Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a multi-angle mechanical dust removal arm. Background Technology
[0002] In today's industrial production and sample preparation fields, the sample preparation process is a crucial part of the entire production process, and the standardization and scientific nature of its operation directly affect the quality and efficiency of subsequent production. However, in the actual sample preparation process, there is a prominent problem that urgently needs to be solved—dust pollution.
[0003] Once the sample enters the sample preparation process, it undergoes several key steps, including crushing, mixing, and reduction. During the crushing stage, strong external forces gradually break the sample into smaller particles, inevitably generating a large amount of fine dust. When reducing the sample size, the turning and cutting of the sample causes these fine particles, originally attached to the sample surface, to detach and disperse into the surrounding air.
[0004] The dust generated during sample preparation poses multifaceted hazards. From an environmental perspective, it severely pollutes the air. The air quality in what was once a clean production workshop deteriorates drastically due to the presence of this dust. Long-term work in such an environment leads to the gradual accumulation of dust on equipment surfaces, floors, and in every corner, making the entire production environment dirty and unsanitary. From a human health perspective, dust is a highly hazardous pollutant. When workers inhale air containing large amounts of dust, the dust particles enter the respiratory tract, adhering to the mucous membranes of the trachea, bronchi, and even lungs, causing symptoms such as coughing, wheezing, and difficulty breathing. Prolonged exposure to high concentrations of dust can also lead to serious occupational diseases such as pneumoconiosis, severely threatening workers' health and lives.
[0005] Meanwhile, dust accumulation also significantly impacts the normal operation of production equipment. Large amounts of dust enter the equipment's interior, adhering to the surfaces of mechanical parts, increasing friction between components, and leading to accelerated wear. For example, dust accumulation on some transmission components can reduce transmission efficiency or even cause parts to seize up. In electrical equipment, dust can also cause short circuits and other malfunctions, affecting normal operation. These problems not only degrade equipment performance but also frequently trigger equipment failures, thereby reducing production efficiency and preventing production from proceeding as planned.
[0006] To address dust pollution, many organizations have equipped themselves with dust collection equipment. However, existing dust collection equipment has several limitations. Firstly, some equipment is inefficient, failing to effectively capture and collect all dust particles, resulting in a large amount of dust still being released into the air, thus failing to fundamentally solve the dust pollution problem. Secondly, some dust collection equipment consumes significant amounts of energy during operation, increasing production costs. Furthermore, the maintenance and upkeep of dust collection equipment are complex, requiring specialized technicians, which also places a burden on businesses. Summary of the Invention
