Description

Prevent heat transfer slab of leakage

Technical Field

The utility model relates to the technical field of heat exchangers, in particular to a leakage-proof heat exchange plate.

Background

The heat exchange plate used by the existing wide-flow-channel plate heat exchanger is shown in fig. 1, and comprises two single plates 1a with the same structure, both ends of each single plate 1a are provided with a bending part 2a and a connecting edge 3a, the two single plates 1a are welded corresponding to the connecting edges 3a at both ends, and a water channel is formed in an area between the two single plates 1 a. One end of the heat exchange plate is a feeding end, the other end of the heat exchange plate is a discharging end, and in daily use, the flowing of slurry has large abrasion on the feeding end and the discharging end of the heat exchange plate, namely, the welding points of the connecting edge 3a of the single plate 1a and the welding point of the welding connecting edge 3a are easily abraded to cause the leakage phenomenon, so that the periodic repair is needed, and the maintenance cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a leakage-proof heat exchange plate to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a prevent heat transfer slab of leakage, includes two veneer pieces that the structure is the same, and the both ends of veneer piece are provided with the kink, the kink is connected with the connection limit, and connects limit and veneer piece parallel arrangement, connect the limit including last connection limit and lower connection limit, it is provided with U type recess to go up the connection limit, and goes up the connection limit middle part and be provided with first arch and first recess in turn, it is protruding that the connection limit is provided with the U type down, and connects the limit middle part down and be provided with protruding and the second recess in turn of second.

As a further improvement to the technical scheme, the upper connecting edge and the lower connecting edge are meshed and connected.

As a further improvement to the technical scheme, the upper connecting edge and the lower connecting edge are engaged and connected with the rear side surface and fixed through welding.

As a further improvement to the above technical scheme, a supporting column is arranged between the single plates.

As a further improvement to the technical scheme, a sealing gasket is arranged on the convex surface of the U-shaped protrusion.

The utility model has the technical effects and advantages that: according to the utility model, the connecting edges are provided with the structures such as the bulges and the grooves, so that the connecting edges are connected in a meshing manner and then welded, the condition that welding spots at two ends are leaked can be effectively avoided, the maintenance frequency is reduced, and the maintenance cost is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides a leakage-proof heat exchange plate sheet as shown in figures 1-4, which comprises two single plate sheets 1 with the same structure, wherein a support column 4 is arranged between the single plate sheets 1, two ends of each single plate sheet 1 are provided with bent parts 2, the bent parts 2 are connected with connecting edges 3, the connecting edges 3 are arranged in parallel with the single plate sheets 1, the connecting edges 3 of the two single plate sheets 1 comprise upper connecting edges 31 and lower connecting edges 32, U-shaped grooves 313 are arranged on the upper connecting edges 31, first bulges 311 and first grooves 312 are alternately arranged in the middle parts, the lower connecting edges 32 are matched with the upper connecting edges 31 to be provided with U-shaped bulges 323, the bulge surfaces of the U-shaped bulges 323 are provided with sealing gaskets, and second bulges 321 and second grooves 322 are alternately arranged in the middle parts, when in use, the U-shaped bulges 323 are engaged with the U-shaped grooves 313, the first bulges 311 are engaged with the second grooves 322, the second bulges 321 are engaged with the first grooves 312, the upper connecting edge 31 and the lower connecting edge 32 are engaged and connected, and the connecting side faces are fixed by welding, so that the welding and fixing connection of the connecting edges 3 at the two ends of the two single plates 1 is completed.

What need explain finally is traditional connection limit 3a, because the surface of connection limit 3a is the plain noodles, after the side welded fastening, if the welding point appears droing or wearing and tearing, the condition of seepage appears easily, this application is because last connection limit 31 and lower connection limit 32 meshing connection to be provided with structures such as sealed pad, after the side welding, even the wearing and tearing appear in some point, the condition of seepage can not appear yet, has reduced the maintenance number of times, reduces cost of maintenance.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
