Accumulated water removing device for pneumatic material conveying system

Abstract

The invention discloses an accumulated water removing device for a pneumatic material conveying system. The accumulated water removing device comprises a moving body capable of achieving pneumatic conveying in a pneumatic conveying pipeline, the moving body is provided with an adsorption body made of a water absorption material, and the adsorption body makes contact with the inner wall of the pneumatic conveying pipeline to be used for adsorbing water on the inner wall when the moving body achieves conveying. The accumulated water removing device for the pneumatic material conveying system hasthe advantages that the water in the pneumatic conveying pipeline can be collected in time, the interior of the pneumatic conveying pipeline can be kept dry and clean, and maintenance is easy.

Description

technical field [0001] The invention mainly relates to the field of material sample collection and processing equipment, in particular to a water accumulation cleaning device used in a material pneumatic transmission system. Background technique [0002] For the sampling, sample preparation, and testing of material (such as ore, coal) samples, each country has mandatory standards, and the sampling and processing of samples must be carried out in accordance with the standards. The principle of sample sampling, sample preparation, and testing work process is to gradually reduce the particle size and quality of the collected samples without destroying the representativeness of the sample, until it meets the particle size and quality of the sample in the laboratory test ( Weight) accuracy requirements, and then carry out relevant laboratory analysis on the samples that meet the requirements. [0003] For example, taking coal sampling as an example, it is actually a sampling and...

Problems solved by technology

[0005] (1) In actual work, due to temperature changes, air compression and other reasons, condensed water will appear on the inner wall of the pneumatic transmission pipe

In addition, the transmission pipeline is not tightly closed, and rainwater leakage and sample bottles may cause water accumulation inside the transmission pipeline.

The stagnant water will generally accumulate in the pipeline, or even block the pipeline, which not only affects the transmission of the sample bottle, but also may cause the stagnant water to penetrate into the sample bottle and contaminate the sample.

[0006] (2) Difficult to clean and maintain

However, the accumulated water buffer device needs to be manually opened and released regularly, which poses a safety risk for high-altitude operations, and is time-consuming and labor-intensive, making it difficult to maintain

Second, the cold weather will cause the accumulated water to freeze in the buffer device, making it impossible to open the gate to release the water

If the accumulated water cannot be cleaned in time, it will overflow into the pipeline or even freeze in the pipeline, which will seriously affect the work of pneumatic transmission
