DETAILED DESCRIPTION

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] See also Figure 1 , a wastewater treatment device for rubidium and cesium salt production provided by the present invention is now described. A wastewater treatment device for rubidium and cesium salt production includes a sedimentation tank 11, a neutralization tank 21 and a filter tank 31 which are connected in sequence. The sedimentation tank 11 is provided with a first stirring mechanism and a first feeding port, and the first feeding port is used to add chemical reagents so that the metal ions in the sedimentation tank 11 undergo a precipitation reaction. The neutralization tank 21 is provided with a second stirring component and a second feeding port, and the second feeding port is used to add chemical reagents so that the acid radical ions in the neutralization tank 21 undergo a neutralization reaction. The filter box 31 is provided with a filter component, and the filter component is used to filter solid particulate impurities.

[0050] For details, see Figure 1 The sedimentation tank 11 , the neutralization tank 21 and the filter tank 31 are connected by a pipeline, and a pump body for extracting wastewater is arranged on the pipeline, so as to realize the flow of wastewater along the sedimentation tank 11 , the neutralization tank 21 and the filter tank 31 .

[0051] First, a chemical reagent is added through the first feeding port in the sedimentation box 11 to cause a precipitation reaction of the metal ions in the wastewater, which can convert the metal ions into solid precipitates for subsequent precipitation separation. The first stirring mechanism can fully mix the chemical reagent and the wastewater, so that the metal ions in the wastewater react more fully and the metal ions are removed more thoroughly.

[0052] Then, an alkaline chemical reagent is added into the neutralization box 21 through the second feeding port to cause a neutralization reaction of the acid ions. The neutralization reaction can adjust the pH of the wastewater to make it closer to neutrality to meet the requirements of subsequent treatment. The second stirring component can fully mix the alkaline chemical reagent and the wastewater, so that the acid ions in the wastewater fully react and the acid ions are removed more thoroughly.

[0053] Finally, the wastewater enters the filter box 31, and the filter assembly filters out the solid particle impurities present in the wastewater, thereby completing the multi-stage treatment of the wastewater, improving the overall effect of the wastewater treatment, and improving the treatment efficiency.

[0054] In some embodiments, see Figure 2 and Figure 3 The first stirring mechanism includes a first motor 12, a first stirring shaft 13, a folding plate 14 and an opening and closing assembly. The first motor 12 is fixedly arranged at the top of the sedimentation box 11. The first stirring shaft 13 is vertically rotatably arranged on the sedimentation box 11 and is connected to the output end of the first motor 12. The folding plate 14 is fixedly arranged on the first stirring shaft 13. The folding plate 14 has a first state and a second state. In the first state, the inner cavity of the sedimentation box 11 is connected up and down, and the folding plate 14 can stir the wastewater in the inner cavity of the sedimentation box 11. In the second state, the folding plate 14 is used to separate the inner cavity of the sedimentation box 11 to separate the sediment and the wastewater. The opening and closing assembly is arranged on the sedimentation box 11, and is used to control the folding plate 14 to switch between the first state and the second state.

[0055] Specifically, when chemical reagents for treating metal ions are added into the sedimentation tank 11, the folding plate 14 is in the first state. In the first state, the folding plate 14 can rotate with the first stirring shaft 13, so as to fully stir the wastewater in the sedimentation tank 11, promote the wastewater and the chemical reagents to be fully mixed, accelerate the precipitation reaction of metal ions, and improve the precipitation efficiency. At the same time, during the sedimentation process, the folding plate 14 remains in the first state until the sedimentation is completed, the first stirring shaft 13 is stationary, and the folding plate 14 is switched to the second state. The folding plate 14 separates the sediment in the sedimentation tank 11 at the bottom of the sedimentation tank 11, so that the sediment and wastewater in the sedimentation tank 11 can be effectively separated, and the sediment is prevented from being pumped into the neutralization tank 21 along with the wastewater by the pump body.

[0056] In some embodiments, see Figure 2 and Figure 4 When the folding plate 14 is in the first state, the folding plate 14 unfolds to form a first plane, and the first plane is parallel to the first stirring shaft 13, so that the folding plate 14 rotates with the first stirring shaft 13 to stir the wastewater.

[0057] See also Figure 3 and Figure 5When the folding plate 14 is in the second state, the folding plate 14 folds to form a second plane, and the second plane is perpendicular to the first stirring shaft 13, so that the folding plate 14 divides the internal space of the sedimentation tank 11 into a first space 111 for accommodating wastewater and a second space 112 for accommodating sediment, and the first space 111 is located above the second space 112, and the first space 111 is connected to the neutralization tank 21.

[0058] See also Figure 2 and Figure 4 When the folding plate 14 is in the first state, the first plane formed by the folding plate 14 is parallel to the first stirring shaft 13, so that the folding plate 14 can disturb the wastewater to the greatest extent during the stirring process, ensuring that the wastewater can be fully stirred in each area of ​​the sedimentation tank 11, so that the chemical reagents and the metal ions in the wastewater are fully in contact, thereby improving the completeness of the precipitation reaction. At the same time, the folding plate 14 in the first state is arranged vertically, so that the sediment is not easy to fall on the folding plate 14 when it settles, reducing the obstruction to the sediment when it settles, which is conducive to the sediment falling to the bottom of the sedimentation tank 11.

[0059] See also Figure 3 and Figure 5 When the folding plate 14 is in the second state, the second plane formed by the folding plate 14 is perpendicular to the first stirring shaft 13, and the internal space of the sedimentation tank 11 is divided into a first space 111 located at the top and a second space 112 located at the bottom. The water outlet of the sedimentation tank 11 is close to the second plane and located above the second plane, so that the first space 111 is connected with the neutralization tank 21, ensuring that the wastewater after sedimentation can smoothly enter the neutralization tank 21 for the next step of treatment. At the same time, the folding plate 14 also blocks the sediment, preventing the sediment from being pumped into the neutralization tank 21 by the pump body and affecting the subsequent treatment process.

[0060] In some embodiments, see Figure 4 and Figure 5 The folding plate 14 includes a connecting portion 141, two first folding portions 1421, two second folding portions 1422 and a collar 143. The connecting portion 141 is fixedly arranged at the bottom of the first stirring shaft 13 and is perpendicular to the first stirring shaft 13. The two first folding portions 1421 are hinged on both sides of the connecting portion 141, respectively. The two second folding portions 1422 correspond to the two first folding portions 1421 one by one and are hinged to the two first folding portions 1421, respectively. The collar 143 is slidably arranged on the first stirring shaft 13, and the two second folding portions 1422 are hinged on both sides of the collar 143, respectively. In the first state, the collar 143 can rotate with the first stirring shaft 13, and in the second state, the collar 143 can be stationary with the first stirring shaft 13.

[0061] When the first folding portion 1421 and the second folding portion 1422 are parallel to the first stirring shaft 13, the folding plate 14 is in the first state. When the first folding portion 1421 and the second folding portion 1422 are perpendicular to the first stirring shaft 13, the folding plate 14 is in the second state.

[0062] Specifically, when the folding plate 14 is in the first state, the collar 143 is located at the upper end of the first stirring shaft 13, the two first folding portions 1421 are attached to each other, and the two second folding portions 1422 are attached to each other. At the same time, the first folding portion 1421 and the second folding portion 1422 are coplanar, so that the two first folding portions 1421 and the two second folding portions 1422 form a first plane parallel to the first stirring shaft 13.

[0063] When the folding plate 14 is in the second state, the ring 143 is located at the lower end of the first stirring shaft 13, and the first folding portion 1421 and the second folding portion 1422 are attached to each other. At the same time, the two first folding portions 1421 are coplanar, and the two second folding portions 1422 are coplanar, which makes the two first folding portions 1421 and the two second folding portions 1422 form a second plane perpendicular to the first stirring shaft 13.

[0064] When the ring 143 moves along the axis of the first stirring shaft 13, the first folding portion 1421 and the second folding portion 1422 can rotate relative to each other, thereby realizing flexible switching of the folding plate 14 between the first state for stirring and the second state for separation, ensuring the effective realization of the functions of the sedimentation box 11 in different working stages, and improving the working efficiency and practicality of the sedimentation box 11.

[0065] In some embodiments, see Figure 6 A slide groove 131 is provided on the first stirring shaft 13 along the axial direction, and a slider 1431 slidably connected to the slide groove 131 is fixedly provided on the collar 143 .

[0066] The sliding connection between the slide groove 131 and the slider 1431 provides a guide for the axial movement of the ring 143 on the first stirring shaft 13, ensuring that the ring 143 will not deviate or shake during the movement, thereby stably driving the folding plate 14 to unfold or fold, ensuring the accuracy and reliability of the switching of the folding plate 14 between the first state and the second state, and facilitating the stable realization of the stirring and separation functions in the sedimentation box 11.

[0067] Meanwhile, when the first stirring shaft 13 rotates, the sleeve ring 143 can be driven to rotate together through the slide groove 131 and the slider 1431 , thereby driving the first folding portion 1421 and the second folding portion 1422 to rotate together to stir the wastewater.

[0068] In some embodiments, see Figure 4 and Figure 5 The opening and closing assembly includes a rotating ring 15, a connecting rod 16 and an electric cylinder 17. The rotating ring 15 is rotatably set on the sleeve 143, and the rotation axis coincides with the rotation axis of the sleeve 143. When the first stirring shaft 13 rotates, the rotating ring 15 and the sleeve 143 rotate relative to each other, and when the first stirring shaft 13 is stationary, the rotating ring 15 and the sleeve 143 are relatively stationary. The connecting rod 16 is fixedly set on the rotating ring 15, and the connecting rod 16 extends vertically upward and passes through the top surface of the sedimentation box 11. The electric cylinder 17 is fixedly set on the top of the sedimentation box 11, and the telescopic end is fixed to the connecting rod 16. When the electric cylinder 17 is started, the sleeve 143 rises or falls to switch the folding plate 14 between the first state and the second state.

[0069] The rotating connection between the rotating ring 15 and the sleeve 143 allows the rotating ring 15 to not rotate when the sleeve 143 rotates with the first stirring shaft 13, thereby ensuring that the connecting rod 16 and the electric cylinder 17 will not be twisted. When the electric cylinder 17 is started, the telescopic action of the telescopic end of the electric cylinder 17 is transmitted to the rotating ring 15 through the connecting rod 16, thereby driving the sleeve 143 to rise or fall. The sleeve 143 is controlled to move up and down by the electric cylinder 17, and the sleeve 143 drives the first folding part 1421 and the second folding part 1422 to rotate, thereby controlling the switching of the folding plate 14 between the first state and the second state, which is closely coordinated with the sedimentation and separation working process in the sedimentation box 11. When stirring is required, the folding plate 14 is in the first state of unfolding, and when the sediment and wastewater need to be separated, the folding plate 14 is switched to the second state of folding, thereby improving the automation and working efficiency of the entire sedimentation box 11.

[0070] In some embodiments, see Figure 7 The second stirring assembly includes a second motor 22, a second stirring shaft 23 and a stirring blade 24. The second motor 22 is fixedly arranged on the neutralization box 21. The second stirring shaft 23 is vertically rotatably arranged on the neutralization box 21 and connected to the output end of the second motor 22. The stirring blade 24 is fixedly arranged on the second stirring shaft 23.

[0071] The second motor 22 is fixed on the neutralization box 21 as a power source to drive the second stirring shaft 23 to rotate. The stirring blade 24 is fixed on the second stirring shaft 23 and rotates with the rotation of the second stirring shaft 23. The stirring blade 24 stirs the wastewater in the neutralization box 21, so that the neutralization reagent added through the second feeding port in the neutralization box 21 can be fully mixed with the wastewater, ensuring that the neutralization reaction of the acid radical ions in the wastewater can be carried out quickly and evenly, improving the efficiency of the neutralization reaction, and creating favorable conditions for the subsequent further treatment of the wastewater.

[0072] In some embodiments, see Figure 8The filter assembly includes a coarse sand filter element 32, a fine sand filter element 33 and an activated carbon filter element 34 which are sequentially arranged in the filter box 31 along the process direction of the wastewater treatment. It should be understood that the coarse sand filter element 32, the fine sand filter element 33 and the activated carbon filter element 34 in the filter box 31 can be disassembled and replaced.

[0073] The coarse sand filter element 32 first filters the larger particles of impurities in the wastewater and intercepts the larger solid particles, which may be the precipitation produced by the incomplete precipitation of the sedimentation tank 11 or the reaction of the neutralization tank 21. Then the wastewater passes through the fine sand filter element 33 to further filter out the smaller particles of impurities. Finally, it passes through the activated carbon filter element 34. The porous structure of the activated carbon can absorb tiny impurities such as organic matter and pigments in the wastewater. This multi-stage filter element setting filters the wastewater layer by layer, which can more thoroughly remove various impurities in the wastewater, improve the filtering effect, and make the treated wastewater reach higher water quality standards.

[0074] In some embodiments, see Figure 1 and Fig. 9 The water outlet of the filter box 31 is connected to a water storage tank 41, which is used to store treated wastewater. The filter box 31 and the water storage tank 41 are connected by a pipeline, and a pump body for extracting wastewater is provided on the pipeline, so that the wastewater enters the water storage tank 41. The water storage tank 41 is provided with a drain pipe for discharging wastewater, which is not shown in the figure. The bottom end of the water storage tank 41 is connected to a sampling tube 42, which is made of transparent tempered glass. The water inlet end of the sampling tube 42 is provided with a first valve 431, and the water outlet end is provided with a second valve 432.

[0075] After the wastewater treatment is completed, the second valve 432 is closed and the first valve 431 is opened, so that the wastewater enters the sampling tube 42. After the sampling tube 42 is filled with wastewater, the first valve 431 is closed and the second valve 432 is opened, so that the wastewater in the sampling tube 42 is taken out for detection. The wastewater in the water storage tank 41 is sampled through the sampling tube 42, which avoids the situation that the water pressure is too high during direct sampling and causes wastewater splashing. According to the test results, the wastewater in the water storage tank 41 can be re-introduced into the sedimentation tank 11, the neutralization tank 21 and the filter tank 31, so that the wastewater is treated again.

[0076] In some embodiments, see Figure 1 The bottom of the sedimentation box 11 is conical, and the conical structure helps the sediment to gather at the bottom of the sedimentation box 11. During the sedimentation process, due to the effect of gravity, the sediment will gradually settle to the bottom of the sedimentation box 11. The conical bottom can guide the sediment to gather at the lowest point, which is convenient for the subsequent effective separation of the sediment and the wastewater through the folding plate 14, thereby improving the sedimentation and separation efficiency of the sedimentation box 11.

[0077] A slag discharge bucket for discharging sediment is arranged at the bottom end of the sedimentation box 11, and a cover for closing the slag discharge bucket is arranged on the slag discharge bucket.

[0078] In summary, the present invention provides a wastewater treatment device for rubidium and cesium salt production. Compared with the prior art, the sedimentation tank 11 is the first step in the wastewater treatment process. Chemical reagents are added to the sedimentation tank 11 through the first feeding port, and stirred by the first stirring mechanism, so that the chemical reagents and metal ions in the wastewater fully react, so that the metal ions form a precipitate that is easy to settle. The wastewater after precipitation enters the neutralization tank 21, and an alkaline chemical reagent is added to the neutralization tank 21 through the second feeding port, and stirred by the second stirring component, so that the alkaline chemical reagent and the acid radical ions fully react, so that the wastewater reaches or approaches neutrality. Finally, the wastewater enters the filter box 31, and the filter component filters out the insoluble impurities in the wastewater, thereby completing the multi-stage treatment of the wastewater, improving the overall effect of the wastewater treatment, and improving the treatment efficiency.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
