Structure and principle of horizontal spiral centrifuge:
The horizontal spiral centrifuge is a spiral unloading agent. The horizontal spiral centrifuge is mainly composed of a spiral conveyor and differential component with the same rotation drums, the same drum turning to the drum to the rotation, and a slightly lower rotary rotation shaft. When the suspension of the horizontal spiral centrifuge is to be separated, the suspension liquid is sent to the tube by the hollow rotation shaft, and the suspension is immediately thrown into the turning drum cavity of the centrifugal machine under the centrifugal force of a centrifugal drum to rotate at a high -speed rotation. Inside. The high -speed rotation drum of a horizontal spiral centrifuge produced a strong centrifugal force to throw a solid -phase particles with a liquid phase density on the inner wall of the drum to form a solid layer (because the ring, called the solid ring layer) water due to density Small and small centrifugal force, so it can only form a liquid layer on the inside of the solid ring layer, called the liquid ring layer. Due to the different speed of the spiral and drums of the horizontal spiral centrifuge, there is a relative movement (that is, the speed difference), and the horizontal spiral centrifuge uses the relative motion of the spiral and the drum to slowly promote the sludge layer of the solid ring layer. By the end of the turning drum, and after passing through the dry area, the liquid of the liquid ring layer of the liquid ring layer distributed by the rotary circle is continuously discharged from the weir port continuous \ overflow to the drum to form a separation liquid.
The horizontal spiral centrifuge is composed of two rotors, one is called a drum, and the other is a spiral unloader (referred to as spiral). When the rotating high -speed rotation of the rotary high -speed rotation of the horizontal spiral centrifuge, the inner materials in the drum rotate with the drum and are affected by the centrifugal force. The drum shaft is settled to the inner wall of the drum, and the spiral in the drum is lower than (planetary differentials) or higher than (line differential) rotating drums. By the outlet, the differential rotation speed of the external drum and the spiral depends on the speed of the main and auxiliary motor and the transmission ratio of differentials.
The main features of the horizontal spiral centrifuge:
1. Standard design and manufacturing of centrifuge design and manufacturing conforms to the standard specifications such as JB/T502-2004 spiral unloading agent and JB8525-1997 centrifuge safety standards.
2. High speed, high separation factor, large diameter ratio of high -speed, high -separation factor, and large diameter ratio. This type of centrifugal machine with a drum diameter below 530mm is generally above 300R/min, the separation factor is more than 2500, and the length ratio can be up to 5. Among them, the maximum speed of LW250X1000-N centrifugal machine is 5400R/mIM, and the separation factor can reach 4000.
3. Hirocco -centrifugal single -machine processing capacity. The diameter of the horizontal spiral centrifuge is 250, 300, 355, 400, and 500mm. The series of centrifugal descending machines are based on the latest fluid theory, with reference to the latest foreign structural design, the processing capacity is great, and the separation effect is good.
4. The vibration of the horizontal spiral centrifuge is small, the noise is low, and the carrying capacity is strong. This series of centrifuge bearing uses imported bearing, with high accuracy, strong carrying capacity, and high accuracy of component manufacturing. The centrifuge of centrifuge, low noise, and various performances are better than national standards.
5. The horizontal spiral centrifuge has multiple protection devices and is reliable. This series of centrifugal machines are generally equipped with differential overload protection or restricted puppets protection devices. According to the needs, safety protection devices such as vibration protection, temperature monitoring and protection, and feeding adjustment can also be configured.
6. The poor system performance of the horizontal spiral centrifuge is reliable. This series of centrifugal differentials generally use the planetary gear differential, and according to the needs, the hydraulic variable speed speed system can also be selected. Mechanical differentials generally use well -known domestic brands. Differential manufacturing accuracy, good performance, reliable operation.
7. The sealing and explosion -proof performance of the horizontal spiral centrifuge. For special separation occasions such as flammable and explosive, there are special design and manufacture seals and explosion -proof models to choose from. The service life of mechanical sealing is 8,000 hours, and the gas sealing life ensures more than 15,000 hours.
