Description

Technical Field

[0001] This invention belongs to the field of ultrasonic nozzles, and particularly relates to a high-temperature pyrolysis ultrasonic nozzle. Background Technology

[0002] Compared with traditional two-fluid spraying, ultrasonic spraying has advantages such as high coating uniformity, high raw material utilization, high precision in coating thickness control, thinner coating thickness, less spatter, no nozzle clogging, and low maintenance costs. Compared with coating processes such as vacuum evaporation and CVD, ultrasonic spraying is a more economical thin film coating process, especially for the preparation of large-area thin films, where the equipment cost of ultrasonic spraying is significantly lower than that of vacuum coating equipment.

[0003] Ultrasonic spraying requires the use of ultrasonic transducers to convert electrical energy into mechanical energy, generating heat during the process. This heat needs to be cooled. Currently, a small amount of compressed air or gas is injected into the tail of the ultrasonic nozzle. The cooling gas is then delivered to the transducer via a pipe, circulates internally, and carries away the heat before being discharged from the tail of the outer casing. However, the transducers used in current ultrasonic spraying can only generate vibration amplitude in one direction, and this amplitude is co-located with the nozzle axis, resulting in poor atomization of the sprayed liquid within the pipe.

[0004] Vortex nozzles utilize an air shield to create a wide-patterned "vortex" dispersion, making them ideal for coating flat objects such as PEMs (fuel cells) and solar cells. Compared to other types of nozzles, vortex nozzles provide more uniform coating on curved surfaces.

[0005] Combining ultrasonic spraying with vortex nozzles will result in better atomization of the sprayed liquid. However, currently, the vortex nozzle is placed after the sprayed liquid being acted upon by the ultrasonic transducer, and the ultrasonic transducer and the vortex nozzle are two independent atomizing elements. If the two are coupled in a design, the atomization effect can be further improved.

[0006] In addition, for working environments with temperatures around 600 degrees Celsius, the nozzle housing and internal sealing rings need to be made of high-temperature resistant materials. However, their service life is short at high temperatures, so cooling measures are required to extend their service life.

[0007] This invention designs a high-temperature pyrolysis ultrasonic nozzle to solve the above problems. Summary of the Invention

[0008] To address the aforementioned deficiencies in the prior art, this invention discloses a high-temperature pyrolysis ultrasonic nozzle, which is implemented using the following technical solution.

[0009] A high-temperature pyrolysis ultrasonic nozzle includes a shell, a top cover A, an air inlet pipe A, an air outlet pipe A, a liquid inlet pipe A, a power interface, a liquid inlet pipe B, a spherical shell, an ultrasonic transducer, a vibrating ball, a spray pipe, a sealing ring, a column sleeve A, a trigger rod, a piston disc, a column sleeve B, a piston sleeve, and an air inlet pipe B. The top cover A is bolted to the upper end of the cylindrical shell. The top cover A has an air inlet pipe A and an air outlet pipe. The liquid inlet pipe A is installed in the middle of the top cover A. The liquid inlet pipe B, which seals the lower end of the shell, is installed inside the shell. The upper end of the liquid inlet pipe B is inserted into the liquid inlet pipe A. The spherical shell at the lower end of the thicker portion of the liquid inlet pipe B is installed in a receiving groove at the upper end of the column sleeve A. An ultrasonic transducer, electrically connected to the power interface on the top cover A, is nested on the upper end of the liquid inlet pipe B. The liquid inlet pipe B, the liquid inlet pipe A, the shell, and the column sleeve A have a structure to facilitate the axial vibration of the liquid inlet pipe B. A vibrating ball is fitted inside the spherical shell with a clearance fit. A conical sealing ring is connected between the vibrating ball and the inner wall of the expansion groove at the lower end of the inlet pipe B, which introduces the liquid in the inlet pipe B into the liquid passage hole on the vibrating ball; the inner wall of the sleeve A has a structure to buffer the lateral vibration of the spray pipe that connects the lower end of the vibrating ball to the liquid passage hole; the lower end of the sleeve A is threaded with a sleeve B with a tapered lower end, and the annular groove B at the lower end of the sleeve A is sealed to the annular groove C at the upper end of the sleeve B; an air inlet pipe B connected to the annular groove B is installed on the outer shell; the inner wall of the sleeve B is densely covered with vortex grooves connected to the annular groove C; a stepped annular groove with a larger upper end and a smaller lower end and an open lower end is formed between the annular groove A at the lower end of the sleeve A and the inner wall of the sleeve B; a piston sleeve that pushes down the cold air that enters the sleeve B from the vortex groove is axially sealed and slides in the lower part of the stepped annular groove, and a piston disc that slides axially sealed in the upper part of the stepped annular groove, with hydraulic oil filling the space between the piston disc and the piston sleeve; the piston disc is engaged with a trigger rod installed on the ball shell.

[0010] As a further improvement to this technology, the air inlet pipe A of the upper cover A has an extension pipe that leads cold air to the ultrasonic transducer inside the outer shell; the ultrasonic transducer is electrically connected to the power interface via a wire.

[0011] As a further improvement to this technology, the fine part of the inlet pipe B is fitted with the inlet pipe A by an elastic sealing gasket A.

[0012] As a further improvement to this technology, the annular disc A on the thick part of the inlet pipe B is fitted with the fixed ring in the inner wall of the outer shell by an elastic sealing gasket B; a lower cover is installed at the lower end of the outer shell by bolts, and the lower cover is fitted with the annular disc A by an elastic sealing gasket B.

[0013] As a further improvement to this technology, the inner wall of the spherical shell has a rigid liner that fits with the gap of the vibrating ball.

[0014] As a further improvement to this technology, an elastic sealing gasket B is fitted between the outer ring disk B of the spherical shell and the bottom of the receiving groove; an upper cover B is installed on the upper end of the column sleeve A by bolts, and the upper cover B and the ring disk B are fitted by an elastic sealing gasket B.

[0015] As a further improvement to this technology, the lower end of the piston sleeve has an annular plate that can instantly push down the vortex of cold air that enters the sleeve B from the annular groove C through the vortex groove.

[0016] As a further improvement to this technology, a ring sleeve is nested and screwed onto the small-diameter cylindrical surface of the annular groove A, which is in a sealing and sliding fit with the piston sleeve, and a buffer pad is fitted between the ring sleeve and the piston disc; the outer side of the ring sleeve has a groove that facilitates its rotation by a lever.

[0017] As a further improvement to this technology, the cushioning pad is made of rubber.

[0018] As a further improvement to this technology, four circumferentially evenly distributed leaf springs are fitted between the spray pipe and the inner wall of the column sleeve A; one end of the leaf spring is connected to the inner wall of the column sleeve A.

[0019] The trigger rod slides within the groove at the bottom of the receiving slot.

[0020] Compared to traditional ultrasonic vortex nozzles, this invention utilizes the vibration of an ultrasonic transducer to drive a vibrating ball within the inner lining of the spherical shell to vibrate in all directions, rather than just in a single vertical direction. This allows the liquid sprayed outward from the spray pipe connected to the vibrating ball to be more fully atomized under the omnidirectional vibration of the spray pipe. Simultaneously, the cold air entering the annular groove C from the air inlet pipe forms a cold air vortex at the end of the spray pipe through circumferentially distributed vortex grooves. This further atomizes the liquid sprayed from the spray pipe and atomized by the ultrasonic transducer vibration, resulting in a more uniform coating.

[0021] In addition, the air intake pipe A in this invention introduces cold air through the extension pipe into the area surrounding the ultrasonic transducer inside the housing, effectively cooling the ultrasonic transducer and the housing. At the same time, the cold air entering the annular groove B, annular groove C and column sleeve B through the air intake pipe B effectively cools the column sleeve A and column sleeve B. The cooling of the housing allows the sealing gasket A and sealing gasket B inside the housing to function normally at a high temperature of 600 degrees Celsius. The effective cooling of the column sleeve A and column sleeve B allows the buffer gasket and sealing gasket B inside the column sleeve A and column sleeve B to function normally at a high temperature of 600 degrees Celsius, respectively, to function normally in buffering and sealing roles.

[0022] In this invention, the hydraulic oil in the stepped annular groove formed between the lower annular groove A of the column sleeve A and the inner wall of the column sleeve B drives the piston sleeve to move rapidly downward when the piston disc moves downward. This causes the vortex cold air entering the column sleeve B from the vortex groove to be sprayed out axially, and further atomizes the liquid sprayed out by the spray pipe.

[0023] This invention has a simple structure and good performance. Attached Figure Description

The annular groove B33 at the lower end of sleeve A28 and the annular groove C43 at the upper end of sleeve B42 form a sealing connection. Figure 1 , 4 As shown, an intake pipe B49 communicating with the annular groove B33 is installed on the outer casing 1; as Figure 4 , 5 As shown in Figure 7, the inner wall of the sleeve B42 is densely covered with vortex grooves 44 that communicate with the annular groove C43; the annular groove A31 at the lower end of the sleeve A28 forms a stepped annular groove with a larger upper end and a smaller lower end and an open lower end between it and the inner wall of the sleeve B42; the lower part of the stepped annular groove is axially sealed and slides with a piston sleeve 47 that pushes down the cold air that enters the sleeve B42 from the vortex groove 44; the upper part of the stepped annular groove is axially sealed and slides with a piston disc 39; the space between the piston disc 39 and the piston sleeve 47 is filled with hydraulic oil; the piston disc 39 cooperates with the trigger rod 38 installed on the ball housing 17.

[0034] like Figure 2 , 3 As shown, the upper cover A3 has an extension tube 10 at the air inlet pipe A4 to guide cold air into the outer casing 1 for an ultrasonic transducer 21; the ultrasonic transducer 21 is electrically connected to the power interface 8 via a wire 22.

[0035] like Figure 3 As shown, the fine part 13 of the liquid inlet pipe B12 and the liquid inlet pipe A7 are fitted together by an elastic sealing gasket A11.

[0036] like Figure 3 As shown, the annular disc A15 on the thick part 14 of the inlet pipe B12 and the fixed ring 2 in the inner wall of the outer shell 1 are fitted together by an elastic sealing gasket B20; a lower cover 19 is installed at the lower end of the outer shell 1 by bolts 6, and the lower cover 19 and the annular disc A15 are fitted together by an elastic sealing gasket B20.

[0037] like Figure 4 As shown, the inner wall of the spherical shell 17 has a rigid inner liner 23 that fits with the vibrating ball 24 with a clearance.

[0038] like Figure 4 , 6 As shown, an elastic sealing gasket B20 is fitted between the outer ring plate B18 of the spherical shell 17 and the bottom of the receiving groove 29; a top cover B37 is installed on the upper end of the column sleeve A28 by bolts 6, and the top cover B37 and the ring plate B18 are fitted with an elastic sealing gasket B20.

[0039] like Figure 4 As shown, the lower end of the piston sleeve 47 has an annular plate 48 that can instantly push down the vortex of cold air that enters the sleeve B42 from the annular groove C43 through the vortex groove 44.

[0040] like Figure 4 As shown, a ring sleeve 40 is nested and screwed onto the small-diameter cylindrical surface of the annular groove A31, which is in a sealing and sliding fit with the piston sleeve 47. A buffer pad 9 is fitted between the ring sleeve 40 and the piston disc 39. The outer side of the ring sleeve 40 has a groove 41 that facilitates its rotation by a lever.

[0041] like Figure 4 As shown, the buffer pad 9 is made of rubber.

[0042] like Figure 4 , 7 As shown, four circumferentially evenly distributed leaf springs 36 are fitted between the spray pipe 26 and the inner wall of the sleeve A28; one end of the leaf spring 36 is connected to the inner wall of the sleeve A28.

[0043] like Figure 4 , 7 As shown, the trigger rod 38 slides within the groove 35 at the bottom of the receiving groove 29.

[0044] The working process of this invention is as follows: In the initial state, all trigger rods 38 are in contact with the piston disc 39.

[0045] When this invention is used to spray a flat or curved surface, cold air is first introduced into the ultrasonic transducer 21 inside the housing 1 through the air inlet pipe A4 and the extension pipe 10. The cold air entering the housing 1 is discharged through the air outlet pipe 5, thereby keeping the inside of the housing 1 at a low temperature and cooling the ultrasonic transducer 21. At the same time, cold air is introduced into the annular groove C43 on the sleeve B42 through the air inlet pipe B49. The cold air entering the slide groove 35C enters the sleeve B42 through the vortex groove 44, forming a vortex-like cold air that is discharged through the conical opening and cools the sleeve A28 and the sleeve B42.

[0046] Then, the ultrasonic transducer 21 is activated, which drives the inlet pipe B12 to undergo axial high-frequency vibration. The axially high-frequency vibration of the inlet pipe B12 drives the vibrating ball 24 to undergo small-amplitude high-frequency vibration in all directions through the spherical shell 17 and the rigid inner liner 23 of the inner wall of the spherical shell 17. The vibrating ball 24 drives the spray pipe 26 to undergo small-amplitude high-frequency vibration in all directions. At the same time, the inlet pipe B12 drives the piston disc 39 to move downward through the gap of the trigger rod 38. The piston disc 39 drives the piston sleeve 47 to move downward significantly through the gap of the hydraulic oil. The downwardly moving piston sleeve 47 pushes the vortex cold air that enters the column sleeve A28 from the vortex groove 44 outward through the conical opening via the ring plate 48.

[0047] Next, the coating is uniformly sprayed onto the curved or flat surface through the inlet pipe A7, inlet pipe B12, vibrating ball 24, and spray pipe 26. The coating entering the spray pipe 26 is atomized to the maximum extent due to the omnidirectional small-amplitude high-frequency vibration of the vibrating ball 24 and the spray pipe 26. The vortex cold air entering the column sleeve B42 from the annular groove C43 through the vortex groove 44 is discharged through the lower cone of the column sleeve B42 under the downward pushing action of the annular plate 48, which further atomizes the atomized coating in the spray pipe 26. Thus, the coating sprayed from the spray pipe 26 is atomized to the maximum extent, thereby enabling the present invention to achieve uniform spraying on both flat and curved surfaces.

[0048] In summary, the beneficial effects of this invention are as follows: This invention uses the vibration of the ultrasonic transducer 21 to drive the vibrating ball 24 in the inner lining 23 of the spherical shell 17 to vibrate in all directions, rather than only in a single vertical direction. This allows the liquid sprayed outward from the spray pipe 26 connected to the vibrating ball 24 to be more fully atomized under the all-around vibration of the spray pipe 26. Simultaneously, the cold air entering the annular groove C43 through the air inlet pipe B49 forms a cold air vortex at the end of the spray pipe 26 via the circumferentially distributed vortex grooves 44. This further atomizes the liquid sprayed from the spray pipe 26 and atomized by the ultrasonic transducer 21, resulting in a more uniform coating.

[0049] In addition, the air inlet pipe A4 of this invention introduces cold air through the extension pipe 10 into the area surrounding the ultrasonic transducer 21 inside the outer casing 1, effectively cooling the ultrasonic transducer 21 and the outer casing 1. At the same time, the cold air entering the annular groove B33, annular groove C43 and column sleeve B42 through the air inlet pipe B49 effectively cools the column sleeve A28 and column sleeve B42. The cooling of the outer casing 1 allows the sealing gasket A11 and sealing gasket B20 inside the outer casing 1 to perform their sealing function normally at a high temperature of 600 degrees Celsius. The effective cooling of the column sleeve A28 and column sleeve B42 allows the buffer gasket 9 and sealing gasket B20 inside the column sleeve A28 and column sleeve B42 to perform their buffering and sealing functions normally at a high temperature of 600 degrees Celsius, respectively.

[0050] In this invention, the hydraulic oil in the stepped annular groove formed between the lower annular groove A31 of the sleeve A28 and the inner wall of the sleeve B42 drives the piston sleeve 47 to move rapidly downward when the piston disc 39 moves downward. This causes the vortex cold air entering the sleeve B42 from the vortex groove 44 to be sprayed out axially, and further atomizes the liquid sprayed out by the spray pipe 26.
