Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention.
Detailed Description
The invention is described in detail below with reference to the attached drawings and detailed description:
according to the automatic drip device for the automatic liquid injection machine, as shown in fig. 1, the automatic liquid injection machine comprises a liquid injection pump, the liquid injection pump comprises a liquid storage tank 5, 98% ethyl methyl carbonate liquid is stored in the liquid storage tank 5, a drip needle 8 is connected to a liquid outlet of the liquid storage tank 5, the drip needle 8 is aligned to a joint of a motor and a pump head of the liquid injection pump, and a drip electromagnetic valve 7 is arranged between the drip needle 8 and a liquid outlet of the liquid storage tank 5.
The 98% methyl ethyl carbonate liquid in the liquid storage tank is dripped to the joint of the motor and the pump head of the liquid injection pump by using the dripping needle head 8, so that the problem of electrolyte crystallization can be effectively solved. The device adopts the dropping solenoid valve 7 to control the dropping needle 8, can be integrally arranged in an automatic liquid injection machine or just put the dropping needle into the automatic liquid injection machine, and the normal work of the automatic liquid injection machine can not be influenced by controlling the dropping liquid through the automatic control system.
In this embodiment, the liquid storage tank 5 is filled with high-pressure gas, the liquid storage tank 5 is internally provided with a pressure sensor 1 for detecting the air pressure, and the inflation electromagnetic valve 3 inflates the liquid storage tank. The high-pressure gas can ensure the dropping effect, the pressure sensor 1 can detect the air pressure in the liquid storage tank 5, and when the air pressure is detected to be insufficient, the air inflation electromagnetic valve 3 can be opened in time through the control system to inflate the liquid storage tank 5 so as to maintain stable air pressure.
In this embodiment, the liquid storage tank 5 is provided with a liquid level column 4 for observing the liquid level in the liquid storage tank 5, a liquid level sensor 6 is arranged at the lowest set liquid level of the liquid storage tank 5, and the liquid storage tank 5 is provided with a liquid adding valve 2. The liquid level in the liquid storage tank 5 can be intuitively observed through the liquid level column 4, so that liquid can be conveniently and timely added into the liquid storage tank 5, the position of the liquid storage tank 5 is more convenient to set, and the problem that the position of the liquid storage tank 5 is inconvenient to observe the internal liquid level is avoided. The liquid level sensor 6 is arranged at the lowest set liquid level of the liquid storage tank 5, when the liquid level sensor 6 detects that the liquid level in the liquid storage tank 5 is lower than the lowest set value, alarm information can be sent to a control system to remind timely liquid adding, and the problem that the electrolyte crystallization cannot be solved due to poor liquid dropping effect caused by too low liquid level is avoided.
In this embodiment, there are a plurality of drip needles 8, each drip needle 8 corresponding to a connection of an infusion pump to a motor. One drip electromagnetic valve 7 can synchronously control a plurality of drip needles 8 to act simultaneously.
In this embodiment, the drip solenoid valve 7, the pressure sensor 1, the filling valve 2, the inflation solenoid valve 3, and the liquid level sensor 6 are all connected to the control device 9, and the data of the pressure sensor 1 and the liquid level sensor 6 are received and processed by the control device 9 to control the actions of the drip solenoid valve 7, the filling valve 2, and the inflation solenoid valve 3.
The drip method using the device is that the drip solenoid valve 7 is opened once every 20 to 30 minutes, each drip needle 8 drips 1 to 2 grams to the joint of the motor of the infusion pump and the pump head, and the drip time lasts for 3 to 5 seconds each time.
In practice, it is found that the problem of crystallization of electrolyte can be solved by dripping 98% methyl ethyl carbonate liquid to the joint of the motor and the pump head of the liquid injection pump every 30 to 50 minutes, but if the manual liquid dripping is performed without adopting the equipment, the operation can be performed only after the automatic liquid injection machine is stopped, the product quality is reduced due to the stoppage, the labor is wasted, and a certain potential safety hazard exists.
It is emphasized that: the above embodiments are merely preferred embodiments of the present invention, and the present invention is not limited in any way, and any simple modification, equivalent variation and modification made to the above embodiments according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
