Description

(54) DISK SPRAYER

This invention relates to a suspension spraying technique and can be used in centrifugal rotary dispensers nf ' s production of fodder yeast in reptiles. alcohol and pulp and paper industry.

A sprayer is known, comprising a housing with a snail-shaped chamber made therein, spray sleeves, a rotating insert with a spiral partition and a disk with sharp partitions Y

However, there are no conditions for drying the product after it has left the spray edge in the flare plane: 1 H, which results in large dimensions of the drying chamber in diameter and height.

A disk sprayer is also known, the upper disc coaxially arranged and mounted on the drive shaft are the lower spray disc with blades mn from its working surface and with a spraying edge protruding beyond the edge of the upper disc; coolant supply (2)

This device is the closest to the invention in technical sense and the achieved result.

The aim of the invention is to increase the efficiency of the sprayer and its performance.

This goal is achieved by the fact that a disk sprayer containing a coaxially arranged upper disk and a bottom sprayer that is simulated to the drive shaft.

Claims (2)

Id a disk with a blade on the eho of the working split XHOCtH and a pointed spray edge, protruding on the edge of the upper disk, which covers the spray pattern drying the sprayed IS product and a supply source of heat transfer fluid connected to it, and a frame of a product, and a piece of an extractor; the sprayed product is made in the form of placed along the flat surface of the flame of the spray M communicating with the supply source of the coolant of the chambers, the internal surface of which is about retracted to the plane of the spray pattern, vyp.polnen perforated. and externally located in the annular collection of the product. FIG. 1 shows a longitudinal section of the sprayer; in fig. 2 - unit for drying the sprayed product. The disc sprayer contains coaxially arranged upper disc 1 and mounted on the drive shaft 2 lower spray disc 3 with blades 4 on its working surface and with a pointed spray edge 5 protruding beyond the edge of the upper disc i concentrically covering the spray disc 3 drying unit b of the sprayed product associated with it is the coolant supply source 7. In addition, the sprayer is equipped with an annular collector 8 of the product with a tangentially installed discharge nozzle 9, and the drying unit b is designed as located on both sides of the plane of the spray pattern and communicating with the source 7 of the coolant supply chambers 10, , perforated, and the outer 12 is located in the annular collector 8 of the product. The suspension is supplied through the pipe 13. The disk sprayer works as follows. The yeast suspension flows through pipe 13 between the upper disk 1 and the lower spray disk 3 rotated on the drive shaft 2, where the blades 4 are pumped over the edge of the upper disk G onto the pointed spray edge 5 of the spray disk 3. Dispersed yeast enters the product bowl, where the radial movement of particles slows down they are dried in a suspended state HHW A jet of gas flowing out of the holes of the perforated surfaces of 11 chambers 10. The product through the outer surface 12 of chambers 10 enters into The face collector 8, from where it is discharged through the tangential nozzle 9. Such an embodiment of the sprayer allows reducing the drying volume and is limited to the volume located along both sides of the spray pattern. The perforated surfaces prevent the product from moving up and down from the plane of the spray pattern; and the gas streams flowing from the holes of the perforated surfaces contribute to the deceleration of particles and a decrease in the diameter of the spray pattern, as well as sticking of the product to the thermo-jet surfaces. Placing the outer part of the chambers in the annular collection helps to reduce the radial velocity of the particles, due to the expansion of the cross section in the region of the annular collection. Taken together, it increases the efficiency of the sprayer. The sprayer has a simple design, high reliability in operation, low cost, low metal and energy consumption and allows to obtain a commercial product directly at the outlet of the sprayer. Small dimensions ensure correspondingly low heat consumption for drying, require small areas and volumes of production premises, and can be used to service personnel with low qualifications with full automation of the process. The invention includes a disc sprayer containing a coaxially arranged upper disc and a lower spray disc mounted on a drive shaft with blades on its working surface and with an acute spray edge protruding beyond the edge of the upper disc concentrically concentrating the spray disc of the sprayed product and its source of supply with it. coolant, characterized in that, in order to improve the efficiency of the sprayer and its performance, it is equipped with an annular collection of a duct with a tangentially installed discharge nozzle, and a unit for drying the sprayed product made in the form of chambers placed on both sides of the plane of the spray and communicating with the coolant supply source of the chambers, the inner surface of which is facing the plane of the spray pattern is perforated and outer .
