Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane production technology, specifically to an automatic sampling and testing instrument for the concentration of monomers in the water-oil phase. Background Technology

[0002] Reverse osmosis membrane filtration is gaining increasing popularity in the water treatment market due to its energy efficiency and high performance. The reverse osmosis membrane is prepared by using a phase inversion method to fabricate an ultrafiltration base membrane on a supporting nonwoven fabric, followed by an interfacial polymerization reaction on the base membrane surface to prepare a polyamide functional layer. In actual production, the monomer concentrations in the water and oil phases are constantly changing. To ensure production stability, it is necessary to test the monomer concentrations in both phases. Manual sampling and testing is inefficient and has long testing intervals, presenting certain limitations. Therefore, we have developed an automatic sampling and testing instrument for the monomer concentrations in the water and oil phases. Utility Model Content

A waste liquid discharge port 207 is provided at the bottom of the dust cover 2 located inside the housing 1. Multiple sets of rotating cuvettes 206 are arranged around the inner circumference of the rotating frame 202. A jacket 205 is provided outside the cuvettes 206. Rotating roller groups 204 are provided on both sides of the jacket 205. Each rotating roller group 204 has two rotating rollers rotatably connected together. One rotating roller is connected to the jacket 205, and the other rotating roller is connected to the inner wall of the rotating frame 202. A positioning component is also provided between the two rotating rollers. The inner wall of the dust cover 2 is provided with waste liquid pouring pin 208, ethanol filling pipe 213, cuvette aligning pin A209, ethanol pouring pin 210, cuvette drying air outlet 211, cuvette aligning pin B212, and test solution filling pipe 214 in a clockwise direction.

[0020] In practice, the side wall of the rotating frame 202 has the same number of openings as the cuvette 206, and the test hole 201 is directly below the top cuvette 206, so that the light from the tester 5 can pass through the test hole 201 and the openings in the side wall of the rotating frame 202.

[0021] In practice, the outer wall of the dust cover 2 is provided with an inspection port 203. The inspection port 203 adopts a detachable sealing cover design and is equipped with a transparent observation window or a quick-opening structure (such as a buckle / knob) to facilitate maintenance personnel to conduct internal inspections or emergency handling without removing the dust cover.

[0022] In specific implementation, a motor 4 is installed on the upper surface of the box 1 located on one side of the dust cover 2. The output end of the motor 4 passes through the dust cover 2 and is connected to the rotating frame 202. The rotation of the rotating frame 202 can be easily driven by the motor 4.

[0023] In practice, the positioning component includes two sets of 180-degree aligning ball holders and elastic elements that provide elasticity to the positioning ball holders. The inner sides of the two rotating rollers each have two 180-degree aligning receiving grooves. The two elastic elements are respectively located in the two receiving grooves. One end of one elastic element is connected to the aligning ball holder, and the aligning ball holder extends into the other receiving groove and contacts the other elastic element. With the cooperation of the positioning component, the cuvette 206 can be easily fixed after rotating 180 degrees.

[0024] In practice, the waste liquid pouring pin 208 and the cuvette aligning pin B212 are respectively located at the rightmost and leftmost ends of the inner wall of the dust cover 2.

[0025] In practice, a waste liquid collection box 3 is installed at the bottom of the inner cavity of the box 1, corresponding to the waste liquid discharge port 207, for the centralized collection of waste liquid.

[0026] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows:

[0027] The test solution is added to the cuvette 206 through the test solution filling pipe 214. The motor 4 drives the rotating frame 202 to rotate at a suitable angle until it stops rotating in the test area. After the test is completed, it continues to rotate until it touches the waste liquid pouring pin 208. The rotating roller flips over, the cuvette 206 is inverted, and the test solution is poured out. It continues to rotate until it touches the cuvette returning pin A209, and the cuvette returns to its upright position. It then rotates until it stops rotating below the ethanol filling pipe 213. After adding ethanol, it continues to rotate until it touches the ethanol pouring pin 210. The cuvette 206 flips over and the ethanol is poured out. It continues to rotate until it reaches the cuvette drying air outlet 211, then stops rotating to dry the alcohol. It then continues to rotate until it touches the cuvette returning pin B212, and the cuvette 206 returns to its upright position. It then rotates again to the test solution filling pipe 214 to begin the next round of testing.
