[0043] like Figures 1 to 13 As shown, an embodiment of the present invention provides a high-efficiency automatic concentrated sulfuric acid dilution device, including a dilution tank 1, a concentrated sulfuric acid storage tank 9 installed in the dilution tank 1, and a partition 6 fixedly connected to the top of the concentrated sulfuric acid storage tank 9. The dilution tank 1 is the place where concentrated sulfuric acid comes into contact with water and is mixed and diluted. The concentrated sulfuric acid storage tank 9 is used to store the concentrated sulfuric acid to be diluted. The partition 6 forms a partitioned space in the area above the concentrated sulfuric acid storage tank 9 in the dilution tank 1, which is used to place related equipment and structures that need to work during the concentrated sulfuric acid dilution process, and to prevent their working environment from being affected by the heat generated during the concentrated sulfuric acid dilution process. The bottom of the concentrated sulfuric acid storage tank 9 has uniformly distributed concentrated sulfuric acid output channels 20. The opening of the concentrated sulfuric acid output channels 20 makes the concentrated sulfuric acid output position in the concentrated sulfuric acid storage tank 9 at the bottom area of ​​the internal space of the dilution tank 1, thereby making the concentrated sulfuric acid... The contact and mixing point between sulfuric acid and water is below the water surface, allowing the water to more fully absorb the heat generated during the mixing process and effectively preventing the water vapor generated by boiling from absorbing concentrated sulfuric acid and forming acid mist that escapes. The partition 6 is fitted with a water supply pipe 2, a concentrated sulfuric acid input pipe 3, and a balancer 4.

The partition 6 is also movably connected to a stirring shaft 7 that is evenly distributed around the concentrated sulfuric acid storage tank 9 via bearings. The stirring shaft 7 is fitted with evenly distributed stirring impellers 8. When the stirring shaft 7 is working, it can drive the stirring impellers 8 to rotate and stir in the dilution tank 1, thereby promoting the rapid mixing of water with the concentrated sulfuric acid output from the concentrated sulfuric acid storage tank 9, ensuring dilution efficiency, and effectively preventing local overheating, thus ensuring safety during the dilution process.

The opening and closing assembly is connected between the concentrated sulfuric acid storage tank 9, and can be opened when the concentrated sulfuric acid storage tank 9 outputs the concentrated sulfuric acid, so that the concentrated sulfuric acid can flow out smoothly through the concentrated sulfuric acid output channel 20, and can also be stirred in cooperation with the stirring shaft rod 7 and the stirring impeller 8, so as to further strengthen the stirring and mixing effect in the dilution process. In addition, during the process of supplementing the concentrated sulfuric acid into the concentrated sulfuric acid storage tank 9 by the concentrated sulfuric acid input pipe 3, the opening and closing assembly can also keep closed to close the concentrated sulfuric acid output channel 20, so as to ensure the storage effect of the concentrated sulfuric acid storage tank 9 on the concentrated sulfuric acid.

The outside of the closure plate 19 and the extension edge 26 are fixedly connected with the uniformly distributed reinforcing ribs, the outside of the extension edge 26 is provided with the second deformation zone 27, the thickness value and the width value of the second deformation zone 27 are smaller than those of other regions of the extension edge 26, in the process that the concentrated sulfuric acid storage tank 9 outputs the concentrated sulfuric acid into the dilution tank 1 through the concentrated sulfuric acid output channel 20, the closure plate 19 is in an open state, the synchronous stirring shaft rod 7 drives the stirring impeller 8 to rotate, promotes the mixing of the concentrated sulfuric acid and the water flow in the dilution tank 1, the stirring shaft rod 7 drives the abutting plate 28 to rotate synchronously in the process of rotation, and then the abutting plate 28 contacts the end of the extension edge 26 outside the closure plate 19, the abutting plate 28 abuts against the extension edge 26 after contacting the extension edge 26, and then the extension edge 26 drives the closure plate 19 to intensify the deformation at the first deformation zone 25, and at the same time, the extension edge 26 is also bent and deformed at the second deformation zone 27, until the end of the abutting plate 28 is separated from the end of the second deformation zone 27, the closure plate 19 is reset under the action of the elastic force of itself, the abutting plate 28 repeatedly contacts and separates from the extension edge 26 with the rapid rotation of the stirring shaft rod 7, the closure plate 19 repeatedly generates displacement, disturbance is generated outside the concentrated sulfuric acid output channel 20, and the contact and mixing effect of the concentrated sulfuric acid output from the concentrated sulfuric acid output channel 20 and the water flow in the dilution tank 1 is further strengthened. In the process that the concentrated sulfuric acid storage tank 9 supplements the concentrated sulfuric acid through the concentrated sulfuric acid input pipe 3, the first rotating shaft rod 12, the second rotating shaft rod 13 and the threaded rod 23 are reversely rotated, and then the stirring shaft rod 7 and the stirring impeller 8 are also reversely rotated, when the concentrated sulfuric acid storage tank 9 is closed outside the concentrated sulfuric acid output channel 20, the abutting plate 28 also reversely extrudes the outside of the extension edge 26, extrudes the extension edge 26 and the closure plate 19 towards the outside of the concentrated sulfuric acid storage tank 9, and further improves the closure effect of the closure plate 19 on the concentrated sulfuric acid output channel 20.

[0050] In the embodiment, as shown in Figures 8 to 12As shown, the closing plate 19 is symmetrically connected with a connecting plate 33 on the side of the closing plate 19 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 with a flow stirring plate 31, the two sides of the flow stirring plate 31 are provided with guide surfaces 32, and the bottom of the concentrated sulfuric acid storage tank 9 is provided with a through groove 24 matching the size of the flow stirring plate 31. The repeated displacement of the closing plate 19 will cause the connecting plate 33 and the flow stirring plate 31 to be displaced synchronously in the process of generating disturbance outside the concentrated sulfuric acid output channel 20. The connecting plate 33 can form a partition between the two concentrated sulfuric acid output channels 20, further avoiding the mixing of concentrated sulfuric acid discharged from the two concentrated sulfuric acid output channels 20. The existence of the flow stirring plate 31 can increase the contact area between the closing plate 19 and the water flow, thereby making the flow disturbance effect generated in the reciprocating movement of the closing plate 19 stronger, and accelerating the dilution and mixing efficiency of the concentrated sulfuric acid. The through groove 24 is provided for storing the flow stirring plate 31 and the connecting plate 33 when the closing plate 19 is closed. The guide surface 32 is provided to make the end surface area of the flow stirring plate 31 on the side of the concentrated sulfuric acid storage tank 9 smaller than the inlet area of the through groove 24, so that the flow stirring plate 31 is easily put into the through groove 24.
