Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a rotary dryer for gasified slag. Background Technology
[0002] Gasification slag is a solid waste produced after raw materials such as coal and biomass undergo gasification processes (such as coal gasification). A rotary dryer for gasification slag is a drying device specifically designed for processing gasification slag. Its core structure is an inclined, rotatable cylinder. The rotary dryer uses the rotation of the cylinder to fully disperse the material and has a large contact area with the heat medium, thus processing gasification slag with high moisture content and multiple components. Finally, the moisture is removed through heat conduction, convection, and radiation to obtain a dried gasification slag product.
[0003] The rotary dryer for gasification slag uses an inclined rotating cylinder that rotates slowly under the drive of a drive unit. High-moisture gasification slag enters from the high-end feed port of the cylinder and is continuously lifted and scattered by the lifting plates on the inner wall as the cylinder rotates. Under the action of gravity, it moves to the lower end. Then, the heat medium enters from one end of the cylinder and forms countercurrent or cocurrent contact with the material. Heat is transferred to the gasification slag through heat conduction, convection and radiation, causing the moisture to evaporate into water vapor and be discharged with the exhaust gas. Finally, the dried gasification slag is discharged from the low-end discharge port of the cylinder.
[0004] In existing technologies, some gasification slag rotary dryers encounter problems during operation due to the complex characteristics and high moisture content of the gasification slag itself. When it comes into contact with the feed inlet, it adheres to the inner wall of the feed inlet, and the accumulation gradually increases, causing blockage at the feed inlet and affecting the efficiency of the equipment. Therefore, a gasification slag rotary dryer is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a rotary dryer for gasified slag, which aims to improve the problem in some existing rotary dryers for gasified slag where gasified slag adheres to the inner wall of the feed inlet and accumulates, causing pipe blockage and affecting the drying efficiency of the equipment.

A support shaft is slidably connected to the inside of the sliding plate, and a drive assembly is fixedly connected to the front end of the support shaft. A limit shaft is fixedly connected to the bottom end of the sliding plate, and two limit rods are fixedly connected to the inside of the support plate. A return spring is sleeved on the outside of the limit rods. Two sliding shafts are fixedly connected to the rear end of the sliding plate, and a striking block is fixedly connected to the rear end of the two sliding shafts. As a further description of the above technical solution: The lubrication mechanism includes two fixed blocks, with a fixed bracket fixedly connected to the top of each fixed block. A storage box is fixedly connected inside the top of the fixed bracket, and a cover plate is fixedly connected to the top of the storage box.

A sliding rod is slidably connected inside the cover plate, and a rubber ring is fixedly connected to the bottom end of the sliding rod. A discharge pipe is fixedly connected to the bottom of the storage box. As a further description of the above technical solution: The drive assembly includes a drive motor, which is externally fixedly connected to the inside of the support plate, and a drive shaft is fixedly connected to the drive end of the drive motor. As a further description of the above technical solution: The support mechanism includes two support columns, a support frame is fixedly connected to the top of the support columns, multiple rotating wheels are fixedly connected to the top of the support base, a support ring is rotatably connected to the adjacent ends of the multiple rotating wheels, and a feed box is fixedly connected to the top of the support frame. As a further description of the above technical solution: The conveying mechanism includes a feeding pipe, which is fixedly connected to the outside of the support frame. A conveying motor is fixedly connected to the left end of the feeding pipe. A heat-conducting pipe is fixedly connected to the inside of the support frame. A auger rod is fixedly connected to the drive end of the conveying motor. A power motor is fixedly connected to the top front end of the support base. A drive gear is fixedly connected to the drive end of the power motor. A rotating box is rotatably connected to the outside of the feeding pipe. A driven gear is fixedly connected to the outside of the rotating box. A discharge port is provided at the front end of the support mechanism. As a further description of the above technical solution: The outer sides of the two limiting rods are slidably connected to the inside of the left and right ends of the sliding plate, respectively, and the rear ends of the two reset springs are fixedly connected to the front end of the sliding plate. As a further description of the above technical solution: The bottom end of the limiting shaft is slidably connected to the inside of the support shaft, and the outside of the two sliding shafts is slidably connected to the inside of the support plate.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the drive motor is started to drive the support shaft to rotate. The sliding plate is driven to reciprocate within the support plate by the cooperation of the sliding groove on the surface of the support shaft and the limiting shaft, and the return spring is squeezed. When the limiting shaft enters the vertical groove of the support shaft, the spring force of the return spring is released, causing the sliding plate to return to its original position. This causes the sliding shaft and the striking block to reciprocate to impact the feed box, breaking the tendency of material to accumulate in the feed box and avoiding blockage caused by material adhesion, clumping, etc. This ensures that the material enters the subsequent conveying stage stably, thereby improving the material processing efficiency.
[0008] 2. In this utility model, by pulling the sliding rod to slide inside the cover plate, the rubber ring is moved to control the flow of lubricant. During the sliding process, the sliding block squeezes the limiting spring to deform. After being released, the limiting spring resets, causing the sliding block to be embedded in the sliding rod for fixation. The lubricant drips onto the surface of the driving gear through the discharge pipe. Through meshing contact with the driven gear, the lubricant evenly covers the surfaces of the two gears, forming a lubricating film. This improves the stability and durability of the gear transmission structure, extends the service life of the entire equipment, and reduces equipment maintenance costs. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Example 1: Gasification slag rotary dryer, refer to Figure 1 , Figure 3 and Figure 4The system includes a support base 1, which provides stable support for the entire device and prevents displacement during use. A support mechanism 2 is located on the top of the support base 1, providing support to the support mechanism 2 and distributing the pressure on it, thereby improving its load-bearing capacity. The support mechanism 2 includes two support columns 21, with a support frame 22 fixedly connected to the top of each column. The support columns 21 provide positioning support for the support frame 22, preventing it from shifting or shaking during use. Multiple rotating wheels 23 are fixedly connected to the top of the support base 1, with support rings 24 rotatably connected to adjacent ends of each wheel 23. The wheels 23 are evenly distributed on the top of the support base 1, increasing their load-bearing capacity and providing rotational support for the support rings 24, thus improving the device's rotational efficiency. A support frame 3 is fixedly connected to the top right end of the support base 1. The support frame 3 is a supporting component, and the support base 1 and support frame 3 are welded together, improving the stability of the support frame 3. A support plate 4 is fixedly connected to the top of the support frame 3. The support plate 4 provides support, and the support frame 3 fixes the support plate 4, thereby improving the load-bearing stability of the support plate 4. A feed box 5 is fixedly connected to the top of the support frame 3. The feed box 5 provides a channel for raw materials to enter the equipment, and the support frame 3 fixes the feed box 5, thereby improving the stable conveying of the feed box 5. An anti-blocking mechanism 6 is provided inside the support plate 4. The support plate 4 fixes the anti-blocking mechanism 6 to prevent the anti-blocking mechanism 6 from shifting during operation, thereby improving the operational stability of the anti-blocking mechanism 6. The support frame 3 houses a conveying mechanism 7, which provides support to the conveying mechanism 7, preventing it from shaking during operation and thus improving its stable operation. A lubrication mechanism 8 is located at the top front end of the support base 1, providing lubrication to extend the equipment's lifespan. The anti-blocking mechanism 6 includes a sliding plate 63, which is externally slidably connected to the inside of the support plate 4. The support plate 4 provides sliding guidance for the sliding plate 63, thereby improving its sliding stability. A support shaft 62 is slidably connected internally to the sliding plate 63, and a drive assembly 61 is fixedly connected to the front end of the support shaft 62. Activating the drive assembly 61 rotates the support shaft 62, causing the sliding plate 63 to slide within the support plate 4. The drive assembly 61 includes a transmission motor 611, which is externally fixedly connected to the inside of the support plate 4. The support plate 4 provides fixation for the transmission motor 611, preventing it from shaking during operation and thus improving its operational stability. The drive end of the transmission motor 611 is fixedly connected to the drive shaft 612. By starting the transmission motor 611, the drive force is provided to rotate the drive shaft 612, thereby causing the drive shaft 612 to rotate. A limiting shaft 64 is fixedly connected to the bottom end of the sliding plate 63. The bottom end of the limiting shaft 64 is slidably connected inside the support shaft 62. The rotation of the drive shaft 612 drives the support shaft 62 to rotate. A groove is provided on the outside of the support shaft 62 to guide the sliding of the limiting shaft 64. The limiting shaft 64 is welded to the sliding plate 63. With the rotation of the support shaft 62, the sliding plate 63 slides outside the support shaft 62 via the limiting shaft 64. Two limiting rods 65 are fixedly connected inside the support plate 4. The two limiting rods 65 are slidably connected to the left and right ends of the sliding plate 63, respectively. The support plate 4 provides fixation for the limiting rods 65, and the limiting rods 65 provide guidance for the sliding of the sliding plate 63, thereby preventing the sliding plate 63 from deviating during sliding. A return spring 66 is sleeved on the outside of the limiting rods 65. The limiting rods 65 provide support for the return spring 66, so that the return spring 66 is evenly stressed, improving the efficiency of the return spring 66. The rear ends of two return springs 66 are fixedly connected to the front end of the sliding plate 63. The sliding plate 63 compresses the return springs 66, causing them to deform under force. Two sliding shafts 67 are fixedly connected to the rear end of the sliding plate 63. When the limiting shaft 64 slides outside the support shaft 62 and encounters a vertical groove, the return springs 66 release their elastic force, causing the sliding plate 63 to move along the sliding shafts 67 under the action of the limiting shaft 64. The two sliding shafts 67 are externally slidably connected to the inside of the support plate 4. The support plate 4 provides guidance for the sliding of the sliding shafts 67, thus ensuring the stability of the sliding. A striking block 68 is fixedly connected to the rear end of the two sliding shafts 67. The sliding of the sliding shafts 67 causes the striking block 68 to slide, resulting in the striking block 68 continuously striking the feed box 5, causing the feed box 5 to vibrate and preventing raw material accumulation and blockage of the pipeline. Specifically, by starting the transmission motor 611 to drive the drive shaft 612 to rotate, the support shaft 62 will rotate. Through the sliding groove on the surface of the support shaft 62, the sliding plate 63 will slide outside the two limit bars 65 under the action of the limit shaft 64. The sliding plate 63 will compress the return spring 66. When the limit shaft 64 encounters the vertical sliding groove on the surface of the support shaft 62, the return spring 66 will release its elastic force, causing the sliding plate 63 to slide inside the support plate 4, thereby driving the sliding shaft 67 to slide, and then driving the striking block 68 to reciprocate to strike the feed box 5.
[0013] Reference Figure 1 , Figure 3 and Figure 5The lubrication mechanism 8 includes two fixed blocks 81, with fixed brackets 82 fixedly connected to the top of each block 81. The fixed brackets 82 provide support, and the fixed blocks 81 are welded to the fixed brackets 82, thereby improving the load-bearing stability of the fixed brackets 82. A storage tank 83 is fixedly connected inside the top of the fixed brackets 82, storing lubricating oil. The fixed brackets 82 provide support for the storage tank 83, thus improving its loading capacity. A cover plate 84 is fixedly connected to the top of the storage tank 83, providing stable support. A feed hole is provided on the top of the cover plate 84. Limiting springs 85 are fixedly connected to both the left and right ends of the cover plate 84. The cover plate 84 has grooves inside, providing stable support for the two limiting springs 85, thereby improving their efficiency. Two limiting springs 85 are each connected to a sliding block 86 at their adjacent ends. The two sliding blocks 86 are slidably connected to the inside of a cover plate 84. The cover plate 84 has grooves inside to guide the sliding of the two sliding blocks 86 and improve their sliding stability. A sliding rod 87 is slidably connected inside the cover plate 84. The adjacent ends of the two sliding blocks 86 are slidably connected to the left and right ends of the sliding rod 87, respectively. The cover plate 84 provides support for the sliding of the sliding rod 87. The sliding rod 87 has multiple grooves on its exterior. By sliding the sliding rod 87, it presses against the sliding blocks 86, causing the sliding blocks 86 to embed into the interior of the sliding rod 87. These grooves are used to adjust the amount of lubricant, thus adapting to different equipment rotation efficiencies. A rubber ring 88 is fixedly connected to the bottom end of the sliding rod 87 to limit the amount of lubricant entering and exiting. The bottom of the storage tank 83 is fixedly connected to the discharge pipe 89, which guides the lubricant to flow accurately to the parts that need lubrication. Specifically, by pulling the sliding rod 87, the sliding rod 87 slides inside the cover plate 84, thereby squeezing the two sliding blocks 86. The sliding blocks 86 squeeze the limiting spring 85, and the limiting spring 85 releases its elastic force, causing the sliding blocks 86 to embed into the groove inside the sliding rod 87, thus fixing the sliding rod 87. Through the cooperation of the sliding blocks 86 and the multiple grooves inside the sliding rod 87, the flow rate of the lubricant is adjusted, thereby improving the efficiency of the equipment.
[0014] Reference Figure 1 and Figure 2The conveying mechanism 7 includes a feeding pipe 71, which is externally and fixedly connected to the inside of the support frame 3. The feeding pipe 71 provides a guide for material conveying, and the support frame 3 provides fixation for the feeding pipe 71, thereby improving its load-bearing capacity. A conveying motor 72 is fixedly connected to the left end of the feeding pipe 71, providing support for the conveying motor 72 and preventing it from shifting during operation, thus improving its stability. A heat-conducting pipe 73 is fixedly connected inside the support frame 3, providing a heat conveying channel for drying the material. A auger rod 74 is fixedly connected to the drive end of the conveying motor 72. By starting the conveying motor 72, the motor drives the auger rod 74 to rotate, thereby conveying the material. A power motor 75 is fixedly connected to the top front end of the support base 1, providing support for the power motor 75 and improving its operational stability. A drive gear 76 is fixedly connected to the drive end of the power motor 75. Starting the power motor 75 provides driving force for the rotation of the drive gear 76, thereby causing the drive gear 76 to rotate. A rotating box 78 is rotatably connected to the outside of the feeding pipe 71. A driven gear 77 is fixedly connected to the outside of the rotating box 78. The driven gear 77 meshes with the drive gear 76. When the drive gear 76 rotates, the driven gear 77 rotates accordingly, thereby causing the rotating box 78 to rotate. A discharge port 9 is provided at the front end of the support mechanism 2. The dried gasified slag is finally discharged from the equipment through the discharge port 9. Specifically, the drive gear 76 is driven to rotate by starting the power motor 75, which in turn drives the driven gear 77 to rotate, thereby driving the rotating box 78 to rotate. At this time, the auger rod 74 is driven to rotate by starting the transmission motor 72, thereby conveying the material and heating and drying the material through the heat pipe 73.
[0015] The implementation principle of this application embodiment is as follows: Material is conveyed through the feed box 5. The drive motor 611 is started, driving the drive shaft 612 to rotate. This drives the support shaft 62 to rotate. The groove on the surface of the support shaft 62 causes the limiting shaft 64 to drive the sliding plate 63 to reciprocate within the support plate 4. The sliding plate 63 compresses the return spring 66. When the limiting shaft 64 encounters the vertical groove on the outside of the support shaft 62, the return spring 66 releases its elastic force, causing the sliding plate 63 to reset. This, in turn, drives the sliding shaft 67 within the support plate 4. The material slides inside the rotating box 78, and the sliding shaft 67 drives the striking block 68 to reciprocate and impact the feed box 5 to prevent material accumulation and blockage. At the same time, the conveyor motor 72 is started to drive the auger rod 74 to rotate, so that the material enters the interior of the rotating box 78. At this time, the power motor 75 is started to drive the drive gear 76 to rotate, which in turn drives the driven gear 77 to rotate, and then drives the rotating box 78 to rotate. Under the action of the heat pipe 73, the material is dried, and the dried material is discharged through the discharge port 9. By sliding the sliding roller 87 inside the cover plate 84, the rubber ring 88 is moved, thereby controlling the flow of lubricant. The sliding roller 87 presses the sliding block 86, causing the sliding block 86 to compress the limiting spring 85 and deform. Then, the limiting spring 85 releases its elasticity, causing the sliding block 86 to return to its original position and embed itself inside the sliding roller 87, thus fixing the sliding roller 87. Finally, the lubricant falls onto the surface of the drive gear 76 through the discharge pipe 89. Through the contact between the drive gear 76 and the driven gear 77, the surfaces of the drive gear 76 and the driven gear 77 are covered with lubricant, thereby improving the service life of the equipment.
