Technical Field

The invention belongs to the field of air dust removal, flying dust and wadding, and particularly relates to an unpowered dust removal mechanism and a fresh air system.

Background

The cyclone dust removing mechanism is a common mechanism for separating dust and air by using centrifugal force, and comprises a shell, an air inlet, a spiral air duct, an air outlet and a dust outlet. The existing cyclone dust removal mechanism needs a fan and the like to provide suction force to enable gas to be treated to enter a shell to do high-speed spiral motion, and dust and the like are thrown to a side wall through centrifugal force to be discharged from a dust outlet. The filtered air leaves from the air outlet near the air inlet through a channel in the center of the cyclone dust removal pipeline. The gas can do high-speed spiral motion only with power, so as to achieve the effect of dust removal.

The fresh air system is a set of independent air processing system consisting of an air supply system and an air exhaust system and is divided into a pipeline type fresh air system and a pipeline-free fresh air system. The pipeline type fresh air system consists of a fresh air fan and pipeline accessories, outdoor air is purified by the fresh air fan and is led into a room, and indoor air is discharged through a pipeline; the ductless fresh air system is composed of a fresh air fan, and the fresh air fan is used for purifying outdoor air and guiding the outdoor air into a room. Relatively speaking, the pipeline type fresh air system is more suitable for being used in industrial or large-area office areas due to large engineering quantity, and the pipeline-free fresh air system is more suitable for being used in families due to convenient installation.

The existing fresh air system needs a fan or a fan and the like to suck outside air into a room and is used after the processes of filtering and the like. This method requires power to achieve the air exchange result. Furthermore, when the quality of the outdoor air is good, no dust, impurities, etc. are present in the outdoor air. Only plant dust such as pollen, flying cotton and the like exists, and air can directly enter a room only by separating the part of the dust.

Detailed Description

As shown in fig. 1-3, the unpowered dust removing mechanism comprises a housing 7, wherein the housing 7 is provided with an air inlet 2, an air outlet 3 and a dust outlet 4, and a spiral air duct is arranged in the housing 7. The shell 7 both ends opening, and air intake 2 and air outlet 3 set up respectively at the both ends of shell 7, and air intake 2 is located the great open end of shell 7, and air outlet 3 is located the less open end of shell 7, and the dust outlet 4 position is close to air outlet 3, forms the throat effect between air intake 2 and the air outlet 3. Because a narrow tube effect is formed between the air inlet 2 and the air outlet 3, the flow passage of the air flow is enlarged, and enough centrifugal force can be provided under the condition of no fan, so that the function of unpowered dust removal is realized.

A spiral air deflector 8 is arranged in the shell 7, and a spiral air duct is formed between the spiral air deflector 8 and the inner wall of the shell 7. The shell 7 can be internally provided with one spiral air deflector 8 or at least two spiral air deflectors 8, and each spiral air deflector 8 and the inner wall of the shell 7 form a spiral air duct. Due to the influence of the other spiral wind deflectors 8, each spiral wind channel is actually enclosed by each spiral wind deflector 8 and the casing 7 and the adjacent spiral wind deflectors 8. The shape, the spiral direction and the helix angle of each spiral wind deflector 8 can be the same. The head ends of the spiral air deflectors 8 are uniformly distributed on the circumference of the shell 7 at the air inlet 2. The shape of the spiral wind deflector 8 can be various. The spiral air ducts are not communicated with each other. The middle can be separated by a column. The post may be located at the central axis of the housing 7. The head end and the tail end of the spiral air deflector 8 are respectively arranged at the air inlet 2 and the air outlet 3. And one side of the two sides of the spiral air deflector 8 is connected with the shell 7, and the other side is connected with the upright post. Of course, other mechanisms may be used.

The tail end of the spiral air deflector 8 is connected with the inlet end of a clean air pipeline 9, the outer diameter of the clean air pipeline 9 is smaller than the inner diameter of a shell 7 at the joint of the clean air pipeline 9 and the spiral air deflector 8, and the outlet end of the clean air pipeline 9 is an air outlet 3. A dust outlet 4 is formed between the outer wall of the clean air pipeline 9 and the inner wall of the shell 7. The tail end of the spiral air deflector 8 refers to the end of the spiral air deflector 8 opposite to the air inlet 2 of the shell. The head end of the spiral air deflector 8 means that the spiral air deflector 8 is positioned at one end of the air inlet 2 of the shell. For a mechanism with only one spiral air duct, the dust outlet 4 may also be arranged on the side wall of the housing 7 near one end of the air outlet 2.

The spiral air deflector 8 may extend to the air outlet inside the clean air duct 9. The portion of the spiral air deflector 8 between the outer wall of the clean air duct 9 and the housing 7 may also extend to the dust outlet. The outer shape of the shell 7 can be trumpet-shaped or cone-shaped, and the outer diameter of the shell at the air inlet 2 is the largest. Like this the air current is at the in-process from air intake 2 to air outlet 3, because the passageway limit is narrow, the air current velocity grow, and centrifugal force grow more easily throws away dust, pollen, flying wadding etc..

The fresh air system applying the unpowered cyclone dust removal mechanism comprises a fresh air host 10, wherein the fresh air host 10 is communicated with each indoor air inlet, each indoor air outlet and each outdoor air outlet through a pipeline. The fresh air host 10 is connected with an air outlet 3 of the unpowered dust removing mechanism 1 through an air inlet pipeline 6, and an air inlet 2 of the unpowered dust removing mechanism 1 is arranged outdoors. The conventional fresh air main unit 10 includes a blower or a fan, and external air needs to be sucked by the blower or the fan. The fresh air host 10 of the present application may not include a power mechanism.

Unpowered dust removal mechanism 1 sets up outdoors, still sets up the wind vane outdoors, and the wind vane includes stand and round stand pivoted head 5. The unpowered dust removing mechanism 1 is connected with the head part 5 of the wind vane, and the head part 5 of the wind vane rotates along with the wind direction to enable the air inlet 2 of the unpowered dust removing mechanism 1 to always face the wind blowing direction. The size and position relation between the unpowered dust removing mechanism 1 and the head part 5 of the wind vane ensures the normal use of the wind vane in the specific design.

The pipeline at the air outlet 3 of the unpowered dust removing mechanism 1 is rotatably connected with an air inlet pipeline 6; the air inlet pipeline 6 is used as a vertical column of a wind vane, the head part 5 of the wind vane is arranged on the unpowered dust removing mechanism 1, and the wind vane and the unpowered dust removing mechanism 1 rotate around the air inlet pipeline 6. The air inlet pipe 6 can be partially arranged outdoors and can be higher, and outdoor air can be conveniently collected. The material can be harder materials such as metal to realize the function of the upright post.

The unpowered dust removing mechanism 1 is arranged on a roof; and the wind energy is more easily utilized due to the spaciousness. And a conducting layer with a negative electric field is arranged on the inner wall of the shell 7, the spiral air deflector 8 and the air inlet pipeline 6, so that negative oxygen ions in the air are prevented from disappearing when entering the cyclone dust removal mechanism. A positively charged metal rod 11 may also be provided on the roof to attract and collect negative oxygen ions so that more negative oxygen ions can enter the room.

A filtering device and a powder wadding collecting device can be arranged between the fresh air host machine 10 and the air inlet pipeline 6 for further processing residual dust, flying wadding and the like in the air. A heat exchange system can be arranged in the fresh air host. These are prior art and will not be described in detail.
