Description

[Detailed description of the invention] This invention relates to a surface treatment device that sprays a treatment liquid onto the surface of the object to be treated, such as cleaning, anti-corrosion treatment, or painting. In addition, the processing can be carried out reliably, and the processing liquid is prevented from leaking to the outside of the processing chamber.

When performing surface treatment such as cleaning, anti-corrosion treatment, or painting on an object to be treated, it is necessary to uniformly treat the entire area of the object. If the material is rotated or repeatedly rotated within a predetermined angle, the process inevitably becomes uneven, resulting in an uneven finish.

In addition, although it would be ideal to have a dedicated treatment room for this kind of treatment, in reality this is not always possible, and we have no choice but to partition off a corner of the factory building where other work is being done. Sometimes things are done.

In this case, workers performing other tasks may inhale the components of the processing liquid while breathing, which is extremely undesirable from the standpoint of work hygiene.

This invention is intended to solve these drawbacks and problems at the same time. One embodiment of this invention will be explained with reference to the drawings. First, in FIG. It is surrounded by and formed by.

Inside the processing chamber 1, a riser tube 5 bent into a substantially rectangular shape with only the lower part cut out is supported so as to straddle the object 2, as will be described later. It is possible to reciprocate in the direction perpendicular to the

The riser pipe 5 is provided with a plurality of nozzles 6 facing the object 2 to be processed, and is configured to spray the processing liquid onto the surface of the object 2 with an appropriate pressure.

The riser tube 5 is suspended on both upper sides by a hanger 7 whose central portion is bent into a substantially S-shape, and is reciprocated by a shaft 9 rotated by a motor 8.

To explain this part with reference to FIG. 2, a shaft 9 is rotatably supported at the front and back of the upper outer side of the processing chamber 1 (in the longitudinal direction of the object to be processed 1), and a sprocket (sprocket) attached to this shaft 9 is supported. An endless chino 11 is attached to the .10.

The lower end of a rod 12 is secured to one location of the chino 11 by a pin 13.

The upper end of the rod 12 is connected to a trolley 16 suspended by wheels 15 from a rail 14 provided at the top of the chino 11.
The noho is pivoted to the central part of the coast by pin 17.

Therefore, when the cheno 11 travels in a certain direction, the trolley 16 reciprocates above the processing chamber 1.

The upper end of the hanger 7 described above is attached to the trolley 16.

18 in FIG. 1 is a cover that covers the chino 11 and the like.

Reference numeral 19 in FIG. 1 denotes a connecting pipe, which is made of a pipe material that communicates with a part of the riser pipe 5. It is bent in an S-shape and extends outward through a slit provided horizontally in the longitudinal direction of the partition wall 4. and is connected to the flexible tube 20.

The flexible tube 20 is connected to an iron tube 21 connected to a processing liquid pressure feeding device (not shown).

This flexible tube 20 is interposed between the connecting tube 19 that moves together with the riser tube 5 and the fixed iron tube 21, and therefore has a sufficient length.

Both 22 and 23 are blocking liquid storage boxes provided on the partition wall 4, extending in the direction of movement of the riser tube 5, and filled with blocking liquid 24, 25 such as water or oil.

The upwardly open bent portion formed between the hanger 7 and the connecting tube 19 is immersed in these liquids, and in this state it moves together with the riser tube 5.

Note that 26 and 27 are partition plates that respectively protrude downward from the partition wall 4, and their lower ends are connected to the blocking liquid 24 and 25.
The inside of the processing chamber 1 is isolated from the outside by being immersed therein.

Reference numeral 28 in FIG. 1 is an exhaust pipe whose tip (upper end) extends outside the factory building, and is used to exhaust the inside of the processing chamber 1 by means of a fan device 29 provided inside.

Further, 30 is a chino, which moves the object 2 to be processed to a predetermined position and moves it outside after processing.

In this surface treatment apparatus configured as described above, in order to perform a treatment such as cleaning, anti-corrosion treatment, or painting on the object 2 to be treated, the object 2 to be treated is placed in a predetermined position using the cheno 30, and the cheno 11 is moved. When the riser pipe 5 is run in a certain direction, it reciprocates within a predetermined range, so the riser pipe 5 is connected to the iron pipe 21. When the processing liquid is pumped from a processing liquid pressure feeding device (not shown) through the flexible pipe 20 and the connecting pipe 19, the processing liquid is uniformly sprayed from the nozzle 6 onto the object 2 to be processed.

When the riser tube 5 reciprocates, the hanger 7 and the connecting tube 19 move in the blocking liquid 24, 25, so that the processing chamber 1
The interior and exterior of the processing chamber 1 are completely isolated, and the processing liquid components within the processing chamber 1 do not exit to the outside.

Since this invention is constructed as described above, it has the advantage that processing can be performed uniformly and reliably, and that the processing liquid does not leak to the outside of the processing chamber 1.

Compared to conventional systems that have a large number of fixed nozzles, the number of piping and nozzles can be reduced by 20 to 30%, the capacity of pumps and tanks can be reduced, and the amount of electricity and heat used can also be reduced. be.
