Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a dosing device. Background Technology
[0002] Current wastewater treatment equipment is generally equipped with a dosing device to add chemicals for auxiliary treatment of wastewater. The existing dosing device includes a chemical tank, which is additionally equipped with a stirring motor and stirring blades. During use, the stirring motor drives the stirring blades to continuously stir the chemical solution in the tank to ensure that the chemical solution in the tank does not settle locally. This results in high power consumption of the dosing device in actual use, so it needs to be improved. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a dosing device that can effectively reduce power consumption during use.
[0004] A dosing device according to a first aspect of the present invention includes: a medicine tank; a medicine output mechanism, the medicine output mechanism including a medicine pump and an output pipe, the output pipe being connected to the medicine tank and the medicine pump, the medicine pump being able to cooperate with the output pipe to output the medicine in the medicine tank; and an aeration and stirring mechanism, the aeration and stirring mechanism including a first air supply pipe, one end of the first air supply pipe extending into the medicine tank, the first air supply pipe being able to deliver gas into the medicine tank to aerate and stir the medicine.
[0005] According to an embodiment of the present utility model, a dosing device has at least the following technical effects: the first air supply pipe can be connected to the compressed air equipment or blower used in the existing sewage treatment workshop. By using the first air supply pipe to transport gas to aerate and stir the liquid in the medicine tank, the uniformly stirred liquid is output to the outside through the output pipe via the delivery pump. Compared with the existing additional setting of stirring motor and stirring blades, it can effectively reduce power consumption and save energy. At the same time, it saves the purchase and installation costs of stirring motor and stirring blades, further saving costs.
[0006] According to some embodiments of this utility model, the first air supply pipe is a compressed air supply pipe, and a compressed air pressure reducing valve is installed on the first air supply pipe. The first air supply pipe can be connected to the compressed air equipment used in the existing sewage treatment workshop. The compressed air pressure reducing valve can control the pressure of the compressed air in the first air supply pipe, prevent the gas pressure delivered to the medicine tank by the first air supply pipe from being too high, and ensure the normal operation of aeration and mixing.
[0007] According to some embodiments of this utility model, an aeration pipe is connected to one end of the first air supply pipe inside the medicine tank, and the aeration pipe is provided with aeration holes. The medicine liquid inside the medicine tank is aerated and stirred through the aeration holes.
[0008] According to some embodiments of this utility model, the aeration pipe is horizontally arranged at the bottom of the medicine tank, and the aeration holes are evenly arranged at the bottom of the aeration pipe. This can improve the efficiency of aeration and stirring, and accelerate the mixing of the medicine solution.
[0009] According to some embodiments of this utility model, the drug delivery pump is a pneumatic diaphragm pump, which includes a gas inlet and a gas outlet. A second air supply pipe is connected to the gas inlet. Compressed air is supplied to the pneumatic diaphragm pump through the second air supply pipe, causing the pump to operate and thus complete the output of the liquid medicine from the medicine tank. The pneumatic diaphragm pump has the advantages of accurate output measurement and no need for electricity, further saving energy and reducing operating costs.
[0010] According to some embodiments of this utility model, one end of the second air supply pipe is connected to the pipe wall of the first air supply pipe, and a first valve is provided on the second air supply pipe. After opening the first valve, air can be supplied to the second air supply pipe through the first air supply pipe to drive the drug delivery pump, eliminating the need for a separate air supply pipeline. When the drug delivery pump is not needed, the first valve can be closed.
[0011] According to some embodiments of this utility model, the aeration and stirring mechanism further includes a third air supply pipe. One end of the third air supply pipe is connected to the gas outlet, and the other end extends into the medicine tank for aeration and stirring of the medicine liquid inside the medicine tank. Compressed gas discharged from the medicine delivery pump can be introduced into the medicine tank through the third air supply pipe to aerate and stir the medicine liquid, thereby saving compressed air and further conserving energy.
[0012] According to some embodiments of the present invention, the aeration and stirring mechanism further includes a third air supply pipe, the two ends of which are respectively connected to the pipe wall of the first air supply pipe and the gas outlet. A second valve is provided on the third air supply pipe. The third air supply pipe is located downstream of the first air supply pipe at the connection point of the first air supply pipe compared to the connection point of the second air supply pipe at the connection point of the first air supply pipe. A third valve is provided on the first air supply pipe, and the third valve is located between the connection point of the third air supply pipe at the connection point of the first air supply pipe and the connection point of the second air supply pipe at the connection point of the first air supply pipe. When only stirring of the liquid medicine in the medicine tank is needed, simply close the first and second valves and open the third valve to allow compressed gas from the first air supply pipe to directly enter the medicine tank for aeration and stirring. When it is necessary to deliver the liquid medicine to an external location, simply open the first and second valves and close the third valve to allow compressed gas from the first air supply pipe to enter the medicine delivery pump for delivery. At the same time, compressed air from the gas outlet of the medicine delivery pump is transmitted through the third air supply pipe to the first air supply pipe and enters the medicine tank to pulse-stir the liquid medicine, achieving the purpose of stirring and delivering the liquid medicine simultaneously, ensuring the uniformity of the delivered liquid medicine.
[0013] According to some embodiments of this utility model, a first check valve is provided on the third air supply pipe. The first check valve ensures that gas can only flow from the gas outlet to the third air supply pipe, preventing compressed gas from flowing back into the third air supply pipe and ensuring the normal operation of the drug delivery pump.
[0014] According to some embodiments of this utility model, a second check valve is provided on the first gas supply pipe, and the second check valve is located between the connection point of the third gas supply pipe and the connection point of the second gas supply pipe with the first gas supply pipe. The second check valve prevents compressed gas from flowing back from the third gas supply pipe to the second gas supply pipe, ensuring that the gas flowing out of the third gas supply pipe flows to the medicine tank through the first gas supply pipe.
[0015] According to some embodiments of this utility model, the medicine delivery pump includes an inlet and an outlet, and the output pipeline includes a first delivery pipe and a second delivery pipe. The first delivery pipe is connected at both ends to the medicine tank and the inlet, respectively, and the second delivery pipe is connected to the outlet.
