Abstract

The utility model relates to a dust-separating mechanism for cyclone suction cleaner, which comprises a first cylinder[2] and a second cylinder[4]. The two ends of the first cylinder[2] are respectively provided with first end cover[3] and a second end cover[7] of the first cylinder[2]; the side wall of the first cylinder[2] is provided with a tangential inlet[1] and a dust outlet[12]; a filtering cylinder[10] is arranged on the second end cover[7] of the first cylinder[2]; the filtering cylinder[10] is positioned in a cyclone chamber[6]; a wind outlet channel tube wall[14] is also arranged on the second end cover[7] of the first cylinder[2]; the inner cavity of the wind outlet channel tube wall[14] is a wind outlet channel[15]. As the side wall of the filtering cylinder can filter the dust and allows the clean air to pass through, the total area of the whole filtering cylinder allowing the air current to pass through becomes big so that the centrifugal force the dust getting during the cyclone separating is comparatively big and the dust separating effect is good.

Description

The dust separation apparatus of rotoclone collector

Technical field

The utility model relates to the dust separation apparatus of a kind of dust catcher, particularly rotoclone collector.

Background technology

In the prior art, the dust separation apparatus of rotoclone collector comprises first cylindrical shell, second cylindrical shell, and the both ends of described first cylindrical shell are provided with first end cap of first cylindrical shell and second end cap of first cylindrical shell respectively; The side wall portion of first cylindrical shell is provided with tangential inlet, and this tangential inlet is near first end cap of described first cylindrical shell, and the side wall portion of described first cylindrical shell is provided with the dust mouth, and this dust mouth is near second end cap of described first cylindrical shell; The first end of described second cylindrical shell is connected with the side wall portion of described first cylindrical shell, and the inner chamber of described first cylindrical shell is a cyclone chamber, and the inner chamber of described second cylindrical shell is the dust pocket, and the dust pocket is connected by the dust mouth with cyclone chamber.Be fixed with the tubulose discharge pipe on first end cap of first cylindrical shell, this discharge pipe is connected with negative pressure source, and discharge pipe open-ended also is provided with screen pack.The air-flow that has dust enters from tangential inlet, dust enters the dust pocket from the dust mouth separation, and clean air enters negative pressure source from discharge pipe, because the port cross section of discharge pipe is little, screen pack is arranged again, therefore it is also less to enter the air quantity of discharge pipe from this port, makes that the cyclonic separation effect of air-flow in cyclone chamber is bad.

Summary of the invention

The purpose of this utility model is to provide a kind of dust separation apparatus of rotoclone collector of the air intake air quantity that can strengthen the air-out passage.

The technical solution of the utility model is: a kind of dust separation apparatus of rotoclone collector, comprise first cylindrical shell, second cylindrical shell, and the both ends of described first cylindrical shell are provided with first end cap of first cylindrical shell and second end cap of first cylindrical shell respectively; The side wall portion of first cylindrical shell is provided with tangential inlet, and this tangential inlet is near first end cap of described first cylindrical shell, and the side wall portion of described first cylindrical shell is provided with the dust mouth, and this dust mouth is near second end cap of described first cylindrical shell; The first end of described second cylindrical shell is connected with the side wall portion of described first cylindrical shell, the inner chamber of described first cylindrical shell is a cyclone chamber, the inner chamber of described second cylindrical shell is the dust pocket, the dust pocket is connected by the dust mouth with cyclone chamber, on second end cap of first cylindrical shell, be fixed with filtration barrel body, described filtration barrel body is positioned at cyclone chamber, be fixed with air-out passage tube wall on second end cap of described first cylindrical shell, the inner chamber of this air-out passage tube wall is the air-out passage, the filtration barrel body intracavity inter-connection of described air-out passage and described filtration barrel body.

The utility model compared with prior art has following advantage:

Because the sidewall of filtration barrel body can filter dust and allow pure air to pass through, so the gross area that the permission air communication of whole filtration barrel body is crossed becomes big, air-flow can more unimpededly enter into the filtration barrel body inner chamber, make that the dust centrifugal force that dust is subjected to when cyclonic separation is bigger, dust separation is effective.

The specific embodiment

Referring to accompanying drawing, a kind of dust separation apparatus of rotoclone collector comprises first cylindrical shell [2], second cylindrical shell [4], and the both ends of described first cylindrical shell [2] are provided with first end cap [3] of first cylindrical shell and second end cap [7] of first cylindrical shell respectively; The side wall portion of first cylindrical shell [2] is provided with tangential inlet [1], this tangential inlet [1] is near first end cap [3] of described first cylindrical shell, the side wall portion of described first cylindrical shell [2] is provided with dust mouth [12], and this dust mouth [12] are near second end cap [7] of described first cylindrical shell; The first end of described second cylindrical shell [9] is connected with the side wall portion of described first cylindrical shell [2], the inner chamber of described first cylindrical shell [2] is cyclone chamber [6], the inner chamber of described second cylindrical shell [4] is dust pocket [13], dust pocket [13] is connected by dust mouth [12] with cyclone chamber [6], on second end cap [7] of first cylindrical shell, be fixed with filtration barrel body [10], described filtration barrel body [10] is positioned at cyclone chamber [6], be fixed with air-out passage tube wall [14] on second end cap [7] of described first cylindrical shell, the inner chamber of this air-out passage tube wall [14] is air-out passage [15], and described air-out passage [15] is connected with the filtration barrel body inner chamber [11] of described filtration barrel body [10].

The sidewall of described filtration barrel body [10] is an accordion-like, shown in accompanying drawing 5 and accompanying drawing 3, can increase filter area, and the resistance that makes air communication cross is little.

The filtration barrel body end cap [5] of described filtration barrel body [10] is the end cap of sealing, because this end caps mainly is the air-flow that does not have dust-separating that has just entered cyclone chamber [6], so this end caps does not generally allow the air communication mistake.
