Description

Technical Field

[0001] This utility model relates to the field of photovoltaic wastewater treatment technology, specifically a photovoltaic wastewater pretreatment device. Background Technology

[0002] Wastewater generated during photovoltaic (PV) production is characterized by complex composition, high pollutant concentration, and numerous recalcitrant substances. Cutting fluid, texturing wastewater, and etching wastewater, in particular, contain large amounts of silicon powder, fluorides, organic solvents, and heavy metal ions. PV wastewater pretreatment devices are used to treat wastewater generated during PV production. This type of wastewater typically contains certain chemicals and pollutants, requiring pretreatment before discharge or further treatment. The purpose of pretreatment is to reduce the concentration of pollutants in the wastewater, improve its quality, and ensure it meets discharge standards. Current pretreatment devices primarily use chemical agents to promote the aggregation and sedimentation of harmful substances in the wastewater, followed by agitation. However, most pretreatment devices lack control components in their feeding structures, making it difficult to control the amount of chemical agents. Excessive agents can lead to a significant increase in sludge formation, increasing treatment costs and environmental pollution risks. Conversely, insufficient chemical agents are insufficient to remove harmful substances from the wastewater, thus reducing the flexibility of the pretreatment device. Utility Model Content

[0003] The purpose of this invention is to provide a pretreatment device for photovoltaic wastewater to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic wastewater pretreatment device, comprising a treatment cylinder, a fixed block fixedly connected to the outside of the treatment cylinder, a rotating disk above the fixed block, a feeding pipe connected above the rotating disk, a stirring assembly inside the treatment cylinder, a second motor inside the fixed block, a positioning rod fixedly connected inside the rotating disk, an adjustment structure below the rotating disk, the positioning rod rotatably connected inside the adjustment structure, four storage cylinders inside the rotating disk, the adjustment structure rotatably connected outside the storage cylinders, an auxiliary rod rotatably connected inside the storage cylinders, a valve disc connected outside the auxiliary rod, a driving structure outside the feeding pipe, the driving structure connected to the rotating disk, and the driving structure connected to the auxiliary rod. The adjustment structure includes a swashplate, a guide rod, a baffle, and a protrusion, a column fixedly connected to one side of the baffle, the guide rod rotatably connected to the outside of the storage cylinders, and a coil spring sleeved on the guide rod.

[0005] As a further preferred embodiment of this technical solution, a connecting frame is connected to the outside of the processing cylinder, the auxiliary rod is rotatably connected inside the rotating disk, and the output shaft of the second motor is connected to the positioning rod.

[0006] As a further preferred embodiment of this technical solution, the swashplate is fixedly connected above the fixed block, the positioning rod is rotatably connected inside the swashplate, and the column overlaps with the swashplate.

[0007] As a further preferred embodiment of this technical solution, the protrusion is rotatably connected to the outside of the guide rod, the guide rod is connected to the outside of the storage cylinder through a coil spring, and the baffle is located below the storage cylinder.

[0008] As a further preferred embodiment of this technical solution, the drive structure includes a support plate, a telescopic device, a second bevel gear, and a second coil spring. The second bevel gear is fixedly connected to one end of the auxiliary rod, the second coil spring is sleeved on the outside of the auxiliary rod, the support plate is fixedly connected to the outside of the feed pipe, and the telescopic device is fixedly connected above the support plate.

[0009] As a further preferred embodiment of this technical solution, one end of the telescopic device is connected to a motor, the output shaft of the motor is connected to a rotating shaft, the rotating shaft is slidably connected inside the support plate, and one end of the rotating shaft is connected to a bevel gear.

[0011] This utility model provides a front-end pretreatment device for photovoltaic wastewater, which has the following beneficial effects:

[0012] (1) This utility model is equipped with a rotating disk, a storage cylinder, an adjustment structure, a positioning rod, and a second motor. The second motor drives the rotating disk to rotate around the positioning rod. When the rotating disk rotates, the column on the surface of the baffle moves on the surface of the inclined disk. When the column moves to the concave surface of the inclined disk, the baffle rotates around the guide rod. When the protrusion drives the guide rod to rotate, it will cause the first coil spring to deform. The chemical agent in the storage cylinder will be fed into the treatment cylinder. When the column is separated from the concave surface of the inclined disk, the baffle will be reset by the action of the first coil spring. Through the cooperation between the inclined disk, the column and the first coil spring, the chemical agent in multiple storage cylinders can be fed into the treatment cylinder in sequence. The amount of chemical agent can be controlled to avoid the wastewater treatment being affected by too much or too little chemical agent, thus ensuring the flexibility of the pretreatment device.

[0013] (2) By setting up a drive structure, the present invention applies a thrust to the motor by means of a telescopic device. When the first bevel gear meshes with the second bevel gear, the motor will drive the first bevel gear to rotate, and the auxiliary rod will rotate with the rotating shaft. When the auxiliary rod flips, it will cause the second coil spring to deform. When a storage cylinder contacts the feeding pipe, the valve disc inside will flip accordingly, thereby adjusting the angle of the valve disc. When the storage cylinder is separated from the feeding pipe, the valve disc will seal the storage cylinder to prevent external dust from entering the storage cylinder and affecting the chemical reagents.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4As shown in this embodiment, a photovoltaic wastewater pretreatment device includes a treatment cylinder 1, a fixing block 2 fixedly connected to the outside of the treatment cylinder 1, a rotating disk 3 above the fixing block 2, a feeding pipe 4 connected above the rotating disk 3, a stirring assembly 5 inside the treatment cylinder 1, a motor 11 inside the fixing block 2, a positioning rod 10 fixedly connected inside the rotating disk 3, an adjustment structure 7 below the rotating disk 3, the positioning rod 10 rotatably connected inside the adjustment structure 7, four storage cylinders 9 inside the rotating disk 3, and the adjustment structure 7... The storage cylinder 9 is rotatably connected to the outside of the storage cylinder 9. An auxiliary rod 12 is rotatably connected inside the storage cylinder 9. A valve disc 13 is connected to the outside of the auxiliary rod 12. A drive structure 8 is provided outside the feed pipe 4. The drive structure 8 is connected to the rotating disk 3 and the auxiliary rod 12. The adjustment structure 7 includes a swashplate 701, a guide rod 704, a baffle 702 and a protrusion 705. A column 703 is fixedly connected to one side of the baffle 702. The guide rod 704 is rotatably connected to the outside of the storage cylinder 9. A coil spring 706 is sleeved on the guide rod 704.

[0021] like Figure 1 and Figure 3 As shown, a connecting frame 6 is connected to the outside of the processing cylinder 1, an auxiliary rod 12 is rotatably connected to the rotating disk 3, the output shaft of the second motor 11 is connected to the positioning rod 10, the slant plate 701 is fixedly connected above the fixed block 2, the positioning rod 10 is rotatably connected inside the slant plate 701, the column 703 overlaps with the slant plate 701, the protrusion 705 is rotatably connected to the outside of the guide rod 704, the guide rod 704 is connected to the outside of the storage cylinder 9 through the coil spring 706, and the baffle 702 is located below the storage cylinder 9;

[0022] By setting a coil spring 706, the motor 11 drives the rotating disk 3 to rotate around the positioning rod 10. When the rotating disk 3 rotates, the column 703 on the surface of the baffle 702 will move on the surface of the swashplate 701. When the column 703 moves to the concave surface of the swashplate 701, the baffle 702 will rotate around the guide rod 704. When the protrusion 705 drives the guide rod 704 to rotate, it will cause the coil spring 706 to deform, so that the coil spring 706 provides a certain support for the rotation of the baffle 702. When the baffle 702 loses resistance, it will be reset by the coil spring 706, thus preventing the leakage of the chemical agent inside the storage cylinder 9 during its rotation.

[0023] like Figure 4As shown, the drive structure 8 includes a support plate 801, a telescopic device 802, a second bevel gear 806, and a second coil spring 807. The second bevel gear 806 is fixedly connected to one end of the auxiliary rod 12, and the second coil spring 807 is sleeved on the outside of the auxiliary rod 12. The support plate 801 is fixedly connected to the outside of the feed pipe 4. The telescopic device 802 is fixedly connected above the support plate 801. One end of the telescopic device 802 is connected to a first motor 803. The output shaft of the first motor 803 is connected to a rotating shaft 804. The rotating shaft 804 is slidably connected inside the support plate 801. One end of the rotating shaft 804 is connected to a first bevel gear 805. The first bevel gear 805 meshes with the second bevel gear 806. The second coil spring 807 is sleeved on the outside of the auxiliary rod 12. The auxiliary rod 12 is connected to the rotating disk 3 through the second coil spring 807.

[0024] By setting up an expansion joint 802 and a motor 803, the expansion joint 802 applies a thrust to the motor 803. When the bevel gear 805 meshes with the bevel gear 806, the motor 803 will drive the bevel gear 805 to rotate. When the chemical agent is discharged, the expansion joint 802 drives the bevel gear 805 to disengage from the bevel gear 806, and the valve disc 13 will be reset by the action of the coil spring 807. This allows control of the rotation angle of the valve disc 13, which facilitates control of the chemical agent being discharged according to the actual situation and avoids excessive chemical agent being stored in the storage cylinder 9.

[0025] This utility model provides a front-end pretreatment device for photovoltaic wastewater, the specific working principle of which is as follows:

[0026] When the pretreatment device is treating the internal sewage, the external storage tank will transport the chemical agent through the feed pipe 4. During the transport process, the telescopic device 802 will apply a thrust to the motor 803. When the bevel gear 805 meshes with the bevel gear 806, the motor 803 will drive the bevel gear 805 to rotate. The auxiliary rod 12 will rotate with the rotating shaft 804. When the auxiliary rod 12 flips, it will cause the coil spring 807 to deform. When the valve disc 13 flips, the chemical agent in the feed pipe 4 will slide into the storage cylinder 9. When the chemical agent is discharged, the telescopic device 802 will drive the bevel gear 805 to disengage from the bevel gear 806, and the valve disc 13 will be reset by the action of the coil spring 807.

[0027] The rotating disk 3 is driven by motor 211 to rotate around the positioning rod 10. When the rotating disk 3 rotates, the column 703 on the surface of the baffle 702 will move on the surface of the swash plate 701. When the column 703 moves to the concave surface of the swash plate 701, the baffle 702 will rotate around the guide rod 704. When the protrusion 705 drives the guide rod 704 to rotate, it will cause the coil spring 1 706 to deform. The chemical agent in the storage cylinder 9 will be discharged into the processing cylinder 1. When the column 703 is separated from the concave surface of the swash plate 701, the baffle 702 will be reset by the action of the coil spring 1 706.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
