Description

Technical Field

[0001] The utility model belongs to the technical field of plate detection, and particularly relates to a porosity detection device for plates. Background Technique

[0002] Porosity is a physical quantity that measures the ratio of the internal pore volume to the total volume of a material, directly reflecting the structural characteristics and properties of the material. In the field of plates, the size and distribution of porosity have important effects on the mechanical properties, thermal conductivity, permeability, etc. of the plates. Therefore, accurately measuring the porosity of plates is of great significance for optimizing the plate production process, controlling product quality, and developing new plates.

[0003] The immersion method is a commonly used method for testing the porosity of materials. It mainly uses the fact that after the plate is immersed in a liquid, the liquid can fill the pores inside the plate to reach a saturated state. By measuring the weight change of the plate before and after immersion, the porosity of the plate can be indirectly calculated. The time required to immerse the plate to reach a saturated state is a key factor. For some plates with larger pores and better permeability, they may reach a saturated state in a relatively short time, but for those plates with smaller pores and a compact structure, a longer immersion time may be required, and long-term immersion will reduce the efficiency of porosity detection.

[0030] As Figure 1 —3 shows, the specific scheme of the embodiment is as follows: A porosity detection device for a plate, including a porosity tester body 1, and an auxiliary component 2 is provided on the porosity tester body 1;

[0031] The auxiliary component 2 includes a bottom plate 21 fixedly installed on the side wall of the porosity tester body 1. The width of the bottom plate 21 is the same as the width of the porosity tester body 1. An immersion cylinder 22 is fixedly installed on the upper surface of the bottom plate 21. The immersion cylinder 22 is cylindrical. An observation window 221 is provided on the side wall of the immersion cylinder 22. The setting of the observation window 221 can observe the water inside the immersion cylinder 22. A drain pipe 222 is communicated with the outside of the immersion cylinder 22. The setting of the drain pipe 222 can discharge the water inside the immersion cylinder 22.

[0032] A support plate 23 and an airbag 24 are installed on the inner side wall of the immersion cylinder 22. The airbag 24 is circular, and the outer side wall of the airbag 24 is bonded to the inner side wall of the immersion cylinder 22. The airbag 24 is located above the support plate 23. The inner ring diameter of the support plate 23 is smaller than the inner ring diameter of the immersion cylinder 22. An air inlet pipe 241 is communicated with the outside of the airbag 24. The other end of the air inlet pipe 241 penetrates and extends to the outside of the immersion cylinder 22. The other end of the air inlet pipe 241 is communicated with a gas supply device. The setting of the air inlet pipe 241 can supply gas to the airbag 24, so that the airbag 24 seals the edge of the plate, avoiding the water above the plate from seeping out from the edge of the plate;

[0033] The upper end of the soaking cylinder 22 is provided with an end cover 25. The upper surface of the end cover 25 is communicated with an exhaust pipe 251. Hand valves 252 are communicated with both the exhaust pipe 251 and the drain pipe 222. The setting of the hand valves 252 can control the opening and closing of the exhaust pipe 251 and the drain pipe 222. One end of the end cover 25 close to the soaking cylinder 22 is fixedly connected with positioning columns 254. The number of the positioning columns 254 is four and they are symmetrically distributed. A positioning groove 223 is opened at one end of the soaking cylinder 22 close to the positioning columns 254. The positioning columns 254 are located inside the positioning groove 223. The cooperation between the positioning columns 254 and the positioning groove 223 enables the end cover 25 to be positioned and installed. The lower end of the end cover 25 is fixedly connected with a sealing gasket 253. The lower end of the sealing gasket 253 is attached to the upper end of the soaking cylinder 22. The setting of the sealing gasket 253 can seal the connection between the end cover 25 and the soaking cylinder 22.

[0034] An adjusting member 26 is provided on the upper surface of the bottom plate 21. The adjusting member 26 includes an electric push rod 261 fixedly installed on the upper surface of the bottom plate 21. The output end of the electric push rod 261 is rotationally connected with a mounting seat 262. The mounting seat 262 is rectangular. A through hole is opened on the side wall of the mounting seat 262. The upper end of the mounting seat 262 is fixedly connected with a handle 263. The setting of the handle 263 can drive the mounting seat 262 to rotate. A connecting pipe 27 communicated with the end cover 25 is installed on the adjusting member 26. The connecting pipe 27 is a metal pipe. The connecting pipe 27 is located inside the through hole, and a fixing bolt for limiting the connecting pipe 27 is threadedly connected to the side wall of the mounting seat 262. The cooperation between the fixing bolt and the through hole can disassemble the connecting pipe 27. A pressure pump 28 communicated with the connecting pipe 27 is fixedly installed on the upper end surface of the bottom plate 21. The pressure pump 28 is fixedly connected with the bottom plate 21. The output end of the pressure pump 28 is communicated with a delivery pipe 281. The other end of the delivery pipe 281 is threadedly connected to the connecting pipe 27. By pressurizing, the water absorption rate of the board cannot be increased, which further indicates that the porosity of the board has not changed. This is because there is a positive correlation between the water absorption rate and the porosity. Therefore, pressurizing can only increase the water absorption speed of the board;

[0035] Example two, as Figure 2 shown, change its airbag 24 to a semi-circular shape so that the airbag 24 limits and fixes both sides of the board. Close the exhaust pipe 251 and the drain pipe 222 through the hand valve 252. Start the water supply and pressurization treatment of the pressure pump 28 so that the board is located in the full-water soaking cylinder 22. Through the pressurization of the pressure pump 28, the board absorbs water under a pressurized environment.

[0036] The working principle of the above embodiments is:

[0037] 1. Prepare a test plate, place it on the porosity tester body 1, and record its mass;

[0038] 2. The electric push rod 261 is started by the control device on the porosity tester body 1, so that the electric push rod 261 drives the end cover 25 to move upward, and then the handle 263 drives the end cover 25 to rotate;

[0039] 3. Place the test plate on the support plate 23, and start the air supply device to expand the airbag 24 to seal the four sides of the test plate;

[0040] 4. The electric push rod 261 drives the end cover 25 and the soaking tube 22 to close, and the pressure pump 28 is started, so that the water is continuously pressurized to the inside of the soaking tube 22 through the pressure pump 28, and a certain volume of water is delivered;

[0041] 5. After continuous pressurized water delivery for a period of time, observe the water volume on the inner bottom wall of the soaking cylinder 22 through the observation window 221 to ensure that the plate is saturated;

[0042] 6. Take out the saturated board and immediately wipe off the moisture on the surface of the board;

[0043] 7. Place the saturated plate on the porosity tester body 1 to weigh the mass and record it;

[0044] 8. Calculate the porosity: Porosity = (mass before immersion - mass after immersion) / volume of immersion liquid.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
