Internal steering type dust removal and ventilation device

Abstract

The invention relates to the field of ventilation equipment, and specifically relates to an internal steering type dust removal and ventilation device which comprises a horizontally arranged support mounting cylinder, a plurality of fixed mounting plates are outwards arranged at the two ends of the support mounting cylinder at equal angles; fixed mounting holes are formed in the fixed mounting plates in a penetrating manner; a rotary mounting cylinder is horizontally arranged in the middle of the interior of the support mounting cylinder; rotary mounting grooves are formed in the inner sides,right opposite to the upper side and the lower side of the rotary mounting cylinder, of the support mounting cylinder; a steering turntable is horizontally arranged in the middle of the upper end of the rotary mounting cylinder through a connecting column; an internal steering rotating structure is adopted, the interior of the device can be directly steered without power off; the problem that a traditional device needs to be powered off for reversing driving is avoided, the problem that the flow guiding capacity of impeller rotation is reduced after reversing driving is avoided, through a guiding installation structure, the device has good maintainability, the service life of the device is remarkably prolonged, a seepage adsorption structure is adopted, and the device can always keep gooddust removing capacity.

Description

technical field [0001] The invention relates to the field of ventilation equipment, in particular to an internal steering type dust removal ventilation device. Background technique [0002] Ventilation, also known as ventilation, is to send enough fresh air into the indoor space by mechanical or natural methods, and at the same time discharge the dirty air that does not meet the hygienic requirements, so that the indoor air can meet the hygienic requirements and the needs of the production process. The various facilities that complete the ventilation work in the building are collectively referred to as ventilation equipment. Ventilation can be divided into general ventilation and local ventilation according to the scope. General ventilation, also known as dilution ventilation, is the ventilation of the entire space. Local ventilation is to directly collect the polluted air at the place where the pollutants are generated and discharge it outdoors, or directly supply fresh a...

Problems solved by technology

For example, in some high-rise office buildings and gorgeous buildings, there are obvious problems such as air quality degradation caused by poor ventilation.

[0004] The existing technology has the following problems: the building ventilation and dust removal device achieves the purpose of air circulation by sucking in the air and then filtering it. Most of the existing devices are not convenient to control the amount of air intake. In severe cases, it is inconvenient to reduce the air intake volume, which will cause damage to the user's health; the filter elements in the original device are mostly directly fixed inside the device, and the device needs to be disassembled for replacement, which is troublesome

[0005] Chinese patent (Notice No. CN209944664U) discloses a building ventilation and dust removal device. Although it can adjust the air intake and facilitate replacement, it is not practical in actual use. There are obvious defects in all aspects
