[0039] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0040] The spray nozzle 100 according to the embodiment of the present application is arranged on a granulator, and the spray nozzle 100 comprises a bottom plate 1, a baffle assembly 2 and an adjusting assembly 3. The bottom plate 1 is provided with a plurality of water spraying holes 11, and the plurality of water spraying holes 11 are arranged at intervals in the height direction of the bottom plate 1. The baffle assembly 2 is provided with one water outlet hole 211 or a plurality of water outlet holes 211 arranged at intervals in the height direction of the bottom plate 1. The side end face of the baffle assembly 2 facing the bottom plate 1 is attached to the bottom plate 1,

[0041] The adjusting assembly 3 is arranged on the bottom plate 1, and the adjusting assembly 3 is connected with the baffle 21. The adjusting assembly 3 moves the baffle assembly 2 in the height direction of the bottom plate 1 to adjust the size change of the flow area of the water outlet hole 211 and the water spraying hole 11 in the thickness direction of the bottom plate 1.

[0042] The spray nozzle 100 according to the embodiment of the present application can adjust the size of the water outlet to obtain metal particles with most of the particle sizes in the range of 3-50 mm.

[0043] As shown in Figure 1 and Figure 2 The spray nozzle 100 according to the embodiment of the present application is arranged on a granulator, and the spray nozzle 100 comprises a connecting pipe 8, a square round pipe 9 and a support seat 10. The spray nozzle 100 is arranged below the dispersing device 200 and the chute 300 and at the liquid surface of the granulation tank 400 through the support seat 10. After the molten metal flows out of the chute 300, it impacts the dispersing device 200 and falls into the water tank below in a scattered state. The granulation tank 400 is filled with a large amount of water, so that the molten metal can be rapidly cooled and solidified during entering the water tank. The spray nozzle 100 directly faces the falling molten metal and sprays high-pressure water to impact the molten metal, so that the molten metal is rapidly solidified and fragmented to form metal particles with a certain particle size range.

[0044] The height direction of the bottom plate 1 is the up-down direction, the extension direction of the bottom plate 1 is the left-right direction, the bottom plate 1 is provided with a plurality of water injection holes 11, the front end of the bottom plate 1 is connected with a square round pipe 9 of a granulator, and the square round pipe 9 is suitable for supplying water to the bottom plate 1, and the water is injected from the water injection holes 11 of the bottom plate 1.

[0045] The rear end surface of the bottom plate 1 is matched with the front end surface of the baffle assembly 2, the water injection holes 11 of the bottom plate 1 extend along the front-rear direction, the water outlet holes 211 of the baffle assembly 2 extend along the front-rear direction, and the baffle assembly 2 moves in the up-down direction to make the water injection holes 11 and the water outlet holes 211 communicate or close.

[0046] The adjusting assembly 3 is connected with the bottom plate 1, and the output end of the adjusting assembly 3 is connected with the baffle 21, the adjusting assembly 3 moves the baffle 21 in the up-down direction to change the size of the water outlet, that is, to change the size of the communication area of the water injection holes 11 and the water outlet holes 211 in the front-rear direction, and then to adjust the water flow of the water outlet.

[0047] For example, the number of the water outlet holes 211 on the baffle assembly 2 is one, the number of the water injection holes 11 on the bottom plate 1 is two, the two water injection holes 11 are arranged in the up-down direction, when the baffle assembly 2 moves to the uppermost position, the water outlet hole 211 on the baffle 21 is completely communicated with the upper water injection hole 11, that is, the upper water injection hole 11 is not blocked by the baffle assembly 2, and the lower water injection hole 11 is not blocked by the baffle assembly 2, at this time, the flow of the water injection nozzle is the largest. The adjusting assembly 3 adjusts the downward movement of the baffle assembly 2, at this time, the lower water injection hole 11 is gradually blocked by the downward movement of the baffle assembly 2, at the same time, the communication area of the upper water injection hole 11 and the water outlet hole 211 is gradually reduced when the baffle assembly 2 moves downward, until the water injection holes 11 on the bottom plate 1 are completely blocked by the baffle assembly 2, and then the size of the water outlet of the water injection nozzle 100 is steplessly adjusted, and then the water injection amount of the water injection nozzle 100 is adjusted.

[0048] The size of the water injection hole 11 is slightly smaller than the size of the water outlet hole 211, so that the baffle assembly 2 does not block the water injection hole 11 when the baffle assembly 2 is at the uppermost position.

[0049] The water injection nozzle 100 of the embodiment of the utility model adjusts the relative position of the baffle assembly 2 and the bottom plate 1 in the up-down direction by setting the adjusting assembly 3, adjusts the size of the communication area of the water injection hole 11 and the water outlet hole 211 or the size of the area blocked by the baffle assembly 2, that is, adjusts the size of the water outlet of the water injection nozzle 100, adjusts the flow of different metal liquid columns, and obtains metal particles with most particle sizes in the range of 3-50 mm. Further, the shapes of the water injection hole 11 and the water outlet hole 211 are the same, so as to improve the stability of the stepless adjustment of the water amount.

[0050] In some embodiments, the baffle assembly 2 includes a baffle 21 and a guide groove plate 22. The side end face of the baffle 21 facing the bottom plate 1 is in contact with the bottom plate 1. Guide groove plates 22 connected to the bottom plate 1 are provided on both sides of the baffle 21. Guide grooves 221 extending along the height direction of the bottom plate 1 are provided on both sides of the baffle 21 facing the baffle 21. The baffle 21 extends into the guide grooves 221 on both sides in the extending direction of the bottom plate 1.

[0051] Adjustment component 3 is connected to baffle 21 to move baffle 21 in the height direction of base plate 1. The front end face of baffle 21 is in contact with the rear end face of base plate 1.

[0052] Specifically, such as Figures 1 to 8 As shown, the rear end of the base plate 1 is connected to the guide plate 22, and there are two guide plates 22. The two guide plates 22 are arranged relatively spaced in the left and right directions. The left end of the baffle 21 extends into the guide groove 221 of the left guide plate 22, and the right end of the baffle 21 extends into the guide groove 221 of the right guide plate 22. The baffle 21 is connected to the adjustment component 3. The adjustment component 3 drives the baffle 21 to move in the up and down direction, and the guide groove 221 is adapted to limit the movement of the baffle 21 in the up and down direction. For example, the guide groove 221 extends in the up and down direction, the left end of the baffle 21 matches the guide groove 221 of the left guide plate 22, and the right end of the baffle 21 matches the inner wall surface of the guide groove 221 of the right guide plate 22. Thus, when the baffle 21 moves in the up and down direction, the left and right directions of the baffle 21 are limited to prevent the baffle 21 from moving out of the range in the left and right directions, and to prevent the water spray hole 11 from spraying water directly.

[0053] Alternatively, the guide groove 221 extends in the vertical direction, with the left end of the baffle 21 contacting the guide groove 221 of the left guide plate 22, and the right end of the baffle 21 contacting the inner wall of the guide groove 221 of the right guide plate 22, so as to avoid excessive movement of the baffle 21 in the left and right directions.

[0054] The water outlet 211 is set on the baffle 21. For example, the baffle 21 has one water outlet 211 and the bottom plate 1 has two water spray holes 11. The two water spray holes 11 are spaced apart in the vertical direction. When the baffle 21 is moved to the top, the water outlet 211 on the baffle 21 is completely connected with the water spray hole 11 above. That is, the water spray hole 11 above is not blocked by the baffle 21, and the water spray hole 11 below is in a state where it is not blocked by the baffle 21. At this time, the flow rate of the spray nozzle is the maximum. When the adjusting component 3 adjusts the baffle 21 to move down, the grouting of the lower water spray hole 11 is gradually blocked when the baffle 21 moves down. At the same time, when the baffle 21 moves down, the communication area between the upper water spray hole 11 and the water outlet hole 211 also gradually decreases until the water spray hole 11 on the bottom plate 1 is completely blocked by the baffle 21, thereby realizing stepless adjustment of the outlet size of the spray nozzle 100, and thus adjusting the spray volume of the spray nozzle 100.

[0055] The spray nozzle 100 of the embodiment of the utility model, through setting guide groove plate 22 and baffle 21, the baffle 21 is positioned in the left and right direction of baffle 21 when moving up and down, avoid baffle 21 to be separated from the bottom plate 1 and the left and right direction of baffle 21 in the front and back direction by water pressure, avoid baffle 21 to be separated from the bottom plate 1 and avoid baffle 21 to move left and right, improve the stability and safety of baffle 21 moving in the up and down direction.

[0056] In some embodiments, the spray nozzle 100 further comprises a reinforcing water guide plate 4 extending along the extension direction of the bottom plate 1,

[0057] The reinforcing water guide plate 4 is arranged on the top of the baffle 21, and the reinforcing water guide plate 4 is arranged above the water outlet hole 211,

[0058] Or, the reinforcing water guide plate 4 is arranged on the top of the baffle 21, and the reinforcing water guide plate 4 is arranged above the water outlet hole 211.

[0059] It can be understood that the top and bottom of the rear end surface of the baffle 21 are provided with the reinforcing water guide plate 4, and the reinforcing water guide plate 4 is arranged above the water outlet hole 211, or it can be understood that when the number of water outlet holes 211 is multiple, the reinforcing water guide plate 4 is arranged above the uppermost water outlet hole 211, and when the number of water outlet holes 211 is one, the reinforcing water guide plate 4 is arranged above the water outlet hole 211, which increases the rigidity of the baffle 21 in the left and right directions, avoids the baffle 21 from being deformed by water pressure, and affects the sealing performance. At the same time, the water flowing out of the water outlet hole 211 is guided to avoid the water flowing out of the water outlet hole from spraying upward to impact the dispersing rod, and to avoid the water flowing to the dispersing rod to affect the stability of the dispersing rod.

[0060] Or, the top and bottom of the rear end surface of the baffle 21 are provided with the reinforcing water guide plate 4, and the reinforcing water guide plate 4 is arranged above the water outlet hole 211, or it can be understood that when the number of water outlet holes 211 is multiple, the reinforcing water guide plate 4 is arranged above the uppermost water outlet hole 211, and when the number of water outlet holes 211 is one, the reinforcing water guide plate 4 is arranged above the water outlet hole 211. Further, the water flowing out of the water outlet hole 211 is guided, and when the reinforcing water guide plate 4 is arranged on the baffle 21 in the up and down direction of the baffle 21, the reinforcing water guide plate 4 guides the water flowing out of the water outlet hole 211, avoids the water flowing out of the water outlet hole 211 from impacting the dispersing rod upward, and avoids too much water from flowing directly downward into the lower granulation tank 400, so that as much water as possible impacts the metal particles after impacting the dispersing rod, improves the efficiency and stability of metal granulation. At the same time, the reinforcing water guide plate 4 is arranged on the baffle 21 to improve the structural strength of the baffle 21.

[0061] That is, when the water outlet hole on the baffle 21 is only one, the upper and lower directions of the water outlet hole 211 are provided with the reinforced water guide plate 4 to guide the water flowing out of the water outlet hole 211, so that more water is directly flowed into the granulation tank 400 due to excessive kinetic energy loss of the water guided by the water outlet hole 211, thereby improving the granulation efficiency.

[0062] In some embodiments, the adjusting assembly 3 includes an adjusting rod 31, an adjusting seat 32 and a limiting piece 33, the baffle 21 is provided with a ring groove 212 away from the bottom plate 1, the adjusting seat 32 is connected with the bottom plate 1, the adjusting rod 31 is threadedly connected with the adjusting seat 32, and the adjusting rod 31 is connected with the limiting piece 33 by penetrating through the adjusting seat 32 and extending into the ring groove 212.

[0063] Specifically, as shown in Figures 1 to 8 the rear end surface of the baffle 21 is provided with a ring groove 212, the adjusting seat 32 is arranged at the upper end of the bottom plate 1, the adjusting rod 31 is threadedly connected with the adjusting seat 32, the adjusting rod 31 penetrates through the adjusting seat 32 and extends into the ring groove 212, and the part of the adjusting rod 31 in the ring groove 212 is sleeved with the limiting piece 33, when the baffle 21 needs to move in the up-down direction, the adjusting rod 31 can be rotated to move the adjusting rod 31 in the up-down direction relative to the adjusting seat 32, for example, when the adjusting rod 31 moves up and down, the limiting piece 33 is in contact with the inner wall surface of the ring groove 212, at this time, the adjusting rod 31 drives the baffle 21 to move up and down through the limiting piece 33, further, the outer periphery of the limiting piece 33 in contact with the inner wall surface of the ring groove 212 can be coated with lubricating oil to reduce the friction when the adjusting rod 31 drives the limiting piece 33 to move.

[0064] The spray nozzle 100 of the embodiment of the utility model, through the thread cooperation of the adjusting rod 31 and the adjusting seat 32, the precision of the baffle 21 adjusting in the up-down direction can be improved, and the baffle 21 is moved in the up-down direction through the rotation of the adjusting rod 31, so that the convenience of adjusting the position of the baffle 21 in the up-down direction is improved.

[0065] Further, the limiting piece 33 includes a clamping ring sleeved on the adjusting rod 31 and a stop screw, the stop screw is threadedly connected with the part of the adjusting rod 31 in the ring groove 212 through the clamping ring to fix the clamping ring and improve the stability of the limiting piece 33 in use.

[0066] Further, the clamping ring is threadedly connected with the adjusting rod 31 to provide axial force, and the stop screw prevents the clamping ring and the adjusting rod 31 from rotating relative to each other, so that the two are connected and fixed as a whole.

[0067] In some embodiments, the adjusting rod 31 penetrates the snap ring and protrudes a small section in the up-down direction, or it is understood that the adjusting rod 31 penetrates the limiting piece 33 and protrudes a small section downward in the up-down direction. When the baffle 21 needs to move in the upward direction, the adjusting rod 31 can be rotated to move the adjusting rod 31 in the upward direction relative to the adjusting seat 32. For example, when the adjusting rod 31 moves upward, the limiting piece 33 contacts the inner wall surface of the ring groove 212. At this time, the adjusting rod 31 drives the baffle 21 to move upward through the limiting piece 33. Further, the outer periphery of the limiting piece 33 in contact with the inner wall surface of the ring groove 212 can be coated with lubricating oil to reduce the friction when the adjusting rod 31 drives the limiting piece 33 to move upward. For example, when the adjusting rod 31 moves downward, the adjusting rod 31 contacts the inner wall surface of the ring groove 212. At this time, the adjusting rod 31 directly drives the baffle 21 to move downward. Further, the outer periphery of the adjusting rod 31 in contact with the inner wall surface of the ring groove 212 can be coated with lubricating oil to reduce the friction when the adjusting rod 31 drives the baffle 21 to move downward.

[0068] Further, the adjusting assembly 3 further comprises a first locking piece 34. The first locking piece 34 is threadedly connected with the adjusting rod 31, and the first locking piece 34 is arranged at the end of the adjusting rod 31 away from the adjusting seat 32 and the baffle 21. The first locking piece 34 can be a lock nut. After the baffle 21 moves up and down, the lower end of the first locking piece 34 contacts the adjusting seat 32 and is pre-tightened to limit the adjusting rod 31.

[0069] In some embodiments, the water injection nozzle 100 further comprises a water blocking strip 5. The water blocking strip 5 is arranged at the top of the baffle 21 and the guide groove plate 22, or the water blocking strip 5 is arranged at the top of the baffle 21, and the water blocking strip 5 is arranged in the guide groove 221 of the guide groove plate 22 on both sides of the bottom plate 1 in the extension direction of the bottom plate 1.

[0070] Specifically, as shown in Figures 1 to 8 The water blocking strip 5 is arranged above the baffle 21. The water blocking strip 5 can be arranged at the top of the baffle 21 and the guide groove plate 22 to avoid the water between the baffle 21 and the bottom plate 1 from flowing out through the gap between them, thereby affecting the components above, for example, the chute 300. At the same time, the water blocking strip 5 can guide the water flow to the area below the water blocking strip.

[0071] Alternatively, the water blocking strip 5 is arranged above the baffle 21, and the left and right ends of the water blocking strip 5 are arranged in the guide grooves 221 of the guide groove plates 22 on both sides, so as to support and limit the water blocking strip 5, thereby preventing the water blocking strip from being separated from the bottom plate 1 or moving up and down during use. The water blocking strip guides the water between the baffle 21 and the bottom plate 1.

[0072] Meanwhile, the adjusting seat 32 is arranged above the water baffle 5, and the size of the adjusting seat 32 in the front-rear direction is greater than the size of the water baffle 5, thereby ensuring that the adjusting rod 31 smoothly passes through the adjusting seat 32 and the baffle 21 into the annular groove 212.

[0073] Meanwhile, the water baffle 5 is arranged between the two guide grooves 221 and at the top of the guide groove 221, and forms a reverse U-shaped water baffle structure with the guide groove 221, thereby preventing high-pressure water from being sprayed upward or to the left and right sides from the gap between the water nozzle bottom plate 1 and the baffle 21, and thereby making the water as much as possible to fall into the granulation area.

[0074] Further, the adjusting seat 32 can also have a certain guiding and limiting effect on the water guided by the water baffle 5, thereby avoiding water flow from impacting the dispersing rod upward beyond the preset range.

[0075] In some embodiments, the size of the water baffle 5 in the height direction of the bottom plate 1 is A, and 3mm≤A≤10mm, and the size of the water baffle 5 in the thickness direction of the bottom plate 1 is B, and 10mm≤B≤15mm.

[0076] Specifically, as shown in Figures 1 to 8 A can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm. When A is 10mm, the connecting area of the water baffle 5 with the bottom plate 1 is the largest, and the connecting stability of the water baffle 5 on the bottom plate 1 is the best.

[0077] When A is 3mm, the connecting area of the water baffle 5 with the bottom plate 1 is the smallest, and the connecting stability of the water baffle 5 on the bottom plate 1 is poor.

[0078] B can be 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm. When B is 10mm, the guiding effect of the water baffle 5 on the water flow is poor, but the impact force of the water flow is small, and the service life is long. When B is 15mm, the guiding effect of the water baffle 5 on the water flow is the highest, but the impact force of the water flow is large, and the service life is short, and needs to be checked and replaced in time.

[0079] In some embodiments, the water injection nozzle 100 further comprises a limiting water guide plate 6 extending along the height direction of the bottom plate 1. The two sides of the baffle plate 21 in the extension direction of the bottom plate 1 are provided with limiting water guide plates 6, and the limiting water guide plates 6 on the two sides are matched with the two side guide groove plates 22 respectively to limit the movement of the baffle plate 21 in the extension direction of the bottom plate 1. The limiting water guide plate 6 extends in the up-down direction. For example, the limiting water guide plate 6 is in contact with the two side guide groove plates 22 to avoid the left-right movement of the baffle plate 21 beyond the preset range. Alternatively, the limiting water guide plate 6 does not necessarily contact the guide groove plate, and there is a gap between the limiting water guide plate 6 and the guide groove plate 22. When the baffle plate 21 deviates left and right, the limiting water guide plate 6 can contact the guide groove plate 22, thereby limiting the left-right deviation of the baffle plate 21.

[0080] Specifically, as shown in Figures 1 to 8 the number of limiting water guide plates 6 is two, and the limiting water guide plates 6 are arranged in opposite directions on the left and right sides of the baffle plate 21. The limiting water guide plates 6 are matched with the left and right guide groove plates 22 respectively, for example, the left limiting water guide plate 6 is matched with the right end of the left guide groove plate 22, and the right limiting water guide plate 6 is matched with the left end of the right guide groove plate 22, thereby limiting and guiding the left and right movement of the baffle plate 21.

[0081] At the same time, the position of the limiting water guide plate 6 on the baffle plate 21 is located on the left and right sides of the water outlet hole 211, and the limiting water guide plate 6 has a certain thickness in the front-back direction, thereby guiding the water outlet of the water outlet hole 211 in the left-right direction when the water outlet hole 211 is watered. The main purpose of the limiting water guide plate 6 and the reinforcing water guide plate 4 is to increase the rigidity of the baffle plate 211 to avoid deformation of the plate, and at the same time to make the water impact the metal particles in the area below the dispersing rod as much as possible, that is, to make the water impact the dispersing area as much as possible, thereby improving the effect and stability of the granulation. At the same time, the rigidity of the baffle plate 21 in the up-down direction is enhanced to avoid deformation and improve the sealing performance.

[0082] In some embodiments, the water injection nozzle 100 further comprises a locking assembly 7, and the guide groove plate 22 on the two sides of the extension direction of the baffle plate 21 is provided with the locking assembly 7, or at least one guide groove plate 22 is provided with the locking assembly 7.

[0083] The locking assembly 7 comprises a locking piece 71 and a second locking piece 72. The locking piece 71 is connected with the baffle plate 21 through the guide groove plate 22, and the locking piece 71 is threadedly connected with the guide groove plate 22. The second locking piece 72 is threadedly connected with the locking piece 71, and the second locking piece 72 is arranged at the end of the locking piece 71 away from the guide groove plate 22 and the baffle plate 21.

[0084] Specifically, as shown in Figures 1 to 8As shown, the locking member 71 is threadedly connected with the guide groove plate 22, and the locking member 71 is in contact with the rear end surface of the baffle plate 21 through the guide groove plate 22, and then the locking member 71 compresses the baffle plate 21 in the front-rear direction, avoids the baffle plate 21 from moving up and down, and reduces the gap between the baffle plate 21 and the bottom plate 1 in the front-rear direction. The second locking member 72 is threadedly connected with the locking member 71, and when locked, the front end surface of the second locking member 72 is in contact with the rear end surface of the guide groove plate 22 and is pre-tightened to lock the locking member 71. The locking member 71 can be a locking bolt, and the second locking member 72 is a lock nut.

[0085] At least one locking assembly 7 is arranged on each of the left and right guide groove plates 22, or at least one locking assembly 7 is arranged on at least one guide groove plate 22, so as to increase or reduce the arrangement of the locking assembly 7 according to the actual situation.

[0086] Further, the number of the adjusting assemblies 3 is multiple, the number of the ring grooves 212 arranged on the baffle plate 21 is multiple, and the multiple adjusting assemblies 3 correspond to the ring grooves 212 of the baffle plate 21 one by one. Thus, the stability and safety of the adjusting assembly 3 adjusting the movement of the baffle plate 21 are improved.

[0087] After the spray nozzle 100 is installed in place, the height of the nozzle is adjusted according to the water pool liquid level, and the support seat 10 is welded and installed. When starting the granulation work, the second locking member 72 of the locking assembly 7 is loosened, and then the locking member 71 is loosened. Then, the first locking member 34 of the adjusting assembly 3 is loosened, at this time, the height of the baffle plate 21 in the up-down direction can be adjusted through the adjusting rod 31 of the adjusting assembly 3, and then the water spraying amount of the spray nozzle 100 is adjusted. After the adjustment is completed, the first locking member 34 of the adjusting assembly 3 is tightened, and then the locking member 71 of the locking assembly 7 is tightened, and then the second locking member 72 is tightened, so that the baffle plate 21 is tightly attached to the nozzle bottom plate 1, and the water leakage from the attachment surface of the two is reduced. At the same time in the adjusting process, part of the high-pressure water will be sprayed from the attachment surface of the baffle plate 21 and the nozzle bottom plate 1, and since the guide groove 221 and the water retaining strip 5 form a reverse U-shaped water retaining structure, the water is effectively prevented from being sprayed from the two sides or the upper side of the nozzle.
