Description

Technical Field

[0001] The utility model relates to the technical field of flocculant addition, in particular to an automatic flocculant addition device. Background Art

[0002] Flocculation and sedimentation are often used in sewage treatment. The flocculation and sedimentation method is to select inorganic flocculants (such as aluminum sulfate) and organic anionic flocculants polyacrylamide (PAM) to prepare an aqueous solution and add it to the wastewater, which will produce a compressed double layer, making the suspended particles in the wastewater lose stability, and the colloids coagulate with each other to enlarge the particles, forming floccules and alum flowers. When the floccules grow to a certain volume, they will separate from the water phase and precipitate under the action of gravity, thereby removing a large amount of suspended matter in the wastewater, thereby achieving the effect of water treatment. In order to improve the separation effect, coagulants can be added in a timely and appropriate amount. The treated sewage can basically meet the discharge standards in terms of color, chromium content, suspended matter content, etc. When in use, flocculants need to be added to the stored sewage.

When the flocculant in the connecting tube 7 reaches a position parallel to the infrared spotlight 27, a signal can be transmitted to the controller 28 under the action of the infrared spotlight 27. At this time, the valve one 4 can be closed by the controller 28 to stop the flocculant from entering.

[0040] Working principle: Valve 1 4 can be opened by controller 28, and the flocculant in the collecting box 2 can enter the connecting pipe 7. When the infrared spotlight 27 detects that the flocculant has reached a specified height, it will send a signal to the controller 28, and then valve 1 4 can be closed to stop the flocculant from entering. The piston 10 can squeeze the flocculant in the connecting pipe 7 by driving the cylinder 9. At this time, valve 2 8 can be opened by controller 28, and the flocculant can be discharged. There is no need for manual operation by employees, which reduces the labor intensity of employees and increases the speed of adding flocculants.

[0041] Among them, by pressing the pressure rod 16, the connecting disk 15 can drive the movable plate 14 to compress the compression spring 13. At this time, the block 17 is inserted into the mounting plate 11 and passes over the mounting plate 11 and then the mounting plate 2 12 is rotated, so that the pressure rod 16 can slide in the slide groove 18. When the pressure rod 16 cannot slide, the pressure rod 16 can be released and the block 17 can be pulled into the groove 19 under the action of the compression spring 13. At this time, the pipeline 6 and the connecting pipe 7 can be quickly connected and fixed.
