Description
Technical Field
[0001] The utility model relates to the technical field of wastewater treatment, and in particular, to an integrated defluorination and precipitation wastewater treatment device. Background Art
[0002] Defluorination and precipitation is an operation to remove fluoride ions from water. By adding certain chemical substances to the fluoride-containing water, a chemical reaction occurs with the fluoride ions to form a fluoride precipitate that is insoluble in water, thereby separating the fluoride from the water. However, in actual operation, due to the inability to accurately control the addition amount of reactants, the addition amount of reactants will increase, and finally wastewater will be formed.
[0003] The defluorination and precipitation operation generally adds reactants to the inside of the sedimentation tank to react with water. By standing, liquid separation is formed. The upper part is the clear liquid and the lower part is the turbid liquid. After the clear liquid is discharged, the wastewater at the bottom needs to be cleaned. The common current cleaning method is for workers to use cleaning tools to clean the wastewater inside the sedimentation tank and also clean the waste residue at the inner bottom, which wastes time and reduces work efficiency.

[0028] Embodiment
[0029] Refer to Figures 1-4, the utility model provides a technical solution: an integrated defluorination and precipitation wastewater treatment device, including a treatment tank 1 and a wastewater treatment mechanism 4. A slag discharge bin 2 and a drain pipe 3 are respectively installed at the bottom of the treatment tank 1. The wastewater treatment mechanism 4 includes a multi-stage cylinder 41, which is installed above the treatment tank 1. A connecting plate 411 is fixedly installed at the telescopic end of the multi-stage cylinder 41. One end of a pushing plate 42 is rotatably connected to the connecting plate 411, and the bottom end of the pushing plate 42 is arranged inside the treatment tank 1 for draining wastewater. A centrifuge 43 is installed at the bottom of the treatment tank 1, and the feeding hole of the centrifuge 43 is fixedly connected to the slag discharge bin 2 for discharging wastewater into the centrifuge 43.
[0030] In a preferred embodiment, a positioning frame 5 is fixedly installed on the upper surface of the treatment tank 1, and the multi-stage cylinder 41 is fixedly installed on the top of the positioning frame 5. To ensure the stable use of the multi-stage cylinder 41 in this device, a positioning frame 5 is fixedly installed on the upper surface of the treatment tank 1, and the multi-stage cylinder 41 is fixedly installed on the positioning frame 5. By controlling the stable use of the multi-stage cylinder 41 in this way, the rotation of the pushing plate 42 can be stably controlled, which is convenient for pushing out the waste liquid.
[0031] In a preferred embodiment, a positioning plate 6 is fixedly installed on the inner wall of the treatment tank 1, a water baffle 7 is slidably connected to the inner side of the positioning plate 6, a frame body 8 is stably installed above the positioning plate 6, a spring 9 is installed at the inner top of the frame body 8, and a movable plate 10 is fixedly installed at one end of the spring 9. The movable plate 10 corresponds to the position of the water baffle 7. In this device, the water baffle 7 is slidably installed inside the frame body 8, and a movable plate 10 that can move up and down is arranged inside the frame body 8 and is connected by a spring 9, so as to control the water baffle 7 to automatically return to the initial position after being lifted, which is convenient for use.
[0032] In a preferred embodiment, liquid discharge holes 11 are respectively opened at the left and right ends of the inner bottom of the treatment tank 1. One of the liquid discharge holes 11 is communicated with the inside of the slag discharge bin 2, and the other liquid discharge hole 11 is communicated with the inside of the drain pipe 3. The liquid inside the treatment tank 1 will be separated after treatment and standing. The upper layer is clear liquid and the lower layer is wastewater. Therefore, two liquid discharge holes 11 are provided to collect the clear liquid and the waste liquid respectively.
[0033] While handling the liquid, in order to prevent the liquid from flowing out randomly, a liquid separation mechanism 12 is installed inside the treatment tank 1. The liquid separation mechanism 12 includes a hollow chamber 121. Round holes 13 are respectively formed on the outer surface of the hollow chamber 121 for water inlet and drainage. And the heights of the round holes 13 on both side surfaces of the hollow chamber 121 are set differently. The liquid separation mechanism 12 further includes a blocking plate 122. The blocking plate 122 is fixedly installed on the telescopic end of the multi-stage cylinder 41, and the blocking plate 122 is slidably installed inside the hollow chamber 121. A rubber pad 14 is fixedly installed on the outer surface of the blocking plate 122. The outer side surface of the rubber pad 14 is slidably connected to the inner wall of the hollow chamber 121 for water blocking. A support rod 15 is fixedly installed at the bottom position of the treatment tank 1, and a support frame 16 is fixedly installed at the position inside the support rod 15. The centrifuge 43 is fixedly installed on the support frame 16.
[0034] During actual use, in actual operation, the blocking plate 122 will be installed inside the hollow chamber 121. And under the action of the rubber pad 14, it can prevent the water treated inside the treatment tank 1 from directly flowing out from the inside of the round hole 13. By closing the round hole 13, the water can be concentrated for treatment. After the treatment is completed and the water is left standing, the telescopic end of the multi-stage cylinder 41 retracts and drives the blocking plate 122 to be pulled out from the inside of the hollow chamber 121, and the round hole 13 is opened to dredge the round hole 13. After the round hole 13 is dredged, the supernatant will first flow into the inside of the hollow chamber 121 through the round hole 13, and then flow out from the round hole 13 on the other side surface of the hollow chamber 121, so as to transport the supernatant to the position of the drain pipe 3, and the clear liquid will be discharged from the position of the drain pipe 3, and then it can be collected.
[0035] Specifically, the working process or working principle of an integrated defluorination and precipitation wastewater treatment device is as follows: For the defluorination and precipitation operation, generally, reactants are added into the sedimentation tank and react with water. Through standing, liquid separation is formed. The upper part is the clear liquid and the lower part is the turbid liquid. After the clear liquid is discharged, it is necessary to clean the wastewater at the bottom. The common cleaning method at present is that the staff uses cleaning tools to clean the wastewater inside the sedimentation tank and also clean the waste residue at the inner bottom, which wastes time and reduces work efficiency. Therefore, this device is designed to solve this problem.
[0036] Through this device, the waste residue and wastewater can be automatically cleaned into the centrifuge 43. The centrifuge 43 performs centrifugation on the wastewater to separate the solid and liquid in the waste liquid, which is convenient for treating the waste liquid and realizing solid-liquid separation. The specific operation is as follows: Connect to an external power supply. By adding certain chemical substances to the fluorine-containing water, a chemical reaction occurs with the fluoride ions to generate fluoride precipitates that are insoluble in water. Common precipitants include calcium salts such as lime and calcium chloride, and aluminum salts such as aluminum sulfate and polyaluminum chloride, etc. Taking calcium salts as an example, calcium ions combine with fluoride ions to form calcium fluoride precipitate. The reaction formula is: Ca 2+ +2F -→CaF2↓。
[0037] After adding the precipitant and allowing it to stand for a period of time, the liquid will separate. The upper layer is the supernatant and the lower layer is the waste liquid. In actual operation, the blocking plate 122 will be installed inside the hollow bin 121. Under the action of the rubber pad 14, it can prevent the water treated inside the treatment tank 1 from directly flowing out through the round hole 13. By closing the round hole 13, the water can be concentrated for treatment. After the treatment is completed and the liquid has settled, the telescopic end of the multi-stage cylinder 41 retracts and drives the blocking plate 122 to be pulled out from inside the hollow bin 121, and the round hole 13 is opened to dredge the round hole 13.
[0038] After the round hole 13 is dredged, the supernatant will first flow into the inside of the hollow bin 121 through the round hole 13, and then flow out from the round hole 13 on the other side surface of the hollow bin 121, so as to convey the supernatant to the position of the drain pipe 3, and the clear liquid will be discharged from the position of the drain pipe 3, and then it can be collected.
[0039] When the liquid level in the treatment tank 1 is lower than the position of the round hole 13, the telescopic end of the multi-stage cylinder 41 is used to push the blocking plate 122 to move into the inside of the hollow bin 121. At this time, the position where the multi-stage cylinder 41 pushes the blocking plate 122 to move should be greater than the initial position of the blocking plate 122. When the telescopic end of the multi-stage cylinder 41 extends, it will not only push the blocking plate 122 to move, but also drive the connecting plate 411 to move until the pushing plate 42 is moved to the position of the inner bottom of the treatment tank 1. When the bottom of the pushing plate 42 touches the inner bottom of the treatment tank 1, continue to control the multi-stage cylinder 41 to work. As the telescopic end of the multi-stage cylinder 41 continuously extends, it will control the pushing plate 42 to rotate inside the treatment tank 1, and control the pushing plate 42 to move towards the position of the water baffle 7, and control one end of the pushing plate 42 to move to the bottom position of the water baffle 7, and then continue to control the pushing plate 42 to move. Since the outer surface of the pushing plate 42 is provided with arc-shaped blocks, it can push the water baffle 7 upward to enable the water to flow normally.
[0040] While the pushing plate 42 is moving, it will push the waste residue and waste water towards the position of the water baffle 7. When the water baffle 7 is controlled to move upward, there is a gap between the water baffle 7 and the inner bottom of the treatment tank 1. At this time, the waste residue and waste water can flow into the inside of the slag discharge bin 2 from this position, and the waste residue and waste water will then enter the inside of the centrifuge 43. Through the operation of the centrifuge 43, the solids in the liquid are separated to facilitate the treatment of the waste water.
[0041] According to the actual usage situation, when there is a large amount of waste residue at the bottom inside the treatment tank 1, the pushing plate 42 can be repeatedly controlled to move. The pushing plate 42 is pushed to move by the multi-stage cylinder 41, and the rotation of the pushing plate 42 is controlled to clean up the waste liquid and waste residue. When there is still waste residue inside the treatment tank 1, the pushing plate 42 can be pulled up and restored to the initial position, and then in the above-mentioned manner, the movement and rotation of the pushing plate 42 are continuously controlled. Each time, the water baffle 7 can be jacked up, so that the waste residue and waste water flow out. Moreover, when the water baffle 7 moves upward, it will abut against the movable plate 10, indirectly squeezing the spring 9. Therefore, each time after the pushing plate 42 disengages from the water baffle 7, the water baffle 7 will return to the initial position under the action of the spring 9 for subsequent continuous use.
[0042] The centrifuge 43 in this device can select a centrifuge 43 of model SS300.
[0043] It should be noted that the multi-stage cylinder 41 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so no further detailed description will be given.
