Description

Technical Field

[0001] This utility model relates to a silo device, and more specifically, to a movable flexible arch-breaking silo. Background Technology

[0002] In the storage and transportation of bulk materials (such as powders, granules, and fibers), bridging (also known as arching or bridging) is a common technical challenge. When the flowability of materials decreases due to internal friction between particles, electrostatic forces, or hygroscopicity, a stable arched structure forms inside the silo, hindering the normal flow of materials. This phenomenon is common in industries such as chemical, plastics processing, feed, and grain storage, and manifests as: interrupted feeding: materials cannot be discharged from the outlet, requiring manual intervention or machine shutdown for cleaning, reducing production efficiency; uneven pressure: excessive local compression of materials leads to clumping, and may even cause damage to the silo structure; increased energy consumption: traditional methods of breaking arches rely on high-frequency mechanical vibration or high-pressure airflow, which are energy-intensive and have unstable effects.

[0003] To address the bridging effect, the industry typically uses mechanical vibration to break up the bridging. This involves vibrating or striking the hopper to break up the clumps of material inside, thus achieving the bridging process.

[0004] This utility model provides a new technical solution to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a movable soft arch-breaking hopper.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A movable flexible arch-breaking hopper includes a hopper body and an arch-breaking mechanism. The bottom of the hopper body is provided with a discharge port. The arch-breaking mechanism includes a lifting driver, a lifting seat, and rollers. The lifting driver is installed vertically inside the hopper body and has a lifting part that can move up and down. The lifting seat is fixedly installed on the lifting part. The rollers are rotatably connected to the lifting seat through a rotating shaft, and the rotating shaft is perpendicular to the up and down lifting direction. The rollers protrude from the lifting seat and move up and down with the lifting part to squeeze and break the arches of the material.

[0008] The present invention is further configured to include a deformable flexible container, the interior of which is used to store bulk materials, and the flexible container is adapted to the inner cavity space of the silo body and can be placed inside the silo body.

[0009] The present invention is further configured such that a second discharge port is provided at the bottom of the flexible container, and the second discharge port is positioned opposite to the first discharge port.

[0010] The present invention is further configured such that the lower part of the silo body forms a constricted section that gradually narrows downwards, and a discharge port is provided at the lowest end of the constricted section.

[0011] The present invention is further configured such that a second constriction portion is formed at the lower part of the flexible container to fit the first constriction portion, and a second discharge port is provided at the lowermost end of the second constriction portion.

[0012] The present invention is further configured such that the flexible container is placed inside the chamber, the roller is in contact with the outer side of the flexible container, and is partially embedded in the outer recess of the flexible container.

[0013] The present invention is further configured such that both the upper and lower sides of the lifting seat have inclined chamfers.

[0014] The present invention is further configured such that the arch-breaking mechanism is provided in two sets, which are symmetrically installed on the inner wall of the silo.

[0015] The present invention is further configured such that a drive motor is provided on the upper part of the lifting drive, and the drive motor extends from the upper opening of the compartment.

[0016] The present invention is further configured such that the cross-section of the hopper is quadrilateral, with rounded transitions at the corners.

[0017] In summary, this utility model has the following beneficial effects:

[0018] Flexible containers are used to form flexible living silos as the main storage body for bulk materials. The flexible containers can deform appropriately with the material. Through external rollers, the flexible containers are squeezed and compressed by time, which can cause local deformation to destroy the arch structure of the material, thereby achieving arch breaking. Moreover, in the process of arch breaking, the rollers and other components can be kept out of direct contact with the material, which can effectively avoid unnecessary contamination of the material.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment discloses a movable soft arch-breaking hopper, referring to... Figure 1-5 As shown, the container includes a storage chamber 1 and an arch-breaking mechanism. The storage chamber 1 has a rigid structure with a discharge port 102 at the bottom and an open top, allowing the flexible container 5 to be placed inside. The arch-breaking mechanism is installed inside the storage chamber 1, specifically near the inner wall. The mechanism uses the external reagent compression force to break up the arches in the bulk material inside the flexible container 5, facilitating its smooth descent.

[0029] Reference Figures 1-3 As shown, the cross-section of the silo body 1 is quadrilateral, with rounded transitions at the corners; the lower part of the silo body 1 forms a narrowing section 101 that gradually narrows downwards, and the bottom of the narrowing section 101 has a discharge port 102.

[0030] Two sets of arch-breaking mechanisms are symmetrically installed on the inner wall of the silo body 1. Each arch-breaking mechanism includes a lifting drive 2, a lifting base 3, and rollers 4. The lifting drive 2 is a linear actuator, vertically installed on the inner wall of the silo body 1, and has a lifting section 201 capable of vertical movement. When the lifting drive 2 is working, it drives the lifting section 201 to move up and down along a running trajectory. A drive motor 202 is located on the upper part of the lifting drive 2, extending from the upper opening of the silo body 1 during installation.

[0031] The lifting seat 3 is fixedly installed on the lifting part 201. Each lifting drive 2 has two lifting seats 3 fixedly installed on its lifting part 201. The two lifting seats 3 are installed side by side, and the roller 4 is rotatably connected between the lifting seats 3 through the rotating shaft 401. The two lifting seats 3 can respectively support the two ends of the rotating shaft 401 to maintain the structural stability of the roller 4.

[0032] The rotating shaft 401 is perpendicular to the vertical lifting direction. The roller 4 protrudes from the lifting seat 3 and moves up and down with the lifting part 201. During the vertical movement, part of the roller 4 can press against the outside of the flexible container 5 to form a rolling fit, which can maintain the smoothness of the lifting and arch-breaking action and reduce the resistance generated by the lifting action.

[0033] The flexible container 5 is a deformable flexible structure that can store bulk materials. Furthermore, the flexible container 5 is adapted to the internal space of the storage chamber 1 and can be placed inside the storage chamber 1. For example, the flexible container 5 can be made of woven fabric, giving it a flexible and deformable structure that allows for the rotation of appropriate materials depending on the stored materials.

[0034] To prevent the flexible container 5 from collapsing, annular reinforcing ribs can be installed around its outer perimeter. These ribs can be made of elastic metal or plastic rings and can be bonded to the outside of the flexible container 5 or inserted into the interlayer of the flexible container 5. The reinforcing ribs can maintain the general stability of the outline of the flexible container 5 and allow the arch-breaking mechanism to apply compressive force to the outside of the flexible container 5.

[0035] A discharge port 2 502 is provided at the bottom of the flexible container 5, and the position of the discharge port 2 502 is opposite to that of the discharge port 1 102. The lower part of the flexible container 5 forms a constriction section 2 501 that is adapted to the constriction section 1 101, and the discharge port 2 502 is provided at the bottom of the constriction section 2 501.

[0036] When the flexible container 5 is placed into the silo 1, the discharge port 2 502 is opposite to the discharge port 1 102, and the material stored in the flexible container 5 can fall out from the discharge port 2 502 and the discharge port 1 102.

[0037] Reference Figure 4 , Figure 5As shown, the distance between the rollers 4 of the two sets of arch-breaking mechanisms is less than the width of the flexible container 5. When the flexible container 5 is placed inside the silo 1, the rollers 4 of the arch-breaking mechanism can contact the outer side of the flexible container 5, and part of the rollers 4 can be embedded into the recessed area on the outer side of the flexible container 5. When the silo releases material, the rollers 4 can be moved up and down by the lifting drive 2, which can apply a lateral squeezing force to the outer side of the flexible container 5, destroy the internal "arch" support points, release the static pressure of the material, and avoid the undesirable situation of local compaction and agglomeration causing arching.

[0038] Furthermore, inclined chamfers 301 are formed on both the upper and lower sides of the lifting seat 3, and the edges of the inclined chamfers 301 form an arc transition. During the lifting process, the lifting seat 3 may also be squeezed against the outer side of the flexible container 5, and may sink into the surface of the flexible container 5. By setting the inclined chamfers 301, a guiding function can be provided to maintain the smoothness of the lifting seat 3 against the surface of the flexible container 5 during the lifting process.

[0039] When the flexible container 5 is placed into the silo 1, the lifting part 201 can be adjusted downwards, and the lifting seat 3 and roller 4 can be adjusted to the lowest position. When it is necessary to break the arch of the material, the lifting part 201 can be adjusted up and down appropriately to apply appropriate pressure to the flexible container 5, thereby achieving the effect of breaking the arch.

[0040] Furthermore, based on the above embodiments, and with reference to... Figure 6 As shown, two baffles 6 can be installed inside the chamber 1. The baffles 6 are installed on the outside of the lifting drive 2, and can form a barrier outside the lifting drive 2. A accommodating space for storing the flexible container 5 is formed between the two baffles 6, and the shape of the flexible container 5 is approximately adapted to the size of the accommodating space.

[0041] A vertically oriented guide groove 601 is provided in the middle of the baffle 6, through which the roller 4 and the lifting seat 3 can pass and extend into the accommodating space between the two baffles 6. Furthermore, the direction of the guide groove 601 is consistent with the lifting direction of the roller 4 and the lifting seat 3, which can ensure that the roller 4 can move up and down smoothly.

[0042] By blocking the baffle 6, direct contact between the outside of the lifting drive 2 and the flexible container 5 can be avoided, thus maintaining the smoothness of the process of placing the flexible container 5 into the chamber 1. Moreover, the roller 4 and the lifting seat 3 can still press against the outside of the flexible container 5, thus achieving the normal arch-breaking function.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
