Introduction to semi-trailer for transporting powder and particle materials and semi-trailer for transporting chemical liquids

Semi trailer for powder material transportation

Powder material semi-trailer is a special vehicle for the transportation of large quantities of dust materials (bulk cement). It is generally applicable to areas where the weight charge is strictly implemented according to national regulations, and the volume is generally between 35-45 cubic meters. It is applicable to the transportation and pneumatic unloading of fly ash, cement, lime powder, ore powder and other dry materials with particle diameters not greater than 0.1mm. When the vertical height of unloading reaches 15m, the horizontal conveying distance can also reach 5m.

The semi trailer powder material transport vehicle uses its own engine power to drive the vehicle mounted air compressor through the power take-off, and sends the compressed air into the air chamber at the lower part of the sealed tank through the pipeline, so that the cement on the fluidized bed is suspended into a fluid state. When the pressure in the tank reaches the rated value, open the unloading butterfly valve, and the fluidized cement is transported through the pipeline. It is made by domestic advanced technology, with novel design and durability. Air bag type has large bearing capacity, fast unloading speed and small residue. The integrated tank body has the characteristics of high overall strength, good rigidity, good pressure bearing and good service performance.

The fluidized bed in the tank is designed scientifically and arranged reasonably, which can effectively shorten the unloading time to 1.4T/min, improve the volume utilization rate of the tank, and reduce the residual ash rate, which is 0.2%. The tank body of the powder material transport vehicle adopts a double cone inward inclined horizontal structure, with double pipes for air intake and double cylinders for feeding. Its unloading speed and residual rate meet the requirements of the industry standard.

Semi trailer for chemical liquid transportation

The requirements for tank materials of chemical liquid semi-trailer are different according to the characteristics of the transported medium.

Commonly used chemical liquid tank body materials include stainless steel (202, 304, 316L), carbon steel, plastic steel (plastic lined tank), glass fiber reinforced plastic, aluminum tank, full plastic tank (polyethylene, polypropylene), etc. The full plastic tank series uses polyethylene as the main raw material formulation process, forming full plastic and plastic steel products in a single step, with seamless, impermeable, corrosion resistant, anti-aging, impact resistant, non-toxic, long life, low price and other characteristics, suitable for most acids Alkali, salt, alcohol, aldehyde storage, transportation, reaction, stirring, wastewater and gas treatment.

The steel belt is usually used to bind and fix the vehicle chassis as a transport tank. It is widely used in chemical, metallurgical, environmental protection, brewing, food, pharmaceutical, storage and transportation enterprises. The full plastic tank series uses polypropylene as the main raw material process. The 20MM thick polypropylene plate is welded with a special double-sided process. The tank body is reinforced with multiple wave boards in the middle, which is better than the polyethylene tank (<60 ℃) in high temperature resistance (polypropylene<85 ℃).

Plastic steel composite tank series (plastic lined tank): steel plastic composite anti-corrosion series products, which are integrally molded on the inner wall of the steel tank through the steel mesh transition structure, have the dual characteristics of PE anti-corrosion performance and metal strength. The use temperature is - 20 ℃~70 ℃. The products include pressure tank, large storage and transportation tank, reactor, ion exchange column, chemical tower, pipeline valves, etc., which are widely used in the storage, reaction and transportation tanks in the chemical industry. carbon

Steel tank series: the inside and outside are treated with meticulous anti-corrosion paint, which is suitable for the transportation of various non corrosive chemical liquids.

Use temperature: - 20 ℃~60 ℃, small scope of application (6-8 ㎜ thick carbon steel plate can be used to make tank body for concentrated sulfuric acid with concentration>97%). FRP tank has a wide scope of application. Due to its high brittleness and low toughness, when used as a transport tank, the tank body should not be larger. Aluminum tank is the best choice for transportation of liquid nitric acid. Stainless steel tanks are widely used, but the cost is high. The company has strong technical force, and can design and manufacture products satisfying users according to their requirements.

Shengrun's leading products include: LNG cryogenic liquid semi-trailer, aluminum alloy flammable liquid tank semi-trailer, ordinary semi-trailer, etc. Shengrun has an annual production capacity of more than 20000 vehicles. At present, more than 100 product models have been announced by the Ministry of Industry and Information Technology of the People's Republic of China, meeting national standards and reaching the international leading level.
