[0016] (3) Beneficial effects

[0017] Compared with the prior art, the utility model provides a multi-stage screening device for sulphoaluminate clinker powder, which has the following beneficial effects:

[0018] (1) The present invention adopts a screening cylinder. When the multi-stage screening device for sulfoaluminate clinker powder is actually used, the sulfoaluminate clinker powder can be put into the interior of the shaft tube through the feed hopper. The sulfoaluminate clinker powder inside the shaft tube can enter the interior of the screening cylinder. The control panel is used to operate the first electric telescopic rod, the electromagnet and the drive motor. The output end of the drive motor can drive the main gear to rotate. Since the main gear and the driven gear are engaged with each other, the rotating main gear can drive the driven gear to rotate. The rotating driven gear can drive the screening cylinder and the socket plate to rotate through the shaft tube. The socket plate can stir and crush the sulfoaluminate clinker powder through two sets of stirring shafts. By using centrifugal force, the sulfoaluminate clinker powder can be multi-stage screened through the first-stage filter tube, the second-stage filter tube and the third-stage filter tube. When the screened sulfoaluminate clinker powder needs to be taken out, the first electric telescopic rod is retracted. The telescopic rod is movable. When the electromagnet moves to the appropriate position, the control panel can be used to energize the electromagnet. Multiple groups of sealing covers are made of iron material. The electromagnet can adsorb one group of sealing covers. This group of sealing covers and the two groups of T-shaped rods on the same side can squeeze the two groups of telescopic springs and the two groups of telescopic hoses on the same side. When this group of sealing covers moves out of the group of discharge ports on the same side, the sulfoaluminate clinker powder can be discharged through this group of discharge ports. Thereafter, the on-off valve is opened and closed to allow the sulfoaluminate clinker powder inside the box to be discharged through the discharge hopper. When the electromagnet is powered off, the two groups of telescopic springs on the same side are acted upon by their own elastic force to push the group of sealing covers on the same side to move into the inside of the group of discharge ports on the same side. The use of the remaining groups of sealing covers can be obtained by the same operation. The sulfoaluminate clinker powder can be screened into multiple stages through the provided screening cylinder, thereby improving the practicality of the multi-stage screening device for sulfoaluminate clinker powder.

[0019] (2) The present invention adopts a feed hopper. According to the above operation, the sulfoaluminate clinker powder needs to be placed inside the feed hopper. The control panel is used to shorten the second electric telescopic rod. When the blocking cover blocks the mounting hole plate, the sulfoaluminate clinker powder can be placed inside the feed hopper through the feed port. After the sulfoaluminate clinker powder is added, the control panel is used to extend the second electric telescopic rod. When the blocking cover is moved out of the mounting hole plate, the interception cover intercepts the feed port. Finally, the sulfoaluminate clinker powder accumulated on the upper part of the blocking cover will enter the interior of the shaft tube, and the dust will not be discharged through the discharge port. Through the set feed hopper, the sulfoaluminate clinker powder can be added without stopping the screening work, thereby improving the working efficiency of the multi-stage screening device for sulfoaluminate clinker powder.

[0036] Working principle:

[0037] When the multi-stage screening device for sulphoaluminate clinker powder is actually used, the sulphoaluminate clinker powder can be put into the interior of the shaft tube 2 through the feed hopper 14. The sulphoaluminate clinker powder inside the shaft tube 2 can enter the interior of the screening drum 3. The control panel is used to operate the first electric telescopic rod 10, the electromagnet 11 and the drive motor 16. The output end of the drive motor 16 can drive the main gear 17 to rotate. Since the main gear 17 and the driven gear 15 are engaged with each other, the rotating main gear 17 can drive the driven gear 15 to rotate. The rotating driven gear 15 can drive the screening drum 3 and the socket plate 4 to rotate through the shaft tube 2. The socket plate 4 can stir and crush the sulphoaluminate clinker through the two sets of stirring shafts 5. Powder, using centrifugal force, the sulphoaluminate clinker powder can be multi-stage screened through the first-stage filter tube 6, the second-stage filter tube 7 and the third-stage filter tube 8. When the sifted sulphoaluminate clinker powder needs to be taken out, the first electric telescopic rod 10 is extended and retracted. When the electromagnet 11 is moved to a suitable position, the control panel can be used to energize the electromagnet 11. Multiple groups of sealing covers 19 are made of iron material. The electromagnet 11 can adsorb a group of sealing covers 19. This group of sealing covers 19 and the two groups of T-shaped rods 20 on the same side can squeeze the two groups of telescopic springs 21 and the two groups of telescopic hoses 22 on the same side. When this group of sealing covers 19 moves out of a group of discharge ports 18 on the same side, the sulphoaluminate clinker powder can pass through this The sulphoaluminate clinker powder is discharged from the discharge port 18 of the group, and then the on-off valve is opened and closed, so that the sulphoaluminate clinker powder inside the box body 1 can be discharged through the discharge hopper 9. When the electromagnet 11 is powered off, the two groups of telescopic springs 21 on the same side are acted upon by their own elastic force to push the sealing cover 19 of the group on the same side to move into the interior of the discharge port 18 of the group on the same side. The use of the remaining groups of sealing covers 19 can be obtained by the same operation. The sulphoaluminate clinker powder can be screened into multiple levels by the screening cylinder 3 provided, thereby improving the practicality of the multi-stage screening device for sulphoaluminate clinker powder. At the same time, according to the above operation, the sulphoaluminate clinker powder needs to be put into the interior of the feed hopper 14, and the control panel is used to make the second electric telescopic rod 24 The sulphoaluminate clinker powder is shortened. When the blocking cover 27 blocks the mounting hole plate 28, the sulphoaluminate clinker powder can be put into the feed hopper 14 through the feed port 23. After the sulphoaluminate clinker powder is added, the control panel is used to extend the second electric telescopic rod 24. When the blocking cover 27 is moved out of the mounting hole plate 28, the interception cover 25 intercepts the feed port 23. Finally, the sulphoaluminate clinker powder accumulated on the upper part of the blocking cover 27 will enter the interior of the shaft tube 2, and the dust will not be discharged through the discharge port 18. Through the set feed hopper 14, the sulphoaluminate clinker powder can be added without stopping the screening work, thereby improving the working efficiency of the multi-stage screening device for sulphoaluminate clinker powder.
