(54) CYLINDRICAL SOLUTIONS CLEANER

I

The invention relates to devices for cleaning cylindrical sieves and can be used in chemical, mining, agriculture.

Known cleaner, inclusive block, made in the form of a closed loop C-1L.

The disadvantage of this cleaner is the poor quality of the cleaning of the sieves, due to the low relative speed of movement of the brushes on the sieve; the complexity of manufacturing the cleaner due to the presence of hair brushes (working and supporting hair bundles must be definitely oriented along the surface of the pad, which complicates the process of inserting hair into the block); rapid wear of the hair bundles, and, therefore, frequent replacement of the working bodies.

The aim of the invention is to improve the quality of cleaning horizontal vibration-centrifugal sieves, increase the reliability of the cleaner and simplify its design.

The goal is achieved by the fact that the pads are made in a closed circuit with radial holes and are installed around the sieve with a gap to it, the pads having a U-shaped form, and the radial holes have a rectangular form.

A cleaner is a set of such pads installed loosely on a cylindrical screen.

FIG. 1 is a schematic diagram of a cleaner; in fig. 2 is a schematic diagram of a cleaner block; FIG. 3 shows a kinematic diagram of the advancement of the ring pad of the purifier during its operation.

The cleaner consists of a set of blocks I, mounted captively on a cylindrical sieve 2. The sieve rotates on a spring-loaded axis 3, which oscillates. A prerequisite for the operation of the cleaner is the presence of radial components of the oscillation amplitude.

The pads contain holes 4 for the exit of the passage fraction and working platforms 5, which are in contact with the sieve to be cleaned.

The sieve cleaning process occurs as follows.

The radial sieve oscillations along a certain path lead to the displacement of the center of gravity of the pad 1 around the axis 3 of the sieve 2 with the same frequency.

With this movement, the pads are cut off around the outer diameter of the sieve and the stuck particles of the material being processed are pushed by the working planes 5 at the points of contact into the sieve. The by-pass fraction of the material being processed is by inertia vybrasyvatsya through the holes 4 out.,,

The proposed cleaner is not difficult to manufacture, does not require expensive materials (the cleaner's pads can be made of plastic) and is highly durable compared to brush cleaners.

The use of the proposed sieve cleaner in a grain cleaning machine with a vibration-centrifugal sieve will give an annual economic effect of 2940 rubles.
