Description

Technical Field

[0001] This utility model relates to the technical field of Maeltz kiln cleaning equipment, and in particular to a tool for cleaning the fire-drawing hole channel of a Maeltz kiln. Background Technology

[0002] The working principle of the Maeltz kiln is to achieve parallel calcination in the calcining kiln and preheating of limestone in the non-calcining kiln by fully absorbing the heat from the exhaust gas through a connecting channel between the two kiln chambers. The calcining kiln and the non-calcining kiln chamber automatically switch periodically to optimize lime quality and maximize energy savings. During the switching operation of the Maeltz kiln, changes in airflow speed and direction cause particles and dust carried by the airflow to deposit in the intermediate and annular channels. Under high-temperature conditions, dust is prone to agglomerate in the intermediate and annular channels. The slow deposition of agglomerates eventually obstructs the normal flow of air within the kiln, causing airflow turbulence and affecting the normal operation of the Maeltz kiln.

[0003] To address the aforementioned issues, when the channels become severely clogged, treatment through the firing holes is impossible. Current technology involves shutting down the kiln for cleaning, typically for 15 days. During this time, workers can enter the kiln to conduct a comprehensive inspection and cleaning of the channels. Accumulated ash is removed using shovels and other tools; lumps may require crushing with pneumatic picks or similar equipment before removal. The cleaned material is then transported out of the kiln through openings in the kiln body.

[0004] The above-mentioned kiln shutdown and cleaning methods will greatly extend production time and increase production costs. Moreover, the cleaning operation time is generally more than 6 hours. The long-term exposure of workers to high-temperature environments will greatly affect their health and the labor intensity is high. Utility Model Content

[0005] This invention addresses the technical problems of existing kiln shutdown cleaning methods, which increase production costs, affect the health of operators, and increase the labor intensity of operators, by providing a tool for cleaning the blast hole channel of a Maeltz kiln.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A tool for cleaning the blast hole channel of a Maeltz kiln includes a cleaning rod and a cleaning plate. One end of the cleaning plate is fixedly connected to one end of the cleaning rod along its length, and the width of the cleaning plate is greater than the lateral dimension of the cleaning rod. The cleaning plate is used to extend into the blast hole of the Maeltz kiln.

[0008] The beneficial effects of this utility model are as follows: When ash accumulates in the annular and direct channels of the Maeltz kiln, during maintenance work, workers outside the Maeltz kiln can hold the other end of a cleaning rod and insert it into the annular or direct channel through the ignition hole. The cleaning plate can then be used to assist in sweeping and cleaning the ash in the annular and direct channels, thereby reducing the time that workers need to enter the Maeltz kiln. This improves upon existing kiln shutdown cleaning methods, which increase production costs, affect the health of workers, and increase the labor intensity of workers. Furthermore, the cleaning plate can create a larger cleaning area, improve the cleaning effect, and shorten the cleaning time of the ignition hole channel.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the cleaning rod has an air hole extending through its length, and the other end of the cleaning rod is connected to an air pipe. One end of the air pipe is connected to one end of the air hole, and the other end is used to connect to compressed gas.

[0011] The beneficial effects of adopting the above-mentioned further solution are: during the cleaning process, high-pressure gas can be blown into the air hole through the air pipe, and the accumulated dust in the annular channel or direct channel can be cleaned by the gas, thereby improving the cleaning efficiency and reducing the deposition.

[0012] Furthermore, one end of the air tube is fixedly connected to a nut, and the other end of the cleaning rod is threadedly connected to the nut.

[0013] The advantages of adopting the above-mentioned further solution are: the cleaning rod and the air tube can be quickly connected by using a nut and rotating, and after use, they can be easily disassembled and stored separately.

[0014] Furthermore, the other end of the air hole extends to both sides of one end of the cleaning rod corresponding to the thickness direction of the cleaning plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, during the cleaning process, the gas blown out from the air hole can be blown to both sides of the cleaning plate at the same time, and the accumulated dust on both sides of the cleaning plate can be blown away, thereby improving the cleaning effect.

[0016] Furthermore, one end of the cleaning rod along its length is provided with an installation groove, one end of the cleaning plate along its length is adapted to and inserted into the installation groove, and the cleaning plate is fixedly connected to the groove wall of the installation groove.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the cleaning plate is clamped and limited by the two groove walls of the installation groove, preventing the cleaning plate from detaching from the cleaning rod during the cleaning process.

[0018] Furthermore, the air pipe is equipped with a valve.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the amount of gas introduced into the air hole can be controlled by the valve, thereby controlling the gas pressure that blows away the deposited ash and thus reasonably controlling the ash cleaning effect.

[0020] Furthermore, the cleaning rod includes an extension rod and a sleeve rod, one end of the extension rod is fixedly connected to one end of the cleaning plate along its length, and the other end is threadedly connected to one end of the sleeve rod.

[0021] The beneficial effects of adopting the above-mentioned further solution are: when the cleaning rod is inserted into the ignition hole and the ash cleaning operation is performed, the length of the entire cleaning rod can be extended or shortened by rotating the extension rod or the sleeve rod so that the extension rod and the sleeve rod rotate relative to each other, so as to ensure that the cleaning plate contacts and cleans the ash, while avoiding the cleaning plate sinking too deep into the ash and making it difficult to disturb the ash.

[0022] Furthermore, the cleaning rod includes an extension rod, a sleeve rod, and a positioning bolt. One end of the extension rod is fixedly connected to one end of the cleaning plate along its length, and the other end is slidably connected to one end of the sleeve rod. The other end of the extension rod has a through threaded hole. One end of the sleeve rod has multiple insertion holes spaced apart along its length. The positioning bolt is inserted into one of the insertion holes and threadedly connected to the threaded hole.

[0023] The beneficial effects of adopting the above-mentioned further solution are: when inserting the cleaning rod into the ignition hole and performing the ash cleaning operation, the length of the entire cleaning rod can be extended or shortened by first removing the positioning bolt and causing the extension rod and sleeve rod to move relative to each other. Then, the positioning bolt is inserted into the connected insertion hole and threaded hole at the same time to ensure that the cleaning plate contacts and cleans the accumulated ash, while avoiding the cleaning plate sinking too deep into the accumulated ash and making it difficult to disturb the accumulated ash.

[0024] Furthermore, at least one end of the cleaning plate in the width direction is provided with a rotating groove, the rotating groove is rotatably connected to a rotating shaft, and a limiting shaft is inserted therein, one end of the limiting shaft passes through the cleaning plate and extends along the length direction of the cleaning plate, and at least one end of the cleaning plate in the width direction is also provided with an extension plate, one end of the extension plate is fixed with an ear plate rotatably connected to the rotating shaft, and the limiting shaft is inserted into the ear plate.

[0025] The beneficial effects of adopting the above-mentioned further solution are as follows: when the cleaning plate is inserted into the firing hole, the extension plate rotates and adheres to the cleaning plate. When the cleaning plate passes through the firing hole, the extension plate rotates relative to the cleaning plate until the limit shaft can simultaneously insert the cleaning plate and the ear plate, so that the extension plate extends the width of the cleaning plate, increases the cleaning area of ​​the cleaning plate, and improves the cleaning effect.

[0026] Furthermore, a positioning plate is fixedly connected to one end of the cleaning plate where the rotating groove is formed. One end of the positioning plate is fixedly connected to one side of the cleaning plate in the thickness direction, and the other end abuts against the corresponding side of the extension plate.

[0027] The beneficial effect of adopting the above-mentioned further solution is that when the extension plate rotates relative to the cleaning plate, the positioning plate limits the rotation of the extension plate, so as to ensure that the limiting shaft can be smoothly inserted into the cleaning plate and the ear plate at the same time.

[0040] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0041] like Figure 3 In the prior art, the Maeltz kiln 1 is equipped with an annular channel 11 and a direct channel 12. Above the annular channel 11 and the direct channel 12, there are fire-pulling holes 13 to check the material level, check the airflow, detect the temperature, and clean the annular channel 11 and the direct channel 12 to prevent blockage and ensure normal airflow circulation and effective heat transfer in the kiln.

[0042] During the switching operation of the Maerz kiln 1, the changes in the speed and direction of the airflow cause particles and dust carried in the airflow to deposit in the direct connection channel 12 and the annular channel 11. Under high temperature conditions, the dust is prone to form agglomerates in the direct connection channel 12 and the annular channel 11. The slow deposition of agglomerates eventually hinders the normal flow of airflow in the kiln, causing airflow turbulence in the kiln and affecting the normal operation of the Maerz kiln.

[0043] To address the aforementioned issues, existing technologies involve shutting down the kiln for cleaning. This method significantly extends production time and increases production costs. Furthermore, the cleaning process typically takes more than 6 hours, resulting in prolonged exposure of workers to high temperatures, which greatly impacts their health and leads to high labor intensity.

[0044] To address the aforementioned issues, this utility model provides a tool for cleaning the blast hole channels of a Maerz kiln. This tool allows for auxiliary cleaning of the annular channel 11 and direct channel 12 inside the Maerz kiln 1 from outside during routine maintenance operations, eliminating the need for dedicated kiln shutdown cleaning. This reduces the time personnel spend exposed to high-temperature environments and minimizes the extended production time and increased production costs caused by kiln shutdown cleaning.

[0045] The following is a detailed description of a tool for cleaning the fire-drawing hole channel of a Maeltz kiln provided by this utility model.

[0046] Example 1

[0047] like Figures 1 to 3 A tool for cleaning the fire-removing hole channel of a Maeltz kiln includes a cleaning rod 2 and a cleaning plate 3. One end of the cleaning plate 3 is fixedly connected to one end of the cleaning rod 2 along its length, and the width of the cleaning plate 3 is greater than the lateral dimension of the cleaning rod 2. The cleaning plate 3 is used to extend into the fire-removing hole 13 of the Maeltz kiln 1.

[0048] The beneficial effects of this embodiment are as follows: When ash accumulates in the annular channel 11 and the direct channel 12 of the Maeltz kiln 1, during maintenance work, the workers outside the Maeltz kiln 1 can hold the other end of the cleaning rod 2 and insert it into the annular channel 11 or the direct channel 12 through the ignition hole 13. The cleaning plate 3 is then used to assist in sweeping and cleaning the ash accumulated in the annular channel 11 and the direct channel 12, thereby reducing the time that workers need to enter the Maeltz kiln 1. This improves upon the existing kiln shutdown cleaning method, which increases production costs, affects the health of workers, and increases the labor intensity of workers. Furthermore, the cleaning method formed by the cleaning plate 3 can create a larger cleaning area, improve the cleaning effect, and shorten the cleaning time of the ignition hole channel.

[0049] The cleaning plate 3 can be made of 10×10cm steel plate with a thickness of 4mm.

[0050] Example 2

[0051] like Figure 1 and Figure 2 Based on embodiment 1, the cleaning rod 2 has an air hole 21 extending through its length, and the other end of the cleaning rod 2 is connected to an air pipe 4. One end of the air pipe 4 is connected to one end of the air hole 21, and the other end is used to connect to compressed gas.

[0052] The beneficial effect of adopting the preferred solution in the above embodiments is that, during the cleaning process, high-pressure gas can be blown into the air hole 21 through the air pipe 4, and the accumulated dust in the annular channel 11 or the direct channel 12 can be cleaned by the gas, thereby improving the cleaning efficiency and reducing the deposition.

[0053] At the same time, using compressed air can cool the cleaning channel tools, extend the time for the tools to clean accumulated dust, and prevent the cleaning plate 3 from deforming due to high temperature.

[0054] The compressed air flow rapidly exchanges heat with the high-temperature ash clumps in the annular channel 11 or the direct channel 12, making the clumps easy to loosen and cleaning local floating ash, thus improving the degree of ash removal.

[0055] The cleaning plate 3 at the front end of the cleaning channel tool is made of steel plate, and the cleaning process will not cause damage to the refractory material.

[0056] The time for cleaning the passage was reduced from 6 hours to 2 hours, shortening the time workers were exposed to high temperatures (the average temperature of the platform at the blast hole 13 is 30-40℃, which is significantly lower than the temperature inside the Maeltz kiln 1, thus improving safety) and reducing the labor intensity of workers.

[0057] The cleaning rod 2 can be made of 2.5-3m DN25 seamless 304 steel pipe, which is resistant to high temperature and has good strength.

[0058] DN32 rubber hose can be used for air tube 4; compressed air with a pressure of 0.4-0.6 MPa can be used for compressed gas.

[0059] It should be noted that, as existing technology, a gas channel 14 is provided on the Maerz kiln 1 (e.g., Figure 3 When the cleaning process is carried out by compressed gas, the gas can be discharged from the gas channel 14.

[0060] Example 3

[0061] like Figure 1 and Figure 2 Based on embodiments 1 and 2, one end of the air tube 4 is fixedly connected to a nut 41, and the other end of the cleaning rod 2 is threadedly connected to the nut 41.

[0062] The advantage of the preferred solution in the above embodiments is that the cleaning rod 2 and the air pipe 4 can be quickly connected by rotating the nut 41, and can be easily disassembled and stored separately after use.

[0063] Specifically, one side of the nut 41 is fixedly connected to one end of the air pipe 4, and the other end of the cleaning rod 2 is provided with an external thread to achieve a threaded connection with the nut 41.

[0064] Example 4

[0065] like Figure 1 and Figure 2 Based on embodiments 1-3, the other end of the air hole 21 extends to both sides of the cleaning rod 2 corresponding to the thickness direction of the cleaning plate 3.

[0066] The beneficial effect of adopting the preferred solution in the above embodiments is that, during the cleaning process, the gas blown out from the air hole 21 can be blown to both sides of the cleaning plate 3 at the same time, and the accumulated dust on both sides of the cleaning plate 3 can be blown away, thereby improving the cleaning effect.

[0067] Example 5

[0068] like Figure 1 and Figure 2 Based on embodiments 1-4, a mounting groove 22 is provided at one end of the cleaning rod 2 along its length, and one end of the cleaning plate 3 along its length is adapted to and inserted into the mounting groove 22, and the cleaning plate 3 is fixedly connected to the groove wall of the mounting groove 22.

[0069] The advantage of the preferred solution in the above embodiments is that the cleaning plate 3 is clamped and limited by the two groove walls of the mounting groove 22, preventing the cleaning plate 3 from detaching from the cleaning rod 2 during the cleaning process.

[0070] The depth of the mounting groove 22 can be 2cm.

[0071] Example 6

[0072] like Figure 4 Based on Examples 1-5, the air pipe 4 is equipped with a valve 42.

[0073] The advantage of adopting the preferred solution in the above embodiments is that the amount of gas entering the air hole 21 can be controlled by the valve 42, thereby controlling the gas pressure that blows the deposited ash and thus reasonably controlling the ash cleaning effect.

[0074] As a parallel embodiment of the above, valve 42 may also be provided with cleaning rod 2 near the other end of air pipe 4.

[0075] Example 7

[0076] like Figure 5 Based on embodiments 1-6, the cleaning rod 2 includes an extension rod 23 and a sleeve rod 24. One end of the extension rod 23 is fixedly connected to one end of the cleaning plate 3 along its length, and the other end is threadedly connected to one end of the sleeve rod 24.

[0077] The beneficial effect of the preferred solution in the above embodiments is that when the cleaning rod 2 is inserted into the ignition hole 13 and the ash is cleaned, the length of the entire cleaning rod 2 can be extended or shortened by rotating the extension rod 23 or the sleeve rod 24 so that the extension rod 23 and the sleeve rod 24 rotate relative to each other, so as to ensure that the cleaning plate 3 contacts and cleans the ash, while avoiding the cleaning plate 3 from sinking too deep into the ash and making it difficult to disturb the ash.

[0078] As one of the parallel solutions in the above embodiments, an external thread is provided at the other end of the extension rod 23, and an internal thread hole is provided at one end of the sleeve rod 24, so as to realize the threaded connection between the extension rod 23 and the sleeve rod 24.

[0079] As one of the parallel solutions in the above embodiments, an internal threaded hole is provided at the other end of the extension rod 23, and an external thread is provided at one end of the sleeve rod 24, so as to realize the threaded connection between the extension rod 23 and the sleeve rod 24.

[0080] Among them, the air hole 21 passes through the extension rod 23 and the sleeve rod 24 along the length direction.

[0081] Example 8

[0082] like Figure 6Based on embodiments 1-7, the cleaning rod 2 includes an extension rod 23, a sleeve rod 24, and a positioning bolt 25. One end of the extension rod 23 is fixedly connected to one end of the cleaning plate 3 along its length, and the other end is slidably connected to one end of the sleeve rod 24. The other end of the extension rod 23 is provided with a threaded hole 231. One end of the sleeve rod 24 is provided with a plurality of insertion holes 241 spaced apart along its length. The positioning bolt 25 is inserted into one of the insertion holes 241 and threadedly connected to the threaded hole 231.

[0083] The beneficial effect of the preferred solution in the above embodiments is that when the cleaning rod 2 is inserted into the ignition hole 13 and the ash is cleaned, the length of the entire cleaning rod 2 can be extended or shortened by first removing the positioning bolt 25 and causing the extension rod 23 and the sleeve rod 24 to move relative to each other. Then, the positioning bolt 25 is inserted into the connected insertion hole 241 and threaded hole 231 at the same time to ensure that the cleaning plate 3 contacts and cleans the ash, while avoiding the cleaning plate 3 sinking too deep into the ash and making it difficult to disturb the ash.

[0084] Based on the above embodiment, a polygonal hole is provided at one end of the sleeve rod 24, and the cross-section of one end of the extension rod 23 is polygonal, so as to fit and insert into the polygonal hole. After insertion, the extension rod 23 and the sleeve rod 24 will not be relative to each other, so as to ensure that the threaded hole 231 and one of the insertion holes 241 are connected as the sleeve rod 24 and the extension rod 23 slide relative to each other.

[0085] Among them, the air hole 21 passes through the extension rod 23 and the sleeve rod 24 along the length direction.

[0086] Example 9

[0087] like Figure 7 Based on embodiments 1-8, at least one end of the cleaning plate 3 in the width direction is provided with a rotating groove 31, the rotating groove 31 is rotatably connected to a rotating shaft 32, and a limiting shaft 33 is inserted therein. One end of the limiting shaft 33 passes through the cleaning plate 3 and extends along the length direction of the cleaning plate 3. At least one end of the cleaning plate 3 in the width direction is also provided with an extension plate 34, one end of the extension plate 34 is fixed with an ear plate 35 rotatably connected to the rotating shaft 32, and the limiting shaft 33 is inserted into the ear plate 35.

[0088] The beneficial effect of the preferred solution in the above embodiments is that when the cleaning plate 3 is inserted into the ignition hole 13, the extension plate 34 rotates and adheres to the cleaning plate 3. When the cleaning plate 3 passes through the ignition hole 13, the extension plate 34 rotates relative to the cleaning plate 3, so that the limiting shaft 33 can be inserted into the cleaning plate 3 and the ear plate 35 at the same time, so that the extension plate 34 extends the width of the cleaning plate 3, increases the cleaning area of ​​the cleaning plate 3, and improves the cleaning effect.

[0089] When the cleaning operation is completed and the cleaning plate 3 is pulled out of the ignition hole 13, the extension plate 34 rotates in the opposite direction and attaches to the cleaning plate 3 to ensure that the cleaning plate 3 can be smoothly pulled out of the ignition hole 13.

[0090] Example 10

[0091] like Figure 7 Based on embodiments 1-9, a positioning plate 36 is fixedly connected to one end of the cleaning plate 3 with a rotating groove 31. One end of the positioning plate 36 is fixedly connected to one side of the cleaning plate 3 in the thickness direction, and the other end abuts against the corresponding side of the extension plate 34.

[0092] The beneficial effect of the preferred solution in the above embodiments is that when the extension plate 34 rotates relative to the cleaning plate 3, the positioning plate 36 limits the rotation of the extension plate 34, so as to ensure that the limiting shaft 33 can be smoothly inserted into the cleaning plate 3 and the ear plate 35 at the same time.

[0093] As a parallel solution of the above embodiment, a torsion spring (not shown in the figure) is sleeved on the rotating shaft 32. The two ends of the torsion spring are fixedly connected to the ear plate 35 and the cleaning plate 3, respectively, so that the extension plate 34 can rotate relative to the cleaning plate 3 through the torsion spring, so that the limiting shaft 33 can be inserted into the cleaning plate 3 and the ear plate 35 at the same time.
