Description

Technical Field

[0001] This utility model relates to the technical field of sodium sulfide production equipment, specifically to a sedimentation and filtration device for intelligent sodium sulfide production. Background Technology

[0002] Sodium sulfide, also known as sulfide, is an inorganic compound with the chemical formula Na₂S. It appears as a colorless crystalline powder, readily soluble in water, insoluble in ether, and slightly soluble in ethanol. It causes burns upon contact with skin and hair, hence its common name, sulfide. When exposed to air, sodium sulfide releases toxic hydrogen sulfide gas with a rotten egg odor. Industrial sodium sulfide, due to impurities, is pink, brownish-red, or yellowish-brown in color.

[0003] In the typical sodium sulfide production process, sodium sulfide is added to a settling tank while a neutralizing agent is added to the sodium sulfide solution to facilitate rapid settling. Therefore, it is crucial to ensure proper mixing between the sodium sulfide solution and the neutralizing agent during the settling process. This is typically achieved by installing a stirring device inside the settling tank to agitate the neutralizing agent and sodium sulfide, ensuring thorough mixing. However, when sodium sulfide is piped into the settling tank, the solution tends to concentrate in one area, preventing it from contacting the neutralizing agent upon arrival. This hinders the efficient mixing of the sodium sulfide and the neutralizing agent. Therefore, we propose an intelligent settling and filtration device for sodium sulfide production. Utility Model Content

[0004] To address the shortcomings of existing sedimentation and filtration equipment for intelligent sodium sulfide production, this invention provides a sedimentation and filtration device for intelligent sodium sulfide production. This device features a nozzle positioned inside a semi-circular jacket. As the nozzle rotates, a first helical gear simultaneously drives the nozzle to rotate, ensuring more uniform solution distribution when the nozzle carries the liquid downwards. This solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a sedimentation and filtration device for intelligent sodium sulfide production, comprising a sedimentation tank, a sedimentation collection tank for collecting impurities after sedimentation installed at the lower end of the sedimentation tank, a first limiting sleeve fixedly connected to the upper end of the outer side of the sedimentation tank, a filter screen movably sleeved inside the first limiting sleeve, a neutralizing liquid conveying pipe installed inside the upper end of the sedimentation tank, a top cover fitted on the upper part of the sedimentation tank, a motor installed on one side of the top cover, a first pulley fixedly connected to one end of the motor output shaft, a liquid distribution tank installed at the lower end of the top cover, a second pulley fixedly connected to the lower end of the liquid distribution tank, a semi-circular jacket fixedly connected to one side of the liquid distribution tank, and a stirring rod for stirring sodium sulfide fixedly connected to the lower part of the second pulley.

[0006] Preferably, the middle part of the first limiting sleeve is equipped with a liquid outlet for discharging liquid, and the filter screen is circular and is sleeved on the outside of the settling tank.

[0007] Preferably, a gear is fixedly connected to the lower end of the first pulley, and an auxiliary gear is installed on the outside of the filter screen, with the gear and the auxiliary gear meshing with each other.

[0008] Preferably, a belt is sleeved on the outside of the first pulley and the second pulley, and the first pulley, the belt and the second pulley are kept on the same plane.

[0009] Preferably, a connecting pipe is installed on the upper part of the liquid distribution box, the connecting pipe passes through the upper cover, and a sodium sulfide feed pipe is sleeved on the outside of the connecting pipe.

[0010] Preferably, a nozzle is movably fitted inside the semi-circular jacket, and a second limiting sleeve is installed at the lower end of the upper cover to limit the position of the nozzle. The inner side of the nozzle is in communication with the liquid distribution box.

[0011] Preferably, a first helical gear is fixedly connected to one end of the nozzle, and a second helical gear that meshes with the first helical gear is installed at the lower end of the upper cover.

[0012] Compared with existing intelligent sedimentation filtration equipment for sodium sulfide production, this utility model has the following advantages:

[0013] 1. This intelligent sodium sulfide production sedimentation and filtration equipment, by starting the motor, drives the first pulley to rotate, which in turn drives the liquid distribution box to rotate. Simultaneously, the connecting pipe transports sodium sulfide into the liquid distribution box. The liquid distribution box then drives the semi-circular jacket and the nozzle to rotate. The semi-circular jacket limits the position of the nozzle, while the nozzle drives the meshing motion between the first helical gear and the second helical gear. This ensures that the first helical gear drives the nozzle to rotate inside the semi-circular jacket, ensuring that the sodium sulfide is discharged uniformly. Through neutralization efficiency, this improves the subsequent sedimentation efficiency of sodium sulfide.

[0014] 2. This intelligent sedimentation filtration equipment for sodium sulfide production, when started by a motor, drives the gears to rotate, which in turn drives the filter screen to rotate inside the liquid outlet. As the filter screen rotates, the blockages adhering to the outside of the filter screen are scraped off, ensuring that the filter screen continuously filters sodium sulfide. This improves the filtration efficiency of sodium sulfide and eliminates the need for manual cleaning of the clogged areas of the filter screen, thus enhancing its intelligence.

[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A sedimentation and filtration device for intelligent sodium sulfide production includes a sedimentation tank 1, a sedimentation collection tank 2 for collecting impurities after sedimentation at the lower end of the sedimentation tank 1, and the sedimentation collection tank 2 for collecting the precipitated sodium sulfide. A first limiting sleeve 3 is fixedly connected to the upper end of the sedimentation tank 1, limiting the position of a filter screen 4. The filter screen 4 is movably fitted inside the first limiting sleeve 3, filtering the sodium sulfide. A neutralization liquid conveying pipe 6 is installed inside the upper end of the sedimentation tank 1, and a top cover 7 is fitted on the upper part of the sedimentation tank 1. A motor 8 is installed on one side of the upper cover 7. A first pulley 9 is fixedly connected to one end of the output shaft of the motor 8. When the motor 8 is started, the motor 8 drives the first pulley 9 to rotate. A liquid distribution box 12 is installed at the lower end of the upper cover 7. A second pulley 14 is fixedly connected to the lower end of the liquid distribution box 12. A semi-circular jacket 15 is fixedly connected to one side of the liquid distribution box 12. The semi-circular jacket 15 limits the position of the nozzle 16. At the same time, the nozzle 16 drives the solution to be transported into the sedimentation box 1. A stirring rod 20 for stirring sodium sulfide is fixedly connected to the lower part of the second pulley 14.

[0023] Please see Figure 5 The first limiting sleeve 3 has an outlet 5 installed in the middle to drive the liquid out. The filter screen 4 is circular and is sleeved on the outside of the settling tank 1. It is installed on the outside of the settling tank 1 through the first limiting sleeve 3. At the same time, the filter screen 4 is movably sleeved inside the first limiting sleeve 3. When sodium sulfide solution is injected into the settling tank 1, when the liquid overflows the first limiting sleeve 3, the solution is filtered through the filter screen 4. At the same time, the filtered liquid is discharged through the outlet 5. In the process of precipitating and filtering sodium sulfide, excess liquid is effectively discharged to ensure that more sodium sulfide is maintained inside the settling tank 1, so as to improve the precipitation efficiency of sodium sulfide.

[0024] Please see Figure 1A gear 10 is fixedly connected to the lower end of the first pulley 9. An auxiliary gear is installed on the outside of the filter screen 4. The gear 10 and the auxiliary gear are meshed with each other. Through the meshing connection between the gear 10 and the outside of the filter screen 4, the precipitated sodium sulfide will clog the inside of the filter screen 4 during the filtration process. By starting the motor 8, the gear 10 is driven to rotate, and the gear 10 drives the filter screen 4 to rotate. During the rotation of the filter screen 4, the clogged impurities can be scraped off, ensuring that the filter screen 4 continuously filters sodium sulfide. At the same time, after the filter screen 4 is flipped to the other side, the removed filter screen 4 can be cleaned to ensure that the filter screen 4 continuously filters sodium sulfide.

[0025] Please see Figure 3 A belt 11 is sleeved on the outside of the first pulley 9 and the second pulley 14. The first pulley 9, the belt 11, and the second pulley 14 are kept on the same plane. When the motor 8 is started, the motor 8 drives the first pulley 9 to rotate. The first pulley 9 drives the second pulley 14 to rotate through the belt 11. When the second pulley 14 rotates, it can drive the semi-circular jacket 15 and the stirring rod 20 to rotate. The semi-circular jacket 15 drives the material to rotate and add sodium sulfide, ensuring the uniformity of sodium sulfide addition. At the same time, when the stirring rod 20 rotates, it drives the sodium sulfide solution to stir, ensuring the sufficient mixing of sodium sulfide with the mixture during precipitation.

[0026] Please see Figure 3 A connecting pipe 13 is installed on the upper part of the liquid distribution tank 12. The connecting pipe 13 passes through the upper cover 7, and a sodium sulfide feed pipe is sleeved on the outside of the connecting pipe 13. The sodium sulfide solution can be transported to the inside of the liquid distribution tank 12 through the feed pipe. At the same time, the sodium sulfide can be continuously transported to the inside of the settling tank 1 through the liquid distribution tank 12, where the sodium sulfide is precipitated.

[0027] Please see Figure 4 The nozzle 16 is movably fitted inside the semi-circular jacket 15. A second limiting sleeve 19 is installed at the lower end of the upper cover 7 to limit the position of the nozzle 16. The inner side of the nozzle 16 is connected to the liquid distribution box 12. The nozzle 16 is fitted to the outside of the nozzle 16 through the semi-circular jacket 15 to ensure the stability of the nozzle 16. At the same time, the nozzle 16 has a liquid outlet hole on its outside, which can drive the liquid downward to be discharged. The semi-circular jacket 15 limits the easy output range of the nozzle 16.

[0028] Please see Figure 4One end of the nozzle 16 is fixedly connected to a first helical gear 17, and the lower end of the upper cover 7 is equipped with a second helical gear 18 that meshes with the first helical gear 17. During the rotation of the nozzle 16 driven by the liquid distribution box 12, the first helical gear 17 and the second helical gear 18 installed on the outside of the nozzle 16 mesh with each other, that is, the nozzle 16 rotates inside the semi-circular jacket 15. During the rotation of the nozzle 16, the sodium sulfide solution can be discharged downward in different directions to ensure that the sodium sulfide is uniformly added.

[0029] Working principle: In use, neutralizing liquid is added into the settling tank 1 through the neutralizing liquid delivery pipe 6. At the same time, the connecting pipe 13 drives the sodium sulfide to be transported into the liquid distribution tank 12. The first pulley 9 is started, and the first pulley 9 drives the connecting pipe 13 to rotate through the second pulley 14. That is, the liquid distribution tank 12 drives the nozzle 16 to rotate. During the rotation of the nozzle 16, the first helical gear 17 and the second helical gear 18 mesh with each other. Then, the nozzle 16 drives the sodium sulfide to rotate and be discharged downward, ensuring that the sodium sulfide inlet pipe and the neutralizing liquid are fully mixed. When the stirring rod 20 rotates, it can drive the sodium sulfide to be stirred, which improves the intelligence of sodium sulfide precipitation and filtration. Sodium sulfide is easily transported and overflows the filter screen 4. The filter screen 4 filters the sodium sulfide. The liquid is discharged through the liquid outlet 5. When the stirring rod 20 stops rotating, the sodium sulfide can be precipitated in the settling tank 1. The precipitated sodium sulfide is collected and discharged through the sediment collection box 2.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
