[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-4 In this embodiment of the invention, a waste liquid recovery device with odor removal function includes an intermediate tank 1, a second side tank 12 on one side of the intermediate tank 1, and a first side tank 2 on the other side of the intermediate tank 1. The upper end of the intermediate tank 1 has a liquid inlet 7. A conical filter box 8 is slidably connected to the upper end of the intermediate tank 1. The lower end of the conical filter box 8 has a discharge assembly for conveying impurities to the second side tank 12. The discharge assembly includes a discharge pipe 11, which is connected to the middle of the lower end of the conical filter box 8. A solenoid valve 9 is provided at the upper end of the discharge pipe 11. An avoidance opening is provided on the partition between the intermediate box 1 and the second side box 12. The bottom of the discharge pipe 11 passes through the avoidance opening and is placed inside the second side box 12. A flexible pad 13 is provided in the gap between the avoidance opening and the discharge pipe 11. A liquid level sensor 6 is provided on one side of the upper end of the conical filter box 8. The liquid level sensor 6 can detect whether the drainage of the conical filter box 8 is unobstructed. When too many impurities accumulate inside the conical filter box 8, the liquid level inside the conical filter box 8 will rise accordingly. When the liquid level sensor 6 detects the liquid level, the solenoid valve 9 opens to discharge the impurities from the discharge pipe 11.

[0028] The lower end of the intermediate box 1 is also provided with a shaking assembly for driving the conical filter box 8 to shake up and down; the shaking assembly includes a pressure roller 37, which is installed at the lower end of the impurity discharge pipe 11. Inside the intermediate box 1, below the pressure roller 37, a mounting shaft 29 is rotatably connected. An eccentric wheel 30 that cooperates with the pressure roller 37 is fixedly connected to the mounting shaft 29. Tension springs 22 are connected to both sides inside the intermediate box 1, and the upper end of the tension springs 22 is fixedly connected to the conical filter box 8. During operation, the mounting shaft 29 drives the eccentric wheel 30 to rotate. The rotation of the eccentric wheel 30 drives the pressure roller 37 to move up and down. The up and down movement of the eccentric wheel 30 can drive the conical filter box 8 to shake up and down in cooperation with the tension springs 22, thereby promoting the discharge of impurities from the impurity discharge pipe 11.

[0029] An inclined plate 16 is fixedly connected to the lower end of the intermediate box 1. A permeable membrane 18 is provided at the lower end of the partition between the intermediate box 1 and the first side box 2. An extrusion assembly for extruding waste liquid into the cavity below the inclined plate 16 is provided on the inclined plate 16. The extrusion assembly includes an extrusion cylinder 17, which is fixedly connected to the bottom of the inclined plate 16. A piston rod 34 is slidably connected inside the extrusion cylinder 17. An outlet pipe 31 is provided at the bottom of the extrusion cylinder 17, and an outlet one-way valve is provided inside the outlet pipe 31. The lower end of the outlet pipe 31 extends out of the inclined plate 16. A suction pipe 33 is provided at the lower end of one side of the extrusion cylinder 17. The intermediate chamber 1 is equipped with a liquid inlet check valve. Inside the intermediate chamber 1, a crankshaft 26 is located above the piston rod 34. A connecting rod 35 is rotatably connected to the crankshaft 26, and the lower end of the connecting rod 35 is rotatably connected to the upper end of the piston rod 34. During operation, the crankshaft 26 drives the connecting rod 35 to move, and the movement of the connecting rod 35 drives the piston rod 34 to move up and down. The up and down movement of the piston rod 34 can drive the internal piston to move, so that liquid is drawn from the liquid suction pipe 33 and then discharged from the liquid outlet pipe 31 into the cavity below the inclined plate 16. This allows the cavity below the inclined plate 16 to have a certain pressure, thereby promoting the permeation efficiency of the permeation membrane 18.

[0030] The intermediate housing 1 is equipped with a drive assembly for driving the extrusion assembly and the vibration assembly. The drive assembly includes a second gear 28, which is mounted on one end of the crankshaft 26, extending out of the intermediate housing 1. An end shaft 39 is mounted on the intermediate housing 1 using a bracket. The end shaft 39 is concentrically arranged with the mounting shaft 29. An electromagnetic clutch 38 is installed between the end shaft 39 and the mounting shaft 29. Pulleys 32 are installed at the ends of both the end shaft 39 and the mounting shaft 29, and a belt 40 is installed between the two pulleys 32. A second motor 27 is also installed on one side of the intermediate housing 1. The output end of the second motor 27 is equipped with a first motor gear, which meshes with the second gear 28. During operation, the second motor 27 drives the second gear 28 to rotate. The rotation of the second gear 28 drives the crankshaft 26 to rotate. The rotation of the crankshaft 26 also drives the pulleys 32 and the belt 40 to rotate, which in turn drives the end shaft 39 to rotate. When the electromagnetic clutch 38 is engaged, it can also drive the mounting shaft 29 to rotate.

[0031] The second side chamber 12 is provided with a draining assembly for draining the filtered impurities in the middle. The draining assembly includes a filter plate 14, which is located in the middle of the second side chamber 12. A guide plate 15 is provided inside the second side chamber 12 below the filter plate 14. A drain outlet communicating with the intermediate chamber 1 is provided in the second side chamber 12 between the guide plate 15 and the filter plate 14. A cleaning door for cleaning impurities is provided on one side of the second side chamber 12. The filtered impurities can be further filtered through the filter plate 14, and the filtered water enters the interior of the intermediate chamber 1 along the guide plate 15.

[0032] The second side box 12 is also equipped with an odor treatment component for removing odors from waste liquid. The odor treatment component includes an exhaust fan 10, which is installed at the upper end of the second side box 12. The exhaust fan 10 has a branch pipe at its suction end, which is connected to the upper end of the intermediate box 1. The exhaust fan 10 has an exhaust pipe at its output end, which is connected to the cavity of the second side box 12 located below the guide plate 15. Several activated carbon adsorption plates 21 are detachably connected to the cavity of the second side box 12 located below the guide plate 15. An exhaust port 19 is opened on one side of the second side box 12 located below the activated carbon adsorption plates 21. When working, the exhaust fan 10 is activated to draw in air from the upper end of the intermediate box 1, thereby drawing in air containing odors. After being drawn in, the air is discharged into the cavity at the lower end of the second side box 12. The odors are removed by the activated carbon adsorption plates 21 layer by layer before being discharged.

[0033] The first side box 2 has connecting pipes 23 at both the upper and lower ends of one side, and each connecting pipe 23 is equipped with a switch valve 24. The lower end of the intermediate box 1 is also equipped with a slag discharge port 20, which is equipped with a discharge valve. The first side box 2 is also equipped with a backwashing assembly for backwashing the permeate membrane 18. The backwashing assembly includes a threaded sleeve 36, which is rotatably connected to the middle position of the upper end of the first side box 2. A threaded rod 5 is threadedly connected to the inner end of the threaded sleeve 36, and a piston disc 3 is fixedly connected to the lower end of the threaded rod 5. The piston disc 3 is slidably connected to the inner wall of the first side box 2. The upper end of the crankshaft 26 is fixedly connected to a first gear 4. A gear is installed on the upper end of one side of the intermediate box 1. The first motor 25 has a second motor gear at its output end, which meshes with the first gear 4. When backwashing the permeate membrane 18 is required, the first side box 2 is filled with water, then the switch valve 24 is closed, and then the discharge valve on 20 is opened. At the same time, the first motor 25 drives the first gear 4 to rotate, which in turn drives the threaded sleeve 36 to rotate. The threaded sleeve 36 cooperates with the threaded rod 5, which in turn drives the piston disc 3 to move. The piston disc 3 moves and pushes the water downward. At this time, the water will permeate through the permeate membrane 18 into the intermediate box 1, thereby achieving backwashing of the permeate membrane 18. The impurities washed down can be discharged through the slag discharge port 20.

[0034] The working principle of this invention is as follows: During operation, waste liquid is introduced through the inlet 7 and filtered through the conical filter box 8. Impurities remain inside the conical filter box 8, while the liquid phase is discharged. Simultaneously, the crankshaft 26 drives the connecting rod 35 to move, which in turn drives the piston rod 34 to move up and down. The up-and-down movement of the piston rod 34 drives the internal piston to move, drawing liquid from the suction pipe 33 and discharging it from the outlet pipe 31 into the cavity below the inclined plate 16. This creates a certain pressure in the cavity below the inclined plate 16, thereby promoting the permeation efficiency of the permeation membrane 18. The permeated water is discharged through the connecting pipe 23 for recycling. The liquid level sensor 6 can detect whether the drainage of the conical filter box 8 is unobstructed. When too many impurities accumulate inside the conical filter box 8, the liquid level sensor 6 will detect the flow rate of the liquid. As the liquid level rises, when the liquid level sensor 6 detects the liquid level, the solenoid valve 9 opens to discharge impurities from the discharge pipe 11. At the same time as the solenoid valve 9 opens, the electromagnetic clutch 38 operates synchronously to connect the end shaft 39 and the mounting shaft 29 to transmit power. The mounting shaft 29 drives the eccentric wheel 30 to rotate. The rotation of the eccentric wheel 30 drives the pressure roller 37 to move up and down. The up and down movement of the eccentric wheel 30 can drive the conical filter box 8 to shake up and down in conjunction with the tension spring 22, thereby promoting the discharge of impurities from the discharge pipe 11. While treating the waste liquid, the exhaust fan 10 starts to draw in the air at the top of the intermediate box 1, thereby drawing in the air containing odors. After being drawn in, the air is discharged into the cavity at the bottom of the second side box 12, where it is adsorbed layer by layer by the activated carbon adsorption plate 21 to remove the odors before being discharged.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.

The waste liquid will be filtered through the conical filter box (8). Impurities remain in the conical filter box (8), while the liquid phase is discharged. At the same time, the crankshaft (26) drives the connecting rod (35) to move. The movement of the connecting rod (35) drives the piston rod (34) to move up and down. The up and down movement of the piston rod (34) can drive the internal piston to move, so that liquid is drawn from the inside of the suction pipe (33) and then discharged from the outlet pipe (31) into the cavity below the inclined plate (16), so that the cavity below the inclined plate (16) can have a certain pressure, thereby promoting the permeation efficiency of the permeation membrane (18).

When the liquid level sensor (6) detects the liquid level, the solenoid valve (9) opens to discharge the impurities from the discharge pipe (11). At the same time as the solenoid valve (9) opens, the electromagnetic clutch (38) moves synchronously to connect the end shaft (39) and the mounting shaft (29) to transmit power. The mounting shaft (29) drives the eccentric wheel (30) to rotate. The eccentric wheel (30) rotates, driving the pressure wheel (37) to move up and down. The up and down movement of the eccentric wheel (30) can drive the conical filter box (8) to shake up and down in conjunction with the tension spring (22), thereby promoting the discharge of impurities from the discharge pipe (11). While treating the waste liquid, the blower (10) is started to draw in the air at the top of the intermediate box (1), thereby drawing in the air containing odors. After being drawn in, the air is discharged into the cavity at the bottom of the second side box (12), where it is adsorbed layer by layer by the activated carbon adsorption plate (21) to remove the odors before being discharged.
