Detailed Description

Referring to fig. 1 and 2, the present embodiment provides a double-layered cyclone dust collecting apparatus, which includes an upper cover 1, a filter element 2, an outer tub 3, a dust collecting tub 4, and an inner baffle 5.

An air inlet 31 is arranged on the lower part of the wall of the outer barrel 3, and an air inlet pipe 6 connected with the air inlet 31 is arranged on the outer wall of the outer barrel 3 for convenient connection.

The bottom center of the outer barrel 3 is provided with a dust outlet 32, the peripheral position of the dust outlet 32 is radially enlarged to form a mounting plate 33, and the dust collection barrel 4 is arranged on the mounting plate 33 through a hasp, so that the dust collection barrel 4 is sleeved on the dust outlet 32.

The inner baffle 5 is arranged in the outer barrel 3 corresponding to the inner side of the air inlet 31, and a dust exhaust channel 34 communicated with the dust outlet 32 is formed between the inner baffle 5 and the inner wall of the outer barrel 3,

the inner baffle 5 is bent and welded end to form a cylinder shape, the diameter of the upper end is larger, the diameter of the lower end is smaller, and the whole body is in an inverted cone shape. The upper edge of the inner baffle 5 is higher than the air inlet 31 and is connected to the inner wall of the outer barrel 3, and the lower edge of the inner baffle 5 extends downwards in an inclined manner until the lower edge is lower than the air inlet 31. A certain distance is reserved between the inner baffle 5 and the air inlet 31. When air with dust enters the outer barrel 3 through the air inlet 31, the area is increased and the speed is reduced, and then the air collides with the inner baffle 5, so that the dust and the air are separated into cyclone, a large amount of dust is directly separated without contacting the filter element 2, and then the dust is conveyed through the dust discharge channel 34 and discharged through the dust outlet 32. In other embodiments, the inner baffle 5 may also be bent in a circular arc shape or a right angle shape.

Preferably, the lower part of the outer barrel 3 is gradually reduced, which is more beneficial to collecting dust.

The filter element 2 is arranged in the outer barrel 3, and the upper cover 1 covers the opening on the top surface of the outer barrel 3 and is fixed through a hasp. The upper cover 1 can be conveniently detached, and convenience is brought to the replacement of the filter element 2. An air outlet is arranged at the center of the upper cover 1. In order to be conveniently connected with a vacuum source, an air outlet pipe 7 communicated with the air outlet is arranged on the upper surface of the upper cover 1.

For improving the filtering effect, a filtering cylinder 8 communicated with the air outlet is arranged on the lower surface of the upper cover 1, and the lower part of the filtering cylinder 8 is inserted into the filter element 2. The filter air cylinder 8 is cylindrical, and small holes with a filtering function are uniformly distributed on the surface of the filter air cylinder. The air after filtering through filter core 2 is filtered the back again through the aperture on the filter dryer 8 and is sent out, realizes dual filtration, further promotes the filter effect.

When the dust-carrying air enters the outer barrel 3 through the air inlet 31, the area is increased and the speed is reduced, and then the dust-carrying air collides with the inner baffle 5, so that a large amount of dust falls into the dust collection barrel 4 through the dust outlet 32, the air containing little dust is filtered through the filter element 2, and the filtered air is sent out to the vacuum source through the air outlet, thereby protecting the vacuum source, ensuring the normal work of the vacuum source, prolonging the service life and reducing the environmental pollution.
