Weighing pressure-tight belt coal feeder is used on the batching feeding of the power plant or coal feeding applications in other industries. The feeding process is a continuous belt feeding process. The feeder will feed the materials from the customer’s feed hopper or other feed equipments and weigh the weight of the materials through the weighbridge. Meanwhile, the speed sensor in the tail roller measures the speed of the belt. The measured weight signals and speed signals are sent into the 6105B integrator together for the calculous calculation and the instantaneous flow rate in ton/hour unit and the totals in ton unit will be displayed. The inner adapter compares the measured instantaneous flow rate signal values with the preset flow rate values from the computer through the communication board, outputs the

relevant signal values based on the deviation, changes the rotate speed of the motor and make the feed rate same with the preset ones through the transducer and thus complete the control of the invariable feed rate. The total signals are sent into the computer for setting the stop function when the total reaches the standards. Conveyance and measurement are both carried out in the solid pressure tight body. There is a sweep-cleaning device, which can clean the spilled material and the fly ash to the coal discharger, in the lower part of the conveyance and measurement part.

will then be kept on, circuit connected with LED on. ◆when the switch is on, if the metallic button is pressed hard, after it is released, the switch will then be unlocked and kept off with LED accordingly off. ◆when the switch is on, if the metallic button is pressed gently, LED will be off immediately, but after the button is released, LED will then be on again, and the switch will then be kept on. This operation is defined as the “gentle pressing” that LED goes through momentary on-and-off as the metallic button is gently pressed and released. ●how to switch over If the torch is turned on for the first time, or turned on again after it is turned off for the first time and remains off or at least 2 seconds, the gear will then be automatically switched to the first gear in either case: “high light”. In the mode that the torch is kept on when LED is on, press the tail switch gently, and the torch will be switched to another gear. The 8 different gears assembled herein will be switched on by turns. Caution: if you have any problem with switchover before initial use, please contact relevant salespeople or the after-sale service department for more information. 3. Load batteries in the right way Unscrew the tail cover, put the batteries into the cabin with the positive electrode toward the torch head, and then screw the cover tight. If batteries are loaded in the wrong way, the torch won’t work due to circuit protection, but it will resume normal work after batteries are unloaded and reloaded in the right way. Caution: batteries with no-load voltage over 2V are not preferred in case the internal circuit suffers from damages. Only batteries with on-load voltage of or under 2V are recommended. Due to excellent discharging performance, NiMH batteries are strongly recommended here. Maintenance Four silicone rings are equipped, two in front of the middle pipe and two at the back, providing excellent water-proof performance. For daily use, the torch will continue normal work even if it is accidentally soaked in the water.

一、概述 我公司生产的甲带给料机是根据专利技术研制开发的新型产品,于2002年7月通过了山东科技厅组织的科技成果鉴定(鲁科成鉴字2002第341号),主要用于国民经济生产各部门物料传送系统中料仓的给料,克服了目前给料系统中广泛使用的往复式和振动式给料机的缺点,改间断给料方式为连续给料方式,变恒定给料量为根据用户需要,给料量动态连续可变,使给料系统更能满足高效、节能、环保的要求。 目前,料仓给料系统中所使用的给料机主要有K型往复式和振动式给料机(见煤矿机械设备选型手册和各生产厂产品样本),两种给料方式的给料机,其结构及工作原理是:在料仓下部设一导料槽,导料槽底板为活动式,用一动力装置带动底板循环往复运动,当底板向给料口方向运行时,物料随底板一起运动,完成给料过程;当底板向反方向运行时,物料在内压力及内外摩擦力的共同作用下,物料并不随底板一起运动;底板不断循环往复运动,仓内物料不断的被送往出料口。两种给料方式的不同点是,给料频率和幅值及运动轨迹的不同。 K型往复式给料机的缺点是:给料机底板在回程中需承受物料很大的摩擦力,所以需要较大的驱动功率,能耗大;由于功率大,结构受力也大,设备重量大;由于给料过程是往复运动,设备振动大,噪音也大;由于结构受力大,运动件磨损快,维修量大;由于给料不连续,生产率较低。 振动式给料机的缺点是:由于给料频率高,噪音也大;由于是靠高频振动给料,其振幅和频率受物料粒度及比重影响较大,所以给料量不稳定,给料量的调整也比较困难;由于是靠振动给料,给料机必须起振并稳定在一定的频率和振幅,但振动参数对底板受力状态很敏感,故底板不能承受
