도1은 이러한 제강 슬래그를 크기별로 분리하는 공정을 보이는 개략도로써, 원료공급호퍼(1)에 제강 슬래그를 투입하면 제1벨트컨베이어(2)를 통해 스크린(3)으로 공급되며, 이에 투입되는 원료는 스크린(3)을 통과하면서 가는 것은 가이드(4)를 통해 하측의 제2벨트컨베이어(5)로 떨어져 제4벨트컨베이어(7)에 의해 1차로 모아지게 되고, 비교적 굵은 것은 제3벨트컨베이어(6)에 의해 별도로 모아지게 된다.Figure 1 is a schematic diagram showing a process for separating the steelmaking slag by size, when the steelmaking slag is put into the raw material supply hopper 1 is supplied to the screen 3 through the first belt conveyor (2), the raw material introduced thereto Is passed through the screen (3) to the lower second belt conveyor (5) through the guide 4 is collected by the fourth belt conveyor (7), the relatively thick is the third belt conveyor ( 6) are collected separately.
이와 같이 선별된 원료는 선별된 크기별로 2차 공정에 투입하게 되는데, 그 제조방법을 특허 등록 제98 - 165692호를 참조하면 다음과 같다.The selected raw materials are put into the secondary process according to the selected size. Referring to Patent Registration No. 98-165692, the manufacturing method is as follows.
물에 고형물이 60-70% 함유되도록 고형물에 물을 투입하고 이와 같은 상태의 슬래그를 회전 드럼에 투입하여 세척하므로 고형물을 세척하고 이에 함유된 불순물이 어느 정도 제거하게 되며, 세척된 원료를 건조시킨 후 적정량씩 포장한다.Water is added to the solids so that 60-70% of the solids are contained in the water, and the slag in such a state is put into the rotating drum to wash the solids, and the impurities contained therein are removed to some extent, and the washed raw materials are dried. After packing the appropriate amount.
그런데 이러한 종래 제강 슬래그를 이용한 미끄럼방지 시설용 골재 제조방법은 몇가지 문제가 발생하였는바, 골재가 드럼에서 비벼진 후, 스크린에서 분사노즐로 세척된 다음, 건조, 포장되므로 세척상태가 좋지 못하였으며, 이에 따라 접착제나 시멘트 등을 골재에 혼합할시 접착력이 저하되고, 시공시 불량발생률이 증가되었다.By the way, the conventional method for producing aggregates for non-slip facility aggregates using steelmaking slag occurred, after the aggregates were rubbed in the drum, washed with the spray nozzles on the screen, and then dried and packaged, so that the cleaning conditions were not good. Accordingly, when the adhesive or cement is mixed in the aggregate, the adhesive strength is lowered, and the failure rate during construction is increased.
또한 골재가 세척될시 물에 골재가 60-70% 정도 혼합된 상태에서 세척되므로 물에 비해 골재의 비율이 높아 제대로 세척되지 못하였고, 따라서 골재에 함유된 불순물이 제대로 제거되지 못하였다.In addition, when the aggregate is washed, the aggregate is washed in a state of about 60-70% mixed with water, so the ratio of aggregate is higher than water, and thus, the aggregate is not properly washed. Therefore, impurities contained in the aggregate are not properly removed.

그리고 공급피더(12) 일측에는 세척기(16)가 설치되어 있는바, 이는 1차 세척된 골재를 이송시키면서 세척하도록 저수조(17) 내에 원통형 드럼(18)이 구비되고, 드럼(18) 양측에 각각 제2분사노즐(19) 및 제3분사노즐(20)이 설치되어 있다.And one side of the feed feeder 12 is provided with a washing machine 16, which is provided with a cylindrical drum 18 in the reservoir 17 for cleaning while transporting the first-cleaned aggregate, respectively, on both sides of the drum 18 The second spray nozzle 19 and the third spray nozzle 20 are provided.
세척기(16)의 드럼(18) 일측 하부에는 스크린(21)이 설치되어 있고, 스크린(21) 일측에는 제1바켓벨트컨베이어(23)가 설치되어 있으며, 그 일측에 드라이어(24)가 설치된다.A screen 21 is installed at one lower side of the drum 18 of the washing machine 16, and a first bucket belt conveyor 23 is installed at one side of the screen 21, and a dryer 24 is installed at one side thereof. .
한편 드라이어(24) 일측에는 제2바켓벨트컨베이어(25)가 설치되고, 그 일측으로 제품호퍼(26)가 설치되며, 이 제품호퍼(26)에는 제품분리스크린(29)이 설치되어 있어 제2바켓벨트컨베이어(25)로부터 공급된 골재를 분리한 후 적정크기 이하의 골재는 하측으로 떨어뜨리도록 되어 있다.Meanwhile, a second bucket belt conveyor 25 is installed at one side of the dryer 24, and a product hopper 26 is installed at one side thereof, and a product separation screen 29 is installed at the product hopper 26. After separating the aggregate supplied from the bucket belt conveyor 25, the aggregate below the appropriate size is to fall to the lower side.
그리고 제품호퍼(26) 일측에는 제품분리스크린(29)을 통과한 골재를 일정량씩 자동포장하도록 자동포장기(27)가 설치되며, 자동포장기(27) 일측에 이송컨베이어(28)가 설치되어 있다.And on one side of the product hopper 26 is an automatic packaging machine 27 is installed to automatically package the aggregate passing through the product separation screen 29 by a predetermined amount, the conveying conveyor 28 is installed on one side of the automatic packaging machine 27.
이러한 구성의 본 발명 제강 슬래그를 이용한 미끄럼방지 시설용 골재 제조장치의 작용은 다음과 같다.The function of the aggregate production apparatus for an anti-slip facility using the present invention steelmaking slag of such a configuration is as follows.
호퍼(11)에 투입된 골재를 공급피더(12)로 공급하면 스크류(14)에 의해 상측으로 이송되어 세척기(16)로 공급된다.When the aggregate injected into the hopper 11 is supplied to the feed feeder 12, the aggregate is transferred upward by the screw 14 and supplied to the washing machine 16.
여기서 골재가 스크류(14)에 의해 이송되는 동안 제1분사노즐(15)이 작동되어 이에 물을 분사하게 되어 골재에 함유된 불순물을 씻겨 내리게 된다.Here, while the aggregate is transported by the screw 14, the first spray nozzle 15 is operated to spray water thereon to wash away impurities contained in the aggregate.
이와 같이 하여 공급피더(12)를 통과하는 동안 1차 세척된 골재는 세척기(16)에 투입되어 2차 세척되는바, 세척기(16)의 저수조(17)에는 어느 정도의 물이 담겨지 있고 이 저수조(17)에 드럼(18)의 하부가 약간 잠기도록 설치되어 있으며, 드럼(18) 내부에는 나선형 스크류(미도시)가 구비되어 있어 드럼 내부에 투입된 골재를 이송시킬 수 있도록 되어 있으므로 드럼이 회전되면 골재()가 이송되면서 저수조(17) 내의 물에 의해 세척된다.In this way, the aggregate washed first while passing through the feed feeder 12 is put into the washer 16 and is washed secondly, the reservoir 17 of the washer 16 contains a certain amount of water and this reservoir The lower part of the drum 18 is installed in the 17 so as to be slightly submerged, and the drum 18 is provided with a spiral screw (not shown) so that the aggregate injected into the drum can be transported. Aggregate (A) is transported and washed by water in the reservoir (17).
이때 골재가 드럼(18) 내부를 통과하는 동안 제2분사노즐(19)과 제3분사노즐(20)로부터 물이 분사되어 골재를 재차 세척하게 된다.At this time, water is sprayed from the second spray nozzle 19 and the third spray nozzle 20 while the aggregate passes through the drum 18 to wash the aggregate again.
여기서 드럼 내부의 물과 골재의 혼합비율은 물 97-98%에 골재 2-3% 정도이다.Here, the mixing ratio of water and aggregate in the drum is about 97-98% of water and 2-3% of aggregate.
따라서 많은 양의 물에 약간의 골재를 넣어서 세척하게 되므로 골재가 깨끗히 세척되고 골재에 함유된 불순물이 공급피더(12) 및 드럼(18)을 통과하는 동안 확실하게 제거된다.Thus, a small amount of aggregate is put into a large amount of water so that the aggregate is washed cleanly and impurities contained in the aggregate are reliably removed while passing through the feed feeder 12 and the drum 18.
이와 같이 세척된 골재는 드럼(18) 일측 하부에 구비된 스크린(21)으로 공급되는데, 세척기(16)를 통과한 골재가 스크린(21)에 공급될시 제4분사노즐(22)이 작동되어 공급되는 골재에 물을 분사하므로 이를 다시 세척하게 된다.The aggregate washed in this way is supplied to the screen 21 provided at the lower side of the drum 18, the fourth spray nozzle 22 is operated when the aggregate passed through the washing machine 16 is supplied to the screen 21 Water is sprayed on the aggregate to be cleaned again.
3차 세척되어 스크린(21)에 공급된 골재는 제1바켓벨트컨베이어(23)에 의해 드라이어(24)에 투입되고, 드라이어(24)를 통과하는 동안 건조되며, 제2바켓벨트컨베이어(25)에 의해 제품호퍼(26)로 공급되며, 제품호퍼(26)에 투입된 골재는 제품분리스크린(29)을 거쳐 자동포장기(27)로 공급된다.Aggregate washed and supplied to the screen 21 is charged into the dryer 24 by the first bucket belt conveyor 23, dried while passing through the dryer 24, and the second basket belt conveyor 25. It is supplied to the product hopper 26, the aggregate injected into the product hopper 26 is supplied to the automatic packaging machine 27 via the product separation screen (29).
자동포장기(27)를 통과한 골재는 단위포장되어서 이송컨베이어(28)로 이송되어 적재된다.Aggregate that has passed through the automatic packing machine 27 is packed in units and transported to the conveying conveyor 28.
이러한 본 발명 제강 슬래그를 이용한 미끄럼방지 시설용 골재 제조장치는, 몇 가지 장점을 가지는바, 첫째, 골재가 세 차례에 걸쳐서 세척된다. 즉, 골재가 공급피더(12)를 통해 호퍼(11)에서 세척기(16)로 이송되는 동안 제1분사노즐(15)에 의해 세척되고, 세척기를 통과하는 동안 드럼(18), 제2분사노즐(19), 제3분사노즐(20)에 의해 2차 세척되며, 세척기(16)에서 스크린(21)으로 공급되는 동안 제4분사노즐(22)에 의해 3차 세척되므로 골재의 세척상태가 깨끗하고, 불순물이 확실하게 제거되며, 이에 따라 골재를 접착제나 시멘트에 혼합할시 결합력이 증대되어 시공된 상태가 견고해진다.The aggregate production apparatus for an anti-slip facility using the steelmaking slag of the present invention has several advantages, first, the aggregate is washed three times. That is, the aggregate is washed by the first spray nozzle 15 while the aggregate is transferred from the hopper 11 to the washer 16 through the feed feeder 12, and the drum 18, the second spray nozzle while passing through the washer. (19), the second washing by the third spray nozzle 20, the third washing by the fourth spray nozzle 22 while being supplied to the screen 21 from the washing machine 16, so that the washing state of the aggregate is clean In addition, the impurities are reliably removed, thereby increasing the bonding strength when the aggregate is mixed with the adhesive or the cement, thereby strengthening the constructed state.
둘째, 세척기(16) 내의 슬래그가 묽어서 골재가 확실하게 세척된다. 즉, 세척기(16) 내의 물과 골재의 혼합비율이 물 97-98%에 골재2-3%이므로 물에 비해 골재의 양이 매우 적어서 드럼(18)이 회전되는 동안 골재가 저수조(17) 내의 물을 통과하면서 충분히 세척되며, 이에 따라 상술한 동일한 효과가 있게 된다.Second, the slag in the washer 16 is thin so that the aggregate is reliably washed. That is, since the mixing ratio of water and aggregate in the washing machine 16 is 97-98% of water and 2-3% of aggregate, the amount of aggregate is very small compared to water so that the aggregate is in the reservoir 17 while the drum 18 is being rotated. It is sufficiently washed while passing through water, thereby having the same effect as described above.
이와 같은 본 고안 제강 슬래그를 이용한 미끄럼방지 시설용 골재 제조장치에 의해 제조된 골재는, 골재의 세척상태가 매우 양호하여 접착제, 시멘트 등에 잘 혼합되어 접착력이 향상되며, 이에 따라 시공 상태가 견고하게 된다.The aggregate produced by the aggregate production apparatus for an anti-slip facility using the present invention steelmaking slag is very good cleaning state of the aggregate is mixed well with adhesives, cement, etc., the adhesion is improved, and thus the construction state is firm.
이상에서와 같은 본 발명에 따른 제강 슬래그를 이용한 미끄럼방지 시설용 골재 제조장치에 의하면, 골재가 공급피더(12)를 지나는 동안 제1분사노즐(15)에 의해 1차 세척되고, 세척기(16)를 통과하는 동안 물에 일부가 잠긴 상태에서 회전되는 드럼(18) 및 제2분사노즐(19), 제3분사노즐(20)에 의해 2차 세척되며, 세척기(16)에서 스크린(21) 상으로 공급되는 동안 제4분사노즐(22)에 의해 3차 세척되고, 세척기(16)에 투입되는 슬래그의 비율이 물97-98%에 골재2-3% 이어서 골재 사이에 끼거나 붙은 불순물이 물에 확실하게 세척되는 등, 전체적으로 골재의 세척상태가 매우 양호하므로 세척된 상태의 골재가 접착제, 시멘트 등에 잘 혼합되어 접착력이 향상되며, 이에 따라 시공 상태가 양호하여 장기간 지나도 손상되지 않는 등의 효과가 있다.According to the aggregate production apparatus for an anti-skid facility using steelmaking slag according to the present invention as described above, the aggregate is first washed by the first spray nozzle 15 while passing the feed feeder 12, the washing machine 16 Secondary cleaning is performed by the drum 18, the second spray nozzle 19, and the third spray nozzle 20, which are rotated while partially submerged in water during the passage, from the washer 16 onto the screen 21. The third slag washed by the fourth spray nozzle 22 while being fed, and the ratio of slag introduced into the washer 16 is 97-98% of water and 2-3% of aggregate, and impurities trapped or stuck between aggregates As the overall cleaning condition of the aggregate is very good, it is well washed, and thus the aggregate in the cleaned state is mixed well with adhesives and cements, thereby improving adhesive strength. .
