Technical Field
[0001] This utility model relates to the technical field of industrial solid waste detection, and in particular to a combustion titration device for detecting the sulfur content of industrial solid waste. Background Technology
[0002] The detection of sulfur content in industrial solid waste is of great significance for environmental protection and resource recycling. Sulfur in industrial solid waste undergoes complex chemical reactions in the natural environment, transforming into pollutants such as sulfur dioxide and hydrogen sulfide. These gases not only contribute to acid rain, corrode buildings, and damage vegetation, but also seriously threaten human respiratory health. Accurate detection of sulfur content can effectively guide resource recycling. If the sulfur content meets the standards, some substances in industrial solid waste can be reprocessed into industrial raw materials, realizing resource recycling, reducing dependence on primary resources, lowering production costs, and promoting green and sustainable development. Therefore, a combustion titration device for detecting sulfur content in industrial solid waste is particularly needed.
[0003] However, current methods for detecting sulfur content in industrial solid waste largely rely on manual operation to feed samples into the combustion furnace. This is not only slow but also unstable, easily leading to deviations in sample placement due to variations in force and angle. This results in inconsistent sample placement within the furnace, making it difficult to maintain uniform combustion conditions across different batches or even different samples from the same batch. Consequently, combustion efficiency is affected, potentially preventing the complete conversion of sulfur into detectable gaseous forms. This reduces the accuracy of test results from the outset. Furthermore, the time-consuming manual feeding severely restricts overall testing efficiency, making it unsuitable for large-scale industrial solid waste testing. The lack of an effective sample preheating mechanism means that samples entering the furnace require a considerable amount of time to reach the temperature needed for complete combustion, prolonging the combustion process. Insufficient and uneven mixing also leads to poor mixing of the titrant with the sulfur-containing gas, resulting in a slow and incomplete titration reaction, further complicating the overall testing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a combustion titration device for detecting sulfur content in industrial solid waste. This addresses the problems mentioned in the background section, where existing methods for detecting sulfur content in industrial solid waste rely heavily on manual operation to feed samples into the combustion furnace. This manual operation is slow and unstable, easily leading to deviations in sample placement due to variations in force and angle. This results in inconsistent sample placement within the combustion furnace, making it difficult to maintain consistent combustion conditions between different batches or even different samples from the same batch. Consequently, the combustion effect is affected, potentially preventing the complete conversion of sulfur in the sample into detectable gaseous forms, thus reducing the accuracy of the detection results from the source. Furthermore, the time-consuming manual feeding severely restricts overall detection efficiency, making it unsuitable for large-scale industrial solid waste detection. Additionally, the lack of an effective sample preheating mechanism means that samples entering the combustion furnace require a long time to reach the temperature needed for complete combustion, prolonging the combustion process. Insufficient and uneven stirring also results in poor mixing of the titrant with the sulfur-containing gas, leading to a slow and incomplete titration reaction, resulting in excessively long titration times and impacting overall detection efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a combustion titration device for detecting the sulfur content of industrial solid waste, comprising an operating table, a connecting plate fixedly installed on the top of the operating table, a pushing component disposed on the outer side of the connecting plate, a connecting pipe disposed on the outer side of the pushing component, a combustion furnace fixedly installed on the top of the operating table, an exhaust port opened on the outer side of the combustion furnace, a transmission pipe connected through the top of the combustion furnace, a titration component disposed on the top of the transmission pipe, the titration component comprising a titration cylinder body, the titration cylinder body being mounted on the transmission pipe, and the titration...

[0011] Preferably, the preheating pipe is located at the bottom of the connecting pipe, and the connecting pipe is in a through connection with the combustion furnace.
[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This combustion titration device for detecting sulfur content in industrial solid waste, by setting up a pushing component and using an electric cylinder to drive the pushing, not only has a faster pushing speed and higher stability, reducing the time spent on manual operation, but also can accurately control the sample pushing position, ensuring that the sample enters the designated area in the combustion furnace for combustion, laying the foundation for an efficient and stable combustion process. It can ensure that the sample enters the combustion furnace in the same position each time, reducing the impact of sample position deviation on the combustion effect. The preheating chamber can preheat the sample, shortening the temperature rise time of the sample in the combustion furnace, accelerating the combustion process, and enabling combustion in a short time. By completely converting sulfur in the sample into a detectable gaseous form, the overall detection efficiency is further improved. Ensuring complete conversion of sulfur guarantees detection accuracy from the source. The titration component allows for thorough stirring and dispersion of the solution within the burette, enabling rapid and uniform mixing of the titrant with the introduced sulfur-containing gas. This significantly increases the titration reaction rate and completeness, effectively shortens the titration time, and substantially improves detection efficiency. It also allows for precise control of the amount of titrant added, avoiding detection errors caused by adding too much or too little titrant. Combined with thorough stirring and mixing, this ensures the accuracy of the titration reaction, facilitating the acquisition of accurate sulfur content detection results. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5This utility model provides a technical solution: a combustion titration device for detecting sulfur content in industrial solid waste, comprising an operating table 1, a connecting plate 2 fixedly installed on the top of the operating table 1, a pushing component 3 arranged on the outer side of the connecting plate 2, a connecting pipe 4 arranged on the outer side of the pushing component 3, a combustion furnace 5 fixedly installed on the top of the operating table 1, an exhaust port 6 opened on the outer side of the combustion furnace 5, a transmission pipe 7 connected through the top of the combustion furnace 5, and a titration component 8 arranged on the top of the transmission pipe 7; the titration component 8 includes a titration cylinder body 801, the titration cylinder body 801 is installed on the transmission pipe 7, a titration flow control pump 802 is arranged on the top of the titration cylinder body 801, a cover 803 is fixedly installed on the top of the titration flow control pump 802, a threaded groove 804 is opened on the inner side of the cover 803, a plug 805 is arranged on the top of the cover 803, and a threaded groove 806 is opened on the outer side of the plug 805; the titration cylinder body 801... An inner support frame 807 is provided, and a protective cover 808 is fixedly installed on the top of the support frame 807. A motor 809 is fixedly installed at the bottom inside the protective cover 808. A rotating shaft 810 is fixedly installed at the output end of the motor 809. A stirring plate 811 is fixedly installed on the outer side of the rotating shaft 810. A rotating roller 812 is fixedly installed on the top of the rotating shaft 810. A dispersing plate 813 is fixedly installed on the outer side of the rotating roller 812. By setting up the titration component 8, the solution in the titration cylinder body 801 can be fully stirred and dispersed, so that the titrant and the sulfur-containing gas introduced can be quickly and uniformly mixed, which greatly improves the titration reaction rate and reaction sufficiency, effectively shortens the titration time, significantly improves the detection efficiency, and can accurately control the amount of titrant added, avoiding detection errors caused by adding too much or too little titrant. Combined with thorough stirring and mixing, the accuracy of the titration reaction is ensured, which is conducive to obtaining accurate sulfur content detection results.
[0021] Furthermore, the first threaded groove 804 and the second threaded groove 806 are adapted to each other, and the cover 803 and the plug 805 are threadedly connected. By setting the first threaded groove 804 and the second threaded groove 806, the connection between the cover 803 and the plug 805 is more tight and firm. This not only effectively prevents the solution from leaking into the titration cylinder body 801 and the entry of outside air, but also facilitates the quick disassembly of the plug 805 when it is necessary to add titrant or maintain internal components. This makes the operation convenient and improves the flexibility of the device.
[0022] Furthermore, the support frame 807 has a cross-shaped structure, and the stirring blade 811 and the protective cover 808 do not contact each other. By setting the stirring blade 811 and the protective cover 808, collisions and friction between the stirring blade 811 and the protective cover 808 during rotation are avoided, reducing wear on components and lowering noise during device operation. At the same time, while providing stable support for the protective cover 808 and the motor 809, the support frame 807 minimizes the occupation of the internal space of the burette body 801, does not hinder the flow and stirring of the solution, and ensures smooth stirring.
[0023] Furthermore, multiple sets of the stirring blades 811 are arranged in a ring around the outside of the rotating shaft 810. Multiple sets of the dispersing blades 813 are also arranged in a ring around the outside of the rotating roller 812. By using the stirring blades 811 and the dispersing blades 813, the solution can be stirred from different angles, creating a more complex flow state and improving the uniformity of the stirring. The dispersing blades 813 can more comprehensively cut and disperse the sulfur-containing gas, breaking it down into smaller bubbles, increasing the contact area between the gas and the titrant, further promoting the full reaction, and thus improving the accuracy of the titration results.
[0024] Furthermore, the pushing component 3 includes a mounting base plate 301, which is mounted on the outside of the connecting plate 2. An electric cylinder 302 is fixedly mounted on the outside of the mounting base plate 301. A telescopic rod 303 is fixedly mounted on the movable end of the electric cylinder 302. A push plate 304 is fixedly mounted on the end of the telescopic rod 303 away from the electric cylinder 302. A placement platform 305 is fixedly mounted on the top of the operating table 1. A baffle 306 is fixedly mounted on the top of the placement platform 305. A preheating chamber 307 is fixedly mounted on the top of the operating table 1. A preheating chamber 307 is fixedly mounted at the bottom inside the preheating chamber 307. The preheating tube 308 and the preheating chamber 307 are equipped with a temperature display screen 309 on the outside and a sensor 310 on the top of the preheating chamber 307. The push component 3 is set up and driven by an electric cylinder 302. The push is faster and more stable, reducing the time spent on manual operation. It can also accurately control the push position of the sample, ensuring that the sample enters the designated area in the combustion furnace 5 for combustion. This lays the foundation for an efficient and stable combustion process and ensures that the sample enters the combustion furnace 5 in the same position each time, reducing the impact of sample position deviation on the combustion effect.
[0025] Furthermore, the push plate 304 contacts the placement stage 305, and two identical sets of baffles 306 are provided, with the two sets of baffles 306 symmetrically distributed about the vertical center line of the placement stage 305. By setting two sets of baffles 306, the sample placed on the placement stage 305 can be limited to prevent the sample from shifting or falling during the pushing process, ensuring that the sample can accurately enter the pushing path. In conjunction with the push plate 304, the accuracy and stability of sample pushing are further improved, providing a reliable guarantee for the subsequent preheating and combustion processes.
[0026] Furthermore, the preheating pipe 308 is located at the bottom of the connecting pipe 4, which is connected to the combustion furnace 5. By setting the preheating pipe 308 at the bottom of the connecting pipe 4 and connecting the connecting pipe 4 to the combustion furnace 5, the preheating efficiency is improved, allowing the sample to reach a certain temperature before entering the combustion furnace 5. This ensures that the preheated sample can smoothly enter the combustion furnace 5 for complete combustion, reduces heat loss during sample transport, ensures efficient combustion reaction, and is conducive to the complete conversion of sulfur in the sample.
[0027] Working principle: First, the operator pre-treats the industrial solid waste sample to be tested, crushing it into uniform particles to ensure complete combustion. Then, the operator opens the limiting area on the placement platform 305 in the pushing assembly 3, placing the pre-treated sample at the center of the platform 305. Two sets of symmetrically distributed baffles 306 limit the sample, preventing it from shifting during the pushing process. The electric cylinder 302 in the pushing assembly 3 is then activated, driving the telescopic rod 303 to extend and retract, which in turn moves the push plate 304 along the surface of the placement platform 305, precisely placing the sample... The sample is pushed into the connecting tube 4. After entering the connecting tube 4, the preheating tube 308 at the bottom of the preheating chamber 307 starts working to preheat the sample. The operator can monitor the preheating temperature in real time through the temperature display screen 309 on the outside of the preheating chamber 307. At the same time, the sensor 310 on the top detects whether the sample has reached the preset preheating position to ensure that the preheating process is accurate and controllable. After preheating, the sample enters the designated area in the combustion furnace 5 through the connecting tube 4. The combustion furnace 5 starts and heats up to the preset combustion temperature to fully combust the sample and remove the sulfur element from the sample. The gas is completely converted into sulfur-containing gas. Excess gas produced during combustion is discharged through the exhaust port 6 outside the combustion furnace 5. The sulfur-containing gas produced during combustion enters the titration cylinder body 801 of the titration assembly 8 through the transmission pipe 7 at the top of the combustion furnace 5 to prepare for the subsequent titration reaction. The plug 805 at the top of the cover 803 in the titration assembly 8 is opened, and a certain amount of titrant is added to the titration cylinder body 801 through the titration flow control pump 802. After the addition is completed, the plug 805 is closed, and the motor 809 inside the protective cover 808 is started. The motor 809 drives the rotating shaft. Rotation of roller 810 drives multiple sets of annularly distributed stirring blades 811 to stir the titrant. At the same time, multiple sets of dispersing blades 813 on the rotating roller 812 disperse the sulfur-containing gas, so that the gas and titrant are quickly and evenly mixed and react. After the titration reaction is completed, the sulfur content in the sample is calculated based on the titrant consumption recorded by the titration flow control pump 802 and the reaction equation, thus completing the entire detection process. After the detection is completed, the plug 805 can be opened again to clean or maintain the titration cylinder body 801 to ensure the accuracy of the device in the next use.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
