Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a separation device for sewage treatment and a use method thereof. Background Art

[0002] Wastewater treatment refers to the removal or reduction of various harmful substances in sewage through a series of physical, chemical and biological methods, and ultimately converting it into water quality that can be safely discharged or recycled. Wastewater treatment usually includes multiple stages such as pretreatment, primary treatment, intermediate treatment, advanced treatment and disinfection. When performing primary treatment of sewage, filtration and separation equipment is required to filter and treat the sewage.

[0003] Existing separation equipment for sewage treatment usually has multiple filters inside the separation box to filter the sewage, and the filters are usually fixed inside the separation box. When cleaning the filters, they usually need to be removed and rinsed, which makes the cleaning operation of the filters more cumbersome and inconvenient; and the sewage generated after rinsing the filters is usually discharged directly, while new rinse water is used when flushing the separation box, which increases the amount of rinse water used and increases the cost of cleaning the separation equipment. For this reason, we propose a separation equipment for sewage treatment. Summary of the invention

[0004] The object of the present invention is to provide a separation device for sewage treatment to solve the problems in the above background technology that the cleaning operation of the filter is relatively cumbersome and inconvenient and the direct discharge of sewage generated after flushing the filter increases the amount of cleaning water.

[0005] To achieve the above object, the present invention provides the following technical solution: a separation device for sewage treatment, comprising:

[0006] A separation box, wherein a top part is arranged on the top of the separation box, a filter screen is arranged inside the separation box, a connecting column is arranged on the top of the filter screen, a cross column is arranged on the top of the connecting column, an electric push rod fixed to the outside of the top part is arranged at the bottom of the cross column, the electric push rod is electrically connected to a forward and reverse switch, a flushing part is arranged inside the top part, and a plurality of nozzles are arranged on the side wall of the flushing part;

[0007] A displacement bucket is matched with the interior of the top component, a retaining net is arranged inside the displacement bucket, a filter is arranged at the bottom of the displacement bucket, a coarse filter and a dense filter are arranged inside the filter, a connecting pipe is arranged on the side wall of the filter, and a pressure pump is arranged at the output end of the connecting pipe.

[0008] Preferably, the outer wall of the electric push rod is provided with a plurality of fixing plates.

[0009] Preferably, the forward-reverse switch is fixed to the side wall of the separation box.

[0010] Preferably, the connecting column passes through the top of the top component.

[0011] Preferably, the bottom of the displacement bucket is equipped with a support plate.

[0012] Preferably, the pressure pump is fixed to the bottom of the filter element.

[0013] Preferably, the flushing member is fitted into a side wall of the connecting column.

[0014] Preferably, a water inlet is fixedly connected to the top of the separation box.

[0015] A method for using a separation device for sewage treatment comprises the separation device for sewage treatment.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention drives the connecting column to move upward through the horizontal column after the electric push rod is extended, so that the filter screen rises from the inside of the separation box to the inside of the top component, and then the nozzle of the flushing component sprays water to flush the filter screen, thereby realizing the convenient removal of the filter screen from the inside of the separation box for cleaning, solving the inconvenience of using tools to remove the filter screen inside the separation box for flushing, and making the cleaning operation of the separation equipment more convenient.

[0018] 2. When flushing the filter screen, the present invention pushes the displacement bucket toward the inside of the top component. At this time, the displacement bucket cooperates with the bottom of the filter screen. The sewage generated after flushing can flow into the displacement bucket, and then the larger impurities in the sewage are blocked by the blocking net. The sewage then flows into the interior of the filter element and is filtered by the coarse filter screen and the dense filter screen. Then the pressure pump extracts the sewage filtered at the bottom of the filter element and can be used to flush the separation box, so that the sewage flushed from the filter screen can be filtered and reused, saving the amount of cleaning water used when cleaning the separation equipment for sewage treatment and reducing the water cost.
