Environment-friendly liquid level alarm system for papermaking clear-water basin

Abstract

The invention relates to an environment-friendly liquid level alarm system for a papermaking clear-water basin. The system comprises a floating ball liquid level controller, a control box, a pump, analarm and a water quality monitoring sensor. A floating ball of the floating ball liquid level controller is arranged at the liquid surface of the basin. The water quality monitoring sensor is arranged at the bottom of the basin. The floating ball liquid level controller and the water quality monitoring sensor are connected to the control box whose output end is connected to the pump and the alarm. Compared with the prior art, according to the system, the liquid level of the clear-water basin is effectively controlled, a safety production accident due to a human error is avoided, and the lossand waste caused by the affection of the normal production of a paper machine due to a low water level and the overflow of clean water with a high water level are avoided. At the same time, due to thesetting of the water quality monitoring sensor, the pH, temperature, turbidity and dissolved oxygen of water quality can be tested, when the water quality is not up to standard, the water quality monitoring sensor sends a signal to the control box, the control box controls the alarm to emit an alarm, and the staff is timely reminded to take effective measures.

Description

technical field [0001] The invention relates to a liquid level alarm system, in particular to an environment-friendly liquid level alarm system for papermaking clear water tanks. Background technique [0002] The clean water pool in the water treatment department is responsible for providing sufficient and high-quality clean water for the paper machine production. However, as a key component of the system, manual inspection is required to operate water replenishment and water supply. The human factor has become an important part of restricting efficient production, resulting in huge downtime and equipment losses. . And in many cases, the water quality of the clear water pool cannot be guaranteed sometimes, which affects the production quality of subsequent products. In the prior art, there is a lack of real-time monitoring of the water quality of the clear water pool, and the product quality cannot be guaranteed.

[0002] The clean water pool in the water treatment department is responsible for providing sufficient and high-quality clean water for the paper machine production. However, as a key component of the system, manual inspection is required to operate water replenishment and water supply. The human factor has become an important part of restricting efficient production, resulting in huge downtime and equipment losses.

And in many cases, the water quality of the clear water pool is sometimes not guaranteed, which affects the production quality of subsequent products. In the prior art, there is a lack of real-time monitoring of the water quality of the clear water pool, and the product quality cannot be guaranteed.

[0003] Chinese patent CN 103885466 A discloses a liquid level control system. The liquid level control system includes a first control valve connected to the water inlet pipe of the liquid level pool to be measured, a second control valve connected to the water outlet pipe of the liquid level pool to be measured. Control valve and liquid level change sensing mechanism; the liquid level change sensing mechanism includes a substrate, a floating ball assembly, a rocker mechanism and a mercury switch; the floating ball assembly is installed on the substrate, and the floating ball assembly is connected to the mercury switch through the rocker mechanism. The middle electrode and one side electrode can be connected by tilting the switch. The structure of the liquid level control system is relatively complicated, the cost is high, and the investment cost of the enterprise is increased. It is not suitable for the liquid level control of the papermaking clear water tank.
