自动上料搅拌车常见的问题是堵料问题,该如何避免这一情况呢?下面为大家介绍一下。
The common problem of automatic feeding mixer is material blockage. How to avoid this situation? Let's introduce it to you.
1、上下料时间参数不合理
1. Unreasonable loading and unloading time parameters
自动上料机因料仓内无法加装料位机,所以行业基本都有时间控制。如何设置时间参数,上下料时间设置其实很简单,在初次使用时,先设置一个小的时候,然后根据每次吸料位置慢慢加,当达到料位达到吸料口的时间,再减去一秒便是合理时间。放料时间是确保放完料再加一秒。这样做有两个好处:一是料位太高对滤芯伤害特别大,我们有些客户一个滤芯能用两年有些用半年也是这个原因。二是每次料都能放干净,下料阀在关闭的时候不会出现带料关阀,带料关阀对没分钟开关五六次的这种频繁工作的密封圈伤害特别大。
Since the automatic feeder cannot be equipped with a material level machine in the silo, the industry basically has time control. How to set the time parameter? The setting of loading and unloading time is actually very simple. In the first use, set an hour first, and then slowly add it according to each suction position. When the material level reaches the suction port, subtract one second to be a reasonable time. The discharging time is to ensure that one second is added after discharging. This has two advantages: first, too high material level will do great harm to the filter element. Some of our customers can use one filter element for two years and some for half a year. Second, the material can be discharged every time. When the blanking valve is closed, there will be no closing valve with material. The closing valve with material will do great harm to the sealing ring that works frequently without opening and closing five or six times a minute.
2、自动上料搅拌车进料口给料量是否合理
2. Whether the feeding amount at the inlet of the automatic feeding mixer is reasonable
我们很多项目使用手动料枪吸料,操作为了方便直接将料枪插入物料桶或者吨袋中,料枪吸料口被严实的物料压缩,强大的负压将满满的物料拉走,这对上料机伤害非常大,且非常容易堵塞管道。正确的方式是物料在吸料口和空气形成一定的气物混合比,在气流的推动下均匀流入上料机。这个时候我们需要将料枪设计带有补气功能。如果物料积压时间过长可能很硬,这个时候需要在料枪上装一个振荡器,敲碎结块的物料。
Many of our projects use manual material gun to suck materials. In order to facilitate the operation, the material gun is directly inserted into the material barrel or ton bag. The material suction port of the material gun is compressed by tight materials, and the strong negative pressure pulls away the full materials, which is very harmful to the feeding machine and is very easy to block the pipeline. The correct way is that the material forms a certain gas-material mixing ratio with the air at the suction port, and flows evenly into the feeder under the push of the air flow. At this time, we need to design the material gun with air replenishment function. If the material backlog is too long, it may be very hard. At this time, an oscillator needs to be installed on the material gun to break the caked materials.
