Description

one

The invention relates to devices for spraying liquids, for example, melts of nitroammophos, nitroammophosh when granulating them.

The spraying of substances that may contain inclusions in the form of solid particles, such as potassium chloride, phosphogypsum, irp by means of known centrifugal rotating sprinklers having perforation of the wall, is difficult due to frequent clogging of the outflow and formation of buildup of crusts on the walls.

A device for spraying 1 J containing a rotating hollow perforated cone is known, in which a device for cutting the crust is placed, mounted either stationary or rotatably with respect to the walls of the sprinkler.

The device for cutting the crust can be in the form of a radially mounted knife or can be made in the form of a scraper of a certain profile moving along a screw groove cut through the inner wall of the sprinkler.

The disadvantages of this device are the complexity of the design as a whole, the increased intensity and power consumption. In addition, the granule 10 metric composition of the resulting product contains an increased amount of fines, which impairs its properties during storage and application to the soil.

The closest to the described invention to the technical essence and the achieved result is a device for spraying liquids 2, containing rotating

20 perforated shell, on the outer surface of which baffle elements are installed, some of which are made in the form of rings with bent

edges, and a feeder with a pipe

The disadvantage of this design is the preparation of small-sized droplets (granules), which impairs the properties of the product during storage and its effectiveness when applied to the soil. The aim of the invention is to increase the yield of large granules in the product to be obtained.

This goal is achieved by the fact that in the proposed device for. spraying liquids, predominantly rasplavov, containing rotating perforated casing, filled up with a branch pipe for introducing liquid and fender elements fixed on its outer surface, made in the form of rings with bent edges, outer surface of bent edges of the rings of a hinge and grooves on it, executed pr rezi.

FIG. 1 shows a general view of the device; in fig. 2 shows a breaker element in the form of grooves; in fig. 3 that kind of slots.

The device contains a rotating perforated shell 1, baffle elements 2, a coupling .. 3 shaft t, a feeder 5, a nipple 6 for inlet, a melt, slots 8.. The device works as follows.

The liquid enters the rotating perforated shell 1 through the liquid inlet 6 and the feeder 5. The device rotates with the shaft k and the coupling 3. Through the holes in the perforated shell, the melt is thrown onto the inner cylindrical surface of the baffle elements and falls to their lower rounded edges. With the help of an outer rounded edge of the fender element, the melt flows onto its outer cylindrical surface with which it breaks down in the form of a film. The grooves 7 and the slits 8 (Fig. 2) ensure the separation of the film in case of a breakdown into parts of equal size, which form jets disintegrating into potassium with a small amount of small fraction.

A device with a capacity of 2.5 was tested on a model fluid having a viscosity of 50100 spois. The perforated shell is made in the form of a truncated cone (the diameter of the upper base is 1 And 0 mm, the diameter of the lower base is mm, the height is 1bO mm). The diameter of the outflow openings is 5 mm, which contributes to the practical elimination of their blockage by solid particles contained in the water and having a diameter of 1-1.5 mm. On the outer surface of the perforated cone, 7 baffle elements are installed. Combs in the form of discs with diameters from 1 dB dd 135 mm, having a height of the cylindrical part of 30 mm, outer edges

the outer cylindrical surface is rounded and grooves are located on it, as shown in FIG. 2, the size of the ZR mm. The rotational speed of the device is rpm. As a result of the expansion of the spraying device, droplets with an average diameter of 2 mm and a content of fines (less than 1 mm) in an amount of 1-3 were obtained. If additional through-cuts are made on the outer surface of the lower edge of the discs, then in the case of splashing high-viscosity liquids with a viscosity of 150 spois, a product of a homogeneous granite is obtained. va containing small droplets

(granules) 1-3.
