Description
Technical Field
The utility model relates to the field of filling of conductive liquid containing particles, in particular to a device for directly controlling the flow rate of the conductive liquid containing particles by adopting electromagnetic force.
Background
In the liquid filling process, it is often necessary to reduce the flow rate of the liquid to reduce or avoid foaming, splashing, etc. of the liquid during the filling process.
To reduce the liquid flow rate, there are generally two methods:
1. reducing the pressure difference between the front and the rear of the filling valve. However, this method is limited by the mechanical structure of the filling equipment, and the pressure difference cannot be reduced to a small value, so that the flow rate of the liquid cannot be completely reduced to the optimal speed.
2. The flow passage area is reduced. This method is well suited for liquids that do not contain solid particles. However, when the filled liquid contains solid particles, the reduction of the flow area will obstruct the passage of the solid particles and even block the whole flow channel, so that the filling operation cannot be performed.
Disclosure of Invention
The utility model aims to solve the problems in the prior art, and provides a device for directly controlling the flow rate of conductive liquid containing particles by adopting electromagnetic force.
The utility model comprises an insulating and magnetic-conducting valve body, wherein a channel for the flow of conductive liquid containing solid particles is arranged in the valve body, a permanent magnet or an electromagnet is arranged on the valve body, and the magnetic field direction of the magnet is perpendicular to the flow direction of the conductive liquid containing the solid particles; the outer wall of the valve body is connected with a positive electrode and a negative electrode which are arranged in a direction perpendicular to the magnet, one ends of the positive electrode and the negative electrode are in direct contact with the conductive liquid, and the other ends of the positive electrode and the negative electrode are connected to a direct current power supply.
When the direct current power is connected, current flows to the negative electrode through the positive electrode and the conductive liquid, and according to the left hand rule, a left electromagnetic force F is generated in the conductive liquid, and the magnitude of the electromagnetic force F can be calculated according to the following formula:
F＝B*I*L （N）
wherein:
b is the magnetic field strength (T)
I is the current magnitude (A)
L is the length of the energized conductor, here the distance between the positive and negative electrodes.
Further improved, the magnet adopts a permanent magnet, and the electromagnetic force is changed by changing the current, so that the speed of the conductive liquid is changed.
Further improved, the magnet adopts an electromagnet, and the electromagnetic force is changed by changing the magnitude of the current or the magnetic field strength, so that the speed of the conductive liquid is changed.
The utility model has the beneficial effects that:
1. the valve body is made of insulating and magnetic conductive materials, a permanent magnet or an electromagnet is arranged on the valve body, the magnetic field direction is perpendicular to the flowing direction of the liquid, and a positive electrode and a negative electrode are arranged in the directions perpendicular to the magnetic field direction and the flowing direction of the liquid. When the electrode is connected with a direct current power supply, current flows from the positive electrode to the negative electrode through the conductive liquid, and the conductive liquid generates electromagnetic force opposite to the flowing direction of the conductive liquid, so that the flow speed of the conductive liquid is reduced.
2. The flow channel is smooth, and no convex parts are needed, so that solid particles can pass smoothly.
3. The magnitude of the electromagnetic force can be controlled by changing the magnitude of the current or the magnitude of the magnetic field strength, so that the flow rate of the liquid can be easily controlled.
