Description

Automatic rotary dust removal device for dust removal equipment

Technical Field

The invention relates to a dust removing device, in particular to an automatic rotary dust removing device for the dust removing device.

Background

At present, many cotton processing enterprises or high-dust enterprises all dispose multilayer cylinder formula filter equipment, because the number of piles is many and the interval is little between every layer, this just leads to the dust on the clearance filter cloth difficult, and expends time, and the filter cloth is very easily blockked up the damage under the condition that can not get effective clearance, leads to equipment to shut down, expends manpower and materials extravagant.

The invention discloses a Chinese patent named as a cashmere soil impurity separating device, which can be used for adsorbing and recovering cashmere soil impurity separating device for fluff dust. The device comprises a dust removing room, wherein a group of cylindrical filter structures which are formed by filter paper and arranged in concentric circles are arranged in the dust removing room. One side of the filtering structure is provided with a dust collecting disc which can rotate around a central shaft and a corresponding dust collecting rod which is fixed on the dust collecting disc and inserted between the walls of the adjacent concentric cylinders, and the central shaft is provided with a dust collecting pipe. The dust absorption pipe absorbs dust and cashmere on the filtering structure through the suction on the rotary dust absorption disc, and then conveys the absorbed dust to the spiral conveyer through a pipeline for discharging. But the device can not recover the sucked cashmere; the whole disc-shaped dust collection disc covers the filtering structure, so that the flow of air flow in a dust collection room is influenced, and the dust collection efficiency and the excessive rate effect of the whole device are also influenced.

Detailed Description

The following are only embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention are intended to be covered by the scope of the present invention.

Fig. 1 to 3 show a preferred embodiment of the present invention. This embodiment provides a dust collecting equipment is with automatic dust collector that circles round. The device includes a filter. The filter is arranged in the box body 9 and is composed of N filter cylinders 10 which are arranged in a concentric circle. The wall of the filtering cylinder 10 is formed by a filter screen or filter cloth, and a gap is arranged between two adjacent filtering cylinders 10.

A hollow suction arm seat 2 which is connected with the rotating shaft 1 and can rotate along with the rotating shaft 1 is arranged on one side in the box body 9 of the filtering cylinder 10. And one end of the suction arm seat 2 opposite to the rotating shaft 1 is connected with an air inlet of a draught fan 5 outside the box body 9 through an induced draft pipe 6. The rotating shaft 1 is arranged at the center of the filtering cylinder 10 and is used for driving the suction arm seat 2 to rotate. The side wall of the suction arm seat 2 is connected with four hollow suction arms 3 which are mutually symmetrical and are positioned in the same plane. The suction arms 3 are sequentially provided with suction pipes 4 which are connected with M circular ventilation openings of the suction arms 3 and are inserted into gaps between adjacent filter cylinders 10 along the length direction; the frontal side wall of the suction pipe 4 close to the free end is provided with a long suction port 41 for sucking and cleaning dust and fiber adsorbed on the wall of the filtering cylinder 10. One side of the rotating shaft 1 outside the box body is connected with a horizontal rotation transmission device to the multi-lead screw. The single-rotation reciprocating lead screw transmission device drives the suction arm 3 to simultaneously perform rotary motion and linear reciprocating motion.

The suction opening 41 is formed in the side wall of the suction pipe close to the free end, and the length of the suction opening is 60 mm. The four drinking straws 4 located in the gaps between the same filtering cylinders 10 are different in length, and are sequentially different by 200 mm. The stroke of the rotary reciprocating lead screw is 200 mm. The width of the wall of the filtering cylinder 10 is 1000 mm.

And the air outlet of the induced draft fan 5 is connected with the cyclone separator 7 through an air pipe. The bottom outlet of the cyclone separator 7 is connected with a spiral discharging device, and the top outlet is connected with a secondary air pipe 8 communicated with a box body 9.
