Description

Detailed Description of the Invention

Field of Invention

The present invention relates to cleaning industrial products such as metal processed products and plastic molded products, and articles to be cleaned such as foods, fruits, and cereal foods.

In conventional cleaning operations, most of the cleaning products are put in a large amount of cleaning products at the same time and cleaned at the same time. For this reason, the permeability of the cleaning liquid and cedar liquid to the overlapping parts of the cleaning product is poor, and to compensate for these drawbacks, the cleaning product is shaken, the separation of the cleaning product by rotation, and the external force such as ultrasonic waves is applied. We are striving to improve. Also in drying, a vacuum drying apparatus using a vacuum apparatus is necessary to improve drying characteristics. For the recycling and recycling of cleaning solutions for environmental measures, a separate recycling / recycling device must be prepared in the cleaning tank due to the mechanism for the simultaneous cleaning of large quantities of cleaning products using cleaning basins. In addition, it is inevitable that scratches and deformations occur due to collisions between the washed items.

Further, in order to shift from the cleaning process to the drying process in the conventional rotating drum type cleaning device, for example, the rotating drum is inclined upward and the cleaning product is floated from the cleaning tank while being sent in the rotating drum, and drained and dried. I was doing. However, depending on the size and shape of the cleaning product, there is a problem that the cleaning product falls in the middle of feeding due to the inclination of the feed fin, causing deformation and darning. Due to the inclination, the length of the rotating drum is limited, and the size and shape of the cleaning product are limited.

Problems to be solved by the invention

In so-called batch-type cleaning, in which a large amount of cleaning products are placed in a cleaning tank in a cleaning tank, and cleaning and drying are performed, the cleaning products and cedar liquids have poor permeability due to the overlapping of the cleaning products. However, poor drying also occurs during drying. Moreover, deformation, scratches, and dry spots are likely to occur due to collisions between the washed items.

Industrial disposal of used cleaning liquid leads to an increase in cleaning costs and environmental destruction. For this reason, the cleaning liquid is recycled and recycled. For cleaning and recycling of the cleaning liquid for cleaning in the cleaning tank and drying in the drying tank, a recycling and recycling apparatus must be prepared separately. For this reason, it becomes inevitable that it becomes a large cleaning device with a complicated structure.

Due to the nature of the rotating drum system, it was necessary to incline the rotating drum upward and float it from the washing tank in order to perform liquid drying. For this reason, the cleaning method is also limited to immersion cleaning. Also, because the feed fins were tilted, the cleaning product dropped and scratched. Due to the mechanism of tilting the rotating drum, the length of the drum is limited, and in order to satisfy all, a complicated structure and an increase in size are inevitable.

Means for solving the problem

The cleaning apparatus according to claim 1 has a rotating shaft as a rotating shaft, and forms a substantially cylindrical cleaning rotating drum and a draining rotating drum connected to the rotating drum, and is continuously connected to the inner peripheral surface. A device having a drive device that forms a spiral feed fin and rotates along a rotation axis is used as a cleaning function device, and a substantially cylindrical cedar rotary drum, and a draining rotary drum and a drying rotary drum connected to the drum. A device having a rotation driving device that continuously forms a spiral feed fin on the inner peripheral surface and rotates it along the rotation axis is referred to as a cedar drying function device. A part of the tip of the rotary drum for draining the cleaning function device is connected to the cedar function device so that the cleaning product can be delivered. A cleaning apparatus according to a second aspect of the present invention reduces the tip of the draining rotary drum according to the first aspect to a tapered shape, and returns the cleaning liquid and the cedar liquid to the cleaning product inlet. The cleaning product is characterized in that high-precision cleaning accuracy is obtained because cleaning or cedar is performed while the cleaning liquid or cedar liquid is sent in a clean direction. Further, since cleaning, cedar, and drying are performed on the basis of the horizontal axis, there is a feature that there is no restriction due to the size and shape of the cleaning product and there is no occurrence of scratch deformation. .

In the cedar rotating drum, the cleaning liquid in the cleaning liquid tank is heated in a vapor state from the cedar liquid injection nozzle by a heating device to perform steam cedar cleaning. A cooling device is formed on the outer peripheral surface of the cedar rotary drum and in the drum, and the cedar steam is cooled and liquefied, and returned to the tank as purified cedar liquid. Since the washed product is washed at a high temperature, the adhering material is easily melted and removed, thereby facilitating the washing. Further, the steamed cedar guarantees a high-precision washing accuracy by cleaning the washed product.

As described in claim 5 in the cleaning apparatus according to claim 1 and claim 2, a fixed amount of purified cedar liquid is taken out, a fixed amount of cleaning agent is added, and returned to the cleaning liquid tank as a constant concentration cleaning liquid. It is characterized by things.

The cleaning conditions can be changed according to the performance of the deposits on the cleaning product, and appropriate cleaning accuracy can be obtained.

Since one or a few are washed, the washing liquid and the cedar liquid in the washing article have good permeability, and the washing article is fed while being swung by feed rotation friction during the washing article transfer. The oil adhering to the cleaning product is improved in fluidity with a high-temperature cleaning liquid or a high-temperature or steam cedar liquid, and combined with the cleaning performance of the cleaning liquid, an efficient precision cleaning can be performed.

Since the cleaning rotary drum and the cedar rotary drum are used and cleaning and cedar are performed in the drum as described in claim 5, high-temperature cleaning and steam cedar can be safely employed. This steam not only increases the cleanliness and cleaning accuracy of the product to be cleaned, but also liquefies by cooling to produce purified cedar liquid. By returning to the cleaning liquid tank, a cleaning liquid regeneration cycle can be achieved. A single washing improves the washing performance and at the same time has a characteristic that the washing cycle can be a washing liquid regeneration cycle. It is possible to reduce the size and price of the equipment. A cleaning device that is also effective for environmental conservation measures.
