Description

Technical Field

[0001] The invention relates to the technical field of concentrated sulfuric acid dilution, and in particular to a high-efficiency concentrated sulfuric acid automatic dilution device. Background Art

[0002] Concentrated sulfuric acid is an important basic raw material in the chemical industry. It is widely used in the manufacture of fertilizers, medicines, explosives, pigments, detergents and batteries. It is also used in industrial fields such as petroleum refining, metal smelting, and dye production. In these applications, concentrated sulfuric acid usually needs to be diluted to a suitable concentration to meet different process requirements.

[0003] In the existing production process, when the concentrated sulfuric acid is diluted, the concentrated sulfuric acid is usually poured from the top of the dilution container, slowly contacted with water and continuously stirred, so that the concentrated sulfuric acid and water are locally mixed and diluted, and the water is prevented from boiling violently under the action of the concentrated sulfuric acid and causing the concentrated sulfuric acid to splash out. Although this method is safer, it also makes the injection speed of the concentrated sulfuric acid into the water slower, which in turn makes the dilution efficiency of the concentrated sulfuric acid low. Even so, the concentrated sulfuric acid still releases huge heat when it is diluted, causing part of the water and sulfuric acid to be atomized to form acid mist and escape, resulting in part of the sulfuric acid being wasted, and affecting the dilution accuracy of the sulfuric acid.

The pushing component is respectively connected between the dilution tank 1 and the concentrated sulfuric acid storage tank 9. The setting of the pushing component can control the output rate of the concentrated sulfuric acid in the concentrated sulfuric acid storage tank 9, so that the concentrated sulfuric acid is output slowly in small quantities, and then contacts and dilutes with the water flow in the dilution tank 1, taking into account the efficiency and safety of the concentrated sulfuric acid dilution process; a transmission component is used to drive the stirring shaft 7 and the stirring impeller 8 to rotate and stir in the dilution tank 1. The transmission component is respectively connected between the first rotating shaft 12, the second rotating shaft 13 and the stirring shaft 7. The transmission component can use the driving device of the pushing component to drive the stirring shaft 7 and the stirring impeller 8 to work, so that the pushing component The structure of the component and the driving component form a match and work synchronously; the opening and closing component is used to cooperate with the input and output of concentrated sulfuric acid in the concentrated sulfuric acid storage tank 9, and to open and close the concentrated sulfuric acid output channel 20. The opening and closing component is connected to the concentrated sulfuric acid storage tank 9. The opening and closing component can be opened when the concentrated sulfuric acid storage tank 9 outputs concentrated sulfuric acid, so that the concentrated sulfuric acid can flow out smoothly through the concentrated sulfuric acid output channel 20. At the same time, it can also cooperate with the stirring shaft 7 and the stirring impeller 8 to stir, and further enhance the stirring and mixing effect during the dilution process. Secondly, during the process of the concentrated sulfuric acid input pipe 3 replenishing concentrated sulfuric acid into the concentrated sulfuric acid storage tank 9, the opening and closing component can also remain closed, and the concentrated sulfuric acid output channel 20 is closed to ensure the storage effect of the concentrated sulfuric acid storage tank 9 on the concentrated sulfuric acid.

[0029] In this embodiment, if Figure 1 to Figure 2 as well as Figures 5 and 6As shown, the top ends of the water supply pipe 2, the concentrated sulfuric acid input pipe 3 and the balancer 4 all extend to above the top of the dilution tank 1, and the bottom ends of the water supply pipe 2 and the balancer 4 all extend to below the partition 6. The bottom end of the concentrated sulfuric acid input pipe 3 is connected to the bottom of the concentrated sulfuric acid storage tank 9. The bottom end of the concentrated sulfuric acid storage tank 9 is provided with a concentrated sulfuric acid input channel 21 connected to the bottom end of the concentrated sulfuric acid input pipe 3. The concentrated sulfuric acid input channel 21 leads to the interior of the concentrated sulfuric acid storage tank 9. The bottom end of the dilution tank 1 is fixedly connected to a dilute sulfuric acid output pipe 34. The water supply pipe 2 is used to input water into the dilution tank 1. Therefore, the bottom end of the water supply pipe 2 needs to be below the partition 6 to ensure that the water can enter the dilution tank 1. The concentrated sulfuric acid input pipe 3 is used to input water into the concentrated sulfuric acid storage tank 9. Concentrated sulfuric acid is input into the sulfuric acid storage tank 9, and the input of concentrated sulfuric acid into the concentrated sulfuric acid storage tank 9 is also carried out from the bottom of the concentrated sulfuric acid storage tank 9. Therefore, a concentrated sulfuric acid input channel 21 is set to allow concentrated sulfuric acid to be input from the bottom of the concentrated sulfuric acid storage tank 9, which can facilitate the work of the push component. After the dilution of concentrated sulfuric acid is completed in the dilution tank 1, dilute sulfuric acid is obtained, and the dilute sulfuric acid is discharged through the dilute sulfuric acid output pipe 34. The balancer 4 is used for balancing the air pressure inside and outside the dilution tank 1 during the dilution of concentrated sulfuric acid. It can also maintain the air pressure balance of the inner and outer walls of the dilution tank 1 during the water flow input and the output of dilute sulfuric acid to ensure safety during the dilution process. The principle and use of the balancer 4 are the same as those in the prior art and will not be described in detail here.

[0030] In this embodiment, if Figures 2 to 7As shown, the pushing assembly includes a servo motor 5 fixedly connected to the middle part of the top of the dilution tank 1 and a second gear 15 fixedly connected to the top of the concentrated sulfuric acid storage tank 9, the top of the first rotating shaft 12 is fixedly connected to the driving shaft of the servo motor 5, and the bottom end of the first rotating shaft 12 is fixedly connected to the input shaft of the second gear 15, and the output shaft of the second gear 15 is fixedly connected to the outside with a threaded rod 23 extending to the inside of the concentrated sulfuric acid storage tank 9. After working, the servo motor 5 can directly drive the first rotating shaft 12 to rotate through its driving shaft, and then drive the input shaft of the second gear 15 to rotate. After the deceleration effect of the second gear 15, the transmission of the output shaft of the second gear 15 drives the threaded rod 23 to rotate, so that the threaded rod 23 rotates slowly, and drives the pushing assembly to push and output the concentrated sulfuric acid. The principle and usage of the second gear 15 are the same as those in the prior art, and will not be repeated here. The threaded rod 23 is movably connected to the concentrated sulfuric acid storage tank 9 through a bearing, and the bearing connection between the threaded rod 23 and the concentrated sulfuric acid storage tank 9 ensures the rotational activity of the threaded rod 23 in the concentrated sulfuric acid storage tank 9. A push plate 18 is movably sleeved in the concentrated sulfuric acid storage tank 9, and a threaded tube 17 is fixedly connected to the push plate 18. Guide rods 22 symmetrically distributed on both sides of the threaded tube 17 are fixedly connected to the push plate 18. The threaded tube 17 is threadedly connected to the threaded rod 23. After the threaded rod 23 rotates slowly under the action of the output shaft of the second gear 15, the threaded tube 17 is pushed to slide in the concentrated sulfuric acid storage tank 9 through the threaded connection between the threaded tube 17, and then the threaded rod 23 is driven to rotate slowly under the action of the output shaft of the second gear 15. The movable push plate 18 slides in the concentrated sulfuric acid storage tank 9, and squeezes out the concentrated sulfuric acid stored in the concentrated sulfuric acid storage tank 9 through the concentrated sulfuric acid output channel 20. A guide tube 16 corresponding to the position of the guide rod 22 is fixedly connected to the concentrated sulfuric acid storage tank 9, and the guide tube 16 is sleeved on the outside of the guide rod 22. The push plate 18 synchronously drives the guide rod 22 to move during the sliding process in the concentrated sulfuric acid storage tank 9, and the guide rod 22 slides in the guide tube 16, so that the guide tube 16 and the guide rod 22 provide limiting and guiding for the push plate 18 during the movement of the push plate 18, thereby ensuring the stability of the push plate 18 in the process of pushing sulfuric acid to be discharged from the concentrated sulfuric acid storage tank 9.

[0031] In this embodiment, if Figures 1 to 4As shown, the transmission assembly includes a synchronous wheel 10 fixedly connected to the outside of the stirring shaft 7, the first rotating shaft 12 and the second rotating shaft 13, and the middle parts of the first rotating shaft 12 and the second rotating shaft 13 are respectively fixedly connected with the first gear 14 and the second gear 15, and the first gear 14 and the second gear 15 are meshed with each other. The synchronous wheels 10 on the first rotating shaft 12 are symmetrically distributed on the upper and lower sides of the first gear 14, and the synchronous wheels 10 on the second rotating shaft 13 are symmetrically distributed on the upper and lower sides of the second gear 15. There are four stirring shafts 7, two stirring shafts 7 close to the second rotating shaft 13 form a group, and the other two stirring shafts 7 form a group. A synchronous belt 11 is sleeved between the synchronous wheel 10 on the stirring shaft 7 of one group close to the second rotating shaft 13 and the synchronous wheel 10 on the second rotating shaft 13. The synchronous wheel 10 on the stirring shaft 7 of one group away from the second rotating shaft 13 is also connected to the synchronous wheel 10 on the first rotating shaft 12 through the synchronous belt 11. The setting of the transmission component can utilize the operation of the servo motor 5 to drive the stirring shaft 7 and the stirring impeller 8 to rotate. When the servo motor 5 is working, the first rotating shaft 12 rotates through its drive shaft, and the first rotating shaft 12 and the second rotating shaft 13 are connected through the first gear 14 and the second gear 15 is meshed for transmission, so that the first rotating shaft 12 and the second rotating shaft 13 rotate in opposite directions respectively. Under the transmission action of the synchronous wheel 10 and the synchronous belt 11, the first rotating shaft 12 drives one group of two stirring shafts 7 to rotate, and the second rotating shaft 13 drives the other group of two stirring shafts 7 to rotate in the opposite direction, thereby making the two stirring shafts 7 symmetrically distributed outside the concentrated sulfuric acid storage tank 9 and outside the concentrated sulfuric acid output channel 20 rotate in opposite directions, and the generated water flow direction guides the concentrated sulfuric acid output from the concentrated sulfuric acid output channel 20 to areas far away from each other for dilution, so as to avoid the concentrated sulfuric acid output from the concentrated sulfuric acid output channel 20 from converging close to each other and generating high temperature, thereby further ensuring the safety of the dilution process.

[0032] In this embodiment, if Figures 5 to 11As shown, the opening and closing assembly includes a closing plate 19 fixedly connected to the outer side of the bottom end of the concentrated sulfuric acid storage tank 9, a connecting end 29 is provided at the connection between the closing plate 19 and the concentrated sulfuric acid storage tank 9, and a first deformation zone 25 bent in a C shape is provided on the outside of the closing plate 19, the thickness value and the width value at the first deformation zone 25 are both smaller than the thickness value and the width value of other areas on the closing plate 19, the setting of the first deformation zone 25 makes the strength of the closing plate 19 at the first deformation zone 25 weaker, and then during the concentrated sulfuric acid output process in the concentrated sulfuric acid storage tank 9, the closing plate 19 can bend and deform at the first deformation zone 25, and open the concentrated sulfuric acid output channel 20, to ensure that the operation of concentrated sulfuric acid dilution can be carried out normally, and the setting of the connecting end 29 makes the thickness value of the connection between the closing plate 19 and the concentrated sulfuric acid storage tank 9 larger and the strength higher , to ensure the stability of the connection between the concentrated sulfuric acid storage tank 9 and the closing plate 19, a symmetrically distributed closing block 30 is arranged on the side of the closing plate 19 close to the outside of the concentrated sulfuric acid storage tank 9, and the closing block 30 is adapted to the shape of the concentrated sulfuric acid output channel 20. When the concentrated sulfuric acid storage tank 9 is not outputting concentrated sulfuric acid, or when concentrated sulfuric acid is input through the concentrated sulfuric acid input pipe 3, the closing plate 19 maintains a closed state under its own elastic force and the hydraulic pressure inside and outside the concentrated sulfuric acid storage tank 9. At this time, the closing block 30 is embedded in the concentrated sulfuric acid output channel 20, and the concentrated sulfuric acid output channel 20 is closed in cooperation with the closing plate 19, thereby ensuring the storage effect of the concentrated sulfuric acid storage tank 9 on the concentrated sulfuric acid, and also preventing the concentrated sulfuric acid input pipe 3 from inputting concentrated sulfuric acid into the concentrated sulfuric acid storage tank 9, and causing the closing plate 19 to open, resulting in dilute sulfuric acid entering the concentrated sulfuric acid storage tank 9.

[0033] In this embodiment, if Figures 8 to 13As shown, the two sides of the closing plate 19 are symmetrically connected with extended edges 26, the extended edges 26 are inclined in the opposite direction away from the outside of the concentrated sulfuric acid storage tank 9, and the ends of the extended edges 26 extend to the outside of the concentrated sulfuric acid storage tank 9 and bend toward the outside of the concentrated sulfuric acid storage tank 9, and the outside of the stirring shaft 7 is fixedly connected with a pressure plate 28 corresponding to the position of the extended edge 26, the end of the pressure plate 28 is bent at 90° toward the direction of the extended edge 26, and an arc surface is provided on the outside of the bending part of the pressure plate 28. The outside of the closing plate 19 is fixedly connected to the extended edge 26 with uniformly distributed reinforcing ribs, and the outside of the extended edge 26 is provided with a second deformation zone 27, and the thickness and width values ​​at the second deformation zone 27 are both smaller than the thickness and width values ​​of other areas on the extended edge 26. In the process of concentrated sulfuric acid storage tank 9 outputting concentrated sulfuric acid to dilution tank 1 through concentrated sulfuric acid output channel 20, closing plate 19 is in an open state, and the synchronous stirring shaft 7 drives stirring impeller 8 to rotate, so as to promote the mixing of concentrated sulfuric acid and water flow in dilution tank 1. During the rotation of stirring shaft 7, pressure plate 28 is synchronously driven to rotate, so that pressure plate 28 contacts the end of extended edge 26 outside closing plate 19, and pressure plate 28 contacts extended edge 26 after contacting extended edge 26, so that extended edge 26 drives the deformation of closing plate 19 at first deformation zone 25 to intensify, and at the same time, extended edge 26 is also bent and deformed at second deformation zone 27, until the end of pressure plate 28 contacts the second deformation zone 27 is separated, and the closing plate 19 is reset to a certain extent under the action of its own elastic force. As the pressure plate 28 follows the rapid rotation of the stirring shaft 7, the pressure plate 28 repeatedly contacts and separates from the extended edge 26, so that the closing plate 19 is repeatedly displaced, and disturbances are generated outside the concentrated sulfuric acid output channel 20, further enhancing the contact and mixing effect between the concentrated sulfuric acid output from the concentrated sulfuric acid output channel 20 and the water flow in the dilution tank 1. In the process of replenishing concentrated sulfuric acid in the concentrated sulfuric acid storage tank 9 through the concentrated sulfuric acid input pipe 3, the first rotating shaft 12, the second rotating shaft 13 and the threaded rod 23 all rotate in the opposite direction, thereby driving the stirring shaft 7 and the stirring impeller 8 to rotate in the opposite direction. When the concentrated sulfuric acid storage tank 9 is closed outside the concentrated sulfuric acid output channel 20, the pressure plate 28 will also squeeze the outside of the extended edge 26 in the opposite direction, squeezing the extended edge 26 and the closing plate 19 toward the outside of the concentrated sulfuric acid storage tank 9, further enhancing the sealing effect of the closing plate 19 on the concentrated sulfuric acid output channel 20.

[0034] In this embodiment, if Figures 8 to 12As shown, the closing plate 19 is symmetrically connected to a connecting plate 33 on one side facing the outside of the concentrated sulfuric acid storage tank 9, the connecting plate 33 is located between the two groups of closing blocks 30, and the end of the connecting plate 33 is fixedly connected to a stirring plate 31, and guide surfaces 32 are provided on both sides of the stirring plate 31. A through groove 24 adapted to the size of the stirring plate 31 is provided at the bottom of the concentrated sulfuric acid storage tank 9. The closing plate 19 repeatedly displaces, and in the process of generating disturbances outside the concentrated sulfuric acid output channel 20, the connecting plate 33 and the stirring plate 31 are synchronously displaced. The setting of the connecting plate 33 can form a The partition further avoids the intersection of the concentrated sulfuric acid discharged from the two concentrated sulfuric acid output channels 20. The existence of the agitator plate 31 can increase the contact area between the closing plate 19 and the water flow, thereby making the turbulence effect generated during the reciprocating movement of the closing plate 19 stronger, thereby accelerating the dilution and mixing efficiency of the concentrated sulfuric acid. The through groove 24 is used to form a storage for the agitator plate 31 and the connecting plate 33 when the closing plate 19 is closed. The setting of the guide surface 32 makes the end surface area of ​​the agitator plate 31 facing the concentrated sulfuric acid storage tank 9 smaller, smaller than the inlet area of ​​the through groove 24, and it is easy for the agitator plate 31 to enter the through groove 24.
