Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wastewater treatment, in particular to a device for extracting and recovering calcium fluoride from wastewater. Background Art
[0002] The extraction and recovery device of calcium fluoride in wastewater is mainly used to separate and recover calcium fluoride from fluoride-containing wastewater to reduce environmental pollution and realize resource reuse. Calcium fluoride is an important industrial raw material and is widely used in aluminum smelting, chemical synthesis and water treatment. In the process of extracting calcium fluoride from wastewater, adding calcium salt to the wastewater can be used to remove fluoride, especially fluoride ions. In wastewater treatment, adding calcium salts such as calcium chloride or calcium sulfate can react with fluoride ions in wastewater to form insoluble calcium fluoride, thereby realizing the extraction of calcium fluoride and the removal of fluoride ions. Since the extracted calcium fluoride is still inside the wastewater, it is necessary to perform a discharge separation operation between calcium fluoride and wastewater.
[0003] In the related art, during the use of a calcium fluoride extraction and recovery device, a filter screen is generally installed at the bottom of the extraction and recovery device to perform discharge separation between calcium fluoride and wastewater, so that the device can be used.
[0004] However, during the current use of calcium fluoride extraction and recovery equipment, since the filter can only filter and separate calcium fluoride from wastewater, the filtered calcium fluoride remains on the surface of the filter. Workers need to use a separate recovery tool to recover the calcium fluoride on the surface of the filter, which makes the recovery of calcium fluoride more complicated and affects the convenience and efficiency of calcium fluoride extraction and recovery.

[0030] Reference Figure 1-Figure 4 The utility model provides a technical solution: a device for extracting and recovering calcium fluoride from wastewater, comprising an extraction tank 1 and an extraction, separation and discharge mechanism. A motor 2 is installed on the top of the extraction tank 1, a mixing shaft 3 connected to the motor 2 is installed inside the extraction tank 1, and a discharge pipe 4 is installed at the bottom of the extraction tank 1. The discharge, filtration and separation work can be performed between the calcium fluoride formed after the reaction inside the extraction tank 1 and the wastewater, while providing a medium for the filtered calcium fluoride to be discharged out of the extraction tank 1 for recovery, thereby improving the extraction, discharge and recovery convenience and operation efficiency of the extraction tank 1.
[0031] Reference Figure 1-Figure 4 In a preferred embodiment, the extraction, separation and discharge mechanism includes a separation seat 5, which is movably connected to the bottom of the extraction tank 1. A separation rod 6 is fixedly connected to the left side of the top of the separation seat 5. A discharge port 8 is opened at the bottom of the separation seat 5 and the left side of the extraction tank 1. The bottom of the left side of the extraction tank 1 is fixedly connected to a discharge pipe 9 located outside the discharge port 8. The separation stabilization mechanism is fixedly connected to the top of the left side of the inner wall of the extraction tank 1. When the wastewater inside the extraction tank 1 is reacted with calcium salt to form calcium fluoride, the wastewater after the reaction inside the extraction tank 1 is first discharged from the extraction tank 1 through the discharge pipe 4. Since the separation seat 5 is hollow, the separation seat 5 performs discharge and separation work between the wastewater and the calcium fluoride. When the wastewater inside the extraction tank 1 is discharged, the separation seat 5 is rotated by the separation rod 6 to drive the discharge port 8 moves to align with the discharge pipe 9, so that the calcium fluoride filtered and retained inside the separation seat 5 is discharged from the extraction tank 1 through the discharge port 8 and the discharge pipe 9 for recovery operation. The separation stabilization mechanism includes a stabilization seat 10, a stabilization port 11 and a stabilization ring 12.

The inner side of the stabilization ring 12 is fixedly connected to the surface of the separation rod 6.

[0032] Reference Figure 2-Figure 4In a preferred embodiment, a positioning plate 13 is movably connected to the top of the separation rod 6, and positioning columns 14 are fixedly connected to both sides of the bottom of the positioning plate 13. The separation rod 6 and the separation seat 5 can be stably positioned by the stabilizing seat 10, thereby avoiding the situation where the stabilizing force of the separation rod 6 and the separation seat 5 is insufficient when the stabilizing seat 10 is used, thereby improving the stabilizing effect of the stabilizing seat 10. Positioning grooves 15 are provided on both sides of the top of the stabilizing seat 10, which are located outside the stabilizing mouth 11. The bottom of the positioning column 14 is located inside the positioning groove 15, which can provide the positioning column 14 with a force application space for insertion and positioning, thereby improving the positioning effect of the positioning column 14.
[0033] Reference Figure 2-Figure 4 In a preferred embodiment, a lifting groove 16 is provided at the top of the separation rod 6, and a lifting rod 17 is movably connected inside the lifting groove 16. The top of the lifting rod 17 is fixedly connected to the bottom of the positioning plate 13, so that the positioning plate 13 and the separation rod 6 can be lifted and lowered. The connection effect of the positioning plate 13 and the separation rod 6 is improved, and a limiting groove 18 is provided at the bottom of the inner wall of the lifting groove 16. The limiting groove 18 is movably connected to the limiting plate 19. The top of the limiting plate 19 is fixedly connected to the bottom of the lifting rod 17, so that the lifting and limiting work can be performed between the lifting rod 17 and the lifting groove 16, thereby improving the lifting connection stability of the lifting rod 17.

A medium for closing and sealing the discharge pipe 9 can be provided to the user, thereby improving the convenience of closing and sealing the discharge pipe 9. A card groove 22 is provided on the inner wall of the closing sleeve 21, and a snap ring 23 is movably connected to the inside of the card groove 22. The inner side of the snap ring 23 is fixedly connected to the surface of the discharge pipe 9, which can perform closed card connection and stable work between the closing sleeve 21 and the discharge pipe 9, thereby improving the closing stability of the closing sleeve 21.
[0035] Specifically, the working process or working principle of the calcium fluoride extraction and recovery device in wastewater is as follows: when in use, after the wastewater inside the extraction tank 1 is reacted with calcium salt to form calcium fluoride, the discharge pipe 4 is first opened to discharge the wastewater after the reaction inside the extraction tank 1 through the discharge pipe 9. At this time, since the separation seat 5 is hollow, the separation seat 5 performs discharge and separation work between the wastewater and the calcium fluoride, and retains the calcium fluoride inside the separation seat 5 to prepare for subsequent discharge and recovery of calcium fluoride. When the wastewater inside the extraction tank 1 is discharged, the handheld positioning plate 13 drives the positioning column 14 to move upward and out of the positioning groove 15. At this time, the lifting column follows the positioning plate 13 to drive the limit plate 19 to move inside the limit groove 18, and performs lifting and lowering connection and limiting work between the positioning plate 13 and the separation rod 6, and drives the separation seat 5 to rotate through the positioning plate 13 and the separation rod 6. At this time, the stabilizing ring 12 follows The separation rod 6 moves at the bottom of the stabilizing seat 10 to cooperate with the stabilizing port 11, and performs position stabilization work on the separation rod 6 and the separation seat 5 during the rotation process. When the separation rod 6 moves to the front side inside the stabilizing port 11, it means that the separation seat 5 drives the discharge port 8 to move and align with the discharge pipe 9. At this time, the handheld positioning plate 13 drives the positioning column 14 to move downward into the positioning groove 15 to position and stabilize the moved separation rod 6 and the separation seat 5. Subsequently, the handheld closing sleeve 21 drives the closing column 20 to move to the left to disengage from the discharge pipe 9 and open the discharge pipe 9, so that the calcium fluoride filtered and retained inside the separation seat 5 is discharged from the extraction tank 1 through the discharge port 8 and the discharge pipe 9 for recovery operation. In this process, the separation plate 7 can be driven to rotate by the motor 2 in cooperation with the mixing shaft 3 to discharge and scrape the calcium fluoride inside the separation seat 5, so that the calcium fluoride inside the separation seat 5 is more thoroughly discharged from the extraction tank 1.
[0036] It should be noted that the extraction tank 1, motor 2, mixing shaft 3 and discharge pipe 4 are all devices or equipment existing in the prior art, or devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
