A self-priming device for waste liquid transportation and its realization method

Abstract

The invention discloses a self-priming device for transporting waste liquid and its realization method, which comprises: a waste liquid collection tank for collecting waste liquid; a submerged pump whose inlet extends into the waste liquid collection tank, and The outlet of the pump is connected with the first infusion pipe; the inlet of the self-priming pump is connected with one end of the liquid inlet pipe, and the other end of the liquid inlet pipe extends vertically downward into the waste liquid collection tank, and the other end of the liquid inlet pipe One end is provided with a liquid suction head; the outlet of the self-priming pump is respectively connected with the second infusion pipe and the outlet of the submerged pump, and the self-priming pump is provided with an exhaust valve; the height adjustment mechanism is arranged in the waste liquid collection tank In the middle, the height adjustment mechanism is connected with the liquid inlet pipe, and is used to adjust the height of the liquid suction head in the waste liquid collection tank; the scrubbing unit is arranged on the height adjustment mechanism, and the scrubbing unit is used to scrub the liquid suction head. The invention reduces the overall maintenance workload and manpower input, and is applicable to the transportation of various waste liquids and different liquid level requirements.

Description

Technical field [0001] The present invention relates to the technical findings of coking waste collecting devices, and more particularly to a self-suction device for waste liquid delivery. Background technique [0002] The waste liquid collection tank between the coking plant is mainly used to include each reservoir of cold drums, mechanized ammonia water clamings, due to the discharge of the viscosity substance, and the waste collection tank The liquid is mainly transmitted by the liquid under liquid pump. Since the material is transported, the liquid pump is extremely difficult to damage, the maintenance is not in time, resulting in a waste liquid to collect the groove groove, causing serious environmentally friendly pollution, while the waste collecting tank lower pump Length of the axis, the pump shaft needs to be hang to the ground when the maintenance is maintained, causing a large repair difficulty, low work efficiency, and high labor intensity.

AI Technical Summary

Problems solved by technology

[0002] The waste liquid collection tank in the chemical production workshop of the coking plant is mainly used to hold the vents of the storage tanks in the cold drum section and the mechanized ammonia clarification tank. Since the vents contain viscous substances such as tar, the waste liquid in the waste liquid collection tank The liquid is mainly transported through the submerged pump. Due to the characteristics of the material to be transported, the submerged pump is easily damaged. If the maintenance is not timely, the waste liquid collection tank will overflow, causing serious environmental pollution accidents. At the same time, the waste liquid collection tank submerged pump The shaft is long, and the pump shaft needs to be hoisted to the ground before it can be operated during maintenance, resulting in difficult maintenance, low work efficiency, and high labor intensity
