Description

Technical Field

[0001] The utility model belongs to the technical field of removing organic matter from phosphogypsum, and in particular relates to equipment for removing heavy metals and fluorides in phosphogypsum. Background Art

[0002] During the processing of phosphogypsum, phosphogypsum often contains harmful substances such as heavy metals and fluorides. If these substances are discharged or used directly without effective treatment, they can have serious impacts on the environment and human health. Traditional phosphogypsum treatment methods often suffer from low treatment efficiency, high energy consumption, and unstable treatment results, making them difficult to meet modern environmental protection and sustainable development requirements.

[0003] As an effective chemical treatment method, electrolysis shows promising application prospects for removing heavy metals and fluorides from phosphogypsum. However, traditional electrolysis devices generally use a static treatment process. Due to poor fluidity, this often results in low electrolysis efficiency, difficulty separating electrolysis products, and easy precipitation during the electrolysis process, which affects treatment effectiveness and production efficiency.

[0004] Therefore, it is very necessary to invent a device for removing heavy metals and fluorides inside phosphogypsum. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a device for removing heavy metals and fluorides inside phosphogypsum, including a removal electrolytic cell, a guide baffle, an electrode rod, an electrode plate, a bubble disturber and a spiral propulsion head. The guide baffle is fixedly installed in the middle of the removal electrolytic cell, and several electrode rods are fixedly installed on the removal electrolytic cell and the guide baffle, and an electrode plate is fixedly installed under each of the electrode rods; several of the electrode plates are located above the bubble generating box of the bubble disturber, and the bubble generating box is fixedly installed on the bottom of the removal electrolytic cell. A spiral propulsion head is provided on one side of the bubble disturber.

[0006] Preferably, the spiral propulsion head is mounted on the removal electrolytic cell via a sealed bearing sleeve, and the spiral propulsion head is fixed to an output end of a driving component fixedly mounted outside the removal electrolytic cell.

[0007] Preferably, the spiral propulsion head is located on one side of one end of the guide baffle and at the bottom of one end of the removal electrolytic cell, and the guide baffle is used to separate the removal electrolytic cell into a complete closed-loop circulation space.

[0008] Preferably, the electrode rods are divided into positive electrode rods and negative electrode rods, the electrode plate installed on the positive electrode rod is the positive electrode plate, and the electrode plate installed on the negative electrode rod is the negative electrode plate. The electrode rods are connected to a high-frequency generator fixedly installed outside the electrolytic cell.

[0009] Preferably, channels for the flow of phosphogypsum are formed between the electrode plates, and the positive electrode plate and the negative electrode plate are arranged on one side of each other.

[0010] Preferably, the bubble disturber also includes a fine hole, a connecting pipe, a high-pressure tank, a one-way valve and a high-pressure air pump. The fine hole is arranged on the upper surface of the bubble generating box. The bubble generating box is connected to the high-pressure tank by passing through a connecting pipe that removes the electrolytic cell. A one-way valve is installed on the connecting pipe; the high-pressure air pump is fixedly installed on the high-pressure tank.

[0011] Preferably, the high-pressure air pump is used to inject the generated high-pressure gas into the high-pressure tank, and the high-pressure gas is stored in the high-pressure tank. The high-pressure tank, the one-way valve and the high-pressure air pump are arranged outside the electrolytic cell.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model combines precisely configured flow guide baffles, spiral propulsion heads, and efficient bubble disturbers. This solution significantly improves the overall efficiency and effect of the phosphogypsum electrolysis process. The unique electrolytic cell layout not only realizes the continuous and circular flow of phosphogypsum in the cell, but also greatly prolongs its contact time with the electrode plates and expands the contact area, thereby directly promoting the depth and rate of the electrolysis reaction and improving the electrolysis efficiency. At the same time, the carefully planned alternating arrangement strategy of the phosphogypsum flow channel and the positive and negative plates effectively promotes the immediate separation and collection of the electrolysis products, avoids the product mixing and precipitation problems in traditional methods, and significantly optimizes the purity and collection efficiency of the electrolysis products. In addition, the large number of tiny bubbles generated by the built-in bubble disturber during the electrolysis process have a strong disturbing effect on the phosphogypsum particles, which not only enhances its suspension and fluidity, but also further promotes the uniform distribution of the electrolyte and the full contact with the reactants. The synergistic effect of multiple aspects greatly improves the electrolysis efficiency and treatment effect, and opens up a new path for the efficient and clean production of the phosphogypsum electrolysis process.

[0021] As attached Figure 1 To the attached Figure 3 As shown:

[0022] The utility model provides a device for removing heavy metals and fluorides inside phosphogypsum, comprising a removal electrolytic cell 1, a guide baffle 2, an electrode rod 3, an electrode plate 4, a bubble disturber 5 and a spiral propulsion head 6. The guide baffle 2 is fixedly installed in the middle of the removal electrolytic cell 1, and a plurality of the electrode rods 3 are fixedly installed on the removal electrolytic cell 1 and the guide baffle 2. An electrode plate 4 is fixedly installed below each of the electrode rods 3; the plurality of electrode plates 4 are located above a bubble generating box 51 of the bubble disturber 5, and the bubble generating box 51 is fixedly installed on the bottom of the removal electrolytic cell 1. A spiral propulsion head 6 is provided on one side of the bubble disturber 5.

[0023] Furthermore, the screw propeller 6 is precisely mounted on the electrolytic cell 1 via a sealed bearing sleeve, ensuring its stability and sealing during operation. The screw propeller 6 is closely connected to the output end of a drive component 7 mounted outside the electrolytic cell 1. Powered by the drive component 7, the screw propeller 6 rotates within the cell, pushing the phosphogypsum particles along a specific path.

[0024] Furthermore, the spiral propeller 6 is strategically positioned on one side of the flow-guiding baffle 2 and at the bottom of one end of the electrolytic cell 1. The flow-guiding baffle 2, a key component, separates the electrolytic cell 1 into a complete closed-loop circulation space. This design allows the phosphogypsum, propelled by the spiral propeller, to circulate continuously along the path formed by the flow-guiding baffle, thereby ensuring a continuous and efficient electrolysis process.

[0025] Furthermore, the electrode rods 3 are clearly divided into positive and negative electrode rods, which respectively carry positive and negative electrode plates 4. These electrode plates 4 are connected to a high-frequency generator 8 fixedly mounted outside the electrolytic cell 1 via their respective electrode rods 3. The high-frequency generator 8 provides the necessary electrical energy for the electrolysis process, ensuring the smooth progress of the electrolysis reaction.

[0026] Furthermore, carefully designed channels for the flow of phosphogypsum are located between the electrode plates 4. These channels not only allow the free flow of phosphogypsum particles but also ensure effective spacing between the positive and negative plates during the electrolysis reaction. The positive and negative plates are arranged on either side of each other, forming an alternating pattern that helps enhance the uniformity and efficiency of the electrolysis reaction.

[0027] Furthermore, the bubble disturber 5, an important auxiliary device for improving electrolysis efficiency, includes key components such as fine holes 52, a connecting pipe 53, a high-pressure tank 54, a one-way valve 55, and a high-pressure air pump 56. The fine holes 52 are densely distributed on the upper surface of the bubble generating box 51. When high-pressure gas passes through, it can generate a large number of tiny bubbles in the electrolytic cell.

[0028] Furthermore, a high-pressure gas pump 56 is responsible for injecting the generated high-pressure gas into a high-pressure tank 54 for storage. High-pressure tank 54 is connected to bubble generating box 51 via a pipe 53. A one-way valve 55 installed on pipe 53 ensures unidirectional gas flow and prevents backflow. The entire high-pressure gas supply system is cleverly located outside of electrolytic cell 1, ensuring safe and stable operation of the system while facilitating routine maintenance and inspection.

[0029] The operating principle is as follows: First, phosphogypsum particles are placed into the removal electrolytic cell 1. At this point, the screw propeller 6 begins to rotate, driven by an external drive component 7. This rotational motion propels the phosphogypsum particles along the path formed by the guide baffles 2, creating a continuous circulation. This design ensures thorough mixing and uniform distribution of the phosphogypsum particles within the electrolytic cell, creating optimal conditions for the subsequent electrolytic reaction.

[0030] Then, high-frequency generator 8 begins operating, providing the necessary electrical energy to the positive and negative plates 4 mounted on electrode rods 3. These plates 4 create an electric field within the electrolytic cell. As phosphogypsum particles flow through these plates, the heavy metal ions and fluoride ions within them undergo an electrolytic reaction under the influence of the electric field. The positive plates attract and remove negatively charged ions (such as fluoride ions), while the negative plates attract and remove positively charged ions (such as heavy metal ions).

[0031] As the electrolysis reaction proceeds, the bubble disturber 5 also begins operating. High-pressure gas pump 56 injects the generated high-pressure gas into high-pressure tank 54 for storage and then transports it to bubble generation box 51 via connecting pipe 53. As the high-pressure gas passes through pores 52, a large number of tiny bubbles are generated in the electrolytic cell. As these bubbles rise, they continuously disturb the phosphogypsum particles, increasing their suspension and fluidity, thereby improving the efficiency and uniformity of the electrolysis reaction. Furthermore, the disturbing effect of the bubbles helps prevent the deposition and agglomeration of electrolysis products on the electrode plates, further enhancing the treatment effect.

[0032] Finally, the phosphogypsum particles, having undergone the electrolysis reaction and bubble disturbance, continue to circulate under the propulsion of the screw propeller 6. During this process, the electrolysis products (such as the removed heavy metals and fluorides) are gradually separated from the phosphogypsum and collected and processed through the flow channels between the electrode plates. The entire electrolysis process effectively removes the heavy metals and fluorides in the phosphogypsum while ensuring the continuity and efficiency of the electrolysis reaction.

[0033] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
