Description

Technical Field

[0001] The invention relates to a device and a method for testing the adsorption performance of porous ceramic materials, and belongs to the technical field of ceramic gap testing. Background Art

[0002] The porosity of ceramics has an important impact on product performance. At present, it is difficult to directly measure the porosity of ceramics because the bonding force of ceramics is very weak. For some ceramics with specific functions, only by ensuring a certain porosity can they play some of their functions, such as water seepage and filtration. Therefore, the porosity must be considered in the design of ceramic components.

[0003] The Chinese patent application number CN202321831035.0 discloses a ceramic porosity tester, including a bracket, a test mechanism and a placement mechanism, wherein the test mechanism is arranged at the bottom of the bracket, the placement mechanism is arranged at the top of the bracket, the placement mechanism is located above the test mechanism, the test mechanism includes a test water tank, and the placement mechanism includes a placement clip for placing the product to be tested, and the placement clip slides up and down in the test water tank. The present invention immerses the test sample in water to ensure that the sample is in a saturated state, and obtains the measurement data necessary for calculating the ceramic porosity by recording the water level changes of the test mechanism, thereby reducing certain errors and making the equipment simple to operate.

[0004] When testing ceramic samples in the above scheme, the ceramic samples need to be placed on the storage clamps for fixation to prevent them from falling into the water tank during the test. However, the use of the storage clamps to fix the ceramic samples can easily cause the ceramic samples to be squeezed by the pressure of the storage clamps, causing the gaps in the ceramic samples to shrink, making the data less accurate when testing the water permeability. At the same time, after the samples enter the water, due to their different densities, they need to remain still for a period of time so that the ceramic samples become saturated with water. However, this not only increases the waiting time of the testers, but also reduces the continuity of continuous testing.

[0005] Therefore, a new porous ceramic material adsorption performance testing device and method are provided to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a porous ceramic material adsorption performance testing device and method in order to solve the above-mentioned problem.

One end of the rod 6 is fixedly connected, the solenoid valve 8 is fixedly installed at the lower part of the conical water tank body 1, the fixed side plate 9 is fixedly installed on the inner wall of the conical water tank body 1, the artificial electronic detection water gauge 10 is fixedly installed on the outer surface of the fixed side plate 9, the movable frame 11 slides between the inner and outer walls of the lifting plate 5, the vibration component 2 is arranged on the upper part of the lifting plate 5, the clamping component 3 is installed inside the movable frame 11, and the inner wall cleaning component 12 is arranged inside the conical water tank body 1. The clamping component 3 can be placed on the ceramic material to be tested to avoid inaccurate testing caused by fixed clamping.

[0028] like Figure 2-Figure 3As shown, the vibration assembly 2 includes a fixed mounting plate 201 fixedly mounted on the upper part of the lifting plate 5, a stepper motor 202 is fixedly mounted on the side wall of the fixed mounting plate 201, a rotating shaft 203 is fixedly mounted on the output end of the stepper motor 202, a rotating plate 204 is fixedly mounted on the outer surface of the rotating shaft 203, a rotating connecting plate 205 is rotatably connected to the outer surface of the rotating shaft 203, a protruding rod 206 is fixedly mounted on the outer surface of the rotating connecting plate 205, a connecting rod body 207 is fixedly mounted on the outer surface of the rotating connecting plate 205, a movable rod 208 is rotatably connected to the outer surface of the connecting rod body 207, and the lower surface of the movable rod 208 is fixedly mounted on the outer surface of the rotating connecting plate 205. The movable frame 11 is hinged at the top of the movable frame 11, and a fixed mounting plate 209 is installed horizontally inside the movable frame 11. A spring 210 is installed between the mounting plate 209 and the lifting plate 5. The user fills water into the conical water tank body 1 to make preliminary preparations. When the preparations are completed, the ceramic material to be tested is placed in the placement shell 308, and the cylinder 301 is turned on to move the moving block 304. The moving block 304 moves to move the hinge rod 307. The hinge rod 307 moves to move the grippers 305 to move to each other, and the grippers 305 move to move the placement shell 308 to move to each other, so that the ceramic material placed in the placement shell 308 is placed. The ceramic material is fully stretched, avoiding the problem that the ceramic sample is squeezed by the pressure of the placement clamp, causing the ceramic sample gap to shrink, so that the data is not accurate enough when testing the water permeability. After the ceramic material is placed, the motor 7 is turned on to drive the threaded rod 6 to rotate, and the threaded rod 6 rotates to move the lifting plate 5 downward, and the lifting plate 5 moves downward to move the movable frame 11 downward. When the movable frame 11 moves downward, it drives the clamping hand 305 and the placement shell 308 to move downward.

The clamping hands 305 are close to each other and the placement shell 308 is close to each other, so that the ceramic material placed in the placement shell 308 is fully stretched, and the problem of the ceramic sample being squeezed by the pressure of the placement clamp, resulting in the reduction of the gap of the ceramic sample and the inaccurate data when testing the water permeability, is avoided. Water flows into the placement shell 308 through the initial holes.

[0030] like Figure 6 As shown, the inner wall cleaning component 12 includes a circular plate 1201 sliding inside the conical water tank body 1, a screw rod 1202 is rotatably connected inside the fixed side plate 9, the inner part of the circular plate 1201 is screwed to the outer surface of the screw rod 1202, and a servo motor 1203 is fixedly installed on the upper part of the fixed side plate 9. The output end of the servo motor 1203 penetrates the upper part of the fixed side plate 9 and is fixedly connected to one end of the screw rod 1202. After the test is completed, the user turns on the servo motor 1203 to drive the screw rod 1202 to rotate, and the screw rod 1202 rotates to move the circular plate 1201. When the circular plate 1201 moves, the inner wall of the conical water tank body 1 is cleaned to make the water quality cleaner.

The water absorption rate of the ceramic is measured by the water level drop scale to see if it meets the standard. If the gap of the ceramic material is too large, the water level will drop or quickly to indicate that the gap is large. If the water level drops too slowly, it will indicate that the gap is too small. The test is over. After the test is over, the motor 7 is turned on to control the lifting plate 5 and the clamping component 5 to rise and move out of the conical water tank body 1, so that the user can remove the tested ceramic sample conveniently.
