Description

Technical Field

[0001] This utility model belongs to the technical field of dosing devices, and relates to an automatic dosing device for sewage treatment equipment. Background Technology

[0002] Automatic dosing systems can adjust the dosage of chemicals in real time based on water quality parameters, ensuring uniform distribution and thus improving water quality stability and safety. For example, during pH adjustment, when the pH value deviates from the set range, the automatic dosing system will automatically activate, adding acid or alkali solutions to restore the pH value to the normal range. By precisely controlling the dosage, the automatic dosing system avoids waste, reduces manual intervention, and lowers the operating costs of wastewater treatment equipment.

[0003] Currently, when the pressure, temperature, viscosity, and other parameters of the fluid in the dosing pipeline are unstable, it can lead to large pressure fluctuations in the pipeline, causing damage to the pipeline and equipment. The metering pump also generates harmful pressure during start-up and shutdown, making the system unstable and resulting in inaccurate dosing dosages, thus affecting the dosing effect. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, this application provides an automatic dosing device for sewage treatment equipment.

[0005] The technical solution of this utility model is as follows:

[0006] An automatic dosing device for wastewater treatment equipment includes a dosing tank body. A tank cover is fitted on the top of the dosing tank body, and a stirring motor is installed on the tank cover. The stirring motor drives a main shaft, and the bottom end of the main shaft is connected to a stirring impeller that extends into the interior of the dosing tank body. A high-level sensor, a low-level sensor, and a feed pipe are arranged on the left side of the dosing tank body. A filter is connected to the right side of the dosing tank body through a discharge pipe. The filter is connected to a metering pump through a bend in the pipe. The metering pump is connected to a pulse damper through a longitudinal pipe. The pulse damper is connected to a tee connector through a bend in the pipe. The tee connector is connected to a sampling pipe and a dosing pipe.

[0007] In a preferred embodiment of this utility model, the feed pipe is equipped with a feed valve.

[0008] In a preferred embodiment of this utility model, the bucket lid is equipped with a safety valve.

[0009] As a preferred embodiment of this utility model, a discharge valve is provided between the dosing tank body and the filter.

[0010] In a preferred embodiment of this utility model: the dosing tank body is placed on the upper plane of the support plate, and the support plate is connected to the bend pipe through the support column.

[0011] In a preferred embodiment of this utility model, the dosing tube is equipped with a back pressure valve and a dosing valve, and the sampling tube is equipped with a sampling valve.

[0012] The beneficial effects of this utility model are:

[0013] The installed stirring motor drives the main shaft to rotate. The bottom end of the main shaft is connected to the stirring impeller and extends into the interior of the dosing tank, ensuring that the added chemical solution is fully mixed. The pulse damper is connected to a tee pipe joint via a bend, which connects the sampling pipe and the dosing pipe. The pulse damper controls the flow direction and speed of the fluid in the dosing pipe, ensuring uniform flow, reducing the impact of pressure fluctuations, and limiting the harmful pressure generated by the metering pump during start-up and shutdown, thus preventing damage to the pipes and equipment. This allows for accurate control of the chemical dosage in the wastewater treatment equipment, ensuring the effectiveness, convenience, and reliability of the automatic dosing device.
