Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
Referring to fig. 1 and 2, the present solution provides a blanking device, where the blanking device includes a storage bin 1, an activation bin 2 connected to the lower end of the storage bin 1, and a blanking tube 3 connected to the center of the lower end of the activation bin 2, a first bar valve 4 located at the upper end, a kick-out device 6 located at the lower side of the first bar valve 4, and a kick-out screw 9 are disposed in the activation bin 2, where the kick-out device 6 can kick-out material from the center of the activation bin 2 along a horizontal first direction, and the kick-out screw 9 can push material from the center of the activation bin 2 along a horizontal second direction perpendicular to the first direction.
The conical storage bin 1 can store a certain amount of materials, the lower end of the conical storage bin is connected with the activation bin 2 with a rectangular cross section, the materials can be conveyed to the blanking pipe 3 through the activation bin 2, and the materials are further discharged through the blanking pipe 3.
The through flow area of the activation bin 2 is between the storage bin 1 and the blanking pipe 3, and the material can be prevented from arching at the bottom of the storage bin 1 by being used as a transition between the storage bin 1 and the blanking pipe 3, so that the storage bin 1 with a larger through flow area is prevented from being directly connected to the blanking pipe 3 with a smaller area. "arching" in this scheme means that the material is compacted to form an arch structure, resulting in the inability of the material to continue to fall.
In addition, the material shifter 6 and the material pushing screw in the activation bin 2 are used for activating and pushing materials so as to avoid hardening and arching of the materials.
Wherein, the material ware 6 can stir the material to central point along first direction, and the pushing away material spiral 9 promotes the material to central point along the second direction, and in this process, the material ware 6 and the pushing away material spiral 9 can make the broken of hardened material, avoid the material hardening.
The first bar valve 4 may close the activation bin 2 such that the activation bin 2 no longer receives material from the storage bin 1, avoiding that falling material forms an arched compaction structure in the upper part of the activation bin 2.
In normal operation, the first bar valve 4 is in an open condition to allow material to fall into the activation bin 2; when the components in the activation bin 2 fail and need to be overhauled, the first bar valve 4 can be inserted into the activation bin 2 first, so that materials are prevented from falling into the activation bin 2 further, after overhauling is finished, the material stirring device 6 and the material pushing screw 9 are started, so that the materials are crushed and forcedly move towards the central position of the activation bin 2 to fall into the blanking pipe 3 connected to the center.
During operation, the ejector 6 and the pusher screw 9 can be operated at intervals for a period of time, avoiding arching of the material in the activation bin 2.
Wherein the ejector 6 comprises an ejector lever 8 extending in the second direction and rotatable about a central axis in the second direction. Referring to fig. 1, the deflector rod 8 extends in a second horizontal direction and rotates about a central axis in the second direction, which during rotation, deflects material towards a central position and may act to break up arch-shaped compacted material.
Further, the material shifter 6 includes two material shifting rods 8, and the material shifting rods 8 are respectively staggered in the axial direction and the circumferential direction. In the embodiment shown in fig. 1, two stirring rods 8 are provided, which are respectively located at the upper side and the lower side, and are circumferentially staggered by 180 degrees, and in the rotating process, the two stirring rods 8 can stir and stir materials at different positions. The shifter 6 may include a rotation shaft at a central axis, a support rod 14 connected to the rotation shaft, and the shifter lever 8 connected to the support rod 14.
In addition, a plurality of poking teeth are arranged on the poking rod 8. The poking teeth can play a role in crushing materials, and a plurality of poking teeth which are axially arranged at intervals can be arranged on each poking rod 8.
Furthermore, the cross section of the deflector rod 8 may be wedge-shaped, the pointed direction of which corresponds to the direction of rotation of the deflector rod 8, so that the material may be broken by the pointed direction.
In addition, the bottom of the activation bin 2 is provided with a circular arc groove matched with the pushing spiral 9. Referring to fig. 2, the bottom of the activation bin 2 is recessed downwards to form a circular arc groove, the inner diameter of the circular arc groove is matched with the outer diameter of a spiral blade of the pushing spiral 9, and when the spiral blade rotates, the spiral blade can push materials in the circular arc groove to move towards the center. It can be seen that the circular arc shaped grooves can limit the lateral movement of the material but to the centre along the axial direction of the helical blade.
Wherein the blanking device comprises two material kickers 6 arranged on two sides of the center of the activation bin 2 along the first direction and/or two material pushing spirals 9 arranged on two sides of the center of the activation bin 2 along the second direction. Referring to fig. 1 and 2, two kickers 6 can kick material from both sides in a first direction toward the center, and two pusher screws 9 push material from both sides in a second direction toward the center. The tripper 6 may include a drive motor or other drive member as may a similar ejector screw 9. When the blanking device is in operation, the two lifters 6 and the two pushing screws 9 can be operated alternately, respectively, in order to avoid arching in the activation bin 2.
In addition, two decompression plates 5 are provided in the activation bin 2 on the upper side of the kick-out device 6, the two decompression plates 5 are located on both sides of the activation bin 2 in the first direction, and the lower ends of the two decompression plates 5 are inclined toward each other to block out a part of the two kick-out devices 6, respectively. Referring to fig. 2, two pressure reducing plates 5 are arranged at intervals along the first direction, and the pressure reducing plates 5 shield a part of the material shifter 6, namely, a part of the space occupied by the material shifter 8 when rotating, so that the material does not fall on the shielded part, on one hand, the impact force on the material shifter 6 is reduced, and on the other hand, the lower side of the pressure reducing plates 5 does not accumulate the material (or accumulates little material), and the starting resistance of the material shifter 6 is reduced. The upper surface of the pressure reducing plate 5 can be provided with a high polymer plate (polytetrafluoroethylene plate or high polymer polyethylene plate) capable of reducing the friction force of materials, so that the friction force with the materials can be reduced, and the materials can slide off on the pressure reducing plate 5 more easily. In addition, the activation bin 2 is provided with an observation window 10, and the internal condition can be observed through the observation window 10 so as to judge whether the materials in the activation bin are in a blocking state or not.
Wherein, the activation bin 2 is provided with a pressure-bearing cone 11 positioned at the center of the activation bin, and the height of the pressure-bearing cone 11 is higher than that of the pushing screw 9. The pressure-bearing cone 11 is positioned right above the blanking pipe 3, and can bear the falling materials through the tapered structure, so that the materials are prevented from being compacted due to the fact that the materials directly fall into the blanking pipe 3.
In addition, a second bar valve 12 is arranged at the upper end of the blanking pipe 3; and/or, a rotor level gauge 13 is arranged on the blanking pipe 3. In normal use, the majority of the length of the second bar valve 12 is withdrawn from the blanking tube 3, leaving only a small portion of the length inside the blanking tube 3, for example 1/5 of the length, which to some extent can contain a small amount of material, avoiding compaction of the material in the lower part of the blanking tube 3 and avoiding clogging. The rotor level gauge 13 can monitor the material level in the blanking pipe 3 to determine whether the material therein is in a stacked state, for example, when the equipment connected to the blanking pipe 3 stops conveying the material, the material will be stacked in the blanking pipe 3, and the rotor level gauge 13 monitors the rising of the material level, and at this time, the operation of the dialer 6 and the pushing screw 9 should be stopped.
Furthermore, a vibrator 7 is arranged on the storage bin 1 and the blanking pipe 3 respectively. The rappers 7 may be arranged in plurality at intervals in the circumferential direction of the storage bin 1; the rapper on the blanking tube 3 is not marked. The rapper 7 is adapted to vibrate and strike the storage bin 1 and the blanking tube 3 in order to facilitate the downward flow of material therein, in particular, when arching occurs therein, the arching can be eliminated by rapping.
