Description

Technical Field

[0001] The present application relates to the technical field of sewage pumps, and in particular to a non-clogging sewage pump. Background Art

[0002] The impeller design of traditional sewage pumps is relatively conventional. When faced with sewage containing a large amount of solid particles, such as construction waste, industrial waste slag, and daily garbage fragments, the solids can easily get stuck in the gap between the impeller and the pump body, causing the impeller to get stuck and the pump to fail to operate normally. For substances containing long fibers, such as fiber bundles in textile wastewater and papermaking wastewater, they can easily get entangled on the impeller, and become tighter and tighter over time, which not only reduces the pump's delivery efficiency, but also destroys the dynamic balance of the impeller, causing the pump body to vibrate and shortening the service life of the equipment.

[0003] The patent application with publication number CN118462598A discloses a non-clogging and non-sealed self-priming sewage pump, including a pump body, a motor installed on the top of the pump body, and a shaft structure installed at the output end of the motor and extending to the inside of the pump body. A water inlet assembly for filtering solid particles is installed on one side of the pump body, and an impeller assembly is fixedly sleeved on the outer surface of the shaft structure. A plurality of positioning interception assemblies are installed on the inner wall of the pump body to cooperate with the impeller assembly to shear the windings entering the pump body. The positioning interception assembly includes a reinforcement strip installed on the inner wall of the pump body and arranged in an inclined manner, and interception strips that are wide at the top and narrow at the bottom and arranged in an upper and lower dislocation are installed at both ends of the reinforcement strip. This technical solution can perform a detailed segmentation operation on the fibrous windings entering the pump body, thereby reducing the length of the windings, thereby reducing the subsequent damage to the impeller, and can filter the middle and lower layers of the sewage flow, and avoid complete blockage of the pipeline on the basis of effectively intercepting most hardened substances.

When the viscosity of the sewage inside the chamber is low and the content of particulate matter is small, the impeller rotates faster and is located at a lower position inside the chamber, close to the water inlet, so that the fluid can enter the impeller more smoothly. When the impeller rotates, it drives the fluid more fully, increasing the flow rate of the pump. At the same time, the cutting component is located inside the chamber, and the fixed blade in the fixed ring cooperates with the cutting blade on the movable ring to cut and crush the solid particles entering the chamber, effectively avoiding blockage inside the pump body.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the drawings in the specification.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present application. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Example 1

[0024] This is the first embodiment of the present application, which provides a non-clogging sewage pump.

[0025] Specifically, refer to Figure 1~Figure 4 The main assembly 100 includes a driving motor 101, a pump body 102 disposed at the end of the driving motor 101, and a chamber 103 disposed on the inner wall of the pump body 102; The motion component 200 arranged inside the chamber 103 includes an impeller 201 and a transmission shaft 202 arranged at the axis of the impeller 201. A cutting component is arranged at the end of the transmission shaft 202, and the cutting component is used to cut solid particles to prevent clogging. At the same time, an adjusting component is arranged at the end of the impeller 201. The adjusting component 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, and is used to increase the space for fluid flow when blockage occurs in the chamber 103 or sewage with high viscosity medium is discharged.

[0026] Among them, the cutting component is located inside the chamber 103. When the driving motor 101 is started, the 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 connected to the top of the chamber 103. At this time, the sewage will pass through the cutting component and then enter the interior of the chamber 103. The solid particles in the sewage are cut by the cutting component to avoid blockage. At the same time, when the cutting component encounters particles that cannot be cut, it will undergo adaptive changes to allow the particles to pass through, thereby avoiding damage to the blade.

[0027] The connector 1011 provided on the drive motor 101 and the transmission shaft 202 adopt an electromagnetic coupling method to prevent the drive motor 101 from being damaged 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 high or the particulate content is large, the rotation speed of the impeller 201 is affected. At this time, the adjusting component causes the impeller 201 to move upward inside the chamber 103, increasing the space for the medium to circulate 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, and reduce blockage and wear.

[0028] Example 2

[0029] This is the second embodiment of the present application, and this embodiment is implemented based on the previous embodiment.

[0030] Specifically, refer to Figure 8~Figure 10 The adjusting component includes a connecting plate 301, which is fixed to the end of the impeller 201 and sleeved on the outer wall of the transmission shaft 202. The end face array of the connecting plate 301 is provided with a movable rod 3011, 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, and 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 make it move inward.

[0031] 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. When the speed of the connecting plate 301 is low, they move closer to the direction of the transmission shaft 202. When the speed of the impeller 201 is high, under the action of centrifugal force, the movable rods 3011 overcome the pulling force of the second elastic member 3014 and open outward.

[0032] Preferably, refer to Figure 8 , Fig. 9The outer wall of the connecting plate 301 is provided with a control console 302 and the inner wall of the control console 302 is provided with a concave surface 3021, the concave surface 3021 cooperates with the 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.

[0033] Among them, the control console 302 is set 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 opens outward due to the influence of centrifugal force, the convex surface 3012 on the surface contacts the concave surface 3021 of the inner wall of the control console 302, and the control console 302 is driven to rotate on the upper surface of the impeller 201 through the movable rod 3011.

[0034] Reference Figure 8 , Fig.10 A moving sleeve 304 is provided at the end of the console 302, and 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 console 302, and the end of the first joint 3022 extends to the inner wall of the moving sleeve 304. A third elastic member 3024 is provided at the end of the first joint 3022, and 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.

[0035] Among them, a first joint 3022 is provided on the upper surface of the console 302, and the first joint 3022 extends to the interior of the moving sleeve 304. When the second joint 3041 set on the bottom surface of the inner wall of the moving sleeve 304 is engaged with the first joint 3022, the entire moving sleeve 304 will be driven to rotate on the upper surface of the impeller 201 under the influence of the first joint 3022. The third elastic member 3024 set on the lower surface of the first joint 3022 is used to separate the first joint 3022 and the second joint 3041.

[0036] A moving component is provided at the end of the first joint 3022, and the moving component 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 is meshed with the 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. The protrusion 3031 provided on the outer wall of the disc 303 extends into the moving groove 3042 opened 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 and the second joint 3041 are clamped.

[0037] The reduction gear set 3032 is located below the disk 303, and the bottom of the reduction gear set 3032 is meshed with the driving gear 3023 on the surface of the first joint 3022. When the first joint 3022 rotates, the driving gear 3023 drives the gear at the bottom of the reduction gear set 3032 to rotate, and then drives the disk 303 to rotate step by step. The rotation speed of the disk 303 is much lower than the rotation speed of the driving gear 3023. At the same time, when the disk 303 rotates, the surface The protrusion 3031 slides inside the moving groove 3042 on the surface of the moving sleeve 304. Since the moving sleeve 304 is fixed inside the fixed sleeve 305, the disc 303 moves downward when rotating until the first joint 3022 is engaged 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 is engaged with the second joint 3041 and drives the second joint 3041 to rotate, that is, the moving sleeve 304 rotates with the impeller 201.

[0038] When the viscosity of sewage in the chamber 103 is low and the particulate matter content is small, the impeller 201 rotates faster and 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, thereby increasing the flow rate of the pump.

[0039] Better, refer to Figure 8~Figure 10 A fourth elastic member 3051 is arranged in an array on the inner wall of the fixed sleeve 305 and a round ball 3052 is arranged at the end of the fourth elastic member 3051. The fourth elastic member 3051 is used to push the round ball 3052 so that it is engaged into the circular groove 3043 opened at the end of the moving sleeve 304. The moving sleeve 304 is fixed in the fixed sleeve 305 through the cooperation between the round ball 3052 and the circular groove 3043.

[0040] Among them, the fourth elastic member 3051 is provided with a plurality of arrays inside the fixed sleeve 305 and pushes the round ball 3052 to engage into the round groove 3043 opened on the surface of the moving sleeve 304. Before the first joint 3022 moves downward and engages with the second joint 3041, the moving sleeve 304 is fixed inside the fixed sleeve 305 and does not move.

[0041] In summary, during use, when the impeller 201 is stopped, the transmission shaft 202 does not rotate, the third elastic member 3024 is not squeezed, and the first joint 3022 and the second joint 3041 are separated. At this time, the impeller 201 is located at a higher position in the chamber 103.

[0042] When the driving motor 101 is started, when the viscosity of the medium flowing inside the chamber 103 is low and the solid particles are small, the circulation of the medium 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. At the same time, the movable rod 3011 opens outward under the action of centrifugal force, and 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 and the impeller 201 rotate synchronously. When the control console 302 rotates, the first joint 3022 at the axis of the control console 302 and the driving gear 3023 on the surface of the first joint 3022 rotate together, and the reduction gear set 3032 is driven by the driving gear 3023 to move, The rotation of 3023 is transmitted to the disc 303, so that the disc 303 rotates slowly inside the moving sleeve 304. While the protrusion 3031 on the surface slides inside the moving groove 3042, the disc 303 drives the first joint 3022 below to move downward 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 squeezes the ball 3052, causing it to squeeze the fourth elastic member 3051 and retreat inward, 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, thereby increasing the flow rate of the pump body 102.

[0043] When the medium entering the pump body 102 contains more solid particles and has a higher viscosity, the rotation speed of the impeller 201 is affected by the medium more slowly. At this time, the centrifugal force of the impeller 201 is small, and the centrifugal force exerted on the movable rod 3011 on the surface of the connecting plate 301 is not enough to overcome the pulling force 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, and the first joint 3022 does not move downward. The impeller 201 is located at a higher position inside the pump body 102 and rotates, thereby improving the flow state of the fluid in 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 delivery efficiency and stability of the pump.

[0044] Example 3

[0045] This is the third embodiment of the present application, and this embodiment is implemented based on the previous embodiment.

[0046] Specifically, refer to Figure 2~Figure 7The cutting component includes a fixed ring 204 fixed to the end of the chamber 103, a fixed blade 2041 is 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, a movable 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 movable ring 205, and the second bevel gear 2022 is sleeved on the outer wall of the transmission shaft 202 to drive the movable ring 205 to rotate.

[0047] Among them, the fixing ring 204 is fixed at the bottom of the chamber 103. At the water inlet 1021 below the pump body 102, the internal array of the fixing ring 204 has multiple fixed blades 2041, and a bearing 2042 is installed at the axis. The bearing 2042 is sleeved on the outer side of the bottom of the transmission shaft 202, which does not affect the rotation of the transmission shaft 202 and also fixes the transmission shaft 202.

[0048] Preferably, refer to Figure 4~Figure 7 The outer wall of the transmission shaft 202 is also sleeved with a first bevel gear 2021, the outer wall of the transmission shaft 202 is provided with a mounting frame 203 and the mounting frame 203 is fixed to the inner wall of the chamber 103, the inner wall of the mounting frame 203 is provided with a third bevel gear 2031 and the third bevel gear 2031 is used for transmission, and the rotation direction of the second bevel gear 2022 is opposite to that of the first bevel gear 2021.

[0049] Among them, Figure 6 As 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 sleeved on the outside of the rotating cylinder outside the transmission shaft 202. It is not affected by the rotation of the transmission shaft 202. The third bevel gear 2031 is meshed with the first bevel gear 2021 and the second bevel gear 2022 at the same time, and the rotation of the first bevel gear 2021 can be transmitted 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.

[0050] The inner wall array of the movable ring 205 is provided with a moving rod 2052, and the end of the moving rod 2052 extends into the inner groove 2051 opened on the inner wall of the movable ring 205. The outer wall of the moving rod 2052 is provided with a limiting plate 2053. The limiting plate 2053 cooperates with the inner groove 2051 to prevent the moving rod 2052 from rotating. The end of the moving rod 2052 is also provided with a first elastic member 2055 for pushing the moving rod 2052.

[0051] Among them, the axis center of the movable ring 205 is fixed on the rotating drum 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 the rotation direction of the impeller 201. Through the reverse rotation of the movable ring 205 and the interaction with the impeller 201, part of the vortex can be offset, making the fluid flow more orderly and reducing the flow resistance.

[0052] The two ends of the moving rod 2052 are respectively provided with first elastic members 2055 , and the moving rod 2052 is limited by the first elastic members 2055 at both ends. When the moving rod 2052 moves, when there is no external force, the moving rod 2052 is reset by the first elastic member 2055 .

[0053] At the same time, the limiting plate 2053 at the end of the moving rod 2052 cooperates with the inner groove 2051 of the inner wall of the movable ring 205 to limit the moving rod 2052 to prevent it from rotating and only allow it to move in a straight line.

[0054] Preferably, a cutting blade 2056 is also provided inside the movable ring 205, a movable channel 2057 is opened inside the cutting blade 2056, the movable rod 2052 is located in the movable channel 2057, and the sliding column 2054 on the outer wall of the movable rod 2052 cooperates with the inclined groove 2058 opened on the inner wall of the movable channel 2057 to drive the cutting blade 2056 to flip.

[0055] The cutting blade 2056 is sleeved on the outside of the moving rod 2052, and the internal movable channel 2057 is used for 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 movable channel 2057. In the initial state, the cutting blade 2056 does not move, and rotates with the movable ring 205 above the fixed ring 204, 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 moves inside the movable ring 205. Flipping, expanding the gap between the adjacent cutting blade 2056 to allow 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 movable 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 to continue to cooperate with the fixed blade 2041 to perform cutting work.

[0056] In summary, when in use, the fixed blade 2041 is arrayed in 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 to avoid subsequent blockage inside the pump body 102. The movable ring 205 is connected to the second bevel gear 2022, which is opposite to the rotation direction of the impeller 201, and is used to offset the generated eddy current. At the same time, when performing the cutting work, when encountering larger solid particles, the cutting blade 2056 will flip over, increasing the gap between the adjacent cutting blade 2056 for the particles to pass through, and then flip over and reset again to continue cutting and crushing with the fixed blade 2041.
