Description

Technical Field

[0001] The invention relates to the technical field of spraying vehicles, in particular to a rotary spraying vehicle. Background Art

[0002] The filter bag inside the simple harmonic dust collector for crystal pulling furnace usually refers to the filter bag used in the dust removal equipment in the crystal pulling furnace (such as single crystal silicon growth furnace). The main function of this filter bag is to filter and capture the dust and particles generated during the crystal pulling process to keep the working environment clean and the equipment running normally.

[0003] The filter bag of the simple harmonic dust collector used in the crystal pulling furnace will retain thick dust inside after long-term use, which greatly increases the resistance of the filter bag and seriously affects the crystal pulling process.

[0004] At present, the traditional method for cleaning the residual dust in the filter bag of the harmonic dust collector used in the crystal pulling furnace relies on manual handheld high-pressure gas equipment, which goes deep into the interior from the cleaning port and sprays directly upwards to remove the dust. This operation method is not only time-consuming and labor-intensive, but also inefficient. In addition, because the operator needs to be in close contact with the dust environment, long-term exposure poses a serious threat to physical health and increases the risk of occupational diseases.

[0037] Example 1

[0038] Reference Figure 1-6 , rotary spraying vehicle, including:

[0039] The vehicle body 1 is made of solid metal material and has sufficient carrying capacity and stability. A frame handle 2 is fixedly provided on one side of the vehicle body 1 to facilitate operation by the operator. The vehicle body 1 serves as a mobile platform for the entire equipment, and a plurality of wheels 3 are fixedly installed at the bottom thereof to facilitate movement at the work site. The wheels 3 are universal wheels to ensure that the vehicle body 1 can be flexibly moved in various complex environments. A blocking plate 5 is fixedly provided on the top of the vehicle body 1. The blocking plate 5 is used to seal the ash bin opening during the spraying operation to prevent dust leakage.

[0040] The rotating mechanism is arranged on the vehicle body 1, and mainly includes a motor bracket 29, a vertical tube outer tube 26, a ventilation shaft 21, a deep groove ball bearing 25, an oil seal 24, a hole elastic ring 27, a driving motor 30 and a coupling 28. The motor bracket 29 is fixedly installed on the top of the vehicle body 1 and is the main component for supporting the rotating mechanism. A vertical outer tube 26 is fixedly installed on the motor bracket 29 by bolts, which serves as the core supporting structure of the rotating mechanism and the blowing mechanism. Inside the vertical outer tube 26, a hole elastic ring 27, a deep groove ball bearing 25, and an oil seal 24 are installed in sequence from bottom to top. The hole elastic ring 27 is limited by the oil seal 24 and the deep groove ball Bearing 25 and oil seal 24 are used to seal gas to prevent leakage, thereby ensuring smooth rotation and sealing of the ventilation shaft 21. The ventilation shaft 21 is fixed in the vertical tube outer tube 26 through a deep groove ball bearing 25. A ventilation head 20 is fixed on the top by bolts, and an O-ring 22 is embedded to strengthen the sealing. A one-way thrust ball bearing 23 is installed on the bottom outer ring of the ventilation head 20. The lower rotating surface of the one-way thrust ball bearing 23 is fixedly connected to the top of the vertical tube outer tube 26 to withstand the axial force of the entire rotating mechanism and ensure the stable rotation of the ventilation shaft 21. The driving motor 30 is connected to the ventilation shaft 21 through a coupling 28 to realize the driving function.

[0041] The blowing mechanism is arranged on the rotating mechanism, including an inner air delivery pipe 38, a graphite copper sleeve 37, an outer rotating pipe 35 and an ejector pipe 36. The inner air delivery pipe 38 passes through the ventilation head 20 and is fixedly connected to the ventilation shaft 21. A graphite copper sleeve 37 is fixedly arranged on the outside to enhance the sealing and guiding properties. Six evenly distributed openings are provided on the outside of the inner air delivery pipe 38 and the graphite copper sleeve 37. The outer rotating pipe 35 is sealed and rotated on the outside of the graphite copper sleeve 37. The outer rotating pipe 35 is connected to the inner air delivery pipe 38 and the graphite copper sleeve through six staggered ejector pipes 36 that are fixedly connected. The six openings on 37 are connected to realize the injection of high-pressure gas. One end of the outer rotating tube 35 is fixedly installed with a rotating tube end flange 41, and a deep groove ball bearing 40 is embedded in the inner side of the rotating tube end flange 41. The inner ring of the rotating tube end flange 41 is fixedly installed with an end shaft 39, and the end shaft 39 is sealed and inserted in the inner gas transmission pipe 38. One side of the rotating tube end flange 41 is installed with an elastic retaining ring 43 for the shaft, which is used to axially limit the outer rotating tube 35, and the rotating tube end cover 42 is installed by bolts to seal the gas, and stable rotation and limitation are achieved through the deep groove ball bearing 40 and the elastic retaining ring 43 for the shaft.

[0042] A six-way dial 32 is fixed to one end of the outer rotating tube 35 close to the ventilation head 20. The outer diameter of the six-way dial 32 is circularly rotated to install six outer rotating bearings 33, and the inner diameter is circularly rotated to install six inner rotating bearings 34, to ensure the stability of the blowing mechanism during horizontal rotation and axial rotation. A stop shaft 31 is fixed to one side of the vertical tube outer tube 26, which is used to cooperate with the outer rotating bearings 33 during rotation to realize the axial rotation of the outer rotating tube 35. The plane on the vertical tube outer tube 26 is designed as a guide rail and a groove, which is used to guide and limit the rotation path of the outer rotating tube 35.

[0043] On the basis of the first embodiment, the second embodiment further includes:

[0044] A swing frame base 8 is provided on the top of the vehicle body 1, which is connected to an X-axis swing frame 13 through a pin shaft 10. The top of the X-axis swing frame 13 is connected to a Y-axis swing frame 9. An endoscope 11 is fixed on the top of the Y-axis swing frame 9. The endoscope 11 is electrically connected to an endoscope screen 4 placed on the frame handle 2 through a data line for displaying images inside the ash bin.

[0045] The X-axis swing frame 13 and the Y-axis swing frame 9 are respectively connected to the X-axis handle 19 and the Y-axis handle 14 through the pull wire 15 to achieve position adjustment. The frame handle 2 is provided with a stepper motor programmer 16, a stepper motor controller 17 and a power module 18. The power module 18 provides power to the stepper motor programmer 16, the stepper motor controller 17 and the endoscope screen 4. The stepper motor programmer 16 sets the rotation program of the drive motor 30, and the stepper motor controller 17 receives the instruction and drives the drive motor 30 to work, thereby realizing precise control of the rotating mechanism.

[0046] A wheel bracket 7 is also provided at the bottom of the vehicle body 1, and a support wheel 6 is rotatably provided at the bottom of the wheel bracket 7 to provide stable support when inserted into the ash bin opening.

[0047] However, as is well known to those skilled in the art, the working principles and wiring methods of the endoscope screen 1, endoscope 11, stepper motor programmer 16, stepper motor controller 17, power module 18 and drive motor 30 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0048] The working principle and use process of this technical solution are as follows: first, the operator pushes the rotary spraying vehicle to the vicinity of the ash bin opening of the simple harmonic dust collector to ensure that the vehicle body 1 is stably parked, then checks whether the power module 18 is powered on, provides power to the stepper motor programmer 16, the stepper motor controller 17 and the endoscope screen 4, and then sets the rotation program of the drive motor 30 through the stepper motor programmer 16 to ensure that the spraying mechanism can rotate and spray according to the predetermined trajectory;

[0049] Then the operator holds the frame handle 2, moves the vehicle body 1 through the wheel 3, and inserts the rotating mechanism and the blowing mechanism into the ash bin cleaning port. During the insertion process, the supporting wheel 6 is supported on the inner wall of the steel pipe at the ash bin port to keep the blowing mechanism horizontal. When the rotating mechanism and the blowing mechanism are in place, the blocking plate 5 automatically or manually blocks the ash bin port to prevent dust leakage when cleaning the filter bag. At this time, the endoscope 11 penetrates into the ash bin, and the operator observes the dust condition of the filter bag in the ash bin through the endoscope screen 4. Then, according to the needs, the Y-axis pull handle 14 and the X-axis pull handle 19 are operated to control the Y-axis swing frame 9 and the X-axis swing frame 13 to swing along the Y-axis and X-axis directions respectively, and the position of the endoscope 11 is adjusted to observe the bottom of the filter bag in all directions and determine the cleaning position;

[0050] When the cleaning position is determined, first connect the vertical tube outer tube 26 to the external air compressor, and then the stepper motor controller 17 starts the drive motor 30 according to the instruction of the programmer 16. The drive motor 30 drives the ventilation shaft 21 to rotate through the coupling 28. At this time, the high-pressure gas enters the inner air pipe 38 through the ventilation shaft 21, and the drive motor 30 drives the inner air pipe 38 and the outer rotating tube 35 outside it to rotate synchronously through the ventilation shaft 21. At this time, the outer rotating tube 35 rotates without spin on the vertical tube outer tube 26 through the inner rotating bearing 34 on the six-point dial 32. When the outer rotating tube 35 rotates to the spin starting position, the outer rotating bearing 33 first contacts the blocking shaft 31, thereby forcing the outer rotating tube 35 to rotate 1 / 12 of a circle. Then the inner rotating bearing 34 continues to contact with the outer tube 26 of the vertical tube, forcing the outer rotating tube 35 to continue to rotate 1 / 12 of a circle, so that the outer rotating tube 35 can rotate 1 / 6 of a circle outside the inner gas transmission tube 38. While the outer rotating tube 35 rotates, the high-pressure gas is guided to the outer rotating tube 35 through the graphite copper sleeve 37, and then ejected through the ejector tube 36. During the rotation of the six ejector tubes 36 on the outer rotating tube 35, only the ejector tube 36 currently in the vertical upward direction will eject the high-pressure gas, and at the same time, it will draw the surrounding air to eject together, so as to spray and clean the filter bag. The rotating tube 35 rotates horizontally. When the ejector tube 36 rotates to the position of the stop shaft 31, the outer rotating bearing 33 on the six-point dial 32 is blocked, forcing the outer rotating tube 35 to rotate 60° along the axial direction and switch to the next ejector tube 36 for blowing. During the blowing cleaning process, the operator continuously observes the cleaning status of the filter bags in the ash bin through the endoscope screen 4. According to the observation results, the rotation speed and blowing intensity of the blowing mechanism are adjusted in time to ensure that the filter bags are thoroughly cleaned. When all the filter bags are cleaned, the drive motor 30 is turned off to stop the rotation and blowing of the blowing mechanism.

[0051] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
