Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of melon seed dust removal, and relates to a dust removal scheme, in particular to an air dust removal device, which can remove melon seed particles, smoke dust and other impurities in the generated gas during the roasting process of melon seeds to meet the requirement of purifying air. BACKGROUND

[0002] The roasting melon seed machine smoke dust removal device is a technical device for removing dust and impurities during the roasting process of melon seeds. In the traditional roasting process of melon seeds, a certain amount of dust and impurities are generated due to the shell of melon seeds, which not only affects the taste and quality of melon seeds, but also poses a potential risk to the health of operators.

[0003] To solve the dust removal problem in the roasting process of melon seeds, a melon seed automatic roasting device for small workshops is disclosed in Chinese Patent No. CN110476624A, authorized on November 22, 2019, which contains a dust removal part. The dust removal part drives the air suction fan to rotate while roasting melon seeds, blows the dust-containing gas to the dust collection box for filtration through the filter screen, so as to collect the dust on the melon seeds. This device is simple and convenient for handling larger particles of dust, but cannot handle small particles of dust.

[0004] Chinese Utility Model Patent No. CN207969635U, authorized on October 16, 2018, discloses a hot cycle roasting melon seed device, which uses a dry dust collector for dust removal. The structure is simple, but the dry dust collector is not ideal for removing small particles of smoke dust.

[0005] Chinese Patent No. CN111567831A, authorized on August 25, 2020, discloses a multifunctional roasting machine, which is mainly used to solve the problems of slow peeling of melon seeds and inconvenient dust removal. A cyclone dust removal device is used to filter the smoke generated during the roasting of melon seeds. However, it is also a dry dust collector, and the removal effect of small particles is still not ideal.

[0006] There is a lack of independent dust removal device for roasting melon seed machine in the market at present. The existing dust removal schemes mostly use bag dust collectors and wet dust collectors. The bag dust collector has the characteristics of simple structure and large gas handling capacity, but has the disadvantages of poor dust removal effect of small particles, cumbersome cleaning and replacement of the bag, and reduced dust removal efficiency due to wear of the bag. The wet dust collector has better dust removal effect for small particles, but has large water consumption and cumbersome wastewater treatment.

[0007] Based on this, the present application designs a melon seed dust removal device to solve the above problems SUMMARY
