[0031] The difference between this embodiment and Embodiment 1 lies in: Specifically, the extrusion and recovery assembly 7 includes an electric push rod 71, an extrusion plate 72, a drain pipe 73, a fine filter screen 74, and a corrugated plate 75. Among them, an electric push rod 71 is arranged on one side of the sundries pipe 5, the output end of the electric push rod 71 is provided with an extrusion plate 72, a corrugated plate 75 is arranged on one side at the bottom end of the sundries pipe 5, a fine filter screen 74 is arranged at the trough of the corrugated plate 75, and a drain pipe 73 is arranged at the bottom end of the treatment tank 3 corresponding to the corrugated plate 75.

[0032] By adopting the above technical solution, the sundries entering the interior of the sundries pipe 5 are broken by the crushing mechanism 6 and then fall on the surface of the corrugated plate 75. At this time, the sewage carried by the sundries leaks through the fine filter screen 74, and the sewage will impact the crushed sundries to make them move downward along the corrugated plate 75. When the sundries reach the bottom end of the extrusion plate 72, the electric push rod 71 is started to extrude and drain the sundries, ensuring the recovery effect of the sewage, guaranteeing the treatment quality of the sewage, and improving the convenience of subsequent treatment of the sundries.

[0033] Specifically, the bottom end of the extrusion plate 72 is arranged in a wave shape, and a one-way valve is arranged at one end of the drain pipe 73.

[0034] By adopting the above technical solution, the fitting effect between the extrusion plate 72 and the corrugated plate 75 during use is ensured, and the extrusion strength of the sundries is guaranteed.

At this time, the sewage carried by the sundries leaks through the fine filter screen 74, and the sewage will impact the crushed sundries to make them move downward along the corrugated plate 75. When the sundries reach the bottom end of the extrusion plate 72, the electric push rod 71 is started to extrude and drain the sundries, ensuring the recovery effect of the sewage, guaranteeing the treatment quality of the sewage, and improving the convenience of subsequent treatment of the sundries.

[0036] The structures and operating principles of the crushing mechanism 6, the grading filter plate 8, and the primary filter plate 9 in the present utility model have been disclosed in a sewage source heat pump heating sewage pretreatment mechanism with Chinese patent application number 202222229449.8.

[0037] Working principle and usage process of the utility model: When the utility model is in use, when using the sewage pretreatment mechanism of the sewage source heat pump for heating, sewage is introduced into the treatment tank 3 from the water inlet pipe 2, and at the same time, the stepping motor 14 is started to drive the driving wheel 12 to rotate. At this time, the driving wheel 12 drives the transmission chain 11 and the connecting plate 17 at its upper end to rotate. When the connecting plate 17 rotates to the lower part of the transmission chain 11, the sundries on the surface of the partition plate 4 are scraped and cleaned by the scraper 18, and the sundries fall into the sundries pipe 5 from bottom to top for treatment. When it is necessary to adjust the use length of the scraper 18, loosen the positioning bolt 16 and slide the scraper 18 along the inside of the connecting plate 17, and then tighten the positioning bolt 16 after determining the use height;

[0038] When it is necessary to disassemble the damaged connecting plate 17 and scraper 18, press two groups of hooks 153 at the same time to make them slide along the hooks 153, and make the limit spring 151 be compressed under force.
