氣力輸送設(shè)備中的旋轉(zhuǎn)供料器葉片具有優(yōu)良的耐磨性能，鎖氣效果突出、卸料過程徹底干凈、整體結(jié)構(gòu)緊湊且嚴(yán)實。它采用彈性轉(zhuǎn)子設(shè)計，使得密封性能更為優(yōu)異，能夠穩(wěn)定保證物料的均勻喂送。其組成部分包括閥體、傳動軸、葉片以及減速器等關(guān)鍵部件。

　　The rotating feeder blades in pneumatic conveying equipment have excellent wear resistance, outstanding air locking effect, thoroughly clean unloading process, compact and tight overall structure. It adopts an elastic rotor design, which makes the sealing performance more excellent and can stably ensure the uniform feeding of materials. Its components include key parts such as valve body, transmission shaft, blades, and reducer.

　　減速電機(jī)作為動力源，帶動傳動軸與葉輪進(jìn)行轉(zhuǎn)動，進(jìn)而實現(xiàn)卸灰的操作目的。該設(shè)備運用了行星轉(zhuǎn)動的原理，讓輸入軸與輸出軸處于同一條軸線上，并且具備與電機(jī)直接連接成一體的獨特特性，正因如此，它的結(jié)構(gòu)十分緊湊、造型新穎且美觀大方，同時還具有體積小、重量輕的優(yōu)勢。

　　As a power source, the deceleration motor drives the transmission shaft and impeller to rotate, thereby achieving the purpose of ash unloading operation. This device utilizes the principle of planetary rotation, allowing the input shaft and output shaft to be on the same axis, and has the unique feature of being directly connected to the motor as a whole. Therefore, its structure is very compact, the shape is novel and beautiful, and it also has the advantages of small size and light weight.

　　旋轉(zhuǎn)供料器的密封性能表現(xiàn)出色，給料過程均勻且穩(wěn)定，卸料運行狀態(tài)平穩(wěn)，工作時產(chǎn)生的噪音小，出現(xiàn)故障的概率低，使用壽命較長，耐磨程度也很高。其中的軸承、齒箱等部件遠(yuǎn)離閥體，能夠有效避免受到高溫粉塵的不良影響，前后端蓋的密封效果良好，可以防止粉塵向外泄漏，這一設(shè)計有助于延長運動部件和潤滑系統(tǒng)的使用年限。

　　The sealing performance of the rotary feeder is excellent, the feeding process is uniform and stable, the unloading operation is smooth, the noise generated during operation is small, the probability of failure is low, the service life is long, and the wear resistance is also high. The bearings, gearboxes, and other components are located away from the valve body, effectively avoiding the adverse effects of high-temperature dust. The sealing effect of the front and rear end caps is good, which can prevent dust leakage outward. This design helps to extend the service life of moving parts and lubrication systems.

　　它的輸送能力較強(qiáng)，耐受沖擊的慣性力小，非常適合用于需要頻繁起動以及正反轉(zhuǎn)操作的場景。在吸收球的氣力輸送過程中，旋轉(zhuǎn)供料器是一個至關(guān)重要的設(shè)備，其主要的功能是對堆芯落球孔道中的吸收球顆粒進(jìn)行初始的流態(tài)化處理，從而形成氣固兩相流。由于旋轉(zhuǎn)供料器被設(shè)置在反應(yīng)堆壓力容器內(nèi)部，進(jìn)行維修操作存在諸多不便，所以它對于吸收球初始流態(tài)化的可靠性和穩(wěn)定性有著極高的要求。旋轉(zhuǎn)供料器的結(jié)構(gòu)是影響其工作性能的一個重要因素，在 10MW 高溫氣冷實驗堆的吸收球停堆系統(tǒng)中，所使用的是誘導(dǎo)式旋轉(zhuǎn)供料器，其氣力輸送方式為吸送式，并且搭建了以常溫常壓空氣作為氣源的負(fù)壓吸收方式。相關(guān)的試驗結(jié)果表明，流化管式旋轉(zhuǎn)供料器在吸收球的流態(tài)化順暢性以及重啟可靠性方面，都要優(yōu)于另外兩種旋轉(zhuǎn)供料器，不過，關(guān)于流化管式旋轉(zhuǎn)供料器的吸收球輸送速率以及壓降隨著空氣流速變化的規(guī)律，目前尚未有相關(guān)的報道。

　　It has strong conveying capacity and low inertia force to withstand impact, making it very suitable for scenarios that require frequent starting and forward/reverse operations. In the pneumatic conveying process of absorbing balls, the rotary feeder is a crucial equipment, whose main function is to perform initial fluidization treatment on the absorbing ball particles in the core falling ball hole, thereby forming gas-solid two-phase flow. Due to the fact that the rotary feeder is located inside the reactor pressure vessel, there are many inconveniences in maintenance operations, so it has extremely high requirements for the reliability and stability of the initial fluidization of the absorption ball. The structure of the rotary feeder is an important factor affecting its performance. In the absorption ball shutdown system of the 10MW high-temperature gas cooled experimental reactor, an induced rotary feeder is used, and its pneumatic conveying method is suction type. A negative pressure absorption method using normal temperature and pressure air as the gas source is also established. The relevant experimental results show that the fluidized tube rotary feeder is superior to the other two types of rotary feeders in terms of the smoothness of fluidization and restart reliability of the absorption balls. However, there are currently no relevant reports on the law of the absorption ball conveying rate and pressure drop of the fluidized tube rotary feeder changing with the air flow velocity.
