Description

Technical Field

[0001] This utility model relates to the technical field of pump pool dredging equipment, and more specifically, to a pump pool discharge outlet dredging device. Background Technology

[0002] In mineral mining, mineral processing, and similar industrial production fields involving slurry transportation, slurry pumps are critical conveying equipment, and their stable operation directly determines the continuity and efficiency of the production process. The pump pool, as the core component for temporary storage and buffering of slurry, is highly susceptible to blockage at the pump pool discharge outlet during actual operation due to the settling characteristics of solid particles (such as silt and ore fragments) in the slurry. This is especially true during short-term equipment shutdowns, reduced slurry flow rates, or when slurry particles have large diameters. Such blockages not only interrupt the slurry pump's supply, affecting the normal progress of subsequent production processes, but can also lead to pump overload, component wear, and other equipment failures, resulting in production stoppages and additional equipment maintenance costs. Therefore, timely and effective handling of pump pool discharge outlet blockages is a crucial aspect of ensuring stable industrial production.

[0003] The current mainstream approach in the industry for dealing with blockages at the slurry discharge port of the pump pool is as follows: When a blockage occurs, the operation of the slurry pump must be stopped first. After the equipment has been completely shut down, the feed pipe of the slurry pump is manually removed. Then, a high-pressure water pipe is used to extend into the pump pool from the removed feed port and flush out the deposited mud and other blockages by high-pressure water flow. After the blockage is cleared, the feed pipe is reinstalled and the slurry pump is restarted. However, the process requires a forced shutdown of the slurry pump, inevitably leading to an interruption of the entire production system and disrupting normal production order. This is especially problematic for companies with continuous production, where downtime results in significant capacity losses and time costs. Furthermore, the dismantling and reinstallation of the feed pipes rely on manual labor, increasing the workload of maintenance personnel. Additionally, if the blockage in the pump pool is suddenly cleared during manual flushing near the pump outlet, high-pressure water jets and rapid slurry outflow may occur, posing a significant risk to the safety of workers. Moreover, manual flushing from outside the pump pool by removing the feed inlet is limited by operating space and flushing angle, making it difficult to precisely target the core blockage area. This results in significant difficulty and low efficiency in clearing the blockage, often requiring multiple attempts and further extending equipment downtime. Utility Model Content

[0004] The purpose of this utility model is to provide a pump pool discharge outlet dredging device, which solves the problems of pump pool blockage requiring shutdown and pipe dismantling, high labor intensity and high safety risks.

[0005] This utility model is achieved through the following technical solution: a pump pool discharge outlet dredging device, including a first dredging mechanism, the first dredging mechanism including a main pipe connected to the outer end of the pump pool discharge outlet, the main pipe being provided with a first branch pipe inclined forward in the direction of water flow and a second branch pipe inclined backward in the direction of water flow, the first branch pipe being connected to a first high-pressure water pipe for reverse flushing and dredging the discharge outlet from the outside of the pump pool to the inside of the pump pool, and the second branch pipe being sealed and movably connected to a dredging rod.

[0006] Furthermore, the second branch pipe is sealed with a head via a flange. The head has a central hole for connecting a drain rod. The drain rod consists of a drain tip, a sliding section, a limiting ring, and a holding section, arranged sequentially from the inside to the outside of the second branch pipe. The end face of the drain tip is an elliptical surface cut at an angle. The inner wall of the central hole is limited by a sealing ring that slides and seals with the sliding section. The limiting ring abuts against the head.

[0007] Furthermore, a threaded section is provided between the unblocking tip and the sliding section, and the inner wall of the central hole is provided with an internal thread that is threaded to the threaded section for fastening the unblocking rod.

[0008] Furthermore, the gripping section includes an end and a straight rod connected to the limiting ring, the end being a spherical structure with anti-slip texture.

[0009] Furthermore, it includes a second dredging mechanism, which includes a second high-pressure water pipe installed on the inner wall of the pump pool, with a high-pressure nozzle inclined toward the discharge outlet at the lower end of the second high-pressure water pipe.

[0010] Furthermore, the first high-pressure water pipe and the second high-pressure water pipe are connected to the main pipe via a tee. A first switch valve is installed on the first high-pressure water pipe, a second switch valve is installed on the second high-pressure water pipe, and a third switch valve is installed on the main pipe.

[0011] Furthermore, the second high-pressure water pipe is attached to the inner wall of the pump pool in parallel with the bracket. The bracket has a through hole for the second high-pressure water pipe and the high-pressure nozzle to pass through. The second high-pressure water pipe is movably fitted with a limiting clamp that abuts against the bracket for positioning.

[0012] Furthermore, the high-pressure nozzle is detachably connected to the second high-pressure water pipe.

[0013] This utility model has at least the following advantages and beneficial effects: by setting a first branch pipe and a second branch pipe on the main pipe connected to the outer end of the ore discharge port of the pump pool, the first branch pipe is used to connect to the first high-pressure water pipe to flush the blockage of the ore discharge port from the outside to the inside of the pump pool, and the second branch pipe is used to seal and connect to the unblocking rod to mechanically break the blockage, thus constructing a synergistic mechanism of high-pressure flushing combined with mechanical unblocking, effectively reducing safety risks and downtime, and achieving efficient unblocking.

Detailed Implementation

[0019] The specific implementation method is described below with reference to the accompanying drawings.

[0020] Example like Figures 1 to 4As shown in this embodiment, a pump pool discharge outlet unblocking device is disclosed, including a first unblocking mechanism 1. The first unblocking mechanism 1 includes a main pipe 10 connected to the outer end of the pump pool discharge outlet. The main pipe 10 is provided with a first branch pipe 11 inclined forward in the direction of water flow and a second branch pipe 12 inclined backward in the direction of water flow. The first branch pipe 11 is connected to a first high-pressure water pipe 14 for reverse flushing and unblocking the discharge outlet from the outside to the inside of the pump pool. The second branch pipe 12 is sealed and movably connected to an unblocking rod 4. Specifically, the main pipe 10 has the same diameter as the outlet pipe of the pump pool discharge outlet and is sealed to it through a flange. The angle range between the first branch pipe 11 and the main pipe 10 and the angle range between the second branch pipe 12 and the main pipe 10 are both 30°~45°. The inclination direction of the first branch pipe 11 is consistent with the normal flow direction of the slurry, so that the high-pressure water transported by the first high-pressure water pipe 14 can reverse flush from the outside to the inside of the pump pool along this inclination angle (i.e., against the direction of slurry deposition), directly impacting the blockage at the discharge outlet. The second branch pipe 12 is inclined in the opposite direction to the slurry flow direction. Its sealingly connected unblocking rod 4 can extend along the axis of the second branch pipe 12 into the inside of the discharge port to mechanically break up harder blockages. The bidirectional inclined branch pipe structure establishes a synergistic mechanism of high-pressure flushing combined with mechanical unblocking. It uses reverse water flow to loosen blockages and reduce mechanical operating resistance, while mechanical force is used to handle harder blockages. This eliminates the need to disassemble pump components and shortens the operation path, effectively reducing safety risks and downtime, and achieving efficient unblocking.

[0021] Furthermore, in a specific implementation, the second branch pipe 12 provided in this embodiment of the present invention is sealed with a sealing head 13 via a flange. The sealing head 13 has a central hole for connecting the unblocking rod 4. The unblocking rod 4, from the inside to the outside of the second branch pipe 12, includes an unblocking tip 41, a sliding section 43, a limiting ring 44, and a holding section 45. The end face of the unblocking tip 41 is an elliptical surface cut at an angle. The inner wall of the central hole is limited by a sealing ring 131 that slides and seals with the sliding section 43. The limiting ring 44 abuts against the sealing head 13. Specifically, the unblocking tip 41 with its angled elliptical surface generates high pressure with a small contact area, making it easy to insert into the gap of the blockage. The flange and the sealing ring 131 achieve a double seal to prevent slurry leakage. The limiting ring 44 precisely controls the insertion depth of the unblocking tip 41 to prevent damage to the discharge pipe. The holding section 45 facilitates operation and control. During operation, the insertion, rotation, and withdrawal operations can be repeatedly combined to break the blockage. The overall process ensures the sealing, safety, and operational controllability of the mechanical dredging process.

[0022] Furthermore, in specific implementation, a threaded section 42 is provided between the aforementioned unblocking tip 41 and the sliding section 43 provided in this utility model embodiment. The inner wall of the central hole is provided with an internal thread that is threadedly connected to the threaded section 42 for fastening the unblocking rod 4. During operation, rotating the unblocking rod 4 can separate it from the sealing head 13, releasing the locking of the unblocking rod 4, and enabling the unblocking rod 4 to slide and break the blockage. When not in operation, rotating it in the opposite direction to tighten it locks the unblocking rod 4 and forms a static seal. This threaded engagement structure allows the unblocking rod 4 to have both active unblocking and fixed sealing states, which can be flexibly switched without additional locking components. This prevents the unblocking rod 4 from loosening due to vibration in the non-unblocking state, enhances the reliability of the seal, extends the service life of the sealing ring 131, and improves the practicality of the device.

[0023] Furthermore, in a specific implementation, the gripping section 45 provided in this embodiment of the present invention includes an end 451 and a straight rod 452 connected to the limiting ring 44. The end 451 is a spherical structure with anti-slip texture. The straight rod 452 provides a gripping fulcrum for operation, the spherical end 451 increases the contact area of ​​the hand, and the anti-slip texture enhances friction, allowing the operator to smoothly transmit torque through the straight rod 452 to switch the thread state, and also to use the spherical end 451 to stably exert force to push the unblocking rod 4, effectively preventing slippage in wet environments, reducing hand fatigue, and improving the convenience and stability of operation.

[0024] Furthermore, in specific implementation, the above-mentioned embodiment of this utility model includes a second unblocking mechanism 2, which includes a second high-pressure water pipe 21 mounted on the inner wall of the pump pool. The lower end of the second high-pressure water pipe 21 is connected to a high-pressure nozzle 22 inclined towards the discharge port. High-pressure water can be sprayed from the inside of the pump pool towards the discharge port, forming a three-dimensional flushing system of "inner positive impact + outer reverse peeling" with the reverse flushing of the outer side of the first branch pipe 11 in the first unblocking mechanism 1. The shearing force generated by the bidirectional water flow quickly disintegrates the blockage structure. Moreover, this mechanism can be started independently, is suitable for mild blockage scenarios, reduces the ineffective consumption of high-pressure water, and improves unblocking efficiency and flexibility.

[0025] Furthermore, in specific implementation, the first high-pressure water pipe 14 and the second high-pressure water pipe 21 provided in this utility model embodiment are connected to the main pipe 3 via a tee. A first switching valve 31 is provided on the first high-pressure water pipe 14, a second switching valve 32 is provided on the second high-pressure water pipe 21, and a third switching valve 33 is provided on the main pipe 3. During operation, by controlling the states of the first switching valve 31, the second switching valve 32, and the third switching valve 33, three modes can be switched: "external flushing alone" (first switching valve 31 and third switching valve 33 are open), "internal flushing alone" (second switching valve 32 and third switching valve 33 are open), and "coordinated internal and external flushing" (first switching valve 31, second switching valve 32, and third switching valve 33 are open). Furthermore, while the third switching valve 33 remains open, a gradient flushing effect can be achieved by controlling the opening sequence and time interval of the first switching valve 31 and the second switching valve 32. (For example, first open the first switch valve 31 (external flushing) to remove the surface deposits at the outer end of the discharge port, and then open the second switch valve 32 (internal flushing) after a 10-second interval to concentrate the water flow to impact the core blockage area on the inner side.) This adapts to different degrees of blockage (such as severe external accumulation and relatively light internal hardening), further improving the targeting and efficiency of dredging, while reducing the ineffective consumption of high-pressure water. The third switch valve 33 cuts off the main water supply during maintenance, improving operational safety and resource utilization.

[0026] Furthermore, in specific implementation, such as Figure 1 and Figure 4 As shown in the embodiment of this utility model, the second high-pressure water pipe 21 is parallel to and tightly attached to the inner wall of the pump pool via a bracket 5. The bracket 5 has a through hole 50 for accommodating the passage of the second high-pressure water pipe 21 and the high-pressure nozzle 22. A limiting clamp 51, which is positioned and abuts against the bracket 5, is movably sleeved on the second high-pressure water pipe 21. Specifically, at least two brackets 5 are arranged parallel to each other along the inner wall of the pump pool. The brackets 5 constrain the radial position of the second high-pressure water pipe 21 through the through hole 50. The limiting clamp 51 adopts existing technology; its outer edge engages with the outer edge of the through hole 50 to achieve axial positioning. Adjusting the position of the limiting clamp 51 changes the insertion depth of the second high-pressure water pipe 21 into the pump pool, ensuring that the high-pressure nozzle 22 is aligned with the discharge port. This structure achieves both radial fixation and axial adjustment of the second high-pressure water pipe 21, adapting to different specifications of pump pools and improving the versatility of the device.

[0027] Furthermore, in specific implementations, the high-pressure nozzle 22 and the second high-pressure water pipe 21 provided in this embodiment of the present invention are detachably connected. Specifically, the high-pressure nozzle 22 can be detachably connected to the end of the second high-pressure water pipe 21 using existing technology. When the high-pressure nozzle 22 is worn, clogged, or needs to be adapted to different blockage characteristics, the corresponding nozzle can be directly disassembled and replaced (e.g., a high-pressure direct-fire nozzle for hardened blockages, and a fan-shaped nozzle for loose accumulations), without needing to replace the entire water pipe, saving material costs. It also facilitates daily cleaning and maintenance, extends the service life of the device, and improves maintenance convenience and functional expandability.
