Referring to fig. 6, when the geothermal water passes through the middle flow path 5, the geothermal water is filtered through a filter screen 7 inside the geothermal water to remove impurities such as sand and the like in the geothermal water;
and under the geothermal water impact of high pressure, in order to prevent 180 degrees upset of filter screen 7 from taking place, consequently, install first spring 16 for offset the impact force of rivers, and through the setting of circular slot 6, rivers are when passing filter screen 7, be located the circular slot 6 inner wall of circular slot 6 below, i.e. deposit ground 15, rivers can form backward flow in deposit ground 15 department, the rivers at its position are compared with the rivers velocity of flow at middle stream passageway 5 center less, consequently impurity part under the filtration can block in the filtration hole of filter screen 7, and another part can then be under the effect of gravity, filter screen 7 inclined plane guide and rivers and deposit gradually in deposit ground 15 department for concentrate the collection to impurity, so that follow-up cleanness.

the counteracting hole 8 communicates with the circular groove 6 and will strike the filter screen 7 when the ejector rod 9 extends into the circular groove 6.
Referring to fig. 6, it can be seen from the foregoing that the ejector rod 9 removes the water pressure from the elastic member, and moves into the circular groove 6 along with the water pressure, and impacts the filter screen 7;
because the two counteracting holes 8 are symmetrically arranged about the middle flow channel 5, when the middle flow channel 5 rotates to the vertical position in the rotating process of the separation disc 4, the two counteracting holes 8 are simultaneously communicated with the two water inlet channels 3 respectively, so that the filter screen 7 is possibly damaged because the two ejector rods 9 simultaneously extend into the circular grooves 6, and the purpose of arranging the rotating baffle 11 is to avoid that the two counteracting holes 8 are simultaneously communicated with the water inlet channels 3;
referring to fig. 6-9 specifically, during the rotation of the separation disc 4, the front section drives the rotation baffle 11 to rotate reversely against the separation disc 4 through the transmission assembly, so when the middle flow channel 5 in the separation disc 4 rotates to a vertical state, one of the counteracting holes 8 is blocked and sealed under the action of the rotation baffle 11, so that only one ejector rod 9 stretches into the circular groove 6 under the action of water pressure, namely, the locally enlarged part in fig. 6 does not damage the filter screen 7, and then when the separation disc 4 continues to rotate, the rear section of the separation disc 4 does not drive the rotation baffle 11 to rotate through the transmission assembly, so that the continuous rotation of the rotation baffle 11 is avoided to block the middle flow channel 5;
it should be noted that, after the rotation process is finished, the relative positions of the rotating baffle 11 and the separating disc 4 will not affect the middle flow channel 5, and see fig. 6.
In one preferred embodiment, the inner walls of the two water inlet channels 3 are provided with notch grooves, the fan impeller 14 is rotatably arranged in the notch grooves, and the fan impeller 14 is impacted to rotate when geothermal water in the water inlet channels 3 flows;

Referring to fig. 6 specifically, when the water inlet channel 3 is in a connected state, the flow of water flow inside the water inlet channel can impact the fan impeller 14 to rotate, and the flow rate of water flow in the water inlet channel 3 can be influenced due to the blocking condition of the filter screen 7, so that the blocking condition of the filter screen 7 and the condition of internal impurities can be judged by detecting the rotating state of the fan impeller 14 by the self-excitation assembly, and the driving assembly is controlled to drive the separation disc 4 to rotate and switch so as to clean the impurities.
In one of the preferred embodiments, the self-excitation assembly comprises two detecting blocks 21 arranged outside the wellhead device 1, the two detecting blocks 21 are respectively and coaxially fixed with the two fan impellers 14, a counting assembly 22 for respectively counting the rotation number of the detecting blocks 21 is arranged on the outer wall of the wellhead device 1, when the rotation number of the detecting blocks 21 exceeds a preset value, the counting assembly 22 controls the driving assembly to drive the separation disc 4 to rotate and switch, and the detecting blocks 21 detected by the counting assembly 22 are also switched accordingly.

in the third embodiment, basically the same manner as in the first embodiment is provided, and the difference is that, referring to fig. 12 specifically, the counting assembly 22 in the first embodiment is replaced by the rotation speed testing assembly 24 for testing the rotation speed of the detecting block 21, because when the filter screen 7 is blocked, the flow speed of the water in the water inlet channel 3 will also be correspondingly reduced, and therefore, when the rotation speed testing assembly 24 detects that the rotation speed of the detecting block 21 is reduced to the preset value, the rotation speed testing assembly 24 triggers the driving assembly to start, while in the second embodiment, the influence of the fan blade wheel 14 on the rotation speed testing assembly is the greatest, so that the embodiment is more suitable for more impurities and can be switched according to the blocking condition of the filter screen 7.
