Description

Technical Field

[0001] This utility model relates to the field of liquid alkali dilution technology, specifically a mixing device for liquid alkali dilution. Background Technology

[0002] The dilution and mixing of liquid alkali (such as sodium hydroxide solution) is a fundamental process in chemical production, and its mixing efficiency and uniformity directly affect the quality of subsequent products.

[0003] Traditional dilution methods involve directly mixing water and liquid alkali in a container, which is inefficient, generates a lot of heat, has a large concentration deviation, low safety factor, and low degree of automation. Existing mixing devices use fixed-installation stirring racks for mixing, which can easily affect the mixing efficiency. At the same time, since the liquid alkali dilution process involves heat treatment, the existing technology simply uses room temperature cooling, which affects the processing efficiency. Therefore, it is necessary to improve the mixing device for liquid alkali dilution to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the present invention provides a mixing device for diluting liquid alkali, which has the following beneficial effects:

[0014] This liquid alkali dilution mixing device, through its efficient mixing and feeding mechanism, utilizes a motor to rotate the first bevel gear during operation.

[0026] Example 1:

[0027] Given that existing mixing devices using fixed-mounted stirring racks can easily lead to reduced mixing efficiency, this embodiment provides a mixing device for diluting liquid alkali. Please refer to [link / reference needed]. Figure 1-5 This utility model provides a technical solution: a mixing device for diluting liquid alkali, including a mixing tank 1 and a storage tank 2.

[0028] The high-efficiency mixing and feeding mechanism 9 includes a stirring component 91 and a mixing and cleaning component 92, with the mixing and cleaning component 92 disposed inside the stirring component 91.

[0030] Furthermore, the gear post 917 meshes with the gear plate 918, and the second bevel gear 915 meshes with the first bevel gear 913, which facilitates a more stable mixing process.

[0031] Furthermore, the mixing and cleaning assembly 92 includes a stirring frame 921, which is rotatably connected inside the connecting plate 914. A third bevel gear 922 is fixedly connected to the outside of the stirring frame 921. An impeller 923 is fixedly connected to the bottom of the stirring frame 921. A connecting box 924 is fixedly connected to the outside of the stirring frame 921. A first spring 926 is fixedly connected inside the connecting box 924. A scraper 925 is fixedly connected to the end of the first spring 926 away from the connecting box 924. This facilitates the simultaneous rotation of the stirring frame 921 and the stirring roller 916 in opposite directions, while ensuring that the scraper 925 always adheres to the inner wall of the mixing tank 1 for scraping, thus preventing the raw materials from adhering.

[0032] Furthermore, the third bevel gear 922 meshes with the first bevel gear 913, the scraper 925 is slidably connected to the connecting box 924, and the scraper 925 contacts the mixing tank 1, which facilitates a more stable dilution process.

[0033] Example 2:

[0034] Based on Example 1, the prior art suffers from heat release during the dilution of liquid alkali, and the existing technology simply uses room temperature cooling, which affects processing efficiency. Therefore, this utility model provides Example 2 to solve the above-mentioned technical problems. Please refer to Example 2. Figure 6 Furthermore, in conjunction with Embodiment 1, the heat dissipation and filtration mechanism 10 includes a connecting frame 101, which is fixedly connected to the bottom of the heat dissipation fan 7. A filter plate 102 is slidably connected inside the connecting frame 101. A fixing block 103 is fixedly connected to the front of the filter plate 102.

A sliding plate 106 is fixedly connected to the bottom of the second spring 105. A locking post 107 is fixedly connected to the bottom of the sliding plate 106, which facilitates the adjustment of the position of the locking post 107, thereby satisfying the installation and disassembly of the filter plate 102 and the heat dissipation fan 7, satisfying the air intake filtration process, and facilitating subsequent cleaning by the staff.

[0035] Furthermore, the slide plate 106 is slidably connected to the limiting box 104, the locking post 107 is slidably connected to the limiting box 104, and the fixing block 103 and the locking post 107 are respectively provided with grooves, and the locking post 107 is inserted into the groove, which makes the filtration process more stable.

[0036] In actual operation, when this device is used, all structures in contact with the liquid alkali and pure water raw materials are treated with corrosion resistance and rust prevention. Simultaneously, a fixed air duct is installed on the inner wall of the mixing tank 1 corresponding to the air outlet frame 4 of the cooling fan 7. The operator stores the liquid alkali stock solution and pure water separately into two sets of storage tanks 2. The water pump 5, working in conjunction with the connecting pipe 6, introduces the liquid alkali stock solution and pure water into the mixing tank 1 to begin the dilution process. The motor 912 operates, causing the first bevel gear 913 to rotate, which, in conjunction with the second bevel gear 915, causes the connecting plate 914 to rotate inside the mixing tank 1, moving the gear column 917. This, in conjunction with the toothed plate 918, causes the gear column 917 to rotate, thereby causing the stirring roller 916 to move... The connecting plate 914 rotates internally, causing the first bevel gear 913 to rotate, which in turn, in conjunction with the third bevel gear 922, causes the stirring frame 921 to rotate, thereby causing the impeller 923 to rotate. In conjunction with the first spring 926, the scraper 925 moves. During the dilution process, the reaction releases heat, which is activated by the cooling fan 7. In conjunction with the air outlet frame 4, the heat dissipation process begins. The filter plate 102 filters the air intake of the cooling fan 7. When the filter plate 102 needs to be cleaned periodically, the operator pulls the sliding plate 106. The movement of the sliding plate 106, in conjunction with the second spring 105, causes the locking post 107 to move, which, in conjunction with the fixing block 103, limits the movement between the filter plate 102 and the cooling fan 7.
