Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotor scale technology, specifically to a combined rotor scale housing. Background Technology
[0002] Rotary scales are efficient and accurate continuous metering devices widely used in material metering and batching processes in industries such as cement, chemicals, metallurgy, and food. Their structure mainly includes a frame, housing, top plate, bottom plate, rotor assembly, load cells, and speed sensors. Within the rotor scale's structure, the housing plays a crucial role in preventing dust leakage, isolating external interference, and supporting internal components, directly impacting the equipment's operational stability, safety, and service life.
[0003] In existing technology, the rotor scale housing is usually a complete cylindrical shell. When maintenance personnel perform regular internal maintenance on the rotor scale, the entire housing needs to be disassembled and then reassembled after the maintenance is completed. This makes the maintenance process of the rotor scale cumbersome and inconvenient to operate. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a modular rotor scale housing to solve the problem that the maintenance process of the rotor scale is cumbersome and inconvenient because the housing needs to be completely disassembled and reassembled during maintenance.
[0005] This utility model is achieved using the following technical solution: a combined rotor scale housing, comprising multiple arc-shaped plates, the ends of which are joined together to form a cylindrical shape, and a detachable fastening connection mechanism is provided at the end-to-end joint of two adjacent arc-shaped plates, wherein a hinge mechanism is connected to a portion of the fastening connection mechanism.
[0006] By setting up a hinge mechanism, the arc plate can be rotated after the fastening connection between two adjacent arc plates is disassembled, which is equivalent to opening a door on the shell. The internal structure of the rotor scale can be inspected through this door. After the inspection is completed, the arc plate can be rotated back and the shell can be fixed again by the fastening connection mechanism. This makes the inspection process simpler and more convenient.
[0007] Preferably, the fastening connection mechanism includes a first connecting plate fixedly installed at one end of the arc-shaped plate, and a second connecting plate fixedly connected to the mating end of the adjacent arc-shaped plate and the first connecting plate, wherein the first connecting plate and the second connecting plate are detachably fixedly connected. This detachable fixed connection between the first connecting plate and the second connecting plate facilitates the installation of the hinge mechanism.
[0008] Preferably, the hinge mechanism includes a first rotating arm fixedly mounted on a first connecting plate, and a second rotating arm fixedly connected to an adjacent second connecting plate, with the first rotating arm and the second rotating arm hinged together. The arrangement of the first and second rotating arms facilitates rotation between the curved plates.
[0009] Preferably, both the first and second rotating arms are L-shaped. The first rotating arm is fixedly connected to the side of the first connecting plate away from the adjacent second connecting plate, and the end of the first rotating arm away from the arc-shaped plate extends outward and points towards the adjacent second connecting plate. The second rotating arm is fixedly connected to the side of the second connecting plate away from the adjacent first connecting plate, and the end of the second rotating arm away from the arc-shaped plate extends outward and points towards the adjacent first connecting plate. The end of the first rotating arm pointing towards the second connecting plate is hinged to the end of the second rotating arm pointing towards the first connecting plate. The L-shaped first and second rotating arms ensure a more secure connection between the rotating arms and the connecting plates, and by extending the hinge point to the outside of the arc-shaped plate, the arc-shaped plate can rotate without obstruction.
[0010] Preferably, the number of arc-shaped plates is an even number greater than two, and the hinge mechanisms are spaced apart on the fastening connection mechanisms. By setting the number of arc-shaped plates to an even number greater than two, the number of fastening connection mechanisms will also be an even number. Furthermore, by setting the hinge mechanisms at intervals, each arc-shaped plate can be rotated and opened, which is more conducive to the comprehensive maintenance of the rotor scale.
[0011] Preferably, there are four curved plates and two hinge mechanisms. With four curved plates and two hinge mechanisms, each curved plate can be opened while maintaining a suitable space for each plate, making it more convenient to use.
[0012] Preferably, arc-shaped mounting plates are fixedly installed at both the upper and lower ends of the arc-shaped plate. The inner side of the mounting plate is flush with the inner side of the arc-shaped plate, and the outer side of the mounting plate extends outward. The mounting plate is also provided with several mounting holes. The mounting plates and mounting holes make it easier to install the arc-shaped plate.
[0013] Preferably, a number of reinforcing ribs are also fixedly installed on the outer wall of the arc-shaped plate, with the upper and lower ends of the reinforcing ribs being fixedly connected to the mounting plates on the upper and lower sides of the arc-shaped plate, respectively. The addition of reinforcing ribs makes the structure of the arc-shaped plate more stable, thereby improving the overall stability of the shell structure and extending the service life of the device.
[0014] Preferably, the mounting plate at the top of the arc-shaped plate is detachably and fixedly connected to a top plate, and the mounting plate at the bottom is detachably and fixedly connected to a bottom plate.
[0015] Preferably, the housing has multiple layers, with partition plates between adjacent layers. A top plate is detachably fixed to the mounting plate at the top of the top arc-shaped plate, and a bottom plate is detachably fixed to the mounting plate at the bottom of the bottom arc-shaped plate. The mounting plates at the bottom of the upper arc-shaped plates of the partition plates are detachably fixed to the partition plates, and the mounting plates at the top of the lower arc-shaped plates are detachably fixed to the partition plates. This multi-layered housing design allows the device to be used on multi-layer rotor scales. The arc-shaped plates of each rotor scale housing can be individually controlled to open and close, facilitating easier maintenance of the multi-layer rotor scale.
[0016] In summary, the beneficial effects of this utility model are as follows:
[0017] By using hinged mechanisms spaced apart on the fastening connection mechanism, an arc-shaped plate can be opened to observe the internal condition of the rotor scale when a malfunction occurs. If maintenance is required, the number of arc-shaped plates to be opened can be selected as needed, allowing repair of the internal structure of the rotor scale through the opening. After repair, the arc-shaped plate can be rotated to close again, and the closed first and second connecting plates, mounting plates, and their corresponding top, bottom, or partition plates can be re-secured. The entire maintenance process does not require disassembly and reassembly of the entire casing, making rotor scale maintenance more convenient and easier to operate. Attached Figure Description

Detailed Implementation
[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0026] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0027] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.
[0028] like Figure 1 , Figure 2 As shown, this utility model provides a combined rotor scale housing, including multiple arc-shaped plates 1. The ends of the multiple arc-shaped plates 1 are joined together to form a cylindrical shape. A detachable fastening connection mechanism is provided at the end-to-end joint of two adjacent arc-shaped plates 1, and a hinge mechanism 2 is connected to a part of the fastening connection mechanism.
[0029] Among these, some of the fastening mechanisms are connected to hinge mechanisms 2. This can be understood as at least one fastening mechanism having a hinge mechanism 2, and at least one fastening mechanism not having a hinge mechanism 2. For example, when there are two arc-shaped plates 1, then there are two fastening mechanisms and one hinge mechanism 2, in which case both arc-shaped plates 1 can be opened. When there are three arc-shaped plates 1, then the fastening mechanisms can be set to two or one.
[0030] The multiple arc-shaped plates 1 mentioned above are joined at their ends to form a cylindrical shape. In order to ensure the sealing of the rotor scale during use, sealing strips are provided on the mating surfaces of the arc-shaped plates 1.
[0031] When the number of arc-shaped plates 1 is an odd number other than one, there will be arc-shaped plates 1 on the shell that cannot be opened by rotation. Taking three arc-shaped plates 1 as an example, when there are two hinge mechanisms 2, the arc-shaped plate 1 with hinge mechanisms 2 at both ends cannot be opened independently by the hinge mechanism 2; when there is one hinge mechanism 2, the arc-shaped plate 1 without hinge mechanisms 2 at both ends also cannot be opened independently by the hinge mechanism 2. Therefore, the shell with an odd number of arc-shaped plates 1 has certain limitations in use. Therefore, in this embodiment, the number of arc-shaped plates 1 is an even number. When the number of arc-shaped plates 1 is two, there is also one hinge mechanism 2. When the number of arc-shaped plates 1 is more than two and is an even number, the hinge mechanisms 2 are spaced apart on the fastening connection mechanism, thereby allowing each arc-shaped plate 1 to be opened by the hinge mechanism 2.
[0032] Since the upper and lower parts of the arc-shaped plate 1 need to be connected to other parts of the machine body via bolts and nuts, when the number of arc-shaped plates 1 is too small, such as two, it is necessary to remove the bolts and nuts on one arc-shaped plate 1 (i.e., half of the shell) when it is necessary to check the internal condition of the rotor scale. This opening is large and the disassembly time is long. On the other hand, when the number of arc-shaped plates 1 is too large, such as eight, the opening area corresponding to each arc-shaped plate 1 is small. Removing the bolts and nuts on only one arc-shaped plate 1 to open the shell may result in poor visibility and incomplete observation, thus causing inconvenience for maintenance. Removing multiple arc-shaped plates 1 would make the process more complicated. Considering the above, in this embodiment, four arc-shaped plates 1 are set, and the angle corresponding to each arc-shaped plate 1 is 90 degrees. At this time, the opening size of a single arc-shaped plate 1 is most suitable. When the number of arc-shaped plates 1 is four, there are two hinge mechanisms 2.
[0033] like Figure 1 , Figure 3 , Figure 4 As shown, the fastening connection mechanism described above includes a first connecting plate 8 fixedly installed at one end of the arc plate 1, and a second connecting plate 9 fixedly connected to the mating end of the adjacent arc plate 1 and the first connecting plate 8. The first connecting plate 8 and the second connecting plate 9 can be detachably fixedly connected by bolts and nuts.
[0034] In actual use, if the height of a single arc plate 1 is relatively high, that is, the height of a single shell layer is relatively high, two layers of hinge mechanisms 2 can be set on one arc plate 1, so that the arc plate 1 can be more stable when rotating.
[0035] The hinge mechanism 2 described above includes a first rotating arm 3 fixedly mounted on the first connecting plate 8, and a second rotating arm 5 fixedly connected to the adjacent second connecting plate 9. The first rotating arm 3 and the second rotating arm 5 are hinged together. Specifically, both the first rotating arm 3 and the second rotating arm 5 are "L" shaped. The first rotating arm 3 is fixedly connected to the side of the first connecting plate 8 away from the adjacent second connecting plate 9. The end of the first rotating arm 3 away from the arc plate 1 extends outward and points towards the adjacent second connecting plate 9. The second rotating arm 5 is fixedly connected to the side of the second connecting plate 9 away from the adjacent first connecting plate 8. The end of the second rotating arm 5 away from the arc plate 1 extends outward and points towards the adjacent first connecting plate 8. One end of the first rotating arm 3 pointing towards the second connecting plate 9 is rotatably mounted with a pin 4. The other end of the pin 4 is rotatably connected to the end of the second rotating arm 5 pointing towards the first connecting plate 8.
[0036] Since the first connecting plate 8 and the second connecting plate 9 between two adjacent arc-shaped plates 1 are in close contact with each other, the hinge point for rotation between the two adjacent arc-shaped plates 1 is moved to the outside of the housing by the setting of the first rotating arm 3 and the second rotating arm 5, making it easier for the arc-shaped plate 1 to rotate out. In addition, in order to prevent the in-place first connecting plate 8 and the second connecting plate 9 from interfering with each other and preventing the arc-shaped plate 1 from rotating, the insertion holes on the first rotating arm 3 and the second rotating arm 5 can be made larger, or even oblong holes, that is, there is a gap between the pin shaft of the pin 4 and the insertion hole, and the pin 4 can move laterally in the insertion hole. In this way, when it is necessary to open the arc-shaped plate 1, after all the bolts and nuts on the arc-shaped plate 1 are removed, the arc-shaped plate 1 can be moved laterally outward first to avoid the mutual interference between the first connecting plate 8 and the second connecting plate 9, and then the arc-shaped plate 1 can be rotated.
[0037] Due to the limited thickness of the arc-shaped plate 1, direct connection to other machine bodies via the upper and lower sides of the arc-shaped plate 1 would result in limited installation stability. Therefore, arc-shaped mounting plates 6 are fixedly installed at both the upper and lower ends of the arc-shaped plate 1. The inner side of the mounting plate 6 is flush with the inner side of the arc-shaped plate 1, and the outer side of the mounting plate 6 extends outward. Several mounting holes for mounting bolts are also provided on the mounting plate 6.
[0038] Several reinforcing ribs 7 are fixedly installed on the outer wall of the arc-shaped plate 1. The upper and lower ends of the reinforcing ribs 7 are fixedly connected to the mounting plates 6 on the upper and lower sides of the arc-shaped plate 1, respectively. The setting of the reinforcing ribs 7 makes the structure of the arc-shaped plate 1 in this device more stable, thereby making the overall structure of the shell more stable and increasing the service life of this device.
[0039] like Figure 1 , Figure 5As shown, the body described above can be a top plate 10, a partition plate 11, or a bottom plate 12. When this device is used on a single-layer rotor scale, the housing is set as a single layer. The mounting plate 6 at the top of the arc plate 1 is detachably and fixedly connected to the top plate 10 by bolts and nuts, and the mounting plate 6 at the bottom of the arc plate 1 is detachably and fixedly connected to the bottom plate 12 by bolts and nuts.
[0040] like Figure 6 As shown, in the application of the rotor scale, the rotor scale can be mounted on the frame 13 of the rotor scale via the top plate 10. The top plate 10 is also equipped with a drive mechanism 14 for driving the internal impeller of the rotor scale to rotate.
[0041] When this device is used on a multi-layer rotor scale, the housing is provided in multiple layers, with a partition plate 11 between adjacent layers. The mounting plate 6 at the top of the top arc plate 1 is detachably and fixedly connected to the top plate 10 by bolts and nuts. The mounting plate 6 at the bottom of the bottom arc plate 1 is fixedly connected to the bottom plate 12 by bolts and nuts. The mounting plate 6 at the bottom of the upper arc plate 1 of the partition plate 11 is detachably and fixedly connected to the partition plate 11 by bolts and nuts. The mounting plate 6 at the top of the lower arc plate 1 of the partition plate 11 is detachably and fixedly connected to the partition plate 11 by bolts and nuts.
[0042] The operating principle of this device is as follows: When internal maintenance of the rotor scale is required, remove the bolts and nuts on the fastening mechanisms at both ends of one of the arc-shaped plates 1. Then, remove the bolts and nuts on the upper and lower mounting plates 6 of the arc-shaped plate 1. The arc-shaped plate 1 can then be rotated via the hinge mechanism 2 on one side to observe the internal structure of the rotor scale for maintenance. After maintenance, rotate the arc-shaped plate 1 in the opposite direction to close it again, and then reinstall the removed bolts and nuts to complete the installation of the housing. During maintenance, two arc-shaped plates 1 can also be opened as needed. It is important to note that these two arc-shaped plates 1 should ideally not be the same two plates on either side of the hinge mechanism 2. If the bolts and nuts on both sides of the arc-shaped plates 1 of one hinge mechanism 2 are removed, these two arc-shaped plates 1 will completely detach from the rotor scale, negating their convenience.
[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
