Description

Technical Field

[0001] The utility model relates to the technical field of equipment for feeding and leveling granular and dusty materials, in particular to a gravity leveling device. Background Art

[0002] In polyester production and many other similar processes, the formation of a stacking angle during pellet feeding is a common phenomenon. This stacking angle causes the pellets to accumulate into a distinct conical structure. This conical structure significantly impacts the efficient use of silo capacity, occupying space that could otherwise be used for material storage, significantly reducing the silo's actual storage capacity.

[0003] Furthermore, the stacking angle seriously interferes with the accuracy of material level detection. Due to the tapered structure, the data obtained by the level detection equipment cannot truly and accurately reflect the actual amount of material in the warehouse. This greatly complicates material management and scheduling during the production process, easily leading to production planning errors and waste of resources.

[0004] Currently, several key solutions exist to address this thorny issue. First, increasing the silo's volume to allow for sufficient space for the accumulation angle. While this approach alleviates the limited capacity issue to some extent, it also increases equipment cost and floor space. Second, installing a leveling device inside the silo can help level and smooth the accumulated material, reducing the impact of the accumulation angle and thereby improving the silo's effective volume and level detection accuracy. For example, some rotary leveling devices can gradually level the accumulated material through continuous rotation. Third, using electric or pneumatic distributors. These devices distribute and direct the incoming pellets based on pre-set programs or real-time detection data, minimizing the likelihood of accumulation angles and ensuring a more even distribution of material within the silo, thereby improving silo efficiency and level detection accuracy. For example, pneumatic distributors can evenly distribute material throughout the silo using compressed air.

[0005] Increasing the silo volume to accommodate the stacking angle not only significantly increases investment costs but also occupies additional space, posing a significant challenge in production environments with limited space. Other power solutions, such as internal leveling devices or electric or pneumatic feeders, while addressing the problem to a certain extent, increase energy consumption. Furthermore, these power systems inherently have a certain probability of failure, resulting in high maintenance and repair costs. This not only increases production costs but can also lead to production interruptions due to equipment failure, impacting overall production efficiency and product quality.

[0006] Therefore, there is an urgent need for a physical structure type material distribution mechanism to solve the problem of low volume utilization rate and uneven material distribution due to the existence of the stacking angle during the material unloading process. Utility Model Content

[0007] The purpose of the present utility model is to provide a gravity material balancing device in order to solve all or part of the technical problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A gravity material distribution device comprises a cylinder, a flat cover, a feed pipe, a spring, and a multi-layered material distribution cone;

[0010] The flat cover is fixed to the top of the silo, with the feed pipe mounted on top. A multi-layered distribution cone is located within the silo and secured to the bottom of the flat cover by a spring. The multi-layered distribution cone is positioned below the feed pipe. One end of the spring is fixed to the bottom of the flat cover, and the other end is connected to the multi-layered distribution cone. The silo provides a space for material storage, while the flat cover seals the top to prevent leakage and the ingress of foreign matter. Together, they form the main structure of the silo and ensure essential material storage conditions. The feed pipe introduces material into the silo, defining its entry point and path. The spring provides elastic support and cushioning for the multi-layered distribution cone, allowing it to move and vibrate under the impact of material, aiding in the dispersion and uniform distribution of the material. The multi-layered distribution cone, with its multiple layers of cones of varying sizes and angles, disperses and guides the falling material multiple times, gradually changing its flow direction and distribution. This reduces the formation of accumulation angles, improves silo volume utilization, and ensures uniform material distribution.

[0011] Furthermore, there are no less than three groups of springs evenly arranged at the bottom of the flat cover. The evenly distributed multiple groups of springs can more stably support the multi-layer distribution cone, ensure that the force is evenly applied, thereby making the movement and vibration of the distribution cone more stable and effective, and enhancing the dispersion effect on the material.

[0012] In an embodiment that optimizes the aforementioned solution, a limiting rod is further included. The limiting rod passes through the spring, with one end of the limiting rod fixed to the lower portion of the flat cover and the other end of the limiting rod being free. The limiting rod passes through the spring to limit excessive stretching of the spring, ensuring that the spring operates within a safe range and preventing damage due to excessive stretching. It also helps maintain the positional stability of the multi-layered distributing cone.

[0013] Furthermore, the length of the limiting rod is less than the maximum stretching length of the spring.

[0014] In an embodiment that optimizes the aforementioned solution, the multi-layered dividing cone includes a connecting plate, dividing cone 1, dividing cone 2, and dividing cone 3. Dividing cone 2 is nested within dividing cone 1, and dividing cone 3 is nested within dividing cone 2. The connecting plate is disposed within dividing cone 1, fixedly connecting dividing cones 1, 2, and 3. The outer surface of dividing cone 1 is connected to a spring. The connecting plate in the multi-layered dividing cone securely connects dividing cones 1, 2, and 3 together, ensuring that the multi-layered dividing cones function as a synergistic whole during operation, improving the effectiveness and stability of dividing materials.

[0015] Furthermore, there are no less than three groups of connecting plates, which are evenly arranged inside the first distribution cone.

[0016] Furthermore, the feed pipe has a diameter of φ1, the first distribution cone has a diameter of φ2, the second distribution cone has a diameter of φ3, and the third distribution cone has a diameter of φ4, where φ1 > φ2 > φ3 > φ4. The feed pipe diameter is larger than the distribution cone diameter, facilitating smooth material flow onto the distribution cones. The nested distribution cones of varying diameters create a gradually shrinking space, facilitating more precise material dispersion and guidance.

[0017] Furthermore, the apex angle of the first dividing cone is 120°, the apex angle of the second dividing cone is 90°, and the apex angle of the third dividing cone is 60°. Different apex angles can produce different diversion effects during the falling process of the material, further optimizing the dispersion and distribution of the material.

[0018] In an embodiment that optimizes the aforementioned solution, guide troughs are further provided. The guide troughs are arranged in groups and evenly distributed on the outer surfaces of the first, second, and third dividing cones along the downward direction of the material. These guide troughs can guide the flow of the material, enhance the dispersion of the material, and distribute it more evenly within the silo.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model discloses a gravity material leveling device, which, compared with the existing technology, can achieve uniform material distribution without applying additional power, thus reducing energy consumption and cost; the number of layers of the material distribution cone can be flexibly adjusted according to the size and distribution requirements of the silo, effectively controlling the material distribution, and enhancing the applicability of the device; the angles of the material distribution cones at each layer are inconsistent, and the sizes of the central openings at each layer are different and regularly distributed, so that the dispersion and guidance of the material when falling are more precise, thereby improving the volume utilization rate of the silo and the uniformity of material distribution; the material distribution cone is connected to the cylinder by a spring and a limit rod, which can not only shake slightly to help the material distribution, but also prevent instability, thereby ensuring the stability and safety of the device; the material guide groove on the surface of the material distribution cone makes the material distribution more even, prevents short circuits, and is conducive to material level detection and material management and scheduling; compared with the solution of increasing the volume of the silo, there is no need to significantly increase investment costs and occupy more space, and it is suitable for production environments with limited space; it also reduces the probability of power equipment failure and maintenance costs, reduces the risk of production interruption, and ensures overall production efficiency and product quality.

[0032] See Figures 1 to 3 , this embodiment provides a gravity material balancing device.

[0033] A gravity material distribution device comprises a cylinder 1, a flat cover 2, a feed pipe 3, a spring 4, and a multi-layered material distribution cone;

[0034] The flat cover 2 is fixed to the top of the cylinder 1, the feed pipe 3 is set on the flat cover 2, and the multi-layer distribution cone is set in the cylinder 1 and fixed to the lower part of the flat cover 2 by the spring 4. The multi-layer distribution cone is set below the feed pipe 3. One end of the spring is fixedly connected to the lower part of the flat cover, and the other end is connected to the multi-layer distribution cone.

[0035] In further optimization of the above solution, there are no less than three groups of springs 4, which are evenly arranged at the lower part of the flat cover 2.

[0036] The second optimized implementation of the above solution is: it also includes a limiting rod 5, the limiting rod 5 passes through the spring, one end of the limiting rod 5 is fixed to the lower part of the flat cover, and the other end of the limiting rod 5 is a free end.

[0037] In a further optimization of the above solution, the length of the limiting rod 5 is smaller than the maximum stretching length of the spring 4 .

[0038] The third optimized implementation method of the above scheme is: the multi-layer dividing cone includes a connecting plate 6, a dividing cone 1 7, a dividing cone 2 8, and a dividing cone 3 9. The dividing cone 2 8 is nested in the dividing cone 1 7, and the dividing cone 3 9 is nested in the dividing cone 2 8. The connecting plate 6 is arranged inside the dividing cone 1 7 to fix the dividing cone 1 7, the dividing cone 2 8, and the dividing cone 3 9. The outer surface of the dividing cone 1 7 is connected to the spring 4.

[0039] In further optimization of the above solution, there are no less than three groups of connecting plates 6, which are evenly arranged inside the dividing cone 7.

[0040] In further optimization of the above scheme, the diameter of the feed pipe 3 is φ1, the diameter of the distribution cone 1 7 is φ2, the diameter of the distribution cone 2 8 is φ3, and the diameter of the distribution cone 3 9 is φ4, φ1>φ2>φ3>φ4.

[0041] In further optimization of the above solution, the apex angle of the dividing cone 1 7 is 120°, the apex angle of the dividing cone 2 8 is 90°, and the apex angle of the dividing cone 3 9 is 60°.

[0042] The fourth optimized implementation of the above scheme is: it also includes guide trough plates 10, and the guide trough plates 10 are divided into several groups and are evenly distributed on the outer surfaces of the dividing cone 1 7, the dividing cone 2 8, and the dividing cone 3 9 along the downward direction of the material.

[0043] Working principle:

[0044] The dividing cone 1 7 is connected to the cover plate 2 through a spring 4, and the dividing cone 1 7, the dividing cone 2 8, and the dividing cone 3 9 are connected as a whole through a connecting plate 6; the apex angle of the dividing cone 1 7 is 120°, the apex angle of the dividing cone 2 8 is 90°, and the apex angle of the dividing cone 3 9 is 90°; there are circular holes of different diameters for material discharge on the top of the dividing cone, and they are all smaller than the inner diameter of the feed pipe 3, and the relationship is as follows: φ1>φ2>φ3>φ4; a guide groove plate 10 is provided on the upper surface of the dividing cone.

[0045] Granular or dusty materials enter the cylinder 1 through the feed pipe 3 and fall onto the top of the dividing cone 1 7. Since the center opening of the dividing cone is smaller than the inner diameter of the feed pipe, part of the material falls onto the top of the lower dividing cone 2 8 through the opening, and part of the material falls onto the upper surface of the dividing cone 1 1. The material is evenly dropped into the cylinder through the guide trough plate 10 welded to the upper surface of the dividing cone. Through the same process, the material is distributed through the openings and guide grooves of the dividing cone 2 8 and the dividing cone 3 9 and falls into the inside of the silo. Due to the different angles of the dividing cones, the distribution circles of the material discharged through the guide grooves are different, and the positions of the dropped materials are inconsistent, thus forming a uniform distribution of the material. Since the dividing cone 1 7 is connected to the upper cover by a spring 4, it will produce a certain amount of shaking under the impact of the feed, so that the dropped materials are more evenly distributed within a certain position range. At the same time, since a limiting rod 5 is set inside the spring, it can be guaranteed that no large displacement will occur.

[0046] like Figure 2 As described above, by simulating the single-hole discharge and the material accumulation state after distribution through the discharger, it can be seen that the material is distributed more evenly after passing through the discharger.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
