Abstract

The invention relates to the field of cleaning products, in particular the washing of products in drums, and can be used to clean products from various contaminants. The invention makes it possible to reduce the dimensions and improve the quality of cleaning. The connection of the cleaning drums is carried out by means of reloading drums. The cleaning drums are divided into sections by means of partitions, perpendicular to the axis of the drum and having openings. The cleaning drums are provided with a guide blade, made at an angle to the partition, for moving the articles from section to section. The reloading drums are made in the form of a hollow rotation body limited by the partition of the previous drum and the end wall of the subsequent one. The cleaning drums are immersed in the cleaning solution. 4 hp ff, 12 ill.

Description

The invention relates to the field of cleaning products, in particular washing products in drums, and can be used to clean products from fat and mechanical contaminants, as well as to prepare their surface for coating.

The purpose of the invention is to reduce the size and improve the quality of cleaning.

FIG. 1 shows the installation, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - the unit of the reloading drum in the form of a cylinder: in FIG. 5 shows a section B-B in FIG. four; in fig. 6 - node reloading drum in the form of a cone; in fig. 7-12 are the process of moving along the sections of the cleaning and reloading drums.

The installation includes a housing 1 equipped with trays 2 and 3 for loading and unloading products and divided by partitions into baths 4-6 with cleaning solution, an ultrasonic transducer 7 mounted on the bottom of bath 5, heaters installed in baths 4 and 6, a regeneration system and forced circulation

cleaning solution (not shown), located inside the housing 1 and the coaxial cleaning perforated drums 8-10. The drums 8-10 are interconnected by reloading drums 11 coaxially with cleaning drums made in the form of a hollow rotation body limited by the partition 12 of the previous drum and the end wall of the subsequent one. The drums 8 and 9 are immersed in the cleaning solution and divided by partition 12 into sections. The baffles 12 have an opening and a guide vane 13 located at an angle to the partition and intended to move products from section to section. To transfer products from the cleaning drums to the reloading drum, the internal cavities of the cleaning and reloading drums are connected with each other by holes on the side surface of the reloading drums, and in the last sections of the drums 8 and 9 there are bridges 14 fitted to the rear in the direction of rotation.

Pull-edge hole on the intermediate element. For moving the articles along the drum 10, the latter is provided with a helical guide.

The rotation of the drums is carried out with the help of the drive 15. The reloading drum 11 can be made in the shape of a truncated cone, the smaller base of which is limited by the partition of the previous cleaning drum, and the larger one by the end wall of the subsequent drum, or in the form of a cylinder 16 (FIG. 4), inside which is inclined A partition 17 is mounted to the axis of the cylinder to move the products from the reloading drum to the subsequent cleaning drum.

In addition, the drum 11 is provided with a flange 18 (Fig. 6), by which it is attached to a subsequent cleaning drum, and a heat insulating pad 19 is installed between the flange 18 and the end wall of the drum 9.

The installation works as follows.

From the loading device of the product along the loading chute, the first section of the drum 8 enters the guide 13 (Fig. 7). As the drum turns (counterclockwise), the product moves relative to the shell of the latter and through one turn of the drum 8 comes in front of the guide 13. In this moment the next portion of products is loaded. Upon further rotation of the product by means of the guide 13, through the opening in the partition 12, they fall into the second section behind the jumper 14.

After one revolution, the products are positioned in front of the jumper 14 and with further rotation with the help of jumper 14 are reloaded into the reloading drum 11, and through it into the drum 9 for the guide 13.

In the drum 10, the articles are moved by means of a screw guide. After reaching the hole on the side of the drum 10, the products fall into the discharge chute 3 and are discharged from the installation.

By performing a cleaning drum section with partitions and guiding blades, as well as partially inserting the reloading drum into the treatment drum, it is possible to reduce the size of the installation, since compared to transportation by means of an auger, which has a much smaller angle with the same transport step and part of the first section of the drum is not used because of the need to feed products into the drum at a considerable distance from the start of the auger turn, in the invention

the slope of the guide cavity is much larger, which allows the use of the first section of the bottom of the entire portion of the workpiece without additional drum rotation.

Processing time can

adjust by changing the frequency of rotation of the drums, the number of drums, and overload is possible at any ratio of the diameters of the cleaning and transfer drums, which increases the quality of cleaning.
