Chemical fiber production wastewater pool capable of realizing automatic closing and opening for blowdown

Abstract

The invention provides a chemical fiber production wastewater pool capable of realizing automatic closing and opening for blowdown. A water inlet is formed in one side of the wastewater pool, and a blowdown opening is formed in the other side of the wastewater pool; a buoy communicating with wastewater in the pool is arranged in the wastewater pool, a floating body is arranged in the buoy, a floating touch block which is located on the outer side of the buoy is arranged on the rod body of a floating rod which is integrally connected with the upper end of the floating body, an electric source switching-on touch block is arranged on the upper side of the buoy, and an electric source switching-off touch block is arranged at the position, below the floating touch block, of the outer side of the buoy; and the electric source switching-on touch block is provided with a switching-on line which is connected with an electric source starter near the blowdown opening, the electric source switching-off touch block is provided with a switching-off line which communicates with the electric source starter, the electric source starter is connected with a blowdown motor through a connecting line, and the blowdown motor is connected with a blowdown pump mounted on the blowdown opening through a coupling. When the chemical fiber production wastewater pool is used, wastewater stored in the wastewater pool can drive the floating body and the floating rod to rise and fall along with a water level, when the water level reaches an upper limit, the motor is switched on, then wastewater is drained outwards, when the water level falls to the lower limit, the motor is switched off, and blowdown is stopped, so that the purpose of automatic adjustment and control for blowdown can be achieved.

Description

technical field [0001] The invention relates to a chemical fiber production facility, in particular to a chemical fiber production wastewater pool with automatic on-off sewage discharge. Background technique [0002] In the production of viscose filaments in the chemical fiber industry, a lot of acid-base wastewater will be produced. The conventional method is to build a wastewater pool to store and collect it first, and then pump it into the purification pipe network after reaching a certain storage capacity. Usually, electrodes will be installed. Type or float type liquid level device for automatic regulation and sewage discharge, but the stored wastewater contains acid-base mixture, after a period of use, the liquid level device will corrode and cause self-control failure. For this reason, existing chemical fiber enterprises will There is often a phenomenon of waste water overflow causing pollution. Contents of the invention [0003] In order to effectively solve the a...
