Description

Technical Field

[0001] The utility model relates to the technical field of phosphorus removal and restoration equipment, in particular to equipment for phosphorus removal and ecological restoration. Background Art

[0002] For traditional water quality phosphorus removal and restoration, water needs to be introduced into a specified device, and a high-power motor is used to stir water and a phosphorus remover so that the water and the phosphorus remover are fully contacted for phosphorus removal treatment. However, this will cause the sand and gravel in the water to be continuously stirred and unable to precipitate and separate, and the functional energy consumption required by the device is very large. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: in order to overcome the above problems, equipment for phosphorus removal and ecological restoration is provided, which solves the above problems.

[0004] The utility model solves its technical problem by adopting the following technical solutions:

[0005] The equipment for phosphorus removal and ecological restoration includes a water tank provided with a water inlet joint. A spiral guide plate is fixedly welded in the water tank. After sewage is added from the water inlet joint, it flows in the water tank and finally discharges from the middle drain outlet of the water tank under the guiding action of the spiral guide plate. A water pipe can be externally connected to the drain outlet between the water tanks. A bucket-type filter is arranged in the flow channel in the water tank to filter sand and gravel and make it precipitate for convenient regular cleaning. And a phosphorus remover tank is arranged on the flow channel in the water tank to quantitatively discharge the phosphorus remover into the flowing water for mixing and phosphorus removal.

[0006] Preferably, a clamping groove is arranged on the spiral guide plate. The bucket-type filter includes an insertion plate for inserting into the clamping groove and a filter hopper fixed at the front end of the insertion plate. And the filter hopper and the insertion plate are provided with sieve holes. A sunken filter settling pit is arranged at the corresponding position of the water tank for embedding the bucket-type filter. After the bucket-type filter is installed in place, the lower end of the filter hopper touches the bottom of the filter settling pit, and the upper end of the insertion plate is higher than the upper end of the spiral guide plate, which is convenient for taking when cleaning. After the water flows through the bucket-type filter, the sand and gravel are intercepted and deposited under the action of gravity, which will not affect the flow. It is very scientific and reasonable. When a certain degree is accumulated, the bucket-type filter can be taken out for cleaning, which is efficient, simple and convenient.

[0007] Preferably, a dephosphorizing agent tank with a feeding port is fixedly arranged on the upper end surface of the spiral guide plate. A driving motor is further arranged on the top of the dephosphorizing agent tank. A screw rod is coaxially connected to the rotating shaft of the driving motor. A discharging cylinder is fixedly arranged on the upper end surface of the dephosphorizing agent tank. The screw rod extends into the discharging cylinder, and a rubber sheet with a cross-knife incision is fixedly arranged on the lower end surface of the discharging cylinder. After the driving motor drives the screw rod to rotate, the screw rod extrudes the dephosphorizing agent, causing the rubber sheet to deform and open the cross-knife incision, and discharging downward, mixing into the water flow for dephosphorization. Since the water flow rapidly flows in the spiral water channel, the dephosphorizing agent is rapidly mixed, which is very efficient and convenient.

[0008] Preferably, in order to improve the water flow smoothness, the lower end surface of the water tank has a slope, which is a ramp sloping downward from the outside to the inside along the direction of the water channel. In this way, after the sewage is added from the water inlet joint, it rapidly circulates under the action of the slope.

[0009] Preferably, a floating matter filter cylinder is fixedly arranged in the middle of the water tank. The upper half of the floating matter filter cylinder is provided with through holes, and the lower half is a closed cylindrical structure, so that the floating matter can be filtered, which is convenient for subsequent centralized cleaning.

[0010] The advantages and positive effects of the present utility model are:

[0011] 1. The structure is simple and ingeniously designed. Through the spiral water channel and slope design, the water flow rapidly flows, and by mixing and adding the dephosphorizing agent through the dephosphorizing agent tank, efficient and orderly mixed dephosphorization can be achieved. Compared with the existing stirring equipment, although the water also flows, this device omits the large motor for driving the water flow, reducing the cost and energy consumption.

[0012] 2. The semi-submersible bucket-type filter effectively filters and precipitates the sediment, and does not affect the water flow in the water channel. The design is ingenious and has strong practicability.

[0013] 3. Through the structures such as the dephosphorizing agent tank, discharging cylinder, driving motor and screw rod, the dephosphorizing agent is quantitatively and continuously added into the flowing water flow in an orderly manner, forming an efficient continuous flow treatment and improving the treatment efficiency.

[0014] 4. The floating matter filter cylinder filters the floating matter impurities, which is efficient and simple. Description of the Drawings
