Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and more specifically, to a honeycomb double-layer heat exchanger. Background Technology

[0002] In the process of treating chemical waste gas, honeycomb double-layer heat exchangers play an important role in heat recovery and resource utilization. The honeycomb double-layer heat exchanger adopts a double-layer structure and increases the heat exchange area by honeycomb flow channel design, which is higher than that of traditional tube heat exchangers, thus significantly improving heat exchange efficiency.

[0003] Among existing published documents, patent publication number CN218410801U discloses a heat exchanger. This technology uses the distance between the outer wall surface of the first component and the centerline of the first tube as the distance between the inner wall surface of the first tube and the centerline of the first tube. This utility model improves the thermal stress distribution of the heat exchanger and enhances its reliability. However, this technology still has the following drawbacks.

[0004] In the process of chemical waste gas treatment, honeycomb double-layer heat exchangers can achieve heat energy recovery and resource utilization by allowing cooling water to enter the heat exchanger and achieve heat dissipation through the fins on the surface of the heat exchanger. However, after heat dissipation, some impurities will adhere to the heat dissipation fins on the outside of the heat exchanger, making it difficult to quickly separate and clean the external heat exchange fins. This makes the later maintenance and cleaning of the heat exchanger more time-consuming and labor-intensive. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a honeycomb double-layer heat exchanger, including a heat exchange tube, with multiple transverse fins fixedly connected to the outer wall of the heat exchange tube, and longitudinal fins slidably provided on both sides of the transverse fins. A separation and cleaning assembly is provided on the upper surface of the transverse fins. The separation and cleaning assembly includes a support bar fixedly disposed on the upper surface of the transverse fins, a guide groove column fixedly connected to the upper surface of the support bar, and a concave sleeve plate slidably connected to the outer wall of the guide groove column. The upper surfaces of the two longitudinal fins are fixedly connected to the concave sleeve plate. A magnetic block is fixedly connected to one side of the inner wall of the guide groove column, and a magnet is magnetically connected to one side of the magnetic block. A pull buckle is fixedly connected to one side of the magnet.

[0006] Preferably, gaps are provided between the plurality of transverse fins, and the two longitudinal fins are symmetrically arranged about the transverse fins. The outer wall of the guide post and the inner wall of the concave sleeve are both smooth surfaces, and both the guide post and the concave sleeve are made of stainless steel. The magnet is slidably connected to the guide post, and the outer wall of the magnet and the inner wall of the guide post are both smooth surfaces.

[0007] In use, this technology achieves double-layer heat exchange in both the transverse and longitudinal directions using multiple transverse fins and two longitudinal fins. The pull-button moves the magnet to the right, and at the same time, the magnet and the magnetic block separate magnetically, and the magnet no longer engages with the guide slot column. The concave sleeve moves the two longitudinal fins upward synchronously, and the two longitudinal fins slide steadily upward along both sides of the outer wall of the transverse fins. The two longitudinal fins move upward and separate from both sides of the transverse fins, which facilitates the separation and cleaning of the longitudinal and transverse fins in the later stage.

[0008] Preferably, a lifting handle is provided on one side of the guide groove column, and the lifting handle is fixedly connected to the concave sleeve plate; the vertical cross-sectional shape of the lifting handle is concave; a cooling liquid inlet pipe is fixedly connected to one end of the heat exchange tube, and a liquid outlet pipe is fixedly connected to the other end of the heat exchange tube, both of which are made of stainless steel. Each longitudinal fin layer has multiple honeycomb holes inside, and the vertical cross-sectional shape of each honeycomb hole is polygonal. A connecting slider is fixedly connected to the outer wall of the magnet on the side adjacent to the pull buckle; a sliding column is slidably connected to the inner wall of the connecting slider, and a sliding strip is fixedly connected to the upper surface of the sliding column, the sliding strip and the slider are slidably connected, a support block is fixedly connected to one end of the sliding strip, and the support block is fixedly connected to the concave sleeve plate; an arc-shaped buckle is fixedly installed on the inner wall of the pull buckle.

[0009] When using this technology, a finger can be inserted into the arc-shaped buckle inside the pull tab. The pull tab causes the magnet to move to the right, which in turn causes the connecting slider to move to the right. The connecting slider moves to the right synchronously along the outer wall of the sliding post and the sliding strip, and the magnet quickly separates from the guide groove post.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts a separation cleaning component. The magnet no longer engages with the guide groove column. By lifting the handle upward, the concave sleeve plate moves upward, and the two longitudinal layer fins slide stably upward along both sides of the outer wall of the transverse layer fins. At the same time, the transverse layer fin support bar separates the two longitudinal layer fins from both sides of the transverse layer fins. This makes it easier to separate the longitudinal and transverse layer fins in the later stage, and the heat exchanger is more time-saving and labor-saving for later maintenance and cleaning.

[0012] 2. This utility model adopts a right-moving arc-shaped buckle. The arc-shaped buckle drives the pull buckle to move to the right, the pull buckle drives the magnet to move to the right, and the connecting slider moves to the right synchronously along the outer wall of the sliding column and the sliding strip, so that the magnet and the guide groove column can be separated quickly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1 - Appendix Figure 4 The diagram shows a honeycomb double-layer heat exchanger, which is equipped with a separation and cleaning component. The separation and cleaning component allows the two longitudinal layer fins 3 to move upward and separate from the sides of the transverse layer fins 2, making it easier to separate the longitudinal layer fins 3 and the transverse layer fins 2 in the later stages. This makes the later maintenance and cleaning of the heat exchanger more time-saving and labor-saving. The specific structure of the separation and cleaning component is as follows.

[0020] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 4As shown, longitudinal layer fins 3 are slidably arranged on both sides of the transverse layer fin 2. A separation and cleaning assembly is provided on the upper surface of the transverse layer fin 2. The separation and cleaning assembly includes a support bar 4 fixedly arranged on the upper surface of the transverse layer fin 2. A guide groove post 5 is fixedly connected to the upper surface of the support bar 4, and a concave sleeve plate 6 is slidably connected to the outer wall of the guide groove post 5. The upper surfaces of the two longitudinal layer fins 3 are fixedly connected to the concave sleeve plate 6. A magnetic block 7 is fixedly connected to one side of the inner wall of the guide groove post 5, and a magnet 8 is magnetically connected to one side of the magnetic block 7. A pull buckle 9 is fixedly connected to one side of the magnet 8. There are gaps between the multiple transverse layer fins 2, and the two longitudinal layer fins 3 are symmetrically arranged about the transverse layer fins 2. The outer wall of the guide groove post 5 and the inner wall of the concave sleeve plate 6 are both smooth surfaces, and both the guide groove post 5 and the concave sleeve plate 6 are made of stainless steel. The magnet 8 is slidably connected to the guide groove post 5, and the outer wall of the magnet 8 and the inner wall of the guide groove post 5 are both smooth surfaces.

[0021] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 2 As shown, a lifting handle 10 is provided on one side of the guide column 5, and the lifting handle 10 is fixedly connected to the concave sleeve plate 6. The vertical cross-section of the lifting handle 10 is concave, so that by lifting the lifting handle 10 upward, the lifting handle 10 drives the concave sleeve plate 6 upward, realizing the upward separation of the concave sleeve plate 6. One end of the heat exchange tube 1 is fixedly connected to the cooling liquid inlet pipe 11, and the other end of the heat exchange tube 1 is fixedly connected to the liquid outlet pipe 12. Both the cooling liquid inlet pipe 11 and the liquid outlet pipe 12 are made of stainless steel. Each longitudinal layer fin 3 has multiple honeycomb holes 13 inside. The vertical cross-section of the multiple honeycomb holes 13 is polygonal, so that the cooling liquid inlet pipe 11 is connected to the cooling water delivery pipe, and the liquid outlet pipe 12 is connected to the return pipe. In this way, the cooling water enters the heat exchange tube 1 along the cooling liquid inlet pipe 11, and achieves double-layer heat exchange in both the horizontal and vertical directions through multiple horizontal layer fins 2 and two vertical layer fins 3. The double-layer heat exchange effect is better.

[0022] In the operation of this honeycomb double-layer heat exchanger, during heat exchange, the cooling inlet pipe 11 is connected to the cooling water delivery pipe, and the outlet pipe 12 is connected to the return pipe. Cooling water enters the heat exchange tube 1 through the cooling inlet pipe 11, achieving double-layer heat exchange both horizontally and vertically through multiple transverse fins 2 and two longitudinal fins 3. Simultaneously, the honeycomb holes 13 on the longitudinal fins 3 provide multi-position heat dissipation. After heat exchange, dust and impurities may adhere to the outer wall of the longitudinal fins 3. This is addressed by moving the pull buckle 9 to the right, which causes the magnet 8 to move to the right. The magnet 8 slides out along the inner wall of the guide groove 5, and simultaneously, the magnet 8 and the magnetic attraction block 7 magnetically separate. When the iron 8 no longer engages with the guide post 5, the upward lifting handle 10 moves the concave sleeve 6 upward, causing the two longitudinal layer fins 3 to move upward simultaneously. The two longitudinal layer fins 3 slide steadily upward along both sides of the outer wall of the transverse layer fin 2. At the same time, the transverse layer fin 2 supports the support bar 4, increasing the stability of the support bar 4. In this way, the support bar 4 supports the guide post 5, allowing the two longitudinal layer fins 3 to move upward and separate from both sides of the transverse layer fin 2. This allows the longitudinal layer fins 3 to be cleaned, and facilitates the separation of the longitudinal layer fins 3 and transverse layer fins 2 in the future, enabling quick maintenance and use of the longitudinal layer fins 3 and transverse layer fins 2.

[0023] In this embodiment, as shown in the appendix Figure 4 As shown, a sliding block 14 is fixedly connected to the outer wall of the magnet 8 and to the side adjacent to the buckle 9; a sliding post 15 is slidably connected to the inner wall of the sliding block 14, and a sliding strip 16 is fixedly connected to the upper surface of the sliding post 15. The sliding strip 16 is slidably connected to the slider 14, and a support block 17 is fixedly connected to one end of the sliding strip 16. The support block 17 is fixedly connected to the concave sleeve plate 6; an arc-shaped buckle 18 is fixedly installed on the inner wall of the buckle 9.

[0024] During use, the honeycomb double-layer heat exchanger allows fingers to be inserted into the arc-shaped buckle 18 inside the pull buckle 9. Moving the arc-shaped buckle 18 to the right causes the pull buckle 9 to move to the right, which in turn causes the magnet 8 to move to the right. The magnet 8 then causes the connecting slider 14 to move to the right. The connecting slider 14 moves to the right synchronously along the outer walls of the sliding column 15 and the sliding strip 16. The concave sleeve plate 6 supports the support block 17, which in turn supports the sliding column 15 and the sliding strip 16. This stable movement of the magnet 8 to the right allows the magnet 8 to quickly separate from the guide groove column 5.
