Abstract

The utility model discloses a spiral ligament device which can prevent a heat exchange pipe from being encrusted, comprising a rotating rod, a fixed frame, a spiral ligament and a connecting piece. The smaller end of the rotating rod is sleeved in a hole on an axial liquid inlet end of the fixed frame to form a rotation matching; the endpoint of the smaller end of the rotating rod is hinged with the endpoint of one end of the spiral ligament through the connecting piece; the cylindrical-end of the fixed frame can be connected with the heat exchange pipe. The utility model needs no additional driving force and does not consume much manpower and resources, but uses the self-flow of the fluid inside the heat exchange pipe to drive the spiral ligament for continuous rotation inside the heat exchange pipe to prevent scale on the inner wall of the exchange pipe so as to achieve the cleaning-free effect, avoid re-cleaning trouble, conserve energy and create economic benefits.

Description

Can prevent the spiral band device of heat exchanger tube fouling

The utility model relates to the cleaning device that uses self working fluid.

At present, the apparatus for eliminating sludge in shell and tube heat-exchange apparatus field has been adopted variety of way, as artificial bamboo bar bucket wash, giant flushing, mechanical reamer are bored and are washed, the chemicals pickling, even higher with cost, as to reclaim difficulty glueballs cleaning etc.But fouling again after these modes are not all broken away from and cleaned, the worry that must clean again again, and the drawback that in cleaning, all need change a large amount of human and material resources of expense, also cause service life of equipment to reduce.

The purpose of this utility model provides a kind of spiral band device that can prevent the heat exchanger tube fouling, and flowing by fluid drives the spiral band rotation, does not make in-tube fouling, reaches and exempts to clean antiscaling effect.

In order to achieve the above object, the technical solution adopted in the utility model is: it comprises dwang, fixed mount, spiral band, connector, the small end of dwang is inserted in to form in the hole of fixed mount shaft orientation liquid feeding end and is rotatably assorted, one end end points of the small end end points of dwang and spiral band is hinged with connector, and fixed mount cylindrical shape end can be connected with heat exchanger tube.

The useful effect that the utlity model has is: it need not additionaling power, do not take manpower, material resources, the helical band that self flow to drive by the heat exchanger tube inner fluid is not parked in and does not stop rotation in the heat exchanger tube continuously, stop the inside pipe wall fouling, play and exempt from cleaning performance, avoid cleaning again worry, can also energy savings, create economic benefit.

Below in conjunction with accompanying drawing, the utility model is described in detail.

Description of drawings:

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

Fig. 2 is the A-A cutaway view of the utility model Fig. 1.

As shown in Figure 1 and Figure 2, it comprises dwang 1, fixed mount 2, spiral band 3, connector 5; The small end of dwang 1 is inserted in to form in the hole of fixed mount 2 shaft orientation liquid feeding ends and is rotatably assorted, and an end end points of the small end end points of dwang 1 and spiral band 3 is hinged with connector 5, and fixed mount 2 cylindrical shape ends can be connected with heat exchanger tube 4.The radial dimension of spiral band 3 is slightly less than the internal diameter of heat exchanger tube 4, and the length of spiral band 3 and heat exchanger tube 4 are isometric.Connector 5 is stainless steel wire rings.

When feed liquor in the heat exchanger tube and when reaching certain flow rate, spiral band 3 does not stop rotation together with connector 5 and dwang 1, destroys detention layers in original heat exchanger tube 4, and with the constantly slight scraping of tube wall, stop in-tube fouling.Owing to do not need exterior power, reach and exempt from cleaning performance.

Dwang 1, fixed mount 2, spiral band 3 are all made with high temperature resistant, corrosion-resistant, wear-resistant, age inhibiting macromolecular material, once are installed in the heat exchanger tube, can use continuously more than 5 years.
