An on-line material distribution device and bin

Abstract

An online material distribution device and hopper belong to the field of material storage technology. The online material distribution device includes a hanger with a receiving hopper fixed at its bottom. A material distribution cone is rotatably connected to the receiving hopper and located below the receiving hopper. Several inclined baffles are fixedly arranged on the surface of the material distribution cone. Several guide troughs are fixedly arranged at intervals on the bottom periphery of the material distribution cone. The guide troughs are arc-shaped, and several discharge ports are spaced apart on both side walls of the guide troughs. The arc-shaped guide troughs can change the material conveying trajectory by their own curvature, allowing the material to flow along an arc-shaped path within the guide troughs. This not only disperses the impact force of the material and avoids local accumulation but also expands the material conveying coverage area. At the same time, the collision between the baffles and the falling material drives the material distribution cone to rotate. Combined with the dynamic conveying of the arc-shaped guide troughs and the setting of discharge ports on both sides, it is possible to achieve uniform material distribution over a large area in multiple directions, greatly improving the efficiency and uniformity of material distribution.

Description

Technical Field

[0001] This utility model relates to the field of material storage technology, and in particular to an online material distribution device and a silo. Background Technology

[0002] In Roche's dry desulfurization and denitrification technology, the silo is a key piece of equipment for storing desulfurization and denitrification adsorbents (such as activated carbon, desulfurizing agents, etc.). The silo is usually a cylindrical or conical cylinder with a feed inlet at the top and a maintenance manhole on the side wall.

[0003] During use, the desulfurization and denitrification adsorbent enters the silo from the center of the top inlet. Under the action of free fall, the desulfurization and denitrification adsorbent naturally accumulates from bottom to top, resulting in a larger accumulation of desulfurization and denitrification adsorbent in the middle area than in the surrounding area. This affects the storage and use of the desulfurization and denitrification adsorbent. To solve the above problems, a material distribution device is usually installed in the silo to distribute the desulfurization and denitrification adsorbent to all sides.

[0004] Existing material distribution devices are divided into two categories. One is a fixed conical structure, which has a limited material distribution range. The other is a guide trough installed on the periphery of the conical structure, which extends the material distribution range. The guide trough is a strip-shaped U-shaped channel with a discharge port on the side wall. The discharge points of the strip-shaped U-shaped channel are easily distributed in a radial straight line in the hopper, causing the material in the same radius area to concentrate at a specific angle, forming a strip-shaped accumulation zone with poor uniformity. Utility Model Content

[0005] To address the technical problem in the background art where the unloading points of existing strip-shaped U-shaped troughs tend to be arranged radially in a straight line within the silo, resulting in material being concentrated at a specific angle within the same radius area, forming a strip-shaped accumulation zone with poor uniformity, this utility model provides an online material distribution device.

[0006] The technical solution of this utility model is as follows: This utility model provides an online material distribution device, including a hanger with a receiving hopper fixed at the bottom. A material distribution cone is rotatably connected to the receiving hopper and located below it. Several inclined baffles are fixedly arranged on the surface of the material distribution cone. The receiving hopper can receive materials conveyed from above. The material distribution cone rotates under the collision of the baffles and the falling material, thereby achieving dynamic material dispersion. Several guide grooves are fixedly arranged at intervals on the bottom periphery of the material distribution cone. The guide grooves are arc-shaped, and several discharge ports are spaced apart on both side walls. The arc-shaped guide grooves can change the material conveying trajectory using their curvature, allowing the material to flow along an arc-shaped path within the guide groove. This not only disperses the impact force of the material and avoids local accumulation but also expands the material conveying coverage area. Simultaneously, the collision of the baffles and the falling material drives the material distribution cone to rotate. Combined with the dynamic conveying of the arc-shaped guide grooves and the arrangement of discharge ports on both sides, multi-directional and large-area uniform material distribution can be achieved, significantly improving distribution efficiency and uniformity.

[0007] Preferably, the discharge ports on the side walls of the guide chute are arranged opposite each other, so that when the material flows along the arc-shaped guide chute, it can be discharged from symmetrical positions on both sides, avoiding the material from accumulating on one side, further improving the symmetry and uniformity of the fabric, and ensuring a more balanced material distribution.

[0008] Preferably, a guide plate is fixedly provided at each discharge port. The guide plate is fixedly installed inside the guide trough and has an angle with the corresponding side wall of the guide trough. The guide plate can guide the material in the guide trough so that some of the material can be discharged outward from the discharge port.

[0009] Preferably, there is a gap between the two oppositely arranged guide plates, allowing some material to pass through the gap, increasing the material discharge path, and preventing all material from being discharged outward from a single discharge port.

[0010] Preferably, the baffle is inclined in the direction of the curvature of the guide trough, which can efficiently convert the driving force generated by the collision into the rotational power of the cloth cone, so that the rotation of the cloth cone meets the material conveying requirements of the arc-shaped guide trough and improves the overall operating efficiency of the device.

[0011] Preferably, the angle between the baffle and the horizontal plane is 15°-20°, which ensures that sufficient rotational power is provided to the fabric cone without causing insufficient or excessive collision force due to excessive or excessive angle, thus ensuring stable rotation of the fabric cone and achieving uniform fabric distribution in conjunction with the arc-shaped guide groove.

[0012] Preferably, the baffles are fixedly arranged at intervals along the circumference on the surface of the fabric cone to form evenly distributed collision points, making the collision between the falling material and the baffles more uniform, thereby driving the fabric cone to rotate smoothly, avoiding rotational swaying caused by uneven collisions, ensuring that the arc-shaped guide chute can stably transport materials, and improving the overall stability of the fabric.

[0013] Preferably, the receiving hopper has an open structure at the top and bottom, and a support frame is fixedly installed inside the receiving hopper. A fixing ring is fixedly installed at the middle position of the support frame. The fixing ring is rotatably connected to the material cone disc through a rotating shaft. The cooperation between the fixing ring and the rotating shaft ensures that the material cone disc can rotate stably under the driving force generated by the collision between the baffle and the falling material, reducing the shaking during the rotation process and ensuring that the arc-shaped guide chute can continuously and stably perform the material conveying function.

[0014] Preferably, the spacing between the discharge ports on the same side wall of the guide trough increases with the curvature. Combined with the rotational motion, this can create denser material distribution points in different radius areas, avoiding the problem of local material overlap or sparseness caused by the linear distribution of long strip guide troughs.

[0015] This utility model provides a silo, including a silo body, in which an online material distribution device is installed to achieve uniform material distribution, avoid material accumulation or uneven distribution at the silo body outlet, improve the silo's discharge efficiency and the uniformity of subsequent material processing, and enhance the silo's practicality.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are: 1. The guide chute is an arc-shaped chute, with several discharge ports spaced apart on both sides of the guide chute. The arc-shaped guide chute can change the material conveying trajectory by its own curvature, so that the material flows along the arc path in the guide chute. This not only disperses the impact force of the material and avoids local accumulation, but also expands the material conveying coverage area. At the same time, the collision between the baffle and the falling material drives the material distribution cone to rotate. Combined with the dynamic conveying of the arc-shaped guide chute and the setting of the discharge ports on both sides, it can realize the uniform distribution of material in multiple directions and over a large area, which greatly improves the distribution efficiency and uniformity.

[0017] 2. The spacing between the discharge ports on the same side wall of the guide chute increases with the curvature. Combined with the rotational motion, it can form a denser distribution point in different radius areas, avoiding the problem of local material overlap or sparseness caused by the linear distribution of long strip guide chute.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Example 1 In a typical embodiment of this utility model, such as Figures 1-2 As shown, an online material distribution device is proposed, including: a hanger 1, a receiving hopper 2, a material distribution cone 5, a guide trough 7, and a rotating shaft 11. The hanger 1 is used for the overall hoisting of the material distribution device. The receiving hopper 2 is fixedly connected to the hanger 1 and is fixedly installed at the inlet of the silo body via the hanger 1. The top center of the material distribution cone 5 is fixedly connected to the rotating shaft 11. The rotating shaft 11 is vertically arranged, and its top end is rotatably connected to the receiving hopper 2. The material distribution cone 5 is located directly below the receiving hopper 2 for receiving and distributing the desulfurization and denitrification adsorbent. Several guide troughs 7 are provided, and several guide troughs 7 are fixedly arranged at intervals on the bottom periphery of the material distribution cone 5. Several baffles 6 are fixedly provided on the surface of the material distribution cone 5. The baffles 6 are inclined so that the collision between the desulfurization and denitrification adsorbent and the baffles 6 drives the rotation of the material distribution cone 5 without the need for an additional power device. In turn, the material distribution cone 5 drives the guide trough 7 to rotate around the axis to complete the uniform distribution.

[0022] Specifically, the material distribution cone 5 has a conical structure, and the top diameter of the material distribution cone 5 is smaller than its bottom diameter; the material guide trough 7 is an arc-shaped trough with a U-shaped cross-section, allowing the desulfurization and denitrification adsorbent to flow inside the material guide trough 7. Several discharge ports 9 are spaced apart on both sides of the material guide trough 7 for discharging the desulfurization and denitrification adsorbent.

[0023] To further improve the installation stability of the material guide trough 7, a support rod can be installed at the bottom of the material distribution cone 5, and the bottom of the material guide trough 7 can be supported by the support rod. The specific selection can be made according to actual needs, and no further restrictions are imposed here.

[0024] In this embodiment, the discharge ports 9 on the two side walls of the material guide trough 7 are arranged opposite to each other. Each discharge port 9 is fixed with a guide plate 8 by welding. The guide plate 8 has an angle with the corresponding side wall of the material guide trough 7, and the angle is acute. The guide plate 8 is fixedly installed inside the material guide trough 7 to guide part of the desulfurization and denitrification adsorbent so that it is discharged outward from the discharge port 9.

[0025] It should be noted that there is a gap between the two oppositely arranged guide plates 8 to allow the desulfurization and denitrification adsorbent to pass through, so as to ensure that the desulfurization and denitrification adsorbent can move along the feed trough 7 and be discharged outward through the discharge port 9 at different positions.

[0026] In this embodiment, the spacing between the outlets 9 on the same side wall of the guide trough 7 increases with the curvature. Combined with the rotational motion, it can form denser material distribution points in different radius areas, avoiding the problem of local material overlap or sparseness caused by the linear distribution of long strip guide troughs.

[0027] like Figure 1 As shown, the baffle 6 is inclined in the direction of the arc of the guide trough 7. The baffle 6 is fixedly installed on the surface of the feeding cone 5 at intervals along the circumference. In order to increase the contact area between the baffle 6 and the material, the surface of the baffle 6 can also be set to be arc-shaped.

[0028] In this embodiment, the angle between the baffle 6 and the horizontal plane is 15°-20° to ensure full contact with the desulfurization and denitrification adsorbent. The collision between the desulfurization and denitrification adsorbent and the baffle 6 is used to drive the rotation of the fabric cone 5.

[0029] The hanger 1 includes a fixing plate 12 and fixing rods 13. The fixing plate 12 is an annular plate with several through holes spaced along its circumference. The fixing plate 12 can be fixedly installed in the hopper by bolts. Several fixing rods 13 are provided and fixedly installed on the lower surface of the fixing plate 12 by welding. The bottom end of the fixing rod 13 is fixedly connected to the receiving hopper 2 by welding, thereby fixing the position of the receiving hopper 2.

[0030] It is understood that in other embodiments, the fixing plate 12 can also be fixedly connected to the hopper body by welding. The specific fixing method can be selected according to the actual design requirements, and no further restrictions are imposed here.

[0031] like Figure 2 As shown, the receiving hopper 2 has an open structure at the top and bottom. A support frame 3 is fixed inside the receiving hopper 2 by welding. The support frame 3 has a rod-shaped structure. A fixing ring 4 is fixed at the middle position of the support frame 3. The fixing ring 4 is coaxially arranged with the receiving hopper 2. A bearing 10 is fixed inside the fixing ring 4. The inner ring of the bearing 10 is fixedly connected to the rotating shaft 11, thereby realizing the rotational connection between the rotating shaft 11 and the receiving hopper 2.

[0032] In this embodiment, the rotating shaft 11 is fixedly connected to the top center of the material distribution cone 5, so that the material distribution cone 5 is located directly below the receiving hopper 2, so as to ensure that the desulfurization and denitrification adsorbent can fall onto the material distribution cone 5, so as to achieve uniform material distribution.

[0033] Example 2 In another typical embodiment of this utility model, a hopper is proposed, including a hopper body and an online material distribution device. The top center of the hopper body is provided with a material inlet. The online material distribution device is fixedly installed inside the hopper body by a hanger 1 and is located directly below the material inlet. The receiving hopper 2 is coaxially arranged with the material inlet.

[0034] In actual use, the desulfurization and denitrification adsorbent is put into the silo through the feed inlet. The desulfurization and denitrification adsorbent first enters the receiving hopper 2 and collects. Then, it is guided to the distribution cone 5 through the receiving hopper 2. The desulfurization and denitrification adsorbent collides with the baffle 6 on the distribution cone 5 to drive the distribution cone 5 to rotate around the axis. Part of the desulfurization and denitrification adsorbent on the distribution cone 5 slides directly down, and the other part of the desulfurization and denitrification adsorbent slides into the guide trough 7 to be guided and distributed through the guide trough 7. The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
