Description

Technical Field

[0001] The present invention relates to the technical field of water quality analysis and detection, and more specifically, to a full-automatic SDI analyzer. Background Art

[0002] A water quality analyzer is a water quality monitoring tool that can automatically monitor various water quality parameters in real time. In the water treatment industry, it is used to evaluate the quality of raw water, reverse osmosis water, ultrafiltration water, etc., and guide the optimization and adjustment of water treatment processes. Electronics industry: In the process of electronic chip manufacturing, the quality requirements for ultrapure water are extremely high. SDI analyzers can be used to monitor the degree of contamination of ultrapure water.

[0003] At present, when testing water quality, water samples are usually passed through a filter membrane with a specific pore size, usually 0.45 microns, under a specific pressure. This pore size can block most suspended solids and colloids while allowing water to pass through. However, as time goes by, more and more suspended solids and colloids will accumulate on the filter membrane, causing the flow rate to gradually decrease. At the same time, it is not easy to quickly replace the membrane, resulting in inaccurate analysis and testing. Summary of the invention

[0004] In order to overcome the above defects of the prior art, the present invention provides a fully automatic SDI analyzer, aiming to solve the problems raised in the above background technology.

[0005] The present invention provides the following technical solution: a fully automatic SDI analyzer, comprising an analyzer body, wherein a conversion detection component is provided on the analyzer body; The conversion detection assembly includes a support liner frame arranged at the top of the inner cavity of the analyzer body, the inner wall bottom of the support liner frame is installed with a support frame by bolts, the inner wall bottom of the support frame is penetrated by a first frame opening, a flow velocity sensor for detection is clamped in the first frame opening, a second frame opening is opened on one side of the surface of the first frame opening, and a storage tube is arranged at the bottom of the second frame opening. A membrane loading block is arranged in the support frame, a guide tube for guiding is arranged on the top of the membrane loading block, the guide tube is installed on the support inner lining frame through a clamp, a plurality of membranes are arranged in the guide tube, the membranes include a bottom ring, and each bottom ring is provided with a sealing ring, and a filter membrane is arranged in the middle of the sealing ring; The guide tube has third openings on both sides of its surface, and each of the third openings has a micro motor embedded therein. A rotating shaft is fixedly disposed at the output end of each of the two micro motors, and a plurality of baffles are plugged into the outer side of each of the rotating shafts, and one end of the baffle extends to the bottom of the diaphragm. It can be seen that in the above technical solution, the second screw drive module drives the diaphragm loading block to move on the support frame. When the diaphragm loading block moves, it drives the bottom ring, the sealing ring and the filter membrane at the bottom of the guide tube to move, so that the diaphragm loading block extends to the top of the first frame opening and is connected to the first frame opening, so as to realize the function of loading the diaphragm. The second screw drive module drives the diaphragm loading block to slide continuously in the support frame, so that the diaphragm loading block can be connected to the second frame opening, so that the diaphragm is discarded after reaching the specified position and falls into the storage tube. The second screw drive module drives the diaphragm loading block to reset, and transports the remaining diaphragms in the guide tube to the bottom of the valve one by one, so as to facilitate the continuous operation of the device. Optionally, in a possible implementation manner, a support seat is provided on one side of the support frame, the support seat is mounted on the support liner frame by bolts, a column is mounted on one side of the top of the support seat by bolts, a slide groove is provided on the column, a slider is slidably connected in the slide groove, a first screw transmission module for driving the slider to move up and down is provided on the top of the column, a connecting block is mounted on the slider by bolts, a slide groove is plugged at the bottom of the connecting block, an air release pipe for water inlet is provided on the valve, a water injection pipe for drainage is provided at the bottom of the air release pipe, the air release pipe and the water injection pipe are both connected to the valve, and a one-way valve is provided at the connection between the air release pipe and the water injection pipe and the valve; It can be seen that in the above technical solution, the first screw transmission module is started to drive the slider to drive the connecting block and the valve to move through the guide of the slide groove, and the valve can be plugged into the sealing ring. The sealing ring ensures that the water flow delivered by the valve is in direct contact with the filter membrane, and water pressure leakage is avoided. The water source is delivered to the valve through the water injection pipe, and the air between the valve and the sealing ring can be discharged through the air release pipe to avoid the air in the valve. The test result will be affected. After the water is discharged from the valve and contacts the filter membrane, it is sensed by the flow rate sensor, and the water can be delivered to the water storage tray for storage. The timing is started through the control screen with a timing accuracy of milliseconds. The corresponding time of the initial fixed water flow is calculated, and the timing starts again after filtering for a certain period of time to calculate the time required to collect the same amount of water.

[0006] Optionally, in a possible implementation, one side of the surface of the analyzer body is movably connected to a cabinet door via a hinge, and a control screen is provided on the cabinet door. A second screw transmission module for driving the displacement of the diaphragm loading block is provided at one end of the support frame, and the diaphragm loading block is slidably connected to the support frame.

[0007] Technical effects and advantages of the present invention: 1. The present invention drives the diaphragm loading block to move on the support frame through the second screw drive module. When the diaphragm loading block moves, the bottom ring, the sealing ring and the filter membrane at the bottom of the guide tube are driven to move, so that the diaphragm loading block extends to the top of the first frame opening and is connected with the first frame opening, thereby realizing the function of loading the diaphragm and ensuring the accuracy of the diaphragm during transportation; 2. The present invention drives the slider through the first screw transmission module to drive the connecting block and the valve to move through the guide of the slide groove, and enables the valve to be plugged into the sealing ring, so that the water flow delivered by the valve is directly in contact with the filter membrane through the sealing ring, and also avoids water pressure leakage and inaccurate detection; 3. The ventilation water source of the present invention is delivered to the valve through the water injection pipe, and the air between the valve and the sealing ring can be discharged through the air release pipe to avoid the air in the valve affecting the test results. After the water flows through the valve and contacts the filter membrane, it is sensed by the flow rate sensor, and the water can be delivered to the water storage tray for storage. By calculating the corresponding time of the initial fixed water flow, and starting the timing again after filtering for a certain period of time, the time required to collect the same amount of water is calculated to obtain the test results; 4. The present invention drives the diaphragm loading block to slide continuously in the support frame through the second screw transmission module, so that the diaphragm loading block can be connected with the second frame port, so that the diaphragm is discarded after reaching the specified position and falls into the storage tube. The second screw transmission module drives the diaphragm loading block to reset, and the remaining diaphragms in the guide tube are transported to the bottom of the valve one by one, so that the device can work continuously, and the rotation of the shaft drives each baffle rod to rotate at the same time, so that the diaphragm at the bottom loses its limit and is easy to be discharged from the guide tube, and the remaining baffle rods can extend to the bottom of the remaining diaphragms one by one to support them, so as to prevent the diaphragms from falling and make them more convenient to load; In summary, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, when the diaphragm loading block is displaced, the bottom ring, the sealing ring and the filter membrane at the bottom of the guide tube are driven to be displaced, so that the diaphragm loading block extends to the top of the first frame opening and is connected to the first frame opening, so as to realize the function of loading the diaphragm. The valve can be plugged into the sealing ring, and the sealing ring ensures that the water flow delivered by the valve directly contacts the filter membrane, and also avoids water pressure leakage. The air between the valve and the sealing ring can be discharged through the vent pipe, so as to avoid that the air in the valve will affect the test result. After the water flow is discharged through the valve and contacts the filter membrane, it is sensed by the flow rate sensor, and the water can be transported to the water storage tray for storage. By calculating the corresponding time of the initial fixed water flow, and starting the timing again after filtering for a certain period of time, the time required to collect the same amount of water is calculated to obtain the test result, and the second screw transmission module drives the diaphragm loading block to reset, and the remaining diaphragms in the guide tube are transported to the bottom of the valve one by one, so as to facilitate the continuous operation of the device.
