Description

Technical Field

[0001] This application relates to the field of dust removal equipment technology, specifically to a dust collector ash removal device for molybdenum mines. Background Technology

[0002] In the process of molybdenum ore beneficiation, a large amount of molybdenum-containing dust is generated in the crushing, screening, grinding and flotation stages. In order to meet the environmental protection emission requirements, sintered plate dust collectors are usually used to collect and treat the molybdenum-containing dust. The sintered plate dust collector is equipped with multiple ash hoppers arranged in sequence. After the molybdenum-containing dust is intercepted by the sintered plate, it is cleaned by pulse jet cleaning and falls into the corresponding ash hopper below, and then discharged through the ash discharge device.

[0003] In existing technologies, the main method for discharging ash from the dust collector's ash hopper is using a screw conveyor. The screw conveyor pushes the dust along the trough to the discharge port through rotating screw blades, and then it is transferred to a centralized collection device. However, screw conveyors have the following shortcomings when handling molybdenum-containing dust:

[0004] Firstly, molybdenum-containing dust has high hardness and adhesiveness, and dust can easily get stuck in the gap between the spiral blades and the trough, leading to increased blade wear or even jamming, resulting in a high failure rate.

[0005] Secondly, screw conveyors are mechanical conveying methods, requiring regular lubrication and maintenance, making it difficult to achieve fully automated operation. The ash removal process still requires manual collection and transfer.

[0006] Third, when multiple ash hoppers share a single screw conveyor, the entire machine needs to be started to operate when any ash hopper discharges ash, resulting in high energy consumption.

[0007] In addition, some existing technologies use hydraulic flushing to remove ash, which uses water flow to flush and transport the dust discharged from the ash hopper. However, this method of ash removal not only fails to achieve sufficient mixing of flushing water and molybdenum-containing dust, but also makes it difficult to maintain a constant ash-to-water ratio. As a result, the slurry concentration entering the subsequent flotation process fluctuates greatly, affecting the flotation indicators.

[0008] In summary, there is an urgent need for a dust removal device for molybdenum mines that can overcome the above-mentioned shortcomings. Utility Model Content

[0009] In order to overcome the shortcomings of the prior art, this utility model discloses a dust collector ash discharge device for molybdenum mines. This utility model can not only discharge molybdenum-containing dust by flushing water in a proportional and quantitative manner to ensure a constant ash-to-water ratio, but also efficiently stir and mix molybdenum-containing dust and water.

[0010] To achieve the above objectives, this application provides the following technical solution:

[0011] A dust collector ash removal device for molybdenum mines includes a sintered plate dust collector, which contains multiple ash storage hoppers arranged in sequence. A discharge pipe is located below each ash storage hopper, and a gate valve and a rotary valve are sequentially installed on the discharge pipe from top to bottom. The device also includes:

[0012] A quantitative feeding mechanism is installed on the ash hopper and linked with the rotary valve to intermittently discharge molybdenum-containing dust from the ash hopper according to a preset ash amount.

[0013] A flushing pipe is installed below the ash hopper to receive molybdenum-containing dust discharged from multiple ash hoppers;

[0014] An electrically controlled valve is installed at one end of the flushing pipe and is linked with the quantitative feeding mechanism. It is used to open synchronously when the quantitative feeding mechanism discharges ash and discharges flushing water quantitatively according to a preset time, so that the molybdenum-containing dust is flushed and transported along the flushing pipe.

[0015] The sludge collection tank is located at the other end of the flushing pipe. A sludge outlet is provided on one side of the sludge collection tank to receive the mixture of molybdenum dust and water and transport it to the flotation workshop.

[0016] The mixing mechanism, located in the sludge collection tank, is used for secondary mixing of molybdenum-containing dust and water.

[0017] Furthermore, the quantitative feeding mechanism includes:

[0018] The upper level gauge is installed on the upper side wall of the ash hopper to detect high material levels and trigger material discharge.

[0019] The lower level gauge is installed on the lower part of the side wall of the ash hopper to detect low material level and stop feeding.

[0020] A pneumatic vibrator is installed on the outer wall of the ash hopper to vibrate the ash hopper and prevent molybdenum-containing dust from bridging.

[0021] The solenoid valve is installed on the pipeline of the pneumatic vibrator and is interlocked with the upper and lower level gauges to control the start and stop of the pneumatic vibrator.

[0022] Furthermore, the stirring mechanism includes:

[0023] The motor is located at the top of the sludge collection tank;

[0024] The mounting rod is horizontally positioned at the upper part of the inner cavity of the sludge collection tank and connected to the motor output end, and is driven to rotate by the motor.

[0025] Multiple stirring rods are erected at the bottom of the mounting rod and spaced apart along the axial direction of the mounting rod, used to stir the mixture of molybdenum dust and water as the mounting rod rotates.

[0026] Furthermore, the stirring mechanism also includes:

[0027] Multiple auxiliary rods are erected on the bottom surface of the sludge collection tank and spaced apart along the axial direction of the mounting rods;

[0028] The stirring rod and the auxiliary rod are arranged alternately in the horizontal direction. The gap between adjacent auxiliary rods is located on the rotation trajectory of the stirring rod. The stirring rod and the auxiliary rod cooperate to form a shear gap for the ash clumps in the mixture of molybdenum dust and water.

[0029] Furthermore, the flushing pipe is provided with multiple installation ports spaced apart along its axial direction, and a turbulence-disrupting component for mixing molybdenum-containing dust and water in the flushing pipe is detachably installed in the installation port.

[0030] Furthermore, the spoiler includes:

[0031] Mounting plate, fixed at the mounting port;

[0032] The baffle bar is connected to the mounting plate at one end and extends into the flushing pipe at the other end.

[0033] Furthermore, each spoiler contains multiple spoiler rods, which are spaced apart, and the multiple spoiler rods in adjacent spoilers are staggered in the horizontal direction.

[0034] Furthermore, the baffle bar extends downwards at an angle along the axial direction of the flushing pipe, with a gap between the baffle bar and the bottom surface of the flushing pipe to allow molybdenum-containing dust to pass through.

[0035] Furthermore, the baffle rod is a hollow structure with an open lower end. An air pipe connected to the baffle rod is provided on the upper part of the mounting plate. An external air source is connected to the air pipe to supply air into the baffle rod to blow away and transport the molybdenum-containing dust or ash clumps that have settled on the bottom surface of the flushing pipe.

[0036] Furthermore, the spoiler also includes:

[0037] A sealing ring is located at the bottom of the mounting plate and is fitted over the outside of the spoiler bar to form an interference fit seal with the mounting port.

[0038] Compared with the prior art, the beneficial effects of this application are:

[0039] By linking the quantitative feeding mechanism with the rotary valve, the changes in the material level in the ash hopper are detected by the upper and lower level gauges, and the rotary valve is automatically triggered to start and stop without manual intervention, thus realizing the quantitative emission of molybdenum-containing dust.

[0040] By linking the electronically controlled valve with the quantitative feeding mechanism, the flushing water is opened synchronously during ash discharge and discharged quantitatively according to the preset time, so that the ratio of single ash discharge volume to single flushing water volume remains constant. Compared with the crude method of flushing water immediately after ash discharge from any ash hopper in the prior art, this application effectively reduces ineffective flushing water, reduces water consumption, and at the same time makes the concentration of ash-water mixture entering the sludge collection tank relatively stable, which is conducive to subsequent stirring and flotation recovery.

[0041] By installing a pneumatic vibrator on the outer wall of the ash hopper and interlocking it with the upper and lower level gauges, a pulse-type vibration force is applied to the ash hopper during the ash discharge process, which effectively prevents molybdenum-containing dust from bridging and clogging inside the ash hopper.

[0042] By setting up a stirring mechanism in the sludge collection tank, the stirring rod passes through the gap between adjacent auxiliary rods when it rotates with the installation rod, and cooperates with the auxiliary rod to form a shearing gap. This applies shearing force to the ash clumps in the mixture and breaks them up. The combination of stirring and shearing makes the molybdenum-containing dust evenly dispersed in the water, forming a slurry with a stable concentration, which provides strong support for the subsequent flotation process.

[0043] By installing a baffle inside the flushing pipe, molybdenum-containing dust is disturbed and dispersed as it flows through the baffle. The dust is then blown downwards by an external air source through an air pipe, pneumatically blowing and conveying the molybdenum-containing dust or ash clumps that have settled at the bottom of the pipe. The combination of mechanical baffle and pneumatic blowing effectively improves the mixing efficiency of molybdenum-containing dust and water and reduces the risk of pipe blockage.

[0044] This invention not only enables the proportional and quantitative flushing and discharge of molybdenum-containing dust to ensure a constant ash-to-water ratio, but also efficiently mixes the molybdenum-containing dust with water, thereby achieving fully automatic ash discharge and resource recovery.

Detailed Implementation

[0051] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0052] Please refer to the instruction manual appendix. Figure 1-5 This utility model provides a technical solution:

[0053] This embodiment provides a dust removal device for a molybdenum mine dust collector. Please refer to the attached instruction manual. Figure 1 and 2 The dust collector includes a sintered plate dust collector 1. Inside the casing of the sintered plate dust collector 1, multiple ash hoppers 1.1 are arranged sequentially along the length. The sintered plate dust collector 1 uses rigid sintered plates as filter elements. After molybdenum-containing dust is intercepted by the sintered plates, it is cleaned by pulse jet cleaning and falls into the corresponding ash hopper 1.1 below. Each ash hopper 1.1 has a conical structure, with its upper opening connected to the dust collector casing and its lower opening connected to a discharge pipe 1.1.1. From top to bottom, a slide gate valve 1.1.2 and a rotary valve 1.1.3 are installed on the discharge pipe 1.1.1. The slide gate valve 1.1.2 is used to manually cut off the discharge channel during maintenance or emergency situations, and the rotary valve 1.1.3 is used to discharge the molybdenum-containing dust from the ash hopper 1.1.

[0054] Each ash hopper 1.1 is equipped with a quantitative feeding mechanism 2, which is linked with the star-shaped unloader 1.1.3 to intermittently discharge molybdenum-containing dust from the ash hopper 1.1 according to a preset ash amount. When the molybdenum-containing dust in the ash hopper 1.1 reaches the preset material level, the quantitative feeding mechanism 2 triggers the star-shaped unloader 1.1.3 to start ash discharge.

[0055] A flushing pipe 3 extending along the length of the dust collector is installed below the ash hopper 1.1. The outlets of the discharge pipes 1.1.1 of multiple ash hoppers 1.1 are all connected to the flushing pipe 3, so that the molybdenum-containing dust discharged from each ash hopper 1.1 falls into the same flushing pipe 3. One end of the flushing pipe 3 is equipped with an electric control valve 4, and the other end is connected to the sludge collection tank 5. The electric control valve 4 is linked with the quantitative feeding mechanism 2, and is used to open synchronously when the quantitative feeding mechanism 2 discharges ash and discharge flushing water in a preset amount of time, so that the molybdenum-containing dust is flushed and transported along the flushing pipe 3.

[0056] During operation, when the molybdenum-containing dust in any ash hopper 1.1 reaches the preset material level, the quantitative feeding mechanism 2 triggers the star-shaped unloader 1.1.3 to start ash discharge. At the same time, the electric control valve 4 opens synchronously, discharging a quantitative amount of flushing water into the flushing pipe 3. After the molybdenum-containing dust falls into the flushing pipe 3, it is transported along the pipe towards the sludge collection tank 5 under the action of water flow. The sludge collection tank 5 receives the mixture of molybdenum-containing dust and water. The stirring mechanism 6 performs secondary stirring and mixing of the mixture to produce a slurry with uniform concentration. A sludge discharge port 5.1 is provided on one side of the bottom of the sludge collection tank 5. The slurry is pumped through the sludge discharge port 5.1 to the flotation workshop for mineral processing and recovery.

[0057] In this embodiment, the electric control valve 4 is an electric regulating valve installed at the inlet end of the flushing pipe 3. The electric regulating valve is linked with the quantitative feeding mechanism 2. When the quantitative feeding mechanism 2 triggers the star-shaped unloader 1.1.3 to start ash discharge, the electric control valve 4 opens synchronously. The electric control valve 4 discharges flushing water quantitatively according to a preset time. The preset time is calculated and determined based on the single ash discharge volume and the target ash-to-water ratio. For example, if the single ash discharge volume is 10kg and the target ash-to-water ratio is 1:5, then 50kg of flushing water is required. Based on the inner diameter of the flushing pipe 3 and the water flow velocity, the time required to discharge 50kg of water is calculated and set as the opening time of the electric control valve 4. When the opening time reaches the set value, the electric control valve 4 automatically closes and stops water supply. The electric control valve 4 can also be used in conjunction with a flow meter. The flow meter is installed on the flushing pipe 3 to measure the cumulative flow in real time. When the cumulative value of the flow meter reaches the preset target value, the electric control valve 4 closes. This method is more accurate than simple time control and is not affected by water pressure fluctuations.

[0058] Through the above quantitative control method, the ratio of single ash discharge to single flushing water volume remains constant, so that the concentration of the ash-water mixture entering the sludge collection tank 5 is relatively stable, which is beneficial to the secondary mixing of the subsequent stirring mechanism 6 and the mineral processing and recovery in the flotation workshop.

[0059] Example 2, please refer to the appendix of the instruction manual. Figure 2 To achieve efficient quantitative feeding of ash hopper 1.1, the quantitative feeding mechanism 2 includes an upper level gauge 2.1, a lower level gauge 2.2, a solenoid valve 2.3, and a pneumatic vibrator 2.4. The upper level gauge 2.1 is installed on the upper part of the side wall of the ash hopper 1.1, and the lower level gauge 2.2 is installed on the lower part of the side wall of the ash hopper 1.1. Both the upper level gauge 2.1 and the lower level gauge 2.2 are rotary paddle level gauges, with their detection blades extending into the interior of the ash hopper 1.1. The pneumatic vibrator 2.4 is installed on the outer wall of the ash hopper 1.1, and its pipeline is equipped with a solenoid valve 2.3. The solenoid valve 2.3 is interlocked with the upper level gauge 2.1 and the lower level gauge 2.2.

[0060] When the molybdenum-containing dust in the ash hopper 1.1 accumulates to the position of the upper level gauge 2.1, the detection blades of the upper level gauge 2.1 stop rotating due to the obstruction of the material, and output a high level signal. This signal triggers the start of the rotary valve 1.1.3. At the same time, the solenoid valve 2.3 opens, and the pneumatic vibrator 2.4 starts working. The pneumatic vibrator 2.4 applies a pulse-type vibration force to the outer wall of the ash hopper 1.1 to prevent the molybdenum-containing dust from bridging inside the ash hopper 1.1. The rotary valve 1.1.3 continues to operate, discharging the molybdenum-containing dust through the discharge pipe 1.1.1.

[0061] When the material level in the ash hopper 1.1 drops below the lower level gauge 2.2, the detection blades of the lower level gauge 2.2 resume free rotation and output a low level signal. This signal controls the rotary valve 1.1.3 to stop operating, and at the same time, the solenoid valve 2.3 closes and the pneumatic vibrator 2.4 stops working. Thus, one ash discharge cycle ends.

[0062] In this embodiment, the volume difference between the upper level gauge 2.1 and the lower level gauge 2.2 is the preset ash amount for a single ash discharge. By selecting different specifications of ash storage hoppers 1.1 and setting the distance between the upper and lower level gauges, the amount of molybdenum-containing dust discharged each time can be determined.

[0063] Example 3, please refer to the appendix of the instruction manual. Figure 1 and 3 To thoroughly mix the molybdenum dust and water mixture in the collection tank 5 and provide strong support for subsequent flotation, the stirring mechanism 6 includes a motor 6.1, a mounting rod 6.2, multiple stirring rods 6.3, and multiple auxiliary rods 6.4. The motor 6.1 is installed on the upper part of the collection tank 5, with its output end extending downward into the inner cavity of the collection tank 5. The mounting rod 6.2 is horizontally set on the upper part of the inner cavity of the collection tank 5, with its middle part connected to the output end of the motor 6.1 and driven to rotate by the motor 6.1. The multiple stirring rods 6.3 are vertically set below the mounting rod 6.2 and spaced apart along the axial direction of the mounting rod 6.2. The upper end of the stirring rod 6.3 is fixedly connected to the mounting rod 6.2, and the lower end extends downward. When the motor 6.1 drives the mounting rod 6.2 to rotate, the multiple stirring rods 6.3 rotate together with the mounting rod 6.2 to stir the molybdenum dust and water mixture in the collection tank 5.

[0064] Multiple auxiliary rods 6.4 are erected on the bottom surface of the sludge collection tank 5 and spaced apart along the axial direction of the mounting rod 6.2. The lower end of the auxiliary rod 6.4 is fixedly connected to the bottom surface of the sludge collection tank 5, and the upper end extends upward. The stirring rod 6.3 and the auxiliary rod 6.4 are staggered in the horizontal direction. The gap between adjacent auxiliary rods 6.4 is located on the rotation trajectory of the stirring rod 6.3. Both the stirring rod 6.3 and the auxiliary rod 6.4 are made of wear-resistant stainless steel to cope with the abrasiveness of molybdenum dust.

[0065] When the motor 6.1 drives the mounting rod 6.2 to rotate, the stirring rod 6.3 passes through the gap between the adjacent auxiliary rod 6.4, and a shear gap is formed between the stirring rod 6.3 and the auxiliary rod 6.4. Shear force is applied to the ash clumps in the mixture that have not been completely dispersed, and the ash clumps are broken up. At the same time, the rotation of the stirring rod 6.3 causes the mixture to circulate in the sludge collection tank 5, which promotes the full mixing of molybdenum dust and water.

[0066] Example 4, please refer to the appendix to the instruction manual. Figure 4 and 5 To ensure efficient mixing of molybdenum-containing dust with flushing water during transport within the flushing pipe 3, multiple mounting ports 3.1 are spaced along the axial direction of the flushing pipe 3. Each mounting port 3.1 is detachably fitted with a baffle 7, which includes a mounting plate 7.1, a baffle rod 7.2, a sealing ring 7.3, and an air pipe 7.4. Specifically, the mounting plate 7.1 is fixed to the mounting port 3.1, one end of the baffle rod 7.2 is connected to the mounting plate 7.1, and the other end extends into the flushing water. Inside pipe 3, each baffle 7 contains multiple baffle rods 7.2, which are spaced apart. The multiple baffle rods 7.2 in adjacent baffles 7 are staggered in the horizontal direction, that is, the baffle rods 7.2 of one baffle 7 are staggered from the baffle rods 7.2 of the adjacent baffle 7 in the axial direction of the pipe. The sealing ring 7.3 is set at the lower part of the mounting plate 7.1 and sleeved on the outside of the baffle rods 7.2. The sealing ring 7.3 is interference-fitted with the mounting port 3.1 to prevent gray water from leaking from the mounting port 3.1.

[0067] In this embodiment, the baffle rod 7.2 extends downward at an angle along the axial direction of the flushing pipe 3. A gap is left between the baffle rod 7.2 and the inner bottom surface of the flushing pipe 3 to allow molybdenum-containing dust to pass through. When the molybdenum-containing dust passes through the baffle rod 7.2 with the water flow, the baffle rod 7.2 disturbs the water flow and dust, breaking up the dust agglomerates. Since there is a gap between the baffle rod 7.2 and the inner bottom surface of the pipe, even if the dust agglomerates are partially blocked by the baffle rod 7.2, they can still pass through the baffle rod 7.2 and the lower end with the flushing water, without forming a blockage at the baffle rod 7.2.

[0068] In this embodiment, the baffle rod 7.2 is a hollow structure with an open lower end. The upper part of the mounting plate 7.1 is provided with an air pipe 7.4 that is connected to the baffle rod 7.2. The air pipe 7.4 is connected to an external air source to supply air into the baffle rod 7.2. The gas is ejected from the open lower end of the baffle rod 7.2 through the interior of the baffle rod 7.2 to blow away and transport the molybdenum-containing dust or ash clumps that have settled on the bottom surface of the flushing pipe 3.

[0069] The 7.2 baffle bar serves both a mechanical turbulence function and a pneumatic purging function. The mechanical turbulence disperses dust clumps in the water flow, while the pneumatic purging prevents dust from depositing at the bottom of the pipe. The combination of these two functions effectively improves the mixing efficiency of molybdenum-containing dust and water, and reduces the risk of pipe blockage.
