Powder material transport vehicle and its storage tank

Abstract

The invention discloses a powder and particle material transport cart and a material storage tank thereof. The material storage tank comprises a tank body, a material cover arranged on the tank body and an exhaust device. The exhaust device comprises an exhaust valve located on the outer portion of the tank body and a connection pipe. The air outlet end of the connection pipe is connected with the air inlet end of the exhaust valve in a sealing mode. The air inlet end stretches into the tank body and is communicated with the inner portion of the tank body, and filtering cloth fixedly covers the air inlet of the connection pipe. Due to the fact that the filtering cloth covers the air inlet position fixedly, namely the filtering cloth covers the air inlet of the connection pipe, during air discharging of the tank body, air in the tank body is filtered by the filtering cloth when entering the connection pipe, residual powder and particle materials in the tank body are retained in the tank body due to filtering of the filtering cloth and cannot enter the exhaust valve through the connection pipe, blocking caused by the fact that the powder particles enter the exhaust valve is further avoided, and normal work of the powder and particle material transport cart is ensured.

Description

technical field [0001] The invention relates to the technical field of transportation, more specifically, to a powder material transport vehicle and a storage tank thereof. Background technique [0002] The powder material transport vehicle is a vehicle for transporting powder materials, which includes a tank body for holding powder materials, and the tank body is provided with a material inlet cover, a material outlet and an exhaust valve. Powder material transport trucks generally unload by pressure feeding, that is, pressurize the tank to discharge the powder material. After unloading, the pressure in the tank is often greater than atmospheric pressure. If the feeding cover is opened directly, the tank will be damaged. The residual material in the body is sprayed out to form dust pollution. Therefore, after the unloading is completed, the tank body must be unloaded. In the prior art, the tank body is generally unloaded through the exhaust valve. At the same time, in orde...

AI Technical Summary

Problems solved by technology

Powder material transport trucks generally unload by pressure feeding, that is, pressurize the tank to discharge the powder material. After unloading, the pressure in the tank is often greater than atmospheric pressure. If the feeding cover is opened directly, the tank will be damaged. The residual material in the body is sprayed out to form dust pollution

Therefore, after the unloading is completed, the tank body must be unloaded. In the prior art, the tank body is generally unloaded through the exhaust valve. At the same time, in order to avoid dust from polluting the environment, a dustproof bag is also connected to the outlet end of the exhaust valve. However, the exhaust valve is easily blocked after working for a long time in this way, and maintenance is difficult, which in turn affects the normal operation of the powder material transport vehicle
