Description

Technical Field

[0001] This utility model relates to the field of slag discharge machine technology, and in particular to an air-circulating, air-cooled, dry slag discharge machine. Background Technology

[0002] With the rapid advancement of social industrialization, coal-fired power generation has become one of the mainstream methods. However, the waste residue generated during boiler combustion needs to be treated in a timely manner. Especially in arid areas, where water resources are scarce, air-cooled dry ash removal machines have become key equipment. As a special device for treating waste residue from pulverized coal boilers, this equipment can achieve the cooling and transportation of boiler waste residue without any water consumption.

[0003] However, there are obvious shortcomings in the existing technology: a large amount of boiler slag enters the cooling channel in a short period of time, resulting in an excessively thick accumulation of slag in the channel. Air cannot quickly penetrate and remove the heat inside the slag, which not only reduces the overall cooling effect of the slag, but also results in low utilization of the heat contained in the slag. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an air-circulating, air-cooled, dry slag discharge machine, which enhances the overall cooling effect of waste slag and improves the utilization rate of the heat contained in the waste slag.

[0005] To solve the above technical problems, the present invention provides a technical solution: an air-circulating, air-cooled, dry ash removal machine, comprising: two conveyor belt devices and a transition shell connected to the bottom of the boiler, wherein air-cooled ash removal mechanisms are respectively connected to the bottom ends of the transition shell, and the conveyor belt devices are respectively provided below the air-cooled ash removal mechanisms. The air-cooled slag discharge mechanism includes an inclined air-cooled slag discharge machine assembly. A constant feed box assembly is connected between the upper inclined end of the air-cooled slag discharge machine assembly and the transition shell. A discharge pipe is connected to the lower inclined end of the air-cooled slag discharge machine assembly. The width of the air-cooled slag discharge machine assembly is greater than the width of the constant feed box assembly and the width of the discharge pipe, respectively. The air-cooled inspection machine assembly includes a rectangular cooling box, the top of which is open and covered with a heat-absorbing cover. A spreading spiral blade is inserted through the upper oblique end of the rectangular cooling box, and a collecting spiral blade is inserted through the lower oblique end of the rectangular cooling box. A material-turning rod assembly is installed inside the rectangular cooling box. It also includes an air intake system that separately supplies air to the air-cooled inspection unit components.

[0006] By adopting the above technical solution, during operation, the waste slag inside the boiler falls into the transition shell. The constant feed box assembly evenly transports the waste slag from the transition shell to the interior of the rectangular cooling box, where the thickness of the transported waste slag is relatively large. Since the width of the air-cooled sorting machine assembly is greater than the width of the constant feed box assembly, the spreading spiral blades activate and spirally spread the waste slag towards both ends, reducing the thickness of the waste slag. Subsequently, the heat-absorbing cover works to absorb the heat contained in the waste slag. During this process, the turning rod assembly operates synchronously to turn the waste slag, flipping the waste slag in contact with the rectangular cooling box to the upper layer, facilitating heat dissipation and absorption, effectively improving heat dissipation efficiency. Simultaneously, the rectangular cooling box maintains a negative pressure state, and the air intake system guides external low-temperature gas into the box, further cooling the waste slag. When the waste slag temperature drops to the target value, the collecting spiral blades spirally gather the waste slag distributed along the width of the rectangular cooling box towards the center, allowing the waste slag to slide smoothly out of the discharge pipe and finally fall onto the corresponding conveyor belt device to complete the transport.

[0007] In a preferred embodiment, the present invention can be further configured as follows: the constant feed box assembly includes a feed box and a feed rod passing through its inner cavity; the upper inclined end of the feed box is connected to the transition shell, and the lower inclined end is connected to the air-cooled inspection machine assembly; the feed rod includes a first rotating shaft; a plurality of scraping blades are spaced apart on the outer circle of the first rotating shaft; both ends of the first rotating shaft pass through the side wall of the feed box and are rotatably connected; and one end of the first rotating shaft is connected to a first motor.

[0008] By adopting the above technical solution, the first motor drives the first rotating shaft to rotate at a uniform speed in a circle. The first rotating shaft drives the scraper blade to rotate in a circle along its axis. The scraper blade scrapes the waste residue in the transition shell, so that the waste residue can enter the rectangular cooling box of the air-cooled inspection machine component evenly and smoothly, reducing the probability of blockage at the outlet of the transition shell.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the heat-absorbing cover includes a rectangular shell, an exhaust pipe is connected to the upper surface of the rectangular shell, a plurality of air intake holes are spaced apart on the lower surface of the rectangular shell, and a rectangular metal filter screen is also included covering the lower surface of the rectangular shell. The rectangular shell is connected to the top opening of the rectangular cooling box, an air supply pipe is connected to the outer end of the exhaust pipe, the end of the air supply pipe away from the exhaust pipe is connected to the external boiler air inlet, and a high-temperature resistant air pump is provided on the air supply pipe.

[0010] By employing the above technical solution, the high-temperature resistant vacuum pump draws gas from the rectangular shell, creating a negative pressure state within the shell. This negative pressure then draws away heat from the rectangular cooling box through several suction holes, achieving the purpose of cooling. The rectangular metal filter screen prevents dust from the waste residue from clogging the suction holes, enhancing the stability of the cooling process.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the spreading spiral blade component includes a second rotating shaft, the outer circles of the two ends of the second rotating shaft are respectively connected to a first left spiral blade and a first right spiral blade, both ends of the second rotating shaft pass through the side wall of the rectangular cooling box and are rotatably connected, and one end of the second rotating shaft is connected to a second motor.

[0012] By adopting the above technical solution, the second motor drives the second rotating shaft to rotate, and the second rotating shaft drives the first left helical blade and the first right helical blade to rotate in a circle. The first left helical blade and the first right helical blade spread the flat waste residue to the front and rear ends, thereby reducing the thickness of the waste residue.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the collecting spiral blade includes a third rotating shaft, the outer circles of the two ends of the third rotating shaft are respectively connected to a second left spiral blade and a second right spiral blade, both ends of the third rotating shaft pass through the side wall of the rectangular cooling box and are rotatably connected, and one end of the third rotating shaft is connected to a third motor.

[0014] By adopting the above technical solution, the third motor drives the third rotating shaft to rotate, and the third rotating shaft drives the second left spiral blade and the second right spiral blade to rotate in a circle. The second left spiral blade and the second right spiral blade gather the spread and cooled waste residue in a spiral, so that it can slide out of the discharge pipe and fall smoothly onto the corresponding conveyor belt device.

[0015] In a preferred embodiment, the present invention can be further configured such that the tilting rod assembly includes a tilting rod one, a tilting rod two, and a rotary drive component for driving the two to rotate. The material-turning rod includes a support shaft and a plurality of first V-shaped material-turning plates. The first V-shaped material-turning plates are spaced apart and connected to the outer circle of the support shaft. Both ends of the support shaft pass through the side wall of the rectangular cooling box and are rotatably connected. The second material-turning rod includes a second support shaft, and a second V-shaped material-turning plate is provided between adjacent first V-shaped material-turning plates. The second V-shaped material-turning plate is connected to the second support shaft. Both ends of the second support shaft pass through the side wall of the rectangular cooling box and are rotatably connected. The rotary drive component includes a fourth motor, a drive sprocket, and a driven sprocket. The drive sprocket is mounted on the outer circle of one end of the second support shaft, the fourth motor is connected to the other end of the second support shaft, and the driven sprocket is mounted on the outer circle of one end of the first support shaft. A chain connects the drive sprocket and the driven sprocket.

[0016] By adopting the above technical solution, after the fourth motor starts, it drives the second support shaft to rotate. The second support shaft synchronously drives the active sprocket to rotate. The active sprocket drives the driven sprocket to rotate through the chain drive, which in turn drives the first support shaft to rotate. At the same time, the first support shaft drives the first V-shaped turning plate to scrape the waste residue, and the second support shaft drives the second V-shaped turning plate to scrape the waste residue synchronously, exposing the lower layer of waste residue to the surface, so as to accelerate the heat dissipation and be successfully absorbed, effectively improving the cooling efficiency.

[0017] In a preferred embodiment, the present invention can be further configured such that: the air intake system includes a plurality of air intake pipes respectively passing through the front and rear side walls of the rectangular cooling box, the air intake pipes including an air intake pipe body and a cylindrical metal filter screen wrapped around one end of the air intake pipe body.

[0018] By adopting the above technical solution, the use of an air intake pipe facilitates the entry of low-temperature external gas into the inner cavity of the rectangular cooling box, achieving rapid cooling. Because a cylindrical metal filter is wrapped around one end of the air intake pipe, it prevents waste particles from clogging the pipe.

[0019] In a preferred embodiment, the present invention can be further configured such that a vibration motor is connected to the lower surface of the rectangular cooling box.

[0020] By adopting the above technical solution and setting up a vibration motor, the air-cooled inspection machine components can be driven to vibrate, which facilitates the smooth sliding of the cooled waste material.

[0021] In summary, this utility model has at least one of the following beneficial technical effects: The paving auger blades drive the waste to move and spread, thus reducing the thickness of the waste; the turning rod assembly turns the waste, exposing the lower layer of waste to the surface. Combined with the interaction of the air intake system and the heat absorption cover, the heat dissipation in the waste is accelerated in multiple dimensions. Attached Figure Description

[0033] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] Reference Figures 1-9 The present invention discloses an air-circulating, air-cooled, dry ash removal machine, comprising: two conveyor belt devices 1 and a transition shell 2 connected to the bottom of the boiler.

The width of the air-cooled slag discharge machine assembly 30 is greater than the width of the constant feed box assembly 40 and the width of the discharge pipe body 11.

[0036] The air-cooled inspection machine assembly 30 includes a rectangular cooling box 31, the top of which is open and covered with a heat-absorbing cover 32. A spreading spiral blade 33 is inserted through the upper inclined end of the rectangular cooling box 31, and a collecting spiral blade 34 is inserted through the lower inclined end of the rectangular cooling box 31.

[0037] The heat-absorbing cover 32 includes a rectangular shell 321. An exhaust pipe 322 is connected to the upper surface of the rectangular shell 321. A plurality of suction holes 323 are spaced apart on the lower surface of the rectangular shell 321. A rectangular metal filter 324 covers the lower surface of the rectangular shell 321. The rectangular shell 321 is connected to the top opening of the rectangular cooling box 31. A gas supply pipe 325 is connected to the outer end of the exhaust pipe 322. The end of the gas supply pipe 325 away from the exhaust pipe 322 is connected to the external boiler air inlet. A high-temperature resistant suction pump 326 is installed on the gas supply pipe 325. The high-temperature resistant suction pump 326 extracts gas from the rectangular shell 321, creating a negative pressure inside the rectangular shell 321. This negative pressure then draws away heat from the rectangular cooling box 31 through the suction holes 323, achieving cooling. The rectangular metal filter 324 prevents dust from the waste residue from clogging the suction holes 323, enhancing the stability of the cooling process.

[0038] The spreading spiral blade component 33 includes a second rotating shaft 331. A first left spiral blade 332 and a first right spiral blade 333 are respectively connected to the outer circumference of both ends of the second rotating shaft 331. Both ends of the second rotating shaft 331 pass through the side wall of the rectangular cooling box 31 and are rotatably connected. A second motor 334 is connected to one end of the second rotating shaft 331. The second motor 334 drives the second rotating shaft 331 to rotate, which in turn drives the first left spiral blade 332 and the first right spiral blade 333 to rotate in a circular motion. The first left spiral blade 332 and the first right spiral blade 333 spread the flat waste residue forward and backward, thereby reducing the thickness of the waste residue.

[0039] The collecting spiral blade assembly 34 includes a third rotating shaft 341. A second left spiral blade 342 and a second right spiral blade 343 are respectively connected to the outer circumference of both ends of the third rotating shaft 341. Both ends of the third rotating shaft 341 pass through the side wall of the rectangular cooling box 31 and are rotatably connected. A third motor 344 is connected to one end of the third rotating shaft 341. The third motor 344 drives the third rotating shaft 341 to rotate, which in turn drives the second left spiral blade 342 and the second right spiral blade 343 to rotate in a circular motion. The second left spiral blade 342 and the second right spiral blade 343 spirally gather the spread and cooled waste residue, facilitating its sliding out of the discharge pipe 11 and smoothly falling onto the corresponding conveyor belt device 1.

[0040] A tilting rod assembly 50 is installed inside the rectangular cooling box 31. The tilting rod assembly 50 includes a tilting rod 1 51, a tilting rod 2 52, and a rotary drive 53 for driving both to rotate. The tilting rod 1 51 includes a support shaft 1 511 and a plurality of first V-shaped tilting plates 512.

The tilting rod 2 52 includes a support shaft 2 521, and a second V-shaped tilting plate is provided between adjacent first V-shaped tilting plates 512. Plate 522, the second V-shaped turning plate 522 is connected to the second support shaft 521, both ends of the second support shaft 521 pass through the side wall of the rectangular cooling box 31 and are rotatably connected; the rotary drive component 53 includes a fourth motor 531, a drive sprocket 532 and a driven sprocket 533, the drive sprocket 532 is fitted and connected to the outer circle of one end of the second support shaft 521, the fourth motor 531 is connected to the other end of the second support shaft 521, the driven sprocket 533 is fitted and connected to the outer circle of one end of the first support shaft 511, and a chain 534 is connected between the drive sprocket 532 and the driven sprocket 533. After the fourth motor 531 starts, it drives the second support shaft 521 to rotate. The second support shaft 521 synchronously drives the drive sprocket 532 to rotate. The drive sprocket 532 drives the driven sprocket 533 to rotate through the chain 534, which in turn drives the first support shaft 511 to rotate. At the same time, the first support shaft 511 drives the first V-shaped turning plate 512 to scrape the waste residue, and the second support shaft 521 drives the second V-shaped turning plate 522 to scrape the waste residue synchronously, exposing the lower layer of waste residue to the surface, so as to accelerate heat dissipation and be successfully absorbed, effectively improving the cooling efficiency.

[0041] It also includes an air intake system 60 that supplies air to the air-cooled inspection unit 30. The air intake system 60 includes multiple air intake pipes 61 that pass through the front and rear side walls of the rectangular cooling box 31. Each air intake pipe 61 includes an air intake pipe body 611 and a cylindrical metal filter 612 wrapped around one end of the air intake pipe body 611. The use of the air intake pipe body 611 facilitates the entry of low-temperature external air into the inner cavity of the rectangular cooling box 31, achieving rapid cooling. Because the cylindrical metal filter 612 is wrapped around one end of the air intake pipe body 611, it prevents waste particles from clogging the air intake pipe body 611.

[0042] The constant feed box assembly 40 includes a feed box 41 and a feed rod 42 passing through its inner cavity. The upper inclined end of the feed box 41 is connected to the transition shell 2, and the lower inclined end is connected to the air-cooled sorting machine assembly 30. The feed rod 42 includes a first rotating shaft 421, and a plurality of scraper blades 422 are connected at intervals on the outer circle of the first rotating shaft 421. The two ends of the first rotating shaft 421 pass through the side wall of the feed box 41 and are rotatably connected. One end of the first rotating shaft 421 is connected to a first motor 423. The first motor 423 drives the first rotating shaft 421 to rotate at a constant speed in a circle. The first rotating shaft 421 drives the scraper blades 422 to rotate in a circle along its axial direction. The scraper blades 422 scrape the waste residue in the transition shell 2, so that the waste residue can enter the rectangular cooling box 31 of the air-cooled sorting machine assembly 30 evenly and smoothly, reducing the probability of blockage at the outlet of the transition shell 2.

[0043] A vibration motor 7 is connected to the lower surface of the rectangular cooling box 31. The vibration motor 7 drives the air-cooled inspection machine assembly 30 to vibrate, which facilitates the smooth sliding of the cooled waste material.

[0044] The implementation principle of this embodiment is as follows: During use, the waste slag in the boiler falls into the transition shell 2. The constant feed box assembly 40 evenly transports the waste slag in the transition shell 2 to the interior of the rectangular cooling box 31. At this time, the thickness of the transported waste slag is relatively large. Since the width of the air-cooled slag removal machine assembly 30 is greater than the width of the constant feed box assembly 40, the spreading spiral blade assembly 33 starts and spreads the waste slag spirally at both ends, reducing the thickness of the waste slag. Subsequently, the heat-absorbing cover assembly 32 works to absorb the heat contained in the waste slag. During this process, the turning rod assembly 50 operates synchronously to turn the waste slag, turning the waste slag in contact with the rectangular cooling box 31 to the upper layer, facilitating heat dissipation and smooth absorption, effectively improving heat dissipation efficiency. At the same time, the rectangular cooling box 31 maintains a negative pressure state, and the air intake system 60 can guide the external low-temperature gas into the box to further cool the waste slag. When the temperature of the waste residue drops to the target value, the collecting spiral blade 34 will gather the waste residue distributed along the width of the rectangular cooling box 31 towards the center, so that the waste residue can slide out smoothly from the discharge pipe 11 and finally fall onto the corresponding conveyor belt device 1 to complete the conveying.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
