Description

Technical Field

[0001] The utility model relates to the technical field of batching devices, in particular to an automatic raw material batching device. Background Art

[0002] In the production process of petroleum coke, it is necessary to adjust the proportion of raw materials, and the raw materials are strictly proportioned according to the formula and put into the furnace for processing. The traditional batching method adopts manual weighing. The weight of each material is weighed manually according to the ratio of the formula, and then the materials are uniformly put in. This method is time-consuming and labor-intensive, and the efficiency is low. At the same time, the labor intensity of workers is relatively high. In order to further speed up the batching efficiency and reduce the labor intensity of workers, technicians in the prior art have proposed a variety of automatic batching devices based on quantitative feeders. By understanding and controlling the weight of the unit material in advance, the quantitative feeder is used to put the raw materials on the conveyor belt for transportation according to the set amount, and finally enter the mixing stage and put in. In this process, a variety of different materials are needed. The silos are quantitatively discharged simultaneously or successively. The raw materials for petroleum coke production are large in volume due to the large amount of materials used. In the prior art, silos with an upper cylindrical structure and an inverted cone structure at the bottom are generally used to maximize the storage capacity of the silo. However, such silos have a large diameter and occupy a large space. When the raw materials are automatically batched on the same conveyor line or process route, the space occupied is extremely large. The more types of materials, the larger the space occupied, which will cause serious waste of space. Due to the volume, the discharge end of the silo is at a long distance from the conveyor belt. When unloading, because the output end of the quantitative feeder needs to extend to the top of the conveyor belt through a pipeline, residual materials will appear in the pipeline, affecting the accuracy of the final batching.

[0003] Therefore, designing a batching device that reduces the space occupied by the silo, improves space utilization, and shortens the discharge distance is exactly the problem that the inventor wants to solve. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an automatic raw material batching device that can reduce the space occupied by the silo, improve space utilization, and shorten the discharge distance.

The length of the upper structure is 4.5 times the width, the height is 3.5 times the width, the width of the upper structure is not less than 1m, and the cross-section of the lower structure is an inverted triangular structure.

[0007] Furthermore, the inclined end surfaces on both sides of the lower structure are in contact with two supporting beams respectively.

[0008] Furthermore, the upper end of the feed connector passes through the upper plate, and the feed connector is connected to an external feeding device through a pipeline.

[0010] Furthermore, a computer is arranged inside the control room, and the computer is respectively connected with all the quantitative feeders and belt conveyors by circuits.

[0011] Furthermore, the distance between the lower end of the quantitative feeder and the belt of the belt conveyor is not less than 30 cm.

[0012] Furthermore, the outlet end of the quantitative feeder is located above the belt centerline of the belt conveyor.

The silo 9 is provided with a partition plate 12 between adjacent silos 9, and the two ends of the partition plate 12 are respectively connected to the two first connecting beams 6. Reinforcing plates 8 are provided at positions of the silo 9 opposite to the first connecting beam 6 and the second connecting beam 5. The first connecting beam 6 and the second connecting beam 5 are connected to the silo 9 by connecting bolts 7 and reinforcing plates 8. The silos 9 are separated for installation by the cooperation of the end plates 15 and the partition plates 12. The reinforcing plates 8 can strengthen the parts of the silo 9 connected to the connecting bolts 7 to prevent the connection from being easily damaged or broken due to its own weight and the weight of the material.

[0020] The silo 9 includes an upper structure and a lower structure. The upper structure is a rectangular structure. The length of the upper structure is 4.5 times the width, and the height is 3.5 times the width. The width of the upper structure is not less than 1m. The cross-section of the lower structure is an inverted triangular structure. The silo 9 is flat in shape, which helps to set multiple silos 9 in parallel to save space.

[0021] In order to facilitate the installation of the silo 9, a support beam 4 is provided below the second connecting beam 5 and on the inner wall of the main frame 3. The end face of the supporting beam facing the silo 9 is an inclined surface, and the inclination angle is the same as the surface angle of the silo 9. When the silo 9 is installed from top to bottom along the end plate 15 or the partition plate 12, the lower part of the silo 9 is supported by the support beam 4, and the inclined end faces on both sides of the lower structure of the silo 9 are respectively in contact with the two support beams 4, which is convenient for installing the connecting bolts 7 at both ends, saving time and effort.

[0022] A feed joint 10 is provided at the top of the silo 9, the upper end of the feed joint 10 passes through the upper plate 11, and the feed joint 10 is connected to an external feeding device through a pipeline.

The computer is respectively connected to all the quantitative feeders 14 and the belt conveyor 1 by circuits. Workers control the quantitative feeders 14 and the belt conveyor by operating the computer or a pre-set computer program.

[0024] In order to prevent the quantitative feeder 14 from colliding with the material due to a large amount of material, the distance between the lower end of the quantitative feeder 14 and the belt of the belt conveyor 1 is not less than 30 cm, and the outlet end of the quantitative feeder 14 is located above the belt centerline of the belt conveyor 1.

[0025] A variety of materials are delivered to multiple silos 9 through a feeding device. When they are needed, the computer controls the quantitative feeder 14 and discharges the materials according to the pre-set formula and dosage. When the amount of materials discharged reaches the set value, the quantitative feeder 14 will stop discharging the materials, and the materials discharged from different silos 9 and the quantitative feeder 14 will fall on the belt conveyor 1.

[0026] The flat design and parallel distribution of the silo 9 greatly reduces the overall space occupied by the equipment. The silo 9, which was originally a cylindrical structure arranged on one side of the belt conveyor 1, is now designed to be distributed in parallel with a rectangular parallelepiped and arranged above the belt conveyor 1, thereby reducing the overall width of the equipment and greatly reducing the space occupied by the silo 9 along the conveying direction of the belt conveyor 1. It can be used in factories and workshops with smaller spaces, thereby improving the applicability of the utility model.

[0027] The utility model adopts a uniquely designed flat silo 9 structure, and the silo 9 is arranged above the belt conveyor 1. A plurality of parallel silos 9 are supported and arranged in parallel through a frame, which greatly reduces the space occupied by the silo 9 along the belt conveyor 1, and also reduces the space occupied perpendicular to the conveying direction of the belt conveyor 1. The silo 9 is arranged above the belt conveyor 1, and the material will fall onto the belt as soon as it leaves the outlet end of the quantitative feeder 14, which reduces the conveying distance of the material, further ensures the metering accuracy of the material discharge, and realizes the functions of reducing the space occupied by the silo 9, improving the space utilization rate, and shortening the discharge distance.
