Description

Technical Field

[0001] This utility model relates to the field of textile heat exchanger technology, and in particular to a combined high-efficiency heat exchanger. Background Technology

[0002] Heat exchangers in setting machines play a crucial role in temperature control and thermal management on textile printing and dyeing production lines. They achieve efficient heat transfer and temperature regulation between heat sources such as steam, hot oil, and hot water and the setting chamber, ensuring uniform temperature rise and fall, stable humid and hot conditions, and high energy utilization efficiency during the setting process. Textile printing and dyeing is the process of applying colors and patterns to fibers and fiber products through physical, chemical, and thermal treatment methods. It typically includes pretreatment, dyeing, setting, and finishing stages, using different dyes, auxiliaries, and process parameters to comprehensively optimize the fabric's hand feel, luster, and durability.

[0003] However, traditional heat exchangers typically meet heat transfer requirements with a fixed length and a fixed number of tubes. Expanding capacity requires redesigning or replacing the entire unit, increasing upfront costs and downtime. If increased output or temperature control capability is needed, it is often only possible to replace the unit with a larger capacity unit or add parallel units, and heat conversion cannot be performed efficiently.

[0004] Therefore, those skilled in the art have provided a combined high-efficiency heat exchanger to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular high-efficiency heat exchanger. The heat exchanger's shell and tube assembly can be spliced ​​together with another shell and tube assembly via a first flange, sealing block, and sealing groove. This extends the heat exchange distance and adjusts the total heat transfer area, allowing the heat exchanger's shell and tube assembly mechanism to be spliced ​​together with a suitable number of shells and tubes as needed. Simultaneously, the gaps between the shells and tubes allow for mixing and heat conduction of the liquid after heat exchange, thereby improving the heat exchanger's efficiency. Furthermore, the modular splicing structure facilitates replacement of damaged components, enhancing the convenience of maintenance and extending the heat exchanger's service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A combined high-efficiency heat exchanger includes a tube body mechanism, which includes a tube shell. A first flange is fixedly connected to both the front and rear ends of the outer wall of the tube shell. A gas supply pipe is fixedly connected to both the front and rear ends of the upper part of the outer wall of the tube shell. A connecting pipe is fixedly connected to the upper surface of the gas supply pipe. Multiple guide plates are fixedly connected to the middle of the inner wall of the tube shell. Multiple heat exchange tubes are snap-fitted onto the outer wall of the guide plates. A hexagonal rotating block is fixedly connected to the front end of the outer wall of each heat exchange tube. A hexagonal nut is threaded onto the rear end of the outer wall of each heat exchange tube. Limiting grooves are formed at both the front and rear ends of the inner wall of the tube shell, and a limiting frame is snap-fitted onto the inner wall of the limiting groove. Both the front and rear ends of the pipe body mechanism are provided with pipe cover mechanisms. The pipe cover mechanism includes a first cover plate and a second cover plate. The rear end of the outer wall of the first cover plate and the front end of the outer wall of the second cover plate are fixedly connected to a fifth flange. The outer wall of the rear end of the first cover plate is provided with a third sealing groove. The outer wall of the front end of the second cover plate is fixedly connected to a third sealing block.

[0007] Through the above technical solution, the heat exchanger is assembled and connected by splicing the cover plate, shell, limiting frame and heat exchange tube, which makes it easy for users to clean the various components inside the heat exchanger, reduce the accumulation of dirt and improve the safety of the heat exchanger.

[0008] Furthermore, the front and rear ends of the lower part of the outer wall of the tube shell are fixedly connected to support legs, and the lower surface of the support legs is fixedly connected to a base plate; The above technical solution enables the device to be placed and stored in the required ground location via the support legs and base plate.

[0009] Furthermore, a third flange is fixedly connected to both ends of the outer wall of the connecting pipe, and a second flange is fixedly connected to the upper end of the outer wall of the gas transmission pipe. The above technical solution involves using a second flange and a third flange to bolt the connection between the connecting pipe and the gas transmission pipe.

[0010] Furthermore, a first sealing groove is provided on the outer wall of the rear end of the tube shell, and a first sealing block is fixedly connected to the outer wall of the front end of the tube shell; Through the above technical solution, the first sealing groove and the first sealing block are engaged to fix the multiple tube shells together and between the tube shells and the cover plate with sealing bolts.

[0011] Furthermore, a plurality of first positioning grooves are provided in the middle of the outer wall of the guide plate, and a second positioning groove is provided around the outer wall of the limiting frame near the tube shell. The above technical solution, in conjunction with the first positioning groove and the second positioning groove, allows the heat exchange tube to be threadedly installed and fixed inside the tube shell.

[0012] Furthermore, a second sealing block is fixedly connected to the inner wall of one end of the limiting slot, and a plurality of second sealing slots are opened in the middle of the outer wall of one end of the limiting frame. Through the above technical solution, the heat exchange tube is installed in the limiting card slot by the snap-fit ​​between the second sealing card block and the second sealing card groove.

[0013] Furthermore, the first cover plate is fixedly connected to the outer wall of the front end of the tube shell, and the second cover plate is fixedly connected to the outer wall of the rear end of the tube shell. The above technical solution enables users to bolt the first cover plate and the second cover plate onto the interlocking pipe shell.

[0014] Furthermore, an infusion tube is fixedly connected to the center of the outer wall of both the first cover plate and the second cover plate, and a fourth flange is fixedly connected to one end of the outer wall of the infusion tube. The above technical solution enables the infusion pipe to be connected to the liquid pipeline via the fourth flange, thereby allowing the input and output of the liquid requiring heat exchange.
