[0002] With the acceleration of urbanization and the improvement of people's living standards, the central heating system, as an important part of urban infrastructure, has a direct relationship with the quality of life of residents and the energy efficiency of the city through its operating efficiency and stability. However, in the operation of the central heating water system, due to the influence of various factors such as water quality, pipe material and system operating conditions, the formation of scale has become a common problem. Scale attached to the inner wall of the pipe will not only reduce the heat transfer efficiency of the pipe and increase energy consumption, but also may cause pipe blockage, corrosion and other problems, and even cause system collapse in severe cases.
[0003] At present, the traditional anti-scaling treatment method is mostly manual dosing, that is, adding anti-scaling agents to the heating water regularly to prevent the formation of scale. However, this method has many shortcomings: on the one hand, it is difficult to accurately control the dosage of the agent during manual dosing, which can easily cause waste or insufficient agent, affecting the anti-scaling effect; on the other hand, manual dosing is cumbersome and labor-intensive, and is easily affected by human factors, and it is easy to add the agent in time, which further affects the stable operation of the system.

[0010] As a further solution of the utility model: the outer wall of the medicine tank at the top end is fixedly connected with a medicine inlet; the outer wall of the medicine tank at the bottom end is fixedly connected with a sewage outlet.
[0011] As a further solution of the utility model: a display window is provided on the circumferential outer wall of the medicine tank;
[0012] The circumferential outer wall of the medicine tank is fixedly connected with a drain port;
[0013] Valves are respectively arranged on the circumferential outer walls of the water drain port, the medicine inlet port and the sewage outlet.

[0017] As a further solution of the utility model: the right implementation component includes a fixed column fixedly connected to the inner wall of the bottom of the medicine tank, a sleeve sleeved on the outer wall of the fixed column, and a sieve plate fixedly connected to the circumferential outer wall of the sleeve.
[0018] As a further solution of the utility model: the inner wall of the groove is slidably connected with a sliding block, wherein the corresponding side surfaces of two sliding blocks are rotatably matched with the bottom end of the round rod through a rotating shaft, and the corresponding side surfaces of the other two sliding blocks are rotatably matched with the top end of the sleeve through a rotating shaft.
[0019] Compared with the prior art, the utility model provides an automatic dosing device, which has the following beneficial effects:
[0020] 1. The automatic dosing device is provided with an adjustment device so that the liquid inlet of the input pipe faces the water flow direction of the liquid adding pipe, the liquid outlet of the output pipe follows the water flow direction of the liquid adding pipe, and after a certain amount of medicine is put into the medicine tank through the medicine inlet, when in operation, the different pressure differences of two cross sections caused by the siphon principle formed by the input pipe and the output pipe with the upper and lower height difference are used, so that during the circulation of liquid through the liquid adding pipe, part of the water can flow into the medicine tank through the input pipe, mix with the medicine liquid, and then be quantitatively output from the output pipe back to the liquid adding pipe, thereby realizing the unpowered automatic dosing operation during the infusion process, and the dosage of the medicine can be accurately controlled.

[0021] 2. The automatic dosing device is provided with upper and lower self-moving parts. When the liquid is input into the medicine tank from the input pipe, it will be received by the cylinder below. As the amount of liquid in the cylinder increases, it will move downward along the outer wall of the guide column due to weight, and then the connecting rod will rotate in the opposite direction with the positioning column as the base point. As a result, the right implementation component will slowly move upward as the left water filling component moves downward, thereby stirring the liquid medicine gathered at the bottom of the medicine tank to prevent the precipitation of solid matter in the liquid medicine.
[0022] 3. For the automatic dosing device, when the amount of liquid in the cylinder gradually increases, the cylinder slowly moves downward until it abuts against the top surface of the fixed plate. At this time, the circular plate will protrude from the cylinder as the cylinder moves downward, thereby being able to completely push the liquid in the cylinder into the medicine tank. When the amount of liquid in the cylinder decreases and the overall weight is lighter, the specific gravity of the left water-filling component and the right implementation component are inconsistent, so the connecting rod will rotate in the opposite direction again with the positioning column as the base point, which will cause the left water-filling component to slowly move upward as the right implementation component moves downward, thereby further stirring the liquid medicine gathered at the bottom of the medicine tank. This structure can realize automatic mixing of the liquid input from the liquid filling pipe and the liquid medicine in the medicine tank, and can also prevent solid matter in the liquid medicine from settling at the bottom of the medicine tank during automatic dosing.

[0041] Preferably, the outer diameter of the circular plate 1002 matches the inner diameter of the cylinder 9;
[0042] Preferably, the cylinder 9 is located below the output port of the input pipe 8;
[0043] Further preferably, the inner wall of the groove 1402 is slidably connected with a sliding block, wherein the corresponding side surfaces of the two sliding blocks are rotatably matched with the bottom end of the round rod 901 through a rotating shaft;
