Description

TECHNICAL FIELD

[0001] The present application relates to the field of cutting pumps, in particular to an adaptive cutting pump. BACKGROUND

[0002] The cutting pump is a sewage treatment equipment for processing sewage containing fibers and hard solids, belonging to the sewage pump category. The cutting pump has a built-in cutting device that can tear impurities such as fibers and cloth strips, and is suitable for high-viscosity liquid delivery. The cutting pump has strong anti-clogging ability, can crush impurities such as fibers and cloth strips, and avoids the problem of easy clogging of traditional sewage pumps. The cutting pump has a long service life, small bearing load, long continuous operation time, and longer service life than general pumps. The cutting pump has low comprehensive maintenance cost. The main application fields of the cutting pump include: farms for processing manure (containing unfermented straw, feed bags), sewage discharge and farmland irrigation; municipal engineering for cleaning pipe network sludge (need to break bricks and tree roots), construction site thin slurry discharge; food processing for delivering fruit and vegetable residues, meat and bone, and sewage discharge and farmland irrigation in construction site and other scenes.

[0003] The cutting pump achieves impurity crushing and delivery through the built-in cutting tool, and has a wide range of applications. However, for hard materials, the cutting tool is difficult to cut, and since the cutting tool is fixed in position, the hard material is easy to get stuck in the cutting tool, which can cause damage to the cutting pump during continuous operation, affecting the service life of the cutting pump. In the utility model patent with the publication number CN215409368U and the name of cutting pump, when the gap between the cutting blade and the cutter head increases due to wear during use, the adjusting screw is removed, the cutter head sleeve is rotated to make the cutter head sleeve close to the cutting blade, and then the adjusting screw is installed back to reduce the gap between the cutter head and the cutting blade, improve the cutting force, and ensure the normal work of the cutting pump and prolong the service life of the cutter head and the cutting blade. However, in the above-mentioned application and existing technology, the gap between the cutter head and the cutting blade needs to be manually adjusted to ensure the shearing force and prevent the hard material from getting stuck in the cutting blade, i.e. the operation needs to be stopped for processing, which has low adaptability and affects the service life of the cutting pump.

[0061] In the technical solution, the fixed cutter 3 can be mounted and dismounted through the mounting bolt groups 7.

[0062] As one of the embodiments of the present application, as shown in Figures 8 to 12 the difference between the other embodiments is that the upper adaptive mechanism comprises a self-regulating assembly 8, the self-regulating assembly 8 comprises a supporting shell 81, the supporting shell 81 is connected with the pump body outer frame shell 1, a rotating regulating plate 82 is arranged at the inner cavity of the supporting shell 81, and the rotating regulating plate 82 is connected to the surface of a rotation transmission mechanism; a plurality of follow-up track rings 83 are connected to the top of the rotating regulating plate 82, the inner side of the follow-up track ring 83 is in sliding connection with the surface of a fixed track 84, the top of the fixed track 84 is connected with the bottom of a mounting ring plate 85, the top of the mounting ring plate 85 is connected with a plurality of anti-disengagement regulating columns 86 arranged in a ring array, the surface of the anti-disengagement regulating column 86 is in slidable through connection with the top surface of the supporting shell 81, the anti-disengagement regulating column 86 is arranged at the inner cavity of a protection cylinder 87, and the bottom of the protection cylinder 87 is connected with the top surface of the supporting shell 81. a plurality of elastic reset members 88 arranged in a ring array are connected to the top of the mounting ring plate 85, the elastic reset member 88 is sleeved on the surface of the anti-disengagement regulating column 86, and the top of the elastic reset member 88 is connected with the inner wall of the top surface of the supporting shell 81.

[0074] In this technical solution, the position of the moving cutting element 4 can be controlled autonomously by using the sliding connection component 10 and the interference component 11, thereby controlling the size of the gap between the fixed cutting element 3 and the moving cutting element 4 as needed.

[0075] In use, a sensor is installed at the cutting pump. When the cutting pump is detected to be malfunctioning, the telescopic device 112 can be used to move the anti-detachment plate 111 upward, which in turn moves the fixed shaft 102 and the moving connecting column 101 in the same direction. This, in turn, moves the moving cutting component 4 in the same direction, increasing the distance between the fixed cutting component 3 and the moving cutting component 4. This allows uncuttable impurities to pass between the fixed cutting component 3 and the moving cutting component 4. After the uncuttable impurities pass through, the telescopic device 112 moves the moving cutting component 4 and other structures back to their initial state, allowing the material to continue to be cut. Example 4

[0076] As one embodiment of this application, such as Figures 16 to 18 As shown, the difference between this and other embodiments is that the cutting unit further includes an auxiliary component 12, which includes a central ring plate 121. The central ring plate 121 is disposed above the moving cutting member 4 and is connected to the surface of the rotary transmission mechanism. An upper ring plate 122 is disposed above the central ring plate 121, and a lower ring plate 123 is disposed below the central ring plate 121. Both the upper ring plate 122 and the lower ring plate 123 are connected to the surface of the rotary transmission mechanism. A plurality of follow rotation bars 124 arranged in a ring array are arranged between the center ring plate 121 and the upper ring plate 122 and between the center ring plate 121 and the lower ring plate 123, and the follow rotation bars 124 are connected to the surface of the rotation transmission mechanism; A first cutting tool 125 is arranged between the center ring plate 121 and the upper ring plate 122, and a second cutting tool 126 is arranged between the center ring plate 121 and the lower ring plate 123, and the first cutting tool 125 and the second cutting tool 126 are respectively arranged in a sliding sleeve manner on the lower ring plate 123 and the surface of the rotation transmission mechanism.

[0077] In the technical solution, the cutting unit can cooperate with the fixed cutting part 3 and the movable cutting part 4 to further cut the material, so as to improve the cutting effect of the material and reduce the probability of blocking the cutting pump.

[0078] In use, the rotation transmission mechanism drives the first cutting tool 125 and the second cutting tool 126 to rotate, and the first cutting tool 125 and the second cutting tool 126 cut the material, thereby assisting the cutting function of the fixed cutting part 3 and the movable cutting part 4, further cutting the material, and improving the cutting effect of the cutting pump.

[0079] The first cutting tool 125 and the second cutting tool 126 move up and down along the rotation mechanism at the moment of rotation, and at this time, the center ring plate 121, the upper ring plate 122 and the lower ring plate 123 can limit the displacement range of the first cutting tool 125 and the second cutting tool 126 respectively, so that the rotation of the first cutting tool 125 and the second cutting tool 126 has a certain randomness, further improving the cutting effect of the material.

[0080] The elastic connecting piece 64 is a spring or other component with elastic reset function.

[0081] The telescopic device 112 is an electric push rod or other device with autonomous telescopic function.

[0082] It is worth noting that the above structures can be arbitrarily combined to form other embodiments.

[0083] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, and the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, and these changes and modifications all fall within the protection scope of the present application.
