Abstract

The utility model discloses a turnover bottom-delivery type ring-shaped dust-collecting cover, which comprises a dust-collecting cover body, wherein the duct-collecting cover body is provided with an open ring-shaped body of an inner ring groove, an integrated dust-collecting port is arranged on the inner ring groove wall with the open ring-shaped body, baffles which are used to space into a plurality of communicating cavities and dust-collecting channels are arranged in the inner ring groove along the tangential direction, and an induced draft connector which is communicated with the inner ring groove is arranged on the outer side of the open ring-shaped body along the tangential direction. The utility model completely purifies the field operation environment through the open ring-shaped body and the baffles which are arranged in the inner ring groove as negative dust-collecting cavity bodies to form cyclone dust-collecting channels, and provides reliable guarantee for the health of operators, simultaneously can realize the all-around dust-collecting effect as the dust-colleting cover can integrally turn over along with a fusion casting furnace.

Description

Upset lower-discharging type annular dust collection cover

Technical field

The utility model relates to a kind of upset lower-discharging type annular dust collection cover that is used for casting furnace, can control the diffusion of dust effectively.

Background technology

Administering environment is current focus problem, and particularly for numerous founding industries, majority does not have environmental protection udst separation facility.Because of the dust that in founding and refining process, produces, mainly be based on potassium fluotitanate and salt, flue gas contains pernicious gases such as hydrogen chloride, fluoride.For this reason, some founding industry adopted above the casting furnace fixing on row's formula dust collection cover, its structure is a cone cover, has a dust-exhausting port to be connected with the induced duct of vertical fixing at the top of cone cover.In actual applications, this cone cover is by the upper space of induced duct hanging casting furnace, and on the one hand, the observation sight line that directly has influence on the operator causes obstacle, influences casting quality; On the other hand, because space at regular intervals between cone-shaped hood and the founding fire door makes its pollutant discharge via operator's respiratory region by spacing, had a strong impact on operator's health and to the pollution of working environment.Therefore, seek a kind of technology that can effectively improve dust collection effect and become the problem that this area presses for solution.

Summary of the invention

In view of the situation of above-mentioned prior art, the utility model provides a kind of upset lower-discharging type annular dust collection cover, and it has by the dust collection cover that can form the eddy flow state and is installed on the casting furnace purpose that makes it reach comprehensive dust collection effect and reduce environmental pollution.

For achieving the above object, the utility model provides a kind of upset lower-discharging type annular dust collection cover, comprises the cover body that gathers dust, and the wherein said cover body that gathers dust has the open annular of an inner groove; Have gathering dust mouthful of an integral body and be positioned at inner groove at the inner groove wall of described open annular and be laid with the deflector that is partitioned into some connected chambers and gathers dust passage by tangential direction side; Induced duct joint with the inner groove conducting tangentially is set in the described open annular outside.Because the dust collection cover integral installation is on the founding fire door, and can connect upset thereupon by flexible pipe, because the fairing air quantity resistanceless motion of annular solid, Pei Zhi deflector can make gas produce swirling flow in addition, avoid the diffusion of dust, realized omnibearing dust collection effect.

According to scheme of the present utility model, the cross section of related open annular is round, cuboid, gengon or " U " body.Help dusty gas like this by forming negative pressure in mouthful open annular that enters into various cross sections body of gathering dust, discharge by air-introduced machine.In addition, can come selected shape according to the type of furnace, dust situation, site environment.

According to scheme of the present utility model, the related deflector that is arranged in the inner groove is vertical body or camber line body or a curved body.Therefore by negative pressure, the cavity that dusty gas is partitioned into along deflector and the passage that gathers dust of conducting are discharged through the flexible pipe that the induced duct joint connects.

In a word, the utility model provides a kind of upset lower-discharging type annular dust collection cover that can be installed on intermediate frequency, the power frequency founding fire door, form the dust swirling flow passage that gathers dust by the deflector that disposes in the open annular that has and the inner groove thereof as the negative pressure cavity that gathers dust, thoroughly purified the execute-in-place environment, for operator's health provides reliable assurance; This dust collection cover can have been avoided the dust diffusion with the whole upset of casting furnace simultaneously, has realized omnibearing dust collection effect.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the upward view of Fig. 1.

Fig. 3, Fig. 4 are another embodiment views of Fig. 1 deflector.

Fig. 5, Fig. 6, Fig. 7, Fig. 8 are the different embodiment schematic diagrames of Fig. 1 open annular.

The specific embodiment

Below in conjunction with accompanying drawing embodiment, the utility model will be further described, and the accompanying drawing of giving only is to be used for reference and explanation usefulness, is not to be used to limit the utility model scope.

By Fig. 1, upset lower-discharging type shown in Figure 2 annular dust collection cover, comprise the cover body that gathers dust that open annular 1 that a cross section is a round forms; The mouth 2 that gathers dust that the internal ring wall of described open annular 1 has an integral body makes the cover body that gathers dust constitute an inner groove.In described inner groove, be distributed with the deflector 3 that is partitioned into some conductings chamber by tangential direction; Be provided with six in the present embodiment at an angle perpendicular to the deflector 3 of inner groove.This deflector 3 wherein leaves the passage 5 that gathers dust of mutual conduction between the external annulus of an end and inner groove.When forming negative pressure in the cover body that gathers dust, make dust that casting furnace produces mouthfuls 2 be drawn into and form swirling flow in the some cavitys that are partitioned into by deflector 3 and draw via the passage 5 that gathers dust by gathering dust; Outdoor in order to guarantee that dust enters, and the tangential direction in described open annular 1 outside is provided with one and is connected with the flexible pipe of introducing the mistress with the induced duct joint 4 of inner groove conducting.During application, this cover body that gathers dust is installed in founding fire door upper end, and can overturn thereupon, has realized omnibearing dust collection effect.

Fig. 3 has provided the embodiment different with Fig. 1 deflector 3.Described deflector 13 is arc bodies.Its mounting means is identical with Fig. 1 to be by the tangential direction setting.

Fig. 4 has provided the embodiment different with Fig. 3 deflector 13.Described deflector 23 is curved bodies that form along its length.Its mounting means is same as described above.

Fig. 5, Fig. 6, Fig. 7, Fig. 8 have provided the embodiment of open annular 1 several different cross section shapes, the described formation mouth that gathers dust that the common-base body of cover body is open annular and has that gathers dust; Different is:

The cross section of the open annular 11 of Fig. 5 is a cuboid; Has the swirling flow that dust is formed equally.

The cross section of the open annular 21 of Fig. 6 is " U " body.

The cross section of the open annular 31 of Fig. 7 is a gengon.

It is to have done corresponding improvement on Fig. 1 architecture basics for Fig. 8, and promptly having adopted identical cross section is the open annular 41 of a round; Different is gathers dust mouthful and to sink down into one section cambered surface opening to the parallel surface at the ring end down by last ring portion.
