Abstract

The present application relates to the technical field of sewage pumps, in particular to a non-clogging sewage pump, which includes: a main body assembly, including a driving motor, a pump body and a chamber; a motion assembly, including an impeller and a transmission shaft; an adjusting component is arranged at the end of the impeller. When the viscosity of the flowing medium inside the chamber is relatively high or the particulate content is relatively large, affecting the rotational speed of the impeller, the adjusting component moves the impeller upward inside the chamber, increasing the medium flow space, reducing the friction and collision between the fluid and the pump body and the impeller, reducing clogging and wear. When the viscosity of the sewage inside the chamber is low and the particulate content is small, the rotational speed of the impeller is relatively fast, and it is located at a lower position inside the chamber, close to the water inlet, which can make the fluid enter the impeller more smoothly. When the impeller rotates, it can drive the fluid more fully, increasing the flow rate of the pump. At the same time, a cutting component is located inside the chamber, and the fixed blades in the fixed ring cooperate with the cutting blades on the movable ring to cut and crush the solid particles entering the chamber, effectively avoiding clogging inside the pump body.

Description

Technical Field

[0001] This application relates to the technical field of sewage pumps, and particularly to a non-clogging sewage pump. Background Art

[0002] The impeller design of traditional sewage pumps is relatively conventional. When facing sewage containing a large amount of solid particles, such as construction waste, industrial waste residues, and domestic garbage fragments, the solids are extremely likely to get stuck in the gap between the impeller and the pump body, causing the impeller to jam and the pump to malfunction. For substances containing long fibers, such as fiber bundles in textile wastewater and papermaking sewage, they are extremely likely to wind around the impeller and become tighter over time. This not only reduces the pumping efficiency of the pump but also destroys the dynamic balance of the impeller, causing vibration of the pump body and shortening the service life of the equipment.

[0003] The patent application with the publication number CN118462598A discloses a non-clogging and non-sealed self-priming sewage pump, which includes a pump body, a motor installed at the top of the pump body, and a shaft structure installed at the output end of the motor and extending into the pump body. An inlet assembly for filtering solid particles is installed on one side of the pump body. An impeller assembly is fixedly sleeved on the outer surface of the shaft structure. A positioning and intercepting assembly for cooperating with the impeller assembly to shear the winding objects entering the pump body is installed on the inner wall of the pump body. The positioning and intercepting assembly includes reinforcing strips installed on the inner wall of the pump body and arranged obliquely, and intercepting strips with a wider upper part and a narrower lower part and arranged vertically and horizontally misaligned are installed at both ends of the reinforcing strips. This technical solution can perform fine segmentation operations on the fibrous winding objects entering the pump body, thereby reducing the length of the winding objects and thus reducing the subsequent damage to the impeller. And it can filter the middle and lower layers of the sewage flow, effectively intercepting most hardened substances and avoiding complete blockage of the pipeline.

[0004] However, there are still some problems with this technical solution: Although this technical solution can achieve crushing and cutting of objects, it still cannot effectively solve the blockage caused by too high viscosity of the fluid medium and too many carried particulate matters.

When the viscosity of the sewage inside the chamber is low and the particulate content is small, the rotation speed of the impeller is relatively fast and it is located at a relatively low position inside the chamber, close to the water inlet, which can make the fluid enter the impeller more smoothly. When the impeller rotates, it can drive the fluid more fully, increasing the flow rate of the pump. At the same time, the cutting member is located inside the chamber. The fixed blades in the fixed ring cooperate with the cutting blades on the movable ring to cut and crush the solid particles entering the chamber, effectively avoiding clogging inside the pump body. When the cutting member encounters particles that cannot be cut, the cutting blades will flip, expanding the gap to allow the particles to pass through, avoiding damage to the blades and ensuring normal subsequent cutting work.

[0032] To make the above objects, features and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings of the specification.

[0033] In the following description, many specific details are set forth to fully understand the present application. However, the present application can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0034] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present application. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0035] Embodiment 1

[0036] This is the first embodiment of the present application, which provides a non-clogging sewage pump.

[0037] Specifically, referring to Figures 1 to 4 , the main body assembly 100 includes a driving motor 101, a pump body 102 provided at the end of the driving motor 101, and a chamber 103 provided on the inner wall of the pump body 102;

[0038] The moving assembly 200 provided inside the chamber 103 includes an impeller 201 and a transmission shaft 202 provided at the axis of the impeller 201. A cutting member is provided at the end of the transmission shaft 202 for shredding solid particles to prevent clogging. At the same time, an adjusting member is provided at the end of the impeller 201. The adjusting member adjusts the height of the impeller 201 on the inner wall of the chamber 103 according to the rotation speed of the impeller 201 on the inner wall of the chamber 103, so as to increase the fluid flow space when clogging occurs in the chamber 103 or when discharging sewage with high-viscosity medium.

[0039] Among them, the cutting component is located inside the chamber 103. When the driving motor 101 is started, sewage enters the chamber 103 at the center of the pump body 102 through the water inlet 1021 at the bottom of the pump body 102 and is discharged outward through the water outlet 1022 communicating with the upper part of the chamber 103. At this time, the sewage will enter the inside of the chamber 103 after passing through the cutting component. The cutting component cuts the solid particles in the sewage to avoid blockage. At the same time, when the cutting component encounters particles that cannot be cut, it will undergo an adaptive change to allow the particles to pass through, avoiding damage to the blades.

[0040] The connector 1011 provided on the driving motor 101 and the transmission shaft 202 adopt an electromagnetic coupling method to avoid damage to the driving motor 101 when the impeller 201 cannot rotate inside the pump body 102. At the same time, the adjusting component at the end of the impeller 201 is affected by the rotation of the impeller 201 inside the chamber 103. When the viscosity of the medium flowing inside the chamber 103 is relatively high or the content of particulate matter is relatively large, which affects the rotation speed of the impeller 201, at this time, the adjusting component causes the impeller 201 to move upward inside the chamber 103, increasing the space for the medium to flow inside the chamber 103. The larger flow space can reduce the friction and collision between the fluid and the pump body 102 and the impeller 201, reducing blockage and wear.

[0041] Embodiment 2

[0042] This is the second embodiment of this application, which is implemented based on the previous embodiment.

[0043] Specifically, referring to Figures 8 to 10 , the adjusting component includes a connecting plate 301. The connecting plate 301 is fixed to the end of the impeller 201 and sleeved on the outer wall of the transmission shaft 202. The end face of the connecting plate 301 is provided with movable rods 3011 in an array. The inner wall of the movable rod 3011 is provided with a connecting platform 3013, and the end face of the connecting platform 3013 is provided with a second elastic member 3014. One end of the second elastic member 3014 is fixed to the end face of the connecting plate 301 to pull the movable rod 3011 to move inward.

[0044] Among them, the connecting plate 301 is fixed on the upper surface of the impeller 201 and rotates synchronously with the impeller 201. The movable rods 3011 arrayed on the surface of the connecting plate 301 are pulled by the second elastic member 3014 on the surface and move closer to the transmission shaft 202 when the rotation speed of the connecting plate 301 is relatively low. When the rotation speed of the impeller 201 is relatively high, under the action of centrifugal force, the movable rod 3011 overcomes the pulling force of the second elastic member 3014 and opens outward.

[0045] Preferably, referring to Figure 8 、 Figure 9, a control console 302 is sleeved on the outer wall of the connecting plate 301, and a concave surface 3021 is provided on the inner wall of the control console 302. The concave surface 3021 cooperates with a convex surface 3012 provided on the outer wall of the movable rod 3011. When the convex surface 3012 contacts the concave surface 3021, the control console 302 is driven by the movable rod 3011 to rotate at the end of the impeller 201.

[0046] Among them, the control console 302 is arranged on the upper surface of the impeller 201 and is not fixed to the impeller 201. The rotation of the impeller 201 cannot drive the control console 302 to rotate. When the movable rod 3011 expands outward under the influence of centrifugal force, when the convex surface 3012 on the surface contacts the concave surface 3021 on the inner wall of the control console 302, the control console 302 is driven by the movable rod 3011 to rotate on the upper surface of the impeller 201.

[0047] Refer to Figure 8 , Figure 10 , a moving sleeve 304 is provided at the end of the control console 302. The end of the moving sleeve 304 extends into a fixed sleeve 305 provided on the inner wall of the chamber 103. A first joint 3022 is provided at the end of the control console 302, and the end of the first joint 3022 extends into the inner wall of the moving sleeve 304. A third elastic member 3024 is provided at the end of the first joint 3022. The third elastic member 3024 is used to separate the first joint 3022 and a second joint 3041 provided on the inner wall of the moving sleeve 304.

[0048] Among them, a first joint 3022 is provided on the upper surface of the control console 302, and the first joint 3022 extends into the interior of the moving sleeve 304. When the second joint 3041 provided on the bottom surface of the inner wall of the moving sleeve 304 is clamped with the first joint 3022, the entire moving sleeve 304 is driven to rotate on the upper surface of the impeller 201 under the influence of the first joint 3022. A third elastic member 3024 provided on the lower surface of the first joint 3022 is used to separate the first joint 3022 and the second joint 3041.

[0049] A moving member is provided at the end of the first joint 3022. The moving member includes a disc 303 sleeved on the outer wall of the transmission shaft 202. A reduction gear set 3032 is provided at the end of the disc 303, and the reduction gear set 3032 meshes with a driving gear 3023 provided at the end of the first joint 3022. The reduction gear set 3032 drives the disc 303 to rotate on the inner wall of the moving sleeve 304. A convex block 3031 provided on the outer wall of the disc 303 extends into a movement groove 3042 provided on the inner wall of the moving sleeve 304, so that the disc 303 moves downward on the inner wall of the moving sleeve 304 and at the same time the first joint 3022 is clamped with the second joint 3041.

[0050] Among them, the reduction gear set 3032 is located below the disc 303. The bottommost part of the reduction gear set 3032 meshes with the driving gear 3023 on the surface of the first joint 3022. When the first joint 3022 rotates, the gear at the bottommost part of the reduction gear set 3032 is driven to rotate by the driving gear 3023. Through step-by-step transmission to the uppermost gear, the disc 303 is driven to rotate. The rotation speed of the disc 303 is much lower than the rotation speed of the driving gear 3023. At the same time, when the disc 303 rotates, the bumps 3031 on its surface slide inside the movement grooves 3042 on the surface of the movement sleeve 304. Since the movement sleeve 304 is fixed inside the fixed sleeve 305, at this time, when the disc 303 rotates, it moves downward until the first joint 3022 engages with the second joint 3041. At this time, the impeller 201 moves downward on the surface of the transmission shaft 202 until the first joint 3022 engages with the second joint 3041 and drives the second joint 3041 to rotate, that is, the movement sleeve 304 rotates with the impeller 201.

[0051] When the sewage viscosity in the chamber 103 is low and the particulate content is small, at this time, the rotation speed of the impeller 201 is relatively fast and it is located at a lower position inside the chamber 103. The impeller 201 is close to the water inlet 1021 below the pump body 102. The fluid can enter the impeller 201 more smoothly and the impeller 201 can drive the fluid more fully when rotating, which can increase the flow rate of the pump.

[0052] Preferably, referring to Figures 8 to 10 , the inner wall of the fixed sleeve 305 is provided with a plurality of fourth elastic members 3051 arranged in an array, and the end of the fourth elastic member 3051 is provided with a ball 3052. The fourth elastic member 3051 is used to push the ball 3052 to engage it into the circular groove 3043 opened at the end of the movement sleeve 304. Through the cooperation of the ball 3052 and the circular groove 3043, the movement sleeve 304 is fixed inside the fixed sleeve 305.

[0053] Among them, a plurality of fourth elastic members 3051 are arranged in an array inside the fixed sleeve 305 and push the ball 3052 to engage it into the circular groove 3043 opened on the surface of the movement sleeve 304. Before the first joint 3022 moves downward to engage with the second joint 3041, the movement sleeve 304 is fixed inside the fixed sleeve 305 and does not move.

[0054] In summary, when in use, when the impeller 201 stops, at this time, the transmission shaft 202 does not rotate, the third elastic member 3024 is not squeezed, the first joint 3022 and the second joint 3041 are separated, and at this time, the impeller 201 is located at a higher position inside the chamber 103.

[0055] When the drive motor 101 starts, when the viscosity of the medium flowing inside the chamber 103 is low and the solid particles are few, the flow of the medium at this time will not interfere with the rotation speed of the impeller 201. At this time, the rotation speed of the impeller 201 is relatively fast. When the impeller 201 rotates, the connecting plate 301 on the surface rotates with the impeller 201, and at the same time, the movable rod 3011 expands outwards under the action of centrifugal force. The convex surface 3012 on the surface of the movable rod 3011 contacts the concave surface 3021 on the surface of the control console 302, so that the control console 302 rotates synchronously with the impeller 201. When the control console 302 rotates, the first joint 3022 at the axis of the control console 302 and the drive gear 3023 on the surface of the first joint 3022 rotate together. The reduction gear set 3032 moves driven by the drive gear 3023, transmits the rotation of the drive gear 3023 to the disc 303, so that the disc 303 rotates slowly inside the moving sleeve 304. While the convex block 3031 on the surface slides inside the moving groove 3042, the disc 303 drives the first joint 3022 below to move downwards and finally engage with the second joint 3041 at the bottom, driving the moving sleeve 304 to rotate. When the moving sleeve 304 rotates, the moving groove 3042 at the top presses the ball 3052, causing it to press the fourth elastic member 3051 and retract inwards, so that the moving sleeve 304 can rotate inside the fixed sleeve 305. At this time, the impeller 201 is at a lower position on the surface of the transmission shaft 202, and the fluid can enter the impeller 201 more smoothly. When the impeller 201 rotates, it can drive the fluid more fully, increasing the flow rate of the pump body 102.

[0056] When the medium entering the pump body 102 contains more solid particles and the viscosity of the medium is relatively large, at this time, the rotation speed of the impeller 201 is affected by the medium and is relatively slow. At this time, the centrifugal force generated by the rotation of the impeller 201 is small, and the centrifugal force received by the movable rod 3011 on the surface of the connecting plate 301 is not enough to overcome the tension of the second elastic member 3014. The rotation of the impeller 201 cannot drive the control console 302 to rotate. At this time, the disc 303 inside the moving sleeve 304 does not rotate, the first joint 3022 does not move downwards, and the impeller 201 rotates at a higher position inside the pump body 102 at this time, improving the flow state of the fluid inside the pump body 102, reducing the friction and collision between the fluid and the pump body 102 and the impeller 201, reducing the possibility of blockage and wear, and improving the conveying efficiency and stability of the pump.

[0057] Embodiment 3

[0058] This is the third embodiment of this application, and this embodiment is implemented based on the previous embodiment.

[0059] Specifically, refer to Figures 2 to 7, the cutting component includes a fixed ring 204 fixed to the end of the chamber 103. Fixed blades 2041 are arranged in an array on the inner wall of the fixed ring 204. A bearing 2042 is arranged at the axis of the fixed ring 204, and the bearing 2042 is sleeved on the outer wall of the transmission shaft 202. An active ring 205 is arranged at the end of the fixed ring 204, and a second bevel gear 2022 is arranged at the axis of the active ring 205. The second bevel gear 2022 is sleeved on the outer wall of the transmission shaft 202 to drive the active ring 205 to rotate.

[0060] Among them, the fixed ring 204 is fixed to the bottom of the chamber 103. At the water inlet 1021 below the pump body 102, a plurality of fixed blades 2041 are arranged in an array inside the fixed ring 204. A bearing 2042 is installed at the axis, and the bearing 2042 is sleeved on the outside of the bottom of the transmission shaft 202, which not only does not affect the rotation of the transmission shaft 202 but also plays a role in fixing the transmission shaft 202.

[0061] Preferably, referring to Figures 4 to 7 , a first bevel gear 2021 is also sleeved on the outer wall of the transmission shaft 202. An installation frame 203 is arranged on the outer wall of the transmission shaft 202, and the installation frame 203 is fixed to the inner wall of the chamber 103. A third bevel gear 2031 is arranged on the inner wall of the installation frame 203 for transmission. The rotation direction of the second bevel gear 2022 is opposite to that of the first bevel gear 2021.

[0062] Among them, as Figure 6 shown, the first bevel gear 2021 is sleeved on the outside of the transmission shaft 202 and rotates synchronously with the transmission shaft 202. The second bevel gear 2022 is located below the first bevel gear 2021 and is outside the rotating cylinder sleeved on the outside of the transmission shaft 202, and is not affected by the rotation of the transmission shaft 202. The third bevel gear 2031 meshes with the first bevel gear 2021 and the second bevel gear 2022 at the same time, and can transmit the rotation of the first bevel gear 2021 to the second bevel gear 2022. The rotation direction of the second bevel gear 2022 is opposite to that of the first bevel gear 2021.

[0063] Moving rods 2052 are arranged in an array on the inner wall of the active ring 205, and the ends of the moving rods 2052 extend into the inner groove 2051 opened on the inner wall of the active ring 205. A limiting plate 2053 is arranged on the outer wall of the moving rod 2052. The limiting plate 2053 cooperates with the inner groove 2051 to prevent the moving rod 2052 from rotating. A first elastic member 2055 is also arranged at the end of the moving rod 2052 to push the moving rod 2052.

[0064] Among them, the axis of the movable ring 205 is fixed on the rotating cylinder below the second bevel gear 2022. The movable ring 205 rotates with the second bevel gear 2022. The rotation direction of the movable ring 205 is opposite to that of the impeller 201. By the interaction between the reverse rotation of the movable ring 205 and the impeller 201, part of the eddy current can be offset, making the fluid flow more orderly and reducing the flow resistance.

[0065] Both ends of the moving rod 2052 are respectively provided with first elastic members 2055. The moving rod 2052 is limited by the first elastic members 2055 at both ends. When the moving rod 2052 moves, when the external force is lost, the first elastic members 2055 are used to reset the moving rod 2052.

[0066] At the same time, the limiting plate 2053 at the end of the moving rod 2052 cooperates with the inner groove 2051 on the inner wall of the movable ring 205 to limit the moving rod 2052 to prevent it from rotating and only allowing linear movement.

[0067] Preferably, a cutting blade 2056 is further arranged inside the movable ring 205. An activity channel 2057 is opened inside the cutting blade 2056. The moving rod 2052 is located in the activity channel 2057. The sliding column 2054 on the outer wall of the moving rod 2052 cooperates with the inclined groove 2058 opened on the inner wall of the activity channel 2057 to drive the cutting blade 2056 to flip.

[0068] Among them, the cutting blade 2056 is sleeved outside the moving rod 2052. The internal activity channel 2057 allows the moving rod 2052 to slide. At the same time, the sliding column 2054 on the surface of the moving rod 2052 cooperates with the inclined groove 2058 on the inner wall of the activity channel 2057. In the initial state, the cutting blade 2056 does not move and rotates above the fixed ring 204 with the movable ring 205, and cooperates with the fixed blade 2041 to cut the particles in the medium. When encountering particles that cannot be cut, the cutting blade 2056 flips inside the movable ring 205 to expand the gap between adjacent cutting blades 2056 for the particles to pass through, avoiding damage to the cutting blade 2056 and affecting subsequent use. When the cutting blade 2056 flips, the internal moving rod 2052 moves in the activity channel 2057 and squeezes the first elastic member 2055 due to the cooperation between the sliding column 2054 and the inclined groove 2058. After the solid particles pass through, the first elastic member 2055 pushes the moving rod 2052 to reset, and the cutting blade 2056 also resets and continues to cooperate with the fixed blade 2041 for cutting work.

[0069] In summary, during use, the fixed blade 2041 array is within the fixed ring 204, installed above the water inlet 1021, and cooperates with the cutting blade 2056 to cut and crush the solid particles entering the chamber 103, avoiding blockage inside the pump body 102 subsequently. The movable ring 205 is connected to the second bevel gear 2022 and rotates in the opposite direction to the impeller 201 to counteract the generated eddy current. Meanwhile, during the cutting operation, when encountering solid particles with a relatively large volume, the cutting blade 2056 will flip to increase the gap between adjacent cutting blades 2056 for the particles to pass through, and then flip back to its original position to continue the cutting and crushing work with the fixed blade 2041.
