Description

Technical Field

[0001] This invention relates to the field of TOC analyzer technology, specifically a portable TOC analyzer with an internal cleaning structure. Background Technology

[0002] A TOC analyzer, also known as a total organic carbon analyzer, uses TOC to represent the total amount of organic matter. It utilizes the complete combustion reaction of organic matter, which generates carbon dioxide gas through complete gasification and combustion. Infrared analysis instruments are then used to accurately measure the total amount of carbon dioxide generated during the combustion reaction, thus calculating the total organic carbon content. Based on this principle, the total amount of organic carbon in a substance can be accurately measured. Therefore, the use of a TOC analyzer can serve as an important reference indicator for detecting and evaluating the degree of organic pollution in water bodies.

[0003] Existing TOC analyzers, when analyzing and detecting organic pollution in water bodies, require the use of combustion reactions to measure the amount of carbon dioxide generated, thus determining the total carbon content of organic pollutants. This requires complete combustion during the analysis and detection process. During combustion, pollutants form byproducts such as residues and adhesions on the combustion chamber walls, which can affect subsequent organic pollution detection values. To avoid the influence of combustion byproducts on subsequent organic pollution detection values, manual cleaning and drying of the combustion chamber is required after each combustion reaction and total organic carbon detection. This cleaning process is inefficient and prone to errors in subsequent organic pollution detection and analysis values ​​due to carelessness and inefficiency in manual cleaning.

[0004] Furthermore, manual operations such as removing, cleaning, and reinstalling the combustion chamber not only affect the efficiency of equipment analysis and testing, but also result in poor safety and equipment protection, making the equipment unsuitable for large-scale organic pollution detection and analysis applications.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on existing portable TOC analyzers. Summary of the Invention

[0006] The purpose of this invention is to provide a portable TOC analyzer with an internal cleaning structure to solve the problem mentioned in the background art that existing portable TOC analyzers have low efficiency in repeatedly cleaning and drying the combustion chamber after a single combustion reaction and detection of total organic carbon, which cannot meet the needs of batch organic pollution detection and analysis applications.

At the same time, a motor is fixed on the outer wall of the adjusting support, and a bevel gear that meshes with each other is installed between the output shaft of the motor and the central shaft of the take-up roller.

[0014] Preferably, a reset cavity is fixed on the side of the adjusting support away from the winding roller. A reset wheel is rotatably installed inside the reset cavity via a rotating shaft and bearing. An elastic element is also provided between the reset wheel and the reset cavity. At the same time, a reset cable is connected between the reset wheel and the slider.

[0015] Preferably, the reset cable is provided in a one-to-one correspondence with the winding cable and the reset wheel, and the reset cable is slidably connected to the reset cavity through the cable, and the reset cable is wound around the outside of the reset wheel.

[0016] Preferably, the cleaning and sewage discharge component includes a cleaning cavity installed through the right outer wall of the outer casing, and a positioning shell is provided on the side of the cleaning cavity facing the inside of the outer casing. A hydraulic propulsion assembly is provided between the positioning shell and the cleaning cavity, and a cleaning turntable is rotatably installed in the middle of the positioning shell via a bearing. The cleaning turntable is coaxially distributed with the combustion chamber laterally, and the diameter of the cleaning turntable is equal to the inner diameter of the port of the combustion chamber. A sealing ring is provided on the outer side of the connection between the cleaning turntable and the inner wall of the port of the combustion chamber.

[0017] Preferably, a guide pipe is coaxially fixed to the back of the cleaning turntable, and an outer pipe is fixed through the middle of the interior of the cleaning cavity. The guide pipe, the cleaning cavity and the outer pipe form a fitted through-type telescopic structure, and turbine blades are provided inside the guide pipe.

[0018] A flow pipe is fixedly connected to the end of the guide pipe and the cleaning turntable. The opening of the flow pipe is located on the front of the cleaning turntable, and a return water hole is provided through the cleaning turntable. One end of the sewage pipe is connected through the positioning housing, and the other end of the sewage pipe passes through the sewage pipe connected to the outside of the cleaning chamber.

A storage cavity is also embedded in the front of the cleaning turntable. One end of a fastening cable is connected to the storage cavity through an elastic element.

[0020] Preferably, the opening of the flow tube is located on the side of the hinge between the cleaning turntable and the folding brush, and the end of the flow tube is magnetically set for the adsorption and positioning of the folding brush.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the portable TOC analyzer with an internal cleaning structure facilitates the detection and analysis of the total carbon content in a complete combustion reaction, and allows for rapid internal cleaning and drying after the combustion reaction is completed, along with simultaneous wastewater discharge. The operation is safe and quick. The specific details are as follows:

[0022] 1. By using the angle adjustment mechanism, the rotational installation of the combustion chamber and the base is achieved through the rotational connection of the shaft. The motor starts and the meshing connection between the bevel teeth realizes the forward and reverse rotation of the winding roller. When the winding roller rotates, the guide roller guides the winding cable, and the slider and the adjustable support set in the inner cavity engage and slide to realize the sliding of the slider when the winding cable is wound. This drives the angle deflection between the combustion chamber and the base to change. The vertical state of the combustion chamber can be assembled and positioned with the top cover plate to carry out the complete combustion reaction of organic matter and the total carbon detection and analysis calculation. The horizontal parallel setting of the combustion chamber, with its port facing the cleaning and sewage discharge component, can achieve efficient cleaning of combustion residue by-products inside the combustion chamber and dry and clean treatment after cleaning and sewage discharge under the assembly and positioning of the cleaning and sewage discharge component and the combustion chamber.

[0023] 2. The combination of the positioning housing and the cleaning turntable allows them to directly fit into the port of the combustion chamber under the action of the hydraulic components, and the fitting port is sealed and isolated. Utilizing the coaxial connection between the guide pipe and the external pipe, external water flow and drying heating gas can be introduced into the guide pipe. The kinetic energy of the liquid flow achieves the rotation of the cleaning turntable through the turbine blades, and the water flow in the guide pipe is discharged through the flow pipe. The impulse kinetic energy of the water flow and the centrifugal force of the rotating cleaning turntable cause the folding brush and connector brush on the cleaning turntable to unfold. Under the action of rotation, the inner wall of the combustion chamber is flushed and cleaned. The wastewater produced by cleaning can be discharged through the return water hole and the drain pipe. Meanwhile, the hot air flow is introduced into the guide pipe, and the kinetic energy of the air flow can also drive the cleaning turntable to rotate, using the air flow to perform drying treatment inside the combustion chamber.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1-5 This invention provides a technical solution: a portable TOC analyzer with an internal cleaning structure, comprising:

[0039] The outer casing 1 has an analyzer body 2 fixed inside and above, and a top cover plate 3 is connected to the bottom outer wall of the analyzer body 2 via a hydraulic assembly. One end of the gas guide pipe 5 is connected through the top cover plate 3, and the other end of the gas guide pipe 5 is connected to the oxygen supplementation assembly 4 inside the outer casing 1.

[0040] It also includes: a base 6, which is fixed inside the outer shell 1, and a combustion chamber 7 is movably mounted on the base 6 via a rotating shaft. The combustion chamber 7 is located directly below the top cover plate 3. When the combustion chamber 7 is in a vertical position, the top cover plate 3 can be directly pushed up and down by the hydraulic components. After the top cover plate 3 and the port of the combustion chamber 7 are assembled and positioned, the oxygen supplementation component 4 and the combustion components on the top cover plate 3 can achieve complete combustion of the substance to be detected and analyzed in the combustion chamber 7. Under the action of complete combustion, carbon dioxide gas is produced, and the carbon content of the carbon dioxide gas is analyzed by the analyzer body 2 to obtain the total carbon pollution of organic matter.

[0041] Example 2: Please refer to Figure 3 and Figures 6-9 As shown, the present invention also provides an angle adjustment mechanism, specifically: the base 6 is also provided with an angle adjustment mechanism for the combustion chamber 7, which is used to change the positioning state of the combustion chamber 7 and adjust the orientation angle of the port of the combustion chamber 7;

[0042] The bottom of the combustion chamber 7 is designed as a hemispherical structure, and the combustion chamber 7 and the base 6 form a relative rotational structure connected by a rotating shaft. The center of the spherical structure at the bottom of the combustion chamber 7 is located on the central axis of the rotating shaft connecting the combustion chamber 7 and the base 6. The angle adjustment mechanism includes an adjustment support 8 fixed in the middle of the base 6. The adjustment support 8 is generally arc-shaped, and the center of this arc coincides with the center of the spherical structure at the bottom of the combustion chamber 7. A slider 9 is fixed at the center of the bottom of the combustion chamber 7, and the slider 9 and the arc-shaped top of the adjustment support 8 are connected. A through-type sliding connection is formed; the slider 9 is set in the shape of "I" and the interior of the adjusting support 8 is hollow. The internal side of the adjusting support 8 is rotatably mounted with a take-up roller 10 and a guide roller 11 from bottom to top. The take-up roller 10 and the guide roller 11 are parallel to each other. A take-up rope 12 is installed between the take-up roller 10, the guide roller 11 and the slider 9. At the same time, a motor 13 is fixed on the outer wall of the adjusting support 8. The output shaft of the motor 13 and the central shaft of the take-up roller 10 are fitted with meshing bevel teeth.

[0043] After the organic matter combustion in the combustion chamber 7 of Example 1 is analyzed and detected for organic pollution, in order to facilitate the next analysis and detection of organic pollutants, the motor 13 is started. Under the mutual meshing action between the bevel teeth, the motor 13 drives the take-up roller 10 to rotate. The take-up roller 10 winds the take-up rope 12 on it. The take-up rope 12 moves through the guide roller 11 and pulls the slider 9 to slide through the arc surface of the adjusting support 8. Since the slider 9 and the combustion chamber 7 are fixedly connected, and the combustion chamber 7 and the base 6 are rotatably connected by a rotating shaft, when the slider 9 slides on the arc surface of the adjusting support 8, the combustion chamber 7 and the base 6 simultaneously change their angle deflection, changing the positioning angle of the combustion chamber 7. Under the effect of its angle change, it is convenient for the complete combustion reaction of the organic matter inside and the cleaning of the internal combustion by-products.

[0044] For example Figures 8-9 As shown, a reset cavity 14 is fixed on the side of the adjusting support 8 away from the take-up roller 10. A reset wheel 15 is rotatably installed inside the reset cavity 14 via a rotating shaft and bearing. An elastic element is also provided between the reset wheel 15 and the reset cavity 14. At the same time, a reset cable 16 is connected between the reset wheel 15 and the slider 9. The reset cable 16 is provided in a one-to-one correspondence with the take-up cable 12 and the reset wheel 15. The reset cable 16 and the reset cavity 14 are connected by a through sliding connection. The reset cable 16 is wound around the outside of the reset wheel 15.

[0045] When the combustion chamber 7 needs to change from a horizontally parallel positioning state to a vertically vertical state, the reverse start motor 13 drives the take-up roller 10 to rotate in the opposite direction. The take-up roller 10 no longer winds up the take-up cable 12, and the take-up cable 12 returns to a slack state. At this time, the reset wheel 15 is no longer pulled by the external force of the take-up cable 12. Under the elastic force of the elastic element, the elastic element on the reset wheel 15 begins to reset from its original tight and twisted state, driving the reset wheel 15 to rotate and wind the reset cable 16. The tension of the reset cable 16 is used to pull the combustion chamber 7, so that the combustion chamber 7 returns from a horizontally horizontal state to a vertically vertical state, and the next combustion reaction can proceed.

[0046] Example 3: Based on Example 2, the present invention as follows Figures 10-12 The process of cleaning up the sewage components was made public;

[0047] A cleaning and drainage component is installed through the side wall of the outer casing 1. The cleaning and drainage component is laterally coaxially distributed with the combustion chamber 7 and is used for cleaning, drying, and draining the inner wall of the combustion chamber 7. The cleaning and drainage component includes a cleaning cavity 17 installed through the right outer wall of the outer casing 1. A positioning housing 18 is provided on the side of the cleaning cavity 17 facing the inside of the outer casing 1. A hydraulic propulsion assembly is provided between the positioning housing 18 and the cleaning cavity 17. A cleaning turntable 19 is rotatably mounted in the middle of the positioning housing 18 via a bearing. The cleaning turntable 19 is laterally coaxially distributed with the combustion chamber 7, and the diameter of the cleaning turntable 19 is equal to the inner diameter of the port of the combustion chamber 7. The cleaning turntable 19 is aligned with the inner wall of the port of the combustion chamber 7. A sealing ring is provided on the outside of the connection; a guide pipe 20 is coaxially fixed on the back of the cleaning turntable 19, and an outer pipe 22 is fixed through the middle of the interior of the cleaning chamber 17. The guide pipe 20, the cleaning chamber 17 and the outer pipe 22 form a close-fitting through telescopic structure, and a turbine blade 21 is provided inside the guide pipe 20; a flow pipe 29 is fixed through the connection end of the guide pipe 20 and the cleaning turntable 19. The opening of the flow pipe 29 is located on the front of the cleaning turntable 19, and a return water hole 23 is provided through the cleaning turntable 19. One end of the drain pipe 24 is connected through the positioning housing 18, and the other end of the drain pipe 24 passes through the cleaning chamber 17 and is connected to the sewage pipe outside.

[0048] When the combustion chamber 7 needs to be cleaned in a horizontal state, the positioning housing 18 and the cleaning turntable 19 are moved toward the port of the combustion chamber 7 by the hydraulic components. The cleaning turntable 19 is directly embedded in the port of the combustion chamber 7. When the positioning housing 18 and the cleaning turntable 19 move, the outer pipe 22 and the guide pipe 20 extend and retract relative to each other without affecting the internal connection between them. Pressurized water and pressurized hot air are connected to the outside through the outer pipe 22 and introduced into the guide pipe 20. Under the action of the turbine blades 21, both the water flow and the air flow can drive the cleaning turntable 19 to rotate around the central axis. The cleaning components on the cleaning turntable 19 are used to clean the inner wall of the combustion chamber 7. When the water flow is introduced into the combustion chamber 7 through the guide pipe 20 and the flow pipe 29 to achieve flushing and cleaning of the combustion chamber 7, the wastewater generated by the cleaning action can be discharged through the return water hole 23 and the drain pipe 24 to avoid the residue of dirt in the combustion chamber 7. The hot air flow can dry the inside of the combustion chamber 7 after the dirt is cleaned.

[0049] At the same time, as Figure 12 As shown, one end of a folding brush 25 is embedded in the front of the cleaning turntable 19 at an equal angle and hinged. The other end of the folding brush 25 is fixed with a connector brush 26. A storage cavity 27 is also embedded in the front of the cleaning turntable 19. One end of a fastening cable 28 is connected to the storage cavity 27 through an elastic element. The other end of the fastening cable 28 passes through the storage cavity 27 and is connected to the outer wall of the folding brush 25. The opening of the flow tube 29 is located on the side of the hinge between the cleaning turntable 19 and the folding brush 25. The end of the flow tube 29 is magnetically set for the adsorption and positioning of the folding brush 25. The folding brush 25 is arranged in a one-to-one correspondence with the storage cavity 27 and the fastening cable 28. The folding brush 25 and the storage cavity 27 are distributed at intervals on the cleaning turntable 19.

[0050] When pressurized water or pressurized hot air is introduced into the combustion chamber 7 through the guide pipe 20 and the flow pipe 29, the driving force of the water and air can push the folded brush 25 on the cleaning turntable 19 to unfold and rotate. Under the centrifugal action of the rotating cleaning turntable 19, the folded brush 25 and the connector brush 26 unfold to clean the inner wall of the combustion chamber 7. When the cleaning and drying are finished and no more water or air is introduced, the folded brush 25 is reset under the action of the fastening cable 28 and the elastic element, and the positioning of the folded brush 25 is restored under the magnetic adsorption of the end of the folded brush 25 and the flow pipe 29.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
