Condensate drainer

Abstract

The invention relates to a condensate drainer. The drainer comprises a shell body, an electronic liquid level sensor, an electric valve, a control unit and a filter net. The shell body is provided with a liquid collecting cavity, a water inlet and a water outlet; the water inlet and the water outlet communicate with the liquid collecting cavity respectively; the electronic liquid level sensor is arranged in the liquid collecting cavity and is for detecting the liquid level of condensate in the liquid collecting cavity; the control unit is for controlling the electric valve to open or close based on a liquid level signal from the electronic liquid level sensor; the filter net is arranged in the liquid collecting cavity and divides the liquid collecting cavity into an upstream cavity and a downstream cavity; and the filter net is for filtering solid particles in the condensate and blocking the solid particles in the upstream cavity. The condensate drainer is not prone to being blocked bythe solid particles and is safe and reliable. The maintenance is simple and convenient and the maintenance cycle is long. Waste of energy caused by faults of the condensate drainer or by compressed air leakage can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of drainage equipment, and relates to a condensate drainer, in particular to a condensate drainer used in a compressed air system. Background technique [0002] Compressed air systems usually require a condensate drain to remove the condensate formed in the pipes and containers of the compressed air system. The condensate mainly contains water, oil and solid particles. The water mainly comes from the moisture in the ambient air sucked by the air compressor. The oil mainly comes from the lubricating oil of the air compressor. The solid particles include non-metallic particles and metal particles. The condensate The water mixed with oil, non-metallic particles and metal particles flow with the flow of compressed air. [0003] The condensate discharger in the prior art generally realizes the condensate discharge operation through the control of the valve. According to the different control methods of the valve...

AI Technical Summary

Problems solved by technology

[0005] Float control ejectors often have solid particles embedded that prevent the float from moving up and down properly, causing the condensate ejector to fail

The time-controlled ejector opens the valve according to the set time interval. However, when the condensate is less, the valve is still open after the condensate is discharged, and a large amount of compressed air will be released, causing a lot of waste and increasing the user's energy consumption. The cost

The condensate discharger with electronic liquid level control usually controls the opening and closing of the valve according to the liquid level in the liquid collection tank. Although it can reduce the waste of compressed air to a certain extent, when solid particles accumulate at the valve position of the discharger , will cause the valve to not be completely closed, and when the condensate is discharged, the compressed air will continue to leak, and there is still energy waste
