Yangshan Rotomolding Yacht Company developed a new rotomolding yacht technology
Recently, Yangshan Rotomolding Yacht Co., Ltd. reported to the Provincial Science and Technology Department that the “New 8.3 Meter Rotational Yacht Technology Development and Industrialization†project has passed expert demonstration.
Huang Xiaofeng, head of the company's rotomolding yacht project, said, "Rolling plastic yacht technology is an innovation of boat materials. It is inevitable for plastics to replace wood and plastic to replace steel. It also meets the requirements of environmental protection." Compared with the rotomolding yacht, it has good strength and seawater corrosion resistance. Its service life can reach more than 30 years. Its hull has large buoyancy and saves power resources. Because the proportion of manufactured materials is lighter than water, it will not be in case of sudden accidents. Sinking, safe and reliable.
Since the end of December last year, Yangshan Rotomolding Yacht Co., Ltd. has used domestic advanced rotomolding technology to cooperate with China Rotational Molding Association and Wuhan Rotomolding Enterprise to conduct industry-university-research cooperation, to develop rotomolding yacht and product materials and manufacturing process judgment, material raw material screening and Key technologies such as product manufacturing process research, mold design and manufacturing process research. "At present, the company has already possessed the hull structure design and mold manufacturing technology for the small plastic yacht with the captain under 15 meters. The processing temperature, time and technology for the rotomolding yacht molding have also matured." Huang Xiaofeng said.
Last year, Yangshan Rotomolding Yacht Co. produced two hulls of 4.6-meter and 6.7-meter rotomolding yachts, all of which were bought by foreign merchants. In order to increase the added value of the products, in February this year, the company implemented the “New 8.3-meter Rotomolding Yacht Technology Development and Industrialization†project, and carried out comprehensive series research and development of rotational molding products to form three series of rotational molding products. It is estimated that after the scale of the industry is formed, the annual production capacity of 2,000 rotomolding yachts of various specifications can be calculated, the output value can reach 400 million to 500 million yuan, and the profit can reach nearly 100 million yuan.
In addition to the use of rotomolding technology for yacht manufacturing, Yangshan Rotational Yachting Co., Ltd. has also turned its attention to the leisure fishing and aquaculture industry. In view of the current low safety factor and backward equipment of leisure fishing boats and aquaculture work vessels in the county, the company began to manufacture 8.3-meter-long leisure fishing boats and aquaculture work vessels at the request of customers. Huang Xiaofeng said that by manufacturing such ships, it will accumulate technical experience for the manufacture of rotomolding yachts.
DETAILED DESCRIPTION
Rotary Dryer, also known as rotary drum dryer,rotary drier.
According to different ways of heating raw material,the rotary dryer can be divided into direct heating-type rotary dryer and indirect heating-type rotary dryer. The rotary dryer can be classified into Coal Slime Rotary Dryer, Sawdust Dryer, Coconut shell dryer, slag rotary dryer and clay rotary dryer according to different raw materials.According to different structure, the rotary dryer can be divided into Three cylinder dryer, Double-drum Dryer.
Being widely used in building materials, metallurgy, chemicals, industrial drying slag cement limestone, coal, slag, clay and other materials.
The aircraft is mainly composed of the rotary, jan plate, transmission, seals, and other support equipment and components.
Being featured with a reasonable structure, well-produced, high yield, low consumption and operating convenience.
Offering products quality assurance, and highest free installation debugging agent can be checked with other plants than quality and prices.
How to improve rotary dryer`s efficiency
1. Improving temperature of drying medium of rotary dryer.
2. Improving flow rate of drying medium.
3. Improving internal structure of cylinder body of rotary dryer, adopting combined raise material.
4. Reducing material feeding granularity
5. Using concurrent processing set-up where possible
6. Adopting step-less speed regulator
Specifications of Rotary dryer
1. Standard testing
2. High process speed
3. Stable working conditions
4. ISO9000 and BV
Working principle of Rotary dryer
When rotary Dryer is operating, it shall be in direct contact with heated gas. The dryer consists of a large rotating cylindrical tube. In order to convey the material through the underside of dryer, the dryer should be slanted slightly to ensure that the discharge end is lower than the end of material feed .
Working Principle of Rotary Dryer: Material shall be dried to enter the dryer. When the dryer is rotating, a series of internal fins will lift the material by lining the inner wall of the dryer. When the material reaches certain height to roll the fins back, it will be fell back to the bottom of the dryer, then passing through the hot gas stream as it falls. This gas stream can either move toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be composed of a mixture of air and combustion gases from a burner, and in which case the dryer is known as a direct heated dryer. Alternatively, the gas stream may be made up of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases are not permitted to enter the dryer, the dryer shall be called an indirect-heated type. Indirect heated dryers are commonly used when product contamination becomes a concern. Read How Does HONGKE Rotary Dryer Work?
