Description

Technical Field

[0001] The utility model relates to the technical field of metering equipment, in particular to a volume metering device for vitrified microspheres. Background Art

[0002] There are various metering devices in the drying industry. Most devices use mass sensors to collect the weight of materials in the silo to know the amount of materials in the silo. However, for materials such as vitrified microspheres with typical low density and light weight, if general mass sensors are used, first, the weight collection error is relatively large, and if high-precision mass sensors are used, the cost is too high. Second, the vitrified microspheres piled up in the silo will show segregation. The heavy materials sink and the light materials are on the top, resulting in different amounts of materials in each packaged finished product bag although the weight of each weighing is the same. Therefore, this patent uses a radar level gauge to measure the accumulated horizontal height of the materials to calculate the material volume, thereby judging the amount of materials in the silo.

[0018] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0019] As Figures 1-3 shown, the vitrified microbead volume metering device of this embodiment includes a hopper 1, a cover plate 2 is arranged on the upper part of the hopper 1, a feeding port 3 is arranged on the cover plate 2, a height measuring device 4 is arranged on one side of the feeding port 3. The height measuring device 4 adopts a radar level gauge. A leveling device for leveling the height of the upper accumulation surface of the material is arranged in the hopper 1. The upper surface of the material is leveled by the leveling device to prevent the inaccurate height measured by the radar level gauge from resulting in inaccurate measurement data.

[0020] The leveling device includes a transmission shaft 5 arranged vertically. A leveling blade 6 is arranged at the lower part of the transmission shaft 5. A support device is arranged in the middle of the transmission shaft 5. The upper part of the transmission shaft 5 extends above the cover plate 2 and is connected to the drive source 7.

[0021] The transmission shaft 5 is installed at the central position of the hopper 1. The leveling blade 6 is located at the middle position of the hopper 1 and is provided in a plurality of numbers and evenly distributed along the circumferential direction of the transmission shaft 5.

[0022] The drive source 7 adopts a stepping motor.

[0023] The support device includes a bearing 8 sleeved on the transmission shaft 5. The bearing 8 is connected to the inner side wall of the hopper 1 through a cross brace 9. The number of cross braces 9 is multiple and they are evenly distributed along the circumferential direction of the bearing 8. A sealing cover 10 is arranged above the bearing 8 to prevent materials from falling into the bearing 8 and causing blockage. The support device can fix the transmission shaft 5 and prevent the transmission shaft 5 from deflecting.

[0024] During use, materials are added into the hopper 1 through the feeding port 2. After the addition is completed, the stepping motor drives the transmission rod 5 to rotate, and then drives the leveling blade 6 to level the upper part of the materials, removing the stacking angle generated during the falling process of the materials. After leveling, the radar level gauge is used to measure the stacking height of the materials to confirm the stored volume of the materials.

[0025] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The term "including" or any other similar term is intended to cover non-exclusive inclusion, so that a process, article, or device / equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes the elements inherent in these processes, articles, or devices / equipment.
