Description

Technical Field

[0001] The present application relates to the technical field of plate heat exchangers, and in particular to an interlocking structure of plates and rubber pads of a high-pressure self-locking plate heat exchanger. Background Art

[0002] As a highly efficient heat exchange equipment, plate heat exchangers are widely used in various heat exchange occasions. However, traditional plate heat exchangers have certain limitations in terms of pressure bearing performance. Plates and rubber pads are prone to misalignment after assembly and pressing, resulting in a decrease in pressure bearing capacity.

[0003] To solve the misalignment problem, the existing technology usually increases the thickness of the plate or uses higher strength materials to improve the pressure bearing capacity, but these methods often increase manufacturing costs and may affect heat exchange efficiency, and do not fundamentally solve the problem of misalignment between the plate and the rubber pad. Utility Model Content

[0004] In response to the shortcomings of the prior art, the present application provides an interlocking structure of plates and rubber pads for a high-pressure self-locking plate heat exchanger, which can enable the plates and rubber pads to interlock, effectively preventing the misalignment problem under high pressure, thereby significantly improving the pressure-bearing performance of the plate heat exchanger. At the same time, it can also effectively avoid assembly errors, further improving the stability and reliability of the equipment, and solving the problem that plates and rubber pads in plate heat exchangers are easily misaligned under high pressure, thereby resulting in a decrease in pressure-bearing performance.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an interlocking structure of a high-pressure self-locking plate heat exchanger plate and a rubber pad, comprising a rubber pad, wherein the upper surface and the bottom surface of the rubber pad are provided with plates, each of the plates is provided with two interlocking grooves, each of the plates is provided with a first dovetail groove, each of the plates is provided with a second dovetail groove, the inner side wall of each of the plates is fixedly connected with a first limiting protrusion arranged equidistantly, the inner bottom wall of the first dovetail groove is provided with a second limiting protrusion arranged equidistantly, and the inner top wall of the second dovetail groove is provided with a third limiting protrusion arranged equidistantly.

[0006] Through the above scheme, since the plates and rubber pads in the plate heat exchanger are easily misplaced under high pressure, which leads to a decrease in the pressure-bearing performance, the interlocking grooves, interlocking protrusions, first dovetail grooves, first dovetail protrusions, second dovetail grooves, and second dovetail protrusions are provided to enable the plates and rubber pads to be interlocked, effectively preventing the misplacement problem under high pressure, thereby significantly improving the pressure-bearing performance of the plate heat exchanger, and effectively avoiding assembly errors, further improving the stability and reliability of the equipment.

[0007] Furthermore, two interlocking protrusions are provided at the bottom end of the rubber pad, and the interlocking protrusions are respectively embedded in the interior of the plate through interlocking grooves.

[0008] Through the above scheme, during the assembly process, when the plates and the rubber pads are tightly combined together, the interlocking protrusions on the rubber pads will be embedded in the interlocking grooves of the plates, thereby forming a stable interlocking structure, which effectively prevents misalignment between the plates and the rubber pads under high-pressure working environments, thereby significantly improving the pressure-bearing performance of the plate heat exchanger.

[0009] Furthermore, a first dovetail protrusion is provided on the bottom surface of the rubber pad, and the first dovetail protrusion is embedded in the interior of the plate through a first dovetail groove.

[0010] Through the above solution, the first dovetail protrusion and the first dovetail groove can enhance the interlocking effect between the rubber pad and its bottom plate, and can also effectively prevent the rubber pad from sliding under high pressure environment.

[0011] Furthermore, a second dovetail protrusion is provided on the upper surface of the rubber pad, and the second dovetail protrusion is embedded in the interior of the plate through a second dovetail groove.

[0012] Through the above solution, the second dovetail protrusion and the second dovetail groove can enhance the interlocking effect between the rubber pad and the top plate thereof, and can also effectively prevent the rubber pad from sliding under high pressure environment.

[0013] Furthermore, the outer surface of the rubber pad is provided with first limiting grooves which are arranged at equal intervals, and the positions of the first limiting grooves correspond to the positions of the first limiting protrusions respectively.

[0014] Through the above solution, the first limiting protrusion and the first limiting groove can increase the friction between the two sides of the rubber pad and the plate, further preventing relative sliding under high pressure environment, thereby improving the stability and pressure bearing capacity of the plate heat exchanger.

[0015] Furthermore, the bottom surface of the first dovetail protrusion is provided with second limiting grooves which are arranged at equal intervals, and the positions of the second limiting grooves correspond to the positions of the second limiting protrusions.

[0016] Through the above scheme, the second limiting protrusion and the second limiting groove can increase the friction between the rubber pad and its bottom plate, further preventing relative sliding under high pressure environment, thereby improving the stability and pressure bearing capacity of the plate heat exchanger.

[0017] Furthermore, the upper surface of the second dovetail protrusion is provided with third limiting grooves which are arranged at equal intervals, and the positions of the third limiting grooves correspond to the positions of the third limiting protrusions.

[0018] Through the above solution, the third limiting protrusion and the third limiting groove can increase the friction between the rubber pad and the top plate thereof, further preventing relative sliding under high pressure environment, thereby improving the stability and pressure bearing capacity of the plate heat exchanger.

[0019] Furthermore, the interlocking protrusion is made of fluororubber, the first dovetail protrusion is made of fluororubber, and the second dovetail protrusion is made of fluororubber.

[0020] Through the above scheme, fluororubber has excellent high temperature and high pressure resistance, which can increase the service life of the interlocking structure and maintain the stability of the structure in more severe working environments, thereby improving the overall performance of the plate heat exchanger.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The interlocking structure of the plate and rubber pad of the high-pressure self-locking plate heat exchanger enables the plate and the rubber pad to interlock by arranging interlocking grooves, interlocking protrusions, a first dovetail groove, a first dovetail protrusion, a second dovetail groove, and a second dovetail protrusion, thereby effectively preventing the misalignment of the rubber pad under high pressure, thereby significantly improving the pressure-bearing performance of the plate heat exchanger, and effectively avoiding assembly errors, further improving the stability and reliability of the equipment, and solving the problem that the plates and rubber pads in the plate heat exchanger are easily misaligned under high pressure, thereby causing a decrease in the pressure-bearing performance.
