Description

Technical Field

[0001] This utility model relates to the technical field of waste acid pretreatment tanks, specifically a waste acid pretreatment tank with turbulent flow disturbance. Background Technology

[0002] Waste acid is acidic waste liquid generated after industrial production or laboratory use. It mainly includes waste sulfuric acid and waste hydrochloric acid, among which waste sulfuric acid is the most common. It mainly comes from chemical reactions such as nitration, esterification, and sulfonation of organic matter, as well as industrial processes such as titanium dioxide production and steel pickling. Waste acid needs to be pretreated before it is disposed of. The main process is to put waste acid and neutralizing agent into a pretreatment tank for mixing.

[0003] The aforementioned device lacks a turbulence plate and gas-assisted turbulence mixing structure within the pretreatment tank. As a result, when mixing waste acid and neutralizing agent in existing treatment tanks, they are mostly directly added into the tank for natural mixing or stirred by stirring rollers. The mixing speed and effect are relatively average. Based on the shortcomings of existing technology, this utility model designs a waste acid pretreatment tank with turbulence disturbance.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

At this time, the drive motor is started to drive the transmission shaft to rotate the perforated pipe and the turbulent flow plate. The staggered turbulent flow plate rotates and stirs the waste acid and pretreatment agent in the main body of the treatment tank, generating turbulent flow and mixing them together.

The blades of the two sets of turbulence plates 204 on the left and right are arranged in opposite directions. The drive shaft 2 is fixedly connected to the bottom of the auxiliary air supply slip ring 305.

[0025] By setting a perforated pipe 203 and a turbulence plate 204, which are rotatably mounted inside the treatment tank body 1, the waste acid liquid and pretreatment agent inside the treatment tank body 1 are stirred and mixed. By setting a drive shaft 2 and a drive motor 201, the perforated pipe 203 and the turbulence plate 204 are driven to rotate. By setting a pipe joint 202, the perforated pipe 203 and the turbulence plate 204 are connected and fixed to the drive shaft 2. At the same time, air in the auxiliary mechanism 3 can be transported to the perforated pipe 203 through the pipe joint 202 and discharged, so that turbulence is further generated in the waste liquid to improve the mixing efficiency.

[0026] Please see Figure 4 - Figure 5 The auxiliary mechanism 3 includes a main air supply slip ring 301, a fixing frame 302, a first air supply connector 303, a first air supply pipe 304, a secondary air supply slip ring 305, a second air supply connector 306, a second air supply pipe 307, and a third air supply connector 308. The main air supply slip ring 301 is fixedly installed on the top cover 103. The fixing frame 302 is fixedly connected between the main air supply slip ring 301 and the top cover 103. The first air supply connector 303 is fixedly connected to the side wall of the fixing frame 302. One end of the first air supply pipe 304 is fixedly installed on the first air supply connector 303. The secondary air supply slip ring 305... 05 is rotatably mounted on the lower surface of the main air supply slip ring 301. The second air supply connector 306 is fixedly connected to the side wall of the auxiliary air supply slip ring 305. The second air supply pipe 307 is fixedly connected to the second air supply connector 306. The third air supply connector 308 is fixedly connected to the bottom end of the second air supply pipe 307. The main air supply slip ring 301 is connected to the auxiliary air supply slip ring 305.

[0027] By setting up a first air supply pipe 304, a first air supply connector 303, a second air supply connector 306, a second air supply pipe 307, and a third air supply connector 308, air in the air supply equipment is sent into the perforated pipe 203 for discharge. By setting up a main air supply slip ring 301 and an auxiliary air supply slip ring 305, the first air supply pipe 304 and the second air supply pipe 307 are connected. By setting the main air supply slip ring 301 and the auxiliary air supply slip ring 305 to be rotatably connected, and the auxiliary air supply slip ring 305 is fixedly connected to the drive shaft 2, so that when the drive shaft 2 rotates, the auxiliary air supply slip ring 305 can also rotate with it to prevent the two second air supply pipes 307 from rotating and getting tangled. At the same time, the auxiliary air supply slip ring 305 can also be continuously connected to the main air supply slip ring 301 to supply air.

[0028] Working principle: When the waste acid pretreatment tank with turbulent flow is used, in the initial state, the support feet 101 and the drain valve pipe 102 are first set at the bottom and side wall of the main body 1 of the treatment tank. The top cover 103 is closed on the top of the main body 1 of the treatment tank by the connecting bolt 104, and the top cover 103 is provided with a feeding port 105 that is sealed by the sealing cover 106, so as to facilitate the feeding and sealing of waste acid and pretreatment materials into the main body 1 of the treatment tank. The transmission shaft 2 rotatably connected inside the main body 1 is equipped with a pipe joint 202, a perforated pipe 203 and a turbulence plate 204. The drive shaft 2 is driven by the drive motor 201 at the bottom of the treatment tank body 1, so as to generate turbulence in the waste acid in the treatment tank body 1 and improve the mixing effect with the pretreatment agent. At the same time, a third gas supply connector 308 is installed on the pipe connector 202. The third gas supply connector 308 is connected to the auxiliary gas supply slip ring 305 through the second gas supply pipe 307 and the second gas supply connector 306. The auxiliary gas supply slip ring 305 is connected to the first gas supply pipe 304 through the main gas supply slip ring 301, so as to supply gas into the perforated pipe 203, so that the gas enters the waste liquid from the perforated pipe 203 to further accelerate the mixing effect of the waste liquid and the pretreatment agent.

[0029] When turbulent flow is needed to accelerate the mixing and pretreatment of waste acid, firstly, the sealing cap 106 is removed from the feed port 105. Then, the waste acid and pretreatment agent are added into the feed port 105. At this time, the drive motor 201 is started to drive the transmission shaft 2, which in turn drives the perforated pipe 203 and the turbulent flow plate 204 to rotate. The turbulent flow plate 204, which is staggered up and down, rotates and stirs the waste acid and pretreatment agent in the treatment tank body 1, generating turbulent flow and mixing them together. At the same time, the external gas supply equipment sends gas into the first gas supply pipe 304, through which... The first air supply connector 303, the main air supply slip ring 301, the auxiliary air supply slip ring 305, and the second air supply connector 306 deliver gas to the second air supply pipe 307. The gas in the second air supply pipe 307 is discharged from the round hole on the fixed frame 302 through the third air supply connector 308 and the fixed frame 302 and enters the waste acid in the main body of the treatment tank 1. The air entering the waste acid further causes the waste acid liquid to generate turbulence and accelerate the mixing with the pretreatment agent. This device is convenient for using turbulence to accelerate the mixing and pretreatment of waste acid.
