The piezoelectric elements 2 are attached to both ends of the.

In FIG. 1, a part of the stock solution that has flowed in the direction of the arrow is filtered while passing through the filtration membrane cylinder 3 (arrow) and flows out from the discharge port 6b (arrow).
【0012】この間にろ過膜筒3の内面にケーク層が生
成されるが、本発明のろ過モジュールは圧電素子を備え
ているので次の要領でこれらを作動すればよい。During this time, a cake layer is formed on the inner surface of the filtration membrane cylinder 3, but since the filtration module of the present invention is provided with a piezoelectric element, these may be operated in the following manner.
【0013】図3は本発明のろ過モジュールの圧電素子

0,10を介して交流電源11に接続する。FIG. 3 is a diagram showing the operating principle of the piezoelectric element of the filtration module of the present invention. The piezoelectric element 2 on the right side of the drawing is connected to the lead wire 1.
It is connected to the AC power supply 11 via 0 and 10.

ことで、振動を吸収する。When the piezoelectric element 2 on the right side of the drawing is energized and its vibration is started, the traveling wave 12 of vibration advances in the direction of the arrow. At this time, the piezoelectric element 2 on the left side of the drawing absorbs the traveling wave 12.
More specifically, the piezoelectric element 2 on the left side of the drawing vibrates, converts kinetic energy into electric energy, and radiates heat to the surroundings, thereby absorbing the vibration.

徴がある。FIG. 4 is a diagram showing the operating principle of the comparative example. When the piezoelectric element 2 is provided only at one end, the traveling wave 12 collides with the wall of the socket 6 and returns as a reflected wave 14. The reflected wave 14 may cancel the traveling wave 12 to reduce the vibration width. Therefore, the present invention is characterized in that two piezoelectric elements 2 and 2 are provided in order to eliminate the influence of the reflected wave 14.

However, the piezoelectric elements 2 and 2 are easy to attach, and especially the piezoelectric elements 2 and 2 are
It is convenient because it is easy to maintain, inspect, and replace.
