Description

Technical Field

[0001] This application relates to the field of conveying equipment technology, and in particular to an intelligent wind control dust suppression and material guiding trough system. Background Technology

[0002] Coal conveying equipment refers to devices used for transporting coal. Their installation forms can be divided into two types: coal conveying corridors and coal conveying trestle bridges. Coal conveying corridors are similar to underground trenches, generally underground or semi-underground concrete structures. Conveyors are installed within the corridors, and coal is transported through the corridors using conveyors. Coal conveying trestle bridges are generally made of steel structures, erected overhead, and may be enclosed or open. Conveyors are installed on top to transport coal. Transportation methods include belt conveying, pneumatic conveying, and pipeline conveying, with belt conveying being the most widely used.

[0003] In the coal conveying system, material guiding devices are installed at the connection between the coal chute and the conveyor belt. The material guide chute is one of the main pieces of equipment. Various air control, dust suppression and cleaning devices are installed on the material guide chute to mitigate the impact airflow and dust generated when the coal falls onto the conveyor belt, as well as to clean the conveyor belt regularly.

[0004] However, existing intelligent wind control dust suppression material guide trough systems have the following defects: for example, the atomizing mechanism used for atomized dust suppression is usually in an exposed state, and the nozzle is easily blocked by dust, thus affecting the stability and controllability of the atomized dust suppression function. Summary of the Invention

[0005] The purpose of this application is to provide an intelligent wind-controlled dust suppression material guide trough system with a more stable and controllable atomization dust suppression function.

[0006] To achieve the above objectives, this application provides an intelligent wind-controlled dust suppression and material guiding trough system: including a frame and a feeding mechanism, the main body of which is a V-shaped conveyor belt passing through the frame. A set of idlers is installed on the frame to support the upper part of the V-shaped conveyor belt. An overflow prevention tunnel is fixedly connected to the frame, located above the upper part of the V-shaped conveyor belt. A feeding device, a circulation return device, and a damping dust suppression device are installed on the overflow prevention tunnel. The circulation return device and the damping dust suppression device are both located between the feeding device and the upper part of the V-shaped conveyor belt. On the side of the V-shaped conveyor belt with the same direction of movement, the circulating return device and the damping dust suppression device are arranged on the overflow prevention tunnel and along the extension direction of the overflow prevention tunnel. The circulating return device is adapted to balance the air pressure between the V-shaped conveyor belt and the overflow prevention tunnel while reducing the airflow velocity. The damping dust suppression device is adapted to further reduce the wind speed while adsorbing dust. The frame is also equipped with a detection mechanism and a misting dust suppression mechanism. The detection mechanism is adapted to monitor the working environment, and the misting dust suppression mechanism is adapted to generate dry fog for misting dust suppression.

[0007] As a preferred embodiment, the upper section of the V-shaped conveyor belt has a regular V-shape cross-section, and the lower section has an inverted V-shape cross-section. The idler roller group includes a limit roller group and a buffer roller group. The limit roller group is suitable for preventing the V-shaped conveyor belt from deviating. The buffer roller group is distributed entirely below the discharge port of the feeding device, which is suitable for providing buffering for the material falling into the feeding device. On the upper part of the V-shaped conveyor belt, which is outside the direct area below the feeding device, the limit roller group and the buffer roller group are arranged alternately to take into account both buffering and limiting functions.

[0008] As a preferred embodiment, the buffer roller assembly includes a rigid plate, the two ends of which are fixedly connected to the frame via connecting plates. A horizontal floating roller and two inclined floating rollers are rotatably connected to the rigid plate via a transducer assembly. The horizontal floating roller is located between the two inclined floating rollers. The horizontal floating roller is adapted to contact the V-shaped bottom surface of the upper part of the V-shaped conveyor belt, and the inclined floating rollers are adapted to contact the V-shaped side surface of the V-shaped conveyor belt, thus effectively maintaining the shape of the V-shaped conveyor belt.

[0009] As a preferred embodiment, the transducer assembly includes a constraint frame, within which a floating bushing is slidably fitted. A buffer spring is provided between the bottom of the floating bushing and the constraint frame. The floating bushing has an end shaft hole. The two ends of the floating roller have coaxial jumping end shafts, suitable for engaging with the end shaft holes to form a rotating pair. A limit clamp is also fixedly connected to the upper end of the constraint frame. An elastic liner is provided on the inner side of the limit clamp, suitable for direct contact with the floating bushing to avoid noise and damage caused by hard contact.

[0010] As a preferred embodiment, the constraint frame includes a base fixedly connected to the rigid plate. The base has a pair of parallel and symmetrical guide plates, and guide rails on opposite sides of the two guide plates. The outer surface of the floating bushing has a side sliding groove, suitable for cooperating with the guide rails to form a sliding pair. Each guide plate has a lower ear plate at its upper end, and the two sides of the limiting hoop have upper ear plates, suitable for fixed connection with the corresponding lower ear plate. The lower end of the floating bushing has an upper embedded post, suitable for embedding the upper end of the buffer spring, and the upper end face of the base has a lower embedded post, suitable for embedding the lower end of the buffer spring. The base of the transducer assembly located at the higher end of the inclined floating roller is fixedly connected to the rigid plate through a high bracket, and the base of the transducer assembly located at the lower end of the inclined floating roller is fixedly connected to the rigid plate through a low bracket, ensuring the stability of the buffer roller assembly.

[0011] As a preferred embodiment, the limiting roller assembly includes an elastic plate. Both ends of the elastic plate are fixedly connected to the frame via connecting plates. A high-shaft frame and a low-shaft frame are fixedly connected to the elastic plate. One high-shaft frame and one low-shaft frame form a group, and there are two groups on each elastic plate. Two low-shaft frames are located between two high-shaft frames. The upper ends of the high-shaft frames and low-shaft frames in the same group are rotatably connected to a fixed roller. The fixed roller has coaxial fixed end shafts at both ends, which respectively cooperate with the upper ends of the high-shaft frame and the low-shaft frame to form a rotating pair. The higher end of the fixed roller also has a coaxial blocking flange. The diameter of the blocking flange is larger than the diameter of the fixed roller body to prevent the conveyor belt from deviating.

[0012] As a preferred embodiment, the atomizing dust suppression mechanism includes a clean water tank, a high-pressure pump, a pressure relief valve, and a centrifugal atomizer. The centrifugal atomizer has an inlet and an outlet. The inlet is connected to one end of the high-pressure pump via a pipe, and the other end of the high-pressure pump is connected to the clean water tank via a pipe. The outlet is connected to one end of the pressure relief valve via a pipe, and the other end of the pressure relief valve is connected to the clean water tank via a pipe. The high-speed water flow generated by the high-pressure pump pressurizes the clean water and passes through the centrifugal atomizer, where a portion of it is transformed into dry mist. The high-speed sprayed clean water is broken into smaller droplets by the shearing action of centrifugal force, thus allowing it to remain suspended in the air for a long time.

[0013] As a preferred embodiment, the centrifugal atomizer includes a housing, a water supply cap, a return spring, a piston ring, a drive core, a telescopic cylinder, and a limiting cap. The housing includes a cylinder with one open end and a coaxial isolation ring at the other end, the isolation ring having a coaxial central hole. The drive core includes an inner cylinder with a water inlet hole penetrating the inner and outer walls. One end of the inner cylinder has a drain hole, and the other open end has a coaxial rotating ring. The end face of the rotating ring facing away from the inner cylinder has several blades equidistantly arranged around the axis. The inner cylinder is adapted to pass through the central hole to form a rotating pair, and a smooth groove is formed on the outer surface of the inner cylinder. The open end of the water supply cap is fixedly connected to the isolation ring, and all the blades are located inside the water supply cap. The end and the outlet end are on the same straight line, which is always perpendicular to the axis of the drive core and always intersects with some blades; the telescopic cylinder includes an outer cylinder, the inner wall of which has a smooth strip adapted to cooperate with the smooth groove to form a sliding pair, and the side wall of the outer cylinder is provided with a plurality of precision nozzles. The outer cylinder is open at one end facing the isolation ring and has a coaxial blocking ring, while the end facing away from the isolation ring is closed; the piston ring is adapted to be fitted on the outer cylinder and is located at the end of the blocking ring facing away from the isolation ring; the limiting cover includes an inner ring, which is adapted to be fixed inside the open end of the cylinder, and the closed end of the outer cylinder is adapted to extend through the inner ring to the outside of the cylinder, thereby exposing the precision nozzles to spray dry mist into the environment.

[0014] Further preferably, the end face of the isolation ring facing away from the cylinder also has a constraint ring, and the rotating ring is located inside the constraint ring; the extending direction of the smooth groove is parallel to the axis of the inner cylinder, and there are several smooth grooves, which are equidistantly arranged around the axis of the inner cylinder, and the number and position of the smooth strips correspond to the smooth grooves; these precision nozzles are evenly arranged along the axis of the outer cylinder; the end of the blocking ring facing away from the isolation ring has a coaxial rolling groove, and the end face of the piston ring facing the blocking ring has several accommodating cavities arranged equidistantly around the axis, each accommodating cavity is provided with a ball, and all the balls are adapted to roll along the rolling groove; the closed end of the outer cylinder also has a coaxial and larger diameter cover plate, and the end of the limiting cover facing away from the cylinder also has a coaxial annular groove, which is adapted to fit with the cover plate to prevent dust from entering the centrifugal atomizer.

[0015] As a preferred embodiment, the overflow prevention tunnel includes an upper cover, and side skirts are fixedly connected to the sides of the upper cover that are parallel to the direction of movement of the V-shaped conveyor belt. The lower edges of the side skirts on opposite sides are close to each other and located above the upper part of the V-shaped conveyor belt. The side skirts are fixedly connected to the frame. End baffles are fixedly connected to the ends of the upper cover and the two side skirts to prevent airflow and dust from overflowing from the ends of the overflow prevention tunnel.

[0016] As a preferred embodiment, the feeding mechanism further includes configuration frames located at both ends of the V-shaped conveyor belt. Each configuration frame is rotatably connected to a drive roller. The drive roller includes a cylindrical portion adapted to contact the middle of the V-shaped conveyor belt. The cylindrical portion also has a coaxial frustum portion, the diameter of which gradually increases away from the cylindrical portion. A drive mechanism is also provided on the configuration frame. The drive mechanism includes a motor and a reducer fixedly connected to the configuration frame. The output end of the reducer is adapted to pass through the configuration frame and be coaxially connected to the drive roller to provide smooth power to the drive roller.

[0017] Compared with the prior art, the beneficial effects of this application are as follows: (1) By rationally designing the internal structure of the centrifugal atomizer, when atomization is not required and the high-pressure water supply stops, the reset spring inside the centrifugal atomizer will cause the telescopic cylinder to retract into the housing and be sealed by the baffle plate, effectively avoiding the influence of dust on the precision nozzle, thereby ensuring the stability and reliability of the atomization dust suppression mechanism during operation. (2) The centrifugal atomizer used in this system can make the precision nozzle rotate at high speed while spraying water using high pressure water, so as to release dry fog efficiently and achieve rapid and timely atomization dust suppression. (3) By designing a roller group structure with limiting rolling resistance and buffer roller group, the working stability of the conveyor belt is improved, the hard impact of materials falling on the conveyor belt is reduced, the damage to the components caused by impact is reduced, the service life of the components is extended, and the noise of the guide chute during operation is also reduced.

[0040] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0041] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0042] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0043] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0044] like Figure 1-21 The intelligent dust suppression and material guiding trough system shown includes a frame 1 and a feeding mechanism 2. The frame 1 is fixedly installed. The main body of the feeding mechanism 2 is a V-shaped conveyor belt 201 passing through the frame 1. The upper part of the V-shaped conveyor belt 201 has a regular V-shape cross-section, and the lower part has an inverted V-shape cross-section. The feeding mechanism 2 also includes configuration frames 203 located at both ends of the V-shaped conveyor belt 201. The configuration frames 203 are also fixedly installed. Each configuration frame 203 is rotatably connected to a drive roller 240. The specific structure of the drive roller 240 includes a horizontally axial cylindrical part 241 for contacting the middle part of the V-shaped conveyor belt 201. The cylindrical part 241 also has a coaxial... The diameter of the frustum portion 242 gradually increases away from the cylindrical portion 241. The two frustum portions 242 of the drive roller 240 are symmetrical about the cylindrical portion 241, so that the radial cross section of the drive roller 240 is also V-shaped. The mounting frame 203 is also provided with a drive mechanism 220. The drive mechanism 220 includes a motor 221 and a reducer 222 fixedly connected to the mounting frame 203. The output end of the motor 221 is connected to the input end of the reducer 222. The output end of the reducer 222 passes through the mounting frame 203 and is coaxially connected to the drive roller 240, thereby providing stable rotational power to the drive roller 240.

[0045] The frame 1 is equipped with a set of idler rollers 9, which is used to support the upper part of the V-shaped conveyor belt 201. The set of idler rollers 9 includes a set of limit rollers 920 and a set of buffer rollers 930. The set of limit rollers 920 can prevent the V-shaped conveyor belt 201 from running off-center, and the feeding device 4 can provide buffering for the V-shaped conveyor belt 201 and the material on it.

[0046] An overflow prevention tunnel 3 is fixedly connected to the frame 1. The overflow prevention tunnel 3 is located above the upper part of the V-shaped conveyor belt 201. On the one hand, it can prevent materials from falling outside the V-shaped conveyor belt 201, and on the other hand, it can prevent the airflow and dust from escaping into the environment. The overflow prevention tunnel 3 includes an upper cover 301. The upper cover 301 and the side parallel to the direction of movement of the V-shaped conveyor belt 201 are fixedly connected to downward-extending side skirts 302. The lower edges of the side skirts 302 on opposite sides are close to each other. The projections of the side skirts 302 on both sides in the horizontal plane are located between the two sides of the V-shaped conveyor belt 201. Both side skirts 302 are located above the upper part of the V-shaped conveyor belt 201. The ends of the upper cover 301 and the two side skirts 302 are fixedly connected to end baffles 303, which can prevent airflow and dust from overflowing from the ends of the overflow prevention tunnel 3 to a certain extent. The side skirts 302 are fixedly connected to the frame 1 to ensure the stability of the entire overflow prevention tunnel 3 relative to the V-shaped conveyor belt 201.

[0047] On the overflow prevention tunnel 3, that is, on the upper cover 301, there is a feeding device 4, a circulation return device 5, and a damping dust suppression device 6. The feeding device 4 is usually close to the starting end of the movement of the upper part of the V-shaped conveyor belt 201. It should be noted that: all the buffer roller groups 930 are distributed directly below the discharge port of the feeding device 4, and the limiting roller group 920 can only be set at the edge of the discharge port of the feeding device 4. The densely distributed buffer roller group 930 can provide effective buffering for the material falling in the feeding device 4. The V-shaped conveyor belt 201 is located on the upper part of the V-shaped conveyor belt 201, which is not directly below the feeding device 4. The material on the V-shaped conveyor belt 201 is relatively stable, and the demand for buffering function is not high. Therefore, the limiting roller group 920 and the buffer roller group 930 can be arranged alternately.

[0048] The buffer roller assembly 930 includes a rigid plate 931, typically an isosceles right-angled metal plate, horizontally placed with its apex facing upwards, perpendicular to the direction of movement of the V-shaped conveyor belt 201. The two ends of the rigid plate 931 are fixedly connected to the frame 1 via connecting plates 901. A horizontal floating roller 935 and two inclined floating rollers 935 are rotatably connected to the rigid plate 931 via a transducer assembly 932. The horizontal floating roller 935 is located between the two inclined floating rollers 935. The two inclined floating rollers 935 on the same rigid plate 931 are symmetrically arranged about the vertical plane. The horizontal floating roller 935 contacts the V-shaped bottom surface of the upper part of the V-shaped conveyor belt 201, while the inclined floating rollers 935 contact the V-shaped side surface of the V-shaped conveyor belt 201.

[0049] The transducer assembly 932 includes a constraint frame 9321 fixedly connected to the rigid plate 931. A floating bushing 9322 is slidably fitted inside the constraint frame 9321. A buffer spring 9323 is provided between the bottom of the floating bushing 9322 and the constraint frame 9321. The floating bushing 9322 has an end shaft hole 93221. The two ends of the floating roller 935 have coaxial jumping end shafts 9351, which cooperate with the end shaft hole 93221 to form a rotating pair.

[0050] The upper end of the constraint frame 9321 is also fixedly connected to a limit hoop 9324 to prevent the floating bushing 9322 from detaching from the upper open end of the constraint frame 9321. An elastic inner liner 93241 is also provided on the inner side of the limit hoop 9324. The elastic inner liner 93241 is semi-circular and made of rubber material. It is used to directly contact the floating bushing 9322 to avoid the floating bushing 9322 from making hard contact and impact with the limit hoop 9324.

[0051] The constraint frame 9321 includes a base support 93211 fixedly connected to the rigid plate 931. The base support 93211 has a pair of parallel and symmetrical guide plates 93213. Each of the two guide plates 93213 has a guide rail 93214 on its opposite side. The outer symmetrical side of the floating bushing 9322 is provided with a side sliding groove 93222, which is used to cooperate with the guide rail 93214 to form a sliding pair, which can effectively constrain the floating bushing 9322 and ensure the smooth movement of the floating bushing 9322 relative to the constraint frame 9321.

[0052] In some embodiments, each guide plate 93213 has a lower ear plate 93215 at its upper end, and the two sides of the limiting hoop 9324 have upper ear plates 93242, which can be fixedly connected to the corresponding lower ear plate 93215.

[0053] In some embodiments, the lower end of the floating bushing 9322 has an upper insert post 93223, which can be inserted into the upper end of the buffer spring 9323, and the upper end face of the base 93211 has a lower insert post 93212, which can be inserted into the lower end of the buffer spring 9323.

[0054] In some embodiments, the base 93211 of the transducer assembly 932 located at the higher end of the inclined floating roller 935 is fixedly connected to the rigid plate 931 via a high bracket 933, and the base 93211 of the transducer assembly 932 located at the lower end of the inclined floating roller 935 is fixedly connected to the rigid plate 931 via a low bracket 934, so that the inclined floating roller 935 can be stably set on the flat rigid plate 931.

[0055] The limiting roller assembly 920 includes an elastic plate 921 made of elastic alloy material. Both ends of the elastic plate 921 are fixedly connected to the frame 1 via connecting plates 901. A high shaft frame 923 and a low shaft frame 924 are fixedly connected to the elastic plate 921. The high shaft frame 923 and the low shaft frame 924 are both located between the two fixed ends of the elastic plate 921. One high shaft frame 923 and one low shaft frame 924 form a group. There are two groups on each elastic plate 921. The two low shaft frames 924 are located between the two high shaft frames 923. The two groups of shaft frames are symmetrical about the center of the elastic plate 921. The upper ends of the high shaft frame 923 and the low shaft frame 924 in the same group are rotatably connected to a fixed roller 922. The two ends of the fixed roller 922 have coaxial fixed end shafts 9222, which cooperate with the upper ends of the high shaft frame 923 and the low shaft frame 924 respectively to form a rotating pair. Compared with the floating roller 935, the fixed roller 922 has higher positional stability.

[0056] The higher end of the fixed roller 922 also has a coaxial blocking edge 9221. The diameter of the blocking edge 9221 is larger than the diameter of the main body of the fixed roller 922, which can effectively prevent the edge of the V-shaped conveyor belt 201 from going out of the range that the fixed roller 922 can support.

[0057] Because the material falling from the feeding device 4 and the material conveyed on the V-shaped conveyor belt 201 will push most of the air and dust to move in the direction of the upper part of the V-shaped conveyor belt 201, the circulating return device 5 and the damping dust suppression device 6 are both located on the same side as the feeding device 4 and the upper part of the V-shaped conveyor belt 201. The circulating return device 5 and the damping dust suppression device 6 are arranged on the overflow tunnel 3 and along the extension direction of the overflow tunnel 3.

[0058] Among them, the circulating return device 5 can balance the air pressure between the V-shaped conveyor belt 201 and the overflow prevention tunnel 3 while reducing the airflow velocity, such as Figure 1 and 3In the illustrated embodiment, two circulating return devices 5 are provided: one closer to the feeding device 4 is the primary stage, and the one farther away from the feeding device 4 is the secondary stage. Each primary circulating return device 5 forms a primary circulating air duct above the overflow prevention tunnel 3. The end of the primary circulating air duct farther from the feeding device 4 connects to the overflow prevention tunnel 3 to form a primary diversion section. The primary diversion section is perpendicular to the overflow prevention tunnel 3, and its cross-section expands from top to bottom. As the material falls, the airflow carrying dust is blocked by the damping dust suppression device 6 and rebounds. Due to the change in space, most of the airflow rebounds into the primary diversion section, and then flows from the primary circulating air duct closer to the feeding device 4 and the overflow prevention tunnel 3. One end of the tunnel 3 connects to the return air outlet. Due to the difference in positive and negative pressure during the return air process, the airflow can continuously circulate in the primary circulation duct and the diversion section, and the pressure is somewhat sluggish. The remaining airflow containing dust continues to flow to the damping dust suppression device 6 and the next circulation return device 5. After passing through multiple obstructions of the damping dust suppression device 6, the airflow will be reduced step by step, and a large amount of dust will be attached and condensed into lumps. When the dust condensation reaches a certain thickness, the dust lumps can fall off under the action of gravity and external force, and be transported away with the material by the V-shaped conveyor belt 201. The expansion design of the primary diversion section can better receive the rebound airflow, allowing more airflow to enter the circulation and further relieve the pressure.

[0059] like Figure 1 and 3 In the embodiment shown, a damping dust suppression device 6 is also provided behind the secondary circulation return device 5, and a secondary circulation air duct is formed above the overflow tunnel 3. The secondary circulation air duct is in the shape of an inverted V. The principle of the secondary circulation return device 5 is similar to that of the primary circulation return device 5, but the secondary circulation return device 5 designs the secondary circulation air duct with a structure with a stronger pressure relief effect, which greatly slows down the flow of air, thereby ensuring that the kinetic energy of the airflow can be exhausted at the subsequent damping dust suppression device 6, reducing or even eliminating the airflow rushing out of the end of the overflow tunnel 3.

[0060] like Figures 1 to 3 In the embodiment shown, the secondary circulation return device 5 is located on the side of the primary circulation return device 5 away from the feeding device 4. By utilizing the different air control and pressure relief mechanisms and performance of the primary and secondary circulation return devices 5 and cooperating with the damping dust suppression device 6, the airflow carrying dust can be effectively suppressed in sequence, so that the airflow pressure is reduced step by step, and the dust content can also be reduced step by step.

[0061] The damping dust suppression device 6 can further reduce the wind speed while adsorbing dust. The damping dust suppression device 6 includes a lifting controller, a mounting frame, and damping components. The lifting controller and the mounting frame are connected. The lifting controller is suitable for raising or lowering the mounting frame. Multiple connecting rods are provided on the mounting frame. The connecting rods are arranged along the width direction of the V-shaped conveyor belt 201. The damping components are suitable for rotating and cooperating with each connecting rod. One damping component is installed for each connecting rod. One damping dust suppression mechanism can install one or more damping components as needed. The damping components are suitable for swinging in the conveying direction on the conveying side of the feeding belt. The swingable design of the damping components can effectively buffer the airflow and avoid strong impact between the airflow and the damping components, which would cause airflow turbulence.

[0062] Generally, two damping dust suppression devices 6 are arranged as a group. When only one damping component is set on each damping dust suppression device 6, the two damping dust suppression devices 6 can also achieve a multi-layer suppression effect by working together.

[0063] In some embodiments, the lifting controller may use a cylinder or an electric telescopic rod, and the damping assembly includes a clamp and a damping curtain. The top of the damping curtain is provided with a connecting part, and the clamp is adapted to cooperate with the connecting part of one or more damping curtains for connection and fixation. The installation has a high degree of freedom, and different numbers of damping curtains can be selected for installation according to needs.

[0064] In this application, the connecting part and the connecting rod are parallel to each other, and the damping curtain can be arranged in the longitudinal section along the surface perpendicular to the feed belt. The more damping curtains there are, the stronger the blocking effect on the airflow and the better the dust suppression effect.

[0065] Specifically, both the clamp and the connecting part are provided with connecting holes, and one or more connecting parts inserted into the clamp can be fastened to the clamp using universal threaded fasteners.

[0066] The damping curtain includes multiple damping strips connected below the connecting part. The damping strips are evenly distributed along the length of the connecting part, and the gaps between the damping strips allow airflow to pass through while trapping dust.

[0067] In some embodiments, the damping strip is made of a polymer material.

[0068] The frame 1 is also equipped with a detection mechanism 8 and a misting dust suppression mechanism 7. The detection mechanism 8 is used to monitor the working environment. The detection mechanism 8 adopts a video infrared temperature sensing sensor, which can monitor parameters such as particulate matter concentration (TSP), temperature, humidity, and wind speed at the outlet of the feed chute in real time. The temperature and humidity parameters can help adjust the spraying time cycle of the misting dust suppression mechanism 7. The intelligent visual control can achieve the best dust suppression effect.

[0069] The atomizing dust suppression mechanism 7 can generate dry fog, which is a fine mist droplet with a particle diameter of less than 10 micrometers. It can remain suspended in the air for a long time without quickly settling. The atomizing dust suppression mechanism 7 includes a clean water tank 701, a high-pressure pump 703, a pressure relief valve 704, and a centrifugal atomizer 750. The centrifugal atomizer 750 has a water inlet end 7521 and a water outlet end 7522. The water inlet end 7521 is connected to one end of the high-pressure pump 703 through a pipe 702. The other end of the high-pressure pump 703 is connected to the clean water tank 701 through a pipe 702. The water outlet end 7522 is connected to one end of the pressure relief valve 704 through a pipe 702. The other end of the pressure relief valve 704 is connected to the clean water tank 701 through a pipe 702. After the high-pressure pump 703 pressurizes the clean water, the high-speed water flow generated passes through the centrifugal atomizer 750, and part of it will turn into dry fog.

[0070] The specific structure of the centrifugal atomizer 750 includes a housing 7510, a water supply cover 7520, a return spring 753, a piston ring 7540, a drive core 7550, a telescopic cylinder 7560, and a limiting cover 7570. The housing 7510 includes a cylinder 7511, one end of which is open and the other end has a coaxial isolation ring 7512. The isolation ring 7512 has a coaxial center hole 7513 in the center, and the end face of the isolation ring 7512 facing away from the cylinder 7511 also has a constraint ring 7514. The drive core 7550 includes an inner cylinder 7553, which has a water inlet hole 7555 penetrating the inner and outer walls. One end of the inner cylinder 7553 has a drain hole 7556, and the other end is open and has a coaxial rotating ring 7551. The rotating ring 7551 is located inside the constraint ring 7514. The end face of the rotating ring 7551 facing away from the inner cylinder 7553 has several blades 7552 arranged equidistantly around the axis, which can be pushed by the water flow to drive the rotating ring 7551 to rotate. The inner cylinder 7553 is suitable to pass through the central hole 7513 to form a rotating pair. The outer surface of the inner cylinder 7553 has a smooth groove 7554. The extension direction of the smooth groove 7554 is parallel to the axis of the inner cylinder 7553. There are several smooth grooves 7554. These smooth grooves 7554 are arranged equidistantly around the axis of the inner cylinder 7553. In this way, the center of mass of the entire drive core 7550 will fall on its own axis of rotation, and polarization is not easy to occur during rotation. The open end of the water supply cover 7520 is fixedly connected to the isolation ring 7512. All blades 7552 are located inside the water supply cover 7520, which can fully contact the water flow. It should be noted that the water inlet end 7521 and the water outlet end 7522 are on the same straight line. This straight line is always perpendicular to the axis of the drive core 7550 and can always intersect with some blades 7552. In this way, the impact of the water flow can continuously act on the moving blades 7552. The telescopic cylinder 7560 includes an outer cylinder 7561. The inner wall of the outer cylinder 7561 has smooth strips 7562. The number and position of the smooth strips 7562 correspond to the smooth grooves 7554, forming a one-to-one sliding pair. The side wall of the outer cylinder 7561 is provided with several precision nozzles 7565, with an orifice diameter of approximately 0.1-0.5 mm. Within a range of mm, these precision nozzles 7565 are evenly arranged along the axis of the outer cylinder 7561. Only the precision nozzles 7565 exposed outside the cylinder 7511 can spray dry mist into the environment. The outer cylinder 7561 is open at one end facing the isolation ring 7512 and has a coaxial blocking ring 7563. The blocking ring 7563 has a coaxial groove 7564 at the end facing away from the isolation ring 7512. The end of the outer cylinder 7561 facing away from the isolation ring 7512 is closed. The closed end of the outer cylinder 7561 also has a coaxial cover plate 7566 with a larger diameter.

[0071] Piston ring 7540 needs to be fitted onto outer cylinder 7561 and located at the end of retaining ring 7563 facing away from isolation ring 7512. Piston ring 7540 is mainly used to drive retaining ring 7563 closer to isolation ring 7512. Piston ring 7540 has several equidistant cavities 7541 on the end face of retaining ring 7563. Each cavity 7541 is provided with a ball 7542. The ball 7542 can roll freely in the cavity 7541, and all the balls 7542 can roll along the groove 7564. In this way, when retaining ring 7563 rotates relative to piston ring 7540, it has extremely low rotational resistance due to the smoothing effect of clean water.

[0072] The limiting cover 7570 includes an inner ring 7571, which needs to be fixed inside the open end of the cylinder 7511. The closed end of the outer cylinder 7561 extends through the inner ring 7571 to the outside of the cylinder 7511. The end of the limiting cover 7570 facing away from the cylinder 7511 is also provided with a coaxial annular groove 7572, which fits perfectly with the cover plate 7566. When the centrifugal atomizer 750 is not in operation, the cover plate 7566 can be completely submerged in the annular groove 7572, thereby preventing dust from entering the cylinder 7511 of the centrifugal atomizer 750.

[0073] The testing agency 8 is usually positioned at the exit of the overflow tunnel 3, which is most likely to generate a large amount of dust. The principle of the testing agency 8 in detecting the concentration of environmental dust can be based on the principle of laser scattering. The dust concentration is calculated by measuring the intensity of the scattered light by irradiating the dust particles in the air at the exit of the overflow tunnel 3 with a laser beam.

[0074] The atomizing dust suppression mechanism 7 is usually located at the port of the overflow tunnel 3, where a large amount of dust is most likely to be generated. Here's a detailed explanation of the working principle of the atomizing dust suppression mechanism 7: When the detection mechanism 8 detects that the concentration of particulate matter in the working environment is too high, the high-pressure pump 703 starts, drawing clean water from the clean water tank 701 and pressurizing it before injecting it into the centrifugal atomizer 750. Once the centrifugal atomizer 750 is full, the internal pressure will rapidly increase, exceeding the set value of the pressure relief valve 704. The pressure relief valve 704 opens, guiding the high-pressure water flow back to the clean water tank 701. As long as the pressure relief valve 704 is open, the water pressure inside the centrifugal atomizer 750 will always be greater than the opening set value of the pressure relief valve 704. The flowing high-pressure water impacts the drive core. The blades 7552 at the end of 7550 force the drive core 7550 to rotate at high speed relative to the housing 7510. The high-pressure water entering the telescopic cylinder 7560 through the drive core 7550 will be discharged through the precision nozzle 7565. However, due to the very small orifice of the precision nozzle 7565, the telescopic cylinder 7560 will be subjected to a large water pressure, which will overcome the elastic force of the return spring 753 and extend out of the cylinder 7511. At the same time, since the drive core 7550 drives the telescopic cylinder 7560 to rotate synchronously, the rotation speed relative to the housing 7510 is directly affected by the water flow speed passing through the water supply cover 7520. The extremely fine water jet sprayed from the precision nozzle 7565 is broken into 5-10μm droplets under the action of centrifugal force.

[0075] Because of its tiny droplet size, dry fog can remain suspended in the air for a long time and does not easily condense into large water droplets, thus it does not easily wet surrounding objects. This characteristic allows it to remain suspended in the air for extended periods, making it widely used in industrial dust suppression, humidification, and cooling applications. However, when dry fog encounters dust, the dust, which is usually at a relatively low temperature, acts as a condensation nucleus, quickly adsorbing the dry fog suspended in the air and forming larger water droplets that fall to the ground, thereby achieving efficient dust suppression in industry.

[0076] After the pressure relief valve 704 is opened, its flow inner diameter quickly reaches the upper limit. At this time, the high-pressure pump 703 increases its power, and the water pressure will increase further. The high-pressure water passing through the water supply cover 7520 and the pressure relief valve 704 will not only increase in pressure, but also increase in flow. The return spring 753 will be under greater pressure and its contraction will be more obvious. The telescopic cylinder 7560 will extend more out of the cylinder 7511, and more precision nozzles 7565 will be exposed and participate in atomization. At the same time, the rotation speed of the outer cylinder 7561 will be faster, and more dry fog will be sprayed into the working environment per unit time.

[0077] When the testing agency 8 detects that the particulate matter concentration in the working environment has returned to normal, the high-pressure pump 703 can stop working and can run in reverse for about 0.5 seconds to remove the clean water from the centrifugal atomizer 750. The water pressure in the centrifugal atomizer 750 drops rapidly, and the telescopic cylinder 7560 loses water pressure support. The return spring 753 will quickly push the piston ring 7540 to drive the blocking ring 7563 to approach the isolation ring 7512 until the cover plate 7566 is completely submerged in the ring groove 7572, isolating the inside of the centrifugal atomizer 750 from the outside world and preventing subsequent dust from affecting the internal structure of the centrifugal atomizer 750.
