Description

Technical Field

[0001] This utility model relates to water conservancy engineering equipment technology, specifically to a pump anti-clogging cutter with a debris rejection function. Background Technology

[0002] In fields such as sewage treatment, industrial fluid transportation, and agricultural irrigation, pumps are often used, such as sewage pumps and submersible pumps, which are core fluid transportation and processing devices. Their working environment often contains fibrous debris, such as hemp rope, plastic bags, hair, and blocky solids including gravel and domestic waste. These debris can easily accumulate in the pump body or entangle moving parts, leading to a decrease in pump efficiency or even failure.

[0003] However, although existing submersible pumps have an integrated cutting mechanism at the suction port, they use an internal axial cutting blade powered by a water pump. During the pumping process, hard objects can block the suction port, obstructing it. This can also cause flexible objects to be blocked, leading to blockages at the suction port. This can cause the cutting mechanism to jam, reducing the pumping volume and causing considerable inconvenience for users. Utility Model Content

[0004] The purpose of this invention is to provide a pump anti-clogging cutter with a debris rejection function, in order to solve the problem that existing submersible pumps use an internal axial cutter, with the power source coming from the water pump. During the pumping process, hard objects can block the water inlet, causing obstruction of the inlet and making it easy to intercept and block flexible objects, preventing the cutting mechanism from performing cutting operations, and easily causing blockage at the water inlet, thus reducing the pumping volume.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pump anti-clogging cutter with a debris rejection function, comprising a water suction head mechanism and a grid mechanism assembled on the top of the water suction head mechanism, and a cutting mechanism assembled inside the water suction head mechanism, wherein the water suction head mechanism includes a water suction cover, and a mounting base is provided on one side of the water suction cover;

[0006] The grid mechanism includes a mounting ring fixedly installed on the top of the water absorption cover, and grid strips are fixedly installed inside the mounting ring. The grid strips are arc-shaped and convex upwards. Cutting openings are provided between the grid strips.

[0007] The cutting mechanism includes a shaft frame fixedly installed at the bottom of the mounting ring, a rotating rod rotatably installed between the shaft frames, a mounting sleeve fixedly installed around the rotating rod, a cutting blade fixedly installed on the surface of the mounting sleeve, and the cutting blade extending into the shearing opening.

[0008] Furthermore, a protective cover is fixedly installed on one side of the mounting base, and a driving component corresponding to the rotating rod is fixedly installed inside the protective cover.

[0009] Furthermore, the mounting base has a through hole for the rotating rod to pass through, and the shaft bracket and the rotating rod are rotatably mounted together via bearings.

[0010] Furthermore, the bottom of the water-absorbing cover is connected to a connecting pipe, and a flange is fixedly installed at the bottom of the connecting pipe.

[0011] Furthermore, the mounting ring is fixedly installed to the water-absorbing cover by a fixing bolt, and the surface of the mounting ring is provided with a mounting groove.

[0012] Furthermore, the shaft bracket is fixedly installed to the mounting groove by bolts, and the top of the shaft bracket is provided with a threaded hole for the bolt threads to engage.

[0013] Furthermore, the mounting sleeve and the rotating rod are fixedly installed together by mounting bolts, and the cutting blades are arranged in a spiral shape.

[0014] Compared with existing technologies, the anti-clogging cutter for pumps with debris rejection function provided by this utility model, through the cooperation between the grid mechanism and the cutting mechanism, can intercept and block various debris in the fluid through the grid bars. By driving the cutting blade to rotate, the cutting blade can rotate within the shearing opening, forming a shearing effect with the grid bars, which can easily cut and break up the debris. At the same time, by utilizing the upward convex arc shape of the grid bars and the arc blade of the cutting blade, the angle between the grid bars and the cutting blade during shearing is large, which can easily squeeze out hard objects that cannot be cut, and it is not easy to cause the cutting blade to jam. This can effectively prevent clogging, ensure that the pumping volume is not reduced, and improve the use effect.

[0015] With its suction head mechanism, the device can be connected to the water pump's suction port via a hose, allowing for convenient separate use from the pump. This enables the device to be driven independently without relying on the pump's power source, effectively increasing the pump's operating power and ensuring a relatively stable pumping volume, thus providing greater convenience for users.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] Example 1:

[0028] This utility model provides a pump anti-clogging cutter with a debris rejection function, including a water suction head mechanism 2 and a grid mechanism 1 mounted on the top of the water suction head mechanism 2, and a cutting mechanism 3 mounted inside the water suction head mechanism 2. The water suction head mechanism 2 includes a water suction cover 21, and a mounting seat 25 is provided on one side of the water suction cover 21.

[0029] The grid mechanism 1 includes a mounting ring 11 fixedly installed on the top of the water absorption cover 21. A grid strip 14 is fixedly installed inside the mounting ring 11. The grid strip 14 is arc-shaped and convex upward. A shearing opening 15 is provided between the grid strips 14.

[0030] The cutting mechanism 3 includes a shaft frame 31 fixedly installed at the bottom of the mounting ring 11, a rotating rod 32 rotatably installed between the shaft frames 31, a mounting sleeve 33 fixedly installed around the rotating rod 32, a cutting blade 35 fixedly installed on the surface of the mounting sleeve 33, and the cutting blade 35 extending into the shearing opening 15.

[0031] As can be seen from the above, by connecting the suction hood 21 to the water pump's suction port through a hose, the suction hood 21 can be placed into the fluid to be pumped. The water pump generates suction, allowing the fluid to enter the suction hood 21 for pumping. This allows the device and the water pump to be used separately, enabling the device to be driven by its own power source without relying on the water pump's power source. This effectively improves the water pump's operating power and ensures a relatively stable pumping volume, bringing greater convenience to users.

[0032] During the pumping process, the grid strips 14 can block larger debris, preventing it from entering the suction hood 21 and causing the cutting blade 35 to jam. The shaft bracket 31 can be fixed to the bottom of the mounting ring 11, and the shaft bracket 31 can support the rotating rod 32, allowing the rotating rod 32 to rotate inside the suction hood 21. The rotation of the rotating rod 32 synchronously drives the cutting blade 35 to rotate, allowing the cutting blade 35 to rotate within the shearing opening 15. This creates a shearing effect between the cutting blade 35 and the grid strips 14, facilitating the shearing and crushing of debris. Furthermore, the arc-shaped upward protrusion of the grid strips 14, combined with the arc-shaped blade of the cutting blade 35, creates a larger shearing angle between the grid strips 14 and the cutting blade 35. This allows hard objects that cannot be sheared to be easily squeezed out, preventing the cutting blade 35 from jamming. This effectively ensures that the shearing opening 15 is not easily blocked, maintaining a consistent pumping volume and improving the overall performance.

[0033] From the appendix Figure 2 and attached Figure 5 It can be seen that a protective cover 37 is fixedly installed on one side of the mounting base 25, and a driving component 38 corresponding to the rotating rod 32 is fixedly installed inside the protective cover 37.

[0034] As can be seen from the above, the mounting base 25 can conveniently provide an installation area for the protective cover 37, and can easily fix the protective cover 37 to one side of the water suction cover 21. The drive component 38 is a motor that can be installed inside the protective cover 37. The protective cover 37 can provide waterproof protection for the drive component 38. The water suction cover 21 can be immersed in water for water pumping operation. The drive component 38 can provide power to the rotating rod 32 independently, which can easily drive the rotating rod 32 to rotate, so that the rotating rod 32 can drive the cutting blade 35 to rotate and perform shearing and crushing operations on the debris.

[0035] For details, please refer to the appendix. Figure 3 and attached Figure 5 As shown, the mounting base 25 has a through hole 24 for the rotating rod 32 to pass through, and the shaft bracket 31 and the rotating rod 32 are rotatably mounted together via a bearing 39.

[0036] As can be seen from the above, by passing the rotating rod 32 through the through hole 24, one end of the rotating rod 32 can be extended into the protective cover 37, so that the rotating rod 32 can be connected to the output shaft of the drive component 38, so that the drive component 38 can easily drive the rotating rod 32 to rotate. The bearing 39 can make the rotating rod 32 rotate stably in the shaft frame 31, so that the rotating rod 32 is not easy to wobble when rotating.

[0037] For details, please refer to the appendix. Figure 3 As shown, the bottom of the water absorption cover 21 is connected to a connecting pipe 22, and a flange 23 is fixedly installed at the bottom of the connecting pipe 22.

[0038] As can be seen from the above, the flange 23 can be easily connected to the water pump hose, and the connecting pipe 22 can be connected to the water pump hose. When the water pump is running, the suction hood 21 can easily generate suction force, which can facilitate the water pumping operation.

[0039] Working principle: By connecting the water suction hood 21 to the water pump's suction hose, the water suction hood 21 is placed underwater. The water pump generates suction in the water suction hood 21, enabling water pumping. The grid bars 14 intercept impurities in the water. The drive unit 38 drives the rotating rod 32 to rotate, which in turn drives the cutting blade 35 to rotate. The cutting blade 35 rotates along the shearing opening 15, cutting and breaking up the debris intercepted on the surface of the grid bars 14. At the same time, the large angle between the grid bars 14 and the cutting blade 35 during shearing allows hard objects that cannot be cut to be squeezed out, preventing blockages and avoiding jamming of the cutting blade 35, effectively ensuring a stable water pumping effect.

[0040] Example 2:

[0041] Reference Appendix Figure 1 Appendix Figure 4 and attached Figure 5 As shown, the mounting ring 11 and the water absorption cover 21 are fixedly installed by a fixing bolt 12, and the surface of the mounting ring 11 is provided with a mounting groove 16.

[0042] As can be seen from the above, the mounting ring 11 can be easily fixed to the top of the water suction cover 21 by the fixing bolt 12, and the grid strip 14 can be easily covered on the surface of the water suction cover 21. It can intercept impurities in the water during the water pumping process. The mounting groove 16 can provide an installation position for the cutting mechanism 3, and can make the cutting mechanism 3 run stably without shaking.

[0043] Reference Appendix Figure 5 and attached Figure 6 As shown, the shaft bracket 31 is fixedly installed with the mounting groove 16 by bolts 36, and the top of the shaft bracket 31 is provided with a threaded hole 310 for the bolts 36 to engage.

[0044] As can be seen from the above, the bolt 36 passes through the mounting groove 16 from top to bottom, so that the bottom position of the bolt 36 can extend into the threaded hole 310. By using a wrench or other tools to rotate the bolt 36, the bolt 36 can be threaded into the threaded hole 310. The bolt 36 can be used to lock the shaft bracket 31 at the bottom position of the mounting ring 11, and it is also convenient for disassembly operations, which brings more convenience to maintenance work.

[0045] Reference Appendix Figure 5 As shown, the mounting sleeve 33 and the rotating rod 32 are fixedly installed by mounting bolts 34, and the cutting blades 35 are arranged in a spiral shape.

[0046] As can be seen from the above, the mounting sleeve 33 can be easily fixed to the surface of the rotating rod 32 by the mounting bolt 34, so that when the rotating rod 32 rotates, it can drive the mounting sleeve 33 to rotate, which can synchronously drive the cutting blade 35 to rotate. Through the spirally arranged cutting blade 35, it is convenient to alternately cut the debris on the surface, which can effectively improve the cutting effect. When encountering large hard objects that cannot be cut, it can make the hard objects have enough space to be squeezed out, effectively preventing blockage.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
