Abstract

The utility model provides a Roots blower easy for pollution discharge, comprising a casing, a rotor and a pollution discharging system, wherein the pollution discharging system comprises a pollution discharging pipe and a gas sealing pool; the bottom of the casing is provided with a pollution guiding groove and a pollution discharging port, and the pollution discharging port is communicated with the pollution guiding groove; the gas sealing pool is a deep water pool; and one end of the pollution discharging pipe is connected with the pollution discharging port at the bottom of the casing, and the other end of the pollution discharging pipe is inserted into the gas sealing pool. The Roots blower easy for pollution discharge has the advantages of simple structure, good pollution discharging effect and easiness for maintenance and cleaning, so that the blower runs stably, reliably, therefore, the Roots blower easy for pollution discharge is especially suitable for conveying gas containing a certain amount of special impurities (such as coal tar and the like) in gas medium.

Description

A kind of Roots blower of easy blowdown

Technical field

The utility model belongs to the Roots blower of blower fan technical field, particularly a kind of easy blowdown.

Background technique

For the Roots blower that contains a certain amount of special impurities (as the coal tar wet goods) in the gas medium of carrying; no problem when moving at the beginning; after operation a period of time; when blower cavity inner product has certain impurity; though can also proper functioning in when operation, in case shut down, impurity such as a large amount of tar can be sticked together impeller and cavity and can't start once more; often need in cavity, to inject a large amount of cleaning solutions and clean, very trouble.Cost is higher.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, filth-discharging effect good, be easy to the Roots blower of the easy blowdown of maintenance clean.

For achieving the above object, the technical solution adopted in the utility model is a kind of Roots blower of easy blowdown, comprise casing and rotor, its innovative point is: also comprise drainage, described drainage comprises drain pipe and envelope gas pond, and dirt guiding groove that described bottom of shell is provided with and sewage draining exit, sewage draining exit communicate with dirt guiding groove, and envelope gas pond is a swimmer's pool, drain pipe one end links to each other with the sewage draining exit of bottom of shell, and the other end inserts in the envelope gas pond.

Described sewage draining exit is positioned at the neutral position of bottom of shell, and respectively there is a dirt guiding groove on both sides, the bottom surface of dirt guiding groove by two ends all to sewage draining exit one end inclination β angle.

The cross section of described dirt guiding groove is rectangle, semicircular arc or triangle.

The degree of depth 〉=the 1m in described envelope gas pond.

Described drain pipe is provided with blowdown valve.

The bottom in described envelope gas pond is provided with liquid-discharging tube and liquid discharging valve.

After adopting technique scheme, owing to processed a sewage draining exit in the fan casing bottom, this sewage draining exit links to each other with drainage, and the impurity of cumulative is excreted timely.It is too much to have solved the interior impurity of cavity, influences the problem that blower starts once more.

Described drainage mainly is made up of drain pipe and envelope gas pond, bottom of shell is provided with dirt guiding groove and sewage draining exit, drain pipe one end links to each other with the sewage draining exit of bottom of shell, the other end inserts in the envelope gas pond, blower fan is when conveying gas, an impurities part can be adsorbed on chassis chamber inner body surface and the impeller in the gas, can flow under the effect of gravity in the dirt guiding groove of bottom of shell, flows into envelope gas pond through sewage draining exit by drain pipe again.Envelope gas pond is a pond that certain depth is arranged, guarantee trash flow in the blower fan cavity go in the pond in and high pressure air in the chamber is known from experience and is sealed by the hydraulic pressure in the pond, can not leak.

Description of drawings

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

Fig. 2 is the structural representation that the utility model removes drainage.

Embodiment

The embodiment who provides below in conjunction with accompanying drawing describes in further detail a kind of easy blowdown Roots blower of the utility model.

Referring to Fig. 1,2, a kind of Roots blower of easy blowdown, comprise casing 1 and rotor 2, also comprise drainage 3, described drainage 3 comprises drain pipe 3-1 and envelope gas pond 3-2, and dirt guiding groove 1-1 and sewage draining exit 1-2, sewage draining exit 1-2 that described casing 1 bottom is provided with communicate with dirt guiding groove 1-1, and envelope gas pond 3-2 is a swimmer's pool, drain pipe 3-1 one end links to each other with the sewage draining exit 1-2 of casing 1 bottom, and the other end inserts among the envelope gas pond 3-2.

In order to improve filth-discharging effect, described sewage draining exit 1-2 is positioned at the neutral position of casing 1 bottom, and respectively there is a dirt guiding groove 1-1 on both sides, the bottom surface of dirt guiding groove 1-1 by two ends all to sewage draining exit 1-2 one end inclination β angle.Dirt guiding groove is high outside and low outside skewed slot shape, becomes inverted ladder-shaped, so that draw dirt.

The cross section of described dirt guiding groove 1-1 is rectangle, semicircular arc or triangle.

The degree of depth 〉=1m of described envelope gas pond 3-2.The degree of depth in envelope gas pond according to blower fan outlet boost and seal that density of liquid designs in the gas pond, sealed by the hydraulic pressure in the pond to guarantee the high pressure air physical efficiency in the blower fan.

Seal gas pond 3-2 cleaning for convenience, the bottom that described drain pipe 3-1 is provided with the described envelope gas pond 3-2 of blowdown valve 3-3 is provided with liquid-discharging tube 3-4 and liquid discharging valve 3-5.

Easy blowdown Roots blower of the present utility model has simple in structure, easy to process, the advantage that filth-discharging effect is good, be easy to maintenance clean, make blower stable, reliable, therefore be specially adapted to contain in the conveying gas medium gas of a certain amount of special impurities (as the coal tar wet goods).
