Description

Technical Field

[0001] This utility model relates to the field of absorption heat pump technology, specifically to a wastewater waste heat absorption heat pump. Background Technology

[0002] An absorption heat pump is a circulating system that utilizes a low-grade heat source to pump heat from a low-temperature heat source to a high-temperature heat source. It is an effective device for recovering and utilizing low-temperature heat energy, and has the dual functions of saving energy and protecting the environment. In wastewater treatment, waste heat absorption heat pumps are usually used to collect and utilize the wastewater's residual heat. However, the filter screen installed inside the inlet of the waste heat absorption heat pump is prone to clogging. When the filter screen is clogged, workers usually need to use hand tools to clean it, which is time-consuming and labor-intensive. Therefore, a wastewater waste heat absorption heat pump is proposed to facilitate filter screen cleaning. Utility Model Content

Two connecting rods 16 are welded and fixed on the side of the first baffle ring 12 away from the second filter screen 15. The ends of the two connecting rods 16 away from the first baffle ring 12 are welded and connected to the tub lid 7. A drain valve 17 is welded and fixed to the bottom of the outer tub 3.

[0026] When in use, open the inlet valve 5, and the wastewater enters the outer tank 3 through the inlet valve 5. The first filter screen 13 and the second filter screen 15 filter the wastewater. The filtered water enters the heat pump body 1. The output shaft of the motor 8 drives the crossbar 9 to rotate, and the locking block 10 and the cleaning brush 11 rotate accordingly. The cleaning brush 11 can clean the debris on the first filter screen 13. No manual cleaning is required, saving time and effort. Open the drain valve 17 to discharge the sewage in the outer tank 3.

[0027] To facilitate the replacement of the first filter 13 and the second filter 15, for example, as follows: Figure 3 As shown, two blocks 19 are welded and fixed to the outer wall of the outer barrel 3. Electric push rods 20 are fixed to the side walls of the two blocks 19 away from the heat pump body 1 by bolts. Connecting blocks 21 are fixed to the piston rods of the two electric push rods 20 by bolts. The two connecting blocks 21 are welded to the barrel cover 7.

[0028] When in use, the piston rods of the two electric push rods 20 drive the two connecting blocks 21 to move away from the heat pump body 1.

[0034] During installation, pass the bottom end of the bolt through the through holes at the four corners of the support 2 to make it easy to fix the support 2 to the ground.

[0035] When this utility model is in use, the inlet valve 5 is opened, and the wastewater enters the outer tank 3 through the inlet valve 5. The first filter screen 13 and the second filter screen 15 filter the wastewater. The filtered water enters the heat pump body 1. The output shaft of the motor 8 drives the crossbar 9 to rotate, and the locking block 10 and the cleaning brush 11 rotate accordingly. The cleaning brush 11 can clean the debris on the first filter screen 13 without the need for manual cleaning by workers, saving time and effort. The drain valve 17 is opened, and the sewage generated in the outer tank 3 during the cleaning of the first filter screen 13 is discharged into the collection container through the second telescopic pipe 18 for subsequent sewage treatment.

[0036] The piston rods of the two electric push rods 20 drive the two connecting blocks 21 to move away from the heat pump body 1. The bucket lid 7, motor 8, crossbar 9, cleaning brush 11 and first retaining ring 12 move away from the heat pump body 1 accordingly, making it convenient to remove and replace the first filter screen 13, the second retaining ring 14 and the second filter screen 15.
