Abstract

The invention relates to teak classification of granular materials into fractions and reduces the energy consumption of the installation when separating watered sand and gravel mixtures by providing a vibration effect on sieve 2 by using the energy of the mixture flow, i.e. without power consumption. A screen 2 is rigidly connected to the vibration exciter (B) 7. Impeller 6 is installed below the screen 2, kinematically connected to B. 7. Under screen 2 above the impeller 6, a profile breaker sheet 10 is mounted. The screen 2 is mounted on springs 9 and in the upper its part is fixed pivotally. The unloading fixture of the installation is made in the form of a bunker for removal of the podite product and an ejector hydrotransport device installed in the lower part of the bunker. The raw material from the loading device is fed to a sieve 2, where it is divided by size. The podite product together with water enters the fender sheet U, from where it rolls onto the impeller 6, ensuring the operation of B 7. From the bunker, the lodsite product enters the hydrotransport device and enters the warehouse via the drain pipeline. 1 hp f-ly, 2 ill. i (L; / с SL O5 with so fi.2

Description

one

The invention relates to a technique for classifying granular materials into fractions and can be used in the industrial construction of nonmetallic building materials for separating forest gravel mixtures into sand and gravel.

The purpose of the invention is to reduce the energy intensity of the installation when separating watered sand-gravel mixtures by providing a vibration effect on the sieve by using the energy of the mixture flow, i.e. without power consumption.

FIG. 1 shows the installation, general view; in fig. 2 is a section A-A in FIG. one.

The plant for separating granular materials contains a loading device 1 mounted above the fixed-stern in the upper part of the sieve 2, under which the discharge device is dispensed in the form of a bunker 3 for removing the added product and the ejector hydrotransport device 4 installed in the lower part of the bunker 3 coaxially with the drain pipe 5. Under the sieve 2, the impeller 6, is kinematically connected to the vibration exciter 7, mounted on the platform 8, which is rigidly connected to the lower end A sieve 2. A platform 8 with a sieve 2 is mounted on springs 9. Above the impeller 6, a profile baffle plate 10 is attached to the inner wall of the hopper 3, which directs the flow of sub-material (slurry) to the impeller 6. To prevent chaotic flow of residual slurry onto the impeller the impeller 6 above it on the platform fixed casing 11.

The installation works as follows.

The starting material (slurry) is fed from the loading device 1 to sieve 2, where it is

separation according to size, corresponding to the screen gap. Particles smaller than the screen slot pass along with the water through the latter and fall onto the baffle plate 10, from where they roll onto the impeller 6 of the vibration exciter 7, ensuring its operation. Next podsitovy product from the hopper 3 enters the hydrotransport device 4 and through the pipeline 5 drain enters the warehouse or further processing. The operation of the vibration exciter 7, which is rigidly connected to the spring-loaded sieve 2, ensures its continuous oscillations and, therefore, cleaning of impurities and particles of the boundary size.
