Description
Technical Field
The utility model relates to the technical field of foundation pit drainage, in particular to a sediment discharging and backflow preventing device of a sewage pump.
Background
Foundation ditch dewatering is when the excavation foundation ditch, and the groundwater level is higher than the excavation bottom surface, and in groundwater can constantly permeate the hole, in order to guarantee that the foundation ditch can be under the dry condition construction, prevent that problems such as side slope unstability, foundation sand flow appear, need carry out dewatering work. The open drainage dewatering is to dig a drainage ditch outside the foundation, and then to introduce water into the water collecting well for unified water pumping. However, the sediment content in the water in the foundation pit is large, sediment settlement can be generated in the water pumping process, the drain pipe is blocked, and the phenomenon that the water pump is blocked due to sediment backflow can occur when emergency such as power failure is encountered.
Disclosure of Invention
In order to solve the technical problems, the utility model provides a sediment discharging and backflow preventing device for a sewage pump, which can effectively prevent sediment from flowing reversely and avoid blocking a pipeline or a water pump.
In order to achieve the technical purpose, the utility model adopts the following scheme:
the silt and countercurrent preventing device for sewage pump comprises a device body, wherein the device body is of a cylindrical structure, a water outlet is formed in the upper portion of the device body, a water inlet pipe is arranged on the side wall of the device body and is communicated, the water outlet end of the water inlet pipe is obliquely inserted into the device body, a baffle plate is hinged to the upper portion of the water outlet end of the water inlet pipe, and a sedimentation chamber is further arranged on the lower portion of the device body.
Further, the limiting piece is fixedly arranged on the side wall of the device body above the water outlet end of the water inlet pipe, the limiting piece is abutted against the limiting piece when the baffle plate is completely opened, the limiting piece can prevent the baffle plate from being excessively large in opening angle, and the baffle plate cannot fall back to cover the water inlet pipe, so that the function of preventing backflow is lost.
Further, the device body below the water outlet is of a conical cylinder structure, and the inclined surface of the conical cylinder is opposite to the water outlet end of the water inlet pipe.
Further, the lower part of the sedimentation chamber is provided with a sand unloading valve, and the deposited sediment can be cleaned regularly.
Compared with the prior art, the utility model has the beneficial effects that:
the upper part of the water outlet end of the water inlet pipe of the sewage pump sediment discharging and backflow preventing device is hinged with a baffle plate, when the water pump works, water flow impacts and opens the baffle plate, impacts an inclined plane, and flows to a water band connected subsequently through a water outlet; when the water pump stops working, the baffle plate falls back to cover the water inlet pipe, so that the water can be prevented from flowing back; the device is also provided with a settling chamber, the sediment-containing sewage is settled in the settling chamber, and settled sediment can be cleaned regularly through a sediment discharge valve. The device has the advantages of simple structure, convenient operation, effective prevention of sediment backflow, avoidance of blockage of pipelines or water pumps, realization of continuous precipitation and guarantee of construction progress.

Detailed Description
The present utility model will be described in detail with reference to the following embodiments for a full understanding of the objects, features and effects of the present utility model, but the present utility model is not limited thereto.
Referring to fig. 1 and 2, a sewage pump discharges silt and prevents device against current, including tubular structure's device body 7, device body 7 upper portion is provided with delivery port 4, device body 7 lateral wall is provided with the oral siphon 1 of intercommunication, oral siphon 1's play water end slant upward inserts the inside of device body 7, oral siphon 1's play water end upper portion articulates there is baffle 3, be fixed with spacing piece 2 that the level set up on the device body 7 lateral wall above oral siphon 1 play water end, with spacing piece 2 butt when baffle 3 is opened completely, spacing piece 2 prevents that baffle 3 opens the angle too big, can not fall back on oral siphon 1, lose the function against current. The device body 7 below the water outlet 4 is of a conical cylinder structure, and the inclined surface 5 of the conical cylinder is opposite to the water outlet end of the water inlet pipe 1. The lower part of the device body 7 is also provided with a sedimentation chamber 6, and the lower part of the sedimentation chamber 6 is provided with a sand unloading valve.
The utility model relates to a working principle of a sediment discharging and backflow preventing device of a sewage pump, which comprises the following steps: in the precipitation operation process, the water outlet end of the sewage pump is connected with the water inlet end of the water inlet pipe 1, water enters from the water inlet end of the water inlet pipe 1, the baffle plate 3 at the water outlet end of the water inlet pipe 1 is flushed, the water flow impacts the inclined plane 5, sediment is deposited downwards, and the water flows to a water band connected subsequently through the water outlet 4. When the sewage pump stops working, the water flowing back impacts the baffle plate 3, so that the baffle plate 3 covers the water outlet end of the water inlet pipe 1, the water is prevented from flowing back into the water pump, the water flowing back is deposited in the sedimentation chamber 6, and the sand discharging valve is opened periodically to clean the sediment.
