Technical Field
[0001] This utility model relates to the field of hot-dip galvanized square and rectangular tube production technology, and in particular to a pneumatic mixing device for waste acid tanks. Background Technology
[0002] Waste acid is generated during the production of hot-dip galvanized square and rectangular tubes. The waste acid is discharged into an outdoor waste acid pool for regular storage.
[0003] Due to years of use, a thick sediment has formed at the bottom of the waste acid tank. If this continues, it will seriously affect the capacity of the waste acid tank and also greatly affect the subsequent maintenance of the waste acid tank. After a certain amount is stored, it will be pumped out for treatment. When pumping out waste acid, the sediment at the bottom is usually not completely removed. Over time, it will form a hard sediment that is even more difficult to pump out, and can only be cleaned manually, which is both dangerous and labor-intensive. Therefore, this utility model proposes a pneumatic mixing device for waste acid tanks. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution for a pneumatic mixing device for waste acid tanks: the pneumatic mixing device for waste acid tanks includes a waste acid tank 1, a tank cover plate 2 and a canopy 3 are provided at the upper end of the waste acid tank 1, a support frame 4 is provided on the inner side of the canopy 3, a manhole 5 is opened at the upper end of the tank cover plate 2, and a pneumatic mixing component 6 is provided at the upper end of the tank cover plate 2.
[0021] The pneumatic mixing assembly 6 includes a main air supply pipe 61, a secondary air supply pipe 62 connected to one side of the main air supply pipe 61, a solenoid valve 63 installed in the middle of the secondary air supply pipe 62, an extension pipe 64 connected to the bottom of the secondary air supply pipe 62, an aeration pipe 65 connected to the bottom of the extension pipe 64, and a through hole 66 opened at the upper end of the pool cover plate 2.
[0022] like Figure 1-4 As shown, the pool cover 2 is compatible with the waste acid pool 1. The pool cover 2 has a rectangular structure. The canopy 3 is connected to the waste acid pool 1 by a support frame 4. There are several sets of support frames 4 arranged in an array. The support frames 4 are connected to the waste acid pool 1 by bolts. The manhole 5 has a rectangular structure and extends through the pool cover 2 into the interior of the waste acid pool 1, which is conducive to the storage of waste acid. At the same time, the pool cover 2 and the canopy 3 prevent acid gas from volatilizing, which is more environmentally friendly.
[0023] like Figure 1-4 As shown, one end of the main ventilation pipe 61 is connected to the air supply pipe of the external air compressor room. There are several groups of auxiliary ventilation pipes 62 arranged in an array. All groups of auxiliary ventilation pipes 62 are connected to the main ventilation pipe 61. The number of solenoid valves 63 is the same as the number of auxiliary ventilation pipes 62. The solenoid valves 63 are electrically connected to the external controller. The number of extension pipes 64 is three times the number of auxiliary ventilation pipes 62. The extension pipes 64 are connected to the auxiliary ventilation pipes 62. The aeration pipes 65 are connected to the extension pipes 64, and the number of both is equal. The through hole 66 is a cylindrical structure. The through hole 66 penetrates the tank cover plate 2 and extends into the interior of the waste acid tank 1. The number of through holes 66 is equal to the number of extension pipes 64, and the two are compatible. Several groups of aeration holes are opened at the upper end of the aeration pipe 65, which is conducive to aeration of the bottom of the waste acid tank 1, stirring up the sediment at the bottom of the waste acid tank 1 and mixing it with the waste acid.
[0024] The working principle of this utility model is as follows: During the use of the device, the main ventilation pipe 61 is connected to the air supply pipeline of the external air compressor room. Before the waste acid needs to be removed, all solenoid valves 63 are opened by the controller to pour the gas into the interior of the aeration pipe 65. Aeration is carried out through the aeration holes, which stirs up the sediment at the bottom of the waste acid tank 1 and mixes it with the waste acid. When the waste acid is removed, the sediment is collected together with it, without the need for personnel to clean it.
[0025] It should be noted that, through the pneumatic mixing component 6, when waste acid needs to be extracted, by connecting the main ventilation pipe 61 to the external air compressor room air supply pipeline, all solenoid valves 63 are opened, allowing compressed gas to enter the auxiliary ventilation pipe 62 through the main ventilation pipe 61, then enter the extension pipe 64 and the aeration pipe 65, and finally aerate through the aeration holes, stirring up the sediment at the bottom of the waste acid tank 1 and mixing it with the waste acid. When the waste acid is extracted, the sediment is collected together, eliminating the need for personnel to clean it, avoiding dangerous operations, reducing labor intensity, and improving work efficiency.
[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
