[0005] The purpose of this utility model is to provide a heat pipe heat exchanger with waste heat recovery, in order to solve the problem mentioned in the background art, where the heat pipe heat exchanger is equipped with a filter screen plate during use. After a long period of use, the filter screen plate needs to be disassembled and cleaned, and then reinstalled. Repeated disassembly and reassembly can cause the fasteners to loosen due to wear, increasing the difficulty of operation and reducing the stability after installation.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a heat pipe heat exchanger with waste heat recovery, comprising:

[0008] Heat exchanger casing;

[0009] The cleaning component includes an upper rotating shaft, an upper rotating rod, a lower rotating shaft, a lower rotating rod, a support frame, a cleaning brush, an upper top plate, a lower bottom plate, and a filter screen. The upper and lower rotating shafts are respectively connected to the upper and lower parts of the inner surface of the heat exchanger casing. The upper rotating rod is connected to the middle of the bottom end of the upper rotating shaft, and the lower rotating rod is connected to the middle of the bottom end of the lower rotating shaft. Support frames are connected to both sides of the outer surfaces of the upper and lower rotating rods, and the cleaning brush is connected between the two support frames.

[0010] Furthermore, the upper top plate and the lower bottom plate are respectively connected to the upper and lower parts of the inner surface of the heat exchanger casing, and a filter screen is detachably connected between the upper top plate and the lower bottom plate, with cleaning brushes attached to both sides of the outer surface of the filter screen.

[0011] Furthermore, the upper rotating rod is connected to the middle of the top of the upper plate, and the lower rotating rod is connected to the middle of the bottom of the lower plate.

[0012] Furthermore, it also includes a support component, which includes a movable rod and a movable groove. Movable grooves are provided on the upper and lower parts of the inner surface of the heat exchanger casing. A movable rod is connected to one side of the outer surface of the support frame, and the movable rod is movably connected inside the movable groove.

[0013] Furthermore, it also includes a collection component, which includes a support base, a collection frame, a pin holder, a pin block, a support rod, a cleaning plate, a hole, and a support seat. The lower part of both sides of the outer surface of the lower rotating rod is connected to the support rod, and a cleaning plate is connected to one side of the outer surface of the support rod. The bottom of the heat exchanger casing is connected to the support seat, and multiple holes are opened inside the support seat.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] This invention features a support frame and cleaning brushes inside the heat exchanger housing. A filter screen is used to filter the generated dust, and the cleaning brushes surround both sides of the filter screen's outer surface. A motor drives the upper rotating shaft, upper rotating rod, lower rotating shaft, and lower rotating rod to rotate, simultaneously rotating the outer cleaning brushes. This rotation cleans the dust adhering to the filter screen surface, eliminating the need to disassemble the filter screen for cleaning. This avoids the loosening of fasteners due to wear caused by repeated disassembly and reassembly, reducing operational difficulty and increasing post-installation stability.

[0017] Based on the aforementioned beneficial effects, a support rod is provided outside the lower rotating rod, and a cleaning plate is provided outside the support rod. The dust swept by the cleaning brush will settle inside the support base. When the lower rotating rod rotates, the support rod and the cleaning plate rotate simultaneously. The cleaning plate scrapes off the settled dust, allowing the settled dust to be transferred through the holes to the inside of the bottom collection frame, facilitating the cleaning of the settled dust inside. This eliminates the need to stop the heat exchanger casing, increasing work efficiency. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-4 As shown, this embodiment is a heat pipe heat exchanger with waste heat recovery, comprising:

[0032] Heat exchanger casing 11;

[0033] The cleaning component includes an upper rotating shaft 21, an upper rotating rod 22, a lower rotating shaft 23, a lower rotating rod 24, a support frame 25, a cleaning brush 26, an upper top plate 27, a lower bottom plate 28, and a filter screen 29. The upper rotating shaft 21 and the lower rotating shaft 23 are respectively connected to the upper and lower parts of the inner surface of the heat exchanger casing 11. The upper rotating rod 22 is connected to the middle of the bottom end of the upper rotating shaft 21, and the lower rotating rod 24 is connected to the middle of the bottom end of the lower rotating shaft 23. The support frame 25 is connected to both sides of the outer surface of the upper rotating rod 22 and the lower rotating rod 24. The cleaning brush 26 is connected between the two support frames 25.

[0034] The motor drives the upper rotating shaft 21, upper rotating rod 22, lower rotating shaft 23 and lower rotating rod 24 to rotate, and the outer cleaning brush 26 rotates at the same time. The dust attached to the surface of the filter screen 29 is cleaned by the rotation, without the need to disassemble the filter screen 29 for cleaning.

[0035] The upper top plate 27 and the lower bottom plate 28 are respectively connected to the upper and lower parts of the inner surface of the heat exchanger housing 11. A filter screen 29 is detachably connected between the upper top plate 27 and the lower bottom plate 28. A cleaning brush 26 is attached to both sides of the outer surface of the filter screen 29.

[0036] The upper plate 27 and the lower plate 28 can support the filter screen 29.

[0037] The upper rotating rod 22 is connected to the middle of the top of the upper top plate 27, and the lower rotating rod 24 is connected to the middle of the bottom of the lower base plate 28.

[0038] The rotation of the upper rotating rod 22 and the lower rotating rod 24 drives the upper top plate 27 and the lower bottom plate 28 to rotate simultaneously.

[0039] It also includes a support component, which includes a moving rod 31 and a moving groove 32. The upper and lower parts of the inner surface of the heat exchanger casing 11 are provided with moving grooves 32. The moving rod 31 is connected to one side of the outer surface of the support frame 25. The moving rod 31 is movably connected inside the moving groove 32.

[0040] When the cleaning brush 26 cleans the dust on the surface of the filter screen 29 by rotating, its moving rod 31 moves inside the moving groove 32 at the same time, which can play a supporting role.

[0041] The working principle is as follows: First, the filter screen 29 filters the generated dust. Cleaning brushes 26 surround both sides of the outer surface of the filter screen 29. The motor drives the upper rotating shaft 21, upper rotating rod 22, lower rotating shaft 23, and lower rotating rod 24 to rotate. The outer cleaning brushes 26 rotate simultaneously. Through rotation, the dust attached to the surface of the filter screen 29 is cleaned. Meanwhile, the moving rod 31 moves inside the moving groove 32, which can play a supporting role. There is no need to disassemble the filter screen 29 for cleaning. This avoids the phenomenon that fasteners may become loose due to wear due to repeated disassembly and assembly, reduces the difficulty of operation, and increases the stability after installation.

[0042] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, and further includes a collection component. The collection component includes a support base 41, a collection frame 42, a pin bracket 43, a pin block 44, a support rod 45, a cleaning plate 46, a hole 48, and a support seat 47. The lower part of both sides of the outer surface of the lower rotating rod 24 is connected to the support rod 45, and one side of the outer surface of the support rod 45 is connected to the cleaning plate 46. The bottom of the heat exchanger casing 11 is connected to the support seat 47. The support seat 47 has multiple holes 48 inside, and the cleaning plate 46 is attached to the top of the inner surface of the support seat 47.

[0043] When the rotating rod 24 rotates, the support rod 45 and the cleaning plate 46 rotate simultaneously. The cleaning plate 46 scrapes away the settled dust, allowing the settled dust to be transferred through the hole 48 to the inside of the bottom collection frame 42.

[0044] The bottom of the support base 47 is connected to the support base 41, the bottom of the support base 41 is connected to the collection frame 42, the two sides of the bottom of the support base 41 are connected to the pin bracket 43, the upper part of the two sides of the outer surface of the collection frame 42 is connected to the pin block 44, and the pin block 44 is inserted into the inside of the pin bracket 43.

[0045] Pull the collection frame 42 outward to separate the pin block 44 from the pin bracket 43, and remove the collection frame 42 to facilitate the unified cleaning of the dust collected inside.

[0046] The working principle is as follows: First, the dust cleaned by the brush 26 settles inside the support base 47. When the rotating rod 24 rotates, the support rod 45 and the cleaning plate 46 rotate simultaneously. The cleaning plate 46 scrapes away the settled dust, allowing it to be transferred through the hole 48 to the bottom collection frame 42 for easy cleaning. This eliminates the need to stop the heat exchanger casing 11, increasing work efficiency. As the collection time increases, the collection frame 42 is pulled outward, separating the pin block 44 from the pin bracket 43. The collection frame 42 is then disassembled for easy cleaning of the collected dust.
