Particulate matter unloading device special for railway hopper car

Abstract

The invention discloses a particulate matter unloading device special for a railroad hopper car, which is arranged at the bottom of each separated cargo storage cabin of the railroad hopper car, and comprises two sets of unloading mechanisms which are arranged at the bottom of each group of cargo storage cabin and are symmetrically arranged along the two sides of a car body, and air is supplied to the two sets of unloading mechanisms in parallel by an air supply system connected with an air compression mechanism; each unloading mechanism comprises an unloading funnel, an unloading mixer and an annular pressurizer. The gravity and pressure air mixed unloading technology is adopted, and the unloading speed and the unloading capacity of the vehicle are improved through the specific function of the annular pressurizer; an unloading mixer flows into a mixing tank under the gravity action of particulate matters, meanwhile, pressure air enters the mixing tank from a porous plate to form a gas-solid two-phase mixture with the particulate matters, so that cargoes have certain flowability and flow out from a straight-through pipe of an annular pressurizer, and meanwhile, the unloading efficiency is improved under the assistance of negative pressure generated by the annular pressurizer; the bottoms of all the bins of the tank truck are symmetrically arranged to achieve simultaneous unloading on the two sides of the truck body, and the unloading capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of railway transportation equipment, and particularly relates to a particulate matter unloading device for a special railway hopper car. Background technique [0002] With the growth of the national economy, the demand for synthetic resins is also increasing. Synthetic resin raw materials are granular and flowable solid materials, and railway transportation is beneficial to reduce the cost of goods and improve transportation efficiency. [0003] At present, domestic and foreign synthetic resins are mainly transported by railway boxcars, containers and special road tankers. The railway boxcars are mainly shipped in 25kg woven bags, which have the following problems: high packaging cost, high transportation loss, many times during transportation, and easy damage; and its loading and unloading labor costs are high, requiring at least five links from the petrochemical enterprise to the client. Manual handling ...

AI Technical Summary

Problems solved by technology

Railway boxcars are mainly shipped in 25kg woven bags, which have the following problems: high packaging cost, high transportation loss, repeated overturning during transportation, and easy damage; and high labor costs for loading and unloading, requiring at least five links from the petrochemical enterprise to the client Manual handling or loading and unloading

In recent years, some domestic enterprises have begun to use road tankers for customers in the region. This mode of transportation is not suitable for long-distance and large-volume transportation, and road transportation is greatly affected by uncontrollable factors such as weather and road conditions.

Highway special tank vehicles have a small load, and the cost of a single vehicle is high, and the overall transportation cost is relatively high
