Description

Technical Field

[0001] This utility model relates to the technical field of slag discharge equipment, specifically a scale bucket type dry slag discharge machine. Background Technology

[0002] The scale-bucket type dry slag discharge machine is a key piece of equipment for processing high-temperature slag from coal-fired boilers. Its working principle involves the slow conveying of high-temperature slag via heat-resistant scale-bucket chain plates. Simultaneously, the negative pressure environment created inside the equipment guides cold air to penetrate the slag layer in the opposite direction for thorough heat exchange, achieving slag cooling and waste heat recovery. The equipment mainly consists of a sealed shell, a scale-bucket chain plate conveying system, a roller support mechanism, and a head drive section. The head drive section, as the power core, includes a drive motor, small sprockets, a transmission chain, and a large sprocket. Power is transmitted to the internal drive sprockets via chain drive, driving the scale-bucket chain plates continuously.

[0003] In existing technologies, the head drive section of a bucket-type dry slag remover is constantly exposed to the external environment. During operation, the slag remover continuously generates a large amount of fine dust, and the surfaces of the large and small sprockets and drive chains require lubrication to ensure transmission efficiency. Dust easily adheres to the lubricated surfaces of these exposed transmission components. Over time, the mixture of dust and lubricating oil deposits leads to lubrication failure in transmission components, increased operating resistance, transmission jamming, and accelerated corrosion of metal parts. These problems force frequent shutdowns for cleaning and maintenance, severely reducing the continuous operating efficiency and processing stability of the production system. Therefore, this invention proposes a bucket-type dry slag remover to solve these problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a scale bucket type dry slag discharge machine, comprising: a feeder housing 1, which covers the outside of the feeding steel belt to prevent material from flying out and ensure that the internal material is in full contact with cold air; a frequency-modulated motor 2 is fixedly installed on one side of the top of the feeder housing 1, and the output end of the frequency-modulated motor 2 is fixedly connected to a small sprocket 3; a large sprocket 4 is provided below the small sprocket 3, and the large sprocket 4 is fixedly connected to one end of a drive shaft; the other end of the drive shaft is fixedly connected to a drive sprocket inside the feeder housing 1; and the rotation of the drive sprocket drives the material to move freely. The high-temperature resistant chain moves, thereby driving the scale bucket to operate. The small sprocket 3 and the large sprocket 4 are driven by the meshing of the chain 5. A fixed cover 6 is provided on one side of the small sprocket 3 and the large sprocket 4, and a movable cover 7 is provided on the other side of the small sprocket 3 and the large sprocket 4. One side of the movable cover 7 is slidably inserted into one side of the fixed cover 6. The fixed cover 6 has a groove that is fitted into the movable cover 7. The other side of the fixed cover 6 is fixedly connected to the feeder housing 1. A cross pressure frame 8 is abutted on the other side of the movable cover 7. The cross pressure frame 8 and the feeder housing 1 are detachably connected by a limiting component.

[0024] In use, the fixed cover 6 is fixedly connected to the side wall of the feeder housing 1. When it is necessary to protect the small sprocket 3, the large sprocket 4 and the chain 5, the movable cover 7 is placed on one side of the fixed cover 6 and the two are inserted together. Then, the cross pressure frame 8 is pressed onto the outer wall of the movable cover 7. Then, the movable cover 7 is limited and fixed outside the fixed cover 6 by the limiting component, thus forming protection for the small sprocket 3, the large sprocket 4 and the chain 5, avoiding the adhesion of slag and dust, and reducing the trouble of frequent shutdowns for cleaning. At this time, the frequency modulation motor 2 can be started to drive the small sprocket 3 to move. Under the meshing action of the chain 5, the large sprocket 4 is driven to rotate. The large sprocket 4 drives the transmission shaft fixedly sleeved inside to rotate. The transmission shaft is fixedly connected to the drive sprocket inside the feeder housing 1. Through the rotation of the drive sprocket, the high-temperature resistant chain is driven to move, and finally the scale bucket is operated, thereby realizing slag discharge and feeding.

[0025] The bottom of the frequency-modulated motor 2 is fixedly connected to the upper surface of the fixed base 9, and the lower surface of the fixed base 9 is fixedly connected to the outer wall of the feeder housing 1. The fixed base 9 fixes the frequency-modulated motor 2. A frequency converter 10 is fixedly installed on one side wall of the fixed base 9. The frequency converter 10 is electrically connected to the frequency-modulated motor 2. By operating the frequency converter 10, the speed of the frequency-modulated motor 2 can be adjusted, thereby adjusting the speed of the large and small sprockets and thus adjusting the running speed of the conveyor belt. A guide box 11 is fixedly connected to the lower surface of the top side of the feeder housing 1, and a frame 12 is installed on one side of the guide box 11. The frame 12 is fixedly connected to the guide box 11 and the feeder housing 1. A dust cover 15 is detachably installed on the movable cover 7 by bolts. The frame 12 further fixes and supports the feeder housing 1 to ensure stability. The guide box 11 guides the material, which is transported from the slag well inside the feeder housing 1 to the crusher. The dust cover 15 is detachably installed on the movable cover 7, which facilitates heat dissipation of the large and small sprockets and chain 5, and prevents slag and dust from entering the movable cover 7 and the fixed cover 6. It also facilitates subsequent disassembly and cleaning.

[0026] The movable cover 7 has several positioning grooves 13 on the side wall away from the feeder housing 1. The positioning grooves 13 are slidably inserted into one end of the positioning column 14, and the other end of the positioning column 14 is fixedly connected to the cross pressure frame 8. The slidable insertion of the positioning column 14 and the positioning groove 13 facilitates the quick positioning and installation of the cross pressure frame 8. The side wall of the cross pressure frame 8 that abuts against the feeder housing 1 has a limiting groove 16. The limiting component includes a limiting plate 17, which is fixedly connected to the feeder housing 1. A limiting rod 18 is slidably sleeved inside the limiting plate 17. The limiting plate 17 performs limiting. One end of the limiting rod 18 is slidably inserted into the limiting groove 16, and the other end of the limiting rod 18 is fixedly connected to the pull plate 19. The pull plate 19 and the limiting plate 17 are fixedly connected by a spring 20.

[0027] When the movable cover 7 is inserted into the fixed cover 6, to ensure the stability of the movable cover 7, the two pull plates 19 are pulled in opposite directions first, causing the tension spring 20 to slide under the limit of the limit plate 17, moving away from the movable cover 7. At this time, the cross pressure frame 8 is inserted through the sliding connection of the positioning post 14 and the positioning groove 13, so that the cross pressure frame 8 is initially pressed onto the movable cover 7 and abuts against the side wall of the feeder housing 1. Then, by releasing the pull plate 19, under the reverse elastic force of the spring 20, the limit rod 18 moves back and inserts into the limit groove 16 opened at the end of the cross pressure frame 8, thereby limiting and fixing the cross pressure frame 8. Then, the movable cover 7 is limited and fixed by the limiting and fixing of the cross pressure frame 8, and finally the movable cover 7 is stably inserted into the fixed cover 6, avoiding the risk of the movable cover 7 falling off. In addition, when it is necessary to disassemble the movable cover 7, the two pull plates 19 are pulled in opposite directions again.

[0028] A sealing strip 21 is fixedly connected to the contact side of the fixed cover 6 and the movable cover 7. The sealing strip 21 is slidably inserted into the sealing sleeve 22 fixedly connected to the movable cover 7. A guide tube 23 is fixedly sleeved on the top side of the movable cover 7. A sealing plug 24 is threaded onto the top of the guide tube 23. During the insertion process of the fixed cover 6 and the movable cover 7, the sealing sleeve 22 on the movable cover 7 is inserted into the sealing strip 21, thereby forming a seal at the edge of the fixed cover 6 and the movable cover 7, further preventing the entry of slag and dust. In addition, the guide tube 23 installed on the top of the movable cover 7 can be disassembled to allow lubricating oil to be poured in under the guiding action of the guide tube 23, thereby avoiding the trouble of disassembling the movable cover 7 for lubrication.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
