However, the construction cost of this type of water treatment is generally high. It is suitable for large water volume treatment, but the construction and operation costs are high for small water volume treatment. There is a lack of equipment in the current technology field for continuous pretreatment of wastewater. Utility Model Content

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.
[0019] Combined with appendix Figure 1-3A water treatment stirring device includes a water treatment tank body 1, which includes an internal stirring sedimentation layer 2. A wastewater injection pipe 3 connected to one side of the water treatment tank body 1 and communicating with the internal stirring sedimentation layer 2 is provided. A partition plate 4 is connected to the top of the internal stirring sedimentation layer 2. The partition plate 4 has multiple water passage holes 5. A filter cylinder 6 is connected to the bottom of the water passage holes 5. The filter cylinder 6 has a structure in which a metal mesh cylinder is provided inside and a cloth cover is fixedly wrapped on the outside, so as to filter waste solids in the water. However, this type of filter is only suitable for industrial manufacturing and is not suitable for more refined food and chemical products. A flocculant addition pipe 12 extending to the top of the internal stirring sedimentation layer 2 is connected to the top of the water treatment tank body 1. A flow control valve 13 is connected to the flocculant addition pipe 12, which, in conjunction with the flow control valve 13, facilitates the injection of flocculant.
[0020] The water treatment tank body 1 is equipped with a stirring motor 8 at the top. The bottom power end of the stirring motor 8 is connected to a stirring shaft 9 extending into the internal stirring sedimentation layer 2. Multiple stirring rods 10 are connected to the outside of the stirring shaft 9. Multiple scrapers 11 that are in close contact with the inner wall of the internal stirring sedimentation layer 2 are connected to the top outside of the stirring shaft 9. With the addition of flocculant, the stirring motor 8, stirring shaft 9 and stirring rods 10 can be used to stir and mix, accelerating the sedimentation speed of waste solids. However, the stirring speed should not be too fast, as it may agitate the sediment at the bottom. At the same time, the scrapers 11 can prevent excessive adhesion of waste solids to the inner wall of the internal stirring sedimentation layer 2.
[0021] The bottom of the water treatment tank body 1 is connected to a sludge collection and discharge pipe 14. A clean water discharge pipe 7 communicating with the top of the partition plate 4 is connected to one side of the water treatment tank body 1. A sludge suction pipe 16 is connected to the bottom of the sludge collection and discharge pipe 14. A sludge suction pump 15 is connected to the end of the sludge suction pipe 16. An electric control valve 17 is connected to the sludge suction pipe 16. The sludge suction pump 15 and the electric control valve 17 are connected in series and start and stop synchronously. By periodically starting the sludge suction pump 15, the sludge sediment in the sludge collection and discharge pipe 14 can be extracted.
[0022] The water treatment tank body 1 is equipped with a water pump 18 at the top. The water pump 18 is connected to a water pumping pipe 19 and a water outlet pipe 20 that communicate with the upper part of the partition plate 4. The water outlet pipe 20 extends to the upper part of the partition plate 4 and is connected to a water distribution ring pipe 21. The water distribution ring pipe 21 extends into the filter cylinder 6 and is connected to a water spray pipe 22. The water spray pipe 22 has multiple water outlets 23 at its inner end in the filter cylinder 6. The water pump 18 draws the filtered water from the filter cylinder 6 and circulates it into the water distribution ring pipe 21 and the water spray pipe 22. With the multiple water outlets 23, the outside of the filter cylinder 6 can be cleaned regularly, which can prevent excessive solid waste from sticking to the filter cylinder.
[0023] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
