[0030] Example 1

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A premixing and pre-inspection device for a comprehensive chemical wastewater treatment plant includes a buffer tank 1, with several inlet pipes 2 distributed on the surface of the buffer tank 1, and the buffer tank 1 is connected to various branch pipes through the several inlet pipes 2.

[0032] A water outlet pipe 3 is connected to the surface of the buffer pool 1, and an observation box 4 is connected to the outlet of the water outlet pipe 3. A temperature sensor 5 is connected to the inner wall of the observation box 4.

[0033] An electric diversion valve 7 is connected to the outlet of the observation box 4, and a control module 6 is connected to the surface of the observation box 4.

[0034] The inner wall of the buffer tank 1 is connected to a premixing mechanism 8, which allows the sewage from each branch pipe to enter the buffer tank 1 for premixing before entering the large collection tank. This allows for observation of any abnormal reactions after mixing, such as color reactions or exothermic reactions. On the one hand, it helps to understand the abnormal operating conditions of the sewage source, and on the other hand, it allows for timely diversion of the problematic water flow to the emergency tank after an abnormality is detected, thus avoiding increased subsequent treatment costs.

[0035] Preferably, the observation box 4 is made of transparent glass, which facilitates the observation of the mixed reaction.

[0036] Preferably, the temperature sensor 5 is electrically connected to the control module 6, and the control module 6 is electrically connected to the electric diverter valve 7, which facilitates the control of the electric diverter valve 7 to open and close.

[0037] It should be noted that the control circuit can be implemented by those skilled in the art through simple programming, so it will not be described in detail here.

[0038] Example 2

[0039] Based on Example 1, a preferred embodiment of the premixing and pre-inspection device for a comprehensive chemical wastewater treatment plant provided by this utility model is available for reference. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: The premixing mechanism 8 includes: a fixed frame 801, which is fixed to the inner wall of the buffer tank 1. A drive motor 802 is connected to the top of the fixed frame 801. The output shaft of the drive motor 802 passes through the fixed frame 801 and is connected to a drive shaft 803. A first stirring blade 804 is connected to the bottom of the drive shaft 803. A drive gear 805 is connected to the surface of the drive shaft 803. A driven shaft 806 is connected to the bottom of the fixed frame 801. A driven gear 807 is connected to the surface of the driven shaft 806. A second stirring blade 808 is connected to the bottom of the driven shaft 806. Through the arrangement of the fixed frame 801, drive motor 802, drive shaft 803, first stirring blade 804, drive gear 805, driven shaft 806, driven gear 807, and second stirring blade 808, the multi-stage mixing function is realized, thereby improving the mixing efficiency and solving the problem of slow mixing efficiency.

[0040] Preferably, the fixing frame 801 is arranged in a "*" shape, and the driven shaft 806 is rotatably connected to the fixing frame 801, which facilitates effective support through the fixing frame 801.

[0041] Preferably, the driving gear 805 meshes with the driven gear 807, and the driven gear 807 is distributed at equal angles along the axial center line of the driving gear 805, which facilitates the driving gear 805 to drive the driven gear 807 to rotate synchronously.

[0042] Preferably, the size of the driving gear 805 is larger than that of the driven gear 807, which is beneficial to generate a speed difference between the driven gear 807 and the driving gear 805, thereby generating a speed difference between the first stirring blade 804 and the second stirring blade 808, and then generating turbulence through the speed difference, which significantly improves the mixing efficiency.

[0043] Preferably, there is a gap between the second stirring blade 808 and the first stirring blade 804, and the second stirring blade 808 corresponds to the position of the water outlet pipe 3 and several water inlet pipes 2, so that the water can be mixed when each branch pipe is filled and drained.

[0044] The usage process of the premixing and pre-inspection device for a comprehensive chemical wastewater treatment plant provided by this utility model is as follows: First, the buffer tank 1 is connected to each straight pipe through the inlet pipe 2, so that the wastewater is transported into the interior of the buffer tank 1. Then, the drive motor 802 is connected to the power supply and started, so that the drive motor 802 drives the drive shaft 803 to rotate, and the drive shaft 803 drives the first stirring blade 804 to rotate. At the same time, the drive shaft 803 drives several driven gears 807 to accelerate rotation through the drive gear 805, so that the driven gears 807 drive several second stirring blades 808 to accelerate rotation through the driven shaft 806. Thus, through the speed difference between the second stirring blades 808 and the first stirring blades 804, turbulence is generated when the wastewater flows towards the center inside the buffer tank 1, thereby accelerating the mixing efficiency.

[0045] The mixed wastewater is discharged through the outlet pipe 3 into the observation box 4. The observation box 4 allows for the observation of any abnormal mixing conditions, and the temperature sensor 5 is used to detect colorimetric / exothermic reactions. When an abnormality is detected, the control module 6 activates the electric diversion valve 7, which then transports the abnormal wastewater to the emergency pool for treatment, thereby avoiding increased subsequent treatment costs.

[0046] It should be noted that in comprehensive chemical industrial parks, metallic iron ions are a relatively common low-toxicity component in wastewater. Iron ions can react with various organic substances to produce color-changing products with good stability, bright color, and high saturation. Color can be visible to the naked eye even at a concentration of parts per ten thousand. Wastewater is pre-mixed in buffer tank 1. Once abnormal color is detected, the source pipeline is promptly identified, and wastewater containing iron ions or another color-changing component is diverted to the emergency tank for separate pretreatment. Routine manual inspections are conducted.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
