Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, the utility model wet ball mill feed pipe leak-proof device, it is characterized in that by the half-cone that two taperings are respectively equipped with engaging lug 6 gather materials the cover 9, the securing member 8 that is connected of engaging lug 6 therewith, along the circumferential direction evenly be located at two described half-cone, one group the gather materials cover striker plates 4 of cover in 9 that gather materials, along the circumferential direction evenly be located at one group of feed pipe striker plate 5 of ball mill feed pipe 7 outer surfaces, evenly be located at gather materials one group of end face striker plate 3 on the ball mill end face of cover in 9 of two described half-cone, connecting two half-cone cover 9 that gathers materials forms with one group of set bolt 2 of end cover of ball mill 1, the quantity that striker plate needs is determined according to the diameter of feed pipe, feed pipe 7 diameters are big more, the quantity of cover striker plate 4 and feed pipe striker plate 5 of gathering materials is many more, its effect is that formation one deck is material bed on cover inboard and this end cover of ball mill surface, place and feed pipe outer wall are gathered materials in taper, so that the minimizing material is to the taper cover that gathers materials, the wearing and tearing of end cover of ball mill and feed pipe 7.Two described half-cone cover 9 that gathers materials connects into gather materials cover and being socketed on the ball mill feed pipe 7 of a taper by described securing member 8, and is connected with end cover of ball mill 1 by described one group of set bolt 2.
