[0002] Wastewater heat recovery machine is a kind of equipment used to recover heat energy from wastewater to supply other processes or heating systems. Its main function is to convert the heat in the wastewater into usable energy, improve energy utilization efficiency, and reduce energy consumption. Setting up an interception net to intercept the residue in the wastewater can effectively prevent the residue from entering the recovery machine, blocking the pipes or damaging the equipment, protecting the normal operation of the recovery machine, and reducing subsequent cleaning and maintenance work.

[0003] In the prior art, most interception nets are directly fixed inside the pipeline of the wastewater heat recovery machine. After being cleaned for a period of time, the interception net of the wastewater heat recovery machine will gradually become clogged. On the one hand, the wastewater flow rate of the wastewater heat recovery machine will be reduced, affecting the heat exchange efficiency. On the other hand, the interception net intercepts residues randomly inside the wastewater pipe, resulting in a more time-consuming cleaning process for the waste residues. Summary of the invention

[0004] The purpose of the utility model is to solve the problem that in the prior art, most of the interception nets are directly fixed inside the pipeline of the wastewater heat recovery machine. After the interception net of the wastewater heat recovery machine has been cleaned for a period of time, the interception net will gradually become clogged. On the one hand, the wastewater flow rate of the wastewater heat recovery machine will be reduced, affecting the heat exchange efficiency. On the other hand, the interception net intercepts the residues randomly inside the wastewater pipe, resulting in a relatively time-consuming cleaning process of the waste residues. A wastewater heat recovery machine that is easy to remove the residues is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The top of the heat exchange U-tube 3 is fixedly connected to one end of a horizontal tube 8, and the other end of the horizontal tube 8 is fixedly connected to a storage tube 5. A water inlet pipe 7 is arranged at the bottom of a side of the storage tube 5 away from the horizontal tube 8. The water inlet pipe 7 is used to introduce wastewater into the heat exchange box 1.

[0021] An interception mesh plate 6 is fixedly installed in the inner cavity of the storage cylinder 5 at an angle below one end of the horizontal tube 8. A dredging and releasing component is arranged on the top of the interception mesh plate 6 for quickly dredging the mesh holes of the interception mesh plate 6 and releasing residues. AC pipes 2 are equidistantly arranged on the side of the heat exchanger box 1 in the vertical direction. A valve is arranged on the top of the AC pipe 2 near one end of the heat exchanger box 1, and cooling water is added to the heat exchanger box 1 through the AC pipe 2.

[0022] The dredging release component includes a common plate 4, a central column 10, and a stepped cover 11. Dredging columns 41 are evenly distributed on the bottom of the common plate 4. The positions of the dredging columns 41 correspond one-to-one to the positions of the mesh holes of the intercepting mesh plate 6. The dredging columns 41 are used to dredge the mesh holes of the intercepting mesh plate 6.

[0023] The center position of the bottom of the common plate 4 is fixedly connected to the top of the center column 10, and the bottom of the center column 10 is rotatably connected to the center of the top of the step cover 11. The step cover 11 includes a wide section and a narrow section. A rotating handle 110 is fixedly arranged at the center of the bottom of the step cover 11. The narrow section of the step cover 11 is threaded into the bottom of the storage tube 5. A limiting rod 12 is fixedly arranged in the middle position of the outer wall of the center column 10.
