Description

Technical Field

[0001] This application relates to the field of material conveying equipment technology, and in particular to a pyrite injection device. Background Technology

[0002] In existing technologies, during the material conveying process, most feeding tanks have only one discharge port, and the material inside the feeding tank is transported to the reactor through only one pipeline. This not only results in insufficient feeding capacity due to low space utilization, but also affects the stability of equipment operation due to the problem of eccentric feeding. At the same time, materials with strong adhesion, such as pyrite, are prone to causing uneven fluidization, material accumulation, and "bridging" problems in the feeding tank, which seriously disrupts the continuity of pneumatic conveying. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a pyrite injection device, which not only solves the problem of insufficient feeding capacity of a single discharge port by setting multiple discharge ports, but also effectively solves the problems of uneven fluidization, material accumulation and "bridging" of pyrite material by setting a turbulence device between adjacent discharge ports.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] This application discloses a pyrite injection device, including a sending tank 1. The bottom of the sending tank 1 is provided with a distribution cone 2 and multiple discharge ports 3, which are evenly arranged around the distribution cone 2. A flow disturbance device 4 is provided between adjacent discharge ports 3. The flow disturbance device 4 includes a flow disturbance component 100 and a first gas supply pipe 200. The flow disturbance component 100 includes a support member 11 and a flow disturbance component 12. One end of the support member 11 is movably connected to the flow disturbance component 12. The other end of the support member 11 extends axially within the first gas supply pipe 200 and is fixedly connected to the inner wall of the sending tank 1. The first end of the first gas supply pipe 200 passes through the side wall of the sending tank 1 and is connected to an external gas source. The second end of the first gas supply pipe 200 is opposite to the flow disturbance component 12 and is used to inject pulsed airflow to make the flow disturbance component 12 reciprocate.

[0031] See Figures 1-4 Multiple discharge ports 3 at the bottom of the sending tank 1 are evenly arranged around the distribution cone 2 to form an annular discharge area, which is conducive to the uniform discharge of materials at the bottom of the tank and can effectively solve the problems of flow asymmetry and local accumulation caused by single-point discharge. Since materials such as pyrite are prone to adhesion, they are very likely to cause problems such as uneven fluidization and bridging in the tank. Therefore, this application provides a special flow disturbance device 4 between adjacent discharge ports 3. The flow disturbance device 4 is fixedly connected to the inner wall of the sending tank 1 through the support member 11, which can make the entire flow disturbance assembly 100 stably installed in the sending tank 1. The first gas supply pipe 200 serves as the driving source of the flow disturbance device 4. Its first end passes through the side wall of the sending tank 1 and is connected to an external pulse gas source, while the second end is set opposite to the flow disturbance member 12. When the compressed gas from the external pulse gas source is ejected in a pulse form through the second end of the first gas supply pipe 200, the pulse airflow provides a periodic impact force to the flow disturbance member 12, thereby driving the flow disturbance member 12 to reciprocate in the material layer.

[0032] When the turbulence component 12 of the turbulence assembly 100 reciprocates under the impact of the pulsed airflow, it can provide a stable turbulence force for the fluidized material in the tank, which is equivalent to continuously agitating the material in the fluidized state, effectively improving the uniformity of fluidization. Furthermore, the reciprocating motion of the turbulence component 12 can dynamically break up material accumulation or static arches that may form at the bottom of the tank, especially in the area around the distribution cone 2 and between the discharge ports 3, effectively preventing material bridging and blockage. In addition, the movement of the turbulence component 12 can continuously loosen the surrounding material, enhance its fluidity, and promote the uniform and stable migration of material to each discharge port 3, ensuring the uniformity of material concentration at each discharge port 3. In summary, the blowing device of this application, through the uniform distribution design of the distribution cone 2 and multiple discharge ports 3, combined with the turbulence device 4 driven by the pulsed airflow, significantly improves the flow reliability of difficult-to-process materials such as pyrite in the conveying tank 1, laying the foundation for subsequent stable and efficient pneumatic conveying.

[0033] Furthermore, the support member 11 includes a connecting rod 111 and a reset member 112. The reset member 112 is disposed inside the connecting rod 111, and one end of both the connecting rod 111 and the reset member 112 is connected to the inner wall of the sending tank 1.

[0034] The spoiler 12 includes a movable rod 121 and a spoiler 122. One end of the movable rod 121 is fixedly connected to the spoiler 122, and the other end of the movable rod 121 is located inside the connecting rod 111 and is fixedly connected to the other end of the reset member 112.

[0035] Specifically, see Figure 3 and Figure 4 The connecting rod 111 is a hollow tubular structure with one end closed. Its closed end or the tube body is fixedly connected to the inner wall of the sending tank 1 by welding or flange, forming a stable mounting base. The reset member 112 is disposed in the internal cavity of the connecting rod 111. One end of the reset member 112 is connected to the inner bottom of the connecting rod 111 or to the inner wall of the sending tank 1, and the other end is connected to the movable rod 121. The turbulence-disrupting member 12 includes the movable rod 121 and the turbulence-disrupting plate 122. The turbulence-disrupting plate 122 is usually designed as a plate-shaped, wedge-shaped, or arch-breaking structure with a certain curved surface. One side of the plate is fixedly connected to one end of the movable rod 121, and the other side acts on the material. The other end of the movable rod 121 extends and inserts into the internal cavity of the connecting rod 111, and is fixedly connected to the other end of the reset member 112. Thus, the turbulence-disrupting member 12 is supported in the connecting rod 111 in a telescoping manner, forming an elastic movable mechanism.

[0036] When the pulsed airflow impacts the baffle 122 from the second end of the first gas delivery pipe 200, the baffle 122 and the movable rod 121 overcome the elastic force of the reset member 112 and move forward along the axial direction of the connecting rod 111. The reset member 112 undergoes elongation deformation, storing force for the rearward movement of the baffle 12. When the pulsed airflow is intermittent or the pressure drops, the reset member 112 recovers its deformation, pulling the movable rod 121 and the baffle 122 to move backward along the axial direction of the connecting rod 111 to reset, thus completing one reciprocating motion. During this motion, the reset member 112 provides a definite restoring force, making the reciprocating motion trajectory of the baffle 12 more stable and predictable, and the arch-breaking turbulence effect more concentrated. For materials with different bulk densities or adhesion forces, the elongation and recovery stroke of the reset member 112 can enable the baffle 12 to generate a certain adaptive turbulence force. Therefore, when the pulsed airflow impacts the spoiler 122, its kinetic energy is directly converted into the reciprocating mechanical motion of the spoiler 122, realizing mechanical arch breaking and turbulence; on the other hand, the airflow impact force is also transmitted to the surrounding materials through the plate.

[0037] Furthermore, the spoiler 122 is provided with a cavity 123, and a through hole 124 is provided on the spoiler 122, the through hole 124 connecting the cavity 123 with the inner cavity of the sending tank 1; the spoiler device 4 also includes a second gas supply pipe 300. The support member 11 is provided with a second gas supply pipe 300, the first end of the second gas supply pipe 300 passes through the side wall of the sending tank 1 and is connected to the fluidizing gas source, and the second end of the second gas supply pipe 300 is connected to the cavity 123.

[0038] To prevent insufficient or uneven distribution of fluidizing gas, which could lead to poor material flowability, an auxiliary fluidization function is added to the turbulence device 4. Specifically, the turbulence plate 122 is either integrally formed or a split structure. The split structure includes a first turbulence plate and a second turbulence plate. The first and second turbulence plates are spatially spaced at a certain distance and are fixedly connected by a side connection structure, thus forming a cavity 123. Multiple through holes 124 are provided on the first turbulence plate, which directly connect the cavity 123 to the inner cavity of the delivery tank 1. The second turbulence plate is positioned opposite the second end outlet of the first gas delivery pipe 200 to directly withstand the impact of the pulsed airflow.

[0039] See Figure 3 When the continuous fluidizing gas from the second gas supply pipe 300 is delivered to the cavity 123 inside the baffle 122, the airflow is released into the material inside the delivery tank 1 in a relatively stable and dispersed stream form through the through holes 124 on the first baffle. The airflow ejected from the through holes 124 can form a high-fluidization-intensity "air cushion" or fluidized layer in a local area in front of the baffle 122, significantly reducing the angle of repose of the material in this area, making it easier to flow, and reducing the abrasion of the baffle 122 by the pyrite material. When the baffle 122 moves forward under the action of pulses, the material in front of it is loosened; at the same time, the fluidizing gas ejected from the through holes 124 further "lubricates" and pushes these loosened materials toward the discharge port 3, preventing them from recompacting. The continuous airflow through the cavity 123 and the through hole 124 can play a certain self-cleaning role on the structure of the baffle 122 itself, especially the through hole 124, to prevent fine particulate materials from accumulating in the cavity 123 or clogging the through hole 124.

[0040] In this embodiment, by integrating pulsed mechanical motion with a continuous fluidizing gas path within the turbulence device 4, the fusion and synergy of "mechanical impact" and "airflow assistance" are achieved. The pulsed airflow intermittently impacts with high intensity to disrupt the initial bridging structure, while the continuous fluidizing gas is distributed and guided through the cavity 123 and through-hole 124 inside the turbulence plate 122, allowing it to act more precisely on the critical area at the bottom of the tank most prone to blockage. This adds further precise fluidization to the traditional bottom overall fluidization, making the material fluidization within the delivery tank 1 more effective. Therefore, the turbulence device 4 of this application is not only a passive mechanical arch-breaking tool but also an active material flow promoter. Through the combined action of air and machinery, it optimizes the flow environment at the bottom of the delivery tank 1, especially in the complex area between the multiple discharge ports 3, ensuring the continuous and stable operation of difficult-to-transport materials such as pyrite in the delivery tank 1.

[0041] Furthermore, the second gas supply pipe 300 is disposed inside the support member 11. The second gas supply pipe 300 includes a straight pipe 31 and a telescopic pipe 32. The straight pipe 31 is located axially inside the movable rod 121, and the telescopic pipe 32 is located axially inside the reset member 112. One end of the straight pipe 31 is connected to the cavity 123 of the turbulence member 12, and the other end is fixedly connected to one end of the telescopic pipe 32. The other end of the telescopic pipe 32 passes through the side wall of the sending tank 1 and is connected to the fluidizing gas source.

[0042] To ensure the reliability and sealing of the gas pipeline during the high-frequency reciprocating motion of the turbulence element 12, the second gas pipeline 300 adopts a segmented structure. See [link / reference] Figure 3 The second gas supply pipe 300 is composed of two main parts: a straight pipe 31 and a telescopic pipe 32. The straight pipe 31 is fixedly installed inside the movable rod 121 and moves with the movable rod 121. Its end near the baffle 122 is fixedly connected to the inlet of the cavity 123. The telescopic pipe 32 is located inside the reset member 112. One end of its telescopic pipe is connected to the other end of the straight pipe 31, and its other end extends axially in the reset member 112 and passes through the side wall of the delivery tank 1 to connect with the fluidizing gas source.

[0043] When the pulsed airflow drives the turbulence-disrupting component 12 to reciprocate, the straight tube 31 inside the movable rod 121 moves accordingly. At this time, the telescopic tube 32 located inside the reset component 112, through its own elastic expansion and contraction, flexibly compensates for the change in pipe length caused by the displacement of the movable rod 121, maintaining the physical continuity of the air passage. Simultaneously, the telescopic tube 32 and its connections at both ends must ensure good airtightness to prevent gas leakage during continuous expansion and contraction. The segmented second air supply pipe 300 ensures that the air supply pipeline does not restrict the movement stroke of the turbulence-disrupting component 12 or cause it to jam, solving the dynamic connection problem between the moving component and the fixed air source. By embedding the telescopic tube 32 within the space of the reset component 112, efficient space utilization is achieved, resulting in a compact overall structure and reducing the risk of external mechanical damage.

[0044] Preferably, the telescopic tube 32 is made of metal corrugated pipe, high-quality rubber hose or special pipe with good telescopic and fatigue resistance properties, and its length design needs to meet the needs of the full-stroke telescopic extension of the turbulence component 12.

[0045] In some implementations, the second gas supply pipe 300 is located on both sides of the support member 11 for connecting the fluidizing gas source and the cavity 123; the second gas supply pipe 300 includes a straight pipe 31 and a telescopic pipe 32, one end of the straight pipe 31 is fixedly connected to one end of the telescopic pipe 32, and the other end of the straight pipe 31 is connected to the fluidizing gas source or the cavity 123.

[0046] Specifically, see Figure 4 At least two second gas supply pipes 300 are provided and are respectively arranged on the outside of the support member 11. The first end of each second gas supply pipe 300 passes through the wall of the sending tank 1 and is connected to an external fluidizing gas source; the second end of each second gas supply pipe 300 is respectively connected to the cavity 123 of the baffle 122 to achieve balanced gas supply.

[0047] Furthermore, the turbulence device 4 also includes an agitation component 400, which is connected to the turbulence component 100 in a transmission manner. When the turbulence component 100 performs reciprocating motion, it drives the agitation component 400 to perform rotational motion.

[0048] Because pyrite materials easily agglomerate to form material lumps, and these lumps are more likely to bridge or block the discharge port 3, the turbulence device 4 is also equipped with an agitator 400. The agitator 400 and the turbulence component 100 are connected by a mechanical transmission mechanism. When the turbulence component 100 reciprocates axially under the drive of pulsed airflow, this transmission connection converts the reciprocating motion into rotational motion that drives the agitator 400 to rotate. The transmission connection is prior art and will not be described in detail here. The agitator 400 includes a rotating rod and multiple blades. The multiple blades are fixedly installed on the outer wall of the rotating shaft. When the agitator 400 rotates under the drive of the reciprocating motion of the turbulence component 100, the rotating shaft drives the blades to rotate. The blades can break up the material lumps in the delivery tank 1, and the rotating blades continuously break the static resting structure of the material, forming a dynamic coordination with the fluidizing gas and pulsed turbulence of the turbulence component 12. Even during the intermittent period of conveying, this compound motion can continue as long as the pressure inside the tank is maintained or purged, effectively preventing secondary settling and compaction of materials due to gravity during the pause. This also significantly improves the adaptability, reliability, and conveying efficiency of the purging device for highly adhesive and easily caking materials such as pyrite.

[0049] Furthermore, the spoiler 122 is umbrella-shaped.

[0050] Specifically, the umbrella-shaped opening of the spoiler 122 surrounds the first air supply pipe 200, and the pulse airflow in the first air supply pipe 200 can all act on the lower surface of the spoiler 122, that is, the second spoiler.

[0051] Furthermore, the turbulence-disrupting assembly 100 also includes a movable cover 500, which is disposed at the second end of the first air supply pipe 200. When the turbulence-disrupting member 12 moves backward, the movable cover 500 can be pushed or released to open or close the second end of the first air supply pipe 200.

[0052] To precisely control the timing of pulsed gas flow release and prevent material inside the tank from backflowing into the gas pipeline under high pressure, a movable cover 500 is installed on the turbulence assembly. (See [reference]). Figure 5 , Figure 6The movable cover 500 is located at the second end opening of the first air supply pipe 200 and is mechanically linked to the movement of the baffle 12. Specifically, at least two movable covers 500 are provided, forming a ring. The inner diameter of the ring matches the diameter of the movable rod 121, and the outer diameter of the ring is slightly larger than the diameter of the first air supply pipe 200. When the baffle 12 moves forward, the pulse air supply stops or the pressure drops sharply. At this time, the elongated reset member 112 begins to recover its deformation, pulling the baffle 12 backward to reset. During this backward movement, the second spoiler of the spoiler 122 contacts and pushes against the outer edge of the movable cover 500. Since the spoiler 122 is umbrella-shaped, the movable cover 500 moves from the wall of the first air supply pipe 200 towards the movable rod 121. Finally, the inner circles of the two movable covers 500 completely fit against the outer wall of the movable rod 121, closing the second end outlet of the first air supply pipe 200. The closed outlet effectively prevents the material or dust in the tank from being sucked in or backflush into the first air supply pipe 200 under the pressure fluctuations in the tank, causing blockage. Until the start of the next pulse cycle, the spoiler 12 is pushed forward again, and the movable cover 500 opens accordingly.

[0053] Furthermore, the movable cover 500 includes a cover body 50, a groove 51 disposed on the lower surface of the cover body 50, and a sliding mechanism 52 disposed at the second end of the first air supply pipe 200. The sliding mechanism 52 cooperates with the groove 51 to drive the cover body 50 to move, thereby enabling the second end of the first air supply pipe 200 to open and close.

[0054] Specifically, a pilot movable plate 53 is provided on the cover 50. The pilot movable plate 53 is hinged to the cover 50. Under the pressure of the pulsed gas, the pilot movable plate 53 will open forward to form an initial airflow channel. Once the initial airflow channel is established, the high-pressure pulsed main airflow will immediately be ejected at high speed from this channel. The initial airflow directly acts on the baffle plate 122, causing the baffle 12 to start moving forward. The pushing force of the baffle 12 on the cover 50 is reduced, and the cover 50 can be opened under the action of the return spring 523. A limit pin is provided on the junction shaft between the pilot movable plate 53 and the cover 50 to prevent the pilot movable plate 53 from failing to close after opening.

[0055] To ensure the smooth opening of the cover 50, a groove 51 is provided on the lower surface of the cover 50, facing the first air supply pipe 200. Simultaneously, a sliding mechanism 52 is fixed at the second end of the first air supply pipe 200, a portion of which is embedded and can slide within the groove 51. When the spoiler 12 moves forward under the impact of the pulsed airflow, the pushing force of the spoiler 122 on the cover 50 decreases, causing the sliding mechanism 52 to rotate within the groove 51, thereby driving the cover 50 to translate and reliably opening the second end of the first air supply pipe 200. The length of the groove 51 is at least equal to the moving distance of the cover 50.

[0056] Furthermore, the sliding mechanism 52 includes a pulley 521, a pull rope 522, and a return spring 523. The pulley 521 is fixed to the second end of the first air supply pipe 200 and located in the sliding groove 51. One end of the pull rope 522 is fixedly connected to the cover 50, and the other end is connected to one end of the return spring 523 via the pulley 521. The other end of the return spring 523 is fixedly connected to the first air supply pipe 200.

[0057] More specifically, pulley 521 is fixedly installed on a side or top bracket at the second end of the first air supply pipe 200. Pull rope 522 is made of high-strength flexible steel cable or fatigue-resistant synthetic fiber rope; one end is fixedly connected to the cover 50, and the other end passes through pulley 521, changes direction, and connects to the upper end of return spring 523. The lower end of return spring 523 is firmly connected to a fixed bracket on or near the side wall of the first air supply pipe 200, providing a stable restoring force reference for the entire linkage system. When the pulsed airflow enters the first gas supply pipe 200, the instantaneous impact of the pulsed airflow on the pilot movable plate 53 opens it forward to form an initial airflow channel. The high-pressure pulsed main airflow immediately sprays out at high speed from this channel. The initial airflow directly acts on the baffle plate 122, so the baffle 12 moves forward under the impact of the pulsed airflow. At this time, the pushing force of the baffle plate 122 on the cover 50 disappears. Under the reset action of its return spring 523, the sliding mechanism 52 pulls the cover 50 away from the movable rod 121 through the pull rope 522, fully opening the first gas supply pipe. When the pulsed airflow disappears, the baffle 12 moves backward under the reset deformation of the reset member 112. At this time, the lower surface of the baffle 12 pushes the cover 50 towards the movable rod 121. The cover 50 is pulled by the pull rope 522, causing the return spring 523 to deform, storing force for the opening of the cover 50. The sliding mechanism 52 is closely coupled with the movement of the spoiler 12. By converting the reciprocating motion of the spoiler 12 into the stretching and releasing of the return spring 523, the opening and closing of the cover 50 is controlled.
