BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural diagram of an embodiment of the utility model.

[0017] The figure includes: stop valve 1, cylinder 2, water outlet pipe 3, check valve 4, water pump 5, collection area 6, orifice plate 7, solenoid valve 8, drainage pipe 9, flushing pipe 10, grille 11, and liquid level sensor 12. DETAILED DESCRIPTION

[0018] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1As shown, an integrated prefabricated pump station with slag removal and self-cleaning functions according to an embodiment of the utility model includes a cylinder 2, a water outlet pipe 3, a water pump 5, a grille 11, a flushing unit and a collecting unit; the water pump 5 is arranged inside the cylinder 2 and is located at the lower part; one end of the water outlet pipe 3 is connected to the water pump 5, and the other end passes through the side wall of the cylinder 2 and extends to the outside of the cylinder 2; the grille 11 is arranged on the side wall of the cylinder 2; the flushing unit is arranged on the water outlet pipe 3; the collecting unit is arranged inside the cylinder 2.

[0020] In the above-mentioned integrated prefabricated pump station with slag removal and self-cleaning functions, a flushing unit is provided, and the flushing unit is provided on the outlet pipe 3. Before the water pump is operated, the flushing unit backwashes the bottom of the cylinder 2 through the water stored in the outlet pipe 3, so that the sludge deposited at the bottom of the cylinder 2 is washed and mixed with the water to form a mixed liquid, and then the water pump 5 is turned on to discharge the mixed liquid from the cylinder 2 through the water pump 5 and the outlet pipe 3, so that the water inlet of the water pump 5 will not be blocked by the sludge during operation; by providing a collecting unit, the water entering the cylinder 2 first flows through the bottom of the cylinder 2, and the floating objects in the water are collected in the collecting area 6 through the collecting unit, and then the floating objects are discharged from the cylinder 2 through the water pump 5 and the outlet pipe 3, and the floating objects in the water can be discharged from the cylinder 2 in a timely and rapid manner. The water pump 5 is ensured to operate safely and reliably.

[0021] When the pump station is not in operation, the stop valve 1 is in an open state, and the solenoid valves 8 are in a closed state. At this time, a certain height of residual water remains in the water outlet pipeline 3.

[0022] When sewage enters the water inlet of the pump station, the screen 11 separates the sewage containing impurities, and the impurities larger than the gap of the screen 11 are intercepted, and the impurities smaller than the gap of the screen 11 enter the drainage pipe 9 along with the sewage, and the drainage pipe 9 transports the sewage to the collection area 6, and the sewage flows upward through the filter holes of the orifice plate 7. When the liquid level reaches the starting liquid level of the water pump 5, the liquid level sensor 12 transmits a signal to the control system, and the control system opens the solenoid valve 8. At this time, the remaining water in the outlet pipe 3 enters the water pump through the flushing pipe 10, and drives the impeller to reverse, so that the backflowing water flows downward through the water inlet of the water pump 5 to impact the sludge at the bottom of the cylinder 2, so that the sludge is diluted into a mixed liquid.

[0023] After the sludge at the bottom of the cylinder 2 is flushed, the control system closes the solenoid valve 8 and starts the water pump 5 at the same time. At this time, the water pump 5 discharges the mixed liquid out of the cylinder 2 through the water outlet pipe 3.

[0024] At the same time, the water pump 5 sucks the water in the collection area 6. The particles and floating objects in the collection area 6 cannot pass through the filter holes on the orifice plate 7 and are intercepted by the orifice plate 7. Then, they are sucked into the water pump 5 along with the water and discharged from the cylinder 2 through the water outlet pipe 3. At this time, when the water pump 5 is running, the water inlet will not be blocked by sludge, and the floating objects in the water can be discharged from the cylinder 2 in time, ensuring that the water pump 5 can operate safely and reliably.

[0025] When the liquid level in the cylinder drops to the shutdown level of the water pump, the control system shuts down the water pump 5, so that some residual water remains in the outlet pipe 3 for flushing the sludge at the bottom of the cylinder 2 next time.

[0026] As a preferred example, the flushing unit includes a stop valve 1, a check valve 4, a solenoid valve 8 and a flushing pipe 10; the stop valve 1 and the check valve 4 are both arranged on the outlet pipe 3; the water inlet and outlet ends of the flushing pipe 10 are both connected to the outlet pipe 3; the check valve 4 is arranged on the outlet pipe 3 near the outlet of the water pump 5; the check valve 4 is located between the water inlet and outlet ends of the flushing pipe 10; the solenoid valve 8 is arranged on the flushing pipe 10. By setting up the flushing unit, before the pump station is operated, the sludge at the bottom of the cylinder 2 is flushed by the residual water in the outlet pipe 3, so that the sludge is diluted into a mixed liquid, so as to avoid the sludge blocking the water inlet of the water pump 5 and ensure the stable operation of the water pump 5.

[0027] As a preferred example, the check valve 4, the solenoid valve 8 and the flushing pipe 10 are all arranged inside the cylinder 2; when the water pump 5 is running, the solenoid valve 8 is in a normally closed state. The check valve 4 is arranged inside the outlet pipe 3 and at the lower part, so that more residual water in the outlet pipe 3 can be stored, so that the flushing effect of the sludge at the bottom of the cylinder 2 can be better. The check valve 4 is a one-way valve, and the water can pass through the check valve 4 from the water outlet of the water pump 5, flow through the outlet pipe 3 and then be discharged; the water in the outlet pipe 3 cannot flow back into the water pump 5 through the check valve 4. When the pump station is running, the solenoid valve 8 is closed, so that the sewage can be smoothly discharged from the cylinder 2 through the outlet pipe 3.

[0028] As a preferred example, the water outlet pipe 3 passes through the upper part of the side wall of the cylinder 2 and extends to the outside of the cylinder 2; the stop valve 1 is arranged on the water outlet pipe 3 outside the cylinder 2; when the water pump 5 is running, the stop valve 1 is in a normally open state. The water outlet pipe 3 passes through the upper part of the side wall of one side of the cylinder 2 and extends to the outside of the cylinder 2; the stop valve 1 is arranged on the water outlet pipe 3 outside the cylinder 2, so that more water can be retained, and the flushing effect can be further enhanced.

[0029] As a preferred example, the collection unit includes a collection area 6, a perforated plate 7 and a drainage pipe 9; the perforated plate 7 is arranged at the bottom of the cylinder 2; the collection area 6 is arranged below the perforated plate 7; one end of the drainage pipe 9 is connected to the grid 11, and the other end is inserted into the collection area 6 below the perforated plate 7. The collection unit allows the sewage filtered by the grid 11 to flow to the bottom of the cylinder 2, and performs secondary filtration on the sewage at the bottom of the cylinder 2, so that the floating objects are trapped at the bottom of the cylinder to ensure that they are discharged from the cylinder in time by the water pump.

[0030] As a preferred example, the orifice plate 7 is adapted to the cylinder 2, and the orifice plate 7 is connected to the side wall of the cylinder 2; the orifice plate 7 is provided with evenly distributed filtering holes. The orifice plate 7 is located below the starting liquid level of the water pump; the orifice plate 7 is adapted to the cylinder 2 to ensure that floating debris in the sewage will not pass through the orifice plate 7 to reach the cylinder 2 above the orifice plate 7, so that the floating debris is trapped in the collection area 6 and then discharged in time through the water pump 5.

[0031] As a preferred example, a collection area 6 is formed between the orifice plate 7 and the bottom of the cylinder 2; the water inlet of the water pump 5 is arranged in the collection area 6, and the water inlet of the water pump 5 is located at the highest point of the collection area 6. The water inlet of the water pump 5 is located at the highest point of the collection area 6 so that floating objects can be sucked into the water pump 5 more quickly and smoothly along with the sewage and discharged from the cylinder 2 through the outlet pipe 3.

[0032] As a preferred example, the orifice plate 7 is tilted downward from the center to the surroundings; the height of the center position of the orifice plate 7 is higher than the height of the surroundings. The orifice plate 7 is tilted downward; when the water pump 5 is running, the high-speed rotating impeller draws the water in the collection area 6 into the pump, and the water pump 5 is set in the highest area of ​​the collection area 6, that is, at the center of the orifice plate 7. At this time, the floating objects follow the water flow along the lower part of the tilted orifice plate and quickly enter the water inlet of the water pump 5 without hindrance. At the same time, the water body on the upper part of the orifice plate pushes the floating objects downward through the holes, accelerating the flow of the floating objects to the inlet of the water pump, so as to be quickly discharged from the cylinder.

[0033] As a preferred example, an integrated prefabricated pump station with slag removal and self-cleaning functions further includes a liquid level sensor 12; the liquid level sensor 2 is arranged on the top inner wall of the cylinder 2. The liquid level sensor 12 is used to detect the height of the liquid level in the cylinder.

[0034] As a preferred example, the water outlet pipe 3 and the grille 11 are arranged on the side wall of the cylinder 2. Water enters the cylinder 2 from one side of the grille 11 of the cylinder 2, passes through the water pump 5, and is discharged through the water outlet pipe 3 on the other side of the cylinder 2. The overall device has a complete structure and stable operation.
