Description

Self-cleaning dust collector

Technical Field

The utility model relates to an automatically cleaning dust catcher in air purifier equipment field.

Background

The dust collector is a common cleaning tool, and the working principle of the dust collector is that a motor is used for driving blades to rotate at a high speed, air negative pressure is generated in a sealed shell to absorb the surfaces of objects such as carpets, floors, wall bodies and the like with dust, the dust is sucked into a dust-air separation component along with air, a filter is arranged in the dust-air separation component, dust gas is filtered by the filter, the dust is collected by a dust collection barrel, and the filtered clean air is discharged out of a dust collector body. During the dirt removing process of the dust collector, no matter the dust type filtration or the cyclone type filtration is carried out, dust is attached to the surface of the filter, and the longer the dust collecting device is used, the more the dust accumulated on the surface of the filter is, the ventilation performance of the filter is gradually weakened, the wind power is reduced, and therefore the dust removing performance of the dust collector is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a weak point that exists among the prior art, the utility model aims at providing a dust catcher with self-cleaning function makes the dust catcher also can blow off the dust that the filter surface accumulated when the dust absorption through set up self-cleaning device in the cartridge filter to solved the too fast problem of filter by the dust jam, made the filter can keep or resume enough big air permeability for a long time, and then better assurance dust catcher can keep stronger power.

The utility model discloses a realize through following technical scheme:

the utility model provides a self-cleaning dust collector, includes the host computer, strains a section of thick bamboo and fan, and the host computer is installed in the frame with straining a section of thick bamboo, and the fan is fixed in the host computer, its characterized in that: a cylindrical filter is arranged in the filter cylinder, a dust collecting barrel is arranged below the filter cylinder, a gas outlet is formed in a top cover of the filter cylinder, the gas outlet is communicated with an exhaust cavity in the host through a pipeline, a self-cleaning device is arranged in the filter cylinder and is positioned between the top cover of the filter cylinder and the cylindrical filter, the self-cleaning device is a pulse ash removal component, the pulse ash removal component is driven by an external gas source and is controlled by a pulse ash removal controller, dust air enters the filter cylinder through a suction inlet on the filter cylinder, is filtered by the filter in the filter cylinder, enters the exhaust cavity in the host through the gas outlet on the top cover of the filter cylinder, and; the technical scheme is further explained as follows: the pulse ash removal component comprises a compressed air inlet pipe, a nozzle and a Venturi tube, wherein the nozzle is arranged on the compressed air inlet pipe, the Venturi tube is arranged at the upper end of the cylindrical filter, the nozzle is arranged above an air inlet of the Venturi tube, and the compressed air inlet pipe is communicated with the high-pressure steam pocket through an isolation valve; the technical scheme is further explained as follows: the downstream filter is a high-efficiency activated carbon filter, and is used for purifying the filtered air at one time, so that the purification rate of the air is improved; the technical scheme is further explained as follows: the dust collecting barrel is a movable dust collecting barrel; the technical scheme is further explained as follows: a plurality of large-area cylindrical filters are arranged in the filter cylinder, and the effect of improving purification is achieved by improving the filtering area; the technical scheme is further explained as follows: the filter cartridge is provided with a negative pressure gauge for detecting the filter, and the condition of the filter is checked at any time.

Compared with the prior art the utility model has the characteristics of improve purification efficiency, make the filter can keep or resume enough big air permeability and better keep that the dust catcher has powerful suction for a long time.

Fig. 2 is a self-cleaning schematic diagram of the self-cleaning cleaner.

Figure 3 is an expanded view of the self-cleaning cleaner.

In the figure: the device comprises a main machine 1, a filter cartridge 2, a downstream filter 3, a dust collecting barrel 4, a filter cartridge cover 5, an air outlet 6, an air inlet 7, a pulse ash removal assembly 8, a fan 9, a high-pressure steam pocket 10, a Venturi tube 11, an isolation valve 12, a compressed air inlet pipe 13 and a nozzle 14.

Detailed Description

The invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the self-cleaning dust collector is a structure diagram and comprises a main machine 1, a filter cylinder 2, a downstream filter 3, a dust collecting barrel 4, a filter cylinder cover 5, an air outlet 6, a suction inlet 7, a pulse ash removal assembly 8, a fan 9, a high-pressure steam drum 10, a Venturi tube 11, an isolation valve 12, a compressed air inlet pipe 13 and a nozzle 14. The self-cleaning cleaner is an industrial cleaner that performs dust collection by a strong air current generated by a vacuum unit.
