Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please see Figure 1-4 The present invention provides the following technical solution: a multi-stage purification and washing device for the production of low-impurity ferric phosphate, including a washing tank 1, a number of partitions 4 fixed inside the washing tank 1, support legs 5 on both sides of the lower end of the washing tank 1, shock-absorbing components 3 at the lower end of the support legs 5, and a washing component 2 inside the washing tank 1. The washing assembly 2 includes a support frame 22. The support frame 22 is fixed to the upper side of both ends of the washing tank 1. A folding plate 21 is fixed to the other end of the support frame 22. A motor 24 is installed at one end of the folding plate 21. A screw 25 is provided at the output end of the motor 24. A movable seat 26 is threadedly connected to the surface of the screw 25. Electric push rods 27 are installed on both sides of the lower end of the movable seat 26. A washing drum 23 is provided at the output end of the electric push rod 27. Several through holes are opened in the washing drum 23 for the washing liquid to enter. A feed hopper 28 is provided at the middle position of the upper end of the washing drum 23.

[0017] Specifically, the washing assembly 2 also includes a discharge port 210. The lower end of the washing drum 23 has a discharge port 210. A sealing plate 211 is bolted to the lower end of the washing drum 23 at the position corresponding to the discharge port 210. An agitator 29 is installed inside the washing drum 23.

[0018] By adopting the above technical solution, the ferric phosphate to be cleaned is added to the washing drum 23 through the feed hopper 28. The electric push rod 27 is turned on to push the washing drum 23 into the cleaning chamber on one side of the washing tank 1 for cleaning. After cleaning, the electric push rod 27 is turned on to retract and drive the washing drum 23 to move upward. The motor 24 is turned on to drive the screw 25 to rotate and drive the moving seat 26 to move. The moving seat 26 moves the washing drum 23 to the top of another cleaning chamber. The electric push rod 27 is turned on to push the washing drum 23 into the cleaning chamber for cleaning. The above steps are repeated so that the washing drum 23 enters the next level cleaning chamber for cleaning. After the ferric phosphate in the washing drum 23 has undergone multi-stage cleaning, the bolts fixing the sealing plate 211 are removed, and the ferric phosphate in the washing drum 23 can be discharged from the washing drum 23 through the discharge port 210. The washing assembly 2 is set up to facilitate the transfer of ferric phosphate, thereby facilitating multi-stage washing of ferric phosphate.

[0019] Specifically, the stirring assembly 29 includes a second motor 291. The second motor 291 is installed at the front end of the washing drum 23. A protective cover 292 is fixed at the front end of the washing drum 23 corresponding to the position of the second motor 291. A rotating shaft 293 is provided at the output end of the second motor 291. Several stirring rods 294 are fixed on the rotating shaft 293. Connecting rods 295 are fixed on both sides of one end of the rotating shaft 293. A scraper 296 is fixed at the other end of the connecting rod 295. The side of the scraper 296 is tangent to the inner wall of the washing drum 23.

[0020] By adopting the above technical solution, when cleaning the ferric phosphate in the washing drum 23, the motor 291 is turned on to drive the rotating shaft 293 to rotate. The rotation of the rotating shaft 293 can stir the ferric phosphate in the washing drum 23 through several stirring rods 294, thereby improving the cleaning effect of ferric phosphate. At the same time, the rotating shaft 293 drives the scraper 296 to rotate through the connecting rod 295. The scraper 296 can scrape off and clean the ferric phosphate adhering to the inner wall of the washing drum 23, avoiding the ferric phosphate from clogging the through holes on the washing drum 23 and preventing the cleaning liquid from entering the washing drum 23.

[0021] Specifically, the washing assembly 2 also includes a T-shaped block 212, the upper end of the movable seat 26 is fixed with the T-shaped block 212, and the folding plate 21 is provided with a sliding groove 213 corresponding to the T-shaped block 212.

[0022] By adopting the above technical solution, the T-shaped block 212 at the upper end of the movable seat 26 can slide in the slide groove 213 when the movable seat 26 moves, thereby making the movement of the movable seat 26 more stable.

[0023] In this embodiment, when using the multi-stage purification and washing device for low-impurity ferric phosphate production, the device is installed in a suitable position, and the cleaning solution is added to the washing tank 1. Several partitions 4 divide the interior of the washing tank 1 into several washing chambers. The ferric phosphate to be cleaned is added to the washing cylinder 23 through the feed hopper 28. The electric push rod 27 is activated to push the washing cylinder 23 into one of the washing chambers inside the washing tank 1 for cleaning. After cleaning, the electric push rod 27 is activated to retract, causing the washing cylinder 23 to move upward. The motor 24 drives the screw 25 to rotate, causing the moving seat 26 to move. The moving seat 26 moves the washing cylinder 23 to the top of another washing chamber. The electric push rod 27 is activated again to push the washing cylinder 23 into the washing chamber for cleaning. The above steps are repeated to allow the washing cylinder 23 to enter the next stage of the washing chamber for cleaning. After the ferric phosphate in the drum 23 has undergone multi-stage cleaning, the bolts fixing the sealing plate 211 are removed, and the ferric phosphate in the washing drum 23 can be discharged through the discharge port 210. The washing component 2 is set to facilitate the transfer of ferric phosphate, thereby facilitating multi-stage washing of ferric phosphate. The stirring component 29 is set to drive the rotating shaft 293 to rotate when the ferric phosphate in the washing drum 23 is being cleaned. The rotation of the rotating shaft 293 can stir the ferric phosphate in the washing drum 23 through several stirring rods 294, improving the cleaning effect of ferric phosphate. At the same time, the rotating shaft 293 drives the scraper 296 to rotate through the connecting rod 295. The scraper 296 can scrape and clean the ferric phosphate adhering to the inner wall of the washing drum 23, avoiding the ferric phosphate from clogging the through holes on the washing drum 23 and preventing the cleaning liquid from entering the washing drum 23.

[0024] Example 2: The difference between this embodiment and embodiment 1 is that the shock absorption component 3 includes a fixed frame 31. The fixed frame 31 is provided on the lower side of the washing tank 1 at the position corresponding to the support leg 5. The lower end of the support leg 5 is fixed with a sliding plate 32. The two ends of the sliding plate 32 are fixed with protruding plates 33. The fixed frame 31 has a rectangular groove 34 corresponding to the protruding plate 33 inside. The lower end of the protruding plate 33 is provided with a damping rod 35. A spring 36 is sleeved on the outside of the damping rod 35 at the lower end of the protruding plate 33.

[0025] By adopting the above technical solution, the device generates vibration during use. The vibration pushes the slide plate 32 at the lower end of the support leg 5 to slide in the fixed frame 31. The convex plates 33 at both ends of the slide plate 32 slide in the rectangular groove 34. The convex plates 33 compress the damping rod 35 and the spring 36. The damping rod 35 and the spring 36 can buffer and reduce the shock of the device. By setting the shock absorption component 3, the device can buffer and reduce the shock, thus improving the practicality of the equipment.

[0026] Specifically, the shock absorption component 3 also includes a vertical plate 37, with the lower end of the fixed frame 31 having the vertical plate 37 fixed inside, and a rubber strip 38 fixed to the upper end of the vertical plate 37.

[0027] By adopting the above technical solution, the vertical plate 37 fixed at the lower end inside the fixed frame 31 can limit the sliding plate 32, preventing the sliding plate 32 from shaking too much and causing damage to the damping rod 35. At the same time, the rubber strip 38 set at the upper end of the vertical plate 37 can buffer the sliding plate 32 when it contacts the vertical plate 37.

[0028] Specifically, the upper end of the fixed frame 31 has sliding holes on both sides corresponding to the support legs 5, and the side of the sliding plate 32 is in contact with the inner wall of the fixed frame 31.

[0029] By adopting the above technical solution, the support leg 5 can slide on the upper end of the fixed frame 31, and the side of the slide plate 32 fits against the inner wall of the fixed frame 31, making the slide plate 32 move more stably in the fixed frame 31.

[0030] In this embodiment, the device vibrates during use, which pushes the slide plate 32 at the lower end of the support leg 5 to slide in the fixed frame 31. The convex plates 33 at both ends of the slide plate 32 slide in the rectangular groove 34. The convex plates 33 compress the damping rod 35 and the spring 36. The damping rod 35 and the spring 36 can buffer and reduce the shock of the device. By setting the shock absorption component 3, the device can buffer and reduce the shock, improving the practicality of the equipment. By fixing the vertical plate 37 at the lower end inside the fixed frame 31, the slide plate 32 can be limited, preventing the slide plate 32 from shaking too much and causing damage to the damping rod 35. At the same time, the rubber strip 38 set at the upper end of the vertical plate 37 can buffer the contact between the slide plate 32 and the vertical plate 37.

[0032] In this utility model, the motor 291 is a previously disclosed technology, and the selected model is Z60-55ZY.

[0033] In this utility model, the electric push rod 27 is a previously disclosed technology, and the selected model is FTG50.

[0034] The damping rod 35 in this utility model is a previously disclosed technology, and the selected model is SQS.

[0035] The structure and working principle of the washing tank 1, partition 4 and support leg 5 in this utility model have been disclosed in a belt washing machine for iron phosphate production disclosed in Chinese Patent Publication No. CN118479438A.

[0036] The working principle and usage process of this utility model: When using the multi-stage purification and washing device for low-impurity ferric phosphate production, the device is installed in a suitable position, and the washing solution is added to the washing tank 1. Several partitions 4 divide the interior of the washing tank 1 into several washing chambers, thereby adding the corresponding washing solution to each of the several washing chambers. The partitions 4 prevent different washing solutions from mixing. The ferric phosphate to be washed is added to the washing cylinder 23 through the feed hopper 28. The electric push rod 27 is turned on to push the washing cylinder 23 into one of the washing chambers inside the washing tank 1 for washing. After washing is completed, the electric push rod 27 retracts, causing the washing cylinder 23 to rise. Then, the motor 24 drives the screw 25 to rotate, which in turn moves the moving seat 26. This movement of the moving seat 26 moves the washing drum 23 above another cleaning chamber. The electric push rod 27 is then activated again to push the washing drum 23 into the cleaning chamber for further cleaning. This process is repeated to move the washing drum 23 into the next cleaning chamber for further cleaning. After the ferric phosphate in the washing drum 23 has undergone multiple cleaning stages, the bolts fixing the sealing plate 211 are removed. The ferric phosphate in the washing drum 23 can then be discharged through the outlet 210. The washing assembly 2 facilitates the transfer of ferric phosphate, thus improving the cleaning process. The ferric phosphate undergoes multi-stage washing. A stirring assembly 29 is installed. When cleaning the ferric phosphate in the washing drum 23, motor 291 drives the rotating shaft 293 to rotate. The rotation of the rotating shaft 293 stirs the ferric phosphate in the washing drum 23 through several stirring rods 294, improving the cleaning effect. Simultaneously, the rotating shaft 293 drives the scraper 296 to rotate via the connecting rod 295. The scraper 296 scrapes away the ferric phosphate adhering to the inner wall of the washing drum 23, preventing the ferric phosphate from clogging the through-holes in the washing drum 23 and preventing the cleaning solution from entering the washing drum 23. The device vibrates during operation, and this vibration pushes the support legs. The lower slide plate 32 slides in the fixed frame 31, and the convex plates 33 at both ends of the slide plate 32 slide in the rectangular groove 34. The convex plates 33 compress the damping rod 35 and the spring 36. The damping rod 35 and the spring 36 can buffer and reduce the shock of the device. By setting the shock absorption component 3, the device can buffer and reduce the shock, and improve the practicality of the equipment. By fixing the vertical plate 37 at the lower end inside the fixed frame 31, the slide plate 32 can be limited to avoid the slide plate 32 shaking too much and causing damage to the damping rod 35. At the same time, the rubber strip 38 set at the upper end of the vertical plate 37 can buffer the contact between the slide plate 32 and the vertical plate 37.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
