Description

Liquid distributor

Technical field

The utility model relates to the liquid distributor in a kind of fluid treatment appts, and especially relating to a kind of liquid collecting and cloth liquid is the liquid distributor of one.

Background technology

In the treating processes of waste liquid, need pending liquid is delivered in the fluid treatment appts.In the usually conduct device liquid-inlet pipe is set, is evenly equipped with a plurality of fluid holes on the liquid-inlet pipe, exterior line is delivered to pending liquid in the liquid-inlet pipe, by a plurality of fluid holes on the liquid-inlet pipe pending liquid is assigned in the treatment unit.But because the flow velocity of pending liquid and flow are extremely unstable, often cause, make pending liquid laying inhomogeneous, and influence the treatment effect of liquid in the liquid measure of the effusive liquid measure of liquid-inlet pipe anterior fluid hole institute greater than the rear portion fluid hole.For this reason, effect is set, discloses a kind of rotation water liquid device at present for improving liquid cloth liquid, constitute by motor, step-down gear, reducer pedestal, bearing in reduction gears seat, stuffing box, rotary valve etc., by the electric motor driving rotary valve,, make water distributing pipe be difficult for blocking with pending liquid uniformly distributing.But because rotary valve is mutual motion with respect to fluid treatment appts, complex structure not only, manufacturing cost and energy consumption height, and sealing is difficult for solving.

Technology contents

The purpose of this utility model provides a kind of simple in structure, reliable operation, the uniform liquid distributor of cloth liquid.

The utility model is that the technical scheme that achieves the above object is: a kind of liquid distributor, it is characterized in that: comprise that band outer tube, coaxial being arranged on dam ring in the outer tube in plural and be sealedly connected on interior pipe on the ring that dams in each, outer tube is provided with axial fluid notch, interior pipe is provided with the fluid hole reverse with the fluid notch, the rear end of outer tube and interior pipe is tightly connected by end socket, be sealedly connected with end cap between outer tube and the interior pipe front side, and in dam the ring internal diameter less than inner tube diameter.

Liquid distributor of the present utility model adopts the inner and outer pipe structure, pipe is communicated with external pipe in it, and interior pipe be provided with more than two change diameter of inner pipe in the ring that dams, make the liquid that enters in the interior pipe change the flow velocity of liquid by the interior ring back of damming, and by the fluid hole of interior pipe liquid is delivered in the outer tube, more evenly flow in fluid treatment appts from fluid notch again with the reverse outer tube of interior pipe fluid hole.Liquid distributor of the present utility model is fixedly mounted in the treatment unit, owing to there is not relative movement, not only be convenient to sealing, and interior pipe connects by the interior ring that dams and is arranged in the outer tube, simple in structure, manufacturing cost and use cost are low, because pending liquid enters the interior flow velocity and the pressure of managing the back and changing liquid under the effect of interior dam ring and outer tube, reach cloth liquid effect of uniform, reliable operation.The utility model also is provided with the outer ring that dams on the interior ring that dams, enter the interior liquid of outer tube by the ring that dams outward, can further change flow stream velocity, and further improve the homogeneity of cloth liquid.
