旋轉(zhuǎn)供料器，常被稱為關(guān)風(fēng)機(jī)、卸料器、旋轉(zhuǎn)給料閥、旋轉(zhuǎn)卸料閥、旋轉(zhuǎn)閥等，是散狀物料輸送過(guò)程中的關(guān)鍵設(shè)備。憑借運(yùn)行可靠、成本適宜等特點(diǎn)，被廣泛應(yīng)用于糧食加工、化工原料、塑料冶金、能源礦業(yè)、建材水泥、碼頭等多個(gè)領(lǐng)域。在啤酒生產(chǎn)的麥芽車間、釀造車間中，輸送大麥、麥芽等物料時(shí)，也普遍采用旋轉(zhuǎn)供料器完成物料轉(zhuǎn)運(yùn)。

　　Rotary feeders, commonly known as shut-off fans, unloaders, rotary feed valves, rotary discharge valves, rotary valves, etc., are key equipment in the process of conveying bulk materials. Due to its reliable operation and suitable cost, it is widely used in various fields such as grain processing, chemical raw materials, plastic metallurgy, energy mining, building materials and cement, docks, etc. In the malt and brewing workshops of beer production, rotary feeders are commonly used to transport materials such as barley and malt.

　　旋轉(zhuǎn)供料器主要由主閥（包含殼體、端蓋、葉輪、密封結(jié)構(gòu)等部件）、電機(jī)減速機(jī)、防護(hù)裝置（如鏈輪、鏈輪罩等）以及排氣口等部分構(gòu)成。其配套組件包括抽氣室、加速室、防卡進(jìn)料器等。這類設(shè)備又稱星型給料器、旋轉(zhuǎn)給料機(jī)、鎖氣器等，其核心結(jié)構(gòu)與工作原理是通過(guò)帶有多個(gè)葉片的轉(zhuǎn)子在圓形機(jī)殼內(nèi)轉(zhuǎn)動(dòng)，將上部料斗中的物料通過(guò)葉片間的空隙旋轉(zhuǎn)運(yùn)送至下部排出。在風(fēng)力輸送系統(tǒng)（包括壓送式和吸送式）中，旋轉(zhuǎn)供料器不僅要完成卸料功能，還需避免高壓氣體通過(guò)供料器泄漏到上部料倉(cāng)，防止影響物料下落。因此，它是氣力輸送系統(tǒng)中的重要組成部分，既能向輸料管中均勻、連續(xù)地定量供料，實(shí)現(xiàn)物料輸送；又能在系統(tǒng)的分離收塵部分發(fā)揮卸料器的作用。

　　The rotary feeder mainly consists of the main valve (including housing, end cover, impeller, sealing structure, etc.), motor reducer, protective device (such as sprocket, sprocket cover, etc.), and exhaust port. Its supporting components include an exhaust chamber, an acceleration chamber, an anti jam feeder, etc. This type of equipment is also known as star feeders, rotary feeders, air locks, etc. Its core structure and working principle are to rotate a rotor with multiple blades inside a circular casing, and transport the material in the upper hopper through the gaps between the blades to the lower part for discharge. In wind conveying systems (including pressure feeding and suction feeding), the rotating feeder not only needs to complete the unloading function, but also needs to prevent high-pressure gas from leaking into the upper material bin through the feeder to prevent it from affecting the falling of materials. Therefore, it is an important component of the pneumatic conveying system, which can evenly and continuously supply materials to the conveying pipe in a quantitative manner, achieving material conveying; It can also play the role of an unloader in the separation and dust collection part of the system.

　　主要機(jī)型特性

　　Main model characteristics

　　防卡型：采用防卡進(jìn)料結(jié)構(gòu)設(shè)計(jì)，能根據(jù)不同物料特性調(diào)整間隙，必要時(shí)采用偏置式機(jī)體、鑲片式轉(zhuǎn)子或 V 型轉(zhuǎn)子，具備防卡堵和減少物料破碎的功能，可通過(guò)多種防卡設(shè)計(jì)組合提升適用性。

　　Anti jamming type: Adopting an anti jamming feeding structure design, the gap can be adjusted according to the characteristics of different materials. If necessary, a biased body, embedded rotor or V-shaped rotor can be used, which has the functions of anti jamming and reducing material breakage. Multiple anti jamming design combinations can be used to improve applicability.

　　耐壓型：配備封閉型轉(zhuǎn)子，廣泛應(yīng)用于吸送式、壓送式氣力輸送系統(tǒng)，能有效降低漏氣量，保障氣力輸送系統(tǒng)的穩(wěn)定運(yùn)行，尤其適用于對(duì)氣壓密封性要求較高的場(chǎng)景。

　　Pressure resistant type: equipped with a closed rotor, widely used in suction and compression pneumatic conveying systems, can effectively reduce air leakage and ensure stable operation of the pneumatic conveying system, especially suitable for scenarios with high requirements for air pressure sealing.

　　耐溫型：采用外裝式結(jié)構(gòu)設(shè)計(jì)，將運(yùn)轉(zhuǎn)部件與接觸物料的箱體部分分離，使軸承和油封系統(tǒng)免受高溫影響，確保設(shè)備正常工作。該機(jī)型還特別適合輸送金屬粉末和超細(xì)粉料，可避免這類物料侵入軸承和油封系統(tǒng)造成損壞。

　　Temperature resistant type: Adopting an external structural design, the operating components are separated from the box body that comes into contact with the material, which protects the bearing and oil seal system from high temperatures and ensures the normal operation of the equipment. This model is particularly suitable for conveying metal powder and ultrafine powder materials, which can prevent such materials from entering the bearing and oil seal system and causing damage.

　　防粘型：通過(guò)特殊結(jié)構(gòu)設(shè)計(jì)，能穩(wěn)定輸送易粘連、易結(jié)塊的物料，解決傳統(tǒng)設(shè)備在處理這類物料時(shí)出現(xiàn)的堵塞問(wèn)題。

　　Anti sticking type: Through special structural design, it can stably transport materials that are prone to adhesion and clumping, solving the problem of blockage that traditional equipment encounters when handling such materials.

　　中高壓旋轉(zhuǎn)供料器包含主機(jī)、連接側(cè)板、鏈輪、鏈條、鏈罩等部件。接料器與供料器是使物料與空氣混合并送入輸料管的設(shè)備，是風(fēng)力輸送裝置的關(guān)鍵環(huán)節(jié)。接料器的結(jié)構(gòu)合理性，直接影響整個(gè)風(fēng)力輸送裝置的輸送量、運(yùn)行穩(wěn)定性及能耗高低。因此，根據(jù)裝置的不同工作條件，正確設(shè)計(jì)和選用合適的接料器，是提升風(fēng)力輸送效果的重要舉措。

　　The medium and high pressure rotary feeder includes components such as the main engine, connecting side plates, chain wheels, chains, and chain covers. The feeder and receiving device are equipment that mix materials with air and feed them into the conveying pipe, and are key components of the wind powered conveying system. The rationality of the structure of the feeder directly affects the conveying capacity, operational stability, and energy consumption of the entire wind conveying device. Therefore, designing and selecting appropriate feeders according to the different working conditions of the device is an important measure to improve the effectiveness of wind conveying.
