The first spiral centrifuge has the practical value of modern China was made in 1954. Due to the centrifuge unique series of operation, processing capacity, power consumption per unit of production quantity is less, strong adaptability, etc. characteristics and obtained the rapid development, in more than 40 years of development, structure, function, parameter changes, respectively, the quality, production can continue to progress, planning to use a wider range, in the field of centrifuges always occupies an important position. In various international exhibitions and numerous of spiral centrifuge, centrifuge exhibited in the most attractive models, with good prospects for development.
China from the late seventy's preliminary introduction of spiral centrifuge, and production of various specifications of the foreign famous companies decanters were copied. Decanter centrifuge is a former Ministry of chemical industry, "the Seventh Five Year Plan" key projects of science and technology, Nanjing Luzhou machine factory in 1989 copied the angle of alfanx42o shaped cone (20) centrifuge (ie, L201) for corn protein respectively, and in 1992 made prototype; since then, Chongqing Jiangbei Machinery Factory, Liberation Army No. 4819 factory and Jinhua railway machinery factory etc. research developed a series of spiral unloading settling centrifuge, and successfully used in production practice.
To optimize the spiral unloading settling centrifuge function, our frequently asked questions on the centrifuge research, establish the spiral transport device parametric 3D finite element model, structural static analysis, obtained spiral conveyor under various loading conditions should stress field and displacement field, and with reference to the pressure vessel analysis planning method of checking the spiral conveyor stress intensity, examining the radial displacement of the helical blade. Laid a solid foundation for structural optimization planning.
China's aviation industry the shell element and ring unit coupling method for elastoplastic analysis of centrifugal impeller with splitter blades and all the results show that this method with high precision, good time. Also in our country developed optimization solution of the C program and deduce the spiral push torque calculation formula, and to the policy function, technology requirements as the constraint conditions, the use of optimization planning theory in complex optimization method of WL 600 a decanter centrifuge parameters of the induction analysis and quantitative selection. Is also put forward analyze all centrifuge drum with the two dimensional solid element, and finite element calculation of a domestic horizontal scraper centrifuge large diameter drum. The results show that the stress in the bottom of a rotary drum and a liquid blocking plate force level is low; in the rotating cylinder body should be at higher force levels, in the opening around the stress converged on the scene, virtual maximum elastic stress value is far greater than the material yield limit.
Our country also use finite element software ANSYS to establish two-dimensional finite element model of the large horizontal decanter centrifuge drum with double cone angle, the drum of the radial, axial deformation and stress spread and maximum stress point. The results show that double cone angle drum strength and stiffness were satisfied with the requirements, verify the double tapered structure safety. And qualitative analysis of the decanter centrifuge of the sediment conditions and drum cone angle cutter, spiral delivery vane angle B, blade pitch and the radius of the liquid pool and poor contact between speed an, discusses the improvement of transport conditions of slag planning thinking of decanter centrifuge. Group of experts commented on the feed concentration, separation factor, the influence of overflow radius and other parameters of WL 400 type centrifuge kaolin classification function, discusses horizontal spiral unloading centrifuge in chemical fiber titanium oxide classification in use, mainly discuss the feed concentration, the effect of feeding speed, speed, baffle scale, poor speed and other parameters on the classification of and analysis of the factors of the influence of various parameters on classification. They study for centrifuge operation parameters and the use of the best offers see.
In our country and on Spiral Sedimentation Centrifuge of the oscillatory function tests the vibratory centrifuge acceleration RMS with the processing capacity of the centrifuge, rotating speed of the drum and the suspension viscosity and density between the links and experimental with the inherent frequency of the centrifuge; for the sludge removal technology using domestic LWD a 430 type horizontal Spiral Sedimentation centrifuge and supplemented by high efficient organic flocculant. The test run showed that, the dehydration technology significantly, the moisture content of 9.8% to 98.5% of the sludge dewatering to 75% a 78% and liquid separation of sewage processing equipment, no obvious impact, eliminating the need for sludge formation is a serious problem of secondary pollution.
