Description

The invention relates to means for cleaning hollow products, it will find direct application when cleaning vessels with a narrow inlet from a solid solid mass.

The purpose of the invention is to simplify the design and improve ease of use.

Removal of a solid solid mass from vessels with a narrow neck is achieved by that. that each cleaning tool is made in the form of two articulated strips, at least one of the free ends of which interacts with the drive shaft movably along the axis to form a hinged four-link bar with the other cleaning tool.

The goal is achieved by those. that the drive shaft is made with flats mating with cleaning strips, the edges of which are oriented towards the walls of the cylinder, are made with teeth. The goal is also achieved by those. that the free ends of the strips, movably interacting with the drive shaft, are connected to the latter by means of a hinge that moves in a groove made in the drive shaft along its axis.

In the known technical solutions, there are no cleaning tools capable of penetrating into a solid mass and automatically monotonously increasing the working area due to two degrees of freedom (the movement of the strips is reciprocating and rotary). Those. the opening of cleaning tools occurs not only under the action of centrifugal forces, but also largely due to the force of the longitudinal feed, forcing the opening of the strips.

FIG. 1 shows the device:; Fig. 2 - device in a static state; in fig. 3 - section B-B in fig? \ 2.

The proposed device contains a drive shaft 1 with a working member 2, consisting of ^

4. The shaft is made with flats 5, channel A for supplying fluid (air, liquid) and a groove 6, in which the hinge is located

7.

To remove the solid mass of the filler from the balloon, the working body 2 in the folded state is introduced into the neck of the balloon and sequentially rotated at low speed and feed along the axis, like a conventional drill, the channel is drilled in the filler for almost the entire length of the balloon. In this case, through channel A, for example, compressed air is supplied, with the help of which the crushed mass is blown out of the cylinder. In the process of introducing the working body 2 into a solid mass, the latter creates a certain reaction as a reaction to longitudinal movement. Frontal, with respect to the solid mass, the strips 3 together with the hinge 7 begin to move along the groove towards the neck. In this case, the 4 hinged strips form a rhombus shape. With an increase in the speed of rotation of the drive shaft 1, the centrifugal forces intensively open the strips 3, thereby the initially formed channel in the solid mass of the filler expands and this occurs until the apex of the angle of the mating strips 3 reaches the walls of the cylinder. Moving the working body 2 along the axis of the cylinder, it is cleaned. In this case, the destroyed particles of the filler mass are removed with compressed air.

Then they are regenerated for use again when filling the cylinders. The dimensions of the strips are naturally proportional to the dimensions of the inner volume of the balloon. At the bottom of the spherical shoe of the cylinder and in its upper part of the spherical head, the corresponding strips occupy the position of the chord of the circle, and very close to the spherical surface. As a result, the surface is cleaned to the maximum extent. Complete removal of the filler mass in a hard-to-reach place (in the area of the inlet) is performed manually by introducing the well-known curved brushes, washing with a stream of water under pressure and blowing with compressed air. At the end of cleaning, the rotation of the shaft 1 stops and the working body 2 is removed from the cylinder cavity. At the same time, the rear strips 3, meeting with the body of the cylinder near the hole, experience natural resistance. The reaction of interaction is transmitted through the slats 3 to the hinge 4, around which the slats 3 are rotated by folding along the axis. In such a folded state (Fig. 2), the working member 2 is easily removed from the cavity of the balloon. For compactness, with the aim of easier insertion (output) of the working body 2 into the neck of the cylinder, the drive shaft 1 is made with flats 5. Along them, strips 3 are laid, which practically can not go beyond the dimensions of the drive shaft (section B-B in Fig. 3).

The proposal provides for the expansion of technological capabilities in operation due to drilling of a solid mass of aggregate by forcible introduction of a working body into it on one side, and on the other due to automatic opening of the strips 3 from centrifugal forces.
