Description

Technical Field

[0001] The utility model belongs to the technical field of plate heat exchangers, and in particular relates to a sealing gasket with high sealing performance suitable for plate heat exchangers. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchange device that uses a series of corrugated metal plates to transfer heat between two fluids of different temperatures. These metal plates are designed into a special shape to increase the contact area and turbulence, thereby improving heat transfer efficiency. Plate heat exchangers are widely used in industries such as chemical industry, food processing, HVAC, seawater desalination, and pharmaceuticals.

[0003] Nowadays, the sealing gaskets used in plate heat exchangers may fall off, which will affect the working effect of the plate heat exchanger and reduce the working efficiency of the plate heat exchanger. In addition, the plate heat exchanger will cause wear on the fallen sealing gaskets during operation, reducing the service life of the plate heat exchanger sealing gaskets and directly increasing the maintenance cost of the equipment. Therefore, a sealing gasket with high sealing performance suitable for plate heat exchangers is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the sealing gasket used in the plate heat exchanger may fall off, which affects the working effect of the plate heat exchanger, and to propose a sealing gasket with high sealing performance suitable for the plate heat exchanger.

[0005] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a sealing gasket with high sealing performance suitable for a plate heat exchanger, comprising a plate body, a colloid provided on the side wall of the plate body, an anti-slip component provided on the side wall of the colloid, and a sealing component provided inside the colloid;

[0006] The anti-slip assembly includes a slat, a spring sleeve and a splint. A limiting groove is provided on the side wall of the slat. A first telescopic spring is fixedly installed on the inner wall of the bottom surface of the spring sleeve. An extrusion rod is fixedly installed on one end of the first telescopic spring. A limiting block is fixedly installed on the side wall of the splint. The outer wall of the limiting block is adapted to the inner wall of the limiting groove.

[0007] As a further description of the above technical solution:

[0008] The other side wall of the strip is fixedly connected to the side wall of the colloid, and the bottom inner wall of the limiting groove is fixedly connected to one end of the spring sleeve.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the extrusion rod is slidably connected to the inner wall of the spring sleeve, and one end of the extrusion rod extends to the outside of the spring sleeve.

[0011] As a further description of the above technical solution:

[0012] One end of the extrusion rod is fixedly connected to the side wall of the limiting block, and the inner wall of the clamping plate is in contact with the side wall of the plate body.

[0013] As a further description of the above technical solution:

[0014] The sealing assembly includes a second telescopic spring, one end of the second telescopic spring is fixedly mounted with the first top plate, and the other end of the second telescopic spring is fixedly mounted with the second top plate.

[0015] As a further description of the above technical solution:

[0016] The side wall of the first top plate is fixedly connected to the inner wall of the top surface of the colloid, and the side wall of the second top plate is fixedly connected to the inner wall of the bottom surface of the colloid.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In the utility model, an anti-slip component is provided. At this time, the colloid is placed on the card slot on the plate body, and then the splint is loosened. At this time, under the elastic force of the first telescopic spring, the first telescopic spring will pull the limit block into the limit slot through the extrusion rod to avoid affecting the limit block during work, and then the limit block drives the splint to clamp the plate body, so that the colloid on the plate body is kept stable through the splint. Similarly, the remaining splints clamp the plate body to prevent the sealing gasket from accidentally falling off during operation, reduce abnormal wear caused by improper installation or vibration, etc., can effectively extend the service life of the sealing gasket, help ensure that the sealing effect remains in good condition for a long time, and maintain the working efficiency of the equipment.

[0019] 2. In the present invention, a sealing assembly is provided, and then the plate body is installed on the plate heat exchanger. At this time, the two plates will squeeze the colloid in the middle. At this time, under the elastic force of the second telescopic spring in the colloid, the second telescopic spring will squeeze the first top plate and the second top plate. The provision of two top plates helps to increase the supporting force of the spring. The first top plate and the second top plate are squeezed by the second telescopic spring to press the two sides of the colloid tightly against the two plates, thereby increasing the sealing of the colloid, reducing unnecessary heat loss or cold loss, and the enhanced sealing helps to maintain a higher heat exchange efficiency, thereby reducing energy consumption and improving the overall operating economy.

[0030] When the cam 35 is in the closed position, the first spring 34 is released and the first spring 34 is released to release the first spring 34. When the cam 35 is in the closed position, the first spring 34 is released and the first spring 34 is released to release the first spring 34.

[0031] The sealing assembly 4 includes a second telescopic spring 42, one end of which is fixedly mounted with a first top plate 41, and the other end of the second telescopic spring 42 is fixedly mounted with a second top plate 43, the side wall of the first top plate 41 is fixedly connected to the top inner wall of the colloid 2, and the side wall of the second top plate 43 is fixedly connected to the bottom inner wall of the colloid 2.

[0032] The specific implementation method is as follows: the plate body 1 is then installed on the plate heat exchanger. At this time, the two plate bodies 1 will squeeze the colloid 2 in the middle. At this time, under the elastic force of the second telescopic spring 42 in the colloid 2, the second telescopic spring 42 will squeeze the first top plate 41 and the second top plate 43. The provision of two top plates helps to increase the supporting force of the spring. The first top plate 41 and the second top plate 43 are squeezed by the second telescopic spring 42, which will press the two sides of the colloid 2 tightly against the two plate bodies 1, thereby increasing the sealing of the colloid 2.

[0033] Working principle: When using the plate heat exchanger, first pull the clamping plate 37 on the slat 31 to one side.

At this time, under the support of the spring sleeve 33, the extrusion rod 35 will stretch the first telescopic spring 34 in the spring sleeve 33. At this time, place the colloid 2 on the card slot on the plate body 1, and then release the clamping plate 37. At this time, under the elastic force of the first telescopic spring 34, the first telescopic spring 34 will pull the limit block 36 into the limit groove 32 through the extrusion rod 35, and then The limit block 36 drives the clamping plate 37 to clamp the plate body 1, so that the colloid 2 on the plate body 1 is kept stable through the clamping plate 37. Similarly, the remaining clamping plates 37 clamp the plate body 1, and then the plate body 1 is installed on the plate heat exchanger. At this time, the two plate bodies 1 will squeeze the colloid 2 in the middle. At this time, under the elastic force of the second telescopic spring 42 in the colloid 2, the second telescopic spring 42 will squeeze the first top plate 41 and the second top plate 43. The first top plate 41 and the second top plate 43 are squeezed by the second telescopic spring 42 to press the two sides of the colloid 2 tightly against the two plate bodies 1, thereby increasing the sealing of the colloid 2.
