Description
Technical Field
The invention belongs to the technical field of air filtering equipment, and particularly relates to air filtering equipment with an automatic back-blowing cleaning mechanism.
Background
In the context of the acceleration of industrialization and urbanization processes, the quality of the atmosphere has become a central element in relation to the sustainable development of living environments and economics. The outside atmosphere is filled with a large amount of impurities such as dust, pollen, straw scraps and the like, and harmful gases such as ammonia gas, hydrogen sulfide and the like generated by various production activities can be diffused in the atmosphere wantonly and possibly reintroduced into the purification system by the air purification equipment. Once the pollutants are continuously accumulated in the atmosphere, serious threat can be caused to a biological respiratory system, the incidence rate of respiratory diseases is greatly improved, severe weather such as acid rain, haze and the like can be caused to frequently occur, the ecological environment is irreversibly damaged, even an outdoor water source and crops can be possibly polluted, and the safety of the whole food chain is further endangered.
In order to effectively solve the problem of air pollution, the importance of the air purifying equipment in the environment protection field is increasingly prominent. At present, the air purifying device widely applied mainly introduces external air into a ventilation pipeline by means of a fan, and then purifies the air through a filter arranged in the pipeline, and finally outputs cleaner air. The primary filter is used as a first defense line of a purification process, plays a role in intercepting most of particulate impurities in the atmosphere, and is expected to provide clean air meeting the standard for a specific closed space after being subjected to multistage filtering links such as a sub-efficient filter and the like. However, the existing air purifying device exposes a plurality of troublesome problems in actual operation, and severely restricts the purifying efficiency and economic benefit.
The traditional primary filter mostly adopts a flat plate type filter material design, has limited contact area with air, and is difficult to fully adsorb and capture harmful components such as ammonia, hydrogen sulfide and the like when treating a complex atmospheric environment containing various harmful gases. This makes the purified air still have a lot of harmful gas left therein, and the severe requirements for guaranteeing the air quality of biological health are far from being met, and the biological health condition in such environment for a long time is worry.
The cleaning and maintaining process of the existing primary filter is complicated and has low efficiency. When cleaning, the equipment must be shut down first, the primary filter is detached from the ventilating duct with care of the manpower, the new filter material is replaced, then the filter material is reinstalled and reset, and then the replaced filter material is cleaned. The process not only consumes a great deal of manpower and time cost, but also has higher requirements on the professional skills of operators. Once the installation is deviated, the sealing performance and the filtering effect of the filter are greatly reduced, so that the equipment is unstable in operation and cannot continuously and stably output clean air. In addition, the additional filter cleaning work further adds to the operating costs.
The traditional manual cleaning mode is difficult to realize comprehensive deep cleaning of the primary filter. In the disassembly and assembly process, it is difficult to carefully inspect and thoroughly clean each place of the filter media due to the limitations of the operation space and the cleaning tool. For example, gaps between the multi-layered flat filter materials are narrow, and conventional cleaning tools are difficult to penetrate therein, resulting in a large amount of impurities remaining for a long period of time. Moreover, the edge part of the flat plate type filter material is easy to be ignored in operation, and impurities are accumulated continuously, so that the integral filtering effect of the filter is seriously affected.
The complex airflow challenge is to cope with the weakness that the airflow condition in the ventilating duct is extremely complex, and impurities in the airflow can be unevenly attached to the filter material in the long-term use process of the primary filter. Especially at the corners of the duct, the air flow will form turbulence, resulting in an increased tendency for impurities to accumulate on the filter medium on the side of the filter adjacent the corners. The traditional cleaning method lacks an effective solution to the problem of impurity accumulation caused by the special air flow condition, and is difficult to thoroughly remove impurities at the positions, so that the overall cleaning effect is greatly reduced, and high-quality purified air cannot be continuously and stably provided for the closed space.

S4, as the sliding block 26 moves, the driven rod 21 is driven to be inserted into the straight groove frame 44, the driven rod 21 is positioned at the top of the straight groove frame 44, the straight groove frame 44 can be rotated by the start of the driving motor 43, the driven rod 21 is pushed by the straight groove frame 44, the driven rod 21 moves downwards and simultaneously rotates circumferentially, the reducer pipe 2 is driven to blow air to a port for air outlet in a circular track, and meanwhile, the electric telescopic rod 42 is started to enable the telescopic end to reciprocate, so that the rotating frame 41 drives the driving motor 43 and the straight groove frame 44 to swing, and finally, the reducer pipe 2 can blow downwards and can swing left and right, so that blown compressed air can fully cover the V-shaped filter material 11 until the back-blowing cleaning work is completed;
s5, in the process that the reducing pipe 2 reversely blows the V-shaped filter material 11 until cleaning is completed, the V-shaped filter material 11 drives the cross rod 51 to continuously ascend and move, the connecting block rod 54 moves to be in contact with the inclined rail frame 55, the inclined surface of the inclined rail frame 55 presses the connecting block rod 54 to enable the clamping block 53 to be pulled out of the bayonet of the cross rod 51 under the force of the clamping block 53, the clamping spring 56 is deformed under the force, and when the clamping block 53 is pulled out, the limiting plate 52 falls off under the self weight of the clamping block;
s6, after back blowing cleaning, the ventilating duct 1 and the primary filter can be put into normal use, in the use process, the V-shaped filter material 11 can absorb impurities to gradually increase dead weight, the cross rod 51 is caused to drive the limiting plate 52 to press the sliding block 26 through the inclined surface, the sliding block 26 and the sliding ring 210 move towards the direction of the universal coupling 3, the sliding block 26 is caused to pass through the connecting rod 27, the elastic sheet 22 is driven to rotate, the diameter of the air outlet port of the reducer pipe 2 is enlarged, and the initial state is restored.
