Description

Technical Field

[0001] This utility model relates to the field of hydrocyclones, specifically a water treatment hydrocyclone device. Background Technology

[0002] A hydrocyclone is a static separation device with no moving parts that utilizes the principle of centrifugal force. It is simple in structure and highly efficient. Through high-speed rotation, it forces the solid / liquid / liquid / gas mixtures to separate internally based on density or particle size differences. This enables efficient classification, such as separating coarse and fine particles in mineral slurry, concentrating to increase the solid content of suspensions, or separation in key industrial processes such as oil-water separation, sand removal, and desliming. It is widely used in many fields such as mining and mineral processing, environmental water treatment, petrochemicals, and food processing.

[0003] Existing hydrocyclone devices for water treatment separate sand and liquid during use. However, as the usage time increases, a layer of residual dirt forms on the inner wall of the hydrocyclone, affecting its normal operation. This requires workers to disassemble and clean it, reducing work efficiency. Therefore, the inventors urgently need to design a device that can clean the inner wall of the hydrocyclone to improve work efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a water treatment hydrocyclone device to solve the technical problem of low cleaning efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water treatment hydrocyclone device, comprising a conical outer shell, wherein a plurality of cleaning mechanisms are inserted into the lower outer side of the conical outer shell, the cleaning mechanism comprising a pipe, the pipe being obliquely inserted through the conical outer shell, a high-pressure solenoid valve being provided at one end of the pipe, a timer control module being provided below the high-pressure solenoid valve, a water inlet being provided at one end of the pipe, and a nozzle being provided at the other end of the pipe.

[0006] By adopting the above technical solution, a cleaning mechanism is obliquely integrated into the key area of ​​the conical shell, achieving a breakthrough in online cleaning of the inner wall of the hydrocyclone without disassembly. This design allows the high-pressure cleaning fluid to act directly on the conical wall surface where dirt is most severely deposited, using the jet impact force to physically peel off the attached sand particles, greatly reducing the frequency of manual cleaning and downtime.

[0007] Furthermore, the high-pressure solenoid valve is used to quickly cut off or connect the high-pressure water flow, and the outer shell of the high-pressure solenoid valve is made of stainless steel.

[0008] By adopting the above technical solution, the high-pressure solenoid valve with a stainless steel shell gives the system reliable control capability under extreme working conditions. The stainless steel material is resistant to corrosion from sandy sewage and high-pressure water hammer impact, ensuring that the valve can be opened and closed stably in the high-frequency vibration environment of the hydrocyclone, and preventing cleaning fluid leakage or pressure loss due to valve failure.

[0009] Furthermore, the timing control module is used to control the start and stop of the cleaning mechanism's operation.

[0010] By adopting the above technical solutions, the independent timed control module establishes a fully automated cleaning decision-making mechanism, and realizes unattended operation and maintenance through preset programs. Users can set the optimal cleaning cycle according to the water hardness, avoiding over-cleaning or under-cleaning problems caused by misjudgment due to manual monitoring.

[0011] Furthermore, a high-pressure water pump is connected to the water inlet, and the other end of the high-pressure water pump is connected to an external cleaning fluid storage device.

[0012] By adopting the above technical solution, the external high-pressure water pump and the cleaning fluid storage device form an expandable media adaptation system. By changing the type of cleaning agent in the storage device, such as acidic calcium remover / alkaline degreaser, different types of dirt can be treated in a targeted manner, breaking through the physical property limitations of single hydraulic flushing.

[0013] Furthermore, a fixing nut is provided below the nozzle, which is locked to the inner wall of the conical shell to restrict the position of the cleaning mechanism.

[0014] By adopting the above technical solution, the snap-in positioning structure of the fixing nut achieves precise three-dimensional positioning of the nozzle. Its inner wall snap-fit ​​design ensures that the spray axis always points to the normal direction of the cone generatrix, so that the core impact zone of the jet always covers the surface with the highest probability of scaling.

[0015] Furthermore, a protective cover is provided on the outside of the nozzle to protect the nozzle.

[0016] By adopting the above technical solution, a protective barrier is constructed. Its open structure ensures smooth water flow during spraying, while the closed state isolates solid particles from contact. This not only solves the industry pain point of nozzles being worn and failing by sand particles during separation operation, but also avoids sacrificing the jet coverage during cleaning.

[0017] Furthermore, a sand settling port is provided at the bottom of the conical outer shell, a cylindrical outer shell is connected to the top of the conical outer shell, and an overflow port is connected to the top of the cylindrical outer shell.

[0018] By adopting the above technical solution, the cone-cylinder dual-shell coupling design optimizes the synergistic effect of the graded flow field and cleaning effect. The cylindrical shell stabilizes the swirling flow field, improves the initial separation efficiency, and reduces the total amount of impurities diffusing into the cone section. The inclined wall of the cone section enhances the reflection of the cleaning liquid jet and generates a wall shear acceleration effect.

[0019] Furthermore, a feed port is provided on one side of the upper end of the cylindrical shell, and a filter grid is inclinedly arranged inside the feed port. The filter grid is used to filter large stones.

[0020] By adopting the above technical solutions, the inclined grid forms a multi-level defense system at the feed port. The inclined angle design allows large stones to slide off the screen surface under their own weight. Combined with the high-frequency self-vibration mechanism, it achieves zero-clogging filtration and reduces the mechanical wear rate of the hydrocyclone from the source.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model achieves automatic cleaning without disassembly through a cleaning mechanism that is obliquely inserted on the outside of a conical shell. The through-pipe design in the cleaning mechanism allows high-pressure water to act directly on the scaled area on the inner wall, using jet impact to remove sand deposits, greatly reducing the frequency of downtime and disassembly. At the same time, the timer control module automatically starts and stops the high-pressure solenoid valve and water pump according to a preset cycle, ensuring that the cleaning process is completed without human intervention, significantly reducing the need for manual intervention and operational safety hazards.

[0023] 2. This utility model improves system reliability through multiple structural designs. The inclined filter screen intercepts large stones and other debris at the feed port, preventing blockage or damage to components in the main separation zone. The high-pressure solenoid valve uses a stainless steel shell to enhance corrosion resistance and adapt to high solids wastewater treatment environments. The fixing nut precisely anchors the nozzle position at the designed coordinate point on the cone wall, ensuring that the jet direction is perpendicular to the dirt accumulation surface and maximizing the impact effect.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] In this embodiment:

[0031] A water treatment hydrocyclone device, such as Figure 1-4 As shown, the device includes a conical outer shell 2, with several cleaning mechanisms 7 inserted into the lower outer side of the conical outer shell 2. Each cleaning mechanism 7 includes a pipe 701, which is obliquely inserted through the conical outer shell 2. A high-pressure solenoid valve 702 is installed at one end of the pipe 701, and a timer control module 703 is installed below the high-pressure solenoid valve 702. A water inlet 704 is installed at one end of the pipe 701, and a nozzle 706 is installed at the other end. The cleaning mechanisms are obliquely integrated in the key area of ​​the conical outer shell, achieving a breakthrough in online cleaning of the hydrocyclone's inner wall without disassembly. This design allows the high-pressure cleaning fluid to act directly on the conical section wall where the dirt deposits are most severe, using the jet impact force to physically peel off the attached sand particles, significantly reducing the frequency of manual cleaning and downtime. At the same time, the through-pipe structure creates the shortest fluid path, reducing pressure loss and ensuring jet intensity. Furthermore, the coordinated layout of multiple cleaning mechanisms can cover areas with different heights of fouling. This modular embedding method preserves the original flow field characteristics of the hydrocyclone to the maximum extent, avoids the risk of seal damage caused by traditional disassembly methods, and significantly extends the service life of the equipment.

[0032] See Figure 3 The high-pressure solenoid valve 702 is used to quickly cut off or connect high-pressure water flow. The housing of the high-pressure solenoid valve 702 is made of stainless steel. The stainless steel housing of the high-pressure solenoid valve gives the system reliable control capability under extreme working conditions. The stainless steel material is resistant to corrosion from sandy sewage and impact from high-pressure water hammer, ensuring stable opening and closing of the valve in the high-frequency vibration environment of the hydrocyclone. It eliminates the leakage of cleaning fluid or pressure loss due to valve failure. At the same time, the electromagnetic drive achieves a fast response speed. When used with the timing module, it can perform precise instantaneous flushing operation, which can efficiently remove the initial soft scale without interfering with normal separation operation. This active fast cut-off mechanism reduces energy consumption compared with traditional manual valves and eliminates the risk of secondary scaling caused by continuous leakage from the root.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The timing control module 703 is used to control the start and stop of the cleaning mechanism 7. The independent timing control module establishes a fully automated cleaning decision mechanism and realizes unattended operation and maintenance through preset programs. Users can set the optimal cleaning cycle according to the water hardness to avoid over-cleaning or under-cleaning caused by misjudgment due to manual monitoring. At the same time, the hard linkage design of this module and the solenoid valve constructs a closed-loop control system, and the trigger command is directly converted into the execution action, eliminating the signal delay of the traditional PLC system. In case of sudden working conditions such as abnormal sand caking, the emergency cleaning mode can be manually activated. The multi-level control logic ensures that the system meets both daily routine maintenance and emergency handling capabilities.

[0034] See Figure 3 The water inlet 704 is connected to a high-pressure water pump, and the other end of the high-pressure water pump is connected to an external cleaning fluid storage device. The external high-pressure water pump and the cleaning fluid storage device form an expandable media adaptation system. By changing the type of cleaning agent in the storage device, such as acidic calcium remover / alkaline degreaser, different types of dirt can be treated in a targeted manner, breaking through the physical property limitations of single hydraulic flushing. At the same time, the modular separation design avoids the vibration interference problem of the built-in pump body. The independent foundation installation of the water pump group ensures that pressure pulsation is not transmitted to the hydrocyclone body. This solution allows users to dynamically adjust the output pressure according to the degree of scaling, achieving the best balance between powerful removal of hard scale and protection of the inner wall coating.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixing nut 705 is provided below the nozzle 706. The fixing nut 705 is snapped into the inner wall of the conical shell 2 to limit the position of the cleaning mechanism 7. The snap-in positioning structure of the fixing nut enables precise three-dimensional positioning of the nozzle. Its inner wall snap-fit ​​design ensures that the spray axis always points to the normal direction of the generatrix of the cone, so that the core impact zone of the jet always covers the surface with the maximum probability of fouling. At the same time, the mechanical constraint force can resist the action of the tangential force of the swirling flow and solve the problem of thermal deformation and displacement of conventional welding installation. The device only requires a single tightening operation during installation and the entire pipe can be pulled out by loosening the nut during maintenance. Compared with the flange connection scheme, it shortens the disassembly and assembly time and is particularly suitable for confined space operations such as underground and high-altitude operations.

[0036] See Figure 4 A protective cover 707 is provided on the outside of the nozzle 706. The protective cover 707 is used to protect the nozzle 706 and build a protective barrier. Its open structure ensures smooth water flow during spraying, and isolates solid particles from contact when closed. This not only solves the industry pain point of nozzles being worn and failed by sand particles during separation operation, but also avoids sacrificing the jet coverage during cleaning. At the same time, the arc-shaped flow guiding design of the cover body significantly reduces the impact noise of liquid-solid two-phase flow, so that the fluid forms a self-cleaning vortex in the cover cavity. When the valve is closed, the high-speed rewind carries away residual particles, completely solving the problem of permanent blockage caused by sand accumulation in traditional nozzles when the machine stops.

[0037] See Figure 1 , Figure 2 , Figure 3The conical shell 2 has a sedimentation port 5 at its bottom and a cylindrical shell 1 at its top. The cylindrical shell 1 has an overflow port 4 at its top. The cone-cylinder dual-shell coupling design optimizes the graded flow field and the cleaning effect. The cylindrical shell stabilizes the swirling flow field, improves the initial separation efficiency, and reduces the total amount of impurities diffused into the cone section. The inclined wall of the cone section enhances the reflection of the cleaning liquid jet and generates a wall shear acceleration effect. At the same time, the special diffusion structure of the sedimentation port automatically turns into a sewage discharge channel in the cleaning mode. Its inverted funnel shape uses the Venturi effect to accelerate the discharge of dirt. The double curvature transition section of the overflow port eliminates the risk of siphoning of cleaning liquid into clean water and ensures water quality stability when switching between separation operations and cleaning modes.

[0038] See Figure 1 , Figure 2 A feed port 3 is provided on one side of the upper end of the cylindrical outer shell 1. A filter grid 6 is inclinedly arranged inside the feed port 3. The filter grid 6 is used to filter large stones. The inclined grid forms a multi-level defense system at the feed port. The inclined angle design allows large stones to slide off the screen surface under their own weight. Combined with the high-frequency self-vibration mechanism, zero-clogging filtration is achieved, reducing the mechanical wear rate of the hydrocyclone from the source. At the same time, the vortex effect generated by the grid interception forms a pre-separation field in the feeding area, causing fine sand particles to accumulate on the pipe wall in advance, reducing the cleaning pressure of the subsequent cone section. This structure and the cleaning mechanism form a time-space coordination strategy: the grid prevents scale sources during the day and removes trace deposits at night with automatic flushing, constructing a 24-hour full-cycle protection closed loop.

[0039] The implementation principle of this embodiment is as follows: The inclined filter grid 6 inside the feed port 3 filters the large stones entering the hydrocyclone, preventing the hydrocyclone from being blocked and protecting the internal structure of the hydrocyclone. A high-pressure water pump is connected to the water inlet 704. The other end of the high-pressure water pump is connected to an external cleaning liquid storage device. The timer control module 703 controls the operation and stop of the water pump. After the water pump starts working, the high-pressure solenoid valve 702 opens, allowing the cleaning liquid to be sprayed out from the nozzle 706 of the pipe 701 to clean the inside of the hydrocyclone and ensure that the inside of the hydrocyclone is unobstructed.
