Material storage bin based on a discharge assembly to control impulse

Abstract

This utility model relates to a storage bin with impulse control based on a discharging component, belonging to the technical field of storage equipment. The storage component includes a bin body with an inlet at the top and an outlet at the bottom, the outlet being a cylindrical outlet. The cylindrical outlet defines a first direction and a second direction, with the axial direction of the cylindrical outlet being the second direction and the radial direction being the first direction. It controls material feeding through the coordinated operation of two discharging gates located at the bottom of the outlet. One gate has a larger shielding area than the other, allowing for rapid discharging, while the smaller gate partially closes at the end of the discharging process to reduce the flow area, thereby precisely controlling and reducing the material impulse and improving weighing accuracy. Furthermore, this utility model uses a cylinder-driven linkage mechanism to move the discharging plate, resulting in high stability of the mechanical transmission structure.

Description

Technical Field

[0001] This utility model relates to the field of material storage equipment technology, and in particular to a material storage bin based on the control of impulse by a material dispensing component. Background Technology

[0002] With the development of asphalt pavement recycling technology, the storage and metering of hot recycled asphalt mixtures during the production process have become increasingly critical. These materials have high temperatures and high viscosity, and are often temporarily stored and weighed using specialized storage silos.

[0003] In related technologies, pneumatic or mechanical gates are often installed at the outlet to control material feeding.

[0004] However, there are still obvious limitations:

[0005] Due to the unstable material flow of hot recycled materials, the impulse fluctuation during the weighing process is large, which seriously affects the weighing accuracy and production efficiency. Utility Model Content

[0006] In response to the shortcomings of the existing production technology, the applicant provides a storage bin based on the control of impulse by a feeding component, thereby controlling the impulse and reducing weighing errors.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A storage bin based on a discharge assembly for controlling impulse, comprising:

[0009] A material storage assembly, comprising a hopper body, wherein the hopper body has an inlet at the top and an outlet at the bottom, and the outlet is a cylindrical outlet.

[0010] The first direction and the second direction are defined by the cylindrical discharge port, wherein the axial direction of the cylindrical outlet of the discharge port is the second direction, and the radial direction is the first direction;

[0011] A feeding assembly is disposed at the bottom of the discharge port along the axial direction. The feeding assembly includes a first feeding gate and a second feeding gate arranged side by side in a first direction.

[0012] The first discharge gate includes a first discharge plate and a first drive unit disposed on both sides thereon. The first drive unit includes a first drive cylinder, a first cylinder seat, a first swing arm and a first connecting rod. The first cylinder seat is fixed to the outer wall of the discharge port. The first drive cylinder is disposed on the first cylinder seat and its output end is connected to the first swing arm. The first swing arm is connected to the first discharge plate through the first connecting rod.

[0013] The second discharge gate includes a second discharge plate and a second drive unit disposed on both sides thereon. The second drive unit includes a second drive cylinder, a second cylinder seat, a second swing arm and a second connecting rod. The second cylinder seat is fixed to the outer wall of the discharge port. The second drive cylinder is disposed on the second cylinder seat and its output end is connected to the second swing arm. The second swing arm is connected to the second discharge plate through the second connecting rod.

[0014] The first and second feeding plates together block or avoid the discharge port.

[0015] As a further improvement to the above technical solution:

[0016] In one embodiment, the orthographic projection of the first feeding plate body in the second direction forms a first outer contour, and the orthographic projection of the second feeding plate body in the second direction forms a second outer contour; the length of the first outer contour in the first direction is greater than the length of the second outer contour in the first direction.

[0017] In one embodiment, the chamber is a tapered cavity structure that tapers from top to bottom in the second direction.

[0018] In one embodiment, the first drive cylinder drives the first swing arm to rotate, and drives the first discharge plate to move through the first connecting rod, thereby blocking or avoiding a portion of the discharge port area.

[0019] In one embodiment, the second drive cylinder drives the second swing arm to rotate, and drives the second discharge plate to move through the second connecting rod, thereby blocking or avoiding a portion of the discharge port area.

[0020] In one embodiment, the feeding assembly has a first state in which both the first feeding plate and the second feeding plate avoid the discharge port, thereby achieving rapid feeding.

[0021] In one embodiment, the feeding assembly further has a second state in which the first feeding plate avoids the discharge port, and the second feeding plate blocks a portion of the discharge port to control the discharge impulse.

[0022] In one embodiment, the first discharge gate and the second discharge gate are arranged side by side in a first direction.

[0023] In one embodiment, the first driving unit and the second driving unit have the same structure.

[0024] The beneficial effects of this utility model are as follows:

[0025] This utility model has a compact structure. Through the coordinated operation of two discharge gates, the discharge process is divided into two states: "rapid discharge" and "controlled impulse". At the end of the discharge, one discharge gate is kept open to ensure the basic flow channel, while the other discharge gate is partially closed to significantly reduce the effective flow area of ​​the outlet. This greatly suppresses the falling speed and impact force of the material, thereby fundamentally reducing the weighing error.

[0026] This utility model also has the following advantages:

[0027] The two feeding plates of this utility model are not symmetrically designed, with one having a larger shielding area than the other. The larger plate is mainly responsible for controlling the flow of the main body, while the smaller plate is used to control the final counter-current flow. This allows the equipment to maintain efficient material output for most of the time, with intervention only required in the final critical stage, perfectly balancing the two usually difficult-to-achieve indicators of production efficiency and metering accuracy.

[0043] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0044] like Figures 1-5 The accompanying drawing shows a schematic diagram of the structure of a storage bin based on the control of impulse by a feeding component in one embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0045] This application provides a storage bin based on the impulse control of the discharge component, including a storage component 100 and a discharge component 200.

[0046] In some embodiments, the storage assembly 100 is the main part of material storage, including a silo 120. The top of the silo 120 is provided with an inlet 110 for receiving incoming materials; its bottom is tapered and connected to an outlet 130, which is specifically designed as a cylindrical outlet.

[0047] Understandably, in order to better define the orientation, two directions are defined based on the cylindrical discharge port 130: the radial direction is defined as the first direction, and the axial direction is defined as the second direction.

[0048] Furthermore, the hopper 120 is configured in a conical cavity structure that gradually narrows inward from top to bottom in the second direction. This structure facilitates the convergence of materials towards the central discharge port 130 under the action of gravity.

[0049] In some embodiments, the material discharge assembly 200 is used to control material discharge and is installed directly below the discharge port 130 along the second direction;

[0050] Furthermore, the feeding assembly 200 includes a first feeding gate 210 and a second feeding gate 220 arranged side by side in a first direction.

[0051] The specific structure of the first discharge gate 210 is as follows:

[0052] It includes a first discharge plate 211 for directly blocking or avoiding a portion of the discharge port 130, and two sets of first drive units are symmetrically arranged on both sides of the first discharge plate 211.

[0053] Furthermore, each first drive unit includes a first drive cylinder 212, which is securely mounted on the outer wall of the discharge port 130 via a first cylinder seat 213. The piston rod output end of the first drive cylinder 212 is hinged to one end of a first swing arm 214; the other end of the first swing arm 214 is hinged to the corresponding side of the first discharge plate 211 via a first connecting rod 215.

[0054] When the piston rod of the first drive cylinder 212 extends or retracts, it drives the first swing arm 214 to rotate around its fulcrum. The rotation of the first swing arm 214 then pushes or pulls the first discharge plate 211 through the first connecting rod 215, causing it to move in a plane parallel to the bottom surface of the discharge port 130, thereby blocking or avoiding a portion of the discharge port 130.

[0055] The second discharge gate 220 is structurally similar to the first discharge gate 210 but functionally different. The second discharge gate 220 includes a second discharge plate 221 and two sets of second drive units disposed on its two sides. Each set of second drive units includes a second drive cylinder 222, which is fixed to the outer wall of the discharge port 130 via a second cylinder seat 223. The piston rod output end of the second drive cylinder 222 is hinged to one end of a second swing arm 224, and the other end of the second swing arm 224 is hinged to the corresponding side of the second discharge plate 221 via a second connecting rod 225. Its driving principle is the same as that of the first discharge gate 210: the second drive cylinder 222 drives the second swing arm 224 to rotate, and then the second connecting rod 225 drives the second discharge plate 221 to move, so as to control its blocking or avoidance of another part of the discharge port 130.

[0056] The first feeding plate 211 and the second feeding plate 221 work together to fully open, partially open or fully close the entire cylindrical discharge port 130.

[0057] It should be particularly noted that the length of the first outer contour formed by the orthographic projection of the first feeding plate 211 in the second direction is greater than the length of the second outer contour formed by the orthographic projection of the second feeding plate 221 in the second direction. This means that the inherent occlusion area of ​​the first feeding plate 211 is greater than that of the second feeding plate 221.

[0058] The operation of the feeding assembly 200 includes two main states:

[0059] like Figure 4 The first state shown is: the first drive cylinder 212 and the second drive cylinder 222 act simultaneously, driving the first discharge plate 211 and the second discharge plate 221 to move to a position that completely avoids the discharge port 130. At this time, the discharge port 130 is fully open, realizing the rapid and large-flow discharge of materials.

[0060] like Figure 5 The second state shown is as follows: At the end of the discharge period, when it is necessary to precisely control the flow rate to reduce the impulse, the first discharge gate 210 remains open (the first discharge plate 211 avoids it), while the second drive cylinder 222 drives the second discharge plate 221 to move in the opposite direction, so that it partially blocks the discharge port 130, thereby significantly reducing the effective outflow area, effectively suppressing the material flow rate and impact force, achieving precise control, and greatly improving the final weighing accuracy.

[0061] In summary, the present invention has a reasonable structure. By coordinating the opening and closing of two feeding plates with different shielding area sizes, the impulse is reduced at the end of the feeding process, effectively solving the technical problem of large impulse and low weighing accuracy of recycled materials during the weighing and feeding process.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
