A continuous production line waste water recycling control device

Abstract

The invention discloses a production wastewater recovery control device for a continuous operation line, which is provided with several motors (1), several self-priming pumps (9) and water storage buckets (7), and each motor (1) corresponds to each self-priming Suction pump (9), each motor (1) is connected to each self-priming pump (9) by transmission, and the water inlets of several self-priming pumps (9) are connected to the water outlet of the water storage bucket (7) after being collected , the water outlet of each self-priming pump (9) is connected with the water inlet (12) of the sewage station (11) through the water outlet pipe (10), and the waste water outlet (13) of the sewage station (11) is connected with the water containing Acid, alkali, phosphorus and other waste water are collected from low-level pools (8) connected to each other. A ball valve (3) is installed at the water inlet on the top of the water storage bucket (7), and a check valve (2) is connected to the side of the water storage bucket (7). The check valve (2) stretches into the low-level pool (8) for collecting waste water containing acid, alkali and phosphorus.

Description

technical field [0001] The invention relates to a production waste water recycling control device for a continuous operation line. Background technique [0002] Production wastewater containing acid, alkali, phosphorus, etc. in electroplating, heat treatment and other production lines is collected from each section tank to each low-level collection pool, and then the self-priming pump is controlled according to its liquid level to transport various types of wastewater to Sewage treatment station treatment. The shortcomings of the existing recovery control are: 1. Due to the large height difference between the liquid surface of each low-level pool and the ground (up to 2.5 meters or more), the self-priming pump inlet pipeline has a long air section, and the pump outlet needs more than ten The waste water can be pumped out within 10 minutes; 2. During this time, because the pump has no output, it is impossible to know whether the pump is working normally; 3. The pump is easil...

AI Technical Summary

Problems solved by technology

The shortcomings of the existing recovery control are: 1. Due to the large height difference between the liquid surface of each low-level pool and the ground (up to 2.5 meters or more), the self-priming pump inlet pipeline has a long air section, and the pump outlet needs more than ten It takes only 10 minutes to pump out the wastewater; 2. During this time, because the pump has no output, it is impossible to know whether the pump is working normally; 3. The pump is easily damaged due to heat due to long-term idling due to dehydration.
