Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a vibration testing device. Background Technology

[0002] In the air separation field, packing material is typically loaded into packed towers before transportation. The packed towers are then transported horizontally to the target customer, where they are vertically erected and put into use. However, during use at the target customer's location, operators have observed a decrease in the mass transfer efficiency of the packing material compared to pre-transport laboratory tests. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect of poor performance of packing material in packed towers due to transportation in the prior art, and to provide a vibration testing device.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention provides a vibration testing device for simulating and testing the volume change of loose packing material during transportation. The vibration testing device includes a body, which includes a shell and a receiving cavity disposed within the shell for accommodating the loose packing material. The body facilitates the observation and measurement of the volume change of the loose packing material within the receiving cavity.

[0006] In this solution, the vibration testing device is used to simulate the volume change of the packing material during transportation. The vibration testing device includes a main body, which includes a shell and a receiving cavity inside the shell for accommodating the packing material. When vibration testing is performed, the main body can easily observe and measure the volume change of the loosely packed packing material in the receiving cavity. Operators can know the volume change of the loosely packed packing material before and after vibration, and thus obtain the void situation caused by the re-accumulation of the loosely packed packing material during transportation. This allows for timely detection of the re-accumulation problem of the loosely packed packing material before or during transportation, facilitating rapid handling and improving the performance of the loosely packed packing material after transportation.

[0007] Preferably, at least a portion of the shell is made of a transparent material through which the height of the internal random packing can be observed, and the transparent material is provided with a scale to display the changes in the height of the random packing.

[0008] In this solution, at least a portion of the shell is made transparent, allowing the height of the internal random packing to be observed through the transparent material. The transparent material is provided with a scale to display the changes in the height of the random packing, enabling operators to observe the changes in the height of the random packing inside the shell through the transparent portion of the shell, and to more accurately determine the specific height of the random packing through the scale on the transparent material.

[0009] Preferably, the vibration testing device further includes a separator connected to the main body, which divides the receiving cavity into at least two sub-cavities, such that the sub-cavities are used to accommodate different types of random packing fillers. The separator has a handle on its edge, which is located on the outside of the housing to facilitate the installation of the separator.

[0010] In this design, the vibration testing device further divides the housing into multiple compartments using partitions. Different compartments accommodate different types of random packing material, allowing for simultaneous vibration testing of various types of random packing material, thus improving testing efficiency and reducing repetitive testing operations. Handles located on the outer edge of the housing are provided along the edge of the partitions, making it easier for operators to hold and operate the device, and facilitating the installation and removal of the partitions.

[0011] Preferably, the housing is provided with a slot that matches the shape of the separator, and the separator can be inserted into the slot to divide the receiving cavity into at least two compartments in the horizontal direction for placing different types of bulk packing.

[0012] In this design, by inserting the separator into a slot on the housing that matches its shape, the receiving cavity can be easily divided into at least two compartments in the horizontal direction to accommodate different types of bulk packing material, making the installation and removal of the separator more convenient. Setting the slot and separator to match their shapes also allows for more accurate insertion of the separator, facilitating its positioning.

[0013] Preferably, in use, the slot is located at the upper end of the housing and is arranged vertically, so that the partition is inserted into the slot vertically.

[0014] And / or, the housing further includes a fastener capable of fixing the relative position of the separator to the housing.

[0015] In this design, during use, the slot is positioned at the top of the housing and vertically oriented, allowing the divider to be inserted vertically into the slot, thus making it easier to maintain the divider's vertical position. The inclusion of a fixing component ensures the divider is more stably fixed to the housing, preventing positional shifts during transport.

[0016] Preferably, the body includes a cover plate and an opening communicating with the receiving cavity, the opening being used to insert the loose packing material, and the cover plate being detachably installed over the opening;

[0017] And / or, the edge of the cover plate is provided with a first hand grip, and the edge of the housing is provided with a second hand grip that matches the shape of the first hand grip.

[0018] In this design, by making the cover plate a detachable structure, operators can more easily open or close the opening, and more conveniently add or remove the loose packing material into the cavity, thus improving testing efficiency. At the same time, the detachable cover plate structure also facilitates cleaning and maintenance of the interior of the housing, extending the service life of the vibration testing device.

[0019] By providing a first hand grip and a second hand grip on the edge of the cover and the edge of the housing respectively, the operator can operate the cover by holding the hand grips when opening or closing it, making it easier to open or close the cover. In addition, the matching shape of the first and second hand grips plays a certain positioning role, allowing the cover to fit more accurately onto the housing, thus improving the accuracy of cover installation.

[0020] Preferably, at least one side of the housing is provided with a scale for measuring the height of the random packing, the scale extending in a vertical direction;

[0021] And / or, the diameter of the housing is 400-1000 mm.

[0022] In this design, a scale extending vertically is installed on the side of the housing, making it easier for operators to obtain the vertical height changes of the loose packing material. This more accurately reflects the repacking status of the loose packing material, making the measurement more convenient and precise, avoiding the need for additional measuring tools, and improving testing efficiency and measurement accuracy.

[0023] By setting the diameter range of the housing to 400-1000mm, the housing diameter size in actual applications can be better simulated.

[0024] Preferably, the housing is cylindrical, and in use, the axial direction of the housing is consistent with the horizontal direction;

[0025] The partition is circular and extends vertically to divide the receiving cavity into at least two sub-cavities in the axial direction of the housing.

[0026] In this design, by setting the shell to a cylindrical shape, with its axial direction aligned with the horizontal direction during use, this aligns with the placement orientation of packed towers used for loading random packing material in actual use. This better simulates the repacking of packing material in real-world applications, further improving test accuracy. The partition is set as a circle matching the cylindrical shape and extends vertically, thus dividing the accommodating cavity into at least two sub-cavities in the axial direction of the shell. Each sub-cavity is cylindrical, similar to an actual packed tower, further enhancing the accuracy of vibration testing.

[0027] Preferably, the body further includes a base, and the shape of the receiving cavity is similar to the inner cavity shape of the container for transporting the bulk packing. The base facilitates fixing the vibration testing device in one direction, so that the orientation of the receiving cavity is consistent with the orientation of the inner cavity of the container for transporting the bulk packing.

[0028] In this solution, by setting the shape of the receiving cavity to be similar to the inner cavity shape of the container for transporting loose packing, and setting the base to facilitate fixing the vibration testing device in one direction, the orientation of the receiving cavity is consistent with the orientation of the inner cavity of the container for transporting loose packing during transportation. This allows for a more accurate simulation of the placement direction of the inner cavity of the container for transporting loose packing in actual transportation scenarios, and better simulation of the re-accumulation of packing in actual use, further improving the accuracy of the test.

[0029] Preferably, the vibration testing device further includes a vibration table, and the main body is disposed on the vibration table.

[0030] In this design, the device can be placed on a vibration table during vibration testing. The vibration table simulates the vibration conditions during actual transportation, thus enabling the simulation of vibrations during transport. The vibration table can simulate various vibration conditions, thereby broadening the application range of the vibration testing device.

[0031] The positive and progressive effects of this utility model are as follows:

[0032] The vibration testing device is used to simulate the volume change of packing material during transportation. The vibration testing device includes a main body, which includes a shell and a receiving cavity inside the shell for accommodating the packing material. When vibration testing is performed, the main body can easily observe and measure the volume change of the loosely packed packing material in the receiving cavity. Operators can know the volume change of the loosely packed packing material before and after vibration, and thus obtain the void situation caused by the re-accumulation of the loosely packed packing material during transportation. This allows for timely detection of re-accumulation problems of the loosely packed packing material before or during transportation, facilitating rapid handling and improving the performance of the loosely packed packing material after transportation.

[0064] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0065] Example 1

[0066] like Figures 1a-1c As shown, the packed tower 10 is typically transported horizontally to the target customer's location and then erected for use. This causes vibration in the loose packing 20 during horizontal transport, resulting in the re-accumulation of the loose packing 20 and the creation of voids 30. After the packed tower 10 is erected at the usage site, as... Figure 1c The first region 31 shown is completely free of the loose packing 20, as... Figure 1c There are pores between the random packing 20 in the second region 32 shown. These pores 30 can cause gas-liquid short circuits, but the size of these pores 30 is difficult to measure, and it is difficult for operators to know the specific situation of the pores 30.

[0067] like Figure 2 As shown, this embodiment provides a vibration testing device 100, which is used to simulate and test the volume change of the loose packing material during transportation. The vibration testing device 100 includes a body 200, which includes a housing 220 and a receiving cavity 230 disposed in the housing 220 for accommodating the loose packing material. The body 200 can facilitate the observation and measurement of the volume change of the loose packing material in the receiving cavity 230.

[0068] When vibration testing is performed, the main body 200 can easily observe and measure the volume change of the loose packing in the accommodating cavity 230. Operators can know the volume change of the loose packing before and after vibration, and thus obtain the void situation caused by the re-accumulation of the loose packing during transportation. This allows for timely detection of the re-accumulation problem of the loose packing before or during transportation, facilitating rapid handling and improving the performance of the loose packing after transportation.

[0069] In this embodiment, at least a portion of the housing 220 is made of transparent material. The height of the internal random packing can be observed through the transparent material. The transparent material is provided with a scale to display the change in the height of the random packing, so that the operator can observe the change in the height of the random packing inside the housing 220 through the transparent part of the housing 220, and know the specific height of the random packing more accurately through the scale provided on the transparent material.

[0070] In this embodiment, the entire housing 220 is made of transparent material, specifically plexiglass. In other embodiments, transparent material may be used only in parts of the housing 220, such as the top area when the housing 220 is in transport mode. This is sufficient to ensure that operators can see the volume changes of the internal bulk packing. Those skilled in the art can also select appropriate locations and ranges for the transparent material based on actual needs.

[0071] In other embodiments, the housing 220 may be configured as a detachable structure, thereby allowing the operator to open the housing 220 to observe the volume change of the random packing inside the receiving cavity 230. Alternatively, the volume change of the random packing inside the receiving cavity 230 may be obtained by setting a resistor or other means. Those skilled in the art can choose an appropriate method to observe and measure the volume change of the random packing inside the receiving cavity 230 according to the actual situation.

[0072] The vibration testing device 100 also includes a separator 300 connected to the main body 200. The separator 300 divides the receiving cavity 230 into at least two sub-cavities 231 so that the sub-cavities 231 can be used to accommodate different types of random packing materials. The vibration testing device 100 further divides the receiving cavity 230 into multiple sub-cavities 231 through the separator 300. Different sub-cavities 231 accommodate different types of random packing materials, allowing vibration testing of different types of random packing materials to be performed simultaneously, improving testing efficiency and reducing repetitive testing operations.

[0073] In this embodiment, there is one partition 300, which divides the receiving cavity 230 into two sub-cavities 231. In other embodiments, there may be two or more partitions, and the number of sub-cavities 231 may be multiple. Those skilled in the art can choose according to the actual situation.

[0074] The housing 220 is provided with a slot 240 that matches the shape of the partition 300. The partition 300 can be inserted into the slot 240, thereby dividing the receiving cavity 230 into at least two sub-cavities 231 in the horizontal direction to accommodate different types of bulk packings. By inserting the partition 300 into the slot 240 on the housing 220 that matches its shape, the receiving cavity 230 can be easily divided into at least two sub-cavities 231 in the horizontal direction to accommodate different types of bulk packings, making the installation and removal of the partition 300 more convenient. By setting the slot 240 and the partition 300 to match their shapes, the insertion position of the partition 300 can also be made more accurate, facilitating the positioning of the partition 300.

[0075] The vibration testing device 100 can simulate the volume change of the packing material before and after transportation. The vibration testing device 100 has two placement states. Before transportation, the vibration testing device 100 is placed vertically to fill the loose packing material, i.e., the assembled state. During transportation, the vibration testing device 100 is placed horizontally to simulate the placement of the packed tower, i.e., the usage state.

[0076] In the assembled state, the slot 240 is located on the side of the housing 220 and is arranged in a horizontal direction. The operator fills the receiving cavity 230 with a kind of loose packing material. After the loose packing material is filled, the operator inserts the separator 300 horizontally into the slot 240 and then fills the second kind of loose packing material, which facilitates the operation of the operator.

[0077] In use, the slot 240 is located at the upper end of the housing 220 and is arranged in a vertical direction so that the divider 300 is inserted into the slot 240 in a vertical direction, thereby making it easier for the divider 300 to remain in a vertical state.

[0078] The main body 200 includes a cover plate 210 and an opening communicating with the receiving cavity 230. The opening is used to insert loose packing material, and the cover plate 210 is detachably fitted over the opening. By making the cover plate 210 a detachable structure, operators can more easily open or close the opening, and it is easier to add or remove loose packing material into the receiving cavity 230, thus improving testing efficiency. At the same time, the detachable cover plate 210 structure also facilitates the cleaning and maintenance of the interior of the housing 220, extending the service life of the vibration testing device 100.

[0079] In this embodiment, a cover plate 210 is provided only at one end of the housing 220. Combined with a detachable separator 300, operators only need to open one cover plate 210 to load various types of random packing materials, eliminating the need for multiple cover plates 210. This results in a simpler structure and reduced usage and maintenance costs. In other embodiments, cover plates 210 can be provided at both ends of the housing 220. Those skilled in the art can select the appropriate number and location of cover plates 210 based on actual conditions.

[0080] The edge of the cover plate 210 is provided with a first handle portion 211, and the edge of the housing 220 is provided with a second handle portion 221 that matches the shape of the first handle portion 211. By providing the first handle portion 211 and the second handle portion 221 on the edges of the cover plate 210 and the housing 220 respectively, the operator can operate the cover plate 210 by holding the handle portion when opening or closing it, making it easier to open or close the cover plate 210. In addition, the matching first handle portion 211 and second handle portion 221 play a certain positioning role, allowing the cover plate 210 to fit more accurately onto the housing 220, improving the accuracy of the cover plate 210 installation.

[0081] At least one side of the housing 220 is provided with a scale 250 for measuring the height of the loose packing material, and the scale 250 extends vertically. By providing a scale 250 extending vertically on the side of the housing 220, it is easier for operators to obtain the height change of the loose packing material in the vertical direction, more accurately reflect the repacking situation of the loose packing material, and make the measurement more convenient and accurate, avoiding the need for additional measuring tools and improving testing efficiency and measurement accuracy.

[0082] The diameter of housing 220 is 400-1000mm. By setting the diameter range of housing 220 to 400-1000mm, the diameter size of housing 220 in actual applications can be better simulated.

[0083] The housing 220 is cylindrical, and in use, its axial direction is aligned with the horizontal direction. The partition 300 is circular and extends vertically to divide the receiving cavity 230 into at least two sub-cavities 231 in the axial direction of the housing 220. By setting the housing 220 to a cylindrical shape and ensuring its axial direction is aligned with the horizontal direction in use, this aligns with the placement orientation of packed towers used for loading random packing in actual use, better simulating the repacking of packing in real-world applications and further improving test accuracy. The partition 300, being circular to match the cylindrical shape and extending vertically, divides the receiving cavity 230 into at least two sub-cavities 231 in the axial direction of the housing 220, making each sub-cavity 231 cylindrical, similar to an actual packed tower, further improving the accuracy of vibration testing. In this embodiment, the housing 220 is set to a cylindrical shape consistent with commonly used packed towers. In other embodiments, the housing 220 may also be set to other shapes deemed suitable by those skilled in the art.

[0084] The main body 200 also includes a base 400. The shape of the receiving cavity 230 is similar to the inner cavity shape of the container transporting the bulk packing. Specifically, the shape of the receiving cavity 230 is set to be similar to the inner cavity shape of the container transporting the bulk packing. The receiving cavity 230 can be a scaled-down version of the actual container transporting the bulk packing. For example, if the inner cavity shape of the container transporting the bulk packing is cylindrical, then the receiving cavity 230 will also be set as a scaled-down cylinder. The base 400 facilitates fixing the vibration testing device 100 in one direction, so that the orientation of the receiving cavity 230 is consistent with the orientation of the inner cavity of the container transporting the bulk packing during transportation. During vibration testing, the orientation of the receiving cavity 230 can be maintained consistent with the orientation of the inner cavity of the container transporting the bulk packing through the fixing of the base 400.

[0085] In this embodiment, the vibration testing device 100 is configured as a cylindrical structure, and the cylindrical structure is fixed in a horizontal direction by the base 400, that is, the axis of the cylindrical structure is parallel to the horizontal direction. This allows for a more accurate simulation of the situation of loose packing in the container under actual transportation scenarios, and better simulation of the re-accumulation of packing in actual use, thereby further improving the accuracy of the test.

[0086] In this embodiment, the base 400 includes a fixing surface 410, which is parallel to the axial direction of the housing 220. The outer peripheral surface of the housing 220 is connected to the fixing surface 410. By connecting the outer peripheral surface of the housing 220 to the fixing surface 410, the housing 220 can be placed more stably, preventing it from flipping during vibration and affecting the vibration test results. The parallelism between the fixing surface 410 and the axial direction of the housing 220 further facilitates maintaining the housing 220 in the same orientation as the actual packed tower. In other embodiments, those skilled in the art can also use other suitable methods to make the base 400 convenient for fixing the vibration testing device 100 in one direction, so that the orientation of the receiving cavity 230 is consistent with the orientation of the inner cavity of the container for the loose packing during transportation.

[0087] The vibration testing device 100 also includes a vibration table, on which the main body 200 is mounted. During vibration testing, the main body 200 can be placed on the vibration table to simulate the vibration conditions during actual transportation, thus enabling the simulation of vibration during transport. The vibration table can simulate various vibration conditions, thereby broadening the application range of the vibration testing device 100.

[0090] like Figure 3 and Figure 4 As shown, in this embodiment, the edge of the separator 300 is provided with a handle 310, which is located on the outside of the housing 220, making it easier for the operator to hold the handle 310 for operation and making it easier to install and disassemble the separator 300.

[0093] like Figure 5 and Figure 6As shown, in this embodiment, the housing 220 further includes a fixing member 260, which can fix the relative position of the partition 300 and the housing 220. By providing the fixing member 260, the partition 300 can be more stably fixed to the housing 220, avoiding positional displacement of the partition 300 during transportation. Specifically, the fixing member 260 includes a connecting portion 261 and a bolt 262 provided on the side of the housing 220. The connecting portion 261 and the partition 300 are respectively provided with mounting holes, and the bolt 262 passes through the mounting holes to fix the partition 300 to the housing 220. In other embodiments, those skilled in the art can also choose other suitable structures for the fixing member 260.
