A drum screen device

Abstract

The invention provides a drum screen device comprising a support (1), a feeding hopper (2), a bin door (3), a cylindrical screen mesh (4), a rotating shaft (5), a motor (6) and a scraping plate (7). The feeding hopper (2) is fixed on the support (1); the bin door (3) is located under the feeding hopper (2); the cylindrical screen mesh (4) is fixed on the rotating shaft (5); the scraping plate (7) is fixed on the cylindrical screen mesh (4); the rotating shaft (5) and the motor (6) are fixed on the support (1); the motor (6) is connected with the rotating shaft (5). The drum screen device has the advantages of scientific design, simple structure, convenient operation, smooth screening and mesh clogging prevention, clear classification, small vibration, low noise and long service life. The drum screen device can be widely applied to the filter, screening and impurity removal work for powdery materials, in particular the filter and impurity removal for saw dust type materials, and thus is an ideal product for replacing the conventional horizontal screen type screening machine and is worthy of vigorous promotion.

Description

technical field [0001] The invention relates to the field of edible fungus production machinery, in particular to a rolling sieve device. Background technique [0002] Nowadays, edible fungi are popular among people because of their characteristics of being green, organic, nutritious, and healthy. Our common shiitake mushrooms, oyster mushrooms, enoki mushrooms, black fungus, white fungus, etc. all belong to the category of edible fungi. In the process of producing edible fungi, common raw materials include cottonseed husks, sugar cane, sawdust, and corncobs, and common auxiliary materials include bran, corn flour, rice bran, lime, gypsum, etc. Production practice shows that for different raw materials, as long as we add appropriate amount of auxiliary materials to achieve nutritional balance, the efficiency will be ideal from a biological point of view. [0003] Among them, sawdust is one of the most commonly used raw materials. Generally, wood chips on the market cannot...

AI Technical Summary

Problems solved by technology

In production practice, it is found that there are four major problems: first, the screen is easily blocked by materials and impurities, and manual tapping is required to remove the clogged debris, which affects the filtration speed and the effect of impurity removal; second, the classification is not clear, and the entire screen The sieve holes are all the same size, so the filtered sawdust cannot be finely sorted and stacked according to the particle size; the third is strong vibration and high noise; the fourth is short service life and prone to failure
