Powder material loading device with dynamic rapid discharging function

Abstract

The invention relates to a powder material loading device with a dynamic rapid discharging function. According to the technical scheme, the lower part of a body is provided with a breathable layer, the breathable layer divides the interior of the box body into an upper material bin and a lower inflation bin, the side wall of the box body in which the inflation bin is located is connected with an inflation pipeline communicating with an inner cavity thereof, the top of the box body in which the material bin is located is provided with a material opening communicating with the inside and the outside, a discharging pipeline with a sliding connection is arranged on the material opening in a penetrating manner, an annular air bag fixing edge is fixed to the top surface of the box body around the material opening, and an annular air bag used for pressing and fixing the discharging pipeline is arranged in the inner side of the annular air bag fixing edge. According to the device, flow of thepowder material is monitored in real time through a powder flow meter, the height position of the discharging pipeline is adjusted in real time according to the flow value, the lower opening of the discharging pipeline is always kept a closer distance to the top surface of the powder material, a space for releasing pressure and feeding is provided, high-speed unloading is always maintained, the discharging time is compressed, and the discharging cost is saved.

Description

technical field [0001] The invention relates to a powder material conveying device with a dynamic and fast discharging function. Background technique [0002] Most industrial powder materials have small particles, strong fluidity, easy to be lost, and easy to be polluted. At present, such powder materials are often transported by car or train. During transportation, the powder materials are usually packed into chemical fiber packaging bags and sealed Then put them into cars or train carriages. After arriving at the destination, take out the packaging bags, cut the packaging bags, and unload the powder materials. This mode of transportation has the following disadvantages: the packaging bags are scrapped after unloading, and the packaging bags can only be used once. The cost of the product is increased, and the waste is very serious. Because the materials must be cut and unloaded one by one, the loading and unloading efficiency is low; and it will cause the phenomenon of dust...

[0002] Most industrial powder materials have small particles, strong fluidity, easy to be lost, and easy to be polluted. At present, such powder materials are often transported by car or train. During transportation, the powder materials are usually packed into chemical fiber packaging bags and sealed Then put them into cars or train carriages. After arriving at the destination, take out the packaging bags, cut the packaging bags, and unload the powder materials. This mode of transportation has the following disadvantages: the packaging bags are scrapped after unloading, and the packaging bags can only be used once. The cost of the product is increased, and the waste is very serious. Because the materials must be cut and unloaded one by one, the loading and unloading efficiency is low; and it will cause the phenomenon of dust flying all over the sky, which is not good for the health of the loading and unloading workers, and also pollutes the environment. Therefore, the applicant first applied for The patent No. "201320338730.3" of the "air-bed powder material shipment device" and the patent number "201520066730.1" of the "bag type powder material shipment device" have solved the above problems to a certain extent, but whether the above patent application The technical scheme is still the existing iron compartment. When unloading, it is all conveyed by wind under the effect of wind pressure through the discharge channel stretching into the discharge port. Because of its structural problems, there are the following problems: 1. The top of the compartment The discharge port and the feed port are respectively set up, and the discharge pipeline is directly installed on the discharge port. In order to ensure complete discharge, the discharge pipeline must extend to the bottom of the powder material, which leads to the process of wind discharge. The compressed air needs to pass through the gap of the powder material before entering the discharge pipeline, and the pressure release speed is slow, resulting in slow discharge speed and low efficiency; 2. The discharge port extends into the bottom of the box body, and during the loading or transportation The powder material enters the discharge pipeline, which leads to the blockage of the discharge pipeline, and the pipeline needs to be cleaned before unloading, which further reduces the discharge efficiency; therefore, its improvement and innovation are imperative
