Description

[0002] In the metal or alloy (including nickel iron) smelting process, metal granulation is a more advantageous process method. In principle, there are usually two types: impact splashing and water quenching. The impact splashing method is to pour or drop the molten metal vertically onto the granulation head, and the molten metal impacts the granulation head and splashes, falls into the water below the granulation head, and quickly cools and solidifies to form solid particles. The water quenching method is to spray the molten metal with a certain pressure of water when it is poured and falls, so that the molten metal is suddenly cooled and solidified and broken into fine particles.

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] The water jet nozzle 100 according to the embodiment of the present invention is arranged on the granulator, and the water jet nozzle 100 includes a bottom plate 1, a baffle assembly 2 and an adjustment assembly 3. The bottom plate 1 has a plurality of water jet holes 11, and the plurality of water jet holes 11 are arranged at intervals in the height direction of the bottom plate 1. The baffle assembly 2 is provided with a 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 end surface of the baffle assembly 2 facing the bottom plate 1 is in contact with the bottom plate 1.

[0041] The adjusting component 3 is arranged on the bottom plate 1 and connected to the baffle 21. The adjusting component 3 enables the baffle component 2 to move in the height direction of the bottom plate 1 to adjust the size change of the flow area connecting the water outlet hole 211 and the water spray hole 11 in the thickness direction of the bottom plate 1.

[0042] The water jet nozzle 100 of the embodiment of the present invention can adjust the size of the water outlet to obtain most of the metal particles with a particle size within the range of 3 to 50 mm.

[0043] like Figure 1 and Figure 2 As shown, the water jet nozzle 100 is arranged on the granulator, and the water jet nozzle 100 includes a connecting pipe 8, a square and round pipe 9 and a support seat 10, and the water jet nozzle 100 is arranged below the scattering device 200 and the chute 300 through the support seat 10, at the liquid surface of the granulation water pool 400. After the molten metal flows out of the chute 300, it hits the scattering device 200 and falls into the water pool below in a scattered state. The granulation water pool 400 contains a large amount of water, so that the molten metal can be quickly cooled and solidified in the process of entering the water pool. The water jet nozzle 100 faces the falling molten metal and sprays high-pressure water to impact it, so that it quickly solidifies and breaks, forming metal particles of a certain size range.

[0044] The height direction of the bottom plate 1 is the up-down direction, and the extension direction of the bottom plate 1 is the left-right direction. The bottom plate 1 has a plurality of water spray holes 11. The front end of the bottom plate 1 is connected to the square tube 9 of the granulator. The square tube 9 is suitable for supplying water to the bottom plate 1, and the water is sprayed out from the water spray holes 11 of the bottom plate 1.

[0045] The rear end face of the base plate 1 fits with the front end face of the baffle assembly 2, the water spray hole 11 of the base plate 1 extends in the front-to-back direction, the water outlet hole 211 of the baffle assembly 2 extends in the front-to-back direction, and the baffle assembly 2 moves in the up-and-down direction to connect or close the water spray hole 11 and the water outlet hole 211.

[0046] The adjusting component 3 is connected to the bottom plate 1, and the output end of the adjusting component 3 is connected to the baffle 21. The adjusting component 3 moves the baffle 21 in the up and down directions to change the size of the water outlet, that is, to change the size of the connecting area between the water spray hole 11 and the water outlet hole 211 in the front and back directions, thereby adjusting the water output of the water outlet.

[0047] For example, the number of the water outlet holes 211 on the baffle assembly 2 is one, and the number of the water spray holes 11 on the bottom plate 1 is two, and the two water spray holes 11 are arranged at intervals in the vertical direction. When the baffle assembly 2 moves to the uppermost position, the water outlet hole 211 on the baffle 21 is completely connected with the upper water spray hole 11, that is, the upper water spray hole 11 is not blocked by the baffle assembly 2, and the lower water spray hole 11 is in a state of not being blocked by the baffle assembly 2. At this time, the flow rate of the water spray nozzle is the largest. The adjustment component 3 adjusts the baffle assembly 2 to move downward. At this time, the grouting of the lower water spray hole 11 is gradually blocked when the baffle assembly 2 moves downward. At the same time, when the upper water spray hole 11 moves downward, the connection area between the upper water spray hole 11 and the water outlet hole 211 is gradually reduced, until the water spray hole 11 on the bottom plate 1 is completely blocked by the baffle assembly 2, thereby realizing stepless adjustment of the water outlet size of the spray nozzle 100, and then adjusting the water spraying amount of the spray nozzle 100.

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

[0049] The water jet nozzle 100 of the embodiment of the present invention adjusts the relative position of the baffle assembly 2 and the bottom plate 1 in the vertical direction by setting the adjustment assembly 3, adjusts the size of the communicating area between the water jet hole 11 and the water outlet hole 211 or the size of the area blocked by the baffle assembly 2 of the water jet hole 11, that is, adjusts the size of the water outlet of the water jet nozzle 100, and adjusts the flow rate of different metal liquid columns to obtain most of the metal particles with a particle size range of 3 to 50 mm. Furthermore, the shapes of the water jet hole 11 and the water outlet hole 211 are the same to improve the stability of the stepless adjustment of the water volume.

[0050] In some embodiments, the baffle assembly 2 includes a baffle 21 and a guide groove plate 22. The end surface of the baffle 21 facing the bottom plate 1 is in contact with the bottom plate 1. Both sides of the baffle 21 are provided with guide groove plates 22 connected to the bottom plate 1. The guide groove plates 22 are provided with guide grooves 221 extending along the height direction of the bottom plate 1 toward the baffle 21. Both sides of the baffle 21 in the extension direction of the bottom plate 1 extend into the guide grooves 221 respectively.

[0051] The adjustment assembly 3 is connected to the baffle 21 so that the baffle 21 can move in the height direction of the bottom plate 1. The front end surface of the baffle 21 is in contact with the rear end surface of the bottom plate 1.

[0052] Specifically, Figures 1 to 8 As shown, the rear end of the bottom plate 1 is connected to the guide groove plate 22, and the number of the guide groove plates 22 is two, and the two guide groove plates 22 are arranged relatively spaced apart in the left and right directions. The left end of the baffle 21 extends into the guide groove 221 of the left guide groove plate 22, and the right end of the baffle 21 extends into the guide groove 221 of the right guide groove plate 22. The baffle 21 is connected to the adjustment component 3, and the adjustment component 3 drives the baffle 21 to move in the up and down direction, and the guide groove 221 is suitable for limiting 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 groove plate 22, and the right end of the baffle 21 matches the inner wall surface of the guide groove 221 of the right guide groove plate 22, so that 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 directly spraying water.

[0053] Alternatively, the guide groove 221 extends in the up-down direction, the left end of the baffle 21 contacts the guide groove 221 of the left guide groove plate 22, and the right end of the baffle 21 contacts the inner wall surface of the guide groove 221 of the right guide groove plate 22 to avoid excessive movement of the baffle 21 in the left-right direction.

[0054] The water outlet hole 211 is arranged on the baffle plate 21. For example, the number of the water outlet hole 211 on the baffle plate 21 is one, and the number of the water spray holes 11 on the bottom plate 1 is two. The two water spray holes 11 are arranged at intervals in the up and down directions. When the baffle plate 21 moves to the uppermost position, the water outlet hole 211 on the baffle plate 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 plate 21, and the water spray hole 11 below is in a state of not being blocked by the baffle plate 21. At this time, the flow rate of the water jet nozzle is the largest. The adjusting component 3 adjusts the baffle 21 to move downward. At this time, the grouting of the lower water hole 11 is gradually blocked when the baffle 21 moves downward. At the same time, when the upper water hole 11 moves downward, the connection area between the upper water hole 11 and the water outlet 211 is gradually reduced, until the water hole 11 on the bottom plate 1 is completely blocked by the baffle 21, thereby realizing stepless adjustment of the water outlet size of the jet water nozzle 100, and then adjusting the water spray volume of the jet water nozzle 100.

[0055] The water jet nozzle 100 of the embodiment of the present invention is provided with a guide groove plate 22 and a baffle plate 21. When the baffle plate 21 moves up and down, the baffle plate 21 is limited in the left and right directions to prevent the baffle plate 21 from being separated from the bottom plate 1 in the front and rear directions due to water pressure, and the baffle plate 21 is limited in the left and right directions to prevent the baffle plate 21 from being separated from the bottom plate 1 and from moving left and right, thereby improving the stability and safety of the baffle plate 21 in the up and down directions.

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

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

[0058] Alternatively, reinforced water guide plates 4 are provided on both sides of the bottom plate 1 in the height direction, and one of the reinforced water guide plates 4 is arranged above the water outlet hole 211 , and the other reinforced water guide plate 4 is arranged below the water outlet hole 211 .

[0059] It can be understood that the top and bottom of the rear end face of the baffle 21 are provided with a reinforced water guide plate 4, and the reinforced 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 reinforced water guide plate 4 is arranged above the topmost water outlet hole 211, and when the number of water outlet holes 211 is one, the reinforced water guide plate 4 is arranged above the water outlet hole 211, so as to increase the rigidity of the baffle 21 in the left and right directions, and prevent the water pressure from squeezing and deforming the baffle 21 and affecting the sealing performance. At the same time, the water flowing out of the water outlet hole 211 is guided to prevent the water flowing out of the book hole from spraying upward to impact the breaking rod, and to prevent the water from flowing to the breaking rod and causing the stability of the breaking rod.

[0060] Or, the top and bottom of the rear end surface of the baffle 21 are both provided with a reinforced water guide plate 4, and one reinforced water guide plate 4 is arranged above the water outlet 211. Alternatively, it can be understood that when there are multiple water outlets 211, one reinforced water guide plate 4 is arranged above the topmost water outlet 211, and another reinforced water guide plate 4 is arranged below the bottommost water outlet 211. When there is only one water outlet 211, the first reinforced water guide plate 4 is arranged above and below the water outlet 211. Then, the water flowing out of the water outlet 211 is guided. When the reinforced water guide plates 4 are provided in the upper and lower directions of the baffle 21, the reinforced water guide plates 4 guide the water flowing out of the water outlet 211 to prevent the water flowing out of the water outlet 211 from impacting the shattering rod upwards, and to prevent too much water from directly flowing downwards into the granulation pool 400 below, so that as much water as possible impacts the metal particles impacted by the shattering rod, thereby improving the efficiency and stability of metal granulation. At the same time, the reinforcing water guide plate 4 is arranged on the baffle plate 21 to improve the structural strength of the baffle plate 21 .

[0061] That is, when there is only one water outlet hole on the baffle 21, reinforced water guide plates 4 are provided in the upper and lower directions of the water outlet hole 211 to guide the water flowing out of the water outlet hole 211, so as to avoid the water guided by the water outlet hole 211 from losing too much kinetic energy, resulting in more water directly flowing into the granulation pool 400, thereby improving the granulation efficiency.

[0062] In some embodiments, the adjustment assembly 3 includes an adjustment rod 31, an adjustment seat 32 and a limit member 33. A ring groove 212 is provided on the side of the baffle 21 away from the base plate 1. The adjustment seat 32 is connected to the base plate 1. The adjustment rod 31 is threadedly connected to the adjustment seat 32. The adjustment rod 31 passes through the adjustment seat 32 and extends into the ring groove 212 to be connected to the limit member 33.

[0063] Specifically, Figures 1 to 8 As shown, the rear end face of the baffle 21 is provided with an annular groove 212, the adjustment seat 32 is arranged at the upper end of the bottom plate 1, the adjustment rod 31 is threadedly connected with the adjustment seat 32, the adjustment rod 31 passes through the adjustment seat 32 and extends into the annular groove 212, and the part of the adjustment rod 31 in the annular groove 212 is sleeved with a stopper 33. When the baffle 21 needs to move in the up-down direction, the adjustment rod 31 can be rotated to make the adjustment rod 31 move in the up-down direction relative to the adjustment seat 32. For example, when the adjustment rod 31 moves up-down, the stopper 33 contacts the inner wall surface of the annular groove 212. At this time, the adjustment rod 31 drives the baffle 21 to move up-down through the stopper 33. Furthermore, the outer peripheral surface where the stopper 33 contacts the inner wall surface of the annular groove 212 can be coated with lubricating oil. The friction when the adjustment rod 31 drives the stopper 33 to move is reduced.

[0064] The water jet nozzle 100 of the embodiment of the present invention can improve the adjustment accuracy of the baffle 21 in the up and down direction through the threaded cooperation between the adjusting rod 31 and the adjusting seat 32, and the baffle 21 can be moved in the up and down direction by rotating the adjusting rod 31, thereby improving the convenience of adjusting the position of the baffle 21 in the up and down direction.

[0065] Furthermore, the limiting member 33 includes a set screw and a clamping ring sleeved on the adjusting rod 31, and the set screw passes through the clamping ring and is connected to a portion of the adjusting rod 31 in the annular groove 212 by threads to fix the clamping ring, thereby improving the stability of the limiting member 33 when in use.

[0066] Furthermore, the clamping ring and the adjusting rod 31 are threadedly connected to provide an axial force, and the set screw prevents the clamping ring and the adjusting rod 31 from rotating relative to each other, thereby connecting and fixing the two together.

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

[0068] Furthermore, the adjustment assembly 3 further includes a first locking member 34, which is threadedly connected to the adjustment rod 31, and is disposed at one end of the adjustment rod 31 away from the adjustment seat 32 and the baffle 21. The first locking member 34 may be a locking nut, and after the baffle 21 moves up and down, the lower end of the first locking member 34 contacts the adjustment seat 32 and is pre-tightened to limit the adjustment rod 31.

[0069] In some embodiments, the water jet nozzle 100 also includes a water retaining bar 5, which is arranged on the top of the baffle 21 and the guide groove plate 22, or the water retaining bar 5 is arranged on the top of the baffle 21, and the two ends of the water retaining bar 5 in the extension direction of the bottom plate 1 are respectively arranged in the guide groove 221 of the guide groove plate 22 on both sides of the bottom plate 1.

[0070] Specifically, Figures 1 to 8 As shown, the water retaining bar 5 is arranged above the baffle 21. The water retaining bar 5 can be arranged on the top of the baffle 21 and the guide groove plate 22 to prevent the water between the baffle 21 and the bottom plate 1 from rushing out through the gap between the two and affecting the upper components, such as the chute 300. At the same time, the water retaining bar 5 can guide the water flow to the area below the water retaining bar.

[0071] Alternatively, the water retaining bar 5 is arranged above the baffle plate 21, and the left and right ends of the water retaining bar 5 are respectively arranged in the guide groove 221 of the guide groove plates 22 on both sides to support and limit the water retaining bar 5 to prevent the water guide bar from detaching from the bottom plate 1 or moving up and down during use. The water retaining bar guides the water between the baffle plate 21 and the bottom plate 1.

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

[0073] At the same time, a water retaining strip 5 is arranged between the two guide grooves 221 at the top of the guide groove 221 to form an inverted U-shaped water retaining structure with the guide groove 221 to prevent high-pressure water from spraying upward or to the left and right sides from the gap between the faucet bottom plate 1 and the baffle 21, thereby allowing the guided water to fall into the granulation area as much as possible.

[0074] Furthermore, the adjustment seat 32 can also have a certain guiding and limiting effect on the water guided by the water retaining bar 5, so as to prevent the water flowing upward beyond a preset range from impacting and breaking up the rod.

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

[0076] Specifically, Figures 1 to 8 As shown, the size of A can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm. At this time, when A is 10mm, the connection area between the water retaining strip 5 and the bottom plate 1 is the largest, and the connection stability of the water retaining strip 5 on the bottom plate 1 is the best.

[0077] When A is 3 mm, the connection area between the water retaining strip 5 and the bottom plate 1 is the smallest, and the connection stability of the water retaining strip 5 on the bottom plate 1 is poor.

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

[0079] In some embodiments, the water jet nozzle 100 further includes a limiting water guide plate 6 extending in the height direction of the bottom plate 1, and the limiting water guide plates 6 are provided on both sides of the baffle 21 in the extension direction of the bottom plate 1, and the limiting water guide plates 6 on both sides cooperate with the guide groove plates 22 on both sides respectively to limit the movement of the baffle 21 in the extension direction of the bottom plate 1. The limiting water guide plate 6 extends in the up and down direction. For example, the limiting water guide plate 6 contacts the guide groove plates 22 on both sides respectively to prevent the baffle 21 from moving left and right beyond a 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 21 deviates left and right, the limiting water guide plate 6 may contact the guide groove plate 22, thereby playing a role in limiting the excessive left and right deviation of the baffle 21.

[0080] Specifically, Figures 1 to 8 As shown, there are two limiting water guide plates 6, which are arranged relatively spaced apart in the left and right directions of the baffle 21. The limiting water guide plates 6 on both sides are matched with the guide groove plates 22 on the left and right sides respectively. For example, the limiting water guide plate 6 on the left side is matched with the right end of the guide groove plate 22 on the left side, and the limiting water guide plate 6 on the right side is matched with the left end of the guide groove plate 22 on the right side, thereby limiting and guiding the left and right movement of the baffle 21.

[0081] At the same time, the position of the limited water guide plate 6 on the baffle plate 21 is located on the left and right sides of the water outlet 211. The limited water guide plate 6 has a certain thickness in the front-to-back direction, and then when the water outlet 211 is discharged, the water outlet 211 is guided in the left-right direction. The main purpose of the limited water guide plate 6 and the reinforced water guide plate 4 is to increase the rigidity of the baffle plate 211 to avoid plate deformation, and at the same time, to make the water impact the metal particles in the area below the breaking rod as much as possible, that is, the water impacts the breaking area as much as possible, to improve the granulation effect and stability. At the same time, the rigidity of the baffle plate 21 in the up-down direction is enhanced to avoid deformation and enhance sealing.

[0082] In some embodiments, the water jet nozzle 100 further includes a locking assembly 7, and the guide groove plates 22 on both sides of the extending direction of the baffle plate 21 are provided with a locking assembly 7, or at least one guide groove plate 22 is provided with a locking assembly 7.

[0083] The locking assembly 7 includes a locking member 71 and a second locking member 72. The locking member 71 passes through the guide groove plate 22 and is connected to the baffle plate 21, and the locking member 71 is threadedly connected to the guide groove plate 22. The second locking member 72 is threadedly connected to the locking member 71, and the second locking member 72 is arranged at one end of the locking member 71 away from the guide groove plate 22 and the baffle plate 21.

[0084] Specifically, Figures 1 to 8As shown, the locking member 71 is threadedly connected to the guide slot plate 22, and the locking member 71 passes through the guide slot plate 22 and contacts the rear end surface of the baffle plate 21, and then the locking member 71 presses the baffle plate 21 in the front-to-back direction to prevent 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-to-back direction. The second locking member 72 is threadedly connected to the locking member 71, and when locked, the front end surface of the second locking member 72 contacts the rear end surface of the guide slot 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 locking nut.

[0085] At least one locking assembly 7 is disposed on each of the left and right guide slot plates 22, or at least one locking assembly 7 is disposed on at least one guide slot plate 22, so that the arrangement of the locking assemblies 7 can be increased or decreased according to actual conditions.

[0086] Furthermore, there are multiple adjustment components 3, and multiple annular grooves 212 are provided on the baffle 21, and multiple adjustment components 3 correspond to the annular grooves 212 of the baffle 21 one by one, thereby improving the stability and safety of the adjustment components 3 in adjusting the movement of the baffle 21.

[0087] After the jet nozzle 100 of the embodiment of the present invention is installed in place, the height of the nozzle is adjusted according to the liquid level of the pool, and the support seat 10 is welded and installed. When the granulation work starts, the second locking piece 72 of the locking assembly 7 is loosened, and then the locking piece 71 is loosened; then the first locking piece 34 of the adjustment assembly 3 is loosened, and the height of the baffle 21 in the up and down direction can be adjusted by the adjustment rod 31 of the adjustment assembly 3, thereby adjusting the water spraying amount of the jet nozzle 100. After the adjustment is completed, the first locking piece 34 of the adjustment assembly 3 is tightened, and then the locking piece 71 of the locking assembly 7 is tightened, and then the second locking piece 72 is tightened, so that the baffle 21 and the bottom plate 1 of the nozzle are closely fitted, and the amount of water leaking from the fitting surface of the two is reduced. At the same time, during the adjustment process, part of the high-pressure water will be ejected from the fitting surface of the baffle 21 and the bottom plate 1 of the nozzle. Since the guide groove 221 and the water retaining bar 5 form an inverted U-shaped water retaining structure, water is effectively prevented from being ejected from both sides or the upper side of the nozzle.
