Description

Technical Field

[0001] This invention relates to the field of instrumental analysis technology, and more specifically to an interference removal device for ion chromatography detection of high-salt wastewater. Background Technology

[0002] In the production processes of industries such as chemical, power, and pharmaceutical, large amounts of wastewater with high salt content are generated, often referred to as high-salinity wastewater. High-salinity wastewater is generally defined as wastewater with a total salt content of at least 1% by mass. This type of wastewater contains various substances, including salt, oil, organic heavy metals, and radioactive materials. Ion chromatography, a type of high-performance liquid chromatography, is widely used in the analysis of anions and cations. It achieves ion separation through the principle of ion exchange and is detected by detectors such as conductivity and ultraviolet light. It has advantages such as fast analysis speed, good selectivity, and the ability to simultaneously determine multiple components. However, determining ions in high-salinity wastewater presents several challenges.

[0003] In summary, the inventors have found that existing interference removal devices for ion chromatography detection mainly have the following drawbacks: Because high-salt wastewater contains suspended solids and impurities that interfere with other ions, during ion chromatography detection of high-salt wastewater, these impurities continuously accumulate and adhere to the outside of the chromatographic column used to determine the target ions, along with the flow of the wastewater. This affects the interaction between the stationary phase and the mobile phase inside the column, preventing the column from effectively separating different components in the wastewater and interfering with the measured target ion results, thus significantly increasing the error rate in the chromatographic detection process. Summary of the Invention

[0004] The technical solution adopted by the present invention to achieve the technical objective is: an interference removal device for ion chromatography detection of high-salt wastewater, the structure of which includes: a detection host, a storage tank, a transmission pipe, a base, and a processor. The transmission pipe is connected through the detection host and the storage tank, and both the detection host and the storage tank are fixedly installed on the base. The processor is provided on the outside of the detection host.

[0005] As a further improvement of the present invention, the detection host is provided with a bracket, and there are two brackets, both of which are installed between the fixed frame and the working column. One end of the working column is fixedly installed at the bottom of the cylinder, while the other end of the working column is located at the bottom of the mixing component. The mixing component and the flocculant box are located at the top inside the cylinder.

[0006] As a further improvement of the present invention, the mixing component is also provided with a stirring rod, which is bent and disposed between the blade and the fixing rod. The blade is inclined on one side of the fixing rod, and four blades and fixing rods are arranged around the top disc of the cylinder. The outer side of the blade is slidably fitted to the inner side of the inner ring, and the inner ring is fixedly connected to the top of the filter screen.

[0007] As a further improvement of the present invention, the flocculant box and the mixing component are started simultaneously by means of a processor and a wireless transmission module, which can mix the flocculant and the high-salt wastewater entering from the top of the cylinder. The mixing component divides the internal space of the cylinder into two parts and runs in the same straight line perpendicular to the working column at the bottom, which can better pre-treat the suspended solids and impurities inside the high-salt wastewater.

[0008] As a further improvement of the present invention, the processor contains sensors, a wireless transmission module, etc., and is equipped with a touch panel and a display screen to electrically connect with the detection host and transmit data, and the storage tank can quantitatively transport high-salt wastewater to the detection host through a transmission pipe.

[0009] As a further improvement of the present invention, the top of the cylinder is fixedly connected to the transmission pipe, and the bottom of the cylinder is vertically installed above the base. The flocculant box and the mixing component are started simultaneously through the wireless transmission module to receive the high-salt wastewater transported into the cylinder by the transmission pipe.

[0010] As a further improvement of the present invention, the outer ring and the filter screen are horizontally arranged inside the cylinder, and the inner ring above the filter screen is made of rubber and the surface is rolled up to limit the end movement speed and path of the blade and the fixed rod, and the bottom side edge of the blade is fitted with the filter screen above it.

[0011] As a further improvement of the present invention, the stirring rod is also provided with retaining teeth, which are horizontally and equidistantly positioned above the flexible rod, and one end of the flexible rod is fixedly connected to the mounting plate. As a further improvement of the present invention, the mounting plate is horizontally disposed above the fixed rod, and the flexible rod is bent and installed between the fixed rod and the back of the adjacent blade through the mounting plate, and the groove changes its opening size as the flexible rod deforms.

[0012] As a further improvement of the present invention, the working column is also provided with a chromatographic column, and both the upper and lower ends of the chromatographic column are provided with mounting columns. The outer side of the chromatographic column is provided with a mating interface, and a large quantitative frame with the same shape is fitted on the outer side of the mating interface. An assistive component is provided at the opening of the quantitative frame.

[0013] As a further improvement of the present invention, the chromatographic column and the mounting column are vertically arranged inside the filter screen and the cylinder, and the chromatographic column and the processor on the outside of the cylinder are electrically connected.

[0014] As a further improvement of the present invention, the assisting component is provided with a sleeve, the sleeve is opened in the middle of the filling plate, and a through rod is provided through the inside of the sleeve. Both ends of the through rod are provided with top plates, and an adjusting component is installed at the bottom of the top plate. A centering plate is provided at the bottom of the filling plate.

[0015] As a further improvement of the present invention, the centering plate and the filling plate form an inverted isosceles trapezoidal integrated structure inside the interface and the quantitative frame, and are vertically sleeved inside the interface and the quantitative frame. The through rod and the sleeve are both curved structures, and the through rod and the top plate slide left and right inside the quantitative frame.

[0016] As a further improvement of the present invention, the adjusting member is also provided with a folding page, which is installed on the side of the slide plate. Both the folding page and the slide plate are slidably installed on the side of the side wing. There are two side wings, both of which are fixedly connected to the outside of the center plate. A hook is provided at the top opening of the center plate.

[0017] As a further improvement of the present invention, the folding page is a foldable structure with rubber material at the end, and is fitted with the slide plate at a gap to the side of the filling plate, and the hook is hinged to the bottom of the top plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through further improvements to the detection host, uses a mixing component and a working column vertically installed inside the cylinder. This allows high-salt wastewater, quantitatively delivered into the cylinder via a transfer pipe, to undergo pretreatment using a flocculant box and mixing component to remove interference from suspended solids and impurities. This pretreatment causes the suspended solids and impurities to precipitate as flocculated particles on the inner wall of the cylinder. The filtered high-salt wastewater is then slowly transferred to the working column for chromatographic detection. This enhances the interaction between the stationary and mobile phases within the column, promoting effective separation of different components in the wastewater and facilitating the determination of target ions. Real-time data is displayed on a screen via the processor's wireless transmission module, ensuring the device's effectiveness in removing interference during ion chromatography detection of high-salt wastewater.

[0019] 2. With further improvements to the mixing component, this invention utilizes a stirring rod and a filter screen within the mixing component to allow high-salt wastewater and the flocculant released from the flocculant box to mix together under the combined action of the paddle and the fixing rod. This allows suspended solids and impurities in the wastewater to form flocculent particles with the flocculant, which are then dispersed, aggregated, and precipitated to the outside of the filter screen as the paddle and fixing rod rotate, thus better interfering with and removing factors in the high-salt wastewater that affect the determination of target ions.

[0020] 3. With the further improvement of the working column, the present invention contains an assisting component inside the working column. When the high-salt wastewater filtered to the bottom of the cylinder reaches a certain height, it will slowly and quantitatively flow from the opening of the quantitative frame to the interface and the interior of the chromatographic column with the help of the intermittent movement of the assisting component, which is beneficial to the accurate determination of the target ion by the chromatographic column.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 4 As shown: This invention provides an interference removal device for ion chromatography detection of high-salt wastewater. Its structure includes: a detection host 1, a storage tank 2, a transmission pipe 3, a base 4, and a processor 5. The transmission pipe 3 is connected through the detection host 1 and the storage tank 2, and both the detection host 1 and the storage tank 2 are fixedly installed on the base 4. The processor 5 is provided on the outside of the detection host 1.

[0030] The detection host 1 is provided with a bracket 11. There are two brackets 11, both of which are installed between the fixed frame 15 and the working column 16. One end of the working column 16 is fixedly installed at the bottom of the cylinder 14, and the other end of the working column 16 is located at the bottom of the mixing component 13. The mixing component 13 and the flocculant box 12 are located at the top of the inner side of the cylinder 14.

[0031] The mixing component 13 is further provided with a stirring rod 131, which is bent and disposed between the blade 135 and the fixing rod 136. The blade 135 is inclined on one side of the fixing rod 136. There are four blades 135 and fixing rods 136 surrounding the top disc of the cylinder 14. The outer side of the blade 135 is slidably engaged with the inner side of the inner ring 134. The inner ring 134 is fixedly connected to the top of the filter screen 132.

[0032] The flocculant box 12 and the mixing component 13 are started simultaneously with the help of the processor 5 and the wireless transmission module. The flocculant and the high-salt wastewater entering from the top of the cylinder 14 can be mixed. The mixing component 13 divides the internal space of the cylinder 14 into two parts and runs vertically in the same straight line as the working column 16 at the bottom, which can better pre-treat the suspended solids and impurities inside the high-salt wastewater.

[0033] The processor 5 contains sensors, a wireless transmission module, etc., and is equipped with a touch panel and a display screen to electrically connect with the detection host 1 and transmit data. The storage tank 2 can quantitatively transport high-salt wastewater to the detection host 1 through the transmission pipe 3.

[0034] The top of the cylinder 14 is fixedly connected to the transmission pipe 3, and the bottom of the cylinder 14 is vertically installed above the base 4. The flocculant box 12 and the mixing component 13 are started simultaneously through the wireless transmission module to receive the high-salt wastewater transported into the cylinder 14 by the transmission pipe 3.

[0035] The outer ring 133 and the filter screen 132 are horizontally arranged inside the cylinder 14, while the inner ring 134 above the filter screen 132 is made of rubber and has a rolled-up surface, which restricts the end movement speed and path of the blade 135 and the fixing rod 136, and the bottom side edge of the blade 135 is fitted with the filter screen 132 above it.

[0036] The stirring rod 131 is also provided with a retaining tooth 1311. The retaining tooth 1311 and the groove 1312 are horizontally and equidistantly arranged above the soft rod 1314, and one end of the soft rod 1314 is fixedly connected to the mounting plate 1313.

[0037] The mounting plate 1313 is horizontally positioned above the fixed rod 136, and the flexible rod 1314 is bent and mounted between the fixed rod 136 and the back of the adjacent blade 135 via the mounting plate 1313. The groove 1312 changes its opening size as the flexible rod 1314 deforms.

[0038] The specific functions and operation procedures of this embodiment are as follows: In this invention, inputting specified data into the touch panel of the processor 5 activates the storage tank 2, which quantitatively delivers the wastewater stored in the storage tank 2 to the detection host 1 via the transmission pipe 3. This allows the high-salt wastewater to enter the upper part of the cylinder 14. Simultaneously, the sensors and wireless transmission module of the processor 5 control the flocculant box 12 to release flocculant into the high-salt wastewater. The disc inside the cylinder 14 then rotates the paddles 135 and the fixed rod 136 in a directional and uniform manner. This allows suspended solids and impurities in the high-salt wastewater to begin mixing with the flocculant through centrifugal force, resulting in flocculated particles that settle. These particles then flow downwards along the inclined paddles 135 and the fixed rod 136, causing the flocculated particles to surge in the same direction between the fixed rod 136 and the adjacent paddles 135, where they are fixed by the mounting plate 1313. The bends in the installed flexible rod 1314 allow the flocculants to further alter the degree of bending of the rod 1314. The pushing action of the flexible rod 1314 causes the teeth 1311 and grooves 1312 on its outer side to change size, better widening the gaps between the teeth 1311. This allows the flocculants received by the flexible rod 1314 to centrifugally roll along its bending direction and efficiently aggregate onto the filter screen 132 on the outer side of the inner ring 134. The filtered high-salt wastewater is dispersed onto the filter screen 132 by the centrifugal force of the paddle 135 and the fixed rod 136, and then filtered downwards, dripping more purely to the bottom of the cylinder 14. This prevents suspended solids and impurities in the high-salt wastewater from continuously accumulating and adhering to the inside of the detection unit 1, thus affecting the determination of target ions in the next process.

[0039] Example 2: Figures 5 to 7 As shown: This invention provides an interference removal device for ion chromatography detection of high-salt wastewater. Its structure includes a working column 16 and a chromatographic column 161. The chromatographic column 161 has mounting columns 162 at both the upper and lower ends. The chromatographic column 161 has a docking interface 163 on the outside. A quantitative frame 164 with the same shape and larger size is fitted on the outside of the docking interface 163. An assistive component 165 is provided at the opening of the quantitative frame 164.

[0040] The chromatographic column 161 and the mounting column 162 are vertically arranged inside the filter screen 132 and the cylinder 14, and the chromatographic column 161 is electrically connected to the processor 5 on the outside of the cylinder 14.

[0041] The assisting component 165 includes a sleeve 1651, which is located in the middle of the filling plate 1654. A through rod 1655 extends through the sleeve 1651, and top plates 1652 are provided at both ends of the through rod 1655. An adjusting component 1656 is installed at the bottom of the top plate 1652. A centering plate 1653 is provided at the bottom of the filling plate 1654. The centering plate 1653 and the filling plate 1654 form an inverted isosceles trapezoidal integrated structure inside the interface 163 and the quantitative frame 164, and are vertically sleeved inside the interface 163 and the quantitative frame 164. The through rod 1655 and the sleeve 1651 are both curved structures, and the through rod 1655 and the top plate 1652 slide left and right on the inside of the quantitative frame 164.

[0042] The adjusting component 1656 also includes a folding flap 6561, which is mounted on the side of the slide plate 6563. Both the folding flap 6561 and the slide plate 6563 are slidably mounted on the side of the side wing 6562. There are two side wings 6562, both of which are fixedly connected to the outside of the center plate 6565. A hook 6564 is provided at the top opening of the center plate 6565. The folding page 6561 is a foldable structure with rubber end material, and is fitted with the slide plate 6563 at a gap to the side of the filling plate 1654. The hook 6564 is hinged to the bottom of the top plate 1652.

[0043] The specific functions and operation procedures of this embodiment are as follows: In this invention, when the filtered high-salt wastewater dripping from the bottom of the cylinder 14 reaches a certain height, the processor 5 will first activate the chromatographic column 161 between the mounting columns 162. The high-salt wastewater is received via the interface 163 and the metering frame 164. Before the high-salt wastewater flows into the metering frame 164, pressure is applied to the packing plate 1654, causing the inverted isosceles trapezoidal structure formed by the packing plate 1654 and the centering plate 1653 to press in the same direction towards the interface 163. This causes the through rod 1655 inside the sleeve 1651 located in the middle of the packing plate 1654 and the centering plate 1653 to drive the top plate 1652 at its end to press against the inner wall of the metering frame 164. This causes the hook 6564 hinged at the annular position of the top plate 1652 to clamp the center plate 6565 in a specific orientation, gradually opening the outer wings 6562 of the center plate 6565 and allowing the folding pages to... The rubber material at the end of 6561 can press against the inclined side of the filling plate 1654, thereby causing the folding page 6561 and the sliding plate 6563 to unfold outward and support the tip of the side wing 6562 on the inclined side of the filling plate 1654 in a three-point manner. This can act as a limiting condition to prevent the through rod 1655 from bending and extending further, allowing the through rod 1655 to reciprocate inside the sleeve 1651. This causes the inverted isosceles trapezoidal structure formed by the filling plate 1654 and the center plate 1653 to slide back and forth continuously within the interface 163. Consequently, the high-salt wastewater is drawn into the chromatographic column 161 for detection in an equal and slow manner, and the target standard ion is accurately determined. The real-time data is then displayed on the screen with the help of the wireless transmission module and sensor of the processor 5, ensuring the device's interference removal effect on the ion chromatography detection of high-salt wastewater.

[0044] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
