Abstract

The utility model provides a wide channel detachable plate heat exchanger which exchanges heat for the mash and particle medium in various industries. In the utility model, a central area with herringbone ripples is formed; a plurality of supporting points are arranged at the converge of the herringbone ripples; the diversion area has a plurality of contact supporting points and an uneven guidance groove; and two sides of the sealing groove are wave-type reinforcing sheets, and the sealing cushion on the corner narrow channel side of the material is configured into double-ring structure. The structure not only increases the pressure capability of the sheets, increases the heat transfer coefficient, improves the heat transfer performance, balances the flow resistance, avoids the flowing dead end, overcomes the deficiency of the scale formation of the medium, increases the heat transfer efficiency, facilitates the cleaning and maintenance, and prolongs the service life. With novel design, compact and reasonable structure, the pipeline is convenient for connect; the sealing effect is good; and the performance is safe and reliable, which is suitable for the popularization in various industries.

Description

The removable plate type heat exchanger of fat pipe

Technical field: the utility model relates to a kind of board-like heat-exchange apparatus, particularly relates to the removable board-like heat-exchange apparatus of a kind of fat pipe.

Background technology: plate type heat exchanger is since development is come out, apart from modern existing more than 100 year history, because plate type heat exchanger has high efficient heat exchanging, is convenient to safeguard, obtained in a plurality of fields such as petrochemical industry, metallurgy, electric power, light industry, food, medicine, papermaking using widely.But in light industry, wine brewing, sugaring, textile and paper industry, relate to the heat exchange of handling mash, containing granule medium, adopted spiral heat exchanger or welded type broad passage plate heat exchanger to carry out heat exchange in the past through regular meeting.Though adopt described heat exchanger to carry out heat exchange to medium, exist disposablely have high input, heat transfer efficiency is low, easy fouling, service life short disadvantage.And the present domestic medium heat exchange demand that corresponding better equipment can satisfy this operating mode of still not having.Therefore, this problem is that the difficult problem that solves is thirsted in above-mentioned field for a long time always.

Summary of the invention: the utility model provides a kind of fat pipe removable plate type heat exchanger, mainly be to solve in light industry, wine brewing, sugaring, textile and paper industry, to mash, contain that disposable that the heat exchange of granule medium exists has high input, heat transfer efficiency is low, easy fouling and service life short problem.

Scheme of the present utility model is as described below: this utility model comprises by fixed head, portable plate, entablature, a sill and a framework that is configured to, the gasket seal that through between plate that fishbolt clamps and plate, is provided with between fixed head in framework and the portable plate, it is to be the herringbone ripple by a zone line is set, intersection is provided with a plurality of strong points at the herringbone ripple, Diverging area is for having a plurality of contact strong points and convex-concave guiding groove, and the sealed groove both sides are the plate of wave stiffened edge, and narrow passage side seal pad in material side angle hole are made as two circular ring structures realize.

This utility model is owing to taked said structure, especially the strong point, the setting of guiding groove and stiffened edge, make and constitute netted fulcrum in the passage that forms by plate, add organic cooperation of gasket seal, not only increased the bearing capacity of plate effectively, improved heat transfer coefficient, improved the heat transfer property of product, balance the flow resistance on the different runners, avoided flow dead, guaranteed the accurate location of gasket seal, overcome the easily stifled disadvantage of medium fouling, satisfied mash, contain the heat exchange demand of granule medium, improved heat exchange efficiency, make things convenient for the equipment clean and maintenance, prolonged the service life of equipment.And have novel uniqueness, compact conformation rationally, that pipeline connects is convenient, sealing effectiveness is all good, performance is safe and reliable, be fit in the row advantages such as popularization.

Fig. 1 is the overall structure schematic diagram of the removable plate type heat exchanger of fat pipe;

Fig. 2 is the sheet structure schematic diagram;

Fig. 3 is an A position partial enlarged drawing among Fig. 2;

Fig. 4 is a narrow passage side seal pad schematic diagram;

Fig. 5 is a width channel design form schematic diagram.

The specific embodiment: by the removable plate type heat exchanger of the described fat pipe of Fig. 1-Fig. 5 is to constitute framework of the present utility model by fixed head 1, portable plate 2, entablature 3, sill 4 and support 5, plate 6 is fixedly clamped it by fishbolt 8 between fixed head 1 and portable plate 2.Described plate 6 is the herringbone ripple, is provided with a plurality of strong points in herringbone ripple intersection 10 as the most basic heat transfer element zone line 9, its Diverging area 11 has a plurality of contact strong points and convex-concave guiding groove 12 and has constituted mosaic and divide streamedly, and is wave stiffened edge 14 in the both sides of sealed groove 13.And be pressed into plate 6 edges stepped.6 jiaos of holes of plate are hole, equal diameter angle, and are arranged to monolateral stream.When plate 6 is installed, should make a plate form the circulation passage of wide, narrow two kinds of different sizes with being inverted mutually between the two adjacent plates 6.And form clear distance between the plate of certain size in the fat pipe side, no matter fat pipe still is that the strong point of narrow passage plate ripple intersection supports mutually and forms a plurality of netted fulcrums.Sealed groove 13 at plate 6 is built-in with gasket seal 7.The structure of gasket seal 7 in fat pipe and narrow passage is different, and narrow passage side seal pad in material side angle hole is two circular ring structures.Mainly be to form the buildup dead band at this when avoiding the medium circulation.The mode that gasket seal 7 is taked to bond is fixed on the plate 6, several plates 6 that will be installed between fixed head 1 and the portable plate 2 by fishbolt 8 clamp with gasket seal 7,6 of adjacent plate have just formed the fluid flow passage, two kinds of cold and hot different fluids flow through in the passage of same plate both sides respectively, high temperature fluid passes through plate 6 with the heat transferred cryogen, thereby realizes the purpose of heat exchange.
