Description

[Detailed Description of the Invention] This invention relates to an improvement of a parts washer used to remove oil, fat, dust, etc. adhering to mechanical parts during maintenance and maintenance work of mechanical equipment.

Conventionally, the cleaning work of parts that is commonly performed is
In many cases, parts were washed by hand by spraying high-pressure water or cleaning oil, but it took a long time to completely remove the oils and the oils could scatter or leak. There were many problems, such as deterioration of the environment. Furthermore, a parts washer is known in which parts to be cleaned are placed in a cleaning basket that moves up and down in a cleaning tank, but no measures have been taken to deal with when the cleaning liquid in the cleaning tank becomes dirty.

The present invention has been made for the purpose of providing a parts washer that can clean parts without these drawbacks, and will be explained below based on the drawings.

The drawing is a partially cutaway perspective view showing an embodiment of the parts washer of the present invention.

In the figure, a cleaning tank 1 consists of a box-shaped main body 2 and a lid 3 on the top thereof which can be attached or detached as necessary, and the main body 2 stores a cleaning liquid during a cleaning operation. A part of the main body 2 of the cleaning tank 1 is a small box-shaped floating matter guide chamber 11, and the inside thereof is divided into an upper chamber and a lower chamber by a horizontal plate. In the illustrated embodiment, the floating matter guide chamber 11 is provided so as to protrude outward from the main body 2 of the cleaning tank 1, but it may also be provided in a part of the interior of the main body 2.

A separation tank 9 and a pump chamber 17 are provided adjacent to the main body 2 of the cleaning tank 1. The separation tank 9 is divided into an upper chamber and a lower chamber by a mesh plate 10, and the lower chamber and the lower part of the pump chamber 17 are opened and communicated with each other. The separation tank 9 and the pump chamber 17 may be provided by partitioning a part of the main body 2 of the cleaning tank 1.
In the illustrated embodiment, the pump chamber 17 is provided by partitioning a part of the main body 2. A floating matter removal valve 16 is attached to the outside of the separation tank 9. In addition, the separation tank 9 has a double box shape as shown in the figure,
It is also possible to make it possible to remove only the inner box.

Inside the pump chamber 17, an air lift pump 7 is provided which sucks up the cleaning liquid at the lower part of the pump chamber 17 using air sent from the air pipe 8 and sends it to the upper part of the cleaning tank main body 2. The upper chamber of the separation tank 9 communicates with the upper chamber of the floating matter guide chamber 11 provided in the cleaning tank body 2 through a horizontal communication pipe 13. Through this horizontal communication pipe 13, the cleaning liquid with floating substances flows into the separation tank 9 from the floating substance guide chamber 11. It is preferable that the horizontal communication pipe 13 is provided with a flow rate adjustment valve 12 so that the flow rate of the cleaning liquid can be adjusted as desired. Further, it is desirable that the lower chamber of the floating matter guide chamber 11 and the lower chamber of the separation tank 9 are also communicated through a horizontal communication pipe 15 having a flow rate regulating valve 14. Thereby, the cleaning liquid without floating substances in the lower chamber of the floating substance guide chamber 11 can also directly flow into the lower chamber of the separation tank 9.

Further, at the bottom of the cleaning tank body 2, a cleaning liquid heater 6 formed of an electric heating element, a steam coil, or the like is provided. Note that a rail 5 is provided on the bottom surface of the cleaning tank main body 2, and a parts loading cart 4 on which parts to be cleaned are placed is installed on the rail 5 so as to be horizontally reciprocating.

The parts washing machine of the present invention is constructed as described above, and when cleaning parts using this machine, it is carried out as follows. First, the parts to be cleaned are placed on the trolley 4, and appropriate amounts of water and cleaning agent are poured into the cleaning tank body 2, pump chamber 17, and separation tank 9. Commercially available cleaning agents may be used. A cleaning liquid made by diluting the cleaning agent with water is heated by the cleaning liquid heater 6, and when the temperature reaches an appropriate temperature, a cart driving device (not shown) is driven to transport the parts loading cart 4 on which the parts to be cleaned are placed. horizontally reciprocate. In this way, oils and fats adhering to the parts to be cleaned are peeled off by sliding between the cleaning liquid and the parts surface, and float to the upper surface of the liquid to become floating substances.

At this time, when air is sent into the air pipe 8 and the air lift pump 7 is operated, the cleaning liquid in the pump chamber 17 is sent into the main body 2 of the cleaning tank 1.
Then, since the lower part of the pump chamber 17 and the lower chamber of the separation tank 9 are in communication, the liquid in the separation tank 9 descends, and floating objects such as oils and fats floating on the upper surface of the liquid in the cleaning tank body 2 are removed. The material enters the upper chamber of the separation tank 9 from the upper chamber of the material guide chamber 11 through the horizontal communication pipe 13. In this case, if the amount of the cleaning liquid is adjusted so that the upper surface of the cleaning liquid matches the middle of the horizontal communication pipe 13, the suspended matter will flow into the upper chamber of the separation tank 9 without staying in the floating matter guide chamber 11. It is preferable that it can be done. The floating matter that has entered the upper chamber of the separation tank 9 in this way is removed from the mesh plate 1.
The water is filtered by 0, becomes clean cleaning liquid in the lower chamber, and enters the pump chamber 17.

In this way, the cleaning liquid is circulated between the cleaning tank main body 2 → suspended matter guide chamber 11 → separation tank 9 → pump chamber 17 → cleaning tank main body 2 by the action of the air lift pump 7, and is cleaned every time it passes through the separation tank 9. be done. Floating substances such as oils and fats accumulated in the upper chamber of the separation tank 9 can be taken out by opening the floating substance removal valve 16 provided in the separation tank 9, or if the separation tank 9 is configured in a double box shape as described above. If so, it can be easily removed by removing the inner box. Note that the circulation speed of the cleaning liquid can be adjusted by adjusting the amount of air sent into the air pipe 8 and the opening degree of the flow rate adjustment valve 12.
It can be arbitrarily selected depending on the degree of dirt on the parts.

As mentioned above, the parts washer according to the present invention is a parts washer in which the parts to be cleaned are placed on a cart that repeatedly moves back and forth in the horizontal direction within a cleaning tank filled with cleaning liquid, and a separation tank is provided beside the cleaning tank 1. 9 and a pump chamber 17, the separating tank 9 is divided into an upper chamber and a lower chamber by a mesh plate 10 disposed in the middle part, and a passage is provided to connect the lower part of the lower chamber and the lower part of the pump chamber 17, Further, a horizontal communication pipe 13 is provided between the upper chamber provided next to the cleaning tank 1 and the upper chamber of the separation tank 9, and the horizontal communication pipe 13 is arranged so that the liquid level is in the middle.
A flow rate regulating valve 12 is provided in the tank 1, and an air lift pump 7 is provided to send the cleaning liquid from the lower part of the pump chamber 17 to the upper part of the cleaning tank 1.

If the parts washer of the present invention is used, work efficiency will be greatly improved due to the following effects, making it an extremely useful device for on-site work.

(b) No human labor is required during parts cleaning work.

(b) Cleaning work time is significantly reduced.

(c) Due to the action of the separation tank, the cleaning solution can be reused permanently, reducing material costs.

(d) If the cleaning tank body is covered, the cleaning liquid will not be scattered, and a ventilation system for discharging fumes will be unnecessary, making the working environment much better.
