Automatic particulate matter unloading railway hopper car

Abstract

The invention discloses an automatic particulate matter unloading railway hopper car which is composed of a car body, a braking device, a car coupler buffering device and a bogie. The hopper car adopts an unloading mode of loading from top to unloading from bottom, the whole car is provided with six through loading and unloading cargo holds, the corresponding car roof is provided with six loading ports, and the bottom is provided with six hoppers and an unloading device. A hopper car body is composed of a car roof, end walls, side walls, partition walls, a bottom frame, a hopper, an unloading device and the like, the bottom frame, the side walls, the end walls and the car roof integrally form a box-shaped structure, the side walls are of arc wrapper sheet structures, the hopper is arranged on the lower portions of the side walls, and the partition walls are arranged between the two side walls and are in rigid connection with the side walls and the bottom frame correspondingly, so that the overall strength and rigidity of the car are improved; the vehicle body has the characteristics of light dead weight and large load capacity; due to the top-loading and bottom-unloading unloading mode, a plurality of loading and unloading cargo holds can work at the same time, and the loading efficiency is improved; gravity and pressure air are mixed for unloading, the unloading speed and capacity of the vehicle can be improved through the annular pressurizer, and blockage is prevented.

Description

technical field [0001] The invention belongs to the technical field of railway transportation equipment, and in particular relates to a particulate matter-carrying railway hopper car with an automatic unloading function for unloading by utilizing the mixed action of gravity and air. 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. 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 fi...

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
