Description
본 발명은 저장용탱크의 저장량 측정장치에 관한 것으로, 상세하게는 저장용탱크나 싸이로에 저장된 물질(원료)의 저장량을 측정하기 위한 것으로, 탱크하측에 로드셀을 장착하여 탱크내의 원료량을 무게단위나 탱크체적 백분율로 측정할 수 있는 저장용탱크의 저장량 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring the storage amount of a storage tank. Specifically, the present invention relates to measuring a storage amount of a substance (raw material) stored in a storage tank or a cyclo, and loads a raw material in a tank by mounting a load cell under the tank. The present invention relates to a storage tank measuring device that can be measured in units or percentage of tank volume.
일반적으로 곡물이나 원료물질은 운송과정중이나 가공을 위한 목적으로 일정기간 저장이 필요하게 된다. 특히, 체적이 큰 물질인 경우에는 운송시 선박이 이용되며 선박으로부터 하역된 원료물질은 하역방법이나 다음 목적지로의 이동을 위하여 일정기간 저장되게 되며 이러한 저장목적에 주로 이용되는 것이 저장용탱크나 싸이로 등이 사용되고 있다.In general, grains or raw materials need to be stored for some time during the transport process or for processing purposes. In particular, in the case of a large volume of material, a vessel is used for transportation, and raw materials unloaded from the vessel are stored for a certain period of time in order to unload or move to the next destination, and a storage tank or cy Furnace etc. are used.
원료물질을 저장하는 싸이로나 저장탱크에는 저장부에 저장된 원료물질의 저장량 확인이 요구되며, 이는 저장탱크의 용량에 맞는 저장량을 유지함과 배출량의 정도를 확인하기 위한 목적으로 사용된다.Cyclones or storage tanks for storing raw materials are required to check the storage amount of the raw materials stored in the storage unit, which is used for the purpose of maintaining the storage capacity corresponding to the capacity of the storage tank and checking the extent of the discharge.
따라서 저장탱크나 싸이로에는 내용물의 부피 혹은 중량을 측정할 수 있는 측정장치가 부설되어 사용되고 있다.Therefore, the storage tank or the cyclo is used to install a measuring device that can measure the volume or weight of the contents.
일반적으로 사용되고 있는 측정장치는, 도 1에 도시된 바와 같이, 초음파 방식으로 탱크상측에서 초음파 발생기(110)를 사용하여 탱크내 저장물질에 반사되는 것을 측정하여 저장탱크 내의 내용물을 측정하는 장치이다. 그러나 상술한 방법은 내용물이 분체인 경우 탱크내에 주입된 분체는 주입구 수직하측으로 봉분형상이 형성되어 초음파가 접촉되는 부위에 따라 저장량 측정이 상이하게 나타나는 문제가 있으며, 저장원료가 미세한 분체인 경우에는 탱크내의 공기중에 부유되게 되어 초음파가 공기중에 부유되는 분체에 접촉되어 반사되는 경우 저장량이 실제보다 많게 측정되는 문제가 있어 정확한 저장량을 측정하기에는 어려움이 있었다.In general, the measuring apparatus, which is used, is an apparatus for measuring the contents of the storage tank by measuring the reflection on the storage material in the tank by using the ultrasonic generator 110 on the tank side in an ultrasonic manner. However, in the above-described method, when the contents are powder, the powder injected into the tank has a rod shape vertically below the inlet opening, so that the measurement of the storage amount differs depending on the area where the ultrasonic wave contacts, and the storage raw material is fine powder. When the ultrasonic wave is suspended in the air in the tank and reflected by contact with the powder suspended in the air, there is a problem that the storage amount is measured more than the actual, it was difficult to measure the accurate storage amount.
종래의 또 다른 방법으로는, 도 2에 도시된 바와 같이, 저장탱크, 싸이로를 지지하는 지지부 상에 상에 로드셀(130)을 설치하여 저장탱크는 물론 저장물의 무게를 측정한후 저장탱크의 무게를 제외시켜 저장물의 순수량을 측정하는 방법이 사용되고 있으나, 이러한 방법은 외부의 영향에 의해 측정량에 오차가 발생되는 문제가 있었다. 상기 내용을 상세하게 설명하면 탱크 외피면에 눈이나 기타 오물이 쌓이는 경우 쌓인 물질의 중량만큼 저장량의 오차가 발생되며, 또한 풍력(자연적인 바람)에 의해 탱크 중량이 가벼워져 오차가 발생되는 문제가 있었다.In another conventional method, as shown in Figure 2, by installing the load cell 130 on the storage tank, the support for supporting the cyclo and by measuring the weight of the storage tank as well as the storage tank of the storage tank Although the method of measuring the pure amount of the stored product by using the weight is used, this method has a problem that an error occurs in the measured amount due to external influences. When the above description is made in detail, when snow or other dirt accumulates on the outer surface of the tank, an error of the storage amount occurs as much as the weight of the accumulated material, and a problem that the error occurs due to the light weight of the tank due to wind power (natural wind). there was.
따라서, 본 발명이 이루고자 하는 기술적 과제는, 상술한 문제점을 해소하고 저장탱크 외측의 환경 변화에도 측정오차가 발생되지 않으며, 저장물질의 형상이나 종류의 변경에도 오차가 발생되지 않으며, 정확하게 저장물질의 량을 측정할 수 있는 저장용탱크의 저장량 측정장치를 제공함에 있다.Accordingly, the technical problem to be solved by the present invention is to solve the above-described problems, measurement errors do not occur even when the environment changes outside the storage tank, and error does not occur even when the shape or type of the storage material is changed. An object of the present invention is to provide a storage volume measuring device for a storage tank capable of measuring a quantity.

이하, 일실시예에 의한 도면으로 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the embodiment.
본 발명은 저장용탱크 하면을 형성하며 경사도를 갖는 경사부(13)의 중앙에 탱크수직 방향으로 관통홀(12)을 형성하고,The present invention forms a bottom surface of the storage tank and forms a through hole 12 in the tank vertical direction in the center of the inclined portion 13 having an inclination,

상기 케이스 연통홀(21) 단부에 결합되어 연통홀(21)과 탱크저장부(11)간에 수분과 분진의 이동을 방지하는 방진방수패드(50)와,A dustproof and waterproof pad 50 coupled to an end of the case communication hole 21 to prevent movement of moisture and dust between the communication hole 21 and the tank storage part 11;
상면이 상기 패드에 접촉되며 방진방수패드를 통해 전해지는 로드를 케에스(20) 하측에 구비된 로드셀(30)에 전달하는 로드버튼(40)으로 구성된다.The upper surface is in contact with the pad and consists of a load button 40 for transmitting the load transmitted through the dustproof waterproof pad to the load cell 30 provided on the lower side of the case (20).
이하, 본 발명의 작용에 관하여 서술하면 다음과 같다.Hereinafter, the operation of the present invention will be described.
본 발명이 구비된 저장탱크, 싸이로에 저장물을 주입하면 저장물은 하측으로 낙하되어 하면을 이루는 경사면에 접촉되게 된다.When the storage is injected into the storage tank and the cyclone provided with the present invention, the storage falls to the lower side to be in contact with the inclined surface forming the lower surface.
경사부(13)에 접촉되는 저장물은 하중에 의해 저장부(11)와 케이스(20)에 구비된 방수방진패드(50)에 하중을 전달하게 되며 하중을 전달받은 패드(50)는 패드하측에 접촉상태를 유지하는 로드버튼(40)에 재차하중을 전달하게 된다.The storage in contact with the inclined portion 13 transmits the load to the waterproof dustproof pad 50 provided in the storage portion 11 and the case 20 by the load, and the pad 50 received the load has a lower side of the pad. The load is transmitted again to the load button 40 maintaining the contact state.
하중을 전달받은 로드버튼은 하중을 하측의 로드셀(30)에 전달하게 되어 로드셀의 변화를 무게로 표시하거나, 탱크내 체적 백분율로 표시하거나, 탱크높이 길이단위로 표시하여 저장된 양을 알 수 있게 되는 것이다.The load button receiving the load transmits the load to the lower load cell 30 so that the change in the load cell can be displayed by weight, expressed as a percentage of the volume in the tank, or expressed in units of length of the tank height so that the stored amount can be known. will be.
상술한 저장량을 측정하는 원리는 로드버튼 단면적이 받고 있는 하중을 이용하여 무게를 측정하고 여기에 탱크의 단면적 배율을 곱하여 높이, 무게 체적을 표시하는 것이다.The principle of measuring the storage amount described above is to measure the weight using the load under the load button cross-sectional area, and multiply the cross-sectional magnification of the tank to display the height and weight volume.
또한 측정장치를 장착하는 관통홀(12)의 위치는 자유롭게 선택할 수 있으나 저장물이 분체인 경우 저장물이 주입구로부터 주입시 주입구 수직하측으로 봉분형상이 형성되는 것을 감안하고 주입구가 일반적으로 중앙에 위치되는 것을 감안할때, 탱크 하면에 형성된 경사부(13)의 중심점(O)과 탱크 측면의 중간에 형성시키는 것이 바람직하다. 즉, 관통홀(12)은 탱크하면 경사부(13)의 중심점(O)으로부터 탱크지름(D)의 1/4 지점(D/4) 상, 달리 말하면, 하면 경사부(13)의 1/2 지점(D/2) 상에 형성시킴으로써 상술한 봉분형상의 분체차이 높이에 따른 오차를 최소로 할 수 있다.In addition, the position of the through-hole 12 for mounting the measuring device can be freely selected. However, in the case where the storage material is powder, the injection hole is generally located at the center in consideration of the fact that a rod shape is formed vertically downward when the storage material is injected from the injection hole. In view of the above, it is preferable to form the center between the center point O of the inclined portion 13 formed on the lower surface of the tank and the side surface of the tank. That is, the through-hole 12 is located on the 1/4 point (D / 4) of the tank diameter (D) from the center point (O) of the lower surface inclined portion 13, in other words, 1/1 of the lower surface inclined portion (13) By forming on two points (D / 2), the error according to the powder difference height of the above-mentioned rod-shaped powder can be minimized.
본 발명의 효과로는 저장물질의 형상이나 종류에 따라 구애받지 않고 저장물질의 분체인 경우에도 측정오차를 최소로하여 정확하게 저장량을 측정할 수 있으며 측정장치가 저장부 내부의 저장물질에 연계되어 탱크 외측의 환경 변화에도 영향받지 않고 항상 정확하게 저장량을 측정할 수 있는 효과가 있다.According to the effects of the present invention, regardless of the shape or type of the storage material, even in the case of powder of the storage material, it is possible to accurately measure the storage amount by minimizing the measurement error, and the measuring device is connected to the storage material inside the storage tank. There is an effect that it is possible to accurately measure the amount of storage at all times without being affected by changes in the environment outside.
