Abstract
Description
Technical Field
[0001] This application belongs to the field of flange technology, specifically relating to a flange structure and a feeding device. Background Technology
[0002] In steel production areas, solid fuels are often transported to storage tanks via belt conveyor systems. The material falls from the end of the belt into a chute, and the outlet of the chute is connected to the inlet of the storage tank via a flange. The flange is equipped with multiple bolts. Because the material is transported by belt and has a horizontal speed, it collides with the chute when it comes into contact with it, which puts stress on the flange between the chute and the storage tank. The bolts will bear shear force. Over a long period of use, the bolts may deform or break due to stress, causing the flange connection to become loose. Summary of the Invention

[0025] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0026] Please see Figures 1-3According to a first aspect of this application, a flange structure is provided, including a first flange 100, a second flange 200, and at least one limiting member 300. The first flange 100 and the second flange 200 are mated, and the first flange 100 and the second flange 200 are connected by bolts to form a flange for connecting tubular components. In this embodiment, the flange refers to the first flange 100 and the second flange 200 in the connected state, and at least one limiting member 300 is disposed on the flange. The limiting member 300 has a main body 310 and a first column 320 and a second column 330 disposed opposite to each other at both ends of the main body 310. The first column 320 is connected to the end face of the first flange 100 facing away from the second flange 200, and the second column 330 is connected to the end face of the second flange 200 facing away from the first flange 100. That is, the limiting member 300 has a frame structure and can restrict the relative movement between the first flange 100 and the second flange 200. In other words, by setting the limiting member 300, the relative movement between the first flange 100 and the second flange 200 is improved. The connection tightness is ensured by the fact that the limiting member 300 itself has a certain strength, meaning that the position between the main body 310, the first column 320, and the second column 330 is not easily changed. Therefore, the connection between the limiting member 300 and the first flange 100 and the second flange 200 can reduce the possibility of misalignment between the first flange 100 and the second flange 200 under different forces, thereby reducing the shear force on the bolts, reducing the possibility of bolt deformation or breakage, improving the tightness of the flange during long-term use, and extending its service life.
[0027] Please see Figure 1 and Figure 3 In some embodiments, the end face of the first flange 100 facing away from the second flange 200 is provided with at least one first limiting groove 110, and the end face of the second flange 200 facing away from the first flange 100 is provided with at least one second limiting groove 210. The first column 320 can be engaged with the first limiting groove 110, and the second column 330 can be engaged with the second limiting groove 210.
[0028] The first limiting groove 110 is provided on the end face of the first flange 100. It can be understood that the groove wall of the first limiting groove 110 has an angle with the end face of the first flange 100. Similarly, the groove wall of the second limiting groove 210 also has an angle with the second flange 200. The first column 320 is connected to the first flange 100 by snapping with the first limiting groove 110, and the second column 330 is connected to the second flange 200 by snapping with the second limiting groove 210. After the first flange 100 and the second flange 200 are connected by bolts to form a flange, the first column 320 abuts against the groove wall of the first limiting groove 110 and the second column 330 abuts against the groove wall of the second limiting groove 210. The first flange 100 needs to overcome the anti-deformation force between the main body 310 and the first column 320 in order to generate relative movement between the first flange 100 and the second flange 200. That is, the limiting member 300 can restrict the mutual movement between the first flange 100 and the second flange 200 and reduce the shear force borne by the bolts.
[0029] Of course, when the first flange 100 is provided with a first limiting groove 110 and the second flange 200 is provided with a second limiting groove 210, the distance between the first column 320 and the second column 330 can be equal to the distance between the bottom of the first limiting groove 110 and the bottom of the second limiting groove 210 on the flange, so as to improve the stability of the limiting member 300.
[0030] In some embodiments, the length direction of the first limiting groove 110 is arranged radially along the first flange 100; the length direction of the second limiting groove is arranged radially along the second flange 200. This makes the stress capacity of the two opposite groove walls of each individual first limiting groove 110 or second limiting groove 210 relatively balanced, reducing the occurrence of deformation of the first flange 100 and the second flange 200 due to the limiting member 300.
[0031] Please see Figure 1 The first flange is provided with at least three first limiting grooves 110, which are arranged around the axial circumference of the first flange 100, and the included angle between two adjacent first limiting grooves 110 is not greater than 180°; the second flange is provided with at least three second limiting grooves 210, which are arranged around the axial circumference of the second flange 200, and the included angle between two adjacent second limiting grooves 210 is not greater than 180°.
[0032] If the included angle between two adjacent first limiting grooves 110 is no greater than 180°, then when setting the flange, regardless of the direction from which the impact force received by the hopper or other material-carrying structure connected to the first flange 100 comes, at least two limiting members 300 can abut against the groove wall of the first limiting groove 110, thereby limiting the displacement of the first flange 100 relative to the second flange 200. The cooperation between the second limiting groove 210 and the limiting member 300 is similar. In some embodiments, at least three first limiting grooves 110 are equally spaced, that is, the included angle between two adjacent first limiting grooves 110 is no greater than 120°. In this case, the limiting effect of multiple limiting members 300 on the first flange 100 and the second flange 200 is better. Of course, the second limiting grooves 210 on the second flange 200 are also equally spaced.
[0033] In some embodiments, the opposite side walls of the first column 320 abut against the opposite two groove walls of the first limiting groove 110; the opposite side walls of the second column 330 abut against the opposite two groove walls of the second limiting groove 210. This improves the limiting effect of the multiple limiting members 300 on the first flange 100 and the second flange 200. Specifically, the first column 320 and the first limiting groove 110, as well as the second column 330 and the second limiting groove 210, are interference fits to improve the tightness of the connection between the limiting members 300 and the first flange 100 and the second flange 200. Meanwhile, the first limiting groove 110 and the second limiting groove 210 are both rectangular grooves, and the first column 320 and the second column 330 are both regular square prisms.
[0034] In some embodiments, a first bevel is provided at the junction of the first column 320 and the first flange 100; a second bevel is provided at the junction of the second column 330 and the second flange 200.
[0035] To further improve the connection tightness between the limiting member 300 and the flange, after the limiting member 300 is installed on the flange, the first column 320 can be connected to the first flange 100, and the second column 330 can be connected to the second flange 200 by welding. The first bevel and the second bevel can increase the welding area and improve the connection tightness. Specifically, if the first flange 100 does not have the first limiting groove 110 and the second flange 200 does not have the second limiting groove 210, the limiting member 300 can still be connected to the flange by welding. In this case, the minimum distance between the first column 320 and the second column 330 is equal to the sum of the thicknesses of the first flange 100 and the second flange 200. In this case, the first bevel is located on the end face of the first column 320 facing the second column 330, and the second bevel is located on the end face of the second column 330 facing the first column 320. Of course, when the first flange 100 is provided with a first limiting groove 110 and the second flange 200 is provided with a second limiting groove 210, the tightness of the connection between the limiting member 300 and the flange can also be further improved by welding. In this case, the first bevel is located on the side wall of the first column 320 and is flush with the end face of the first flange 100, and the second bevel is located on the side wall of the second column 330 and is flush with the end face of the second flange 200, so as to facilitate welding.
[0036] In some embodiments, the minimum distance between the first column 320 and the second column 330 is not greater than the sum of the thicknesses of the first flange 100 and the second flange 200, so as to ensure that the limiting member 300 can be disposed on the flange.
[0037] In some embodiments, the first column 320 and the second column 330 are arranged in parallel. In this case, the contact area or connection area between the limiting member 300 and the first flange 100 and the second flange 200 is large, the limiting member 300 is not easy to separate from the flange, the bolts in the flange structure are subjected to small shear force, and the flange structure is not easily damaged.
[0038] Please see Figure 4 In a second aspect of this application, a feeding device is provided, including a belt, a chute 400, a storage tank 500, and a flange structure. The inlet of the chute 400 is located at the outlet end of the belt. The outlet of the chute 400 is connected to a first flange 100, and the inlet of the storage tank 500 is connected to a second flange 200. At least one limiting member 300 is provided on both the first flange 100 and the second flange 200. The limiting member 300 is capable of providing a force toward the belt to the first flange 100. The limiting member 300's ability to provide a force toward the belt to the first flange 100 restricts the relative movement between the first flange 100 and the second flange 200, weakens shear force, reduces the probability of bolt damage, and improves the service life of the flange structure.
[0039] As the material moves along the belt, it will impact the chute 400 after falling into it. At this time, the force exerted by the material on the chute 400 will have a component force in the same direction as the material being transported by the belt. Generally, the material will collide with the side of the chute 400 away from the belt. Therefore, in some embodiments, the number of limiting members 300 on the side of the flange structure away from the belt is greater than the number of limiting members 300 on the side of the flange structure closer to the belt, in order to specifically improve the shear resistance of the side of the flange away from the belt.
