Description

Technical Field

[0001] This utility model relates to the field of mineral sorting equipment, specifically a device for adjusting the flow rate of water in the jigging chamber of a jig. Background Technology

[0002] The jig is a long-established and widely used gravity separation equipment. It utilizes the loosening and settling effect caused by the alternating upward and downward pulsed water flow to separate mineral particles into layers according to their density in the jig chamber, ultimately achieving the separation of light and heavy minerals. It plays an important role in coal preparation, roughing and pre-selection of various metallic and non-metallic ores, and some recycling fields, and is especially known for its advantages in processing coarse materials and relatively low cost.

[0003] In existing jigs, the jigging machines can only separate minerals by blowing them with a fixed airflow speed. This single airflow speed can easily lead to inaccurate mineral separation during the separation process. Furthermore, it is impossible to adjust the flow rate of the water in the jigging chamber for more precise mineral separation. Therefore, the inventors urgently need to design a device to adjust the flow rate of the water in the jigging chamber of a jig. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a device for adjusting the flow rate of water in the jigging chamber of a jig, so as to solve the technical problem that the flow rate of water in the jigging chamber of a jig is not adjustable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for regulating the descent speed of a jigging machine's jigging chamber, comprising a body and a jigging chamber. An air chamber is provided at the center of the interior of the body. Vertical air valves are provided on the inner sidewall of the air chamber. The air valves include small air valves, medium air valves, and large air valves arranged coaxially from top to bottom. Each air outlet of the air valves is a downward-facing inclined groove structure. Three vertically arranged air valve switches are installed on the outer sidewall of the body. The air valve switches are connected to the corresponding air valves via connecting rods that penetrate the sidewall of the body. An air vent communicating with the jigging chamber is provided at the top of the air chamber.

[0006] By adopting the above technical solution, the air valves are designed as a three-stage structure with vertically distributed air outlets and a downward-facing inclined groove structure, which enables compressed air to act precisely on the water flow system of the jigging chamber in stages. The small air valves open first to form the initial water flow disturbance, and the medium and large air valves intervene in stages to enhance the downward water flow power. This stepped air supply effectively solves the problem of bed disturbance caused by sudden changes in water flow when the traditional single valve is started and stopped.

[0007] Furthermore, a baffle is installed at the connection between the jigging chamber and the air chamber, and a number of equidistant air holes are opened on the surface of the baffle.

[0008] By adopting the above technical solution, the structure of baffles set between the jigging chamber and the air chamber with equidistant air holes allows compressed air to be effectively dispersed after being ejected from the air vent, forming a uniform air curtain that acts on the water. This distribution method avoids the vortex effect caused by excessive local airflow and ensures stable water flow pulsation.

[0009] Furthermore, a fan box is fixed to the middle of the rear side of the machine body by bolts, and a fan is installed at the bottom of the fan box by bolts, with the air inlet of the fan facing the bottom of the fan box.

[0010] By adopting the above technical solution, the fan box is fixed to the middle of the rear side of the machine body by bolts, which ensures that the vibration transmission path of the fan is perpendicular to the direction of water flow in the jig chamber when the fan is working, effectively avoiding resonance interference with the stability of the bed.

[0011] Furthermore, the fan box has an enclosed chamber inside, the air outlet of the fan extends into the enclosed chamber, and a rubber sealing ring is embedded at the connection between the fan and the enclosed chamber, and the enclosed chamber is connected to the air valve.

[0012] By adopting the above technical solution, the structure of extending the fan outlet into the enclosed chamber allows the airflow to enter the pressure buffer chamber directly without leakage. Combined with the tight installation of the sealing ring at the connection, the gas escape phenomenon in traditional flange connections is completely eliminated, and the air pressure stability is maintained.

[0013] Furthermore, a motor housing is bolted to the lower side of the fan housing, and a drive motor is bolted to the inside of the motor housing. The output end of the drive motor passes through the bottom plate of the fan housing and is connected to the fan.

[0014] By adopting the above technical solution, the structure in which the motor box is independently set on the lower side of the fan box isolates the influence of the heat source of the drive motor on the fan intake temperature and avoids air volume deviation caused by changes in the gas expansion coefficient.

[0015] Furthermore, an adjustment switch is provided on the outer wall of the machine body. The adjustment switch is connected to the fan through a conduit embedded in the inner wall of the machine body and is used to adjust the air volume of the fan.

[0016] By adopting the above technical solution, the adjustment switch is located on the outer wall of the machine body and connected to the fan through the built-in conduit, which allows the operator to adjust the airflow parameters in real time during the jigging operation. The external independent switch layout avoids the risk of short circuit caused by water splashing.

[0017] Furthermore, an air inlet slot is provided on the bottom plate of the fan box, and the air inlet slot is located directly below the air inlet of the fan.

[0018] By adopting the above technical solution, the air inlet slot is opened on the bottom plate of the fan box and faces the air inlet of the fan, forming the shortest path of fresh air supply channel, so that the airflow is input into the fan system with minimal resistance. This vertical through design avoids the sharp bend loss problem of traditional side air intake.

[0019] Furthermore, a dustproof net is installed on the bottom surface of the air inlet slot via a snap fastener, and the surface of the dustproof net is evenly distributed with several mesh holes.

[0020] By adopting the above technical solution, the dustproof net is installed on the bottom of the air inlet slot through a snap-fit ​​structure, which enables quick disassembly and cleaning in a hundred seconds. This solves the problem of excessive time consumption when fixing the filter with traditional bolts. The elastic locking mechanism of the snap-fit ​​also prevents the risk of loosening caused by equipment vibration.

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

[0022] 1. This utility model adopts a three-stage air valve with a longitudinal vertical coaxial layout and an air outlet designed with a downward-facing inclined groove structure, so that compressed air acts on the water in the jigging chamber in stages. This structure avoids sudden changes in water flow by starting the small air valve with low flow, the medium air valve provides transitional pressure supplementation, and the large air valve provides the main air supply to enhance suction force, so as to achieve precise step-by-step control of the descending water flow. At the same time, the air valve switch is rigidly connected to the air valve through the connecting rod that runs through the side wall of the machine body, eliminating the delay of traditional soft transmission and ensuring real-time response to air pressure commands in the air chamber. The direct connection layout between the air outlet and the jigging chamber further shortens the airflow and water pressure transmission path, reducing energy loss and response lag caused by pressure attenuation.

[0023] 2. This utility model uses the oblique air hole structure of the baffle to evenly disperse the airflow impact, avoiding eddy currents from disrupting the stratification process of the jigging chamber. Its layout extending to the feed inlet simultaneously intercepts impurities and protects the air valve. The sealing ring flange connection between the blower and the closed chamber prevents air leakage. Combined with the vertical channel design of the blower box air inlet slot directly facing the air inlet, it ensures zero pressure loss of airflow input. At the same time, the layout of the motor box independent of the bottom of the blower box isolates the drive motor from heat source interference. The output shaft is directly connected to the blower impeller, eliminating belt drive losses. The snap-on installation structure of the dustproof net and the evenly distributed micropores filter coal dust, avoiding wear and instability of the blower impeller. The built-in conduit protection design of the regulating switch prevents dust infiltration and maintains the long-term stability of electrical control commands in humid and dusty environments. The installation methods of bolt fixing or snap-on connection of each component enable quick disassembly and maintenance, solving the maintenance bottleneck of traditional integrated structures.

Detailed Implementation

[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 device for regulating the rate of water flow down the jigging chamber of a jig, such as Figure 1-4 As shown, the system includes a machine body 1 and a jigging chamber 2. An air chamber 8 is located at the center of the machine body 1. Vertical air valves 10 are installed on the inner wall of the air chamber 8. Each air valve 10 includes a small air valve 1001, a medium air valve 1002, and a large air valve 1003 arranged coaxially from top to bottom. Each air outlet of the air valve 10 is a downward-facing inclined groove structure. Three vertically arranged air valve switches 6 are installed on the outer wall of the machine body 1. The air valve switches 6 are connected to the corresponding air valves 10 via connecting rods 16 that penetrate the side wall of the machine body 1. An air outlet 9 connecting to the jigging chamber 2 is located at the top of the air chamber 8. The air valves 10 are designed as a three-stage structure with vertically distributed air outlets and downward-facing inclined grooves, allowing compressed air to... It can precisely act on the water flow system of jigging chamber 2 in stages. The small air valve 1001 opens first to form the initial water flow disturbance, and the medium air valve 1002 and the large air valve 1003 intervene in stages to enhance the downward water flow power. This stepped air supply effectively solves the problem of bed disturbance caused by the sudden change of water flow when the traditional single valve is started and stopped. At the same time, the rigid connection structure of the air valve switch 6 and the connecting rod 16 through the side wall of the machine body 1 ensures that the operation command can be directly transmitted to the air valve 10 inside the air chamber 8, eliminating the transmission lag effect of the traditional soft connection, making the airflow release response of the air outlet 9 more timely. The straight-through layout of the air chamber 8 and the jigging chamber 2 further shortens the air pressure action path and avoids pressure loss affecting the water flow control accuracy.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A baffle 3 is installed at the connection between the jigging chamber 2 and the air chamber 8. Several equidistant air holes are opened on the surface of the baffle 3. The structure of the baffle 3, which is set between the jigging chamber 2 and the air chamber 8 and has equidistant air holes, allows the compressed air to be effectively dispersed after being ejected from the air outlet 9, forming a uniform air curtain that acts on the water. This distribution method avoids the vortex effect caused by excessive local airflow and ensures stable water flow. At the same time, the oblique installation structure of the baffle 3 guides the airflow to impact the water at a specific angle, generating directional downward water flow power, promoting the stratification of materials in the jigging chamber 2 according to density. Its air hole layout can intercept large particles of impurities from entering the air chamber 8, prevent the air valve 10 from being blocked, and significantly reduce the frequency of downtime maintenance.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The fan box 4 is bolted to the middle of the rear side of the machine body 1. The fan 11 is bolted to the bottom of the fan box 4, and the air inlet of the fan 11 faces the bottom of the fan box 4. The structure of the fan box 4 being bolted to the middle of the rear side of the machine body 1 ensures that the vibration transmission path of the fan 11 is perpendicular to the water flow direction of the jig chamber 2 when the fan 11 is working, effectively avoiding resonance interference with the stability of the bed. At the same time, the downward installation layout of the air inlet of the fan 11 is directly aligned with the bottom space of the fan box 4, forming a vertical downward airflow suction path, improving the airflow circulation efficiency and reducing turbulence loss. The bolt connection method facilitates the quick calibration of the coaxiality of the fan 11 during disassembly and maintenance, ensuring the dynamic stability of the equipment during long-term operation.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The blower box 4 has a closed chamber 13 inside, and the air outlet of the blower 11 extends into the closed chamber 13. A rubber sealing ring 12 is embedded at the connection between the blower 11 and the closed chamber 13. The closed chamber 13 is connected to the air valve 10. The structure of the air outlet of the blower 11 extending into the closed chamber 13 allows the airflow to enter the pressure buffer chamber directly without leakage. With the tight embedding of the sealing ring 12 at the connection, the gas escape phenomenon in the traditional flange connection is completely eliminated, and the air pressure stability is maintained. At the same time, the closed chamber 13 acts as a transition chamber to convert the turbulent flow output by the blower 11 into laminar flow before sending it into the air valve 10, eliminating the interference of airflow pulsation on the jet frequency of the air outlet 9, and finally making the water flow descent process curve of the jigging chamber 2 smoother and more controllable.

[0035] See Figure 1 , Figure 3 , Figure 4The fan housing 4 is bolted to the lower side of the motor housing 7. The motor housing 7 is bolted to the inside of the motor housing 7. The output end of the motor 14 passes through the bottom plate of the fan housing 4 and is connected to the fan 11. The motor housing 7 is independently set on the lower side of the fan housing 4, which isolates the heat source of the motor 14 from the influence of the air intake temperature of the fan 11 and avoids the air volume deviation caused by the change of the gas expansion coefficient. At the same time, the installation method of the output shaft of the motor 14 passing through the bottom plate of the fan housing 4 and directly connecting to the impeller of the fan 11 completely eliminates the tensioning mechanism required by the belt drive, reduces energy loss in the intermediate links, and makes the speed command response of the fan 11 zero delay. The bolt fixing structure ensures that the motor output center is permanently coaxial with the fan impeller and avoids vibration accumulation that damages the bearings.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An adjustment switch 5 is installed on the outer wall of the body 1. The adjustment switch 5 is connected to the fan 11 through a conduit embedded in the inner wall of the body 1. It is used to adjust the air volume of the fan 11. The adjustment switch 5 is located on the outer wall of the body 1 and connected to the fan 11 through the built-in conduit, so that the operator can adjust the airflow parameters in real time during the jigging operation. The external independent switch layout avoids the risk of short circuit caused by water splash. At the same time, the design of the conduit protects the connection line from dust wear and mechanical collision, completely eliminating the electrical fault caused by coal dust accumulation in traditional exposed cables, significantly improving the reliability of electrical control and extending the life of components.

[0037] See Figure 1 , Figure 3 , Figure 4 An air inlet slot 17 is provided on the bottom plate of the fan box 4. The air inlet slot 17 is located directly below the air inlet of the fan 11. The structure of the air inlet slot 17 on the bottom plate of the fan box 4 and facing the air inlet of the fan 11 forms the shortest path fresh air supply channel, so that the airflow enters the fan system with minimal resistance. This vertical through design avoids the sharp bend loss problem of traditional side air intake. At the same time, the slot design forms a negative pressure amplification effect, which enhances the adsorption efficiency of the ambient airflow, ensuring that the fan 11 can still maintain the rated air volume supply under high load conditions, and ensuring the continuous and stable water flow driving air pressure required by the jigging chamber 2.

[0038] See Figure 4The bottom surface of the air inlet slot 17 is fitted with a dustproof net 15 via clips. The dustproof net 15 has several mesh holes evenly distributed on its surface. The structure of the dustproof net 15 being installed on the bottom surface of the air inlet slot 17 via clips enables quick disassembly and cleaning in a hundred seconds, solving the problem of excessive time consumption when using traditional bolt-fixed filters. The elastic locking mechanism of the clips also prevents the risk of loosening caused by equipment vibration. At the same time, the micropores evenly distributed on the mesh surface can intercept coal dust from entering the fan 11, avoiding noise and efficiency reduction caused by blade wear imbalance, ensuring the airflow channel remains unobstructed for a long time. The sealing lip structure at its edge further eliminates the bypass leakage of unfiltered air.

[0039] The implementation principle of this embodiment is as follows: Compressed air is pressurized by the blower 11 and enters the closed chamber 13. Under the sealing effect of the sealing ring 12, the air pressure is kept stable. The closed chamber 13 converts the turbulent flow into laminar flow and then inputs it into the longitudinally arranged air valves 10. The operator activates the three-stage air valves in sequence through the air valve switch 6: the small air valve 1001 opens first, injecting the initial low-pressure airflow into the air chamber 8 from the downward-facing inclined groove; the medium air valve 1002 then intervenes to supplement the air pressure; finally, the large air valve 1003 releases the main airflow to form a high-pressure airflow. The airflow is sprayed into the jigging chamber 2 through the air outlet 9 at the top of the air chamber 8. Along the way, it is dispersed by the inclined air holes of the baffle 3 to form a uniform air curtain. The impact water body drives the water flow to pulsate. Under the guidance of the screen plate, the impact water flow forms a downward water flow force, causing the materials in the jigging chamber 2 to stratify according to density: high-density minerals pass through the screen plate and settle, while light minerals float out with the rising water flow. The air intake of the blower 11 directly draws in fresh air from the outside through the air intake slot 17 at the bottom of the blower box 4. The dust filter 15 filters dust to maintain the purity of the airflow. The drive motor 14 is placed in an independent motor box 7 and directly drives the blower impeller through the structure that runs through the bottom plate, ensuring zero power loss transmission. The layout of the whole machine, with the baffle 3 extending to the feed inlet, intercepts impurities. Combined with the modular installation structure of bolts and clips, it achieves smooth air passage and rapid maintenance in synergistic operation.
