Flue gas is the main way for general energy-consuming equipment to waste energy. The energy-saving waste heat recovery machine realizes the purpose of energy conservation and emission reduction by converting the heat carried by the flue gas into usable heat;

[0003] When the energy-saving waste heat recovery machine converts the heat carried by the flue gas into usable heat through heat exchange, the flue gas often contains components such as sulfur dioxide, which will corrode the tube sheet and weld when encountering steam or moisture, resulting in leakage at the tube sheet or weld. It is necessary to regularly maintain the energy-saving waste heat recovery machine. The cabinet board in the energy-saving waste heat recovery machine is installed through multiple bolts. When maintaining, it takes a long time to remove the entire cabinet board. To prevent the cabinet board from slipping and bumping and deforming, it is difficult to install it with the energy-saving waste heat recovery machine. It is necessary to properly place the cabinet door of the energy-saving waste heat recovery machine, so that it takes a long time to remove and place the cabinet door of the energy-saving waste heat recovery machine. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-7 The utility model provides a technical solution: an energy-saving waste heat recovery machine that can be regularly maintained, including a recovery machine main body 1 and a folding plate mechanism 2. An inlet flow pipe 12 and an outlet flow pipe 13 are installed inside the recovery machine main body 1. Folding plate mechanisms 2 are arranged in the through grooves on both sides of the recovery machine main body 1, and the folding plate mechanism 2 includes a first connecting plate 21, a docking plate 22, a second connecting plate 23, a card slot 24 and a clamping block 25. The first connecting plate 21, the docking plate 22 and the second connecting plate 23 are sequentially arranged in the through grooves on both sides of the recovery machine main body 1. Card slots 24 are opened on the upper side of the first connecting plate 21, both sides of the docking plate 22 and the lower side of the second connecting plate 23. The card slot 24 is movably docked with the clamping block 25. The lower side of the first connecting plate 21 is movably connected to the recovery machine main body 1 through a hinge. A limiting bolt 3 penetrates through the upper end of the second connecting plate 23. A connecting spring 4 is sleeved between the limiting bolt 3 and the second connecting plate 23. One end of the connecting spring 4 is movably connected to the limiting bolt 3 through a bearing, and the other end of the connecting spring 4 is fixed to the second connecting plate 23. Docking blocks 5 are respectively fixed on both sides of the first connecting plate 21, both sides of the docking plate 22 and both sides of the second connecting plate 23. Docking grooves 7 are respectively opened on both sides of the recovery machine main body 1 close to the first connecting plate 21, the docking plate 22 and the second connecting plate 23. A connecting pad 6 is connected to the outside of the docking block 5, and the docking block 5 is docked with the docking groove 7. The clamping block 25 matches the card slot 24. The limiting bolt 3 is threadedly connected to the recovery machine main body 1. The connecting pad 6 is made of rubber material, and the connecting pad 6 is in interference fit with the docking groove 7.

[0026] The energy-saving waste heat recovery machine converts the heat carried by the flue gas into available heat through heat exchange. The low-temperature fluid enters the inside of the recovery machine main body 1 through the inlet flow pipe 12, so that the low-temperature fluid and the high-temperature flue gas inside the recovery machine main body 1 perform "cross-countercurrent" heat exchange on both sides of the plate. After the low-temperature fluid is exchanged, it is discharged through the outlet flow pipe 13. When the energy-saving waste heat recovery machine is in use, the cabinet plate needs to be opened for regular maintenance. When the energy-saving waste heat recovery machine is maintained, first rotate the limiting bolt 3. Since the limiting bolt 3 is threadedly connected to the recovery machine main body 1, the limiting bolt 3 is disengaged from the recovery machine main body 1. Through the connected connecting spring 4, the limiting bolt 3 will not be disengaged from the second connecting plate 23, so that the limiting bolt 3 will not be lost after being disengaged from the recovery machine main body 1. Then, pull the second connecting plate 23, the docking plate 22 and the first connecting plate 21 outwards in sequence, so that the docking block 5 is disengaged from the docking groove 7. Through the sliding docking of the clamping block 25 and the card slot 24, when the second connecting plate 23, the docking plate 22 and the first connecting plate 21 are pulled outwards, they can be rotated and folded and contracted in sequence, so that the first connecting plate 21, the docking plate 22 and the second connecting plate 23 are received on both sides of the recovery machine main body 1, and both sides of the recovery machine main body 1 are opened, so that the recovery machine main body 1 can quickly expose the through grooves on both sides;

[0027] When the maintenance is completed, the first connecting plate 21, the docking plate 22, and the second connecting plate 23 are successively docked with both sides of the main body 1 of the recycling machine. Press the docking blocks 5 of the first connecting plate 21, the docking blocks 5 of the docking plate 22, and the docking blocks 5 of the second connecting plate 23 in sequence. Through the interference fit between the connecting pad 6 and the docking groove 7, when the docking block 5 is docked with the docking groove 7, the docking block 5 is restricted inside the docking groove 7, so that the first connecting plate 21, the docking plate 22, and the second connecting plate 23 are temporarily restricted on both sides of the main body 1 of the recycling machine, facilitating the rotation of the limit bolt 3. Rotate the limit bolt 3 so that the first connecting plate 21, the docking plate 22, and the second connecting plate 23 are re-restricted on both sides of the main body 1 of the recycling machine. By rotating and folding the first connecting plate 21, the docking plate 22, and the second connecting plate 23 together, both sides of the main body 1 of the recycling machine can be quickly opened, making it convenient for the energy-saving waste heat recovery machine to be regularly maintained.

[0028] One side of the main body 1 of the recycling machine is fixed to one end of the connecting rope 8, and the other end of the connecting rope 8 is connected to the first magnetic block 9. A second magnetic block 10 is fixed on the side of the main body 1 of the recycling machine close to the first magnetic block 9. A third magnetic block 11 is connected to the outside of the second connecting plate 23. The first magnetic block 9 and the second magnetic block 10 are magnetically attracted, and the first magnetic block 9 and the third magnetic block 11 are magnetically attracted.

[0029] When the energy-saving waste heat recovery machine is regularly maintained, after folding and storing the first connecting plate 21, the docking plate 22, and the second connecting plate 23, through the magnetic attraction between the first magnetic block 9 and the second magnetic block 10, the first magnetic block 9 and the second magnetic block 10 are restricted together, so that the connecting rope 8 is restricted on both sides of the main body 1 of the recycling machine and will not swing randomly. Pull the first magnetic block 9 to separate the first magnetic block 9 from the second magnetic block 10, and then attach the first magnetic block 9 to the third magnetic block 11. Through the magnetic attraction between the first magnetic block 9 and the third magnetic block 11, the first magnetic block 9 and the third magnetic block 11 are restricted together, so that the connecting rope 8 and the second connecting plate 23 are restricted together. Through the limitation of the connecting rope 8 and the second connecting plate 23, the first connecting plate 21, the docking plate 22, and the second connecting plate 23 will not spread out after being folded and stored, and the first connecting plate 21, the docking plate 22, and the second connecting plate 23 on both sides of the energy-saving waste heat recovery machine will not spread out randomly after being folded and stored, causing damage and deformation.

[0030] In summary, the energy-saving waste heat recovery machine converts the heat carried by the flue gas into utilizable heat through heat exchange. When the energy-saving waste heat recovery machine is in use, the cabinet panel needs to be opened regularly for maintenance. When the energy-saving waste heat recovery machine is being maintained, first rotate the limit bolt 3, and then pull out the second connecting plate 23, the docking plate 22, and the first connecting plate 21 in sequence, and perform rotational folding and contraction in sequence to open both sides of the recovery machine main body 1, so that the energy-saving waste heat recovery machine is convenient for regular maintenance. When the energy-saving waste heat recovery machine is being regularly maintained, after folding and storing the first connecting plate 21, the docking plate 22, and the second connecting plate 23, pull the first magnetic block 9 to separate the first magnetic block 9 from the second magnetic block 10, and then fit the first magnetic block 9 with the third magnetic block 11 to limit the connecting rope 8 together with the second connecting plate 23. Through the limitation of the connecting rope 8 and the second connecting plate 23, the first connecting plate 21, the docking plate 22, and the second connecting plate 23 will not spread out after being folded and stored, so that the first connecting plate 21, the docking plate 22, and the second connecting plate 23 on both sides of the energy-saving waste heat recovery machine will not spread out randomly after being folded and stored, causing damage and deformation. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
