Description
Technical Field
The utility model relates to an unloading equipment, especially a can improve star type tripper of batching precision.
Background
The star-shaped discharger discharges the materials by the gravity of the materials and feeds the materials to the next material conveying device. Star type tripper upper end is equipped with the pan feeding mouth, and the lower extreme is equipped with the bin outlet, relies on rotatory blade to play the effect of carrying the material, and the rotatory process of blade is sealed with the shell of tripper, prevents that material transportation process from taking place the large tracts of land and spouting the material to material in the feed bin of higher level is sealed, prevents that gas from inhaleing humid air by the bin outlet and causes the material caking. The star-shaped discharger is suitable for drying powdery and small granular materials and is widely used in the industries of metallurgy, chemical engineering and the like. The current star type tripper has following problem at the process of unloading: when the blades rotate to the end part of the discharge port in the rotating discharging process, the blades and the shell are closed, and the discharging is not instantaneously carried out, so that the continuous and uniform discharging cannot be ensured. The precision requirement cannot be met for the occasions with high precision required by blanking. For example, in the sintering process of a metallurgical enterprise, strict requirements are imposed on the blanking amount of materials such as lime and the like in the batching process of sintered ores, and the material surface from a common star-shaped discharger to a conveying belt is in a non-planar wavy shape, so that the accurate proportioning of the sintered ores can be directly influenced, and the smelting requirements of a blast furnace are influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's drawback, provide a star type tripper that can improve the batching precision that keeps even unloading in succession.
The purpose of the utility model is realized by the following technical scheme:
the utility model provides a can improve star type tripper of batching precision, includes motor, shell, rotation axis and the blade of unloading, motor drive connects rotation axis one end, and the blade equipartition of unloading is on the rotation axis, and the blade assembly of unloading is in the shell, the last breach of unloading that is equipped with of the blade of unloading, the breach of unloading lie in the blade central line of unloading and unload between the blade tip, the breach position staggered arrangement of unloading of adjacent blade.
Above-mentioned can improve star type tripper of batching precision, the notch inboard distance of unloading is no less than 10 millimeters apart from the blade centerline distance of unloading, and the distance of the notch outside distance of unloading blade tip is not less than 20 millimeters.
According to the star-shaped discharger capable of improving the batching precision, the geometric shape of the discharging notch is rectangular or arc-shaped, and the depth of the discharging notch is 20-30 mm.
The star-shaped discharger capable of improving the batching precision has the same geometric shape and size of all the discharging gaps.
The utility model discloses to solving the discontinuity problem of unloading of star type tripper and designing, to the improvement that the blade of unloading of star type tripper goes on, set up the breach of unloading on every blade of unloading, the breach position of unloading of adjacent blade of unloading is crisscross. The improvement not only ensures the sealing performance of the end part of the blade, but also solves the problem that the blade is instantaneously closed and does not discharge. Adopt the utility model discloses, personally submit the plane state by the material of star type tripper unloading on the transportation belt, guaranteed the unloading continuity to improve the batching precision of sintering material, satisfied the requirement of accurate unloading.

FIG. 2 is a right side view of FIG. 1;
figure 3 is a schematic view of the discharge gap distribution on the discharge blade.
The reference numbers in the figures are: 1. motor, 2, rotation axis, 3, the blade of unloading, 4, the breach of unloading, 5, shell, 6, the blade central line of unloading, 7, bin outlet, 8, feed inlet.
Detailed Description
Referring to fig. 1-3, the star-type discharger of the present invention includes a motor 1, a housing 5, a rotating shaft 2, and a discharging blade 3. The motor transmission is connected with one end of the rotating shaft, the discharging blades are arranged on the rotating shaft and are uniformly distributed relative to the rotating shaft, the discharging blades are assembled in the shell, the upper part of the shell is provided with a feeding hole 8, and the lower part of the shell is provided with a discharging hole 7. Because each discharging blade intermittently passes through the discharging opening and each discharging blade is sealed with the inner wall of the shell, the materials are discharged from the discharging opening in a discontinuous state. To this problem the utility model discloses the structure to the blade of unloading improves, all sets up the breach 4 of unloading on each blade of unloading, and the breach of unloading is located the blade central line of unloading 6 and between the blade tip of unloading, and the breach position of unloading of adjacent blade adopts non-corresponding staggered arrangement mode. In order to ensure the sealing of the discharging blade and the inner wall of the shell, the distance from the inner side edge of the discharging gap to the centerline of the discharging blade is not less than 10 mm, and the distance from the outer side edge of the discharging gap to the end part of the discharging blade is not less than 20 mm. The geometry of the discharge gap can be rectangular as in the illustrated embodiment, or can be curved, with a depth of 20-30 mm. In order to ensure the dynamic balance of the moving process of the discharger, the discharging gaps on all the discharging blades have the same geometric shape and size and the distance from the discharging gap to the center line of the discharging blade is the same.
Adopt the utility model discloses a design, the blade of unloading always can be continuous discharge from the breach of unloading at rotatory in-process material, has consequently guaranteed the continuity of material unloading, improves unloading volume precision, satisfies the unloading volume requirement. The on-site use proves, the utility model discloses the unloading is the plane state to the charge level on the transportation belt, and the unloading is even in succession, and then has improved the batching precision of sintering material.
