Description

Technical Field:

[0001] The present invention belongs to the technical field of agitators for oil storage tanks, and particularly relates to an adjustable-angle rotary jet agitator for solving the problem of low-level impact on floating roofs. Background Art:

[0002] An oil storage tank is a canned device for storing oil products, and it is also one of the main storage and transportation containers for oil products at present. When oil products are stored statically for a long time, problems such as stratification and sedimentation will occur, which will seriously affect the quality of oil products and also affect the use of oil products.

[0003] To ensure that sedimentation and other problems do not occur during the storage of oil products, it is necessary to stir the oil products. However, traditional stirring rods are not suitable for use in oil products, and the oil products will also adhere to the stirring rods. Therefore, rotary jet agitators are basically used to stir the oil products now.

[0004] A floating roof refers to an environmental protection structure that floats on the liquid and rises and falls synchronously with the liquid level. There are floating roofs in many storage tanks, and oil storage tanks are no exception. As the oil products are discharged, the floating roof will lower. When the liquid level is low, the floating roof may be impacted by the rotary jet agitator, which will affect the service life of the floating roof and also cause the floating roof to collide frequently with the inner wall of the storage tank, affecting the storage tank. Therefore, an adjustable-angle rotary jet agitator for solving the problem of low-level impact on the floating roof is proposed here. Summary of the Invention:

[0005] The purpose of the present invention is to provide an adjustable-angle rotary jet agitator for solving the problem of low-level impact on the floating roof, which can avoid causing a large impact on the floating roof at low liquid levels, thereby damaging the floating roof and the storage tank.

[0006] To solve the above problems, the present invention provides an adjustable-angle rotary jet agitator for solving the problem of low-level impact on the floating roof, including a main body. Four pairs of connecting plates are evenly and fixedly connected to the outer wall of the main body. A spray head is rotatably connected between each pair of connecting plates. An inner groove is formed inside the connecting plate. A positioning wheel is rotatably connected inside the inner groove. Two limiting plates are fixedly connected to the inner wall of the inner groove, and the positions of the two limiting plates correspond to 45° and 135° of the positioning wheel. Corresponding slots are formed on both side walls of the positioning wheel. A driven gear is fixedly connected to one side wall of the positioning wheel. A main gear is rotatably connected to one side wall of the connecting plate. The main gear is meshed with the driven gear. A docking column is fixedly connected to the middle of one side wall of the main gear, and one end of the docking column is detachably connected to both side walls of the spray head.

[0007] Preferably, the limiting plate is of a concave-shaped structure. The positioning wheel rotates through the middle of the limiting plate. In the middle of the outer walls on both sides of the limiting plate, side boxes are fixedly connected. An electromagnet is embedded in one side wall of each side box. Through holes are formed through both side walls of the limiting plate, and inserting columns are telescopically inserted into the through holes.

[0008] Preferably, since the limiting plate is of a concave-shaped structure, it can be sleeved on the positioning wheel without affecting the rotation of the positioning wheel. While ensuring the rotation of the positioning wheel, it is convenient to limit and position the positioning wheel, thereby adjusting the orientation of the fixed nozzle.

[0009] Preferably, the position of the inserting column corresponds to that of the inserting slot. One end of the inserting column is of a semi-circular structure and is inserted into the inserting slot. Fixed blocks are fixedly connected to the outer circumferential walls on both sides of the end of the inserting column located inside the side box. A top support spring is fixedly connected to one side wall of each fixed block. The top support spring is fixedly connected to the inner wall of the side box through its end far from the fixed block. The electromagnet corresponds to the inserting column, and the inserting column is a magnetic metal rod.

[0010] Preferably, since one end of the inserting column is inserted into the inserting slot, the positioning wheel can be positioned, ensuring that the positioning wheel is fixed in a specified state, thereby limiting the nozzle and facilitating flexible adjustment of the nozzle according to needs, avoiding impact on the floating tray, and the telescopic state of the inserting column can be controlled by the electromagnet and the top support spring.

[0011] Preferably, a connecting hose is fixedly connected to one end of the nozzle close to the main body. One end of the connecting hose is fixed at the oil outlet formed through the side wall of the main body. A pressurizing port is formed inside the nozzle. The pressurizing port is of a conical structure. A blocking block is rotatably connected to the pressurizing port through a torsion spring near the outlet. A check plate is fixedly connected to the inner wall of the pressurizing port. The blocking block is of an inclined structure.

[0012] Preferably, since the pressurizing port is designed to be of a conical structure, the liquid passing through can be naturally pressurized, improving the spraying impact force and the stirring effect. At the same time, the blocking block and the check plate can prevent the outside liquid from flowing into the main body along the nozzle, and the established connecting hose can ensure the smooth rotation and adjustment of the nozzle.

[0013] Preferably, a lifting column is inserted and movably connected to the top inside the main body. The top end of the lifting column is detachably connected to a receiving plate. A conical plate is fixedly connected to the side wall of the main body located below the nozzle. An opening is formed through the middle of the bottom of the conical plate. One end of the lifting column extending into the main body is fixedly connected to a blocking plate. The blocking plate is of a conical structure corresponding to the conical plate.

[0014] Preferably, the liquid flow rate can be adjusted according to the situation through the provided blocking plate and conical plate, so as to adjust the amount of liquid ejected from the nozzle, and thus adjust the impact force generated by stirring.

[0015] Preferably, the blocking plate is inserted into the conical plate without fitting. A stress plate is fixedly connected to the outer peripheral wall of the lifting column close to the blocking plate. The top side wall of the stress plate is uniformly and fixedly connected with pressing springs, and the pressing springs are fixedly connected to the inner top side wall of the main body through the ends far away from the stress plate.

[0016] Preferably, since there is a gap between the blocking plate and the conical plate after insertion, the smoothness of liquid flow can be ensured, so as to achieve the effect of flow rate adjustment. The provided pressing springs can drive the blocking plate to sink.

[0017] Preferably, connecting columns are uniformly and fixedly connected to the bottom of the receiving plate near the edge. An activity column is telescopically and movably inserted into the connecting columns. The bottom end of the activity column is fixedly connected with a counterweight block. The receiving plate is provided with through holes. The initial position of the receiving plate is higher than the lowest liquid level by -cm.

[0018] Preferably, the provided receiving plate can support the floating disc, so that the floating disc can be separated from the liquid, thus avoiding damage caused by the impact and shaking of the floating disc against the inner wall of the storage tank.

[0019] Preferably, the bottom end of the main body is rotatably connected with a mounting seat. A motor is detachably connected to the middle of the mounting seat, and the output end of the motor is detachably connected to the middle of the bottom side wall of the main body. The mounting seat is detachably connected to the bottom side wall of the storage tank through screws. A suction port is fixedly connected to the side wall of the main body close to the mounting seat. One end of the suction port extends into the main body and is detachably connected to the bottom opening of the conical plate.

[0020] Preferably, the motor can normally drive the main body to rotate, and the liquid can be extracted and sent into the main body through the provided suction port and finally ejected from the nozzle, cooperating with the rotating main body to achieve the effect of rotary jet stirring.

[0021] The beneficial effects of the present invention: Since the orientation angle of the nozzle can be adjusted by rotating the nozzle, when the liquid level is low, the nozzle can be rotated downward, and at the same time, the slot will contact and be fixed to the limiting plate at 135°, so that the ejected liquid will not impact on the floating disc, thus avoiding some problems caused by the impact and shaking of the floating disc. When the liquid level is high, the nozzle can be rotated in reverse, and at the same time, the slot will enter and be fixed in the limiting plate at the 45° position, ensuring the smooth progress of stirring. Since the orientation angle of the nozzle can be adjusted according to needs, the flexibility and practicality of equipment application can be improved. Description of the drawings:

[0032] Example 1

[0033] As Figure 1-8As shown in the figure, the following technical solution is adopted in this specific embodiment: An adjustable-angle rotary jet mixer for solving the problem of low liquid level impact on the floating roof, including a main body 1. Four pairs of connecting plates 2 are evenly and fixedly connected to the outer wall of the main body 1. A spray head 3 is rotatably connected between each pair of connecting plates 2. An inner groove 14 is formed inside the connecting plate 2. A positioning wheel 16 is rotatably connected inside the inner groove 14. Two limiting plates 17 are fixedly connected to the inner wall of the inner groove 14. The positions of the two limiting plates 17 correspond to 45° and 135° of the positioning wheel 16. Corresponding slots 18 are formed on both side walls of the positioning wheel 16. A driven gear 15 is fixedly connected to one side wall of the positioning wheel 16. A main gear 8 is rotatably connected to one side wall of the connecting plate 2. The main gear 8 is meshed with the driven gear 15. A docking column 13 is fixedly connected to the middle of one side wall of the main gear 8. One end of the docking column 13 is detachably connected to both side walls of the spray head 3.

[0034] As the technical effect of this embodiment: Since the main gear 8 is connected to the spray head 3 through the docking column 13, the rotation of the spray head 3 can drive the rotation of the main gear 8. And because the main gear 8 is meshed with the driven gear 15, the rotation of the main gear 8 will drive the driven gear 15 to rotate synchronously, thereby driving the positioning wheel 16 fixed to the driven gear 15 to rotate. Two limiting plates 17 are provided inside the inner groove 14. By the two limiting plates 17 being at the two positions of 45° and 135° of the positioning wheel 16, when the slot 18 is rotated to these two positions, it will be fixed, thus positioning the spray head 3. In this way, the orientation angle of the spray head 3 can be adjusted, so as to avoid impacting the floating roof at low liquid level.

[0035] Embodiment Two

[0036] As Figure 1 、 3 shown in Fig. -6, the limiting plate 17 is of a concave structure. The positioning wheel 16 rotates through the middle of the limiting plate 17. Side boxes 19 are fixedly connected to the middle of the outer walls on both sides of the limiting plate 17. An electromagnet 22 is inlaid on one side wall inside the side box 19. Through holes 21 are formed through both side walls of the limiting plate 17. Plug posts 20 are telescopically inserted inside the through holes 21. The positions of the plug posts 20 correspond to the slots 18. One end of the plug post 20 is of a semi-circular structure and is inserted into the slot 18. Fixed blocks 23 are fixedly connected to the outer circumferential walls on both sides of the end of the plug post 20 located inside the side box 19. A top support spring 24 is fixedly connected to one side wall of the fixed block 23. The top support spring 24 is fixedly connected to the inner wall of the side box 19 through its end far from the fixed block 23. The electromagnet 22 corresponds to the plug post 20. The plug post 20 is a magnetic metal rod.

[0037] The technical effect of this embodiment is as follows: as the positioning wheel 16 rotates, the slot 18 will also move accordingly. When the slot 18 moves to a position relative to the plug post 20, one end of the plug post 20 can be inserted into the slot 18 through the drive of the support spring 24, thereby achieving the positioning effect of the positioning wheel 16, and different positioning positions can fix the nozzle 3 at different orientation angles, increasing the flexibility and adaptability of the adjustment, and the electromagnet 22 can be set up to pull the plug post 20 out of the slot 18 by magnetic attraction, thereby freeing the positioning wheel 16 so that it can rotate normally with the main gear 8.

[0038] Embodiment 3

[0039] like Figure 1-2 As shown, one end of the nozzle 3 close to the main body 1 is fixedly connected to a connecting hose 9, one end of the connecting hose 9 is fixed to the oil outlet opened through the side wall of the main body 1, a pressurizing port 10 is opened inside the nozzle 3, the pressurizing port 10 is a conical structure, a stopper 11 is rotatably connected inside the pressurizing port 10 and close to the outlet through a torsion spring, a check plate 12 is fixedly connected to the inner wall of the pressurizing port 10, and the stopper 11 is an inclined structure.

[0040] The technical effect of this embodiment is as follows: in order to ensure the impact force of the liquid spraying, a conical pressurizing port 10 is opened in the nozzle 3. The liquid passing through the pressurizing port 10 will be pressurized and finally break through the block 11 and spray out from the outlet of the nozzle 3. The established block 11 and the check plate 12 can effectively play a check effect. In order to ensure the smooth rotation and adjustment of the nozzle 3, a connecting hose 9 is used to connect the nozzle 3 with the main body 1.

[0041] Embodiment 4

[0042] like Figure 1 and 7 -8, a lifting column 6 is movably connected to the top of the main body 1, and a receiving plate 7 is detachably connected to the top of the lifting column 6. A conical plate 28 is fixedly connected to the inner wall of the main body 1 and the side wall below the nozzle 3. An opening is provided in the middle of the bottom of the conical plate 28. One end of the lifting column 6 extending into the main body 1 is fixedly connected to a blocking plate 27. The blocking plate 27 is a conical structure corresponding to the conical plate 28. The blocking plate 27 is inserted into the conical plate 28 and does not fit. The lifting column 6 is close to the outer wall of the blocking plate 27. A force-bearing plate 25 is fixedly connected, and a suppression spring 26 is evenly fixedly connected to the top side wall of the force-bearing plate 25. The suppression spring 26 is fixedly connected to the top side wall of the main body 1 through its end away from the force-bearing plate 25. A connecting column 29 is evenly fixedly connected to the bottom of the receiving plate 7 near the edge. A movable column 30 is telescopically inserted in the connecting column 29, and a counterweight block 31 is fixedly connected to the bottom end of the movable column 30. A mesh is opened through the receiving plate 7, and the initial position of the receiving plate 7 is 1-3 cm higher than the lowest liquid level.

[0043] The technical effect of this embodiment is as follows: when the liquid level drops below the receiving plate 7, the lifting column 6 will be pressed into the main body 1 under the pulling of the counterweight 31. With the cooperation of the pressing spring 26, the blocking plate 27 can be smoothly inserted into the conical plate 28. Since the blocking plate 27 does not fit tightly with the conical plate 28, there are gaps for liquid to flow through, but the flow rate will be adjusted to regulate the amount of liquid sprayed, thereby reducing the impact caused by the sprayed liquid. Similarly, the floating plate that drops with the liquid will be placed on the receiving plate 7 and separated from the liquid to avoid being impacted.

[0044] Embodiment Five

[0045] As Figure 1 and 7 As shown in the figure, a mounting seat 5 is rotatably connected to the bottom end of the main body 1. A motor is detachably connected in the middle of the mounting seat 5, and the output end of the motor is detachably connected to the middle of the bottom side wall of the main body 1. The mounting seat 5 is detachably connected to the bottom side wall of the storage tank by screws. A suction port 4 is fixedly connected to one side wall of the main body 1 close to the mounting seat 5. One end of the suction port 4 extends into the main body 1 and is detachably connected to the bottom opening of the conical plate 28.

[0046] The technical effect of this embodiment is as follows: starting the motor can drive the main body 1 to rotate, thereby driving the nozzle 3 to rotate. At the same time, the liquid is pumped into the main body 1 through the suction machine built in the suction port 4 and finally sprayed out from the nozzle 3 to achieve the effect of rotary spraying. The sprayed liquid will generate turbulence with the liquid in the storage tank to stir the liquid, so as to mix the liquid evenly and avoid stratification and sedimentation.

[0047] Specifically: during use, as the liquid in the storage tank is pumped out, its liquid level gradually drops. When the liquid level is too low, rotate the nozzle 3 downward so that the outlet of the nozzle 3 faces downward, thereby avoiding the impact of the sprayed liquid on the floating plate, and also preventing the problem of impact damage to the inner wall of the storage tank caused by the shaking of the floating plate. Similarly, since the lowest position of the receiving plate 7 is also higher than the lowest liquid level, the floating plate will eventually be supported above the lowest liquid level by the receiving plate 7, thus completely eliminating the problem of the floating plate being impacted. As the liquid level rises, the nozzle 3 will also rotate upward. In the low liquid level state, the blocking plate 27 will be inserted into the conical plate 28 to adjust the liquid flow rate and reduce the impact force caused by the sprayed liquid, thereby reducing the amplitude of the liquid's own shaking. Since the liquid is reduced, the reduction in impact does not affect the actual stirring effect. When the liquid level rises, everything returns to the normal operating state;

[0048] Regarding the driving method of the nozzle 3, the motor can be connected to the main gear 8 or the positioning wheel 16 for control to achieve the effect of automatic control. The specific control method is adjusted according to the actual situation and the properties of the liquid stored in the storage tank.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
