Problems solved by technology

The above-mentioned ventilation system has the following problems. Because the air contains a lot of dust, a filter screen will be installed at the air inlet or outlet of the pipeline. Like Beijing or near construction, where the dust is relatively large, the filter screen needs to be cleaned frequently , because the disassembly and assembly of the filter screen is very troublesome, it is necessary to design an intelligent ventilation system that can clean itself

Embodiment

[0028] Example: Reference Figure 1-3 , an intelligent ventilation and purification system for buildings, comprising a chassis 11, an air inlet duct 13 and an air outlet duct 14 arranged on the chassis 11, a fan 12 is arranged inside the chassis 11, and the port position of the air inlet duct 13 is set for filtering Filter cloth for solid particles2. After the blower fan 12 works, the blower fan 12 continuously draws the outdoor wind into the room, and the outdoor air is more pure after being filtered by the filter cloth 2, so as to ensure that the indoor air is kept clean all the time, and also helps to remove indoor peculiar smell and improve living or working environment.

[0029] refer to Figure 2-3 The cabinet 11 is rotatably connected with some guide rollers 21 and is fixed with a first motor 22 for driving the guide rollers 21 to rotate. The filter cloth 2 is ring-shaped and coiled on the guide rollers 21. After the filter holes on the filter cloth 2 are blocked by ...

Embodiment 2

[0037] Embodiment 2, refer to Figure 2-7 , a building intelligent ventilation and purification system, including a control system for controlling the mechanical structure in Embodiment 1, the control system includes a control system for controlling the first motor 22, the second motor 53, the servo motor 44 and the fan 12 device, an air quality sensor for detecting indoor air quality, and a flow sensor for detecting gas flow in the pipeline; when the air quality sensor detects that the indoor air quality is poor, the controller controls the fan 12 to work; When the air intake of 2 is lower than the set threshold, the controller controls the first motor 22, the second motor 53 and the servo motor 44 to work, so that the clean filter cloth 2 corresponds to the position of the air intake pipe 13, thereby realizing intelligent ventilation. The controller is preferably a PLC controller.

[0038] refer to Figure 7 , The controller is provided with a short message editing module,...

Abstract

The invention relates to an intelligent ventilation and purification system for buildings, which includes a case, an air inlet pipe and an air outlet pipe arranged on the case, a fan is arranged inside the case, and several guide rollers and fixed There is a first motor for driving the guide roller to rotate. The guide roller is covered with a ring-shaped filter cloth. The filter cloth corresponds to the air inlet pipe, so that the control passes through the filter cloth and enters the cabinet. The inside of the cabinet is located The bottom of the air duct is provided with a cleaning box for holding water, the lower end of the filter cloth is located in the cleaning box, and the cleaning box is provided with a cleaning roller sliding along an elliptical track and a swing mechanism for driving the cleaning roller to swing; After the filter cloth located at the position of the air inlet pipe fails, the guide roller rotates so that the failed filter cloth enters the cleaning box, and the reciprocating sliding of the cleaning roller drives the filter cloth to swing in the water. The invention has the effect of automatically controlling the fan according to the indoor air quality to ensure that the indoor air quality is always kept fresh.

Description

technical field [0001] The invention relates to the field of ventilation systems, more specifically, it relates to an intelligent ventilation and purification system on buildings. Background technique [0002] The building ventilation system is one of the important components of the building. Through the ventilation system, the gas inside and outside the building can be exchanged to ensure that people can always breathe fresh air. [0003] The existing ventilation system is composed of pipes and fans. The fans are used as the source of power to circulate the wind. The outlets of the pipes are distributed in various rooms or in various positions in the same house. The above-mentioned ventilation system has the following problems. Because the air contains a lot of dust, a filter screen will be installed at the air inlet or outlet of the pipeline. Like Beijing or near construction, where the dust is relatively large, the filter screen needs to be cleaned frequently , because t...
