Description

Technical Field

[0001] This utility model relates to a circular silo, and more particularly to an automatic feeding and discharging circular silo that avoids material stratification, belonging to the field of storage equipment technology. Background Technology

[0002] Grains, soybean meal, and other materials are typically stored long-term in circular silos, with a discharge machine at the bottom of the silo. For example, Chinese invention patent CN105645127B discloses a discharge mechanism for a circular silo, including a main reducer, a coupling, a discharge auger, and a tail mechanism. The main reducer is located at the center of the silo, and its output shaft is connected to the auger shaft via the coupling. The outer end of the auger shaft is connected to the tail mechanism. The portion of the auger shaft other than its ends is composed of multiple hollow long shafts nested and welded together, with more nesting layers closer to the center. Spiral blades are wound axially around the outer periphery of the auger shaft. The pitch of the spiral blades is uniform on each stepped section of the shaft, and the volume within the spiral blade pitch gradually increases from the tail end to the center end. Each spiral blade has a shearing blade mounted on its outer edge. The output shaft of the main reducer is supported on the wall plates on both sides of the main reducer by double-row radial spherical roller bearings, and a double-direction thrust ball bearing is installed at the end of the main reducer output shaft away from the discharge auger.

[0003] This circular silo only has a discharge mechanism at the bottom, and the material is fed in through a chute from the center of the top of the silo. This has the following drawbacks: 1. Material falls freely from the center of the silo, forming a cone at the bottom. Fine powder, with poor flowability, accumulates in the central area, which is relatively dense due to the continuous impact of the falling material. Larger particles roll outwards along the cone, accumulating naturally around the perimeter of the silo with a lower density, thus creating natural gradation and stratification. This results in higher bulk density and protein content in the material near the center and bottom, and lower bulk density and protein content in the material near the perimeter and top. This makes it difficult to accurately control protein levels during later production. After the material leaves the silo, downstream production equipment experiences unstable production indicators, making equipment adjustments difficult and product quality hard to control, thus affecting the overall output and quality of the production line.

[0004] 2. The materials of different sizes were not mixed together and piled up evenly. The small powder particles were concentrated in the central area and were relatively dense. They were more prone to caking during storage, which made it difficult to unload the materials later. The unloading machine was difficult to start and it was easy to cause the silo to become stuffy. In actual work, the silo had to be turned over in a short time, which increased energy consumption and workload.

[0005] 3. During the feeding process, dust is generated, which not only pollutes the environment and affects the physical and mental health of people in the surrounding area, but also increases the difficulty of dust explosion prevention. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] In view of the problems existing in the above and / or prior art, this utility model is proposed.

[0008] The purpose of this invention is to provide an automatic feeding and discharging circular hopper that avoids material stratification. This solves the problem of stratification caused by inconsistent particle size during the descent of materials, and avoids the impact of material stratification on equipment production indicators, production output, and the quality of output products.

[0009] To solve the above technical problems, this utility model provides an automatic feeding and discharging circular hopper that avoids material stratification. The bottom of the circular hopper is equipped with a discharge mechanism, and the upper port of the circular hopper is equipped with: A support truss is fixed to the upper inner wall of the circular silo, and a rotatable rotary support mechanism is provided at the center. A fabric ring track is located below the supporting truss and is fixed to the upper inner circumferential wall of the circular hopper; A radial platform extends along the diameter of the hopper and is supported at both ends by trolleys on the fabric ring track.

A radial conveying mechanism is located in the radial platform and is capable of translating along the radial platform; The central chute extends along the axis of the circular hopper, and its lower end passes through the rotary support mechanism and is located above the radial conveying mechanism.

[0010] As an improvement of this utility model, the support truss includes multiple radial support beams extending along the diameter of the silo. The radial support beams are arranged symmetrically at the center and connected at the center as a whole. The outer ends of each radial support beam are respectively fixed to the upper inner wall of the circular silo.

[0011] As a further improvement of this utility model, the radial conveying mechanism is a telescopic scraper conveyor or a telescopic belt conveyor.

[0013] As a further improvement of this utility model, the bottom two sides of the radial conveying mechanism are respectively provided with linear tracks extending along their length direction, and multiple support pulleys are provided below the linear tracks, with the lower end of the bracket of each support pulley fixed to the radial platform.

[0014] As a further improvement of this utility model, the bottom sides of the radial conveying mechanism are symmetrically provided with limiting angle steels extending in the length direction, and the vertical sides of the two limiting angle steels are respectively located on one side of the corresponding supporting pulley.

[0016] Compared with the prior art, the present invention has achieved the following beneficial effects: 1. The discharge port of the radial conveying mechanism can extend and retract along the radial platform to realize material distribution on different radii of the silo; it can also rotate 360° along the material distribution annular track with the radial platform to realize material distribution on different phases of the silo. In this way, active and uniform material distribution is achieved on the entire area of ​​the silo, solving the problem of material stratification, improving the quality of material storage, reducing the number of times the silo is turned over, and thus reducing energy consumption. 2.

[0020] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] like Figures 1 to 9As shown, the present invention relates to an automatic feeding and discharging circular silo that avoids material stratification. The circular silo 1 has a discharge mechanism 11 at its bottom and a material distribution mechanism at its upper end. The material distribution mechanism includes a support truss 2, a material distribution annular track 4, a radial platform 5, a central chute 6, a radial conveying mechanism, and a telescopic dust cover 10. The support truss 2 is fixed to the upper inner wall of the circular silo 1 and includes multiple radial support beams extending along the diameter of the silo. The radial support beams are arranged symmetrically at the center and are connected at the center. The outer ends of each radial support beam are fixed to the upper inner wall of the circular silo 1. A rotatable rotary support mechanism 3 is provided at the central connection. The rotary support mechanism 3 is coaxial with the circular silo 1. The central chute 6 extends along the axis of the circular silo and its lower end passes through the rotary support mechanism 3.

[0023] The fabric ring track 4 is located below the support truss 2 and fixed to the upper inner circumferential wall of the circular hopper, serving as the rotation track for the radial platform 5. The radial platform 5 extends along the diameter of the hopper, with its bottom ends supported on the fabric ring track 4 by trolleys 5a. Its top center is connected to the rotation support mechanism 3. During fabric placement, the trolleys 5a at both ends jointly drive the radial platform 5 to rotate 360° along the rotation track, enabling full-phase fabric placement.

[0024] The radial platform 5 is equipped with a radial conveying mechanism that can translate along its length. The radial conveying mechanism is a telescopic scraper conveyor 7 or a telescopic belt conveyor. The following uses the telescopic scraper conveyor 7 as an example.

[0025] The lower end of the central chute 6 is aligned with the telescopic scraper conveyor 7. Two racks 7a extending along their length are respectively provided on both sides of the bottom of the telescopic scraper conveyor 7. The two racks 7a mesh with telescopic drive gears 8a, which are respectively fixed to the output shafts of the telescopic drive reduction gearboxes 8. The two telescopic drive reduction gearboxes 8 are respectively fixed to the radial platform 5. Two linear tracks 7b extending along their length are respectively provided on both sides of the bottom of the telescopic scraper conveyor 7. Multiple support pulleys 9 are provided below the linear tracks 7b, and the lower ends of the supports of each support pulley 9 are respectively fixed to the radial platform 5. Thus, the telescopic scraper conveyor 7 is supported by the support pulleys 9 on the radial platform 5. The support pulleys 9 are equipped with self-lubricating bearings to ensure rolling friction during the telescopic scraper conveyor 7's extension and retraction, reducing resistance.

[0026] After the telescopic drive reduction gearbox 8 is started, it drives the rack 7a through the telescopic drive gear 8a, thereby causing the telescopic scraper conveyor 7 to translate along the radial platform 5. Symmetrical limiting angle steels 7c extending along their length are provided on both sides of the bottom of the telescopic scraper conveyor 7. The vertical sides of the two limiting angle steels 7c are located on one side of the corresponding support pulley 9. Typically, the limiting angle steels 7c are located inside the support pulley 9, with a certain gap between them. This ensures both support and rolling, while also limiting the telescopic scraper conveyor 7 during its extension and retraction process, preventing it from tilting during translation.

[0027] In the actual material distribution process, the discharge end of the telescopic scraper conveyor 7 can start distributing material from the area near the center and gradually move towards the cylinder wall to achieve uniform material distribution in the radial direction. After distributing material along a certain radius line, the radial platform 5 rotates at a certain angle and continues distributing material along the next radius line. In this way, uniform material distribution can be achieved along the entire area of ​​the circular hopper, avoiding the grading and layering problems caused by distributing material from a single central cone.

[0028] The discharge port of the telescopic scraper conveyor 7 is equipped with a dust collection hopper, and a telescopic dust cover 10 is provided below the dust collection hopper. When the material is being distributed, the lower end of the telescopic dust cover 10 extends downward until it falls on or near the material layer to reduce dust escape. The collected dust is extracted and removed by the exhaust port on the dust collection hopper.

[0029] The above description is merely a preferred embodiment of the present utility model, showing and describing the basic principles, main features, and advantages of the present utility model. It is not intended to limit the scope of patent protection of the present utility model. Those skilled in the art should understand that the present utility model is not limited to the above embodiments.

Various changes and improvements to the present utility model are also possible. All technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by the present utility model.
