Description

Technical Field

[0002] The seed-induced crystallization defluorination device is a device specifically used for removing fluoride ions in water. Its core principle is based on the heterogeneous nucleation of induced crystallization. Through the reaction of specific chemical agents with fluoride ions in the wastewater, the fluoride ions precipitate in a specific crystal form on the surface of the induced crystal carrier, so as to achieve the purpose of removing fluoride ions and recovering resource substances. However, during the working process of the existing device, the precipitated crystals will wrap the surface of the induced crystal carrier until the induced crystal carrier reaches the saturation state. However, the traditional judgment method is to judge the saturation degree of the induced crystal carrier by the staff observing the volume of the induced crystal carrier with the naked eye. The process is relatively troublesome, and there are errors in the human eye observation, resulting in low work efficiency.

The weight of the induced crystal carrier will increase, which will drive the connecting plate and the sliding rod on the upper surface of the connecting plate to move vertically downward. The fixed rod outside the end of the sliding rod will just block the second laser induction module, and it can also remotely alarm to remind the staff to clean up the induced crystal carrier, so as to avoid production interruption caused by saturation, ensure the continuous and stable operation of the production line, significantly improve production efficiency, and at the same time, the automatic detection device of the device can greatly simplify the operation process, reduce the operation difficulty, and relieve the burden of workers.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] A seed-induced crystallization defluorination device includes a reaction barrel 1.

[0022] In this implementation: The seed-induced crystallization defluorination device is a device specifically used to remove fluoride ions in water. Its core principle is based on induced crystallization heterogeneous nucleation. By reacting specific chemical agents with fluoride ions in wastewater, they precipitate in a specific crystal form on the surface of the crystal induction carrier 211, so as to achieve the purpose of removing fluoride ions and recovering resource substances. However, during the working process of the existing device, the precipitated crystals will cover the surface of the crystal induction carrier 211 until the crystal induction carrier 211 reaches a saturated state. However, the traditional judgment method is to judge the saturation degree of the crystal induction carrier 211 by the staff observing the volume of the crystal induction carrier 211 with the naked eye. The process is relatively troublesome, and there are errors in visual observation by the human eye, resulting in low work efficiency. To solve this technical problem, a defluorination component 2 is added on this basis.

[0023] Furthermore:

[0024] As Figures 1 to 4 shown:

[0025] Combining the above content: The defluorination component 2 includes a water injection bucket 21, a connecting pipe 22 and a water pumping assembly 23. The water injection bucket 21 is installed on the outer side of the end of the reaction barrel 1. The outer sides of both ends of several connecting pipes 22 are respectively communicated with the outer side of the end of the water injection bucket 21 and the outer side of the end of the reaction barrel 1. The water pumping assembly 23 is installed on the inner side of the end of the reaction barrel 1. The water pumping assembly 23 communicates several connectors 24 with several connecting pipes 22. One end of the reaction barrel 1 is rotatably connected with an upper cover 25. A sliding rod 26 is slidably connected to the inner side of the end of the upper cover 25. One end of the sliding rod 26 is fixedly connected with a connecting plate 29 on the outer side. The other end of the connecting plate 29 is detachably connected with a fixing rod 27. The outer sides of both ends of a spring 28 are respectively in contact with the outer side of one end of the upper cover 25 and the outer side of the end of the fixing rod 27. A plurality of fixing seats 210 are fixedly connected to the lower surface of the connecting plate 29. A crystallization induction carrier 211 is fixedly connected to the outer side of the end of the fixing seat 210. A plurality of first laser induction modules 212 are annularly installed on the outer side of the end of the fixing seat 210. A second laser induction module 216 is installed on the outer side of the end of the upper cover 25.

[0026] In this embodiment: In the device, the water injection bucket 21 is a hollow annular structure. The water injection bucket 21 is sleeved on the outer side of the end of the reaction bucket 1 and is fixed to the reaction bucket 1. An inlet is provided on the upper surface of one end of the water injection bucket 21. The user can inject fluorine-containing sewage into the interior of the water injection bucket 21 through the water injection port on the outer side of the end of the water injection bucket 21. A plurality of connecting pipes 22 are connected and communicated to the lower surface of the water injection bucket 21. The outer side of the end of the connecting pipe 22 is connected and communicated with the inner side of the end of the reaction bucket 1. When the user needs to treat fluorine-containing wastewater, the pumping assembly 23 is composed of a housing and four water pumps. The four water pumps are installed inside the housing of the pumping assembly 23. The water inlet of the pumping assembly 23 is communicated with a plurality of connecting pipes 22, and the water outlets of the pumping assembly 23 are respectively communicated with a plurality of connectors 24. The user only needs to start the pumping assembly 23. The pumping assembly 23 extracts the fluorine-containing wastewater inside the water injection bucket 21 through a plurality of connecting pipes 22, and then injects the fluorine-containing wastewater into the interior of the reaction bucket 1 through the connectors 24 communicated with the connecting pipes 22. The user can place specific chemical agents on the upper surface of the connecting plate 29 in advance. When the fluorine-containing wastewater submerges the connecting plate 29, the chemical agents on the upper surface of the connecting plate 29 will be dissolved. At this time, the connector 24 continuously injects the fluorine-containing wastewater into the interior of the reaction bucket 1 and continuously contacts the crystal induction carrier 211 on the lower surface of the connecting plate 29. The fluoride ions in the fluorine-containing wastewater react with the chemical agents to form calcium fluoride crystals. These crystals precipitate and grow on the surface of the crystal induction carrier 211, and finally form granular objects with the crystal induction carrier 211 as the center and a high-purity calcium fluoride crystal layer wrapped on the outer layer. The first laser induction module 212 includes a laser emitter and a laser receiver. The laser emitters of three first laser induction modules 212 are installed on the lower surface of the fixed seat 210, and the laser receivers of the first laser induction module 212 are correspondingly installed on the upper surface of the pumping assembly 23. When the surface of the crystal induction carrier 211 is not wrapped with high-purity calcium fluoride crystals, the first laser induction module 212 irradiates vertically downward and cooperates with the receiver on the upper surface of the pumping assembly 23. When the surface of the crystal induction carrier 211 is wrapped with high-purity calcium fluoride crystals to saturation, the volume of the calcium fluoride crystals on the surface of the crystal induction carrier 211 increases, and then the laser trajectory of the first laser induction module 212 will be blocked, so as to give an alarm and timely remind the staff to clean up. At the same time, when the surface of the crystal induction carrier 211 is wrapped with high-purity calcium fluoride crystals, the weight of the crystal induction carrier 211 will increase, and then drive the connecting plate 29, that is, the sliding rod 26 on the upper surface of the connecting plate 29, to move vertically downward, and at the same time compress the spring 28. When all the crystal induction carriers 211 reach the saturation state, at this time, the fixed rod 27 on the outer side of the end of the sliding rod 26 moves downward. The second laser induction module 216 and the corresponding laser receiver of the second laser induction module 216 are installed on the upper surface of the upper cover 25, and just block the optical path of the second laser induction module 216. At the same time, it can also remotely alarm to remind the staff to clean up the crystal induction carrier 211. By monitoring and alarming in time,The device can remind the operator when the crystal induction carrier 211 is saturated, thus avoiding production interruption caused by saturation, ensuring the continuous and stable operation of the production line, significantly improving production efficiency. At the same time, the automatic detection device of the device can greatly simplify the operation process, reduce the operation difficulty and relieve the burden of workers.

[0027] It should be noted that: the purpose of designing the water injection bucket 21 is to make the fluorine-containing wastewater flow upward from the low end inside the reaction bucket 1. By designing the fluorine-containing wastewater to flow upward from the bottom, the pumping assembly 23 can maintain a certain upward flow rate of the fluorine-containing wastewater, making the fluorine-containing wastewater in a fluidized state during operation, and increasing the precipitation efficiency of crystals on the surface of the crystal induction carrier 211.

[0028] Furthermore:

[0029] In an alternative embodiment, a through hole 213 is provided inside the end of the crystal induction carrier 211.

[0030] In this embodiment: the crystal induction carrier 211 has a spherical structure and is hollow inside. The spherical structure of the crystal induction carrier 211 has good fluidity and uniform distribution, which helps the fluoride ions in the wastewater to uniformly contact the crystal induction carrier 211. The spherical crystal induction carrier 211 can provide a relatively smooth surface. When the crystal volume increases, it can more clearly block the laser beam, enabling the photosensor to detect an obvious signal change. Through the through hole 213 at the end of the crystal induction carrier 211, the fluorine-containing wastewater can flow inside the crystal induction carrier 211, further increasing the precipitation efficiency of crystals on the surface and inside the crystal induction carrier 211.

[0031] Furthermore:

[0032] In an alternative embodiment, a flow head 214 is fixedly connected to the outer side of the end of the connecting head 24, and the flow head 214 has a hollow conical structure inside.

[0033] In this embodiment: a flow head 214 is fixedly connected to the outer side of the end of each connecting head 24. The flow head 214 has a hollow conical structure inside. The flow head 214 can more smoothly guide the fluorine-containing wastewater into the reaction bucket 1, thereby improving the fluid transmission efficiency. This design also helps to reduce the turbulence and eddy currents generated during the fluid flow, reduce energy loss, enabling the wastewater to enter the treatment system more smoothly. By reasonably designing the size and angle of the conical structure of the flow head 214, the wastewater can be more evenly distributed inside the reaction bucket 1 during the treatment process, improving the treatment effect and efficiency.

[0034] Furthermore:

[0035] In an alternative embodiment, a scale 215 is provided on the outer side of the end of the sliding rod 26.

[0036] In this embodiment: A scale 215 is provided on the outer side of the end of the sliding rod 26, enabling the user to observe the descending degree of the sliding rod 26 in real time, and thus the treatment progress of the fluorine-containing wastewater inside the reaction barrel 1 can be deduced, facilitating the staff to grasp the working rhythm and enhancing the user experience.

[0037] Working principle: In this device, the water injection bucket 21 is a hollow annular structure. The water injection bucket 21 is sleeved on the outer side of the end of the reaction barrel 1 and is fixed to the reaction barrel 1. An inlet is provided on the upper surface of one end of the water injection bucket 21. Users can inject fluorine-containing sewage into the interior of the water injection bucket 21 through the water injection port on the outer side of the end of the water injection bucket 21. A number of connecting pipes 22 are connected and communicated to the lower surface of the water injection bucket 21. The outer side of the end of the connecting pipe 22 is connected and communicated with the inner side of the end of the reaction barrel 1. When users need to treat fluorine-containing wastewater, the pumping assembly 23 is composed of a housing and four water pumps. The four water pumps are installed inside the housing of the pumping assembly 23. The water inlet of the pumping assembly 23 is communicated with a plurality of connecting pipes 22, and the water outlets of the pumping assembly 23 are respectively communicated with a plurality of connectors 24. Users only need to start the pumping assembly 23. The pumping assembly 23 extracts the fluorine-containing wastewater inside the water injection bucket 21 through a plurality of connecting pipes 22, and then injects the fluorine-containing wastewater into the interior of the reaction barrel 1 through the connectors 24 communicated with the connecting pipes 22. Users can place specific chemical agents on the upper surface of the connecting plate 29 in advance. When the fluorine-containing wastewater submerges the connecting plate 29, the chemical agents on the upper surface of the connecting plate 29 will be dissolved. At this time, the connector 24 continuously injects the fluorine-containing wastewater into the interior of the reaction barrel 1 and continuously contacts the crystal induction carrier 211 on the lower surface of the connecting plate 29. The fluoride ions in the fluorine-containing wastewater react with the chemical agents to form calcium fluoride crystals. These crystals precipitate and grow on the surface of the crystal induction carrier 211, and finally form granular objects with the crystal induction carrier 211 as the center and a high-purity calcium fluoride crystal layer wrapped on the outer layer. The first laser induction module 212 includes a laser emitter and a laser receiver. The laser emitters of three first laser induction modules 212 are installed on the lower surface of the fixed seat 210, and the laser receivers of the first laser induction module 212 are correspondingly installed on the upper surface of the pumping assembly 23. When the surface of the crystal induction carrier 211 is not wrapped with high-purity calcium fluoride crystals, the first laser induction module 212 irradiates vertically downward and cooperates with the receiver on the upper surface of the pumping assembly 23. When the surface of the crystal induction carrier 211 is wrapped with high-purity calcium fluoride crystals to saturation, the volume of the calcium fluoride crystals on the surface of the crystal induction carrier 211 increases, which will block the laser trajectory of the first laser induction module 212, and then an alarm can be given to timely remind the staff to clean. At the same time, when the surface of the crystal induction carrier 211 is wrapped with high-purity calcium fluoride crystals, the weight of the crystal induction carrier 211 will increase, which will drive the connecting plate 29, that is, the sliding rod 26 on the upper surface of the connecting plate 29 to move vertically downward, and at the same time compress the spring 28. When multiple crystal induction carriers 211 reach the saturated state, at this time, the fixed rod 27 on the outer side of the end of the sliding rod 26 moves downward. The second laser induction module 216 and the corresponding laser receiver of the second laser induction module 216 are installed on the upper surface of the upper cover 25, and just block the optical path of the second laser induction module 216. At the same time, it can also remotely alarm to remind the staff to clean the crystal induction carrier 211. By timely monitoring and alarming,The device can remind the operator when the crystallization induction carrier 211 is saturated, thus avoiding production interruption caused by saturation, ensuring the continuous and stable operation of the production line, significantly improving production efficiency. At the same time, the automatic detection device of the device can greatly simplify the operation process, reduce the operation difficulty, and relieve the burden on workers. The crystallization induction carrier 211 is of a spherical structure and hollow inside. The spherical structure of the crystallization induction carrier 211 has good fluidity and uniform distribution, which helps the fluoride ions in the wastewater to uniformly contact the crystallization induction carrier 211. The spherical crystallization induction carrier 211 can provide a relatively smooth surface. When the crystallization volume increases, it can more clearly block the laser beam, enabling the photosensor to detect an obvious signal change. Through the through-hole 213 at the end of the crystallization induction carrier 211, the fluoride-containing wastewater can flow inside the crystallization induction carrier 211, further increasing the precipitation efficiency of the crystal on the surface and inside of the crystallization induction carrier 211. A flow head 214 is fixedly connected to the outer side of the end of each connector 24. The flow head 214 is a conical structure with a hollow inside. The flow head 214 can more smoothly guide the inflow of the fluoride-containing wastewater into the reaction barrel 1, thereby improving the efficiency of fluid transmission. This design also helps to reduce the turbulence and eddy current generated during the fluid flow, reduce energy loss, and enable the wastewater to enter the treatment system more smoothly. By reasonably designing the size and angle of the conical structure of the flow head 214, the wastewater can be more evenly distributed inside the reaction barrel 1 during the treatment process, improving the treatment effect and efficiency. A scale 215 is provided on the outer side of the end of the sliding rod 26, enabling the user to observe the descending degree of the sliding rod 26 in real time, and then the treatment progress of the fluoride-containing wastewater inside the reaction barrel 1 can be estimated, facilitating the staff to grasp the working rhythm and enhancing the user experience.
