Dust removal device for air filter cartridge

Abstract

The invention relates to a dust removal device for an air filter cartridge. The dust removal device is provided with a frame, an electric control panel, a dust removal chamber with a closed structure, and a sealed dust collection device, wherein a double-roller mechanism and a nozzle guide rod mechanism capable of spraying air to remove dust inside and outside are arranged in the dust removal chamber; under the drive of an speed-adjustable motor and a feed screw nut, an inner nozzle and an outer nozzle in the nozzle guide rod mechanism can do uniform rectilinear motion to and fro inside and outside the air filter cartridge to be dedusted and uniformly apply compressed air to the internal and external surfaces of the air filter cartridge for dust removal; the dust collection device consists of a vacuum pump and a dust collection chamber positioned below the vacuum pump; and one side of the frame is provided with a detection platform for detecting whether the filter cartridge is broken or not. The dust removal device has the dust removal rate of over 95 percent, can realize dust removal and detection functions, is easy to operate and control, can blow the air uniformly in multiple directions, does not damage the air filter cartridge, is labor-saving, time-saving, safe and environmental-friendly, is favorable for protecting the body health of workers and improving labor efficiency, saves production and operation cost, and can clean and maintain various types of cylindrical air filter cartridges in engines of all Europe III buses and other transport vehicles, ships and the like.

Description

technical field [0001] The invention relates to a dust removal device for engines such as vehicles, in particular to an air filter dust removal device, which can be used for cleaning and maintenance of cylindrical air filters of various specifications and models in engines such as transport vehicles, passenger cars, and ships. Background technique [0002] For various engines that use air sources, in order to prolong the service life of the engine and reduce unnecessary wear and tear, various types of cylindrical air filter elements are used as important parts of various types of engines. Since most of the air filter elements of the engine It is a paper product. At present, when cleaning and maintaining the air filter element, there are deficiencies: [0003] 1. For example, in various existing automobile repair points or maintenance workshops, the air filter element (tube) is often maintained by manual dust removal.

AI Technical Summary

Problems solved by technology

[0003] 1. For example, in various existing automobile repair points or maintenance workshops, the air filter element (tube) is often maintained by manual dust removal. The maintenance operator often uses a nozzle with compressed air on an inflatable leather tube to aim at the circle The surface of the cylindrical air filter element is impacted to remove the dust attached to the surface, which not only pollutes the environment, but also seriously affects the respiratory health of the workers, and the air pressure of the inflatable hose nozzle is difficult to control and unscientific. When it exceeds the capacity that the paper air filter element can withstand Air pressure (Note: The impact range of high-pressure air that the engine paper air filter element can withstand is limited), often causing damage to the air filter element (tube), which has to be replaced frequently, resulting in huge waste, taking urban buses as an example , there are many vehicles belonging to the public transport group, and they operate non-stop every morning and evening, resulting in intensive vehicle maintenance. Since the air filter element (tube) is an important part of the engine, the price of each set is nearly 300 yuan, which is relatively expensive. Fuzhou Public Transport Group The company as an example, because it needs to spend more than RMB 1.15 million per year to replace the damaged air filter element with the existing maintenance technology, which undoubtedly greatly increases the operating cost of the bus company

[0004] 2. In the process of dust removal and maintenance of the filter element with the existing manual method, when the paper filter element is slightly damaged, it is not easy to be found. When it is reused, its ability to filter dust is greatly reduced, so that fine dust can pass through the filter The core enters the cylinder of the engine, causing early wear and tear of the engine and shortening the life of the engine

[0005] 3. In addition, it is difficult to blow air in multiple directions and evenly with the inflatable hose nozzle of the existing manual method, because the air pressure of the nozzle is not only difficult to control, but also unscientific, and it is easy to damage the filter element, resulting in troublesome operation and time-consuming Workers, at least 2 or more maintenance workers must cooperate to ensure the quality of maintenance

[0006] To sum up, in the existing dust removal equipment, there is no suitable special vehicle and other engine air filter dust removal equipment available for use
