[0002] The daily production and treatment of sewage at the sewage pumping station in the tar refining operation area is often affected by equipment failures, which leads to difficulties in sewage treatment and operation of the sewage pumping station, resulting in serious obstruction of sewage delivery, reduction in the amount of reclaimed water available for reuse at the sewage station, and reduction in industrial water use, affecting industrial production.

[0003] Due to frequent equipment failures and long periods of untreated sewage, sewage stations are overloaded, sewage equipment maintenance costs increase, power consumption increases, industrial sewage treatment costs increase, operators have high labor intensity, sewage discharge efficiency is low, and sewage treatment is unstable.

[0018] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0019] like Figure 1As shown, the working principle of a sewage self-priming control discharge device is: industrial sewage is treated by sedimentation in an underground water pool 3. By the self-priming principle, a centrifugal pump 1 is started when the water storage tank 2 is full of water. The centrifugal pump 1 discharges water. After the water in the water storage tank 2 is discharged, a negative pressure is formed in the tank body to produce a siphon phenomenon to suck the treated water precipitated above the underground water pool 3 into the water storage tank 2. The sewage discharge process is controlled by a series of interlocking to achieve efficient, stable and orderly sewage discharge.

[0020] like Figure 1 As shown, a sewage self-priming control discharge device comprises a centrifugal pump 1, an underground water pool 3, and a water storage tank 2. A water inlet pipe 8 is arranged between the centrifugal pump 1 and the water storage tank 2, and a cut-off valve 6 is arranged on the water inlet pipe 8; a water inlet pipe 5 is arranged at the upper part between the water storage tank 2 and the underground water pool 3. When the centrifugal pump 1 is started, negative pressure is formed after the water storage tank 2 discharges water. Under the siphon effect, the water inlet pipe 5 automatically absorbs water from the underground water pool 3, and sucks and discharges the stationary sewage. The water inlet pipe 5 is provided with a solenoid valve 4, and a vent pipe 13 is arranged at the lower part, and a vent valve 12 is arranged on the vent pipe 13. The underground water pool 3 is provided with a sewage pipe 17, a stop valve 16 is provided on the sewage pipe 17, a water level sensing probe 15 is provided inside the underground water pool 3, an interlocking control I18 is implemented between the solenoid valve 4 and the centrifugal pump 1, the centrifugal pump 1 is started, the solenoid valve 4 is closed, the underground water pool 3 is filled with water into the water storage tank 2, the centrifugal pump 1 is stopped, the solenoid valve 4 is started, the underground water pool 3 is cut off from filling water into the water storage tank 2, and an interlocking control II19 is implemented between the water level sensing probe 15 and the centrifugal pump 1, the water level sensing probe 15 detects the water level of the underground water pool 3 Below the position of the water inlet 14, in order to ensure that the sewage self-priming control discharge device maintains the siphon phenomenon, the water level sensing probe 15 interlocks and controls the centrifugal pump 1 to shut down. When the centrifugal pump is shut down, the solenoid valve 4 on the water inlet pipe 5 is started through the interlock control Ⅰ18 interlock, cutting off the underground water pool 3 from injecting water into the water storage tank 2 to prevent the water in the water storage tank 2 from not being replenished, avoiding the inability to ensure negative pressure in the water storage tank 2 and failing to complete self-priming. The water level sensing probe 15 and the stop valve 16 implement interlock control Ⅲ20, and the water level sensing probe 15 monitors the sewage in the underground water pool 3 When the water level is lower than the water inlet 14, the stop valve 16 is closed through the interlocking control III, and the sewage pipe 17 replenishes water into the underground water tank 3. When the underground water tank 3 reaches the maximum water storage capacity, the stop valve 16 starts to be shut off, the sewage pipe 17 is closed, and the water replenishment to the underground water tank 3 is stopped. The interlocking control I18 to the interlocking control III 20 realize the self-priming, efficient, stable and interlocking control discharge of sewage, which saves the labor intensity of operators, improves the discharge efficiency of sewage, improves the degree of sewage discharge control, reduces the occurrence of device failures, and improves the utilization rate of equipment.

[0021] like Figure 1 As shown, further, the water inlet of the water inlet pipe 5 extends below the liquid surface of the underground water pool 3.

[0022] like Figure 1 As shown, further, a flow regulating valve 11 and a pressure gauge 7 are provided at the outlet of the centrifugal pump 1.

[0023] like Figure 1 As shown, further, the sewage self-treatment and discharge device also includes a water adding pipe 10, and the water adding pipe 10 is arranged on the upper part of the water storage tank 2. A water adding valve 9 is arranged in the water adding pipe 10. The water adding pipe 10 is used when the water storage tank 2 is filled with water for the first time. During other working periods, the water adding valve 9 is closed, and the water adding pipe 10 no longer fills the water storage tank 2 with water.

[0024] like Figure 1 As shown, further, the interlocking control Ⅰ18 is that the centrifugal pump 1 is started, the solenoid valve 4 is disconnected, water flows into the water inlet pipe 5, the centrifugal pump 1 is stopped, the solenoid valve 4 is opened, and water stops flowing into the water inlet pipe 5.

[0025] like Figure 1 As shown, further, the interlocking control II19 is that when the water level sensing probe 15 monitors that the water level is lower than the water inlet 14, the centrifugal pump 1 stops working.

[0026] like Figure 1 As shown, further, the interlocking control III20 is that the water level sensing probe 15 monitors that the water level reaches the maximum water storage capacity, the stop valve 16 is actuated, and the sewage pipe 17 stops taking in water. The water level sensing probe 15 monitors that the water level is lower than the position of the water inlet 14, the stop valve 16 is disconnected, and the sewage pipe 17 takes in water.
