Description

one

The invention relates to the field of hydraulic transport.

Limes loading device for the hydraulic transport of raw materials, containing two chambers, each of which has a loading gate, pipelines for supplying transport water and draining pulp. The chambers are alternately loaded with bulk material and water is pumped into them under pressure, which washes out the material and, in the form of pulp, transports it through the pipeline to the place of discharge.

The disadvantage of this loading annarate is the need to drain out the wastewater when the chamber is loaded in a volume equal to the volume of material loaded into the chamber. Laminated water is reusable.

The aim of the invention is to eliminate the discharge of water when loading the chambers of the apparatus.

This is achieved by connecting a pipeline with a controllable valve to the top of each chamber for supplying compressed air to the chamber during unloading.

The drawing shows the proposed device.

It consists of q, woo cylindrical chambers 1 and 2 with coius bases. Each chamber is sabzhenna with a receiving funnel with a spherical loading gate 3. When loading

the bulk material into the chamber is irrigated with water to increase its mobility. The conical base chambers are connected to the branches of the pipeline 4 for supplying transport water under pressure, on which control valves 5 and 6 are installed. Discharge elbows 7 are connected to telescopic cone nozzles 8 by means of control back valves 10 and 11.

To the upper part of the chambers, a compressed air duct 12 is connected with a clavier 13 and 14.

The machine works as follows.

The drawing shows the state of the apparatus, at which chamber 1 is loaded and chamber 2 is unloaded. Bulk material is loaded into chamber 1, which has a spherical valve 3 at the same time. Water flows into the receiving funnel of the chamber The material in the chamber p magnifies its mobility. Water impregnates the material and n fills its entire interstitial space in such a way that, when the chamber is completely filled, a film of water hardly protrudes above the layer of material. At this point, the loading cycle of the camera ends and the spherical shutter 3 is closed. At the time of loading of the camera 1, the keys 5, 10 and 13 are closed. At the same time with

By loading chamber 1, chamber 2 is unloaded. Thus, pressure water enters chamber 2 through the open valve 6 through pipe 4, which captures particles of solid material that settle to the top of the concave base of the chamber and in the form of pulp through the discharge elbow 7 and the open non-return valve 11 directed to conduit 9 for pulp removal. Compressed air enters the upper cavity of chamber 2 through control valve 14 through conduit 12, which pushes thick pulp back to the washout site.

Entering compressed air into the apparatus chamber when it is unloaded allows the chamber to be completely cleaned of bulk material, to eliminate water discharge from the chambers and thereby increase the operating efficiency of the charging unit.
