Detailed Implementation

[0049] 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.

[0050] In the embodiments of this invention, please refer to Figures 1 to 8 A pharmaceutical wastewater treatment device includes a treatment chamber 1, and further includes:

[0051] The top of the filter chamber 3 is connected to the bottom of the treatment chamber 1 and communicates with its interior. A valve is installed inside the filter chamber 3.

[0052] Filter cone 4 is connected to the inner wall of filter chamber 3;

[0053] The liquid outlet 5 is connected to the bottom of the filter chamber 3 and communicates with its interior. A valve 2 is provided inside the liquid outlet 5.

[0054] The dosing mechanism 2, connected to the treatment chamber 1, is used to add liquid medicine into the treatment chamber 1. The dosing mechanism 2 includes: a material cylinder 21, located at the top of the treatment chamber 1, for storing the liquid medicine; a rotating base 22, rotatably connected to the bottom of the material cylinder 21; a reciprocating assembly 23, one end connected to the treatment chamber 1 and the other end connected to the material cylinder 21, for driving the material cylinder 21 to reciprocate linearly along the treatment chamber 1; a dosing and stirring assembly 24, one end connected to the treatment chamber 1 and the other end connected to the rotating base 22, for adding liquid medicine into the treatment chamber 1 and stirring; and a pressurizing assembly 25, connected to the dosing and stirring assembly 24, for increasing pressure during dosing.

[0055] The liquid medicine is pre-stored in the material cylinder 21. When the liquid medicine needs to be added, the reciprocating component 23 works, driving the material cylinder 21 to reciprocate in a straight line along the treatment chamber 1. During the movement of the material cylinder 21, the dosing and stirring component 24 drives the rotating base 22 to rotate. At the same time, the liquid medicine is added into the treatment chamber 1 through the dosing and stirring component 24. The pressurizing component 25 plays a role in this process, increasing the pressure when the liquid medicine is added, ensuring that the liquid medicine can be smoothly added into the treatment chamber 1.

[0056] After the wastewater is treated with chemicals in the treatment chamber 1, valve one in the filter chamber 3 is opened, and the wastewater enters the filter cone 4 through the filter chamber 3. The filter cone 4 plays a certain role in filtration and prevents large particles of impurities from clogging the outlet of the filter chamber 3. The filtered wastewater is discharged through the outlet 5. Valve two in the outlet 5 is used to control the discharge of wastewater.

[0057] As one embodiment of the present invention, please refer to Figures 1 to 5 The reciprocating component 23 includes:

[0058] The telescopic component 231 is connected at one end to the processing chamber 1;

[0059] The sliding block 232 is connected to the other end of the telescopic component 231 and is slidably connected to the processing chamber 1;

[0060] Fixed lever 233, one end of which is connected to sliding block 232;

[0061] The fixing block 234 is connected to the other end of the fixing folding rod 233 and to the material cylinder 21.

[0062] The telescopic component 231 drives the sliding block 232 to slide linearly along the processing chamber 1, and then drives the material cylinder 21 to reciprocate linearly along the processing chamber 1 through the fixed bending rod 233 and the fixed block 234. The telescopic component 231 can be an electric telescopic rod, a cylinder, etc.

[0063] As one embodiment of the present invention, please refer to Figures 1 to 7 The dosing and stirring assembly 24 includes:

[0064] The rotating assembly 241 is connected at one end to the processing chamber 1 and at the other end to the rotating chassis 22, and is used to drive the rotating chassis 22 to rotate.

[0065] The folded tube 242 is connected at one end to the rotating base 22 and communicates with the inside of the material cylinder 21. The folded tube 242 is provided in several groups and is arranged in a circumferential manner with equal spacing.

[0066] Rotating tube 243 is rotatably connected to folded tube 242 and communicates with its interior;

[0067] The dosing tube 244 is connected to the rotating tube 243 and communicates with its interior. The bottom of the dosing tube 244 has several sets of drug outlets, and the dosing tube 244 is equipped with a one-way valve.

[0068] The range adjustment component 245 is connected at one end to the rotating chassis 22 and at the other end to the dosing tube 244, and is used to adjust the dosing range of the dosing tube 244.

[0069] The material cylinder 21 reciprocates laterally, driving the rotating base 22 to move synchronously. The rotating component 241 drives the rotating base 22 to rotate. The rotating base 22 drives the dosing pipe 244 to revolve through the folding pipe 242 and the rotating pipe 243. The dosing pipe 244 drives the range adjustment component 245 to rotate. The range adjustment component 245 drives the dosing pipe 244 to move, thereby adjusting the dosing range. At the same time, the dosing pipe 244 stirs the liquid medicine and wastewater, improving the mixing effect.

[0070] As one embodiment of the present invention, please refer to Figures 1 to 5 The rotating assembly 241 includes:

[0071] Gear ring 2411 is connected to rotating base 22;

[0072] The toothed plate 2412 is connected to the processing chamber 1 and meshes with the toothed ring 2411.

[0073] The material cylinder 21 moves laterally and reciprocates, which drives the rotating base 22 to move laterally and reciprocate. The rotating base 22 drives the toothed ring 2411 to move laterally and reciprocate. Since the toothed ring 2411 meshes with the toothed plate 2412, the toothed ring 2411 rotates, which drives the rotating base 22 to rotate.

[0074] As one embodiment of the present invention, please refer to Figures 1 to 4 , Figure 6 and Figure 7 The range adjustment component 245 includes:

[0075] A threaded cylinder 2451 passes through and is rotatably connected to a rotating base 22, and the threaded cylinder 2451 is connected to a fixed block 234.

[0076] Threaded block 2452 is threadedly connected to threaded cylinder 2451;

[0077] The hinged support rod 2453 is hinged at one end to the threaded block 2452 and at the other end to the dosing tube 244.

[0078] The rotating chassis 22 drives the dosing pipe 244 to revolve, which in turn drives the hinged support rod 2453 to revolve synchronously. The hinged support rod 2453 drives the threaded block 2452 to rotate. Since the threaded block 2452 is threadedly connected to the threaded cylinder 2451, the threaded block 2452 reciprocates longitudinally along the threaded cylinder 2451 during rotation. The threaded block 2452 drives the hinged support rod 2453 to move, causing the dosing pipe 244 to rotate around the central axis of the rotating pipe 243. This changes the angle between the dosing pipe 244 and the threaded cylinder 2451, thereby changing the dosing range. Furthermore, the dosing pipe 244 can also stir the wastewater and the drug solution during the dosing process, ensuring that the two are mixed evenly. The change in the angle of the dosing pipe 244 changes the stirring range, further improving the stirring effect.

[0079] As one embodiment of the present invention, please refer to Figures 1 to 4 , Figures 6 to 8 The pressurization assembly 25 includes:

[0080] A sliding air tube 251 passes through the bottom of the threaded cylinder 2451 and is slidably connected to it. A one-way valve 2 is provided inside the sliding air tube 251. An air hole is opened at the bottom of the sliding air tube 251 and the air hole is located inside the threaded cylinder 2451.

[0081] The bottom end of the connecting rod 252 is connected to the bottom end of the sliding air tube 251;

[0082] The abutting ring 253 is connected to the top of the connecting folding rod 252 and abuts against the threaded block 2452;

[0083] The elastic element 254 is sleeved on the sliding air tube 251, and one end is connected to the threaded cylinder 2451;

[0084] Piston ring 255 is connected to the top of sliding air tube 251 and abuts against the inner wall of threaded cylinder 2451; piston ring 255 is connected to the other end of elastic member 254.

[0085] The rotating ring frame 256 is rotatably connected to the threaded cylinder 2451 and communicates with its interior. The rotating ring frame 256 is connected to the rotating base 22.

[0086] The connecting hose 257 is connected at one end to the rotating ring frame 256 and communicates with its interior, and at the other end to the dosing tube 244 and communicates with its interior.

[0087] During the downward movement of the threaded block 2452, it compresses the abutment ring 253, causing the abutment ring 253 to move downward. This movement, via the connecting lever 252, drives the sliding air tube 251 downward, which in turn drives the piston ring 255 downward. This forces the gas inside the threaded cylinder 2451 into the dosing tube 244 through the connecting hose 257, increasing the pressure during drug dosing and ensuring the drug is successfully added to the treatment chamber 1. Under the pressure of the pressurized gas, the drug can be sprayed simultaneously from multiple outlets, forming multiple spray points, thus distributing the drug more evenly in the wastewater. During dosing, the pressurized gas continuously propels the drug forward, reducing the residence time of the drug in the pipe and lowering the risk of blockage. The elastic element 254 ensures that during the upward movement of the threaded block 2452, the sliding air tube 251 and piston ring 255 move upward synchronously, drawing outside air into the threaded cylinder 2451. The elastic element 254 can be a spring, a sheet spring, or similar material.

[0088] As one embodiment of the present invention, please refer to Figure 1 It also includes:

[0089] A stirring rod 6 is connected to a dosing tube 244, and the stirring rod 6 is provided in several groups;

[0090] The stirring rod 7 is connected to the rotating base 22, and the stirring rod 7 is provided in several groups.

[0091] Stirring rod 6 agitates the wastewater during the dosing process. Stirring rod 6 agitates the wastewater as the dosing pipe 244 moves. Stirring rod 7 agitates the liquid medicine as the rotating base 22 rotates, so that the liquid medicine is evenly added, thereby fully mixing the liquid medicine with the wastewater and improving the treatment effect.

[0092] The working principle of this invention is as follows: the liquid medicine is pre-stored in the material cylinder 21. When the liquid medicine needs to be added, the telescopic component 231 in the reciprocating assembly 23 starts to work, driving the sliding block 232 to slide along the processing chamber 1, and then driving the material cylinder 21 to reciprocate linearly along the processing chamber 1 through the fixed folding rod 233 and the fixed block 234.

[0093] During the movement of the material cylinder 21, the rotating component 241 in the dosing and stirring assembly 24 starts to work. The toothed plate 2412 drives the toothed ring 2411 to rotate, thereby driving the rotating base 22 to rotate. The rotation of the rotating base 22 causes the connected folding pipe 242 and dosing pipe 244 to rotate accordingly. The liquid medicine enters the rotating pipe 243 from the material cylinder 21 through the folding pipe 242, and then is added to the treatment chamber 1 from the outlet through the dosing pipe 244.

[0094] The pressurizing component 25 plays a role in this process. The sliding air tube 251 introduces external gas through the air hole. The gas is compressed by the piston ring 255 in the threaded cylinder 2451. The pressurized gas is delivered to the dosing tube 244 through the rotating ring frame 256 and the connecting hose 257, increasing the pressure when the liquid is added and ensuring that the liquid can be smoothly added into the treatment chamber 1.

[0095] Meanwhile, stirring rod 6 stirs the wastewater during the dosing process. Stirring rod 6 stirs the wastewater as the dosing pipe 244 moves, and stirring rod 7 stirs the liquid medicine as the rotating base 22 rotates, so that the liquid medicine is evenly added, thereby making the liquid medicine and wastewater fully mixed and improving the treatment effect.

[0096] After the wastewater is treated with chemicals in the treatment chamber 1, valve one in the filter chamber 3 is opened, and the wastewater enters the filter cone 4 through the filter chamber 3. The filter cone 4 plays a certain role in filtration and prevents large particles of impurities from clogging the outlet of the filter chamber 3. The filtered wastewater is discharged through the outlet 5. Valve two in the outlet 5 is used to control the discharge of wastewater.

[0097] 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. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
