Description

Technical Field

[0001] This utility model relates to the technical field of plate heat exchanger sealing gaskets, and in particular to plate heat exchanger sealing gaskets with positioning structures. Background Technology

[0002] Plate heat exchanger gaskets are a key component of heat exchangers, responsible for ensuring that the heat exchange medium does not leak and preventing cross-contamination between different media. The material of the gasket directly affects its temperature resistance, pressure resistance, and chemical resistance. Therefore, the appropriate material must be selected based on the working conditions and media type. When installing plate heat exchanger gaskets, it is necessary to check whether their model and specifications meet the equipment requirements and ensure that the gasket is flat and free from twisting during installation.

[0003] Traditional plate heat exchanger gaskets require fixing during heat exchange. However, excessively tight or loose pressure can cause the gaskets to fall off or shift, rendering them ineffective. This leads to cross-contamination during heat exchange, causing the hotter and colder components to mix. This can introduce impurities into the products being exchanged, affecting their performance and creating potential safety risks.

[0004] Therefore, for the aforementioned traditional plate heat exchanger gaskets, the gaskets need to be fixed during the heat exchange process. However, excessively tight or loose pressure can cause the gaskets to fall off or shift, rendering them ineffective. A six-point positioning method can be designed to prevent the gaskets from becoming loose due to excessive tightness or looseness. This prevents cross-contamination during heat exchange, avoiding mixing of hotter and colder components, thus preventing impurities from entering the products undergoing heat exchange, ensuring product performance is not affected, and reducing potential safety risks. Utility Model Content

[0005] To overcome the problem of traditional plate heat exchanger gaskets, which require fixing during heat exchange, excessively tight or loose pressure can cause the gaskets to fall off or shift, rendering them ineffective.

The lower end of the main board 1 is provided with a support column 301, and multiple sets of support columns 301 are provided. The lower end of the support column 301 is provided with a support foot 302. During use, the support column 301 supports the device, and the support foot 302 distributes the weight of the device, thereby preventing the device from shaking or collapsing. The support assembly also includes screw holes 303. Multiple sets of screw holes 303 are provided at the upper end of the support foot 302. During use, screws 506 are installed through the screw holes 303 to fix the support foot 302 in a specific position. The fixing assembly includes a fixing screw 401 and a fixing nut 402. A fixing screw 401 is provided on one side of the main board 1, penetrating both the main board 1 and the side plate 2. A fixing nut 402 is provided on the outside of the fixing screw 401. During use, the device is fixed by the fixing screw 401, and the fixing nut 402 is used to install the fixing screw 401, thereby preventing the device from falling off.

[0024] The fixing assembly also includes a support column 403 and a telescopic column 404; a support column 403 is provided on one side of the side plate 2, located on the side of the fixing nut 402, and a telescopic column 404 is provided on the other side of the support column 403, located on the side plate 2. In use, the telescopic column 404 is installed through the support column 403, and the telescopic column 404 extends and retracts, driving the side plate 2 to move, thereby compressing multiple sets of plates 601 and gaskets 604, thus facilitating fixation with fixing screws 401; the heat exchange assembly includes a corrugated groove 501, a hot water inlet 502, and a cold water inlet 503; a hot water inlet 502 is provided on one side of the main plate 1, a cold water inlet 503 is provided on one side of the main plate 1, and a corrugated groove 501 is provided on one side of the plate 601. The corrugated groove 501 has a complex internal circuit. In use, a hot fluid is introduced through the hot water inlet 502, and the heat exchanger... A colder fluid is introduced into the cold water inlet 503. At this time, the hot fluid enters the space formed by the first plate 601 and the gasket 604, and the cold fluid enters the space formed by the gasket 604 and the second plate 601. The flow time of the fluid is increased by the corrugated groove 501, thereby facilitating heat exchange. The heat exchange assembly also includes an upper positioning bracket 504, a lower positioning bracket 505, and mounting screws 506. The mounting screws 506 are provided on one side of the hot water inlet 502, and the upper positioning bracket 504 is provided on one side of the main board 1. The lower positioning bracket 505 is provided below the upper positioning bracket 504. In use, the upper positioning bracket 504 facilitates the placement of the plate 601 and the gasket 604, the lower positioning bracket 505 places and supports the plate 601 and the gasket 604, and the mounting screws 506 facilitate the fixing of the hot water inlet 502 to the pipe, thereby assisting in heat exchange.

[0025] During operation, the device is first supported by the support column 301, and the weight of the device is distributed by the support foot 302. The screw 506 is installed through the screw hole 303 to prevent the device from shaking or collapsing. Next, the upper positioning frame 504 facilitates the placement of the plate 601 and the gasket 604, and the lower positioning frame 505 places and supports the plate 601 and the gasket 604. Different plates 601 form different independent spaces. The positioning column 603 is fixed through the positioning hole 602. The positioning column 603 fixes the plate 601, the gasket 604, and another plate 601. The gasket 604 divides the two plates 601 and forms an independent space with the plate 601. The positioning column 603 is installed through the through hole 605. The glue block is placed through the glue groove 606 to fix the gasket 604 to the plate 601, so that the gasket 604 will not become loose.

[0026] Secondly, a telescopic column 404 is installed through the support column 403. The telescopic column 404 extends and retracts, causing the side plate 2 to move, thereby squeezing the multiple sets of plates 601 and gaskets 604, which makes it easy to fix with the fixing screws 401. Then, the device is fixed with the fixing screws 401, and the fixing screws 401 are installed with the fixing nuts 402 to prevent the device from falling off.

[0027] Finally, the hot water inlet 502 is easily fixed to the pipe by the mounting screw 506, thereby assisting in heat exchange. A hotter fluid is introduced through the hot water inlet 502 and a colder fluid is introduced through the cold water inlet 503. At this time, the hot fluid enters the space formed by the first plate 601 and the gasket 604, and the cold fluid enters the space formed by the gasket 604 and the second plate 601. The corrugated groove 501 increases the flow time of the fluid, thereby enabling heat exchange.

[0028] Through the above steps, the side plate 2 is used to fix the gasket 604, thereby preventing the device from falling off. The support assembly provides support, thus supporting the device. The fixing assembly provides fixation, thus fixing the main board 1 and the side plate 2 together. The heat exchange assembly provides heat exchange, thus facilitating heat exchange. Different plates 601 form different independent spaces. The positioning hole 602 fixes the positioning post 603, and the positioning post 603 fixes the plate 601, the gasket 604, and another plate 601. The gasket 604 separates... Two plates 601 are cut to form an independent space with each other. A positioning post 603 is installed using a through hole 605. An adhesive block is placed using an adhesive groove 606 to fix a gasket 604 to the plate 601. This ensures that the gasket 604 will not become loose due to being too tight or too loose, thereby preventing cross-contamination during heat exchange and preventing the hotter and colder components from mixing. This also prevents impurities from appearing in the products that need to be heat exchanged, ensuring that the product performance is not affected and reducing potential safety risks.
