[0001] This application relates to the technical field of filter pumps, and specifically to a waste water treatment filter pump. Background Art

[0002] Sewage refers to the discharged water from life and production that has been contaminated to a certain extent. Water that has lost its original use function is simply called sewage. Sewage needs to be treated before it can be discharged.

[0003] The existing patent (publication number: CN218589846U) discloses a filter pump, especially a filter water pump for waste water treatment. The present utility model provides a filter water pump for waste water treatment that can automatically clean the filter cover. A filter water pump for waste water treatment includes a filter water pump, a water outlet pipe, a water inlet pipe, a control box, a timer, an electric push rod, etc.; the water outlet pipe is arranged at the lower part of the filter water pump, the water inlet pipe is arranged at the upper part of the filter water pump, the control box is arranged at the lower part of the filter water pump, the timer is arranged on the control box, the electric push rod is arranged on the filter water pump, a shielding cover is placed on the top of the filter water pump, a collecting ring is arranged on the filter water pump below the shielding cover, and a conical ring is arranged between the filter water pump and the shielding cover.

[0004] The above-mentioned comparative document points out that the device can clean the filter cover regularly by the up and down movement of the conical block to prevent the filter cover from being blocked, and the collecting ring can collect the filtered impurities to prevent the impurities from returning to the water again.

[0005] Aiming at the deficiencies of the prior art, this application provides a waste water treatment filter pump, which has the advantages of being easy to clean the filter water pump, etc., and solves the problem that the device can clean the filter cover regularly by the up and down movement of the conical block to prevent the filter cover from being blocked, and the collecting ring can collect the filtered impurities to prevent the impurities from returning to the water again. However, although the automatic cleaning function reduces the need for manual cleaning, the regular maintenance and replacement of mechanical components such as electric push rods may increase the maintenance cost. The mechanical components may wear or malfunction after long-term operation, which may affect the overall durability and reliability of the equipment.

[0006] To achieve the above object, the present application provides the following technical solution: A wastewater treatment filter pump, comprising a filter water pump, an outer filter frame and an upper cover. A retaining ring is fixedly connected to the inner wall of the filter water pump. An inner filter frame is fixedly connected inside the outer filter frame. A fixing ring is fixedly connected to the upper end of the outer filter frame. A motor is fixedly connected to the upper end of the upper cover. The output end of the motor passes through one end of the upper cover and is fixedly connected to a rotating shaft through a coupling. A rotating block is fixedly connected to the bottom end of the rotating shaft. Three cutting knives arranged in a circumferential array are fixedly connected to the outer wall of the rotating block.

[0007] Through the above solution, the motor drives the rotating shaft and the rotating block, so that the cutting knives fixed on the outer wall of the rotating block can crush the sundries entering the filter water pump, ensuring the continuous and efficient operation of the filter pump, and reducing the performance degradation caused by the blockage of the filter screen by large sundries. The conical setting at the upper end of the inner filter frame helps to guide the wastewater to be better distributed and flow through the filtering area. The conical design can increase the area of the wastewater flowing through the filter screen and improve the filtering efficiency.

[0008] Further, a water inlet pipe is fixedly connected to one side of the upper end of the outer wall of the filter water pump, and a water outlet pipe is fixedly connected to one side of the bottom end of the outer wall of the filter water pump.

[0009] Through the above solution, the clear positions of the water inlet pipe and the water outlet pipe enable the wastewater to smoothly enter the filter water pump for filtration treatment, and then the filtered clear water or treated wastewater can be discharged through the water outlet pipe.

[0010] Further, a base is fixedly connected to the bottom end of the filter water pump.

[0011] Through the above solution, the base provides a stable support platform for the filter water pump. During the wastewater treatment process, the filter water pump needs to bear the pressure from the liquid and the vibration and impact generated during mechanical operation. The base can ensure that the filter water pump remains stable during operation and reduce the risk of performance degradation or damage caused by vibration and shaking.

[0012] Further, a first mounting plate is fixedly connected to the upper end of the filter water pump, and four first mounting holes arranged in a circumferential array are penetrated and opened inside the first mounting plate.

[0013] Through the above solution, the first mounting plate and the first mounting holes on it are not only used for installation, but also enhance the overall structural strength of the filter water pump. They share the stress and vibration generated during the operation of the filter water pump.

[0014] Further, four second mounting holes arranged in a circumferential array are penetrated and opened inside the upper cover, and fixing bolts are slidably arranged inside the four second mounting holes.

[0015] Through the above solution, the combined design of the second mounting hole and the fixing bolt enables the upper cover to be firmly mounted on the filter water pump or other related components. By tightening the fixing bolt, it is possible to ensure a tight fit between the upper cover and the lower structure, forming an effective seal.

[0016] Furthermore, nuts are threadedly connected to one end of each of the four fixing bolts passing through the first mounting hole.

[0017] Through the above solution, by threadedly connecting the nut and the fixing bolt, the connection between the upper cover and the filter water pump or other related components can be made tighter.

[0018] Furthermore, the outer filter frame is slidably arranged inside the filter water pump.

[0019] Through the above solution, the slidable arrangement enables the outer filter frame to be easily taken out and put back inside the filter water pump.

[0020] Furthermore, the three cutting knives are all rotatably arranged inside the filter water pump.

[0021] Through the above solution, the rotatable arrangement of the cutting knives inside the filter water pump may mean that they are used to cut or break solid particles, fibers or other impurities in the wastewater. Through the rotating action of the cutting knives, the size of these impurities can be effectively reduced, making it easier for them to be processed by subsequent filtration equipment.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For this wastewater treatment filter pump, the motor drives the rotating shaft and the rotating block, enabling the cutting knives fixed on the outer wall of the rotating block to crush the sundries entering the filter water pump, ensuring the continuous and efficient operation of the filter pump, reducing the performance degradation caused by the large sundries blocking the filter screen. The conical setting at the upper end of the inner filter frame helps to guide the wastewater to better distribute and flow through the filtration area. The conical design can increase the area of the wastewater flowing through the filter screen, improving the filtration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 In this embodiment, a waste water treatment filtration pump includes a filter water pump 1, an outer filter frame 3 and an upper cover 6. A retaining ring 2 is fixedly connected to the inner wall of the filter water pump 1. An inner filter frame 4 is fixedly connected inside the outer filter frame 3. The conical setting at the upper end of the inner filter frame 4 helps to guide the waste water to better distribute and flow through the filtration area. The conical design can increase the area of the waste water flowing through the filter screen and improve the filtration efficiency. A fixed ring 5 is fixedly connected to the upper end of the outer filter frame 3. A motor 7 is fixedly connected to the upper end of the upper cover 6. The output end of the motor 7 passes through one end of the upper cover 6 and is fixedly connected to a rotating shaft 8 through a coupling. A rotating block 9 is fixedly connected to the bottom end of the rotating shaft 8. Three cutters 10 arranged in a circular array are fixedly connected to the outer wall of the rotating block 9. By driving the rotating shaft 8 and the rotating block 9 by the motor 7, the cutters 10 fixed to the outer wall of the rotating block 9 can crush the sundries entering the filter water pump 1, ensuring the continuous and efficient operation of the filtration pump and reducing the performance degradation caused by the blockage of the filter screen by large sundries.

[0032] Please refer to Figure 1 and Figure 2 On one side of the upper end of the outer wall of the filter water pump 1, a water inlet pipe 11 is fixedly connected. On one side of the bottom end of the outer wall of the filter water pump 1, a water outlet pipe 12 is fixedly connected. The clear positions of the water inlet pipe 11 and the water outlet pipe 12 enable the waste water to smoothly enter the filter water pump 1 for filtration treatment. Subsequently, the filtered clear water or treated waste water can be discharged through the water outlet pipe 12. A base 13 is fixedly connected to the bottom end of the filter water pump 1. The base 13 provides a stable support platform for the filter water pump 1. During the waste water treatment process, the filter water pump 1 needs to bear the pressure from the liquid and the vibration and impact generated during mechanical operation. The base 13 can ensure that the filter water pump 1 remains stable during operation and reduce the risk of performance degradation or damage caused by vibration and shaking.

[0033] Please refer to Figure 1 、Figure 2 and Figure 3 At the upper end of the filter water pump 1, a first mounting plate 14 is fixedly connected. Four first mounting holes 15 arranged in a circular array are penetrated inside the first mounting plate 14. The first mounting plate 14 and the first mounting holes 15 on it are not only used for installation, but also enhance the overall structural strength of the filter water pump 1. They share the stress and vibration generated during the operation of the filter water pump 1. Inside the upper cover 6, four second mounting holes 16 arranged in a circular array are penetrated. Inside each of the four second mounting holes 16, a fixing bolt 17 is slidably arranged. The combined design of the second mounting holes 16 and the fixing bolts 17 enables the upper cover 6 to be stably mounted on the filter water pump 1 or other related components. By tightening the fixing bolts 17, it can ensure the tight fit between the upper cover 6 and the lower structure, forming an effective seal. At one end of each of the four fixing bolts 17 passing through the first mounting holes 15, a nut 18 is threadedly connected. By threadedly connecting the nut 18 and the fixing bolt 17, the connection between the upper cover 6 and the filter water pump 1 or other related components can be made more tight.

[0034] Please refer to Figure 2 and Figure 4 The outer filter frame 3 is slidably arranged inside the filter water pump 1. The slidable arrangement enables the outer filter frame 3 to be easily taken out and put back inside the filter water pump 1. All three cutting knives 10 are rotatably arranged inside the filter water pump 1. The rotational arrangement of the cutting knives 10 inside the filter water pump 1 may mean that they are used to cut or break solid particles, fibers or other impurities in the wastewater. Through the rotational action of the cutting knives 10, the size of these impurities can be effectively reduced, making it easier for them to be processed by subsequent filtration equipment.

[0035] In this embodiment, for this wastewater treatment filter pump, the motor 7 drives the rotating shaft 8 and the rotating block 9, so that the cutting knives 10 fixed on the outer wall of the rotating block 9 can crush the sundries entering the filter water pump 1, ensuring the continuous and efficient operation of the filter pump, and reducing the performance degradation caused by the blockage of the filter screen by large sundries. The conical setting at the upper end of the inner filter frame 4 helps to guide the wastewater to better distribute and flow through the filtration area. The conical design can increase the area of the wastewater flowing through the filter screen and improve the filtration efficiency.

[0036] It should be noted that the upper end of the inner filter frame 4 is conically arranged.

[0037] The working principle of the above embodiment is as follows:

[0038] Wastewater enters the water filter pump 1 through an inlet pipe 11 fixed on the upper end of the outer wall of the water filter pump 1. The position design of the inlet pipe 11 ensures that the wastewater can flow in smoothly. When the wastewater enters the water filter pump 1, the three cutters 10 located inside the water filter pump 1 start to work. These cutters 10 are driven by the motor 7 to rotate the rotating shaft 8 and the rotating block 9. The rotating cutters 10 crush the solid particles, fibers or other large debris in the wastewater to prevent them from clogging the filter screen. This step ensures the continuous and efficient operation of the filter pump. The crushed wastewater then flows through the inner filter frame 4. The conical design of the upper end of the inner filter frame 4 helps to guide the wastewater to be better distributed and flow through the filter area, increasing the area of ​​the wastewater flowing through the filter screen, thereby improving the filtration efficiency, and the impurities in the wastewater are retained by the filter screen , while the filtered clean water or treated wastewater continues to flow downward, and the filtered clean water or wastewater is discharged through the outlet pipe 12 fixed at the bottom end of the outer wall of the water filter pump 1. The position design of the outlet pipe 12 ensures that the treated water can flow out smoothly. During long-term use, the filter screen in the outer filter frame 3 may be blocked due to trapped impurities. At this time, by loosening the nut 18 and removing the fixing bolt 17, the upper cover 6 can be opened for internal maintenance or inspection. The outer filter frame 3 can be removed from the inside of the water filter pump 1 through a sliding setting to clean or replace the filter screen. The water filter pump 1 is firmly supported on the ground by the base 13. The base 13 can reduce the shaking and performance degradation of the water filter pump 1 caused by liquid pressure and mechanical vibration during operation, thereby ensuring the stable operation of the equipment.
