DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0020] The present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1:

[0022] The following is combined with Figure 1-2 The integrated sewage treatment equipment of this embodiment is described, comprising: a flocculation tank 1, wherein a plurality of water guide plates 2 are vertically and evenly connected to the inner wall of the flocculation tank 1, a gap is left between the water guide plates 2 and the opposite inner wall of the flocculation tank 1, and the gaps between adjacent water guide plates 2 are located at opposite ends. A sewage pipe 3 is connected to the head end of the flocculation tank 1, and a flocculant discharge pipe 4 is provided at the upper part of the head end of the flocculation tank 1. A plurality of spiral blades 5 are provided between adjacent water guide plates 2, and the spiral blades 5 are connected to a rotating shaft 6, which is rotatably connected to the bottom wall of the flocculation tank 1. All rotating shafts 6 have the same rotation direction, and the spiral blades 5 adjacent to each other along the water flow direction have opposite spiral directions. A sluice gate 7 is provided at the end of the flocculation tank 1, and the flocculation tank 1 is connected to the sedimentation tank 8 through the sluice gate 7;

[0023] The filtered sewage is injected into the flocculation tank 1 through the sewage pipe 3, and the flocculant is put into the sewage through the flocculant discharge pipe 4. The sewage and flocculant travel along the channel formed by the staggered water guide plates 2. The power of the rotating shaft 6 is turned on, and all the rotating shafts rotate in the same direction. Since the spiral directions of the spiral blades 5 adjacent to each other along the water flow direction are opposite, the rotating shaft 6 drives the spiral blades 5 to alternately move the flocculant and the sewage up and down, and fully contact with the impurities in the sewage, so that the subsequent flocculation effect is better. When the sewage fills the flocculation tank 1, the sluice gate 7 is opened, and the drainage speed of the sluice gate 7 is controlled to be consistent with the water injection speed. The flocculation tank 1 is kept full of water, leaving sufficient space for the flocculant to move. The terminal sewage is discharged into the sedimentation tank to start flocculation and sedimentation.

[0024] The sluice gate 7 includes a gate plate 71, which is sealed and hinged at the notch of the flocculation tank 1. A push rod 72 is connected to the upper surface of the gate plate 71. The push rod 72 is rotatably connected to the telescopic end of a hydraulic cylinder 73. The fixed end of the hydraulic cylinder 73 is rotatably connected to a hydraulic support 74. The hydraulic support 74 is connected to the side wall of the flocculation tank 1.

[0025] The extension and contraction of the extension end of the hydraulic cylinder 73 drives the push rod 72 to move, thereby controlling the opening and closing degree of the gate plate 71.

[0026] The sedimentation tank 8 includes a tank wall 81, and the flocculation tank 1 is connected to the middle of the tank wall 81. An overflow port 82 is provided on the upper part of the tank wall 81. The bottom of the tank wall 81 is connected to a flocculation discharge pipe 83. The flocculation discharge pipe 83 is evenly laid on the inner bottom wall of the tank wall 81 and has holes.

[0027] Since the flocculation tank 1 is connected to the middle of the tank wall 81, the liquid discharged from the middle of the flocculation tank 1 is buffered by the liquid below, and the sediment at the bottom will not be washed back.

[0028] The hole of the flocculent discharge pipe 83 is a flocculent discharge groove 84, and the flocculent discharge groove 84 is opened at the lower part of the flocculent discharge pipe 83 through the axis of the flocculent discharge pipe 83;

[0029] The lower half of the flocculent discharge pipe 83 is provided with a flocculent discharge groove 84, so that the sediment at the bottom and both sides of the flocculent discharge pipe 83 can enter the flocculent discharge pipe 83 without remaining.
