Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a high-efficiency mixing reactor for silicon removal agents in photovoltaic wastewater. Background Technology

[0002] In the photovoltaic industry, especially in the processes of silicon wafer cutting, cleaning, and etching, a large amount of silicon-containing wastewater is generated. Soluble silicon in the wastewater (mainly in the form of silicate or colloidal silicon) is difficult to remove and is prone to scaling, clogging of membrane systems, or affecting subsequent discharge compliance in subsequent treatment units. Traditional silicon removal methods mainly rely on chemical precipitation, flocculation, or adsorption technologies, but these have problems such as low reagent utilization, long reaction time, and poor sedimentation effect. Improving silicon removal efficiency and reducing reagent consumption and sludge generation has important engineering application value for photovoltaic wastewater treatment.

[0003] The applicant discovered through a search that a Chinese patent discloses "A High-Efficiency Mixing Device for Pharmaceutical Agents," with publication (announcement) number "CN214810453U." This patent mainly uses a motor that rotates counterclockwise to drive a reciprocating screw, causing the pressure plate to move up and down. The flow of gas inside the device is ensured through a feed pipe. Then, the rotation of the reciprocating screw drives the stirring plate to rotate and mix the pharmaceutical agent in the circular tube. The stirring plate also scrapes the inner wall of the circular tube. However, in this device, the reactor is a single unit, and sediment accumulates at the bottom of the disc. Workers may need tools to reach the sediment inside, making the cleaning process time-consuming and labor-intensive, and it is difficult to guarantee the cleaning effect. It is also not easy to clean the stirring plate. Therefore, we propose a high-efficiency mixing reactor for silicon removal agents in photovoltaic wastewater. Utility Model Content

The limiting block is provided with a limiting groove, the side wall of the limiting groove has a certain elasticity, and the limiting groove and the bolt cooperate with each other.

[0009] As a preferred embodiment, the mixing structure includes a rotating shaft, a stirring rod, a motor, a support plate, a water pump, a connecting pipe, a buckle, a liquid outlet pipe, and a filter screen.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set installation structure, the connecting shell and sealing ring are inserted into the slot, then the bolts are snapped into the limit block, and finally the nuts are screwed in to fix it, so that the outer shell and the bottom shell become a whole. When it is necessary to clean the internal sediment or repair the mixed structure and other parts, the staff can quickly remove the bottom shell from the outer shell, reduce equipment downtime, improve work efficiency, and ensure that the outer shell and the bottom shell will not easily separate or loosen when subjected to these external forces. The sealing ring forms a sealing barrier between the connecting shell and the slot, effectively preventing liquid from seeping out from the connection.

[0013] 2. In the set mixing structure, the wastewater and aluminum salt are stirred by the stirring rod to make them fully mixed. After the mixture is evenly mixed, it is allowed to stand for a period of time to allow the sediment to settle completely.

After the supernatant is pumped out, it can be transported to other treatment equipment or storage containers for centralized processing in the next step. This effectively realizes the connection of the wastewater treatment process and improves the working efficiency of the entire wastewater treatment system. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see the appendix Figure 1 - Appendix Figure 5 A high-efficiency mixing reactor for silicon removal agents in photovoltaic wastewater includes a reaction structure 1, an installation structure 2, a mixing structure 3, and a drain valve 4. The installation structure 2 is installed at the bottom of the reaction structure 1, the mixing structure 3 is disposed inside the reaction structure 1, and the drain valve 4 is installed at the bottom of the installation structure 2. The reaction structure 1 includes a shell 11, a support frame 12, a water inlet pipe 13, a top cover 14, and a feeding hopper 15. The support frame 12 is fixedly installed on the side wall of the shell 11 to provide support for the shell 11. The water inlet pipe 13 is installed at the top of the side wall of the shell 11, the top cover 14 is installed at the top of the shell 11, and the feeding hopper 15 is fixedly installed on the top cover 14.

[0026] Mounting structure 2 includes a bottom shell 21, a connecting shell 22, a sealing ring 23, a slot 24, a fixing block 25, a connecting shaft 26, bolts 27, nuts 28, and a limiting block 29. The connecting shell 22 is fixedly installed on the top of the bottom shell 21. The sealing ring 23 is fixedly attached to the inner wall of the connecting shell 22. The slot 24 is located on the inner wall of the outer shell 11. The slot 24 cooperates with the connecting shell 22 and the sealing ring 23. By inserting the connecting shell 22 and the sealing ring 23 into the slot 24, the bottom shell 21 and the outer shell 11 are combined to form a complete reactor. The fixing block 25 is fixedly installed on the side wall of the outer shell 11. The connecting shaft 26... The components are fixedly installed between the fixing blocks 25. Bolt 27 is fitted onto the connecting shaft 26, and bolt 27 and connecting shaft 26 are rotatably connected. Nut 28 is threaded onto bolt 27. Limiting block 29 is fixedly installed on the side wall of bottom shell 21. Limiting block 29 is provided with a limiting groove. The side wall of the limiting groove has a certain elasticity. The limiting groove and bolt 27 cooperate with each other to insert bolt 27 into the limiting groove of limiting block 29. Then, the nut 28 is turned to fix bolt 27, thereby realizing the fixed connection between outer shell 11 and bottom shell 21. By setting sealing ring 23, the risk of wastewater leakage is reduced. Drain valve 4 is installed at the bottom of bottom shell 21.

[0027] Specifically, in the installation structure 2, the connecting shell 22 and the sealing ring 23 are inserted into the slot 24, then the bolt 27 is snapped into the limiting block 29, and finally the nut 28 is screwed in to fix it, so that the outer shell 11 and the bottom shell 21 become a whole. When it is necessary to clean the internal sediment or repair the mixing structure 3 and other components, the staff can quickly remove the bottom shell 21 from the outer shell 11, reducing equipment downtime and improving work efficiency. It can ensure that the outer shell 11 and the bottom shell 21 will not easily separate or loosen when subjected to these external forces. The sealing ring 23 forms a sealing barrier between the connecting shell 22 and the slot 24, effectively preventing liquid from seeping out from the connection.

[0028] Example 2:

[0029] Please see the appendix Figure 6 - Appendix Figure 8 The mixing structure 3 includes a rotating shaft 31, a stirring rod 32, a motor 33, a support plate 34, a water pump 35, a connecting pipe 36, a buckle 37, a liquid outlet pipe 38, and a filter screen 39. The rotating shaft 31 is rotatably mounted on the top cover 14, and the stirring rod 32 is fixedly mounted on the rotating shaft 31. The motor 33 is fixedly mounted on the top of the top cover 14, and the motor shaft of the motor 33 is fixedly connected to the top of the rotating shaft 31. The motor 33 drives the rotating shaft 31 to rotate, thereby driving the stirring rod 32 to stir. The support plate 34 is fixedly mounted on the outer shell 11. On the side wall, the water pump 35 is fixedly installed on the top of the support plate 34. The connecting pipe 36 is connected to the liquid inlet end of the water pump 35, and the free end of the connecting pipe 36 extends into the inside of the outer shell 11. The buckle 37 is fixedly installed on the inner wall of the outer shell 11 and limits the connecting pipe 36. The liquid outlet pipe 38 is installed at the liquid outlet end of the water pump 35. The water pump 35 can extract the supernatant after reaction in the outer shell 11 and the bottom shell 21. The filter screen plate 39 is fixedly installed inside the drain valve 4 and can filter the wastewater.

[0030] Specifically, in the mixing structure 3, the wastewater and aluminum salt are stirred by the stirring rod 32 to ensure thorough and uniform mixing. After uniform mixing, the mixture is allowed to stand for a period of time to allow the sediment to settle completely. At this time, the water pump 35 is started to extract the supernatant from the outer shell 11 and the bottom shell 21. After the supernatant is extracted by the water pump 35, it can be transported to other treatment equipment or storage containers for centralized processing in the next step. This effectively realizes the connection of the wastewater treatment process and improves the working efficiency of the entire wastewater treatment system.

[0031] Working principle of this utility model: This utility model is a high-efficiency mixing reactor for silicon removal agents in photovoltaic wastewater. Wastewater containing soluble silicon (SiO2 or silicate ions) is added to the outer shell 11 through the inlet pipe 13. Aluminum salts (such as polyaluminum chloride PAC, aluminum sulfate, etc.) are added to the feeding hopper 15. The motor 33 is started, and the motor shaft drives the rotating shaft 31 to rotate, thereby driving the stirring rod 32 to rotate. The stirring rod 32 agitates the wastewater and aluminum salts, making them fully mixed. After the mixture is evenly mixed, it is allowed to stand for a period of time to allow the sediment to completely settle. At this time, the water pump 35 is started to pump out the supernatant in the outer shell 11 and the bottom shell 21. The remaining waste liquid is discharged by opening the drain valve 4. During discharge, the waste liquid is filtered through the filter screen 39. After the waste liquid is discharged, the nut 28 is loosened, causing the bolt 27 to fall out of the limiting block 29. Then, the bottom shell 21 is detached from the slot 24 in the outer shell 11, separating the bottom shell 21 from the outer shell 11. Most of the sediment accumulates inside the bottom shell 21. By removing the bottom shell 21 from the outer shell 11, it is convenient to clean the sediment, as well as the inner wall of the outer shell 11, the rotating shaft 31, and the stirring rod 32. After cleaning, the connecting shell 22 and the sealing ring 23 are inserted into the slot 24, and then the bolt 27 is inserted into the limiting block 29. Finally, the nut 28 is tightened to fix it, making the outer shell 11 and the bottom shell 21 a whole.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
