Description

Powder particle production, generally have mechanical crushing, fluid atomization crushing, spray drying, chemical precipitation, extrusion and cutting and other ways. In the particle morphology, the morphology of the powder particles produced by different methods is significantly different. In the particle size range, in addition to the relatively uniform particles obtained by extrusion and cutting, the particle size distribution of the particles obtained by the remaining methods is relatively wide.

Generally, a plug valve or a flap valve is matched with the discharge port to control the opening and closing of the discharge port. During the discharging, the plug valve / flap valve is controlled to be opened, and the material in the hopper flows out from the discharge port due to gravity, and when the amount of discharge is sufficient, the valve is closed.

[0004] However, in actual production, the fine powder in the discharging stage often appears to be agglomerated and bridged, which is easy to block the discharge port, resulting in poor discharging. At this time, manual intervention is usually required, that is, a long rod is used to lightly push the discharge port, or the hopper is hit lightly or heavily to destroy the agglomeration and bridging near the discharge port by vibration. On the other hand, when the discharging is smooth, a large amount of powder will flow out from the discharge port in a few seconds, and it is impossible to balance and stably send the powder to the next process. If a large amount of high-quality powder (commonly used in metal powder) is poured onto the screen at one time, not only the powder cannot be efficiently screened, but also the screen is easily damaged, resulting in screening failure. Therefore, it is urgent to design a hopper structure with controllable discharging amount. UTILITY MODEL CONTENTS

[0031] The embodiments of the present application will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0032] As Figures 1-2 shown, the embodiment provides a hopper structure, which comprises a hopper body 1, a support 2, a driving member 3, a blocking member 4 and a controller. The hopper body 1 has a feeding port 11, a containing cavity 12 and a discharging port 13 which are sequentially communicated; the support 2 is arranged on the hopper body 1 and located at the feeding port 11; the driving member 3 is located in the containing cavity 12, one end of the driving member 3 is connected with the support 2; the blocking member 4 is located in the containing cavity 12, the other end of the driving member 3 is drivingly connected with the blocking member 4, the driving member 3 drives the blocking member 4 to move so as to block or avoid the discharging port 13, the blocking member 4 can adjust the opening degree of the discharging port 13; the controller is electrically connected with the driving member 3, and the controller controls the working of the driving member 3.

[0033] The hopper structure provided by the utility model can drive the blocking member 4 to move through the driving member 3, so that the blocking member 4 blocks or avoids the discharging port 13, and the controller and the driving member 3 are electrically connected, so that when the hopper structure discharges, the discharging port 13 is first placed at a specified position, the valve of the discharging port 13 is opened, the driving member 3 is started, the driving member 3 drives the blocking member 4 to move, that is, the up-down reciprocating movement of the blocking member 4 is realized, the output parameters of the driving member 3 are controlled and adjusted by the controller, so that the up-down movement amplitude and frequency of the blocking member 4 can be adjusted, the opening degree of the discharging port 13 is controlled, and the discharging amount of the discharging port 13 is accurately controlled.

[0034] It should be noted that due to the differences in particle size range, bulk density and the like of the powder and granular material, the driving member 3 has different parameters such as output force, output frequency and Z-axis direction movement distance, which are adjusted according to specific scenes.

[0035] In some embodiments, the blocking member 4 comprises a connecting rod 41 and a blocking head 42. One end of the connecting rod 41 is detachably connected with the other end of the driving member 3, and the other end of the connecting rod 41 is connected with the blocking head 42. In this way, the driving member 3 drives the connecting rod 41 to move, and the connecting rod 41 drives the blocking head 42 to move, so as to achieve the purpose of blocking or avoiding the discharging port 13 by the blocking head 42. When the hopper is fed, only the connecting rod 41 and the blocking head 42 are placed at the bottom of the containing cavity 12. Since the bottom of the hopper body 1 is conical, the blocking head 42 has a self-weight and a gravity center that is lower, so that the feeding is very stable and will not be overturned.

[0036] Optionally, the blocking head 42 is a hollow structure made of metal, which is mainly used to save the output power of the driving member 3.

[0037] Optionally, the other end of the connecting rod 41 and the blocking head 42 are connected by welding.

[0038] In the embodiment, in order to better adjust the opening size of the discharge port 13, the sealing head 42 comprises a tapered section and an arc section connected with each other, the tapered section is connected with the connecting rod 41, and the arc section has an arc sealing surface, wherein the arc sealing surface faces the discharge port 13, and the arc sealing surface can effectively seal or avoid the discharge port 13. When the sealing head 42 moves upward, a large annular space is formed between the arc sealing surface and the discharge port 13 for powder discharging; when the sealing head 42 moves downward, the annular space is reduced or the discharge port 13 is directly blocked, so that the powder discharging is reduced or stopped. At the same time, when the sealing head 42 moves upward and downward, continuous vibration is brought to the vicinity of the discharge port 13, the agglomeration and bridging are improved, and then the powder discharging is stable.

[0039] Specifically, the sealing member 4 further comprises an elastic protective sleeve 43, and the elastic protective sleeve 43 is wrapped around the arc sealing surface, so that when the elastic protective sleeve 43 abuts against the inner wall of the containing cavity 12, the elastic protective sleeve 43 can play a buffering role, and at the same time, an elastic deformation space is formed, which is more conducive to keeping the position of the sealing member 4 stable.

[0040] Optionally, the material of the elastic protective sleeve 43 is rubber or silicone.

[0041] In the embodiment, the hopper structure further comprises a first connecting member 5 and an elastic pad 52. The elastic pad 52 is arranged between the driving member 3 and the sealing member 4, and the driving member 3 is connected with the sealing member 4 through the first connecting member 5. In this way, when the sealing member 4 moves, the elastic pad 52 provides an elastic deformation space for the upper part of the sealing member 4 during movement, so as to alleviate the phenomenon that the sealing member 4 moves unstably due to uneven flow of the powder in the hopper during movement.

[0042] Optionally, the material of the elastic pad 52 is rubber or silicone.

[0043] Specifically, the first connecting member 5 comprises a first flange clamp 51 and a first fastener, the driving member 3 and the sealing member 4 can be sleeved by the first flange clamp 51, and the driving member 3 and the sealing member 4 are locked by the first fastener, so as to realize the connection between the driving member 3 and the sealing member 4.

[0044] As Figure 1As shown, in the embodiment, the support 2 comprises a support rod 21, a first hook 22 and a second hook 23. The support rod 21 is arranged on the hopper body 1 and located at the feeding port 11, and the first hook 22 and the second hook 23 are both hinged with the hopper body 1, so as to facilitate the rotation of the first hook 22 and the second hook 23, wherein the first hook 22 and the second hook 23 are respectively located at two ends of the support rod 21, and the arrangement can hook the two ends of the support rod 21 through the first hook 22 and the second hook 23 respectively, so as to ensure the stability of the support rod 21. Specifically, one end of the driving member 3 is detachably connected with the support 2. In this way, the installation and disassembly of the driving member 3 are facilitated.

[0045] Specifically, the two ends of the support rod 21 are respectively provided with a first limiting head 211 and a second limiting head 212, wherein the first limiting head 211 is capable of limiting cooperation with the first hook 22, and the second limiting head 212 is capable of limiting cooperation with the second hook 23. In this way, the first hook 22 and the second hook 23 can be prevented from being separated from the support rod 21.

[0046] In the embodiment, the driving member 3 comprises, but is not limited to, a driving cylinder or a driving electric cylinder or a hydraulic cylinder. The purpose is to drive the blocking member 4 to move through the driving member 3.

[0047] Specifically, the hopper structure further comprises a bearing frame 6 and a plurality of universal wheels 7. The hopper body 1 is arranged on the bearing frame 6, and the plurality of universal wheels 7 are arranged at the bottom of the bearing frame 6 at intervals. In this way, the bearing frame 6 can be pushed, so that the hopper body 1 reaches the designated position.

[0048] It should be noted that in the application scenario where the hopper body 1 still has material and needs to be immediately stopped, we generally adopt the mode of directly closing the gate valve and the flap valve. At this time, the powder is still continuously flowing out, and forcibly closing the valve usually causes a large amount of powder to enter the valve chamber of the gate valve, resulting in closing failure or long-term residual powder in the valve chamber, causing the valve chamber to deform and making the opening and closing not smooth or even difficult. When the discharge port 13 is a flap valve, the edge of the flap will be worn, and the powder will leak for a long time. At this time, if the blocking head 42 can temporarily control the powder, and then the valve is closed, the above-mentioned situation can be avoided to a certain extent, thereby prolonging the service life of the valve.

[0049] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
