Abstract
The invention relates to an upper part inflation system of a flotation machine, which comprises: the air supply pipe is used for introducing air from the air blower into the main shaft of the flotation machine; the adjusting valve is arranged on the air supply pipe and used for adjusting the air volume; and the rotary joint is used for connecting the rotary flotation machine main shaft with the fixed air supply pipe of the air charging pipeline. According to the upper part inflation system of the flotation machine and the flotation machine thereof, during operation, air directly enters the hollow shaft through the inflation pipeline through the rotary joint without passing through the bearing body, and the sealing element in the bearing body is only used for oil sealing and dust prevention without preventing leakage of pressurized air, so that the sealing difficulty between the bearing body and the main shaft is greatly reduced, and the operation reliability of equipment is improved.
Description
Technical field
The present invention relates to ore dressing and metallurgical technology field, particularly relate to a kind of flotation device top gas charging system and possess the flotation device of this system.
Background technology
Flotation device is a kind of preparation equipment, and non-ferrous metal, ferrous metal and nonmetallic mineral sort the flotation device that industry adopts and be made up of electric machine, spindle unit and cell body parts usually.During flotation device work; Electric machine drives the rotation of main shaft impeller and stirs ore pulp in the cell body, and the air that will charge into simultaneously in the cell body cuts into minute bubbles, and the formation mineral laden bubble is adhered in the mineral grain collision in bubble and the ore pulp; Mineral laden bubble rises to mineral syrup liquid and forms froth bed, accomplishes floatation process.
As shown in Figure 1; The inflation mode of present domestic flotation device is the middle part air inlet through flotation device main shaft bearing body 5 '; To get into hollow shafts inner in several perforates through hollow shaft 6 ' top again, and be transported to the air distributor that is positioned at the spindle unit lower end by hollow shaft and distribute.Wherein 1 ' is the flotation device cell body, and 2 ' is the flotation device crossbeam, and 3 ' is butterfly valve, and 4 ' is air inlet pipe, and 5 ' is the main shaft bearing body, and 6 ' is hollow shaft.
Owing to charge into the flotation device gas inside and have certain pressure, this pressure is relevant with the impeller submergence, and generally speaking, flotation device is big more, and the impeller submergence is big more, and it is big more to charge into the required pressure of flotation device gas inside.In conjunction with Fig. 1; When adopting this inflation mode to inflate; There have the air of pressure must at first get into the main shaft bearing body to be inner, and this has proposed very high request to the bearing body of flotation device especially large flotation machines and the seal sealing effectiveness between the hollow shaft, the bearing body phenomenon of end cap gas leakage leakage of oil up and down in the production practices process, often occurs; Bring a lot of inconvenience to execute-in-place, caused the waste of operating cost.Simultaneously, adopt the flotation device main shaft of this inflation mode and bearing body difficulty of processing big, manufacturing cost is high.
Summary of the invention
The technical problem that (one) will solve
The objective of the invention is deficiency, a kind of gas charging system and the flotation device thereof that can effectively avoid because of the not good oil leakage phenomenon that leaks out that causes of bearing body inner seal sealing effectiveness is provided, guarantee carrying out smoothly of production to above-mentioned flotation device inflation technology.
(2) technical scheme
In order to solve the problems of the technologies described above, the present invention provides a kind of flotation device top gas charging system, comprising:
Give airduct, be used for the air from air blast is introduced the flotation device main shaft;
Control valve is located at saidly on the airduct, is used to regulate the air quantity size; With
Swivel joint is used to connect the flotation device main shaft of rotation and fixing gas ducting is given airduct.
Preferably, native system also comprises stationary pipes, is used to strengthen the stability of whole gas charging system.
Preferably, native system also comprises flexible coupling, is located at saidly on the airduct, is used to cushion that a variety of causes causes to the airduct vibrations, for the stable operation of swivel joint creates conditions.
Preferably, said flexible coupling is elastomer connector.
Preferably, said control valve is a butterfly valve.
The present invention also provides a kind of flotation device with above-mentioned flotation device top gas charging system, also comprises: electric machine, spindle unit and cell body.
(3) beneficial effect
Through flotation device of the present invention top gas charging system and flotation device thereof; During operation; Air directly gets into quill shaft through gas ducting via swivel joint, and needn't pass through bearing body, and the inner seal of bearing body is only made the dustproof usefulness of oil sealing and needn't have been prevented the pressure leakage of air; Greatly reduce the sealing difficulty between bearing body and the main shaft, improved the equipment operational reliability.
