The cement production line is a cement equipment production line consisting of a series of equipment for producing cement. The method mainly comprises the processes of crushing and pre-homogenizing, raw material preparation and homogenizing, preheating and decomposing, cement clinker sintering, cement grinding and packaging and the like. For a cement raw meal fine grinding production line, a raw meal vertical grinding mill is commonly used, crushed raw materials such as limestone, clay, iron ore, coal and the like are fed into the raw meal vertical grinding mill through a feed port of the raw meal vertical grinding mill, and the feed rate is controlled at the feed port of the raw meal vertical grinding mill through a feed valve; and because a plurality of blocky raw materials which are not completely damaged exist in the crushed raw materials, the raw materials have great impact on the feed valve, the air leakage is serious after the valve plate and the lining plate are abraded, the failure rate is high, and the influence on the long-term stable operation of the mill production process and equipment is great.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art's is not enough, provides a cement manufacture raw grinds feed arrangement immediately. The problem of impact on a feed valve when raw materials for cement production are fed through a vertical mill is solved.
In order to achieve the above purpose, the present invention is achieved by the following technical solutions.
The utility model provides a cement manufacture raw material grinds feed arrangement immediately, includes that rubbing crusher and raw material found the mill, the feed inlet that raw material found the mill is provided with the feed valve, still includes chute, lower chute, rotary vane feeder and shale shaker, the discharge gate of rubbing crusher is connected with rotary vane feeder's feed inlet through last chute, rotary vane feeder's discharge gate is connected with the feed inlet of shale shaker, the thin material export of shale shaker is connected with the feed inlet that raw material found the mill through lower chute, the coarse fodder exit linkage of shale shaker has the conveyer belt, the discharge gate of conveyer belt is connected with the collecting hopper.
Furthermore, the feeding valve is a dividing wheel feeding valve.
Further, the blades of the impeller feeder are provided with wear plates.
Furthermore, the center distance of the feeding hole of the impeller feeder and the center of the shell of the impeller feeder have an eccentric distance.
Further, the impeller feeder housing liner is provided with a wear resistant layer.
Utility model does for the produced beneficial effect of prior art.
The utility model discloses increased rotary vane feeder and shale shaker between the rubbing crusher of traditional raw meal fine grinding production line and the vertical mill, on the one hand rotary vane feeder can solve and go into the mill material and block dead problem because of having the granularity big, on the other hand increases the shale shaker at the entry of raw meal vertical mill, further screens out the bold material, has guaranteed the normal operation of raw meal vertical mill, can not cause great impact and wearing and tearing to the feed valve of raw meal vertical mill; furthermore, the wear-resistant plate is welded on the impeller blade of the impeller feeder, so that the service life of the impeller is prolonged; the eccentric distance exists between the center distance of the feed inlet of the impeller feeder and the center of the shell of the impeller feeder, and the impeller feeder is more suitable for the entrance of materials with larger particles. The device effectively reduces the material volume entering the raw material vertical mill, reduces the impact and abrasion of the material on the feeding valve, and improves the service life of the equipment and the production stability.
Drawings
FIG. 1 is a schematic structural diagram of a raw material vertical mill feeding device of the present invention;
in the figure, 1 is a pulverizer, 2 is a raw material vertical mill, 3 is an upper chute, 4 is a lower chute, 5 is a blade feeder, 6 is a vibrating screen, 7 is a conveyor belt, and 8 is a collecting hopper.
Detailed Description
In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
As shown in fig. 1, the raw material feeding device for cement production comprises a pulverizer 1 and a raw material vertical mill 2, wherein a feeding valve is arranged at a feeding port of the raw material vertical mill 2, and the feeding valve is a dividing wheel feeding valve. Raw material grinds feed arrangement immediately still includes chute 3, lower chute 4, rotary vane feeder 5 and shale shaker 6, and the discharge gate of rubbing crusher 1 is connected with rotary vane feeder 5's feed inlet through chute 3, and rotary vane feeder 5's discharge gate is connected with the feed inlet of shale shaker 6, and the fine material export of shale shaker 6 is connected with raw material vertical mill 2's feed inlet through chute 4 down, and the coarse fodder exit linkage of shale shaker 6 has conveyer belt 7, and the discharge gate of conveyer belt 7 is connected with collecting hopper 8. The blades of the impeller feeder 5 are provided with wear plates. The center distance of the feed inlet of the impeller feeder 5 and the center of the shell of the impeller feeder 5 have eccentricity. The shell liner of the impeller feeder 5 is provided with an anti-wear layer.
The specific working process of the device is as follows: the material after rubbing crusher 1 is smashed gets into rotary feeder 5 through last chute 3, later gets into shale shaker 6, and shale shaker 6 sends the undersize material that meets the requirements into raw material vertical grinding machine 2 through lower chute 4, sends great material that does not meet the pan feeding requirement the great piece to conveyer belt 7, is sent to collecting hopper 8, carries out subsequent repulverize again.
