TECHNICAL FIELD
[0001] The utility model relates to central air conditioning air intake dust removal technical field, specifically a central air conditioning air intake dust removal device. BACKGROUND
[0002] In modern building environment, central air conditioning system plays a vital role, it not only provides comfortable indoor temperature for people, but also has a significant influence on indoor air quality. However, with the acceleration of industrialization process and the change of natural environment, the pollutants in the atmosphere are increasing, and the air is full of a lot of dust, impurities, harmful gases and microorganisms, etc. These pollutants enter the air conditioning system with the intake air during the operation of the central air conditioning, causing a series of serious problems.
[0003] The traditional central air conditioning air intake treatment method usually only uses simple filter screen filtering, and this single filtering method has many defects. First of all, the filtering precision of ordinary filter screen is limited, and the interception effect is not good for small particles such as PM2.5 and below, resulting in a large number of small particles entering the air conditioner, which accumulates on the surface of the evaporator, condenser and other heat exchange components, forming a dirt layer. This not only reduces the heat exchange efficiency, greatly increases the energy consumption of the air conditioner, but also affects the refrigeration or heating performance of the air conditioner, shortens the service life of the equipment, increases the maintenance cost and energy consumption, and does not meet the development concept of modern energy saving and environmental protection.
[0004] Secondly, in some equipment using the principle of electrostatic adsorption for dust removal, although it has a certain adsorption capacity for small particles, it often produces ozone and other products. Ozone has strong oxidizing property, and excessive ozone emission into indoor air can cause irritation and damage to respiratory tract, eyes and other organs of human body, causing symptoms such as cough, difficulty in breathing, eye pain, etc. Long-term exposure to high concentration ozone environment may cause more serious health problems, such as respiratory diseases, cardiovascular diseases, etc., which seriously threaten the health and safety of indoor personnel.
[0005] In addition, the existing air intake dust removal device is not reasonable in structure design, and the installation and maintenance of each part are more complicated, for example, the replacement of filter screen often needs complex disassembly steps, and due to the fixed structure, it is difficult to increase the filtering area in limited space, resulting in difficult improvement of filtering efficiency; the dust adsorption saturation of electrostatic adsorption plate and other components after long-term use, if not cleaned in time and effectively, will cause the adsorption efficiency to drop sharply, and the traditional cleaning method usually needs manual operation, which is time-consuming and inefficient, and it is difficult to ensure the continuous and stable operation of the equipment. At the same time, manual maintenance process may cause damage to the equipment due to improper operation, further affecting the normal use and service life of the equipment.
[0006] In summary, in order to meet the multiple requirements of modern buildings on high-efficiency operation, energy saving and environmental protection of central air conditioning systems and protection of indoor air quality and personnel health, a new type of central air conditioning air inlet dust removal device is urgently needed, which can comprehensively and efficiently remove various pollutants in the air, solve many problems existing in the traditional air inlet treatment mode, promote the development and progress of central air conditioning technology, and create a more comfortable, healthy and environmentally friendly indoor environment for people.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1-6 As shown, this utility model provides a technical solution: a central air conditioning intake dust removal device, including a central pipe 1 and air inlets 12 and outlets 13 at both ends of the central pipe 1. The central pipe 1 has multiple sets of slots 8, grooves 9 and placement slots 10. A filter screen 5, an ozone decomposition plate 6, an electrostatic adsorption plate 7 and a collection bag 2 are sequentially engaged in the slots 8 from right to left. An inclined baffle 14 is fixed to the left side of the collection bag 2 inside the central pipe 1. The layered design of the slots 8, grooves 9 and placement slots 10 allows the key components, such as the filter screen 5, ozone decomposition plate 6, electrostatic adsorption plate 7 and collection bag 2, to be installed in an orderly and stable manner inside the central pipe 1, forming a compact and efficient dust removal system. Through the cooperation between the components, the air is purified sequentially from the air inlet 12 to the air outlet 13, effectively removing dust, impurities and harmful gases from the air, improving the air quality entering the central air conditioning system, and thus improving the operating efficiency and service life of the air conditioning system.
[0028] The outer surface of the central pipeline 1 is fixed with a rotating motor 4 through a support plate 3, the output shaft of the rotating motor 4 is fixed with a rotating shaft 19 penetrating between the central pipeline 1 and the baffle 14, the surface of the rotating shaft 19 is sleeved with a bearing 18, the bearing 18 is embedded in the central pipeline 1 and the baffle 14, a sliding groove 20 is formed in the rotating shaft 19, a sliding rod 23 is arranged in the sliding groove 20, the sliding rod 23 is fixed with a soft brush 25 penetrating through the rotating shaft 19, and the surface of the sliding rod 23 is sleeved with a spring 24 which can make the soft brush 25 lap the electrostatic adsorption plate 7, one end of the spring 24 is lapped with the side surface of the rotating shaft 19, a limiting groove 21 is formed in the sliding groove 20, and a limiting block 22 which slides with the sliding rod 23 is arranged in the limiting groove 21, the rotating motor 4 drives the rotating shaft 19 to rotate, so that the soft brush 25 can regularly clean the electrostatic adsorption plate 7, the design of the spring 24 ensures that the soft brush 25 is always in close contact with the electrostatic adsorption plate 7, and the cleaning effect is ensured, even if the surface of the electrostatic adsorption plate 7 is uneven due to long-term adsorption of dust, the dust can also be effectively cleaned and fall into the collecting bag 2, the automatic cleaning function greatly reduces the workload and frequency of manual maintenance, improves the automation degree and reliability of the dust removal device, ensures that the electrostatic adsorption plate 7 is always in good working condition, maintains the high-efficiency adsorption capacity of the electrostatic adsorption plate 7 to small particles, thereby continuously and stably providing clean air for the central air conditioner, ensuring the efficient operation of the air conditioning system, and reducing the risk of dust removal effect decline and equipment failure caused by untimely manual maintenance, and at the same time, when the electrostatic adsorption plate 7 is not cleaned, the airflow in the central pipeline 1 blows the sliding rod 23 and the soft brush 25 and compresses the spring 24 to realize the flow of the gas in the central pipeline 1.
[0029] Specifically, the placing groove 10 is provided with a placing block 11, the placing block 11 is clamped with the bottom end of the filter screen 5, the filter screens 5 are connected through the hinge 17, and the placing block 11 is connected with the central pipeline 1 through the bolt 16.
[0030] The above-mentioned folding filter screen 5 design greatly increases the filtering area, under the same space occupation, can more fully intercept large particles of dust, hair, flocculation and other impurities in the air, reduces the initial pollutant content of the air entering the subsequent purification link, reduces the working burden of the subsequent components, improves the efficiency and service life of the whole dust removal device, at the same time, through the fixing mode of the placing block 11 and the bolt 16, the installation and disassembly of the filter screen 5 become simple and fast, which is convenient for regular cleaning or replacement of the filter screen 5, reduces the maintenance cost and difficulty, and ensures the stability and persistence of the filtering effect
[0031] Specifically, the ozone decomposition plate 6 and the electrostatic adsorption plate 7 are clamped at the bottom end of the central pipeline 1 in the groove 9 opened at the bottom end of the central pipeline 1, and are fixed with the central pipeline 1 through the bolts 16. The ozone decomposition plate 6 can efficiently decompose the ozone that may be generated in the electrostatic adsorption process. Ozone is a strong oxidizing agent, and excessive ozone can cause irritation and damage to the respiratory tract, eyes and other parts of the human body. By decomposing the ozone into harmless oxygen through the ozone decomposition plate 6, the purification effect of the dust removal device is ensured, secondary pollution is avoided, the health of indoor personnel is protected, and the service life of the internal parts of the air conditioner is also prolonged. The electrostatic adsorption plate 7 is located behind the ozone decomposition plate 6, and can effectively capture tiny particles in the air, such as PM2.5 and even smaller pollutant particles, by using the principle of electrostatic adsorption. These tiny particles are often difficult to completely remove by traditional filtering methods. The electrostatic adsorption effect can adsorb them on the electrostatic adsorption plate 7, which improves the purification degree of the air and makes the air entering the central air conditioner cleaner, reduces the accumulation of dust in the air conditioner, and thus reduces the occurrence of problems such as heat exchange efficiency reduction and energy consumption increase caused by dust accumulation in the air conditioner, helps to maintain the good performance of the air conditioner, reduces the operating cost, and also creates a cleaner air environment for the indoor, reducing the potential harm of tiny particles to human lungs and other organs.

An inclined baffle 14 is fixed inside the central pipeline 1 at the left side of the collecting bag 2. The collecting bag 2 is used to collect the dust and other impurities intercepted from the electrostatic adsorption plate 7. The setting of the baffle 14 plays a role in guiding the dust and impurities to fall into the collecting bag 2, preventing them from flying again in the central pipeline 1, and ensuring the efficiency and stability of the dust removal process. Through the fixing mode of the fixing plate 15 and the bolts 16, the collecting bag 2 can be easily cleaned regularly, avoiding the backflow of dust due to the overflow of the collecting bag 2, and affecting the dust removal effect and air quality.
