Description

Calcium superphosphate apparatus for producing with multistage broken mechanism Technical Field The invention relates to the technical field of crushers, in particular to a calcium superphosphate production device with a multi-stage crushing mechanism. Background The production process of the superphosphate serving as an important chemical fertilizer generally comprises core processes of grinding, mixing reaction, solidification, crushing, sieving and the like of phosphate rock powder, wherein the crushing process directly influences the granularity uniformity of the superphosphate product, and further determines the subsequent sieving efficiency and the application effect of the final product. Therefore, the performance of the crushing device has a key influence on the overall efficiency, product quality and production cost of the superphosphate production, and developing a high-efficiency, stable and low-loss superphosphate crushing device becomes an important requirement in the industry. Currently, the existing superphosphate crushing apparatus mainly adopts a single-stage crushing structure, and common types include hammer crushers, extrusion crushers and the like. The hammer crusher drives the hammer head to rotate at a high speed through a motor, and utilizes the impact force of the hammer head to crush the calcium superphosphate, and the extrusion crusher realizes crushing through the cooperation of two extrusion rollers or conical heads which rotate relatively and the lining and utilizing extrusion acting force. However, these prior art techniques gradually expose a number of insurmountable drawbacks during practical application, as follows: first, the crushing efficiency is low and the uniformity of particle size is poor. The existing device adopts a single-stage crushing mode, so that the calcium superphosphate is difficult to fully crush. For example, single hammer crushing has insufficient crushing strength on large-sized superphosphate, is easy to generate the conditions of crushing or incomplete crushing, and single extrusion crushing has poor adaptability on superphosphate with stronger viscosity or uneven particle size, is easy to cause larger fluctuation of the particle size of the crushed product, and cannot meet the accurate requirement of the subsequent production process on the particle size of the raw material. Meanwhile, the layout of the crushing assemblies of the partial device is unreasonable, a crushing blind area exists, the crushing efficiency is further reduced, and the burden of the subsequent screening process is increased. Secondly, accumulation and retention problems are easy to occur in the blanking process. The superphosphate raw material is usually in a block shape or a particle shape before being crushed, and part of the raw material also has certain viscosity, so that the superphosphate raw material is very easy to accumulate and stay on the surface of a material guide plate in the guide conveying process through a material discharging hopper, thereby blocking a material discharging channel and affecting the production continuity. Although the existing device is partially provided with the vibration blanking structure, the vibration blanking structure is realized by additionally arranging the vibration motor, so that the structural complexity and the energy consumption of the device are increased, and the problem of accumulation cannot be thoroughly solved due to poor vibration auxiliary blanking effect caused by mismatching of vibration frequency and blanking speed. Thirdly, in extrusion formula breaker, the extrusion process of conical head and inside lining can produce great rigidity impact, and current device does not be provided with effectual buffer structure mostly, or only adopts simple elastic pad to cushion, can't fully absorb impact force, leads to key parts such as inside lining, conical head and support base to bear high frequency impact for a long time, and the wearing and tearing speed is fast, and life shortens by a wide margin. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a calcium superphosphate production device with a multi-stage crushing mechanism, which solves the problems in the prior art. The scheme for solving the technical problems is as follows: The invention provides a calcium superphosphate production device with a multistage crushing mechanism, which comprises a supporting base, a crushing assembly, an upper cover, a discharging hopper, a first discharging assembly, a second discharging assembly and a transmission assembly, wherein the upper cover is arranged on the supporting base; The inner lining and the rotating base are arranged in the supporting base, the conical head is rotatably arranged on the rotating base, the conical head is positioned in the inner lining and is eccentrically arranged, and the end face gear ring is arranged on the lower surface of the conical head; The crushing assembly
