A dust removal device for a vibrating screen

Abstract

The invention discloses a dust removing device for a vibrating screen, and relates to the technical field of vibrating screens. Due to the fact that an upper window is formed in a screen box, a largeamount of dust can be generated on the upper side of a screen along with continuous up-down jumping of materials, and the dust can be blown out from the upper window of the screen box, the environmentcan be polluted, and adverse effects can be caused to surrounding workers. The scheme comprises a screen box which is obliquely arranged; an upper window is formed in the upper side of the screen box, two dust collecting strip shells are fixed on the upper wall of the screen box, and dust collecting strip openings are formed in the side walls, close to the upper window, of the dust collecting strip shells; a dust collecting box is arranged on one side of the screen box, dust collecting pipes are connected to the dust collecting strip shells and the dust collecting pipes are in communication with the dust collecting box; and two air wall generating devices are connected in the upper window, each air wall generating device comprises an air outlet shell, a cross-flow fan blade and a drivingmotor, an air inlet is formed in the upper wall of the air outlet shell, and an air outlet strip opening is formed in the side wall of the air outlet shell. The two air wall generating devices can form two air walls for dust separation and dust removal, so that the dust is isolated to the outside, and meanwhile, the dust can be collected in a centralized mode.

Description

technical field [0001] The invention relates to the technical field of vibrating screens, in particular to a dust removal device for vibrating screens. Background technique [0002] Vibrating screens are mainly divided into linear vibrating screens, circular vibrating screens, rotary vibrating screens, and exciting vibrating screens. They are generally composed of vibrators, screen boxes, supporting or suspension devices, and transmission devices. The vibrating screen has a wide range of applications, mainly used in mining, coal, smelting, building materials, refractory materials, light industry, chemical industry, medicine, food and other industries. [0003] In the field of sand and gravel screening, vibrating screens generally include a base, a screen box above the base, a spring set connected between the base and the screen box, and a screen fixed in the screen box. The screen box and the screen are inclined. Setting, a feed hopper is fixed on the top of the screen box,...

Problems solved by technology

[0004] However, during the working process of the vibrating screen, since there is an upper window on the upper side of the screen box (to facilitate the cleaning of the screen), as the materials continue to jump up and down, a large amount of dust will be generated on the upper side of the screen and float out from the upper window of the screen box. Not only pollute the environment, but also adversely affect the surrounding staff
