Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to a self-cleaning centrifugal pump impeller. Background Art

[0002] A centrifugal pump is a machine that uses the centrifugal force generated by the rotation of the impeller to transport liquids. Centrifugal pumps are widely used in many industries, including chemical, petroleum, medicine, electricity, and food, to transport various media.

[0003] The impellers of traditional centrifugal pumps are generally unable to self-clean, which will lead to performance degradation. The dirt accumulated on the impeller surface will cause the pump performance to deteriorate, the flow rate and head to decrease, and the efficiency to decrease. The dirt increases the flow resistance of the pump, reduces the overall efficiency, increases energy consumption, increases the maintenance frequency, and requires frequent impeller cleaning, which increases the maintenance workload and downtime, increases wear, and accumulates dirt. The wear of the impeller is increased, shortening the service life of the pump. There is a risk of blockage. The dirt may cause the impeller to be partially or completely blocked, affecting the normal operation of the pump.

[0004] In view of this, there is an urgent need for a self-cleaning centrifugal pump impeller to improve the deficiencies of the existing technology. Utility Model Content

[0005] The purpose of the utility model is to provide a self-cleaning centrifugal pump impeller to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a self-cleaning centrifugal pump impeller, including a pump body, the pump body including an outer frame, a block fixedly connected to the inside of the outer frame, the block backflushing water when the water flows rapidly, so that the water can clean the interior after entering the outer frame, one end of the outer frame is fixedly connected to a drive assembly, the drive assembly includes a motor, the motor output shaft is fixedly connected to a runner, the surface of the runner is fixedly connected to blades, and the blades are made of stainless steel.

[0007] As a further improvement of the present technical solution, one end of the outer frame away from the motor is fixedly connected to a water outlet pipe, and one end of the water outlet pipe is fixedly connected to a connecting seat 1, and the connecting seat 1 facilitates connection to the water pipe.

[0008] As a further improvement of the present technical solution, a water inlet pipe is fixedly connected to the surface of the outer frame, the water inlet pipe is communicated with the interior of the outer frame, and one end of the water inlet pipe is fixedly connected to a second connecting seat.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The self-cleaning centrifugal pump impeller can reduce manual cleaning work due to dirt accumulation, thereby reducing maintenance frequency and related costs. The self-cleaning function can keep the impeller in optimal working condition, avoid the decrease in flow and head caused by dirt accumulation, and thus maintain efficient operation. Since the wear of dirt on the impeller and other key components is reduced, the self-cleaning impeller can effectively extend the service life of the pump. The self-cleaning function reduces pump failures caused by impeller blockage or fouling, reduces equipment downtime, and improves system reliability. By automatically removing impurities, the self-cleaning impeller can maintain the stability and reliability of the pump and avoid unstable performance caused by dirt.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example

[0019] See also Figure 1-Figure 3 As shown, this embodiment provides a self-cleaning centrifugal pump impeller, including a pump body 1, the pump body 1 includes an outer frame 10, and a block 13 is fixedly connected to the inside of the outer frame 10. The block 13 backflushes the water when the water flows rapidly, so that the water can clean the inside after entering the outer frame 10. One end of the outer frame 10 is fixedly connected to a drive component 2, and the drive component 2 includes a motor 20. The output shaft of the motor 20 is fixedly connected to a runner 21, and the surface of the runner 21 is fixedly connected to blades 22, and the blades 22 are made of stainless steel.

[0020] The working principle is as follows: first, the device is powered on, and a block 13 is installed inside the outer frame 10. When the pump body 1 is in operation, water flows into the pump body 1 through the inlet of the outer frame 10. Due to the high speed of the water flow, the block 13 will produce a recoil effect under the action of the water flow. This backwash flow can push the water flow to form a certain cleaning effect inside the pump body 1, thereby removing dirt and sediment in the impeller and its surrounding areas, ensuring that the system maintains a good operating condition. A drive component 2 is fixedly connected to one end of the outer frame 10. The motor 20 drives the impeller 21 to rotate through the output shaft. The surface of the impeller 21 is fixed with stainless steel blades 22. These blades 22 generate centrifugal force during rotation, effectively pushing the water flow to various parts of the pump body 1, and at the same time promoting the backwash cleaning process. Since the blades 22 are made of stainless steel, they have excellent corrosion resistance and wear resistance, and can maintain good performance during long-term operation. During the entire work process, the operation of the motor 20 ensures the continuous operation of the impeller 21 and the blades 22, and the backwash water flow further enhances the cleaning effect, ensuring that the impeller and the inside of the pump body 1 remain clean when the centrifugal pump handles fluids containing solid particles or adherent substances, thereby improving the efficiency and service life of the pump.

[0021] In order to facilitate the connection of the water outlet pipe 11, in this embodiment, the end of the outer frame 10 away from the motor 20 is fixedly connected to the water outlet pipe 11, and one end of the water outlet pipe 11 is fixedly connected to a connecting seat 12. The connecting seat 12 facilitates the connection of the water pipe. After the impeller rotates to pump water in, the water flows out through the water outlet pipe 11. A plurality of fixing holes are provided on the surface of the connecting seat 12, and screws are passed through the fixing holes to connect the connecting seat 12.

[0022] In order to facilitate the connection of the water inlet pipe 14, in this embodiment, the water inlet pipe 14 is fixedly connected to the surface of the outer frame 10, the water inlet pipe 14 is connected to the inside of the outer frame 10, one end of the water inlet pipe 14 is fixedly connected to the connecting seat 2 15, the outer frame 10 is fixedly connected to the water inlet pipe 14, and the impeller rotates and pumps water into the outer frame 10 through the water inlet pipe 14.

[0023] When a self-cleaning centrifugal pump impeller in this embodiment is used, the power supply of the device is first turned on, and a block 13 is installed inside the outer frame 10. When the pump body 1 is in working condition, the impeller rotates to pump water in, and the water flows out through the outlet pipe 11. A plurality of fixing holes are provided on the surface of the connecting seat 12, and screws are passed through the fixing holes to connect the connecting seat 12. Due to the fast speed of the water flow, the block 13 will produce a recoil effect under the action of the water flow. This backwash flow can drive the water flow to form a certain cleaning effect inside the pump body 1, thereby removing dirt and sediment in the impeller and its surrounding areas, ensuring that the system remains in good operating condition. A drive assembly 2 is fixedly connected to one end of the outer frame 10, and the motor 20 drives the impeller 21 to rotate through the output shaft. The outer frame 10 is fixedly connected to the water inlet pipe 14. The impeller rotates and pumps water into the outer frame 10 through the water inlet pipe 14. The surface of the impeller 21 is fixed with stainless steel blades 22. These blades 22 generate centrifugal force during rotation, effectively pushing the water flow to various parts of the pump body 1, while promoting the backwash cleaning process. Since the blades 22 are made of stainless steel, they have excellent corrosion resistance and wear resistance and can maintain good performance during long-term operation. During the entire workflow, the operation of the motor 20 ensures the continuous operation of the impeller 21 and the blades 22, and the backwash water flow further enhances the cleaning effect, ensuring that the impeller and the inside of the pump body 1 remain clean when the centrifugal pump handles fluids containing solid particles or adherent substances, thereby improving the efficiency and service life of the pump.
