Intelligent improvement of control system for tubular centrifuge

The intelligent control system of tubular centrifuges has been improved. More and more centrifuges have set up safety monitoring systems, including temperature control, rotary head overspeed identification and locking monitoring. Sensors and microcomputer control system all over the fuselage constitute a perfect monitoring system, which can feed back the status of itself in real time, and give timely protection instructions and fault information. This not only facilitates maintenance, but also prevents the expansion of machine damage. The bus chip system with high integration simplifies the wiring design and improves the integration. The circuit is very simple, simple but not simple; GQ clarifies type: used to separate various suspensions that are difficult to separate. It is especially suitable for solid-liquid separation with small concentration, high viscosity, fine solid particles and small solid-liquid gravity. For example, the development history of equation centrifuges was developed, such as various pharmaceutical solutions, glucose washing and tide, malic acid, various oral liquids, clarification of Menispermum, clarification of coal tar and graphite, extraction of various proteins, saponins and pectin, refining of molasses, blood separation, vaccine mycelium, sedimentation of various glucose, paint, resin, rubber solution purification, equation centrifuge development history. Inside the drum there is a set of disc-shaped parts which are overlapped with each other. There is a small gap between the discs. The suspension (or emulsion) is added to the drum by a feed tube located in the center of the drum. When the suspension (or emulsion) flows through the gap between the discs, the solid particles (or droplets) settle on the disc under the action of the centrifuge to form sediment (or liquid layer). The sediment slides along the disc surface and separates from the disc and accumulates in the large diameter part of the drum. The separated liquid is discharged from the drum through the liquid outlet. The role of the disc is to shorten the settling distance of solid particles (or droplets) and expand the settling area of the drum. The production capacity of the separator is greatly improved due to the installation of discs in the drum. The solid accumulated in the drum is removed manually after the separator is shut down, or discharged from the drum by slag discharging mechanism without stopping the machine.

The structure of the centrifuge drum has a decisive influence on the use, operation, production capacity and power of the centrifuge. On the other hand, due to the high-speed rotation of the drum itself (its working speed is usually between hundreds of revolutions per minute to tens of thousands of revolutions per minute), it is affected by centrifugal force. Under the action of centrifugal force, great working stress will be produced in the drum body. Once the strength is damaged, it will cause great harm, especially when the stress is too high, it will cause serious personal injury Injury accidents. At the same time, for the high-speed rotating drum, the stiffness of the drum is also very important. If the rigidity of the drum is not enough, the geometric shape of the drum will change obviously. If it is light, the drum will collide with the shell, and the parts will be damaged; if the drum is heavy, it will burst and even cause personal injury. Over the years, due to improper drum design, drum manufacturing quality is not high, leading to serious accidents. This has attracted the attention of designers, manufacturers and user departments. The diagnosis, analysis and Research on the causes of accidents of tripod centrifuge are often carried out. The material of the tubular separator enters the lower part of the high-speed rotating drum from the feeding pipe in the center of the top of the separator, and enters the thin-layer gap formed by adjacent discs from the outer edge of the disc group, and is rotated at high speed. Due to the different proportion of water, yeast cells and solid particles in yeast milk, it is divided into three parts by inertial centrifugal force The outer sleeve of the central feeding pipe flows out, and the yeast concentrate with a large proportion flows from the reverse side of the disc to the bottom of the drum, and continuously flows out through nine concentration tubes and nine nozzles which are not evenly distributed around the bottom. The residue and other substances are deposited on the drum wall and discharged when the residue is discharged after separation.
