Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1: a medicine unloading hose 1 used for connecting to a medicine unloading port of a tank truck or a temporary water source interface to an inlet of a medicine unloading pump, and a pipeline inlet hose clamp 2 and a pipeline outlet hose clamp 14 used for fixing the hose and a hard pipe are respectively arranged outside the inlet of the medicine unloading hose 1 and the outlet of the medicine unloading hose 1. When the medicine discharging operation is carried out, the medicine is conveyed to the inlet of the medicine discharging pump from the medicine discharging pump or the temporary water source interface through the medicine discharging hose 1.
An inlet pipeline 3 of the electric diaphragm pump and an outlet pipeline 13 of the electric diaphragm pump are respectively arranged at the inlet to the outlet of the inner part of the pipeline of the medicine unloading hose 1. The inlet pipeline 3 of the electric diaphragm pump and the outlet pipeline 13 of the electric diaphragm pump are both hoses, the sectional area of the pipelines is 1/4-1/3 of the sectional area of the pipeline of the medicine discharging hose 1, and the outer wall of the pipelines is connected with the inner wall of the medicine discharging hose 1, so that the positions of the pipelines are fixed in the medicine discharging hose 1 and do not change along with the flowing of medicine liquid during medicine discharging. The distance between the inlet pipeline 3 of the electric diaphragm pump and the inlet of the medicine unloading hose 1 is about 20-30 centimeters, and the electric diaphragm pump is close to the inlet of the medicine unloading hose 1 as much as possible on the premise that the electric diaphragm pump does not influence the installation and fixation of the medicine unloading hose 1, so that the electric diaphragm pump is closer to medicines, and the water filling effect of the electric diaphragm pump is ensured. Similarly, the distance between the outlet pipeline 13 of the electric diaphragm pump and the outlet of the medicine unloading hose 1 is about 20-30 centimeters, and the electric diaphragm pump is close to the outlet of the medicine unloading hose 1 as much as possible on the premise that the installation and fixation of the medicine unloading hose 1 are not influenced, so that the electric diaphragm pump is closer to the inlet of the medicine unloading pump, and the water filling effect of the electric diaphragm pump is ensured. The inlet pipeline 3 of the electric diaphragm pump and the outlet pipeline 13 of the electric diaphragm pump penetrate out of the middle part of the medicine unloading hose 1 and are connected to the outer side of the medicine unloading pipeline.

The front end of the electric diaphragm pump outlet pipeline 13 is connected with a pump outlet four-way valve 11. By adjusting the valve position of the pump inlet three-way valve 4, the liquid medicine can flow out from the main working pipeline 5 or the bypass pipeline 12 or keep a closed state, and is emptied by matching with a medicine unloading hose.
And a working main pipeline 5 and a bypass pipeline 12 are connected between the pump inlet three-way valve 4 and the pump outlet four-way valve 11.
And an electric diaphragm pump 6 and a main pipeline emptying pipeline 8 are sequentially arranged on the working main pipeline 5.
A bypass line evacuation line 10 is mounted on the bypass line 12.
And a main pipeline emptying valve 7 is installed on the main pipeline emptying pipeline 8.
The bypass line evacuation line 10 is fitted with a bypass line evacuation valve 9.
The utility model discloses a theory of operation:
considering that the liquid level of the medicine of the tank car is relatively low under some conditions, or when the medicine discharging pipeline needs to be washed, a used temporary water source has no pressure and is low in position, air in the inlet pipeline of the medicine discharging pump cannot be completely exhausted by using static pressure, the medicine discharging pump cannot normally operate under the condition that the inlet pipeline is not full of water, and the medicine discharging purpose cannot be achieved. At the moment, after the medicine discharging hose 1 is installed in place, liquid medicine is arranged at the inlet of the medicine discharging hose 1 and the inlet pipeline 3 of the electric diaphragm pump, air which is not emptied is arranged at the outlet of the medicine discharging hose 1 and the outlet pipeline 13 of the electric diaphragm pump, and the medicine discharging hose is not in a full water state. The valve position of the pump inlet three-way valve 4 is adjusted to the communicated electric diaphragm pump inlet pipeline 3 and the working main pipeline 5, and the valve position of the pump outlet four-way valve 11 is adjusted to the communicated electric diaphragm pump outlet pipeline 13 and the working main pipeline 5. The electric diaphragm pump 6 is started, the electric diaphragm pump sends the liquid medicine to the outlet from the inlet of the medicine unloading hose 1, at the moment, because the outlet valve of the medicine unloading pump is in a closed state, the liquid medicine sent to the outlet extrudes the air originally accumulated at the position to the inlet of the medicine unloading hose 1 and discharges the air to the outside of the system, the air in the medicine unloading hose 1 is observed to be completely discharged after the system is operated for a period of time, and the electric diaphragm pump 6 is stopped to be operated after the medicine unloading hose 1 is filled with water.
At this point, the unloading of the drug can begin. The valve position of the pump inlet three-way valve 4 is adjusted to be communicated with the electric diaphragm pump inlet pipeline 3 and the bypass pipeline 12, and the valve position of the pump outlet four-way valve 11 is adjusted to be communicated with the electric diaphragm pump outlet pipeline 13 and the bypass pipeline 12. The inlet pipeline 3 of the electric diaphragm pump and the outlet pipeline 13 of the electric diaphragm pump which are used for filling water in the previous step keep the flow direction of the medicine in the electric diaphragm pump consistent with that of the medicine unloading hose 1 when unloading the medicine, so that the flow area in the medicine unloading hose is not lost, and the normal operation of the medicine unloading pump is ensured.
After unloading the medicine and accomplishing, tank car unloads the medicine mouth and still exists the medicine to the pipeline of unloading the medicine pump entry, does not carry out the pipeline evacuation, and the valve position adjustment that will pump entry three-way valve 4 this moment is to the electronic diaphragm pump entry pipeline 3 of UNICOM and work trunk line 5, adjusts the valve position of pump exit cross valve 11 to the closed condition, opens work trunk line bleeder valve 7, places the distal end of work trunk line evacuation pipeline 8 at required discharge medicine point, like wastewater disposal basin, collecting vessel etc. Keeping the outlet valve of the medicine unloading pump open, starting the electric diaphragm pump 6, and sending the liquid medicine to the discharge pipeline 8 of the working main pipeline from the inlet pipeline 3 of the electric diaphragm pump and discharging the liquid medicine to the outside of the system side by side, thereby achieving the effect of emptying. The device avoids the risks that the residual medicines flow out to pollute equipment, the residual medicines are discharged everywhere and even harm is caused to people when the residual medicines in the pipeline are cleaned manually. After the liquid medicine is completely emptied, the medicine unloading hose 1 can be detached.
