Description

Horizontal crusher for compound fertilizer

Technical Field

The utility model belongs to the technical field of compound fertilizer processing equipment technique and specifically relates to a compound fertilizer is with horizontal breaker is related to.

Background

The compound fertilizer refers to a chemical fertilizer containing two or more nutrient elements. The fertilizer has the advantages of high nutrient content, high side components and good physical properties, can effectively improve the utilization rate of the fertilizer and promote the high and stable yield of crops, and is widely used in agricultural planting in China. In the processing process of the compound fertilizer, the raw materials of the compound fertilizer are easy to agglomerate, and before further processing, the agglomerated raw materials need to be crushed, so that the particles of the raw materials can meet the particle size of the processing requirement. The raw materials of the compound fertilizer are various nitrogen, phosphorus and potassium, such as: urea, ammonium nitrate, ammonium phosphate, ammonium sulfate, potassium chloride, potassium sulfide, and the like. Raw materials of the compound fertilizer are used as raw materials of the compound fertilizer and enter a crusher for crushing.

The existing crusher suitable for compound fertilizer processing is various in types, is mostly used by directly introducing mineral processing equipment or pharmaceutical processing equipment, and is poor in pertinence, and various different problems are easy to occur in different equipment in compound fertilizer processing. For example, the conventional chain crusher crushes the raw material of a compound fertilizer by applying an impact force to the incoming raw material of the compound fertilizer through a high-speed rotating endless chain. The particle size of the compound fertilizer raw material processed by the chain type crusher is determined by the layer number of the chains. The chain crusher has high speed and serious abrasion of the chain, and the chain needs to be replaced frequently in the using process. The wall is easily hung when some high-humidity compound fertilizer raw materials are crushed, the wall-hung compound fertilizer raw materials can corrode the inner walls of the chain and the wall breaking cylinder, and the motor is burnt out due to overlarge equipment load when the wall is serious.

The existing tooth-type wall breaking machine impacts and breaks raw materials of compound fertilizers through high-speed rotation of gears on carrier rollers. However, the tooth-type wall breaking machine is only suitable for coarse breaking of large-particle raw materials of compound fertilizers, and has poor effect and efficiency for breaking of raw materials of compound fertilizers with the particle diameter of less than or equal to 2mm, so that the processing requirement of the compound fertilizers cannot be met.

The existing hammer crusher generally adopts a vertical cylinder, adopts a feeding and discharging mode of straight up and straight down, and crushes materials passing through the cylinder by hanging a row of blades on a cutter shaft. When large granule feeding, hammer crusher's blade very easily damages, and hammer crusher's blade replacement rate is high moreover, short, crushing effect poor with the contact time of compound fertilizer raw and other materials, in order to guarantee crushing effect, needs set up the filter screen at the discharge gate of bottom. However, the arrangement of the filter screen can cause the material to be accumulated to block the outlet, and the blade positioned at the outlet is inevitably damaged.

In the existing compound fertilizer processing process, a roller press is also adopted for crushing materials, but the speed of the roller press is lower than that of other crushers, the crushing efficiency is low, the speed is low, and especially for some compound fertilizer raw materials with higher moisture requirements, the raw materials are easy to stick to walls, and mechanical faults are easily caused.

In conclusion, the hammer crusher, the chain crusher, the tooth-type wall breaking machine and the roller press are adopted to crush the raw materials of the compound fertilizer in the processing procedure of the compound fertilizer. The following problems arise with the above-described apparatus: firstly, the retention time of the raw materials of the compound fertilizer in the crusher is short, and the raw materials of the compound fertilizer cannot be fully and effectively contacted with crushing equipment, so that the effect after crushing is poor, and the particle diameter of the raw materials of the compound fertilizer after crushing cannot meet the requirement of the particle diameter required by the compound fertilizer; secondly, the crushing efficiency of the crusher on the raw materials of the compound fertilizer is too low to meet the requirement of compound fertilizer processing; thirdly, for some compound fertilizer raw materials with high humidity, the crusher is easy to break or the blades are damaged due to wall bonding, so that the subsequent maintenance cost of the equipment is high.

Because the spiral blades 42 and the crushing blades 43 in the crushing device 40 provide a driving force for moving the compound fertilizer raw materials towards the tail end in the rotating process of the rotating shaft 41, the compound fertilizer raw materials are easy to be stacked at the tail end of the horizontal cylinder 21, and even the problem of wall bonding is easy to be generated on the side wall of the discharge hole 23 of the horizontal cylinder 21. In order to prevent the problems of stacking, wall-bonding and wall-sticking of the raw materials of the compound fertilizer at the discharge port 23, the material shifting assembly 44 is arranged at the material shifting area 212 to turn the raw materials of the compound fertilizer in the area, so that smooth discharging at the discharge port 23 is ensured, and the material level in the whole horizontal cylinder 21 from the feed port 22 to the discharge port 23 is always kept at a stable material level height.

Specifically, in the material shifting area 212, each group of material shifting assemblies 44 is at least arranged at an interval of 100mm along the axial direction of the rotating shaft 41, that is, the distance between two adjacent groups of material shifting assemblies 44 is more than 100mm, so that a better material shifting effect can be achieved.

Specifically, as shown in fig. 5, each set of material ejecting assemblies 44 includes at least two material ejecting blades 441 perpendicular to the rotating shaft 41, and adjacent material ejecting blades 441 are arranged at an interval of at least 90 ° in the radial direction of the rotating shaft 41. In this embodiment, two groups of material ejecting assemblies 44 are disposed in the material ejecting zone 212, two material ejecting blades 441 are distributed in the same radial direction on each group of material ejecting assemblies 44, and the two material ejecting blades 441 are respectively spaced by 180 ° and 90 ° in the radial direction. Wherein, on a group of material stirring blades 441 close to the end wall of the horizontal cylinder 21, a scraping tooth 442 is further arranged on one side of the material stirring blades 441 close to the end wall, and wall materials on the end wall of the horizontal cylinder 21 can be scraped off through the scraping tooth 442 along with the rotation of the rotating shaft 41.
