The waste tire refining equipment has been developed to this day. After many technical updates and iterations, the process technology is mature and the equipment performance is stable. According to different processes, waste tire refining equipment can be divided into two types: batch type and continuous type oil refining equipment. Next, relying on years of experience in equipment R&D and manufacturing, Henan Dongying Company will introduce in detail the differences between continuous and batch waste tire refining equipment, as well as the differences between continuous tire refining equipment and batch tire refining equipment. What are the main differences.

Continuous vs intermittent waste tire refining equipment

The continuous waste tire refining equipment realizes continuous operation under the premise of safety and environmental protection. One furnace of one furnace of tire rubber powder can be continuously fed from the feed port, and the slag can be continuously discharged from the discharge port at the other end. There is no need to open the furnace door during production and operation. , fully airtight operation.

The intermittent waste tire refining equipment adopts open feeding and discharging. After the refining is completed, the equipment needs to be shut down to cool down, then the furnace door is opened to discharge slag and steel wire, and then start to load the next batch of tires, and then start to ignite and refine. It takes several hours from shutdown to the next refinery start-up, and continuous operation cannot be achieved.

The continuous waste tire refining equipment has a daily processing capacity of 15-50 tons per machine, with large processing capacity and high production efficiency.

Continuous waste tire refining equipment

The daily processing capacity of the intermittent waste tire refining equipment is 1-20 tons per day, the processing capacity is slightly smaller, and the operating efficiency is slightly lower.

The continuous waste tire refining equipment adopts an automatic fully-sealed feeding and slag discharge system, which allows re-feeding or slag discharge at a high temperature of more than 200 degrees, which greatly saves time and fuel costs between each two furnaces, and can save 20% of operating costs , In addition, the combustible gas produced by cracking can be 100% utilized, saving 70% of fuel.

Intermittent waste tire refining equipment

The intermittent waste tire refining equipment needs to meet the needs of secondary feeding or slag removal or steel wire drawing. The temperature of the main furnace must be cooled to below 60 degrees, and the cooling time of a single furnace needs 2-3 hours. The heat energy and time between the two furnaces The utilization rate is low and the operating cost is high; in addition, due to the intermittent production, the combustible gas cannot be continuously produced, so the equipment needs additional fuel consumption, and the combustible gas produced by cracking cannot be completely recycled.

The oil yield of continuous waste tire refining equipment is 45-50%, the quality is good, the density is generally around 0.89-0.91, the steel wire is drawn out in advance before entering the furnace, without heating, the market price is high, and the economic benefit is good.

Waste tire refining and its products

The oil yield of intermittent waste tire refining equipment is 40-45%, the quality is good, the density is around 0.91-0.93, and the steel wire needs to be heated at high temperature before it can be pulled out.

The continuous waste tire refining equipment adopts PLC intelligent control, which requires less labor, 1-2 people for a single production line, and low labor intensity.

Intermittent waste tire refining equipment requires manual or automatic feeder feeding, manual pulling out of steel wire, semi-automatic production and operation, a single production line requires 3-4 people, and there are more staffing requirements.

The continuous waste tire refining equipment conforms to the development direction of pyrolysis technology airtightness, continuous, automation, environmental protection and intelligence in the "Guiding Opinions on Comprehensive Utilization of Waste Tires" and "Access Conditions for Comprehensive Utilization of Waste Tires Industry", in line with the national The long-term development direction belongs to the development projects encouraged by the state.

The intermittent waste tire refining equipment is also in line with national policy requirements and environmental protection requirements, but in the long run, because of the need to open the furnace door when feeding waste steel wire and the intermittent production method, there will be replacements in the equipment update and iteration process. possible.

Automatic high-temperature closed feeding system for continuous waste tire refining equipment, 30 Feeding in minutes saves labor.

Comparison of waste tire refining feed methods

Manual or simple hydraulic feeding of intermittent waste tire refining equipment takes 1-2 hours, which is a waste of labor.

The continuous waste tire refining equipment is high-temperature sealed slag discharge, which is safe and environmentally friendly, and the slag discharge time is short. During the transmission process, the carbon black is cooled by water circulation and can be packed directly after reaching the slag bin.

The intermittent waste tire refining equipment needs to cool down before slag discharge, and the cooling time of a single furnace needs 2-3 hours, and the slag discharge time is slightly longer. In addition, the furnace door needs to be opened, and the environment for manual steel wire drawing is slightly worse, and the safety and environmental protection factor is not as high as that of continuous equipment.

The whole system of the continuous waste tire refining equipment is fully enclosed, the carbon black is packed in a centralized manner, there is no dust discharge, and the workshop environment is excellent.

The intermittent waste tire refining equipment needs to open the furnace door, the workshop has a slightly dusty smell, and the workshop environment is slightly poor.

Compared with intermittent equipment, the only disadvantage of continuous waste tire refining equipment is that the initial investment cost of equipment is higher, while the initial investment cost of intermittent equipment is lower, and the price is about 300,000 yuan. Therefore, bosses who are still struggling with how to choose waste tire refining equipment can choose according to the above differences between continuous tire refining equipment and batch tire refining equipment, as well as their own conditions and needs, or you can leave a message or call Henan Dongying Company for consultation. Our engineers and technical leaders will customize the product processing plan and supporting equipment for you to meet your diverse production needs.
