Description

Technical Field

[0001] The utility model belongs to the technical field of plate-type heat exchange units, and in particular relates to a plate-type heat exchange unit which is convenient for replacing filters. Background Art

[0002] A plate heat exchanger is a high-efficiency heat exchanger made of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the various plates, and heat exchange is carried out through the plates. In order to ensure the cleanliness of the water flow inside the plate heat exchanger during use, a filter is used to filter the water flow.

[0003] The installation direction of existing filters is mostly consistent with the direction of the pipeline. The expansion and contraction of the pipeline needs to be adjusted during the installation and removal process, so the pipeline is required to be a hose, which has poor stability. The heat exchanger, filter and water supply pipeline are connected by hard pipes. There is not enough space to remove the filter, and the heat exchanger or water supply pipeline can only be moved, which further increases the difficulty of replacing the filter. At the same time, existing filters are mostly stabilized by bolts or threaded connections. Bolt fixing is time-consuming and labor-intensive, and threaded connection fixing requires sufficient reverse force to twist the filter, which is relatively laborious. Utility Model Content

[0021] The present invention provides a plate heat exchanger unit that is easy to replace the filter. Figure 1-4As shown, the plate heat exchanger unit that is easy to replace the filter includes: a plate heat exchanger body 1; a plurality of drain pipes 2, and the plurality of drain pipes 2 are installed on the plate heat exchanger body 1; a plurality of liquid inlet pipes 3, and the plurality of liquid inlet pipes 3 are fixed on the plate heat exchanger body 1 and respectively connected to the plurality of drain pipes 2, and the plurality of liquid inlet pipes 3 are each provided with a connecting pipe 4; a plurality of shells 5, and the plurality of shells 5 are respectively arranged on the plurality of connecting pipes 4; a plurality of support shells 10, and the plurality of support shells 10 are respectively detachably installed in the plurality of shells 5, and the plurality of support shells 10 are each provided with a filtering structure for filtering impurities in the liquid.

[0022] In this embodiment, the plate heat exchanger body 1 serves as the core part of the heat exchange unit and is responsible for the heat exchange of the liquid. It provides a stable platform for the installation of the filter, and there is no need to move the entire heat exchange unit for replacing the filter. Multiple drain pipes 2 are used to discharge the liquid after heat exchange, and cooperate with the liquid inlet pipe 3 to realize the circulation of the liquid without hindering the installation and disassembly of the filter. Through the connecting pipe 4, the shell 5 (and the filter inside) can be easily connected to the heat exchange system and is also easy to disassemble. The detachability of the support shell 10 makes it easy to replace the filter structure without moving the heat exchange unit or the water supply pipe. The filter structure effectively ensures the quality of the liquid entering the heat exchange unit, and its replaceability ensures the long-term stable operation of the unit.

[0023] In a further preferred embodiment of the present invention, the plurality of connecting pipes 4 are composed of a fixed pipe and an extension pipe, any one of the shells 5 is arranged between the fixed pipe and the extension pipe, two limiting rings 8 are installed in the plurality of shells 5, and a sealing ring 9 is installed on the side where the plurality of limiting rings 8 are close to each other, and the plurality of sealing rings 9 are respectively in contact with the outer walls on both sides of the plurality of support shells 10.

[0024] In this embodiment, the connecting pipe 4 consists of a fixed pipe and an extension pipe. The limiting ring 8 is used to limit the movement range of the support shell 10 in the shell 5 to prevent it from falling off or excessive movement. At the same time, the cooperation between the limiting ring 8 and the sealing ring 9 ensures the sealing between the support shell 10 and the shell 5 to prevent liquid leakage. The sealing ring 9 provides additional sealing protection to ensure a tight connection between the support shell 10 and the shell 5, which helps prevent liquid leakage during the filtration process, thereby ensuring the normal operation of the heat exchanger unit and the cleanliness of the liquid.

[0025] In a further preferred embodiment of the present invention, the filtering structure includes a filter box 11 and a filter membrane rack 12, the filter box 11 is installed in the supporting shell 10, the filter box 11 is filled with filter material, the filter membrane rack 12 is sleeved outside the filter box 11, the filter membrane rack 12 is detachably mounted on the inner wall of the supporting shell 10, the filter membrane is installed on the filter membrane rack 12, a blocking plate is fixed on the filter membrane rack 12, the filter box 11 is provided with a material taking port, and the blocking plate is used to close the material taking port.

[0026] In this embodiment, the filter box 11 provides a closed space for filling filter materials (such as activated carbon, sand and gravel, etc.) to effectively filter impurities in the liquid. Its structure is sturdy and can withstand a certain amount of liquid pressure and impact force, ensuring the stability and reliability of the filtration process. The filter membrane rack 12 provides a stable support platform for the filter membrane. At the same time, its detachability makes the replacement of the filter membrane simple and quick. The design of the filter membrane rack 12 also takes into account the fluidity and uniformity of the liquid to ensure that the filter membrane can fully exert its filtering effect. The blocking plate is fixed on the filter membrane rack 12 to close the material taking port on the filter box 11 to prevent the filter material from leaking. The material taking port is set on the filter box 11 for removing and replacing the filter material.

This design not only improves the fluidity of the liquid, but also ensures the continuity and efficiency of the filtration process. The design of the isolation net allows the filter box 11 to be stably installed in the support shell 10, while preventing the filter material from falling off or shifting due to liquid impact during the filtration process.
