Description

Technical Field

[0001] The present application relates to the field of water pipes, and in particular to a suction pump head with a crushing function. Background Art

[0002] At present, during the repair of urban underground pipelines, sewage trucks are needed to pump out sewage from pipelines or pumping stations.

[0003] In the related art, when it is necessary to pump out the sewage in an underground pipeline or a pumping station, a pumping pipe is usually directly extended into the sewage, and the sewage in the underground pipeline or the pumping station is directly pumped out by a pump.

[0004] The above-mentioned related technologies have the following defects: sewage is often mixed with a lot of solid waste, such as plastic bags, etc. If impurities such as plastic bags are pumped into the pipeline, it is easy to cause pipeline congestion and even cause equipment damage, affecting the construction progress. Utility Model Content

[0005] In order to prevent the water pump from getting blocked when pumping sewage, the present application provides a suction pump head with a breaking function.

[0006] The present application provides a suction pump head with a crushing function, which adopts the following technical solution:

[0007] A suction pump head with a crushing function, comprising a water inlet pipe and a crushing assembly, wherein the crushing assembly comprises a rotating shaft and a plurality of arc-shaped blades, wherein the rotating shaft is coaxially and rotatably mounted in the water inlet pipe;

[0008] The arc-shaped blade is arranged between the rotating shaft and the water inlet pipe, and is radially mounted on the side wall of the rotating shaft and is also perpendicular to the axis of the rotating shaft;

[0009] In the longitudinal direction of the rotating shaft, the plurality of arc-shaped blades are distributed at intervals, and in the circumferential direction of the rotating shaft, the plurality of arc-shaped blades are distributed in staggered positions.

[0010] By adopting the above technical solution, the arc-shaped blade is driven to rotate by the rotating shaft. When impurities such as plastic bags in the water flow pass through the water inlet pipe, the arc-shaped blade can effectively crush them. At the same time, the staggered distribution in the length direction and circumference of the rotating shaft can increase the frequency of contact between the blade and solid particles, further improving the crushing effect, and thus making it less likely for the water pump to be blocked when pumping sewage.

[0011] Optionally, the water inlet pipe includes a first flared pipe, a straight pipe, a second flared pipe, and a connecting pipe, wherein the first flared pipe, the straight pipe, the second flared pipe, and the connecting pipe are coaxially connected in sequence, and an end of the first flared pipe with a smaller diameter is connected to the straight pipe, and an end of the second flared pipe with a larger diameter is connected to the straight pipe;

[0012] The rotating shaft is coaxially and rotatably installed in the straight tube.

[0013] By adopting this technical solution, impurities and water begin a pre-crushing phase at the first bell tube. After entering the straight tube, the crushing assembly thoroughly crushes large debris. The crushed small impurities and water then flow rapidly through the second bell tube, which also guides the water flow. Furthermore, because the crushing assembly occupies space within the water inlet pipe, the larger diameter end of the second bell tube is connected to the straight tube. This ensures that the inner diameter of the straight tube, where the crushing assembly is located, is larger than the inner diameter of the connecting pipe for the water outlet, facilitating smooth water pumping through the water inlet pipe.

[0014] Optionally, a first acceleration assembly is provided in the straight pipe, the first acceleration assembly comprising a first circular ring and a plurality of first water supply blades, and the first circular ring is coaxially and rotatably mounted in the straight pipe;

[0015] The rotating shaft is arranged on the inner side of the first circular ring, and the first water supply blade is arranged obliquely between the rotating shaft and the first circular ring, with one end connected to the rotating shaft and the other end connected to the first circular ring;

[0016] The plurality of first water supply blades are distributed at intervals along the circumference of the rotating shaft.

[0017] By adopting the above technical solution, the first ring drives the multiple first water supply blades to rotate, thereby increasing the driving force of the water flow and thereby improving the efficiency of the crushing. In addition, the first water supply blades can also drive the rotating shaft to rotate.

[0018] Optionally, a coaxial first annular groove is provided on the inner wall of the straight tube, and the first ring is coaxially and rotatably disposed in the first annular groove and is dynamically sealed to the straight tube;

[0019] The inner diameter of the first circular ring is equal to the inner diameter of the straight tube.

[0020] By adopting the above technical solution, the first ring is embedded in the inner wall of the straight tube, so that the first ring will not intercept impurities.

[0021] Optionally, both ends of the first circular ring are connected to the straight tube with a coaxial first sealed bearing;

[0022] The first sealed bearing is located in the first annular groove, and has an inner diameter equal to that of the straight pipe.

[0023] By adopting the above technical solution, the first ring is rotatably connected to the straight tube through the first sealing bearing and the dynamic sealing connection, so that impurities are not easy to enter between the first ring and the straight tube when the first ring rotates.

[0024] Optionally, a driving assembly is provided on the outer side wall of the straight tube, and the driving assembly includes a waterproof cover, a motor, a driving gear and a driven gear;

[0025] The motor is installed in the waterproof cover;

[0026] The driving gear is connected to the motor;

[0027] The driven gear is coaxially mounted on the outer side wall of the first ring;

[0028] A connecting through hole is provided at the bottom of the first annular groove, and the driving gear is meshed with the driven gear after passing through the connecting through hole;

[0029] The waterproof cover on the side of the connecting through hole is sealedly connected to the straight pipe.

[0030] By adopting the above technical solution, the motor drives the driving gear to rotate, the driving gear drives the driven gear, and then the driven gear drives the first ring, thereby driving the first water supply blade and the arc-shaped blade to rotate.

[0031] Optionally, a second accelerating assembly is further provided in the straight tube, and the second accelerating assembly is provided at an end of the rotating shaft away from the first accelerating assembly;

[0032] The second accelerating assembly includes a second circular ring and a plurality of second water supply blades, wherein the second circular ring is coaxially and rotatably mounted in the straight pipe;

[0033] The rotating shaft is arranged on the inner side of the second circular ring, and the second water supply blade is arranged obliquely between the rotating shaft and the second circular ring, with one end connected to the rotating shaft and the other end connected to the second circular ring;

[0034] The plurality of second water supply blades are distributed at intervals along the circumference of the rotating shaft.

[0035] By adopting the above technical solution, the second acceleration component is rotated by the rotating shaft, and the second water supply blade increases the driving force of the water flow, thereby improving the crushing efficiency. In addition, in conjunction with the first acceleration component, it can support both ends of the rotating shaft, thereby improving the stability of the rotating shaft.

[0036] Optionally, a coaxial second annular groove is provided on the inner wall of the straight tube, and the second ring is coaxially and rotatably disposed in the second annular groove and is dynamically sealed to the straight tube;

[0037] The inner diameter of the second circular ring is equal to the inner diameter of the straight tube.

[0038] By adopting the above technical solution, the second ring is embedded in the inner wall of the straight tube, so that the second ring will not intercept impurities.

[0039] Optionally, both ends of the second ring are connected to the straight tube with coaxial second sealed bearings;

[0040] The second sealed bearing is located in the second annular groove, and has an inner diameter equal to that of the straight pipe.

[0041] By adopting the above technical solution, the second ring is rotatably connected to the straight tube through the second sealing bearing and the dynamic sealing connection, so that impurities are not easy to enter between the second ring and the straight tube when the second ring rotates.

[0042] In summary, this application includes at least one of the following beneficial technical effects:

[0043] 1. In this application, the arc-shaped blades are driven to rotate by the rotating shaft. When impurities such as plastic bags in the water flow pass through the water inlet pipe, the arc-shaped blades can effectively crush them. At the same time, the staggered distribution in the length direction and circumference of the rotating shaft can increase the frequency of contact between the blades and solid particles, further improving the crushing effect, thereby making it less likely for the water pump to be blocked when sucking sewage.

[0044] 2. In this application, since the setting of the crushing component occupies the space in the water inlet pipe, the end with the larger diameter of the second trumpet is connected to the straight pipe, so that the inner diameter of the straight pipe used to set the crushing component is larger than the inner diameter of the connecting pipe used for water outlet, which is conducive to the water pump to pump water smoothly through the water inlet pipe.

[0045] 3. The second acceleration component in the present application drives the plurality of first water supply blades to rotate through the first ring, thereby increasing the driving force of the water flow and thereby improving the efficiency of the crushing, and the first water supply blades can also drive the rotating shaft to rotate.

[0054] The following is combined with Figure 1-4 This application is described in further detail.

[0055] The embodiment of the present application discloses a suction pump head with a crushing function. Figure 1 and Figure 2 A suction pump head with a crushing function includes a water inlet pipe 1, a first acceleration component 2, a second acceleration component 3, a crushing component 4 and a drive component 5. The crushing component 4 includes a rotating shaft 41 and a plurality of arc-shaped blades 42. The rotating shaft 41 is coaxially and rotatably installed in the water inlet pipe 1. The arc-shaped blades 42 are arranged between the rotating shaft 41 and the water inlet pipe 1, and are radially installed on the side wall of the rotating shaft 41, and are also perpendicular to the axis of the rotating shaft 41. In the longitudinal direction of the rotating shaft 41, the plurality of arc-shaped blades 42 are distributed at intervals, and in the circumferential direction of the rotating shaft 41, the plurality of arc-shaped blades 42 are staggered. The first acceleration component 2 and the second acceleration component 3 are respectively connected to the two ends of the rotating shaft 41, and can be rotatably installed in the water inlet pipe 1. The drive component 5 is installed on the outer wall of the water inlet pipe 1, and is used to drive the first acceleration component 2 to rotate.

[0056] Reference Figure 1 and Figure 2In the embodiment of the present application, the drive assembly 5 drives the first acceleration assembly 2 to rotate, thereby driving the second acceleration assembly 3 and the crushing assembly 4 to rotate. The arc-shaped blade 42 is driven to rotate by the rotating shaft 41. When impurities such as plastic bags in the water flow pass through the water inlet pipe 1, the arc-shaped blade 42 can effectively crush them. At the same time, the staggered distribution in the longitudinal and circumferential directions of the rotating shaft 41 can increase the frequency of contact between the blade and solid particles, further improving the crushing effect. The first acceleration assembly 2 and the second acceleration assembly 3 are used to increase the flow rate of the water flow and increase the driving force of the water flow, thereby improving the crushing efficiency of the crushing assembly 4. This makes it less likely that the water pump will become blocked when pumping sewage.

[0057] Reference Figure 1 and Figure 2 The water inlet pipe 1 includes a first flared pipe 11, a straight pipe 12, a second flared pipe 13, and a connecting pipe 14. The first flared pipe 11, the straight pipe 12, the second flared pipe 13, and the connecting pipe 14 are coaxially connected in sequence. The smaller diameter end of the first flared pipe 11 is connected to the straight pipe 12, and the larger diameter end of the second flared pipe 13 is connected to the straight pipe 12. A rotating shaft 41 is coaxially rotatably mounted within the straight pipe 12. Multiple side water inlet holes 1101 are provided on the wall of the first flared pipe 11.

[0058] Reference Figure 1 and Figure 2 In this embodiment, impurities and water begin a pre-crushing phase at the first bell tube 11 before entering the straight tube 12. The crushing assembly 4 thoroughly crushes large impurities, and the crushed small impurities and water quickly flow through the second bell tube 13, which also guides the water flow. Furthermore, because the crushing assembly 4 occupies space within the water inlet pipe 1, the larger diameter end of the second bell tube 13 is connected to the straight tube 12. This makes the inner diameter of the straight tube 12, where the crushing assembly 4 is located, larger than the inner diameter of the connecting pipe 14 for the water outlet, facilitating the pump's ability to pump water through the water inlet pipe 1.

[0059] Reference Figure 2 and Figure 3 A first acceleration assembly 2 is provided in the straight tube 12. The first acceleration assembly 2 includes a first circular ring 21 and a plurality of first water supply blades 23. The first circular ring 21 is coaxially and rotatably mounted in the straight tube 12. The rotating shaft 41 is provided on the inner side of the first circular ring 21. The first water supply blades 23 are obliquely provided between the rotating shaft 41 and the first circular ring 21, with one end connected to the rotating shaft 41 and the other end connected to the first circular ring 21. The plurality of first water supply blades 23 are circumferentially spaced along the rotating shaft 41. The first circular ring 21 drives the plurality of first water supply blades 23 to rotate, thereby increasing the driving force of the water flow and thereby improving the efficiency of the crushing. In addition, the first water supply blades 23 can also drive the rotating shaft 41 to rotate.

[0060] Reference Figure 2 and Figure 3The inner wall of the straight tube 12 is provided with a coaxial first annular groove 1201. The first ring 21 is coaxially and rotatably disposed within the first annular groove 1201 and is dynamically sealed to the straight tube 12. The inner diameter of the first ring 21 is equal to that of the straight tube 12. The first ring 21 is embedded in the inner wall of the straight tube 12, preventing it from intercepting impurities.

[0061] Reference Figure 2 and Figure 3 First sealed bearings 22 are coaxially connected between the first annular ring 21 and the straight tube 12 at both ends. The first sealed bearings 22 are located within the first annular groove 1201 and have an inner diameter equal to that of the straight tube 12. The first annular ring 21 is rotatably connected to the straight tube 12 via the first sealed bearings 22, creating a dynamic seal. This prevents impurities from entering the space between the first annular ring 21 and the straight tube 12 during rotation.

[0062] Reference Figure 2 and Figure 4 A second acceleration component 3 is also provided in the straight tube 12. The second acceleration component 3 is provided at one end of the rotating shaft 41 away from the first acceleration component 2. The second acceleration component 3 includes a second circular ring 31 and a plurality of second water supply blades 33. The second circular ring 31 is coaxially and rotatably mounted in the straight tube 12. The rotating shaft 41 is provided on the inner side of the second circular ring 31. The second water supply blades 33 are tilted between the rotating shaft 41 and the second circular ring 31, and one end is connected to the rotating shaft 41, and the other end is connected to the second circular ring 31. The plurality of second water supply blades 33 are distributed at intervals along the circumference of the rotating shaft 41. The second acceleration component 3 is rotated by the rotating shaft 41, and the second water supply blades 33 increase the driving force of the water flow, thereby improving the efficiency of the crushing, and cooperate with the first acceleration component 2 to support both ends of the rotating shaft 41, thereby improving the stability of the rotating shaft 41.

[0063] Reference Figure 2 and Figure 4 The inner wall of the straight tube 12 is provided with a coaxial second annular groove 1202. The second ring 31 is coaxially and rotatably disposed within the second annular groove 1202 and is dynamically sealed to the straight tube 12. The inner diameter of the second ring 31 is equal to that of the straight tube 12. The second ring 31 is embedded in the inner wall of the straight tube 12, preventing it from intercepting impurities.

[0064] Reference Figure 2 and Figure 4 A coaxial second sealed bearing 32 is connected between the second annular ring 31 and the straight tube 12 at both ends. The second sealed bearing 32 is located within the second annular groove 1202 and has an inner diameter equal to that of the straight tube 12. The second annular ring 31 is rotatably connected to the straight tube 12 via the second sealed bearing 32, creating a dynamic seal. This prevents impurities from entering the space between the second annular ring 31 and the straight tube 12 during rotation.

[0065] Reference Figure 2 and Figure 4 The outer wall of the straight tube 12 is provided with a driving assembly 5, and the driving assembly 5 includes a waterproof cover 51, a motor 52, a driving gear 53 and a driven gear 54. The motor 52 is installed in the waterproof cover 51. The driving gear 53 is connected to the motor 52. The driven gear 54 is coaxially installed on the outer wall of the first ring 21. A connecting through hole 1203 is provided at the bottom of the first annular groove 1201. After the driving gear 53 passes through the connecting through hole 1203, it engages with the driven gear 54. The waterproof cover 51 on the side of the connecting through hole 1203 is sealed to the straight tube 12. The motor 52 drives the driving gear 53 to rotate, and the driving gear 53 drives the driven gear 54, and then the driven gear 54 drives the first ring 21, thereby driving the first water supply blade 23 and the arc-shaped blade 42 to rotate.

[0066] The implementation principle of a suction pump head with a crushing function in the embodiment of the present application is as follows:

[0067] The drive assembly 5 rotates the first acceleration assembly 2, which in turn drives the second acceleration assembly 3 and the crushing assembly 4. The curved blades 42 rotate via the rotating shaft 41. When impurities such as plastic bags in the water flow pass through the water inlet pipe 1, the curved blades 42 effectively crush them. The staggered distribution along the length and circumference of the rotating shaft 41 increases the frequency of contact between the blades and solid particles, further enhancing the crushing effect. The first and second acceleration assemblies 2 and 3 are used to increase the water flow rate and the driving force of the water flow, thereby improving the crushing efficiency of the crushing assembly 4. This makes it less likely that the water pump will become clogged when pumping sewage.
