Abstract

PURPOSE:To enhance washing efficiency by omitting a rotary mechanism, in an apparatus for washing the outer peripheral surface of pillar-shaped or columnar matter, by injecting a washing solution from a slit shaped groove and obliquely setting the jet angle of said washing solution. CONSTITUTION:A ring shaped body 10 is constituted of a combination of an upper ring-shaped member 10A and a lower ring-shaped member 10B. A jet groove 11 is inclined downwardly so as to make the washing solution easy to flow. The high pressure washing solution is guided to a washing solution chamber 13 and injected therefrom in a film form through a jet orifice 11. The washing solution is formed into a downwardly directed umbrella-shaped film to wash the outer peripheral surface of a body 1 to be washed. It is unnecessary to rotate the ring-shaped body and the body 1 to be washed can be washed only by moving said ring-shaped body 10 up and down.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a cleaning device, particularly a columnar cleaning device.

The present invention relates to a cleaning device suitable for cleaning the outer peripheral surface of a cylindrical object.

[Conventional technology]

Conventionally, this type of device has a plurality of cleaning nozzles 2 arranged at equal circumferential positions on a cylindrical object 1 to be cleaned, as shown in FIG. 3, and a rotation mechanism 3 rotates these nozzle rows. Cleaning was performed by vertically moving the nozzle 2 and its rotation mechanism 3 using the up-and-down mechanism 4 while injecting the cleaning liquid supplied from the injection port 5 from the nozzle 2.

However, in such a conventional cleaning device, the trajectory of the cleaning liquid sprayed from the nozzle 2 toward the cylindrical outer circumferential surface of the object 1 to be cleaned has a spiral shape, so that there are parts that are hit by the cleaning liquid and parts that are not hit by the cleaning liquid. However, it has the disadvantage of causing uneven cleaning. In addition, in order to apply the cleaning liquid evenly to the outer circumferential surface of the cylinder,
The feed speed of the up-and-down mechanism 4 must be slowed down, and as a result the cleaning time takes too long.

[Problem that the invention seeks to solve]

The present invention eliminates the above-mentioned conventional drawbacks, eliminates the need for a rotation mechanism, has a simple mechanism, reduces the risk of equipment failure, has low manufacturing costs, and can shorten cleaning time. The purpose is to provide cleaning equipment.

[Means for Solving the Problems] In order to achieve the above object, the present invention moves a cleaning medium relatively along the outer peripheral surface of an object to be cleaned, and during the movement, the cleaning medium is applied to the outer peripheral surface. A cleaning device that performs cleaning by spraying the cleaning medium toward the target object includes an annular cleaning medium passage, an injection slit that can spray the cleaning medium from the entire circumference of the cleaning medium passage toward the outer peripheral surface of the cleaning object, and an annular cleaning medium passage. The apparatus is characterized in that it comprises an annular body having means for supplying cleaning medium to the medium passage.

[Effect]

In the cleaning device configured in this way, the high-pressure cleaning medium is sprayed in the form of a film through the annular medium chamber, that is, the slit-shaped cleaning groove provided inward from the medium passage. Since the spray angle is set obliquely toward the cleaning direction, the columnar outer peripheral surface of the object to be cleaned can be cleaned evenly by simply moving the entire device in the cleaning direction.

〔Example〕

Embodiments of the present invention will be described in detail and specifically below based on the drawings.

FIG. 1 shows one embodiment of the invention. Here, 10 is an annular body, and in this example, the annular body 10 is an upper annular member 10A.
and a lower annular member 10B,
A slit-shaped injection groove 11 is provided in between. 12 is a liquid-tight backing interposed between the upper and lower annular members. Reference numeral 13 denotes a cleaning liquid chamber provided in the circumferential direction of the annular body 10, and an injection groove 11 is provided around the cleaning liquid chamber 13 toward the cleaning space 10C formed inside the annular body 10. The spray grooves 11 are inclined diagonally downward so that the cleaning liquid can easily flow down.

Reference numeral 14 denotes a supply port for supplying cleaning liquid to the cleaning liquid chamber 13, and 15 denotes its supply passage.Although not shown, for example, by connecting a flexible pipe to the supply port 14, high-pressure cleaning liquid is guided to the cleaning liquid chamber 13, and from there. The cleaning liquid can be sprayed in a film form through the slit-shaped spray grooves 11.

Therefore, the cleaning liquid is formed into an umbrella-shaped film facing downward, and the cleaning liquid that collides with the outer circumferential surface of the object to be cleaned 1 always falls downward along that surface, and in the meantime, the dirt is removed downward. This prevents the surface from becoming contaminated again once it has been washed away.

Furthermore, during cleaning, there is no need to rotate the annular body 10 around the object to be cleaned 1, and as shown in FIG. The cleaning liquid injection described above may be performed by moving the annular body 10 or by moving the annular body 10 downward with respect to the object 1 to be cleaned.

In addition, in the above explanation, is the cover of a cylindrical or cylindrical telephone held upright? #r For cleaning, we have described the case where cleaning is carried out by moving the annular body lO in the vertical direction, but the cleaning posture of the object to be cleaned is not limited to this, for example, the annular body lying horizontally is The present invention can also be applied to cases in which the object to be cleaned is moved laterally along the body, and the shape of the object to be cleaned is not limited to a cylindrical shape, but can of course be applied as long as it is columnar.

(Effects of the Invention) As explained above, according to the present invention, high-pressure cleaning medium is ejected from the annular medium chamber provided in the annular body of the cleaning device through the slit-shaped jet provided around the medium chamber. through the groove,
Since the spray is directed towards the cleaning space inside the annular body, simply by moving either the annular body or the cylindrical object to be cleaned relatively in the cleaning direction, the outer peripheral surface of the object to be cleaned can be evenly and uniformly sprayed. To provide a highly reliable and inexpensive cleaning device which can clean objects, has a simple structure, does not require a conventional means of rotating a nozzle around an object to be cleaned, is easy to maintain and inspect. I'm struggling.

Furthermore, by slanting the above-mentioned spray grooves diagonally downward and surrounding them in an umbrella shape, the cleaning medium that collides with the object to be cleaned can always fall downward, thereby removing dirt. By flushing in that direction, it is possible to prevent dirt from adhering to the cleaning surface again.
