Abstract

A cyclone deduster is composed of external cyclone barrel body containing internal barrel with filter layer, deduster casing and airflow channel, and features that an ash stop plate with cyclone air inlet is arranged at open end of the said external cyclone barrel. It can prevent ash dust from coming into the cyclone air inlet and the spiral cyclone air inlet on the ash stop plate can benefit the separation of ash dust from air.

Description

Rotoclone collector

The present invention relates to a kind of rotoclone collector.

In the prior art, Britain Notetry Ltd took the lead in developing the dust-separating appliance that utilizes the centrifugal mechanism of swirling eddy in 1996, it is based on a common physical principle: make object make circular motion with certain acceleration (a), the external force (F) that adds thereon is directly proportional with its quality (m), i.e. F=ma; After external force did not exist, object tendency to drift away in the high speed rotary course that quality is big was also big.Therefore, if make the air-flow that has dust with certain rotating at a high speed, then dust granule can be separated greater than air quality because of its quality.Rotoclone collector comprise end sealing whirlwind outer cylinder body, the Body case of cleaner that is connected with the openend of described whirlwind outer cylinder body, be arranged at and be used for the interface tube that air-flow imports, the air-flow bend that is connected with described interface tube on the described Body case of cleaner, be provided with coaxial inner barrel in the inner chamber of described whirlwind outer cylinder body, this inner barrel is provided with filter course, the inner chamber of described whirlwind outer cylinder body is used for the air outlet of air-flow output and the intracavity inter-connection of described inner barrel by the gap of filter course and the intracavity inter-connection of inner barrel; When this dust catcher was not worked and need to erect placement, the dust that is present between whirlwind outer cylinder body and the inner barrel just can be swung to air-flow bend place, made that cleaning whirlwind outer cylinder body is very inconvenient.

The object of the present invention is to provide and a kind ofly can when dust catcher is erect, block the rotoclone collector that dust is swung to the air-flow bend, is convenient to clean.

Technical scheme of the present invention is: a kind of rotoclone collector, the whirlwind outer cylinder body that comprises end sealing, the Body case of cleaner that is connected with the openend of described whirlwind outer cylinder body, be arranged at the interface tube that is used for the air-flow input on the described Body case of cleaner, the air-flow bend that is connected with described interface tube, be provided with coaxial inner barrel in the inner chamber of described whirlwind outer cylinder body, this inner barrel is provided with filter course, the inner chamber of described whirlwind outer cylinder body is used for the air outlet of air-flow output and the intracavity inter-connection of described inner barrel by the gap of filter course and the intracavity inter-connection of inner barrel; The open end of described whirlwind outer cylinder body is provided with the annular dust block board that radially extends, this dust block board has sealed the space between inner barrel and the whirlwind outer cylinder body, only on dust block board, have the whirlwind inlet of dust block board, the whirlwind inlet of described dust block board is the one section helical form coaxial with the axial line of whirlwind outer cylinder body, and described interface tube is connected with the air-flow rotating room of described whirlwind outer cylinder body inner chamber by the whirlwind inlet of described dust block board.

The present invention compared with prior art has following advantage:

Owing to be provided with dust block board, therefore can block dust and flow to the dust suction inlet, and the spirality whirlwind of opening on dust block board inlet can make air-flow advance with the hand of spiral in the inner chamber of Whirlwind barrel, it is separated from the gas to be convenient to dust.

The invention will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a surface structure rearview of the present invention;

Accompanying drawing 2 is the main cutaway view of cyclonic separation part of the present invention;

Accompanying drawing 3 is the A-A cutaway view of accompanying drawing 2;

Accompanying drawing 4 is the B-B cutaway view of accompanying drawing 2; Wherein:

[1], Body case of cleaner; [2], interface tube; [3], air-flow rotating room; [4], whirlwind outer cylinder body; [5], filter course; [6], inner barrel; [7], passage; [9], air-flow bend; [10], air outlet; [11], dust block board; [12], bend partition; [13], air flow inlet; [14], the whirlwind of dust block board inlet; [16], motor switch;

Embodiment: a kind of rotoclone collector, the whirlwind outer cylinder body [4] that comprises end sealing, the Body case of cleaner [1] that is connected with the openend of described whirlwind outer cylinder body [4], be arranged at the interface tube [2] that is used for the air-flow input on the described Body case of cleaner [1], the air-flow bend [9] that is connected with described interface tube [2], be provided with coaxial inner barrel [6] in the inner chamber of described whirlwind outer cylinder body [4], this inner barrel [6] is provided with filter course [5], the inner chamber of described whirlwind outer cylinder body [4] is used for the air outlet [10] of air-flow output and the intracavity inter-connection of described inner barrel [6] by the gap of filter course [5] and the intracavity inter-connection of inner barrel [6]; The open end of described whirlwind outer cylinder body [4] is provided with the annular dust block board [11] that radially extends, this dust block board [11] has sealed the space between inner barrel [6] and the whirlwind outer cylinder body [4], only on dust block board [11], have the whirlwind inlet [14] of dust block board, the whirlwind inlet [14] of described dust block board is the one section helical form coaxial with the axial line of whirlwind outer cylinder body [4], and described air-flow bend [9] is connected with the air-flow rotating room [3] of described whirlwind outer cylinder body [4] inner chamber by the whirlwind inlet [14] of described dust block board.The air-flow that has dust enters air-flow bend [9] from interface tube [2] through air flow inlet [13], locate air-flow at air-flow bend [9] and begin rotation, and screw in air-flow rotating room [3] from the whirlwind of dust block board inlet [14], dust and gas are separated herein, dust rotates at a high speed along the inwall of whirlwind outer cylinder body [4], air-flow then passes through filtering layer [5] and enters in the inner chamber of inner barrel [6], flows out from air outlet [10] to enter negative pressure source.

Described air-flow bend [9] inboard is bend partition [12], and described bend partition [12] is tangent with the outer wall of inner barrel [6] haply, and air-flow promptly begins rotation after in entering air-flow bend [9].Described dust block board [11] is stuck on the end face of described inner barrel [6], take off whirlwind outer cylinder body [4] and dust block board [11] after, dust is poured out from the inner chamber of whirlwind outer cylinder body [4].
