Lower discharging device of powder and particle material transport vehicle

Abstract

The invention provides a lower discharging device of a powder and particle material transport vehicle and belongs to the technical field of manufacturing of powder and particle material transport vehicles. The lower discharging device structurally comprises a reducing elbow arranged on a tank body; the reducing elbow is arc-shaped; the diameter of one end of the reducing elbow is relatively small;the diameter of the other end of the reducing elbow is relatively large; the large-diameter of the reducing elbow communicates with the bottom of the tank body; the small-diameter end of the reducingelbow communicates with the feeding end of a connecting material pipe through a flange; the discharging end of the connecting material pipe is connected with a quick coupling or a discharging hose through a discharging butterfly valve; a material boosting device is arranged on the connecting material pipe; and a gas collection dustproof device is arranged right above the joint of the reducing elbow and the tank body in the tank body. The lower discharging device has the advantages of reasonable design, simple structure, small size, smooth discharging, convenience in use and the like.

Description

technical field [0001] The invention relates to a powder material transport vehicle, in particular to a bottom discharge device of the powder material transport vehicle. Background technique [0002] There are usually two ways of unloading powder material transport vehicles, namely upper discharge and lower discharge. Compared with the upper discharge method, the bottom discharge method has the advantages of simple structure, short required discharge pipe length, relatively smooth discharge, etc., but the bottom discharge structure of the prior art also has certain disadvantages: the bottom Not only is the size of the material port too large, but also the discharge port and the flange have a discharge dead angle, which leads to material retention and unsmooth discharge. At the same time, when the tank is filled with materials, the material will settle and accumulate at the discharge port, which cannot be achieved without a booster. work, so the lower discharge structure of ...

Problems solved by technology

Compared with the upper discharge method, the bottom discharge method has the advantages of simple structure, short required discharge pipe length, relatively smooth discharge, etc., but the bottom discharge structure of the prior art also has certain disadvantages: the bottom Not only is the size of the material port too large, but also the discharge port and the flange have a discharge dead angle, which leads to material retention and unsmooth discharge. At the same time, when the tank is filled with materials, the material will settle and accumulate at the discharge port, which cannot be achieved without a booster. Therefore, the lower discharge structure of the existing structure is usually equipped with more than two boosters, which is heavy, and the structure is not simple enough, inconvenient to use, and labor-intensive.
