　　Ruichen manufacturer wholesales WL350 horizontal screw centrifuge

　　Basic Overview of WL350 Horizontal Spiral Centrifuge:

　　Full name: Horizontal spiral settling centrifuge

　　Abbreviation: Horizontal screw centrifuge

　　It is a highly efficient centrifugal separation and settling equipment with horizontal spiral discharge and continuous operation. Horizontal spiral centrifuge can generally be divided into horizontal spiral filtration centrifuge and horizontal spiral settling centrifuge. The decanter centrifuge is suitable for dewatering sludge generated in industrial and civilian wastewater treatment processes, and is also widely used in industries such as chemical, light industry, pharmaceutical, food, and environmental protection.

　　Description of Main Components and Material Composition of WL350 Horizontal Spiral Centrifuge Equipment

　　The main components are: ⑴ Drum ⑵ Spiral Conveyor ⑶ Differential ⑶ Main Motor ⑶ Auxiliary Motor ⑶ Base

　　[1] Advanced planetary gear differential is selected, with a differential speed of 2-30r/min between the screw and the drum, a differential adjustment accuracy value of ≤ 1rpm, and a screw torque of ≥ 5000Nm. The differential speed is automatically feedback adjusted according to the changes in the load material and concentration, and the pushing power is automatically compensated to ensure the constant dryness of the material and obtain a good solid phase.

　　[2] The rotary drum is made of 304 stainless steel centrifugal casting, which enhances its corrosion resistance. The slag outlet of the conical cylinder is embedded with replaceable wear-resistant and corrosion-resistant nano diamond jade (ceramic) inserts. The inner wall surface of the drum is equipped with longitudinal wear reducing strips in the direction of logistics to protect the inner surface from wear.

　　The parts of the unit that come into contact with materials and liquids are made of 304 stainless steel material; During operation, the noise level of the unit is ≤ 85dB (A), and the vibration intensity is ≤ 5mm/s.

　　[4] The casing and hood are both made of 304 stainless steel, and the machine base is made of carbon structural steel. The bottom layer is sprayed with 80 μ m DFT of mica and iron oxide primer, and the surface layer is sprayed with 100 μ m of high-grade chloroprene rubber paint. All sealing gaskets in contact with the material are made of polytetrafluoroethylene material.

　　The main and auxiliary motors of the horizontal screw machine adopt well-known domestic brand motors that comply with the IEC43-1 standard, 380V, three-phase, 50Hz. The motor is a horizontal AC squirrel cage induction motor with a protection level in accordance with the IP55 standard and an insulation level of F. The rotary drum of the horizontal screw machine is driven by an electric motor and a frequency converter, with a smooth start and stepless adjustment during operation.

　　[6] The whole machine assembly is completed, and during the empty vehicle debugging stage, a computerized dynamic balancing instrument is used for full process testing, and a simulated load dynamic balancing experiment with water is conducted to ensure the stability and reliability of the machine operation.

　　Technical Performance and Advantages of WL350 Horizontal Spiral Centrifuge

　　[1] Composed of a cylindrical conical drum, an internal screw conveyor, and a differential, it can continuously dehydrate materials for 24 hours under the action of centrifugal force.

　　[2] The spiral adopts a patented structural design, which increases the squeezing force inside the spiral, greatly reduces the moisture content of the sludge, and ensures the constant dryness of the sludge. The spiral structure of the patent improves the slag discharge conditions, ensuring smooth slag discharge without material blockage during operation, and can adapt to dehydration of materials of various compositions.

　　[3] It does not require watering when starting up, making installation and use extremely convenient and saving industrial water.

　　[4] AdoptingDual frequency conversion drive system,This drive system is widely used internationally (such as Sweden's a-Laval, Germany's Flottwege, Westfalia (GEA), Italy's PIERALISI, Austria's ANDRITZ, etc.). The main motor of the system is controlled by a frequency converter and directly drives the centrifuge drum through a V-shaped tape. The auxiliary motor of the differential system is controlled by a frequency converter to control the input shaft speed of the planetary gear differential through V-shaped tape, in order to achieve the purpose of controlling the screw differential speed.
