Embodiment 1

[0038] refer to figure 1 with figure 2 , is a high-efficiency deflocculation machine disclosed in the present invention, comprising a vertically placed cylindrical deflocculation machine body 1, a vertically arranged stirring paddle 2 that is rotatably connected in the deflocculation machine body 1, and an The upper end of the main body 1 is used to drive the driving assembly 3 to rotate the stirring paddle 2 .

[0039] The body 1 of the deflocculating machine includes a cylinder 11, an agitator 12 fixed to the lower end of the cylinder 11 through a flange, and a bottom plate 13 fixed on the end of the agitator 12 away from the cylinder 11 by bolts, and fixed on the outer wall of the agitator 12 There is an inlet pipe 121 and an outlet pipe 122 communicating with the agitator 12. The inlet pipe 121 and the outlet pipe 122 are respectively located on both symmetrical sides of the agitator 12 and their axes coincide, which can reduce the overall height of the deflocculating ma...

Embodiment 2

[0045] refer to image 3 The difference between this embodiment and Embodiment 1 is that the shearing plate 4 is detachably connected inside the agitator 12 through the connecting assembly 5, and the connecting assembly 5 includes an upper mounting ring 51 detachably connected to one end of the shearing plate 4 and The lower mounting ring 52 that is detachably connected to the end of the shearing plate 4 away from the upper mounting ring 51, wherein the upper mounting ring 51 and the lower mounting ring 52 are plugged with the inner wall of the agitator 12, and a fixed shearing ring is provided inside the agitator 12. Positioning assembly 6 for the position of the plate 4 in the stirrer 12 .

[0046] refer to image 3 The positioning assembly 6 includes an overall L-shaped positioning plate 61 fixed on the inner wall of the agitator 12, the positioning plate 61 is located below the water inlet pipe 121 and the opening formed with the inner wall of the agitator 12 faces upward...

Embodiment 3

[0052] refer to Figure 5 with Image 6 , the difference between the present embodiment and embodiment one and embodiment two is that: one end of each shear plate 4 towards the inner wall of the agitator 12 is provided with a shear groove 42, so that each shear plate 4 is connected to the agitator 12 A shear seam is formed between the inner walls for flocs to pass through.

[0053] When the paddle 2 drives the flocs to rotate inside the agitator 12, the flocs will pass through the shear joints, and when the flocs enter the shear joints, the shear plate 4 will block the flocs. Under the condition that the rotation force of the flocs in the agitator 12 is constant, the flow velocity will increase rapidly when the flocs pass through the shear seam, and the flow velocity of the part of the flocs flowing out from the shear seam will become faster and the part located in the shear seam Part of the flow rate remains unchanged, thereby generating a tearing force on the flocs, and th...

Abstract

The invention relates to a high-efficiency deflocculation machine, and relates to the technical field of sewage treatment. The machine comprises a vertically placed cylindrical deflocculation machinebody; a water inlet pit communicates with the outer wall of the deflocculation machine body; a water outlet pipe communicates with the outer wall of the deflocculation machine body; the water inlet pipes and the water outlet pipes are symmetrically arranged along the axis of the deflocculation machine body; a stirring paddle is rotatably connected with the inside of the deflocculation machine body; a driving assembly is arranged at the upper end of the deflocculation machine body and drives the stirring paddle to rotate; the driving device comprises a motor and a reducer which is fixedly connected with an output shaft of the motor; an output shaft of the reducer is fixedly connected with the stirring paddle; a shearing plate is arranged on the inner wall of the deflocculation machine body;the length direction of the shearing plate is consistent with the axial direction of the deflocculation machine; and the shearing plate is positioned between the water inlet pipe and the water outletpipe. The deflocculation machine has the effects that, the service life of the deflocculation machine is improved while the deflocculation quality thereof is improved, and sludge and heavy media canbe more thoroughly separated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency deflocculation machine. Background technique [0002] Deflocculation machine, short for high-speed shear deflocculation machine, commonly known as high-speed deflocculation machine, high shear machine, is one of the key equipment in the heavy medium coagulation sedimentation water treatment process. The dense medium coagulation sedimentation technology achieves the purpose of rapid sedimentation by adding a denser floc kernel - dense medium powder - into the water body. The method is fast and efficient, and has a stable and excellent removal effect on SS and TP in water. The deflocculation machine is used to deflocculate the flocs of the heavy medium powder, so that the heavy medium powder can be recovered and recycled. [0003] Existing deflocculation machines usually use a motor to drive the stirring paddle to stir the mixture of sludge and heavy me...
