Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to an online sampler for a phosphorus-free conversion reactor with a filter assembly. Background Technology

[0002] In the production process of phosphorus-free converters, parameters such as the composition and concentration of materials in the reactor need to be monitored in real time through online sampling to ensure that the product quality meets the process requirements. Since the phosphorus-free converter reaction liquid may contain undissolved raw material particles or reaction by-product impurities, direct sampling can easily lead to blockage of the sampling pipeline and deviation of the test data. Therefore, online samplers with filter components have become key equipment.

[0003] Existing online samplers for phosphorus-free conversion reactors typically consist of a single-channel sampling tube, a single-layer filter, a manual shut-off valve, and a sample collection bottle. One end of the single-channel sampling tube is inserted into the reactor via welding or flange connection. A single-layer metal filter and a manual shut-off valve are connected in series in the middle of the sampling tube. During sampling, the shut-off valve is opened, and the reaction liquid in the reactor flows through the sampling tube under the action of pressure difference. After the single-layer filter removes some large particulate impurities, the liquid flows directly into the sample collection bottle to complete the sampling. The sampling tube and the filter are usually fixedly connected, and tools are needed to disassemble and replace or deeply clean the filter.

[0004] Existing online samplers still have room for improvement in terms of filtration accuracy and ease of maintenance of filter components. Due to the use of a single-layer filter, while choosing a large-pore filter can reduce the probability of clogging, it is difficult to effectively remove trace amounts of fine impurities in the reaction solution. These impurities can easily enter the testing equipment with the sample, leading to deviations in test results, or accumulate and clog subsequent sampling pipes over time. If a small-pore filter is chosen, although the filtration accuracy can be improved, it is easily clogged by undissolved raw material particles, requiring frequent shutdowns for maintenance. The filter in the sampler is often fixedly connected to the sampling tube. When the filter is clogged and requires deep cleaning or replacement, the reactor feed must be shut off, the sampling tube flange or welded joint must be disassembled, and tools such as wrenches must be used to remove the sampling tube to take out the filter. The entire maintenance process is time-consuming. Therefore, an online sampler for a phosphorus-free conversion agent reactor with a filter component is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an online sampler for a phosphorus-free conversion agent reactor with a filter assembly, aiming to improve the existing online samplers, which still have room for optimization in terms of filtration accuracy and ease of maintenance of filter components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online sampler for a phosphorus-free conversion agent reactor with a filter assembly, comprising a reactor body, a lower connecting block fixedly connected to the outer wall of the reactor body, an upper connecting block disposed above the lower connecting block, a connecting pipe fixedly connected to the inner wall of the upper connecting block, a sampling pipe threadedly connected to the inner wall of the connecting pipe, a sampler body fixedly connected to one end of the sampling pipe, and a filter mechanism disposed on the inner wall of the connecting pipe;

[0007] The filtration mechanism includes a filter basket, a first filter pad, and a second filter pad. The outer wall of the filter basket is slidably connected to the inner wall of the connecting tube. The outer walls of the first and second filter pads are fixedly connected to the inner wall of the filter basket. A sealing ring is fixedly connected to the upper surface of the filter basket. The outer wall of the sealing ring is in contact with the lower surface of the sampling tube. A connecting ring is provided on the lower surface of the filter basket. A first spring is fixedly connected to the lower surface of the connecting ring. One end of the first spring is fixedly connected to the inner wall of the connecting tube.

[0008] Furthermore, a fixing block is fixedly connected to the outer wall of the lower connecting block, and the outer wall of the fixing block is fixedly connected to the outer wall of the reactor body.

[0009] Furthermore, a sliding rod is slidably connected to the inner wall of the fixed block, and a limit block is fixedly connected to the outer wall of the sliding rod.

[0010] Furthermore, a screw is slidably connected to the inner wall of the limiting block, and a rotating block is threadedly connected to the outer wall of the screw.

[0011] Furthermore, the outer wall of the limiting block is slidably connected to the inner wall of the upper connecting block, and the rotating block is disposed on the outer wall of the limiting block.

[0012] Furthermore, a second fixing block and a third fixing block are fixedly connected to the upper surface of the first fixing block, and a second spring is fixedly connected to the upper surface of the second fixing block.

[0013] Furthermore, the second spring is disposed below the limiting block, and the second spring is sleeved on the outer wall of the screw.

[0014] Furthermore, a spring is fixedly connected to the outer wall of the fixed block three, and one end of the spring is fixedly connected to the outer wall of the sliding rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a double-layer filtration and detachable structure consisting of a filter basket, filter pad one, and filter pad two is used. The reaction liquid is first coarsely filtered by filter pad two to remove undissolved raw material particles, and then finely filtered by filter pad one to remove trace impurities. When the filter components need to be cleaned, the sampling tube is turned to drive the sampler body to detach from the connecting tube. The compressed spring one drives the connecting ring to push the filter basket upward, making it easy to remove the filter basket to clean filter pad one and filter pad two. This achieves the effect of improving the filtration accuracy of the reaction liquid, ensuring the sampling quality, simplifying the disassembly process of the filter components, and reducing the maintenance difficulty.

[0017] 2. In this utility model, the overall disassembly and assembly structure is composed of a screw, a rotating block, and a limiting block. During disassembly, the rotating block slides up along the screw, and the protrusion drives the limiting block and the sliding rod to slide and stretch the spring three, quickly releasing the fixation of the device. Through the connection and cooperation of this structure, the effect of quickly completing the disassembly and assembly of the entire sampling device without complicated tools is achieved, avoiding the time-consuming and laborious problems of traditional disassembly and assembly methods, improving the operational efficiency during equipment maintenance and replacement, while ensuring the structural stability after installation and reducing the labor intensity of operators.

[0027] 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.

[0028] Reference Figures 1-5 An embodiment of this utility model is provided: an online sampler for a phosphorus-free conversion agent reactor with a filter assembly, including a reactor body 1. The reactor body 1 is used to store the phosphorus-free conversion agent reaction liquid to be sampled, providing a source of raw materials for the sampling operation. At the same time, its internal pressure environment is the benchmark for pressure balance during the sampling process, ensuring that the reaction liquid can smoothly enter the sampling device under the action of pressure difference. A lower connecting block 17 is fixedly connected to the outer wall of the reactor body 1, and an upper connecting block 16 is provided above the lower connecting block 17.

[0029] A connecting pipe 3 is fixedly connected to the inner wall of the upper connecting block 16. A sampling pipe 4 is threadedly connected to the inner wall of the connecting pipe 3. The connecting pipe 3 serves as a material conveying channel between the reactor body 1 and the sampling pipe 4, receiving the phosphorus-free conversion agent reaction liquid flowing out of the reactor and conveying it to the sampling pipe 4. At the same time, when installing the sampling device, it needs to be inserted through the lower connecting block 17 into the reactor body 1. One end of the sampling pipe 4 is fixedly connected to the sampler body 5. The sampler body 5 is equipped with a sample chamber, a balance valve, a sampling valve, and a flow valve. It is the core carrier of the sampling operation. The sample chamber is used to temporarily store the reaction liquid to be collected. The balance valve controls the pressure balance between the reactor and the sample chamber. The sampling valve controls the reaction liquid to enter the sample chamber. The flow valve controls the reaction liquid in the sample chamber to flow into the sampling bottle. The orderly control of the sampling process is achieved through the coordinated operation of each valve. A filter mechanism is provided on the inner wall of the connecting pipe 3.

[0030] The filtration mechanism includes a filter basket 7, a filter pad 1 9, and a filter pad 2 10. The outer wall of the filter basket 7 is slidably connected to the inner wall of the connecting pipe 3. The outer walls of the filter pad 1 9 and the filter pad 2 10 are fixedly connected to the inner wall of the filter basket 7. The filter pad 1 9 is located at the upper position inside the filter basket 7 and is a fine filtration component. Its filter pores are small in diameter, which can further filter the reaction liquid after the coarse filtration by the filter pad 2 10, remove the trace impurities remaining in the reaction liquid, and prevent trace impurities from clogging the subsequent sampling tube 4, sample chamber, or flow valve, thus ensuring unobstructed sampling channels and sample purity.

[0031] Filter pad 2 10 is located at the bottom of filter basket 7 and is a coarse filter component. Its filter pores are larger and can preferentially filter the reaction liquid flowing in from the connecting pipe 3, filter out any undissolved raw material particles that may be present in the reaction liquid, prevent large particles from scratching or clogging the filter pad 1 9 above, extend the service life of filter pad 1 9, and reduce the pressure of subsequent fine filtration. A sealing ring 6 is fixedly connected to the upper surface of filter basket 7. The outer wall of sealing ring 6 is in contact with the lower surface of sampling tube 4. A connecting ring 11 is provided on the lower surface of filter basket 7, and a spring 1 8 is fixedly connected to the lower surface of connecting ring 11.

[0032] The filter basket 7 is used to house filter pad 9 and filter pad 10, providing a support frame for their installation. This allows the filter pads 9 and 10 to stably receive the flowing reaction liquid. Simultaneously, it can be moved upwards by spring 8 and connecting ring 11 for easy removal by operators, facilitating cleaning of the internal filter pads 9 and 10. One end of spring 8 is fixedly connected to the inner wall of connecting pipe 3. Normally, spring 8 is in a compressed state. When sampling tube 4 pulls sampler body 5 away from connecting pipe 3, spring 8 releases its elastic potential energy, causing connecting ring 11 to spring upwards, thus pushing the filter basket 7 upwards. This prevents the filter basket 7 from getting stuck and difficult to remove, providing power assistance for disassembling and cleaning the filter basket 7. A fixing block 2 is fixedly connected to the outer wall of the lower connecting block 17, and the outer wall of fixing block 2 is fixedly connected to the outer wall of the reactor body 1.

[0033] Specifically, the reactor body 1 stores the reaction liquid to be sampled, provides the sampling raw materials and pressure reference, and ensures that the reaction liquid enters the sampling device under the action of pressure difference. The lower connecting block 17 and the upper connecting block 16 cooperate to assist the installation and positioning of the sampling device. The connecting pipe 3 serves as the material channel between the reactor body 1 and the sampling pipe 4, transporting the reaction liquid and providing a place for the filter mechanism to be installed. The sampling pipe 4 transports the filtered reaction liquid, and the sampler body 5 can be detached from the connecting pipe 3 by twisting, providing conditions for the maintenance of the filter components.

[0034] The sampler body 5 is equipped with a sample chamber, a balance valve, a sampling valve, and a flow valve. The sample chamber temporarily stores the reaction liquid. The balance valve controls the pressure balance between the reaction vessel and the sample chamber. The sampling valve controls the reaction liquid to enter the sample chamber. The flow valve controls the reaction liquid to flow into the sampling bottle. The orderly sampling is achieved through the coordinated operation of the valves. In the filtration mechanism, the filter basket 7 carries the filter pad 9 and the filter pad 10, providing installation support for the two filter pads. It can also be moved upward under the push of the spring 8 and the connecting ring 11 for easy removal and cleaning. The filter pad 10 coarsely filters out undissolved raw material particles in the reaction liquid, preventing scratches or blockages to the filter pad 9 and extending its service life.

[0035] The filter pad 9 removes trace impurities to prevent clogging of subsequent pipes and valves, ensuring unobstructed sampling channels and sample purity. The sealing ring 6 fits the sampling tube 4 and the filter basket 7 to prevent leakage. The spring 8 is normally compressed, and when the sampling tube 4 is separated from the connecting tube 3, it releases elastic potential energy, which pushes the filter basket 7 upward through the connecting ring 11, assisting in the removal of the filter basket 7 and simplifying maintenance operations. The fixing block 2 is fixed between the lower connecting block 17 and the reactor body 1, providing installation support for subsequent disassembly and assembly of components.

[0036] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 A sliding rod 12 is slidably connected to the inner wall of the fixed block 12. A limit block 13 is fixedly connected to the outer wall of the sliding rod 12. A screw 14 is slidably connected to the inner wall of the limit block 13. A rotating block 15 is threadedly connected to the outer wall of the screw 14. The screw 14 has a thread on its outer side, which cooperates with the internal thread of the rotating block 15 to provide a threaded transmission track for the up and down sliding of the rotating block 15. When the rotating block 15 is rotated, the rotating block 15 can move up and down precisely along the thread of the screw 14, thereby pushing or releasing the limit block 13, ensuring the stability and accuracy of the movement of the rotating block 15. The outer wall of the limit block 13 is slidably connected to the inner wall of the upper connecting block 16.

[0037] Rotating block 15 is set on the outer wall of limiting block 13. When the sampling device is installed, the reset limiting block 13 can abut against the upper connecting block 16 to prevent the sampling device from moving up and down. When disassembling, it moves upward with the protrusion of rotating block 15 to release the limit on the upper connecting block 16 and drive sliding rod 12 to slide. Fixed block 19 and fixed block 20 are fixedly connected to the upper surface of fixed block 12. Spring 18 is fixedly connected to the upper surface of fixed block 19. Spring 18 is set below limiting block 13. Sliding rod 12 can slide up and down in the groove of fixed block 12. When disassembling the sampling device, it slides upward with limiting block 13 and stretches spring 21. When installing, it slides downward under the reset force of spring 21 and drives limiting block 13 to reset.

[0038] Spring 21 is fixedly connected to the outer wall of screw 14 and fixedly connected to the outer wall of fixing block 20. One end of spring 21 is fixedly connected to the outer wall of sliding rod 12. Spring 21 is connected between sliding rod 12 and fixing block 20. When the sampling device is disassembled, it is stretched by sliding rod 12 and stores elastic potential energy. When installed, it releases elastic potential energy and drives sliding rod 12 to slide downward, thereby resetting limit block 13 and limiting the upper connecting block 16. This provides reset power for the installation and fixation of the sampling device. There is no need to manually reset limit block 13, which simplifies the installation operation and improves installation efficiency.

[0039] Specifically, the sliding rod 12 slides on the inner wall of the fixed block 12. When disassembling, it slides up with the limiting block 13 to stretch the spring 3 21. When installing, it slides down under the restoring force of the spring 3 21, driving the limiting block 13 to reset. It is the core component of the disassembly and assembly transmission. When installing, the limiting block 13 abuts against the upper connecting block 16 to prevent the sampling device from loosening. When disassembling, it moves up with the rotating block 15 to release the limit on the upper connecting block 16 and control the disassembly and assembly state of the device. The screw 14 is threadedly engaged with the rotating block 15. The rotating block 15 can slide up and down along the screw 14. When sliding, the limiting block 13 is pushed or released by the protrusion.

[0040] The operator can fix and unlock the device by rotating the rotating block 15, which improves the convenience of operation. The second fixing block 19 supports the second spring 18. The second spring 18 is sleeved on the outer wall of the screw 14 and located below the limit block 13. It buffers the impact force when the limit block 13 is reset and avoids rigid collision and wear of the parts. The third fixing block 20 supports the third spring 21. The third spring 21 connects the sliding rod 12 and the third fixing block 20. When disassembling, it is stretched and stores potential energy. When installing, it releases potential energy to drive the sliding rod 12 and the limit block 13 to reset, providing power for installation and fixing. There is no need for manual reset, which simplifies the installation process and improves the efficiency of disassembly and assembly.

[0041] Working principle: When it is necessary to sample the phosphorus-free conversion agent in the reactor body 1, first open the balance valve on the sampler body 5 so that the pressure in the reactor can be transmitted to the sample chamber of the sampler through the balance pipe until the pressure in the sample chamber is consistent with the pressure in the reactor. After the pressure is balanced, open the sampling valve. Under the action of pressure difference, the reaction liquid in the reactor flows slowly from the connecting pipe 3. First, it passes through the filter pad 10 in the filter basket 7 for coarse filtration to remove any undissolved raw material particles that may exist in the reaction liquid. Then, it passes through the filter pad 9 above for fine filtration to remove trace impurities and avoid clogging the subsequent pipes.

[0042] The filtered reaction liquid flows into the sampling tube 4 and finally into the sample chamber. A sealing ring 6 is provided between the sampling tube 4 and the connecting tube 3 to effectively prevent leakage. When the sample chamber has collected a sufficient amount of sample, the sampling valve and the balance valve are closed, and the flow valve is opened to allow the reaction liquid in the sample chamber to flow into the sampling bottle on one side. When it is necessary to clean the filter pad 9 and filter pad 10 in the filter basket 7, the sampling tube 4 is turned so that it drives the sampler body 5 to directly detach from the connecting tube 3. At this time, the compressed spring 8 will drive the connecting ring 11 to spring up, thereby pushing the filter basket 7 to move upward, making it convenient to remove the filter basket 7 for cleaning.

[0043] If the entire sampling device needs to be disassembled and replaced, rotate the rotating block 15 on the outside of the screw 14 so that the rotating block 15 slides upward along the thread. During this process, the protrusion on one side of the rotating block 15 will abut against the limiting block 13, causing the limiting block 13 to move upward, thereby causing the limiting block 13 to drive the sliding rod 12 to slide in the groove of the fixed block 1 2. At the same time, the fixed block 3 20 cooperates with the sliding rod 12 to stretch the spring 3 21, thus realizing the quick disassembly of the entire sampling device.

[0044] When installing the sampling device, insert the connecting pipe 3 through the lower connecting block 17 into the reactor body 1, and then rotate the rotating block 15 in the opposite direction to move it downward. When the protrusion on one side of the rotating block 15 no longer abuts against the limiting block 13, the stretched spring 3 21 will drive the sliding rod 12 to reset, thereby resetting the limiting block 13 and limiting the upper connecting block 16. At the same time, the spring 2 18 below the limiting block 13 can play a buffering role, and finally the sampling device is quickly installed.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
