Description

The invention relates to the pneumatic conveying of granular materials, mainly expanded clay gravel, and other materials with a density close to the density of water, and can be used in various industrial areas, such as construction.

The purpose of the invention is the expansion of technological capabilities by facilitating the washing and treatment of the bulk material with a liquid.

The drawing shows the device, the overall appearance.

The device comprises a frame 1 on which a hopper 2 is mounted, having in its upper part a guide cone

3, rigidly connected by its upper part to the transport pipeline

4, feeding the transported material to the work site. The hopper 2 is loaded with granulated material through a loading hatch, hermetically closed with a lid 5. The hopper 2 is filled with liquid through a pipe 6 supplying liquid with shut-off valves, and a drain through a similar pipe 7. Flow is supplied to the hopper 2 through the air supply pipe 8 compressed gas, at the end of which there is a check valve 9, which prevents the liquid from penetrating into this nozzle when it fills the hopper 2.

The device works as follows.

From the car (dump truck) into the hopper 2 is loaded granular material - expanded clay. The lid 5 is sealed (locks not shown). At the same time, claydite in the bunker 2 is located in a heap at the edge of the hatch of the bunker 2. The valve on the nozzle 6 opens and the liquid (water) fills the bunker 2 through it. The water level in the bunker 2 is controlled by an overflow pipe 10 with stop valves. Since the density of claydite is less than water, then a heap of it gradually, as it is filled with water, begins to float and concentrate in the guiding cone 3, partially filling the lower part of the pipeline A, i.e. before the nozzle 8 compressed gas supply. The air supply is turned on, and

The entire mass of haydite, which is located in front of which, with the nozzle of the nozzle 8, rushes upwards in order to expand the process flow along the pipeline 4 to the production site by ensuring the washing of works. After a portion of claydite is supplied, the air supply stops the processing of the bulk material with liquid, it is equipped with nozzles under 0

The curlmchit, which was hovering on the bunker 1, which was not captured by the first successful IKITOKOM, again fills the guide cone. and the lower part truboprpps) yes. The cycle is repeated until the end of the bunker 2 from the ceramics: it. After that, through the drain pipe 7, the water is drained, the cover 3 is opened, etc. Water can be discharged into any container, and from there the pump is pumped back to the hopper through nozzle 6. When the device operates, there is no excessive air loss, the speed of the air flow, the passage through the liquid increases. The efficiency of the device and its performance also increase. In addition, in the clay there are always defective materials: stones, dirt, etc. Filing them to the place of work on the roof, overlap, etc. not valid. When the hopper is filled with liquid, these inclusions, since they are tighter than haydite and water, precipitate into the sediment (are discarded) and are removed from it after emptying the bunker. In addition, intensive washing of the claydite with water enhances the quality of its subsequent installation, for example, laying of expanded clay as a heater for cement drainage. When a granular material is supplied with a density equal to the density of water, water solutions of various salts whose density is greater than pure water can be used as a liquid. The installation is easy to manufacture and operate, and simultaneously performs the culling, cleaning and wetting of granular materials.
