[0002] Flat ceramic membrane is a new generation of ceramic membrane technology. It is mainly based on the "physical screening" theory. The permeability is different according to the different molecular diameters of the substances penetrating within a certain membrane pore size range.

[0003] In the manufacturing process of flat ceramic membrane filters, the bonding strength between the water collecting pipe and the flat ceramic membrane body is one of the key factors to ensure the long-term stable operation of the filter.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0030] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.
[0031] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.
[0032] The structure of the flat ceramic membrane element 100' is shown in the attached figure. Figure 1 As shown in the figure, it generally includes a flat ceramic membrane body 110' and two long trapezoidal water collecting pipes 120'. One of the water collecting pipes 120' has a water collecting interface 121'. The two ends of the flat ceramic membrane body 110' are respectively inserted into the water collecting pipe 120', and glue is applied to the joint to fix it. After the glue is cured, a cured sealing layer is formed. The viscosity strength of the glue on the water collecting pipe 120' after curing is one of the key factors to ensure the long-term stable operation of the filter.
[0033] This embodiment provides a device for detecting the bonding strength between a flat ceramic membrane water collecting pipe and glue, as shown in the attached Figure 2 and attached Figure 3As shown in . The flat ceramic membrane water collecting pipe and glue bonding strength detection device includes a pure water storage tank 100, an agitator 200, a first delivery pump 300, a second delivery pump 400 and a PLC control cabinet (not shown in the figure). In this embodiment, the PLC control cabinet first controls the second delivery pump 400 to extract pure water in the pure water storage tank 100 into the flat ceramic membrane element 100' to check whether the gap of the flat ceramic membrane element 100' is congested, whether the surface water discharge is normal, etc. Then the PLC control cabinet controls the second delivery pump 400 to extract the mixture of starch and pure water in the agitator 200 into the flat ceramic membrane element 100'. After the starch blocks the internal gap of the flat ceramic membrane element 100', the internal pressure can be increased. When the pressure inside the flat ceramic membrane element 100' continues to reach a certain value, the solidified sealing layer of the water collecting pipe 120' is damaged, and the phenomenon of water leakage occurs at the junction of the flat ceramic membrane body 110' and the water collecting pipe 120', thereby characterizing the bonding strength between the flat ceramic membrane water collecting pipe and the glue. Compared with the gas detection method in the prior art, the process of detecting the bonding strength of the flat ceramic membrane water collecting pipe and glue in the present embodiment is easier and the operation process is relatively simple.
[0034] Specifically, as attached Figure 2 and attached Figure 3 As shown in the figure, the upper part of the pure water storage tank 100 is provided with a water inlet pipe 110. The outer side of the lower part of the pure water storage tank 100 is provided with a drain pipe 120. An electronic level gauge (not shown in the figure) is also provided in the pure water storage tank 100. When the electronic level gauge is electrically connected to the PLC control cabinet, the pure water level height in the pure water storage tank 100 monitored by the electronic level gauge can be displayed in real time on the display screen of the PLC control cabinet. And when the pure water level height in the pure water storage tank 100 monitored by the electronic level gauge is lower than the lower warning limit, the buzzer of the PLC control cabinet issues an alarm. A first three-way joint 121 is provided at the drainage end of the drain pipe 120. As a result, the pure water flowing out of the first three-way joint 121 has two flow directions. That is, the pure water flows directly to the flat ceramic membrane body 110', and the pure water flows to the agitator 200.
[0035] The agitator 200 is mainly composed of a stirring tank 210, a stirring paddle 220 and a stirring motor 230, as shown in the attached Figure 2 and attached Figure 3As shown in . The top of the stirring tank 210 is open. Starch is added to the stirring tank 210 from the top of the stirring tank 210 in advance. The outer side of the bottom of the stirring tank 210 is a slurry discharge pipe 211. A first solenoid valve 212 is provided on the slurry discharge pipe 211. After the first solenoid valve 212 is electrically connected to the PLC control cabinet, the PLC control cabinet can control the opening or closing process of the slurry discharge pipe 211. The stirring motor 230 is arranged above the top of the stirring tank 210 along the axial center direction of the stirring tank 210. One end of the stirring paddle 220 is connected to the output shaft of the stirring motor 230, and the other end of the stirring paddle 220 extends to the vicinity of the bottom of the inner side of the stirring tank 210. After the stirring motor 230 is electrically connected to the PLC control cabinet, the start and stop process of the stirring motor 230 can be controlled by the PLC control cabinet. After the pure water flows into the stirring tank 210, it contacts with the starch, and is stirred and mixed by the stirring paddle 220 to form a mixture of starch and pure water in a suspended state. Furthermore, when the mixture of starch and pure water flows toward the flat ceramic membrane body 110 ′, the stirring motor 230 and the stirring paddle 220 maintain a continuous stirring working state to prevent starch precipitation.
[0036] As attached Figure 2 and attached Figure 3 As shown in the figure, the inlet end of the first delivery pump 300 is connected to a passage of the first three-way joint 121. The outlet end of the first delivery pump 300 is connected to the upper part of the stirring tank 210 to pump the pure water in the pure water storage tank 100 into the agitator 200. After the first delivery pump 300 is electrically connected to the PLC control cabinet, the control cabinet can control the start and stop process of the first delivery pump 300. A second solenoid valve 310 is arranged on the connecting pipeline between the first delivery pump 300 and the first three-way joint 121. After the second solenoid valve 310 is electrically connected to the PLC control cabinet, the PLC control cabinet can control the connection or disconnection between the first delivery pump 300 and the pure water storage tank 100. An electronic flow meter (not shown in the figure) is arranged on the connecting pipeline between the first delivery pump 300 and the stirring tank 210. After the electronic flow meter is electrically connected to the PLC control cabinet, the PLC control cabinet can control the linkage with the first delivery pump 300. For example, when the first delivery pump 300 is started, the electronic flow meter starts to measure. When the amount of pure water added to the mixing tank 210 measured by the electronic flow meter reaches the preset amount of pure water pre-input through the input keyboard of the PLC control cabinet, the first delivery pump 300 stops working. As a result, the solid content of the mixture of starch and pure water in the mixing tank 210 tends to be stable. Using the mixture of starch and pure water at this time as a detection reagent, the corresponding detection result is more reliable.
[0037] In this embodiment, the number of the second delivery pumps 400 can be two or one.
[0038] When there are two second delivery pumps 400, the inlet end of one second delivery pump 400 is connected to one end of the slurry discharge pipe 211, and a pressure-resistant hose 500 is provided at the outlet end of the second delivery pump 400. The inlet end of the other second delivery pump 400 is connected to the remaining passage of the first three-way connector 121, and a pressure-resistant hose 500 is also provided at the outlet end of the second delivery pump 400. A third solenoid valve 410 is provided on the connecting pipeline between the second delivery pump 400 and the first three-way connector 121. After the third solenoid valve 410 is electrically connected to the PLC control cabinet, the connection or disconnection between the second delivery pump 400 and the first three-way connector 121 can be controlled by the PLC control cabinet. Electronic pressure gauges are respectively provided on the two pressure-resistant hoses 500. After the electronic pressure gauges are electrically connected to the PLC control cabinet, the current pressure value can be displayed in real time on the display screen of the PLC control cabinet. The other ends of the two pressure-resistant hoses 500 can be connected to the water collection interface 121' respectively. After the two second delivery pumps 400 are electrically connected to the PLC control cabinet, the PLC control cabinet can control the two second delivery pumps 400 to extract pure water or a mixture of starch and pure water into the flat ceramic membrane element 100' for testing. When there are two second delivery pumps 400, semi-continuous testing can be performed, that is, pure water testing and starch and pure water mixture testing can be performed simultaneously, shortening the detection cycle.
[0039] As attached Figure 2 and 3 As shown in , when the number of the second delivery pump 400 is one, a second three-way joint 420 is provided at the inlet end of the second delivery pump 400. The other two passages of the second three-way joint 420 are respectively connected to one end of the slurry discharge pipe 211 and a passage of the first three-way connector 121. A third solenoid valve 410 is provided on the connecting pipeline between the second three-way joint 420 and the first three-way connector 121. After the third solenoid valve 410 is electrically connected to the PLC control cabinet, the connection or disconnection between the second delivery pump 400 and the first three-way connector 121 can be controlled by the PLC control cabinet. A pressure-resistant hose 500 is provided at the outlet end of the second delivery pump 400. An electronic pressure gauge is provided on the pressure-resistant hose 500. After the electronic pressure gauge is electrically connected to the PLC control cabinet, the current pressure value can be displayed in real time on the display screen of the PLC control cabinet. The other end of the pressure-resistant hose 500 can be connected to the water collection interface 121'. After the second delivery pump 400 is electrically connected to the PLC control cabinet, the PLC control cabinet can control the second delivery pump 400 to extract pure water or a mixture of starch and pure water into the flat ceramic membrane element 100' for testing. When the number of the second delivery pump 400 is one, the cost is relatively lower.
[0040] In this embodiment, in order to improve the safety during the test, the flat ceramic membrane water collecting pipe and glue bonding strength detection device also includes a test box 600. The top of the test box 600 is open. The internal length, width and depth of the test box 600 are respectively greater than the length, thickness and width of the flat ceramic membrane element 100'. As a result, the test box 600 can completely accommodate the flat ceramic membrane element 100' for safety protection, that is, the flat ceramic membrane element 100' can be completely immersed in the test box 600. Further, a group of brackets 610 are arranged at the bottom of the inner side of the test box 600 along the length direction of the flat ceramic membrane element 100'. The number of a group of brackets 610 is at least 2 to support the two ends of the length direction of the vertically placed flat ceramic membrane element 100'. The bracket 610 can be roughly in a "Y" shape, and the upper two arms of the "Y" shape can be used to clamp the two side surfaces of the flat ceramic membrane element 100'. Furthermore, fixing seats 620 are detachably provided on two long sides opposite to each other at the top of the test box 600, and there are four fixing seats 620 in total. Figure 4 As shown in , the lower part of the fixing seat 620 is an inverted "U"-shaped groove structure, which can be stuck on the top side wall of the test box 600 and can be positioned and fixed by locking screws 621. The top surface of the fixing seat 620 is an inclined surface, and the inclination direction of the inclined surface is toward the inner area of the test box 600. A camera 630 is set on the inclined surface of the fixing seat 620, and the shooting field of view of the camera 630 is the inner area of the test box 600. After the camera 630 is electrically connected to the PLC control cabinet, the video screen shot by the camera 630 can be stored in the memory of the PLC control cabinet, so that the technicians can view the damage process of the cured sealing layer on the flat ceramic membrane element 100' through the video. At the same time, the memory of the PLC control cabinet also stores detection related data such as detection time, flow, pressure, etc.
[0041] The use process of the flat ceramic membrane water collecting pipe and glue bonding strength detection device in this embodiment is as follows:
[0042] (1) As attached Figure 5 As shown in FIG. 1 , after the pressure-resistant hose 500 is connected to the flat ceramic membrane element 100 ′, the flat ceramic membrane element 100 ′ is vertically placed on the bracket 610 in the test box 600. The positions of the four fixing seats 620 at the open top of the test box 600 are adjusted so that the four cameras 630 are respectively directed to the positions of the cured sealant layers on the two sides of the flat ceramic membrane element 100 ′.
[0043] (2) The first solenoid valve 212 and the second solenoid valve 310 remain closed, and the third solenoid valve 410 is opened. The second delivery pump 400 is started to extract the pure water in the pure water storage tank 100 into the flat ceramic membrane element 100', and check whether the gap of the flat ceramic membrane element 100' is congested, whether the water discharge from the surface is normal, etc. If the pure water test result is abnormal, the flat ceramic membrane element 100' is directly determined to be unqualified. If the pure water test result is normal, proceed to the next step.
[0044] (3) The first solenoid valve 212 and the third solenoid valve 410 remain closed, the second solenoid valve 310 is opened, and the first delivery pump 300 is started to extract a fixed amount (for example, 30L) of pure water in the pure water storage tank 100 into the stirring tank 210, and mix it with a fixed amount (for example, 3kg) of starch pre-put into the stirring tank 210. After the mixture of starch and pure water in the suspended state is configured, the stirring state is maintained, and the first solenoid valve 212 is opened. The second delivery pump 400 is started to extract the mixture of starch and pure water in the stirrer 200 into the flat ceramic membrane element 100', and the starch blocks the internal gap of the flat ceramic membrane element 100' to increase the internal pressure. When the pressure inside the flat ceramic membrane element 100' continues to reach a certain value, the solidified sealing layer of the water collecting pipe 120' is damaged, and water leakage occurs at the junction of the flat ceramic membrane body 110' and the water collecting pipe 120', thereby indicating the bonding strength between the flat ceramic membrane water collecting pipe and the glue. By viewing the video images obtained by the four cameras 630 during the test, the damage process of the solidified sealing layer on the flat ceramic membrane element 100 ′ can be analyzed, so as to facilitate further adjustments in terms of the composition of the glue, the glue dispensing process, etc.
[0045] In this embodiment, the preparation process of the mixture of starch and pure water can also be performed simultaneously with the pure water testing operation.
[0046] In this embodiment, automatic control is performed through a PLC control cabinet, and the degree of intelligence is improved. It should be noted that the control logic of the PLC control cabinet in this embodiment can be implemented by conventional known logic setting means, and there is no need to create a new control logic. When centralized control of the PLC control cabinet is not required, manual control can also be adopted one by one.
