Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology and relates to a fluoride-containing wastewater treatment device. Background Technology

[0002] The photovoltaic and semiconductor industries have developed rapidly in recent years and are sunrise industries. However, they are also high-energy-consuming, high-polluting, and water-intensive industries. Taking a 100MW polysilicon production line as an example, the daily water consumption is about 1,500 tons. Fluorine-containing wastewater accounts for about 70% of the total wastewater. Fluorine-containing wastewater is generated in the etching process. Fluorine-containing wastewater cannot be treated directly and needs to be defluorinated by a defluorination device.

[0003] Application No. 202321265167.1 discloses a defluorination device for treating fluoride-containing wastewater, belonging to the field of fluoride-containing wastewater treatment technology. The device includes a tank with a top cover fixedly connected to the top. A bidirectional drive assembly is fixedly connected to the middle of the top of the top cover. The bidirectional drive assembly includes a drive component, a clockwise stirring component, and a counterclockwise stirring component. The drive component rotates with the clockwise and counterclockwise stirring components, achieving bidirectional stirring and ensuring sufficient contact. An inlet pipe for adding wastewater is fixedly connected to the top of the top cover. A pH adjustment component is also connected to the top of the top cover. A quantitative feeding component for quantitatively adding calcium chloride is also connected to the top cover. Through the above methods, this invention facilitates rapid mixing, ensures sufficient contact between the fluoride-containing wastewater and the alkaline solution or calcium chloride, facilitates rapid pH adjustment or flocculation treatment, and simultaneously achieves quantitative calcium chloride addition.

[0004] The aforementioned device does not have a calcium chloride treatment unit. Some of the added calcium chloride is not fully crushed, resulting in large lumps. When such raw materials are added to wastewater, they not only dissolve slowly and cannot be quickly mixed with the liquid, but they are also very easy to clog the pipes during the addition process. Summary of the Invention

[0005] The purpose of this invention is to provide a fluoride-containing wastewater treatment device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A fluoride-containing wastewater treatment device includes a tank, an inlet pipe, a treatment tank, an inlet seat, and a suction pump body. The top of the tank is provided with a top cover, and the treatment tank is located on the top side of the top cover. A crushing and tamping head is provided inside the treatment tank. The top of the top cover is provided with an inlet pipe, and the top of the inlet pipe is provided with an inlet seat. The top of the inlet seat is provided with a filter seat, and a guide pipe is provided on the side of the filter seat. The bottom end of the guide pipe is connected to the interior of the treatment tank.

[0008] In the aforementioned fluoride-containing wastewater treatment equipment, the top of the treatment tank is provided with a tank cover, and the top of the crushing head is connected to a tamping rod, the top of which passes through the tank cover and rests on top of the tank cover.

[0009] In the aforementioned fluoride-containing wastewater treatment equipment, a suction pump body is provided on the side of the treatment tank, and the input end of the suction pump body is connected to the discharge port on the bottom side of the treatment tank.

[0010] In the aforementioned fluoride-containing wastewater treatment equipment, the output end of the suction pump body is connected to a suction hose, and one end of the suction hose is connected to the interior of the feed pipe.

[0011] In the above-mentioned fluoride-containing wastewater treatment equipment, a filter screen is provided inside the filter seat, and a pusher seat is provided on the top of the filter screen. A pusher rod is fixedly connected to one end of the pusher seat, and one end of the pusher rod passes through the filter seat and is placed on the top side of the filter seat.

[0012] Compared with the prior art, the advantages of the fluoride-containing wastewater treatment equipment of this utility model are as follows:

[0013] This application features a processing tank located at the top of the tank's cover, containing a tamping rod and a crushing head. Simultaneously, a feeding seat and a filter seat are located at the top of the feed pipe. During feeding, the material is placed into the filter seat and filtered through the filter screen. Qualified particles pass through the filter screen and enter the tank, while unqualified particles remain at the top of the filter screen. Then, a pusher rod is pushed, which in turn pushes the pusher seat, causing it to push the material on the filter screen into the guide pipe. The material flows into the processing tank along the guide pipe, where it is crushed into powder. Once the material is powdered, a suction pump can be activated to re-introduce the processed material into the feed pipe, thus achieving feeding. Attached Figure Description

Specifically, a filter screen 14 is provided inside the filter seat 8, and a pusher seat 15 is provided on the top of the filter screen 14. One end of the pusher seat 15 is fixedly connected to a pusher rod 16, and one end of the pusher rod 16 passes through the filter seat 8 and is placed on the top side of the filter seat 8.

[0024] This utility model discloses a fluoride-containing wastewater treatment device. A metal treatment tank 4 is installed at the top of the top cover 2 of the tank body 1. The treatment tank 4 contains a tamping rod 11 and a crushing head 12. Simultaneously, a feed seat 7 and a filter seat 8 are installed at the top of the feed pipe 3. During feeding, the material is placed into the filter seat 8 and filtered through the filter screen 14 inside the filter seat 8. Particles that meet the requirements pass through the filter screen 14 and enter the tank body 1, while large, non-compliant particles remain at the top of the filter screen 14. Then, the pusher rod 16 is pushed to push the material... The rod 16 pushes the pusher seat 15, which is made of rubber, so that the pusher seat 15 pushes the material on the filter screen 14 into the guide pipe 6.
