Description
The present invention relates to a kind of manufacture method of granular glass material, mean a kind of manufacture method especially with the granular glass material on slick and sly surface.
At present environmental consciousness is surging; the material recovery of various discarded objects has become the important topic that resource reclaims; wherein; cullet is exactly a kind of material of can holomorphosis and utilizing; with Taiwan is example; the annual at present cullet that all produces huge amount, these cullet are if can effectively be recycled, and then the efficient to environmental protection and resources untilization all has great help.Yet, glass incinerates to be difficult for melting and becomes ash to the greatest extent, also can't biologically decompose, but because glass property and sandstone are very approaching, thus have many with the glass recycling in building building materials such as ceramic tile, floor tile, light weight aggregate or building materials, road pavement, artificial marble or as the raw-material example of glassware.
In the cullet treatment process, the attribute that must originate according to cullet earlier carries out color separation processing, and this is because the unicity that the glass particle material of last gained must have color possesses higher economic value just now.The recycling of these cullet, its processing mode is general all after preliminary classification and color separation are carried out in the cullet source, again impurity (iron, aluminium, pottery etc.) is wherein removed, then, it is pulverized and cleaning, and, can obtain the cullet particle that can utilize a little with preliminary sharp angle blunt, this is the most basic cullet processing procedure, its main points only are to classify, color separation, with the process of cleaning.In addition,, after preliminary treatment, can impose the mode of traditional kiln fusion again, that is, after the cullet that reclaims smashed to pieces, carry out preliminary classification and color separation processing earlier for allowing the cullet that reclaims can enlarge its value as far as possible, again with it with high-temperature digestion.This type of existing processing method nothing more than later the cullet piece of will classifying via heating, mix or technology such as rub works, cool off and smash to pieces.These existing technologies can be summarized as follows:
Heating is inserted the cullet piece in the melting stove, is heated to reach the above high temperature of thousand degree Celsius approximately, so that glass blocks becomes the glass paste of a fluid melting shape.
Mix or rub work, will be by the slurry temperature under the high temperature shape, make the glass blocks of inserting to be fused into flow-like fast, at this moment, can insert the glass blocks of different colours according to required finished color, follow, and the glass paste that mixed flow mixes is further merged, and carry out irregular rubbing fast and do and stirring, so that kneading becomes semi-harden state.
Xu Leng is placed on the indoor of proper temperature with the glass after being shaped and cools off slowly, to prevent or to remove strain.
The frit that generally is used as industrial materials and building materials is that the form with bulk sells, so these also must be through the process of overmolding and cutting by the made glass raw material of cullet, last just be divided into different sizes and color sells or, perhaps, cooperate the purposes of glass, also these glass can be smashed to pieces branch and make thin piece or granular small blocks.
In above-mentioned existing method, use the back system processing mode of traditional kiln fusion often to make that the cost recovery of cullet is too high, because these smelting process not only step are complicated and consuming time, and the energy of its consumption and equipment cost are also very high, so make glass material with respect to the raw material that uses non-cullet, use the made glass material of cullet on price, can't possess sufficient competitiveness.If reduce the cost that cullet reclaims back technology, and follow-up smelting process is saved, then the granular glass material of its gained often has very sharp acute angle, very easily causes user's incised wound, thus in application also very impracticable and safety.
So, need badly at this situation and propose the back technology that a cullet that improves reclaims, so that can reach the highest goal that resource reclaims.The purpose of this invention is to provide a kind of manufacture method,, and can provide glass material after the practical recovery so that reduce cost recovery with the granular glass material on slick and sly surface.
For achieving the above object, the invention provides a kind of manufacture method with the granular glass material on slick and sly surface, its glass material that can the classification color separation is good, also go ahead of the rest preliminary treatment is further processed, in order to the resource reutilization that reclaims cullet, this method may further comprise the steps: (1) is tentatively pulverized into earlier glass particle with glass material; (2) tentatively remove the acute angle of glass particle with the vibrations and the mode of bump, wherein, glass particle system is mixed mutually with a Refractory blocks material with enough hardness, so as by its mutual collision the acute angle of each glass particle of passivation; (3) add a release agent among glass particle and will stir together, so as to separate each glass particle make its be unlikely in one of follow-up heating process, be stained with mutually sticking or molten mutually; (4) glass particle is carried out a heat treatment so that glass particle tentatively the acute angle of blunt can further shrink; And (5) will shrink the glass particle of acute angle air-dry with the hardness of Xu Leng with the tempered glass particle.
Utilize the treatment process of glass particle provided by the present invention, the cullet particle that reclaims can be removed acute angle effectively, so the cullet particle of gained can be used as purposes such as various building materials and process article fully, fully reaches the target that the cullet resource reclaims.And, adopt cullet treatment process provided by the present invention, the cullet treatment process that can give up traditional kiln fusion fully, so can greatly simplify the processing procedure of cullet, the cost of its processing also greatly reduces, greatly feasible so the recycling of cullet can conform with economy, the implementation that the resource that is highly advantageous to reclaims.
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described.In the accompanying drawing:

As shown in Figure 1, cullet method for making granules provided by the present invention refers to cullet is handled the further processing method of glass particle of gained afterwards in advance.Generally speaking, the cullet of recovery must be earlier through the processing of classification with color separation, the pre-process technology 1 that this cullet reclaims promptly as shown in Figure 1, for example, the recovery of these cullet source can be beverage bottle of picture tube glass or particular color or the like.These good cullet materials of color separation (as flat board, bottle bits or picture tube fragmentation etc.) of classifying through step 11 are big or small uneven piece of debris or fragment, further filtration impurity or the foreign material wherein in step 12 so still need, these impurity or foreign material mainly are metallics such as some wherein iron of mixing, aluminium or potsherd etc., then, in step 13, again with the further coarse crushingization in addition of the glass fragment of these bulks or fragment, with convenient follow-up processing, through behind the cleaning step 14, the cullet particle of gained can be carried out subsequent treatment.According to embodiments of the invention, one glass particle treatment process 2 promptly is by reclaiming the made glass particle of cullet after the above-mentioned pre-process technology 1 of process with these, further processed and finishing, so that can meet requirement as granular glass material.
As shown in Figure 1, in glass particle treatment process 2, at first, in step 21, glass particle preliminary pulverizing in addition with gained in the pre-process technology 1 is crushed to graininess or the block glass that diameter is about 1-12mm with these glass fragmentations roughly with a boulder crusher (Jaw Crusher).Then, in step 22, the material that the glass particle after these coarse crushings and a Refractory blocks are formed mixes mutually, and with one such as the machine of jarring machine by collision mutually and the sharp-pointed acute angle of each glass fragment of passivation.This is all to possess very sharp-pointed acute angle usually because of the glass particle by pre-process technology 1 gained, and its shape is uneven, the about 50-100mm of this Refractory blocks diameter also has enough hardness, it is with after pending glass particle fully mixes, can by with the mutual collision of glass particle with its acute angle blunt, so this step can be with pending glass particle size equalization tentatively in addition.Then, in step 23, with these glass particles that tentatively pulverize with vibrations mode (for example, utilize a jarring machine) screening different size glass particle, after processing through step 21 and 22, because the size decreases of glass particle, so help follow-up heat treatment, this be because of less its surface area of glass particle of size also less, so corresponding fusing point is also lower, so heat treated heating-up temperature promptly needn't be too high,, and cause the mutual bonding of each glass particle easily because too high heating-up temperature not only expends the energy.Then in step 23, then further glass particle is classified, and the good glass particle of will classifying inserts in the storage barrel, to treat follow-up processing according to conditions such as colors.
Then, in step 24, the glass particle of above gained is mixed release agent just like the calcining carclazyte, and at room temperature it is stirred in a mixer, its purpose is to utilize release agent can make the effect of the unlikely direct contact of each glass particle.In the present embodiment; employed glass particle stirs with the weight ratio of calcining carclazyte with 1: 1; and; under preferred condition, glass particle about gross weight 300kg and calcining carclazyte continuous stirring were reached more than 5 minutes, so that make the calcining carclazyte can fully be mixed between each glass particle; the purpose that it is not directly contacted mutually; thus, when carrying out the heat treatment of this step, can reduce the sticking mutually probability of each glass particle as far as possible.
Then, step 25 will with the in addition further heat treatment of calcining carclazyte well-mixed glass particle, in heated glass particle, fusing point is higher because its surface area is little at every position with sharp-pointed profile, so very easily melt because of heating, the comparatively slick and sly position of glass particle is because of the higher then unlikely fusing of fusing point, so can further shrink the acute angle of each glass particle and obtains the effect that makes glass particle have rounded profile.And, owing in step 24, glass particle has fully been mixed, so in the process of heating, unlikelyly cause being stained with sticking mutually or combining into another larger-size particle because of mutual melting of each glass particle because local temperature is too high with the calcining carclazyte.Yet nonetheless, the heating-up temperature of this step is still unsuitable too high, in the present embodiment, pending glass particle is carried in a spiral heating machine or induction heater, experimental result, the preferred temperature control of this spiral heating machine approximately can be divided into (600 ± 50), (850 ± 50), (1050 ± 50), (800 ± 50) ℃ four heated zones, be subjected to this glass particle system of heat treated to pass through this four temperature section continuously with the speed of 540 ± 50kg/hr, if it is too much to send into the amount of the glass particle in the spiral heating machine, then can influence the uniformity to its heating, the acute angle of glass particle promptly can't shrink fully, in addition, the total length of its heating had better not be less than below 4 meters, so that to be provided enough heat time heating times.After shrinking acute angle, the shrinkage degree of each glass particle is had nothing in common with each other, so formed granular size is also different, so, in step 26, then carry out secondary size selection with a jarring machine.In addition, before the size selection that carries out secondary, just the glass particle that comes out from the spiral heating machine also needs the course of conveying of elder generation through an insulation, and this process need moderately will just heat the glass particle that finishes and keep at a certain temperature, in order to avoid glass particle is because of the quenching fragmentation.
Then, in step 27, with glass particle with the rinsing machine cleaning of being washed by water, with remove previous technology institute admixture such as materials such as calcining carclazytes, this rinsing machine is about 40-50 ℃ warm water washing glass particle wherein with temperature.Then, in step 28, glass particle is carried out a hot blast do process with Xu Leng in a Xu Lenglu.In this hot blast was done process with Xu Leng, the temperature of Xu Lenglu need be higher than room temperature basically and be lower than the heat treatment temperature of step 25, experimental result, and in the present embodiment, the temperature of Xu Lenglu approximately maintains about 30 ℃.By this process, can further strengthen the hardness of heating back glass particle.So far, promptly finish a glass particle treatment process of present embodiment, then, send into these glass particles in the storage barrel and carry out follow-up packing and get final product.
Utilize the rearmounted treatment process of cullet particle provided by the present invention, cullet fragment or the fragment that reclaims can be processed into the glass particle that high industrial applicability is worth, and, its made glass particle all has very slick and sly surface and the standardized size of specification, so can meet industry, construction, and the demand of purposes such as technology fully.And, adopt cullet treatment process provided by the present invention, can give up the cullet treatment process that traditional kiln carries out in the fusion mode fully, so can greatly simplify the handling process of cullet, its processing cost also greatly reduces, therefore, also greatly promote the economic benefit that cullet reclaims, the implementation that the resource that is highly advantageous to reclaims.
Made glass particle raw material of the present invention can be widely used in every field, for example, aspect building materials, can be used for the about wall, indoor and outdoor ground of building, with asphalt surface etc.; Aspect gardening, can be applicable to the flower garden and make scape, carry etc. with basin; Other then can be applicable to the making of handicraft, with fish jar interior trim or the like.
