on device at an easy rate with seamed edge.

The most preferred embodiment of the device of cleaning particle surface of the present invention is with reference to the accompanying drawings in this explanation.

Fig. 1 is the part front section view of device, has embodied an embodiment of cleaning particle surface device of the present invention.

Fig. 2 is the perspective view of the separator in the separation chamber shown in Figure 1.

Fig. 3 is the part side sectional view of cleaning particle surface device shown in Figure 1.

Fig. 4 shows the situation that particle is just grinding with the grinding stone surface.

Fig. 5 is the part figure that shows another embodiment of cleaning particle surface device of the present invention.

The total of accompanying drawing 1 and 3 these devices of explanation, the device of this cleaning particle surface include a device body A basically, and a dust catcher 9 is used for surface attachments under grinding and the particle seamed edge under the collision are taken out from device body A.There is an outlet 10 to be connected at the topmost of device body A, under exporting, a separation chamber 11 arranged, be used for tiny foreign material are separated with particle with dust catcher 9.From the enlarged drawing of accompanying drawing 2, see, in separation chamber 11, separator can be installed.This separator includes two pairs of inwalls with the separation chamber and joins and flat board opposite one another 21,22, and the

pole

23,23 of two support plate 21,22.Dull and stereotyped 21,22 is vertically opposed mutually, forms a space therebetween, so that foreign material are shifted to outlet from the bottom thus.The advantage that this separator is installed is, the particle and the dust rotation that can enter dust catcher 9 raise, and heavier particle is fallen and makes light and little foreign material enter dust catcher 9 to continue at a high speed to rise.Here must notice that the used dust catcher of cleaning particle surface device of the present invention can be any centralized dust catcher.

A grinding stone 3 is arranged at the bottom of separation chamber 11, and it is by the many grinding flag 3a that embed rotating shaft 4,3a ... form, many blades 2,2 are installed in addition ... with grinding stone 3 in abutting connection with and be radial.Grinding stone 3 not necessarily is made up of the grinding flag of many ring-types, and a single cylinder gets final product, blade 2 also needn't by shown in Figure 3 like that with grinding stone 3 outer surfaces vertical packing into.Be exactly specifically blade 2 needn't with grinding stone 3 outer surface form right angles, and can constitute acute angle or obtuse angle.

Its rotating shaft is pointed in the bottom of blade 2, links to each other with grinding stone 3 and by helping plate 29 to be installed in the place near grinding stone 3 rather than the top of blade 2 grinding such as the fastener of pin member (not shown).Be in operation, when particle is divided into many little parts by blade 2 and rotates thereupon, particle moves between blade and with the surface collision of grinding stone 3, grinding the effect that helps plate 29 is to increase the effective collision rate on particle and grinding stone surface to strengthen grinding effect by the control translational speed.In addition, this grinding helps plate 29 also to help the rotation of stabilizer vane 2.That is to say that when blade 2 rotates at a high speed, so-called part grinding phenomenon can occur, i.e. the irregular rotation of blade has hindered the normal impingement of particle with the grinding stone surface, thereby cause the part of particle to grind.Grinding helps plate 29 can prevent this phenomenon effectively.Simultaneously, this grinding helps plate 29 can pass through to adjust the different parts adjusting of fastener and the far and near distance of grinding stone 3.

As shown in Figure 3, can connect an elastic component 24 of making by rubber or analog in the outer end of blade 2.This elastic component 24 has been filled the outer end of blade 2 and the space between casing 1 inwall.Its advantage is the grinding that has prevented this space.The external end head that can see blade 2 from Fig. 3 is by a predetermined angular bend.But this is not necessary, that is to say, external end head also can be straight, thereby has simplified processing of leaves.

The side of blade 2 has annular slab 6,6 on (the right among Fig. 1 and the left side), going barrel body of its whole formation.Therefore, form a space that links to each other with grinding stone 3 surfaces in 2 in each blade.Grinding stone 3 and blade 2 are coaxial, so that an identical axis of rotation is arranged.Grinding stone 3 is by motor 12 startings that are installed in device body bottom, and blade 2 is by another motor (not shown) starting that is installed in device body bottom.Many blades 2,2 are arranged below the going barrel body ..., two drum shaped body are by

roller

19,19, and 19,19 support respectively, and roller is installed in drum shaped body front and back (the left and right direction among Fig. 1) respectively.(only indicate two rollers before and after being installed among Fig. 1, for the sake of clarity, Fig. 3 does not show).

As mentioned above, because two different motor drive grinding stone 3 and blade 2 respectively, can make the rotation or with different speed rotations relatively of grinding stone and blade easily, thereby can strengthen grinding effect according to handled particle type.

Generally speaking, the means of abrasion of grinding stone 3 is preferably by carborundum, and aluminium and the material higher than handled pellet hardness constitute.

Respectively there is a balance adjustment plate 5 at the two ends of rotating shaft 4, can also can be used as holding screw by the balance plate that a balance weight is adjusted.The two ends of rotating shaft 4 link to each other with the falsework 17 of the casing 1 of supporting arrangement body A by supporting base 18.

With reference to Fig. 3, there is a particle inlet 8 side of separation chamber's 11 lower boxes 1, has one to be used for observing the observation panel that particle grinds situation and grinding stone surface loss at another side.Particle is divided into little part by each blade 2 after being packed into by inlet 8, enters the surface that casing 1 gathers and fall to grinding stone 3 then.Because grinding stone rotates with constant speed, the particle of one group of group just constantly falls, and the surface of grinding stone 3 just enters effective grinding, thereby particle is cleared up.

Fig. 4 shows that particle 14 surfaces of packing into are under these conditions just clearing up by collision grinding stone surface 13.Through the collision with grinding stone surface 13, particle 14 becomes sphere substantially, has removed foreign material 16.

Through the grinding of certain hour, particle 14 is taken out by the lid 25 of cylinder 26 controls and the outlet 15 of casing 1 bottom through one.Experimental results show that through there not being the spheroid that unnecessary attachment also can form no seamed edge on the particle surface of so handling substantially.

Device in the foregoing description designs by a batch working.But the present invention is not limited to this.For example, this device also can be made the device of continuous operation, promptly constantly from the one side of grinding stone 3 particle of packing into, and takes out particle from being positioned at the low slightly outlet of grinding stone another side.Here the backplate 27 that only needs will be contained under the observation panel 7 is removed and the lid 28 of connect box 1 is opened.At this moment backplate 27 closes once more, and device just can continuous operation.In addition, in order more effectively constantly to insert particle, cylindrical outer surface can also be made spiral male and fomale(M﹠F).

A simply constructed particle surface grinding attachment device also can be installed before inlet 8 simultaneously particle is carried out preliminary treatment.This attachment device can be the casing that inside has only rotating vane, makes particle friction mutually in case.Perhaps, be the casing that inside has only spin finishing stone, make particle in case, collide the surface of grinding stone.Carried out for two steps as stated above as particle and handle,, also can effectively particle surface be cleaned out in a short time even the adhesion of unnecessary additives is very tight.

Other embodiment:

Grinding stone 3 can be not and blade 2 coaxial installations, with the drum type body of common formation rotation, and can install along the lower inner wall of casing 1.Like this, or have only grinding stone 3 rotations, or have only blade 2 rotations, or both's rotation.That is to say that key is that grinding stone and blade can do relative motion.

In addition, can also grind betwixt by the particle of packing between two grinding stones.More more specifically, with reference to Fig. 5, another can be installed near the outer end of each blade 2 grind flag 3b.When operation, particle surface grinds between grinding flag 3b that rotates and the grinding flag 3c at lower box, thereby has more strengthened grinding effect.Here, the number of blade 2 can be one, also can be two or more.
