Vacuum drawing type dust removal hopper

Abstract

The invention discloses a vacuum drawing type dust removal hopper. The vacuum drawing type dust removal hopper comprises a support, a hopper body and a dust removal device. The hopper body is arrangedon a rack, the hopper body is connected with the dust removal device, a connecting box is arranged on the hopper body, and communicates with the hopper body, discharging ends on the two sides of theconnecting box communicate with the feeding end of a connecting pipe, the discharging end of the connecting pipe is connected with the feeding end of an exhaust pipe through a connecting flange, a filter bag is arranged at the connecting position of the discharging end of the connecting pipe and the feeding end of the exhaust pipe, a dual-shaft motor is arranged on the bottom of the connecting box, the output end of the dual-shaft motor is connected with a rotating shaft, the rotating shaft is connected with two sets of rotating rods through two sets of transmission parts, and one ends of therotating rods penetrate through the connecting pipe and are rotatably connected with the connecting pipe, and are further connected with fan blades. According to the vacuum drawing type dust removal hopper, through filter separation, environment-friendly clean air is obtained, and is exhausted into the atmosphere, the raised dust during hopper work can be greatly reduced, and the dust removal efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of dust removal funnels, in particular to a vacuum suction type dust removal funnel. Background technique [0002] Dust refers to solid particles with a small diameter, which are inhaled into the respiratory tract by the human body, and most of them are inhaled and then exhaled. In the absence of resistance, the inhaled dust particles will enter the respiratory bronchioles, alveolar ducts and alveoli in the gas exchange area after passing through the trachea, main bronchi, and bronchioles, and produce toxic effects during the process of entering. Gas exchange function. In fact, after being inhaled into the respiratory tract, respirable dust settles in the respiratory tract mainly through impact, gravity deposition, dispersion (also known as Brownian motion), electrostatic deposition, and interception, and only a very small part of the dust can enter the alveolar area. Dust particles themselves contain soluble substa...

Problems solved by technology

The funnels currently commonly used basically do not have the function of dust removal, resulting in the dust at the loading site "covering the sky and the sun", which not only seriously affects the physical and mental health of the on-site staff and nearby residents, but also causes a large amount of cargo loss.

Although some wharves and freight yards have purchased funnels with dust removal functions, these funnels either have poor dust removal effects, low work efficiency, high power consumption, or a combination of various defects, resulting in these so-called "dust removal funnels". Most of them are used as decorations for visits and inspections, and almost none of them are actually put into use.
