Description

[Detailed description of the invention] Industrial application field The present invention relates to a drying device for items to be cleaned that are cleaned using a cleaning liquid, and is particularly suitable for drying items such as motor cores, sintered metal products, radiators, etc. where a large amount of cleaning liquid is applied. This is suitable for cleaning adhered objects to be cleaned.

Conventional technology Conventionally, in drying tanks for drying objects to be cleaned, vaporized gas of attached cleaning liquid generated by heating is released to the outside and is not recovered.
This method requires a large amount of cleaning fluid, which is uneconomical, and also causes pollution when using cleaning fluids that are harmful to the human body.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned drawbacks of the prior art, and aims to collect the vaporized gas of the attached cleaning liquid generated by heating without releasing it to the outside, and to The purpose of this invention is to reduce the consumption of water, to enable economical drying work of items to be washed that is not harmful to the human body, and to perform this drying work efficiently.

Means for solving the problem In order to solve the above-mentioned problems, the present invention
A drying tank equipped with a heating mechanism and used to dry objects to be cleaned that have cleaning liquid attached to them; a discharge pipe that is connected to this drying tank and discharges the vaporized gas of the liquid that has been vaporized by heating; and a cooling device that cools the discharge pipe. It consists of a fan and a cage-like mounting plate that is located above a communication chamber on the suction side of the cooling fan and pre-dries the objects to be cleaned.

Operation In the device configured as described above, the object to be cleaned, which has been cleaned in the previous step and has the cleaning liquid attached to it, is placed on the mounting plate, and the outside air sucked by the cooling fan and flowing into the communication chamber is heated. After preliminary drying, it is inserted into a drying tank and heated by a heating mechanism, so that the cleaning liquid adhering to the object to be cleaned is evaporated and the object to be cleaned is dried. If the interior of the drying tank is connected only to the exhaust pipe in this state, the vaporized gas will flow into the exhaust pipe, be cooled by the cooling fan, condensed and liquefied, and recovered as a cleaning liquid.

Embodiment The present invention eliminates the above-mentioned drawbacks, and one embodiment of the present invention will be explained below with reference to the drawings. A heating mechanism 4 such as an infrared lamp or a heating heater is provided to heat and dry the object 5 that has been cleaned. The object to be cleaned 5 may be one with little cleaning liquid attached, but may be a sintered metal product,
It is particularly effective for radiators made of many stacked plates, motor cores, etc., which are subject to a large amount of cleaning fluid. Reference numeral 6 designates a discharge pipe having one end connected to the central part of the conical lower wall 7 of the drying tank 1. The discharge pipe is formed in a spiral shape and the other end is connected to the storage part 9 for the cleaning liquid 8. The vaporized gas of the vaporized adhering cleaning liquid is extracted. Reference numeral 11 denotes a cooling fan for cooling the exhaust pipe 6 that brings out this vaporized gas;
The open end 16 of a suction pipe 15, which is fixed to the support punch 13 of No. 2 and connected in the direction in which the discharge pipe 6 is led out via a valve 14, is positioned facing the suction side. Reference numeral 17 denotes a screen-like mounting plate provided at the upper end of the main body 12 located on the suction side of the cooling fan 11, which is connected to the cooling fan 11 through a communication chamber 18, and is used to hold the objects 19 to be cleaned before being inserted into the drying tank 1. Obi cooling fan 1
Pre-drying is performed using the suction power of 1.

In the above-mentioned structure, the object 5 to be cleaned, which has been cleaned in the previous step and has the cleaning liquid attached thereto, is placed on the placement plate 1.
When the object (5) is placed on the drying tank 7 and pre-dried by the outside air sucked in by the cooling fan 11 and flowing into the communication chamber 18, it is inserted into the drying tank 1 and heated by the heating mechanism 4, where the cleaning liquid adhering to the object (5) is vaporized and evaporated, and the object (5) is dried. If the lid 3 is sealed in this state, the vaporized gas flows into the exhaust pipe 6, where it is cooled by the cooling fan 11, condensed and liquefied, and collected in the storage section 9 as the cleaning liquid 8. Also, as shown in the above embodiment, the suction pipe 15 connected to the outlet side of the exhaust pipe 6
If the open end 16 of the exhaust pipe 6 is positioned so as to face the suction side of the cooling fan 11, a suction force acts on the outlet side of the exhaust pipe 6, making it possible to quickly suck the vaporized gas in the drying tank 1 into the exhaust pipe 6. The connection of the suction pipe 15 to the exhaust pipe 6 must be made at a point where cooling by the cooling fan 11 has been completed and condensation of the vaporized gas has been completed.

Effects of the invention With this invention, the cleaning liquid vaporized in the drying tank can be reliably condensed and recovered, making it possible to perform economical cleaning work on objects to be cleaned that have a large amount of cleaning liquid attached. At the same time, it is possible to prevent the cleaning solution solvent from diffusing into the atmosphere, which conventionally occurs, and eliminate the risk of pollution. In addition, the items to be cleaned that are to be dried in the drying tank can be pre-dried by placing them on a screen-like mounting plate, which speeds up the drying time in the drying tank. Since this pre-drying utilizes the suction force of a cooling fan, no special energy is required for pre-drying, making it possible to dry the items to be cleaned economically and efficiently.
