Abstract
The utility model provides a plate type heat exchanger, which comprises a heat exchange plate group and compacting plates on two sides of the heat exchange plate group, wherein the compacting plates on the two sides clamp the heat exchange plate group through clamping bolts; and each compacting plate is provided with a cold/hot medium access port, a connecting pipe is arranged in the cold/hot medium access port, the length of the connecting pipe is greater than the thickness of the compacting plate, a flange is arranged on one side of the connecting pipe, the other side of the connecting pipe is fixedly arranged on the inner wall of the cold/hot medium access port, and a nest is arranged in the connecting pipe. The plate type heat exchanger has the advantages that the plate type heat exchanger is simple in structure, convenient to connect, easy to machine, suitable for corrosive media and convenient to maintain.
Description
Technical field
A kind of plate type heat exchanger of the utility model comprises heat exchange plate group and the pressure strip that is positioned at said heat exchange plate group both sides, and the pressure strip of said both sides clamps said heat exchange plate group through fishbolt, and said pressure strip is provided with cold and hot medium and imports and exports.
Background technology
Plate type heat exchanger is the ideal equipment that liquid-liquid, liquid-vapour carry out heat exchange, has that heat exchange efficiency height, heat loss are little, characteristics such as advantages of compact and light structure, floor space are little, convenience for washing is installed, be widely used, long service life.Plate type heat exchanger comprises heat exchange plate group, fixed pressure plate, movable pressure plate, goes up lower guide rod and after-poppet, and one is assembled and be compacted into to fixed pressure plate and movable pressure plate through fishbolt with heat exchange plate group location.
When the plate type heat exchanger of prior art connects outer pipeline outside; Adopt dual mode: a kind of is outer pipeline through the external flange on it directly and the medium manhole appendix on the pressure strip docks and through on the screw that is bolted to pressure strip; Can overlap on the medium manhole appendix and be embedded with lining; But have following problem: 1, needs directly on clamping plate the flange standard according to external pipeline come processing screw hole, inconvenient installation; 2, because screw directly is processed on the pressure strip problem such as can take place in long-term use that bolt corrosion can't be pulled down or bolt breaks in screw;
Another kind is earlier carbon steel or stainless steel adapter to be sealed with the inboard welding of the medium manhole appendix of clamping plate; Take over the collar extension welded flange; Be connected with the external pipeline flange then, but have following problem: 1, taken over material and limit, be not suitable for corrosive cold and hot medium; When 2, taking over resistant materials such as adopting titanium, nickel, cost is high.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, conveniently connect, be easy to process, all be easy to the plate type heat exchanger changing and safeguard to different cold and hot media.
The technical scheme of the utility model is: a kind of plate type heat exchanger; Comprise heat exchange plate group and the pressure strip that is positioned at said heat exchange plate group both sides; The pressure strip of said both sides clamps said heat exchange plate group through fishbolt, and said pressure strip is provided with cold and hot medium and imports and exports, and said cold and hot medium is provided with adapter in importing and exporting; Said connecting pipe length is greater than the thickness of said pressure strip; Said adapter one side is provided with flange, and said adapter opposite side is packed on the inwall of said cold and hot medium import and export, and said adapter inboard is provided with nested.
Further, said adapter is welded on the said cold and hot medium import and export inwall.
Further, said nested two ends are respectively arranged with the protruding and interior annular convexity of exterior annular.
Further, said interior annular inwall protruding and said pressure strip contacts, and said exterior annular outer wall protruding and said flange contacts.
Further, the material of said adapter is carbon steel or stainless steel.
Further, said nested material is rubber or titanium or nickel.
Advantage and the good effect that the utlity model has are:
1, adopt long nested interface, on interface, be welded with flange, the hole on the flange is easy to processing, conveniently is connected with external pipeline;
2, the interface material is carbon steel or stainless steel, and is with low cost;
3, to different cold and hot media, can adopt different nestedly, make Korrosionsmedium can get into heat exchanger reliably and carry out heat exchange, enlarged the range of application of heat exchanger;
4, the problem of having avoided pressure strip screw inefficacy bolt to fracture, it is more convenient that part is changed in maintaining, cleaning.

The specific embodiment
As shown in Figure 1; The utility model comprises heat exchange plate group 3 and fixed pressure plate that is positioned at said heat exchange plate group 3 both sides 1 and movable pressure plate 2, and said fixed pressure plate 1 clamps said heat exchange plate group 3 with said movable pressure plate 2 through fishbolt 4, and said fixed pressure plate 1 is provided with cold and hot medium and imports and exports 5; Said cold and hot medium is imported and exported to be provided with in 5 and is taken over 6; Said adapter 6 length are greater than the thickness of said fixed pressure plate 1, and said adapter 6 one sides are provided with flange 7, and said adapter 6 opposite sides are packed on the inwall of said cold and hot medium import and export 5; Said adapter 6 inboards are provided with nested 8; Said nested 8 material can be selected different nested according to the difference of importing and exporting 5 media through cold and hot medium, can be chosen as rubber like generic media, can be chosen as titanium or nickel etc. like strong corrosive media.
As shown in Figure 2; Said nested 8 two ends are respectively arranged with exterior annular protruding 9 and interior annular convexity 10, and the left side wall of said interior annular protruding 10 and the right side wall of said fixed pressure plate 1 contact, and are convenient to when mounted nested 8 right sides clamped through fixed pressure plate 1 and heat exchange plate group 3; Form sealing; The right side wall of said exterior annular protruding 9 and the left side wall of said flange 7 contact, and are convenient to pass on left external water pipe and flange 7 clampings with nested 8 when mounted, form sealing.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
