Description

Technical Field

[0001] This utility model relates to the field of filtration mechanism technology, and in particular to a dual-suction pump filtration mechanism with anti-clogging function. Background Technology

[0002] Due to their high head and large flow rate, double-suction pumps are widely used in water supply and drainage systems in mines, cities, and power plants, as well as in farmland drainage and irrigation and various water conservancy projects. During use, it is inevitable that flocculent impurities, silt and other dirt will enter the pump.

[0003] A filter element needs to be installed at the input end of the double-suction pump to prevent flocculent impurities, silt, and other dirt from entering the pump. For example, an energy-saving double-suction pump with an anti-clogging mechanism is disclosed in the prior art Chinese patent announcement number "CN215257024U". This facilitates filtration and anti-clogging, and the anti-clogging mechanism is easy to clean. The pump body has two inlet pipes connected to it. A filter chamber is connected to the inlet pipes via flanges. A cleaning port is opened at the top of the filter chamber. A filter screen is installed at the cleaning port. A sealing plate is connected to the top of the filter screen. The sealing plate is detachably connected to the top of the filter chamber. A cleaning push plate is slidably installed inside the filter chamber. A cleaning brush is connected to the cleaning push plate.

[0004] While most existing dual-suction pump filtration systems can effectively prevent clogging and clean the filter screen, the filtration system is prone to the accumulation of dirt during long-term use. This accumulated dirt is often difficult to remove. In order to clean it thoroughly, the operator has to shut down the dual-suction pump and interrupt its operation. This method is not only inefficient, but may also have an adverse impact on the continuous working environment. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a dual-suction pump filter mechanism with anti-clogging function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a dual-suction pump filtration mechanism with anti-clogging function, including a housing fixedly connected to the input end of the dual-suction pump, two water channels in the middle of the housing, and diversion devices for closing one of the water channels installed at both ends of the housing. A synchronization device for controlling the synchronous rotation of the two diversion devices is provided at the upper end of the housing. A storage frame is formed at the lower end of each of the two water channels. A filter assembly is arranged inside the storage frame. The filter assembly is fixed to the storage frame by a fastener. A locking assembly for fixing the synchronization device is also provided at the upper end of the housing.

[0008] Furthermore, the diversion device includes a diversion plate rotatably connected between the two water channels, and baffles are provided on both sides of the outer casing. The ends of the baffles contact the rotating parts of the diversion plate, and the two baffles are arranged opposite to each other.

[0009] Furthermore, the synchronization component includes two rotating shafts that pass through the housing and are fixedly connected to the diverter plate, and a U-shaped plate that is slidably connected to the upper end of the housing. The upper end of the rotating shaft is fixedly connected to a gear, and teeth are provided on the opposite surfaces at both ends of the U-shaped plate, and the teeth mesh with the gear.

[0010] Furthermore, the filter assembly includes a filter screen, and abutment plates are formed on both sides of the water channel. The filter screen is inserted into and abuts against the abutment plates. A waste box is fixedly connected to the lower side of the filter screen. The waste box is slidably connected in the storage frame. A sealing cap is fixedly connected to the lower end of the waste box.

[0011] Furthermore, the locking assembly includes two opposing plates fixedly connected to one side of the upper end of the housing, and a positioning rod passing through the plates, wherein a spring is fixedly connected between the positioning rod and the plates.

[0012] Furthermore, three holes adapted to the positioning rod are provided on the sides of both ends of the U-shaped plate.

[0013] The present invention proposes a dual-suction pump filter mechanism with anti-clogging function, which has the following advantages: In this invention, a dual-channel structure is set in the middle of the outer shell to effectively divide the water flow. The water channels are adjusted by a diversion device. When a certain water channel needs to be cleaned, the operator only needs to push the synchronization device to seal the diversion plate and the baffle, thereby closing the target water channel and thoroughly cleaning the inside of the water channel without interrupting the normal operation of the dual-suction pump. The filter components can be cleaned while the dual-suction pump is running continuously, which improves work efficiency and facilitates continuous operation. This innovation not only optimizes the maintenance process but also ensures the continuity and stability of the production process. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Reference Figure 1-4 A dual-suction pump filtration mechanism with anti-clogging function includes a housing 1 fixedly connected to the input end of the dual-suction pump. Two water channels 11 are provided in the middle of the housing 1. A diversion device 2 for closing one of the water channels 11 is installed at both ends of the housing 1. A synchronization device 3 for controlling the synchronous rotation of the two diversion devices 2 is provided at the upper end of the housing 1. A storage frame 12 is formed at the lower end of each of the two water channels 11. A filter assembly 4 is provided inside the storage frame 12. The filter assembly 4 is fixed to the storage frame 12 by a fixing member 5. A locking assembly 6 for fixing the synchronization device 3 is also provided at the upper end of the housing 1, wherein the fixing member 5 is a locking buckle.

[0021] It should be noted that the diversion device 2 includes a diversion plate 21 rotatably connected between the two water channels. Both sides of the outer casing 1 are provided with baffles 22. The ends of the baffles 22 are in contact with the rotating parts of the diversion plate 21. The two baffles 22 are arranged opposite to each other. A sealing ring is provided on the baffles 22. Therefore, the diversion plates 21 on both sides abut against the baffles 22, thereby achieving the isolation of one of the water channels 11.

[0022] In this embodiment, the synchronization device 3 includes two rotating shafts 31 that pass through the outer shell 1 and are fixedly connected to the diverter plate 21, and a U-shaped plate 32 that is slidably connected to the upper end of the outer shell 1. A gear 33 is fixedly connected to the upper end of the rotating shaft 31. Teeth 34 are provided on the opposite surfaces at both ends of the U-shaped plate 32. The teeth 34 mesh with the gear 33. A sealing ring is provided where the rotating shaft 31 passes through the outer shell 1 to prevent water from flowing out when the rotating shaft 31 rotates. By pushing the U-shaped plate 32, the teeth 34 and the gear 33 mesh, causing the gear 33 to rotate and drive the diverter plate, thus achieving synchronous and unidirectional rotation.

[0023] Furthermore, the filter assembly 4 includes a filter screen 41, and contact plates 13 are formed on both sides of the water channel 11. The filter screen 41 is inserted into and contacts the contact plates 13. A waste box 42 is fixedly connected to the lower side of the filter screen 41. The waste box 42 is slidably connected in the storage frame 12. A sealing cover 43 is fixedly connected to the lower end of the waste box 42. A sealing ring is provided between the sealing cover 43 and the storage frame 12. The filter screen 41 and the waste box 42 can be removed by opening the fixing piece 5 for cleaning.

[0024] Based on the above embodiments, the locking assembly 6 includes two opposing plates 61 fixedly connected to one side of the upper end of the outer shell 1, and a positioning rod 62 passing through the plates 61. A spring 63 is fixedly connected between the positioning rod 62 and the plates 61.

[0025] The U-shaped plate 32 has three holes on its sides at both ends that are adapted to the positioning rod 62. The positions of the three holes are respectively the sealing of the diversion plate 21 with the left baffle 22, the diversion plate 21 being in the middle position, and the diversion plate 21 being sealed with the right baffle 22.

[0026] Working method: When one of the water channels 11 needs cleaning, pull open the positioning rod 62, and then push the U-shaped plate 32 towards the water channel 11. When the U-shaped plate 32 is pushed, it will cause the gears 33 on both sides to rotate. The gears 33 drive the diversion plate 21 to rotate. When the hole on the U-shaped plate 32 re-engages with the positioning rod 62, the diversion plates 21 on both sides are sealed with the baffle 22. Then open the fixing piece 5 to remove the waste box 42 and the filter screen 41 for cleaning. After cleaning, reinsert the waste box 42 and the filter screen 41 into the storage frame 12 and fix them with the fixing piece 5. Then pull open the positioning rod 62 again and pull the U-shaped plate 32 back. When it is necessary to clean the other water channel 11, simply push the U-shaped plate 32 in the opposite direction and repeat the above steps.

[0027] 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.
