Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit-type cooling pipe cleaning apparatus provided with a replaceable branch pipe unit so as to easily meet various cleaning needs.

[0002]

2. Description of the Related Art If a cooling path of a mold or a cooling pipe of an air conditioner has been used for a long time, rust is generated inside the pipe or scale such as calcium or silica adheres, and the inside of the pipe becomes narrow, resulting in cooling. The effect may be reduced. Therefore, rust generated on these cooling passages and cooling pipes and attached scales have been conventionally removed by using a cleaning liquid by a cleaning device.

FIG. 4 is a block diagram for explaining a cooling pipe cleaning apparatus 1 of a conventional apparatus. Cooling pipe cleaning device 1
Is composed of a storage tank 2 for storing the cleaning liquid, a pump 3 for supplying the cleaning liquid, a filter 4 for filtering the cleaning liquid, a pressure gauge 5 and a flow meter 6, and the like. I have.

When cleaning the cooling passage 21 of the mold 20, first, the cleaning liquid is put into the storage tank 2, and the cooling passage 21 of the mold 20 and the cooling pipe cleaning device 1 are connected to the connecting pipe 1 on the cleaning liquid supply side.
2 and a connecting pipe 13 on the washing liquid recovery side. Stopper 8,
When the pump 9 is opened and the pump 3 is operated, the cleaning liquid circulates through the cooling passage 21 of the mold 20 to perform cleaning. The washing condition can be monitored by the pressure gauge 5 and the flow meter 6, and after washing, the drain plug 7 is opened and the washing liquid can be collected.

[0005] When there are a plurality of cooling water passages 21 of the mold 20 or when it is desired to wash a plurality of molds 20 at the same time, a branch pipe for branching the washing liquid to be supplied to the mold 20 and a branched washing liquid are supplied. A collecting pipe to be assembled is separately prepared, and connected to the connecting pipe 12 and the connecting pipe 13 for cleaning.

[0006]

However, the conventional cooling pipe cleaning apparatus 1 has the following problems.

When the mold 20 having a plurality of cooling passages 21 is to be washed, or when a plurality of molds 20 are to be washed at the same time, a plurality of cooling passages 21 can be connected in series for washing. As described above, the branch pipe and the collecting pipe are prepared separately from the cooling pipe cleaning apparatus 1 and connected to the cooling pipe cleaning apparatus 1 for cleaning, as described above. Therefore, separate devices must be prepared, and the entire device is bulky, requiring a lot of space in a washing place, and there is a fear that handling becomes complicated.

In order to require a large amount of space in the washing place and to avoid complicated handling, it is conceivable to incorporate a branch pipe branching from a washing liquid channel into an integrated apparatus. Since cleaning needs are diversified over a wide range, it is necessary to prepare various types of cooling pipe cleaning devices in order to meet those needs individually, which may increase costs. Furthermore, even if a product suitable for the purpose is prepared, its use is limited, so that it may not be possible to cope with a change in cleaning needs.

[0009] The present invention has been made in view of the above, and an object of the present invention is to provide a unit-type cooling pipe cleaning apparatus excellent in operability that can easily respond to various cleaning needs.

[0010]

2C shows a multi-channel branch pipe unit 50c, FIG. 2D shows a branch pipe unit 50d capable of switching backflow, and FIG. 2E shows a pressure gauge 35 on the branch pipe.
And a branch pipe unit 50e to which a flow meter 36 is attached so as to enable reverse flow. Branch pipe units 50a, 50
b, 50c, 50d, 50e are branch pipe parts 51a, 51b, 51c, 51d, 51e having a plurality of plugs 54,
Collecting pipe sections 52a, 52b, 52 having a plurality of plugs 54
c, 52d, and 52e, and can be mounted and replaced according to various cleaning needs.

The branch pipe unit 50a shown in FIG. 2A is capable of supplying a cleaning liquid in parallel to the cooling path when the mold 60 has a relatively small number of cooling paths, thereby improving the cleaning effect. The branch pipe unit 50b in FIG. 2B is particularly effective when it is desired to monitor the cleaning state for each cooling path of the mold 60 and perform cleaning. The branch pipe unit 50c of FIG.
Is effective when the number of cooling paths of the mold 60 is relatively large or when it is desired to wash a plurality of molds 60 at the same time. The branch pipe unit 50d in FIG. 2 (D) includes a switching unit 53, and is particularly effective when it is desired to perform cleaning by performing reverse flow switching of the cleaning liquid. In the switching unit 53, when supplying the cleaning liquid in the forward direction, the stoppers 55g, 55g
h and the plugs 55f and 55i are opened, and when supplying the cleaning liquid in the opposite direction, the plugs 55g and 55h are opened and the plugs 55f and 55i are opened.
Close i. The branch pipe unit 50e shown in FIG.
Is particularly effective when the cleaning state is monitored for each cooling path of the mold 60 and a switching section 53 is provided to perform cleaning by performing reverse switching of the cleaning liquid. In the switching unit 53, when supplying the cleaning liquid in the forward direction, the stopper 55 is used.
g and 55h are closed and the stoppers 55f and 55i are opened. When the cleaning liquid is supplied in the opposite direction, the stoppers 55g and 55h are opened and the stoppers 55g and 55i are opened.
f, 55i is closed. The backflow switching can be attached to the main unit 1, but since it may not be used, it can be said that attaching it to the branch pipe unit 50 is effective.

FIG. 3 shows the main unit 31 and the branch pipe unit 5.
1 is an external view of a unit-type cooling-pipe cleaning apparatus 30 in which a housing 0 is disposed in a housing 40. FIG. 3A shows an internal side view of the housing 40 of the unit-type cooling pipe cleaning device 30, and FIG.
(B) shows a front view of the housing 40 of the unit-type cooling pipe cleaning device. As shown in FIG. 3A, a branch pipe unit 50, a storage tank 32, a pump 33, a filter 3
4, a pressure gauge 35, a flow meter 36 and the like are provided. A display 70 and operation switches 60 such as a pump 33 are provided on the front of the housing 40 shown in FIG. The pressure gauge 35 and the flow meter 36 can be directly measured visually, but data can also be displayed on a display 70, and the opening and closing of the stopper 37, the stopper 38, the stopper 39 (shown in FIG. 1) and the stopper 54 can be performed. Although it can be performed manually, an operation switch may be provided on the housing 40 as an electromagnetic valve to be operated.

In the above embodiment, the cleaning of the cooling passage of the mold has been described, but the cleaning of the piping of the air conditioner can also be performed.
