Abstract

The invention relates to pumps for grinding and pumping fluids with fiber and long stem inclusions. The pumped medium enters the housing 1 through a pipe 10 located on the front side of the housing and then, when the holes 15 and 13 coincide, passes into the diffuser inlet 14. The long stem inserts are crushed by the edges of the holes 13 and 15. That is, the medium enters the impeller 2 pre-crushed, which eliminates the clogging of interscapular channels of the wheel 2 and thereby increases the operational reliability of the pump. In the impeller 2, further grinding of the medium takes place due to the protrusions and depressions 6, 7 on the finned surface 5. 3 Il.

The invention relates to pump construction and is an improvement to your pump according to the author. NW, N ° 1332077.

The purpose of the invention is to increase the operational reliability and improve the grinding medium.

The pump for grinding and pumping inhomogeneous media comprises a housing 1 and an impeller 2 installed in it with blades 35 forming interscapular channels 4;

on the surfaces of the housing 1 and the blades 3 facing each other, the fins 5 are made of interacting concentric protrusions 6 and the response depressions 7, and the radial channels 8 are made on the silver surface of the housing 1. The impeller is equipped with a driving disk 9, blades 3 located on the latter, the fins are made at a depth equal to the width of the blade and the radial channels 8 are the profile that matches the profile of the interscapular channels 4. The pump is equipped with a supply nozzle 10 located on the front side 11 of the housing 1, and on the opposite side oh its side 12 coaxially pipe 10 has an opening 13 communicating with the inlet 14 of the pump, while on the finned surface of the wheel provided with a through hole 15 at the radius position races inlet pipe 10 and inlet 14 of the pump diffuser adapted. The pump works as follows. The mass to be processed under pressure enters the nozzle 10 to the openings 13 and 15 at the moment of their coincidence, where due to the interaction of the edges of the openings of the rotating wheel 2 and the edges of the openings of the housing 1, the long-stemming inclusions are crushed and then fed to the diffuser inlet 14. Under the action centrifugal forces of the rotating impeller

They are thrown onto the walls of the diffuser inlet 14 and enter the interscapular channels 4 at the time of their coincidence with the similar radial channels 8 of the housing 1.

When the medium moves through the channels 4, as a result of their opening and closing with a frequency of 100–200 Hz and impacts of inclusions on the end surfaces of the projections 6 and depressions 7, impulses of hydrodynamic pressure appear. When this occurs, the conversion of kinetic energy into pressure and vice versa. As a result of the alternation of these processes, the shells of elastic inclusions break up both across and along the fibers, thanks to which they acquire a fluffy well-developed (activated) surface. More durable inclusions are subjected to repeated action of protrusions 6 and depressions 7. Under the action of centrifugal forces and pressure pulsations, the treated medium is forced out to the pump outlet. The provision of a pump nozzle allows pre-crushing of long-stem-bearing inclusions, as a result, they prevent clogging of interscapular ducts 4, thereby increasing operational reliability. Performing an inlet 14 with a diffuser allows directional feeding. medium to interscapular: i radial

channels 4 and 8.
