Description

Technical Field

[0001] This utility model belongs to the field of concentrated sulfuric acid dilution and mixing technology, and more specifically, it relates to a concentrated sulfuric acid dilution and mixing device. Background Technology

[0002] Concentrated sulfuric acid is a strong mineral acid with high corrosiveness. At high concentrations, it has strong oxidizing properties, as well as dehydrating, highly corrosive, non-volatile, acidic, and hygroscopic properties. It is an important chemical raw material.

[0003] Based on the above, the inventors have discovered the following problems: Currently, some concentrated sulfuric acid dilution and mixing devices use a stirring rod to stir when diluting concentrated sulfuric acid. Concentrated sulfuric acid is highly corrosive and can easily damage the stirring rod, thus affecting the dilution effect. In addition, the stirring rod is usually fixed inside the device with bolts, which makes it inconvenient to replace it quickly.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a concentrated sulfuric acid dilution and mixing device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of this utility model's concentrated sulfuric acid dilution and mixing device are achieved by the following specific technical means:

[0006] A concentrated sulfuric acid dilution and mixing device includes a dilution tank, a tank cover mounted on the top of the tank cover, a set of injection pipes mounted on the top of the tank cover, a mounting frame mounted on the top of the mounting frame, a motor mounted on the top of the mounting frame, an output of the motor passing through the mounting frame and connected to a mounting block, a mounting groove formed at the bottom of the mounting block, a stirring rod disposed inside the mounting groove, a fixing component mounted inside the mounting block, a through hole formed at the top of the tank cover, one end of the stirring rod passing through the through hole to the other side, and a cooling component installed inside the dilution tank.

[0007] Furthermore, the fixing component includes a set of chambers opened inside the mounting block, a limiting plate is provided inside the chambers, a pull rod is installed on one side of the limiting plate, a spring is sleeved on the surface of the pull rod, one end of the pull rod passes through the mounting block and is connected to a handle, and a locking block is installed on the other side of the limiting plate.

[0008] Furthermore, the stirring rod has slots on both sides, which match the locking blocks.

[0009] Furthermore, an annular slider is installed at the bottom of the mounting block, an annular groove is provided at the top of the can lid, the annular slider matches the annular groove, and several ball bearings are installed at the bottom of the annular slider.

[0010] Furthermore, the cooling assembly includes a cooling chamber located inside the dilution tank, with a cooling pipe spirally installed inside the cooling chamber. One end of the cooling pipe passes through the dilution tank and is connected to a water inlet pipe, while the other end of the cooling pipe passes through the dilution tank and is connected to a water outlet pipe.

[0011] Furthermore, a connecting plate is installed on one side of both the dilution tank and the tank cover. A threaded hole is opened through the surface of the connecting plate, and a bolt is installed inside the threaded hole.

[0012] Furthermore, a discharge pipe is installed at the bottom of the dilution tank, and a valve is installed on the discharge pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By using the handle, pull rod, spring, and locking block in combination, when the stirring rod needs to be replaced, the bolt is removed from the threaded hole, allowing the tank lid to be removed. Then, by pulling the pull rod outward with the handle, the locking block disengages from the slot, allowing the stirring rod to be pulled out and replaced. When installing the stirring rod, by pulling the pull rod outward with the handle, the pull rod moves the limiting plate and compresses the spring, inserting one end of the stirring rod into the installation slot through the through hole. Then, by releasing the pull rod, the spring rebounds and pushes the locking block into the slot, at which point the stirring rod is fixed, allowing for quick and easy replacement of the stirring rod. The operation is convenient and fast, improving work efficiency.

[0015] 2. By using the inlet pipe, outlet pipe, and cooling pipe, cooling water is added through the inlet pipe during the dilution process. The cooling water is transported through the cooling pipe and carries away the heat generated during the dilution of concentrated sulfuric acid. Then, the cooling water is discharged through the outlet pipe, which facilitates the cooling of the dilution tank and prevents damage to the dilution tank. Attached Figure Description

[0028] The fixing assembly includes a set of chambers 17 formed inside the mounting block 6. A limiting plate 18 is provided inside each chamber 17. A pull rod 19 is mounted on one side of the limiting plate 18, and a spring 20 is fitted onto the surface of the pull rod 19. One end of the pull rod 19 passes through the mounting block 6 and is connected to a handle 21. A locking block 22 is mounted on the other side of the limiting plate 18. Through the coordinated use of the handle 21, pull rod 19, spring 20, and locking block 22, when the stirring rod 10 needs to be replaced, the bolt 28 is removed from the threaded hole 27, thereby allowing the can lid 2 to be disassembled. Then, by pulling the lever 19 outward through the handle 21, when the locking block 22 disengages from the slot 23, the stirring rod 10 can be pulled out downward for replacement. When installing the stirring rod 10, by pulling the lever 19 outward through the handle 21, the lever 19 moves the limiting plate 18 and compresses the spring 20, inserting one end of the stirring rod 10 into the mounting slot 15 through the through hole 16. Then, by releasing the lever 19, the spring 20 rebounds and pushes the locking block 22 into the slot 23, at which point the stirring rod 10 is fixed, thus enabling quick replacement of the stirring rod 10. The operation is convenient and fast, improving work efficiency.

Add water and concentrated sulfuric acid to the dilution tank 1 through a set of injection pipes 3. Then start the motor 5. The motor 5 drives the mounting block 6 to rotate, which in turn drives the stirring rod 10. The stirring rod 10 stirs and dilutes the liquid inside the dilution tank 1. During the dilution process, cooling water is added through the water inlet pipe 8. The cooling water is transported through the cooling pipe 12 and carries away the heat generated during the dilution of the concentrated sulfuric acid. Then, the cooling water is discharged through the water outlet pipe 9 to cool the dilution tank 1 and prevent damage. After dilution is complete, open the valve 14 to drain the liquid. When the stirring rod 10 needs to be replaced... Bolt 28 is removed from threaded hole 27, allowing can lid 2 to be removed. Then, pull lever 19 outward using handle 21. When locking block 22 disengages from slot 23, stirring rod 10 can be pulled out and replaced. To install stirring rod 10, pull lever 19 outward using handle 21. Lever 19 moves limiting plate 18 and compresses spring 20. Insert one end of stirring rod 10 into mounting slot 15 through through hole 16. Then, release lever 19. Spring 20 rebounds and pushes locking block 22 into slot 23. Stirring rod 10 is then fixed, allowing for quick replacement of stirring rod 10. The operation is convenient and fast, improving work efficiency.
