Description

Technical Field

[0001] This invention relates to the field of organic wastewater treatment technology, specifically to an advanced oxidation pretreatment device for rare earth extraction organic wastewater. Background Technology

[0002] Rare earth elements are widely used in petroleum, chemical, and metallurgical fields. After rare earth mines are mined, two methods are generally used: hydrometallurgy and pyrometallurgy. Hydrometallurgy is a chemical metallurgical method in which the entire process is mostly carried out in solutions and solvents. For example, the decomposition of rare earth concentrates, the separation and extraction of rare earth oxides, rare earth compounds, and single rare earth metals are carried out using chemical separation processes such as precipitation, crystallization, redox, solvent extraction, and ion exchange.

[0003] In hydrometallurgical processes, the large amount of solvent involved generates substantial amounts of organic wastewater after extraction. This wastewater pollutes water sources and requires advanced oxidation treatment to meet discharge standards. Advanced oxidation treatment utilizes strong oxidants to oxidize and decompose pollutants in wastewater, thus purifying it. It has become an important means of treating biologically recalcitrant organic pollutants. Rare earth organic wastewater contains difficult-to-treat organic components, necessitating advanced oxidation treatment. This technology utilizes strong oxidizing groups—hydroxyl radicals—generated during the chemical reaction and a series of chain reactions to oxidize and decompose organic matter into smaller molecules, ultimately degrading it into CO2, H2O, and inorganic salts. Hydroxyl radicals possess extremely strong oxidizing power, effectively removing recalcitrant and highly stable organic matter from water.

[0004] Before advanced oxidation treatment, waste liquid needs to be collected for pretreatment. Therefore, a container is used to hold the waste liquid. However, existing pretreatment equipment cannot detect and sample the waste liquid in a timely manner. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1.

The top of the sampling tube 11 is connected to the bottom of the sampling box 3.

[0034] A sealing strip 13 is provided at the connection between the box body 1 and the sealing box 5. A movable plate 14 is provided on the side of the sealing strip 13 away from the sealing box 5. A sliding groove 15 is provided at the connection between the box body 1 and the movable plate 14. A first limiting sliding groove 16 is provided on the top of the movable plate 14. A first limiting slider 17 is provided inside the first limiting sliding groove 16. The first limiting slider 17 is fixedly connected to the box body 1.

[0035] A connecting block 18 is provided on the side of the movable plate 14 away from the sealing strip 13. A starting strip 19 is connected to the bottom of the connecting block 18. A threaded rod 20 passes through the end of the starting strip 19 near the door panel 6. A threaded rod groove 21 is provided at the connection between the starting strip 19 and the threaded rod 20.

[0036] The two ends of the movable plate 14 are provided with a second limiting groove 23 at the connection between them and the housing 1. The second limiting groove 23 is provided with a second limiting slider 22. The second limiting slider 22 is connected to the housing 1. The end of the threaded rod 20 away from the starting bar 19 is provided with a first gear 24. A second gear 25 is connected to one side of the first gear 24. A wheel 26 is connected to the side of the second gear 25 away from the housing 1. A sealing box 27 is installed on one side of the bottom of the housing 1. The first gear 24 and the second gear 25 are provided inside the sealing box 27. The wheel 26 connected to the second gear 25 is located on the outside of the sealing box 27.

[0037] Specifically, the conduit 8 is a "T" tube, and the top of the conduit 8 is connected to the sampling box 3, while the bottom two ends are respectively connected to the outside of the sealing box 5. Two sets of water valves 10 are installed on the bottom two ends of the conduit 8.

[0038] In this embodiment, the conduit 8 can connect two spaces in the box 1 that are divided by the partition 2, so that the sampling box 3 can take samples from the two spaces separately through the conduit 8.

[0039] Specifically: one end of the drain pipe 9 is vertically connected to the middle of the bottom of the conduit 8, and a valve is separately installed on the end of the drain pipe 9 away from the drain pipe 9.

[0040] In this embodiment, the drain pipe 9 can drain the sample liquid inside the sampling box 3, which is convenient for sampling and also convenient for secondary sampling.

[0041] Specifically, the sealing mechanism consists of sealing strip 13, moving plate 14, slide groove 15, first limiting slide groove 16, first limiting slider 17, connecting block 18, starting strip 19, threaded rod 20, threaded rod slide groove 21, second limiting slider 22, second limiting slide groove 23, and first gear 24. There are two sets of sealing mechanisms, and the two sets of sealing mechanisms are symmetrically distributed on both sides of the bottom of the sealing box 5.

[0042] In this embodiment, the two sets of sealing mechanisms allow the bottom of the sealing box 5 to be more tightly connected to the box body 1, and also make the two sides of the space divided by the partition 2 more independent, thus preventing communication from the bottom of the sealing box 5.

[0043] Specifically: the edge of the sealing strip 13 is fixedly connected to the housing 1, and the sealing strip 13 is made of elastic material.

[0044] In this embodiment, the sealing strip 13 is fixedly connected to the edge of the box 1, and can protrude in the middle after the moving plate 14 moves without separating from the edge of the box 1, so as to avoid gaps between the box 1 and the sealing strip 13, which would lead to a decrease in sealing performance.

[0045] Specifically: the connection between the movable plate 14 and the connecting block 18 is a sloping structure, and the width of the movable plate 14 at the end near the first gear 24 is smaller than the width of the movable plate 14 at the end away from the first gear 24.

[0046] In this embodiment, the connection between the movable plate 14 and the connecting block 18 is a sloping structure, which can push the movable plate 14 to the vertical side when the connecting block 18 moves.

[0047] Specifically: the first limiting groove 16 is evenly opened on the top of the moving plate 14, and the top cross section of the moving plate 14 where the first limiting groove 16 is located forms a regular rack structure.

[0048] In this embodiment: multiple sets of first limiting slide grooves 16 and The sliding of the first limit slider 17 can improve the stability of the translation of the moving plate 14, allowing the moving plate 14 to push the sealing strip 13 outward evenly, thereby increasing the sealing effect of the sealing strip 13.

[0049] Specifically, the shape, size, and number of positions of the first limiting slider 17 correspond to the shape, size, and number of positions of the first limiting groove 16.

[0050] In this embodiment, the sliding of the first limiting slider 17 and the first limiting groove 16 allows the moving plate 14 to move vertically toward the sealing box 5 when pushed by the connecting block 18, thus preventing the moving plate 14 from shaking and increasing the stability of the movement of the moving plate 14.

[0051] Specifically: the threads of the two sets of threaded rods 20 are in opposite directions.

[0052] In this embodiment, the opposite thread directions of the two sets of threaded rods 20 enable the threaded rods 20 driven by the rotation of the two sets of first gears 24 on both sides to correctly align the movement directions of the two sets of starting bars 19 when the second gear 25 drives the first gears 24 on both sides to rotate.

[0053] Working Principle: When using this advanced oxidation pretreatment equipment for rare earth extraction of organic wastewater, the wastewater to be treated first enters the interior of tank 1. Tank 1 is divided into two spaces by partition 2, allowing for simultaneous treatment of two waste liquids. During treatment, if it is necessary to sample one side of the waste liquid, the water valve 10 of the conduit 8 on that side can be opened. After the water valve 10 is opened, the waste liquid on the same side of tank 1 will enter the sampling box 3 through conduit 8. The viewing window 4 on the side of the sampling box 3 allows personnel to easily observe the wastewater. The internal liquid level is observed, and then the water valve 10 on the same-side conduit 8 can be closed. The waste liquid is then sampled through the sampling tube 11 inside the sampling box 3, avoiding the need to open the entire cover 28 of the device for sampling. A detector 12 can be inserted into the sampling tube 11 to achieve real-time detection of the waste liquid inside the sampling box 3. After detection, the water valve 10 on the drain pipe 9 can be opened to drain the waste liquid from the sampling box 3, thus emptying the interior of the sampling box 3 and facilitating the detection and sampling of waste liquid inside the other side of the box 1. It is detachable. When the sealing box 5 at the bottom of the sampling box 3 contacts the bottom of the box body 1, the wheel 26 on the sealing box 27 can be rotated. The rotation of the wheel 26 drives the second gear 25 to rotate. The rotation of the second gear 25 drives the two sets of first gears 24 on both sides. The first gears 24 drive the connected threaded rods 20 respectively. When the threaded rods 20 rotate, the threaded structure on the surface can push the starting bar 19 connected to it to one side. When the starting bar 19 moves, it drives the connecting block 18 at the top to move. The connection between the connecting block 18 and the moving plate 14 is an inclined surface. When the connecting block 18 moves... At the same time, the moving plate 14 will be pushed in the direction perpendicular to the moving direction. The top of the moving plate 14 is provided with a first limiting groove 16. The first limiting groove 16 will also slide with the first limiting slider 17 of the box body 1, further increasing the stability of the moving plate 14. When the moving plate 14 moves, the sealing strip 13 on one side can protrude outward evenly. When both sets of sealing strips 13 protrude outward at the same time, they can clamp the middle sealing box 5, thereby increasing the sealing performance of the connection between the sealing box 5 and the box body 1, and preventing the two waste liquids separated by the partition 2 from contacting each other. This is the usage process of the present invention.

[0054] Although the present invention 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 invention should be included within the protection scope of the present invention.
