Description
Technical field
The utility model is related to a kind of Roots blower, especially a kind of wallboard bleeder Roots blower.
Background technology
With the development of industry, the special media purposes of Roots blower conveying than air is more and more extensive.Roots rouses
Wind turbine is mainly constructed such as Fig. 1, is equipped with wallboard 4 between casing 1 and main fuel tank 2, auxiliary fuel tank 3, in wallboard 4 equipped with sealing element and
The parts such as bearing block.It acts on one：It is as end cap, casing is closed at both ends, form an enclosed cylinder；Effect two：As
Bearing supports two ends of rotor.
Because rotor assembly 5 rotates, to avoid mutual collision friction between rotor assembly 5 and wallboard 4, between the two with micro-
Small―gap suture, therefore cause the leakage of pumped (conveying) medium.The medium of leakage can flow into major and minor fuel tank, if medium is unholiness biogas
When sulfur-containing mediums, the gear oil 10 in fuel tank can be polluted, destroy gear 11, cause security risk.
Utility model content
The technical assignment of the utility model be for the above-mentioned prior art in deficiency a kind of wallboard bleeder Roots is provided
There is gas leakage when solving Roots blower conveying special media to show for air blower, a kind of wallboard bleeder Roots blower
As.
Technical solution is used by the utility model solves its technical problem：It include casing, main fuel tank, auxiliary fuel tank,
Wallboard and rotor assembly, are respectively arranged with wallboard between the casing and main fuel tank, auxiliary fuel tank, it is total to be provided with rotor in wallboard
Into, the wallboard lower part between wallboard lower part, casing and auxiliary fuel tank between the casing and main fuel tank has connecting hole,
Wallboard lower part is connected between being taken over the air inlet on casing top by connecting tube.
The connecting tube is three-way pipe, and one end is taken over air inlet to be connected, and another both ends are each passed through wallboard lower part
Connecting hole is connected with wallboard inner cavity.
Blowdown valve is provided in the connecting tube, the blowdown valve includes two, is located at and wallboard connecting place respectively
Connecting tube on.
A diameter of 10-50mm of the connecting tube.
A diameter of 20mm of the connecting tube.
Compared to the prior art a kind of wallboard bleeder Roots blower of the utility model, has following prominent beneficial
Effect：The medium that would leak into wallboard is pumped into fan inlet again, prevents medium from entering fuel tank, and gear oil is polluted；It is close
Envelope effect is good, effectively avoids the leakage of conveying gas；Increase the safety of use site；Avoid the dirt of site environment
Dye；Simple in structure, production and processing is convenient；Flexible for installation, dismounting is easy to maintenance.

Specific embodiment
A kind of wallboard bleeder Roots blower of the utility model is made with reference to Figure of description 2 to attached drawing 4 following detailed
Carefully illustrate.
A kind of wallboard bleeder Roots blower of the utility model, structure include casing 1, main fuel tank 2, auxiliary fuel tank 3,
Wallboard 4 and rotor assembly 5 are respectively arranged with wallboard 4, are set in wallboard 4 between the casing 1 and main fuel tank 2, auxiliary fuel tank 3
There is rotor assembly 5, under the wallboard 4 between 4 lower part of wallboard, casing 1 and auxiliary fuel tank 3 between the casing 1 and main fuel tank 2
Portion has connecting hole 6, is connected between 4 lower part of wallboard and the air inlet take over 8 on 1 top of casing by connecting tube 7.
The connecting tube 7 is three-way pipe, and one end is connected with air inlet take over 8, and another both ends are each passed through 4 lower part of wallboard
Connecting hole 6 be connected with 4 inner cavity of wallboard.
Blowdown valve 9 is provided in the connecting tube 7, the blowdown valve 9 includes two, is located at and 4 phase of wallboard respectively
In connecting tube 7 at even.
A diameter of 10-50mm of the connecting tube 7.
A diameter of 20mm of the connecting tube 7.
A connecting hole 6 is processed below wallboard 4, connecting tube 7 is installed.By this connecting tube 7 by Roots blower into
Air port take over 8 connects with two wallboards 4, and after dielectric leakage is to wallboard 4, housing is pumped into again by connecting tube 7, defeated
It send to client's pipeline, so recycles, be effectively prevented the leakage of conveying gas.Blowdown valve 9 is installed in connecting tube 7 simultaneously, when
When conveying coal gas, because containing coal tar in coal gas, blowdown is concentrated using this blowdown valve 9.
Illustrative embodiments listed above are only not described to the utility model for understanding that the utility model is used
The restriction of technical solution, the those of ordinary skill in relation to field on the basis of technical solution described in claim, can also make
Go out a variety of variations or deformation, all equivalent variations or deformation should all cover the utility model claims it
It is interior.Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
