Description

Technical Field

[0001] This application relates to the technical field of water absorption rate testing, and in particular to a device for testing the water absorption rate of foam ceramics. Background Technology

[0002] Foam ceramics, as a new type of ceramic material with a porous structure, are widely used in filtration, heat preservation, catalytic carrier and other fields. Its water absorption rate is an important indicator for measuring the porosity, pore size distribution and performance of the material. Too high a water absorption rate will lead to a decrease in material strength and a shortened service life, while too low a water absorption rate will not meet the functional requirements of filtration, adsorption and other functions. Therefore, accurate detection of the water absorption rate of foam ceramics is crucial for product quality control. Currently, the water absorption rate of foam ceramics is mainly tested using the conventional method of soaking-dehydration-weighing. This involves first weighing the dried foam ceramic to obtain its dry weight, then soaking it in water until saturated, removing excess surface moisture, and finally weighing it again to obtain the dehydrated weight. The water absorption rate is then calculated as (dehydrated weight - dry weight) / dry weight × 100%. However, existing testing equipment often uses natural air drying or manual wiping for dehydration. Natural air drying is easily affected by ambient temperature and humidity, leading to unstable evaporation rates. Manual wiping can easily damage the ceramic surface due to uneven wiping force. Furthermore, because foam ceramics are porous, manual wiping cannot remove excess moisture from the internal pores, resulting in incomplete dehydration. This manual intervention leads to low controllability and low accuracy. Additionally, after dehydration, the foam ceramic needs to be transferred to an electronic scale for weighing, which can cause water dripping or secondary absorption, resulting in distorted weight data, insufficient testing accuracy, and low testing efficiency. Utility Model Content

[0003] To address the issues that most dehydration methods in testing equipment involve natural air drying or manual wiping, which result in low controllability and low testing accuracy due to human intervention, and the need to transfer the foam ceramic to an electronic scale for weighing after dehydration, which can easily lead to distorted weight data, insufficient testing accuracy, and low testing efficiency, this application provides a foam ceramic water absorption rate testing device.

[0004] This application provides a device for testing the water absorption rate of foamed ceramics, which adopts the following technical solution: A device for testing the water absorption rate of foamed ceramics, including A soaking tube, wherein a shelf for placing foam ceramics is installed inside the soaking tube; A dehydration cylinder is disposed on one side of the soaking cylinder. The dehydration cylinder includes an outer cylinder, a filter cylinder, a drive unit, and a dynamic weighing unit. Multiple support columns are provided at the bottom of the outer cylinder. The filter cylinder is rotatably installed inside the outer cylinder. A drain pipe is installed at the bottom of the outer cylinder. The drive unit is disposed at the bottom of the outer cylinder and drives the filter cylinder to rotate. A base plate is detachably installed at the bottom of the filter cylinder. Multiple dynamic weighing units are disposed on the base plate. A support frame for equidistantly placing water-absorbed foam ceramics is installed at the end of each dynamic weighing unit away from the base plate. A control component is provided, which is electrically connected to the drive unit and the dynamic weighing unit, respectively.

[0005] By adopting the above technical solution, the soaking tank provides a soaking space for the foam ceramics, and the shelf can stably separate and place the foam ceramics to avoid uneven water absorption caused by stacking, ensuring that the foam ceramics can fully contact water to reach a saturated water absorption state; the dehydration tank is set adjacent to the soaking tank, shortening the transfer path of the foam ceramics, and the outer tank is stably supported by the support column. The filter tank rotates under the drive unit to generate centrifugal force, which can efficiently remove excess water inside the foam ceramics, replacing traditional manual wiping or natural drying, and avoiding human damage and environmental interference; the dynamic weighing unit is integrated in the filter tank, and the foam ceramics can be weighed directly after dehydration without additional transfer, reducing the risk of weight data distortion; the control component realizes automated control of the drive unit speed, rotation time and dynamic weighing unit data acquisition, which greatly improves the detection efficiency and accuracy compared with traditional manual operation, and ensures the consistency and reliability of the detection results.

[0006] Optionally, a gap is provided between the outer cylinder and the filter cylinder, multiple guide wheels are installed at the bottom of the filter cylinder, a guide groove is opened at the bottom of the outer cylinder, the guide wheels are configured to cooperate with the guide groove, and the guide wheels slide along the guide groove.

[0007] By adopting the above technical solution, the gap between the outer cylinder and the filter cylinder provides sufficient space for the rotation of the filter cylinder, and at the same time facilitates the water thrown out by the filter cylinder to collect in the gap and flow to the drain pipe; the matching structure of the guide wheel and the guide groove provides precise guidance for the rotation of the filter cylinder, limits the radial displacement of the filter cylinder, avoids the filter cylinder from shaking or deviating during high-speed rotation, ensures that the filter cylinder always rotates stably along the preset trajectory, and ensures the stability of the centrifugal dehydration process.

[0008] Optionally, the drive unit includes a drive component, a first rotating shaft, and a second rotating shaft. A base plate is installed at the bottom of the outer cylinder. The drive component is disposed on one side of the base plate. The output end of the drive component is driven and connected to the first rotating shaft. A first bevel gear is coaxially sleeved at the end of the first rotating shaft. A second bevel gear is meshed with the first bevel gear. The second rotating shaft is disposed along the central axis of the outer cylinder. The second bevel gear is coaxially sleeved on the second rotating shaft. The second rotating shaft passes through the outer cylinder and the gap in sequence and is connected to the water filter cylinder.

[0009] By adopting the above technical solution, the substrate provides a stable mounting base for the drive component. The drive component transmits power to the first bevel gear through the first rotating shaft. Utilizing the meshing transmission characteristics of the bevel gear, the power direction is vertically converted, transforming the horizontal driving force into a vertical driving force along the central axis of the outer cylinder, precisely matching the rotational requirements of the filter cylinder. The second rotating shaft is set along the central axis of the outer cylinder, ensuring uniform force on the filter cylinder and avoiding rotational imbalance caused by transmission eccentricity. The entire transmission structure is compact, with high power transmission efficiency, and can stably provide rotational power to the filter cylinder, ensuring the stability of the centrifugal dewatering effect.

[0010] Optionally, a seal is installed at the connection between the second rotating shaft and the outer cylinder.

[0011] By adopting the above technical solution, the seal can effectively block the gap between the second rotating shaft and the outer cylinder, prevent the dewatering water collected in the outer cylinder from leaking out from the connection, avoid water contact with the drive unit below causing equipment failure, and at the same time prevent external dust and impurities from entering the inner cylinder to contaminate the dewatering or affect the rotation of the filter cylinder.

[0012] Optionally, a connecting plate is provided inside the water filter cylinder, one end of the dynamic weighing unit is detachably connected to the base plate, and the other end is detachably connected to the connecting plate, and the connecting plate is horizontally arranged, and the support frame is installed on the connecting plate.

[0013] By adopting the above technical solution, the horizontally set connecting plate can connect multiple dynamic weighing units into a whole, ensuring that all dynamic weighing units are subjected to balanced forces and avoiding inaccurate weighing data due to force deviation of a single weighing unit; the horizontal state of the connecting plate can ensure that the support frame is always in a horizontal position, so that the foam ceramic placed on the support frame is subjected to uniform forces and will not shift due to tilting, thereby ensuring that the dehydration effect of all parts of the foam ceramic is consistent during centrifugal dehydration; at the same time, the detachable connection between the dynamic weighing unit and the base plate and connecting plate facilitates the later inspection, replacement or calibration of the dynamic weighing unit, reducing the difficulty and cost of equipment maintenance.

[0014] Optionally, the support frame is made of a flexible, non-absorbent polymer material that resists centrifugal deformation, and multiple storage slots for placing the foam ceramics are equidistantly provided on the side of the support frame away from the connecting plate.

[0015] By adopting the above technical solutions, the flexible material can prevent the support frame from scratching or squeezing the surface of the foam ceramic when it comes into contact with it, thus protecting the structural integrity of the foam ceramic; the non-absorbent property can prevent the support frame from absorbing moisture, thus avoiding moisture residue affecting the weight test results of the foam ceramic; the anti-centrifugal deformation performance ensures that the support frame will not deform under the centrifugal force generated by the high-speed rotation of the filter cylinder, ensuring that the foam ceramic is always in a stable placement state; the equidistantly spaced storage slots can individually separate and position the foam ceramic, avoiding collisions between multiple foam ceramics during centrifugation, while ensuring that the dehydration centrifugal force of each foam ceramic is consistent, further improving the accuracy and consistency of the test results.

[0016] Optionally, a solenoid valve is provided on the drain pipe, and the solenoid valve is electrically connected to the control component.

[0017] By adopting the above technical solution, the control component can automatically control the opening and closing of the drain pipe through the solenoid valve, eliminating the need for manual switching and reducing manual intervention. During the dehydration process, the control component can simultaneously open the solenoid valve to ensure that the dehydrated water collected in the outer cylinder is discharged through the drain pipe in a timely manner, preventing excessive water accumulation in the outer cylinder from flooding the filter cylinder and affecting the dehydration effect. After the dehydration is completed, the control component can control the solenoid valve to close, preventing external impurities from entering the outer cylinder through the drain pipe.

[0018] Optionally, the filter cylinder has multiple filter holes arranged on its cylinder wall, and a cover is installed on the top of the outer cylinder, with a set distance between the inner wall of the cover and the filter cylinder.

[0019] By adopting the above technical solution, the filter holes on the filter cylinder wall can quickly discharge the water thrown out by centrifugal force into the gap between the outer cylinder and the filter cylinder, ensuring that the water leaves the foam ceramic in time and improving the dewatering efficiency. At the same time, the filter holes can prevent the foam ceramic or its debris from being discharged with the water, avoiding the loss of foam ceramic or clogging of the drain pipe. The cover on the top of the outer cylinder can prevent water from splashing from the top of the outer cylinder when the filter cylinder rotates at high speed, keeping the surrounding environment of the equipment clean. The set distance between the inner wall of the cover and the filter cylinder can provide sufficient space for the rotation of the filter cylinder, avoiding friction and collision between the two, and effectively blocking water splashing.

[0020] Optionally, a transfer rack for transferring foam ceramics is provided between the soaking tank and the dehydration tank.

[0021] By adopting the above technical solution, the transfer rack provides a channel for transferring foam ceramics from the soaking tank to the dehydration tank, shortening the transfer path and reducing the risk of water dripping or secondary water absorption; the transfer rack can provide temporary support for the foam ceramics, avoiding hand contamination or ceramic damage caused by improper force during manual transfer.

[0022] Optionally, a water level sensor is provided on the inner wall of the soaking tank, and the water level sensor is electrically connected to the control component.

[0023] By adopting the above technical solution, the water level sensor can monitor the water level in the soaking tank in real time and transmit the water level data to the control component. When the water level is not high enough to completely submerge the foam ceramic, the control component can issue a prompt signal to remind the operator to add water in time to avoid the foam ceramic from becoming unsaturated due to insufficient water level, which would affect the accuracy of the test results. When the water level reaches the preset standard, the control component can record the soaking start time to provide data support for subsequent precise control of the soaking time.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The foam ceramic is fully saturated with water by soaking in the soaking tank, and then the excess water is removed by centrifugation in the dehydration tank. The weight change is monitored in real time by a dynamic weighing unit. Finally, the control component automatically calculates the water absorption rate, realizing automated and accurate detection of the water absorption rate of foam ceramic. This reduces manual operation steps, speeds up the detection process, avoids the problems of natural air drying being affected by the environment, manual wiping damaging the sample, and incomplete dehydration, and also eliminates weight errors during the transfer process, making the detection data more accurate and reliable. 2. The drive unit drives the first rotating shaft to rotate through the drive component. The first bevel gear and the second bevel gear, which are connected by meshing transmission, convert the rotational motion of the first rotating shaft into the rotational motion of the second rotating shaft. This, in turn, drives the filter cylinder to rotate stably around the central axis of the outer cylinder. The centrifugal force is used to remove excess water from the surface and internal pores of the foam ceramic, providing precise and controllable power for the dehydration process of foam ceramic water absorption rate detection.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a device for testing the water absorption rate of foamed ceramics, referring to... Figures 1-3The foam ceramic water absorption rate testing equipment includes an immersion tank, a dehydration tank 1, and a control component. The immersion tank contains a shelf for placing the foam ceramics. The dehydration tank 1 is located on one side of the immersion tank and includes an outer tank 11, a filter tank 12, a drive unit 17, and a dynamic weighing unit 16. Multiple support columns 2 are located at the bottom of the outer tank 11. The filter tank 12 is rotatably installed inside the outer tank 11, and a drain pipe 3 is installed at the bottom of the outer tank 11. The drive unit 17 is located at the bottom of the outer tank 11 and drives the filter tank 12 to rotate. A base plate 13 is detachably installed at the bottom of the filter tank 12. Multiple dynamic weighing units 16 are mounted on the base plate 13. A support frame 14 for equidistantly placing the water-absorbed foam ceramics is installed at the end of each dynamic weighing unit 16 away from the base plate 13. The control component is electrically connected to the drive unit 17 and the dynamic weighing unit 16.

[0032] The soaking tank in this device serves as the soaking container for the foam ceramics, providing ample space for the foam ceramics to come into contact with water, allowing them to be soaked until saturated. The rack inside the soaking tank is used to stably hold the dried foam ceramics, ensuring that they do not move around during the soaking process and guaranteeing that each part absorbs water evenly.

[0033] The outer cylinder 11 in the dewatering cylinder 1 provides installation space and support for the rotation of the filter cylinder 12. The support column 2 at the bottom of the outer cylinder 11 plays a role in stabilizing and supporting the outer cylinder 11, so that the outer cylinder 11 remains stable during the rotation of the filter cylinder 12. The drain pipe 3 is used to drain the water that is separated from the foam ceramic during the dewatering process, so as to avoid water accumulation in the cylinder and affect the dewatering effect.

[0034] The filter cylinder 12 is used to hold the foam ceramic after it has absorbed water. Driven by the drive unit 17, it rotates and uses centrifugal force to shake off excess water from the surface and internal pores of the foam ceramic. Compared with natural air drying and manual wiping, the dehydration is more thorough, stable, and efficient. At the same time, the centrifugal dehydration method avoids the damage to the foam ceramic that may be caused by manual wiping, thus ensuring the integrity of the sample.

[0035] The drive unit 17 provides power for the rotation of the filter cylinder 12, driving the filter cylinder 12 to rotate according to a set speed and time. The drive unit 17 receives instructions from the control component and adjusts its own operating state to control the rotation of the filter cylinder 12. Through the drive unit 17 and the control component, the dewatering requirements of foam ceramics of different specifications can be adapted, ensuring the consistency and controllability of the dewatering effect and improving the standardization of the dewatering process.

[0036] The dynamic weighing unit 16 is used to monitor the weight change of the foam ceramic placed on the support frame 14 in real time during the dehydration process. The dynamic weighing unit 16 can also transmit the weight data to the control component in real time, providing a basis for determining whether dehydration is complete and avoiding errors caused by manual judgment. At the same time, the dynamic weighing function eliminates the step of transferring the ceramic for weighing after dehydration, reducing weight data distortion caused by water dripping or secondary water absorption, and improving detection accuracy. In this application, the dynamic weighing unit 16 is prior art and will not be described in detail here.

[0037] The base plate 13 can fix multiple dynamic weighing units 16 inside the bottom of the filter cylinder 12, and at the same time facilitates the overall assembly and disassembly of the dynamic weighing units 16 and the support frame 14, which facilitates the maintenance and cleaning of the equipment, as well as the replacement of corresponding parts according to different testing requirements. The support frame 14 is used to place the foam ceramics after water absorption at equal intervals, so that the foam ceramics remain stable during the dehydration process, avoid mutual collision, and ensure that each foam ceramic is evenly stressed for dehydration, resulting in consistent dehydration effect and improving the repeatability of testing the same batch of samples.

[0038] The control component can receive weight data transmitted by the dynamic weighing unit 16 and control the operation of the drive unit 17 according to a preset program (such as starting, stopping, and adjusting the speed). Simultaneously, it can automatically calculate the water absorption rate and record relevant data, achieving automated control of the entire testing process, reducing manual intervention, and improving testing efficiency. Through the coordinated control of the drive unit 17 and the dynamic weighing unit 16, precise coordination between the dehydration and weighing stages is ensured, making the calculation of the water absorption rate more accurate.

[0039] The foam ceramic water absorption rate testing equipment uses an immersion tube to fully absorb water to saturation, and then uses a dehydration tube 1 to centrifuge and remove excess water. The dynamic weighing unit 16 monitors the weight change in real time, and finally the control component automatically calculates the water absorption rate, realizing the automated and accurate detection of the foam ceramic water absorption rate.

[0040] Specifically, this equipment integrates centrifugal dehydration and dynamic weighing functions, avoiding the problems of natural air drying being affected by the environment, manual wiping damaging samples, and incomplete dehydration. It also eliminates weight errors during the transfer process, making the test data more accurate and reliable. Simultaneously, the automated dehydration, weighing, and calculation processes reduce manual operation steps, accelerate the testing speed, meet the testing needs of batch samples, and improve work efficiency. Precise control of each step through control components standardizes parameters such as dehydration time and rotation speed, ensuring consistent testing conditions for different batches of samples, improving the controllability of the testing process and the repeatability of the results.

[0041] A water level sensor is installed on the inner wall of the soaking tank. The sensor is electrically connected to the control component and is used to detect the water level in the tank in real time. It transmits the collected water level signal to the control component in real time, ensuring that the foam ceramic is completely covered by water and fully absorbs water to saturation. This provides a prerequisite for accurate subsequent water absorption rate testing. Simultaneously, through linkage with the control component, it can issue a warning or automatically replenish water when the water level falls below a preset value, reducing manual intervention and improving the stability of the soaking process.

[0042] A transfer rack for transferring foam ceramics is provided between the soaking tank and the dehydration tank 1. The transfer rack is used to support the foam ceramics that have completed saturation water absorption, realizing the transfer of the sample from the soaking stage to the dehydration stage. Its structure needs to be adapted to the size and shape of the foam ceramics. At the same time, it can be manually operated or in conjunction with automated components to smoothly transfer the soaked foam ceramics from the shelf of the soaking tank to the support frame 14 of the filter tank 12 of the dehydration tank 1.

[0043] refer to Figure 3 A gap is provided between the outer cylinder 11 and the filter cylinder 12. Multiple guide wheels 122 are installed at the bottom of the filter cylinder 12. A guide groove 111 is opened at the bottom of the outer cylinder 11. The guide wheels 122 are matched with the guide groove 111 and slide along the guide groove 111. The gap between the outer cylinder 11 and the filter cylinder 12 can provide sufficient range of motion for the rotation of the filter cylinder 12 driven by the drive unit 17, and avoid friction and collision between the filter cylinder 12 and the inner wall of the outer cylinder 11 when the filter cylinder 12 rotates. In addition, the gap can catch the excess water thrown out from the pores of the filter cylinder 12, so that the water can flow quickly along the gap to the drain pipe 3 at the bottom of the outer cylinder 11, and prevent the water from accumulating on the outer wall of the filter cylinder 12 and then adhering to the foam ceramic.

[0044] The guide wheel 122 is directly connected to the filter cylinder 12 and rotates synchronously with it, providing vertical support and horizontal restraint for the filter cylinder 12. The guide groove 111 serves as a constraint structure for the motion trajectory of the guide wheel 122. The shape of the guide groove 111 matches that of the guide wheel 122, limiting the sliding path of the guide wheel 122 and ensuring that the guide wheel 122 always moves along a fixed trajectory, that is, the guide wheel 122 slides along the guide groove 111 when the filter cylinder 12 rotates. The guide wheel 122 replaces the traditional rigid support structure, converting the sliding friction of the filter cylinder 12 during rotation into rolling friction, significantly reducing frictional resistance, reducing the power loss of the drive unit 17, and enabling the filter cylinder 12 to reach the preset speed more smoothly and efficiently, ensuring the consistency of the centrifugal dewatering effect. refer to Figures 1-3The drive unit 17 includes a drive component 171, a first rotating shaft 172, and a second rotating shaft 173. A base plate 174 is mounted on the bottom of the outer cylinder 11. The drive component 171 is disposed on one side of the base plate 174. The output end of the drive component 171 is driven and connected to the first rotating shaft 172. A first bevel gear 175 is coaxially sleeved at the end of the first rotating shaft 172. The first bevel gear 175 is meshed with a second bevel gear 176. The second rotating shaft 173 is disposed along the central axis of the outer cylinder 11. The second bevel gear 176 is coaxially sleeved on the second rotating shaft 173. The second rotating shaft 173 passes through the outer cylinder 11 and the gap in sequence and is connected to the water filter cylinder 12.

[0045] The drive unit 171 converts electrical energy and other forms of energy into mechanical energy, operating according to preset instructions from the control components to provide the initial power for the rotation of the first rotating shaft 172. Common drive units 171 can be stepper motors or servo motors, capable of precisely responding to control signals and adapting to the rotational speed requirements of the filter cartridge 12 during the dehydration of different specifications of foam ceramics. Operators can flexibly control the centrifugal speed of the filter cartridge 12 by adjusting the rotational speed of the drive unit 171. For example, for foam ceramics with high porosity, the rotational speed can be appropriately increased to thoroughly remove excess water from the internal pores; for samples with more fragile structures, the rotational speed can be reduced to avoid sample damage and improve the controllability of the dehydration process. The first rotating shaft 172 directly transmits the rotational power output by the drive unit 171 to the first bevel gear 175. The axial direction of the first rotating shaft 172 is consistent with the output direction of the drive unit 171, and its length is adapted to the spatial layout between the substrate 174 and the outer cylinder 11. The first bevel gear 175 can receive the rotational power transmitted by the first rotating shaft 172 and change the power transmission direction by utilizing the meshing characteristics of the bevel gear teeth (converting the horizontal power of the first rotating shaft 172 into the vertical power of the second rotating shaft 173), and then transmit the power to the second bevel gear 176. This achieves the conversion of the power transmission direction and is adapted to the structural layout where the drive unit 171 is horizontally mounted on one side of the substrate 174 and the second rotating shaft 173 is vertically arranged along the central axis of the outer cylinder 11, solving the problem of power transmission direction conflict caused by equipment space limitations. At the same time, the bevel gear meshing transmission has the characteristics of high transmission efficiency and strong load-bearing capacity, which can ensure that there is no significant power loss during the turning process, ensure the stability of the rotation speed of the filter cylinder 12, and avoid uneven dehydration caused by power fluctuations. The second bevel gear 176 receives the vertical rotational power transmitted by the first bevel gear 175 and transmits it to the second rotating shaft 173, enabling the second rotating shaft 173 to obtain a speed and direction matching the meshing transmission, thereby driving the filter cylinder 12 to rotate synchronously. The number of teeth and module of the second bevel gear 176 can be set in combination with the first bevel gear 175 according to the dewatering speed requirements to achieve fine-tuning of the speed. The second rotating shaft 173 directly transmits the rotational power transmitted by the second bevel gear 176 to the filter cylinder 12, driving the filter cylinder 12 to rotate around its own axis, thereby generating centrifugal force to achieve dewatering of the foam ceramic. The length of the second rotating shaft 173 is adapted to the height of the outer cylinder 11 and the installation position of the filter cylinder 12, and its surface is treated with anti-rust to cope with the water vapor environment during the dewatering process. The base plate 174 provides a stable mounting platform for the drive unit 171, and also indirectly supports and protects components such as the first rotating shaft 172 and the first bevel gear 175. A housing 177 is provided on one end of the drive unit 171, the first rotating shaft 172, the first bevel gear 175, the second bevel gear 176, and the second rotating shaft 173. The housing 177 can effectively protect the drive unit 171, bevel gears, and other precision components from the corrosion of moisture during the dehydration process, reduce the risk of component corrosion, and extend the service life of the drive unit 17.

[0046] A seal is installed at the connection between the second rotating shaft 173 and the outer cylinder 11. The seal fills the gap between the two, forming a physical sealing barrier to prevent moisture and water vapor generated during the dehydration process from seeping into the lower part of the outer cylinder 11 through the gap at the connection. At the same time, it prevents external impurities from entering the mating part between the outer cylinder 11 and the second rotating shaft 173, ensuring that the second rotating shaft 173 can always transmit power stably and flexibly, and ensuring the continuous and stable operation of the dehydration process. A connecting plate 15 is provided inside the water filter cylinder 12. One end of the dynamic weighing unit 16 is detachably connected to the base plate 13, and the other end is detachably connected to the connecting plate 15. The connecting plate 15 is horizontally set. The support frame 14 is installed on the connecting plate 15. The connecting plate 15 provides top mounting support for the dynamic weighing unit 16 and also provides a stable mounting foundation for the support frame 14, so that the support frame 14 can be installed horizontally on the connecting plate 15. At the same time, the horizontal setting itself ensures that the dynamic weighing unit 16 is subjected to uniform force.

[0047] The detachable connection between the dynamic weighing unit 16 and the base plate 13 allows for flexible assembly and disassembly. This facilitates quick removal of the dynamic weighing unit 16 from the base plate 13 for inspection or replacement when it malfunctions, requires calibration, or needs maintenance. It also facilitates precise positioning of the dynamic weighing unit 16 during initial equipment installation or adjustment. The detachable connection between the dynamic weighing unit 16 and the connecting plate 15 allows for flexible assembly and disassembly. During installation, the position of the dynamic weighing unit 16 can be fine-tuned according to the horizontal state of the connecting plate 15, ensuring a tight connection and maintaining a horizontal position. When replacing the connecting plate 15 or the dynamic weighing unit 16, they can be quickly separated, reducing operational difficulty. In this application, the detachable connection can be a bolted connection or other detachable structures such as clips, depending on actual needs, facilitating installation and disassembly while ensuring a secure connection. The support frame 14 is used to place the foam ceramic. Through its own structure, it stably supports the foam ceramic in the filter cylinder 12, preventing the foam ceramic from shaking, tipping over or colliding with each other during the dehydration process of the filter cylinder 12. At the same time, it ensures the stable force transmission between the foam ceramic and the dynamic weighing unit 16. The support frame 14 is made of a flexible, non-absorbent polymer material with centrifugal deformation resistance. Multiple placement slots 141 for placing foam ceramics are equidistantly spaced on the side of the support frame 14 away from the connecting plate 15. The support frame 14's flexibility allows it to make flexible contact with the sample surface during foam ceramic placement and dehydration, avoiding rigid collisions. Its non-absorbent nature prevents the material itself from absorbing moisture during dehydration, avoiding extra weight interference with dynamic weighing. Its centrifugal deformation resistance ensures that the support frame 14 maintains its original structural shape and does not bend or deform when the filter cylinder 12 rotates and generates centrifugal force, thus maintaining stable support for the foam ceramics. The support frame 14 can be made of plastic sponge, adaptable to foam ceramics of different sizes. The plastic sponge combines the structural stability of plastic with the porous flexibility of sponge, providing basic support for the foam ceramics while preventing moisture absorption through its porous structure. Its flexible texture also allows it to adhere to the surface of the foam ceramics, reducing contact damage. Through the elastic deformation capability of the plastic sponge, it can automatically adjust its shape according to the sample size when placing foam ceramics of different sizes, conforming to the sample surface and providing corresponding support for samples of different specifications, eliminating the need to replace the support frame 14 with one of different sizes.

[0048] The placement trough 141 provides an independent and fixed space for the foam ceramics, limiting the position of each foam ceramic and preventing samples from colliding and stacking when the filter cylinder 12 rotates. The equidistant arrangement of the placement trough 141 ensures that each sample is evenly distributed and subjected to consistent force within the filter cylinder 12, further guaranteeing the accuracy of the dynamic weighing unit 16 in monitoring the weight of each sample. At the same time, it facilitates operators to place samples quickly and in a standardized manner, improving operational efficiency.

[0049] A solenoid valve is installed on drain pipe 3, and the solenoid valve is electrically connected to the control component. The solenoid valve can directly control the flow and blockage of water in drain pipe 3. When it is necessary to drain the water generated during the dehydration process, the valve core of the solenoid valve opens to allow the water to flow smoothly through drain pipe 3, preventing water from accumulating inside the equipment and adhering to the foam ceramic again, thus affecting the dehydration effect; when drainage is not required, the valve core closes to prevent water flow and prevent external impurities from entering the equipment through drain pipe 3. The electrical connection between the solenoid valve and the control component allows the control component to send electrical signals to the solenoid valve, precisely controlling its start-stop and operating status. The control component can automatically send open or close commands to the solenoid valve according to a preset program (such as dehydration start time and dehydration duration), achieving automated control of the drainage process. Multiple filter holes 121 are arranged on the wall of the filter cylinder 12. A cover 18 is installed on the top of the outer cylinder 11, and a set distance is provided between the inner wall of the cover 18 and the filter cylinder 12. The filter holes 121 are channels for water discharge during the dehydration process. When the filter cylinder 12 rotates and generates centrifugal force, excess water thrown off the surface and internal pores of the foam ceramic is discharged into the filter cylinder 12 through the filter holes 121, allowing the water to enter the space between the outer cylinder 11 and the filter cylinder 12. The multiple filter holes 121 can quickly discharge excess water under the action of centrifugal force, preventing water from remaining in the filter cylinder 12 and re-adhering to the foam ceramic, ensuring that the dehydration conditions of all samples in the same filter cylinder 12 are uniform, and improving the consistency of test results. The cover 18 and the outer cylinder 11 form a closed dehydration space, preventing water from splashing out of the equipment from the top of the outer cylinder 11 under centrifugal force when the filter cylinder 12 rotates for dehydration. This avoids accidental injury to operators from splashed water or dampness in the surrounding environment. Simultaneously, it blocks external dust and impurities from entering the outer cylinder 11, protecting the cleanliness of the testing environment inside the outer cylinder 11 and the filter cylinder 12. A reasonable space is reserved between the cover 18 and the filter cylinder 12 to prevent friction and collision between the filter cylinder 12 and the inner wall of the cover 18 during rotation, ensuring smooth rotation of the filter cylinder 12. This space also serves as a buffer zone after water splashing, allowing a small amount of splashed water from the filter cylinder 12 to fall back to the bottom of the outer cylinder 11, preventing water from directly impacting the cover 18 and rebounding back into the filter cylinder 12, thus affecting the dehydration effect.

[0050] The implementation principle and process of the foam ceramic water absorption rate testing device in this application are as follows: The operator weighs the foam ceramic sample to be tested, records and stores the dry weight data, and then places the dried foam ceramic sample on the shelf inside the soaking tank. The control component monitors the water level in the soaking tank through the water level sensor to ensure that the water level can completely submerge the foam ceramic. The soaking tank begins immersing the dried foam ceramic. A water level sensor sends real-time feedback to the control unit, indicating the water level is insufficient. If the water level is low, water replenishment is triggered (or the operator is prompted to add water), ensuring the sample is completely submerged throughout the soaking process. Once the preset soaking time has elapsed, the saturation water absorption phase is complete. The operator uses a transfer rack to remove the soaked saturated water-absorbing foam ceramics from the soaking cylinder rack and places them one by one into the storage slot 141 of the inner support frame 14 of the dehydration cylinder 1 and the filter cylinder 12. After placement, the cover 18 on the top of the outer cylinder 11 is closed. The cover 18 is fixed to the outer cylinder 11 by a snap or thread connection to prevent the cover 18 from shifting when the filter cylinder 12 rotates at high speed. The control component sends a start command to the drive unit 17. The drive unit 17 drives the filter cylinder 12 to rotate around the central axis through the power transmission of the drive component 171, the first rotating shaft 172, the bevel gear set, and the second rotating shaft 173. Under the set time and speed of the control component, the centrifugal force generated by the rotation throws out the excess water from the surface and internal pores of the foam ceramic. The water enters the gap between the outer cylinder 11 and the filter cylinder 12 through the filter holes 121 on the wall of the filter cylinder 12. Then, the control component controls the solenoid valve on the drain pipe 3 to open, and the water is discharged through the drain pipe 3.

[0051] After a few seconds of delay following the completion of the dehydration set time, the dynamic weighing unit 16 collects weight data and transmits it to the control component, recording and storing the weight data after dehydration. The control unit automatically calculates the water absorption rate based on the pre-stored dry weight and dehydrated weight using the formula: Water Absorption Rate = (Dehydrated Weight - Dry Weight) / Dry Weight × 100%. After calculation, the equipment automatically stores the test data, such as sample number, weight at each stage, and water absorption rate results, and supports data export or display for operator viewing.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
