Discharging pot for powder and particle materials

Abstract

The invention relates to a discharging pot for powder and particle materials. The discharging pot comprises a pot body and a discharging tube, wherein a plurality of vent tubes are longitudinally arranged at the bottom of the inner wall of the pot body, a plurality of air outlets are formed in the vent tubes, and air inlets communicated with the vent tubes are formed in the pot body; fluidization cloth is also fixed at the periphery of the lower part of the inner wall of the pot body, the periphery of the fluidization cloth and the periphery of the inner wall of the pot body are sealed, the center of the fluidization cloth is fixed to the center of the bottom of the pot body, a vent region is formed in the central part of the fluidization cloth, and the vent tubes are positioned between the inner wall of the pot body and the fluidization cloth; a feed opening of the discharging tube is positioned 1-50cm above the vent region. According to the discharging pot disclosed by the invention, the original structures of a material sliding board and the like which are in the traditional discharging pot body are eliminated and are changed into a fluidization structure formed by cloth and multiple vent tubes. The discharging pot has the advantages that the cost is low, the structure is simple, the manufacturing and the mounting are easy, the maintenance is convenient, the discharging is convenient and rapid, and the used space is large.

Description

technical field [0001] The invention relates to a discharge tank for powder materials. Background technique [0002] In recent years, due to the country's increased efforts in economic construction and the rapid development of infrastructure, roads, bridges and housing construction, cement, mineral powder, lime powder, mortar, metal powder, rice, corn and other civil and industrial powders The production and sales of granular material media are growing rapidly. Tank trucks, fixed tanks, storage containers, etc. have become the mainstream means of transportation for powder materials due to their advantages of environmental protection, economy, and high efficiency. Tank trucks are suitable for bulk transportation of fly ash, cement, lime powder, ore powder, granular alkali and other powdery dry materials, which can save a lot of packaging resources and loading and unloading labor for the country. [0003] The structure of the existing powder material unloading tank is relati...

AI Technical Summary

Problems solved by technology

[0004] (1) The production workload is heavy. Due to the complex structure of the tank truck, it takes a lot of time to manufacture and install, and the installation process is complicated. A defect in one of the steps will cause quality problems, increasing the difficulty of after-sales service and cost;

[0005] (2) Due to the complexity of the internal structure of the tank and the inability to solve the problem of welding gravity of the steel plate and welding in place, many steel plates will crack from time to time, which will make product maintenance troublesome and also cause inconvenience to unloading. One of the small Small slippery boards or fluidized bed boards are cracked, and sometimes it is necessary to manually unload the entire truckload of cement from the feed port;

[0006] (3) The production of sliding plates, fluidized beds, high-pressure gas chambers, and balance pipes requires at least 2 tons of steel, and manual welding between components is required, which greatly increases the cost;

[0007] (4) The production is difficult, the design requirements are high, and the angle between the sliding material plate and the fluidized bed is high. For example, an angle is required for cement loading, an angle is required for lime material, and an angle is required for mineral powder, etc. Unloading will be incomplete and a large amount of residual material will be generated; and because the tank body is different in size and different user requirements are not the same, the technicians must check the angle and thickness of each sliding plate, fluidized bed, and air chamber plate. The size is adjusted, which greatly increases the workload;

[0008] (5) The sliding plate, fluidized bed plate, high-pressure air chamber, balance air pipe, etc. occupy a certain space, which reduces the use space of the transportation medium to a certain extent, and the increase of compressed air due to the increase of space increases the Increase the speed time of the engine to the air compressor, increase the cost, and increase the exhaust emission
