[0002] The vacuum truck is a new type of road cleaning sanitation vehicle that uses a dust removal and filtration system. It has changed the traditional way of sweeping with a disc brush and rolling brush, and has completely adopted the working principle of negative pressure direct suction to complete the work. Through the vehicle's dust removal and filtration system and automatic pulse vibration dust removal system, it effectively reduces dust pollution and simultaneously filters inhalable particles, improves air quality, reduces the content of inhalable particles in the air, and improves people's respiratory health.

[0003] However, the current vacuum cleaner still has the following problems when in use:

[0004] The vacuum cleaners currently in use use filter elements to filter dust during use. Due to their working characteristics, there is a lot of dust, and the filter elements are seriously clogged during the cleaning operation. The dust is not removed cleanly during the operation of the vacuum cleaner, resulting in reduced suction power and a gradual decrease in work efficiency. Summary of the invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a compressed air dust removal device, which determines the blockage condition of the filter element by detecting the air flow pressure. When the filter element is blocked, the compressed air is quickly dissipated to form an impact force to clear the dust outside the filter element, so as to ensure that the filter element is always in the best condition, increase the service life of the filter element, reduce costs, ensure the cleanliness of the road surface, and reduce manual labor intensity.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example: Figures 1 to 7 As shown, the present invention provides a compressed air dust removal device, comprising:

[0032] The compression mechanism 10 includes a baffle 12, an air storage tank 11 fixed to one side of the baffle 12, and a temporary storage tank 16 fixed to the other side of the baffle 12, and also includes an oil injector 13, an air intake pipe 15 and an air flow detector;

[0033] Among them, the temporary storage tank 16 is equipped with a solenoid valve 14 for controlling whether the gas flows;

[0034] The gas storage tank 11 includes an outer sleeve 111 with an air cavity inside and an inner sleeve 112 fixed inside the outer sleeve 111. The baffle 12 is provided with an air inlet hole 121. When external air is introduced, one end of the air inlet pipe 15 is connected to the air inlet hole 121, and the other end is connected to the air outlet of an external air pump. The air pump supplies air, which enters the air inlet hole 121 through the air inlet pipe 15, and then enters the air cavity K1 inside the outer sleeve 111 through the air inlet hole 121 (such as Figure 3 and Figure 7 As shown), and isolated outside the inner sleeve 112, as the air pump continuously supplies air, the gas is compressed inside the outer sleeve 111 to form compressed air. At the same time, a plurality of air outlet holes 122 are provided on the baffle 12, and the air inside the air storage tank 11 can enter the temporary storage tank 16. At this time, since the solenoid valve 14 is not opened, the compressed air does not circulate. During the vacuuming operation of the vacuum cleaner, the air flow detector 17 is used to detect the air flow pressure, and when the air flow pressure is lower than the preset threshold value, it represents that the filter element 21 is blocked. At this time, the air flow detector 17 sends a signal to the solenoid valve 14, and a connecting hole 123 is provided in the middle of the baffle 12 for connecting the inner sleeve 112 and the temporary storage tank 16. The solenoid valve 14 is started to connect the temporary storage tank 16 and the inner sleeve 112, and the compressed air inside the temporary storage tank 16 can enter the air outlet channel K2 inside the inner sleeve 112 (as shown in FIG. Figure 3 and Figure 7 As shown), and quickly emit air impact force to clean the dust outside the filter element 21;

[0035] More specifically, the inner sleeve 112 is a conical structure, and the air outlet channel K2 inside it is trumpet-shaped, which can increase the air flow speed and increase the air impact force;

[0036] As an optimization of the above technical solution, during the dust removal work of the filter element 21, the oiler 13 presets the oiling interval, such as oiling once after half an hour of work, and repeats the cycle;

[0037] Oiling is performed through the oiler 13. On the one hand, it can lubricate the rubber sleeve of the filter element 21 to prevent wear and reduce material costs. On the other hand, it can also seal the rubber sleeve of the filter element 21 to ensure the air tightness of the air intake port and support the concentric axial force of the filter element 21.

[0038] The filter mechanism 20 includes a filter element 21, a sleeve 22, a filter element housing 23, a fan frame 24, a motor 25, a fan 26 and an air gathering port 27;

[0039] Among them: the sleeve 22 is sleeved on the outside of the compression mechanism 10, the filter element 21 is sleeved on the outside of the sleeve 22, the filter element 21 is installed on the filter element housing 23, the air gathering port 27 is installed on the filter element housing 23, the fan 26 is installed on the air gathering port 27, the output shaft of the motor 25 is connected to the fan 26, the fan frame 24 is sleeved on the outside of the fan 26, and the motor 25 is installed on the fan frame 24.

[0040] When in use, the machine is started, the cleaning work begins, and the air pump starts to supply air, which enters the air storage tank 11 through the air inlet pipe 15;

[0041] The motor 25 starts, driving the fan 26 to rotate, so that the air inside the filter element 21 is extracted, and the air carrying dust outside the filter element 21 is filtered by the filter element 21 to filter the dust to the outside of the filter element 21. After working for a period of time, the air flow detector detects a low-pressure flow and issues an alarm. At this time, the air cavity inside the air storage tank 11 is full and in a compressed state. After the solenoid valve 14 receives the signal from the air flow detector, it opens the solenoid valve 14, so that the air is quickly dissipated from the air cavity to form an air impact force to clean the dust outside the filter element 21. The cycle works to ensure that the filter element 21 is always in the best condition, effectively increasing the service life of the filter element, reducing costs, ensuring that the road surface is cleaned, and reducing manual labor intensity.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
