[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] A dosing device for sewage treatment, such as Figure 1 As shown, it includes a bracket 1, a control panel 2, a bracket 2, a water pipe 10, an escalator 13, a cable 18, and a sliding component. A first mounting groove is provided on one side of the bracket 1, and a second mounting groove is provided on the inner side of the bracket 2 3. The first mounting groove and the second mounting groove are in the same horizontal plane. The control panel is installed on the outer surface of the bracket 1. There are three water pipes 10, and the water pipes 10 are installed on the inner side of the bracket 1 through water pipe clamps. The cable 18 is installed on the inner side of the bracket 1 through a wire fixer. The escalator 13 is welded on the bracket 2 3, and the escalator 13 has several layers.

[0028] In this case, bracket 1 and bracket 2 3 provide support for the dosing device. Mounting grooves are set on the inner sides of bracket 1 and bracket 2 3 to facilitate the disassembly and installation of the dosing device, and also play a fixing role. The current status of the dosing device can be understood through the control panel 2, and the working status of the dosing device can be controlled through the control panel 2. The water pipe 10 can transport the liquid in the dosing device to the required place, and the cable 18 can connect multiple dosing devices together. The dosing and other functions are controlled through the control panel 2. The escalator 13 can assist workers in climbing the dosing device, which is convenient for adding powder to the dosing device.

[0029] like Figure 2 , Figure 5As shown, the sliding assembly includes a fixing device 15, a roller 19, and a slide rail 20. The slide rail 20 is installed in the groove of the bracket 1 and the bracket 2 3 by bolts. The slide rail 20 is an I-shaped structure. The fixing device 15 is slidably connected to the outer wall of the slide rail 20. The fixing device 15 is provided with an I-shaped groove and is used in conjunction with the slide rail 20. The roller 19 is installed on the raised part of the groove of the fixing device 15.

[0030] In this case, the fixture 15 moves on the bracket 1 and the bracket 2 3 via the slide rail 20, and the roller 19 assists the fixture 15 in moving, thereby reducing the physical strength required to move the dosing device.

[0031] like Figure 3 As shown, the dosing device also includes a medicine barrel 4, a medicine barrel 21, a medicine inlet 8, a DC motor 9, and a liquid level sensor 14. The medicine barrel 4 is welded to a fixture 15, and the fixture 15 is located on both sides of the medicine barrel. The medicine barrel 21 is located on the lower side of the medicine barrel 4. The medicine barrel 21 is welded to the medicine barrel 4, and the upper part of the medicine barrel 21 is retracted at a certain angle. The DC motor 9 is located at the top of the medicine barrel 4 and is connected to the medicine barrel 4 by bolts. The medicine inlet 8 is installed on the top of the medicine barrel 4. The liquid level sensor 14 is installed on the inner side of the top of the medicine barrel 4 by bolts, and the liquid level sensor 14 is electrically connected to the control panel 2.

[0032] In this case, medicine barrel 1 4 is combined with medicine barrel 2 21. When the medicine barrel is full of liquid medicine, since the upper part of medicine barrel 21 has a certain slope, all the liquid can be gathered at the bottom of medicine barrel 21 without causing waste. The liquid level sensor 1 can transmit data to the control panel 2 by detecting the liquid height in the barrel. The staff can understand the medication situation in the barrel through the control panel 2. By presetting the program in the control panel 2, water can be automatically added to the barrel and the medicine can be discharged in a quantitative manner.

[0033] like Figure 3 As shown, the dosing device also includes a stirrer 16 and a stirrer 2 17. The stirrer 16 is connected to the output end of the DC motor 9 through a coupling, and the input end of the stirrer 2 17 is welded to the output part of the stirrer 16.

[0034] In this case, two agitators are provided to fully mix the drug powder and water.

[0035] like Figure 1 , Figure 2 As shown, the dosing device also includes a water inlet 5, a drug outlet 6, and a sewage outlet 7. The water inlet 5 is installed on the left side of the bottom of the medicine barrel 21, the drug outlet 6 is installed in the center of the bottom outer side of the medicine barrel 21, and the sewage outlet 7 is set on the right side of the bottom of the medicine barrel 21.

[0036] In this case, water can be injected into the medicine barrel through the water inlet 5, the stirred medicine can be sent out through the medicine outlet 6, and the waste liquid that does not meet the requirements in the barrel can be discharged by setting the sewage outlet 7, so that the barrel can be cleaned without moving the dosing device.

[0037] like Figure 1 , Figure 2 As shown, the dosing device also includes a one-way valve 22, a water pump 11, and a metering pump 12. There are three one-way valves 22, which are respectively installed at the bottom of the water inlet 5, the drug outlet 6, and the sewage outlet 7. There are two water pumps 11, which are located below the water inlet 5 and the sewage outlet 7. The water pump 11 is connected to the one-way valve 22 through a concentric reducer, and the water inlet end of the metering pump 12 is connected to the one-way valve 22 through a concentric reducer. The water pump 11 and the metering pump 12 are connected to the water pipe 10.

[0038] By setting the water pump 11, water can be injected into the barrel and waste liquid in the barrel can be extracted. The metering pump 12 can deliver the stirred liquid medicine and control the amount of medicine output. The one-way valve 22 can prevent the occurrence of backflow.

[0039] Working principle: The worker installs the medicine barrel on the bracket 1 and the bracket 2 3 through the fixture 15, and pours the powder into the barrel through the medicine inlet 8 through the escalator 13. Different medicine mixing methods are selected through the control panel 2. A certain amount of clean water is injected through the water pump 11 and the water inlet 5. When the water is injected, the liquid level sensor detects the amount of water injected. When the required amount is reached, a signal is sent to the control panel 2 to control the water pump 11 to stop running. Then the control panel 2 starts the DC motor 9, and the DC motor 9 drives the stirrer 1 16 and the stirrer 2 17 to fully mix the powder with water. Then, the control panel 2 selects the appropriate amount of medicine to be injected through the metering pump 12 and the medicine outlet. The liquid is discharged from the outlet 6. When the medicine is discharged, the liquid level sensor 14 monitors the content in the barrel. When the discharge meets the requirement, a signal is sent to the control panel 2 through an electrical signal. The control panel 2 controls the metering pump to stop running, and the discharged medicine is sent to the sewage treatment tank through the water pipe 10. When the waste liquid in the dosing device needs to be discharged, the water pump 11 can be started through the control panel 2, and the waste liquid is discharged to the treatment area through the water pipe through the sewage outlet 7. The dosing device can be combined through the bracket 1 and the bracket 2 3. Multiple dosing devices can be assembled according to needs, connected through the water pipe 10 and the cable 18, and all the water pumps 11 and the metering pump 12 of the dosing device are controlled by the control panel 2.
