Description

Technical Field

[0001] The utility model relates to the technical field of cement manufacturing, in particular to an anti-blocking device for a cement discharger. Background Art

[0002] The cement production process can be simply referred to as "two grindings and one burning". The first is raw material grinding: after the raw materials are crushed or dried, they are mixed and ground according to a certain proportion to prepare raw materials with appropriate composition and uniform quality. This is called the first stage; the second is clinker calcination: the raw materials are added to the cement kiln and calcined until partially melted to obtain cement clinker with calcium silicate as the main component; the third is cement grinding, where an appropriate amount of gypsum is added to the clinker, and sometimes some mixed materials are added, and ground together into cement. The production links are: mining → crushing → pre-homogenization → batching → raw material grinding → raw material homogenization → suspension preheating, pre-decomposition, rotary kiln calcination → batching → cement grinding → cement homogenization → cement packaging and bulk delivery.

[0003] After searching, it was found that the announcement number is CN110155532B, and the name is a device for preventing the unloader from being blocked for cement production. The application proposes that when the homogenized cement is unloaded through the unloader, the unloader often gets blocked. Generally, when the unloader is blocked, the operator first confirms whether the unloader is placed stably, and then operates from the side of the unloader to avoid the raw material from spraying out and causing harm, and then unclogs the unloader. However, the working efficiency of this method is very low, and it also requires the staff to have a good sense of danger prevention. If they are not careful, the unblocking staff will be injured by the sprayed raw material. The problem of inconvenience in use can be solved by using movable rods, hinged rods, pressure plates, card plates, movable columns, card blocks and block blocks in combination, so that when the cement material is discharged from the unloader, there is no problem. The invention can automatically clear the discharge port effectively, and has the advantage of preventing the discharger from being blocked, ensuring that the discharger will not be blocked and no manual clearing is required, thereby ensuring the physical safety of the staff, improving work efficiency, and facilitating people's use. At the same time, through the coordinated use of the internal gear, the movable gear, the fixed gear and the fixed rod, the movable rod and the hinged rod on the left can be effectively made to move in opposite directions to the movable rod and the hinged rod on the right, providing energy for the clamping plate and the movable column to clear the discharge port. However, when used, this application adopts a complex gear connection structure, which is relatively complex and occupies a large amount of internal space, affecting the smoothness of unloading. Once a blockage occurs, the anti-blocking structure inside the discharger cannot be operated from the outside, resulting in a problem of ease of use. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

When the cement is unloaded, the raw cement is discharged from the discharge port 5 and hits the bottom cone 7. After the bottom cone 7 moves down, it moves up under the push of the first spring 9, forming an up and down bouncing movement, thereby driving the bottom rod 8 to move up and down. The bottom rod 8 pushes the inclined frame 12 to swing along the hinge seat 10. The other end of the inclined frame 12 drives the push rod 13 to move, pushes the push plate 14 and the moving rod 2 to move, drives the convex head 3 and the dredging rod 4 to move, and avoids blockage by disturbing the raw cement. 2. The convex head 3 and the dredging rod 4 occupy a small internal space of the discharger body 1, and the anti-blocking efficiency is high. At the same time, the device eliminates the complicated gear connection structure, the structure is simpler, and it is more convenient to use. At the same time, the push plate 14 is located outside the discharger body 1. Once the cement raw material is blocked and cannot be discharged from the discharge port 5, the bottom cone 7 fails. The staff can manually push the push plate 14 to drive the moving rod 2 to move to dredge the cement raw material, further avoiding the occurrence of blockage and further improving the convenience of use.

[0031] In one embodiment, a convex head 3 is fixedly sleeved on the outer surface of the moving rod 2 , and a plurality of convex heads 3 are arranged. The convex heads 3 facilitate the moving rod 2 to disturb the cement raw material inside the discharger body 1 when moving.
