在鑄造行業(yè)領(lǐng)域，粉煤灰輸送系統(tǒng)主要采用稀相和濃相兩種基本輸送模式，同時包含吸送和壓送兩種輸送方式。具體選用哪種氣力輸送類型需要綜合考慮被輸送物料的物理特性和生產(chǎn)工藝的具體技術(shù)要求。

　　In the field of casting industry, the fly ash conveying system mainly adopts two basic conveying modes: dilute phase and dense phase, and includes both suction and pressure conveying modes. The specific selection of pneumatic conveying type requires comprehensive consideration of the physical characteristics of the conveyed material and the specific technical requirements of the production process.

　　針對粉狀物料的專業(yè)輸送系統(tǒng)通常采用流態(tài)化發(fā)送罐進行連續(xù)輸送，可選擇上引式或下引式兩種不同工藝方案。完整的粉料輸送系統(tǒng)包含多個關(guān)鍵組件，主要包括倒料裝置、除塵設(shè)備、流態(tài)化發(fā)送罐、增壓設(shè)備、耐磨管道系統(tǒng)、分流裝置、卸料機構(gòu)以及尾氣處理系統(tǒng)等。這類輸送系統(tǒng)主要服務(wù)于機械化造型生產(chǎn)線的砂處理工序，能夠為新砂、舊砂、煤粉以及黏土粉等多種物料提供精確的輸送服務(wù)。所有物料都需要經(jīng)過電子稱重系統(tǒng)的精確計量，按照預設(shè)配方比例投入混砂機進行混合處理。典型的砂處理車間通常配置多臺混砂設(shè)備，需要設(shè)置2到10個不同的卸料點位，系統(tǒng)輸送距離一般在20至100米范圍內(nèi)，每小時輸送能力可達6到10噸。

　　Professional conveying systems for powdered materials typically use fluidized bed conveying tanks for continuous conveying, with two different process options available: upward or downward. A complete powder conveying system consists of multiple key components, mainly including a feeding device, dust removal equipment, fluidized sending tank, pressurization equipment, wear-resistant pipeline system, diversion device, unloading mechanism, and exhaust gas treatment system. This type of conveying system mainly serves the sand processing process of mechanized molding production lines, and can provide precise conveying services for various materials such as new sand, old sand, coal powder, and clay powder. All materials need to be accurately measured by an electronic weighing system and mixed in the sand mixer according to the preset formula ratio. A typical sand processing workshop is usually equipped with multiple sand mixing equipment, requiring the setting of 2 to 10 different unloading points. The system conveying distance is generally within the range of 20 to 100 meters, and the hourly conveying capacity can reach 6 to 10 tons.

　　粒狀物料輸送系統(tǒng)部分：

　　2. 對于鑄造行業(yè)中的各類粒狀物料，包括干濕石英砂、再生樹脂砂、再生水玻璃砂以及特殊鑄造用砂等，都可以采用正壓濃相氣力輸送技術(shù)。這類系統(tǒng)可以采用單發(fā)送罐間歇式輸送方案，也可以采用雙罐并聯(lián)的配置方式，通過交替進行輸送和裝料作業(yè)來實現(xiàn)準連續(xù)化輸送。系統(tǒng)特別適合處理各種金屬磨料，如鐵丸、鋼丸等特殊物料。

　　For various granular materials in the casting industry, including dry and wet quartz sand, recycled resin sand, recycled water glass sand, and special casting sand, positive pressure dense phase pneumatic conveying technology can be used. This type of system can adopt a single tank intermittent conveying scheme or a dual tank parallel configuration, achieving quasi continuous conveying by alternating conveying and loading operations. The system is particularly suitable for processing various metal abrasives, such as iron balls, steel balls, and other special materials.

　　系統(tǒng)應(yīng)用特性說明部分：

　　System application feature description section:

　　粉煤灰輸送機采用密相中壓氣力輸送技術(shù)，特別適合輸送那些不易破碎的顆粒狀和粉狀物料。該技術(shù)已經(jīng)在鑄造工業(yè)、化學工業(yè)以及糧食加工等多個行業(yè)領(lǐng)域得到廣泛應(yīng)用，展現(xiàn)出卓越的適應(yīng)性和可靠性。系統(tǒng)集成時必須充分考慮水平方向可能達到上百米的輸送距離，以及垂直方向需要跨越多個樓層的特殊要求。由于整個工藝流程可能涉及十幾個不同的設(shè)備工位，因此系統(tǒng)集成能力成為衡量粉體輸送系統(tǒng)設(shè)計水平的關(guān)鍵指標。優(yōu)秀的系統(tǒng)集成商需要具備豐富的工程經(jīng)驗，能夠合理規(guī)劃系統(tǒng)布局，優(yōu)化管路設(shè)計，精確控制物料流向，并實現(xiàn)精準的定量控制。國內(nèi)電力行業(yè)等專業(yè)領(lǐng)域已經(jīng)積累了相當豐富的系統(tǒng)集成經(jīng)驗，能夠提供成熟可靠的低壓連續(xù)輸送解決方案。

　　The fly ash conveyor adopts dense phase medium pressure pneumatic conveying technology, which is particularly suitable for conveying granular and powdery materials that are not easily broken. This technology has been widely applied in various industries such as foundry, chemical, and grain processing, demonstrating excellent adaptability and reliability. When integrating the system, it is necessary to fully consider the transportation distance that may reach hundreds of meters in the horizontal direction, as well as the special requirements of crossing multiple floors in the vertical direction. Due to the fact that the entire process may involve over a dozen different equipment workstations, system integration capability has become a key indicator for measuring the design level of powder conveying systems. Excellent system integrators need to have rich engineering experience, be able to plan system layout reasonably, optimize pipeline design, accurately control material flow, and achieve precise quantitative control. The domestic power industry and other professional fields have accumulated considerable experience in system integration, which can provide mature and reliable low-voltage continuous transmission solutions.
