[0022] The liquid injection group includes a plug-in cylinder 13 inserted into the rotating cylinder 4, the plug-in cylinder 13 passes through the nozzle 5 and extends to the inside of the cleaning box 11, the plug-in cylinder 13 is sleeved on the outside of the liquid injection tube 7, and the outer wall of the plug-in cylinder 13 is provided with openings 25 located inside the nozzle 5 at equal distances, and the plug-in cylinder 13 is provided with a guide seat 24 located on one side of the opening 25, and the guide seat 24 is a conical structure;

[0023] After the staff puts the filter residue into the cleaning box 11, the liquid in the liquid storage tank 6 is injected into the plug-in tube 13 through the injection tube 7. Then the liquid passes through the opening 25 and enters the nozzle 5 through the diversion effect of the diversion seat 24, and is sprayed into the cleaning box 11 through the nozzle 5, effectively flushing the filter residue, thereby realizing the flushing and purification operation of the wet phosphoric acid filter residue.

[0024] The driver includes a motor 14 installed at the top of the plug-in cylinder 13, and the output shaft of the motor 14 is connected to the plug-in cylinder 13 and the rotating cylinder 4 through a bevel gear transmission 15.

At the same time, the rotating cylinder 4 will drive the nozzle 5 to rotate, so that the nozzle 5 rotates to spray liquid, thereby increasing the spraying range of the liquid and the washing range of the filter residue, thereby improving the washing efficiency of the filter residue, and providing power for the action of the material-dispensing mechanism, so as to facilitate the material-dispensing of the filter residue, realize comprehensive washing of the filter residue, and effectively improve the washing quality of the filter residue.

[0025] The shaking mechanism includes a stabilizing rod 19 installed inside the sliding mouth 18, a sliding seat 20 is sleeved outside the stabilizing rod 19, and a spring 21 connected to the bottom end of the sliding seat 20 and the bottom end of the sliding mouth 18 is sleeved on the stabilizing rod 19, and a motor 22 is symmetrically installed on both sides of the flushing box 1, and a cam 23 is connected to the output shaft of the motor 22, and the long end of the outer wall of the cam 23 is in sliding contact with the bottom end of the sliding seat 20;

[0026] When the filter residue is placed in the cleaning box 11, the motor 22 is started, and the motor 22 drives the cam 23 to rotate. When the outer wall long end of the cam 23 rotates upward, the outer wall of the cam 23 pushes the slide 20 to move up, and the slide 20 slides on the stabilizing rod 19. At the same time, the slide 20 drives the cleaning box 11 and the fixed rod 10 to move up, and the material-dispensing mechanism moves up synchronously, which makes the spring 21 produce elastic force. As the cam 23 continues to rotate, when the outer wall long end of the cam 23 rotates downward, the outer wall of the cam 23 is separated from the contact with the bottom end of the slide 20, and then under the reverse action force of the spring 21, the cleaning box 11, the fixed rod 10 and the material-dispensing mechanism move downward synchronously, and then the reciprocating shaking of the cleaning box 11 is realized, and the cleaning box 11 drives the filter residue inside it to shake back and forth, which is convenient for changing the position of the filter residue, avoiding the filter residue from being stationary and affecting its washing efficiency, thereby effectively improving the washing quality of the filter residue.

The tops of the rotating rod 26 and the telescopic cylinder 9 are fixedly connected with a limiting block 27 extending to the inside of the limiting groove 28, and the limiting block 27 is slidably connected to the limiting groove 28.

[0028] When the nozzle 5 performs a rotary spraying flushing on the filter residue inside the cleaning box 11, the nozzle 5 will drive the rotating cylinder 8 to rotate synchronously. Through the connection relationship between the limit groove 28 and the limit block 27, the rotating cylinder 8 will drive the telescopic cylinder 9 to rotate synchronously. At the same time, the plug-in cylinder 13 will drive the rotating rod 26 to rotate synchronously. Since the rotating rod 26 and the telescopic cylinder 9 rotate in opposite directions, the rotating rod 26 will drive the rotating shaft 30 to rotate, and the rotating shaft 30 will drive the connecting seat 29 to rotate at the bottom of the telescopic cylinder 9. The connecting seat 29 will drive the scraper plate 16 to clean the filter residue in the middle of the bottom end of the cleaning box 11. The rotating shaft 30 drives the material shifting plate 31 to rotate with the rotating rod 26 as the axis, so that the material shifting plate 31 pushes the filter residue at the bottom of the cleaning box 11 to move, and through the connection relationship of the bevel gear transmission 17, the rotating shaft 30 rotates, and then the rotating shaft 30 drives the material shifting plate 31 to rotate, so that the material shifting plate 31 can intermittently flip the filter residue, and then change the position of the filter residue, effectively avoid the filter residue from being stationary, and then provide convenience for comprehensive flushing of the filter residue, improve the flushing quality of the filter residue, and improve the washing and purification efficiency of the wet phosphoric acid filter residue.

[0029] The implementation principle of a wet-process phosphoric acid residue flushing and purification device in the embodiment of the present application is as follows: after the staff puts the residue into the cleaning box 11, the liquid in the liquid storage tank 6 is injected into the plug-in cylinder 13 through the liquid injection pipe 7, and then the liquid passes through the opening 25 and enters the nozzle 5 through the diversion effect of the diversion seat 24, and is sprayed into the cleaning box 11 through the nozzle 5.

At the same time, the rotating cylinder 4 will drive the nozzle 5 to rotate, which is convenient for the nozzle 5 to rotate and spray the liquid, thereby increasing the spraying range of the liquid and the flushing range of the residue, thereby improving the flushing efficiency of the residue.

[0030] At the same time, motor 22 is started, and motor 22 drives cam 23 to rotate. When the outer wall long end of cam 23 rotates upward, the outer wall of cam 23 pushes slide seat 20 to move up, and slide seat 20 slides on stabilizing rod 19. At the same time, slide seat 20 drives cleaning box 11 and fixing rod 10 to move up, and makes the material dispensing mechanism move up synchronously, which makes spring 21 produce elastic force. As cam 23 continues to rotate, when the outer wall long end of cam 23 rotates downward, the outer wall of cam 23 is separated from the contact with the bottom end of slide seat 20, and then under the reverse action force of spring 21, the cleaning box 11, fixing rod 10 and material dispensing mechanism move down synchronously, and then the reciprocating shaking of cleaning box 11 is realized, and cleaning box 11 drives the filter residue inside it to shake reciprocally, which is convenient for changing the position of filter residue, avoiding the filter residue from being stationary and affecting its washing efficiency, and then effectively improving the washing quality of filter residue.

[0031] When the nozzle 5 performs a rotary spraying flushing on the filter residue inside the cleaning box 11, the nozzle 5 will drive the rotating cylinder 8 to rotate synchronously. Through the connection relationship between the limit groove 28 and the limit block 27, the rotating cylinder 8 will drive the telescopic cylinder 9 to rotate synchronously. At the same time, the plug-in cylinder 13 will drive the rotating rod 26 to rotate synchronously. Since the rotating rod 26 and the telescopic cylinder 9 rotate in opposite directions, the rotating rod 26 will drive the rotating shaft 30 to rotate, and the rotating shaft 30 will drive the connecting seat 29 to rotate at the bottom of the telescopic cylinder 9. The connecting seat 29 will drive the scraper plate 16 to clean the filter residue in the middle of the bottom end of the cleaning box 11. The rotating shaft 30 drives the material shifting plate 31 to rotate with the rotating rod 26 as the axis, so that the material shifting plate 31 pushes the filter residue at the bottom of the cleaning box 11 to move, and through the connection relationship of the bevel gear transmission 17, the rotating shaft 30 rotates, and then the rotating shaft 30 drives the material shifting plate 31 to rotate, so that the material shifting plate 31 can intermittently flip the filter residue, and then change the position of the filter residue, effectively avoid the filter residue from being stationary, and then provide convenience for comprehensive flushing of the filter residue, improve the flushing quality of the filter residue, and improve the washing and purification efficiency of the wet phosphoric acid filter residue.
