Embodiment Construction
[0015] Below in conjunction with accompanying drawing, the present invention will be further described.
[0016] Such as figure 1 Shown is a schematic diagram of the frequency conversion unloading system of the present invention. The frequency conversion unloading system includes a main frequency conversion unloading valve, a pipeline pressure relief device, and an exhaust and dust removal device. The main frequency conversion unloading valve includes a main valve body and a main frequency conversion motor 110 that drives the star-shaped parts inside the main valve body to run. Both the main valve body and the main frequency conversion motor can be selected from existing products, or specially designed solutions can be selected according to needs. The inlet of the main valve body is in airtight communication with the feed pipeline, and the outlet of the main valve body is in airtight communication with the feed end 211 of the pressure relief pipe section. The pipeline pressu...

The invention relates to a frequency conversion unloading system, which includes a main frequency conversion unloading valve, a pipeline pressure relief device and an exhaust and dust removal device. The main variable frequency motor and the pipeline pressure relief device include a pressure relief pipe section and a pressure relief guide plate arranged in the pressure relief pipe section. The pressure relief guide plate divides the inside of the pressure relief pipe section into a feed chamber and a pressure relief chamber. The pressure relief chamber A pressure relief exhaust pipe is provided on the side wall. The exhaust dust removal device includes a connecting pipe, a dust collection pipe and a dust collection box. An exhaust dust filter device is arranged in the dust collection box. The exhaust dust filter device includes a dust filter exhaust pipe, and the dust filter exhaust pipe is airtightly connected with the screen structure. The frequency conversion unloading system of the present invention adopts the combination of the frequency conversion unloading valve and the pressure relief pipeline from the two aspects of adjusting the flow rate of the material delivery pipeline and reducing the downstream air pressure of the material delivery pipeline. The problem of downstream blockage of the pipeline is solved, and the structure is simple and reliable.
Description
technical field [0001] The invention relates to a material conveying pipeline, in particular to a material conveying system using a frequency conversion unloading valve, and belongs to the field of pipeline transportation equipment. Background technique [0002] The pipeline transportation method is widely used in the field of powder and small material transportation. The pipeline transportation method using the unloading valve as the core component is widely used in environmental protection, metallurgy, chemical industry, grain, food and other industrial fields. This method usually relies on the pipeline The pressure gas inside pushes the material to be transported. The unloading valve usually uses the built-in star wheel parts to realize the continuous supply of materials, so it has the characteristics of small size, light weight, low noise, few failures, long life and reliable and stable operation. Commonly used discharge valves are basically quantitative discharge, and ...
