Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, and in particular to a mortar pressure seepage meter. Background Technology

[0002] A mortar pressure bleeding tester is a testing device used to test the bleeding performance of mortar under specific conditions. By applying pressure, water is forced out of the mortar, thereby evaluating the mortar's rheological properties and workability. Pressure bleeding testing is an important indicator in mortar mix optimization, construction quality control, and material performance evaluation. To ensure the accuracy of test results and the safety of experimental operations, mortar pressure bleeding testers typically need to have functions such as sealing, pressurization, and drainage.

[0003] Existing mortar pressure bleeding meters mainly consist of a sample cylinder, a top cover, a pressurizing device, and a drain port. The mortar sample is placed inside the sample cylinder, and the top cover is secured by threads or a clamping mechanism to prevent sample spillage. The pressurizing device, either manually or hydraulically, pushes a rod to apply a specified pressure to the mortar, causing water to seep out. The exuded water is collected through the drain port for measurement. This type of device effectively achieves both pressurization and water collection in bleeding experiments, meeting the needs of routine experiments.

[0004] However, in actual operation, a pressure difference exists between the inside and outside of the device. When the top cover needs to be removed or the sample replaced, the high-pressure gas inside the top cover will be released instantaneously, potentially spraying out mortar, posing a certain safety hazard. This not only poses a potential risk to operators but may also affect the cleanliness of the experimental environment and the reliability of test data. Therefore, there is an urgent need to improve the existing structure to achieve safe and controllable pressure release. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mortar pressure seepage device, which aims to improve the safety hazard caused by the lack of a pressure relief structure in traditional devices, which leads to the instantaneous release of high-pressure gas inside when the top cover is removed, making it easy for mortar to be sprayed out.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mortar pressure bleeding instrument, comprising a support rod, wherein a mortar bleeding component is disposed above the support rod; The mortar bleeding component includes a material cylinder, which is positioned above a support rod. A support base is fixedly connected to the upper surface of the support rod. A valve body is fixedly connected to the inner wall of the support base. The inner wall of the support base is threadedly connected to the outer wall of the material cylinder. A top cover is threadedly connected to the outer wall of the material cylinder. A connecting block is fixedly connected to the upper surface of the top cover. A pressure gauge is fixedly connected to the inner wall of the connecting block. A connecting pipe is fixedly connected to the outer wall of the connecting pipe. An air pipe is fixedly connected to the outer wall of the connecting pipe. An exhaust component is provided on the inner wall of the top cover.

[0007] The above technical solution enables precise control and monitoring of the internal pressure of the mortar cylinder during the measurement of mortar bleeding. It can apply uniform air pressure to effectively separate the water in the mortar. At the same time, the safety of the pressurization operation is ensured by the exhaust component and pressure gauge, ensuring that the main body of mortar is intercepted, the bleeding data is accurate and reliable, the operation is simple and has high repeatability and stability.

[0008] Preferably, the exhaust assembly includes a pressure relief valve, the outer wall of which is fixedly connected to the inner wall of the top cover. A threaded rod is threadedly connected to the inner wall of the pressure relief valve, and a rubber plate is fixedly connected to the outer wall of the threaded rod. A spring is sleeved on the outer wall of the threaded rod, one end of which is fixedly connected to the inner wall of the pressure relief valve, and the other end of which is fixedly connected to the upper surface of the rubber plate. A conical rubber block is fixedly connected to one end of the threaded rod. A fixing block is fixedly connected to the inner wall of the pressure relief valve, and a sealing ring is fixedly connected to the upper surface of the fixing block. The outer wall of the conical rubber block is slidably connected to the inner wall of the sealing ring. A pressure relief pipe is fixedly connected to the outer wall of the pressure relief valve, and a filter screen is fixedly connected to the inner wall of the pressure relief valve.

[0009] Through the above technical solution, the internal pressure of the mortar bleeding test cylinder is automatically adjusted and safely released during the test. When the internal air pressure exceeds the set value, the threaded rod drives the rubber plate to compress the spring, causing the conical rubber block to slide out from the sealing ring. Excess gas is discharged through the pressure relief pipe, preventing mortar from splashing or causing operational hazards. At the same time, the filter screen blocks impurities from being discharged with the gas, ensuring smooth exhaust without affecting the measurement accuracy, thereby improving the safety and reliability of the testing process.

[0010] Preferably, a fixing ring is fixedly connected to the inner wall of the support base, and a filter screen is slidably connected to the inner wall of the support base.

[0011] The above technical solution enables effective separation and precise measurement of mortar bleeding. The fixing ring provides a stable support position for the filter screen, ensuring that it will not move or tilt during the bleeding process.

[0012] Preferably, a fixing block two is fixedly connected to the upper surface of the filter screen two, and a handle is rotatably connected to the inner wall of the fixing block two.

[0013] The above technical solution enables convenient installation and removal of filter screen two.

[0014] Preferably, a connecting plate is fixedly connected to the upper surface of the fixing ring, and a spring sheet is fixedly connected to the upper surface of the connecting plate.

[0015] The above technical solution achieves stable support and reset control for filter screen two, keeping it firm and not easily loosened during use, and providing reset force during disassembly, thus improving the ease of operation and the reliability of testing.

[0016] Preferably, both ends of the spring sheet are fixedly connected to a fixing post, and a locking block is slidably connected to the outer wall of the fixing post.

[0017] The above technical solution enables the locking block to slide flexibly and be reliably limited with the cooperation of the spring plate, making the filter screen two installed firmly and easy to disassemble and replace, thus improving the practicality of the device.

[0018] Preferably, a connecting block two is fixedly connected to the outer wall of the spring sheet, and the upper surface of the locking block is fixedly connected to the lower surface of the filter screen two.

[0019] The above technical solution achieves reliable fixation between the card block and the second filter screen, ensuring that the second filter screen remains stable and does not shift during use, while maintaining ease of installation and disassembly.

[0020] Preferably, a second spring is fixedly connected to the lower surface of the second connecting block, and one end of the second spring is fixedly connected to the upper surface of the connecting plate.

[0021] The above technical solution enables the automatic reset of filter screen 2, ensuring stable installation while facilitating quick restoration to its original position after disassembly, thus improving the convenience and reliability of the device.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by setting an exhaust component, the internal pressure of the material cylinder is effectively controlled. During the ventilation or pressurization process, when the internal air pressure reaches the set range, the pressure relief valve can release excess gas and discharge it through the pressure relief pipe, avoiding the instantaneous increase of internal pressure that could cause mortar to splash or cause operational hazards. At the same time, the filter screen effectively blocks impurities from being discharged with the airflow, ensuring the safety and reliability of the pressurization operation process. This solves the potential high-pressure jetting hazard that may occur when the top cover of the traditional mortar bleeding device is disassembled or pressurized, and improves operational safety and equipment controllability.

[0023] 2. In this utility model, a filter screen and a snap-on installation structure are provided inside the support base, including a spring plate, a fixing column, a locking block, and a connecting block, etc., so that the filter screen can be quickly installed or removed. The operator only needs to overcome the elasticity of the spring plate to snap the filter screen into the fixing ring. After use, it can be quickly removed for cleaning. This design not only simplifies the operation process and reduces the risk of cross-contamination, but also improves the efficiency and accuracy of water seepage measurement, and ensures the repeatability and reliability of mortar samples in water seepage testing.

Detailed Implementation

[0026] The following combination Figures 1-6 This application will be described in further detail below.

[0027] Reference Figure 1 - Figure 6 The present invention provides an embodiment of a mortar pressure bleeding instrument, including a support rod 1. The support rod 1 is used to support the structure of the entire mortar bleeding instrument, fix the support base 3 and the material cylinder 4 at an appropriate height, and at the same time leave enough space below for placing a water receiving container to ensure that the liquid can flow out smoothly during the test. A mortar bleeding component is provided above the support rod 1. The mortar bleeding component includes a material cylinder 4, which is used to hold the mortar sample to be tested and is the main container for the bleeding test. The material cylinder 4 is set above the support rod 1. A support seat 3 is fixedly connected to the upper surface of the support rod 1. A valve body 2 is fixedly connected to the inner wall of the support seat 3. The inner wall of the support seat 3 is threaded to the outer wall of the material cylinder 4. A top cover 5 is threaded to the outer wall of the material cylinder 4. The top cover 5 seals the material cylinder 4 to prevent mortar from splashing out during the test. A connecting block 11 is fixedly connected to the upper surface of the top cover 5. A pressure gauge 7 is fixedly connected to the inner wall of the connecting block 11. The pressure gauge 7 is used to monitor the air pressure in the material cylinder 4 in real time to ensure that the test pressure reaches the preset value, thereby ensuring the accuracy of the bleeding data. A connecting pipe 10 is fixedly connected to the outer wall of the connecting block 11. An air pipe 6 is fixedly connected to the outer wall of the connecting pipe 10. An exhaust component is provided on the inner wall of the top cover 5. The exhaust assembly includes a pressure relief valve 8. When the internal pressure of the material cylinder 4 is too high, the pressure relief valve 8 can manually release excess gas to prevent mortar splashing during operation and improve experimental safety. The outer wall of the pressure relief valve 8 is fixedly connected to the inner wall of the top cover 5. A threaded rod 12 is threadedly connected to the inner wall of the pressure relief valve 8. A rubber plate 14 is fixedly connected to the outer wall of the threaded rod 12. The rubber plate 14 fits against the inner wall of the pressure relief valve 8 to keep the internal environment of the spring-13 dry and reduce rusting of the spring-13. The outer wall of the threaded rod 12 is fitted with the spring-13. One end of the spring-13 is fixedly connected to the inner wall of the pressure relief valve 8, and the other end of the spring-13 is fixedly connected to the rubber plate 14. On the surface, a conical rubber block 15 is fixedly connected to one end of the threaded rod 12. The conical rubber block 15 contacts the sealing ring 16 to achieve airtight sealing of the inside of the material cylinder 4. When the pressure is too high, it can slide out of the inner wall of the sealing ring 16 to release the gas. A fixing block 17 is fixedly connected to the inner wall of the pressure relief valve 8. The sealing ring 16 is fixedly connected to the upper surface of the fixing block 17. The outer wall of the conical rubber block 15 is slidably connected to the inner wall of the sealing ring 16. A pressure relief pipe 9 is fixedly connected to the outer wall of the pressure relief valve 8. The pressure relief pipe 9 is used to safely discharge the released gas and prevent the pressure inside the material cylinder 4 from rising suddenly and causing danger. A filter screen 18 is fixedly connected to the inner wall of the pressure relief valve 8.

[0028] Specifically, the pressure gauge 7 monitors the internal air pressure of the material cylinder 4 in real time, ensuring that the mortar is uniformly pressurized under controlled air pressure. The main body of the mortar is intercepted by the filter screen 19, and the water is discharged from the valve body 2 under pressure, realizing the measurement of water seepage. The pressure relief valve 8 is activated when the air pressure exceeds the set range. The threaded rod 12 drives the rubber plate 14 to compress the spring 13, causing the conical rubber block 15 to release the seal and safely discharge excess gas through the pressure relief pipe 9. This prevents the mortar from splashing out or causing operational hazards due to excessive pressure inside the material cylinder 4. The filter screen 18 can block impurities from being discharged with the airflow, ensuring smooth gas discharge. This structure ensures uniform and stable pressure during the water seepage test, reliable measurement data, and improves operational safety. It effectively solves the spray risk that may occur when traditional devices lack a pressure relief mechanism.

[0029] Reference Figure 1 - Figure 6A fixing ring 22 is fixedly connected to the inner wall of the support base 3, and a filter screen 19 is slidably connected to the inner wall of the support base 3. The filter screen 19 is used to intercept the mortar body, ensuring that water can be smoothly discharged through the valve body 2 and preventing particles from entering the lower water collection device. A fixing block 20 is fixedly connected to the upper surface of the filter screen 19, and a handle 21 is rotatably connected to the inner wall of the fixing block 20. A connecting plate 23 is fixedly connected to the upper surface of the fixing ring 22, and a spring plate 24 is fixedly connected to the upper surface of the connecting plate 23. The spring plate 24 applies a restoring force to the locking block 28 through elasticity. To ensure the filter screen 219 is stable and easy to disassemble during installation, both ends of the spring plate 24 are fixedly connected to the fixing posts 25. The outer wall of the fixing posts 25 is slidably connected to the locking blocks 28. The outer wall of the spring plate 24 is fixedly connected to the connecting block 26. The upper surface of the locking block 28 is fixedly connected to the lower surface of the filter screen 219. The locking block 28 cooperates with the spring plate 24 and the fixing posts 25 to realize the locking and fixing and quick disassembly functions of the filter screen 219. The lower surface of the connecting block 26 is fixedly connected to the spring 27. One end of the spring 27 is fixedly connected to the upper surface of the connecting plate 23.

[0030] Specifically, during the mortar bleeding measurement process, filter screen 219 intercepts the main body of the mortar, allowing only water to pass through, thus ensuring the accuracy of the bleeding data. Operators use the locking block 28 and spring plate 24 to quickly install and securely fix filter screen 219. Spring 27 provides a restoring force to ensure no displacement or loosening occurs during measurement, reducing the risk of cross-contamination. The mortar inside the cylinder 4 is subjected to air pressure monitored by pressure gauge 7 and gravity. Water flows through filter screen 21 into the collection device below, achieving efficient separation. The handle 21 facilitates the removal and cleaning of filter screen 21, making equipment maintenance simple and quick. This structure improves testing efficiency, ensures stable and reliable bleeding measurement of mortar samples, and is safe and convenient to operate, contributing to improved experimental repeatability and data accuracy.

[0031] Working principle: When the mortar pressure bleeding instrument is needed, first fix the support base 3 with the support rod 1 to make enough space below to place the water receiving container. The bottom of the material cylinder 4 is installed with the support base 3 through the thread to ensure that it is fixed and stable. The top cover 5 is threaded on the top of the material cylinder 4. At the same time, the pressure gauge 7 in the connecting block 11 is connected to the air pipe 6 to connect to the external air source to ensure that the pressure measurement and air supply are smooth. During testing, the mortar to be tested is poured into the cylinder 4, and the top cover 5 is tightened to ensure the cylinder 4 is sealed. The air source is turned on, and air is introduced into the cylinder 4 through the air pipe 6, so that the pressure gauge 7 shows the preset pressure value. The pressure inside the cylinder 4 increases, and uniform pressure is applied to the mortar. The main part of the mortar is intercepted by the filter screen 19, while the water is discharged from the valve body 2 under pressure. During the water seepage test, when the internal air pressure rises to the set range, the pressure relief valve 8 drives the rubber plate 14 to compress the spring 13 through the threaded rod 12, so that the conical rubber block 15 slides out from the inner wall of the sealing ring 16, releasing the seal and discharging the excess gas through the pressure relief pipe 9. This prevents the mortar from splashing out or causing operational hazards due to the instantaneous increase in air pressure inside the cylinder 4. The filter screen 18 is located inside the pressure relief valve 8, which can prevent impurities from being discharged with the airflow, ensuring smooth gas discharge without affecting the measurement. This structure ensures the safety of the equipment when pressurizing and operating the top cover 5, and solves the spray risk that may occur when traditional devices lack a pressure relief mechanism. In addition, when measuring mortar bleeding, the filter screen 219 needs to be installed and adjusted. The operator presses the filter screen 219, causing the locking block 28 to overcome the elasticity of the spring plate 24 and squeeze the fixing post 25 so that the fixing post 25 is locked into the locking groove inside the locking block 28, and the filter screen 219 is locked into the fixing ring 22 in the support base 3. The spring 27 provides the restoring force to ensure that the filter screen 219 is installed firmly. This design allows the filter screen 219 to be quickly disassembled and installed, reducing operation steps, improving testing efficiency, reducing the risk of cross-contamination, and ensuring that the bleeding test of the mortar sample is accurate and reliable. Subsequently, the pressure change in the material cylinder 4 is monitored by the pressure gauge 7, and the air pressure supply is adjusted by the air pipe 6. Under the action of gravity and air pressure, the water in the mortar flows into the lower collection device through the filter screen 21. During the test, the pressure change and bleeding situation can be observed in real time. After the required time is completed, the air source is turned off, and the filter screen 21 is removed for cleaning by pulling the handle 21 to overcome the elasticity of the spring.
