Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum processing technology, and in particular to a rapid dehydration device for phosphogypsum processing. Background Technology

[0002] Phosphogypsum is a byproduct of phosphoric acid production in phosphate plants. Its main component is calcium sulfate dihydrate, which is acidic and contains impurities such as phosphoric acid and fluorine. Generally, 5 tons of phosphogypsum are produced for every 1 ton of phosphoric acid produced. Currently, phosphogypsum is treated by aging, neutralization reaction between lime water and gypsum slurry, etc. Dehydration treatment is required during the processing of phosphogypsum.

[0003] The existing Chinese patent, CN214811770U, discloses a centrifugal dewatering device for phosphogypsum. However, this prior art has the following drawbacks: Although the device includes a traction device that can deform the filter cloth, thereby separating the residual filter cake and improving the filtration efficiency and lifespan of the filter cloth, it relies solely on centrifugal force for dewatering and lacks auxiliary drying methods (such as airflow drying). This results in insufficient dewatering efficiency, and the moisture content of the dewatered material may not meet process requirements. Furthermore, because the dewatering process depends entirely on centrifugal force, the dewatering time is long, which not only affects processing efficiency but may also increase the load on subsequent processing steps due to high residual moisture content.

[0019] Please see Figure 1-4A rapid dehydration device for phosphogypsum processing includes a housing 1. A motor 6 is fixedly installed at the middle of the bottom surface of the housing 1, and the output end of the motor 6 is fixedly connected to a centrifugal disc 15 through the bottom surface of the housing 1. A filter frame 5 is provided above the centrifugal disc 15, and positioning blocks 16 are fixedly connected to both sides of the bottom surface of the filter frame 5. One end of the positioning block 16 extends into the interior of positioning grooves 17 opened on both sides of the top surface of the centrifugal disc 15. Electric push rods 4 are fixedly installed on both sides of the housing 1, and the output ends of the electric push rods 4 are fixedly connected to a top cover 2. A fan 12 is fixedly installed on one side of the top surface of the top cover 2, and a heating box 10 is fixedly installed on one side of the fan 12. An electric heating wire 11 is fixedly installed on one side of the interior of the heating box 10. The fan 12 is connected to the heating box 10 through an air supply pipe, and the heating box 10 is connected to an air outlet 9 installed on the bottom surface of the top cover 2 through a connecting pipe. The process involves moving the top cover 2 above the chamber 1, adding the phosphogypsum to be processed into the filter frame 5, and then moving the top cover 2 again above the chamber 1 until the air outlet 9 is positioned inside the chamber 1. The motor 6 on the bottom surface of the chamber 1 is then activated, causing the centrifugal disc 15 to rotate. The positioning groove 17 and positioning block 16 further rotate the filter frame 5, allowing for centrifugal dehydration of the material within the filter frame 5. Simultaneously, a fan 12 on one side of the top surface of the top cover 2 is activated, delivering air to the heating chamber 10. The heating wire 11 in the heating chamber 10 heats the air, which is then delivered to the air outlet 9. This hot air dries the material in the filter frame 5, allowing for simultaneous centrifugal dehydration and air-blowing dehydration, thus improving the dehydration speed.

[0020] Please see Figure 1 and Figure 4 Electromagnets 8 are fixedly installed on both sides of the bottom surface of the top cover 2 away from the air outlet 9. Iron columns 3 are fixedly welded to both sides of the top surface of the filter frame 5. The electromagnets 8 are located directly above the iron columns 3 and are matched with the iron columns 3. When the electromagnets 8 on both sides of the bottom of the top cover 2 are opened and energized, they attract the iron columns 3 at the corresponding positions on the top of the filter frame 5, forming a stable connection. Then, the electric push rod 4 is driven to move the top cover 2 vertically upward, simultaneously lifting the filter frame 5 to the outside of the box 1, so that the dehydrated phosphogypsum is fully exposed to the working area. Through the synergistic effect of electromagnetic adsorption and mechanical lifting, the rapid loading and unloading of materials is realized, effectively optimizing the operation process.

[0021] Please see Figure 1 and Figure 4 The filter frame 5 and the box 1 are circular structures. The diameter of the filter frame 5 is smaller than the diameter of the box 1. The filter frame 5 is matched with the box 1 and can maintain the normal rotation of the filter frame 5 in the box 1, so that the material can be centrifuged and dehydrated.

[0022] Please see Figure 1 , Figure 2 and Figure 4 The positioning block 16 and the positioning groove 17 are rectangular structures. The area of ​​the positioning block 16 is smaller than the area of ​​the positioning groove 17. The positioning block 16 and the positioning groove 17 are inserted into each other. By using the positioning block 16 and the positioning groove 17, the filter frame 5 can be limited on the centrifugal disc 15, so that the filter frame 5 can rotate centrifugally in the box 1, thereby centrifuging and dewatering the material.

[0023] Please see Figure 1 and Figure 3 Support legs 7 are fixedly connected to both sides of the bottom surface of the box 1. There are multiple support legs 7, and the multiple support legs 7 are evenly distributed in pairs on both sides of the bottom surface of the box 1. The support legs 7 support the box 1 and maintain the stability of the box 1 during operation.

[0024] Please see Figure 1 and Figure 3 The top cover 2 matches the box body 1, and there is a gap between the top cover 2 and the box body 1 to maintain normal air circulation, so that the material in the filter frame 5 can be dried.

[0025] Please see Figure 1 and Figure 3 A drain pipe 14 is fixedly connected to one side surface of the box 1, and a valve 13 is fixedly installed on the drain pipe 14. By opening the valve 13 on the drain pipe 14, the dehydrated water in the box 1 can be discharged to prevent it from remaining in the box 1, thus ensuring its normal use in the future.

[0026] Please see Figure 1 A sealing sleeve is installed between the output end of motor 6 and housing 1 to maintain a seal between the output end of motor 6 and housing 1 and prevent leakage.

[0027] The control switch control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. Since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0028] Working principle: In use, move the top cover 2 above the chamber 1, add the phosphogypsum to be processed into the filter frame 5, and then move the top cover 2 above the chamber 1 until the air outlet 9 is inside the chamber 1. Start the motor 6 on the bottom surface of the chamber 1. The motor 6 drives the centrifugal disc 15 to rotate. Using the positioning groove 17 and positioning block 16, the filter frame 5 can be rotated, thus centrifuging and dehydrating the material in the filter frame 5. Simultaneously, start the fan 12 on one side of the top surface of the top cover 2. The fan 12 delivers air to the heating chamber 10. The heating wire 11 in the heating chamber 10 heats the air, and the heated air is then delivered to the air outlet 9. Hot air is blown out through the air outlet 9 to dry the material in the filter frame 5. This allows for simultaneous centrifugal dehydration and air-blowing dehydration, which improves the dehydration speed and enables rapid dehydration. After dehydration, the electromagnets 8 on both sides of the bottom of the top cover 2 are opened. When energized, they attract the iron pillars 3 at the corresponding positions on the top of the filter frame 5, forming a stable connection. Then, the electric push rod 4 is driven to move the top cover 2 vertically upward, simultaneously lifting the filter frame 5 outside the box 1, so that the dehydrated phosphogypsum is fully exposed to the working area. Through the synergistic effect of electromagnetic adsorption and mechanical lifting, rapid loading and unloading of materials is achieved, effectively optimizing the operation process and improving the convenience and efficiency of equipment use.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
