Description

Novel scale prevention plate type heat exchanger

Technical Field

The utility model relates to a heat exchanger technical field especially relates to novel scale control plate heat exchanger.

Background

At present, in the normal use process of a shield machine, most of power loss of a hydraulic and lubricating system is converted into heat in the pressure and mechanical energy conversion process, so that the temperature of oil is increased, the normal use of related machines can be seriously influenced after the temperature of the oil exceeds 60 ℃, the service life of hydraulic elements is shortened, and the maintenance cost of engineering machinery is increased.

At present adopt heat exchanger to cool down the processing to fluid usually in shield construction, because heat exchanger comprises many inlet tubes, the intraductal cooling water that leads to, take away the heat in the fluid through the cooling water, thereby make the cooling water temperature rise, form hot water outflow, at foretell cooling fluid's in-process, thereby can cause cooling water temperature to rise sharply and produce the incrustation scale, lead to the incrustation scale to solidify at the pipe inner wall, thereby serious influence heat exchanger's normal work, and can lead to heat exchanger's heat exchanger slab to damage when serious, thereby can't cool down to fluid, influence the normal operating of relevant machine.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model provides a novel scale control plate heat exchanger prevents to appear the phenomenon of incrustation scale in heat exchanger's the pipeline, and the effectual heat exchanger of mentioning among the prior art of having avoided easily appears the incrustation scale and leads to the problem of the unable normal work of heat exchanger.

The technical scheme of the utility model as follows:

a novel scale prevention plate type heat exchanger comprises a front end plate and a rear end plate, wherein a plurality of heat exchange plates are arranged between the front end plate and the rear end plate, a plurality of water pipes are inserted into the front end plate and reach the heat exchange plates close to the rear end plate, two water pipes of the front end plate and the rear end plate form a loop, so that a water inlet and a water outlet are formed, grooves are formed in the upper end and the lower end of each of the rear end plate and the heat exchange plates, an upper guide rod and a lower guide rod are inserted into the grooves in the upper end and the lower end, one ends of the upper guide rod and the lower guide rod, which are close to the front end plate, are fixed on the front end plate through bolts, one ends of the lower guide rod and the lower guide rod, which are far away from the front end plate, are fixed on a support column, a plurality of fastening rods are respectively inserted into the two sides of the front end plate, the water inlet of the water pipe is inserted with an ion rod of the ion rod water treatment device, so that the electronic structure in water molecules can be changed through the direct action of a high-voltage electrostatic field of the ion rod, the water dipoles surround anions and cations in the water and are orderly arranged in a chain shape according to the positive and negative sequence, the anions and the cations cannot move freely, the cations contained in the water cannot tend to the inner wall of the water pipe, and the calcium ions and the magnesium ions are prevented from forming scale on the inner wall of the water pipe, so that the scale prevention purpose is achieved.

And one ends of the lower guide rod and the lower guide rod, which are far away from the front end plate, are fixed on the support through bolts.

The utility model has the advantages that: the utility model discloses an insert the ion stick of ion stick water treatment ware at heat exchanger's water inlet for the effectual water pipe inner wall that has prevented forms the incrustation scale, has avoided appearing the incrustation scale on the heat exchanger and has leaded to the unable problem of normally working of heat exchanger.
