料倉下料口堵料的處理方法:
The treatment method for blockage of the discharge port of the silo:
料倉下料口堵料是一個常見的問題,可能會由多種原因造成,如物料的流動性差、含水量高、粘性大等。解決這一問題的方法有很多,以下是一些有效的處理策略:
Blockage at the discharge port of the silo is a common problem that can be caused by various reasons, such as poor flowability, high moisture content, and high viscosity of the material. There are many ways to solve this problem, and here are some effective strategies:
1. 使用料倉滑板
1. Use the silo skateboard
料倉滑板具有高耐磨、耐腐蝕、耐沖擊、自潤滑等特點,可以制作裝煤、沙子、土、水泥、石灰、礦粉、鹽、谷物類粉狀材料的料斗、料倉、滑槽的襯里。由于它具有優(yōu)良的耐摩性、自潤滑性及不粘性,能夠有效防止粉狀材料對儲運設備的粘附現(xiàn)象,從而解決料倉下料口堵料的問題458。
The silo sliding plate has the characteristics of high wear resistance, corrosion resistance, impact resistance, and self-lubricating. It can be used to make the lining of hoppers, silos, and chutes for coal, sand, soil, cement, lime, mineral powder, salt, and grain powder materials. Due to its excellent wear resistance, self-lubricating properties, and non adhesiveness, it can effectively prevent the adhesion of powdered materials to storage and transportation equipment, thereby solving the problem of material blockage at the discharge port of the silo.
2. 改進料倉結構
2. Improve the structure of the silo
在料倉制作之初,可以從料倉結構、改流體及振動與充氣流化等方面采取措施來防止起拱與閉塞。例如,可以采用偏向卸料口的設計,具有鉛垂壁面或非對稱形壁面,以減少其鉛垂壓力,起著消除拱腳的作用;或者采用曲線料斗,呈指數(shù)曲線狀的料斗不易起拱。
At the beginning of silo production, measures can be taken to prevent arching and blockage from aspects such as silo structure, fluid modification, vibration, and inflation fluidization. For example, a design that leans towards the discharge port can be adopted, with vertical or asymmetric walls to reduce its vertical pressure and eliminate arch feet; Alternatively, a curved hopper can be used, which has an exponential curve shape and is less prone to arching.
3. 采用防堵設備
3. Adopt anti blocking equipment
可以采用空氣炮、振動器等設備來防止和解決物料堵塞問題。這些設備可以通過敲擊、噴射或振動的方式來清除粘結在下料口的物料,從而避免堵料的發(fā)生。
Equipment such as air cannons and vibrators can be used to prevent and solve material blockage problems. These devices can remove materials stuck to the discharge port by tapping, spraying, or vibrating, thereby avoiding material blockage.
4. 加裝輔助加熱裝置
4. Install auxiliary heating devices
如果物料在下料口堵塞是因為溫度過低導致的結塊,可以在放料口加裝輔助加熱裝置,如伴熱帶、伴熱管等,以保持物料的流動性和防止結塊。
If the material is blocked at the discharge port due to low temperature causing clumping, auxiliary heating devices such as heat tracing belts, heat tracing pipes, etc. can be installed at the discharge port to maintain the fluidity of the material and prevent clumping.
5. 改進放料裝置
5. Improve the feeding device
如果是因為放料裝置設計不合理導致的堵料,可以考慮改進放料裝置。例如,可以改用上展式放料閥,或用轉料管采用壓力轉料或真空轉料的方式。
If the blockage is caused by an unreasonable design of the discharge device, it can be considered to improve the discharge device. For example, an upward spreading discharge valve can be used, or a transfer tube can be used for pressure or vacuum transfer.
6. 使用防堵系統(tǒng)及方法
6. Use anti blocking system and methods
可以采用下料口清理防堵系統(tǒng)及方法,該系統(tǒng)包括振動傳感器、工控機和輔助下料機構。振動傳感器用于實時監(jiān)測下料口的振動參數(shù),工控機用于接收振動參數(shù)并控制輔助下料機構動作,輔助下料機構用于在工控機的驅(qū)動下清理下料口處的粘接物料。
A discharge port cleaning and anti blocking system and method can be used, which includes vibration sensors, industrial computers, and auxiliary discharge mechanisms. The vibration sensor is used to monitor the vibration parameters of the feeding port in real time, and the industrial computer is used to receive the vibration parameters and control the action of the auxiliary feeding mechanism. The auxiliary feeding mechanism is used to clean the adhesive material at the feeding port under the drive of the industrial computer.
綜上所述,處理料倉下料口堵料問題需要根據(jù)具體情況選擇合適的方法。在實際操作中,可能需要結合多種方法來達到最佳效果。
In summary, the problem of material blockage at the discharge port of the silo needs to be addressed by selecting appropriate methods based on specific circumstances. In practical operation, it may be necessary to combine multiple methods to achieve the best results.
