Description

TECHNICAL FIELD [0001] The present invention relates to a dust-reduction type crusher by spraying steam and an inorganic binder, and a method of removing a building using the dust-

The present invention relates to a crusher used in the dismantling of a building, and more particularly to a crusher used in dismantling a building, and more particularly, to prevent dust from being scattered into the atmosphere during demolition of buildings even in the winter season using steam, And a method of removing a building using the dust-reduction type crusher.

Modern society is accelerating urbanization with rapid industrialization. The first thing that comes to mind through such urbanization is the architecture of modern industrialization such as high buildings. In other words, it is no exaggeration to say that most of the modern metropolis is a forest of buildings made of buildings.

Most of these buildings were built for semi-permanent use, but due to rapid social change and economic development in modern society, the useful life of buildings is less than the actual structural life span. Specifically, there is an increasing need to dismantle buildings to build new buildings due to social aspects such as functional aspects of the building, complementary facilities, natural disasters caused by earthquake or fire, and urban redevelopment. In addition, due to rapid social changes and poor construction, lack of safety of buildings, construction of buildings is frequently removed.

As a method for dismantling the building like this, a demolition method using a hand breaker, a steel ball, a water jet, a large breaker, or a crusher is used for a demolition method using mechanized equipment and manpower.

Especially, the method using the crusher is the most suitable for dismantling the buildings and is suitable for dismantling of concrete and steel bar. It is most widely used for demolition of urban area because noise and vibration are comparatively smaller than other methods.

However, when the building is demolished by the conventional method using the crusher, since a large amount of dust is generated and scattered, a large amount of water must be sprinkled at the time of demolishing the building to prevent contamination of the surrounding environment. There is a problem that the cost is increased. In addition, when the building is demolished, there is a problem that the risk of a safety accident is increased because the fragments of the building are scattered around to cause human and material damage.

Nevertheless, since the demolition method by crusher is very efficient, it adopts a technique to prevent the scattering of dust while using crusher.

To prevent the diffusion of dust, fog dust, asbestos, etc. generated in the demolition of buildings into the air, the most representative works can be performed by spraying water on the buildings, and basins, scattered dusts, In order to prevent release to the inside of the building, the worker connects the hose from the water supply pipe to the surrounding area of the demolition site. Thus, there is a considerable problem to prevent the leakage of dust, dust, .

In order to solve these problems, there has been a demand for a water jetting device for preventing the release of air, such as dust and scattered dust, for uniformly spraying water on a large area of a demolition site. A pump having an engine for cultivator was used. The pump with the tiller engine was able to prevent scattering of dust, dust, soil, and asbestos in the air by spraying the structure toward the building rather than the method of spraying directly by the operator. However, It does not seem to have a great effect in comparison to being sprayed.

Also, since the pump and the cultivator engine are separately exposed, there is a problem that considerable noise is generated, which causes frequent complaints from the people around the demolition site. In addition, due to the nature of the engine for cultivating machines, the initial start-up time is considerably long, which causes problems such as increased work time in the demolition site where rapid operation is required, resulting in delayed air and considerable cost loss.

In addition, since the pump and the tiller engine must be provided separately, the use area is large, the mobility and the portability are considerably lowered, the operating cost is increased due to the increase of the fuel cost and the operation cost during operation, And the cultivator engine are operated apart from each other, safety accidents due to careless work by the surrounding workers are frequently generated at high speed rotation.

Patent Document 1 (Japanese Patent No. 10-1196019) discloses a water spray pipe fixing device for installing a water spray pipe on an upper part of a vertical structure provided around a dust zone where dust is generated, comprising: first clamping means fixed to a vertical structure; A second clamping means coupled to the first clamping means and having a water spray pipe coupled thereto; And an angle adjusting unit installed between the second clamping unit and the spray pipe to adjust a rotation angle of the spray pipe, wherein the angle adjusting unit includes: an outer ring fixed to the inside of the second clamping unit; And an inner ring rotatably inserted into the outer ring and having a water pipe connected to the inner periphery thereof.

Patent Document 2 (Registration Utility Model No. 20-0398266) discloses a water supply system including a water supply storage tank installed in an excavator body, water supply means for supplying water stored in the water storage tank to the pressure means, pressure means for pressing the supplied water, A water supply means for supplying water discharged from the means to a sprinkler; and a sprinkler for spraying the water supplied with pressure, wherein the pressure means is installed in an excavator body, the sprinkler being supported by a support member provided on the arm And the water supply means is a dust preventing device for an excavator fixed to a boom and a fixing member provided on the arm.

Although patent literature has the effect of preventing the scattering of dust, when water is frozen when it is used in winter season, it is not sprayed to a distant place due to its inferior activity and it can not prevent scattering of many dusts. The removal rate is very low.

In addition, even if the dust is collected by scattering dust, it is impossible to prevent scattering of dust during transportation of the dust to the transportation vehicle and transportation of the dust to the vehicle, and scattering of the secondary dust occurs, There is no technique to prevent scattering of dust, so it has problems caused by dust.

Patent No. 10-1196019 Registration Utility Model No. 20-0398266

The crusher main body 10 is provided with a driver's seat 12 as a chassis frame and provides a space for installation of the steam injection means 40 and the inorganic binder injection means 50.

The driving unit 11 includes an engine and an endless track (or a wheel) that drives the engine as a driving source to move a demolition site.

Theplating boom 20 moves the position of the crusher 30 to the demolition object and the hydraulic cylinder 23 is hinged with a plurality of booms 21 and 22 (for example, two of them are shown as an example) As shown in Fig.

The hydraulic cylinder 23 is bi-directionally operated by a lever provided on the driver's seat to adjust the position of the crusher 30 by forward and backward movement.

The position of the crusher 30 can be moved forward and backward and the position of the crusher 30 can be swung through the swing frame 20 in order to adjust the left and right position of the crusher 30.

As shown in Fig. 2, the crusher 30 is configured such that the pair of jaws 31 and 32 can crush the demolished object and dismantle the demolished object. For example, each of the pair of jaws 31 and 32 has one end connected to the head block 24 at the front end of the boom 22 and the other end connected to the hinge 33 and 34 through the hydraulic cylinders 35 and 36 Are configured to converge or vice versa and are identical to known crushers.

3, the steam injection means 40 is mounted on the crusher body 10 and mounted on a water tank 41, a crusher body 10 or a water tank 41 in which water is contained, A heater 42 for heating the water contained in the steam boiler 41 and a steam supply pipe 43 for supplying steam generated from the heater 42 to the front end of the boom 20, And a steam nozzle 44 formed at the tip of the steam supply pipe 43 for spraying steam as a demolition object.

The water tank 41 is provided with an inlet for filling water inside and a drain for cleaning. The tank is detachably mounted on the crusher body 10 through an anchor bolt or the like.

The water tank 41 is provided with a thermometer for detecting the temperature of steam, and a temperature gauge is installed on the driver's seat so that the operator of the driver's seat can check the temperature of the steam detected by the thermometer.

The water tank 41 is equipped with a gauge for checking the amount of water.

The heater 42 generates electricity by generating electricity from a generator of a crusher as a heat ray, for example, and generates steam by heating the water stored in the water tank 41.

The on / off operation of the heater 42 is performed by a switch operation of the operator. For example, an on / off switch is provided on the crash pad of the driver's seat.

The heating temperature of the water by the heater 42 is not limited to a numerical value because all temperatures at which water is phase-changed into steam (for example, 80 ° C or more) are possible.

One end of the steam supply pipe 43 is connected to the upper part of the water tank 41 and is supplied with steam generated in the water tank 41. The steam supply pipe 43 is connected to the booms 21 and 22 of theplating boom 20, And is detachably fixed to the boom (21, 22) through the above clamp. The end of the steam supply pipe 43 is fixed to the head block 24 so that the steam nozzle 44 can be installed without shaking.

The steam supply pipe 43 is preferably a flexible rubber hose so as not to be damaged during joint motion of theplating boom 20, and it is also possible to have a wrinkle portion at the joint portion.

The steam nozzle 44 injects the steam supplied through the steam supply pipe 43 to the object to be demolished and the periphery thereof to prevent scattering of dust that is crushed by the crusher 30 and disassembled. For example, It is preferable to spray the steam at a high pressure.

The steam nozzle 43 is installed in the head block 24 without any joint motion, and injects steam at a predetermined area around the demolition object.

The present invention prevents the scattering of dust with high temperature steam and is used effectively in the field of dismantling in the winter, water is frozen due to the external temperature after spraying, the spray area is not wide and the effect of preventing scattering of dust is very weak, Even if the temperature is low, it does not freeze and is sprayed over a large area, and dust is adsorbed through the water, which is excellent in scattering prevention effect.

The steam is sprayed by the operation of the driver, and the driver's seat is equipped with switches such as a steam valve and a compressor switch. The steam valve may be configured in various ways according to the spraying method of the steam. For example, there is a manual injection or an intermittent automatic injection. In the manual injection, steam is sprayed by operating the on- The intermittent automatic injection is a process in which the steam is injected only for a predetermined period of time by the operation of the operator.

As shown in FIG. 4, the inorganic binder injection means is made of an inorganic binder such as a potassium silicate diluent (water: potassium silicate = 9.5 to 10.5: 1 by weight) as an inorganic binder and is mounted on a crusher body 10, A binder supply pipe 52 for supplying a diluted potassium silicate solution stored in the binder tank 51 and a binder supply pipe 52 for supplying diluted potassium silicate solution from the binder tank 51 to the tip end of the boom 20, And a binder nozzle 53 for spraying a diluted potassium silicate solution onto the object to be demolished. The inorganic binder is not limited to a potassium silicate diluent, and various products can be used.

The binder tank 51 is provided with an injection port and a drain port for replenishing the binder and cleaning the inside of the binder tank 51.

The binder tank 51 constitutes a gauge for confirming the amount of the inorganic binder.

The binder supply pipe 52 is piped in the same manner as the steam supply pipe 42, and is made of the same material as the steam supply pipe 42.

The binder nozzle 53 is installed in the head block 24 and always injects the potassium silicate diluent at a high pressure toward the object to be demolished without being interfered with the joint motion, and the pump 54 may be constituted for this purpose. For example, the pump 54 is mounted in the binder tank 51 and operated by the operation of the operator to pump the potassium silicate diluent.

An inorganic binder, which is a potassium silicate diluent, is used as needed and is supplied to the binder nozzle 53 by a binder valve. The binder valve is disposed in the driver's seat and opens and closes the binder supply pipe 52 by operating the operator and adjusts the opening degree of the binder supply pipe 52 to adjust the injection amount of the potassium silicate diluent.

Potassium silicate diluent can be injected manually or intermittently as in steam.

The steam used in the present invention is to prevent dust from being scattered by allowing dust to be adsorbed and fall by gravity, and the inorganic binder binds the dusts to block the secondary dust. That is, when demolishing the demolished object, It is preferable to use only an inorganic binder after dismantling.

Therefore, the steam supply pipe 43, the steam nozzle 44, the binder supply pipe 52, and the binder nozzle 53 can be used independently and can be shared. As shown in FIG. 6, The binder supply pipe 52 of the binder tank 43 and the binder tank 51 are merged into one main supply pipe 56 through the switch valve 55 and the main nozzle 57 is installed at the end of the supply pipe 56. The main supply pipe 56 and the main nozzle 57 are installed in the same manner as described above. Other configurations (steam valves, etc.) are the same as those described above.

The switching valve 55 is driven by the operation of the operator to connect the steam supply pipe 43 and the main supply pipe 56 for steam injection so that steam is sprayed through the main nozzle 57. When the inorganic binder is injected, (52) and the main supply pipe (56) are connected to allow the inorganic binder to be sprayed through the main nozzle (57).

A method of dismantling a building using a dust-reduction type crusher by steam and inorganic binder injection according to the present invention is as follows.

After the crusher of the present invention is transported to the demolition site of the building, the operator moves the demolition site while driving in the driver's seat.

The operator operates the hydraulic cylinders 35 and 36 of the crusher 30 to collect and spread the pair of jaws 31 and 32 so as to crush the demolition object.

When the demolished object is demolished by the crusher 30, dust of concrete is generated. The dust is scattered to the atmosphere under the influence of wind, and environmental pollution due to scattering of dust and the bronchial diseases of workers are caused. Remove.

The operator operates the heater 42 to heat the water stored in the water tank 41 to produce steam.

The steam generated in the water tank 41 is sprayed through the steam supply pipe 43 and then sprayed through the steam nozzle 44. The steam is supplied to the steam nozzle 44, The steam that is sprayed from the steam absorbs the dust by using the characteristic of the water and the dust adsorbed by the steam can not be scattered and falls by the gravity.

The steam can be adsorbed and removed by the steam during the crushing process by the crusher 30 and after the process. Especially, even when the temperature outside the winter season is low, the steam is not affected by the external temperature, So that dust in a wide space is adsorbed and removed.

Meanwhile, the dust that has fallen to the bottom of the demolition site by the steam will be conveyed through the conveying vehicle, and it takes time from the steam injection to the conveying process so that the steam can be evaporated. In other words, It catches scattered dust, but the steam can be removed until the dusting process of the dust, and the dust can be scattered, and the inorganic binder is sprayed so that scattering does not occur even during the transportation of the dust.

When the driver selects the switch of the inorganic binder injection, the potassium silicate diluted solution stored in the binder tank 51 passes through the binder supply pipe 52, is fed to the binder nozzle 53 and is sprayed onto the dust, and the potassium silicate diluent The dusts are bound together and coated so that dust can not be scattered.
