Environment-cleaning dust-free table type cutting machine

Abstract

The invention belongs to the technical field of cutting equipment, and particularly relates to an environment-cleaning dust-free table type cutting machine. The environment-cleaning dust-free table type cutting machine comprises a shell and a cutting workbench arranged on the shell, wherein a saw opening is formed in the cutting workbench; an air suction bin is arranged below the cutting workbench; the saw opening serves as an air inlet of the air suction bin; an air outlet of the air suction bin is formed in the air suction bin; a horizontal centrifugal separator is installed at the air outlet of the air suction bin; a separator ash falling port is formed in the rear end of the horizontal centrifugal separator; a first ash collecting box is arranged at the separator ash falling port; a separator air outlet is formed in the front end of the horizontal centrifugal separator; a filter cylinder is arranged at the separator air outlet; and a negative pressure fan is installed at an air outlet of the filter cylinder. According to the environment-cleaning dust-free table type cutting machine, the dust-gas pre-separation of dust-containing airflow can be realized, not only can the dust-free cutting be realized, but also the long-term stable operation of the cutting machine can be guaranteed, and the environment-cleaning dust-free table type cutting machine is small in size and convenient to carry and use.

Description

technical field [0001] The invention belongs to the technical field of cutting equipment, and in particular relates to an environmentally clean dust-free desktop cutting machine. Background technique [0002] In production and life, it is necessary to use a desktop cutting machine to cut wood, stone, tiles and other materials. These materials will generate a lot of dust during the cutting process, which will endanger the health of the operators and also have an adverse impact on the surrounding environment. For this reason, countries around the world have strict requirements on these dust emissions. The EU standard prEN16770 stipulates that the dust emission requirements for wood cutting should be less than 100μg / m 3 , the United States Occupational Safety and Health Administration (OSHA) stipulated in OSHA 3902-10 2016 that the dust emission requirement for stone cutting should be less than 50 μg / m 3 , The dust collection rate is greater than 99%. [0003] The main techn...

Problems solved by technology

[0004] This technical solution has the following disadvantages: (1) it can effectively suppress dust in the initial stage, but as a large amount of dust is collected, the clogging of the filter bag will gradually increase, resulting in a rapid decline in the dust collection capacity; (2) the cleaning of the filter bag is difficult and easy Cause secondary pollution; (3) The filtration efficiency of the dust filter bag is not high, and a large amount of small-diameter dust is still discharged into the atmosphere, which cannot meet the dust emission requirement of less than 50 μg / m 3 , if it is necessary to meet the requirements of this standard, HEPA (HEPA) must be used for filtration, but a large amount of dust generated during the cutting process will rapidly cause the HEPA filter to block and thus cannot operate normally; (4) Since the cutting machine needs to be frequently transported to the work site To carry out work, it is required that the volume of the cutting machine should not be too large

[0005] Based on the above reasons, the current desktop cutting machine cannot meet the requirements of the dust emission standard in the environment and ensure the long-term stable operation of the equipment and the problem that the volume should not be too large. How to overcome the above problems has been a long-standing technical problem in the industry
