Abstract
The utility model relates to the field of cement production equipment, particularly relates to a water jet device for a raw material vertical mill and aims to provide the water jet device for the raw material vertical mill, which has more excellent water jet performance. The utility model adopts the technical scheme as follows: the water jet device for the raw material vertical mill comprises a grinding cavity, grinding rollers uniformly arranged in the grinding cavity, and grinding discs which are in friction coordination with grinding rollers and capable of achieving the function of material grinding, and further comprises shower pipes, wherein the shower pipes extend in to the grinding cavity through grinding cavity walls; shower nozzles of the shower pipes are arranged on the friction surfaces between the grinding rollers and the grinding discs. According to the water jet device for the raw material vertical mill, the shower pipes are arranged above the friction surfaces between the grinding rollers and the grinding discs, so that the shower nozzles of the shower pipes can directly spray water on friction surfaces between grinding rollers and the grinding discs and enable water to be dispersed on the grinding discs under the rotating centrifugal force of the grinding rollers and the grinding discs. Therefore, that ground particles are uniformly mixed is finally achieved. The water jet device for the raw material vertical mill, provided by the utility model, and can be applied to raw material vertical mills, particularly raw material vertical mills for producing cement.
Description
Technical field
The utility model relates to cement manufacture plant field, especially a kind of raw material vertical-grinding water injector.
Background technology
In the time using raw material vertical-grinding water injector to carry out manufacture of cement, need to rotate levigate abrasive particle to grinding roller and mill and apply suitable water.The water applying due to traditional raw material vertical-grinding water injector can only be positioned at bottom mill central authorities, even if so grinding roller and mill also can be because the centrifugal force of mill central authorities is little in rotation, and the water that causes applying cannot be centrifuged power and is distributed to uniformly on the rubbing surface between grinding roller and mill.So far, can cause product owing to producing levigate middle shortage water to off quality.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of raw material vertical-grinding water injector with more excellent water spray performance.
The utility model solves the technical scheme that its technical problem adopts: raw material vertical-grinding water injector, comprise mill chamber, be evenly arranged at grinding roller in mill chamber, with grinding roller frictional fit and realize the mill of abrasive material function, also comprise sparge pipe, described sparge pipe enters in mill chamber by mill chamber wall, and the shower nozzle of sparge pipe is arranged at the top of rubbing surface between grinding roller and mill.
Further, on the shower nozzle of described sparge pipe, be provided with atomizing spray hole.
Further, on sparge pipe outer wall, be provided with wear-resistant protection cover.
Further, described grinding roller is four, and grinding roller is uniformly distributed around mill chamber central axis, and the equal correspondence of each grinding roller is provided with mill and sparge pipe.
The beneficial effects of the utility model: by sparge pipe being set above rubbing surface between grinding roller and mill, the shower nozzle of described sparge pipe can directly be sprayed onto water on the rubbing surface between mill and mill, can allow water diffuse on mill under the rotary centrifugal force of grinding roller and mill, and final realization mixed with the even of abrasive particle, greatly improve the quality of products, also saved water and electricity consumption in producing.The utility model can be applied to be produced in the raw material vertical-grinding water injector that cement is representative.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure, be labeled as: mill 1, rubbing surface 11, mill chamber 2, tremie pipe 21, grinding roller 3, sparge pipe 4, shower nozzle 41.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Raw material vertical-grinding water injector as shown in Figure 1, comprise mill chamber 2, be evenly arranged at grinding roller 3 in mill chamber 2, with grinding roller 3 frictional fit and realize the mill 1 of abrasive material function, also comprise sparge pipe 4, described sparge pipe 4 enters in mill chamber 2 by mill chamber 2 walls, and the shower nozzle 41 of sparge pipe 4 is arranged at the top of the rubbing surface 11 between grinding roller 3 and mill 1.
In order to realize the water being sprayed onto on rubbing surface 11, can along with the rotation of grinding roller 3 and mill 1, the power that is centrifuged scatter uniformly, and allow water fully mix with abrasive particle, the utility model is arranged at sparge pipe 4 top of the rubbing surface 11 between grinding roller 3 and mill 1, guarantees that the water applying is being not to apply from bottom mill central authorities.Like this, because grinding roller 3 and mill 1 can rotate, water naturally can be centrifuged power and disperses and hold uniformly, and finally fully mixes with abrasive particle.
In order to make the atomizing effect of the water that shower nozzle 41 sprays better, obtain more excellent mixed effect, can rotate such scheme: on the shower nozzle 41 of described sparge pipe 4, be provided with atomizing spray hole.Water by the ejection of described atomizing spray hole be made up of very little particle, then under grinding roller 3 and mill 1 rotary centrifugal force effect, can be more abundant with mixing of abrasive particle.
In order to allow the sparge pipe 4 extending in mill chamber 2 there is longer service life, can be chosen on sparge pipe 4 outer walls wear-resistant protection cover is set.Described wear-resistant protection cover is set and can greatly reduces the destruction of abrasive grain to sparge pipe 4 tube walls, reduce user because of the destroyed maintenance cost of additionally paying of sparge pipe 4.
In conjunction with concrete practical experience, can select described grinding roller 3 quantity is four, and grinding roller 3 is uniformly distributed around mill chamber 2 central axis, and the equal correspondence of each grinding roller 3 is provided with mill 1 and sparge pipe 4.Due in a mill chamber 2, tremie pipe 21 is positioned at mill chamber 2 centers, can rationally utilize the space between tremie pipe 21 and mill chamber 2 walls, and the quantity of uniform four grinding rollers 3 is comparatively suitable, guaranteed that grinding roller 3 does not interfere with each other each other in the time producing, and has rationally utilized again the space in mill chamber 2.
