[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. In the process of converting hot fluid into cold fluid, a large amount of waste heat will be generated. In order to meet the requirements of energy conservation and emission reduction, ceramic plates are currently installed between the plates of the heat exchanger to absorb the waste heat for recycling.

[0003] For example, a Chinese patent document with publication number CN219223434U discloses a plate-type waste heat recovery heat exchanger, including a heat exchanger body, plates, a load-bearing plate, a fixing frame, and a flange. An adjusting device is provided on the inner wall of the heat exchanger body. The adjusting device includes a fixing frame, which is fixedly connected to the heat exchanger body. One end of the fixing frame is fixedly connected to a limiting block. A limiting hole is provided in the limiting block corresponding to the position of the heat exchanger body. The inner wall of the limiting hole is clamped with the limiting block. Two telescopic rods are fixedly connected to one end of the fixing frame away from the limiting block, and springs are sleeved on the arc surfaces of the two telescopic rods.

[0004] It can be seen from the above disclosed content that in the above technical solution, by squeezing the spring, the fixing frame can be squeezed and fixed in the fixing frame, so that multiple ceramic plates can be installed, so as to recycle the waste heat over a large area and improve the efficiency of waste heat recycling.

[0005] However, in the process of completing the fixing frame, the spring is squeezed so that the fixing frame is subjected to positive pressure from the spring, and then the fixing frame is subjected to a large amount of friction when being pushed into or pushed out of the fixing frame, which makes it very inconvenient to disassemble and assemble the fixing frame. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an energy recovery device for a heat exchanger, which can facilitate the installation of a fixing frame.

[0008] The utility model is further configured as follows: a mounting groove is provided on the fixing frame, the mounting device includes a mounting seat adapted to the mounting groove, the mounting seat is fixed to the mounting groove, a sliding groove adapted to the fixing frame is provided on the mounting seat, the bottom of the mounting seat extends outward from the mounting groove as an extension end, a twist knob which can form a threaded fit with the extension end is mounted on the extension end, a locking rod extending toward the sliding groove is provided at the center of the twist knob, and the locking rod is rotated by the twist knob to move closer to or away from the lock hole.

[0009] The utility model is further configured as follows: an installation flange is provided on the inner wall of the extension end, a limit spring is fixed on the installation flange, and a pressing flange is provided on the side of the locking rod facing the twisting direction to form an outward offset.

[0010] The utility model is further configured as follows: guide grooves are provided on both sides of the fixing frame, and the guide grooves are opposite to the sliding grooves.

[0011] The utility model is further configured as follows: a first positioning groove is provided at the center of the fixing frame, and a second positioning groove which can be opposite to the first positioning groove is provided on the mounting seat.

[0012] The utility model is further configured as follows: a first threaded hole is symmetrically arranged in the installation groove, and second threaded holes opposite to the first threaded holes are arranged on both sides of the slide groove, and the second threaded hole is fixed to the first threaded hole by a locking member.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The present solution improves the locking structure. When the fixing frame is installed in the installation area, the installation device will not apply positive pressure to the fixing frame, thereby reducing the friction force to which the fixing frame is subjected when sliding into the installation area.

[0022] like Figures 1 to 5 As shown, the utility model discloses an energy recovery device of a heat exchanger, including a heat exchanger body 1 and a fixing frame 2, a plate 3 is connected to the fixing frame 2, the plate 3 is multiple and spaced apart from each other, an installation area is formed between adjacent plates 3, a fixing frame 4 is provided in the installation area, a bearing groove 41 is provided on the inner side of the fixing frame 4, a ceramic block 5 adapted to the bearing groove 41 is provided in the bearing groove 41, a locking hole 42 is provided at the bottom of the fixing frame 4, an installation device is provided in the installation area, the installation device cooperates with the locking hole 42 to realize rapid locking of the fixing frame 4, and the locking structure is improved in this scheme, when the fixing frame 4 is installed in the installation area, the installation device will not apply positive pressure to the fixing frame 4, so that the friction force on the fixing frame 4 when sliding into the installation area can be reduced, so that the installation of the fixing frame 4 can be facilitated;

[0023] The principle that the mounting device does not apply positive pressure to the fixing frame 4 during the process of pushing the fixing frame 4 into the fixing frame 2 or pushing it out from the fixing frame 2 is as follows: a mounting groove is provided on the fixing frame 2, and the mounting device includes a mounting seat 61 adapted to the mounting groove, the mounting seat 61 is fixed to the mounting groove, and a slide groove 611 adapted to the fixing frame 4 is provided on the mounting seat 61, and the bottom of the mounting seat 61 extends outward from the mounting groove as an extension end 62, and a twist 63 that can form a threaded fit with the extension end 62 is mounted on the extension end 62, and a locking rod 64 extending toward the slide groove 611 is provided at the center of the twist 63, and the locking rod 64 is rotated by the twist 63 to approach or move away from the locking hole 42, and when the fixing frame 4 is pushed into the fixing frame 2 or pushed out from the fixing frame 2, ... the locking rod 64 is rotated by the twist 63 to approach or move By rotating the knob 63, since the knob 63 and the extension end 62 form a threaded fit, the knob 63 can move along the extension end 62, thereby driving the locking rod 64 to move away from the locking hole 42. Therefore, with this locking structure, when the fixing frame 4 is pushed into the fixing frame 2 or pushed out from the fixing frame 2, no positive pressure is applied to the fixing frame 4, thereby reducing the friction force applied to the fixing frame 4 when it is pushed. When fixing the fixing frame 4, by reversing the knob 63, the locking rod 64 can be driven to approach the locking hole 42 until it is inserted into the locking hole 42, thereby limiting the position of the fixing frame 4, and the fixing frame 2 and the mounting seat 61 can respectively abut against the upper and lower sides of the fixing frame 4, thereby achieving stable fixation of the fixing frame 4.
