[0025] See also Figure 1-4 The utility model provides a dosing device for treating domestic sewage, comprising a liquid medicine storage mechanism 10, a liquid medicine circulation mixing mechanism 20 and a stirring mixing mechanism 30.

[0026] The liquid medicine storage mechanism 10 is used to store the added water source and medicine. The liquid medicine circulation mixing mechanism 20 cooperates with the stirring mixing mechanism 30 to repeatedly mix the liquid medicine in the storage tank 110, thereby improving the mixing efficiency and mixing quality between the medicine and the water source.

[0027] See also Figure 1-Figure 3The liquid medicine storage mechanism 10 includes a storage tank 110, and a water inlet 120 and a medicine inlet 140 are respectively arranged on the top of the storage tank 110. A liquid outlet pipe 130 is arranged on one side of the storage tank 110, and a valve is arranged on the liquid outlet pipe 130. The liquid medicine circulation and mixing mechanism 20 includes a circulation pump 210, a liquid inlet pipe 220, a ring pipe 230 and a connecting pipe 250. The ring pipe 230 is fixed on the top side of the storage tank 110, and the lower part of the ring pipe 230 is provided with liquid outlet holes 240 distributed equidistantly. The liquid inlet of the circulation pump 210 is connected with the liquid inlet pipe 220, and the other end of the liquid inlet pipe 220 passes through the lower side wall of the storage tank 110 to the inside of the storage tank 110. The bottom end of the connecting pipe 250 is connected with the liquid outlet of the circulation pump 210, and the top end of the connecting pipe 250 passes through the outer wall of the storage tank 110 and is connected and docked with the ring pipe 230. The stirring and mixing mechanism 30 is installed inside the storage tank 110.

[0028] Clean water is added to the storage tank 110 from the water inlet 120, and then the medicine is added to the storage tank 110 through the medicine inlet 140. The stirring and mixing mechanism 30 mixes the medicine liquid inside the storage tank 110, and at the same time, the circulation pump 210 in the medicine liquid circulation mixing mechanism 20 extracts the medicine liquid at the bottom side of the storage tank 110 through the liquid inlet pipe 220, enters the inside of the ring pipe 230 through the connecting pipe 250, and finally disperses and discharges it from the liquid outlet 240 below the ring pipe 230 to the top of the liquid surface in the storage tank 110, so as to realize the rapid circulation and mixing of the solution below and above the storage tank 110, and has better mixing efficiency.

[0029] For specific settings, see Figure 1 and Figure 4 The storage tank 110 includes a tank body 111 and a tank cover 112, and the tank cover 112 is arranged on the top of the tank body 111. The stirring and mixing mechanism 30 includes a motor 310, a transmission shaft 320 and a stirring blade 330. The motor 310 is installed above the tank cover 112, and the output shaft end of the motor 310 rotates and passes through the tank cover 112. The top of the transmission shaft 320 is connected to the output shaft end of the motor 310 through a coupling, and the stirring blade 330 is installed on the outside of the bottom end of the transmission shaft 320. The motor 310 in the stirring and mixing mechanism 30 drives the transmission shaft 320 to rotate, and the rotating transmission shaft 320 drives the stirring blade 330 to rotate and mix the liquid medicine inside the storage tank 110.

[0030] Furthermore, a spiral blade 350 is fixedly disposed on the outside of the transmission shaft 320 above the stirring blade 330, and a barrel 360 is fixedly sleeved on the outside of the spiral blade 350. The cooperation between the barrel 360 and the spiral blade 350 can lift the solution on the bottom side of the storage tank 110 to the top of the barrel 360, that is, the liquid medicine inside the storage tank 110 is further quickly mixed.

[0031] Specifically, a sleeve 340 is fixedly sleeved on the outer side of the bottom end of the transmission shaft 320, and one end of the stirring blade 330 is fixedly connected to the outer wall of the sleeve 340 by welding.

[0032] In the above specific implementation, please refer to Figure 3 A fixing seat 270 is disposed outside the storage tank 110, and the circulation pump 210 is installed above the fixing seat 270. The liquid circulation mixing mechanism 20 also includes a filter cover 260, which is disposed at the liquid inlet end of the liquid inlet pipe 220, and the filter cover 260 prevents the drug particles inside the storage tank 110 from entering the circulation pump 210.

[0033] For further information, see Figure 1 and Figure 2 A moving wheel 150 is installed at the bottom of the storage tank 110, and a push handle 160 is arranged on the outside of the storage tank 110. The arrangement of the push handle 160 and the moving wheel 150 facilitates the transfer of the entire device.

[0034] It should be noted that the specific model specifications of the circulation pump 210 and the motor 310 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail. The power supply and principle of the circulation pump 210 and the motor 310 are clear to those skilled in the art and will not be described in detail here.

[0035] The working principle of the domestic sewage treatment dosing device is as follows: when in use, clean water is added to the storage tank 110 from the water inlet 120, and then the agent is added to the storage tank 110 through the dosing port 140. The stirring and mixing mechanism 30 mixes the liquid medicine inside the storage tank 110, and at the same time, the circulating pump 210 in the liquid medicine circulation mixing mechanism 20 extracts the liquid medicine at the bottom side of the storage tank 110 through the liquid inlet pipe 220, enters the ring pipe 230 through the connecting pipe 250, and finally disperses and discharges from the liquid outlet 240 below the ring pipe 230 to the top of the liquid surface in the storage tank 110, so as to realize the rapid circulation and mixing of the solution below and above the storage tank 110, and has better mixing efficiency.
