Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
as shown in Figure 1, in embodiments of the invention, a kind of filter cartridge type dust removal machine, it comprises casing 1, mount pad 3, filter, deashing device 2.
casing 1 is the agent structure of this filter cartridge type dust removal machine.Casing 1, substantially in cuboid, is hollow structure in it.Offer air intake vent 11 in the bottom of casing 1, offer air outlet 12 on the top of casing 1.The gas treating dedusting is passed in the air intake vent 11 of casing 1.Treat that the gas of dedusting enters in casing 1 from air intake vent 11, by deriving casing 1 from air outlet 12 after filtration devices.Casing 1 is provided with safety door, and operating personnel change filter by opening safety door.
mount pad 3 is fixedly installed in casing 1.Mount pad 3 is positioned at middle and upper part or the middle part of casing 1 substantially, and mount pad 3 must form enclosure space with the middle and lower part of casing 1 or bottom could form pure dedusting environment.
mount pad 3 can arrange multiple filter.
each filter comprises core pipe 5, Venturi tube 4, filter cylinder 7, lower shrouding 6.
the long axis direction of core pipe 5 parallels with vertical direction.And the long axis direction of mount pad 3 extends in the horizontal direction.Adopt this kind of structure, the volume of the casing 1 in the present invention becomes minimum, and structure is optimized the most.Preferably, the upper end of core pipe 5 has protuberance upward, and this protuberance is tapered, can form water conservancy diversion thus to improve filter efficiency.
top and the Venturi tube 4 of core pipe 5 fix setting.Venturi tube 4 can accelerate compressed-air actuated flowing velocity, improves cleaning efficiency.Deashing device 2 is blown into compressed air from the upper opening end of described Venturi tube 4 in filter cylinder 7.Bottom and the lower shrouding 6 of core pipe 5 are fixedly connected.Concrete, the bottom of core pipe 5 can adopt screw thread to be connected with between lower shrouding 6.Filter cylinder 7 is set on core pipe 5, and forms a cavity between the outer wall of the inwall of filter cylinder 7 and core pipe 5.
as shown in Figure 2, Venturi tube 4 is plugged on mount pad 3.Venturi tube 4 comprises body 41 and is positioned at the projection 42 of body 41 external margin.As shown in Figure 3, specifically, Venturi tube 4 is cylindrical, and multiple protruding 42 arrange along the circumferencial direction of the cross section of Venturi tube 4, described mount pad 3 offers the first hole 32 vertically extended and the second hole 31 be connected with the first hole 32; During described protruding 42 described second hole 31 of insertion, described Venturi tube 4 fixes with described mount pad 3; Described protruding 42 with described second hole 31 be separated and enter described first hole 32 time, described Venturi tube 4 can be mounted opposite seat 3 and vertically slide.
the upper end of filter cylinder 7 offsets with the lower end of protruding 42.Lower end and the lower shrouding 6 of filter cylinder 7 offset.Such dedusting gas would not be gone out from the gap leakage between filter cylinder 7 and protruding 42.
preferably, protruding 42 comprise the insertion mount pad 3 vertically extended insertion section and dorsad Venturi tube extend push against portion, upper end and the described bottom pushing against portion of filter cylinder 7 offset.Adopt this kind of structure, filter cylinder 7 increases with the contact area of projection 42, thus adds the sealing between filter cylinder 7 and Venturi tube 4.
installation method of the present invention is be plugged on mount pad 3 by the Venturi tube 4 with core pipe 5, and is set in outside core pipe 5 by filter cylinder 7, is then offseted the bottom of filter cylinder 7 with the projection 42 of Venturi tube 4 by lower shrouding 6, is finally fixed with core pipe 5 by lower shrouding 6.Method for dismounting of the present invention is removed from core pipe 5 by lower shrouding 6, is shifted out by filter cylinder 7, the Venturi tube 4 with core pipe 5 is completed dismounting after mount pad 3 removes, and can change filter cylinder 7 thus from core pipe 5.
preferably, between Venturi tube 4 and described core pipe 5, be provided with deflector 8, while connection Venturi tube 4 with core pipe 5, the flow direction of dusty gas can also be changed to reach better dust removing effects.
preferably, the filter of an employing activated carbon filtration is provided with in the exit of described casing 1.Active carbon can be removed the noxious material in dusty gas.
above specific embodiment of the present invention is illustrated in conjunction with diagram, clearly on the basis not leaving scope and spirit of the present invention, much can revise prior art and technique.In art of the present invention, the usual knowledge of a GPRS, just within the scope of technology main idea of the present invention, can carry out diversified change.
