Abstract
Description
Technical Field
[0001] The utility model relates to an automatic pressure-relieving waste water pump, belonging to the technical field of the structural design of the water outlet of the waste water pump. Background Art
[0002] At present, the waste water generated by the desulfurization system during deslagging is usually pumped to the sewage treatment station by a waste water pump for treatment. During the actual sewage treatment process, sometimes due to excessive waste water volume, the sewage treatment station fails to handle it in time. At this time, the staff usually adjusts the sewage discharge valve to a smaller size, which will cause the pressure in the desulfurization waste water discharge pipeline to increase. When the pressure in the waste water discharge pipeline exceeds 0.4 MPa, water leakage often occurs at the connection between the waste water pump and the sewage discharge pipe. Therefore, repairs are often required, which not only wastes manpower but also affects the normal discharge of waste water. Content of the Utility Model
[0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an automatic pressure-relieving waste water pump that can automatically relieve the pressure of the sewage discharge pipeline.
[0004] The automatic pressure-relieving waste water pump described in the utility model includes a waste water pump body. There is a water outlet on the waste water pump body. A pressure-relieving hole is opened on the side wall of the water outlet. A pressure-relieving body is provided on the outer side wall of the water outlet. The pressure-relieving body penetrates up and down. The lower end inside the pressure-relieving body is connected with a pressure-relieving bushing corresponding to the pressure-relieving hole. A plug is connected in a matching manner at the upper port of the pressure-relieving bushing. A lower spring seat is provided at the top of the plug. The upper end of the pressure-relieving body is hermetically connected with a mounting seat. An upper spring seat is connected inside the mounting seat. A spring is installed between the upper spring seat and the lower spring seat. A pressure-relieving port is provided on the side wall of the pressure-relieving body.
[0005] Preferably, a sliding hole is provided inside the mounting seat. A slider is slidably connected in the sliding hole. The slider is connected with a slider adjusting assembly. The upper spring seat is arranged at the bottom of the slider. The position of the slider in the sliding hole can be adjusted through the slider adjusting assembly, so as to adjust the elastic force value of the spring, thereby achieving the purpose of adjusting the pressure-relieving pressure.
[0006] Preferably, a clamping groove is opened on the outer side wall of the slider. A sealing ring is connected in the clamping groove. The sealing ring can achieve the seal between the slider and the mounting seat, preventing waste water from leaking out of the mounting seat.
[0007] Preferably, chamfers are provided at both the upper and lower ends of the slider, making the movement of the slider smoother when adjusting the position of the slider.
[0008] Preferably, the slider adjustment assembly includes a nut welded on the mounting seat, the inner thread of the nut is connected to an adjusting screw that passes through the mounting seat, one end of the adjusting screw located inside the mounting seat is against the slider, and the end of the adjusting screw located outside the mounting seat is provided with an adjusting part, which is driven by the adjusting part to rotate the adjusting screw. Under the action of the nut, the adjusting screw moves up and down when rotating, thereby achieving the purpose of adjusting the position of the slider. The structure is simple and the operation is convenient.
[0009] Preferably, the adjustment portion is a straight hexagonal hole, and the adjustment portion can be adjusted by a hexagonal wrench, which is very convenient.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] The automatic pressure relief wastewater pump described in the utility model can, when the pressure in the sewage pipe is too high, allow the wastewater to pass through the pressure relief hole and the pressure relief bushing to resist the elastic force of the spring and push the plug away from the upper port of the pressure relief bushing, so that the wastewater is discharged through the pressure relief hole to achieve the purpose of pressure relief, thereby preventing water leakage at the connection between the wastewater pump and the sewage pipe due to the high water pressure, which not only saves manpower but also ensures the normal discharge of wastewater.
