Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In which like parts are designated by like reference numerals.

A storage tank 100, as shown in fig. 1 and 2, includes a tank body 110 and a sleeve 120 fixedly disposed within the tank body 110. The top of the tank body 110 is provided with a feed inlet, and the bottom of the tank body 110 is provided with a discharge outlet. The number of the sleeves 120 is two or more, in this embodiment, two sleeves 120 are provided, and the diameters of the sleeves 120 are different, wherein the sleeve 120 with a larger diameter is sleeved outside the sleeve 120 with a smaller diameter, all the sleeves 120 are coaxial with the tank 110, and the sleeve 120 divides the area inside the tank 110 into annular areas in a layer. A gap is reserved between the top of the sleeve 120 and the top wall of the tank body 110, so that the feed inlet of the tank body 110 can be communicated with the space in each layer of sleeve 120, and a gap is reserved between the bottom of the sleeve 120 and the bottom wall of the tank body 110, so that the discharge outlet of the tank body 110 can be communicated with the space in each layer of sleeve 120. The projection of the feed inlet of the storage tank 100 in the axial direction of the casing 120 falls into the projection of the casing 120 with the smallest diameter in the axial direction, so that the material entering from the feed inlet falls into the casing 120 with the smallest diameter, i.e. the innermost casing, preferentially. 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 the 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 that fills up in later stage increase, 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, make the material mixing of large granule and small granule in the storage tank 100 relatively even, especially be fit for the material loading of the powder of similar cake powder wherein the particle size is uneven like this.

As shown in FIG. 1, 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. As shown in fig. 2, the number of the support rib plates 130 in each layer is the same, and the projections of the support rib plates 130 in each layer in the axial direction of the tank 110 are overlapped with each other, so as to minimize the obstruction of the support rib plates 130 to the blanking. 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.

As shown in fig. 1, the bottom wall of the tank 110 is preferably provided with a conical structure, and the discharge hole of the tank 110 is located at the vertex of the cone, so that the material is concentrated towards the discharge hole. The bottom of each sleeve pipe 120 is the parallel and level, and the material in each region in jar body 110 can fall in step when the ejection of compact like this, and the ejection of compact is in the same place in the material mixing in each region, collects the material granule by the toper diapire, will concentrate to the centre to the rolling great particulate matter material of limit portion, forms the compounding, more helps the unloading even.

The preferred holding tank 100 further comprises a discharger 140, as shown in FIG. 1, and the preferred holding tank 100 further comprises a discharger 140, as shown in FIG. 1, the discharger 140 being disposed below the tank body 110. As shown in fig. 3 and 4, 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. 4, 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 larger than the distance between the two rotating shafts or smaller 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. 5, 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 gap 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. Compare in traditional single rotor tripper, two of this tripper are dialled material rotor 142 and are located outside-in at the feed inlet of shell and rotate, make the material by dialling material rotor 142 and dial to in the middle of tripper 140, have solved its material and have been dialled to the shell 141 wall of tripper 140 by the rotor, cause material and shell 141 extrusion easily, increase rotor rotation resistance, when the shell 141 interior material is more, cause obstructed technical problem easily. 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.

The two material-ejecting rotors 142 are preferably identical in structure, which facilitates the ease of manufacture and assembly, on the one hand, and the balance of the forces applied to the two material-ejecting rotors 142, on the other hand. The housing 141 is preferably configured as a rectangular shell that facilitates processing and installation of the kick-off rotor 142. The kick-out blades 1422 are preferably rectangular sheets, on one hand, because the rectangular shape is simple and convenient to process; the other side is that when the blade is rectangular, the joint of the two material shifting blades 1422 of the closed discharging channel 144 is a straight line, and compared with blades of other shapes, the straight line of the joint is the shortest, which is more convenient to ensure the installation accuracy. In the structure of this embodiment, the two material ejecting rotors 142 have the same specification, the casing 141 is a rectangular body, the material ejecting blade 1422 is a rectangular plate, the width direction of the material ejecting blade 1422 is radially arranged along the rotating shaft 1421, the length direction of the material ejecting blade 1422 is parallel to the axis of the rotating shaft 1421, the rotating shaft 1421 is horizontally arranged and rotatably connected in the casing 141, the axial distance H1 between the two material ejecting rotors 142 is twice the width of the material ejecting blade 1422, and the two material ejecting rotors 142 are preferably in clearance fit to avoid collision between the material ejecting blades 1422 of the two material ejecting rotors 142, as shown in fig. 4, the distance H2 between the left and right side walls of the casing 141 is twice the diameter of the material ejecting rotors 142, and the front, rear, left and right side walls of the casing 141 and the material ejecting blade 1422 are preferably in clearance fit to avoid collision between the material ejecting blades 1422 and the casing 141. The rotating shaft 1421 is preferably provided with more than four material shifting blades 1422, so that no matter what angle the material shifting rotor 142 rotates, at least one material shifting blade 1422 is always in a horizontal posture or a posture that the free end is inclined upwards between the left (right) side wall and the left (right) side rotating shaft 1421 of the housing 141, so that the material falling between the left (right) side wall and the left (right) side rotating shaft 1421 of the housing 141 can be supported by the material shifting blade 1422 in the upward inclined or horizontal posture, the material can stay on the material shifting blade 1422 or move towards the rotating shaft 1421 under the action of gravity, and even if the horizontal projection of the material inlet 1412 exceeds the range of the material discharging channel 144, the material can be reduced or prevented from falling from the area outside the material discharging channel 144, which is beneficial to increasing the material inlet and improving the material discharging efficiency; when the rotating shaft 1421 is provided with four material shifting blades 1422, there is only one horizontal material shifting blade 1422 between the side wall of the housing 141 and the adjacent rotating shaft 1421, and since the material shifting blades 1422 are in a horizontal state and the material thereon is piled up, the material may fall from the free end of the material shifting blade 1422 along the slope of the material pile, so that it is better to set more than five blades. 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. The top of the housing 141 can be set to be in a non-top open form, and the top opening is a feed inlet of the housing 141, so that the structure is convenient to process and mount the material poking rotor 142, and the range of the feed inlet 1412 is large, so that the material poking blades 1422 can be in contact with materials more quickly and sufficiently, and the feeding efficiency is improved; in addition, the material can be prevented from being extruded with the top wall of the shell 141 by the feeding hole, and the rotation resistance of the material stirring rotor 142 can be reduced. It should be noted that when the structure that the horizontal projection of the material inlet is beyond the range of the material discharging channel 144 is adopted, especially when the structure that the top of the shell 141 is opened as the material inlet of the shell 141 is adopted, as shown in fig. 1, the bottom wall of the conical structure of the tank body 110 is matched, so that the material entering the material inlet is gathered towards the middle under the guidance of the inclined surface of the conical structure, the material is gathered towards the material discharging channel 144, and the material passing through the outer area of the material discharging channel 144 is avoided or reduced. The open form in bottomless can be established to shell 141's bottom, and the open discharge gate that is shell 141 in bottom, the simple structure of shell like this, and the hindrance to the material unloading is few, the unloading of being convenient for. In order to facilitate the connection of the discharger 140 with the tank 110 above the discharger and the receiving device below the discharger, connecting flanges 1411 may be fixedly disposed at the top and bottom edges of the casing 141, so that the discharger 140 is connected with other devices through bolts.

Of course, the two material-ejecting rotors 142 may be driven by a single driver 143 by a transmission mechanism such as a chain transmission mechanism or a gear transmission mechanism. It should be noted that the above-mentioned clearance fit in this application means that two objects in cooperation can relatively move and do not collide with each other during the relative movement, and no material or a small amount of material is allowed to leak out between the two objects in cooperation.

The specific examples are merely illustrative of the utility model and are not intended to be limiting.
