[0026] Specifically, the inclined plate 22 and the bottom of the secondary filter plate 24 are both provided with a guide plate 27, and multiple groups of guide plates 27 are distributed at the connection between the secondary filter plate 24 and the tertiary filter plate 26, so as to realize the flow guide treatment of the wastewater.

[0027] As shown in Figures 1 to 5 , the filter hole size of the primary filter plate 21, the secondary filter plate 24 and the tertiary filter plate 26 gradually decreases, so as to effectively improve the filtering effect and improve the purification degree of the wastewater.

[0028] Further, the guide plate 27 is located at both sides of the filter hole of the secondary filter plate 24 and the tertiary filter plate 26.

[0029] It is worth noting that the guide plate 27 is provided in an "inclined structure".

The model is selected according to the actual use, so it will not be explained in detail.

[0033] Working principle and process: high-salt wastewater enters the filter tank from the top of the filter tank body 1, the wastewater first contacts the first filter plate 21, the first filter plate 21 preliminarily filters and intercepts larger impurity particles in the wastewater, removes larger suspended solids and other impurities, at this time, the inclined plate 22 plays a role in guiding the wastewater to flow to the first filter plate 21, so that the wastewater is more evenly distributed on the first filter plate 21 for filtration, the wastewater after the first filtration flows to the second filter plate 24 through the filter holes on the first filter plate 21 under the support of the connecting rod one 23. The second filter plate 24 further filters smaller impurity particles in the wastewater, because the filter hole size of the first filter plate 21, the second filter plate 24 and the third filter plate 26 gradually decreases, so the second filter plate 24 can intercept smaller impurities than the filter hole of the first filter plate 21. At the same time, the guide plate 27 at the bottom of the inclined plate 22 guides the wastewater after the first filtration to the second filter plate 24, so that the wastewater flows more smoothly to the second filter plate 24, the wastewater after the second filtration continues to flow to the third filter plate 26 through the filter holes of the second filter plate 24 under the support of the connecting rod two 25. The third filter plate 26 finely filters smaller particle impurities in the wastewater, further purifies the high-salt wastewater, the guide plate 27 at the bottom of the second filter plate 24 guides the wastewater after the second filtration to the third filter plate 26, and ensures that the wastewater is evenly distributed on the third filter plate 26 for filtration. Because the guide plate 27 is located on both sides of the filter holes of the second filter plate 24 and the third filter plate 26 and has an "inclined structure", it is beneficial to the flow guide treatment of the wastewater. The high-salt wastewater after the third filtration has been purified to a certain extent, and is discharged from the bottom of the filter tank body 1 for subsequent treatment or discharge operation;

[0034] When it is necessary to clean the impurities intercepted on the filter plate, the disassembly and cleaning assembly 3 is operated, the pull rod 35 is pulled, the second sawtooth plate 34 is slid in the groove on the surface of the mounting plate 31 under the action of the pull rod 35, the reset spring 36 is compressed, after the second sawtooth plate 34 is separated from the first sawtooth plate 32, the mounting plate 31 is taken out from between the clamping plates 33, the impurities on the inclined plate 22 can be cleaned, and the filter plates at all levels can also be cleaned. After cleaning is completed, the mounting plate 31 is clamped between the clamping plates 33 again, the pull rod 35 is loosened, and the second sawtooth plate 34 is clamped and fixed with the first sawtooth plate 32 again under the action of the reset spring 36.
