Description
Technical field
The present invention relates to a kind of membrane module.
Background technology
Membrane module is usually used in membrane bioreactor, generally includes main frame body and the membrane tube being arranged on main frame body, to keep away
Exempt from dirt and be attached in membrane tube to cause membrane tube to block, membrane module would generally set aerator in the lower section of membrane module in use
Etc. being cleared up membrane tube and increase growth and breeding of the dissolved oxygen amount in water body in order to microorganism, wastewater treatment effect is improved
Rate.The top and bottom of existing its membrane tube of membrane module are each attached on main frame body and are bent into bifilar more, and membrane tube is relatively fixed,
It is only capable of being cleared up by aeration bubbles, and aeration bubbles easily spread, it is difficult to enter in the gap in the middle part of bifilar membrane tube so that
Sludge etc. easily deposits in the gap in the middle part of bifilar membrane tube so that membrane tube easily blocks, and influences the filter efficiency of membrane tube, another
Aspect, the bottom of membrane tube are generally fixed on the bottom of main frame body by modes such as bondings, and processing is more time-consuming, while main frame body
Bottom also can cause to block to the bottom of membrane tube so that the bottom that aeration bubbles are difficult to reach membrane tube is to be cleared up, in body frame
On body and the lower position of membrane tube easily alluvial sludge and cause membrane tube to block, can equally influence the filter efficiency of membrane tube.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide one kind be not easy to deposit sludge and impurity, be convenient to clean,
It is less prone to the curtain type film assembly with free end of blocking.
The present invention is for the technical scheme that uses of its technical problem of solution：
A kind of curtain type film assembly with free end, including main frame body and the soft membrane tube being arranged on main frame body, institute
State the top of membrane tube and main frame body is connected and membrane tube is suspended on main frame body, be provided with the main frame body horizontal spacing
Part, the bottom of the membrane tube have the limiting section being movably set on locating part, and the limiting section can move down on relative limit part
It is dynamic.
Preferably, described limiting section is in "U" shaped, and described locating part is located in the recess of limiting section and makes limiting section
It is movably set on locating part.
Preferably, described membrane tube bends to " U " font, and described limiting section is one section of membrane tube bottom.
Preferably, it is at a distance between the lower inwall of the limiting section and the lower outer wall of locating part and make limiting section can phase
Locating part is moved up and down.
Preferably, described locating part is in horizontal tubulose, is offered and its intracavity inter-connection on the outer wall of locating part
Solarization air cap, it is provided with locating part and its intracavity inter-connection and the air feed interface that can be connected with extraneous gas.
Preferably, there is the supply that is connected with the air feed interface and can be connected with extraneous source of the gas on described main frame body
Joint.
Preferably, there is liquid outlet channel, the open top of the membrane tube is located at the described liquid that goes out and led on described main frame body
It is connected in road by the inner chamber of membrane tube with the liquid outlet channel；On main frame body have connected with the liquid outlet channel and can with it is outer
The connection of boundary drain pipe road goes out liquid joint.
Preferably, the quantity of the membrane tube is some and is spaced apart along main frame body.
Preferably, described main frame body is in inverted " u " font, and described membrane tube is located in the recess of main frame body, described limit
Position part is arranged in the bottom opening of main frame body, and the both ends of locating part are separately fixed at the left side and right side of main frame body.
The beneficial effects of the invention are as follows：Because membrane tube is suspended on main frame body in the present invention, and there is activity in membrane tube
The limiting section being set on locating part, and limiting section can relative limit part move up and down, therefore exposed to this membrane module
Gas or when washing away, membrane tube can carry out swinging back and forth by a relatively large margin with respect to main frame body, and in the limit of locating part and limiting section
The sludge and impurity being attached in membrane tube can will not be effectively removed only towards a side oscillation under system, avoid sludge and impurity from depositing
And cause membrane tube to block, on the other hand because membrane tube is suspended on main frame body, the bottom of membrane tube is entered without setting on main frame body
The fixed crossbeam of row, therefore membrane tube will not be caused to block so that the hypomere of membrane tube also can be good with aeration bubbles or Wash flow
Good contact, can ensure that membrane tube is effectively cleared up, and avoid sludge and impurity from depositing, ensure the filter efficiency of membrane tube.
