Tank type powder material carrier vehicle and discharging device thereof

Abstract

The invention discloses a discharging device of a tank type powder material carrier vehicle, which comprises an air compressor (7). An air outlet of the air compressor (7) is communicated with an air inlet of an air chamber of a tank body (22) of the tank type powder material carrier vehicle, and a discharging port of the tank body (22) is communicated with a storage tank. The discharging device of the tank type powder material carrier vehicle further comprises a first pressure detection device (23) detecting internal pressure of the tank body (22) and a second pressure detection device (1) detecting pressure of an air inlet pipeline. The first pressure detection device (23) is installed inside the tank body (22), and the second pressure detection device (1) is installed on the air inlet pipeline. Accordingly, pressure in an air inlet pipe and pressure difference between the inside of the pipe and the inside of the tank body can be detected conveniently, a pressure state of the inside of the pipeline can be detected in real time, and potential safety hazards are avoided. The invention further provides the tank type powder material carrier vehicle comprising the discharging device.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an unloading device for a tank-type powder transport vehicle. The present invention also relates to a tank-type powder transport vehicle comprising the above-mentioned unloading device. Background technique [0002] With the rapid development of my country's economic construction, the market demand for construction machinery, especially tank-type powder transport vehicles, is increasing. The tank-type powder transport vehicle is a kind of construction transport machinery used for transporting ready-mixed dry-mixed mortar, cement, ore powder and other powder materials. [0003] Tank-type powder transport vehicles mainly have three types: horizontal, vertical, and lifting. The unloading device of the tank-type powder transport vehicle includes an air compressor and an air chamber installed in the storage tank. A fluidization device, the fluidization device is used to fluidize...

AI Technical Summary

Problems solved by technology

[0005] The gas compressed by the air compressor comes from the atmosphere, and there is a certain amount of moisture in the air, especially under the conditions of rainy or humid air. The moist air is compressed by the air compressor and used to transport dry-mixed mortar materials, resulting in The fluidization device has serious sticky material, material hardening, and frequent material blockage in the discharge pipe, which seriously affects the continuity of unloading, unloading speed, mortar quality and transportation efficiency;

[0006] The gas compressed by the air compressor is a pulsed air flow, which has a large impact on the gas pipeline device and a large vibration, which leads to the easy loosening of the bolt connection of the pipeline structure, and even causes fatigue and cracking of the local weld seam, which affects its safety. In addition, the vibration Larger results in segregation of dry-mixed mortar;

[0007] The pressure in the intake pipe is unknown, the pressure difference between the pipe and the tank cannot be obtained, and the opening degree of the blowing aid valve cannot be judged. If the pipe is blocked, the pressure of the pipe cannot be detected, which poses a safety hazard;

[0008] The pipelines in the gas system are mainly steel pipes, and the pipeline structure is complex. When the pipes are connected, it is difficult to accurately locate and install, and the assembly efficiency is low.
