TECHNICAL FIELD

[0001] The present application relates to the technical field of solid waste resource utilization, and in particular to an integrated small alkali residue slurry solid matter crushing device. BACKGROUND

[0002] In the industrialized production of alkali by the ammonia-soda process, a large amount of alkali residue is produced. At present, the main treatment method is landfill and stacking, which not only occupies land resources, but also may pollute the local soil due to its alkaline and high-salt characteristics. Therefore, the treatment of alkali residue is becoming a field of concern in environmental governance.

[0003] A large amount of solid matter in the alkali residue slurry is cemented, which greatly affects the treatment efficiency of the alkali residue. Therefore, it is necessary to pretreat the solid matter contained in the alkali residue slurry before the treatment process. The current crushing equipment is mainly used in industrial sites such as mines and is suitable for solid matter with strong rigidity. However, the solid matter in the alkali residue slurry has characteristics such as high water content and high viscosity, which easily causes the blocking problem of the crushing device.

[0016] Optionally, the upper side of the fine crusher is provided with a fine crushing guide hopper, and the fine crushing guide hopper is arranged to be gradually inclined downward towards the fine crusher.

[0017] By adopting the technical scheme, the fine crushing guide hopper guides the alkali residue slurry and reduces the situation that the alkali residue slurry directly impacts the fine crusher.

[0044] The implementation principle of the integrated small alkali residue slurry solid matter crushing device is as follows:

[0045] The alkali residue slurry enters the crushing device body 30 through the feeding pipe 1, is decompressed through the pressure reducing valve 2, and the impact of the slurry liquid is reduced. The alkali residue slurry is guided to the coarse crusher 5 through the feeding hopper 4. After being preliminarily crushed, the alkali residue slurry is discharged from the coarse crushing outlet 6 and enters the fine crushing guide hopper 7. The alkali residue slurry is guided to the fine crusher 8, and is crushed to meet the particle size of the slurry. The qualified slurry enters the storage tank 12 at the bottom of the crushing device body 30 through the fine crushing outlet 9. The alkali residue slurry is prevented from being deposited by being stirred by the stirring machine at the bottom of the storage tank 12. Finally, the slurry meeting the particle size is discharged through the discharge pipe 25 by the material conveying pump 23. In order to prevent the alkali residue slurry from blocking the coarse crusher 5 and the fine crusher 8, the washing water is washed to the running coarse crusher 5 and the fine crusher 8 through the washing nozzle.
