Fresh air system capable of automatically cleaning filter screen

Abstract

The invention discloses a fresh air system capable of automatically cleaning a filter screen. The fresh air system comprises an air inlet fan and a filtering device. The filtering device comprises a shell, a fixed frame and an ash removal box, multiple air inlets are formed in the shell, an insect-proof net is arranged on the side, facing the fixed frame, of the shell, and a filter screen frame isarranged at the end, away from the shell, of the fixed frame. A dust suction fan, a dust blowing fan and a driving motor are arranged in the ash removal box, a mounting base is arranged at one end ofthe fixed frame, and a wind pressure sensor and a controller are arranged in the mounting base. Software control and communication networking technologies are utilized, parameters output by the sensor are used for replacing manual judgment, the system is more intelligent, manpower and material resources are saved, and the running reliability and the working efficiency of equipment are improved. The filtering device is externally arranged, so that the indoor occupied area is small. The system is free of maintenance, timely self cleaning is achieved through cooperation of the wind pressure sensor and the ash removal box, the situation that a product cannot run normally due to blockage of two stages of filter screens is avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to a fresh air system for automatically cleaning filter screens. Background technique [0002] The power consumption of communication on-network equipment, as the basic power consumption of communication base stations, is a rigid demand. There is almost no means of substantial energy saving in the existing technology. In order to achieve energy saving and consumption reduction, we can only seek breakthroughs in the power consumption of air conditioners. In principle, the use of fresh air system is a reasonable choice under the current technical conditions, which can minimize the use time and frequency of air conditioners in daily maintenance. [0003] The principle of the fresh air system is to introduce a large amount of clean outdoor air to cool down the interior of the communication base station by forced ventilation, and to discharge the hot air inside the base station...

AI Technical Summary

Problems solved by technology

[0005] (1) The air intake filter is seriously blocked by dust

[0006] At present, the air inlet filter and insect-proof net have the problem of dirty filter caused by catkins, catkins, mosquitoes, etc., as well as large particles of dust. Manpower is often required to go to the site for cleaning and replacement, which is not suitable for unattended communication base stations.

Once the filter screen is blocked, the ventilation will fail, and this problem has not been effectively solved

[0007] (2) High cost of maintenance labor and consumables

[0008] The maintenance is cumbersome and frequent, and the consumption of consumables is too large, which leads to the high operating cost of the equipment itself. A large number of fresh air systems cannot be maintained and repaired in time, and even work with diseases, or even stop running, and cannot realize its energy-saving function.

[0009] (3) There is a problem with the control system

[0010] A fresh air system that automatically cleans the filter screen and has a self-starting function when there is no incoming power. The fresh air system cannot start automatically after the power is restored;

[0011] B. The control panel fails, and the linkage control between the fresh air system and the air conditioner fails
