Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of hydrocyclone structure technology, and more specifically to a special hydrocyclone structure for mud separation. Background Technology
[0002] In today's industrial production and various engineering construction fields, mud treatment is a crucial and ubiquitous problem. From mining and oil drilling to construction and river dredging, industries generate large quantities of complex mud. This mud is typically a mixture of water, clay, rock particles, and various chemical additives. If not properly treated, it can not only cause serious environmental pollution but also affect the continuity and efficiency of production.
[0003] Taking mining as an example, the extraction and washing of ore generates a large amount of drilling mud rich in mineral particles. If this mud is discharged directly, the heavy metal ions and harmful substances within it will seep into the soil and groundwater, disrupting the ecological balance. Furthermore, untreated mud can clog drainage pipes, affecting subsequent mining operations. Similarly, in oil drilling operations, drilling mud is used for critical processes such as cooling the drill bit, carrying cuttings, and balancing formation pressure. With increasing drilling depth and scale, the amount of drilling mud generated is also considerable. If the mud cannot be effectively separated and treated, it will not only waste resources but may also affect the safety and efficiency of drilling operations due to the deterioration of mud properties.
[0004] Traditional mud separation methods face numerous challenges. Natural sedimentation is inefficient, requires significant space, and is ineffective at separating fine particles. While filtration offers some precision, the equipment is prone to clogging, resulting in high maintenance costs and limited efficiency when handling high-concentration, high-viscosity mud. Although conventional hydrocyclones utilize centrifugal force for solid-liquid separation, their internal structure lacks specificity for separating particles of different sizes, and their poor wear resistance leads to severe wear on key components when processing mud containing hard particles, shortening equipment lifespan and increasing operating costs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 In this embodiment of the present invention, a special hydrocyclone structure for mud separation includes a mud hydrocyclone 1, and a discharge control device 2 is installed at the bottom of the mud hydrocyclone 1.
[0029] The mud hydrocyclone 1 includes a feed inlet 11, one end of which is connected to a mud conveying pump, and the other end is fixedly connected to an upper cylinder 12. The upper end of the upper cylinder 12 is fixedly connected to a light phase overflow port 13. An intermediate phase overflow port 14 is provided at the middle position of the inner side of the light phase overflow port 13. The bottom of the light phase overflow port 13 and the intermediate phase overflow port 14 are connected to the cavity inside the upper cylinder 12.
[0030] By adopting the above technical solution, the double overflow port of the upper cylinder 12 enables the graded separation of particles of different sizes in the slurry. The light phase overflow port 13 mainly discharges the clean liquid after sufficient separation; the intermediate phase overflow port 14 collects the liquid containing a small amount of fine particles. These liquids can be selected to be returned to the feed end for secondary separation or transported to a specific processing stage according to actual production needs, so as to maximize the utilization of resources.
[0031] In this embodiment, the bottom of the upper cylinder 12 is fixedly connected to the middle cylinder 15. The middle cylinder 15 is tapered, and its bottom is fixedly connected to the lower cylinder 16 by multiple fixing bolts.
[0032] The lower cylinder 16 is also tapered, and the taper of the middle cylinder 15 and the lower cylinder 16 decreases sequentially; the inner sides of the upper cylinder 12, the middle cylinder 15 and the lower cylinder 16 are provided with spiral-shaped turbulence rails 19.
[0033] By adopting the above technical solution, the spiral-shaped turbulence track 19 on the inner side of the upper cylinder 12, middle cylinder 15 and lower cylinder 16 enhances the collision and friction between particles, promotes the agglomeration of fine particles, makes the separation process more efficient, and improves the overall separation accuracy; the ceramic-based wear-resistant lining laid on the inner side of the upper cylinder 12, middle cylinder 15 and lower cylinder 16 has high hardness and strong wear resistance, which greatly reduces the wear of mud on the inside of the cylinder, significantly extends the service life of the equipment, and reduces the maintenance cost and replacement frequency of the equipment;
[0034] The upper cylinder 12, middle cylinder 15, and lower cylinder 16 all adopt a structural design with different tapers. After the mud enters the upper cylinder 12, most of the coarse particles are quickly separated by the larger centrifugal force field of the upper cylinder 12. As the mud flows into the middle cylinder 15 and lower cylinder 16, the diameter gradually decreases and the centrifugal force continuously increases. The middle cylinder 15 is responsible for separating medium-sized particles, while the lower cylinder 16 focuses on capturing fine particles, thus achieving fine classification and separation of the mud.
[0035] In this embodiment, a mounting base 17 is provided on the outer side of the lower cylinder 16, and the mounting base 17 is fixedly connected to the micro vibrator 18 by fixing bolts.
[0036] The bottom of the lower cylinder 16 is fixedly connected to the underflow control valve 21 by multiple fixing bolts. The bottom of the underflow control valve 21 is fixedly connected to the conical discharge port 22 by multiple fixing bolts. The inner side of the conical discharge port 22 is provided with spiral guide vanes 23.
[0037] By adopting the above technical solutions, during discharge, the underflow control valve 21 can accurately control the underflow discharge, the micro-vibrator 18 effectively prevents particle agglomeration and blockage of the underflow port, and the guide vanes 23 of the conical discharge port 22 optimize the underflow discharge path. Together, they ensure the smooth and stable underflow discharge, guarantee the continuous and stable operation of the equipment, and improve production efficiency.
[0038] The working principle of this utility model is as follows: Under the action of the mud conveying pump, the mud obtains sufficient pressure and flow rate and enters the upper cylinder 12 from the feed port 11. Due to its own high-speed flow and the constraint of the internal space of the upper cylinder, a swirling flow begins to form. Under the action of centrifugal force, the denser particles gradually move towards the cylinder wall, while the lighter liquid and some fine particles form an internal swirling flow and flow upward. The liquid with a higher degree of cleanliness is discharged from the light phase overflow port 13, while the liquid containing a small amount of fine particles is discharged from the intermediate phase overflow port 14.
[0039] The double overflow port of the upper cylinder 12 enables the graded separation of particles of different sizes in the mud. The light phase overflow port 13 mainly discharges the clean liquid after thorough separation; the intermediate phase overflow port 14 collects the liquid containing a small amount of fine particles. These liquids can be returned to the feed end for secondary separation or transported to a specific processing stage according to actual production needs, so as to maximize the utilization of resources.
[0040] As the mud flows downwards, it enters the middle cylinder 15, which is conical in shape and connected to the lower cylinder 16 at the bottom by multiple fixing bolts. The taper of the middle cylinder 15 and the lower cylinder 16 decreases sequentially. This design continuously enhances the centrifugal force as the mud flows downwards, further separating medium-sized and finer particles in this area. Simultaneously, the spiral-shaped turbulence rails 19 inside the upper cylinder 12, middle cylinder 15, and lower cylinder 16 disrupt the original flow pattern of the mud, enhance the collision and friction between particles, and promote the aggregation of fine particles into larger particles, making them easier to separate. In addition, the ceramic-based wear-resistant linings laid inside the cylinders not only improve the wear resistance of the equipment, but their surface properties also have a certain influence on the flow pattern of the mud, which helps the separation process.
[0041] The spiral-shaped turbulence rails 19 on the inner sides of the upper cylinder 12, middle cylinder 15, and lower cylinder 16 enhance the collision and friction between particles, promote the agglomeration of fine particles, make the separation process more efficient, and improve the overall separation accuracy. The ceramic-based wear-resistant linings on the inner sides of the upper cylinder 12, middle cylinder 15, and lower cylinder 16 have high hardness and strong wear resistance, which greatly reduces the wear of mud on the inside of the cylinder, significantly extends the service life of the equipment, and reduces the maintenance cost and replacement frequency of the equipment.
[0042] After thorough separation, the solid particles that settle to the bottom of the lower cylinder 16 move towards the underflow control valve 21 under the combined action of gravity and centrifugal force. The bottom of the lower cylinder 16 is fixedly connected to the underflow control valve 21 by multiple fixing bolts. The underflow control valve can control the discharge speed and flow rate of the underflow according to the actual situation. The outer side of the lower cylinder 16 is fixedly connected to the micro-vibrator 18. The high-frequency low-amplitude vibration generated by the micro-vibrator 18 can break up any agglomerates that may form at the bottom of the particles, promoting smooth discharge of the underflow. Finally, after passing through the underflow control valve 21, the underflow is discharged from the conical discharge port 22 at the bottom. The inner side of the conical discharge port 22 has spiral-shaped guide vanes 23, which guide the underflow to be discharged smoothly in a spiral shape, avoiding turbulence interference and ensuring the stability of the underflow discharge.
[0043] During discharge, the underflow control valve 21 can precisely control the underflow discharge, the micro-vibrator 18 effectively prevents particle agglomeration and blockage of the underflow port, and the guide vanes 23 of the conical discharge port 22 optimize the underflow discharge path. Together, they ensure the smooth and stable underflow discharge, guarantee the continuous and stable operation of the equipment, and improve production efficiency.
[0044] The upper cylinder 12, middle cylinder 15, and lower cylinder 16 all adopt a structural design with different tapers. After the mud enters the upper cylinder 12, most of the coarse particles are quickly separated by the larger centrifugal force field of the upper cylinder 12. As the mud flows into the middle cylinder 15 and lower cylinder 16, the diameter gradually decreases and the centrifugal force continuously increases. The middle cylinder 15 is responsible for separating medium-sized particles, while the lower cylinder 16 focuses on capturing fine particles, thus achieving fine classification and separation of the mud.
