Air cannon block clearer is a special device used to prevent and remove the material blast and block of all kinds of bunker , hopper , cement preheating furnace , pipeline y section and mine drawshaft and drawslope 空气炮清堵器是防止和消除各类型料仓，料斗、水泥预热器窑和管道分叉处及矿山溜井、溜坡的物料起拱，粘仓闭塞等现象的专用装置。
The machine unit is simple structured , compact , energy saving , convenient and simple for operation and maintenance , it ' s extensively adapted to materials , which could be used as ingredient storehouse after crushing , and process after using up the ingredient in machine 机组结构简单、紧凑、节能，操作维修方便，对物料适应性广，对小型养殖场，粉碎混合完一批后，可暂做存料仓使用，用完后再加工。
Meanwhile the influences of a hopper structure on the flow patterns of wet materials are different from dry materials . usually the critical open diameter of a hopper for dry particles is more than 3 times of particle diameter , but not less than 4 times for wet particles . for dry particles , the hopper angle which causes transformation from funnel flow into mass flow is about 45 同时料仓结构参数对干湿颗粒流动特性的影响也存在一些明显的差异：对于干颗粒，满足不结拱的料仓开口度尺寸至少为颗粒直径的三倍，而湿颗粒则要求料仓开口度至少为颗粒直径的四倍；干颗粒由漏斗流向整体流转换的角度在45度左右，而湿颗粒的转换角度为40度左右。
But there has been not correspondingly control system for it by far . ln this thesis a pulse nitrogenous conveying control system based on profibus is designed and achieved on the thinking of modularizing the pulse nitrogenous conveying system , which can be used for different the pulse nitrogenous conveying system and added new control cells . the thesis reviewed systematically the pulse nitrogenous conveying system in practical , and makes the understanding that the system is composed of standard gas storage cell , conveying equipment cell and target container ceil . then a common modularized control system project is designed and achieved by structurized programming orienting process , which consists of four control models , respectively for gas storage cell , for conveying equipment cell and for target container cell 本文综合实际使用的氮保护脉冲气力输送系统，把氮保护脉冲气力输送系统分为标准化的气源设备单元、发送设备单元和目的料仓设备单元，在此基础上，设计了用于氮保护脉冲气力输送系统的通用模块化控制方案，采用面向过程的结构化编程思想，基于profibus现场总线，实现了组成该方案的四类控制模块：气源单元控制模块、发送单元控制模块、目的料仓单元控制模块和通讯处理控制模块。
In order to solve the technological problem of the dredge of raw material flow on the production line , we ? e carried out as overall theoretical and experimental research on the movement characteristic of the raw material on the surface of sifter in the vibratory machine , the dynamics property of the vibration stimulated by inertial double - axes , the flow property of raw material in these store hoppers , the agglomeration and obstruction mechanism 针对生产实践急需，提出了本项研究题目。本文为了解决生产线物料流疏通的技术难题，对物料在振动筛分机筛面上的运动特性、双轴惯性激励式振动筛分机的动力学特性、储料仓内物料的流动特性、物料结拱及堵塞机理等进行了全面的理论分析和试验研究。
In the industrial process the material in the hopper always contains some water . with the aid of liquid bridge model , dem ( discrete element method ) and mathematical models , this paper firstly simulates the flow of wet particles in a hopper to study the influence of liquid bridge on the flow patterns and flow rate 针对这一情况，本文通过引入液桥力模型，结合离散颗粒法( dem ) ，首次用计算机模拟了料仓中湿颗粒的流动，研究了液桥力对料仓内颗粒流动形态以及质量流率的影响。
Wearproof porcelain plate developed by this factory can be used as inside lining plate , coal delivery pipework , bin , bunker , separation port , wind pipe bend , exhauster , inner pipe of mill fan , air preheater , air fule and various dedust equipment for antifriction . besides , it can extend the service life of equipment 耐磨瓷板系是我厂自行研制的适用于磨煤机内衬板，输煤管道、料仓、料斗、粗、细粉分离口、一、二次风管弯头、引风机、排粉机内壳、空气预热器、尾部烟道等以及各类除尘系统设备的防磨抗蚀、延长设备的使用寿命。
Integrated into a mechanism via network communication , the whole system combines with the periphery equipment to achieve the automatical control and management of the whole process including feeding , tranpotating and mixing from the outlet of silo to the outlet of mixer for the recipe need of dry mixed mortar ‘ s production 整个系统以网络通讯方式联系成一个有机整体，结合外围的执行设备完成对从料仓出口开始到混合机出口的配料输送混合的全过程的自动控制和管理，来满足干混沙浆生产对配料要求。
