Description

Technical Field

[0001] The utility model relates to the technical field of bulk material conveying, in particular to a bulk material structure of a feeding station. Background Art

[0002] In the existing feeding station system, the conveying and converging of bulk materials is a key link. The usual method is to introduce materials from above into a container below through a pipeline. However, the design of this pipeline has the following several significant problems in practical applications:

[0003] 1. Material blockage and accumulation: The structural design of a single pipeline often fails to meet the smooth falling of materials with different particle sizes and shapes, and it is easy to cause blockage in the pipeline. Especially when large pieces of materials gather together, the operating efficiency of the system is greatly reduced, and even the equipment may stop running.

[0004] 2. Uneven material distribution: In the traditional feeding process, due to the lack of an effective distribution and guiding mechanism, materials often form a concentrated accumulation in the pipeline and cannot be evenly distributed into the container below. This uneven distribution not only affects the processing effect of materials but also may have an impact on subsequent production links.

[0005] 3. Poor system stability: The traditional structure of the feeding station usually adopts a simple support and fixation method and cannot maintain stability during long-term operation. The impact and friction of materials will gradually weaken the stability of the structure, resulting in frequent maintenance and repair of the equipment, increasing production costs and time.

[0006] To solve the above problems, the following several methods are usually adopted in the industry:

[0007] 1. Multi-section conveying pipeline: On the basis of a single pipeline, the pipeline is divided into multiple sections, and materials are guided and distributed through different angles and positions. However, this method has limited effect in solving the problems of material blockage and accumulation, and due to the complex structure, it increases the manufacturing and maintenance costs of the equipment.

[0008] 2. Vibration conveying device: By setting a vibration device in the conveying pipeline, the vibration force is used to disperse and guide the materials to reduce the problems of material accumulation and blockage. However, the introduction of the vibration device places higher requirements on the stability of the system, and the vibration may cause damage to some fragile materials, affecting the integrity of the materials.

[0009] 3. Pneumatic conveying technology: The pneumatic conveying technology is used to convey and distribute materials, and by controlling the speed and direction of the air flow, the problems of material blockage and accumulation are avoided. However, the pneumatic conveying technology is relatively high in energy consumption and cost, and has certain requirements for the shape and density of materials, so its application range is limited.

[0010] Therefore, how to improve the aggregation efficiency of materials and prevent blockage has become the technical problem to be solved by the present utility model. Summary of the Utility Model

[0011] The technical problem solved by the present utility model is to provide a bulk material structure for a loading station to solve the problems of material blockage, uneven distribution, and poor system stability in the above-mentioned background art in view of the defects existing in the above-mentioned prior art.

[0012] To solve the above technical problems, the technical solutions adopted by the present utility model are as follows:

[0013] A bulk material structure for a loading station includes a telescopic pipe, which has a pipe cavity. The bulk material structure of the loading station further includes a main area aggregation structure; in the pipe cavity, at least three main area aggregation structures are sequentially arranged in the direction from top to bottom;

[0014] Each main area aggregation structure includes a trapezoidal guide pipe and a connecting bracket;

[0015] The trapezoidal guide pipe is fixed on the inner side wall of the telescopic pipe through the connecting bracket;

[0016] The axial section of the trapezoidal guide pipe is trapezoidal, and the upper end of the trapezoidal guide pipe is the large bottom end of the trapezoid, and the lower end is the small bottom end of the trapezoid;

[0017] At least three main area aggregation structures include one adjacent main area aggregation structure located above and one adjacent main area aggregation structure located below;

[0018] The small bottom end of the trapezoid of the trapezoidal guide pipe of the adjacent main area aggregation structure located above faces the large bottom end of the trapezoid of the trapezoidal guide pipe of the adjacent main area aggregation structure located below.

[0019] As a further solution of the present utility model, the trapezoidal center line of the trapezoidal guide pipe of the adjacent main area aggregation structure located above and the trapezoidal center line of the trapezoidal guide pipe of the adjacent main area aggregation structure located below are on the same straight line.

[0020] As a further solution of the present utility model, the number of the main area aggregation structures is 5.

[0021] As a further solution of the present utility model, the connecting bracket includes a connecting ring and connecting plate pieces. The number of the connecting plate pieces is at least 3. The at least 3 connecting plate pieces are evenly distributed on the outer circumference of the trapezoidal guide pipe. And the connecting plate pieces are located between the trapezoidal guide pipe and the connecting ring. One end of the connecting plate piece is fixedly connected to the annular inner side surface of the connecting ring, the other end of the connecting plate piece is fixedly connected to the trapezoidal guide pipe, and the annular outer side surface of the connecting ring is fixedly connected to the inner side wall of the telescopic pipe.

[0022] As a further solution of the utility model, the number of connecting plate pieces is 4.

[0023] As a further solution of the utility model, the connecting plate piece includes a long side surface, and the long side surface of the connecting plate piece is vertically oriented downward.

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0025] 1. Multi-stage converging material body function: By arranging at least three main area converging structures in the lumen of the telescopic tube, each main area converging structure is composed of a trapezoidal material guiding tube and a connecting bracket, the multi-stage convergence of bulk materials can be realized. This design enables the material to be gradually introduced into the next-stage trapezoidal material guiding tube, significantly improving the convergence efficiency and uniformity of the material. The axial section of the trapezoidal material guiding tube is trapezoidal, and the upper and lower ends are respectively the large bottom end and the small bottom end of the trapezoid, ensuring that the material can smoothly converge step by step from top to bottom under the action of gravity, avoiding the accumulation and blockage of the material.

[0026] 2. Multi-stage cutting material body effect: The trapezoidal material guiding tubes of adjacent main area converging structures are arranged with the upper part smaller and the lower part larger, so that the material enters the large bottom end of the next-stage trapezoidal material guiding tube through the small bottom end of the trapezoid during the falling process. This structural design can not only effectively converge the material, but also cut the material during the falling process of the material, avoiding the accumulation of large pieces of material and contributing to the further uniform distribution of the material. The connecting bracket adopts a combined design of a connecting ring and a connecting plate piece. The connecting plate pieces are evenly distributed on the outer circumference of the trapezoidal material guiding tube, and the number is at least three (preferably four). This evenly distributed structure ensures the stability and durability of the trapezoidal material guiding tube, and also plays the role of multi-stage cutting of the material body.

[0027] 3. Efficient and stable structural design: The center line of the trapezoidal material guiding tube of the main area converging structure is on the same straight line as the center line of the adjacent trapezoidal material guiding tube, ensuring the stability of the material path during the falling process and reducing the lateral offset of the material. The overall structure is fixed by multiple connecting plate pieces and connecting rings to form a stable and efficient multi-stage converging and cutting material body, ensuring the reliability and durability of the equipment during long-term operation.

[0041] Embodiment 1:

[0042] In this embodiment, a bulk material structure for a feeding station is provided to effectively solve the problems of material blockage, uneven distribution and poor system stability in the prior art. The bulk material structure includes a telescopic pipe 1 having a pipe cavity 2, and five main area converging structures 3 are sequentially arranged in the pipe cavity 2 from top to bottom.

[0043] Each main area converging structure 3 includes a trapezoidal material guiding pipe 4 and a connecting bracket 5. The trapezoidal material guiding pipe 4 is fixed to the inner side wall of the telescopic pipe 1 through the connecting bracket 5. The axial cross-section of the material guiding pipe is trapezoidal, with the upper end being the large bottom end of the trapezoid and the lower end being the small bottom end of the trapezoid. The trapezoidal material guiding pipes 4 of the adjacent main area converging structures 3 are arranged vertically, so that the small bottom end of the upper trapezoidal material guiding pipe 4 faces the large bottom end of the lower trapezoidal material guiding pipe 4. Through this arrangement, the materials are gradually converged during the falling process, effectively preventing the blockage and accumulation of the materials.

At the same time, through the arrangement of the small bottom end and the large bottom end of adjacent trapezoidal guiding pipes 4, the material is effectively cut during the falling process, further improving the uniform distribution effect of the material.

[0046] Adopting the bulk material structure of this embodiment can significantly improve the material convergence efficiency and uniformity of the loading station system, reduce the occurrence of material blockage, and enhance the stability and operation efficiency of the system.

[0047] Embodiment 2:

[0048] In this embodiment, a bulk material structure for a loading station is provided to achieve a multi-level converging material body, a multi-level cutting material body, and an efficient and stable structural design.

[0049] This bulk material structure includes a telescopic pipe 1 with a pipe cavity 2, and five main area converging structures 3 are sequentially arranged in the pipe cavity 2 from top to bottom. Each main area converging structure 3 is composed of a trapezoidal guiding pipe 4 and a connecting bracket 5. The trapezoidal guiding pipe 4 is fixed on the inner side wall of the telescopic pipe 1 through the connecting bracket 5, and the axial section of the guiding pipe is trapezoidal, with the upper end being the large bottom end of the trapezoid and the lower end being the small bottom end of the trapezoid.

[0050] Function of multi-level converging material body: After the material enters the telescopic pipe 1 from above, it first enters the large bottom end of the uppermost trapezoidal guiding pipe 4. Under the action of gravity, the material is gradually guided into the small bottom end of the next-level trapezoidal guiding pipe 4, achieving step-by-step convergence. This design significantly improves the material convergence efficiency and uniformity, avoiding the accumulation and blockage of the material.

[0051] Effect of multi-level cutting material body: The trapezoidal guiding pipes 4 of adjacent main area converging structures 3 are arranged in a pattern where the upper part is small and the lower part is large. The material enters the large bottom end of the next-level trapezoidal guiding pipe 4 through the small bottom end of the upper-level trapezoidal guiding pipe 4 during the falling process. This design not only effectively converges the material but also cuts the material during the falling process, preventing the accumulation of large pieces of material and promoting the uniform distribution of the material. The connecting bracket 5 is composed of a connecting ring 6 and four uniformly distributed connecting plate pieces 7. The connecting plate pieces 7 are uniformly distributed on the outer circumference of the trapezoidal guiding pipe 4, with one end fixedly connected to the annular inner side surface of the connecting ring 6 and the other end fixedly connected to the trapezoidal guiding pipe 4, ensuring the stability and durability of the trapezoidal guiding pipe 4 and at the same time playing the role of cutting the material body.

[0052] Efficient and stable structural design: The center line of the trapezoidal material guiding pipe 4 of the main area converging structure 3 is on the same straight line as the center lines of adjacent trapezoidal material guiding pipes 4, ensuring the path stability of the material during the falling process and reducing the lateral offset of the material. The overall structure is fixed by multiple connecting plates 7 and connecting rings 6, forming a stable and efficient multi-stage converging and cutting material system, ensuring the reliability and durability of the equipment during long-term operation.

[0053] In practical applications, this bulk material structure is installed in the conveying system of the feeding station. After the material enters the telescopic pipe 1 from above, due to the step-by-step convergence and cutting effect of the trapezoidal material guiding pipe 4, the material can be smoothly guided from top to bottom into the next-level trapezoidal material guiding pipe 4, avoiding blockage and accumulation of the material in the pipe cavity 2. At the same time, through the arrangement of the small bottom ends and large bottom ends of adjacent trapezoidal material guiding pipes 4, the material is effectively cut during the falling process, further improving the uniform distribution effect of the material.

[0054] Adopting the bulk material structure of this embodiment can significantly improve the material convergence efficiency and uniformity of the feeding station system, reduce the occurrence of material blockage, and enhance the stability and operation efficiency of the system. This design solves the core problems in the prior art and has important practical value and promotion prospects.
