Problems solved by technology

However, this kind of device needs to expose and soak the contact elements in the liquid containing acid and alkali, which is very easy to be corroded, and it will also be affected by impurities in the waste water, which will cause the control system to fail, and even cause the production line to be paralyzed; the water pump repeatedly Starting and stopping may also easily cause the water pump to be evacuated and burn out, which will affect the health of the equipment

Embodiment 1

[0024] Such as Figure 1-3 As shown, a waste water pool anti-evacuation device includes a waste water pool 1, an anti-evacuation protection part 2 and a control cabinet 3; the waste water pool 1 is provided with a water inlet pipe 10 and an outlet pipe 11; the water outlet pipe 11 is connected to a water pump 9. The anti-evacuation protection part 2 includes a liquid level transmitter 4, a grid bracket outer cylinder 5, a protection mesh cylinder 6 and a cleaning chamber 7; the grid bracket outer cylinder 5 is arranged in the waste water pool 1; the The protective mesh cylinder 6 is set in the outer cylinder 5 of the grid support, and the top is connected with a cleaning motor 8; the cleaning chamber 7 is arranged on the side of the outer cylinder 5 of the grid support; A row of cleaning brushes 15 is provided; the brush heads of the cleaning brushes 15 penetrate into the protection net cylinder 6; the liquid level transmitter 4 is arranged at the bottom of the protection net ...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that: the control cabinet 3 is provided with an alarm 12 and a control panel 17 . The alarm 12 sends out an audible / optical alarm when the equipment fails or the water level is abnormal; the control panel 17 is used to input control information such as high / low liquid level setting values, and can call to view relevant information of the device.

[0031] The usage method of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0033] The difference between this embodiment and embodiment 2 is that: the bottom of the grid bracket outer cylinder 5 contacts the bottom of the waste water pool 1 , and the top passes through the top of the waste water pool 1 . The bottom of the protective net cylinder 6 is also close to the bottom of the waste water pool 1, which can sense the liquid level in the waste water pool 1 more accurately.

[0034] The usage method of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses an anti-evacuation device for a waste water pool and a use method thereof, comprising a waste water pool, an anti-evacuation protection part and a control cabinet; the waste water pool is provided with a water inlet pipe and a water outlet pipe; the water outlet pipe is connected with a water pump; The anti-evacuation protection part includes a liquid level transmitter, a grid support outer cylinder, a protection net cylinder and a cleaning chamber; the grid support outer cylinder is arranged in a waste water pool; the protection net cylinder is set on the grid support outer cylinder Inside, the top is connected with a cleaning motor; the cleaning chamber is set on the side of the outer cylinder of the grid support; a cleaning brush is provided in the cleaning chamber; the brush head of the cleaning brush penetrates into the protective net cylinder; the liquid The position transmitter is set at the bottom of the protective net cylinder; the control cabinet is equipped with a control system based on PLC; the control system includes a frequency converter and a timer. The invention is cleverly designed, and can control the water pump to output with different powers according to the liquid level, so as to avoid burnout due to evacuation, protect the liquid level sensing device, and avoid the influence of corrosion and large particles of impurities.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and relates to a waste water pool anti-evacuation device and a use method thereof. Background technique [0002] In the production process of electronic aluminum foil, the waste water discharged during the production process needs to be recycled in the waste water tank. A high / low limit switch or a household float switch (hereinafter referred to as a contact element) is installed in a traditional recovery wastewater pool, and is connected to a water pump and other electrical components as an automatic liquid level control device. When the liquid level is high, the high-level contact element is connected, and the water pump starts to pump the liquid away. When the liquid level is low, the low-level contact element is disconnected, and the water pump stops, and the cycle repeats to control the liquid level of the underground pool. However, this kind of device needs to expose and soak...
