Description

Technical Field

[0001] This invention relates to the field of polyferric sulfate production technology, specifically to a polyferric sulfate production device with waste recycling function. Background Technology

[0002] Polyferric sulfate, as a highly efficient inorganic polymeric flocculant, began its industrialization in the 1980s with gas-liquid mixing technology. Through three generations of technological innovation—catalytic oxidation and green preparation—it has developed into a product system encompassing both liquid and solid forms. From early intermittent production to modern continuous intelligent factories, core technological breakthroughs have focused on three main areas: improving reaction efficiency, controlling product stability, and optimizing environmental performance.

[0003] Polyferric sulfate is an inorganic polymeric flocculant widely used in water treatment. Its finished product form directly affects the flocculation effect and storage and transportation performance. Currently, the core process for the industrial preparation of solid polyferric sulfate is solution atomization-heat curing. Most mainstream equipment adopts "static drying" or "simple rotary drying" modes, which have the drawbacks of low curing efficiency and serious raw material waste.

[0004] In existing polyferric sulfate production processes, the liquid finished product is dried into a solid state using a drying device, which facilitates the storage and transportation of polyferric sulfate. However, the existing drying equipment uses static drying and fixed air supply, which does not allow for sufficient contact with dynamic materials and is not suitable for uniform drying of polyferric sulfate. This can easily affect the production quality and efficiency of polyferric sulfate. Summary of the Invention

[0016] The beneficial effects of this invention are: (1) The drive motor is turned, which drives the first drive gear to rotate, which in turn drives the second drive gear to rotate, which in turn drives the placement frame to rotate. This is used to evenly turn the polyferric sulfate, which is convenient for even drying of the polyferric sulfate. At the same time, the transmission sprocket drives the transmission chain to rotate, which causes the reciprocating screw to rotate and drives the moving block to move. At the same time, the fan and heating tube are turned, which causes the drying hot air to be blown out through the horn tube and enters the placement frame to reciprocate and evenly dry the polyferric sulfate. The rotating placement frame further improves the even drying of the polyferric sulfate, which is used to evenly dry the polyferric sulfate, and improves the processing quality and efficiency of the polyferric sulfate.

[0017] (2) When the placement frame rotates, it drives the gear ring to rotate, which in turn drives the first rotating gear to rotate, which in turn drives the second rotating gear to rotate, which in turn drives the first and second stirring rods to rotate, which in turn drives the stirring blades to rotate, thus stirring the polyferric sulfate and reducing the agglomeration of the polyferric sulfate. Combined with the drying of the trumpet tube, this further improves the uniform drying effect of the polyferric sulfate. At the same time, the first rotating gear drives the connecting plate to rotate and move, which performs planetary stirring of the polyferric sulfate, further improving the stirring effect and facilitating the uniform drying of the material. At the same time, the connecting plate rotates, which causes the electric telescopic rod to rotate, which causes the scraper to scrape and clean the inner wall of the placement frame, reducing the situation of polyferric sulfate adhering to the inner wall of the placement bucket and facilitating the uniform drying of the material.

[0018] (3) When the placement frame rotates, the droplets flowing out of the placement frame are guided by the connecting box, and the filter plate filters the droplets so that the solids remain on the filter plate, which is convenient for the recovery and filtration of the liquid during drying.

At the same time, the cleaning motor is run so that the cleaning screw rotates, which drives the cleaning plate to move, which causes the cleaning brush and scraper to move. The spring force resists the spring force, which causes the cleaning brush and scraper to be stressed, which improves the cleaning effect on the filter plate, reduces the clogging of the filter plate, and drives the solids into the collection container, which is convenient for the recovery of the material. At the same time, the cam rotates so that the filter plate vibrates, which reduces the clogging of the filter plate and facilitates the recovery and reuse of the material.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 Based on Example 1, please refer to Figures 1-3 As shown, the present invention is a polyferric sulfate production device with waste recycling function, including a frame 1, two symmetrical heating blocks fixed inside the frame 1, a placement frame 2 installed inside the frame 1, and trapezoidal drying holes arranged in an array on the placement frame 2 for processing polyferric sulfate. An installation tank 3 and a water pump 8 are provided at one end of the frame 1. The water pump 8 sprays material into the placement frame 2 through a nozzle. A fixing sleeve 10 is fixed at one end of the placement frame 2. The frame 1 is equipped with a reciprocating screw 12 assembly and a rotating assembly. The reciprocating screw 12 assembly includes a fixed frame 4 fixed to the lower end of the frame 1, a drive motor 5 fixed on the fixed frame 4, the output end of the drive motor 5 extending into the fixed frame 4 and rotatably connected to the frame 1. A fixed box 19 is fixed on one side of the frame 1, the reciprocating screw 12 is installed inside the fixed box 19, a horn tube 16 is installed on the reciprocating screw 12, and an array of heating tubes is fixed inside the horn tube 16, driving the horn tube 16 and the heating tubes to move back and forth for reciprocating scanning drying of materials. A gear set is installed at the output end of the drive motor 5 for rotating the placement frame 2. The rotating assembly includes a cover plate 21 fixed to one end of the frame 1, a vacuum pump 20 for collecting solidified materials under negative pressure is installed on the cover plate 21, the cover plate 21 is rotatably connected to the placement frame 2, and a stirring rod 1 25 and a stirring rod 26 are installed on the cover plate 21. A scraper 30 is installed on the stirring rod 1 25 for planetary stirring of materials. The reciprocating screw 12 assembly includes a drive gear 6 fixed to the output end of the drive motor 5, and a drive gear 7 fixed to the fixed sleeve 10. The drive gear 6 and drive gear 7 mesh with each other. Both the fixed sleeve 10 and the end of the reciprocating screw 12 are fixed with transmission sprockets, which are connected by a transmission chain 9. One end of the reciprocating screw 12 extends out of the fixed box 19. A moving block 13 is fixed to the reciprocating screw 12 by a ball nut. A fan 14 is fixed to the fixed box 19. A ventilation pipe is fixed to the end of the fan 14. A telescopic pipe 15 is fixed to the end of the fan 14 away from the ventilation pipe. The telescopic pipe 15 extends into the fixed box 19 and is fixedly connected to a horn pipe 16. The moving block 13 is fixedly connected to the horn pipe 16. A protective shell 17 is fixed inside the fixed box 19. A limiting groove 18 is provided on the protective shell 17. The reciprocating screw 12 is located in the limiting groove 18. The moving block 13 is slidably disposed with respect to the protective shell 17.

[0024] Specifically, the workers add the polyferric sulfate to be dried into the installation tank 3, and use water pump 8 to draw out the liquid polyferric sulfate, which is then sprayed out through a nozzle. The nozzle is an atomizing nozzle, so that the atomized material enters the placement frame 2. At the same time, the heating block is operated, so that heated air is passed through the drying holes on the placement frame 2 to dry the polyferric sulfate. The reciprocating screw 12 assembly drives the horn tube 16 to move back and forth, performing a reciprocating scanning drying of the polyferric sulfate, which is used for uniform drying of the polyferric sulfate. In conjunction with the rotating placement frame 2, the drying effect of polyferric sulfate is further improved, thereby improving the processing quality and efficiency of polyferric sulfate.

[0025] Specifically, the drive motor 5 is operated, causing the drive gear 6 to rotate, which in turn drives the drive gear 7 to rotate, causing the fixed sleeve 10 to rotate the placement frame 2. This is used to evenly turn the polyferric sulfate, facilitating uniform drying. At the same time, the transmission sprocket drives the transmission chain 9 to rotate, causing the reciprocating screw 12 to rotate, which in turn causes the ball nut to move the moving block 13. The moving block 13 moves within the protective shell 17, which restricts its movement. Simultaneously, the fan 14 and heating tube are operated, allowing air to enter the fan 14 through the ventilation pipe. The filter screen in the ventilation pipe filters the air, reducing dust and debris entering the placement frame 2. The drying hot air is blown out through the horn tube 16 and enters the placement frame 2, reciprocating and evenly drying the polyferric sulfate. The telescopic tube 15 extends and retracts, and the drying hole is trapezoidal, facilitating the entry of drying hot air. This, combined with the rotating placement frame 2, further improves the uniform drying of the polyferric sulfate.

[0026] Example 2 Based on Example 1, please refer to Figures 3-5 As shown, the rotating assembly also includes a gear ring 22 fixed within the placement frame 2. The cover plate 21 is rotatably connected to the first stirring rod 25 and the second stirring rod 26. A rotating gear 23 is fixed to the end of the first stirring rod 25, and a rotating gear 24 is fixed to the end of the second stirring rod 26. The first rotating gear 23 meshes with the second rotating gear 24. The gear ring 22 meshes with the first rotating gear 23. An array of stirring blades 31 is fixed to both the first stirring rod 25 and the second stirring rod 26. The first stirring rod 25 and the second stirring rod 26 are rotatably connected via a rotating plate. A connecting plate 27 is fixed to the end of the second stirring rod 26, and an electric telescopic rod 28 is fixed to the connecting plate 27. A support plate 29 is fixed to the telescopic end of the electric telescopic rod 28. Both the support plate 29 and the connecting plate 27 are fixedly connected to the scraper 30. The stirring blades 31 on stirring rod 25 and stirring rod 26 are staggered. The stirring blades 31 have arrayed turbulence holes. All three stirring rods (25, 26, and 31) are made of alloy metal and have an anti-fouling coating. A water outlet pipe is fixed to the outlet end of water pump 8 and is fixedly connected to the spray nozzle. A sealing ring is installed inside the fixing sleeve 10 and the water outlet pipe. A spray tower 11 is fixedly connected to the frame 1 via a collection pipe for treating exhaust gas during drying.

[0027] Specifically, when the placement frame 2 rotates, it drives the gear ring 22 to rotate, causing the rotating gear 23 to rotate, which in turn drives the rotating gear 24 to rotate, causing the stirring rods 25 and 26 to rotate, and the stirring blades 31 to rotate, thus stirring the polyferric sulfate and reducing its agglomeration. Combined with the drying function of the bell tube 16, this further improves the uniform drying effect of the polyferric sulfate. Simultaneously, the rotating gear 23 drives the connecting plate 27 to rotate and move, causing the stirring rod 25 to rotate and move, performing planetary stirring of the polyferric sulfate. The rotating plate restricts the stirring rod 25, further improving the stirring effect and facilitating uniform drying of the material. The stirring blades 31 on the stirring rods 25 and 26 rotate in a crisscross pattern, improving the stirring effect of the material and reducing agglomeration. To improve the drying effect, the stirring rods 25 and 26, and the stirring blades 31 are all made of titanium-aluminum alloy with laser cladding high-temperature resistant coating, reducing material contamination. The turbulence holes on the stirring blades 31 enhance the drying effect on the material. At the same time, the connecting plate 27 rotates, causing the electric telescopic rod 28 to rotate, which allows the scraper 30 to scrape and clean the inner wall of the placement frame 2, reducing the amount of polyferric sulfate contaminating the inner wall of the placement tank and facilitating uniform drying of the material. Simultaneously, the operation of the electric telescopic rod 28 controls the distance between the scraper 30 and the inner wall of the placement frame 2, facilitating material scraping and reducing wear on the scraper 30. The water pump 8 provides power for the spraying of the nozzles, and the water outlet pipe facilitates the entry of material into the nozzles. The collection pipe and spray tower 11 facilitate the treatment and discharge of drying exhaust gas.

[0028] Example 3 Based on Example 2, please refer to Figure 3 , Figure 6 , Figure 7As shown, a connecting box 32 is fixed to the lower end of the frame 1. The connecting box 32 is trumpet-shaped and contains a filter plate 39. A cleaning motor 35 is fixed to one end of the connecting box 32. The output end of the cleaning motor 35 extends into the connecting box 32 and is fixedly connected to a cleaning screw 36. A sliding block 37 is fixed to the cleaning screw 36 by a ball nut. A limiting box 43 is fixed inside the connecting box 32. The limiting box 43 and the sliding block 37 are slidably disposed. A fixing plate 38 is fixed to the lower end of the sliding block 37. A cleaning plate 40 is provided at the lower end of the filter plate 38. A cleaning brush 41 is fixed on the cleaning plate 40. A scraper 42 is fixed on one side of the cleaning plate 40. Both the cleaning brush 41 and the scraper 42 slide in contact with the filter plate 39. A collection box 33 is fixed at the lower end of the connecting box 32. A second water pump 34 is provided on one side of the collection box 33. The outlet of the second water pump 34 is fixedly connected to the installation tank 3 via a connecting pipe. A collection container 48 is provided at one end of the connecting box 32. The collection container 48 extends into the connecting box 32 and corresponds to the filter plate 39. Two symmetrical sliding columns 50 are slidably arranged on the fixed plate 38. A limiting block is fixed at the upper end of the sliding column 50. A resisting spring 47 is sleeved on the sliding column 50. The ends of the resisting spring 47 are fixedly connected to the limiting block and the fixed plate 38. The sliding column 50 passes through the fixed plate 38 and is fixedly connected to the cleaning plate 40. Two symmetrical telescopic columns 46 are fixed inside the connecting box 32. Vibration springs 49 are fitted on the telescopic columns 46. The telescopic ends of the telescopic columns 46 are fixedly connected to the filter plate 39. The upper end of the vibration springs 49 is fixedly connected to the filter plate 39. A roller is rotatably connected to one end of the filter plate 39. A cam 45 is provided at the lower end of the roller. A rotating sprocket is fixed to one end of the cam 45 extending out of the connecting box 32. A rotating sprocket is fixed to the output end of the cleaning motor 35. The two rotating sprockets are connected by a connecting chain 44.

[0029] Specifically, when the placement frame 2 rotates, the droplets flowing out of the placement frame 2 are guided by the connecting box 32, and the filter plate 39 filters the droplets, leaving solids on the filter plate 39 for easy liquid recovery during drying. The liquid then enters the recovery box 33 for easy recovery. The water pump 34 is then activated, allowing the liquid to enter the installation tank 3 through the connecting pipe for further filtration and recovery. Simultaneously, the cleaning motor 35 is activated, causing the cleaning screw 36 to rotate. This causes the ball nut to move the sliding block 37, which slides within the limiting box 43, restricting the fixed plate 38. This movement of the fixed plate 38 then moves the cleaning plate 40, causing the cleaning brush 41 to move. As the scraper 42 moves, the elastic force of the spring 47 causes the sliding column 50 to be stressed. The sliding column 50 slides on the fixed plate 38, causing the cleaning brush 41 and the scraper 42 to be stressed, further improving the cleaning effect on the filter plate 39, cleaning the solid material on the filter plate 39, reducing the clogging of the filter plate 39, and driving the solid into the collection container 48 for easy material recycling. At the same time, the rotating sprocket drives the connecting chain 44 to rotate, causing the cam 45 to rotate, causing the roller to move and rotate, causing the filter plate 39 to vibrate, driving the telescopic column 46 to extend and retract, causing the vibration spring 49 to extend and retract, improving the vibration effect of the filter plate 39, reducing the clogging of the filter plate 39, and facilitating the recycling and reuse of materials.

[0030] The working principle of this invention is as follows: The operator adds the polyferric sulfate that needs to be dried into the installation tank 3, and the water pump 8 draws out the polyferric sulfate liquid and sprays it out through the nozzle. The nozzle is an atomizing nozzle, so that the atomized material enters the placement frame 2. At the same time, the heating block is operated so that the heated air dries the polyferric sulfate through the drying hole on the placement frame 2. Then, the drive motor 5 is operated, causing the drive gear 6 to rotate, which in turn drives the drive gear 7 to rotate, causing the fixed sleeve 10 to rotate the placement frame 2. This is used to evenly turn the polyferric sulfate, facilitating its uniform drying. Simultaneously, the transmission sprocket drives the transmission chain 9 to rotate, causing the reciprocating screw 12 to rotate. This causes the ball nut to move the moving block 13, restricting its movement within the protective shell 17. At the same time, the fan 14 and heating element are operated, allowing air to enter the fan 14 through the ventilation duct. The filter screen inside the ventilation duct filters the air, reducing dust and debris. The waste enters the placement frame 2, allowing hot drying air to be blown out through the horn pipe 16. This hot air then enters the placement frame 2, reciprocating to evenly dry the polyferric sulfate. The telescopic tube 15 extends and retracts, and the trapezoidal drying hole facilitates the entry of hot drying air. The rotating placement frame 2 further enhances the uniform drying of the polyferric sulfate. As the placement frame 2 rotates, it drives the gear ring 22 to rotate, causing the first rotating gear 23 to rotate, which in turn drives the second rotating gear 24. This causes the first stirring rod 25 and the second stirring rod 26 to rotate, resulting in the rotation of the stirring blade 31, which stirs the polyferric sulfate and reduces agglomeration. The drying of the bell-shaped tube 16 further improves the uniform drying effect of polyferric sulfate. Simultaneously, the rotating gear 23 drives the connecting plate 27 to rotate, which in turn drives the stirring rod 25 to rotate, performing planetary stirring of the polyferric sulfate and further improving the stirring effect, facilitating uniform drying of the material. The stirring blades 31 on the stirring rod 25 and stirring rod 26 rotate crosswise, improving the stirring effect of the material, reducing agglomeration, and improving the drying effect. Since the stirring rods 25 and 26, and the stirring blades 31 are all made of titanium-aluminum based alloy with laser cladding high-temperature resistant coating, material contamination is reduced. The turbulence holes on the stirring blade 31 improve the drying effect on the material. At the same time, they drive the connecting plate 27 to rotate, causing the electric telescopic rod 28 to rotate. This allows the scraper 30 to scrape and clean the inner wall of the placement frame 2, reducing the amount of polyferric sulfate adhering to the inner wall of the placement tank and facilitating uniform drying of the material. Simultaneously, the operation of the electric telescopic rod 28 controls the distance between the scraper 30 and the inner wall of the placement frame 2, facilitating the scraping of the material and reducing the wear of the scraper 30. The water pump 8 provides power for the spraying of the nozzles, and the water outlet pipe facilitates the entry of the material into the nozzles. The collection pipe and spray tower 11 facilitate the treatment and discharge of the drying exhaust gas. Then, as the placement frame 2 rotates, the droplets flowing out of the placement frame 2 are guided by the connecting box 32, and the filter plate 39 filters the droplets, leaving solids on the filter plate 39 for easy liquid recovery during drying. The liquid then enters the recovery box 33 for easy recovery. Next, the water pump 34 is operated, allowing the liquid to enter the installation tank 3 through the connecting pipe for easy filtration and recovery. Simultaneously, the cleaning motor 35 is operated, causing the cleaning screw 36 to rotate, which in turn causes the ball nut to move the sliding block 37. The sliding block 37 slides within the limiting box 43, restricting the fixed plate 38. This movement of the fixed plate 38 then moves the cleaning plate 40, causing the cleaning brush 41 and... The scraper 42 moves, and the elastic force of the spring 47 causes the sliding column 50 to be stressed. The sliding column 50 slides on the fixed plate 38, which causes the cleaning brush 41 and the scraper 42 to be stressed, further improving the cleaning effect on the filter plate 39, cleaning the solid material on the filter plate 39, reducing the blockage of the filter plate 39, and driving the solid material into the collection container 48. After collection, the solid material is taken out for further processing and recycling, which facilitates the recycling of materials. At the same time, the rotating sprocket drives the connecting chain 44 to rotate, which causes the cam 45 to rotate, which causes the roller to move and rotate, causing the filter plate 39 to vibrate, driving the telescopic column 46 to extend and retract, which causes the vibration spring 49 to extend and retract, improving the vibration effect of the filter plate 39.

[0031] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
