Abstract

The present invention provides a processing method for recycling weld bead slag, which includes a crushing step and a powdering step; in which the crushing step is to crush a weld bead slag plate into a plurality of weld bead slag blocks, making the volume of each weld bead slag block smaller than that of the weld bead slag plate; and the powdering step is used to grind the weld bead blocks into a plurality of weld bead slag powder. The efficacy of the present invention is that the crushing step and the powdering step are utilized to process the weld bead slag plate originally treated as waste into the weld bead slag powder, facilitating the weld bead slag powder to be applied to subsequent recycling operation like moisture absorption, soil modification, ground improvement, soil hardening, and being added into sludge to absorb water content therein and neutralize pH value of material, and into expanded cement and construction material, so as to increase the economical value and become more environmental friendly.

Description

201210710 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a waste disposal method, and more particularly to a method for treating bead slag reuse. [Prior Art]

In steel mills, steel and other operations. However, it is on the ground or the working slag sheet. There are many welding operations, such as welding steel into η 2 in the welding process towel, the solder will inevitably drip and condense on the table, the solder will be formed for a long time - the whole piece of welding, because welding is usually considered in the industry The slag plate contains heavy gold. This treatment of the weld slag plate is very troublesome. Usually, the ball slag plate is used. The stone step (1) directly adheres the weld bead adhered to the ground or the work table to the ground or the work table. Step (2) The ballast slag sheet is then transported to a legal waste disposal site for disposal, or the bead fish sheet is buried in the underground of the waste disposal site. Of course, it must also be paid to the waste disposal site. ''Therefore, the beading: 3⁄4 sheet of the subsequent treatment is not only economically profitable: it will increase the disposal cost of subsequent disposal or burial, and even save it at the same time, how to improve the above problems and improve its economy and the ring r's government has always been an important goal of the continuous efforts of the technical field. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide an economical and environmentally friendly method for treating 201210710 ball residue reuse. Yu Yu, the processing method of the re-use of the bead of the present invention, and a powdering step.匕a—The smashing step The shredding step cuts—the solder sheet material, so that the volume of each bead material is smaller than the slab. The pulverization step is used to grind the Tamao fishing block into a plurality of weld beads

Since the materials listed above are basically materials commonly used in daily life, and most of them are not toxic, the steel mills in the past think that the ballast slag sheet 8 contains heavy gold layers and may cause misuse of dangerous money. The test of the calender diffraction analysis and the aqua regia test confirmed that the bead slag sheet 8 is substantially non-toxic and therefore has an economically usable value. Referring to FIG. 4, the SEM crystal phase diagram of the bead slag sheet 8 can be seen from FIG. 4, the composition of the bead slag sheet 8 is not a complete and strong structure, and is integrated into a granular shape, and each is integrated. The particles have a lot of voids between each other' so there is no particular difficulty in the treatment of the shredding step 2 and the pulverizing step 4, so there is no need to use expensive, powerful shredders and pulverizing implements. In actual use, 'the water content in the bead crushed material 8n is very low' and a lot of holes are formed, 1 because it is a powder, the overall volume is large'. Therefore, the bead is broken 8] ! It has a strong moisture and impurity adsorption capacity. Referring to FIG. 5 and FIG. 2, a first preferred embodiment of the method for processing the bead stain reuse of the present invention is substantially similar to the first preferred embodiment of the present invention. It is that the method of treating the bead collapse re-processing includes a screening step 5' and an adding step 6. In the adding step 6, the bead slag powder 8U is added to a substrate (not shown). 201210710 In the preferred embodiment, in the preferred embodiment, the bead slag powder 811 is added to the soil and the soil, thereby changing the soil quality. It is of course also possible to add the Tan: C-side powder 811 to the sand and the cement or the asphalt, and mix the materials of the base layer, thereby improving the durability of the road surface. Of course, the T-road fishing material 8U can also be added to lime (oxidized (1), hearth powder (carbon 酉 妈) to enhance the overall moisture adsorption characteristics, or added to the water glass to change its visual effect. The substrate may also be a tea powder milled after the dried tea leaves are dried. By adding the tea powder powder to the bead slag powder 811, it is used to loosen the soil and increase the soil when the soil is modified. Nutrients, and can adjust the pH of the soil to facilitate the cultivation of the crop. In the preferred embodiment, the sieving step 5 is performed after the pulverization step 4 is performed, and is carried out by the No. 4 sieve The first sieving, and the bead slag powder 811 having a particle size larger than the No. 4 sieve is used for gradation or site improvement. The bead slag powder passing through the No. 4 sieve (aperture 4 75 mm) is further used. The second sieving is carried out with a No. 100 sieve, and the bead slag powder 811 having a particle size smaller than that of the ι 筛 sieve can be used for soil modification, as an acid test neutralization material φ or added to the cement. Used as a building material. As for the weld bead with a particle size smaller than the No. 4 sieve and larger than the No. 1GG sieve The fishing powder 811 can be used as a material for moisture adsorption. Referring to FIG. 6 and FIG. 2', a third preferred embodiment of the method for processing the bead slag of the present invention is substantially similar to the first embodiment. In a preferred embodiment, the method of treating the bead slag reuse of the present invention further comprises a grading step 71 and a regrinding step 72. The grading step η 8 201210710 is performed prior to the adding step 6. It is reasonable to be able to replace, and should not be in the preferred order of the present invention. The content disclosed in the preferred embodiment is limited to not repeating the screening step 5 and the different apertures in the classification step 71. The sieve has a particle size of "诹5 and is classified in the regrind (4) 72 1 = ^ material 811. / Grinding. The sieved crushed material (1) is sieved,

To confirm that the particle size is in line with expectations. In particular, in this comparative example, the particle size is greater than 4.75 mm (cannot be ground again by the 4 powder 811. Our flat side: as described above, the processing method of the bead of the present invention is reused. And the pulverization step 4 to treat the slag material plate 8 which is originally used as waste into the slag (4) 811, thereby facilitating the use of the weld bead material for water and gas adsorption, soil modification, The site can be improved, hardened, added to the sludge to absorb its water content, neutralize the pH value of the material, added to the expanded cement, and added to the building materials for subsequent recycling operations, thus enhancing its economic value and being more environmentally friendly. Therefore, it is possible to achieve the object of the present invention. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the scope of the patent application and the description of the invention according to the present invention.
