Abstract

The utility model relates to a lossless strengthening structure heating plate, belongs to heat exchange technology fields, and can be used as the heating element of energy-saving compact heat exchanger with steam as the heat source, which comprises two thin plates which are symmetrically stamped with grooves, a short section sawed by seamless steel tube, a component steel bolt, a steam condensate inlet and a steam condensate outlet. The utility model has the advantages that: one sides of the pairs of short sections arranged by triangle are all welded on the groove of one thin plate, the other sides of the short sections are all welded on the groove of the other thin plate, the bolt is inserted into the middle of the short sections in each groove after closed two thin plates, so the two thin plates are fastened together, the circumstances of the two thin plates and the steam condensate inlet and outlet are all welded, the utility model has no defects that conventional plug welding strengthen structure thin plate needs to perforate holes before welding, the thin plate base material is lossless and can be more reasonably thinned, the utility model can reduce manufacture cost and improve heat exchange efficiency, which is an ideal heating element of compact heat exchanger.

Description

The harmless structure heating plate of strengthening

Technical field

The utility model relates to a kind of harmless reinforcement structure heating plate, belongs to technical field of heat exchange, can constitute the heating element heater of compact heat exchanger, uses for chemical and medicine industry equipment.

Technical background

Need be the indirect energy saving heat exchanger of thermal source with steam in many chemical and medicine industry drying equipments, and wish that heat exchanger is compact as far as possible, so a lot of plug welding reinforcement structure of hollow heating plate that adopts is made heating element heater.This reinforcement structure is perforate on two thin plates, adds the short column welding again in the hole.The plate surface also needs polishing leveling after welding, and the area that causes welding seldom easily leaks gas in plate tapping generation sealing-off.Solder joint is a lot of on the plate, as long as the welding quality of indivedual solder joints goes wrong, will cause the chain serious situation of splitting cruelly of solder joint and take place.Because heating plate is arranged compactness, find the also difficult reparation of indivedual solder joint gas leakage on the plate again, have to the shutoff of monoblock heating plate.In order to remedy the above-mentioned defective plate thickness of also having to increase, not only strengthened equipment manufacturing cost but also increased thermal resistance.

Summary of the invention

The purpose of this utility model provides the harmless structure heating plate of strengthening, no longer need be on thin plate perforate and reach the intensity of strengthening heating plate, avoid traditional plug welding to strengthen the various drawbacks that structure produced.

The technical solution of the utility model is: it is imported and exported by thin plate, seamless pipe pipe nipple, first steel latch and steam condensation water and forms.Its feature is: symmetry stamps out for the fixing circular groove of pipe nipple on two thin plates up and down, a pair of by rounded projections arranged in adjacent trenches to pipe nipple, each is welded on the groove of a thin plate entirely to the side pipe nipple in the pipe nipple, the opposite side pipe nipple then is welded on the groove of another piece thin plate entirely, two thin plates close after whole pipe nipples welding on two thin plates are finished, latch is inserted in the pipe nipple of every groove, so latch two thin plates up and down tightly is fixed together, weld just becoming of steam condensation water import and export and heating plate then all around.

The utility model adopts the structure that stamped grooves is welded pipe nipple again on thin plate, both can improve the rigidity of heating plate, again can be correctly fixedly pipe nipple position and direction, the volume that can also reduce heating plate makes heating plate compacter.Because reaching structure, the not perforate of mother metal plate face strengthens, exempted the drawback that perforate plug welding reinforcement is produced, so sheet metal thickness is attenuate rationally, the heating plate cost is reduced and improve heat-transfer effect, this provides good and cheap compact conformation heating element heater to create conditions for various internal heating fluidized bed driers and large-scale board-like heat drying machine.

The specific embodiment

The utility model embodiment is described further in conjunction with the accompanying drawings, as Fig. 1, and 2,3,4, shown in, the harmless structure heating plate of strengthening is made up of the groove (2) that stamps out on thin plate (1), the thin plate, latch (3), pipe nipple (4) and steam condensation water import and export (5).Its feature is: the last symmetry of two thin plates (1) stamps out groove (2) about heating plate, in groove (2) a pair of to pipe nipple (4) by rounded projections arranged, the pipe nipple (4) of a side in every pair of pipe nipple (4) all is welded on the thin plate (1), whole pipe nipples (4) of opposite side then are welded on another piece thin plate (1), two thin plates are closed, latch (3) inserts pipe nipple (4) centering in every groove (2), imports and exports (5) with the welding steam condensation water around the weld heating plate then.

Claims

1. one kind can't harm reinforcement structure heating plate, it comprises by thin plate (1), the groove that stamps out on the thin plate (2), unit's steel latch (3), pipe nipple that seamless pipe is sawn into (4) and steam condensation water are imported and exported (5) and are formed, its feature is: go up symmetry at two thin plates (1) up and down of heating plate and stamp out groove (2), in groove (2), establish a pair of to pipe nipple (4) by rounded projections arranged, the pipe nipple (4) of a side in every pair of pipe nipple (4) all is welded on the groove (2) of a thin plate (1), the pipe nipple of opposite side (4) then all is welded on the groove (2) of another piece thin plate (1), two thin plates (1) that close insert latch (3) in the pipe nipple (4) on each bar groove (2) again, weld then steam condensation water import and export (5) and thin plate (1) around.
