Description

Technical Field

[0001] This invention relates to sample pretreatment technology, specifically to an acidification blowing device for reducing chloride ion concentration in high-chlorine surface water. Background Technology

[0002] The acidification aeration device for reducing chloride ion concentration in high-chloride surface water is a key piece of equipment specifically designed for pretreatment of high-chloride surface water for chemical oxygen demand (COD) measurement. This device removes chloride ions by introducing an inert gas, such as nitrogen, into the acidified water sample, thus eliminating the interference of high chloride concentrations on subsequent COD measurements. In applications such as environmental monitoring, water quality analysis, and water treatment engineering, this type of pretreatment device plays an irreplaceable role in ensuring the accuracy of COD test results.

[0003] Existing blowing devices typically place the storage bottle directly inside a water bath heating mechanism. By heating the water bath medium, the water sample inside the storage bottle is indirectly heated to promote the volatilization of hydrogen chloride gas. During the heating process, the water bath medium boils and generates a large number of bubbles. These bubbles rise and impact the bottom of the storage bottle, easily causing it to shake or even tip over. If the device lacks a positioning or stabilizing structure, the storage bottle is difficult to keep vertical and fixed during blowing. However, the shaking of the storage bottle can interfere with the stable insertion of the ventilation pipe, potentially leading to uneven nitrogen distribution and affecting the blowing efficiency. Bottle displacement may also cause the cap seal to fail, resulting in the leakage of corrosive hydrogen chloride gas, which not only contaminates the experimental environment but also poses a safety risk.

[0004] Therefore, the applicant proposes an acidification blowing device to reduce the chloride ion concentration in high-chlorine surface water in order to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an acidification aeration device for reducing the chloride ion concentration in high-chloride surface water, in order to solve the problems of existing aeration devices that place the storage bottle in a water bath for heating, causing the bubbles generated by boiling to impact the bottom of the bottle, which can easily lead to the storage bottle shaking or tipping over; and without a fixed structure, it can cause the vent pipe to deviate, nitrogen gas to be unevenly distributed, and the seal to fail, resulting in hydrogen chloride leakage, which affects the treatment efficiency and brings safety risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an acidification blowing device for reducing chloride ion concentration in high-chloride surface water, comprising a shell, a heating mechanism disposed below the shell, the heating mechanism including an insulating plate, a resistance wire heating body fixedly connected above the insulating plate, the top of the resistance wire heating body abutting against the bottom of the shell, a processing mechanism disposed within the inner cavity of the shell, the processing mechanism including a liquid storage bottle, a bottle cap disposed above the liquid storage bottle, and a venting pipe disposed at the top of the bottle cap, a nitrogen flow meter fixedly connected to one end of the venting pipe, and the other end of the venting pipe extending through the top of the bottle cap to the inner cavity of the liquid storage bottle, an acid adding pipe and a gas guiding component fixedly connected to both sides of the bottle cap, a plug being engaged at one end of the acid adding pipe, a waste gas treatment bottle disposed on one side of the shell, a waste gas pipe disposed within the inner cavity of the waste gas treatment bottle, and a waste gas pipe fixedly connected at one end to one end of the gas guiding component;

[0007] An adapter mechanism is provided on the other side of the outer shell. The adapter mechanism includes a mounting frame. One end of the mounting frame extends through the side wall of the outer shell into the inner cavity of the outer shell. Two sliding plates are slidably connected to the inner cavity of the mounting frame. Vertical rods are fixedly connected to both sides of the sliding plates, and a horizontal plate is fixedly connected to one side of the vertical rods. A cylinder is provided between the two corresponding horizontal plates. Force blocks are fixedly connected to both sides of the mounting frame, and a tension spring is fixedly connected to one side of the force block. One end of the tension spring is fixedly connected to one side of the outer shell.

[0008] Furthermore, the inner cavity of the acid addition tube and the inner cavity of the gas guide are both connected to the inner cavity of the bottle cap.

[0009] Furthermore, short rods are fixedly connected to the four corners of the top of the insulating plate, and one end of each short rod is fixedly connected to the bottom of the outer shell.

[0010] Furthermore, the two ends of the cylinder are respectively rotatably connected to one side of the corresponding horizontal plate via a pivot.

[0011] Furthermore, sliding blocks are fixedly connected to both sides of the skateboard, and sliding grooves adapted to the sliding blocks are respectively opened on the inner walls of both sides of the mounting frame.

[0012] Furthermore, an outer frame is fixedly connected to one side of the skateboard, and a plurality of insertion holes are provided on the inner wall of one side of the mounting frame along the horizontal direction of the mounting frame. A fixing block is slidably connected to the inner cavity of the outer frame, and an insertion rod is fixedly connected to one side of the fixing block. One end of the insertion rod passes through the side wall of the outer frame and is inserted into the inner cavity of the corresponding insertion hole.

[0013] Furthermore, through grooves are respectively opened on the top two sides of the fixing block, and a limiting rod is horizontally arranged in the inner cavity of the through groove. Limiting grooves are respectively opened on both sides of the inner wall of the outer frame, and one side of the limiting rod is in contact with the inner wall of the corresponding limiting groove.

[0014] Furthermore, the two sides of the limiting rod are rotatably connected to the inner wall of the adjacent through groove via a torsion spring shaft.

[0015] Furthermore, a connecting mechanism is provided on one side of the inner cavity of the outer shell. The connecting mechanism includes a horizontal frame. Several spring dampers are fixedly connected to the inner wall of one side of the horizontal frame and along the horizontal direction of the horizontal frame. A connecting seat is fixedly connected to one side of the spring damper. A fitting column is provided in the inner cavity of the connecting seat.

[0016] Furthermore, the two ends of the fitting column are respectively rotatably connected to the inner wall of the corresponding connecting seat via a rotating shaft.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This solution utilizes the cooperation of the adapter and connection mechanisms to create a multi-point flexible clamping effect on the storage bottle. Even under internal disturbances caused by heating or nitrogen bubbling, it can suppress shaking, displacement, or tipping, ensuring the bottle remains vertical and fixed throughout the entire treatment process. This ensures that the ventilation pipe is always at the designed insertion depth and angle, allowing nitrogen to be evenly distributed at the bottom of the water sample, improving hydrogen chloride stripping efficiency and chloride ion removal rate, thereby enhancing the accuracy of chemical oxygen demand (COD) measurement. Simultaneously, the bottle cap maintains a good seal due to no displacement, the acid addition tube is reliably sealed by the plug, and the gas guide and exhaust pipe form a closed exhaust path. Multiple seals prevent leakage of hydrogen chloride gas, ensuring personnel safety and avoiding environmental pollution. Furthermore, the insertion and connection of the rod and hole in the adapter mechanism, as well as the guiding structure of the limiting rod and limiting groove, support flexible adjustment and stable locking of storage bottles of different sizes, improving the versatility and ease of operation of the device.

[0019] Through the adaptation mechanism, the liquid storage bottle obtains reliable and stable support during processing: the mounting frame extends into the inner cavity of the outer shell, and the sliding plate inside it drives the cylinder to fit against the outer wall of the liquid storage bottle through the vertical rod and horizontal plate. With the elastic return action of the tension spring, it can absorb the disturbance caused by heating or nitrogen bubbling, preventing the bottle from shaking or tipping over. At the same time, there is a sliding fixing block in the outer frame outside the sliding plate. The insertion rod on it can be inserted into the insertion hole at different positions on the side wall of the mounting frame, realizing flexible adjustment and firm locking of the clamping width for liquid storage bottles of different sizes. The cooperation between the limiting rod and the limiting groove further ensures that the adjustment process is smooth and precise. Thus, not only is the stable insertion and sealing reliability of the venting pipe guaranteed, but also the ease of operation and the versatility of the device are improved.

[0020] Through the connection mechanism, the liquid storage bottle receives contralateral buffer support during the acidification and blowing process: the horizontal frame is fixed to one side of the inner cavity of the outer shell, and multiple spring dampers arranged horizontally inside push the connecting seat to apply flexible pressure towards the liquid storage bottle, so that the fitting column fits tightly against the outer wall of the bottle; the fitting column is rotatably connected to the connecting seat through a rotating shaft, which can adapt to the curved contour of the liquid storage bottle, providing stable support while avoiding damage caused by rigid contact; this structure and the adapter mechanism form a left-right cooperative clamping, suppressing shaking, displacement or even overturning caused by heating or nitrogen bubbling, ensuring that the bottle always remains in a vertical and fixed state, thereby ensuring the insertion stability of the ventilation pipe, the sealing reliability of the bottle cap and the safe and efficient operation of the overall pretreatment process.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] As attached Figure 1 To be continued Figure 7 As shown:

[0033] Example 1:

[0034] This invention provides an acidification aeration device for reducing chloride ion concentration in high-chloride surface water. The device includes a housing 1, a heating mechanism 2 located below the housing 1, the heating mechanism 2 comprising an insulating plate 201, a resistance wire heating body 202 fixedly connected above the insulating plate 201, the top of the resistance wire heating body 202 abutting against the bottom of the housing 1, and a processing mechanism 3 located within the inner cavity of the housing 1. The processing mechanism 3 includes a storage bottle 301, and a bottle cap 302 is located above the storage bottle 301, with a ventilation pipe located on the top of the bottle cap 302. 305, one end of the ventilation pipe 305 is fixedly connected to a nitrogen flow meter 306, and the other end of the ventilation pipe 305 extends through the top of the bottle cap 302 to the inner cavity of the liquid storage bottle 301. The two sides of the bottle cap 302 are respectively fixedly connected to an acid adding pipe 303 and a gas guide 307. One end of the acid adding pipe 303 is snapped with a plug 304. A waste gas treatment bottle 309 is provided on one side of the outer shell 1, and a waste gas pipe 308 is provided in the inner cavity of the waste gas treatment bottle 309. One end of the waste gas pipe 308 is fixedly connected to one end of the gas guide 307.

[0035] An adapter mechanism 4 is provided on the other side of the outer shell 1. The adapter mechanism 4 includes a mounting frame 401. One end of the mounting frame 401 extends through the side wall of the outer shell 1 into the inner cavity of the outer shell 1. Two sliding plates 404 are slidably connected to the inner cavity of the mounting frame 401. Vertical rods 405 are fixedly connected to both sides of the sliding plates 404, and a horizontal plate 406 is fixedly connected to one side of the vertical rods 405. A cylinder 407 is provided between the two corresponding horizontal plates 406. Force blocks 402 are fixedly connected to both sides of the mounting frame 401, and a tension spring 403 is fixedly connected to one side of the force block 402. One end of the tension spring 403 is fixedly connected to one side of the outer shell 1.

[0036] The inner cavity of the acid addition tube 303 and the inner cavity of the gas guide 307 are both connected to the inner cavity of the bottle cap 302.

[0037] Working principle: First, personnel inject the high-chlorine surface water to be treated into the storage bottle 301 in the treatment mechanism 3 and tighten the sealing cap 302. Then, an appropriate amount of concentrated sulfuric acid is added to the storage bottle 301 through the acid-adding tube 303 located on one side of the cap 302 to acidify the water sample, causing chloride ions to convert into hydrogen chloride gas. After acid addition, the stopper 304 is secured to the end of the acid-adding tube 303 to ensure a tight seal. Next, the heating mechanism 2 located below the outer casing 1 is activated. The resistance wire heating body 202 is energized and heats up. The heat is conducted to the inner cavity of the outer casing 1 through the contact surface that abuts against the bottom of the outer casing 1, indirectly heating the storage bottle 301 to promote the release of hydrogen chloride gas. The insulating plate 201 provides electrical isolation for the resistance wire heating body 202. The short rod 2... 03. The insulating plate 201 is securely connected to the bottom of the outer shell 1 to ensure the overall stability of the heating structure. Simultaneously, the nitrogen source, after its flow rate is precisely controlled by the nitrogen flow meter 306, enters the system through the ventilation pipe 305. One end of the ventilation pipe 305 is connected to the nitrogen flow meter 306, and the other end passes through the top of the bottle cap 302 and extends to the bottom of the inner cavity of the liquid storage bottle 301, thus uniformly introducing nitrogen into the water sample in a bubbling manner, carrying the generated hydrogen chloride gas to the surface of the liquid. The generated hydrogen chloride-containing waste gas is discharged through the gas guide 307 on the other side of the bottle cap 302 and sealed through the waste gas pipe 308 fixedly connected to it to the waste gas treatment bottle 309 located on one side of the outer shell 1, where it is neutralized by the alkaline absorbent liquid, achieving harmless emission of the exhaust gas. During the heating and blowing process, the liquid storage bottle 301 is stably clamped in a multi-point support system composed of the adapter mechanism 4 and the connecting mechanism 5. One end of the mounting frame 401 of the adapter mechanism 4 extends through the side wall of the outer shell 1 into the inner cavity. Two sliding plates 404 are slidably connected inside. The sides of the sliding plates 404 are connected to horizontal plates 406 via vertical rods 405. A cylinder 407 is positioned between the two horizontal plates 406, forming a flexible support against the outer wall of the liquid storage bottle 301. When the liquid storage bottle 301 tends to shake due to thermal disturbance or airflow impact, the force block 402 drives the tension spring 403 to generate a rebound force, which drives the sliding plates 404 and their connected structures to automatically adjust their position and apply a reverse constraint force to the liquid storage bottle 301, suppressing displacement. Simultaneously, an outer... The frame 409 has a fixed block 410 that is slidably installed inside it. The insertion rod 411 on the fixed block 410 can be inserted into the insertion hole 408 at the corresponding height on the side wall of the mounting frame 401 to lock the horizontal position of the slide plate 404. This, together with the sliding guide of the limiting rod 412 in the limiting groove 413, ensures that the clamping structure remains stable after adjustment. In addition, a connecting mechanism 5 is provided on the other side of the inner cavity of the outer shell 1. Multiple spring dampers 502 are fixed horizontally inside its cross frame 501. The spring dampers 502 push the connecting seat 503 and the fitting column 504 rotatably connected therein to press against the opposite outer wall of the liquid storage bottle 301, forming a symmetrical buffer support, which further enhances the overall stability and prevents the liquid storage bottle 301 from shaking, shifting or even tipping over during heating and blowing.

[0038] This solution employs a dry heating mechanism 2, consisting of a resistance wire heating body 202, an insulating plate 201, and a short rod 203, replacing the traditional water bath heating method. This avoids external disturbances caused by bubbles generated during the boiling of the water bath medium impacting the bottom of the storage bottle 301. More importantly, by setting an adapter mechanism 4 and a connecting mechanism 5 inside the outer shell 1, even under internal disturbances caused by heating or nitrogen bubbling, the shaking, displacement, or tipping of the storage bottle 301 can be suppressed, ensuring that it remains vertical and fixed throughout the entire treatment process. The stable positioning of the storage bottle 301 ensures that the venting pipe 305 is always at the designed insertion depth and angle, allowing nitrogen to be evenly distributed in the water sample. At the bottom, the efficiency of hydrogen chloride stripping and chloride ion removal are improved, thereby increasing the accuracy of subsequent chemical oxygen demand (COD) determination. In addition, the cap 302 maintains a good seal because the bottle body does not shift, the acid addition tube 303 is reliably sealed by the plug 304, and the gas guide 307 and the exhaust pipe 308 form a closed exhaust passage. Multiple sealing measures prevent the leakage of corrosive gases containing hydrogen chloride, protecting the health of laboratory personnel and avoiding environmental pollution. The cooperation between the insertion rod 411 and the insertion hole 408 in the adapter mechanism 4, as well as the guiding structure of the limiting rod 412 and the limiting groove 413, allow the device to flexibly adjust the clamping width and reliably lock according to different specifications of storage bottles 301, improving versatility and ease of operation.

[0039] Example 2:

[0040] This embodiment is basically the same as the previous embodiment, except that short rods 203 are fixedly connected to the four corners of the top of the insulating plate 201, and one end of the short rods 203 is fixedly connected to the bottom of the outer shell 1.

[0041] The two ends of the cylinder 407 are rotatably connected to one side of the corresponding horizontal plate 406 via a rotating shaft.

[0042] Sliding blocks are fixedly connected to both sides of the slide plate 404, and sliding grooves that are adapted to the sliding blocks are respectively opened on the inner walls of both sides of the mounting frame 401.

[0043] A frame 409 is fixedly connected to one side of the slide plate 404. A number of insertion holes 408 are provided on the inner wall of one side of the mounting frame 401 along the horizontal direction of the mounting frame 401. A fixing block 410 is slidably connected to the inner cavity of the outer frame 409. A plug rod 411 is fixedly connected to one side of the fixing block 410. One end of the plug rod 411 passes through the side wall of the outer frame 409 and is inserted into the inner cavity of the corresponding insertion hole 408.

[0044] Working principle: With the inner cavities of the acid addition tube 303 and the gas guide 307 both connected to the inner cavity of the bottle cap 302, acid can be smoothly injected into the storage bottle 301, and the hydrogen chloride gas generated in the reaction can be smoothly discharged through the gas guide 307. This ensures unobstructed acid addition and exhaust channels, improving pretreatment efficiency. Short rods 203 are fixedly connected to the four corners of the top of the insulating plate 201, with one end of each rod fixedly connected to the bottom of the outer shell 1. The heat generated by the resistance wire heating body 202 is stably conducted to the outer shell 1, while the insulating plate 201 is firmly positioned, enhancing the structural stability and electrical safety of the heating mechanism 2. The cylindrical 407 is rotatably connected to one side of the corresponding horizontal plate 406 at both ends via a rotating shaft. The cylindrical 407 can rotate adaptively with the outer contour of the liquid storage bottle 301, avoiding rigid friction. This achieves the effect of protecting the glassware and extending the service life of the device while maintaining stable clamping. Sliding blocks are fixedly connected to both sides of the sliding plate 404. Sliding grooves that match the sliding blocks are opened on the inner walls of both sides of the mounting frame 401. The sliding plate 404 slides smoothly along the mounting frame 401, causing the cylindrical 407 to apply a uniform clamping force to the liquid storage bottle 301. This improves the stability of the movement and the reliability of the clamping mechanism 4.

[0045] Example 3:

[0046] This embodiment is basically the same as the previous embodiment, except that through grooves are provided on both sides of the top of the fixing block 410, and a limiting rod 412 is horizontally provided in the inner cavity of the through groove. Limiting grooves 413 are provided on both sides of the inner wall of the outer frame 409, and one side of the limiting rod 412 is in contact with the inner wall of the corresponding limiting groove 413.

[0047] The two sides of the limiting rod 412 are rotatably connected to the inner wall of the adjacent through groove via torsion spring shafts.

[0048] A connecting mechanism 5 is provided on one side of the inner cavity of the outer shell 1. The connecting mechanism 5 includes a horizontal frame 501. Several spring dampers 502 are fixedly connected to the inner wall of one side of the horizontal frame 501 and along the horizontal direction of the horizontal frame 501. A connecting seat 503 is fixedly connected to one side of the spring damper 502. A fitting column 504 is provided in the inner cavity of the connecting seat 503.

[0049] The two ends of the fitting column 504 are rotatably connected to the inner wall of the corresponding connecting seat 503 via a rotating shaft.

[0050] Working principle: An outer frame 409 is fixedly connected to one side of the sliding plate 404. Several insertion holes 408 are formed on the inner wall of one side of the mounting frame 401 along the horizontal direction of the mounting frame 401. A fixing block 410 is slidably connected to the inner cavity of the outer frame 409, and an insertion rod 411 is fixedly connected to one side of the fixing block 410. One end of the insertion rod 411 passes through the side wall of the outer frame 409 and is inserted into the inner cavity of the corresponding insertion hole 408. This configuration allows the position of the sliding plate 404 to be adjusted and locked according to the diameter of the liquid storage bottle 301, achieving both flexible adjustment of the clamping width and reliable fixation. Through slots are formed on both sides of the top of the fixing block 410, and the inner cavity of the through slots is horizontally positioned. A limiting rod 412 is provided, and limiting grooves 413 are respectively opened on both sides of the inner wall of the outer frame 409. One side of the limiting rod 412 is fitted with the inner wall of the corresponding limiting groove 413. The limiting rod 412 slides along the limiting groove 413 to guide the movement direction of the fixing block 410, thereby preventing the insertion rod 411 from deviating and ensuring its accurate insertion into the insertion hole 408. The limiting rod 412 is rotatably connected to the inner wall of the adjacent through groove through a torsion spring shaft on both sides. The limiting rod 412 can rotate slightly during insertion or removal to adapt to assembly errors, and automatically resets to fit the limiting groove 413 after being in place, thereby improving the smoothness of operation and positioning accuracy.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
