Description

TECHNICAL FIELD

[0001] The utility model relates to a detachable plate heat exchanger with anti-skid sheet belongs to heat exchanger technical field. BACKGROUND

[0002] The detachable plate heat exchanger is composed of corrugated (metal) heat exchange plates, which are installed between a frame with fixed plates and movable compression plates and clamped by clamping bolts for fixation. Fluid channels formed between adjacent heat exchange plates guide fluid media to flow alternately into respective channels. Fluid channels of two kinds of fluid media are located on both sides of each heat exchange plate, i.e., their flow channels are staggered and spaced with each other, and heat exchange is performed through the metal heat exchange plates. The detachable plate heat exchanger is characterized in that the sheet can be detached for easy cleaning and maintenance.

[0003] The seal between the sheets in the detachable plate heat exchanger is generally achieved by using rubber gasket seals. The rubber gasket has a limit on the front and rear inner and outer sides, i.e., a groove for setting the rubber gasket. Since the main body of the sheet is of a corrugated structure, the limit on the inner side of the rubber gasket groove is in segments, not a continuous limit surface. When subjected to high pressure, the contact area between the sheets during installation is small, which can cause deformation of the limit on the side of the rubber gasket groove of the sheet, and the position of the rubber gasket without limit is prone to displacement, thereby causing leakage. Under the high pressure condition in the actual production and use process, the rubber gasket groove without limit between the sheets is also a position where leakage often occurs. SUMMARY

[0004] The utility model solves the technical problem of the prior art, provides a detachable plate heat exchanger with anti-skid sheet, prevents displacement of the sealing gasket between the sheets, avoids leakage between the sheets, and improves the pressure-bearing capacity and reliability of the heat exchanger.

[0005] The utility model adopts the technical scheme to solve the above problems: a detachable plate heat exchanger with anti-skid sheet, comprising a plurality of anti-skid corrugated heat exchange plates, the plurality of anti-skid corrugated heat exchange plates are stacked between a fixed plate and a movable compression plate, a gasket groove is formed on any anti-skid corrugated heat exchange plate, a sealing gasket is arranged in the gasket groove, the fluid channels formed between adjacent anti-skid corrugated heat exchange plates are sealed, and fluid media are guided to flow alternately into respective channels, one side of the gasket groove is a gasket groove outer inclined surface, the other side is a gasket groove inner inclined surface, the gasket groove outer inclined surface is a continuous inclined surface, the gasket groove inner inclined surface is a non-continuous inclined surface formed by alternating a limited inner inclined surface and an unlimited inner inclined surface, the corrugated groove on the anti-skid corrugated heat exchange plate intersects with the gasket groove through the unlimited inner inclined surface, an intersection corner b is arranged between the corrugated groove and the gasket groove, the corrugated groove and the gasket groove are perpendicular to each other, and a corrugated inclined surface is formed at the intersection of the corrugated groove and the gasket groove.

[0006] The intersection corner b ranges from 95° to 135°.

[0007] The limiting inner inclined surface area is 70% to 80% of the sum of the limiting inner inclined surface area and the unlimited inner inclined surface area.

[0008] Compared with the prior art, the anti-skid detachable plate heat exchanger has the advantages that the intersection corner is arranged between the corrugated groove and the rubber pad groove, the unlimited inner inclined surface and the rubber pad groove are vertically intersected, the anti-skid corrugated heat exchange plate supporting surface and the limiting inner inclined surface are increased, the displacement of the rubber pad is avoided, the leakage between the plates is prevented, and the pressure bearing capacity and reliability of the detachable heat exchanger are improved.
