SU1222316A1 - Installation for dehydration of seeds - Google Patents

Description

The invention relates to devices for separating water from a granular material after their separation by sintering and can be used in mineral processing, agriculture, and other areas of the national economy.

The purpose of the invention is to increase the degree of dewatering of the washed material due to the removal of separated water.

FIG. 1 shows the installation, general view; in fig. 2 — node 1 on .1 (gravitational outlet catchment basin); in fig. 3 - tray with gravity discharge headers, top view.

The installation consists of a sorting chamber 1 connected by pipelines 2 and 3 with vibrating channels 4 having a lattice bottom 5. Gravity discharge tanks 6 are installed across trays 4 at a distance of 15–30 cm. A collection container 7 is mounted under the trays.

The water collectors 6 consist of a clamping bar 8, two layers of sealing materiad 9 at the top and bottom of the bottom 5. Below the sealing material 9, a drainage system 10 is installed. The water collectors 6 are connected to the bottom plate with bolts i 1.

The installation works as follows.

Seeds sorted into fractions in the sorting chamber 1, through pipelines 2 and 3, are transported by liquid to the cracked bottom 5 of the oscillating trays 4. The free transporting liquid passes through the cracked bottom 5 and flows into it 3, 0 2.8 3.2

bone 7. The seeds, together with the fluid retained in the intercostal space, under the action of energetic vibrations of the trays 4 begin to move along the grate bottom 5 and are arranged in a thin layer (layer of one grain) across the entire width of the trays 4, and the moisture passes to the surface of the grate bottom 5 and flows down in the direction of inclination of the trays 4. Moisture flows down the upper and lower surfaces of the bottom sieve 5. Reaching the sealing material 9 of the gravity sewer 6, the moisture is delayed and transferred to the drainage 10, from where it is accumulated and under the action of gravitational forces and shaking trays 4, overcoming the forces of intermolecular adhesion, separates and enters the container 7. The presence of a narrow edge at the drainage system 10 facilitates the process of separating the accumulated moisture.

On installation with tray length

2.5 m and a width of 0.18 m with an oscillation amplitude of 30 mm, the water tanks are installed at a distance of 200 mm. Dehydrated are sorted wheat grain Mironovsk -BOS.

The table shows the performance and humidity of the known and the proposed installation at an oscillation frequency of 525 per minute.

The application of the present invention allows an increase in productivity by 55% with the same final moisture content of 3.3%.
