The screening mechanism 2 screens the slurry, enabling the slurry to be evenly screened and greatly improving the screening efficiency of the screening mechanism 2. Moreover, an iron removal mechanism 3 is arranged between the screening mechanism 2 and the base 1, so that the screened slurry can continue to enter the iron removal mechanism 3, and the iron in the slurry is removed by the iron removal mechanism 3, thereby enabling both the screening process and the iron removal process of the slurry to be processed by this iron removal device for slurry screening, and further greatly improving the processing efficiency of the slurry and saving the processing time of the slurry.

[0041] In an embodiment of the present application, the driving member 11 is a vibration motor. By setting the vibration motor, on the one hand, it can make the screening of the slurry by the screening mechanism 2 more uniform, and on the other hand, it can make the slurry pass through the iron removal mechanism 3 evenly for iron removal.

[0042] As Figure 1 and Figure 3 shown, in some embodiments, the iron removal mechanism 3 includes a material passing bin and a magnetic attracting member 32. The material passing bin is inclined and fixed on the base 1;

[0043] An inclined groove 31 is provided in the material passing bin.

[0044] By inclinedly arranging the inclined groove 31 fixed on the base 1, the slurry entering the inclined groove 31 can slide to the discharge end along the inclined inclined groove 31. In an embodiment of the present application, the magnetic attracting member 32 is located at the discharge end of the inclined groove 31, so that the iron in the slurry is adsorbed by the magnetic attracting member 32 arranged on the side close to the discharge end, thereby realizing the removal of iron in the slurry.

[0045] Specifically, the inclined groove 31 is inclined and fixed on the base 1, and the inclination angle of the inclined groove 31 is 5° - 7°.

[0046] In addition, in some embodiments, a slurry outlet 37 is provided at the opening of the discharge end of the inclined groove 31, and the slurry flows out through the slurry outlet 37.

[0047] As Figure 1 and Figure 3 shown, in some embodiments, a fixed buckle 33 is fixedly arranged in the inclined groove 31, and the magnetic attracting member 32 is fixed to the fixed buckle 33.

[0048] By fixedly arranging the fixed buckle 33 in the inclined groove 31, the magnetic attracting member 32 can be quickly installed and disassembled in the inclined groove 31, greatly improving the installation and disassembly efficiency of the magnetic attracting member 32 and facilitating the replacement of the magnetic attracting member 32.

[0049] Specifically, the fixing buckle 33 is provided with a clamping protrusion, and the clamping protrusion can clamp the magnetic member 32 on the fixing buckle 33.

[0050] In the embodiment of the present application, the magnetic member 32 is a 12000 Gauss magnet bar, and there are multiple magnetic members 32, and the multiple magnetic members 32 are arranged at intervals in the inclined groove 31 along the inclined direction of the inclined groove 31.

[0051] As Figures 1 - 2 shown, in some embodiments, the screening mechanism 2 includes a first screening component 21 and a second screening component 22. The first screening component 21 is fixed on the top of the iron removal mechanism 3, and the second screening component 22 is fixed on the top of the first screening component 21.

[0052] By setting the first screening component 21 and the second screening component 22, the slurry can be screened through the second screening component 22 and the first screening component 21 in sequence, greatly improving the screening effect and the quality of the slurry product. Moreover, through the second screening component 22, larger impurities in the slurry can be screened out first, so as to avoid direct impact of larger impurities on the first screening component 21, resulting in damage to the first screening component 21, and further greatly extending the service life of the first screening component 21.

[0053] As Figure 1 、 Figure 2 and Figure 4 shown, specifically, the first screening component 21 includes a first screen frame 211, a first screen mesh 212, a first fixing component 213 and a first baffle 214. The first screen frame 211 is fixed on the top of the iron removal mechanism 3, the first screen mesh 212 is fixed to the first screen frame 211 through the first fixing component 213, and first baffles 214 are fixedly arranged on both sides of the first screen frame 211 along its width direction.

[0054] Fixing the first screen mesh 212 to the first screen frame 211 through the first fixing component 213 can, on the one hand, stably fix the first screen mesh 212 on the first screen frame 211 to prevent the first screen mesh 212 from falling off the first screen frame 211 and affecting the screening quality of the slurry. On the other hand, it can enable the first screen mesh 212 to be quickly disassembled and replaced on the first screen frame 211 through the first fixing component 213, greatly accelerating the maintenance efficiency and installation efficiency of the first screen mesh 212. In addition, by fixedly arranging first baffles 214 on both sides of the first screen frame 211 along its width direction, it can prevent the slurry from falling out of the first screen frame 211, enabling the slurry to be fully screened by the first screen mesh 212.

[0055] Specifically, the first fixing component 213 includes a first fixing base 2131, a first screw 2132, and a first nut 2133. The first fixing base 2131 is fixed to the first sieve frame 211, the first screw 2132 is fixed to the first fixing base 2131, the first nut 2133 is threadedly connected to the first screw 2132, and the first sieve mesh 212 is fixed to the first fixing base 2131 through the first nut 2133.

[0056] As Figure 1 , Figure 2 and Figure 5 shown, specifically, the second screening component 22 includes a second sieve frame 221, a second sieve mesh 222, a second fixing component 223, and a second baffle 224. The second sieve frame 221 is fixed to the top of the first baffle 214, the second fixing component 223 fixes the second sieve mesh 222 to the second sieve frame 221, and second baffles 224 are fixedly arranged on both sides of the second sieve frame 221.

[0057] Fixing the second sieve mesh 222 to the second sieve frame 221 through the second fixing component 223 can, on the one hand, stably fix the second sieve mesh 222 on the second sieve frame 221, preventing the second sieve mesh 222 from falling off the second sieve frame 221 and affecting the screening quality of the slurry. On the other hand, it can enable the second sieve mesh 222 to be quickly disassembled and replaced on the second sieve frame 221 through the second fixing component 223, greatly accelerating the maintenance efficiency and installation efficiency of the second sieve mesh 222.

[0058] Specifically, the second fixing component 223 includes a second fixing base 2231, a second screw 2232, and a second nut 2233. The second fixing base 2231 is fixed to the second sieve frame 221, the second screw 2232 is fixed to the second fixing base 2231, the second nut 2233 is threadedly connected to the second screw 2232, and the second sieve mesh 222 is fixed to the second fixing base 2231 through the second nut 2233.

[0059] In some embodiments, a plurality of first sieve holes are formed in the first sieve mesh 212, a plurality of second sieve holes are formed in the second sieve mesh 222, and the aperture of the first sieve holes is smaller than the aperture of the second sieve holes.

[0060] By setting the aperture of the first sieve holes to be smaller than the aperture of the second sieve holes, after the slurry is screened through the second sieve holes to screen out larger impurities, and then screened through the first sieve holes to screen out smaller impurities. On the one hand, it can prevent larger impurities from directly impacting the first sieve mesh 212, resulting in damage to the first sieve mesh 212, and thus greatly extending the service life of the first screening component 21. On the other hand, through multiple screenings, the impurities in the slurry can be screened more cleanly, thereby greatly improving the product quality of the slurry.

[0061] In the embodiments of the present application, the first sieve frame 211 and the second sieve frame 221 are also inclined downward from top to bottom, so that the slurry flows downward along the second sieve frame 221 under the action of gravity, and the slurry enters the first sieve frame 211 through screening by the second sieve mesh 222. The slurry flows downward along the first sieve frame 211 under the action of gravity and enters the material passing bin through screening by the first sieve mesh 212 of the slurry.

[0063] By arranging the first diversion plate 35 at the bottom of the highest end of the first sieve frame 211 in the vertical direction, it can be ensured that the slurry after being screened by the first sieve mesh 212 can enter the inclined groove 31.

[0064] In some embodiments, the diversion assembly further includes a second diversion plate 36. The second diversion plate 36 is arranged at the bottom of the first sieve frame 211. One end of the second diversion plate 36 is fixedly connected to the lowest end of the first sieve frame 211 in the vertical direction. The other end of the second diversion plate 36 is located in the inclined groove 31 and on the side of the magnetic attracting member 32 away from the discharge end. There is a gap between the second diversion plate 36 and the inclined groove 31.

[0065] By arranging the second diversion plate 36, on the one hand, it can make the slurry after being screened by the first sieve mesh 212 enter the inclined groove 31 through the second diversion plate 36, and on the other hand, it can make the slurry after being screened by the first sieve mesh 212 pass through the magnetic attracting member 32 and flow out from the discharge end, greatly improving the iron removal effect of the magnetic attracting member 32 on the slurry.

[0066] In addition, as Figure 1 、 Figure 2 and Figure 6 shown, in some embodiments, the slurry screening and iron removal device further includes a buckle assembly 4.

[0068] The pull ring 42 and the pull rod 43 are arranged on the clamping seat 41. The pull rod 43 can pull the pull ring 42 so that the pull ring 42 is clamped with the connecting seat 44, thereby fixedly connecting the second screening assembly 22 with the first screening assembly 21 and fixedly connecting the first screening assembly 21 with the iron removal mechanism 3.

[0069] As Figures 1 - 2 shown, in some embodiments, the slurry screening and iron removal device further includes a fastening assembly 34. The screening mechanism 2 and the iron removal mechanism 3 are tightened and fixed by the fastening assembly 34.

[0070] Specifically, the fastening assembly 34 includes a fastening rod 341, a fastening nut 342 and a fastening seat 343.

The fastening rod 341 sequentially passes through the through holes in the two fastening seats 343. The fastening nut 342 is threadedly connected with the fastening rod 341. The fastening nut 342 is pressed and fixed with the two fastening seats 343 along the length direction of the fastening rod 341.

The other end of the first connecting portion 12 is fixedly connected with the iron removal mechanism 3, and the other end of the second connecting portion 14 is fixed to the ground.

[0072] By dividing the support legs into a first connecting portion 12 and a second connecting portion 14 and arranging an elastic member 13 between the first connecting portion 12 and the second connecting portion 14, when the driving member 11 drives the screening mechanism 2 to vibrate, relative vibrations will also occur between the first connecting portion 12 and the second connecting portion 14, making the screening of the slurry more uniform, thereby greatly improving the screening effect of the screening mechanism 2 on the slurry.

[0073] As Figures 1 - 2 shown, in some embodiments, universal wheels 15 are arranged at the bottom of the base 1.

[0074] By arranging the universal wheels 15, it is convenient to move the entire slurry screening and iron removal device, thereby greatly expanding the use range of the slurry screening and iron removal device and improving work efficiency.
