Gansu "Waste-free city" construction forward, and solid waste brick making has become the preferred solution for solid waste treatment

On August 1, 2023, the solid waste treatment production line designed and manufactured by Qunfeng Machinery, which provides full installation and training services, was officially put into use in Hexi, Gansu Province. This solid waste treatment production line will participate in the reconstruction of old urban areas and the construction of roads and bridges in the Hexi area of Gansu Province. Through solid waste brick making, it will achieve the dual goals of resource utilization and environmental protection, and will effectively promote the construction of a "zero-waste city" in Gansu Province.

For a long time, promoting the harmless treatment of solid waste has been a difficult problem in the construction of "waste-free cities" in Gansu Province. According to the "Lanzhou Second National Pollution Source Census Bulletin" issued by Lanzhou City in 2020, due to the renovation of old urban areas and the limitations of the original production structure, 3.19 million tons of industrial solid waste and 160,000 tons of industrial solid waste were generated in the provincial capital Lanzhou alone. tons of hazardous waste.

Traditional solid waste treatment methods mainly include incineration, landfill, composting, etc. These methods not only waste resources, but also cause many associated problems, such as soil pollution, water pollution, air pollution, etc. In order to solve this problem and change the thinking of urban governance, the State Council issued the "Pilot Work Plan for the Construction of Zero Waste City" in 2018, hoping to continue to promote solid waste development under the guidance of the new development concept of "innovation, coordination, green, openness and sharing". Utilize resources and minimize the amount of landfill. Solid waste brick making is a building material made by mixing solid waste with cement, lime, coal ash and other raw materials, and then molded by high-temperature autoclaving. It not only solves the problem of waste disposal, but also achieves resource utilization and environmental protection. It is the preferred solution for solid waste treatment. In this context, a state-owned enterprise in the Hexi area of Gansu Province decided to introduce a solid waste treatment production line to participate in the construction of a "Waste-free city" in Gansu Province.

Layers of screening to stand out

The company is a state-owned enterprise with strength and influence in Gansu Province. It has been committed to urban infrastructure construction for many years and actively participated in municipal engineering, road and bridge construction and real estate development projects in Gansu Province. In 2020, the company started the bidding work for the solid waste production line. In contact with a number of domestic and international equipment suppliers, and analyzing and comparing the process flow, construction plan, equipment selection and economic strength, etc. Among them, Qunfeng stood out by virtue of its highly customized solutions, strong soft and hard power, and rich service experience in Northwest China, and became the equipment supplier of this project.

Intimate customized service to win customer affirmation

In order to better meet the actual production needs of customers, Qunfeng always insists on providing customized services for each customer, thinking about what customers think and solving customers' worries. When formulating the process plan, Qunfeng’s technical engineers optimized and customized the motor and hydraulic components in the plan in view of the hot environment in the northwest region, so as to increase the heat dissipation capacity and reduce the heat-up time, making the entire production line more suitable for Northwest production harsh environment.

After the start of the project in 2023, in order to ensure that the project can be completed with high quality and a short construction period, Qunfeng has organized staff to station in Gansu Province non-stop to carry out construction. During the installation process, Qunfeng's technical engineers did not forget to teach customers the experience of using the equipment. Qunfeng's professional and careful technical installation services have won high recognition from customers.

Smooth delivery! Qunfeng Intelligent Technology made a stunning appearance

After dozens of days of installation, the solid waste treatment production line was finally successfully delivered on August 1. The production line takes Qunfeng Concrete Products Forming Machine as the core, and its vibration system adopts a high-efficiency servo vibration system with high speed and fast action response. Taking standard bricks as an example, the forming speed of each plate is 3 to 4 seconds higher than that of similar models in the market, which is effective Increased productivity. It can adapt to the recycling of construction waste recycled aggregate, fly ash, slag, coal gangue, coal rock, tailings and other solid waste materials to make bricks, and because of the use of Qunfeng's brick machine mold and fabric system, the pressed masonry The blocks are denser and brighter than conventional blocks, which has won the affirmation of customers.

In addition, the production line is also equipped with a car maintenance system, which has the advantages of strong load capacity, fast transfer speed, stability and reliability, etc. It can transfer the newly formed wet concrete products of the production line to the maintenance area, and then transfer the cured concrete products Go to the packing area for palletizing and packing. This process does not require excessive manual intervention, which effectively simplifies staffing and reduces labor costs.

It is foreseeable that after the successful commissioning of this solid waste treatment production line with a large single-machine capacity in China, it will help the customer contribute more to the goal of carbon neutrality in Gansu Province. Qunfeng will also continue to uphold a rigorous service attitude and high-efficiency service level to bring more caring, worry-free and assured smart technology experience to global customers.
