LQY-80型產品介紹及主要技術性能

（一）產品介紹

1、該產品的結構為可靠穩固

我廠是國內雙滾筒移動間歇式瀝青混凝土拌和設備的生產商家，已有二十多年的專業生產歷史。九十年代初我廠就創造性地采用提料裝置、烘干滾筒和攪拌器聯成一體并分別固定在同一拖掛底盤上，具有分體式移動結構形式，把拖掛式移動功能成功地應用到強制式瀝青攪拌設備上。在作業過程中，兩個具有獨立提料的烘干系統能按設定的時間間隔交替循環地向設在出料口下方的攪拌器供給熱礦料，這種結構形式可以增加熱礦料供給又能更大限度地發揮攪拌器的效率。強制式系列產品分別于1997年、2002年獲得國家專利局授予的《實用新型專利證書》，2010年獲得名稱“一種新型瀝青混凝土拌和機”（ ZL 2010 2 0287777.）一種用于提升和儲存瀝青混凝土成品料的裝置（ZL 2010 2 0287745.8），這種獨特的組合結構受國家專利保護。

2、該產品得到權威機構的檢測和筑機專家的鑒定

福建省技術監督局所屬的檢驗機構對強制式系列產品進行過多次嚴格的質量檢測，檢測數據表明，強制式系列產品的各項技術性能指標均達到國家標準及行業標準。

經國內有影響力的筑機專家指導和建議，我廠部分強制式產品于2002年12月通過了由福建省交通廳組織的產品技術鑒定，鑒定委員會的筑機專家一致認為：強制式系列產品的結構型式為質量穩定，提交鑒定的產品各項技術性能指標均達到國家標準及行業標準。

2003年強制式產品榮獲福建省人民政府頒發的優秀新產品獎。

2004年強制式產品榮獲福建省人民政府頒發的科學技術進步獎。

2007年泉筑產品及其商標榮獲福建省人民政府頒發的“福建省名牌產品”稱號。

3、該系列產品經過市場的長期檢驗

自七十年代末研制開發出雙滾筒瀝青混合料拌和機以來，至今已有幾千多臺不同規格型號的拌和機產品服務于全國各地。并因此積累了豐富的生產經驗、市場服務經驗和開發研制經驗。LQY-80型瀝青混凝土攪拌設備的核心部件即雙臥軸強制式攪拌器已有800多臺在工地上使用，成為瀝青攪拌設備的穩定供應商。

4、該產品主要部件經過精心的設計

短小高效的全新干燥滾筒結構。根據該機型的工作特點，改進確定了比較合理的葉片結構和安裝角度，烘干時能過使礦料在滾筒內產生提升、推翻和軸向竄動，形成較強烈和比較均勻密集的截面料簾，強化了燃燒火焰和礦料之間的輻射對流換熱，提高了滾筒的熱效率。經反復試驗而精心設計的卸料葉片能過在較短的時間內完成過料。

穩固的攪拌器結構形式。根據不同混合料的特點，攪拌器采用雙臥軸攪拌臂為雙螺旋布置的結構形式，軸端采用浮動油封裝置，使之能滿足攪拌穩定土、水泥和瀝青的要求。

牽引系統的轉向機構采用符合部頒標準的轉盤式結構，使拖掛移場安全可靠。

5、該產品均采用精良的材料和元件

烘干滾筒采用耐熱、耐沖刷和抗變形的16Mn鋼板材料制作。

大梁采用18號重型槽鋼制造而成，并采用液壓可調整支撐腳，使整臺設備使用時穩固牢靠。

控制系統的核心部件PLC采用日本三菱產品。其他電器如接觸器、繼電器和形程開關采用西門子產品。

燃燒爐爐膛內采用套裝成型耐火磚砌制，耐火磚以高性能指標的原材料采用大型鋼模制造而成，具備耐久的使用性能。

6、電氣控制及保護方面

設計了先進的計量控制系統。為了保證攪拌設備能夠拌出符合技術指標的成品料，計量系統通過在多個工位安裝高精度的電子傳感器，采用二次微量補料功能，實現對礦料、粉料和瀝青的精確配比，能夠確保瀝青、粉料計量誤差在±0.5％，礦料計量誤差在±1.0％之內。

經過先進的程序設計和互鎖原理，可有效預防攪拌缸重鍋、瀝青空筒或溢料現象，可有效保證成品料的質量。并設有未過料報警功能，以提醒操作人員及時關閉燃燒裝置。

(1) Product Introduction
The structure of this product is reliable and stable.
1.Our factory is a producer of domestic double-drum mobile intermittent asphalt concrete mixing equipment. We have a professional production history of over twenty years. In the early 1990s, our factory innovatively adopted a design where the feeding device, drying drum and mixer were integrated and fixed on the same trailer chassis, featuring a split-type mobile structure. This design successfully applied the mobile function of the trailer to the forced asphalt concrete mixing equipment. During operation, two independent feeding drying systems can supply hot aggregate to the mixer located below the discharge port at set time intervals in an alternating and cyclic manner. This structure can increase the supply of hot aggregate and maximize the efficiency of the mixer. The forced series products were granted the "Utility Model Patent Certificate" by the National Patent Office in 1997 and 2002 respectively, and in 2010, we obtained the name "A New Type of Asphalt Concrete Mixing Machine" (ZL 2010 2 0287777.) and a device for lifting and storing asphalt concrete finished products (ZL 2010 2 0287745.8). This unique combined structure is protected by national patents.
2. This product has been tested by authoritative institutions and appraised by experts in construction machinery.
The inspection institutions affiliated to the Technical Supervision Bureau of Fujian Province have conducted numerous rigorous quality inspections on the series of products of the "forced type". The inspection data indicate that all technical performance indicators of the series of products of the "forced type" have met the national and industry standards.
After receiving guidance and suggestions from influential domestic experts in construction machinery, some of our factory's forced-type products passed the product technical appraisal organized by the Fujian Provincial Department of Transportation in December 2002. The experts in construction machinery of the appraisal committee unanimously believed that the structural type of the forced-type series products is stable in quality, and all the technical performance indicators of the submitted products have reached the national and industry standards.
In 2003, the product was awarded the Excellent New Product Award by the Fujian Provincial People's Government for its outstanding performance.
In 2004, the product was awarded the Science and Technology Progress Award by the Fujian Provincial People's Government for its outstanding performance.
In 2007, Quzhu products and its trademarks were awarded the title of "Fujian Province Famous Brand Products" by the Fujian Provincial People's Government.
3. This series of products have been tested in the market for a long time.
Since the development of the double drum asphalt mixture mixing machine in the late 1970s, more than 6,000 sets of different specifications and models of such machines have been put into service across the country. As a result, rich production experience, market service experience and development and research experience have been accumulated. The core component of the LQY-80 asphalt concrete mixing equipment, namely the double horizontal shaft forced mixing device, has been used on construction sites by more than 800 sets, making it a stable supplier of asphalt mixing equipment.
4. The main components of this product have been meticulously designed.
A compact and efficient new type of drying drum structure. According to the working characteristics of this model, the reasonable blade structure and installation angle have been determined after improvement. During the drying process, the ore materials can be lifted, overturned and axially displaced within the drum, forming a relatively strong and relatively uniform dense fabric curtain. This enhances the radiant and convective heat exchange between the combustion flame and the ore materials, improving the thermal efficiency of the drum. The discharge blades designed through repeated experiments and careful consideration can complete the material discharge within a relatively short time.
Stable mixer structure form. According to the characteristics of different mixtures, the mixer adopts a structure form with double horizontal shafts and double helical blades arranged in a double-screw layout. The shaft ends are equipped with floating oil seals to meet the requirements for mixing stable soil, cement and asphalt.
The steering mechanism of the traction system adopts the disc-type structure in accordance with the national standards, ensuring the safety and reliability of the trailer towing and relocation.
5. This product is made with high-quality materials and components.
The drying drum is made of 16Mn steel plates which are heat-resistant, erosion-resistant and deformation-resistant.
The main beam is made of No. 18 heavy-duty channel steel and is equipped with hydraulic adjustable support feet, ensuring the stability and reliability of the entire equipment during use.
The core component of the control system, PLC, adopts the product of Mitsubishi of Japan. Other electrical appliances such as contactors, relays and limit switches adopt the products of Siemens.
The combustion furnace furnace chamber is constructed by installing and molding refractory bricks. The refractory bricks are manufactured using large steel molds with high-performance raw materials, and they possess durable usage performance.
6. Electrical Control and Protection Aspects
An advanced metering control system has been designed. To ensure that the mixing equipment can produce finished materials that meet the technical indicators, the metering system installs high-precision electronic sensors at multiple stations and adopts the secondary micro-supplement function to achieve precise proportioning of mineral materials, powder materials and asphalt. It can ensure that the metering error of asphalt and powder materials is within ±0.5%, and the metering error of mineral materials is within ±1.0%.
Through advanced program design and interlocking principle, it can effectively prevent the phenomena of heavy load in the mixing cylinder, empty asphalt cylinder or overflow of materials, and can effectively ensure the quality of the finished materials. Moreover, it is equipped with an alarm function for unloading failure to remind the operators to promptly shut down the combustion device.
