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

[0025] 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

[0031] 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.

[0032] The usage method of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0034] 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.

[0035] The usage method of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses an anti-pumping-out device for a wastewater pool and an application method of the device. The device comprises the wastewater pool, an anti-pumping-out protection part and a control cabinet; the wastewater pool is provided with a water inlet pipe and a water outlet pipe; a water pump is connected to the water outlet pipe; the anti-pumping-out protection part comprises a liquid level transmitter, a grid support outer cylinder, a protection net cylinder and a cleaning cavity; the grid support outer cylinder is arranged in the wastewater pool; the grid support outer cylinder sleeves the protection net cylinder, and a cleaning motor is connected to the protection net cylinder; the cleaning cavity is formed in the side face of the grid support outer cylinder; a cleaningbrush is arranged in the cleaning cavity; a brush head of the cleaning brush penetrates through the interior of the protection net cylinder; the liquid level transmitter is arranged at the bottom of the protection net cylinder; the control cabinet is internally provided with a control system established on the basis of a PLC; the control system comprises a frequency converter and a timer. The anti-pumping-out device is ingenious in design, output of a water pump at different powers can be controlled according to the liquid level, pumping-out burning is avoided, a liquid level sensing device can also be protected, and the influence of corrosion and large-particle impurities is avoided.

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...
