Description
Technical field
The utility model relates to water injector in a kind of vertical mill, refers to a kind of water injector that is applicable to that the high density dust atmosphere is worked down in the Vertical Mill especially, belongs to the milling equipment field.
Background technology
Known, the bed of material on the Vertical Mill mill must keep certain water content, stablizes the material bed with the frictional force of keeping certain limit between the slag material particles.Moisture is crossed and is exceeded low mill output decline, the bed of material instability of all making.
At present, common Vertical Mill water injector is vertical single-point water spray, Chinese patent (CN200620043160.5) name that the applicant applied on June 26th, 2006 is called the utility model patent of " water injector in a kind of vertical mill ", change the bilateral water injector into by original one-sided water spray, reached the purpose that prevents the grinding machine vibrations.But in process of production, pipeline have under the high density dust atmosphere of certain flow rate easy to wear, if untimely replacing will influence the operate as normal of water injector; Be intermittent water spray as crossing water injector in addition, after cutting off the water, water spray pore (groove) is piled up easily under the high density dust atmosphere and is stopped up, and causes and can not spray water, and production technology is caused have a strong impact on.Therefore, Vertical Mill water injector replacing, water jet after the water pipeline wearing and tearing in working environment easily piled up the technical problem that obstruction is this area urgent need solution.
Summary of the invention:
Technical problem to be solved in the utility model is to provide water injector in a kind of vertical mill, this device can be under the high density dust atmosphere operate as normal, can not produce obstruction; Be convenient to the replacing behind pipe wear in addition, to overcome the deficiency that prior art exists.
The technical scheme in the invention for solving the above technical problem provides water injector in a kind of vertical mill, comprise horizontally disposed outer compressed air piping, be set in the internal layer waterpipe in this skin compressed air piping, the top of described outer compressed air piping is provided with the top end cover that is used for sealing described internal layer waterpipe, tail end is provided with the afterbody end cap with the inner layer pipe bolt, described outer compressed air piping is connected with compressed air inlet pipe near the top position of afterbody, and described outer compressed air piping is axially arranged with plurality of tube holes, is bolted with the hole for water spraying pipe that passes described pore on the described internal layer waterpipe;
Leave the gap between described hole for water spraying pipe and the described pore wall.
Further improvement is that the gap of described hole for water spraying pipe and described pore is 0.5mm～1mm.
As further improvement, described outer compressed air piping is provided with flange connecting apparatus near compressed air inlet pipe.
The beneficial effects of the utility model are: use above-mentioned water injector, the internal layer waterpipe is a water pipe, the logical compressed air of outer compressed air piping, after internal layer waterpipe water spray stops, outer compressed air piping compressed air still circulates, make the peripheral air curtain that forms of hole for water spraying pipe, avoid dust to be attached on the pore and to result in blockage.Outer compressed air piping is provided with flange connecting apparatus near compressed air inlet pipe, is convenient to change after certain wear extent is arranged, and has guaranteed the operate as normal of this water injector, guarantees that production technology normally uses.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the sectional structure chart of water injector in the utility model vertical mill
Fig. 2 is the enlarged drawing of A part among Fig. 1, can find out that the hole for water spraying pipe 7 and the position of compressed air piping 1, internal layer waterpipe 2 concern
Among the figure: 1, outer compressed air piping 2, internal layer waterpipe 3, top end cover 4, afterbody end cap 5, compressed air inlet pipe 6, flange connecting apparatus 7, hole for water spraying pipe 10, pore 101, pore wall D1, hole for water spraying bore D2, hole for water spraying external diameter of pipe
The specific embodiment:
As shown in Figure 1, described internal layer waterpipe 2 horizontal positioned of water injector in the vertical mill described in the utility model, the tube wall of its below axially is bolted with some hole for water spraying pipes 7, described internal layer waterpipe 2 outer also sheathed one outer compressed air pipings 1, described outer compressed air piping 1 below is provided with the pore 10 that hole for water spraying pipe 7 is passed, the general outer tube wall that exposes outer compressed air piping 1 slightly of hole for water spraying pipe 7, also can be in concordant outer compressed air piping 1 of outward appearance wall and internal layer waterpipe 2 be provided with top end cover 3, the bracing frame of top end cover 3 and Vertical Mill this top end cover 3 of (not shown) that is connected is used for supporting the support of internal layer waterpipe 2 and the sealing of outer compressed air piping 1, outer compressed air piping 1 tail end is provided with the afterbody end cap 4 with internal layer waterpipe 2 bolts, it and outer compressed air piping 1, internal layer waterpipe 2 is and is threaded, described outer compressed air piping 1 is connected with compressed air inlet pipe 5 near the top position of its afterbody.
As can be seen from Figure 2, leave the gap between described hole for water spraying pipe 7 and the described pore wall 101, described hole for water spraying pipe 7 is preferably 0.5mm～1mm with the gap length of described pore.Described outer compressed air piping 1 is provided with flange connecting apparatus 6 near compressed air inlet pipe 5 parts, and this flange connecting apparatus 6 is connected water injector in top end cover 3 is fixed this vertical mill with the outside (not shown) of Vertical Mill.
The water injector operation principle is in the vertical mill of the present utility model:
