Automatic thickening pond

Abstract

The invention provides an automatic thickening pond. The automatic thickening pond comprises a pond body; the bottom end of the pond body is provided with a mud bucket; a mud scraping device is arranged in the mud bucket and comprises trusses, a mud scraping plate arranged at the bottom ends of the trusses and a transmission shaft hinged with corresponding ends of the two trusses; the transmission shaft is connected with a drive unit located at the top end of the pond body; a mud level sensing device is mounted in the pond body and comprises a vertical and downward hanging rope and a suspension type sensor connected with one end of the hanging rope; the drive unit is electrically connected with a mechanical resistance signal sensor; the upper end of the pond body is further provided with a control system; the control system comprises a PLC processing unit, a signal storage unit and a wireless signal receiving unit; the bottom end of the mud bucket is provided with a mud discharging system; the mud discharging system comprises a mud discharging pipeline and a solenoid valve mounted on the mud discharging pipeline; the suspension type sensor and the mechanical resistance signal sensor are both in signal connection with the wireless signal receiving unit; the wireless signal receiving unit is electrically connected with the PLC processing unit; the PLC processing unit is electrically connected with the signal storage unit; and the solenoid valve is electrically connected with the PLC processing unit.

Description

technical field [0001] The invention is designed in the field of sewage treatment, and in particular relates to sludge treatment. Background technique [0002] The thickening tanks in the prior art all include a sludge scraper device, and the automatically deposited sludge is discharged by a sludge scraper, but it needs to be manually operated at intervals, the degree of automation is not high, and the work efficiency is low. When there is too much sludge deposited, it will The driving device is overloaded and burnt out for a long time, which greatly shortens the service life and increases the operating cost, which needs to be improved. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a fully automatic thickening tank with high degree of automation, simple structure, automatic detection and automatic mud discharge. [0004] In order to achieve the purpose of the present invention, the following technical solutions ar...
