Description

Technical Field

[0001] This utility model relates to the field of industrial water circulation heat exchange technology, and in particular to a heat exchange component for industrial water circulation. Background Technology

[0002] Industrial water circulation heat exchange components are key devices used to transfer heat between different media. They are commonly used in factory cooling, heating, or energy recovery systems. These components typically include plate heat exchangers, submerged heat exchangers, and other structures. The principle is that the flowing medium (such as a hot fluid) is introduced into the heat exchange tube, which is bent into an S-shape. The entire heat exchange tube is immersed in a tank filled with cooling water. Heat is transferred to the cooling water in the tank through heat exchange via the tube wall, thereby achieving the purpose of cooling the medium.

[0003] To prevent scale from entering the heat exchanger shell, submerged heat exchangers often have an interception structure installed in the liquid inlet pipe. However, to avoid affecting the cooling water circulation flow rate of the heat exchanger shell, the interception structure needs to be cleaned of scale after a period of operation. However, in the existing technology, cleaning the scale interception structure generally requires disassembling it from the shell, dumping the scale, and then reinstalling the interception structure on the heat exchanger shell, which is time-consuming. Moreover, workers need to completely drain the cooling water from the heat exchanger shell before the interception structure can be cleaned, resulting in a long time to restore the heat exchanger shell to its initial operating condition. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the prior art, when cleaning the scale interception structure of the heat exchanger shell, it is generally necessary to remove the interception structure from the shell, pour out the scale, and then reinstall the interception structure on the heat exchanger shell, which is time-consuming. In addition, workers need to completely drain the cooling water from the heat exchanger shell before the interception structure can be cleaned, which leads to a long time to restore the heat exchanger shell to its initial operating condition. Therefore, this invention proposes a heat exchange component for industrial water circulation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat exchange assembly for industrial water circulation includes a heat exchange box, a buffer tank, a horizontal cylinder, and a replenishment pipe. An S-shaped pipe is fixedly installed inside the heat exchange box, through which the medium flowing through the S-shaped pipe exchanges heat with the cooling water inside the heat exchange box. An outlet pipe is fixedly installed at the top of the heat exchange box, and a middle pipe is fixedly installed at the bottom edge of the heat exchange box, connected to the horizontal cylinder. An inlet pipe is fixedly connected to the horizontal cylinder below the middle pipe. A sludge outlet pipe is fixedly installed at the bottom edge of the horizontal cylinder, connected to the horizontal cylinder above the sludge outlet pipe, and its top is connected to the bottom of the buffer tank. A horizontally moving filter assembly is installed inside the horizontal cylinder to intercept scale in the cooling water. A follow-up cleaning assembly is installed on the side of the buffer tank, which, on the one hand, stops the heat exchange box from replenishing the buffer tank with cooling water, and on the other hand, allows the buffer tank to communicate with the outside atmosphere.

[0007] Optionally, the transverse filter assembly includes a horizontal column, a filter screen, and a horizontal cylinder. The horizontal cylinder is fixedly installed on the side of the horizontal cylinder, and the horizontal column is fixedly installed at the output end of the horizontal cylinder.

[0008] Optionally, the horizontal column extends into the inner cavity of the horizontal cylinder, and a cylindrical cavity is opened at the top of the horizontal column, with a filter screen fixedly installed inside the cylindrical cavity.

[0009] Optionally, the follow-up cleaning component includes a switching rod, a vertical cylinder, and an air intake bend. The air intake bend is fixedly connected to the top of the buffer tank, and the other end of the air intake bend faces the side of the heat exchange tank. The top of the side of the heat exchange tank is fixedly connected to one end of the supplementary pipe, and the other end of the supplementary pipe is fixedly connected to the side of the buffer tank. A timed exhaust valve is provided on the top of the buffer tank.

[0010] Optionally, a vertical cylinder is fixedly installed on the side of the buffer box, and a switching rod is fixedly installed at the output end of the vertical cylinder, which is movably inserted into the replenishment tube.

[0011] Optionally, the switching rod has an AC hole on the inner side of the supplementary pipe, and the top of the switching rod extends into the gap between the air inlet bend and the side of the heat exchange box.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The main structure of this utility model includes a heat exchange box, a buffer box, and a horizontal cylinder. The horizontal cylinder is equipped with a transverse filtration structure. The buffer box stores a certain amount of cooling water when the heat exchange box is working. A follow-up cleaning component is provided on the side of the buffer box. When it is necessary to clean the scale intercepted by the transverse filtration structure, the follow-up cleaning component works with the transverse filtration structure to use a portion of the cooling water buffered inside the buffer box to flush away the scale intercepted by the transverse filtration structure. The cleaning efficiency of the transverse filtration structure is improved to a certain extent, and it is not necessary to drain the cooling water inside the heat exchange box during this process.

[0020] Reference Figure 1-4 A heat exchange component for industrial water circulation includes a heat exchange box 1, a buffer box 4, a horizontal cylinder 9, and a replenishment pipe 3. An S-shaped pipe 6 is fixedly installed inside the heat exchange box 1, with both ends of the S-shaped pipe 6 located on the same side of the heat exchange box 1. The medium flowing through the S-shaped pipe 6 exchanges heat with the cooling water inside the heat exchange box 1. An outlet pipe 5 is fixedly installed at the top of the heat exchange box 1. An intermediate pipe 7 is fixedly installed at the bottom edge of the heat exchange box 1. The intermediate pipe 7 is fixedly connected to the horizontal cylinder 9. An inlet pipe 8 is fixedly connected to the horizontal cylinder 9 below the intermediate pipe 7. A sludge outlet pipe 10 is fixedly installed at the bottom edge of the horizontal cylinder 9. A return pipe 11 is fixedly connected to the horizontal cylinder 9 above the sludge outlet pipe 10. The top of the return pipe 11 is connected to the bottom of the buffer box 4. A transverse filter component is installed inside the horizontal cylinder 9.

[0021] The transverse filter assembly intercepts scale in the cooling water. The transverse filter assembly includes a horizontal column 16, a filter screen 14, and a horizontal cylinder 17. The horizontal cylinder 17 is fixedly installed on the side of the horizontal cylinder 9, and the horizontal column 16 is fixedly installed at the output end of the horizontal cylinder 17. The horizontal column 16 extends into the inner cavity of the horizontal cylinder 9. A cylindrical cavity 15 is opened at the top of the horizontal column 16. The filter screen 14 is fixedly installed inside the cylindrical cavity 15. The filter screen 14 is installed at the top of the cylindrical cavity 15, and the bottom of the cylindrical cavity 15 is used to accommodate and intercept a certain amount of scale.

[0022] A follow-up cleaning component is installed on the side of the buffer tank 4. This component stops the heat exchanger 1 from supplying cooling water to the buffer tank 4 and simultaneously connects the buffer tank 4 to the outside atmosphere. The follow-up cleaning component includes a switching rod 13, a vertical cylinder 12, and an intake bend 2. The intake bend 2 is fixedly connected to the top of the buffer tank 4, with its other end facing the side of the heat exchanger 1. The top side of the heat exchanger 1 is fixedly connected to one end of the replenishment pipe 3, and the other end of the replenishment pipe 3 is fixedly connected to the side of the buffer tank 4. A timed exhaust valve 41 is installed on the top of the buffer tank 4. This timed exhaust valve 41 is connected in series to the control circuit of the horizontal cylinder 17. When the horizontal cylinder 17 is fully extended, it can be opened for a certain period of time, allowing the buffer tank 4 to exhaust water to the outside, facilitating the buffer tank 4 to obtain cooling water from the heat exchanger 1 through the replenishment pipe 3.

[0023] A vertical cylinder 12 is fixedly installed on the side of the buffer box 4. A switching rod 13 is fixedly installed at the output end of the vertical cylinder 12. The switching rod 13 is movably inserted into the inside of the replenishment pipe 3. An exchange hole 131 is opened on the side of the inside of the replenishment pipe 3. The top of the switching rod 13 extends into the gap between the air inlet bend 2 and the side of the heat exchange box 1.

[0024] The specific implementation steps and principles of this utility model are as follows:

[0025] When the entire heat exchange assembly is in normal operation, the cylindrical cavity 15 is connected to the intermediate pipe 7 and the liquid inlet pipe 8. Cooling water enters the heat exchange box 1 through the liquid inlet pipe 8 and is discharged from the liquid outlet pipe 5 at the top of the heat exchange box 1. At this time, the vertical cylinder 12 is in the extended state, the AC port 131 is inside the replenishment pipe 3, and the top of the switching rod 13 fills the gap between the air inlet bend pipe 2 and the heat exchange box 1.

[0026] When it is necessary to clean the scale trapped in the filter screen 14, the horizontal cylinder 17 is activated to retract and the vertical cylinder 12 is activated. When the vertical cylinder 12 retracts, the exchange port 131 is removed from the replenishment pipe 3, and the gap between the heat exchange box 1 and the buffer box 4 is closed. At the same time, one end of the air inlet bend 2 is connected to the outside atmosphere. The replenishment pipe 3 drives the cylindrical cavity 15 to move to the middle of the return pipe 11 and the drain pipe 10. The cooling water inside the buffer box 4 is discharged from the filter screen 14 through the return pipe 11, and the scale trapped in the filter screen 14 is discharged from the drain pipe 10.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
