DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] See also Figures 1 to 5The utility model provides a technical solution: a device for uniformly applying anti-coking paint for the combustion chamber of a garbage incinerator, comprising a load-bearing frame 1, one end of the interior of the load-bearing frame 1 is rotatably connected to a first screw 2, one end of the top of the load-bearing frame 1 is slidably connected to a push frame 3, the other end of the top of the load-bearing frame 1 is fixedly connected to a fixed base 5, the bottom of the push frame 3 is sleeved and threadedly connected to the outer wall of the first screw 2, an outer push rod 4 is welded to the top of the push frame 3, a turntable 6 is rotatably connected to one side of the fixed base 5 corresponding to the push frame 3, the turntable 6 is slidably connected to a clamping member 8 through a first hydraulic cylinder 7 mounted on its surface, a hydraulic column 9 is fixedly connected to the surface of the load-bearing frame 1, and the power output end of the hydraulic column 9 is bolted to the bottom of the bracket 10. The bracket 10 is located between the fixed base 5 and the push frame 3. The load-bearing frame 1 is fixedly connected to the second hydraulic cylinder 12 through a vertical frame 11 opened on one side of its outer wall. The power output end of the second hydraulic cylinder 12 is bolted to the top of the beam 13. The internal rotation of the beam 13 is connected to the reverse screw 14. The bottom of the beam 13 is slidingly connected to the symmetrically distributed limiting side plates 15. The internal rotation of the outer push rod 4 is connected to the second screw 16. The outer wall of the second screw 16 is installed with an inner push rod 17. One end of the inner push rod 17 is sleeved and threadedly connected to the outer wall of the second screw 16. The other end of the inner push rod 17 extends to the outside of the outer push rod 4 and is fixedly connected to the spray assembly 18. The spray assembly 18 is located below the limiting side plate 15.

[0024] The spray assembly 18 includes a liquid storage tank 1801, a connecting support rod 1802 and an extension rod 1803. The connecting support rod 1802 is distributed in a ring shape on the outer wall of one end of the liquid storage tank 1801, and the extension rods 1803 are all slidably connected to the inside of the connecting support rod 1802. Limiting blocks 1804 are provided on both sides of the outer wall of the extension rod 1803 located at the innermost end of the connecting support rod 1802.

[0025] In this embodiment, Figure 1 As shown, the push rack 3 forms a horizontal transmission structure on one side of the turntable 6 through the first screw 2, and the specifications of the bottom of the push rack 3 are smaller than the gap specifications formed by the distribution between the hydraulic columns 9; first, the push rack 3 serves as the bearing component of the spray assembly 18, and the transmission structure of the first screw 2 can be used to realize the propulsion of the spray assembly 18. Compared with the difficult-to-control movement smoothness when manually holding the spray gun, this horizontal transmission structure can ensure that the spray assembly 18 always moves along a predetermined straight line trajectory to avoid offset, thereby greatly improving the uniformity of the coating, and the distance between the hydraulic columns 9 and the limitation of the specifications of the bottom of the push rack 3 effectively avoid obstruction of the movement of the push rack 3, thereby ensuring the smooth progress of the entire spraying process.

[0026] In this embodiment, Figure 2As shown, the interior of the fixed base 5 is rotatably connected to a driving gear 501 and a driven gear 502, and the driving gear 501 and the driven gear 502 are meshed and connected, and the driven gear 502 is integrally connected to one end of the turntable 6 through a shaft running through its axis, and the axis point of the turntable 6 and the axis point of the liquid storage tank 1801 are located at the same horizontal position; although the high-pressure nozzle 1805 is distributed in an annular shape and can provide multi-angle spraying to a certain extent, due to factors such as the slight difference in spraying distance and angle and the diffusion of paint in the air, there may still be some local areas where the spraying is not uniform, and compared with the current static treatment In the process, the workpiece fixed on the turntable 6 can rotate with the turntable 6 by utilizing the transmission structure of the gear group inside the fixed base 5, so that the workpiece can continuously change its angle and position surrounded by the annular high-pressure nozzle 1805, ensuring that each part can receive the paint spray from different directions, further improving the all-round coverage effect, and ensuring the uniformity of the coating. The position distribution of the axis point of the turntable 6 and the axis point of the liquid storage tank 1801 can ensure that when the spray component 18 moving toward this side extends to the inside of the workpiece, its high-pressure nozzle 1805 can be distributed along the axis point, so that the inside of the workpiece can be sprayed at a more uniform angle, increasing the uniformity of paint adhesion.

[0027] In this embodiment, Figure 1 and Figure 2 As shown, the clamping members 8 are arc-shaped and slide on the surface of the turntable 6 in an equiangularly distributed structural form, and the concave inner wall of the clamping members 8 is coated with a rubber layer, and the side of the clamping members 8 that is in contact with the turntable 6 forms a right-angled edge, and at the same time, the clamping members 8 form an opening and closing structure through the first hydraulic cylinder 7; the combustion chamber workpiece for processing can be fixed by the equiangularly distributed clamping members 8, and the opening and closing range of the clamping members 8 can be changed by the driving stroke of the first hydraulic cylinder 7 to adapt to workpieces of different specifications, and the equiangular distribution of the clamping members 8 makes the workpiece uniformly stressed in all directions when being clamped, and one side forms a right-angled edge, forming a favorable supporting structure, which not only increases the contact area between the clamping members 8 and the workpiece, further improves the stability of the clamping, but also prevents the workpiece from sliding or tilting in the vertical direction, and the rubber coating on the inner wall increases the friction between the clamping members 8 and the workpiece, which can effectively prevent the workpiece from sliding or loosening during rotation, thereby ensuring the accuracy and stability of spraying.

[0028] In this embodiment, Figure 1 and Figure 3As shown, the bracket 10 is arc-shaped and is located between the clamping member 8 and the limiting side plate 15, and the top of the limiting side plate 15 extends to the inside of the crossbeam 13, and is sleeved and threadedly connected to the two ends of the outer wall of the reverse screw 14, and the limiting side plates 15 are relatively movable through the reverse screw 14, and the inner walls of the limiting side plates 15 are connected to rollers through rubber pads; when the workpiece is first placed on the surface of the bracket 10, the hydraulic column 9 drives the bracket 10 to rise, so that the workpiece can be easily pushed into the turntable 6 and fixed with the clamping member 8. The arc-shaped bracket 10 can guide the workpiece to fall accurately in the appropriate position, which is convenient for operation. The operator performs subsequent operations. Taking into account the uncertainty of the combustion chamber specifications, for workpieces that are too large, a single clamping part 8 may lack stability. The limiting side plates 15 adjust the spacing through the reverse screw 14. When the workpiece rotates, the symmetrically distributed limiting side plates 15 and the rollers on the inner wall provide a supporting sliding track for the rotation of the workpiece. The rubber layer has a certain elastic structure and can also reduce shaking. It provides auxiliary support for the clamping part 8 at the other end, ensuring that the workpiece always rotates on a relatively stable track, greatly reducing the problem of inconsistent coating thickness due to shaking of the workpiece.

[0029] In this embodiment, Figure 4 As shown, the inner push rod 17 slides and retracts inside the outer push rod 4 through the second screw 16, and the spray assembly 18 forms a horizontal transmission structure through the inner push rod 17; the inner push rod 17 can slide and retract inside the outer push rod 4, which means that the spray assembly 18 can be pushed to a farther position. For workpieces of different sizes, especially larger-sized waste incinerator combustion chambers, by extending the length of the inner push rod 17, the spray assembly 18 can be pushed deeper into the workpiece to ensure full coverage, effectively avoiding the tediousness of frequent replacement of operating components due to workpieces of different sizes, and greatly improving the versatility of the equipment.

[0030] In this embodiment, Figure 4 and Figure 5As shown, a cavity is provided inside the extension rod 1803, and a spring is installed in the cavity, and one end of the limit block 1804 is fixedly connected to the spring and movably connected to the two ends of the outer wall of the extension rod 1803 through the spring, and at the same time, a number of through holes for plugging the connection limit blocks 1804 are provided on the outer wall of the connecting support rod 1802 at equal distances, and a metal pipe is fixed to the outer wall of the connecting support rod 1802 through a pipe mounting frame, and one end of the metal pipe is threadedly connected to a high-pressure nozzle 1805, and the other end of the metal pipe is connected to the liquid storage tank 1801 through a bellows; the sliding and telescopic structure of the extension rod 1803 and the connecting support rod 1802 can extend the contact distance between the high-pressure nozzle 1805 and the inner wall of the workpiece, which makes the spraying assembly 18 Whether dealing with a combustion chamber with a larger inner diameter or a combustion chamber with a smaller inner diameter, the length of the extension rod 1803 can be adjusted to ensure that the high-pressure nozzle 1805 is in a suitable spraying position. This not only avoids the problem of uneven spraying range due to an inner diameter that is too large or too small, but also greatly avoids the unnecessary frequent replacement of spray parts due to specification limitations, greatly improves work efficiency, and reduces operation time. The high-pressure nozzle 1805 is connected through a metal pipe with a rigid structure, which effectively ensures the position stability of the high-pressure nozzle 1805 during the spraying process. At the same time, the other end of the metal pipe is connected to the liquid storage tank 1801 through a bellows, so that when the extension rod 1803 is adjusted in length, the pipe can stretch accordingly to ensure smooth delivery of the paint.

[0031] The use method and advantages of the utility model: The device for uniformly applying anti-coking coating to the combustion chamber of a garbage incinerator has the following working process when in use:

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, it should be noted that a cavity is provided in the liquid storage tank 1801, and a small high-pressure plunger pump is provided in the cavity. One end of the small high-pressure plunger pump is connected to the liquid storage tank 1801 through a pipeline, and the other end of the small high-pressure plunger pump is connected to a number of pipe openings provided outside the liquid storage tank 1801 through a pipeline, and the high-pressure nozzle 1805 is connected to the pipe opening through a bellows. The combustion chamber workpiece to be processed is mounted on the surface of the bracket 10, with its open end facing the side of the spraying component 18. After the mounting is completed, the power is started, and the hydraulic column 9 pushes the bracket 10 to lift. The operator pushes the workpiece toward one end of the turntable 6. During the pushing process, the power output end of the first hydraulic cylinder 7 of the power supply is started to push the clamping part 8 toward the axis of the turntable 6. According to the work The gear of the part is used to cover and fix the workpiece with the clamping part 8. The bottom of the workpiece can be fitted on one end of the edge of the clamping part 8 to complete the fixation of the clamping part 8. The auxiliary support structure is selected according to the actual size of the workpiece. When the workpiece is too small, the bracket 10 can be directly used as an auxiliary support. When the workpiece is too large, the power is started, the second hydraulic cylinder 12 drives the crossbeam 13 to descend, and the external servo motor of the crossbeam 13 drives the reverse screw 14 to rotate, so that the two limiting side plates 15 move synchronously and in opposite directions, close to the outer wall of the open end of the workpiece, and its inner wall roller will squeeze the rubber layer due to the shape of the outer wall of the workpiece, adjust the position to fit the outer wall of the workpiece, complete the fixation of the auxiliary support, and adjust the high-pressure nozzle 1805 according to the inner diameter of the workpiece at this time. Position. If the inner diameter of the workpiece is too large, the limit block 1804 in the through hole on the outer wall of the connecting support rod 1802 will be squeezed inward, and the limit block 1804 will shrink under the elastic structure. The extension rod 1803 that has lost the limit structure can slide. According to the specific positioning of the high-pressure nozzle 1805, the extension rod 1803 will be engaged in the corresponding through hole on the outer wall of the connecting support rod 1802 using the limit block 1804. After adjusting the fixed position of each group of high-pressure nozzles 1805, the first screw 2 is used to make the push frame 3 push the spray assembly 18 to move toward the inside of the workpiece under the horizontal transmission structure. If the workpiece specification is too large, the second screw 16 can be started to make the inner push rod 17 slide and extend from the inside of the outer push rod 4 under the horizontal transmission structure until the bottom of the spray assembly 18 is attached to the bottom of the workpiece. After confirming the fixation of the spraying assembly 18, turn on the power supply and valve, and the high-pressure plunger pump inside the liquid storage tank 1801 delivers the medium for spraying to the high-pressure nozzle 1805 through the pipeline. During the spraying process of the high-pressure nozzle 1805, the active gear 501 is driven by the servo motor to rotate the driven gear 502 meshing with it, thereby driving the turntable 6 to rotate, and finally realizing the rotation of the workpiece fixed by the clamping part 8 on the surface of the turntable 6, while the other end of the workpiece slides in the support track formed between the limiting side plates 15, and at the same time the second lead screw 16 rotates, the inner push rod 17 converts the rotational motion into linear motion and drives the spraying assembly 18 being sprayed to move from the inside to the outside with a smooth transmission structure, and when the inner push rod 17 travels to the maximum form range,The push frame 3 drives the spray assembly 18 to move out from the inner wall of the workpiece through the transmission structure of the first screw 2.
