自動上料攪拌車常見的問題是堵料問題,該如何避免這一情況呢?下面為大家介紹一下。
The common problem of automatic feeding mixer is material blockage. How to avoid this situation? Let's introduce it to you.
1、上下料時間參數不合理
1. Unreasonable loading and unloading time parameters
自動上料機因料倉內無法加裝料位機,所以行業基本都有時間控制。如何設置時間參數,上下料時間設置其實很簡單,在初次使用時,先設置一個小的時候,然后根據每次吸料位置慢慢加,當達到料位達到吸料口的時間,再減去一秒便是合理時間。放料時間是確保放完料再加一秒。這樣做有兩個好處:一是料位太高對濾芯傷害特別大,我們有些客戶一個濾芯能用兩年有些用半年也是這個原因。二是每次料都能放干凈,下料閥在關閉的時候不會出現帶料關閥,帶料關閥對沒分鐘開關五六次的這種頻繁工作的密封圈傷害特別大。
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、自動上料攪拌車進料口給料量是否合理
2. Whether the feeding amount at the inlet of the automatic feeding mixer is reasonable
我們很多項目使用手動料槍吸料,操作為了方便直接將料槍插入物料桶或者噸袋中,料槍吸料口被嚴實的物料壓縮,強大的負壓將滿滿的物料拉走,這對上料機傷害非常大,且非常容易堵塞管道。正確的方式是物料在吸料口和空氣形成一定的氣物混合比,在氣流的推動下均勻流入上料機。這個時候我們需要將料槍設計帶有補氣功能。如果物料積壓時間過長可能很硬,這個時候需要在料槍上裝一個振蕩器,敲碎結塊的物料。
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.
