Water conveying device of granular material pipeline

Abstract

The invention relates to a water conveying device of a granular material pipeline. The water conveying device comprises a material conveying pipe, a water supply pipe, a water spray pipe, a main water pump and a feed hopper, wherein a nozzle is arranged on the front end of the water spray pipe, the front end of the nozzle extends into the back end of the material conveying pipe, the front end of the water spray pipe is fixed to and is in sealing connection with the back end of the material conveying pipe, the back end of the water spray pipe is connected with a water outlet of the main water pump, the lower end of the feed hopper is connected with the top of the material conveying pipe, a feed opening is formed in the bottom of the feed hopper and is located above the nozzle, a water spray opening in the front end of the nozzle is located in the front side of the feed opening in the bottom of the feed hopper, the nozzle is of a conical structure of which the front part is thin and the back part is thick, the outside diameter of the back end of the nozzle is equal to the inside diameter of the material conveying pipe, one end of the water supply pipe is connected to the water spray pipe, the other end of the water supply pipe is connected to the upper part of the feed hopper, and a regulating valve is arranged on the water supply pipe. The water conveying device has the advantages of reasonable design, easiness in operation, high degree of automation, high controllability, high conveying efficiency, difficulty in blocking, high practicability and easiness in popularization and application, and the abrasion influence of solid particles on the main water pump and an enhanced water pump is avoided.

Description

technical field [0001] The invention belongs to the technical field of hydraulic transportation, and in particular relates to a pipeline hydraulic transportation device for granular materials. Background technique [0002] At present, pipeline hydraulic transportation is only in the research stage. Hydraulic transportation requires high concentration and low energy consumption. Generally, straight-through pipelines often require high flow rates to transport high-concentration materials, resulting in high energy consumption; the addition of granular materials in continuous work also affects One of the main reasons for work efficiency. In addition, long-distance pipeline hydraulic transportation will also cause a certain degree of blockage due to the gradual decrease of water pressure. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a pipeline hydraulic conveying device for granular materials with high c...
