DETAILED DESCRIPTION

[0065] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0066] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0067] like Figure 1 FIG. 1 is a schematic diagram of a treatment device for deep treatment of industrial fluorine-containing wastewater provided by an embodiment of the present invention, comprising:

[0068] A processing shell, the processing shell comprising a semi-cylindrical shell 1 and a processing shell 2;

[0069] A collecting shell 3, wherein the collecting shell 3 is fixed on both sides of the processing shell 2;

[0070] A material discharge chute 4, wherein the material discharge chute 4 is arranged on the collecting shell 3;

[0071] The side slope plates 6 are provided with two and symmetrically distributed, and the side slope plates 6 are in contact with the outer wall of the collecting shell 3. The filter part 5 is provided at the lower end of the filter part 5;

[0072] A first baffle plate 7, which is rotatably connected to the bottom of the slope plate 6 and abuts against the material discharge chute 4;

[0073] The slope plate 6 is connected to a first elastic support mechanism 200 that supports it;

[0074] The filter part 5 is connected to a limiting mechanism 400 for driving the filter part 5 to flip.

[0075] The first elastic support mechanism 200 is connected to an automatic feeding mechanism 300 , and a water distribution mechanism 100 is disposed in the semi-cylindrical shell 1 .

[0076] In the embodiment of the present invention, when in use, wastewater is transported through the water diversion mechanism 100 in the semi-cylindrical shell 1, and the wastewater enters the treatment shell 2. The slope plate 6 is driven to move downward by utilizing the potential energy of water, and the sewage is filtered through the filter part 5 and flows into the bottom. After the slope plate 6 drives the first elastic support mechanism 200 to move to a predetermined position, the slope plate 6 is driven to flip through the limit mechanism 400. The slope plate 6 flips until the slope plate 6 flips with the first elastic support mechanism 200 as the center, so that it flips to the lowest point of the slope plate 6 and is opposite to the feed chute 4, so that impurities on the slope plate 6 pass through the feed chute 4 along the surface of the slope plate 6 and enter the collection shell 3 to be collected. The first baffle 7 can have the effect of shielding the feed chute 4 when the filter part 5 filters the sewage. When the first elastic support mechanism 200 moves, the automatic feeding mechanism 300 feeds quantitatively, so that the sewage treatment agent is mixed with the sewage. It integrates filtration, impurity removal, and feeding, has complete functions and occupies a small area, and has a good treatment effect.

[0077] like Figure 1 As shown, as a preferred embodiment of the present invention, the water distribution mechanism 100 includes:

[0078] A first rotating shaft 8, which is rotatably disposed at the axis of the semi-cylindrical shell 1;

[0079] A water divider plate 9, the water divider plate 9 is evenly fixed on the first rotating shaft 8, and the water divider plate 9 slides in a sealed manner with the inner wall of the semi-cylindrical shell 1;

[0080] The water inlet pipe 10 is fixedly connected to the semi-cylindrical shell 1 and is located on one side of the axis of the semi-cylindrical shell 1 .

[0081] In the embodiment of the present invention, when in use, waste water falls from the water inlet pipe 10 and impacts the water diversion plate 9, so that the water diversion plate 9 drives the first rotating shaft 8 to rotate, and the water diversion plate 9 squeezes the slope plate 6 to move it downward.

[0082] like Figure 2 As shown, as another preferred embodiment of the present invention, the first elastic support mechanism 200 includes:

[0083] A fixing plate 11, wherein the fixing plate 11 is fixed in the processing housing 2;

[0089] In the embodiment of the present invention, when in use, due to the elastic force of the second elastic member 16, the slope plate 6 flips toward the middle with the connecting plate 15 and the rotating frame 14 as the center, and because the end faces of the two slope plates 6 are abutted, they cannot flip and thus move downward. The slope plate 6 squeezes the first elastic member 13 until the slope plate 6 is limited by the limiting mechanism 400, thereby overcoming the elastic force of the second elastic member 16 and flipping to the lowest point of the slope plate 6 opposite to the discharge chute 4, so that the impurities on the slope plate 6 pass through the discharge chute 4 along the surface of the slope plate 6 and enter the collection shell 3 to be collected.

When the extension rod 22 moves to contact the limit shell 23 and cannot move further, the slope plate 6 drives the connecting plate 15, the rotating frame 14 and the mounting plate 12 to continue to move, so that the top ball 21 abuts between the two slope plates 6, thereby driving the slope plate 6 to flip.
