Description
One, technical field
The utility model belongs to moisture film generating device technical field, and in particular to it is wet that one kind is suitable for gas drainage under suction equipment-
The moisture film generator of formula Roots vaccum pump.
Two, background technique
China's major part coal mine coal-bed gas pressure is big, gas bearing capacity is high, coal quality is soft, gas permeability is low, is not easy before adopting
Extraction.And the extraction in recovery process, Methane Diffusion fast speed, Yi Fasheng coal and gas prominent phenomenon, and it is quick-fried to induce gas
It is fried.Coal working face is modernized since mining rate is big, high-efficient, face Gas speed is adopted and is also increased sharply, often result in back
Upper corner (triangulation point) gas exceeding limit forms security risk on distinguished and admirable or working face, influences Homes Using TV.Establish ground low pressure extraction
System pump drainage goaf gas can solve the above problem, but such mode cost is higher.And utilize underground moving gas pump station
Extraction gas at upper corner is that down-hole treatment local gas gathers common method, but volume is big, low efficiency.In order to solve above-mentioned ask
Topic, is developed wet type Roots vaccum pump, which is capable of upper corner on the extraction coal mine return air stream or working face of big flow
(triangulation point) gas, guarantee Safety of Coal Mine Production, make working face it is distinguished and admirable in (air inlet, return air, upper corner, tail lane) gas density
It does not transfinite.But the equipment is in use, and there are following deficiencies: 1, run engineering in, between the running gear of the pump housing and its
Between internal chamber wall, gap very little has operational safety problem (contact and collision)；2, which is easy to appear poorly sealed existing
As there is extraction explosion hazard gases leakage problem.
Three, summary of the invention
The purpose of the utility model is to provide a kind of simple structure and reasonable designs, can effectively avoid wet type Roots vaccum pump
Occurs the moisture film generator of operational safety and extraction explosion hazard gases leakage problem when operation.
To achieve the above object, the technical solution adopted in the utility model are as follows: the generator includes that upper and lower part is equipped with respectively
The basin shape connection frame of upper and lower flange, its main feature is that: ring pipe is connected in the middle part of the basin shape connection frame；It is uniformly distributed on the inside of the ring pipe
There are multiple membranization nozzles, one side is connect with water inlet component one end, and the other end of water inlet component connects with water inlet pipe.
In use, the lower flange of the utility model is connected on wet type Roots vacuum pump steam inlet, upper flange is connected to
It conveys on gas piping, and moisture film water is passed through into ring pipe through water inlet component by water inlet pipe, the membranization nozzle on ring pipe
Moisture film water is atomized into the droplet that diffusivity is distributed and has certain adhesive force, is sucked by wet type sieve vacuum thatch pump intake negative pressure,
It is equably wrapped in internal chamber wall and running gear surface, makes the micro gap between running gear and its between internal chamber wall by water
Film is full of, and makes to be in contact and collide between them, realizes contactless high rotation speed operation, fundamentally solves operation peace
Full problem, and then ensure that the safe operation of wet type sieve vacuum thatch pump.Simultaneously as gap table between pump housing inner cavity, running element
Face is full of by moisture film, enhances sealing function, solves extraction explosion hazard gases leakage problem.The utility model structure is simple, sets
Meter rationally, ensure that wet type Roots vaccum pump safety, hermetically run, filled up the blank of such device, should be widely promoted
Using.

Five, specific embodiment
As shown, the utility model includes the basin shape connection frame 5 that upper and lower part is equipped with upper and lower flange 5-1,5-2 respectively.
Ring pipe 4 is connected in the middle part of the basin shape connection frame 5.Multiple membranization nozzles 3 are evenly equipped on the inside of the ring pipe 4.4 side of ring pipe with
The connection of 1 one end of water inlet component, the other end of water inlet component 1 connect with water inlet pipe.The water inlet component 1 by water pipe 1-1 and its
On pressure gauge 1-2 composition, both ends are connect with water inlet pipe and ring pipe 4 respectively by flange 2 and bolt 6.The membranization
Nozzle 3 includes nozzle body 3-5, and horn-like entrance 3-1 and outlet section 3-3 are equipped in nozzle body 3-5, they thick
Towards outside, thin mouth end is connected by linkage section 3-2 at mouth end, and outlet section 3-3 inner wall is equipped with spiral guide groove 3-4.Using
Above structure, the high-speed annular water flow in ring pipe 4, in the entrance 3-1 and linkage section 3-2 for flowing through membranization nozzle 3, due to
Latus rectum sharply becomes smaller, to generate instantaneous pressure effect, accelerates water flow rapidly, forms high velocity stream.High velocity stream passes through membranization
It, will due to the horn mouth release action of outlet section 3-3 and the guide functions of spiral guide groove 3-4 when the outlet section 3-3 of nozzle 3
High velocity stream is separated into countless small water droplets, forms umbrella cover shape and ejects, and then forms uniform atomized water.
The utility model also has a characteristic that
1, the good plate profile standard component of national standard is selected；
2, it after the completion of integral structure component manufacture, suppresses and does inspection of hermetic seal；
3, membranization nozzle, ring pipe select stainless steel material；
