Description

Technical Field

[0001] This utility model relates to the field of vortex pump technology, and in particular to an intelligent low-noise vortex pump. Background Technology

[0002] A vortex pump primarily transfers energy to the liquid by having an impeller inside the pump head continuously apply work to the liquid, creating high pressure and causing it to be ejected from the outlet. Under the action of centrifugal force, the liquid thrown out by the impeller continuously impacts and collides with the inner wall of the pump body and the tongue at the end of the partition wall, thus generating significant noise. Therefore, noise is a problem that urgently needs to be solved in self-priming vortex pumps.

[0003] For example, a patent entitled "A Low-Noise Vortex Pump" (patent application number: CN201810065183.3) discloses a low-noise vortex pump. According to different impeller speeds, the angle of the spring can be adjusted by the control component, thereby minimizing noise and improving the applicability of the vortex pump. However, during use, the angle of the spring needs to be manually adjusted, which is cumbersome and the efficiency needs to be improved.

[0004] Therefore, it is necessary to propose an intelligent, low-noise vortex pump to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent low-noise vortex pump to solve the problem that the angle of the spring needs to be manually adjusted during the use of the vortex pump, which is cumbersome to operate and has low efficiency.

[0007] A circular block is provided at the bottom of the partition cylinder, and the circular block is inclined. A conical block is rotatably provided on the side of the circular block near the impeller. Blades are fixedly installed on the inclined surface of the conical block. An electric push rod is installed at the top of the partition cylinder, and the electric push rod adjusts the angle of the circular block through a transmission assembly.

[0008] A water inlet pipe is connected to the water inlet end, and a pressure sensor is installed on the water inlet pipe.

[0009] Preferably, the blades are provided in multiples, and the multiple blades are evenly distributed around the axis of the cone.

[0010] Preferably, the transmission assembly includes a lifting plate, a first transmission rod, and a second transmission rod. The lifting plate is slidably disposed inside the partition cylinder and is fixedly connected to the telescopic end of the electric push rod. One end of the first transmission rod is hinged to the inner wall of the partition cylinder, and the other end of the first transmission rod is fixedly connected to the circular block. One end of the second transmission rod is hinged to the lifting plate, and the other end of the second transmission rod is hinged to the first transmission rod.

[0011] Preferably, the self-priming cavity is provided with a separation plate, which is parallel to the partition cylinder and close to the impeller.

[0012] Preferably, the self-priming cavity is provided with a baffle plate, which is perpendicular to the partition cylinder and located above the separation plate.

[0013] Preferably, the cone block has a gap with the edge of the impeller.

[0023] This utility model provides, for example Figures 1-4 The diagram shows an intelligent low-noise vortex pump, including a pump body 1. An impeller 5 is installed inside the pump body 1. The impeller 5 is integrally die-cast from a high-strength alloy material, and its blade curvature has been optimized through fluid dynamics simulation, enabling it to efficiently drive liquid flow during rotation. A motor 17 is installed on the side of the pump body 1, which is a permanent magnet high-efficiency high-speed motor. The output speed can be adjusted according to actual working conditions, providing a stable power source for equipment operation. The output shaft of the motor 17 is connected to the central shaft of the impeller 5, ensuring efficient power transmission.

[0024] A baffle 8 is provided above the impeller 5. The baffle 8 is a thin-walled cylindrical structure and is fixed on the inner wall of the pump body 1. The baffle 8 divides the interior of the pump body 1 into a suction chamber and a self-priming chamber. A water inlet 2 and a water outlet 3 are respectively provided on the pump body 1 at the positions corresponding to the suction chamber and the self-priming chamber. The water inlet 2 is connected to the suction chamber and the water outlet 3 is connected to the self-priming chamber to ensure that the liquid can flow according to the preset path.

[0025] A water inlet pipe 4 is connected to the water inlet end 2. The water inlet pipe 4 is made of corrosion-resistant plastic pipe, and its inner diameter matches the diameter of the water inlet end 2.

[0026] The self-priming chamber is equipped with a separation plate 7, which is a rectangular thin plate structure made of stainless steel. The separation plate 7 is parallel to the baffle 8 and is located close to the impeller 5, with its bottom end 10-15 mm away from the top edge of the impeller 5. Both ends of the separation plate 7 are fixedly connected to the inner wall of the pump body 1, which can perform preliminary separation of the gas-liquid mixture in the self-priming chamber and reduce the bubble content in the liquid. The self-priming chamber is also equipped with a baffle plate 6, which is perpendicular to the baffle 8 and located above the separation plate 7. One end of the baffle plate 6 is fixed to the outer wall of the baffle 8, and the other end extends towards the outlet end 3. The baffle plate 6 can further guide and buffer the liquid after separation by the separation plate 7, reduce the liquid flow velocity, reduce the impact and collision between the liquid and the inner wall of the pump body 1, and thus further reduce noise.

[0027] A circular block 13 is provided at the bottom of the partition cylinder 8. The circular block 13 has a circular sheet-like structure (see reference). Figure 3 , Figure 4 The circular block 13 is tilted, with the initial tilt angle set at 30°, which can be adjusted according to actual needs. A cone block 14 is rotatably mounted on the side of the circular block 13 near the impeller 5 via a ball bearing or the like. The cone surface of the cone block 14 faces the edge of the impeller 5, and there is a gap of 5 to 8 mm between the cone block 14 and the edge of the impeller 5. This gap setting can avoid direct contact between the two and cause friction and wear, while ensuring that the fluid can pass through smoothly.

[0028] A blade 15 is fixedly installed on the inclined surface of the cone 14. Multiple blades 15 are provided and are evenly distributed around the axis of the cone 14. The blades 15 adopt an arc design and are fixedly connected to the inclined surface of the cone 14 by welding to form an auxiliary flow guiding structure, which can guide and buffer the liquid thrown out by the impeller 5.

[0029] An electric push rod 9 is installed at the top of the partition cylinder 8, and the electric push rod 9 adjusts the angle of the circular block 13 through the transmission assembly. The transmission assembly includes a lifting plate 11, a first transmission rod 12, and a second transmission rod 16. The lifting plate 11 is a circular plate structure with guide sliders on its edge. A vertical guide groove is correspondingly provided on the inner wall of the partition cylinder 8. The lifting plate 11 is slidably disposed inside the partition cylinder 8 through the cooperation of the guide sliders and the guide grooves (not shown in the figure), ensuring that the lifting process is smooth and without deviation.

[0030] The lifting plate 11 is fixedly connected to the telescopic end of the electric push rod 9, and moves up and down with the telescopic movement of the electric push rod 9. One end of the first transmission rod 12 is hinged to the fixed lug on the inner wall of the partition cylinder 8 by a pin, and the other end of the first transmission rod 12 is fixedly connected to the circular block 13 by bolts. One end of the second transmission rod 16 is hinged to the lifting plate 11, and the other end of the second transmission rod 16 is hinged to the middle position of the first transmission rod 12. Through the cooperation of the first transmission rod 12 and the second transmission rod 16, the linear movement of the lifting plate 11 is converted into the angle adjustment movement of the circular block 13.

[0031] A pressure sensor 10 is installed on the water inlet pipe 4. The pressure sensor 10 is a diffused silicon pressure sensor with an accuracy class of 0.5. It can detect the liquid pressure in the water inlet pipe 4 in real time and convert the pressure signal into an electrical signal, which is then transmitted to an external controller. The external controller is a PLC controller that has pre-stored the angle adjustment parameters of the circular block 13 corresponding to different pressure values. When the detected pressure value changes, the controller automatically sends a control command to the electric push rod 9 to realize the intelligent adjustment of the angle of the circular block 13.

[0032] When the motor 17 is started, the motor 17 drives the impeller 5 to rotate at high speed. During the rotation, the impeller 5 generates centrifugal force, which dissipates the air in the suction chamber and creates a negative pressure in the suction chamber. Under the action of atmospheric pressure, the external liquid enters the suction chamber through the water inlet pipe 4 and the water inlet end 2.

[0033] The pressure sensor 10 on the inlet pipe 4 detects the inlet water pressure in real time and transmits the pressure data to the PLC controller. The controller determines the current liquid flow rate and operating conditions based on the pressure value.

[0034] When the pressure value is too high or too low, the controller sends an action command to the electric push rod 9. The telescopic end of the electric push rod 9 drives the lifting plate 11 to move up and down. The lifting plate 11 pushes the first transmission rod 12 to rotate around the hinge point through the second transmission rod 16, which in turn drives the circular block 13 to adjust the tilt angle. The change in the angle of the circular block 13 will cause the cone block 14 and the blade 15 to deflect synchronously, changing the contact angle between the blade 15 and the liquid thrown out by the impeller 5. The liquid acts on the blade 15, causing the cone block 14 to rotate, thereby guiding and buffering the liquid thrown out by the impeller 5, reducing the impact and collision of the liquid thrown out by the impeller 5 on the baffle 8, and realizing intelligent noise control.

[0035] Compared to using elastic sheets, this method transforms "rigid impact" into "rotational buffering," significantly reducing relative friction with the liquid and providing better buffering and noise reduction.

[0036] After the liquid enters the self-priming chamber, it first undergoes preliminary gas-liquid separation through the separation plate 7. Bubbles rise to the top of the self-priming chamber under buoyancy and are discharged, while the liquid flows towards the outlet end 3 under the guidance of the blades 15. During this flow, the baffle plate 6 further buffers and guides the liquid, reducing turbulence and preventing direct impact on the pipe interface at the outlet end 3, thus further improving noise reduction.

[0037] Through the linkage control of pressure sensor 10 and electric push rod 9, intelligent adaptation between operating conditions and noise reduction structure is achieved, effectively solving the problems of high noise and cumbersome adjustment of traditional vortex pumps, and improving the efficiency and stability of equipment operation.
