Description

Technical Field

[0001] This application belongs to the field of silo anti-clogging technology, specifically a silo and anti-clogging device. Background Technology

[0002] Silos are essential equipment for storing bulk materials, widely used for storing raw materials, intermediate products, finished products, additives, and other materials. Their primary function is to provide stable and reliable material storage solutions for industrial production, ensuring the continuity and efficiency of the production process. Silo equipment is scientifically designed and structurally sound, capable of meeting the storage needs of various materials, playing an indispensable role, especially in the storage, transportation, and distribution of bulk materials.

[0003] During the material discharge process from the silo, the humidity, temperature, and compaction degree of the material within the silo all affect particle interaction, leading to material agglomeration. Material agglomeration is a significant contributing factor to bridging. Therefore, as material flows out of the silo, it is subject to gravity and the interaction between material particles. Under certain circumstances, factors such as friction and electrostatic forces between material particles can exceed the effects of gravity, causing the material to form arch-like structures within the silo, the so-called bridging phenomenon. This phenomenon affects the normal flow of material, leading to poor discharge or blockages, severely impacting production efficiency.

[0004] The existing solution is to manually poke the material at the bottom of the silo cone. This method requires frequent manual operation, which is very wasteful of manpower and inefficient. Another method is to add a vibrator at the silo, but the vibrator can only act on the silo wall and is difficult to effectively transmit to the inside of the material. It is not effective in dealing with deep agglomeration or severe bridging problems. Utility Model Content

[0005] The purpose of this application is to solve the above-mentioned problems and provide a silo anti-clogging device. This device uses a drive unit to drive a shaft to reciprocate, causing a dispersing component to oscillate along a fan-shaped trajectory within the housing. The silo discharges material through a feed pipe and through the housing. The material falling along the feed pipe is dispersed by the oscillation of the dispersing component, solving the problem of bridging caused by agglomeration during discharge, which affects the smooth flow of material or causes blockage. This application also provides a silo equipped with this device.

The end of the first shaft is provided with a drive gear, and the ends of the second and third shafts are both provided with driven gears.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Before describing the implementation of this application, it should be noted that the silo anti-blocking device of this application is located at the discharge pipe of the silo cone. Because the silo cone is a highly fluid area, that is, when the silo discharges, the material in the silo is still in a flowing state. The purpose of this device is to break up the clumps of material in the silo during the discharge process, thereby ensuring the smoothness of the discharge.

[0028] Example 1

[0029] refer to Figures 1-6 A silo anti-clogging device includes a housing 1, which is disposed in the feed pipe of silo a. A shaft 2 is rotatably connected inside the housing 1. The shaft 2 is located in the middle of the housing 1. A plurality of dispersing elements 24 for dispersing materials are provided along the length of the shaft 2. A drive unit 13 is provided at one end of the housing 1. The drive unit 13 is connected to the shaft 2 for transmission. The drive unit 13 is used to drive the shaft 2 to reciprocate and rotate, so that the dispersing elements 24 swing along a fan-shaped trajectory inside the housing 1. The dispersing elements 24 are used to disperse the materials falling along the feed pipe.

[0030] This device can be installed in conjunction with the silo body a or other storage containers. Specifically, the discharge pipes of silo body a are installed at the top and bottom of the housing 1, so that the housing 1 is as close as possible to the bottom of the conical part of silo body a. Overall, the housing 1 is set in the discharge pipe of the silo. The specific connection method can be welding or bolting. Implicitly, the housing 1 is provided with an inlet 11 and an outlet 12. The material output from silo body a will pass through the housing 1 along the discharge pipe and then be conveyed downwards.

[0031] In this design, when the hopper discharges material, the material is released through the discharge pipe and passes through the housing 1. The device drives the shaft 2 to rotate back and forth through the drive unit 13, causing the dispersing component 24 to swing along a fan-shaped trajectory inside the housing 1, breaking up the material falling along the discharge pipe. The broken material is then discharged through the discharge pipe at the bottom of the housing 1. This not only increases the fluidity of the material, but also solves the problem of bridging caused by agglomeration during discharge, which affects the smooth discharge or causes blockage.

[0032] Preferably, in the projection of the vertical plane, the central angle of the fan-shaped trajectory formed by the swing of the dispersing member 24 is directed toward the feed inlet 11, and the central angle is greater than or equal to 180°.

[0033] It should be noted that the orientation of the central angle described in this embodiment is actually the direction of the axis of symmetry of the formed fan-shaped trajectory. That is, in the projection of the vertical plane, the axis of symmetry of the formed fan-shaped trajectory does not intersect with the side wall of the housing 1, and this axis of symmetry can pass through the feed inlet 11. Furthermore, the central angle is greater than or equal to 180°. Combined with the orientation of the central angle, this ensures that the swing angle of the dispersing member 24 can cover most of the area, resulting in a better dispersing effect.

[0034] In this embodiment, there are multiple shafts 2, and the ends of two adjacent shafts 2 are connected by a transmission. The drive unit 13 is connected to one of the shafts 2 and is used to drive the shaft 2 connected to it to reciprocate, so as to drive multiple shafts 2 to reciprocate.

[0035] Specifically, the drive unit 13 drives one of the shafts 2 to reciprocate. When two adjacent shafts 2 are connected by transmission, the reciprocating rotation of the shaft 2 will also drive the other shafts 2 to reciprocate. This enables one drive unit 13 to synchronously drive multiple shafts 2 to reciprocate, so that the dispersion parts 24 on the multiple shafts 2 swing synchronously in the housing 1, thereby improving the dispersion effect.

[0036] In this embodiment, there are three shafts 2, namely a first shaft 21, a second shaft 22, and a third shaft 23. The end of the first shaft 21 is provided with a drive gear 221, and the ends of the second shaft 22 and the third shaft 23 are both provided with driven gears 25. The drive gear 221 and the driven gear 25 are both located outside the housing 1. The first shaft 21, the second shaft 22, and the third shaft 23 mesh and drive in sequence, or the second shaft 22 and the third shaft 23 are arranged on both sides of the first shaft 21 and mesh and drive in the first shaft 21. The drive unit 13 drives the drive gear 221 to rotate back and forth in a rotary drive or linear reciprocating drive manner.

[0037] In a preferred embodiment, the second shaft 22 and the third shaft 23 are arranged on both sides of the first shaft 21 and mesh with the first shaft 21 for transmission; in other embodiments, the first shaft 21, the second shaft 22 and the third shaft 23 mesh with each other for transmission. Both methods can realize the synchronous reciprocating rotation of the first shaft 21, the second shaft 22 and the third shaft 23 by a single drive unit 13. The operator can choose to use the first method or the second method according to the actual situation; and this embodiment adopts the first method based on the premise of space utilization.

[0038] Regarding the driving method of the drive unit 13, the drive unit 13 can drive the drive gear 221 to reciprocate in a rotary drive manner, specifically through the cooperation of a motor and a linkage mechanism; at the same time, the drive unit 13 can also drive in a linear reciprocating manner, specifically through the cooperation of a linear electric cylinder and a rack.

[0039] In practical use, operators can also set effective teeth on the driving gear and driven gear 25 according to the reciprocating stroke to reduce processing difficulty and cost.

[0040] It should also be noted that the first shaft 21, the second shaft 22, and the third shaft 23 are identical except for the drive gear 221 and the driven gear 25.

[0041] Furthermore, this embodiment adopts a rotary drive method. Specifically, the drive unit 13 includes a drive motor 131, a turntable 132, and a connecting rod 133. The drive motor 131 is connected to one side of the housing 1. The turntable 132 is connected to the power output end of the drive motor 131. The turntable 132 is provided with an eccentrically arranged first connecting post 1321, and the drive gear 221 is provided with a second connecting post 2211. The two ends of the connecting rod 133 are rotatably connected to the first connecting post 1321 and the second connecting post 2211, respectively. Under the drive of the drive motor 131, the turntable 132 drives the drive gear 221 to reciprocate in a rotary drive manner.

[0042] Implicitly, the drive motor 131 is mounted on one side of the housing 1 via a fixed bracket. The power output end of the drive motor 131 drives the turntable 132 to rotate. The turntable 132 drives one end of the connecting rod 133 to move synchronously through the eccentrically set first connecting column 1321, so that the connecting rod 133 drives the drive gear 221 to rotate synchronously. Based on the length design of the connecting rod 133, the swing angle of the second connecting column 2211 is less than 180 degrees. That is, when the first connecting column 1321 completes one revolution, the movement trajectory of the second connecting column 2211 is an arc. In this way, the turntable 132 and the connecting rod 133 convert the rotation of the drive motor 131 into the swing of the drive gear 221, so that the shaft 2 reciprocates and rotates, thereby driving the dispersion component 24 to swing inside the housing 1.

[0043] Preferably, the dispersing components 24 are staggered along the length of the shaft 2. This staggered arrangement of the dispersing components 24 can more effectively break up agglomerated materials, promote material flow, and reduce dead zones. Furthermore, with the horizontal plane containing the axis of the shaft 2 as the boundary, the dispersing components 24 are arranged in the upper half of the shaft 2. More specifically, by arranging the dispersing components 24 in the upper half of the shaft 2, the shearing force of the dispersing components 24 is mainly distributed above the shaft 2, intervening only in the material above the shaft 2. This avoids generating redundant stirring resistance for the material already flowing naturally below the shaft 2, and also results in a shorter movement distance and more frequent shearing of the dispersing components 24.

[0044] In this embodiment, the dispersing component 24 is a blade 241. The blade 241 can be installed above the shaft 2 by welding. In actual use, the blade 241 is designed to provide stronger shearing and flow action, which can effectively break up agglomerated materials.

[0045] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
