Description

Technical Field

[0001] This utility model relates to the field of hydrocyclone technology, specifically to an easy-to-unclog hydrocyclone pipe. Background Technology

[0002] Hydrocyclones, as typical devices utilizing a combined centrifugal and gravitational force field, are widely used in many fields due to their advantages such as simple structure, small footprint, convenient installation and operation, and low operating costs. For example... Figure 1 The hydrocyclone shown has an inlet on the upper left side of its outer wall and an outlet on the top wall. Its basic principle is to separate two-phase or multi-phase mixtures (such as liquid-liquid or liquid-solid mixtures) with a certain density difference under centrifugal force. The mixture enters the hydrocyclone tangentially through the inlet at a certain pressure, generating a high-speed rotating flow field within the cylindrical cavity. The denser components in the mixture move simultaneously axially downwards and radially outwards under the influence of this swirling flow field. Upon reaching the conical section, they move downwards along the inner wall of the hydrocyclone and exit through the bottom outlet, thus forming an outer vortex flow field. The less dense components move towards the central axis, forming an upward-moving inner vortex at the center of the axis, and then exit through the outlet, thereby achieving two-phase separation.

[0003] During hydrocyclone operation, the presence of numerous colloidal particles, flocculent matter, and other impurities in the treatment medium of the sludge and sand treatment unit frequently leads to blockages at the hydrocyclone's inlet, overflow, and underflow outlet. (Continue to refer to...) Figure 1 When blockage occurs at the inlet or overflow port, operators need to close the inlet and outlet valves, remove the fixing bolts of the inlet flange 17, overflow flange 18, and underflow flange 19, disassemble the entire hydrocyclone, remove the blockage from the inlet or overflow port, and allow the blockage to drain from the underflow flange 19. Unblocking takes at least 1.5 hours. If the underflow port is blocked, the fixing bolts of the underflow flange 19 need to be removed, and debris removed from the underflow port. Unblocking takes at least 1 hour, affecting the operating efficiency of the treatment unit. Furthermore, due to the confined space and high oil content around the underflow port, operation is extremely inconvenient for operators, resulting in a significant workload and increased difficulty. Utility Model Content

[0004] To address the aforementioned shortcomings in existing technologies, this utility model aims to provide an easy-to-unclog hydrocyclone pipe, enabling workers to conveniently and quickly clear blockages at the hydrocyclone inlet and outlet, thereby reducing the workload and difficulty of the work.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an easy-to-unclog hydrocyclone pipe, including an overflow pipe fixedly connected to an overflow port opened on the top wall of the hydrocyclone, and an overflow tee fitting. The end of the overflow pipe away from the hydrocyclone is detachably connected to one of the joints of the overflow tee fitting, and the other two joints of the overflow tee fitting, which are coaxially arranged with the overflow pipe, are detachably connected to overflow unclogging valves.

[0006] As a limitation of this utility model: the easy-to-unclog hydrocyclone pipe also includes an inlet pipe fixedly connected to the inlet port opened on the upper part of the hydrocyclone side wall, and an inlet tee fitting. The end of the inlet pipe away from the hydrocyclone is detachably connected to one of the joints of the inlet tee fitting. The other two joints of the inlet tee fitting, which are coaxially arranged with the inlet pipe, are detachably connected to inlet unblocking valves.

[0007] As a limitation of this utility model: one of the other two connectors of the overflow tee fitting is detachably connected to an outlet pipe, and an outlet valve is fixedly installed on the outlet pipe.

[0008] As a limitation of this utility model: one of the other two connectors of the inlet tee fitting is detachably connected to an inlet pipe, and an inlet valve is fixedly installed on the inlet pipe.

[0009] As a limitation of this utility model: the easy-to-dredge hydrocyclone pipe also includes an underflow pipe fixedly connected to the underflow port opened at the bottom of the hydrocyclone, the size of the overflow port is equal to or greater than the size of the underflow port, the overflow port and the underflow port are coaxially arranged, and the inner diameter of the overflow unblocking valve after it is fully opened is equal to or greater than the size of the overflow port.

[0010] As a limitation of this utility model: the inner diameter of the inlet unblocking valve after it is fully opened is equal to or greater than the size of the inlet, and the inlet unblocking valve and the inlet are coaxially arranged.

[0011] As a limitation of this utility model, both the overflow drain valve and the inlet drain valve are ball valves.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: By optimizing the pipes at the inlet and outlet of the hydrocyclone and improving the ordinary elbow pipe into a tee pipe, when clearing blockages, a steel bar is inserted into the ball valve connected to the tee pipe. This allows for convenient and quick removal of blockages at the inlet, overflow, or underflow outlet without disassembling the hydrocyclone. The hydrocyclone with the above structure not only reduces the workload and difficulty of the work, and alleviates the labor intensity of the workers, but also allows the unblocking process to be completed in less than 10 minutes. Compared with disassembling the hydrocyclone before unblocking, the work efficiency is increased by more than 9 times, greatly shortening the unblocking time and improving the operating efficiency of the hydrocyclone.

It should be understood that the easily unclogged hydrocyclone pipe described herein is a preferred embodiment and is only used for illustration and explanation of this utility model, and does not constitute a limitation thereof.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0019] like Figure 2As shown, the hydrocyclone includes a hydrocyclone body with an inlet 1 on the upper side wall, an overflow 2 on the top wall, and a bottom outlet 3. The easily navigable hydrocyclone piping includes an inlet pipe 4 fixedly connected to the inlet 1 for conveying the mixture, an overflow pipe 5 fixedly connected to the overflow 2 for discharging low-density substances, and a bottom outlet 6 fixedly connected to the bottom outlet 3 for discharging high-density substances. The mixture enters the hydrocyclone through the inlet 1, and after centrifugal motion, the low-density substances are discharged from the hydrocyclone through the overflow 2, while the high-density substances are discharged from the hydrocyclone through the bottom outlet 3.

[0020] The hydrocyclone piping in this embodiment also includes an overflow tee fitting 7 and an inlet tee fitting 10. At the three joints of the tee fitting, a detachable connection between the pipe and the joints is achieved through plug-in or flange connections. In this embodiment, the pipe is detachably connected to the tee fitting via a flange. By connecting pipes with different functions to the other two joints of the tee fitting away from the hydrocyclone, convenient and quick unblocking of the hydrocyclone's clogged areas can be achieved.

[0021] Specifically, the end of the overflow pipe 5 furthest from the hydrocyclone is detachably connected to one of the joints of the overflow tee fitting 7. The other two joints of the overflow tee fitting 7, coaxially arranged with the overflow pipe 5, are detachably connected to overflow drain valves 9. For cases with long material conveying paths, an appropriate length of overflow drain pipe 8 can be detachably connected between the joint and the overflow drain valve 9 to meet the needs of long-distance material conveying. The overflow drain valve 9 is detachably connected to the end of the overflow drain pipe 8 furthest from the hydrocyclone. The other joint of the overflow tee fitting 7 is detachably connected to an outlet pipe 13, on which an outlet valve 14 is fixedly installed.

[0022] The end of the inlet pipe 4 furthest from the hydrocyclone is detachably connected to one of the joints of the inlet tee fitting 10. The other two joints of the inlet tee fitting 10, coaxially aligned with the inlet pipe 4, are detachably connected to inlet unblocking valves 12. For longer material transport paths, an appropriate length of inlet unblocking pipe 11 can be detachably connected between the joint and the inlet unblocking valve 12 to meet the needs of long-distance material transport. The inlet unblocking valve 12 is detachably connected to the end of the inlet unblocking pipe 11 furthest from the hydrocyclone. The other joint of the other two joints of the inlet tee fitting 10 is detachably connected to an inlet pipe 15, on which an inlet valve 16 is fixedly installed. Preferably, both the overflow unblocking valve 9 and the inlet unblocking valve 12 are ball valves, whose internal space after opening allows slender steel bars to pass through.

[0023] The overflow port 2 is equal to or larger than the bottom outlet 3. The overflow port 2 and the bottom outlet 3 are coaxially arranged. The inner diameter of the overflow pipe 8 and the inner diameter of the overflow valve 9 after it is fully opened are both equal to or larger than the overflow port 2, so that the reinforcing bars can pass smoothly through the aforementioned orifice. The inner diameter of the inlet pipe 11 and the inner diameter of the inlet valve 12 after it is fully opened are both equal to or larger than the inlet port 1. The inlet pipe 11 and the inlet port 1 are coaxially arranged, so that the reinforcing bars can pass smoothly through the aforementioned orifice.

[0024] When the hydrocyclone is working, the overflow valve 9 and the inlet valve 12 are normally closed, while the inlet valve 16 and the outlet valve 14 are normally open. When the operator finds that the flow rate at the bottom outlet 3 has decreased or stopped, it indicates that the bottom outlet 3 is blocked. At this time, the inlet valve 16 and the outlet valve 14 can be closed, and the overflow valve 9 can be opened. A steel bar with an outer diameter smaller than the bottom outlet 3 and the internal size of the overflow valve 9 can be used to pass through the overflow valve 9, the overflow pipe 8, and the overflow outlet 2 from top to bottom until it reaches the vicinity of the bottom outlet 3. Move the steel bar back and forth to pry out the blockage at the bottom outlet 3. Then, withdraw the steel bar, close the overflow valve 9, and open the inlet valve 16 and the outlet valve 14 to unblock the bottom outlet 3.

[0025] When staff find that the flow rate of the bottom outlet 3 and the overflow outlet 2 decreases or stops at the same time, it indicates that the inlet 1 is blocked. At this time, the inlet valve 16 and the outlet valve 14 can be closed, and the inlet unblocking valve 12 can be opened. A steel bar with an outer diameter smaller than the inlet 1 and the internal size of the inlet unblocking valve 12 can be passed through the inlet unblocking valve 12 and the inlet unblocking pipe 11 from left to right until it reaches the vicinity of the inlet 1. Move the steel bar back and forth to poke out the blockage in the inlet 1. Then, withdraw the steel bar, close the inlet unblocking valve 12, and open the inlet valve 16 and the outlet valve 14 to achieve the unblocking operation of the inlet 1.

[0026] The low-density substance separated by the hydrocyclone is discharged from the outlet pipe 13 and enters the canister-shaped metal container. A pump connected to the container is used to extract the liquid stored inside for subsequent steps. A level gauge connected to the container indicates the liquid level. When the operator observes a significant drop in the liquid level and a decrease in the pump's flow rate, it indicates a blockage at the overflow port 2. In this case, the inlet valve 16 and outlet valve 14 can be closed, and the overflow unblocking valve 9 can be opened. A steel bar with an outer diameter smaller than the internal size of the overflow unblocking valve 9 can be inserted from top to bottom through the overflow unblocking valve 9 and overflow pipe 8 until it reaches the vicinity of the overflow port 2. The steel bar can be moved back and forth to dislodge the blockage. The steel bar can then be withdrawn, the overflow unblocking valve 9 closed, and the inlet valve 16 and outlet valve 14 opened, thus unblocking the overflow port 2.

[0027] This embodiment optimizes the pipes at the inlet and outlet of the hydrocyclone, replacing ordinary elbows with tees. When clearing blockages, a reinforcing bar is inserted into the ball valve connected to the tee, allowing for convenient and quick removal of blockages at the inlet 1 or outlet 3 without disassembling the hydrocyclone. This hydrocyclone structure not only reduces the workload and difficulty for workers, alleviating their labor intensity, but also allows for unblocking operations to be completed in less than 10 minutes. Compared to disassembling the hydrocyclone before unblocking, this increases work efficiency by more than nine times, significantly shortening unblocking time and improving the hydrocyclone's operating efficiency.
