[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning device that removes foreign matter such as chips and cutting oil attached to a processed work, and more particularly to a high-pressure hot water cleaning device that sprays high-pressure hot water onto the work.

[0002]

[Prior art]

 The conventional high-pressure hot water cleaning device that moves the processed work continuously and injects high-pressure hot water toward the work to clean the work is as follows. A support tool is arranged on a conveyor that moves laterally, and a work to be cleaned is fixed to the support tool. A plate-like wall surface is arranged so as to surround the periphery of the conveyor, and the wall forms a cleaning chamber around the conveyor. On the other hand, an injection nozzle for injecting high-pressure hot water toward the work is arranged in the cleaning chamber. Washing is done by: The work is fixedly placed on the support, and the work moves into the cleaning chamber as the conveyor moves laterally. In the cleaning chamber, high-pressure hot water is sprayed from the spray nozzle toward the center, and the work entering the cleaning chamber is cleaned by the high-pressure hot water sprayed from the spray nozzle. The work washed as described above is moved to the outside of the washing chamber by further moving the conveyor to the side, and the washing is completed after the drying step.

[0003]

[Problems to be solved by the device]

 The conventional high-pressure hot water cleaning device has the following problems. The injection pressure of the high-pressure hot water injected from the injection nozzle toward the work is increased to a high pressure such as 40 kg / cm 2 in order to remove foreign matter. According to this, when this high-pressure fluid is jetted from the jet nozzle, a large jet noise is generated, and this jet noise reverberates on the plate-like wall surface that constitutes the cleaning chamber, producing a loud noise and deteriorating the working environment. Is not preferable. Further, when the injected high-pressure hot water enters the hole, recess, etc. of the work, a collision noise is generated at this part, and the noise is further promoted. The temperature of the high-pressure hot water sprayed from the spray nozzle toward the work reaches 70 degrees, for example. This is necessary to effectively remove the oil such as cutting oil that adheres to the work. When high-pressure hot water is sprayed into the cleaning chamber in this way, the cleaning chamber is filled with steam. If this steam leaks out of the cleaning chamber, it not only deteriorates the work environment, but also disposes around the cleaning device. Give the device trouble. For example, the rust of the device may occur.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a high-pressure hot water cleaning device that causes less noise to the surroundings and less leakage of steam to the outside during cleaning with high-pressure hot water.

[0005]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned object is to arrange the work set on the support on the conveyor and to form a cleaning chamber by surrounding the periphery of the conveyor with a wall surface, and toward the work passing through the cleaning chamber. In a high-pressure hot water cleaning device that cleans a workpiece by spraying high-pressure hot water from a spray nozzle arranged in the cleaning chamber, a plurality of mesh wall members formed by a mesh are arranged inside a wall forming the cleaning chamber with a gap, This is achieved by housing and arranging a cushioning member made of a metal piece in at least a space between a pair of mesh wall members facing each other.

[0006]

[Action]

 The jet noise and the collision noise generated by the high-pressure hot water jetted from the jet nozzle are reduced by the mesh wall member and the cushioning member, and the steam generated by the high-pressure hot water is condensed by contacting the mesh wall member and the cushioning member. Next, the steam disappears.

【Example】

 An embodiment of the high-pressure hot water cleaning device according to the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an apparatus main body having a conveyor 2 that moves laterally, and a wall surface 3 is arranged around the conveyor 2 to form a box-shaped cleaning chamber S. In this example, the wall surface 3 is arranged on the left and right sides and the upper surface in FIG. An inlet opening S1 and an outlet opening S2 are opened in the wall surface 3 on the inlet side and the outlet side of the cleaning chamber S corresponding to the moving direction of the conveyor 2 so that the work W can be moved by the conveyor 2, and further the conveyor 2 A drainage channel 4 is provided at the lower bottom of the apparatus body 1 facing the lower surface of the device. A drain hole 5 is formed in the drain passage 4, and the drain hole 5 is connected to a drain tank 6. A support 7 is fixedly arranged on the conveyor 2, and a work W to be cleaned is set on the support 7. When the conveyor 2 moves laterally, the work W moves laterally together with the support 7. Reference numeral 8 is an injection nozzle for injecting high-pressure hot water (for example, pressure 40 kg / cm 2, temperature 70 ° C.), which is provided with a plurality of injection holes 8 A toward the work W and is in the cleaning chamber S in the moving direction of the conveyor 2. Are arranged along. In this example, the injection nozzles 8 are arranged on the left and right sides and on the upper side. The work W is arranged inside the injection nozzle 8. The above is a conventionally known cleaning device.

Reference numeral 9 is a mesh wall member formed of a mesh, and the mesh wall member 9 is fixed to and integrated with a short-shaped support column 10 whose upper end and lower end extend laterally. A plurality of mesh wall members 9 are arranged with a gap T. In this example, three mesh wall members 9 are arranged as shown in FIG. 3, but the number thereof is appropriately selected. Further, a cushioning member 11 made of a metal piece is housed in a space formed by a gap T between at least a pair of mesh wall members 9 facing each other. The mesh wall member 9 provided with the cushioning member 11 is arranged on the inner surface of the wall surface 3 of the cleaning chamber S. This is arranged by forming a pair of insertion grooves 12 facing each other along the moving direction of the conveyor 2 in a part of each wall surface 3 and inserting the support columns 10 into the insertion grooves 12. According to the above, the mesh wall member 9 provided with the cushioning member 11 is inside the cleaning chamber S, inside the wall surface 3 and outside the ejection nozzle 8.

Next, the operation will be described. When the work W is set on the support 7 on the conveyor 2 and the conveyor 2 is moved, the work W enters the cleaning chamber S through the inlet opening S1 of the cleaning chamber S and is directed toward the work W in the cleaning chamber S. The high-pressure hot water is jetted from the jet holes 8A of the jet nozzle 8 to wash the work W. Then, while the work W moves laterally in the cleaning chamber S by the movement of the conveyor 2, this cleaning is continuously performed, and the work W is discharged from the outlet opening S2 of the cleaning chamber S so that the work W is discharged. The washing of is completed. At the time of cleaning the work W in the cleaning chamber S, the high-pressure hot water sprayed from the spray holes 8A of the spray nozzles 8 fills the cleaning chamber S with steam. By virtue of this, the steam flows through the cleaning chamber S with a great deal of force, and this steam collides with the mesh wall member 9. According to the above, the steam is condensed into droplets by the mesh wall member, and the droplets collectively collect and flow in the drainage channel 4 and are discharged from the drainage holes 5 into the drainage tank 6. Thus, when steam is generated in the cleaning chamber S when the high-pressure hot water is sprayed from the spray holes 8A, this steam is immediately condensed and converted into droplets, and the steam in the cleaning chamber S is effectively converted. Therefore, the steam can be prevented from leaking out of the cleaning chamber S. The mesh of the mesh wall member 9 and the material of the mesh are appropriately selected so that steam is effectively condensed.

On the other hand, according to the high-pressure hot water injected from the injection holes 8 A of the injection nozzle 8, a large noise is generated in the cleaning chamber S due to the injection sound from the injection holes 8 A and the collision of the high-pressure hot water with the work W. However, at this time, the jet noise and the collision noise are attenuated by the mesh wall member and absorbed by the cushioning member 11 housed in the space between the mesh wall members 9, so that the noise can be greatly reduced. It is a thing. It is desirable that the inlet opening S1 and the outlet opening S2 of the cleaning chamber S are as small as possible within a range in which the work W can move.

[0011]

[Effect of device]

 As described above, according to the high-pressure hot water cleaning apparatus of the present invention, steam generated in the cleaning chamber can be effectively eliminated by the mesh wall member, and noise generated in the cleaning chamber can be effectively suppressed by the mesh wall member and the cushioning member. It is possible to provide a high-pressure hot water washing device in which steam does not leak to the outside of the washing room and is quiet.
