Description

Technical Field

[0001] The utility model relates to the technical field of refined concentrated sulfuric acid dilution, and specifically relates to a dilution device for refined concentrated sulfuric acid. Background Technique

[0002] Concentrated sulfuric acid is commonly known as "bad water", which is a strong mineral acid with high corrosiveness. "Bad water" refers to a sulfuric acid solution with a mass fraction greater than or equal to 70%. Concentrated sulfuric acid has strong oxidizing properties at high concentrations, which is one of the biggest differences between it and ordinary sulfuric acid or ordinary concentrated sulfuric acid. At the same time, it also has dehydration, strong oxidizing properties, strong corrosiveness, low volatility, acidity, etc.

[0003] When the existing dilution device adds sulfuric acid dropwise, the dropping tube is attached to the inner wall of the dilution tube. As the dropping operation continues, the dropping tube is likely to separate from the inner wall of the dilution tube under the buoyancy of the liquid, which will cause the sulfuric acid to change from slowly sliding into the water body to quickly dropping into the water body. This change has certain safety hazards. Now, a dilution device for refined concentrated sulfuric acid is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dilution device for refined concentrated sulfuric acid to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A dilution device for refined concentrated sulfuric acid includes a housing mechanism. A diversion mechanism is fixedly connected inside the housing mechanism, and a stirring mechanism is arranged on the housing mechanism.

[0007] The diversion mechanism includes a U-shaped inclined plate. A baffle is fixedly connected to the U-shaped inclined plate. The discharge end of the U-shaped inclined plate is fixedly connected to a funnel, and the output end of the funnel is fixedly connected to an L-shaped diversion pipe.

[0008] Further improvement of the technical solution of the utility model lies in that: A buffer plate is fixedly connected inside the L-shaped diversion pipe. The output end of the L-shaped diversion pipe is fixedly connected to a conical discharge cover, and a discharge hole is opened on the conical discharge cover. The buffer plate can prevent concentrated sulfuric acid from directly falling to the bottom of the L-shaped diversion pipe, thereby improving the smoothness of the flow of concentrated sulfuric acid.

[0009] Further improvement of the technical solution of the utility model lies in that: The housing mechanism includes a dilution barrel. The funnel and the L-shaped diversion pipe are both fixedly connected to the dilution barrel. The conical discharge cover is located inside the dilution barrel. A water adding pipe is fixedly connected to the dilution barrel. When water needs to be added, water is added into the dilution barrel through the water adding pipe.

[0010] A further improvement of the technical solution of the present utility model lies in that: a flow guide plate is fixedly connected to the discharge port of the water adding pipe, and an annular bracket is fixedly connected to the top of the dilution barrel. The flow guide plate can block the water, relieve the impact force of the water, and at the same time make the water flow along the inner wall of the dilution barrel, thereby avoiding the phenomenon of splashing.

[0011] A further improvement of the technical solution of the present utility model lies in that: the stirring mechanism includes teeth, a limiting frame is fixedly connected inside the teeth, and a rotating bead is rotatably connected to the limiting frame. The rotating bead is subjected to frictional force and rotates accordingly, which can improve the smoothness of the rotation of the limiting frame.

[0012] A further improvement of the technical solution of the present utility model lies in that: the limiting frame is rotatably connected to the annular bracket, and the rotating bead is in contact with the annular bracket. A gear is meshed with the teeth, and an electric rotating rod is fixedly connected to the gear. When the electric rotating rod operates, it drives the gear to rotate, thereby driving the limiting frame to rotate through the teeth.

[0013] A further improvement of the technical solution of the present utility model lies in that: one end of the electric rotating rod is sleeved on the top of the dilution barrel, a main stirring rod is fixedly connected to the inner wall of the limiting frame, and a secondary stirring rod is fixedly connected to the main stirring rod. The secondary stirring rod moves along with the main stirring rod, which can expand the stirring range, thereby improving the dilution quality and efficiency.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] 1. The present utility model provides a dilution device for refined concentrated sulfuric acid. The concentrated sulfuric acid is poured from the U-shaped inclined plate, and the concentrated sulfuric acid flows into the funnel along the U-shaped inclined plate, then enters the L-shaped flow guide pipe, and finally enters the conical discharge cover. The concentrated sulfuric acid enters the dilution barrel through the discharge hole. During the flow of the concentrated sulfuric acid, the baffle can prevent the concentrated sulfuric acid from splashing when it is poured, and the buffer plate can prevent the concentrated sulfuric acid from directly falling to the bottom of the L-shaped flow guide pipe, thereby improving the smoothness of the flow of the concentrated sulfuric acid and further improving the safety during dilution.

[0016] 2. The present utility model provides a dilution device for refined concentrated sulfuric acid. Start the electric rotating rod to drive the gear to rotate, thereby driving the limiting frame to rotate through the teeth. Since the rotating bead is in contact with the annular bracket, when rotating, the rotating bead is subjected to frictional force and rotates accordingly, which can improve the smoothness of the rotation of the limiting frame. When the limiting frame rotates, it can drive the main stirring rod to rotate around the center of the dilution barrel, and the secondary stirring rod moves accordingly, which can expand the stirring range, thereby improving the dilution quality and efficiency.

Specific embodiments

[0022] The following further describes the present utility model in detail with reference to the embodiments:

[0023] Embodiment 1

[0024] As Figures 1-4 shown, the present utility model provides a dilution device for refined concentrated sulfuric acid, including a housing mechanism 2. A diversion mechanism 1 is fixedly connected inside the housing mechanism 2. A stirring mechanism 3 is arranged on the housing mechanism 2. The diversion mechanism 1 includes a U-shaped inclined plate 11. A baffle 12 is fixedly connected to the U-shaped inclined plate 11. A funnel 13 is fixedly connected to the discharge end of the U-shaped inclined plate 11. An L-shaped diversion pipe 14 is fixedly connected to the output end of the funnel 13. A buffer plate 15 is fixedly connected inside the L-shaped diversion pipe 14. A conical discharge cover 16 is fixedly connected to the output end of the L-shaped diversion pipe 14. A discharge hole 17 is opened on the conical discharge cover 16;

[0025] Specifically, water is first poured into the dilution barrel 21 so that the water is at the bottom of the dilution barrel 21. Subsequently, concentrated sulfuric acid is poured from the U-shaped inclined plate 11. The concentrated sulfuric acid flows along the U-shaped inclined plate 11 into the funnel 13, then into the L-shaped diversion pipe 14, and finally into the conical discharge cover 16. The concentrated sulfuric acid enters the dilution barrel 21 through the discharge hole 17. During the flow of the concentrated sulfuric acid, the baffle 12 can prevent the concentrated sulfuric acid from splashing when it is poured, and the buffer plate 15 can prevent the concentrated sulfuric acid from directly falling to the bottom of the L-shaped diversion pipe 14, thereby improving the smoothness of the flow of the concentrated sulfuric acid and further improving the safety during dilution.

[0026] Embodiment 2

[0027] As Figures 1-4As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the housing mechanism 2 includes a dilution barrel 21, a funnel 13 and an L-shaped diversion pipe 14 are both fixedly connected to the dilution barrel 21, a conical discharge cover 16 is located inside the dilution barrel 21, a water adding pipe 22 is fixedly connected to the dilution barrel 21, a diversion plate 23 is fixedly connected to the discharge port of the water adding pipe 22, and an annular bracket 24 is fixedly connected to the top of the dilution barrel 21;

[0028] Specifically, a heat dissipation port is provided at the top of the dilution barrel 21, so that the heat generated during the dilution process can diffuse out through the heat dissipation port. When water needs to be added, the water is added into the dilution barrel 21 through the water adding pipe 22. The diversion plate 23 can block the water, relieve the impact force of the water, and at the same time make the water flow along the inner wall of the dilution barrel 21, thereby avoiding the phenomenon of splashing.

[0029] Embodiment 3

[0030] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the stirring mechanism 3 includes teeth 31, a limiting frame 32 is fixedly connected inside the teeth 31, a rotating bead 33 is rotatably connected to the limiting frame 32, the limiting frame 32 is rotatably connected to the annular bracket 24, and the rotating bead 33 is in contact with the annular bracket 24. A gear 34 is meshed with the teeth 31, an electric rotating rod 35 is fixedly connected to the gear 34, one end of the electric rotating rod 35 is sleeved on the top of the dilution barrel 21, a main stirring rod 36 is fixedly connected to the inner wall of the limiting frame 32, and a sub-stirring rod 37 is fixedly connected to the main stirring rod 36;

[0031] Specifically, before the concentrated sulfuric acid enters the dilution barrel 21, the electric rotating rod 35 is started to drive the gear 34 to rotate, so as to drive the limiting frame 32 to rotate through the teeth 31. Since the rotating bead 33 is in contact with the annular bracket 24, when rotating, the rotating bead 33 is subjected to frictional force and rotates accordingly, which can improve the smoothness of the rotation of the limiting frame 32. When the limiting frame 32 rotates, it can drive the main stirring rod 36 to rotate around the center of the dilution barrel 21, and the sub-stirring rod 37 moves accordingly, which can expand the stirring range and thus improve the dilution quality and efficiency.

[0032] Next, the working principle of the dilution equipment for refined concentrated sulfuric acid will be specifically described.

[0033] As Figures 1-4As shown in the figure, pour water into the dilution bucket 21 first, so that the water is at the bottom of the dilution bucket 21. Start the electric rotating rod 35 to drive the gear 34 to rotate, and then drive the limiting frame 32 to rotate through the teeth 31, which can drive the main stirring rod 36 to rotate around the center of the dilution bucket 21. The auxiliary stirring rod 37 will move accordingly, which can expand the stirring range. Then pour concentrated sulfuric acid from the U-shaped inclined plate 11. The concentrated sulfuric acid flows along the U-shaped inclined plate 11 into the funnel 13, then into the L-shaped diversion pipe 14, and finally into the conical discharge cover 16. The concentrated sulfuric acid enters the dilution bucket 21 through the discharge hole 17. During the flow of the concentrated sulfuric acid, the baffle 12 can prevent the concentrated sulfuric acid from splashing, and the buffer plate 15 can reduce the impact force when the concentrated sulfuric acid slows down. When water needs to be added, add water into the dilution bucket 21 through the water inlet pipe 22. The diversion plate 23 can block the water and relieve the impact force of the water, improving the safety of dilution.
