Currently, the main methods for treating chlorine-containing wastewater at home and abroad are lime neutralization precipitation and coagulation precipitation.

[0003] Chinese patent publication number CN211393977U discloses a fluorine-containing wastewater deep treatment device capable of recovering calcium fluoride, comprising a central radial flow sedimentation tank and a flocculation sedimentation tank, wherein the central radial flow sedimentation tank is provided with a fluorine-containing wastewater inlet pipe and a calcium-containing precipitant inlet pipe, and a first mud discharge pipe is provided at the bottom, wherein a first pneumatic cleaning device is provided in the first mud discharge pipe; an inclined tube filler and a water outlet weir are provided at the top of the central radial flow sedimentation tank, and a ring-shaped second pneumatic cleaning device is provided at the lower part of the inclined tube filler, The outlet weir is connected to the flocculation sedimentation tank, and a qualified discharge port is provided on the flocculation sedimentation area. The calcium fluoride precipitated by the device in the presence of fluidized calcium fluoride seeds is in the form of sand, has low water content and high purity, and can be recycled as a fluorine resource.

[0015] The present invention also discloses a method for deep treatment of fluorine-containing wastewater using the above-mentioned calcium fluoride recyclable device, the specific steps of which are as follows:

[0016] S1. In the process of deep treatment of fluorine-containing wastewater, the fluorine-containing wastewater and related reagents are introduced into the inner cavity of the shell from the feed pipe. The fluorine-containing wastewater and related reagents entering the inner cavity of the shell will first pass through the inclined tube filler, and the fluorine-containing wastewater and related reagents will be preliminarily mixed through the inclined tube filler. The fluorine-containing wastewater and related reagents flowing through the inclined tube filler enter the space where the mixing device is located under the guidance of the lower hopper;

[0017] S2. When the fluorine-containing wastewater and related agents enter the space where the mixing device is located, the transmission handle will drive the mixing roller to rotate, so that the mixing roller can drive the fluorine-containing wastewater and related agents that have entered the middle of the inner cavity of the shell to move, thereby promoting the reaction of the fluorine-containing wastewater and related agents. At the same time, when the mixing roller drives the fluorine-containing wastewater and related agents to move, the fluorine-containing wastewater and related agents will move outward. At this time, the fluorine-containing wastewater and related agents will contact the surfaces of multiple guide plates, and the fluorine-containing wastewater and related agents will be guided to the side close to the transmission handle through the multiple guide plates, further promoting the mixing of the fluorine-containing wastewater and related agents;

[0018] S3. The fluorine-containing substances fully mixed and reacted by the mixing device will move downward, and the preliminarily treated water will be in the upper part of the inner cavity of the shell. When the fluorine-containing wastewater and related reagents are continuously introduced into the inner cavity of the shell, the preliminarily treated water located in the upper part of the inner cavity of the shell will pass through the blocking mechanism and enter the inner cavity of the water outlet tank. After that, the preliminarily treated water will be introduced into other equipment through the drain pipe for deep treatment.

[0019] S4. When the fluorine-containing wastewater and the fluorine-containing substances produced by the reaction of the related agents move downward, the fluorine-containing substances will gradually enter the space below the funnel. The fluorine-containing substances entering the lower part of the funnel are collected by multiple mud discharge parts, and under the action of the limiter, the fluorine-containing substances are introduced into the space below the limiter, and then the fluorine-containing substances are transported out of the inner cavity of the shell through the screw and the mud discharge pipe;

[0020] S5. After the deep treatment device has been used for a period of time, cleaning liquid can be introduced into the inner cavity of the shell through the water inlet pipe to backwash it.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, by providing a drainage device, during the process of treating fluorine-containing wastewater, the flow rate of fluorine-containing wastewater entering the inner cavity of the shell may increase or decrease. The staff can adjust the distance between the multiple blocking members through the blocking mechanism to adjust the flow rate of the initially treated water entering the inner cavity of the water outlet tank, thereby improving the stability of the device.

[0023] 2. In the present invention, a mud discharge device is provided. After the fluorine-containing substance moves downward to the bottom of the funnel, a plurality of mud discharge parts collect the fluorine-containing substance entering the lower part of the funnel, and under the action of the limiter, the fluorine-containing substance is transported through the screw and the mud discharge pipe to be guided out of the inner cavity of the shell. The mud discharge parts will also push the liquid entering the space below the funnel upward, so that it passes through the filter holes on the funnel and enters the space where the mixing device is located again for reaction. At the same time, it prevents the fluorine-containing substance from clogging the filter holes on the funnel and affecting its filtering effect. Therefore, when the transmission handle rotates, it will also drive the cleaning plate to rotate, so that the cleaning plate cleans the filter holes on the funnel, thereby improving the reliability of the device.

[0024] 3. In the present invention, the deep treatment device can continuously introduce fluorine-containing wastewater and treat it. It is not necessary to introduce a part of the fluorine-containing wastewater into the relevant treatment device after the treatment is completed, and then discharge the fluorine-containing substances and the preliminarily treated water before treating the next part of the fluorine-containing wastewater, which improves the treatment efficiency of the deep treatment device.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Embodiment 1, as Figure 1 — Figure 4As shown, this embodiment discloses a fluorine-containing wastewater deep treatment device capable of recovering calcium fluoride, comprising a shell 1, a feed pipe 11 is arranged on one side of the upper end of the shell 1, a drain pipe 12 is arranged in the middle of the outer surface of the shell 1, a mud discharge pipe 13 and a water inlet pipe 14 are arranged on both sides of the lower part of the outer surface of the shell 1, a motor 2 is arranged in the middle of the upper end of the shell 1, a transmission handle 21 is arranged at the output end of the motor 2, the lower end of the transmission handle 21 extends to the lower part of the inner cavity of the shell 1, an inclined tube filler 3 is arranged in the upper part of the inner cavity of the shell 1, a drainage device 4 is arranged on the upper side of the middle part of the inner cavity of the shell 1, and a mixing device 5 is arranged on the lower side of the middle part of the inner cavity of the shell 1.

[0040] Specifically, in the process of deep treatment of fluorine-containing wastewater, fluorine-containing wastewater and related chemicals are introduced into the inner cavity of shell 1 from feed pipe 11, and the fluorine-containing wastewater and related chemicals entering the inner cavity of shell 1 will first pass through inclined tube filler 3, and then enter the middle part of the inner cavity of shell 1, and the mixing device 5 is driven by motor 2 and transmission handle 21 to make the mixing device 5 fully mix the fluorine-containing wastewater and related chemicals, and then the reacted fluorine-containing substances will move downward under the action of their own gravity, and then be discharged to the outside of shell 1 through mud discharge pipe 13, and the preliminarily treated water is introduced into other equipment through drainage device 4 and drainage pipe 12 for deep treatment. After the device is used for a period of time, it can be backwashed through water inlet pipe 14.

[0041] Furthermore, the inclined tube filler is an existing technology, and its functions are: 1. Increase the sedimentation area and improve the sedimentation efficiency; 2. Promote uniform distribution of water flow and prevent short-flow; 3. Reduce hydraulic resistance and improve processing capacity; 4. Easy to clean and maintain; 5. Strong adaptability and can cope with different water quality conditions, etc. This is an existing technology and will not be described in detail in this manual.

[0042] In the process of deep treatment of fluorine-containing wastewater, it is necessary to stir the fluorine-containing wastewater and related reagents through a mixing device 5 so that the fluorine-containing wastewater and related reagents can be fully mixed and reacted. Figure 5 As shown, the mixing device 5 includes a mixing roller 51, which is fixedly mounted on the middle of the outer surface of the transmission handle 21, and a plurality of guide plates 52 are arranged on the outer side of the mixing roller 51, and the plurality of guide plates 52 are obliquely mounted on the inner cavity surface of the shell 1.

[0043] Specifically, when the motor 2 drives the transmission handle 21 to rotate, the transmission handle 21 will drive the mixing roller 51 to rotate, so that the mixing roller 51 can drive the fluorine-containing wastewater and related chemicals entering the middle of the inner cavity of the shell 1 to move, thereby promoting the reaction of the fluorine-containing wastewater and related chemicals. At the same time, when the mixing roller 51 drives the fluorine-containing wastewater and related chemicals to move, the fluorine-containing wastewater and related chemicals will move outward. At this time, the fluorine-containing wastewater and related chemicals will contact the surface of the multiple guide plates 52, and the fluorine-containing wastewater and related chemicals will be guided to the side close to the transmission handle 21 through the multiple guide plates 52, further promoting the mixing of the fluorine-containing wastewater and related chemicals.

[0044] In the process of deep treatment of fluorine-containing wastewater, substances reacting with relevant reagents will move downward, and the preliminarily treated water will be in the upper part of the inner cavity of the shell 1. When the fluorine-containing wastewater is continuously introduced into the inner cavity of the shell 1, the preliminarily treated water located in the upper part of the inner cavity of the shell 1 will flow into the inner cavity of the drain device 4, and then the preliminarily treated water will be introduced into other equipment, such as Figure 6 and Figure 7 As shown, the drainage device 4 includes a water outlet trough 41, which is fixedly installed on the upper outer surface of a plurality of guide plates 52, the inner cavity of the water outlet trough 41 is communicated with the inner cavity of the drainage pipe 12, a blocking mechanism 42 is arranged on the inner side of the inner cavity surface of the water outlet trough 41, a lower hopper 43 is arranged above the water outlet trough 41, the lower hopper 43 is fixedly installed on the inner cavity surface of the shell 1, the lower end of the lower hopper 43 extends to the lower side of the middle part of the inner cavity of the shell 1, a leveling mechanism 44 is arranged on the inner surface of the water outlet trough 41, and the inner surface of the leveling mechanism 44 is fixedly connected to the lower outer surface of the lower hopper 43.

[0045] Specifically, after the fluorine-containing wastewater and related chemicals pass through the inclined tube filler 3, the fluorine-containing wastewater and related chemicals will first enter the inner cavity of the lower hopper 43, and then be introduced into the position of the mixing device 5 through the lower hopper 43. After the fluorine-containing wastewater and related chemicals are fully reacted through the mixing device 5, the reacted fluorine-containing substances will move downward, and the preliminarily treated water will be in the upper part of the inner cavity of the shell 1. When the fluorine-containing wastewater and related chemicals are continuously introduced into the inner cavity of the shell 1, the preliminarily treated water located in the upper part of the inner cavity of the shell 1 will pass through the blocking mechanism 42 and enter the inner cavity of the water outlet trough 41. Thereafter, the preliminarily treated water will be introduced into other equipment through the drain pipe 12 for deep treatment.

[0046] Furthermore, before the initially treated water passes through the blocking mechanism 42 and enters the inner cavity of the water outlet tank 41, the initially treated water first passes through the leveling mechanism 44, which is composed of a plurality of beveled plates and two mounting rings, such as Figure 7As shown, since the transmission handle 21 will continuously drive the mixing roller 51 to rotate, the mixing roller 51 drives the fluorine-containing wastewater and related chemicals to rotate. During this process, the fluorine-containing wastewater, related chemicals and other liquids will fluctuate. The lower hopper 43 can reduce this fluctuation to a certain extent, so that the preliminary treated water entering the upper part of the inner cavity of the shell 1 can relatively smoothly pass through the blocking mechanism 42 and enter the inner cavity of the water outlet trough 41, avoiding the situation where the mixing roller 51 pushes the fluorine-containing wastewater and related chemicals to move. The fluctuation pushes the preliminary treated water into the inner cavity of the water outlet trough 41, which may cause a part of the fluorine-containing substance to be pushed into the inner cavity of the water outlet trough 41.

[0047] In order to adjust the flow rate of the initially treated water into the inner cavity of the drainage device 4, as Figure 8 As shown, the blocking mechanism 42 includes a connecting ring 421, which is rotatably mounted on the inner surface of the water outlet trough 41, and a plurality of blocking members 424 are arranged on the inner side of the connecting ring 421, and the plurality of blocking members 424 are connected end to end. A transmission member 422 is arranged on the side of the outer surface of the connecting ring 421 away from the drain pipe 12, and the inner surface of the arc-shaped rack in the transmission member 422 is fixedly connected to the side of the outer surface of the connecting ring 421 away from the drain pipe 12, and a transmission rod 423 is arranged on the inner wall of the gear in the transmission member 422, and one end of the transmission rod 423 away from the transmission member 422 extends to the outside of the shell 1, and a hand wheel is arranged on the end of the transmission rod 423 away from the transmission member 422.

[0048] Specifically, in the process of treating fluorine-containing wastewater, the flow rate of fluorine-containing wastewater entering the inner cavity of shell 1 may increase or decrease. At this time, the staff can turn the hand wheel to drive the transmission member 422 to operate through the transmission rod 423, so that the transmission member 422 drives the multiple blocking members 424 to move through the connecting ring 421. During the movement of the multiple blocking members 424, the gaps between the multiple blocking members 424 will become larger or smaller, thereby adjusting the flow rate of the initially treated water entering the inner cavity of the water outlet trough 41.

[0049] In order to control the flow rate of primary treated water, such as Fig. 9 As shown, the blocking member 424 includes an arc-shaped limit frame 4241, which is fixedly installed on the inner cavity surface of the water outlet trough 41, and an arc-shaped baffle 4242 is slidably installed on one side of the inner cavity of the arc-shaped limit frame 4241, and one end of the arc-shaped baffle 4242 extends to the outside of the arc-shaped limit frame 4241, and the arc-shaped baffle 4242 is slidably installed on the inner cavity surface of the water outlet trough 41, and the outer surface of the arc-shaped baffle 4242 is fixedly connected to the upper end of the connecting ring 421 through an L-shaped rod, and both sides of the upper part of the arc-shaped limit frame 4241 and the arc-shaped baffle 4242 are provided with bevel angles 4243.

[0050] Specifically, when the staff turns the handwheel to drive the connecting ring 421 to rotate, the connecting ring 421 drives the arc-shaped baffles 4242 in the multiple blocking members 424 to rotate through the L-shaped rod, so that the arc-shaped baffles 4242 gradually enter the inner cavity of the arc-shaped limit frame 4241, and then the distance between the arc-shaped baffle 4242 and the arc-shaped limit frame 4241 in the adjacent blocking member 424 becomes larger, thereby increasing the flow rate of the initially treated water entering the inner cavity of the water outlet trough 41.

[0051] Furthermore, when the flow rate of fluorine-containing wastewater from the outside into the inner cavity of the shell 1 is within a certain range, the arc baffle 4242 can be moved to a position between two adjacent arc limit frames 4241. At this time, a gap will appear at the two upper bevels 4243 of the arc baffle 4242 and the two arc limit frames 4241. At this time, the preliminarily treated water can flow into the inner cavity of the water outlet tank 41 from the gap.

[0052] Embodiment 2: This embodiment further improves the mud discharge device 6 on the basis of embodiment 1. After the fluorine-containing wastewater reacts with the relevant reagents, the reacted fluorine-containing substance will gradually move downward, gradually enter the lower part of the inner cavity of the shell 1, and then enter the space where the mud discharge device 6 is located. At this time, the mud discharge device 6 can push the fluorine-containing substance downward and push the fluorine-containing wastewater upward, so that it can enter the space where the mixing device 5 is located again, so that it can fully react. Figure 1 — Figure 4 As shown, a mud discharge device 6 is provided at the lower part of the inner cavity of the shell 1.

[0053] In order to push the fluorinated substances downward and the fluorinated wastewater upward, e.g. Fig.10 and Fig.11 As shown, the mud discharge device 6 includes a funnel 61, which is fixedly installed at the lower part of the inner cavity of the shell 1. The outer surface of the funnel 61 is provided with filter holes. The lower part of the funnel 61 is provided with a cleaning plate 65, which is fixedly installed on the outer surface of the transmission handle 21. The cleaning plate 65 is adapted for use with the filter holes on the outer surface of the funnel 61. A plurality of mud discharge members 62 are provided below the cleaning plate 65. The plurality of mud discharge members 62 are all fixedly installed on the outer surface of the transmission handle 21. A limiting member 63 is provided at the lower end of the mud discharge member 62. A screw 64 is provided below the limiting member 63. The screw 64 is rotatably installed on the bottom of the inner cavity of the shell 1. One end of the screw 64 is connected to the lower part of the outer surface of the transmission handle 21 through a bevel gear set.

[0054] Furthermore, one end of the screw rod 64 extends into the inner cavity of the mud discharge pipe 13 , and the screw rod 64 is rotatably mounted on the inner cavity surface of the mud discharge pipe 13 .

[0055] Specifically, the fluorine-containing substances produced by the reaction of fluorine-containing wastewater and related reagents will move downward into the space below the funnel 61. At this time, the transmission handle 21 will drive the multiple mud discharge parts 62 to rotate, so that the multiple mud discharge parts 62 collect the fluorine-containing substances entering the lower part of the funnel 61, and under the action of the limit member 63, the fluorine-containing substances are introduced into the space below the limit member 63, and then the fluorine-containing substances are transported out of the inner cavity of the shell 1 through the screw 64 and the mud discharge pipe 13.

[0056] Furthermore, in the process of the mud discharge piece 62 collecting fluorine-containing substances, the mud discharge piece 62 will also push the liquid entering the space below the funnel 61 upward, so that it passes through the filter holes on the funnel 61 and enters the space where the mixing device 5 is located again for reaction. In this process, the fluorine-containing substances cannot pass through the filter holes on the funnel 61. At the same time, in order to prevent the fluorine-containing substances from clogging the filter holes on the funnel 61 and affecting its filtering effect, the cleaning plate 65 will also be driven to rotate when the transmission handle 21 rotates, so that the cleaning plate 65 cleans the filter holes on the funnel 61.

[0057] In order to prevent more fluorine-containing wastewater from being discharged from the outside of the housing 1 through the mud discharge pipe 13, Fig.12 As shown, the limiting member 63 includes a support plate 631, which is fixedly mounted on the inner cavity surface of the shell 1, and a rotating plate 632 is rotatably mounted on the upper end of the support plate 631. The inner surface of the rotating plate 632 is fixedly connected to the outer surface of the transmission handle 21, and a mud guide hole 634 is penetrated on one side of the lower end of the support plate 631, and a plurality of mounting holes 633 are arranged on the upper end of the rotating plate 632, and the plurality of mounting holes 633 are adapted for use with the mud guide holes 634.

[0058] Further, such as Fig.12 As shown, the mud discharge member 62 includes a mud discharge frame 621, which is fixedly mounted on the outer surface of the transmission handle 21, and the lower portion of the outer surface of the mud discharge frame 621 is fixedly connected to the inner cavity surface of the mounting hole 633. A water inlet hole is provided on one side of the outer surface of the mud discharge frame 621, and a plurality of guide plates 622 are provided on the inner cavity surface of the water inlet hole. Filter holes are provided on the other side and the upper end of the outer surface of the mud discharge frame 621, and a push plate 623 is provided on the upper end of the mud discharge frame 621.

[0059] Specifically, in the process of the transmission handle 21 driving the mud discharge piece 62 to rotate, the fluorine-containing substances and corresponding liquids such as fluorine-containing wastewater that enter the space below the funnel 61 will enter the inner cavity of the mud discharge frame 621 from the water inlet hole on the mud discharge frame 621, but the fluorine-containing wastewater and other liquids that enter the inner cavity of the mud discharge frame 621 will pass through the filter holes on the mud discharge frame 621 and flow out of the mud discharge frame 621, while the fluorine-containing substances will be retained in the inner cavity of the mud discharge frame 621 and then accumulated at the lower part of the mud discharge frame 621.

[0060] Furthermore, when the mud discharge member 62 rotates along with the driving handle 21 , the push plate 623 on the upper portion of the mud discharge frame 621 will push the liquid below the funnel 61 to move upward, and then allow the relevant liquid to pass through the filter holes on the funnel 61 .

[0061] Furthermore, as the mud discharge member 62 rotates with the transmission handle 21, the rotating disk 632 also rotates with the transmission handle 21. When a mud discharge frame 621 rotates to the side close to the mud discharge pipe 13, the opening at the bottom of the mud discharge frame 621 is connected to the inner cavity of the mud guide hole 634. At this time, the fluorine-containing substance accumulated in the inner cavity of the mud discharge frame 621 will be discharged to the bottom of the support disk 631, and then discharged to the outside of the shell 1 through the screw 64 and the mud discharge pipe 13.

[0062] Furthermore, in the process of discharging fluorine-containing substances from the mud discharge frame 621, in order to avoid more fluorine-containing wastewater from entering the space below the support plate 631, the staff can change the size of the mud guide hole 634 according to actual conditions. In the process of discharging fluorine-containing substances from the mud discharge frame 621, a small amount of fluorine-containing wastewater will still enter the space below the support plate 631, and then be discharged to the outside of the shell 1 by the screw 64 and the mud discharge pipe 13. However, through the action of the guide plate 622 and the mud discharge frame 621, the fluorine-containing wastewater content in the space below the funnel 61 is relatively small. Therefore, the deep treatment device can continuously introduce fluorine-containing wastewater and treat it. There is no need to introduce a part of fluorine-containing wastewater into the relevant treatment device like other related equipment, and then discharge the fluorine-containing substances and the preliminarily treated water after the treatment is completed, and then treat the next part of fluorine-containing wastewater, thereby improving the treatment efficiency.

[0063] Embodiment 3, the present application also discloses a method for using a withstand voltage detection device for electric power equipment, the specific steps are as follows:

[0064] S1. During the deep treatment of fluorine-containing wastewater, the fluorine-containing wastewater and related reagents are introduced into the inner cavity of the shell 1 from the feed pipe 11. The fluorine-containing wastewater and related reagents entering the inner cavity of the shell 1 will first pass through the inclined tube filler 3, and the fluorine-containing wastewater and related reagents will be preliminarily mixed through the inclined tube filler 3. The fluorine-containing wastewater and related reagents flowing through the inclined tube filler 3 enter the space where the mixing device 5 is located under the guidance of the lower hopper 43;

[0065] S2. When the fluorine-containing wastewater and the related agents enter the space where the mixing device 5 is located, the transmission handle 21 will drive the mixing roller 51 to rotate, so that the mixing roller 51 can drive the fluorine-containing wastewater and the related agents that have entered the middle of the inner cavity of the shell 1 to move, thereby promoting the reaction of the fluorine-containing wastewater and the related agents. At the same time, when the mixing roller 51 drives the fluorine-containing wastewater and the related agents to move, the fluorine-containing wastewater and the related agents will move outward. At this time, the fluorine-containing wastewater and the related agents will contact the surfaces of the multiple guide plates 52, and the fluorine-containing wastewater and the related agents will be guided to the side close to the transmission handle 21 through the multiple guide plates 52, further promoting the mixing of the fluorine-containing wastewater and the related agents.

[0066] S3, the fluorine-containing substances fully mixed and reacted by the mixing device 5 will move downward, and the preliminarily treated water will be in the upper part of the inner cavity of the shell 1. When the fluorine-containing wastewater and related reagents are continuously introduced into the inner cavity of the shell 1, the preliminarily treated water located in the upper part of the inner cavity of the shell 1 will pass through the blocking mechanism 42 and enter the inner cavity of the water outlet tank 41. After that, the preliminarily treated water will be introduced into other equipment through the drain pipe 12 for deep treatment;

[0067] S4, when the fluorine-containing wastewater and the fluorine-containing substances produced by the reaction of the related agents move downward, the fluorine-containing substances will gradually enter the space below the funnel 61, and the fluorine-containing substances entering the lower part of the funnel 61 are collected by multiple mud discharge members 62, and under the action of the limiter 63, the fluorine-containing substances are introduced into the space below the limiter 63, and then the fluorine-containing substances are transported out of the inner cavity of the shell 1 through the screw 64 and the mud discharge pipe 13;

[0068] S5. After the deep treatment device has been used for a period of time, cleaning liquid can be introduced into the inner cavity of the shell 1 through the water inlet pipe 14 to perform backwashing.

[0069] It should be noted that the specific installation method, circuit arrangement and connection method, and control method of the motor 2 used in the above-mentioned embodiment 1 are all conventional designs in the prior art and will not be elaborated in detail in the present invention.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
