본 고안은 철광석류 특히 소결광의 낙하강도를 측정하는 장치에 관한 것이다.The present invention relates to a device for measuring the falling strength of iron ore, in particular sintered ore.
일반적으로 용선 제조시 주원료인 소결광은 일정 기준 이상의 내충격성음 유지하여야 하므로 용광로 장입직전에 정기적으로 이를 측정하며 측정기준은 입자크기 10-70m/m의 소결광시료 20kg을 2M 높이에서 4회 낙하시킨 다음 아래 공식에 의거 낙하강도를 산출해 낸다.In general, sintered ore, which is the main raw material in the manufacture of molten iron, must maintain the impact resistance sound over a certain standard, so it is measured regularly just before the blast furnace is charged. Calculate the drop strength according to the formula.
S : 낙하강도S: dropping strength
A : 장입된 시료량A: amount of loaded sample
B : 4회 낙하시킨 시료 중 입자크기 10m/m 이상인 시료량B: Sample amount having a particle size of 10 m / m or more among the samples dropped four times
분 고안은 이러한 철광석 낙하강도의 측정장치를 개설한 것으로 종래에는 밑면이 열릴 수 있게 된 상자에 시료를 넣고 구동 와이어로프(wire Rope)를 이용 2M 높이로 올린 다음 시료상자의 밑면을 열어 낙하판에 시료를 낙하시킨 다음, 낙하된 시료를 모아 다시 같은 동작으로 시료를 4회 낙하시켜 측정하여 왔으나, 시트상자의 밑면 개폐가 순조롭지 못하여 고장이 심하고 시료의 낙하시 먼지의 발생으로 작업조건이 불량하며 많은 인력이 소요되었고 측정시간이 장기간 소요되었다.Invented is a device for measuring the iron ore drop strength, conventionally put the sample in a box that can open the bottom, raise the sample to 2M height using a drive wire rope, then open the bottom of the sample box to the drop plate After dropping the sample, the dropped sample was collected and the sample was dropped four times with the same operation.However, the bottom of the sheet box was not opened and closed smoothly. It took a lot of manpower and a long measurement time.
본 고안은 이러한 문제점을 해결하기 위하여 장방향의 철판으로 된 본체 양단에 개폐가능한 시료통을 설치하고 회전장치로 본체를 회전시켜 시료가 낙하되도록 한 것으로 본 고안의 구성 및 작동을 첨부된 도면에 의해 설명하면 다음과 같다.The present invention is to solve this problem by installing a sample container that can be opened and closed on both ends of the main body made of iron plate in the longitudinal direction and by rotating the main body with a rotating device to drop the sample by the accompanying drawings the configuration and operation of the present invention The explanation is as follows.
장방형의 철판으로 된 본체(1)의 양단에 에어실린더(c)(d)와 필(14)(14′)(14″)으로 연결된 로든(15)(15′)의 작동으로 개폐가 가능한 조절판(4)(4′)이 부착된 시료통(3)(3′)을 설치하고, 하부의 시료통(3′)에는 에어실린더(a)에 의해 개폐되는 시료장입문(2)과 에어실린더(b)에 의해 개폐되는 배출문(2′)을 설치한다. 에어 주입구(12)(12′)에 에어를 주입하여 좌우 이동이 되는 래크(Lack)(10)와, 래크(10)의 이동에 따라 회전이 되며 회전축(5)과 연결된 피니언(Pinion)(11)으로 구성된 회전장치(7)를 회전지지대(6) 위에 설치하고 리미트스위치(Limit Switch)(9)의 작동으로 회전을 제동시키는 전자제동장치(Magnetic Braker)(8)를 설치한 것으로 미설명부호 13,13′는조절판(4)(4′)의 개폐측이다.Control panel that can be opened and closed by operation of rodin 15 (15 ') connected by air cylinders (c) (d) and fills (14) (14') (14 ") at both ends of main body (1) of rectangular iron plate (4) A sample container (3) (3 ') with (4') attached thereto, and a sample loading door (2) and an air cylinder opened and closed by an air cylinder (a) in the lower sample container (3 '). Install the discharge door 2 'which is opened and closed by (b). The rack 10 is moved left and right by injecting air into the air inlets 12 and 12 ', and the pinion 11 rotates according to the movement of the rack 10 and is connected to the rotation shaft 5. Is installed on the rotary support (6) and an electromagnetic brake (8) for braking rotation by the operation of the limit switch (9). 13 and 13 'are the opening and closing sides of the control plate 4 and 4'.
에어실린더(a)(b)(c)(d) 및 회전장치(7)의 작동은 조작패널(Panel)의 조작으로 솔레노이드밸브(도시하지 아니함)에 의해 공급되는 에어에 의해 작동이 된다. 이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.The operation of the air cylinders (a) (b) (c) (d) and the rotary device 7 is operated by air supplied by a solenoid valve (not shown) by operation of an operation panel. Referring to the effect of the present invention configured as described above are as follows.
조작 패널의 조작으로 회전장치(7)를 작동시켜 본체(1)를 약 75° 정도 회전시키고 전자 제동장치(8)를 작동 정지시킨 다음 에어실린더(a)를 작동하여 장입문(2)를 열고 시료를 하부 시료통(3′)에 장입한 후 회전장치(7)를 작동시켜 본체(1)가 직립되면 리미트스위치(9)의 작동으로 전자제동장치(8)가 작동하여 본체(1)를 정지시킨다. 이때 조절판(4)은 열린 상태이며 조절판(4′)과 본체(1) 밑면과 거리는 2M이다. 에어실린더(d)를 작동시키면 제3도와 같이 필(14)(14′)(14″)으로 연결된 로드(15)(15′)가 조절판 개폐축(13)(13′)을 회전시켜 조절판(4′)이 개폐축(13)(13′)을 중심으로 양쪽으로 열리면서 본체(1) 밑면으로 시료가 낙하된다(1회 낙하) 시료가 낙하된 후 에어실린더(c)에 의해 조절판이 닫히면서 에어 주입구(12′)에 에어를 주입, 회전장치를 역회전시키면 시료가 들어있는 시료통(3)이 상부에 위치하게 되며 본체가 직립된 상태에서 리미트 스위치(9)에 의해 전자 제동장치(8)가 작동하여 본체를 정지시키며 1회 때와 같은 조작으로 시료를 낙하시킨다. 이렇게 4회 낙하시킨 후 시료통(3′)에 부착된 에어실린더(b)를 작동시켜 배출문(2′)을 열어 시료를 배출시킨다. 이상과 같은 작용으로 측정시간의 단축과 인력절감은 물론 시료의 낙하가 본체(1) 안에서 이루어지므로 먼지 발생이 방지되어 작업환경 개선에 효과가 큰 고안이다.Operate the rotary device (7) by operating the operation panel to rotate the main body (1) by about 75 °, stop the electromagnetic brake (8), then operate the air cylinder (a) to open the charging door (2) After loading the sample into the lower sample container (3 '), the rotary device (7) is operated and the main body (1) is upright, and the electronic brake device (8) is operated by the limit switch (9) to operate the main body (1). Stop it. At this time, the throttle 4 is open and the distance between the throttle 4 'and the bottom of the main body 1 is 2M. When the air cylinder d is operated, the rods 15 and 15 'connected to the pillars 14, 14' and 14 " as shown in FIG. 3 rotate the adjustment plate opening and closing shafts 13 and 13 'to adjust the adjustment plate ( 4 ') is opened on both sides of the opening and closing shafts 13 and 13', and the sample is dropped to the bottom of the main body 1 (once drop). After the sample is dropped, the control plate is closed by the air cylinder c. When air is injected into the air inlet 12 'and the rotating device is rotated reversely, the sample container 3 containing the sample is positioned at the upper portion, and the electronic brake device 8 is provided by the limit switch 9 in the state where the main body is upright. ) Is operated to stop the main body and the sample is dropped by the same operation as in the first time. After dropping four times in this manner, the air cylinder (b) attached to the sample container 3 'is operated to open the discharge door 2' to discharge the sample. As described above, the shortening of the measurement time and the manpower reduction, as well as the dropping of the sample is made in the main body 1, prevents the occurrence of dust.
