Description

Technical Field

[0001] This utility model relates to the technical field of flow guide cloth detection, and in particular to a flow guide cloth porosity detection device. Background Technology

[0002] Typical methods for porosity detection include mercury intrusion porosimetry, gas adsorption, percolation, and image analysis. Mercury intrusion porosimetry forces mercury into the pores under high pressure, accurately determining pore size distribution, but carries the risk of mercury contamination. Gas adsorption utilizes nitrogen adsorption-desorption properties to analyze microporous structure, suitable for research but time-consuming. Percolation rapidly assesses porosity based on liquid permeation rate or area, is simple to operate and low-cost, suitable for production line screening. Image analysis uses microscopes or CT scans to directly observe pore morphology, providing a clear view, but the equipment is expensive. In practical applications, the appropriate method must be selected based on a comprehensive consideration of accuracy requirements, detection efficiency, and cost.

[0003] However, in the process of testing the pore filter of the flow guide cloth, the installation steps of the flow guide cloth usually require bolts to install the flow guide cloth onto the test position on the test base, and then install the pressurizing equipment and the test base, which leads to a reduction in the overall testing efficiency.

[0027] Example 1

[0028] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a detection mechanism 100 and a clamping mechanism 200 to shorten the preparation time before detection.

[0029] The testing mechanism 100 includes a booster 101, with a test seat 102 threadedly connected to the bottom of the booster 101. A placement ring 103 is provided inside the test seat 102, and the surface of the placement ring 103 is fixedly connected to the inner wall of the test seat 102. The clamping mechanism 200 includes a clamping ring 201, with the bottom of the clamping ring 201 movably connected to the top of the placement ring 103. A lower pressure sleeve 202 is fixedly connected to the top of the clamping ring 201. Several lower pressure sleeves 202 are provided and are distributed in a ring at equal intervals. A pressurizing component 203 is fixedly connected to the bottom of the inner wall of the lower pressure sleeve 202. A sealing component 204 is fixedly connected to the bottom of the clamping ring 201.

[0030] Specifically, during the testing process, the booster 101 is threadedly connected to the test seat 102, and the placed guide cloth is installed simultaneously, thereby shortening the preparation time and eliminating the need for a separate installation process for the guide cloth.

[0031] Furthermore, before testing, the user can place the guide cloth to be tested above the placement ring 103 inside the testing seat 102, and then thread the booster 101 to the testing seat 102. During the threaded connection between the booster 101 and the testing seat 102, the booster 101 will also drive the lower sleeve and clamping ring 201 to rotate and move downwards. Thus, the placed guide cloth is installed synchronously with the installation of the booster 101, thereby shortening the preparation time and eliminating the separate installation process for the guide cloth.

[0032] Example 2

[0033] Reference Figures 1-6 In the second embodiment of this utility model, a pressurizing component 203 and a sealing component 204 are provided to improve the installation strength of the guide cloth and the sealing effect after installation.

[0034] The pressurizing assembly 203 includes a pressurizing spring 203a, one end of which is fixedly connected to the bottom of the inner wall of the lower pressure sleeve 202, and the other end of which is fixedly connected to a lower pressure rod 203b. The top of the lower pressure rod 203b is fixedly connected to the top of the inner wall of the booster 101. The sealing assembly 204 includes an insert ring 204a, the top of which is fixedly connected to the bottom of the clamping ring 201. The top of the placement ring 103 has an insert groove 204b, and the inner wall of the placement ring 103 is fixedly connected to a sealing ring 204c.

[0035] Specifically, during the installation of the booster 101 and the detection seat 102, the elastic force of the pressure spring 203a can help improve the installation strength of the guide cloth. During the clamping process of the clamping ring 201 clamping the guide cloth on the placement ring 103, the inlay ring 204a can improve the sealing effect on the outside of the guide cloth and prevent leakage. At the same time, the rubber sealing ring 204c is used to further improve the sealing effect.

[0036] Furthermore, during the installation of the booster 101 and the detection seat 102, the elastic force of the pressure spring 203a can push the lower pressure sleeve 202 to contact the top of the guide cloth in advance, thereby achieving pre-fixation of the guide cloth. At the same time, as the booster 101 continues to rotate and move downward, it will drive the lower pressure rod 203b to compress the pressure spring 203a, causing the pressure generated by the pressure spring 203a on the guide cloth to gradually increase, thereby helping to improve the installation strength of the guide cloth. During the process of clamping the guide cloth on the placement ring 103 by the clamping ring 201, the clamping ring 201 will also drive the inlay ring 204a to squeeze part of the guide cloth at the position corresponding to the inlay groove 204b into the inlay groove 204b. The inlay ring 204a can improve the sealing effect on the outside of the guide cloth and avoid leakage. In this process, the rubber sealing ring 204c is used to further improve the sealing effect.

[0037] The remaining structure is the same as that in Example 1.

[0038] Example 3

[0039] Reference Figures 1-6 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a flow guide cloth porosity detection device.

[0040] Before testing, the user can place the guide cloth to be tested above the placement ring 103 inside the testing seat 102, and then thread the booster 101 to the testing seat 102. During the threaded connection between the booster 101 and the testing seat 102, the booster 101 will also drive the lower sleeve and clamping ring 201 to rotate and move downwards. Thus, the placed guide cloth is installed synchronously with the installation of the booster 101, thereby shortening the preparation time and eliminating the separate installation process of the guide cloth.

[0041] During the installation of the booster 101 and the detection seat 102, the elastic force of the pressure spring 203a can push the lower pressure sleeve 202 to contact the top of the guide cloth in advance, thereby achieving pre-fixation of the guide cloth. At the same time, as the booster 101 continues to rotate and move downward, it will drive the lower pressure rod 203b to squeeze the pressure spring 203a, so that the pressure of the pressure spring 203a on the guide cloth gradually increases, thereby helping to improve the installation strength of the guide cloth.

[0042] During the process of clamping the guide cloth on the placement ring 103 by the clamping ring 201, the clamping ring 201 will also drive the inlay ring 204a to squeeze part of the guide cloth at the position corresponding to the inlay groove 204b into the inlay groove 204b. The inlay ring 204a can improve the sealing effect on the outside of the guide cloth and prevent leakage. At the same time, the rubber sealing ring 204c is used to further improve the sealing effect.

[0043] During the up-and-down movement of the pressure rod 203b inside the pressure sleeve 202, the sliding cooperation between the limiting block 203d and the limiting groove 203c can limit the maximum movement space of the pressure rod 203b, thus preventing the pressure rod 203b from separating from the pressure sleeve 202.

[0044] When the external test liquid is injected into the booster 101 through the one-way valve 107 and pressurized to test the porosity of the guide cloth, the user can see the test liquid in the test seat 102 through the observation window 105 embedded in the first observation slot 104, and can also observe the penetration of the test liquid under the guide cloth through the second observation slot 106. In addition, as the lower pressure sleeve 202 rotates and moves downward, it will also drive the scraper 203e to scrape and clean the second observation window 105 to ensure the observation effect.

[0045] In summary, when a user needs to use the testing mechanism 100 for testing, the guide cloth is placed inside the testing mechanism 100, and the clamping mechanism 200 is driven simultaneously during the installation of the testing mechanism 100 to clamp and position the guide cloth to be tested. This allows the guide cloth to be installed at the same time as the testing mechanism 100, shortening the preparation time before testing.
