Description

Technical Field

[0001] The invention relates to the technical field of mixed flow pump cutting components, in particular to a cutting device for a mixed flow pump. Background Art

[0002] A mixed flow pump is a special type of pump. When the prime mover drives the impeller to rotate, the liquid is acted upon by both centrifugal force and axial thrust. It is a combination of a centrifugal pump and an axial flow pump. The liquid flows out of the impeller obliquely, so it is a pump between a centrifugal pump and an axial flow pump. The specific speed of a mixed flow pump is higher than that of a centrifugal pump, but lower than that of an axial flow pump.

The device can accurately measure the distance between the pump cover plane and the impeller plane through an ultrasonic distance measuring device, thereby avoiding impeller wear, improving the efficiency of the mixed flow pump, and achieving energy-saving effects. However, in actual use, high-pressure water storage equipment is usually required to pump water out. When water enters the mixed flow pump with the assistance of the high-pressure water storage equipment, the water flow usually has a certain impact force due to its pressure difference. The traditional mixed flow pump and the above-mentioned device block the water flow through the pumping blades, and the pumping blades are completely driven by the driving motor to rotate to form suction to pump out the water flow. It is more energy-consuming when pumping large volumes of water. The energy-saving effect of the device has room for further improvement. Summary of the invention

The outer surface of the cutting disk 58 is fixedly connected to a plurality of cutting blades 580 to ensure the normal operation of the device.

[0050] Working principle: After the device is connected to the high-pressure water storage equipment, the high-pressure water storage equipment leads water to the equipment body 2, and the rotary drive component 30 is turned on. The rotary drive component 30 is turned on to drive the rotating shaft 31 to rotate, and the rotating shaft 31 rotates to drive the sealing cylinder 50, the first toothed disc 500, and the fixed rod 33 to rotate. The fixed rod 33 rotates to drive the pumping disc 36 and a plurality of pumping blades 391 to rotate. The pumping blades 391 rotate to pump the water led out of the high-pressure water storage equipment into the inner cylinder 5, and then the mixing sleeve 32 guides the water flow to the axial pipeline of the device to complete the water pumping. In this process, the first toothed disc 500 rotates to drive the two second toothed discs 51 to rotate in the same direction, and the two second toothed discs 51 rotate to drive the two first shafts 52 to rotate. The two first shafts 52 rotate to drive the movable plate 53 and the card plate to rotate. The movable plate 53 rotates through the card plate and the second slide groove 543 to drive the cutting cylinder 54 to rotate, and the cutting cylinder 54 rotates to drive the rotating The disk 56 rotates, and the rotation of the rotating disk 56 drives the rotating column 560 to make a circular motion. The rotating column 560 makes a circular motion and drives the return groove plate 57 to make a linear reciprocating motion. At this time, due to the second shaft rod 570 at the return groove plate 57 for limiting, the return groove plate 57 can no longer make a linear reciprocating motion and can only make a reciprocating swinging motion. The reciprocating swinging motion of the return groove plate 57 drives the cutting disk 58 and the cutting blade 580 to make a reciprocating swinging motion. The two cutting disks 58 make a reciprocating swinging motion to cut the water plants, sludge and other debris in the extracted water flow, so as to avoid the water plants from entering the inner cylinder 5 and entangled with the rotating shaft 31 or the suction disk 36 or large sludge adhering to its surface, which reduces the pumping efficiency of the device. At this time, the device needs to increase the rotation speed of the rotating shaft 31 to maintain normal pumping, thereby increasing the energy consumption of the device, thereby improving the energy saving effect of the device, and the device does not need to be cleaned without adding an additional driving source, which is convenient for users to use;

[0051] When the high-pressure water storage device transports liquid to the low-pressure position, the water flow itself has a certain impact force due to the pressure difference. In the present application, the elastic member 55 is set as a spring and the spring coefficient of the spring is small. At this time, when the water flow enters the inner cylinder 5, it will give pressure to the cutting disk 58 and the cutting cylinder 54. The cutting cylinder 54 moves toward the movable plate 53 under the action of pressure. At this time, the elastic member 55 undergoes elastic deformation to ensure the normal movement of the cutting cylinder 54. The movement of the cutting cylinder 54 drives the connecting plate 541 and the connecting rod 542 to move toward the first toothed disk 500 through the connecting member 540. The connecting rod 54 2 moves to the right, and the cover plate 35 moves to the right, so that the first movable rod 350 moves to the right. The first movable rod 350 moves to the right, and the first piston plate 351 moves to the right in the mounting plate 37. The first piston plate 351 moves to the right, so that the air pressure inside the mounting plate 37 changes. The change in the air pressure inside the mounting plate 37 draws the air inside the plurality of storage cylinders 38 into the mounting plate 37 through the plurality of delivery pipes 370. At this time, the air pressure inside the storage cylinder 38 changes due to the loss of air. The change in the air pressure inside the storage cylinder 38 causes the second piston plate 390 and the second movable rod 350 to move to the right. 39 moves in the direction of the delivery pipe 370, and the movement of the second movable rod 39 drives the pumping blade 391 to shrink relative to the pumping disc 36. The shrinkage of the pumping blade 391 reduces the cross-sectional area of ​​the pumping disc 36, that is, reduces the impact area of ​​the water flow impacting the pumping disc 36, thereby greatly preserving the impact force of the water flow. At this time, the rotary drive component 30 drives the rotating shaft 31 to rotate at a very fast speed to complete the extraction of the water flow. According to the impact force of the water flow, the moving directions of the cutting cylinder 54 and the cover plate 35 are different. When the impact force of the water flow is small, the moving distance of the cover plate 35 is small, and the pumping The contraction distance of the flow blade 391 is small. At this time, the impact force of the water flow and the rotating drive component 30 work together to extract the water flow, thereby reducing the energy consumption of the device. Therefore, the device can spontaneously adjust the cross-sectional area of ​​the flow extraction disk 36 according to the impact force of the water flow, so as to avoid the blocking surface of the device being large when the impact force of the water flow is large due to the external high-pressure water storage device pumping water, thereby offsetting part of the impact force of the water flow, so that the device can only ensure the normal extraction of water flow by increasing the driving power of the driving device 3, thereby increasing the energy consumption of the device, improving the energy-saving effect of the device, and facilitating user use;

[0052] The device does not need to add other driving sources when it is running to complete the effects of extracting water, cutting debris, and adjusting the cross-sectional area of ​​the suction disk 36 according to the impact force of the water flow, thereby reducing the overall energy consumption of the device and reducing the cost of the device, thereby improving the energy-saving effect of the device and facilitating user use.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
