Abstract
Description
Technical Field
[0001] The utility model relates to a slag lower hopper, in particular to a wet slag crushing slag lower hopper. Background Art
[0002] In hydrometallurgical zinc production, high-leaching residue and iron alum residue typically contain 25% water after filtration. This residue is prone to forming sticky residue before entering the drying kiln. This sticky residue will cling to the wall of the hopper as it passes through. This not only affects material discharge but also corrodes the hopper, requiring manual cleaning. This sticky residue is also prone to forming kiln agglomerates within the drying kiln. Once formed, this agglomeration not only significantly reduces drying efficiency but also causes localized temperature fluctuations in the kiln. When agglomeration reaches a certain level, the kiln must be shut down for processing, which is time-consuming and labor-intensive.
[0003] Therefore, there is an urgent need in the prior art for a wet slag crushing slag bucket that can improve the sticky slag hanging on the wall and slow down the speed of kiln agglomeration formation. Summary of the Invention
[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a wet slag crushing slag bucket which can improve the sticky slag hanging on the wall and slow down the speed of kiln agglomeration.
[0005] The object of the utility model is achieved through the following technical solutions: a wet slag crushing lower slag bucket, comprising an oblique bucket and a square bucket arranged at the upper end of the oblique bucket and penetrating the upper and lower parts of the oblique bucket, the oblique bucket comprising two front and rear upright side walls and two left and right inclined side walls, three rotating shafts are arranged in the oblique bucket, and these three rotating shafts can be rotatably installed between the two upright side walls, two of the rotating shafts are located at the left and right ends of the upper part of the oblique bucket and are respectively adjacent to the left and right inclined side walls, and the other rotating shaft is located in the middle of the lower port of the oblique bucket, each of the rotating shafts is fixed with a plurality of cutting plates perpendicular to the surface of the rotating shaft, these cutting plates are arranged in pairs, each pair of cutting plates is symmetrical up and down or front and back with the axis center of the rotating shaft as the axis of symmetry, and the two adjacent pairs of cutting plates on the left and right are staggered, three motors for driving the three rotating shafts are arranged on the outside of the oblique bucket, three support plates are fixed on the outside of the upright side walls, and the motors are installed on the corresponding support plates.
[0006] The inner sides of the two inclined side walls are both provided with a polytetrafluoroethylene plate lining.
[0007] A reinforcement cross beam and a reinforcement vertical beam are fixedly arranged at the top entrance of the square bucket.
[0008] The beneficial effects of this utility model are as follows: it can break up the sticky residue and improve the sticky residue sticking to the wall. Operators do not need to frequently clean the sticky residue on the inner wall of the lower hopper, which reduces the operator's labor intensity and reduces the safety hazards caused by cleaning the sticky residue. After the sticky residue is broken up, the speed of kiln slag formation in the drying kiln is slowed down, the drying effect of the drying kiln is guaranteed, and equipment damage caused by large local temperature changes is reduced.

[0013] The present invention will be described in detail below with reference to the accompanying drawings.
[0014] like Figure 1-3 As shown, a wet slag crushing lower slag bucket comprises an oblique bucket 4 and a square bucket 1 which is arranged at the upper end of the oblique bucket 4 and passes through the oblique bucket 4 up and down. The oblique bucket 4 comprises two front and rear upright side walls and two left and right inclined side walls. Three rotating shafts 6 are arranged in the oblique bucket 4. These three rotating shafts 6 can be rotatably installed between the two upright side walls. Two of the rotating shafts 6 are located at the left and right ends of the upper part of the oblique bucket 4 and are respectively adjacent to the left and right inclined side walls. The other rotating shaft 6 is located in the middle of the lower port of the oblique bucket 4. A plurality of cutting plates 7 perpendicular to the surface of the rotating shaft 6 are fixedly arranged on each rotating shaft 6. These cutting plates 7 are arranged in pairs, and each pair of cutting plates 7 is symmetrical up and down or front and back with the axis center of the rotating shaft 6 as the axis of symmetry. The two adjacent pairs of cutting plates 7 on the left and right are staggered. Three motors 5 for driving the three rotating shafts 6 are arranged on the outside of the oblique bucket 4. Three support plates 9 are fixedly arranged on the outside of the upright side walls, and the motors 5 are installed on the corresponding support plates 9.
[0015] During operation, the motor 5 drives the rotating shaft 6 to rotate, pouring the sticky residue from the upper port of the square bucket 1 into the utility model. The sticky residue then falls from the lower port of the inclined bucket 4, falls onto the belt conveyor, and is sent to the drying kiln. At the top of the inclined bucket 4, the cutting plates 7 of the two rotating shafts 6 adjacent to the left and right inclined side walls continuously stir the sticky residue to prevent it from sticking to the wall. At the same time, the cutting plates 7 arranged in pairs on the three rotating shafts 6 break up the sticky clumps formed by the sticky residue, preventing a large number of sticky clumps from entering the drying kiln, thereby slowing the formation of kiln clumps.
[0016] like Figure 2 As shown, the inner sides of the two inclined side walls are both provided with a PTFE plate lining 8, which is made of polytetrafluoroethylene resin, which has the characteristics of lubricity, non-adhesion and corrosion resistance, and can further reduce the wet slag hanging on the wall.
[0017] See also Figure 1-3 A reinforced crossbeam 2 and a reinforced vertical beam 3 are fixedly provided at the top entrance of the square bucket 1. The high leaching slag and iron alum slag are heavy. The reinforced crossbeam 2 and the reinforced vertical beam 3 can enhance the pressure-bearing strength of the square bucket 1 to prevent pressure deformation during use.
[0018] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
