Description

Technical Field

[0001] This utility model relates to the technical field of in-furnace calcium injection desulfurization systems, and in particular to an auxiliary device for an in-furnace unblocking structure and limestone buffer silo. Background Technology

[0002] Fossil fuels such as coal and oil produce large amounts of sulfur dioxide during combustion. and nitrogen oxides Waste gases emitted without treatment can cause serious environmental damage if released directly. To effectively reduce these harmful emissions, desulfurization and denitrification processes are commonly used in industry, employing chemical or physical methods to remove these gases from waste gases. and This removes pollutants, thereby reducing pollution to the atmospheric environment.

[0003] Among numerous desulfurization technologies, in-furnace calcium injection desulfurization is a common method. When an in-furnace calcium injection desulfurization system is operating, purchased limestone powder needs to be transported to a limestone silo. For example... Figure 1 As shown, the limestone silo is assembled from components such as a limestone storage tank, a buffer silo, and a discharge port, connected by flanges. Limestone powder enters the storage tank and is discharged through the limestone buffer silo. However, during operation, the limestone buffer silo often becomes damp, leading to limestone caking and subsequent empty silo or blockage. Because the limestone silo is a single unit, cleaning the buffer silo requires disassembling some components for unblocking, which is not only time-consuming and labor-intensive but also causes intermittent stops in the conveying operation, impacting the overall system operation. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide an auxiliary device for furnace unblocking structure and limestone buffer silo that reduces disassembly and maintenance and ensures continuous conveying.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A furnace inlet unblocking structure includes a drive mechanism, a rotating assembly, a reversing assembly, and a striking assembly. The drive mechanism includes a drive motor and a drive shaft, the drive shaft being horizontally positioned and one end connected to the output shaft of the drive motor. The rotating assembly includes a rotating rod and blades, the rotating rod being vertically positioned and one end of the blades being fixed to the rotating rod. The reversing assembly is drively connected to the drive mechanism and the rotating assembly, transmitting the power of the drive mechanism to the rotating assembly. The striking assembly includes a magnetic striking element and a magnetic mating element, the magnetic striking element being elastically positioned, the magnetic mating element being fixedly connected to the rotating rod, and the magnetic striking element and the magnetic mating element being on the same horizontal plane.

[0007] Furthermore, the reversing assembly includes a sheath, a first bevel gear, and a second bevel gear. Both the first and second bevel gears are located inside the sheath and mesh with each other. One end of the drive shaft extends through one side wall of the sheath into the interior of the sheath, and one end of the rotating rod extends through both side walls of the sheath into the exterior of the sheath. The first bevel gear is coaxially and fixedly connected to the drive shaft, and the second bevel gear is coaxially and fixedly connected to the rotating rod.

[0008] Furthermore, the reversing assembly also includes multiple sealed bearings, with the drive shaft and rotor rotatably connected to the sheath via the sealed bearings.

[0009] Furthermore, the blades are spirally distributed on the rotating rod, and the blade surface is provided with protrusions.

[0010] Furthermore, the striking assembly also includes a fixed ring and an elastic element. The magnetic striking element is disposed inside the fixed ring and is elastically connected to the inner wall of the fixed ring through the elastic element. The magnetic mating element is fixed to the rotating rod through a connecting rod.

[0011] Furthermore, the striking assembly also includes a guide rod, which is located inside the elastic element and slidably connected to the fixing ring. One end of the guide rod is fixedly connected to the magnetic striking element, and the other end extends through the fixing ring to the outside.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0023] like Figures 2 to 3As shown, this utility model discloses a furnace-mounted unblocking structure, comprising a drive mechanism 1, a rotating assembly 2, a reversing assembly 3, and a striking assembly 4. The drive mechanism 1 includes a drive motor 11 and a drive shaft 12. The drive motor 11 can be selected from different power and speed models, such as a three-phase asynchronous motor or a servo motor, to provide continuous and stable power output for the entire unblocking structure, depending on actual working conditions. The drive shaft 12 is horizontally positioned, with one end rigidly connected to the output shaft of the drive motor 11 via a coupling to ensure the stability and reliability of power transmission and reduce energy loss during power transmission. The rotating assembly 2 includes a rotating rod 21 and blades 22. The rotating rod 21 is vertically positioned and can be made of highly corrosion-resistant stainless steel to adapt to the working environment of the limestone silo, preventing rust due to moisture and extending its service life. One end of the blades 22 is fixed to the rotating rod 21 by welding or connecting parts, and can rotate synchronously with the rotating rod 21. The reversing assembly 3 is connected to the drive mechanism 1 and the rotating assembly 2, transmitting the power of the drive mechanism 1 to the rotating assembly 2. The striking assembly 4 includes a magnetic striking element 41 and a magnetic mating element 42. The magnetic striking element 41 is elastically set and can be made of permanent magnet material, such as neodymium iron boron permanent magnets, which have high magnetic strength. The magnetic mating element 42 is fixedly connected to the rotating rod 21 and is also made of permanent magnet material. It can rotate synchronously with the rotating rod 21, and the two are on the same horizontal plane with the same relative magnetic poles. During operation, the drive motor 11 drives the drive shaft 12 to rotate, and the horizontal power is converted into the vertical rotational force of the rotating assembly by the reversing assembly 3, causing the vertically set rotating rod 21 and the blade 22 fixed on it to rotate, realizing the stirring action. At the same time, the magnetic mating element 42 fixed on the rotating rod 21 rotates with it. The magnetic repulsion force of the same magnetic poles makes the elastically set magnetic striking element 41 and magnetic mating element 42 periodically move away and closer, producing a striking action. Through the dual action of mechanical stirring and magnetic striking, the limestone powder is prevented from getting damp and caking, which could lead to empty chambers or blockages.

[0024] like Figure 4As shown, the reversing assembly 3 includes a sheath 31, a first bevel gear 32, and a second bevel gear 33. Both the first bevel gear 32 and the second bevel gear 33 are located inside the sheath 31 and mesh with each other, forming a gear transmission structure. One end of the drive shaft 12 extends through one side wall of the sheath 31 into the interior of the sheath 31, and one end of the rotating rod 21 extends through both side walls of the sheath 31 into the outside of the sheath 31. The first bevel gear 32 is coaxially and fixedly connected to the drive shaft 12, and the second bevel gear 33 is coaxially and fixedly connected to the rotating rod 21. When the drive shaft 12 rotates, it drives the first bevel gear 32 to rotate synchronously, and through meshing, drives the second bevel gear 33 to rotate, thereby realizing the rotation of the rotating rod 21 and completing the power transmission from the drive mechanism 1 to the rotating assembly 2. Gear transmission has the characteristics of accurate transmission ratio and high transmission efficiency, ensuring that the rotating assembly 2 operates at a stable speed and torque, enabling the blade 22, the magnetic striking element 41, and the magnetic mating element 42 to operate continuously and stably.

[0025] The reversing assembly 3 also includes multiple sealed bearings 34, through which the drive shaft 12 and the rotating rod 21 are rotatably connected to the sheath 31. The sealed bearings 34, in conjunction with the sheath 31, provide a sealing effect, isolating dust, limestone powder, and other impurities from entering the interior, ensuring a clean environment for gear transmission, improving transmission efficiency, and extending the equipment's service life. Simultaneously, they provide support, restricting radial and axial movement of the shaft and maintaining the coaxiality and stability of the shaft rotation.

[0026] like Figure 3 As shown, to further enhance the stirring effect, the blades 22 are spirally distributed on the rotating rod 21. When rotating, they generate a spiral pushing effect on the limestone powder, which is beneficial for conveying and flowing. At the same time, the surface of the blades 22 is provided with protrusions 221, which can be hemispherical, conical, or other convex shapes. These protrusions are integrally formed by casting or welded to the surface of the blades 22, increasing the contact area and friction between the blades 22 and the limestone powder, and enhancing the stirring force.

[0027] The striking assembly 4 also includes a fixed ring 43 and an elastic element 44. The magnetic striking element 41 is disposed inside the fixed ring 43 and elastically connected to the inner wall of the fixed ring 43 via the elastic element 44. The elastic element 44 can be a spring or a rubber elastomer, allowing the magnetic striking element 41 to move freely within a certain range and reset due to elastic deformation. The magnetic mating element 42 is fixed to the rotating rod 21 via a connecting rod 45. When the rotating rod 21 rotates, it can drive the magnetic mating element 42 to rotate. It can be understood that multiple sets of magnetic striking elements 41 and mating elastic elements 44 can be configured and evenly distributed in a ring shape inside the fixed ring 43 to expand the striking range.

[0028] The striking assembly 4 also includes a guide rod 46, which is located inside the elastic member 44 and slidably connected to the fixing ring 43. One end of the guide rod 46 is fixedly connected to the magnetic striking member 41, and the other end extends outward through the fixing ring 43. The guide rod 46 guides the movement of the magnetic striking member 41, ensuring that the movement direction of the magnetic striking member 41 under the action of the elastic member 44 is accurate and avoiding deviation.

[0029] The connecting rod 45 has a triangular prism structure with the edges facing upwards. While ensuring connection strength, it can reduce the contact area with limestone powder, reduce the accumulation and adhesion of limestone powder on the connecting rod 45, and help keep the connecting rod 45 clean and operate normally.

[0030] A limestone buffer silo auxiliary device includes a limestone buffer silo 5 and the aforementioned unblocking structure. The limestone buffer silo 5 includes a conical body 51 and a columnar connecting section 52 constructed at its bottom. The design of the conical body 51 facilitates the flow of limestone powder to the bottom under gravity. A support member 53 is provided on the outer wall of the body 51, which can be welded from angle steel or channel steel and has a triangular, rectangular, or other structural form to ensure support strength. A drive motor 11 is mounted on the support member 53, and a drive shaft 12 extends through the side wall of the body 51 into its interior. The drive shaft 12 is coaxially arranged with the limestone buffer silo 5, and its length and the distribution range of the blades 22 correspond to the height of the limestone buffer silo 5 to ensure that the limestone powder can be fully stirred. The rotating component 2 and the reversing component 3 are both installed inside the body 51, and power transmission, stirring, and pushing actions are completed inside. A magnetic mating component 42 is installed inside the connecting section 52, and a magnetic striking component 41 is installed outside the connecting section 52. The two interact magnetically to achieve unblocking at the connecting section 52 through striking. Understandably, the length of the connecting rod 45 corresponds to the inner diameter of the connecting section 52, ensuring that the relative distance between the magnetic striking element 41 and the magnetic mating element 42 is within the effective range of magnetic action, thus generating an effective repulsive reaction. In actual use, the drive motor 11 is started, and the drive shaft 12 rotates. The horizontal power is converted into vertical power by the reversing component 3, driving the rotating rod 21 and the blade 22 to rotate, agitating the limestone powder in the limestone buffer chamber 5 to prevent caking. The rotation of the rotating rod 21 drives the magnetic mating element 42 to rotate. When the magnetic mating element 42 approaches the magnetic striking element 41, the magnetic attraction causes the magnetic striking element 41 to overcome the elastic force of the elastic element 44 and move towards the magnetic mating element 42. When they miss each other, the magnetic force disappears, and the magnetic striking element 41 resets under the action of the elastic element 44, striking the outer wall of the connecting section 52 to further clear blockages and ensure the smooth transport of limestone powder.
