[0042] Example

[0043] Please refer to Figures 1 to 12 The embodiment of the present application provides an online cleaning device SS for cleaning dust accumulation on a rotary gate of a microcrystalline glass furnace, comprising:

[0044] A mounting seat 10, used to be fixed to the rotating gate 200;

[0045] A power rod 20, which is installed on the operating platform 100 of the glass-ceramic furnace and is located at one end of the operating platform 100 and can be driven up and down, and the other end of the power rod 20 is movably connected to the mounting seat 10, and the power rod 20 passes through the top of the main flue 300;

[0046] A cleaning rod 30, the cleaning rod 30 is hinged to the portion of the power rod 20 located at the mounting seat 10, the cleaning rod 30 abuts against the plate surface of the rotating gate plate 200, and when the power rod 20 moves along its own length direction, the cleaning rod 30 rotates along the plate surface of the rotating gate plate 200 to scrape off the dust accumulated on the plate surface; and

[0047] The ash receiving trough 40 is used to be movably connected to the cleaning port below the main flue 300 and can receive the accumulated ash dropped by the rotary gate plate 200 after being cleaned. The ash receiving trough 40 includes an installed state and an active state. In the installed state, the ash receiving trough 40 is below the rotary gate plate 200; in the active state, the ash receiving trough 40 can be moved out of the main flue 300.

[0048] It should be noted that the operating platform 100, the main flue 300, and the rotating gate 200 are all environmental elements in the prior art, so there is no need to elaborate on their structures and functions.

[0049] A running gear (not shown) is provided at one end of the power rod 20 located at the operating platform 100 , and the running gear is used to be pulled by an external power device so that the power rod 20 moves up and down.

[0050] The device S for online cleaning of the rotary gate ash accumulation in the microcrystalline glass furnace also includes an air sealing device 50, which is used to be arranged outside the main flue 300. The air sealing device 50 can air-seal the ash receiving trough 40 in an active state to block the gas exchange between the inside and outside of the main flue 300.

[0051] There are four ash receiving grooves 40, which are arranged in the front and rear positions of the rotating gate 200. The back side of the rotating gate is not installed with a cleaning rod, because the flue gas contains a large amount of particulate matter. The flue gas facing surface of the rotating gate is easy to condense and accumulate ash due to the suction force of the induced draft fan of the de-pinning equipment, and the back side will not condense and accumulate ash under the suction force of the induced draft fan of the de-pinning equipment. In this embodiment, the width of a single ash receiving groove is 1 / 2+300mm of the width of the rotating gate. The ash received by the rotating gate at any angle can be received by the ash receiving groove. Specifically, the rotating gate 200 needs to rotate a certain angle to clean the ash, and the four ash receiving grooves 40 can adapt to the ash receiving needs under different angles. For example, in this embodiment, because the length of the cleaning rod 30 is sufficient to extend from the width direction of the rotating gate 200 (proposed below), the rotating gate 200 needs to rotate a certain angle to allow the cleaning rod 30 to move normally, otherwise it will abut against the side wall of the main flue 300. In this embodiment, the rotating gate 200 is generally selected to rotate more than 15° before operating the cleaning rod 30 to clean the ash. The ash receiving groove 40 can be used to receive the cleaned ash, and the ash receiving groove 40 can be used to receive the cleaned ash.

[0052] The ash receiving trough 40 is a drawer type, and the air sealing device 50 is arranged on the outer periphery of each ash receiving trough 40. In this way, when the ash receiving trough 40 is pulled out, the airflow ejected by the air sealing device 50 can form a curtain to block the cleaning port of the main flue 300, which can reduce the outflow of air in the main flue 300 as much as possible, avoid the reduction of the suction force in the main flue 300, and ensure that the process during kiln production is not affected. The air sealing device 50 can be further provided with a regulating valve 51, so as to open and close the air sealing device 50 according to demand. When cleaning is not required, the air sealing device 50 is closed, the ash receiving trough 40 is in the installation state, and the end of the ash receiving trough 40 is sealed with a calcium silicate plate 60 to improve the sealing performance in the main flue 300 and ensure that the airflow in the main flue 300 is not affected during operation. Of course, when the accumulated ash is swept away as a whole, it will not be scattered around due to the suction force of the main flue 300, and most of it will fall down and fall into the ash receiving trough 40.

[0053] In this embodiment, the upper plane of the ash receiving groove 40 is flush with the bottom plane of the main flue 300. This can avoid interference with the rotating gate 200 above, and at the same time, it is closer to the gate, so as to receive the scraped ash as much as possible, and reduce or avoid the ash falling to the position outside the ash receiving groove 40.

[0054] It can be understood that the active state of the ash receiving trough 40 in this embodiment refers to the state that it can be pulled out and pushed in after the calcium silicate board 60 is removed. In other embodiments, the ash receiving trough 40 can be in other styles besides the drawer type. When it can be moved, it can be regarded as an active state, and when it is fixed under the rotating gate plate 200 to receive ash, it can be regarded as an installed state. It cannot be construed as only being a drawer-type structure.

[0055] Please combine Figures 2 to 8 The mounting seat 10 of this embodiment is a lifting slot, and the power rod 20 can move up and down along the lifting slot. When the power rod 20 is at the highest position in the lifting slot, the cleaning rod 30 is vertical and the angle between it and the power rod 20 is 180°; when the power rod 20 is in the middle position in the lifting slot, the angle between the cleaning rod 30 and the power rod 20 is 90°; when the power rod 20 is at the bottom position in the lifting slot, the cleaning rod 30 is vertical and the angle between it and the power rod 20 is 0°. Among them, in this embodiment, the lifting slot is provided with a track groove 11, one end of the cleaning rod is hinged to the power rod, and the cleaning rod is fixedly connected to the limit rod 12 at the same time, and the limit rod 12 can move along the track groove. Figures 6 to 8 As shown, when the power rod moves up and down, the limit rod 12 will limit the moving track of the cleaning rod, so that the cleaning rod can rotate in accordance with the movement of the power rod at any time to complete the cleaning.

[0056] Alternatively, the lifting groove of this embodiment is set in the middle area of ​​the rotating gate plate 200, and the number of cleaning rods 30 is two, and the two cleaning rods 30 are connected to the power rod 20 and can move with the power rod 20. It can be understood that when there is only one cleaning rod 30, the lifting groove can be set near the side of the rotating gate plate 200, and the length of the cleaning rod 30 can be extended, so that when the power rod 20 drives the cleaning rod 30, the fan-shaped area swept by the cleaning rod 30 can also almost cover the rotating gate plate 200, and a good cleaning effect can also be achieved.

[0057] When the power rod 20 is in the middle position in the lifting slot, the angle between the cleaning rod 30 and the power rod 20 is 90°, and both cleaning rods 30 extend from the width direction of the rotating gate 200. In this way, the rotation range of the cleaning rod 30 is sufficient to remove the dust accumulated on the rotating gate 200.

[0058] It is understandable that when the installation position of the power rod 20 is changed, for example, when it is installed through the opening in the side wall of the main flue 300 and the power rod 20 extends laterally into the main flue 300, the external power device is configured to pull the power rod 20 to reciprocate in the horizontal direction, and adjust the movement trajectory of the cleaning rod 30 accordingly, turning it into a left and right sweep. As long as the cleaning needs can be met. No matter which direction it is installed in, it can be understood as being along the length direction of the cleaning rod 30. In particular, the power rod 20 of this embodiment is a straight rod, and the direction of movement can be understood as being along the axial direction of the power rod 20. When the power rod 20 is a special-shaped part, its direction of movement is along its length direction. Therefore, it cannot be restrictively understood that the power rod 20 of the present application can only move up and down.

[0059] In addition, the movement direction of the power rod 20 of the present embodiment is only an example. When the power rod 20 is at the bottom of the lifting groove, the cleaning rod 30 is above, or also at the bottom. The power rod 20 moves upward, and the cleaning rod 30 also sweeps across the surface of the rotating gate 200 during the movement of the power rod 20, thereby achieving a cleaning effect. In addition, the lifting groove can be circular in addition to the rectangular shape shown in the figure. This end of the power rod 20 makes a circular motion along the lifting groove, rotating back and forth like the pedal of a bicycle, and the cleaning rod 30 also follows the circular motion to scrape off the accumulated dust. These are all solutions of the present invention by those skilled in the art, which can be achieved by changing the transmission structure of the power rod 20 and the cleaning rod 30 and the structure of the lifting groove. Adapting the corresponding structure according to the different shapes of the rotating gate 200 is within the scope of our protection.

[0060] Please combine Fig.12 , the device can also be installed in the side wall of the main flue 300 in front of the rotating gate 200, and the length of the cleaning rod when it is unfolded is 1 / 2-100mm of the height of the side wall. When the rotating gate 200 is working, part of the airflow will blow on the front side wall when it hits the gate, and dust will accumulate over time. After the device is installed on the front side wall, the dust adhering to the front side wall of the rotating gate 200 can be cleaned together. The principle and function of the online cleaning device S for the rotary gate dust accumulation in the microcrystalline glass kiln are the same when installed on the rotating gate and on the front side wall. It will not be described in detail. For details, please refer to the cleaning principle of the rotary gate. The front side wall of the rotating gate is affected by the suction force of the induced draft fan of the de-pinning equipment, and the amount of dust accumulated is small and will not clump. After cleaning, the accumulated dust is drawn out of the main flue under the suction force of the induced draft fan of the de-pinning equipment, so there is no need to set up a special ash receiving trough.

[0061] The principle of this embodiment is:

[0062] There are disadvantages in the traditional cleaning method. The inventor of this application makes a specific analysis based on practical experience as follows:

[0063] 1. The operator does not enter the main flue 300 and can only clean the local dust accumulation on the rotating gate 200 through the observation window, which fails to fundamentally solve the problem:

[0064] (1) The rotary gate 200 is heavily dusted, which blocks the operation of the rotary gate 200 and causes damage to the power operation equipment of the rotary gate 200, resulting in high maintenance costs;

[0065] (2) During the cleaning process, due to the opening of the observation window, the smoke extraction force in the main flue 300 is insufficient, affecting the pressure in the kiln;

[0066] (3) The rotating gate 200 is blocked, resulting in large pressure fluctuations in the kiln during reversing, affecting the working conditions in the kiln;

[0067] (4) The rotating gate 200 is blocked and there is a lot of dust accumulation, which easily blocks the main flue 300, resulting in a small suction force in the main flue 300, and the smoke in the kiln cannot enter the heat storage chamber, resulting in many disadvantages as follows:

[0068] 1) High-temperature smoke cannot completely enter the regenerator, and the regenerator loses its function, resulting in the inability to heat the combustion air, which increases the kiln gas usage;

[0069] 2) A large amount of smoke remains in the kiln, resulting in excessive pressure in the kiln. First, the kiln brick structure is severely corroded under high pressure, affecting the safety of the kiln structure; second, the air pressure in the kiln space is high, resulting in the inability to discharge bubbles in the glass liquid;

[0070] 3) A large amount of smoke remains in the kiln and is discharged from the kiln without being treated with desulfurization and denitrification. This not only causes environmental pollution, but also endangers the occupational health of on-site operators.

[0071] 2. Clean the dust attached to the rotating gate 200 and the dust dropped from the bottom. The operator enters the main flue 300 to clean:

[0072] (1) Operators are required to enter, and all inspection doors must be opened. There is no suction force in the main flue 300, and the impact is as above (4);

[0073] (2) Working in confined spaces, the operator is more dangerous;

[0074] (3) The large amount of smoke in the kiln endangers the occupational health of operators.

[0075] From the above, it can be seen that in practice, the dust accumulation problem of the rotary gate 200 will have a lot of impact on actual production, and among traditional means, local cleaning has no substantial effect on solving the problem, and manual entry is harmful to health and affects production. The dust accumulation problem is a major pain point in this field.

[0076] This application solves the dust accumulation problem of the rotating gate 200 with a small modification through clever structural design. Considering that the temperature of the working environment of the rotating gate 200 is 300°C, the material of this device requires high strength and high temperature resistance. The power rod 20 is selected to be 50mm wide. The power equipment can be a synchronous motor that cooperates with a rack to reciprocate and drive the running gear on the power rod 20. These external power equipment and supporting transmission mechanisms have a wide range of options and will not be described here. This embodiment uses the existing power equipment of the rotating gate 200 and sets a running gear for matching drive to reduce structural changes.

[0077] On the existing operating platform 100, the power rod 20 can be driven to move up and down in the lifting and spreading groove, thereby driving the cleaning rod 30 to swing up and down to achieve the removal of dust accumulated on the rotary gate 200. After the removal is completed, you can walk from the inspection door to the air sealing device 50, open the air sealing device 50, and open the calcium silicon board 60. After the ash receiving trough 40 is pulled out, it can be directly poured at a predetermined place, and the ash receiving trough 40 can be put back. Cover the calcium silicon board 60 and close the air sealing device 50 to complete the cleaning work. If you encounter non-production time, you can also not use the air sealing device 50. You can choose according to the actual working conditions.

[0078] Compared with traditional cleaning methods, the advantages of this application are as follows:

[0079] 1. The device cleans the dust accumulated on the rotating gate plate 200 online without removing part of the brick structure of the rotating gate plate 200 and does not affect the working conditions in the kiln;

[0080] 2. The device does not require operators to enter the main flue 300 to operate, thus protecting the occupational health of operators;

[0081] 3. After the device cleans the rotating gate 200 online, the weight of the rotating gate 200 is reduced, and the failure rate of the power equipment of the rotating gate 200 is reduced;

[0082] 4. The device cleans the dust under the rotating gate plate 200 online, and the rotating gate plate 200 will not be blocked due to excessive dust accumulation, resulting in the kiln process being affected;

[0083] 5. The cleaning port of the device uses an air sealing device 50, which does not affect the airflow in the main flue 300, ensuring the normal process in the kiln;

[0084] 6. The device dredges the rotating gate 200, improves the suction force in the main flue 300, and reduces the power consumption of the out-of-stock equipment;

[0085] 7. The device clears the rotating gate at 200 positions, and the toxic smoke in the kiln enters the destocking equipment for treatment before being discharged, protecting the ecological environment from pollution;

[0086] 8. The device clears the rotating gate at 200, the pressure in the kiln is within the controlled range, and the bubbles in the glass liquid are discharged naturally;

[0087] The device clears the rotating gate at 200, and the high-temperature smoke in the kiln completely enters the heat storage chamber, thereby improving the function of the heat storage chamber and reducing gas energy consumption.

[0088] The following is the application practice process and corresponding performance:

[0089] 1. If the kiln pressure changes greatly during the reversing period, and the rotary gate 200 power equipment and process parameter factors are excluded, check whether the rotary gate 200 and the dust accumulation at the rotary gate 200 are blocking the operation of the rotary gate 200;

[0090] 2. It is determined that the rotary gate 200 is blocked from running due to a lot of dust accumulation on the rotary gate 200 and there, resulting in uncontrolled adjustment of the rotary gate 200;

[0091] 3. Open the air sealing device 50, take out the sealing calcium silicon board 60, pull out the ash receiving groove 40, clean up the ash accumulated in the ash receiving groove 40, put it back into the ash receiving groove 40, install the sealing calcium silicon board 60 on the outside, and close the air sealing device 50 at that location;

[0092] 4. Clean the four ash receiving slots 40 in the same manner as in step 3;

[0093] 5. Ask the control room personnel about the reversing time. After the reversing is completed and the kiln process is normal, the assistant personnel will check the operation of the online cleaning device S of the rotary gate dust accumulation of the microcrystalline glass kiln from the observation window. The operator will control the online cleaning device S of the rotary gate dust accumulation of the microcrystalline glass kiln until the cleaning is completed;

[0094] 6. Clean the dust on the rotating gate 200 and the dust on the inner wall of the main flue 300 in the same way as step 5;

[0095] 7. During the cleaning process, stop the operation 3 minutes before switching and place the cleaning rod 30 at a vertical angle to the ground;

[0096] 8. After the dust accumulation on the rotary gate 200 and the dust accumulation on the inner wall of the main flue 300 are cleaned, repeat step 3 to collect the dust accumulation in the ash trough 40;

[0097] 9. On-site recovery.

[0098] The situation is as follows:

[0099] Serial number project Example Comparative Example 1 Technology No impact The impact is great, and the recovery period is 3 days 2 Rotating gate failure rate 0 12 times / year 3 Ecological Environment No impact Toxic smoke leaks out, harming the ecological environment 4 Occupational Health No impact Toxic fumes endanger the occupational health of operators

[0102] In summary, the online cleaning device S for cleaning the rotary gate ash accumulation in the microcrystalline glass kiln of the present application drives the cleaning rod 30 to move on the rotary gate 200 through the power rod 20, which can effectively remove the ash accumulation, and through the movable ash receiving groove 40, the ash accumulation can be moved out of the main flue 300 without affecting the production. Compared with traditional means, the modification is relatively small and the effect is significant, which not only ensures the production but also avoids the damage to the health of personnel.
