Technical Field

[0001] This utility model relates to the field of sulfur melting kettle technology, and in particular to a sulfur melting kettle anti-clogging device. Background Technology

[0002] Traditional sulfur melting kettles are generally used to treat unconcentrated sulfur foam and desulfurization waste liquid. They have low production efficiency and usually require multiple sulfur melting kettles to complete the production task. They also produce a large amount of high-temperature clear liquid, which needs to be cooled before it can be returned to the desulfurization system.

[0003] A sulfur melting kettle anti-clogging device, disclosed in patent document publication number CN104368278B, includes a filter-type sulfur melting kettle. It comprises a clear liquid section, a filtration section, and a sulfur melting section arranged sequentially from top to bottom within the kettle body. The filtration section is equipped with a rotating filter screen, driven by a drive device located at the top of the kettle. The clear liquid section has a clear liquid outlet, the filtration section has a sulfur foam inlet, and the sulfur melting section has a sulfur outlet at the bottom. The rotating filter screen is a cage-type screen that can rotate around its axis, and a fixed scraper is provided on the kettle body outside the rotating filter screen. However, this patent still has some shortcomings: sulfur foam easily adheres and accumulates at the mesh openings of the rotating filter screen, causing it to clog. Utility Model Content

[0004] To address the problem of sulfur foam easily adhering and accumulating at the mesh of the rotating filter, causing clogging, this invention provides an anti-clogging device for the sulfur melting kettle. The technical solution adopted by this utility model to solve its technical problem is: a sulfur melting kettle anti-clogging device, including a sulfur melting kettle, the sulfur melting kettle having a filter chamber and a sulfur melting chamber, the filter chamber being provided with a filter mechanism and an anti-clogging mechanism, the filter mechanism including a filter cylinder and a partition plate, the partition plate being fixed inside the sulfur melting kettle to separate the filter chamber, the bottom of the filter cylinder being fixed to the partition plate, the side of the filter cylinder having mesh openings, the filter cylinder and the filter chamber forming a clear liquid chamber, the anti-clogging mechanism including a main shaft, a connecting rod and a defoaming plate, the main shaft being rotatably installed at the center of the filter chamber, one end of the connecting rod being fixedly connected to the main shaft, the other end of the connecting rod being rotatably connected to one side edge of the defoaming plate, the other side edge of the defoaming plate being in contact with the inner wall of the filter cylinder. Preferably, a torsion spring seat is also installed at the connection between the connecting rod and the defoaming plate, the torsion spring seat being used to push the defoaming plate to rotate toward the inner wall of the filter cylinder.

[0005] Preferably, the anti-clogging mechanism further includes a liquid suction roller shaft and rolling gear teeth. The rolling gear teeth are rotatably mounted on the side of the defoaming plate away from the torsion spring seat. The liquid suction roller shaft is coaxially and fixedly connected to the rolling gear teeth and fits against the inner wall of the filter cylinder. The teeth of the rolling gear teeth can be embedded in the mesh of the filter cylinder.

[0006] Preferably, the anti-clogging mechanism further includes a squeezing roller and a shaft seat. The shaft seat is fixed to the defoaming plate, and the end of the squeezing roller is rotatably mounted on the shaft seat. The squeezing roller is located on the side of the defoaming plate away from the inner wall of the filter cylinder. The circumferential surface of the squeezing roller abuts against the circumferential surface of the liquid-absorbing roller shaft and is embedded in the liquid-absorbing roller shaft. The length of the squeezing roller is greater than the length of the liquid-absorbing roller shaft.

[0007] Preferably, the liquid-absorbing roller shaft is a heat-insulating sponge shaft, and the squeezing roller is a smooth metal roller shaft.

[0008] Preferably, the bottom of the filter cylinder is provided with a through hole, and the partition plate is provided with a discharge port communicating with the through hole. A butterfly valve for closing the discharge port is installed at the discharge port, and the discharge port can connect the filter chamber and the sulfur melting chamber.

[0009] The beneficial effects of this utility model are as follows: An anti-clogging mechanism is provided. The main shaft of the anti-clogging mechanism drives the defoaming plate to move along the inner wall of the filter cylinder. When the defoaming plate moves, the side with rolling teeth is always pushed by the torsion spring seat to fit against the inner wall of the filter cylinder. Therefore, when the defoaming plate moves, it drives the rolling teeth to roll along the inner wall of the filter cylinder, which in turn drives the liquid-absorbing roller shaft to rotate. One side of the liquid-absorbing roller shaft rolls against the filter cylinder, absorbing the foam on the inner wall of the filter cylinder and achieving defoaming. Then, the other side of the liquid-absorbing roller shaft is squeezed by the squeeze roller to squeeze out the clear liquid absorbed by the liquid-absorbing roller shaft. This causes the squeezed and dehydrated part of the liquid-absorbing roller shaft to rotate back to the inner wall of the filter cylinder, achieving repeated absorption of foam. Furthermore, the liquid-absorbing roller shaft itself is flexible. During the rolling process along the inner wall of the filter cylinder, it can also sink into the mesh of the filter cylinder to absorb the foam in the mesh, improving the filtration effect of the filter cylinder.

Detailed Implementation

[0013] 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.

[0014] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figures 1 to 5 As shown, this utility model provides an embodiment of an anti-clogging device for a sulfur melting kettle 1, including a sulfur melting kettle 1. The sulfur melting kettle 1 has a filter chamber and a sulfur melting chamber. The filter chamber is provided with a filter mechanism 2 and an anti-clogging mechanism 3. The filter mechanism 2 includes a filter cylinder 4 and a partition plate 5. The partition plate 5 is fixed inside the sulfur melting kettle 1 to separate the filter chamber. The bottom of the filter cylinder 4 is fixed on the partition plate 5. The side of the filter cylinder 4 is provided with a mesh. The filter cylinder 4 separates the clear liquid in the sulfur foam from the elemental sulfur. A clear liquid chamber is formed between the filter cylinder 4 and the filter chamber. The filtered clear liquid passes through the filter cylinder 4 and enters the clear liquid chamber. Then it is discharged through the liquid outlet pipe of the sulfur melting kettle 1. The liquid outlet pipe is connected to a liquid pump to improve the efficiency of clear liquid discharge.

[0016] The anti-clogging mechanism 3 includes a main shaft 6, a connecting rod 7, and a defoaming plate 8. The main shaft 6 is rotatably installed in the center of the filter chamber. One end of the connecting rod 7 is fixedly connected to the main shaft 6, and the other end of the connecting rod 7 is rotatably connected to one side edge of the defoaming plate 8. A torsion spring seat 9 is also installed at the connection between the connecting rod 7 and the defoaming plate 8. The torsion spring seat 9 is used to push the defoaming plate 8 to rotate toward the inner wall of the filter cylinder 4. The other side edge of the defoaming plate 8 is in contact with the inner wall of the filter cylinder 4. The defoaming plate 8 can first crush the accumulated sulfur foam and break the larger sulfur foam. At the same time, the defoaming plate 8 moves along the inner wall of the filter cylinder 4 and can also scrape off the excess sulfur, preventing the sulfur from clogging the filter cylinder 4. The anti-clogging mechanism 3 also includes a liquid-absorbing roller shaft 10 and rolling wheel teeth 11. The rolling wheel teeth 11 are rotatably mounted on the side of the defoaming plate 8 away from the torsion spring seat 9. The liquid-absorbing roller shaft 10 and the rolling wheel teeth 11 are coaxially fixedly connected and fit against the inner wall of the filter cylinder 4. The liquid-absorbing roller shaft 10 is a heat-insulating sponge shaft, which improves the service life of the liquid-absorbing roller shaft 10 in high-temperature environments. The teeth of the rolling wheel teeth 11 can be embedded in the mesh of the filter cylinder 4 to prevent the rolling wheel teeth 11 from slipping during rotation. After the teeth are embedded in the mesh, they can provide greater friction for the rolling wheel teeth 11, so that the rolling wheel teeth 11 can drive the squeezed liquid-absorbing roller shaft 10 to rotate smoothly, thereby squeezing out the clear liquid absorbed by the liquid-absorbing roller shaft 10.

[0017] The anti-clogging mechanism 3 also includes a squeezing roller 12 and a bearing seat 13. The bearing seat 13 is fixed on the defoaming plate 8. The end of the squeezing roller 12 is rotatably mounted on the bearing seat 13. The squeezing roller 12 is located on the side of the defoaming plate 8 away from the inner wall of the filter cylinder 4. The circumferential surface of the squeezing roller 12 abuts against the circumferential surface of the liquid suction roller shaft 10 and is embedded in the liquid suction roller shaft 10. The squeezing roller 12 is a smooth metal roller shaft to prevent elemental sulfur from adhering to the surface of the squeezing roller 12. The smooth surface of the squeezing roller 12 can also avoid damaging the liquid suction roller shaft 10. The length of the squeezing roller 12 is greater than the length of the liquid suction roller shaft 10 so that the squeezing roller 12 can squeeze and dehydrate various parts of the liquid suction roller shaft 10.

[0018] The working principle of the anti-clogging mechanism 3 is as follows: The main shaft 6 drives the defoaming plate 8 to move along the inner wall of the filter cylinder 4 via the connecting rod 7. When the defoaming plate 8 moves, the side with the rolling gear teeth 11 is always pushed by the torsion spring seat 9 to be in contact with the inner wall of the filter cylinder 4. Therefore, when the defoaming plate 8 moves, it will drive the rolling gear teeth 11 to roll along the inner wall of the filter cylinder 4, and then drive the liquid suction roller shaft 10 to rotate through the rolling gear teeth 11. One side of the liquid suction roller shaft 10 rolls in contact with the filter cylinder 4, absorbing the foam on the inner wall of the filter cylinder 4. The foam is removed by the suction roller 12, and then the other side of the suction roller 10 is squeezed by the squeezing roller 12 to squeeze out the clear liquid absorbed by the suction roller 10. The part of the suction roller 10 that has been squeezed and dehydrated rotates again to the inner wall of the filter cylinder 4 to achieve repeated absorption of foam. In addition, the suction roller 10 itself is flexible. As the suction roller 10 rolls along the inner wall of the filter cylinder 4, it can also fall into the mesh of the filter cylinder 4 to absorb the foam in the mesh and improve the filtration effect of the filter cylinder 4.

[0019] The bottom of the filter cylinder 4 has a through hole, and the partition plate 5 has a discharge port 14 that communicates with the through hole. A butterfly valve is installed at the discharge port 14 to close the discharge port 14. The discharge port 14 can connect the filter chamber and the sulfur melting chamber. After the butterfly valve is opened, the filtered elemental sulfur can be discharged into the sulfur melting chamber through the discharge port 14. This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this application. The above are only preferred embodiments of this application. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the scope of protection of this application.
