(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.
