Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of coal preparation equipment technology, and more specifically, to a jig with a stable pulsating water flow. Background Technology
[0002] In many industrial fields such as mineral processing and coal separation, jigs are an important sorting device. Their working principle is based on the separation of materials of different densities into strata according to density under the action of pulsating water flow. Stable and uniform pulsating water flow plays a decisive role in the efficient and accurate sorting of jigs.
[0003] However, existing jigs face the technical challenge of uneven bed pulsation during actual operation. This is mainly due to defects in the pulsation water flow generation mechanism of traditional jigs. For example, their drive devices struggle to ensure stable water flow output when generating pulsation, leading to irregular fluctuations in the water flow within the jig bed. This uneven pulsation results in suboptimal material stratification within the bed, with some materials failing to separate effectively according to the expected density differences, thus severely impacting the jig's sorting accuracy and production efficiency. Furthermore, uneven pulsation can exacerbate wear on internal components, increasing maintenance costs and downtime, thus hindering the economic benefits and sustainable development of related industries. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a jig with a stable pulsating water flow, which solves the technical problem of uneven pulsation of the jig bed in the prior art.
[0005] According to one aspect, at least one embodiment of the present disclosure provides a jig with a stable pulsating water flow, comprising:
[0006] The machine body has a partition plate arranged vertically along its length inside, which divides the machine body into a jigging chamber and an air chamber. The bottom sides of the jigging chamber and the air chamber are connected. The side wall of the machine body has an air inlet, which is connected to the air chamber.
[0007] A flow stabilizer plate is disposed in the air chamber. The flow stabilizer plate is arranged to float on the liquid surface and slide vertically in the air chamber when the liquid pulsates in the air chamber. This is to prevent the liquid from generating jigging waves in the air chamber, so as to avoid the jigging waves affecting the uniformity of the jigging chamber bed during air intake, and also to prevent liquid from splashing into the air inlet during exhaust and forming water in the exhaust.
[0008] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, the air chamber is further provided with a guide rail for guiding the flow stabilizer plate to slide vertically, and the two ends of the guide rail are respectively connected to the top wall and the bottom wall of the air chamber.
[0009] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, the air chamber is further provided with a rope for pulling the flow stabilizer plate, the two ends of the rope being connected to the flow stabilizer plate and the inner wall of the air chamber respectively, to prevent the flow stabilizer plate from flipping in the air chamber.
[0010] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, the air chamber is further provided with an air distribution pipe arranged along the length direction of the air chamber. One end of the air distribution pipe is connected to the air inlet. The air distribution pipe has an air distribution groove opened along the length direction. Air enters the air distribution pipe through the air inlet and enters the air chamber from the air distribution groove.
[0011] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, the air distribution trough faces the top of the air chamber.
[0012] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, there are several ropes, and the several ropes are evenly spaced along the circumference of the flow stabilizer.
[0013] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, the rope is elastic.
[0014] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, there are several guide rails, and the several guide rails are evenly spaced along the length direction of the air chamber.
[0015] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, the jig with a stable pulsating water flow further includes a sieve plate disposed in the machine body for sealing the jig chamber.
[0016] For example, in a jig with a stable pulsating water flow provided in at least one embodiment of this disclosure, the partition plate is configured to have a vertical section and an inclined section, with an angle between the vertical section and the inclined section, the inclined section being located above the vertical section, and the side of the inclined section away from the vertical section being connected to the inner wall of the machine body near the air chamber.
[0017] The beneficial effects of the embodiments disclosed herein are as follows:
[0018] In this disclosure, the jig effectively solves the problems of unstable bed and liquid splashing into the air inlet in traditional jigs by installing a flow stabilizer in the air chamber. By resolving the bed instability and preventing liquid from entering the air inlet, the unobstructed airflow is ensured, allowing air to enter the air chamber stably and thus guaranteeing the stability of pressure changes within the air chamber. This stable pressure change makes the pulsating water flow in the jig chamber and air chamber more stable and regular.
[0019] A stable, pulsating water flow also facilitates the stratification of materials according to density within the jigging chamber. Under the influence of a stable, pulsating water flow, materials of different densities can be more accurately distributed in the jigging chamber bed according to their density differences, improving the material sorting effect. Simultaneously, stable operation reduces equipment malfunctions caused by liquid splashing and unstable pulsation, lowering maintenance costs and downtime, and increasing equipment lifespan and production efficiency.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0030] like Figure 1The diagram illustrates a jig with a stable pulsating water flow according to an embodiment of this disclosure. A vertical partition 2 is provided inside the machine body 1, dividing the internal space of the machine body 1 into a jigging chamber 11 and an air chamber 12. The jigging chamber 11 and the air chamber 12 are interconnected at the bottom, allowing the liquid inside both chambers to flow between them. An air inlet 13 is provided on the side wall of the machine body 1, communicating with the air chamber 12. Its function is to introduce air into the air chamber 12 to change the pressure within it.
[0031] When external air enters the air chamber 12 through the air inlet 13, the pressure inside the air chamber 12 changes. Since the jigging chamber 11 and the air chamber 12 are connected at the bottom, the pressure change in the air chamber 12 causes liquid to flow between the two chambers, thus forming a pulsating water flow. However, the pressure change in the air chamber 12 may cause the liquid to fluctuate violently, forming jigging waves. To solve this problem, a flow stabilizer 3 is installed inside the air chamber 12. The flow stabilizer 3 is a floating material and is placed on the liquid surface inside the air chamber 12. When the liquid pulsates, it slides vertically within the air chamber 12 along with the liquid surface. The presence of the flow stabilizer 3 increases the damping of the liquid surface, reduces the amplitude of liquid surface vibration, and thus suppresses the generation of jigging waves. The mass and buoyancy of the flow stabilizer 3 enable it to resist the fluctuations of the liquid surface, converting the energy of the liquid fluctuations into its own potential and kinetic energy, thereby preventing the liquid from generating excessive jigging waves and preventing liquid from splashing into the air inlet 13.
[0032] During this process, the flow stabilizer 3 on the liquid surface inside the air chamber 12 slides vertically within the air chamber 12 as the liquid rises and falls. When the liquid tends to generate jigging waves, the flow stabilizer 3 suppresses the formation of jigging waves through its own vertical sliding and pressure on the liquid surface. If there are local protrusions on the liquid surface forming the initial shape of jigging waves, the flow stabilizer 3 will exert downward pressure on the protruding parts under the action of buoyancy and gravity, causing the liquid to return to stability and preventing the liquid from splashing into the air inlet 13 due to excessive jigging waves.
[0033] The advantage lies in the fact that this jig effectively solves the problem of liquid splashing into the air inlet 13 in traditional jigs by installing a flow stabilizer 3 inside the air chamber 12. By preventing liquid from entering the air inlet 13 and ensuring its unobstructed flow, air can stably enter the air chamber 12, thereby ensuring the stability of pressure changes within the air chamber 12. Stable pressure changes make the pulsating water flow in the jig chamber 11 and the air chamber 12 more stable and regular.
[0034] A stable pulsating water flow facilitates the stratification of materials according to density within the jigging chamber 11. Under the influence of this stable pulsating water flow, materials of different densities can be more accurately distributed within the bed of the jigging chamber 11 according to their density differences, improving the material sorting effect. Simultaneously, the stable operating state reduces equipment malfunctions caused by liquid splashing and unstable pulsation, lowering maintenance costs and downtime, and increasing equipment lifespan and production efficiency.
[0035] like Figure 1 As shown, a guide rail 4 is added inside the air chamber 12. The two ends of the guide rail 4 are connected to the top and bottom walls of the air chamber 12, respectively, forming a stable guiding structure. Under the action of liquid pulsation within the air chamber 12, the flow stabilizer 3 slides vertically along the liquid surface. The presence of the guide rail 4 provides a clear path for the sliding of the flow stabilizer 3, preventing it from shifting or wobbling during the sliding process, thus better fulfilling its function of preventing jigging waves in the liquid.
[0036] Specifically, when the liquid in the air chamber 12 pulsates due to pressure changes, the flow stabilizer 3 begins to slide vertically. During this sliding process, the flow stabilizer 3 contacts the guide rail 4, which guides the flow stabilizer 3. Regardless of the pulsation of the liquid, the flow stabilizer 3 will move along the path specified by the guide rail 4. For example, when the pressure in the air chamber 12 increases and the liquid in the jigging chamber 11 rises, the flow stabilizer 3 slides upward along the guide rail 4 under the action of buoyancy; when the pressure in the air chamber 12 decreases and the liquid falls, the flow stabilizer 3 slides downward along the guide rail 4 under the action of gravity.
[0037] The advantage is that the guide rail 4 makes the vertical sliding of the flow stabilizer 3 more stable and reliable. Stable sliding ensures that the flow stabilizer 3 always maintains good contact with the liquid surface, thereby more effectively suppressing jigging waves on the liquid surface. In addition, the guide rail 4 can also prevent the flow stabilizer 3 from colliding or rubbing against the inner wall of the air chamber 12 during sliding, reducing the wear of the flow stabilizer 3, extending its service life, and further improving the stability and reliability of the jig.
[0038] like Figure 2 As shown, a rope 5 is installed inside the air chamber 12, with its two ends connected to the flow stabilizer 3 and the inner wall of the air chamber 12, respectively. The function of the rope 5 is to prevent the flow stabilizer 3 from overturning inside the air chamber 12. When the liquid in the air chamber 12 pulsates, the flow stabilizer 3 is subjected to various forces, such as the impact force of the liquid and the uneven distribution of buoyancy, which may cause the flow stabilizer 3 to overturn. The rope 5 restricts the rotational freedom of the flow stabilizer 3 by applying tension to it.
[0039] Specifically, during the jig's operation, the liquid in the air chamber 12 continuously pulsates, causing the flow stabilizer 3 to slide up and down. Throughout this process, the rope 5 consistently applies tension to the flow stabilizer 3. When the liquid pulsation causes the flow stabilizer 3 to tend to tilt, the rope 5 automatically adjusts the magnitude and direction of the tension based on the position and force applied to the flow stabilizer 3 to maintain its balance. For example, if one side of the flow stabilizer 3 experiences a large liquid impact and tends to tilt upwards, the rope 5 applies a greater tension to the opposite side, pulling the flow stabilizer 3 back to its equilibrium position.
[0040] The advantage is that the rope 5 effectively prevents the flow stabilizer 3 from flipping inside the air chamber 12. If the flow stabilizer 3 flips, it will not be able to properly prevent the liquid from generating jigging waves, and may even affect the normal flow of the liquid inside the air chamber 12. By preventing the flow stabilizer 3 from flipping, the rope 5 ensures that the flow stabilizer 3 can always float stably on the liquid surface, improving the working efficiency and stability of the jig.
[0041] like Figures 1-2 As shown, an air distribution duct 6 is added inside the air chamber 12. The air distribution duct 6 is laid along the length of the air chamber 12, and one end of it is connected to the air inlet 13. An air distribution groove 61 is formed along the length of the air distribution duct 6. After air enters the air distribution duct 6 through the air inlet 13, it enters the air chamber 12 through the air distribution groove 61. The arrangement of the air distribution duct 6 and the air distribution groove 61 ensures that the air entering the air chamber 12 is evenly distributed. Traditional air intake methods may cause localized air concentration within the air chamber 12, resulting in uneven pressure distribution and affecting the pulsation effect of the liquid. The air distribution duct 6 guides the air to various parts of the air chamber 12, while the air distribution groove 61 allows the air to be evenly discharged from the air distribution duct 6, making the pressure distribution within the air chamber 12 more uniform.
[0042] The advantages are that the arrangement of the air distribution duct 6 and the air distribution channel 61 makes the pressure distribution within the air chamber 12 more uniform, thereby making the liquid pulsation more stable. Stable pulsating water flow facilitates better stratification of materials according to density within the jigging chamber 11, improving the sorting accuracy of the jig. Furthermore, uniform pressure distribution reduces the occurrence of excessively high or low local pressures within the air chamber 12, lowering the risk of damage caused by uneven pressure and extending the equipment's service life.
[0043] like Figures 1-2 As shown, the air distribution trough 61 faces the top of the air chamber 12. When air enters the air chamber 12 from the air distribution trough 61, because the air distribution trough 61 faces the top of the air chamber 12, the air will flow upward, first acting on the top wall of the air chamber 12, and then blowing in the opposite direction towards the surface of the liquid. This allows the air to diffuse more widely, making full contact with the liquid surface and more effectively driving the liquid to pulsate.
[0044] The advantage is that the air distribution trough 61 faces the top of the air chamber 12, allowing air to first blow towards the top of the air chamber 12 and then towards the liquid surface. This expands the gas diffusion area and allows the gas to act more effectively on the liquid surface, improving the liquid pulsation effect. Better liquid pulsation enables the material in the jigging chamber 11 to more accurately stratify according to density under the action of pulsating water flow, thereby improving the sorting efficiency and accuracy of the jig. In addition, the upward-facing opening of the air distribution trough 61 also prevents sporadic splashes of liquid from entering the air distribution trough 61.
[0045] like Figure 2 As shown, there are several ropes 5, evenly spaced along the circumference of the flow stabilizer 3. The even distribution of multiple ropes 5 around the circumference of the flow stabilizer 3 ensures that the flow stabilizer 3 is subjected to uniform tension in all directions. When the flow stabilizer 3 is subjected to the impact force of the liquid or other external forces, the multiple ropes 5 work together to evenly distribute the external force to various parts of the flow stabilizer 3, thereby better maintaining the balance of the flow stabilizer 3 and preventing it from overturning or tilting.
[0046] The advantage is that the ropes 5 are evenly spaced around the circumference of the flow stabilizer 3, which improves the constraint effect on the flow stabilizer 3. The uniform tension distribution significantly improves the stability of the flow stabilizer 3 in the air chamber 12, better preventing the flow stabilizer 3 from flipping over, ensuring that it can always float stably on the liquid surface, effectively suppressing jigging waves on the liquid surface, and improving the working stability and reliability of the jig.
[0047] like Figure 2 As shown, rope 5 is elastic, a property that allows it to deform elastically when subjected to external forces. When the liquid in the air chamber 12 pulsates, the flow stabilizer 3 slides up and down with the rise and fall of the liquid, and may also be subjected to external forces such as liquid impact. The elastic rope 5 can extend and retract under these external forces, thus better adapting to the movement and force changes of the flow stabilizer 3.
[0048] Specifically, during the operation of the jig, when the pulsation of the liquid causes the flow stabilizer plate 3 to rise or fall rapidly, the elastic rope 5 will extend or contract according to the speed and direction of the flow stabilizer plate 3. For example, when the flow stabilizer plate 3 rises rapidly, the rope 5 will be stretched to absorb some of the kinetic energy of the flow stabilizer plate 3; when the flow stabilizer plate 3 falls, the rope 5 will contract to release the stored elastic potential energy, helping the flow stabilizer plate 3 to fall smoothly. At the same time, when the impact force of the liquid acts on the flow stabilizer plate 3, the elastic rope 5 will buffer the impact force through extension and contraction, making the force on the flow stabilizer plate 3 more stable.
[0049] like Figure 1As shown, there are several guide rails 4, which are evenly spaced along the length of the air chamber 12. The arrangement of multiple guide rails 4 can provide more stable guidance for the flow stabilizer 3. Each guide rail 4 can constrain the sliding of the flow stabilizer 3 to a certain extent. The combined action of multiple guide rails 4 can more precisely restrict the horizontal movement of the flow stabilizer 3, so that the flow stabilizer 3 can only slide vertically along the direction of the guide rail 4.
[0050] The advantage lies in the fact that the multiple guide rails 4 are evenly spaced along the length of the air chamber 12, which improves the stability and accuracy of the vertical sliding of the flow stabilizer 3. Stable sliding allows the flow stabilizer 3 to better prevent the liquid from generating jigging waves, while also reducing wear between the flow stabilizer 3 and the guide rails 4, extending the service life of the equipment. Furthermore, the arrangement of multiple guide rails 4 enhances the stability of the internal structure of the air chamber 12, improving the overall reliability of the jig.
[0051] like Figures 1-2 As shown, the jig also includes a sieve plate 7, which is installed inside the machine body 1 to support the sorted minerals.
[0052] Specifically, during jig operation, the sieve plate 7 always covers the jig chamber 11. When pressure changes within the air chamber 12 cause liquid to flow between the jig chamber 11 and the air chamber 12, forming a pulsating water flow, the liquid and materials within the jig chamber 11 move with the pulsating water flow. Due to the presence of the sieve plate 7, even if the liquid and materials tend to splash, they will be blocked by the sieve plate 7 and will not splash out of the machine body 1. For example, when the water level in the jig chamber 11 rises, the liquid may generate a certain impact force, causing some liquid and materials to splash upwards, but the sieve plate 7 will block it within the jig chamber 11 to support the sorting of minerals.
[0053] like Figures 1-2 As shown, the partition plate 2 has a vertical section 21 and an inclined section 22, with an angle between them. The inclined section 22 is located above the vertical section 21, and the side of the inclined section 22 away from the vertical section 21 is connected to the inner wall of the machine body 1 near the air chamber 12. The presence of the inclined section 22 can optimize the liquid flow between the jigging chamber 11 and the air chamber 12. The inclined section 22 can also reduce the resistance of the liquid during the flow process, making the liquid pulsation more stable.
[0054] Specifically, when air enters the air chamber 12 through the air inlet 13, the pressure inside the air chamber 12 increases, and the liquid inside the air chamber 12 begins to flow towards the jigging chamber 11. The liquid first comes into contact with the inclined section 22 of the partition plate 2, which guides the liquid into the jigging chamber 11, allowing the liquid to enter the jigging chamber 11 more evenly. When the air in the air chamber 12 is discharged and the pressure decreases, the liquid in the jigging chamber 11 flows back to the air chamber 12, and the inclined section 22 again plays a guiding role, allowing the liquid to flow back smoothly into the air chamber 12. In this process, the presence of the inclined section 22 makes the liquid flow smoother and reduces energy loss during the liquid flow process.
[0055] The advantage is that the partition plate 2 optimizes the liquid flow between the jigging chamber 11 and the air chamber 12, making the liquid pulsation more stable and uniform. Furthermore, the space formed by the vertical section 21 and the sidewall provides suitable sliding space for the flow stabilizer plate 3, and the stable liquid pulsation facilitates better density stratification of materials within the jigging chamber 11, improving the sorting accuracy and efficiency of the jig.
