[0036] During use, a certain amount of flocculant can be evenly spread inside the sedimentation tank 1 as needed, and stirred simultaneously, and aerated while stirring, and the stirring range can be increased to make the stirring process more sufficient;

[0037] When in use, the main motor 34 can drive the rotating shaft 32 to rotate, and the rotating shaft 32 drives the spiral blade 33 to rotate clockwise. At this time, the spiral blade 33 can continuously flip and transport the coal slurry water upward to form a stirring effect; while the spiral blade 33 is transporting, flipping and stirring the coal slurry water, the fixed blade 352 and the extended blade 357 will further stir the coal slurry water at the same time; in the process of the stirring component 35 and the spiral blade 33 stirring the coal slurry water, the turbine air pump 363 can transport air through the air supply pipe 362, and the air flow passes through the space between the movable plate 31, the guide frame 361 and the rotating shaft 32, and flows into the hollow groove 364 from the connecting hole 365, and then flows into the discharge material through the hollow groove 364 378 and the movable column 376 move downwards, and the push spring 379 is compressed, and the opening of the discharge channel 373 is partially connected to the inside of the air supply pipe 362. The greater the wind force, the larger the opening of the discharge channel 373 communicating with the inside of the air supply pipe 362. On the contrary, the smaller the air flow, the smaller the discharge channel 373 communicating with the inside of the air supply pipe 362. The smaller the opening of the connection is, the smaller it is until it is reduced to a closed state. At this time, the flocculant is not added. The size of the different air flows makes the discharge channel 373 and the inside of the air supply pipe 362 form different opening sizes, so that the flocculant in the material box 372 flows into the inside of the air supply pipe 362 from the opening of the discharge channel 373 through the conduit 371, so that the flow rate of the flocculant into the air supply pipe 362 can be controlled by the wind force blown by the turbine air pump 363. The flocculant flows from the cavity formed by the movable plate 31, the guide frame 361 and the rotating shaft 32 into the inside of the connecting hole 365, flows from the inside of the hollow groove 364 into the inside of the discharge hole 351, and finally flows from the spaced holes 354 on the outer surface of the rotating fixed leaf 352 to the At the same time, according to the different speeds of the main motor 34, the extended leaf 357 can be thrown outward from the inside of the fixed leaf 352. At this time, the reset spring 356 is stretched, and the number of the spacing holes 354 connected to the inside of the rotating shaft 32 is increased, so that the flocculant can flow out from different openings of the spacing holes 354, increasing the position where the flocculant reacts with the coal slurry water. At the same time, the extension of the extended leaf 357 can enhance the stirring effect, and the air flow blown by the turbine air pump 363 can further blow out the flocculant, promote the reaction process, enhance the reaction effect, and improve the sedimentation efficiency.

[0038] Example 3

[0039] like Figure 2 As shown, on the basis of Example 2, it is further proposed that the movable structure 4 includes a longitudinal electric slide rail 41, the number of the longitudinal electric slide rail 41 is two groups, and the two groups of longitudinal electric slide rails 41 are fixedly connected to the sedimentation tank 1 and the footbridge 2 respectively, the outer surface of the longitudinal electric slide rail 41 is slidably connected with a longitudinal electric slider 42, the outer surface of the longitudinal electric slider 42 is fixedly connected with a transverse electric slide rail 43, the outer surface of the transverse electric slide rail 43 is slidably connected with a transverse electric slider 44, and the outer surface of the transverse electric slider 44 is fixedly connected with a support plate 45; the number of the movable structure 4 is two groups, and one group of movable structures 4 corresponds to two groups of transverse electric slide rails 43, and the two groups of transverse electric slide rails 43 are parallel, the longitudinal electric slider 42 is an arc-shaped plate structure, the outer surface of the movable plate 31 is penetrated and connected with a connecting bolt 38, and the support plate 45 and the movable plate 31 are movably connected by the connecting bolt 38;

[0040] When in use, the stirring structure 3 can stir different parts of the sedimentation tank 1, so that the effect of settling the coal slurry flocs after stirring is better, which is beneficial to the rent stirring process;

[0041] During the entire use of the equipment, the longitudinal electric slider 42 and the transverse electric slider 44 move on the longitudinal electric slide rail 41 and the transverse electric slide rail 43 respectively, so that the entire stirring structure 3 can be located at different orientations inside the sedimentation tank 1, so that different areas inside the sedimentation tank 1 can be stirred and mixed, thereby enhancing the reaction between the flocculant and the coal slime water, thereby promoting the entire sedimentation process.

[0042] In summary, the use process and working principle of the present invention are as follows:

[0043] When in use, after the coal washing tailings slime water is stored in the sedimentation tank 1, the main motor 34 is operated to drive the rotating shaft 32 to rotate, and the rotating shaft 32 drives the spiral blade 33 to rotate clockwise. At this time, the spiral blade 33 can continuously turn the coal slime water upward and transport it to form a stirring effect;

[0044] While the spiral blades 33 are transporting, stirring and agitating the coal slurry, the fixed blades 352 and the extended blades 357 are further agitating the coal slurry.

[0045] During the process of stirring the coal slurry water by the stirring assembly 35 and the spiral blades 33, the turbine air pump 363 can deliver air through the air supply pipe 362. The air then passes through the space between the movable plate 31, the guide frame 361 and the rotating shaft 32, flows into the hollow groove 364 from the connecting hole 365, and then flows into the discharge hole 351 through the hollow groove 364. Finally, it flows out from the chute 353 through the spacing holes 354 in sequence. This can enhance the stirring effect of the equipment on the coal slurry water and make the reaction between the flocculant and the coal slurry water more sufficient.

[0046] It should be noted that when the air flow is delivered to the inside of the air supply pipe 362 by the turbine air pump 363, the air flow will blow the sliding ring 377 downward, so that the sliding ring 377 drives the movable baffle 378 and the movable column 376 to move downward. At this time, the push spring 379 will be compressed, and the opening of the discharge channel 373 will be partially connected to the inside of the air supply pipe 362. The greater the wind force, the larger the opening of the discharge channel 373 communicating with the inside of the air supply pipe 362. Conversely, the smaller the air flow blows, the smaller the opening of the discharge channel 373 communicating with the air supply pipe 362, until it is reduced to a closed state. At this time, the flocculant is not added. The discharge channel 373 and the air supply pipe are connected by different air flow sizes. Different opening sizes are formed inside 362, so that the flocculant in the material box 372 flows into the interior of the air supply pipe 362 from the opening of the discharge channel 373 through the conduit 371, so that the flow rate of the flocculant into the air supply pipe 362 can be controlled by the wind force blown by the operation of the turbine air pump 363. The flocculant flows into the interior of the communication hole 365 from the cavity formed by the movable plate 31, the guide frame 361 and the rotating shaft 32, flows into the interior of the discharge hole 351 from the interior of the hollow groove 364, and finally flows out from the spaced holes 354 on the outer surface of the rotating fixed blade 352. In this way, the flocculant can be evenly scattered inside the coal slurry water, and the stirring effect forms a sufficient mixture to promote flocculation.

[0047] At the same time, during use, according to the different speeds of the main motor 34, the extended leaf 357 can be thrown outward from the inside of the fixed leaf 352. At this time, the reset spring 356 is stretched, and the number of spacing holes 354 connected to the inside of the rotating shaft 32 increases, so that the flocculant can flow out from different openings of the spacing holes 354, increasing the locations where the flocculant reacts with the coal slime water. At the same time, the extension of the extended leaf 357 can enhance the stirring effect, and the air flow blown by the turbine air pump 363 can further blow out the flocculant, promote the reaction process, enhance the reaction effect, and improve the sedimentation efficiency.

[0048] It should be noted that during the entire use of the equipment, the longitudinal electric slider 42 and the transverse electric slider 44 are moved on the longitudinal electric slide rail 41 and the transverse electric slide rail 43 respectively, so that the entire stirring structure 3 can be located at different orientations inside the sedimentation tank 1, so that different areas inside the sedimentation tank 1 can be stirred and mixed, thereby enhancing the reaction between the flocculant and the coal slime water, thereby promoting the entire sedimentation process.

[0049] It should be noted that when the airflow does not blow the sliding ring 377, the sliding ring 377 and the movable baffle 378 will be pushed upward under the reaction force of the push spring 379, so that the movable baffle 378 closes the hole connecting the discharge channel 373 with the inside of the turbine air pump 363, thereby preventing the flocculant from falling into the interior of the sedimentation tank 1 when the equipment is not in use or not blown.

[0050] It should be noted that when the stirring structure 3 is close to the edge of the inner wall of the sedimentation tank 1, the speed of the main motor 34 will decrease. At this time, the return spring 356 will shrink, pulling the extended leaf 357 to move toward the side of the fixed leaf 352, thereby reducing the length of the fixed leaf 352 together with the extended leaf 357, and avoiding interference between the extended leaf 357 and the inner wall of the sedimentation tank 1.

[0051] It should be noted that the flocculant used in the present invention is applicable to liquid or powdered flocculant materials.

[0052] It should be noted that the present invention can increase the stirring area and region while stirring, and can blow in air flow to enhance the reaction effect. At the same time, the amount of flocculant added can be controlled according to the size of the blown air volume, which can make the use effect of the sedimentation equipment better.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
