Description

먼지필터를 구비한 노면 청소차{Road sweeper with wet filter} Road sweeper with wet filter

본 발명은 먼지필터를 구비한 노면 청소차에 관한 것으로서, 더욱 상세하게는 노면청소차의 적재함에 적재되는 쓰레기와는 달리 먼지를 비산되지 않도록 하되, 배기덕트의 철재망을 제거하고 먼지필터를 설치하여 막히지 않고 비산먼지를 처리해주는 먼지필터를 구비한 노면 청소차에 관한 것이다.The present invention relates to a road sweeper equipped with a dust filter, and more specifically, to prevent dust from being scattered, unlike the garbage loaded in the loading box of the road sweeper, but does not get clogged by removing the steel net of the exhaust duct and installing a dust filter. The present invention relates to a road sweeper equipped with a dust filter that treats scattered dust.

최근에 국민 의식 수준의 향상으로 주변 환경 미화에 대한 관심이 날로 증대되고 있으며, 특히 도시 미관과 관련하여 폐기물의 처리가 중요시되고 있다. Recently, the interest in beautification of the surrounding environment has been increasing day by day with the increase in the level of public awareness, and waste treatment is particularly important in relation to urban aesthetics.

이러한 환경에서, 도로 주변에 흩어져 있는 낙엽이나 쓰레기, 모래 등과 같은 노상 쓰레기들은 도시 미관을 해칠 뿐만 아니라 하수관거로 흘러들어가거나 수질 오염을 유발하게 되므로 수시로 이를 제거할 필요가 있다. In this environment, road debris scattered around the road, such as fallen leaves, garbage, sand, etc., not only harms the aesthetics of the city, but also flows into sewage pipes or causes water pollution, so it is necessary to remove them from time to time.

따라서, 정부에서는 청소장비를 탑재한 청소차량을 이용하여 노상 쓰레기를 처리하고 있는데, 대체로 종래의 노면청소차는 블로워가 작동하면서 흡입력을 발생함으로써 롤러브러시가 쓸어내는 노면의 쓰레기 및 오물등을 적재함의 내부로 연결된 흡입관을 통해 적재함으로 수거하며, 상기 블로워의 외측으로는 배출구가 구비됨으로써 적재함을 거치면서 쓰레기와 오물을 낙하하고 난 흡입 공기는 블로워의 강력한 흡입력으로 인해 배출구를 통하여 대기중으로 방출한다. Therefore, the government processes road trash using a cleaning vehicle equipped with cleaning equipment. In general, the conventional road cleaning vehicle generates suction power while the blower operates, thereby loading garbage and dirt on the road surface that the roller brush sweeps away. Collected through the suction pipe connected to the inlet, and the outside of the blower is provided with an outlet so that the intake air after dropping the garbage and dirt through the loading bin is discharged into the atmosphere through the outlet due to the strong suction power of the blower.

이러한 노면청소차에 관련한 선행기술로는 대한민국특허등록번호 제1827474호인 흡입력이 향상된 에어젯팅 시스템 및 미세먼지 방출 억제 필터제어 시스템이 적용된 도로 분진흡입차가 개시되고 있다. As a prior art related to such a road cleaning vehicle, a road dust inhalation vehicle in which an air jetting system with improved suction power and a filter control system for controlling fine dust emission are applied has been disclosed.

상기 선행기술은 대기중으로 배출되는 에어를 인출하여 리싸이클링 하는 과정에서 흡입마우스 내에 위치한 도로의 공극에 고압의 에어젯을 분사함으로써 공극에 끼인 분진을 부상시켜 완벽하게 흡입 제거함으로써 흡입효율을 대폭 향상하는 효과를 제공한다. In the prior art, in the process of drawing out and recycling air discharged to the atmosphere, a high-pressure air jet is injected into the air gap of the road located in the suction mouse to induce and completely remove the dust trapped in the air gap, thereby significantly improving the suction efficiency. Provides

그러나, 노면청소차의 적재함에 적재되는 쓰레기와는 달리 먼지를 비산되지 않도록 하되, 막히지 않고 비산먼지를 처리해주는 습식필터식의 노면 청소차를 제공하지 못하여 비산먼지를 처리하는데 문제가 발생하였다.However, unlike the garbage loaded in the loading box of the road surface cleaning vehicle, the dust is not scattered, but a wet filter type road surface cleaning vehicle that does not get clogged and handles the scattering dust is not provided, thus causing a problem in handling the scattering dust.

또한, 블로워에 의한 진공흡입력으로는 노면 공극에 끼인 이물질과 비중 있는 잔량의 이물질 등을 전부 흡입하기 어려워 작업자가 흡입상태를 실시간 확인해가면서 운전을 병행해야 하기 때문에 급격한 피로도를 유발하는 문제점이 야기된다.In addition, the vacuum suction input by the blower is difficult to inhale all the foreign matters stuck in the road surface pores and the heavy residual amount of foreign matters, so the operator must check the inhalation state in real time and run in parallel, causing a problem that causes rapid fatigue.

그리고, 노면청소시 노면의 각종 쓰레기를 미세먼지 방출 없이 청소하기 위해 구간별로 물을 분사함에 있어 물과 혼합된 각종 이물질을 흡입하여 적재함에 수거하는 과정에서 흡입마우스 및 흡입라인 내부 표면에 달라붙어 흡입마우스의 단면적을 축소시켜 흡입성능이 저하되는 현상이 발생한다.In addition, when cleaning the road surface, in order to clean various wastes on the road surface without releasing fine dust, in the process of inhaling various foreign substances mixed with water and collecting them in the loading box, the suction mouse and the suction line adhere to the inside surface and suck it. A phenomenon in which suction performance decreases by reducing the cross-sectional area of the mouse occurs.

따라서, 상기한 문제점을 해결할 수 있는 새로운 방식의 노면 청소차를 개발할 필요가 대두되게 되었다.Accordingly, there is a need to develop a new type of road sweeper that can solve the above problems.

도 1은 본 발명의 일실시예에 따른 먼지필터를 구비한 노면 청소차의 개략도이다.1 is a schematic diagram of a road cleaning vehicle having a dust filter according to an embodiment of the present invention.

도 1에 도시한 바와 같이, 상기 노면 청소차(10)에는, 엔진(30)룸이 구성되어 있으며, 엔진룸과 블로워(60)가 구성되어 있어 엔진을 구동시키게 되면 블로워가 동작하여 진공을 발생시키게 된다.As shown in FIG. 1, the road cleaning car 10 includes an engine 30 room, and an engine room and a blower 60 are configured so that when the engine is driven, the blower operates to generate vacuum. do.

또한, 하측에 구성된 청소부(90)가 회전하게 되면 노면에 존재하는 이물질들을 청소하게 되고, 청소부의 지근 거리에 구성된 흡입마우스(40)를 통해 이물질들을 흡입하게 되는 것이다.In addition, when the cleaning unit 90 configured on the lower side is rotated, foreign substances existing on the road surface are cleaned, and foreign substances are sucked through the suction mouse 40 configured at a close distance of the cleaning unit.

상기 흡입마우스를 통해 흡입된 이물질들은 적재함(95)으로 이동하고, 부피가 있는 이물질들은 적재함에 적재가 되고, 비산먼지와 같은 작은 이물질들은 상부 배기덕트(91)를 거쳐 전면에 위치한 필터박스(2)를 거쳐 블로워의 일측에 구성된 배기덕트(2)를 거쳐 밖으로 방출하는 구조를 가지게 된다.Foreign matter sucked through the suction mouse moves to the loading box 95, bulky foreign matter is loaded into the loading box, and small foreign matter such as scattering dust passes through the upper exhaust duct 91 to locate the filter box (2). ) Through the exhaust duct (2) configured on one side of the blower to have a structure to discharge to the outside.

이때, 본 발명에서는 노면청소차의 배기덕트(20)에 먼지필터인 공조용배그필터(100)를 설치하여 비산 먼지가 대기로 방출되지 않도록 하는 것을 특징으로 한다.At this time, the present invention is characterized in that by installing a dust filter air conditioning bag filter 100 in the exhaust duct 20 of the road surface cleaning vehicle so that scattered dust is not released into the atmosphere.

결국, 적재함에 적재되는 쓰레기와는 달리 먼지를 비산되지 않도록 하되, 배기덕트의 철재망을 제거하고 먼지필터를 설치하여 막히지 않고 비산먼지를 처리해주는 먼지필터를 구비한 노면 청소차를 제공함으로써, 비산먼지의 대기 방출을 방지하는 효과를 제공하게 된다.In the end, unlike the garbage loaded in the loading box, the dust is not scattered, but by removing the steel net of the exhaust duct and installing a dust filter, by providing a road cleaning vehicle equipped with a dust filter that handles the scattering dust without clogging, it provides scattering dust. It provides the effect of preventing the release of air into the air.

또한, 본 발명에서 설명하고 있는 먼지필터는 미세먼지, 비산먼지 등 각종 흡입되는 먼지 등을 처리(필터링)할 수 있는 필터를 의미하며, 예를 들어, 건식필터 방식이 될 수 있으며, 필요에 따라 습식필터 방식이 될 수도 있을 것이다.In addition, the dust filter described in the present invention refers to a filter capable of processing (filtering) various kinds of inhaled dust such as fine dust and scattered dust, and may be, for example, a dry filter method, as required It may be a wet filter method.

즉, 먼지를 필터링할 수 있는 필터라면 어떠한 종류의 필터라도 상관없을 것이다.That is, any type of filter may be used as long as it is a filter capable of filtering dust.

한편, 부가적인 양상에 따라, 상기 노면청소차(10)는, On the other hand, according to an additional aspect, the road cleaning car 10,

엔진(30)을 이용하여 진공을 발생시켜 흡입력을 생성하며, 블로워(60)를 통하여 이미 발생된 진공을 통한 흡입력의 강도를 증가시키는 것을 특징으로 한다.It is characterized by generating a suction force by generating a vacuum using the engine 30, and increasing the strength of the suction force through the vacuum already generated through the blower 60.

즉, 엔진을 구성하고 있으며, 엔진을 통해 진공을 발생시켜 흡입력을 생성하게 된다.That is, the engine is configured, and vacuum is generated through the engine to generate suction power.

이때, 블로워(60)를 통해 이미 발생된 진공을 통한 흡입력의 강도를 종래보다 더욱 증가시키게 되는 것이다.At this time, the strength of the suction force through the vacuum that has already been generated through the blower 60 is further increased than in the prior art.

또한, 도 2에 도시한 바와 같이, 흡입마우스(40)의 후단에 압력센서(50)를 설치하여 흡입력을 피드백하며, 흡입력의 기준치에 미치지 못할 시, 제어부(70)를 통하여 상기 엔진(30) 혹은 블로워(60)의 파워를 증가시키는 것을 특징으로 한다.In addition, as shown in FIG. 2, the pressure sensor 50 is installed at the rear end of the suction mouse 40 to feed back the suction force, and when it does not reach the reference value of the suction force, the engine 30 is controlled through the control unit 70. Or it is characterized by increasing the power of the blower (60).

예를 들어, 기준치를 2기압으로 설정하게 되면, 압력센서에서 2기압 이하의 압력을 감지하게 되면 제어부에서는 엔진의 현재 rpm을 상승시키기 위한 rpm 상승 신호를 생성하여 엔진에 제공하게 된다.For example, when the reference value is set to 2 atm, when the pressure sensor detects a pressure of 2 atm or less, the control unit generates an rpm rise signal for raising the current rpm of the engine and provides it to the engine.

이후, 블로워의 rpm도 동시에 상승시키는 rpm 상승 신호를 생성하여 블로워에 제공하게 된다.Thereafter, an rpm rising signal that simultaneously raises the rpm of the blower is generated and provided to the blower.

이후, 압력센서에서 흡입력의 기준치 값과 주기적으로 비교하여 기준치 값을 초과할 경우에 최초 설정된 rpm 값으로 복귀시키게 된다.Thereafter, the pressure sensor periodically compares with the reference value of the suction force to return to the first set rpm value when the reference value is exceeded.

상기와 같은 구성 및 동작에 의하면, 엔진을 이용하여 진공을 발생시켜 흡입력을 생성하며, 블로워를 통하여 이미 발생된 진공을 통한 흡입력의 강도을 증가시키는 것을 특징으로 하며, 흡입마우스의 후단에 압력센서를 설치하여 흡입력을 피드백하며, 흡입력의 기준치에 미치지 못할 시, 제어부를 통하여 상기 엔진 혹은 블로워의 파워를 증가 흡입력만으로 부양되지 않는 분진, 미세먼지 등까지도 부양시켜 최적의 흡입력을 얻을 수 있는 효과를 제공하게 된다.According to the configuration and operation as described above, the vacuum is generated by using the engine to generate suction power, and it is characterized by increasing the strength of suction power through the vacuum already generated through the blower, and a pressure sensor is installed at the rear end of the suction mouse. In this way, the suction power is fed back, and when it does not reach the reference value of the suction power, the power of the engine or blower is increased through the control unit to support even dust and fine dust that are not supported by the increased suction power, thereby providing the effect of obtaining the optimal suction power. .

한편, 다른 부가적인 양상에 따라, 흡입력의 기준치에 미치지 못할 경우에, 역분사부(80)를 통하여 엔진 및 블로워의 풍속을 인입하여 흡입마우스에 역분사하여 막힘을 해결하는 것을 특징으로 한다.On the other hand, according to another additional aspect, when it does not reach the reference value of the suction force, it is characterized in that it solves the clogging by injecting the wind speed of the engine and blower through the reverse injection unit 80 to the suction mouse.

예를 들어, 기준치를 2기압으로 설정하였다면, 압력센서에서 2기압 이하의 압력을 감지하게 되면 제어부에서는 엔진의 현재 rpm을 상승시키기 위한 rpm 상승 신호를 생성하여 엔진에 제공하게 된다.For example, if the reference value is set to 2 atm, when the pressure sensor detects a pressure of 2 atm or less, the control unit generates an rpm rising signal for raising the current rpm of the engine and provides it to the engine.

이후, 블로워의 rpm도 동시에 상승시키는 rpm 상승 신호를 생성하여 블로워에 제공하게 된다.Thereafter, an rpm rising signal that simultaneously raises the rpm of the blower is generated and provided to the blower.

이후, 압력센서에서 감지된 압력값이 1.8기압일 경우에 노면 청소차에 구성된 모든 밸브 닫고, 역분사용 밸브(80)를 열어서 역분사를 소정시간(1분 정도) 시행하고 , 다시 재작동시켜 2기압을 유지하도록 하는 것이다.Then, when the pressure value detected by the pressure sensor is 1.8 atm, all valves configured on the road surface cleaning vehicle are closed, and the reverse injection valve 80 is opened to perform a reverse injection for a predetermined time (about 1 minute), and then re-operated to 2 atm. Is to keep it.
