TECHNICAL FIELD
[0001] The present application relates to the technical field of buffer silo, in particular to a silo material buffer structure and a silo. BACKGROUND
[0002] In the metallurgical industry, with the expansion of production scale and the improvement of environmental protection requirements, the material supply mode has undergone major changes. From the simple yard of each factory area, the respective feeding system gradually changes to the unified comprehensive mechanized raw material yard. The metallurgical industry involves various processes, including sintering plant, pellet plant, coking plant, iron plant, lime kiln, steel plant, etc. Each plant consumes many types of materials, each with different types, such as sintering plant needs multiple types of iron ore powder, fuel (coal, coke powder), etc.; pellet plant needs multiple types of iron concentrate powder; coking plant needs multiple types of coal; iron plant needs coke, miscellaneous ore, etc.; lime kiln needs limestone; steel plant needs various alloy additives, etc. Each plant has its own feeding system, and these raw fuels are supplied by the respective feeding system. The storage of materials is stored in the respective simple yard or stockyard, mostly by truck transportation and semi-underground receiving bin receiving mode. Large state-owned enterprises have the capacity to build comprehensive mechanized raw material yards, and most private enterprises have dispersed simple yards, with manual and loader operation, poor environment and high labor intensity.
[0003] In recent years, private enterprises have greatly improved their strength, and with the transformation and replacement of production capacity, private enterprises have further expanded their production scale. Building a comprehensive mechanized raw material yard can reduce vehicle transportation in the plant area, reduce labor intensity, and reduce costs.
[0004] However, this change has brought new problems, that is, the material transportation capacity of the comprehensive mechanized raw material yard does not match the receiving capacity of each user point. Each user's feeding system has its own set or several sets of semi-underground receiving bins to accept different types of materials, and each set of semi-underground receiving bins is generally composed of several receiving bins, which can only accept a few trucks of materials and have no storage function. The present material is supplied by the comprehensive raw material yard, and the incoming transportation volume is large.
[0005] At the same time, the buffer bin is a key component in the skip quantitative loading system, and the different loads of the material cause the buffer bin to be damaged. In industrial production, mine production, transportation and other production line systems, there are different links of logistics systems, and sometimes it is necessary to add a buffer bin in the logistics system. The upper part of the existing silo is mostly cylindrical or prismatic, and the lower part is contracted into a conical hopper with a discharge port, and the material in the silo is discharged from the bottom discharge port by gravity, but the discharge port is often blocked during discharge, which is not convenient for discharging the material.

[0029] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the application provides a stock bin material buffering structure.
[0030] The buffer bin 2 is provided with a anti-blocking mechanism. It should be noted that the anti-blocking mechanism is used for anti-blocking treatment of the discharging hole 3 on the buffer bin 2, so as to avoid the blocking phenomenon during material discharging.

[0033] Through the anti-blocking mechanism, the hydraulic cylinder 4 is started, so that the circular table 11 is unblocked from the discharging hole 3, and the material in the buffer bin 2 can fall through the inclined surface of the circular table 11. During the material discharging process, the hydraulic cylinder 4 and the driving motor 12 are started. When the hydraulic cylinder 4 is started, the circular table 11 can continue to move downward by a distance and then move upward by a distance. In this way, the agitating piece 13 can move vertically and reciprocally, the driving motor 12 can drive the agitating piece 13 to rotate, and thus the material at the discharging hole 3 can be discharged.

The power motor 6 is fixedly installed on the top end of the disc 5, the output end of the power motor 6 is fixedly connected with the power piece 7, and the rubber knocking ball 8 is fixedly installed on the power piece 7.
[0035] Through the anti-blocking mechanism, the disc 5 drives the power motor 6 to move vertically and reciprocally during the vertical and reciprocating movement of the circular table 11. The power motor 6 is started, so that the power piece 7 drives the rubber knocking ball 8 to rotate, the rubber knocking ball 8 knocks the buffer bin 2, the buffer bin 2 vibrates, and thus the material in the buffer bin 2 is further discharged, and the blocking phenomenon during the discharging process can be effectively prevented.
[0036] Specifically, the buffer bin 2 is provided with a feeding pipe 15 at the top, and buffer guide plates one 16 and two 17 are fixedly arranged in the buffer bin 2. It should be noted that the material can be buffered and guided, so as to avoid the direct impact of the material on the lower section of the buffer bin 2, that is, the conical part of the buffer bin 2, and the lower section of the buffer bin 2 is well protected.

[0039] Specific, the buffer bin 2 and support frame 1 between fixedly provided with reinforcing member 14, reinforcing member 14 fixedly sleeved in the lower section of the buffer bin 2, reinforcing member 14 top is provided with a vertical hole, the vertical plate 9 is slidingly installed in the vertical hole, it should be noted that, can improve the stability of the lower section of the buffer bin 2.
[0040] It should be noted that, the utility model discloses a bin is installed above the receiving chute, each receiving chute is additionally provided with a bin, which can store and buffer incoming materials of the mechanized comprehensive raw material yard, and the whole implementation process does not damage the original facilities and does not affect the current material supply production.
[0041] Working principle:
[0042] S1: start the hydraulic cylinder 4, the hydraulic cylinder 4 drives the disc 5 to move down, the disc 5 drives the vertical plate 9 to move down, the vertical plate 9 drives the circular table 11 to move down through the connecting piece 10, so that the circular table 11 removes the blocking of the discharge hole 3, moves the circular table 11 a distance, at this time, the material in the buffer bin 2 can fall through the inclined surface of the circular table 11, facilitating the material to discharge;
[0043] S2: in the process of material discharging, start the hydraulic cylinder 4, drive motor 12 and power motor 6, the hydraulic cylinder 4 can make the circular table 11 continue to move down a distance and then rise a distance when starting, so as to make the stirring member 13 move reciprocatingly in the vertical direction, the drive motor 12 can drive the stirring member 13 to rotate, so as to assist the material at the discharge hole 3 to discharge;
[0044] S3: the circular table 11 moves back and forth in the vertical direction slowly, which can drive the power motor 6 to move back and forth in the vertical direction slowly, the power motor 6 can drive the power member 7 to rotate when starting, so that the rubber knocking ball 8 knocks the buffer bin 2, so that the buffer bin 2 vibrates, which further assists the material in the buffer bin 2 to discharge, and can effectively prevent the phenomenon of blockage during discharging.
[0045] The material buffer structure of the bin has been successfully applied in actual projects. In the intelligent fully enclosed comprehensive material yard project of a certain large steel enterprise, the 'bin + groove' material buffer process has shown excellent performance. When multiple semi-underground receiving grooves are modified, due to the limitation of the site, the newly built structure needs to be close to the existing receiving groove, which brings challenges to the foundation design. The new storage bin structure form we used is a steel structure frame, and the foundation is a large-diameter cast-in-place pile. A single pile is arranged under the column. Through special design, a single column and single pile form is finally adopted. A large-diameter artificial hole digging and bottom expanding cast-in-place pile that meets the design requirements is used. The pile top and steel column are connected by an external wrapped column foot, successfully solving the foundation design difficulty. The newly built large steel bin is [specific length] meters long, [specific width] meters wide, and [specific height] meters high. The lower conical section is sealed with the surrounding environment. The original feeding mode can be retained by using the space at the conical section, ensuring the smoothness and environmental friendliness of the feeding. During the entire project implementation process, no damage was caused to the original facilities, and the feeding production at that time was not affected, fully verifying the feasibility and effectiveness of the technology in actual complex environments.
[0046] Compared with the traditional solution of adding a receiving groove behind the semi-underground receiving groove and extending the receiving belt conveyor at the lower part of the receiving groove, the 'bin + groove' material buffer process has obvious advantages. The traditional method faces many problems in actual application. First, it is severely limited by the site, often lacking enough space to implement. Second, the number of receiving grooves is limited, which directly leads to a limited storage capacity for receiving materials, which cannot meet the buffering requirements of a large amount of materials. Moreover, this method also affects normal production and requires the addition of a vibrating feeding device, increasing costs and the complexity of equipment maintenance. On the contrary, the 'bin + groove' material buffer process can effectively save space and has unlimited storage capacity under existing site conditions, which can maximize the material buffering requirements. During construction, it does not interfere with existing production and does not require additional vibrating feeding equipment, greatly reducing costs and the complexity of production and operation, reflecting the innovation and high cost performance of the technology.
[0047] The above provides a detailed introduction to the material buffer structure of the bin and the bin. The principles and implementation methods of the application are described in the specific examples. The above examples are only used to help understand the method and its core idea. It should be noted that for ordinary skilled persons in the technical field, without departing from the principles of the application, the application can be improved and modified, and these improvements and modifications also fall within the protection scope of the claims of the application.
