Description

TECHNICAL FIELD

[0001] The present application relates to the field of desulfurizer production, in particular to an adjustable conveying device for desulfurizer production and a use method thereof. BACKGROUND

[0002] Desulfurizer generally refers to a reagent for removing free sulfur or sulfur compounds in fuel, raw materials or other materials, and in the control and treatment of pollutants, it mainly refers to a reagent for removing sulfur oxides in waste gas. Various alkaline compounds can be used as desulfurizers. The desulfurizer for removing sulfur dioxide in flue gas is mostly cheap lime, limestone and alkaline solution prepared by lime reagent. The desulfurizer usually needs to convey powder materials during production.

[0003] The powder material such as desulfurizer has a large internal friction coefficient and is prone to "central flow", that is, only the material vertically falls from the outlet directly above the silo, forming a narrow channel, while the surrounding material is stagnant, forming a dead zone, and eventually the material above forms an arch bridge, causing flow interruption.

[0004] In the prior art, the desulfurizer often fluctuates in water content, bulk density and other parameters during storage, which changes the flow characteristics, making it difficult for the traditional fixed-angle guide plate to continuously ensure smooth discharging.

[0005] In addition, desulfurizer particles are prone to moisture absorption, and the liquid bridge force generated between the particles can significantly enhance the adhesion of the material. At the outlet of the silo bottom, due to the static pressure of the upper material, it is easy to be compacted to form a stable material arch with high strength, which hinders the smooth entry of the material into the screw feeder and affects subsequent conveying. SUMMARY

[0006] The present application aims to provide an adjustable conveying device for desulfurizer production and a use method to solve the problems raised in the background art. To achieve the above-mentioned purpose, the present application provides the following technical scheme: an adjustable conveying device for desulfurizer production, comprising a mounting base, the top of the mounting base is rigidly connected with a silo, the discharge port at the bottom of the silo is connected with an external sleeve through a flange, and the internal sleeve is provided with a screw feeding component for quantitative conveying of materials, the top wall of the silo is provided with a feeding port, and the inside of the feeding port is provided with a V-shaped guide plate, the guide plate is used to receive and guide the desulfurizer to the feeding area of the screw feeding component, and the inner side wall of the silo is provided with an angle adjusting component, the angle adjusting component is connected with the guide plate and drives it to rotate to change the inclination angle.

[0007] Preferably, two sets of angle adjustment components are symmetrically arranged and are located on opposite sides of the inner wall of the hopper to jointly support the guide plate. A geared motor is fixedly installed on the outer wall of the hopper, and its output shaft extends into the hopper to drive the angle adjustment components on both sides to realize synchronous adjustment of the tilt angle of the guide plate.

[0008] Preferably, both angle adjustment components include mounting supports fixed to the inner wall of the hopper. The mounting supports have composite guide grooves. A drive arm is rotatably connected to the mounting supports. The drive arm is driven by the output shaft of the geared motor. The end of the drive arm away from the output shaft is hinged to a connecting rod. The other end of the connecting rod is hinged to a slider seat. The slider seat is equipped with a pair of guide bearings. The guide bearings are embedded in the composite guide groove and can roll along it. The outer end face of the slider seat is rigidly connected to the side wall of the guide plate.

[0009] Preferably, the composite guide groove comprises a main groove extending horizontally along the axial direction and an arc-shaped limiting groove at its end. A limiting pin is slidably installed on the inner side of the mounting support. One end of the limiting pin points towards the slider seat and is fixed with a wedge-shaped locking block. A return spring is sleeved on the limiting pin. The two ends of the return spring abut against the wedge-shaped locking block and the mounting support, respectively. Under the action of the return spring, the inclined surface of the wedge-shaped locking block continuously presses against the outer wall of the slider seat, locking the guide bearing on one side of it in the arc-shaped limiting groove.

[0010] Preferably, the slider seat is further provided with an arch-breaking component for treating the material accumulation at the bottom outlet of the hopper. The arch-breaking component includes a cavity opened inside the slider seat, in which a vibrating rod is provided. The vibrating rod is elastically supported in the cavity by a compression spring. One end of the vibrating rod extends out of the slider seat and is connected to an arch-breaking scraper. The arch-breaking scraper is slidably attached to the lower surface of the guide plate. The axial bottom surface of the main trough is provided with continuous wavy protrusions. The end of the vibrating rod is provided with a roller. The roller keeps in contact with the protrusions on the bottom surface of the main trough under the action of the compression spring.

[0011] Preferably, the screw feeding component includes a screw conveyor shaft that rotates within an outer sleeve via a bearing seat, a continuous screw blade is fixedly mounted on the screw conveyor shaft, and a drive motor is mounted on the outer side of the mounting base, the drive motor being connected to the end of the screw conveyor shaft via a transmission connection.

[0012] Preferably, the method of using the adjustable conveying device for desulfurizing agent production includes the following steps:

[0013] S1: Desulfurizing agent is added into the silo through the feeding port. The material falls onto the guide plate and is guided to the discharge port area.

[0014] S2: Based on the flow characteristics of the desulfurizing agent, the tilt angle of the guide plate is adjusted by the angle adjustment component to control the material feeding speed;

[0015] S3: When signs of blockage appear at the discharge port, the angle adjustment component controls the guide plate to enter the arch-breaking mode, and the arch-breaking component vibrates to break the material arch.

[0016] S4: The screw feeder delivers material quantitatively and continuously to the designated drop point.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In this invention, the desulfurizing agent is easily affected by changes in moisture content and bulk density during storage, which leads to changes in its flow characteristics. A guide plate with a fixed angle cannot continuously ensure smooth material feeding. By adjusting the tilt angle of the guide plate through the angle adjustment component, the operator can adapt to changes in the material state and accurately control the material feeding speed, thereby effectively solving the blockage problem.

[0019] In this invention, the change in the angle of the guide plate directly alters the cross-sectional shape and flow velocity of the material at the inlet of the screw feeder. For low-density dry desulfurizing agents with excessive fluidity, appropriately reducing the inclination angle can buffer and throttle the flow, preventing the material from becoming uncontrollable due to gravity flow and improving the metering accuracy and stability of the entire conveying system. In this invention, the roller at the end of the vibrating rod rolls along the wavy protrusion at the bottom of the main trough under the pressure of the compression spring, generating mechanical vibration. This vibration is transmitted to the arch-breaking scraper on the guide plate through the vibrating rod. Simultaneously, when the slider seat moves into the main trough within the arc-shaped limiting groove, the guide plate rotates downward during the adjustment process, allowing the arch-breaking scraper at its bottom to directly intervene and approach the material arch area. The vibration of the arch-breaking scraper breaks down the adhesion and static friction between material particles, causing the internal structure of the material arch to become unstable. As the slider seat drives the guide plate to move axially, the arch-breaking scraper directly scrapes and shears the loosened material arch, breaking down the blockage and allowing the desulfurizing agent to fall smoothly into the screw feeder to complete the conveying process.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 10This invention provides a technical solution: an adjustable conveying device for desulfurizing agent production, including a mounting base 1, a hopper 11 rigidly connected to the top of the mounting base 1, an outer sleeve 14 connected to the bottom outlet 12 of the hopper 11 via a flange, and a screw feeder 4 for quantitatively conveying materials housed inside the outer sleeve 14, a feeding port 13 opened on the top wall of the hopper 11, and a V-shaped guide plate 15 located below the feeding port 13 inside the hopper 11, the guide plate 15 is used to receive and guide the desulfurizing agent to the feeding area of ​​the screw feeder 4, and an angle adjustment component 2 is installed on the inner side wall of the hopper 11, the angle adjustment component 2 is connected to the guide plate 15 and drives it to rotate to change the tilt angle.

[0034] During operation, the desulfurizing agent is fed into the feed port 13 and falls onto the surface of the guide plate 15. The guide plate 15 uses its inclined surface to guide the material to flow towards the central discharge area, ensuring that the material enters the screw feeder 4. Since the desulfurizing agent is easily affected by changes in moisture content and bulk density during storage, its flow characteristics change. The guide plate 15 with a fixed angle cannot continuously ensure smooth material discharge. The angle adjustment component 2 adjusts the inclination angle of the guide plate 15, allowing the operator to adapt to changes in the material state and accurately control the material discharge speed, thereby effectively solving the blockage problem.

[0035] In this embodiment, two sets of angle adjustment components 2 are symmetrically arranged and are located on opposite sides of the inner wall of the hopper 11 to jointly support the guide plate 15. A geared motor 21 is fixedly installed on the outer wall of the hopper 11, and its output shaft extends into the hopper 11 and drives the angle adjustment components 2 on both sides to realize the synchronous adjustment of the tilt angle of the guide plate 15.

[0036] Both angle adjustment components 2 include mounting supports 22 fixed on the inner wall of the hopper 11. The mounting supports 22 are provided with composite guide grooves 23. A drive arm 24 is rotatably connected to the mounting supports 22. The drive arm 24 is connected to the output shaft of the geared motor 21. The end of the drive arm 24 away from the output shaft is hinged to a connecting rod 25. The other end of the connecting rod 25 is hinged to a slider seat 26. A pair of guide bearings 27 are mounted on the slider seat 26. The guide bearings 27 are embedded in the composite guide grooves 23 and can roll along them. The outer end face of the slider seat 26 is rigidly connected to the side wall of the guide plate 15.

[0037] The composite guide groove 23 comprises a main groove 231 extending horizontally along the axial direction and an arc-shaped limiting groove 232 located at its end. A limiting pin 28 is slidably installed inside the mounting support 22. One end of the limiting pin 28 points towards the slider seat 26 and is fixed with a wedge-shaped locking block 29. A return spring 210 is sleeved on the limiting pin 28. The two ends of the return spring 210 abut against the wedge-shaped locking block 29 and the mounting support 22, respectively. Under the action of the return spring 210, the inclined surface of the wedge-shaped locking block 29 continuously presses against the outer wall of the slider seat 26, locking the guide bearing 27 on one side of it in the arc-shaped limiting groove 232.

[0038] When it is necessary to adjust the tilt angle of the guide plate 15, the geared motor 21 is started, and the drive arm 24 rotates accordingly. The connecting rod 25 drives the slider seat 26 to move. At this time, the guide bearing 27 on one side of the slider seat 26 is constrained by the inner wall of the main groove 231 as a fulcrum, while the guide bearing 27 on the other side is pulled by the connecting rod 25 and generates an arc trajectory movement in the arc-shaped limiting groove 232. This causes the entire slider seat 26 together with the guide plate 15 to deflect around the fulcrum of the inner wall of the main groove 231, thereby realizing the adjustment of the tilt angle of the guide plate 15. Through the cooperation of the wedge-shaped locking block 29 and the return spring 210, when adjusting the tilt angle position of the guide plate 15, the angle change caused by material impact or vibration can be prevented.

[0039] The change in the angle of the guide plate 15 directly alters the cross-sectional shape and flow velocity of the material flow direction at the inlet of the screw feeder 4. For low-density dry desulfurizing agent with excessive fluidity, appropriately reducing the inclination angle can buffer and throttle the flow, preventing the material from being difficult to control due to gravity flow, and improving the metering accuracy and stability of the entire conveying system.

[0040] In this embodiment, the slider seat 26 is also provided with an arch-breaking component 3 for processing the material piled up at the bottom outlet 12 of the hopper 11. The arch-breaking component 3 includes a cavity 31 opened inside the slider seat 26. A vibrating rod 32 is provided in the cavity 31. The vibrating rod 32 is elastically supported in the cavity 31 by a compression spring 36. One end of the vibrating rod 32 extends out of the slider seat 26 and is connected to an arch-breaking scraper 33. The arch-breaking scraper 33 is slidably attached to the lower surface of the guide plate 15. The axial bottom surface of the main groove 231 is provided with a continuous wave-shaped protrusion 34. The end of the vibrating rod 32 is provided with a roller 35. The roller 35 keeps in contact with the protrusion 34 on the bottom surface of the main groove 231 under the action of the compression spring 36.

[0041] Due to its granular nature, the desulfurizing agent has high internal friction between particles and is prone to absorbing moisture, forming liquid bridge forces that increase viscosity. In the silo 11, the lower layer of material is subjected to the static pressure from the upper part and is easily compacted at the outlet of the silo 11 and the screw feeder 4, forming a high-strength stable material arch, which leads to flow interruption.

[0042] When signs of blockage appear at the discharge port 12 of the hopper 11, the operator can control the reduction motor 21 to drive the slider seat 26 from the arc-shaped limiting groove 232 area into the main groove 231 area and move it axially. At this time, the movement of the slider seat 26 causes the guide plate 15 to enter the arch-breaking mode. The roller 35 at the end of the vibrating rod 32 rolls along the wave-shaped protrusion 34 at the bottom of the main groove 231 under the pressure of the compression spring 36, generating mechanical vibration. This vibration is transmitted to the arch-breaking scraper 33 on the guide plate 15 through the vibrating rod 32, and at the same time, the slider seat 26... 6. When moving from the arc-shaped limiting groove 232 to the main groove 231, the guide plate 15 rotates downward during the adjustment process, so that the arch-breaking scraper 33 at its bottom can directly intervene and get close to the material arch area. The vibration of the arch-breaking scraper 33 breaks the adhesion and static friction between the material particles, causing the internal structure of the material arch to become unstable. As the slider seat 26 drives the guide plate 15 to move axially, the arch-breaking scraper 33 directly performs mechanical scraping and shearing on the loosened material arch, breaking up the blockage and allowing the desulfurizer to fall smoothly into the screw feeder 4 to complete the conveying.

[0043] In this embodiment, the spiral feeding component 4 includes a spiral conveying shaft 41 that rotates within the outer sleeve 14 via a bearing seat. A continuous spiral blade 42 is fixedly mounted on the spiral conveying shaft 41. A drive motor 43 is mounted on the outer side of the mounting base 1, and the drive motor 43 is connected to the end of the spiral conveying shaft 41 via a transmission connection.

[0044] During operation, the desulfurizing agent falls evenly from the discharge port 12 at the bottom of the silo 11 into the feeding section of the screw feeder 4. The screw conveyor shaft 41 is rotated by the drive motor 43, and the desulfurizing agent is stably and controllably transported to the designated drop point along the axial direction by the continuous pushing action of the screw blades 42.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
