Plate type heat exchanger is a kind of heat exchanger, is mainly applied to the every field such as petrochemical industry, marine equipment, power station.The structure of plate type heat exchanger comprises that fixed head, pressure strip, top guide bar, lower guide rod form; Between fixed head and pressure strip, operated by rotary motion has polylith heat exchange plate.Heat exchange plate compresses each other by hydraulic pressure or mechanical clamping device, and the heat exchanging fluid passage that adjacent plate forms of flowing through carries out exchange heat.Plate is heat exchange element, and generally the pressing metal plates by 0.5-0.7 millimeter is shaped, and posts sealing ring on plate, and the design of sealing ring is in order to control fluid flow direction in spaced-apart flow passages between plate.Guide rod plays location and guide effect, and the upper/lower terminal of each plate is provided with dovetail groove, and plate is suspended between upper and lower guide rail by dovetail groove, and can slide along guide rail.On every plate due to plate type heat exchanger, have a seal washer, seal perimeter is very long, sealing system poor rigidity, and structure is special, and the isolation of various heat exchange fluid is all to realize by sealing ring.When a plurality of plates are during in sheet and the stacked arrangement of sheet, between adjacent plate, easily there is mutual displacement, cause the voltage endurance capability of plate type heat exchanger not high, cause heat exchange efficiency not reach desirable requirement, even cause leakage.
Summary of the invention
The invention provides a kind of plate positioner of plate type heat exchanger, the plate that has solved existing plate type heat exchanger is located the inaccurate not high problem of voltage endurance capability that easily causes plate type heat exchanger in installation.
The present invention solves above technical problem by the following technical programs:
A kind of plate positioner of plate type heat exchanger, comprise front pressure strip and back prop, between the top of front pressure strip and the top of back prop, be provided with top guide bar, between the bottom of front pressure strip and the bottom of back prop, be provided with lower guide rod, pressure strip after being provided with between front pressure strip and back prop, between front pressure strip and rear pressure strip, be provided with heat exchanger fin, in the top middle portion of heat exchanger fin, be provided with dovetail groove, center bottom at heat exchanger fin is provided with lower dovetail groove, on the bottom face of top guide bar, be connected with the upper rail that cross section is isosceles trapezoid, on the top end face of lower guide rod, be connected with the lower guideway that cross section is square shape, cross section is that the upper rail of isosceles trapezoid is movably arranged in the upper dovetail groove that the top middle portion of heat exchanger fin arranges, the left locating latch side of upper dovetail groove coordinates with the trapezoidal left waist side of upper rail is movable, the right locating latch side of upper dovetail groove coordinates with the trapezoidal right waist side of upper rail is movable, the trapezoidal bottom surface of the lower camber side of upper dovetail groove and upper rail is tangent, lower guideway is movably arranged in lower dovetail groove, the movable cooperation of left surface of the lower guideway that the left location facade of lower dovetail groove is square shape with cross section, the movable cooperation of right flank of the lower guideway that the right location facade of lower dovetail groove is square shape with cross section.
Cross section is that the upper bottom surface of the upper rail of isosceles trapezoid is that the bottom surface of the lower guideway that cross section is square shape is to weld together with the top end face of lower guide rod together with being bolted with the bottom face of top guide bar.
The present invention is simple in structure, easy to assembly, has solved plate and has clamped and do not have location structure to cause producing mutual displacement in assembling, even causes the defect of leakage.And follow-up maintenance easy operating, convenient and swift, can save a large amount of maintenance times, all applicable to all model plate-type heat exchanger slabs, range of application is wider.
