Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sewage treatment pump station, especially to a sewage treatment pump station with energy saving function. BACKGROUND

[0002] Sewage treatment pump station is an important facility in sewage treatment system, which is used for lifting and conveying sewage, and needs huge energy consumption when conveying sewage, so it is necessary to carry out energy saving treatment on the sewage treatment pump station.

[0003] The current sewage treatment pump station, when sewage is conveyed into the pump station, solid impurities will be carried in the sewage, so the filter screen is used to intercept the solid impurities, but when the solid impurities on the filter screen are too much, the mesh of the filter screen will be blocked, which reduces the flow rate of sewage conveying, increases the working time of the sewage treatment pump station, and also increases the energy consumption of the sewage treatment pump station. UTILITY MODEL CONTENTS

[0004] The utility model discloses a sewage treatment pump station with energy saving function to solve the shortcoming in prior art.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the set water inlet pipe, cylinder, connecting plate, baffle, striking block and sealing gasket, when a large amount of solid impurities accumulate on the surface of the filter screen and clog the mesh, the cylinder is activated. The cylinder drives the connecting plate to move, the connecting plate drives the baffle to move, the baffle drives the striking block to move, and the striking block strikes the filter screen, causing the filter screen to vibrate and shake off the solid impurities clogging the mesh. This avoids the situation where the sewage flow rate is reduced due to the mesh clogging, thereby reducing the working time of the sewage treatment pump station, reducing the energy consumption of the sewage treatment pump station, and making it more energy-efficient.

The fixing bolts are then tightened, securing the bent rod in place to prevent the filter screen from being moved by the sewage flow. This facilitates the operator's disassembly of the filter screen, thus enabling convenient maintenance of the pump station. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A wastewater treatment pumping station with energy-saving function includes a pumping station body 1. The outer wall of the pumping station body 1 is fixedly connected to an inlet pipe 2, which can send wastewater into the pumping station body 1. The outer wall of the pumping station body 1 is fixedly connected to the end of a cylinder 3. The cylinder 3 is fixed on the pumping station body 1. The model of the cylinder 3 is selected according to actual needs and can meet the working requirements. The output end of the cylinder 3 is fixedly connected to a connecting plate 4. The cylinder 3 drives the connecting plate 4 to move. The lower end of the connecting plate 4 is fixedly connected to a baffle 5. The length of the baffle 5 is greater than the upper sliding surface of the inlet pipe 2. The length of the groove ensures that the connecting plate 4 will block the chute no matter how it moves, preventing sewage leakage. The connecting plate 4 drives the baffle 5 to move. The outer wall of the connecting plate 4 is slidably connected to the inlet pipe 2 through the chute. The connecting plate 4 slides on the inlet pipe 2. The outer wall of the baffle 5 is equipped with a sealing gasket 8, which can prevent sewage from flowing out from the gap between the inlet pipe 2 and the baffle 5. The outer wall of the baffle 5 is slidably connected to the inlet pipe 2 through the chute. The baffle 5 slides inside the inlet pipe 2. The lower end of the baffle 5 is fixedly connected to the striking block 6. The baffle 5 drives the striking block 6 to move. When a large amount of solid impurities accumulate on the surface of the filter screen 9 and clog the mesh, the cylinder 3 is activated. The cylinder 3 drives the connecting plate 4 to move, the connecting plate 4 drives the baffle 5 to move, and the baffle 5 drives the striking block 6 to move. The striking block 6 strikes the filter screen 9, causing the filter screen 9 to vibrate and shake off the solid impurities clogging the mesh. This avoids the situation where the sewage flow rate decreases due to the mesh clogging, thereby reducing the working time of the sewage treatment pump station, reducing the energy consumption of the sewage treatment pump station, and making it more energy-efficient.

[0024] In this embodiment, the inner wall of the inlet pipe 2 is in contact with the filter screen 9. The filter screen 9 can intercept solid impurities in the sewage, performing initial purification treatment on the sewage. The lower end of the filter screen 9 is fixedly connected to the bent rod 10, which fixes the position of the filter screen 9. The outer wall of the bent rod 10 passes through a through hole through the flange mounted on the surface of the inlet pipe 2. The bent rod 10 is inserted into the through hole below the inner wall of the flange at the end of the inlet pipe 2. A fixing bolt 11 is movably passed through the through hole on the outer wall of the bent rod 10. The fixing bolt 11 can fix the position of the bent rod 10 where it passes through the flange. The end of the fixing bolt 11 is threadedly connected to the outer wall of the inlet pipe 2. The fixing bolt 11 fixes the position of the bent rod 10, so that the lower end of the bent rod 10 always passes through the flange. This ensures that the filter screen 9 remains in the same position and does not move. A ladder 12 is installed on the outside of the pump station body 1, which allows operators to easily climb up the pump station body 1 for maintenance. A railing 13 is installed at the top of the pump station body 1 to prevent operators from falling from above the pump station body 1. The outer wall of the pump station body 1 is fixedly connected to the drain pipe 15, which can discharge the sewage stored inside the pump station body 1. A soft pad 7 is installed at the end of the striking block 6 to reduce the impact of the striking block 6 on the filter screen 9 and prevent the filter screen 9 from deforming. A top cover 14 is installed at the top of the pump station body 1, which allows operators to observe the inside of the pump station body 1 from above.

[0025] The working principle of this embodiment is as follows: In use, firstly, the flange on the surface of the inlet pipe 2 is connected to the external sewage source. Then, the flange on the outside of the drain pipe 15 is connected to the water pipe of the subsequent sewage treatment process. After the connection is completed, the sewage is pumped into the pump station body 1 through the inlet pipe 2 by an external water pump. When the sewage passes through the filter screen 9, solid impurities in the sewage are intercepted at the filter screen 9. When the mesh of the filter screen 9 is blocked by solid impurities, causing the sewage flow rate to decrease, the external power supply of the cylinder 3 is turned on, and the cylinder 3 is started. The cylinder 3 drives the connecting plate 4 to move, the connecting plate 4 drives the baffle 5 to move, and the baffle 5 drives the striking block 6 to move. The striking block 6 strikes the filter screen 9, causing the filter screen 9 to vibrate and shake off the solid impurities blocking the mesh. This avoids the situation where the sewage flow rate decreases due to the mesh blockage, thereby reducing the working time of the sewage treatment pump station, reducing the energy consumption of the sewage treatment pump station, and making it more energy-efficient. When there are too many solid impurities, the impact force of the solid impurities on the filter screen 9 increases, and the filter screen 9 deforms under the impact, requiring replacement. When this happens, the operator removes the external water pipe connected to the inlet pipe 2, then unscrews the fixing bolt 11. The fixing bolt 11 no longer restricts the position of the bent rod 10. Then the operator moves the bent rod 10 out of the flange through hole, thereby removing the filter screen 9 from the inlet pipe 2. Then the new filter screen 9 is placed in the inlet pipe 2, so that the lower end of the bent rod 10 is inserted into the flange through hole, and the fixing bolt 11 is tightened. The fixing bolt 11 fixes the position of the bent rod 10, preventing the filter screen 9 from moving when the sewage flows. This makes it easy for the operator to replace the filter screen 9 and facilitates maintenance. When it is necessary to transport the sewage stored in the pump station body 1 to the next process, the sewage in the pump station body 1 is discharged from the drain pipe 15 by the external water pump, completing the drainage work of the sewage treatment pump station.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
