Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. Wherein like parts are designated by like reference numerals and are described with reference to the position shown in fig. 1 as an example. In the present application, the term "clearance fit" refers to a relative displacement between two objects that are matched with each other and no collision occurs during the relative displacement, and no material or a small amount of material is allowed to leak out between the two objects that are matched with each other.

A magazine, as shown in fig. 1, includes a magazine 110 and an unloader 140. The top of the storage container 110 is provided with a feeding hole, and the bottom of the storage container 110 is provided with a discharging hole. The discharger, as shown in fig. 2 and 3, includes a housing 141, a setting rotor 142 disposed in the housing 141, and a driver 143 for driving the setting rotor 142 to rotate. The top of the shell 141 is provided with a feeding port 1412, the feeding port 1412 is communicated with the discharging port of the storage container 110, and the bottom of the shell 141 is provided with a discharging port 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. 2, 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 discharging 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 size of a 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 consistent with the size of a rectangular plane obtained by intersecting the shell, and the material shifting rotors can move. For another example, as shown in fig. 4, 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 sidewalls 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 likelihood of material flowing out of the tripper 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 material inlet to the material outlet, thus, when the two material ejecting rotors 142 rotate, the two material ejecting blades 1422 in the discharging channel 144 are switched between the two states of being in the same plane and not 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 plectrum blades 1422 in the discharge channel 144 are not in the same plane, the plectrum blades 1422 will no longer close the discharge channel 144, material can pass through the channel between the two plectrum blades 1422, thus, the material stirring rotor 142 continuously rotates to make the discharging channel 144 assume two different states of 'door open' and 'door closed' periodically, when the door is opened, the material is discharged, and when the door is closed, the material is supported by the material shifting blade 1422 to close the discharger. Compared with the traditional single-rotor discharger, the discharger with the structure has the advantages that the two material stirring rotors 142 rotate from outside to inside at the material inlet, so that materials are stirred to the middle of the discharger by the material stirring rotors 142, the technical problem that the materials are extruded with the shell 141 and the rotation resistance of the rotors is increased easily because the materials are stirred to the wall of the shell 141 of the discharger by the rotors, and the blockage is easily caused when more materials are in the shell 141 is solved. In addition, when the discharger with the structure of the invention discharges materials, the two material stirring rotors 142 positioned at the side of the material inlet rotate oppositely and concentrate the materials from two sides to the middle, when the materials are displaced along with the material stirring blades 1422, the materials can be upwards extruded to occupy the space on the upper part of the shell 141141 or in the material storage device above the discharger, and the extrusion between the materials and the side wall of the shell 141 can not occur, so 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 material storage container 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 material shifting blades 1422 are preferably rectangular sheets, on one hand, the rectangular shape is simple and convenient to process, and on the other hand, when the blades are rectangular, the joint of the two material shifting blades 1422 of the closed discharging channel 144 is a straight line, and compared with the blades of other shapes, the straight line of the joint is shortest, so that the installation precision is more convenient to ensure. In the structure of this embodiment, the specifications of the two material ejecting rotors 142 are the same, the casing 141 is a rectangular body, the material ejecting blades 1422 are rectangular plates, the width direction of the material ejecting blades 1422 is radially arranged along the rotating shaft 1421, the length direction of the material ejecting blades 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 blades 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 the figure, 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 clearance fit between the front, rear, left and right side walls of the casing 141 and the material ejecting blades 1422 is 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 with a free end inclined upwards between the left/right side wall of the housing 141 and the left/right rotating shaft 1421, and thus the material falling between the left/right side wall of the housing 141 and the left/right rotating shaft 1421 can be supported by the material shifting blade 1422 in the upward inclined or horizontal posture, and the material can stay on the material shifting blade 1422 or move towards the rotating shaft 1421 under the action of gravity, so that 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, and the material inlet can be increased, and the material discharging efficiency can be improved; 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 feeding port of the housing 141, so that the structure is convenient to process and mount the material shifting rotor 142, and the range of the feeding port 1412 is large, so that the material shifting 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 port, 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 exceeds the range of the material discharging channel 144 is adopted, especially when the structure that the top of the housing 141 is open as the material inlet of the housing 141 is adopted, as shown in fig. 3, the material storage container 110 used in cooperation with the material discharger in the material storage device is preferably provided with a funnel-shaped material discharging hopper 111, the material discharging port of the material storage container and the tip end of the material discharging hopper 111 are communicated with the material inlet through the material discharging hopper 111, and the central line of the material inlet is coincident with the central line of the material discharging hopper 111, so that the material entering from the material inlet will converge towards the middle under the guidance of the inclined plane of the material discharging hopper 111, which helps to concentrate the material towards the material discharging channel 144, thereby helping to prevent or reduce the material from passing through the area outside the material discharging channel 144. The open form in bottomless can be established to shell 141's bottom, and the uncovered discharge opening that is shell 141 in bottom, and the simple structure of shell like this hinders few to the material unloading, the unloading of being convenient for. In order to facilitate the connection of the discharger with the above storage device and the below receiving device, the connecting flanges 1411 may be fixedly arranged at the top and bottom edges of the casing 141, so that the discharger is connected with other devices through bolts.

In order to control the amount of material to be discharged, the driver 143 is preferably an adjustable speed motor, and preferably, the two material ejecting rotors 142 are driven by the two drivers 143, so that the rotating speeds of the two material ejecting rotors 142 can be controlled individually and precisely, and when one rotor or the driver 143 has a problem, the other material ejecting rotor 142 and the corresponding driver 143 can also function. 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.

As shown in fig. 5 and 6, a casing 120 is preferably disposed in the magazine 110. 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 the larger diameter is sleeved outside the sleeve 120 with the smaller diameter, all the sleeves 120 are coaxial with the storage container 110, and the sleeve 120 divides the area in the storage container 110 into annular areas in a layer. A gap is reserved between the top of the casing 120 and the top wall of the storage container 110, so that the feeding hole of the storage container 110 can be communicated with the space in each layer of the casing 120, and a gap is reserved between the bottom of the casing 120 and the bottom wall of the storage container 110, so that the discharging hole of the storage container 110 can be communicated with the space in each layer of the casing 120. The axial projection of the inlet of the storage container 110 on the casing 120 falls into the axial projection of the casing 120 with the smallest diameter, so that the material entering from the 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 material storage device, the material enters the casing 120 with the smallest diameter first, and when the casing 120 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 material storage container 110 and the casing 120 with the largest diameter, so that the whole material storage container 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. The distance between the top of each sleeve 120 and the top wall of the storage container 110 is set to be equal distance d, so that materials are constrained by the sleeves 120, only after the sleeve 120 with the smallest diameter is filled, a small material stack can be formed in the height range of d, and the sleeve 120 which is filled in later period is increased, the material stack can be gradually gentle, the phenomenon that the large part of particles in the materials rolls down from the large material stack is reduced, the segregation of powder is greatly reduced, the large particles and the small particles in the storage container 110 are mixed relatively uniformly, and the device is particularly suitable for loading the powder which is similar to cake powder and has uneven particle size.

As shown in fig. 5, the distance d between the top of the casing 120 and the top wall of the storage container 110 is preferably set to be between 800mm and 1000mm in order to ensure that the material has enough space to overflow to the outermost region. Preferably, the distance a between the wall of the storage container 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 width of each layer in the storage container 110 is the same, so that the states of the materials entering the layer areas are relatively close, the uniformity of the materials in the layer areas is similar, and the uniformity of the material in the storage container 110 is relatively good. The storage container 110 may be any tank structure such as circular, rectangular, etc., but it is desirable that the cross-sectional shape of the casing 120 is the same as the cross-sectional shape of the storage container 110, wherein circular is preferable, so that no sharp corner is formed on the wall of the casing 120 and the wall of the tank, which facilitates uniform outward overflow of the material.

The casing 120 with the largest diameter is connected with the tank wall of the storage container 110 through a support rib plate 130, and two adjacent casings 120 are also connected through the support rib plate 130, so that each casing 120 is vertically suspended in the storage container 110. The plurality of rib support plates 130 are arranged along the radial direction of the storage container 110, and the rib support plates 130 are arranged along the axial direction of the storage container 110 in one or more layers, in this embodiment, an upper layer, a middle layer and a lower layer of rib support plates 130 are arranged to ensure the stability of each casing 120. As shown in fig. 6, the number of support webs 130 per layer is the same, and the projections of the support webs 130 of the layers in the axial direction of the storage container 110 are overlapped with each other, so as to minimize the obstruction of the support webs 130 to the blanking. In order to stabilize the center of gravity of the storage device and to distribute the materials uniformly, the supporting rib plates 130 in the same layer are preferably distributed radially around the axis of the storage container 110, and in this embodiment, four supporting rib plates 130 are provided at each layer.

As shown in fig. 5, the bottom of each sleeve 120 is flush, so that the materials in each area in the material storage container 110 can fall synchronously during discharging, the materials in each area are mixed together to be discharged, the material particles are collected by the conical bottom wall, and the larger particulate materials rolling towards the edge are concentrated towards the middle to form a mixed material, which is more beneficial to uniform discharging.

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