Abstract
The utility model provides a high-efficiency dynamic separator which comprises a top cover device, a transmission device, a coal-falling pipe, a coal powder outlet pipe, and a C-shaped rotating cage, wherein the C-shaped rotating cage consists of an external cone, an internal cone, vertical vanes, and a bottom ring. The internal cone is fixed at the inner side of the internal cone, and the bottom ring is disposed under the external cone. A certain number of vertical vanes are uniformly distributed and fixed on the bottom ring, and are connected with the outer wall of the external cone. Moreover, the bottom of the C-shaped rotating cage is opening. The separator is characterized in that when the C-shaped rotating cage rotates, the separator can achieve the air suction from the bottom of the C-shaped rotating cage. The C-shaped rotating cage of the separator can achieve the air suction from the bottom, thereby changing the track of air in the separator, enabling the coal powder on a grinding disc to be effectively taken away, greatly reducing the phenomena of repeated grinding of the coal powder, greatly improving the grinding efficiency, and remarkably improving the force of a coal grinding machine.
Description
Technical field
The utility model relates to a kind of high-efficiency dynamic separator, belongs to coal dust classifier technical field.
Background technology
Medium-speed pulverizer (HP formula, ZGM formula, MPS formula) is widely used in thermal power plant, raw coal is broken and is milled into coal dust between the grinding roller of medium-speed pulverizer and mill, one time hot blast is blown into coal pulverizer inside from the lower edge of mill, coal dust is transported to the coal dust classifier on coal pulverizer top, separator separates thickness coal dust and the coal dust of qualified fineness is transported to boiler combustion, and underproof coal dust is turned back in grinding machine and continues to grind.
Fig. 1 uses the medium-speed pulverizer coal dust of static separation device to separate schematic diagram, Fig. 2 uses the medium-speed pulverizer coal dust of conventional dynamic separator to separate schematic diagram, one time hot blast rises by the edge of mill 1, peripheral coal dust can only be carried to separator separates, and the coal dust at middle part can not be taken away effectively by hot blast, this part coal dust prolonged stay, in coal pulverizer, has greatly reduced the grinding efficiency of coal pulverizer.
Summary of the invention
The purpose of this utility model is to provide a kind of grinding efficiency that can effectively improve medium-speed pulverizer, and then improves the dynamic separator of pulverizer capacity.
For achieving the above object, the technical solution of the utility model is to provide a kind of high-efficiency dynamic separator, comprise cover device, transmission device, coal spout, discharge pipe and C type pivoting leaf cage, C type pivoting leaf cage is by outer cone, inner cone, vertically blade and base ring composition, inner cone is fixed on outer cone inner side, base ring is placed in outer cone below, the vertical blade of some is uniformly distributed to be fixed on base ring and with outer cone outer wall and is connected, and C type pivoting leaf cage bottom-open, it is characterized in that: in the time that C type pivoting leaf cage rotates, high-efficiency dynamic separator can be realized from the bottom air draught of leaf cage.
A kind of high-efficiency dynamic separator that the utility model provides is by using the C type pivoting leaf cage of bottom-open, in the time that rotating, can realize by C type pivoting leaf cage from the bottom air draught of leaf cage, hot blast is carrying coal dust and is entering in pivoting leaf cage from the bottom of C type pivoting leaf cage, after accelerated rotation, discharge the separation that realizes thickness coal dust from vertical impeller clearance.Fig. 3 uses a kind of medium-speed pulverizer coal dust of high-efficiency dynamic separator to separate schematic diagram, compare with Fig. 2 with Fig. 1, because hot blast can enter from C type pivoting leaf cage bottom, make whole coal dust region have hot blast to pass through, coal dust can more effectively be pulled away and can not be trapped in grinding machine, thereby greatly improve grinding efficiency, exerting oneself of coal pulverizer promoted significantly.
The utility model has overcome medium-speed pulverizer separator the deficiencies in the prior art, can effectively improve the coal dust of coal pulverizer and exert oneself, thereby reduce cost of electricity-generating, reaches energy-saving and cost-reducing object.

Detailed description of the invention
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
A kind of high-efficiency dynamic cyclone separator arrangement schematic diagram that Fig. 4 provides for the utility model, in conjunction with Fig. 3, Fig. 5 and Fig. 6, taking HP medium-speed pulverizer as example, one time hot blast rises and enters coal pulverizer along the outer rim of mill 1, mill 1 top has been full of the coal dust suspending, and hot blast carries coal dust to be continued to rise.A kind of C type pivoting leaf cage 13 of high-efficiency dynamic separator 10 is made up of outer cone 14, inner cone 15, vertical blade 16 and base ring 17, inner cone 15 is fixed on outer cone 14 inner sides, base ring 17 is placed in outer cone 15 belows, the vertical blade 16 of some is uniformly distributed to be fixed on base ring 17 and with outer cone 14 outer walls and is connected, because C type pivoting leaf cage 13 bottoms are opened wide, when rotation, will produce air draught effect, the hot blast of rising is directed into the bottom of C type pivoting leaf cage 13, is drawn in C type pivoting leaf cage 13 from bottom.After hot blast is carrying coal dust and together rotates with vertical blade 16 in C type pivoting leaf cage 13, discharge from the gap between vertical blade 16.Hot blast and the coal dust of discharging from C type pivoting leaf cage 13 are rotating the top that rises to separator, enter discharge pipe 4 after bending.The mixture of hot blast and coal dust is in rotation and bending process, and the thickness that has fully realized coal dust separates.A kind of high-efficiency dynamic separator 10 has a very large change wind powder trajectory mark 8, nearly cover the top of whole mill, in in coal pulverizer, ground coal dust can be taken away timely and can be trapped in for a long time, greatly reduce coal dust and repeated the generation of grinding, thereby greatly improve grinding efficiency, exerting oneself of coal pulverizer promoted significantly.
