Description

Technical Field

[0001] This utility model relates to the field of pre-pump filtration technology, specifically a water flow-driven rotary device. Background Technology

[0002] A pump filter is a device used in pipelines that transport media. Pump filters are generally used at the water pump suction port to prevent impurities from entering the pump and damaging the pump parts. At the same time, when the pump is stopped, it can prevent the water in the pump from flowing back, avoiding the need to fill the pump with water and vent it when restarting the pump.

[0003] To prevent filter cartridge clogging, existing pre-pump water-floating filters typically drive the filter cartridge to rotate and use high-pressure water jets to flush it. Currently, most of these filters use electric motors to drive the filter cartridge rotation. However, electric motors are expensive and pose safety hazards. Furthermore, the lifespan of the bearings is reduced in harsh environments, which in turn affects the lifespan of the water flow-driven rotation device. Therefore, we provide a water flow-driven rotation device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a water flow-driven rotating device. This solution utilizes the power generated by the water pump to drive the filter cartridge to rotate, thus eliminating the need for an additional drive motor to achieve continuous rotation of the filter cartridge. It controls the rotation speed solely by the water flow rate, featuring energy saving, safety, and high efficiency. Furthermore, it employs a sealed deep groove ball bearing to reduce the resistance during filter cartridge rotation, thereby ensuring the service life of the bearing and extending the service life of the water flow-driven rotating device. At the same time, the components within the water flow-driven rotating device have low cost and simple manufacturing process, thereby reducing production costs and offering a high cost-performance ratio.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water flow driven rotation device, comprising an outer ring, a flange fixedly connected to the outer surface of the outer ring, an inner ring disposed inside the outer ring, a plurality of blades installed on the inner wall of the inner ring and fixedly connected to the outer ring, a detachable support ring slidably assembled inside the inner ring, a bearing embedded inside the support ring, and a central shaft tube fixedly connected to the inner ring of the bearing.

[0006] Furthermore, the outer surfaces of both the inner ring and the support ring are provided with a number of mounting holes arranged in a circle. The mounting holes on the inner ring and the support ring are in corresponding positions, so that a stable connection between the inner ring and the support ring can be achieved by using fasteners such as pins or bolts.

[0007] Furthermore, the blades are arranged in a circular pattern and evenly distributed on the outer surface of the inner ring. The circular arrangement of the blades allows the power generated by the water pump to impact the blades evenly, thereby improving the stability of the filter cartridge of the water-floating filter before the pump when it rotates.

[0008] Furthermore, the bearing is a sealed deep groove ball bearing, which can withstand large radial and axial loads and has high speed capability. It is suitable for various high-speed rotating equipment, and has low friction loss and high efficiency. At the same time, the sealed design can prevent the lubricating grease inside the bearing from overflowing, thereby extending the service life of the bearing.

[0009] Furthermore, the inner ring and the support ring are fixed together by bolts or pins. The bolts or pins are passed through the mounting holes opened on the inner ring and the support ring at the same time, thereby achieving a stable connection between the inner ring and the support ring. Users can make the appropriate selection according to their needs, thereby improving the convenience of use.

[0010] Compared with existing technologies, this water flow-driven rotary device has the following advantages:

[0011] 1. This utility model can use the power generated by the water pump to drive the filter cartridge to rotate, thus eliminating the need for an additional drive motor to achieve continuous rotation of the filter cartridge. The rotation speed is controlled solely by the water flow rate, which is energy-saving, safe, and efficient. Furthermore, the use of sealed deep groove ball bearings reduces the resistance during the rotation of the filter cartridge, thereby ensuring the service life of the bearings and extending the service life of the water flow driven rotation device. At the same time, the components of the water flow driven rotation device have low cost and simple manufacturing process, which can reduce production costs and has a high cost performance.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] As described in the background art, existing pre-pump water-floating filters typically drive the filter cartridge to rotate and use high-pressure water jets to flush the filter cartridge in order to prevent it from clogging. Currently, most of them use motors to drive the filter cartridge to rotate. However, motor drives are expensive and pose safety hazards. In addition, the service life of bearings will be reduced in harsh environments, which will affect the service life of the water flow driven rotation device. Therefore, this embodiment provides a water flow driven rotation device.

[0021] See Figures 1 to 5 This embodiment proposes a water flow driven rotation device, including an outer ring 1, a flange 2 fixedly connected to the outer surface of the outer ring 1, an inner ring 3 disposed inside the outer ring 1, and a plurality of blades 4 installed on the inner wall of the inner ring 3, and the blades 4 being fixedly connected to the outer ring 1.

[0022] Flange 2 is fixed to the outer surface of outer ring 1, and bolts can be used to install flange 2 in the use position. Blade 4 can be inserted into the reserved slot opened on inner ring 3, and the number of blades 4 can be increased or decreased according to the actual situation. At the same time, blade 4 is welded to the inner wall of outer ring 1, thereby realizing the integration of outer ring 1, inner ring 3 and blade 4 into a whole.

[0023] The blades 4 are arranged in a circular pattern and evenly distributed on the outer surface of the inner ring 3. The circular arrangement of the blades 4 enables the power generated by the water pump to impact the blades 4 evenly, thereby improving the stability of the filter cartridge of the water-floating filter in front of the pump when it rotates.

[0024] The inner ring 3 has a detachable support ring 5 that slides inside. The support ring 5 has a bearing 6 embedded inside. The inner ring of the bearing 6 is fixedly connected to a central shaft tube 7.

[0025] The support ring 5 is slidably mounted inside the inner ring 3, the bearing 6 is embedded inside the support ring 5, and the inner ring of the bearing 6 is fixed to the outer surface of the central shaft tube 7. Thus, the bearing 6 can be used to reduce the resistance when the filter cartridge of the water-floating filter in front of the pump rotates, and the central shaft tube 7 is connected to the central rod on the water-floating filter in front of the pump.

[0026] Bearing 6 is a sealed deep groove ball bearing, which can withstand large radial and axial loads and has high speed capability. It is suitable for various high-speed rotating equipment, and has low friction loss and high efficiency. At the same time, the sealed design can prevent the lubricating grease inside bearing 6 from overflowing, thereby extending the service life of bearing 6.

[0027] Both the inner ring 3 and the support ring 5 have several mounting holes 8 arranged in a circle on their outer surfaces. The inner ring 3 and the support ring 5 are fixed together by bolts or pins. The bolts or pins are passed through the mounting holes 8 on the inner ring 3 and the support ring 5 at the same time, so as to achieve a stable connection between the inner ring 3 and the support ring 5. Users can make the appropriate selection according to their needs, thereby improving the convenience of use.

[0028] The components in the accompanying drawings of this utility model are for styling reference only and are not specific dimensional standards. The specific dimensions are determined according to the actual production requirements. In addition, the components are preferably made of stainless steel, which can extend the service life while ensuring structural strength. The materials of the components can also be replaced according to actual needs.

[0029] Working principle: Several blades 4 are sequentially inserted into the pre-reserved slots on the inner ring 3, and the outer ring 1 and the inner walls of the blades 4 are connected by welding. Then, the support ring 5 and the central shaft tube 7 are connected to the outer surface of the bearing 6 and the inner ring, respectively. Next, the support ring 5 is slid into the inner ring 3. Then, bolts or pins are simultaneously passed through the mounting holes 8 on both the inner ring 3 and the support ring 5 to achieve a stable connection between the inner ring 3 and the support ring 5, thus forming a complete water flow driven rotary device. Finally, bolts are passed through the pre-reserved holes on the flange 2 to connect the water flow driven rotary device to the pre-pump water-floating filter. In subsequent use… The power generated by the water pump impacts the blades 4, causing them to rotate. This, in turn, drives the filter cartridge of the upstream water-floating filter to rotate, eliminating the need for an additional drive motor. The rotation speed is controlled solely by the water flow rate, offering energy efficiency, safety, and high performance. Furthermore, the use of sealed deep groove ball bearings 6 reduces resistance during filter cartridge rotation, ensuring the bearings' lifespan and extending the lifespan of the water flow-driven rotation device. Additionally, the components within the water flow-driven rotation device are low-cost and simple to manufacture, reducing production costs and resulting in a high cost-performance ratio.
