In the process of injecting the material into the storage tank 100, the material enters the casing 120 with the smallest diameter first, and when the casing 120 with the largest diameter is filled with the material, the material overflows into the casing 120 with the relatively larger diameter of the outer ring of the casing, and so on, and when the casing 120 with the largest diameter is filled with the material, the material overflows between the tank body 110 and the casing 120 with the largest diameter, so that the whole tank body 110 is gradually filled with the material layer by layer, and thus the degree of rolling down of large particles in the material outwards can be reduced, and the uniformity of the material is increased. Set the distance between each sleeve pipe 120 top and jar body 110 top wall to equidistance d, the material is under sleeve pipe 120's restraint like this, only after sleeve pipe 120 that the diameter is minimum is annotated, just can form a less material heap in the height range of d, and along with the required sleeve pipe 120 increase of annotating in later stage, the material heap can become gentle gradually, thereby the phenomenon that the great part of granule rolls off from big material heap in the material has been reduced, thereby the segregation of powder has been alleviateed greatly, the material mixing of large granule and small granule is relatively even in making storage tank 100, thereby make the utility model discloses a material granule on powdery material loading attachment mixes is more even, especially be fit for the material loading of the powder of the uneven powder of granule size like the cake dry powder.

In order to ensure that the material has enough space to overflow to the outermost region, the distance d between the top of the sleeve 120 and the top wall of the can 110 is preferably set to be between 800mm and 1000 mm. Preferably, the distance a between the wall of the tank 110 and the wall of the adjacent casing 120 is equal to the distance b between the walls of the two adjacent casings 120 and equal to the inner diameter c of the casing 120 with the smallest diameter, and the widths of each layer in the tank 110 are the same, which is helpful for enabling the materials to enter the regions of each layer in a relatively close state, and the uniformity of the materials in the regions of each layer is similar, so that the uniformity of the material in the tank 110 is relatively good. The tank 110 may be any tank structure such as circular, rectangular, etc., but it is desirable that the cross-sectional shape of the sleeve 120 is the same as that of the tank 110, wherein circular is preferable, so that no sharp corner is formed on the wall of the sleeve 120 and the wall of the tank, which is convenient for the material to uniformly overflow outwards.

The casings 120 with the largest diameter are connected with the wall of the tank body 110 through the support rib plates 130, and the two adjacent casings 120 are also connected through the support rib plates 130, so that each casing 120 is suspended in the tank body 110. The plurality of support rib plates 130 are arranged along the radial direction of the tank 110, one or more layers of support rib plates 130 are arranged along the axial direction of the tank 110, and in this embodiment, an upper layer, a middle layer and a lower layer of support rib plates 130 are arranged to ensure the stability of each casing 120. The number of the supporting rib plates 130 in each layer is the same, and the projections of the supporting rib plates 130 in each layer in the axial direction of the tank body 110 are overlapped with each other, so that the blocking of the supporting rib plates 130 to blanking is reduced as much as possible. In order to stabilize the center of gravity of the storage tank 100 and to distribute the materials uniformly, the supporting rib plates 130 in the same layer are preferably distributed radially around the axis of the tank body 110, and in this embodiment, four supporting rib plates 130 are provided at each layer.

The diapire of jar body 110 sets up to the toper structure best, and the discharge gate of jar body 110 is located conical summit department, and the material of being convenient for like this is concentrated to its discharge gate. The bottom of each sleeve 120 is flush, so that the materials in each area in the tank body 110 can fall synchronously during discharging, and the materials in each area are mixed together to be discharged, thereby being beneficial to uniform discharging.

Preferably, the holding tank 100 further includes a discharger 140, as shown in FIG. 1, the discharger 140 being disposed below the tank 110. As shown in fig. 4 and 5, the discharger 140 includes a housing 141, a setting rotor 142 disposed in the housing 141, and a driver 143 that drives the setting rotor 142 to rotate. The top of the shell 141 is provided with a feed inlet 1412, and the bottom of the shell 141 is provided with a discharge outlet 1413. Two material stirring rotors 142 are arranged in the shell, the two material stirring rotors 142 are arranged side by side, each material stirring rotor 142 comprises a rotating shaft 1421 and material stirring blades 1422, the material stirring blades 1422 are fixedly arranged on the outer circumference of the rotating shaft 1421, and the rotating shaft 1421 is provided with a plurality of material stirring blades 1422 and is radially distributed by taking the rotating shaft 1421 as the center. As shown in fig. 5, two ends of the two rotating shafts 1421 are respectively connected to the front side wall and the rear side wall of the housing 141, the front side wall and the rear side wall of the housing 141 and the area between the two rotating shafts 1421 form a discharging channel 144, the feeding port of the housing 141 is located above, preferably directly above, the feeding port may be greater than or equal to the distance between the two rotating shafts. The specifications of the two material ejecting rotors 142 may be the same or different, the housing 141 may have any shape, and the material ejecting blades 1422 may have any shape such as a rectangle, a triangle, a trapezoid, or an irregular shape, as long as when the material ejecting blades 1422 of the two material ejecting rotors 142 located in the discharge channel 144 are located on the same plane, the combined shape of the two material ejecting blades 1422 is adapted to the shape of the discharge channel 144, so that the material ejecting blades 1422 can seal the discharge channel 144. For example, when the material shifting blades are rectangular, the shell is rectangular, the length of the material shifting blades is equal to the distance between the front side wall and the rear side wall of the inner side of the shell or slightly smaller than the distance between the front side wall and the rear side wall of the inner side of the shell, so that the plane formed by the axes of the rectangle and the two shafts formed by combining the two material shifting blades of the two material shifting rotors when the two material shifting blades are opposite is intersected with the shell to obtain a rectangular plane with the same size, and the material shifting rotors can move. For another example, as shown in fig. 6, the end surface of the free end of the material-shifting blade of one material-shifting rotor is a convex arc, the end surface of the free end of the material-shifting blade of the other material-shifting rotor is a concave arc, the lengths of the two are equal and the arcs are the same, when the two are opposite, that is, when the two are in the same plane, the two are combined into a rectangle which is matched with the front and rear side walls of the rectangular shell to close the discharging channel. The distance between the left and right side walls of the housing 141 and the adjacent kick-off rotors 142 is preferably made as small as possible to reduce the likelihood of material passing through areas other than the discharge chute 144, and to help prevent or reduce the flow of material out of the tripper 140 when the discharge chute 144 is closed.

When in use, the two material shifting rotors 142 rotate in opposite directions synchronously, and the material shifting blades 1422 between the two rotating shafts 1421 rotate from top to bottom, i.e. from the feeding hole to the discharging hole, thus, when the two material ejecting rotors 142 rotate, the two material ejecting blades 1422 in the discharging channel 144 are switched between two states of being in the same plane and not being in the same plane, when the two tripper blades 1422 in the discharge channel 144 are in the same plane, the discharge channel 144 is closed, when the two ejecting blades 1422 in the discharge channel 144 are not in the same plane, the ejecting blades 1422 will no longer close the discharge channel 144, allowing material to pass through the channel between the two ejecting blades 1422, thus, the continuous rotation of the material-ejecting rotor 142 can make the discharging channel 144 present the periodic changing states of door opening and door closing, when the door is opened, the material is discharged, and when the door is closed, the material is held by the material-pushing blade 1422 to close the discharger 140.

In addition, when the discharger 140 discharges materials, the two material stirring rotors 142 at the side of the feeding port of the casing rotate oppositely and concentrate the materials from two sides to the middle, when the materials shift along with the material stirring blades 1422, the materials can be upwards extruded to occupy the space on the upper part of the casing 141 or in the tank body 110 above the discharger 140, and the extrusion between the materials and the side wall of the casing 141 cannot occur, so that the blockage is not easy to occur. In addition, when the material shifting blade 1422 is in an open state, the material can directly fall from the feeding port 1412 of the housing 141, so that the material can be discharged smoothly, and the pressure on the material shifting blade 1422 and the rotating shaft 1421 can be reduced by the direct falling of the material, so that the tank 110 with a larger adaptive volume can be adapted.

In addition, since the more the material ejecting blades 1422 on the rotating shaft 1421 are, the narrower the area through which the material can pass when the discharging passage 144 is opened to the maximum extent, the fewer the material ejecting blades 1422 are provided, the faster the material falls when the door is opened, and the higher the discharging efficiency. In view of the above, the shaft 1421 is preferably provided with five material ejecting blades 1422.
