[0020] like Figure 1 As shown, this embodiment provides a gravity dosing device for medicine, including a medicine tank 2 with a detachable cover 1 on the top. The medicine tank is connected to a medicine inlet pipe 3 and a medicine outlet pipe 4. The opening of the medicine outlet pipe is higher than the opening of the medicine inlet pipe. The medicine inlet pipe is equipped with a pump body 5, a switch valve 6, and a flow meter 13. The medicine outlet pipe is equipped with a switch valve and a flow meter.
[0021] In this embodiment of the utility model, the lid is placed over the top opening of the medicine tank.
[0022] In this embodiment of the invention, the inlet of the liquid medicine inlet tube is located at the bottom of the liquid medicine tank.
[0023] In the embodiment of the utility model, the medicine liquid inlet pipe has one, the medicine liquid discharge pipe has two, and the two medicine liquid discharge pipes are oppositely arranged and have equal height of pipe orifice.
[0024] In the embodiment of the utility model, the bottom of the medicine liquid tank is provided with a supporting base 7, and the bottom surface of the medicine liquid tank is placed on the top surface of the supporting base.
[0025] In the embodiment of the utility model, the medicine liquid tank is installed inside the leakage-proof pool 8, the top of the leakage-proof pool is open and is provided with a detachable upper cover 9.
[0026] In the embodiment of the utility model, the inner circumferential wall and the inner bottom surface of the leakage-proof pool are both coated with a waterproof coating layer 10, and the medicine liquid tank is placed on the inner bottom of the leakage-proof pool through the supporting base.
[0027] In the embodiment of the utility model, the medicine liquid inlet pipe and the medicine liquid discharge pipe both pass through the hole in the circumferential wall of the leakage-proof pool to the outside.
[0028] In the embodiment of the utility model, the medicine liquid discharge pipe extends downward after passing through the hole in the circumferential wall of the leakage-proof pool to the outside.
[0029] In the embodiment of the utility model, the inner bottom of the leakage-proof pool is provided with a floor drain 11, and the floor drain is connected with a liquid discharge pipe 12.
[0030] In the embodiment of the utility model, the working principle of the medicament gravity dosing device is as follows: the medicament gravity dosing device is installed at the position of the end of the dosing point, a medicine liquid tank is arranged between the medicine liquid inlet pipe and the medicine liquid discharge pipe, the medicine liquid is first injected into the medicine liquid tank through the medicine liquid inlet pipe, when the liquid level of the medicine liquid in the medicine liquid tank gradually rises and reaches the pipe orifice of the medicine liquid discharge pipe, the medicine liquid will overflow into the medicine liquid discharge pipe and naturally flow downward by its own gravity, at this time, the opening and closing valve on the medicine liquid discharge pipe can be conveniently adjusted to a small flow value, and is suitable for small flow dosing.
[0031] Specific operation is as follows:
[0032] 1、the medicine liquid inlet pipe first injects the medicine liquid into the medicine liquid tank, when the liquid level of the medicine liquid in the medicine liquid tank gradually rises and reaches the pipe orifice of the medicine liquid discharge pipe, the medicine liquid will overflow into the medicine liquid discharge pipe and naturally flow downward by its own gravity, at this time, the opening and closing valve on the medicine liquid discharge pipe is adjusted to a predetermined small flow value for dosing the medicine liquid, and the opening and closing valve of the medicine liquid inlet pipe is also adjusted, so that the medicine liquid is added according to a predetermined addition value.
[0033] 2. Because a pump is installed on the inlet pipe, which pressurizes the liquid, the flow rate of the inlet pipe is not stable and will fluctuate within a certain range, sometimes high and sometimes low. Therefore, after determining and adjusting the flow rate, the liquid level inside the tank is observed, and the valve on the inlet pipe is fine-tuned to ensure that the lowest liquid level inside the tank is not lower than the lowest point of the outlet pipe and the highest liquid level is not higher than the top opening (preferably, the highest liquid level inside the tank should not be higher than the highest point of the outlet pipe). This buffering effect of the tank allows the internal liquid level to fluctuate between the adjusted lowest and highest levels over a longer period, adapting to the changing flow rate, while maintaining a stable flow rate.
[0034] 3. Staff should periodically open the box cover to check the liquid level and readjust the valve of the liquid inlet pipe as necessary to keep the liquid level within the required range.
[0035] 4. If the liquid discharge pipe is blocked or the device on the liquid inlet pipe malfunctions, causing the liquid to overflow from the liquid tank, the overflowing liquid will flow into the leak-proof pool and then flow back to the source of the liquid, such as the liquid storage tank, through the drain pipe.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
