[0002] Pretreatment of toxic pharmaceutical wastewater is a crucial step in the pharmaceutical industry. Its purpose is to reduce the toxicity of wastewater through physical, chemical, or biological treatment methods, thereby mitigating its harm to the environment and human health. The pretreatment of toxic pharmaceutical wastewater often employs a combination of treatment technologies to ensure that wastewater discharge meets environmental standards.

[0003] Existing pretreatment devices for toxic pharmaceutical wastewater remove large suspended solids, such as solid waste and impurities, from wastewater through physical pretreatment methods using filters. However, prolonged use can easily lead to clogging of the filter inlet, thereby reducing filtration efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a pretreatment device for toxic pharmaceutical wastewater.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A pretreatment device for toxic pharmaceutical wastewater includes a treatment tank, a partition installed in the middle of the treatment tank, a filter screen fixed on the partition, a guide plate installed at one end of the partition, a rotating component at the bottom of the guide plate, and a cleaning component on one side of the rotating component.

[0007] The rotating assembly includes a support shaft and a water guide frame, wherein the support shaft is fixed inside the treatment tank and the water guide frame is rotatably connected to the support shaft;

[0008] The cleaning assembly includes a float located below the partition, a connecting plate fixed to the top of the float, connecting rods symmetrically installed above the top of the connecting plate, a cleaning plate fixed to the top of the connecting rods, and the connecting rods penetrating the partition. The connection points between the connecting rods and the partition have sealing structures.

[0009] Preferably, the guide plate is inclined upwards, and the outer side of the water guide frame is located outside the guide plate.

[0010] Preferably, a guide assembly is provided on the outer side of the connecting plate, the guide assembly including a groove and a slider.

[0011] Preferably, the slider is fixed to the outside of the connecting plate, and the slider is slidably connected to the groove.

[0012] Preferably, the processing chamber is divided into a processing chamber and a drainage chamber by the partition, wherein the filter screen is located in the processing chamber, the guide plate and the rotating assembly are located in the drainage chamber, and the cleaning assembly passes through the partition.

[0013] Preferably, a water inlet pipe is installed at the top of the treatment tank, and the water inlet pipe is connected to the treatment chamber.

[0014] Preferably, a drain pipe is installed at the bottom of the processing box, and the drain pipe is connected to the drain cavity.

[0015] The beneficial effects of this technology are:

[0016] By incorporating a guide plate, a rotating assembly, and a cleaning assembly, wastewater can move through the guide plate after being filtered by the filter screen. As the wastewater flows downwards through the guide plate, it impacts the water guide frame inside the rotating assembly. The water guide frame rotates along the support shaft, causing the water surface in the drainage chamber to sway. This swaying of the water surface causes the float in the cleaning assembly to sway, which in turn drives the cleaning plate to float up and down on one side of the filter screen via the connecting plate and connecting rod. This up-and-down movement of the cleaning plate cleans the area below the filter screen, preventing impurities from clogging the filter screen and improving filtration efficiency.

[0023] like Figures 1-3 As shown, this embodiment provides a pretreatment device for toxic pharmaceutical wastewater, including a treatment tank 1. A partition 2 is installed in the middle of the treatment tank 1, and a filter screen 3 is fixed on the partition 2. The filter screen 3 can filter the wastewater. A guide plate 4 is installed at one end of the partition 2. The guide plate 4 can guide the wastewater. A rotating component 5 is provided at the bottom of the guide plate 4, and a cleaning component 6 is provided on one side of the rotating component 5.

[0024] The rotating assembly 5 includes a support shaft 501 and a water guide frame 502. The support shaft 501 is fixed inside the treatment box 1, and the water guide frame 502 is rotatably connected to the support shaft 501, so that the water guide frame 502 can rotate along the support shaft 501 when impacted by water flow.

[0025] The cleaning assembly 6 includes a float 601 located below the partition 2. The buoyancy of the float 601 can drive the connecting plate 602 to move up and down. The connecting plate 602 is fixed to the top of the float 601. The connecting plate 602 can connect the connecting rod 603 and the float 601. The connecting rod 603 is symmetrically installed above the top of the connecting plate 602. The connecting rod 603 can connect the cleaning plate 604 and the connecting plate 602. The cleaning plate 604 is fixed to the top of the connecting rod 603. The cleaning plate 604 can clean one side of the filter screen 3. The connecting rod 603 passes through the partition 2. There is a sealing structure at the connection between the connecting rod 603 and the partition 2.

[0026] like Figure 2 As shown, the guide plate 4 is inclined upwards, and the outer side of the water guide frame 502 is located outside the guide plate 4, which can increase the impact force of the wastewater when it falls through the guide plate 4.

[0027] like Figures 2-3 As shown, a guide component 7 is provided on the outer side of the connecting plate 602. The guide component 7 includes a groove 701 and a slider 702, which facilitates the guiding of the connecting plate 602 through the guide component 7.

[0028] like Figures 2-3 As shown, the slider 702 is fixed on the outside of the connecting plate 602, and the slider 702 is slidably connected to the slide groove 701, which allows the connecting plate 602 to move up and down along the slide groove 701 via the slider 702.

[0029] like Figures 2-3 As shown, the treatment chamber 1 is divided into a treatment chamber 8 and a drainage chamber 9 by a partition 2. The filter screen 3 is located in the treatment chamber 8, the guide plate 4 and the rotating assembly 5 are located in the drainage chamber 9, and the cleaning assembly 6 penetrates through the partition 2 to facilitate the filtration of wastewater in the treatment chamber 8 of the treatment chamber 1, thereby filtering out toxic particulate matter. The filtered wastewater then enters the drainage chamber 9.

[0030] like Figures 1-2As shown, a water inlet pipe 10 is installed at the top of the treatment tank 1. The water inlet pipe 10 is connected to the treatment chamber 8, so that wastewater can enter the treatment chamber 8 of the treatment tank 1 through the water inlet pipe 10.

[0031] like Figures 1-2 As shown, a drain pipe 11 is installed at the bottom of the treatment tank 1. The drain pipe 11 is connected to the drain chamber 9, so that the treated wastewater can be discharged through the drain pipe 11.

[0032] Working principle of this device: In actual use, wastewater enters the treatment chamber 8 of the treatment tank 1 through the inlet pipe 10. During the flow, the wastewater is filtered through the filter screen 3 to remove toxic particles. The filtered wastewater then enters the drain chamber 9. During the flow, the wastewater moves through the guide plate 4, which increases the impact force of the wastewater as it falls. As the wastewater flows downward through the guide plate 4, it impacts the water guide frame 502 in the rotating component 5. The water guide frame 502 rotates along the support shaft 501, causing the water surface in the drain chamber 9 to sway. The swaying of the water surface causes the float 601 in the cleaning component 6 to sway, which in turn drives the cleaning plate 604 to float up and down on one side of the filter screen 3 through the connecting plate 602 and the connecting rod 603. The up and down movement of the cleaning plate 604 cleans the area below the filter screen 3, preventing impurities from clogging the filter screen 3 and improving the filtration efficiency. The wastewater is then discharged through the drain pipe 11 at the bottom of the drain chamber 9 for further treatment.

[0033] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
