[0017] See also Figure 1 to Figure 2, the present utility model provides a technical solution: a rapid COD digestion and condensation device, which includes a digestion and condensation box 1. A plurality of groups of exhaust slots 11 are opened at positions near the top of three sides of the digestion and condensation box 1. And a sleeve 2 is installed at the top of the digestion and condensation box 1. Support legs 12 are installed at positions near the four corners of the bottom end of the digestion and condensation box 1. The four support legs 12 can support the digestion and condensation box 1. A liquid injection port 21 is provided at the top of the sleeve 2. And a shunt pipe 22 is communicated and arranged at the bottom end of the sleeve 2. A through hole is opened at the position of the inner wall of the top end of the digestion and condensation box 1 near the shunt pipe 22. And one end of the shunt pipe 22 passes through the through hole and penetrates through the inner wall of the top end of the digestion and condensation box 1 and extends into the interior of the digestion and condensation box 1. Four branch pipes 23 are communicated and arranged at the position near the bottom end of the outer surface of the shunt pipe 22. And one end of each of the four branch pipes 23 is connected and communicated with the outer surface of a confluence pipe 24. The four branch pipes 23 are of equal size. And the four branch pipes 23 are all in a U-shaped arrangement. The four branch pipes 23 are centrally symmetrically arranged with the center point of the sleeve 2 as the center. A through slot is opened at the position of the inner wall of the bottom end of the digestion and condensation box 1 near the confluence pipe 24. And one end of the confluence pipe 24 passes through the through slot and penetrates through the inner wall of the bottom end of the digestion and condensation box 1. A drain pipe 25 is communicated and arranged at the bottom end of the confluence pipe 24. A control valve is arranged on the outer surface of the drain pipe 25. And one end of the drain pipe 25 is communicated with the COD detector body. A support rod 26 is installed at the top end of the confluence pipe 24. And the top end of the support rod 26 is installed with the bottom end of the shunt pipe 22. The setting of the support rod 26 can connect and support between the confluence pipe 24 and the shunt pipe 22, so as to avoid the shunt pipe 22 and the confluence pipe 24 from being in a suspended state. A motor 27 is installed on the back side of the digestion and condensation box 1. And the output end of the motor 27 is in transmission connection with a rotating shaft 28.

The arrangement of the four groups of branch tubes 23 can, on the one hand, perform a shunting operation on the solution, so that the solution can be dispersed into the inside of the four groups of branch tubes 23, and on the other hand, it can reduce the speed of the solution, so as to increase the time of the solution in the digestion condensation box 1. At the same time, the user can start the motor 27, so that under the operation of the motor 27, The rotating shaft 28 and the cooling fan 29 can rotate accordingly, so that the four groups of branch pipes 23 and the solutions inside the four groups of branch pipes 23 can be cooled and dissipated, and the heat can be dissipated through the several groups of exhaust slots 11 set on the three sides of the digestion and condensation box 1. Through the above-mentioned settings and operations, the solutions inside the four groups of branch pipes 23 can be digested and condensed, so that the solution inside the confluence pipe 24 is finally in a digestion and condensation state. At this time, the control valve set on the outer surface of the drain pipe 25 can be opened, so that the solution can flow into the COD detector body and perform corresponding detection.
