[0002] With the rapid development of the lithium battery industry, the production process of lithium battery positive and negative electrodes has become one of the most important links, namely the spray drying process. However, the shape of the dry particles sprayed by the existing spray equipment is easily damaged and the size is uneven. Utility Model Content

[0003] In view of the above problems, the present application provides an atomizing device and a spraying equipment, which are beneficial to improving the consistency of the atomized particle size and ensuring the integrity of the particle morphology.

[0004] On the one hand, an embodiment of the present application provides an atomization device, including: an atomization disk, having an inner wall surface and an outer wall surface relatively arranged along its own radial direction, a plurality of guide channels being arranged on the atomization disk, the plurality of guide channels being distributed at intervals around the center of the atomization disk, one end of the guide channel penetrating the inner wall surface to form an inlet and the other end penetrating the outer wall surface to form an outlet; a adapter portion, arranged on the atomization disk and enclosed with the atomization disk to form a feed chamber, the feed chamber being connected to each guide channel; wherein, along the axial direction of the atomization disk, the orthographic projection of the guide channel extends along an arc trajectory.

[0005] In the above scheme, by setting the axial projection of the guide channel to a structure extending along an arc trajectory, the slurry in the feed chamber enters the guide channel and is atomized to form atomized particles, and the atomized particles are buffered to temporarily stay in the guide channel. The atomized particles are completely filled at the moment of buffering and thrown out through the outlet, so that the morphology of the atomized particles thrown out by each guide channel remains intact and the particle size is consistent, which is beneficial to improving the consistency of the size of the atomized particles obtained by the atomization device and to ensuring the integrity of the particle morphology.

[0006] In some embodiments, the guide channel has a convex portion protruding along the circumference of the atomizing disk, and the minimum distance between the convex portion and the inlet is smaller than the minimum distance between the convex portion and the outlet.

[0007] In the above solution, by arranging the convex portion of the guide channel with an arc structure close to the inlet, the atomized particles in each guide channel can be buffered at the convex portion and form atomized particles with complete morphology and uniform size.

[0008] In some embodiments, the guide channel includes a first flow channel and a second flow channel connected in sequence, and a convex portion is formed at the intersection of the first flow channel and the second flow channel. In the axial direction, an arc trajectory formed by the orthographic projection of the first flow channel and an arc trajectory formed by the orthographic projection of the second flow channel form a hyperbola structure.

[0009] In the above solution, by setting the arc trajectories of the first flow channel and the second flow channel to a hyperbolic structure, the effectiveness of the atomization device in obtaining atomized particles of uniform size and complete morphology is further improved.

[0010] In some embodiments, the atomization device also includes an adjusting member, which is arranged on the outer wall surface of the atomization disk and is movably connected to the atomization disk so that the adjusting member and the atomization disk can switch between a first mating position and a second mating position; in the first mating position, the radial projection of the outlet does not overlap with the adjusting member, and in the second mating position, the radial projection of the outlet overlaps with the adjusting member to reduce the area size of the outlet.

[0011] In the above scheme, an adjusting member movably connected to the outer wall surface is provided on the atomizing disk, so that the adjusting member and the atomizing disk can be switched between a first matching position and a second matching position, so as to change the size of the atomized particles ejected from the outlet by adjusting the size of the outlet area, which is beneficial to improving the versatility and flexible use of the atomizing device and helping to reduce costs.

[0012] In some embodiments, the adjusting member includes a guide sleeve, which is annular and has a diameter larger than a diameter of the atomizing disk. The guide sleeve is disposed on the atomizing disk and connected to the outer wall surface. The guide sleeve includes a sleeve wall, and the sleeve wall has a plurality of sleeve holes extending radially therethrough, and the area size of at least some of the sleeve holes is smaller than the area size of the outlet.

[0013] In the above solution, the guide sleeve can be sleeved on the atomizing disk and connected to the outer wall surface to achieve the effect of being able to adjust the outlet size. The structure is simple, easy to process, and convenient to assemble.

[0014] In some embodiments, the sleeve hole includes a first hole and a second hole, the area size of the first hole is smaller than the area size of the outlet, the area size of the second hole is not smaller than the area size of the outlet, and the guide sleeve is movably connected to the outer wall surface along the circumference of the atomizing disk; in a first matching position, the guide sleeve is arranged on one side of the outlet in the radial direction, and the orthographic projection of the outlet in the radial direction falls into the second hole, and in a second matching position, the orthographic projection of the second hole in the radial direction falls into the outlet.

[0015] In the above solution, the guide sleeve is movably connected to the outer wall surface along the circumferential direction, so that the guide sleeve and the atomizing disk can be switched between the first matching position and the second matching position, which is simple to operate and easy to implement.

[0016] In some embodiments, the guide sleeve is movably connected to the outer wall surface along the axial direction. In a first matching position, the guide sleeve is arranged on one side of the outlet along the axial direction. In a second matching position, the radial projection of the sleeve hole falls into the outlet.

[0017] In the above solution, the guide sleeve is movably connected to the outer wall surface along the axial direction, so that the guide sleeve and the atomizing disk can be switched between the first matching position and the second matching position, which is simple to operate and helps to reduce processing costs.

[0018] In some embodiments, the outer wall surface has a strip-shaped guide portion, and the guide sleeve can be movably connected to the outer wall surface along an extension direction of the strip-shaped guide portion.

[0019] In the above solution, it is helpful to ensure the stability of the guide sleeve and the atomizing disk being able to switch between the first matching position and the second matching position.

[0020] In some embodiments, the number of guide sleeves is set to two or more, wherein the area ratio of at least part of the sleeve holes on one guide sleeve to the outlet is 4 / 5, and the area ratio of at least part of the sleeve holes on another guide sleeve to the outlet is 3 / 5.

[0021] In the above solution, the atomizing device can obtain atomized particles of at least three different sizes, which is conducive to further reducing costs and improving the versatility of the atomizing device.

[0022] In some embodiments, the radial projection of the outlet is a circular structure.

[0043] With the rapid development of the lithium battery industry, the production process of lithium battery positive and negative electrodes has become one of the most important links, namely the spray drying process. However, the shape of the dry particles sprayed by the existing spray equipment is easily damaged and the size is uneven.

[0044] Based on the above technical problems, the embodiment of the present application provides an atomizing device, which makes the atomized particles thrown out by the atomizing device have uniform size and complete particle morphology by setting the guide channel as a structure whose orthographic projection in the axial direction extends in an arc-shaped trajectory. The atomizing device can be produced and sold separately as an independent component. At the same time, it can also be used in spraying equipment and as a component of the spraying equipment and used in vehicles, which can help improve the uniformity of the spraying of the spraying equipment.

[0045] Please also read Figures 1 to 3, the embodiment of the present application provides an atomization device, including an atomization disk 10 and an adapter 20. The atomization disk 10 has an inner wall surface 101 and an outer wall surface 102 that are relatively arranged along its own radial direction X. A plurality of guide channels 11 are arranged on the atomization disk 10, and the plurality of guide channels 11 are distributed around the center of the atomization disk 10 at intervals. One end of the guide channel 11 passes through the inner wall surface 101 to form an inlet 111, and the other end passes through the outer wall surface 102 to form an outlet 112. The adapter 20 is arranged on the atomization disk 10 and encloses the atomization disk 10 to form a feed cavity 10a, and the feed cavity 10a is connected to each guide channel 11. Among them, along the axial direction Y of the atomization disk 10, the orthographic projection of the guide channel 11 extends along an arc trajectory.

[0046] The atomizing device provided in the embodiment of the present application sets the orthographic projection of the guide channel 11 on the axial direction Y as a structure extending along an arc trajectory, so that the slurry in the feed chamber 10a enters the guide channel 11 and is atomized to form atomized particles, and the atomized particles are buffered to temporarily stay in the guide channel 11. The atomized particles are completely filled at the moment of buffering and then thrown out through the outlet 112, so that the morphology of the atomized particles thrown out by each guide channel 11 remains intact and the particle size is consistent, which is beneficial to improving the consistency of the size of the atomized particles obtained by the atomizing device and to ensuring the integrity of the particle morphology.

[0047] Optionally, the atomizing disk 10 may be a disc-shaped structure. Of course, the atomizing disk 10 may also be a square structure, as long as the slurry in the feed chamber 10a can be dispersed from the inlet 111 to the guide channel 11 by centrifugal force to achieve an atomization effect.

[0048] Optionally, the feed chamber 10a is configured as a circular ring structure, which helps to ensure uniformity of the slurry entering each guide channel 11 .

[0049] Along the axial direction Y of the atomizer disk 10 , the orthographic projection of the guide channel 11 extends along an arc trajectory, wherein the direction of the arc trajectory presented by the orthographic projection of each guide channel 11 on the axial direction Y remains consistent to form a radial structure centered on the adapter 20 .

[0050] By setting the orthographic projection of the guide channel 11 on the axial direction Y as an arc trajectory, the slurry is atomized in the guide channel 11 to form particles uniformly. The slurry in the feed chamber 10a flows into the guide channel 11 from the inlet 111 under the action of centrifugal force and gravity, collides with the arc-shaped wall of the guide channel 11 and is buffered at the bend of the guide channel 11 with an arc structure. The atomized particles are temporarily stopped at this buffer position. At the moment of buffering, the atomized particles are completely filled by the atomized particles that enter this bend later to obtain atomized particles with complete morphology, which are then thrown out from the outlet 112. The size of the atomized particles thrown out from each outlet 112 is consistent.

[0051] The turning point of the guide channel 11 refers to the vertex position of an arc track. For example, an arc track with a semicircular structure has one vertex, and an arc track with a wave structure has multiple vertices.

[0052] Optionally, the arc-shaped trajectory of the guide channel 11 provided in the embodiment of the present application in the axial direction Y may be a semicircular structure, and of course, may also be a wavy structure.

[0053] When the guide device rotates at high speed, the arc trajectory of the guide channel 11 is opposite to the rotation direction of the atomizing disk 10, so that the slurry can better collide with the inner wall of the guide channel 11 and be buffered to form atomized particles with complete morphology and uniform size.

[0054] By providing a plurality of guide channels 11 , it is helpful to improve the efficiency of atomized particles being thrown out by the plurality of guide channels 11 , thereby helping to improve the atomization efficiency of the atomization device.

[0055] Optionally, the adapter 20 is disposed at the center of the atomizing disk 10 to ensure high efficiency of the rotation of the atomizing disk 10 .

[0056] Optionally, the adapter 20 can be configured as an axial hole, and the motor is connected to the atomizing disk 10 through the axial hole to drive the atomizing disk 10 to rotate. Of course, the adapter 20 can also be configured as a shaft sleeve, and is connected to the motor through the shaft sleeve.

[0057] Optionally, the atomizer disk 10 may include an upper cover and a bottom plate. The upper cover may be configured as a ring structure with a first through hole, and the bottom plate may be configured as a ring structure with a second through hole. The aperture size of the first through hole is larger than the aperture size of the second through hole. When the adapter 20 is configured as an axial hole, the aperture size of the second through hole is the same as that of the axial hole. The main shaft of the motor passes through the second through hole, the axial hole and the first through hole in sequence to connect with the atomizer disk 10 and drive the atomizer disk 10 to rotate. At this time, the bottom plate, the main shaft and the upper cover enclose a feed chamber 10a that can be connected to the outside world through the first through hole. Slurry can be put into the feed chamber 10a through the first through hole so that the slurry enters the guide channel 11 from the feed chamber 10a.

[0058] Optionally, the guide channel 11 can be formed by isolating isolation blocks with equal circumferential Z intervals, equal axial Y heights and the same shape, which is conducive to ensuring the uniformity of particles ejected from the slurry outlet 112. Optionally, the isolation blocks are connected between the upper cover and the bottom plate and have an arc-shaped structure.

[0059] Optionally, the radial X dimension of the guide channel 11 is smaller than the thickness of the isolation block, so as to increase the intensity of the slurry impacting the isolation block, which is beneficial to increasing the service life of the atomization device.

[0060] Optionally, a plurality of guide channels 11 may be provided on the atomizing disk 10 , each of the guide channels 11 extends from the adapter portion 20 to the edge, and the outlet 112 is provided at the peripheral edge of the atomizing disk 10 .

[0061] The atomizing device provided in the embodiment of the present application can be connected to the motor through the adapter 20. The motor provides power for the atomizing device to drive the atomizing disk 10 to rotate at high speed. The slurry in the feed chamber 10a flows into the guide channel 11 from the inlet 111. Since the atomizing disk 10 is rotating at high speed as a whole, the slurry is stretched into atomized particles in the guide channel 11. Moreover, the slurry can form atomized particles of uniform size and shape in the guide channel 11 with an arc structure, and then be thrown out from the outlet 112 to contact and combine with the hot air to form dry particles of the same size and shape.

[0062] Optionally, the atomizing disk 10 may be made of titanium alloy material, which has less wear when rotating at high speed, has a long service life, and is also conducive to achieving a higher linear speed and rotation speed, thereby helping to improve the atomization efficiency of the atomizing device.

[0063] Please continue reading Figure 1 and Figure 2 In some embodiments, the guide channel 11 has a convex portion 11 c protruding along the circumferential direction Z of the atomizing disk 10 , and the minimum distance between the convex portion 11 c and the inlet 111 is smaller than the minimum distance between the convex portion 11 c and the outlet 112 .

[0064] By arranging the convex portion 11 c of the guide channel 11 with an arc structure close to the inlet 111 , the slurry in each guide channel 11 can be buffered at the convex portion 11 c and form atomized particles with the same size and shape.

[0065] Optionally, the number of the protrusions 11 c is set to one to avoid clogging of the slurry in the guide channel 11 , thereby helping to reduce the retention of the slurry in the guide channel 11 .

[0066] In some embodiments, the guide channel 11 includes a first flow channel 11a and a second flow channel 11b which are connected in sequence. The convex portion 11c is formed at the intersection of the first flow channel 11a and the second flow channel 11b. In the axial direction Y, the arc trajectory formed by the orthographic projection of the first flow channel 11a and the arc trajectory formed by the orthographic projection of the second flow channel 11b form a hyperbola structure.

[0067] By setting the arc trajectories of the first flow channel 11a and the second flow channel 11b to be hyperbolic structures, the effectiveness of the atomization device in obtaining atomized particles of uniform size and complete morphology is further improved.

[0068] The length, curvature and other parameters of the first flow channel 11a and the second flow channel 11b can be calculated according to the shape and structure of the atomizer disk 10 to obtain two arc trajectories with a hyperbolic structure, and the two hyperbolas are placed at corresponding positions to intersect, and the intersection is the convex portion 11c.

[0069] The specific use process of the atomization device is that the atomization disk 10 rotates under the drive of the motor. When it reaches the fastest speed, the slurry is pumped into the feed chamber 10a. The slurry is evenly injected into the first flow channel 11a from the feed chamber 10a under the action of centrifugal force and gravity, and then passes through the convex part 11c for a short stay to form atomized particles with complete morphology, and then quickly rolls and rubs into the second flow channel 11b, and finally is thrown out from the outlet 112.

[0070] like Figure 3 As shown, in some embodiments, the atomizing device further comprises an adjusting member, which is disposed on the outer wall surface 102 of the atomizing disk 10 and is movably connected to the atomizing disk 10, so that the adjusting member and the atomizing disk 10 can be switched between a first matching position and a second matching position. In the first matching position, the orthographic projection of the outlet 112 along the radial direction X does not overlap with the adjusting member, and in the second matching position, the orthographic projection of the outlet 112 along the radial direction X overlaps with the adjusting member, so as to reduce the area size of the outlet 112.

[0071] By providing an adjusting member movably connected to the outer wall surface 102 on the atomizing disk 10, the adjusting member and the atomizing disk 10 can be switched between a first matching position and a second matching position, so as to change the size of the atomized particles ejected from the outlet 112 by adjusting the area size of the outlet 112, thereby improving the versatility and flexible use of the atomizing device and reducing costs.

[0072] Optionally, the adjusting member can be configured as a shielding member connected to the outer wall surface 102 near the outlet 112 of the atomizing disk 10, and the number of shielding members is set to be the same as the number of outlets 112, and one shielding member is correspondingly provided for each outlet 112 to ensure that the outlet 112 size of each outlet 112 is set to be the same.

[0073] Optionally, the shielding member can be detachably connected to the outer wall surface 102 by fasteners such as bolts, studs, screws and pins, and the number of fasteners can be set to two or more. In the first mating position, the orthographic projection of the outlet 112 along the radial direction X does not overlap with the shielding member, so that the atomized particles ejected from the outlet 112 are consistent with the size of the outlet 112. At least some of the fasteners are removed, so that the shielding member moves on the outer wall surface 102 to switch from the first mating position to the second mating position, and the orthographic projection of the outlet 112 along the radial direction X overlaps with the shielding member, that is, the shielding member blocks part of the outlet 112, reducing the area size of the outlet 112, so as to obtain atomized particles smaller than the area size of the outlet 112.

[0074] Optionally, the shielding member may be configured as an arc-shaped structure having a hole of the same shape as the outlet 112 , so as to facilitate a fitting connection with the outer wall surface 102 and ensure the uniformity of the shape of the atomized particles ejected from the outlet 112 at the second mating position.

[0075] The atomizing device provided in the embodiment of the present application is beneficial to improving versatility and flexibility of use by providing an adjusting piece. When atomized particles of different sizes need to be obtained, this can be achieved by using an atomizing device provided with an adjusting piece. There is no need to produce a plurality of atomizing devices with different sizes of outlets 112, which is beneficial to reducing processing costs. In addition, the adjusting piece is movably connected to the atomizing disk 10. It is only necessary to adjust the relative position of the adjusting piece and the atomizing disk 10 to change the size of the outlet 112. No assembly is required, which is beneficial to improving operating efficiency and reducing operating difficulty.

[0076] Please continue to participate, Figure 3 In some embodiments, the adjusting member includes a guide sleeve 31, which is annular and has a diameter greater than a diameter of the atomizing disk 10. The guide sleeve 31 is sleeved on the atomizing disk 10 and connected to the outer wall surface 102. The guide sleeve 31 includes a sleeve wall 311, and the sleeve wall 311 has a plurality of sleeve holes 311a extending through the sleeve wall along the radial direction X, and the area size of at least some of the sleeve holes 311a is smaller than the area size of the outlet 112.

[0077] The adjusting member is provided as the guide sleeve 31, which is sleeved on the atomizing disk 10 and connected to the outer wall surface 102, so as to be able to adjust the area size of the outlet 112. The structure is simple, easy to process, and convenient to assemble.

[0078] Furthermore, the radial X dimension of the guide sleeve 31 is set to be larger than the radial X dimension of the atomizing disk 10 , which helps to ensure the effectiveness of the guide sleeve 31 being able to be sleeved on the outer wall surface 102 of the atomizing disk 10 .

[0079] In order to reduce the gap between the outlet 112 and the sleeve hole 311a in the radial direction X to ensure that the atomized particles can enter the sleeve hole 311a from the outlet 112 and be thrown out from the sleeve hole 311a, the radial X dimension of the guide sleeve 31 can be set to be equal to the sum of the radial X dimension of the atomizing disk 10 and the thickness dimension of the guide sleeve 31, which is conducive to ensuring that the guide sleeve 31 and the outer wall surface 102 of the atomizing disk 10 fit more closely.

[0080] The sleeve wall 311 of the guide sleeve 31 has a plurality of sleeve holes 311a that penetrate along the radial direction X. The area size of at least some of the sleeve holes 311a is smaller than the area size of the outlet 112. Optionally, the area size of all the sleeve holes 311a can be set to be the same and smaller than the area size of the outlet 112. Of course, the area size of at least some of the sleeve holes 311a can also be equal to or larger than the area size of the sleeve holes 311a. The specific setting can be made according to the way the guide sleeve 31 moves with the outer wall surface 102.

[0081] In some embodiments, the sleeve hole 311a includes a first hole and a second hole, the area size of the first hole is smaller than the area size of the outlet 112, the area size of the second hole is not smaller than the area size of the outlet 112, and the guide sleeve 31 is movably connected to the outer wall surface 102 along the circumferential direction Z of the atomizing disk 10. In the first matching position, the guide sleeve 31 is arranged on one side of the outlet 112 along the radial direction X, and the positive projection of the outlet 112 along the radial direction X falls into the second hole. In the second matching position, the positive projection of the second hole along the radial direction X falls into the outlet 112.

[0082] By arranging in this way, the guide sleeve 31 can be movably connected to the outer wall surface 102 along the circumferential direction Z, so that the guide sleeve 31 and the atomizing disk 10 can be switched between the first matching position and the second matching position, which is simple to operate and easy to implement.

[0083] Optionally, the first hole and the second hole on the guide sleeve 31 may be arranged at intervals. Of course, they may also be arranged according to a certain rule, and may be specifically set according to the position of the outlet.

[0084] In the first mating position, the guide sleeve 31 is arranged on one side of the outlet 112 along the radial direction X, the second hole is arranged opposite to the outlet 112, and the first hole is arranged opposite to the outer wall surface 102, so that the atomized particles can be thrown out through the outlet 112 and the second hole in turn.

[0085] Optionally, the area size of the first hole is equal to the area size of the outlet 112, and the shape of the first hole is set to be the same as the shape of the outlet 112. Of course, the area size of the first hole can also be larger than the area size of the outlet 112. In this case, the shape of the first hole can be set to be the same as the shape of the outlet 112, or it can be set to be different. It is only necessary to ensure that the positive projection of the second hole along the radial direction X falls into the outlet 112.

[0086] In the second mating position, the guide sleeve 31 is arranged on one side of the outlet 112 along the radial direction X, the first hole is arranged opposite to the outlet 112, and the second hole is arranged opposite to the outer wall 102, so that the atomized particles can be thrown out through the outlet 112 and the first hole in turn to obtain atomized particles of the required size.

[0087] Optionally, the guide sleeve 31 and the outer wall surface 102 can be set to be frictionally and slidingly connected along the circumferential direction Y. Of course, the sleeve wall 311 of the guide sleeve 31 can be provided with a first thread on the side close to the outer wall surface 102 along the radial direction X, and the outer wall surface 102 is provided with a second thread. The first thread and the second thread are matched and connected to realize that the guide sleeve 31 can be movably connected to the outer wall surface 102 along the circumferential direction Z.

[0088] like Figure 3 As shown, in some embodiments, the guide sleeve 31 is movably connected to the outer wall 102 along the axial direction Y. In a first mating position, the guide sleeve 31 is arranged on one side of the outlet 112 along the axial direction Y. In a second mating position, the orthographic projection of the sleeve hole 311a along the radial direction X falls into the outlet 112.

[0089] By arranging in this way, the guide sleeve can be movably connected to the outer wall surface 102 along the axial direction Y, so that the guide sleeve 31 and the atomizing disk can be switched between the first matching position and the second matching position, which is easy to operate and helps to reduce processing costs.

[0090] In the first mating position, the guide sleeve 31 is arranged on one side of the outlet 112 along the axial direction Y, and the center of the sleeve hole 311a and the center of the outlet 112 are located on the same axis, so that when the guide sleeve 31 moves to the second mating position, the positive projection of the sleeve hole 311a along the radial direction X can fall into the outlet 112.

[0091] By configuring in this manner, the sleeve holes 311a on the guide sleeve 31 can all be configured to be holes with an area smaller than the outlet 112 and with the same area size, which is convenient for processing and helps reduce processing costs.

[0092] Optionally, the guide sleeve 31 and the outer wall surface 102 can be set to be frictionally and slidingly connected along the axial direction Y. Of course, the sleeve wall 311 of the guide sleeve 31 can also be provided with fasteners that are detachably connected to the outer wall surface 102, and the guide sleeve 31 can be movably connected to the outer wall surface 102 along the axial direction Y by disassembling and assembling the fasteners.

[0093] In some embodiments, the outer wall surface 102 has a strip-shaped guide portion, and the guide sleeve 31 can be movably connected to the outer wall surface 102 along an extension direction of the strip-shaped guide portion.

[0094] By configuring in this manner, it is possible to ensure that the guide sleeve 31 and the atomizing disk 10 can switch between the first matching position and the second matching position with ease and stability.

[0095] Optionally, the strip guide portion can be configured as a slide rail connected to the outer wall surface 102, and the side of the sleeve wall 311 of the guide sleeve 31 close to the outer wall surface 102 along the radial direction X can be configured as a slider, and the slide rail and the slider move in coordination. Optionally, the slide rail can be a T-shaped slide rail, and the slider can be a T-shaped slider.

[0096] Optionally, the strip guide portion may be configured as a strip hole penetrating the outer wall surface 102 , and a side of the sleeve wall 311 of the guide sleeve 31 close to the outer wall surface 102 along the radial direction X may be configured as a pin shaft, and the pin shaft can move in the strip hole.

[0097] Optionally, the strip-shaped guide portion may extend along the axial direction Y, and of course, may also extend along the circumferential direction Z.

[0098] In some embodiments, the number of guide sleeves 31 is set to two or more, wherein the area ratio of at least part of the sleeve holes 311a on one guide sleeve 31 to the outlet 112 is 4 / 5, and the area ratio of at least part of the sleeve holes 311a on another guide sleeve 31 to the outlet 112 is 3 / 5.

[0099] By configuring in this manner, the atomizing device can obtain atomized particles of at least three different sizes, which is beneficial for further reducing costs and improving the versatility of the atomizing device.

[0100] like Figure 3 As shown, a guide sleeve 31 may be provided on one side of the outlet along the axial direction Y, and a guide sleeve 31 may also be provided on the other side. When it is necessary to obtain atomized particles with an area ratio of 4 / 5 at the outlet 112, it is only necessary to move the guide sleeve 31 with the sleeve hole 311a along the axial direction Y.

[0101] Optionally, the number of the guide sleeves 31 may be set to three or more, and the area ratio of at least part of the sleeve holes 311a on the guide sleeve 31 to the outlet 112 may also be set as required.

[0102] Optionally, by setting the number of guide sleeves 31 to two, the volume of the atomization device can be reduced, and atomized particles of different sizes can be obtained by replacing the guide sleeves 31, which is simple and easy to operate.

[0103] In some embodiments, the orthographic projection of the outlet 112 on the radial direction X is a circular structure.

[0104] By configuring in this manner, the atomized particles ejected from the outlet 112 can be in a circular structure, so as to be easily contacted with hot air and evaporated to form dry particles.

[0105] Optionally, the orthographic projection of the inlet 111 in the radial direction X is a circular structure, and the cross-sectional dimension of the flow guide channel 11 is a circular structure.

[0106] In a second aspect, an embodiment of the present application provides a spraying device, comprising an atomizing device and a motor as in any of the above embodiments. The motor is connected to the adapter 20 and is configured to drive the atomizing device to rotate.

[0107] Since the atomizing device provided in the embodiment of the present application can make the atomized particles uniform in size and complete in shape, the spraying equipment including the atomizing device is helpful in improving the uniformity of spraying.

[0108] Optionally, the atomizing device is mounted on the main shaft of the motor through the adapter 20 , and the motor drives the entire atomizing disk 10 to rotate at high speed through the main shaft to atomize the slurry entering the atomizing disk 10 from the feed chamber 10a.

[0109] Optionally, the rotation direction of the atomizer disk 10 is set to be the same as the protruding direction of the convex portion 11c of the guide channel 11, that is, it is set opposite to the arc trajectory of the guide channel 11, which is beneficial to increase the air flow speed, that is, increase the relative rotation speed of the atomizer disk 10, and further improve the atomization effect.
