Description
Technical field
The utility model relates to a kind of low speed coal mill, is specifically related to the online ball adding device of a kind of coal pulverizer, belongs to field of mechanical technique.
Background technology
Steel ball, as the grinding main body of coal pulverizer, all needs to carry out installing new steel ball additional at set intervals.At present, the loading of coal pulverizer steel ball adds from charging aperture after mainly stopping mill, is unfavorable for the continuous operation of producing; Though some automatic ball-adding device can carry out when grinding machine runs adding ball, when being malleation in coal pulverizer cylindrical shell, sealing when adding ball can not be ensured again.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of rational in infrastructure, simple and practical online ball adding device.
For solving this technical problem, the utility model provides the online ball adding device of a kind of coal pulverizer, comprise score bucket and falling sphere pipe, the upper end of described bucket of scoring is connected with two layers of basis by expansion bolt, described falling sphere pipe is connected with the lower end of struggling against of scoring by holding ball device, described hold ball device upper end and score struggle against between have upper sealing valve by Flange joint, hold ball device lower end and there is lower sealing valve falling sphere pipe upper end by Flange joint, falling sphere pipe lower end is connected with raw coal inlet after inclined-plane buffering, at falling sphere pipe and raw coal inlet is attached enters to install sealing air interface.
Described bucket inner side of scoring is provided with the buffer board for slowing down the speed that steel ball declines.
The described buffer board holding in ball device the decrease speed be provided with for slowing down steel ball.
Beneficial effect: falling sphere pipe of the present utility model is connected with raw coal inlet, can realize adding ball online, holds ball device upper and lower side and connects seal valve respectively, ensure that sealing when steel ball loads.The utility model has the advantage that structure is simple, be easy to adjustment and safeguard, economize on resources, and is conducive to enhancing productivity.
Accompanying drawing explanation
Fig. 1 is structural representation front view of the present utility model;
Fig. 2 is structural representation left view of the present utility model.
In figure: 1 goal bucket, 2 upper sealing valves, 3 lower sealing valves, 4 hold ball device, 5 falling sphere pipes, 6 sealing air interfaces.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is specifically described.
The utility model comprises goal bucket 1 and falling sphere pipe 5.
The upper end of described goal bucket 1 is connected with two layers of basis by expansion bolt.
Buffer board for slowing down the speed that steel ball declines is installed inside described goal bucket 1.
Described falling sphere pipe 5 is connected with the lower end of goal bucket 1 by holding ball device 4, holds ball device 4 and is mainly used to carry steel ball.
The described buffer board holding in ball device 4 decrease speed be provided with for slowing down steel ball.
Described holding between ball device 4 upper end and goal bucket 1 has upper sealing valve 2 by Flange joint, hold ball device 4 lower end and there is lower sealing valve 3 falling sphere pipe 5 upper end by Flange joint, falling sphere pipe 5 lower end is connected with raw coal inlet after inclined-plane buffering, enters to install sealing air interface 6 at falling sphere pipe 5 with raw coal inlet is attached.
The course of work of the present utility model is as follows:
1) connect sealing air interface 6, lead to sealing air to raw coal porch;
2) open upper sealing valve 2, entered by ready steel ball hold ball device 4 through goal bucket 1, goal bucket 1 and the buffer unit held in ball device 4 effectively slow down the impact of steel ball to seal valve, avoid the damage of seal valve;
3), after steel ball has loaded, close upper sealing valve 2, open lower sealing valve 3, steel ball enters raw coal inlet through falling sphere pipe 5, and the incline structure of falling sphere pipe 5 effectively slow down the falling speed of steel ball, avoids the impact to coal pulverizer import;
4) add after ball completes, close lower sealing valve 3, close sealing air interface 6 simultaneously.
Falling sphere pipe of the present utility model is connected with raw coal inlet, can realize adding ball online, holds ball device upper and lower side and connects seal valve respectively, ensure that sealing when steel ball loads.The utility model has the advantage that structure is simple, be easy to adjustment and safeguard, economize on resources, and is conducive to enhancing productivity.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned, the restriction not to the utility model protection domain.On the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
