The first mounting frame A mounting plate 33 is snapped into the interior of 30, and a waste water trough is opened on the front side of the upper part of the mounting plate 33 to allow waste water to pass through the mounting plate 33. A plurality of baffles 34 are connected to the left and right sides of the mounting plate 33, and heat absorption tubes 35 are connected between the baffles 34 on the same mounting plate 33. The heat absorption tubes 35 pass through adjacent mounting plates 33. A first butt joint tube 351 is connected to the left side of the lower part of the heat absorption tube 35, and the first butt joint tube 351 is snap-fitted with the adjacent second mounting frame 31. A second butt joint tube 352 is connected to the right side of the lower part of the heat absorption tube 35, and the second butt joint tube 352 is snap-fitted with the adjacent first mounting frame 30. A plurality of fins 36 are connected to the left and right parts of the heat absorption tube 35.

[0043] like Figure 1 , Figure 2 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the alignment clamping mechanism 4 includes a rotating frame 40, an alignment sleeve 41, a first spring 42, a third docking tube 43, a first clamping member 44, a second clamping member 45, a second bolt 46, a connecting rod 47, a guide rod 48, a pressing frame 49 and a second spring 410. The left sides of the front and rear parts of the second installation frame 31 are both rotatably connected to the rotating frame 40, the front and rear sides of the upper part of the second installation frame 31 are both connected to the alignment sleeve 41, the second conducting tube 311 and the first docking tube 351 are both slidably connected to the third docking tube 43, the third docking tube 43 is connected to the second conducting tube 311 and the first docking tube 351 connected with the first spring 42, and the two adjacent A first clamping member 44 is clamped between the upper sides of the third butt-jointing tubes 43, and a second clamping member 45 is detachably connected to the first clamping member 44 through two second bolts 46. The second clamping member 45 is located on the lower side of the adjacent third butt-jointing tubes 43. A connecting rod 47 is connected to the upper part of the first clamping member 44, and guide rods 48 are connected to the front and rear sides of the upper part of the second mounting frame 31. The guide rods 48 are located on the left part of the adjacent alignment sleeve 41. A pressing frame 49 is slidably connected between two vertically adjacent guide rods 48, and the connecting rod 47 is movably connected to the adjacent pressing frame 49. A second spring 410 is connected between the guide rod 48 and the connected pressing frame 49.

[0044] When using the present invention, firstly, the first mounting frame 30 and the second mounting frame 31 are spliced ​​together by the first bolt 32 to form a waste heat recovery box. A cavity is left between the first mounting frame 30 and the second mounting frame 31 to increase the thermal insulation performance. The waste heat recovery box is fixed on the mounting seat 1, and then, according to the waste heat recovery requirements of waste water, the mounting seat 1 is placed from top to bottom on the alignment plate 2 of another mounting seat 1, so that the mounting seat 1 and the alignment plate 2 are snap-fitted, so that the mounting seats 1 are spliced ​​together to adapt to different waste heat recovery requirements of waste water. When the mounting seat 1 is placed from top to bottom, the angle of the rotating frame 40 is rotated and adjusted so that when it is placed downward, the rotating frame 40 can be snap-fitted with the alignment sleeve 41 on the second mounting frame 31 on the left side, so that the two adjacent waste heat recovery The boxes are spliced ​​with each other stably. When the mounting seat 1 is placed from top to bottom, the pressing frame 49 is pressed to move downward, and the second spring 410 is squeezed and contracted, so that the pressing frame 49 pushes the connecting rod 47 to move to the right, driving the first clamping member 44 and the second clamping member 45 to move to the right, so that the third butt joint pipe 43 moves to the right, and the first spring 42 is squeezed and contracted. When the mounting seats 1 are spliced ​​with each other, the pressing frame 49 is released, and the second spring 410 rebounds to make the pressing frame 49 move upward and reset, thereby making the connecting rod 47 move to the left and reset, and then the first spring 42 rebounds, so that the third butt joint pipe 43 moves to the left and respectively docks with the first conducting pipe 301 and the second butt joint pipe 352 on the left, thereby making the first conducting pipe 301 and the second butt joint pipe 352 They are respectively connected with the adjacent second conducting pipe 311 and the first connecting pipe 351, so that the waste heat recovery boxes are interconnected to form a waste heat recovery device, so that multiple waste heat recovery boxes can be quickly and conveniently spliced ​​and combined, and then the waste water discharge pipe is connected with the second conducting pipe 311 on the far left, and then the clean water pipe is connected with the first connecting pipe 351 on the far left, so that the waste water enters the leftmost waste heat recovery box, and the clean water enters the heat absorption pipe 35 in the leftmost waste heat recovery box, so that the heat in the waste water is converted into the clean water to heat the clean water. When the waste water flows in the waste heat recovery box, the baffle 34 on the mounting plate 33 guides the waste water, so that the waste water flows upward between the baffles 34, thereby slowing down the flow rate of the waste water and making the waste water and the heat absorption pipe 35 The tube 35 is fully in contact, and the fin 36 is used to improve the heat exchange efficiency. After the wastewater flows to the wastewater tank, it enters the right side of the mounting plate 33, and then flows downward along the baffle 34 on the right side of the mounting plate 33. After that, the wastewater flows into the next waste heat recovery box through the first conducting pipe 301, and the clean water flows into the heat absorption pipe 35 in the next waste heat recovery box through the second butt joint 352 for heat exchange again until the heat in the wastewater is completely absorbed. When it is necessary to clean the inside of the waste heat recovery box, remove the second bolt 46 to separate the first clamping piece 44 and the second clamping piece 45, so that the second conducting pipe 311 and the first butt joint 351 can be separated from the second mounting frame 31, and then remove the first bolt 32 to separate the first mounting frame 30 from the second mounting frame 31.This allows the waste heat recovery box to be disassembled to facilitate thorough cleaning of the internal heat exchange tubes.

[0045] like Figure 1 , Figure 2 , Fig.12 , Fig.13 and Fig.14 As shown, it also includes a descaling and feeding mechanism 5, which includes a feeding pipe 50, an installation sleeve 51, a retaining piece 511, a conducting piece 52, a sliding plug 53, a third spring 54 and a fourth docking pipe 55. The feeding pipe 50 is connected to the left side of the upper part of the second installation frame 31, the rear side of the feeding pipe 50 is connected to the installation sleeve 51, the rear side of the installation sleeve 51 is connected to the retaining piece 511, the inner side of the rear part of the installation sleeve 51 is connected to the conducting piece 52, the sliding plug 53 is slidably connected to the conducting piece 52, the third spring 54 is connected between the sliding plug 53 and the connected conducting piece 52, the rear part of the installation sleeve 51 is clamped with the fourth docking pipe 55, the fourth docking pipe 55 is squeezed and matched with the adjacent sliding plug 53, the fourth docking pipe 55 is clamped and matched with the adjacent retaining piece 511, and the third spring 54 is in a compressed state.

[0046] By using the descaling and feeding mechanism 5 of the present device, the descaling agent can be conveniently added into the waste heat recovery box. The descaling agent is passed into the fourth butt joint pipe 55, so that the descaling agent enters the installation sleeve 51 through the fourth butt joint pipe 55, and then enters the waste heat recovery box from the feeding pipe 50 to descale the inside. After the descaling agent is added, the fourth butt joint pipe 55 is rotated to align the fourth butt joint pipe 55 with the locking member 511, and then the fourth butt joint pipe 55 is pulled out of the locking member 511, and then the third spring 54 rebounds, pushing the sliding plug 53 to move backward, so that the sliding plug 53 blocks the conducting member 52, and then blocks the installation sleeve 51, thereby playing a role in facilitating the addition of the descaling agent into the waste heat recovery box and facilitating the control of the amount of descaling agent added.

[0047] like Figure 1 , Figure 2 , Fig.15 and Fig.16As shown, it also includes a positioning locking mechanism 6, which includes a mounting frame 60, a guide column 61, a limit plate 62, a pressing plate 63, a fourth spring 631, a fifth spring 64 and an embedding piece 65. The front side of the mounting seat 1 is connected to the mounting frame 60, the upper right side of the mounting frame 60 is rotatably connected to the guide column 61, the guide column 61 is provided with an N-shaped groove, the lower part of the guide column 61 is connected to the limit plate 62, the left part of the mounting frame 60 is slidably connected to the pressing plate 63, the pressing plate 63 is connected to the connected mounting frame 60 with a fourth spring 631, the right part of the pressing plate 63 is slidably connected to the left and right embedding pieces 65, the embedding pieces 65 are connected to the connected pressing plate 63 with a fifth spring 64, the embedding pieces 65 are contacted and matched with the adjacent guide column 61 through the N-shaped groove, and the pressing frame 49 is squeezed and matched with the adjacent pressing plate 63.

[0048] The use of the alignment locking mechanism 6 of the present device can enhance the stability between the mounting seats 1. When the pressing frame 49 moves downward, the pressing plate 63 is squeezed to move downward, and the fourth spring 631 is squeezed and contracted. When the pressing plate 63 moves downward, it drives the embedding piece 65 to move downward. Through the action of the fifth spring 64, the embedding piece 65 always keeps in contact with the guide column 61, so that the embedding piece 65 moves downward along the vertical part of the N-shaped groove. At this time, the guide column 61 is not triggered to rotate. After the pressing frame 49 is reset, the fourth spring 631 rebounds, so that the pressing plate 63 is reset, and the embedding piece 65 is driven to move upward, so that the embedding piece 65 moves upward along the oblique part of the N-shaped groove, triggering the guide column 61 to rotate, and driving the limit plate 62 to rotate, so that the limit plate 62 rotates to the upper side of the other mounting frame 60, thereby being able to lock the mounting seat 1 in position and ensure the stability between the mounting seats 1.

[0049] like Figure 1 , Figure 2 and Fig.17 As shown, it also includes a limiting mechanism 7, which includes a rotating limiting frame 70, and the lower side of the middle part of the pressing frame 49 is rotatably connected to the rotating limiting frame 70.

[0050] By using the limiting mechanism 7 of the present device, the pressing frame 49 can be limited. After the pressing frame 49 moves upward and resets, the rotating limiting frame 70 is rotated and adjusted so that the lower side of the rotating limiting frame 70 contacts the upper side of the adjacent second mounting frame 31, thereby limiting the pressing frame 49 and avoiding accidental touching of the pressing frame 49.

[0051] like Figure 1 , Figure 2 and Fig.17 As shown, a shock absorbing mechanism 8 is also included. The shock absorbing mechanism 8 includes a rubber pad 80. The lower side of the mounting seat 1 is connected to the rubber pad 80, and the rubber pad 80 is connected to the adjacent alignment plate 2.

[0052] The shock absorbing mechanism 8 of the device can reduce the vibration of the mounting base 1. When water flows inside the waste heat recovery box, the waste heat recovery box will vibrate, driving the mounting base 1 to vibrate. When the mounting base 1 is placed on the ground, the rubber pad 80 is in contact with the ground, so that the rubber pad 80 can absorb the vibration of the mounting base 1, thereby reducing the vibration of the waste heat recovery box and preventing waste water leakage.

[0053] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
