Description
Technical field
A kind of large flotation machines relates to a kind of floatation equipment that is used to sort non-ferrous metal, ferrous metal and nonmetallic mineral.
Background technology
At present, be used for the flotation device of non-ferrous metal, ferrous metal and nonmetallic mineral flotation, form by transmission device, motor, bearing body, crossbeam, foam pushing device, hollow spindle, impeller, stator, stator support and cell body usually.Along with the development of flotation technology equipment, floatation equipment is gradually to large scale development.Large-scale floatation equipment has that the erecting bed number is few, floor space is few, is easy to automatic control, the capital expenditure expense is few, the unit groove holds little, the high outstanding advantage of overall economic efficiency of installation power.But, also can produce a series of problems that need solution because flotation device maximizes.Subject matter is: 1, fed distance and local foam are stagnated a key factor of the purpose mineral processes index that is the large-scale flotation of influence.When flotation device was big, the foam delivery distance was longer, caused sticking in the course of conveying coming off of particle on the foam; And easily stagnate near the foam in the middle of the flotation device, and be easy to flow, and the foam that overflow is gone out all is newborn white foam, do not pass through the secondary enrichment, therefore reduced the technic index of purpose mineral near the foam at foam tank edge.2, the service life of consumable accessory.When flotation device was big, weight of equipment was bigger, during consumable accessorys such as replacing impeller, stator, a shelf, and the whole main shaft of slinging, replacing is difficult for; Consider that from the angle of economy also be that the longer the better the service life of consumable accessory in addition.3, the stability of flotation device.4, simplify the manufacturing process of flotation device as far as possible.
Present traditional flotator structure, foam pushing device is for singly pushing away the single foam tank structure of bubble awl; The height of downflow weir is fixing non-adjustable; Stator is fixed on the stator support that is welded on bottom land, and stator support is made up of steel pipe, doughnut-shaped steel plate, is welded with the short steel pipes that external diameter equates with warp in the steel pipe under the doughnut-shaped steel plate, and stator is connected by bolt with stator support; The motor tensioning apparatus is made up of motor bearing, motor support plate and tensioning screw, and tensioning screw is positioned at the top of motor.
The defective of tradition large flotation machines is:
1. because the flotation device volume is bigger, foam delivery distance is longer, singly pushes away the single foam tank structure of bubble awl and makes froth pulp in time not reclaim, and causes sticking in the course of conveying coming off of particle on the foam; And easily stagnate near the foam in the middle of the flotation device, and be easy to flow, and the foam that overflow is gone out all is newborn white foam, do not pass through the secondary enrichment, therefore reduced the technic index of purpose mineral near the foam at foam tank edge.
2. because the traditional stator structure, complex structure, the requirement on machining accuracy height, surface area is big, and is easy to wear under the long term of ore pulp, and service life is shorter relatively, and traditional stator structural material consumption is more.
3. because flotation device is bigger, flotator structure is comparatively complicated, and is higher relatively to requirement on machining accuracy.The tradition downflow weir is unadjustable, processes the careless slightly phenomenon that not blebbing of part will occur, can only be by the method levelling of cutting downflow weir, and modification is difficult for, and influences normally carrying out of producing.
4. because flotation device when big, the power of used motor is higher, and the weight of motor is also heavier relatively.The vibrations when load strengthens of traditional vertical machine tensioning apparatus are bigger, poor stability, and tensioning screw is positioned at motor top, and required tensile force is bigger.
Summary of the invention
