Description

Technical Field

[0001] This utility model relates to the field of rotary kiln lining treatment, and more specifically, to a structure for a controllable discharge port for rotary kiln lining. Background Technology

[0002] Rotary kiln lining refers to a protective layer of clinker formed by material adhering to the surface of the kiln lining bricks. Rotary kiln lining may peel off due to reasons such as the temperature exceeding the solidification temperature or uneven heating.

[0003] Currently, there is no separate discharge outlet for the detached kiln lining in rotary kilns. The detached lining is discharged from the kiln tail along with the material. This discharge of the lining can cause damage to the kiln tail due to the impact. Furthermore, the kiln tail is typically a "trumpet-shaped" or "conical" structure, with its diameter slightly narrowing to ensure even material flow. This makes the large volume of lining prone to clogging the kiln tail. In existing technology, the lining is pulled out from the tail section by workers using hooks. However, this method makes it difficult to separate the lining from the calcined material, further affecting the rotary kiln's output. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a controllable discharge outlet structure for rotary kiln lining. By opening a lining outlet on the side wall of the rotary kiln tail cylinder, workers can easily discharge the lining from the outlet to the sorting mechanism using hooks, and large volumes of lining can be collected in a storage box without affecting the discharge of roasted material from the rotary kiln tail cylinder, thus reducing safety risks.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A controllable discharge outlet structure for rotary kiln slag includes a rotary kiln tail cylinder, a slag outlet is provided on the side wall of the rotary kiln tail cylinder, a protective door is installed at the slag outlet, and the slag outlet is connected to a sorting mechanism. The sorting mechanism includes a discharge device and a slag collection device. The discharge device includes a first channel, a second channel is connected to the end of the first channel, a third channel is connected to the lower middle part of the first channel, a fourth channel is connected to the lower part of the third channel, and a fifth channel is connected to the side of the third channel near the second channel. Among them, multiple grid bars are installed at the bottom of the first channel, which is located at the inlet of the third channel; The second channel has a first baffle inserted at the end away from the first channel; The fifth channel is connected to a second baffle at one end near the third channel; The kiln scum collection device includes a shell with a first opening on one side and a retrieval port on another side perpendicular to the first opening. A second opening is located at the bottom of the shell. A cover plate is hinged to the outer side of the shell outside the retrieval port. A storage box is detachably connected to the middle of the shell. Multiple holes are provided at the lower end of the storage box. Through the kiln scum outlet on the side wall of the rotary kiln tail section, workers can easily discharge the kiln scum from the outlet to the sorting mechanism using hooks. The storage box also facilitates the collection of large volumes of kiln scum, avoiding manual entry into the high-temperature area and reducing safety risks.

[0007] Furthermore, the grid bars are parallel to the direction of kiln skin movement, which makes it less likely for the kiln skin to be blocked by the grid bars when it moves in the first channel, and the calcined material can separate from the kiln skin and fall through the gaps between the grid bars.

[0008] Furthermore, the first opening is connected to the end of the second channel away from the first channel, and the second opening is connected to the end of the fifth channel away from the third channel, so that the remaining calcined material and kiln skin in the second channel can enter the shell, and the calcined material in the shell can enter the fifth channel through the second opening.

[0009] Furthermore, the cover plate can cover the retrieval port, and the first baffle can block the end of the second channel away from the first channel, and the second baffle can block the end of the fifth channel close to the third channel, so that the cover plate can limit the storage box by covering the retrieval port, and the first baffle and the second baffle can temporarily isolate the kiln skin collection device from the discharge device.

[0010] Furthermore, a support block is fixedly connected to the outer end of the cover plate, a pin is rotatably connected to the middle of the support block, a wedge block is fixedly connected to the end of the housing away from the second channel, and a handle is provided on the side of the storage box, so that the cover plate can tightly cover the retrieval port through the pin and the wedge block.

[0011] Furthermore, the end of the pin away from the support block is wedge-shaped, and the end of the pin away from the support block matches the wedge-shaped block, so that the pin can tightly cover the retrieval opening through the wedge-shaped block and the cover plate.

[0012] Compared with existing technologies, the advantages of this utility model are: (1) This solution allows workers to easily discharge the kiln skin from the kiln skin outlet to the sorting mechanism by using hooks, and to collect large volumes of kiln skin in the storage box, without affecting the discharge of the roasted material from the rotary kiln tail cylinder, thus reducing safety risks.

[0013] (2) During the process of removing the storage box, the first baffle and the second baffle can temporarily isolate the kiln skin collection device from the rotary kiln, avoiding the workers being placed in a high-temperature environment. Attached Figure Description

[0019] Please see Figure 1-6 A controllable discharge outlet structure for rotary kiln slag includes a rotary kiln tail cylinder 3, a kiln slag outlet 4 on the side wall of the rotary kiln tail cylinder 3, a protective door 5 installed on the kiln slag outlet 4, and a sorting mechanism connected to the kiln slag outlet 4. The sorting mechanism includes a discharge device 1 and a kiln slag collection device 2. The discharge device 1 includes a first channel 101, a second channel 102 connected to the end of the first channel 101, a third channel 103 connected to the lower middle part of the first channel 101, a fourth channel 104 connected to the lower part of the third channel 103, and a fifth channel 105 connected to the side of the third channel 103 near the second channel 102. Among them, multiple grid bars 106 are installed at the bottom of the first channel 101 at the feed inlet of the third channel 103; Among them, the end of the second channel 102 that is away from the first channel 101 is connected to the first baffle 107; Among them, the fifth channel 105 is connected to a second baffle 108 at one end near the third channel 103; The kiln scum collection device 2 includes a housing 201, a first opening 202 on the side of the housing 201, a material retrieval port 203 on one side of the housing 201 perpendicular to the first opening 202, a second opening 204 at the bottom of the housing 201, a cover plate 205 hinged to the outside of the housing 201 outside the material retrieval port 203, and a storage box 209 detachably connected to the middle of the housing 201. The lower end of the storage box 209 has multiple holes 210.

[0020] Please see Figure 2-5 The grid bars 106 are parallel to the direction of kiln skin movement, making it less likely for the kiln skin to be blocked by the grid bars 106 when moving in the first channel 101, and allowing the calcined material to separate from the kiln skin and fall through the gaps between the grid bars 106. The first opening 202 is connected to the end of the second channel 102 away from the first channel 101, and the second opening 204 is connected to the end of the fifth channel 105 away from the third channel 103, allowing the remaining calcined material and kiln skin in the second channel 102 to enter the shell 201, and allowing the calcined material in the shell 201 to enter the fifth channel 105 through the second opening 204.

[0021] Please see Figure 2-6 The cover plate 205 can cover the retrieval port 203, and the first baffle 107 can block the end of the second channel 102 away from the first channel 101, and the second baffle 108 can block the end of the fifth channel 105 near the third channel 103. This allows the cover plate 205 to limit the storage box 209 by covering the retrieval port 203. The first baffle 107 and the second baffle 108 can temporarily isolate the kiln skin collection device 2 from the discharge device 1. A support block 206 is fixedly connected to the outer end of the cover plate 205. A pin 207 is rotatably connected to the middle of the support block 206. A wedge block 208 is fixedly connected to the end of the shell 201 away from the second channel 102. A handle 211 is provided on the side of the storage box 209, so that the cover plate 205 can tightly cover the retrieval port 203 through the pin 207 and the wedge block 208. The end of the pin 207 away from the support block 206 is wedge-shaped, and the end of the pin 207 away from the support block 206 matches the wedge block 208, so that the pin 207 can tightly cover the retrieval port 203 through the wedge block 208 and the cover plate 205.

[0022] When a large volume of kiln lining falls off and blocks the rotary kiln tail section 3, the staff opens the protective door 5 at the kiln lining outlet 4 and hooks the kiln lining blocking the rotary kiln tail section 3 out to the kiln lining outlet 4. The large volume of kiln lining and some of the calcined material enter the first channel 101 together under the action of the hook. Then the kiln lining passes through the first channel 101 and through the grid bar 106 into the second channel 102. Most of the calcined material falls into the third channel 103 through the gaps between the grid bars 106, and a small part of the calcined material passes through the grid bars 106 and enters the second channel 102 together with the kiln lining. The kiln lining and some of the calcined material pass through the second channel 102 into the storage box 209. The kiln lining is stored in the middle of the storage box 209. At the same time, the calcined material passes through the hole 210 and enters the third channel 103 through the fifth channel 105. Finally, the calcined material is discharged through the fourth channel 104 and collected. The large volume of kiln lining is stored in the storage box 209. When the storage box 209 contains too much kiln slag, the first baffle 107 is inserted into the second channel 102, sealing the end of the second channel 102 away from the first channel 101. Then, the second baffle 108 is inserted into the fifth channel 105, sealing the end of the fifth channel near the third channel 103. Since the collecting device 2 is located inside the plant, the first baffle 107 and the second baffle 108 isolate the high-temperature calcined material from the plant space, preventing the plant temperature from rising too much. Rotate the pin 207 so that it no longer contacts the wedge block 208. Rotate the cover plate 205 along the hinge position to no longer cover the extraction port 203203. Then, use the handle 21... 1. Remove the storage box 209 from the shell 201, remove the kiln sludge stored in the storage box 209, and put the storage box 209 back into the shell 201. Rotate the cover plate 205 along the hinge position to cover the extraction port 203203, and use the rotating pin 207 to engage the pin 207 and the wedge block 208 together. Slide the first baffle 107 away from the side of the second channel 102, and the first baffle 107 does not come off from the side of the second channel 102. Then slide the second baffle 108 away from the side of the fifth channel 105, and the second baffle 108 does not come off from the side of the fifth channel 105. The collection of kiln sludge is completed. By opening a kiln skin outlet 4 on the side wall of the rotary kiln tail cylinder 3, workers can easily discharge the kiln skin from the kiln skin outlet 4 to the sorting mechanism using hooks, and the storage box 209 can collect large volumes of kiln skin without affecting the discharge of the roasted material from the rotary kiln tail cylinder 3, thus reducing safety risks.

[0023] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
