Abstract

The utility model provides a case like positioned welded plate type heat exchanger. The utility model is composed of a rectangular case (4), a positioned cross beam (5), a set of elliptical seal grooves, a heat exchanging sheeet pair (3), and a case cover (10), wherein, the elliptical seal grooves are positioned by the positioned cross beam (5) which is arranged by the rectangular case (4); one opposite angle of the elliptical seal grooves is a tangent angle, the periphery of a flow channel hole (1) which is arranged at the other opposite angle is provided with the elliptical seal grooves and the heat exchanging sheet pair (3) of an O-shaped seal ring (6); one positioned cross beam hole (2) is positioned in the elliptical seal grooves; the O-shaped seal ring (6) is arranged in the grooves; the inner side of the circumference of the case cover (10) is provided with a block (8), and the positioned cross beam (5); the extending end of the case cover (10) is provided with a seal cover (9); the case cover (10) is tightly pressed and sealed by a screw bolt (11). The utility model has the advantages that the structure is simple; the design is novel; the utility model can resist pressure, heat, and shocks; the utility model without leakage can not be deformed, and misplaced; the property of sealing is favorable, the efficiency of exchanging heat is high; the property is reliable; the assembly and disassembly are convenient, etc.

Description

But box tack welding fishplate bar sheet heat exchanger

The utility model relates to a kind of heat-exchanger rig, particularly relates to a kind of welded plate type heat-exchanger rig.

Existing common plate type heat exchanger mainly is the heat transferring plate that is pressed with ripple by the polylith that is stacked, and constitutes along sealing gasket that is provided with all around and outer clamping plate and the fishbolt of two ends heat transferring plate between each heat transferring plate.Along with continuous advancement in technology, have in recent years welding of two heat transferring plate peripheries or flanging are welded the plate of formation to replacing heat transferring plate, though can reduce the consumption of sealing gasket, prevent the sealing gasket hot mastication, leak, make withstand voltage heat-resisting index to obtain corresponding improvement and improve heat exchange efficiency, but effect is not very good.And in long-distance transport or long-term use, plate right relative dislocation and distortion can appear unavoidably, make bad internal leakage or the two media aliasing of causing of sealing.

The purpose of this utility model is to provide a kind of under high-temperature vapour heat exchange state, and good sealing effect, nothing leakage, indeformable, both withstand voltage heat-resisting are difficult for producing dislocation, are out of shape and leakage, but and the high box tack welding fishplate bar sheet heat exchanger of heat exchange efficiency.

Scheme of the present utility model is as described below: this utility model comprises that heat transferring plate is to, hold-down bolt and sealing gasket, by the location crossbeam that is provided with in the rectangular box locate one group by a diagonal angle be corner cut, set runner hole, another diagonal angle around have one to include the heat transferring plate that is provided with O-ring seals in the seal groove in crossbeam hole, location and the groove right, and the inboard is provided with block around compressing one of sealing by hold-down bolt, and is provided with at location crossbeam external part that the case lid of seal closure realizes.

The utility model is owing to taked the plate that has corner cut and seal groove of location in the casing right, be provided with the combination of the cover structure and the O-ring seals of block and seal closure, make this utility model not only improve withstand voltage, heat-resisting index effectively, improved service behaviour, widened range of application, and have the project organization advantages of simple, novel unique, shock-resistant indeformable, do not misplace, inside and outsidely all do not have leakage, saving material, good sealing effect, heat exchange efficiency height, safe and reliable a, advantage such as dismounting is easy to maintenance.

In conjunction with the accompanying drawings scheme of the present utility model is described further:

But Fig. 1 is the overall structure schematic diagram of box tack welding fishplate bar sheet heat exchanger;

Fig. 2 is but that the heat transferring plate of box tack welding fishplate bar sheet heat exchanger is to plate face structural representation;

But Fig. 3 is the block structure division cutaway view of box tack welding fishplate bar sheet heat exchanger;

But Fig. 4 is the seal closure structure partial cutaway view of box tack welding fishplate bar sheet heat exchanger.

But by Fig. 1---box tack welding fishplate bar sheet heat exchanger shown in Figure 4 be with a diagonal angle be corner cut, set runner hole, another diagonal angle 1 around one group of (the referring to a plurality of) heat transferring plate that includes crossbeam hole, location 2 is arranged, per two lump together, weld along its periphery, form a cavity body plate to 3, a plurality of such plates are stacked in a respective side to 3 are provided with in the rectangular box 4 of gusset, and plate is located 3 by the location crossbeam 5 that is provided with in the crossbeam hole, location 2.Each plate includes the Long Circle seal groove of locating crossbeam hole 2 to being provided with of runner hole, diagonal angle 1 on 3 on every side, O-ring seals 6 is set in the seal groove, and will locate crossbeam 5 with which, and each plate is sealed between 3, can separate the sealing problem of decision bit crossbeam 5 again.Install a sealing gasket 7 additional at the case mouth in addition, then will around the inboard be provided with block 8, the outside is equipped with the gusset (mainly being to press the distortion that causes in the opposing case) of even cloth and case lid 10 that corresponding location crossbeam 5 external parts are provided with seal closure 9 is connected and fixed, compresses sealing through hold-down bolt 11 and casing 4.Meanwhile also make each plate to compress between 3, O-ring seals 6 these utility models of sealing constitute the corner cut form that plate is taked 3 heat transferring plate, the shell side diagonal angle runners that purpose is to constitute in the casing 4 can be saved metal material again to improve heat exchange efficiency.Its used O-ring seals 6 and case mouth place sealing gasket 7 all select for use heat-resisting higher fluorubber to make, and improve functional reliability to prevent leakage under high temperature.

Claims
