Description

Technical Field

[0001] This utility model relates to the field of chemical nozzle technology, specifically a rotary detachable water injection nozzle. Background Technology

[0002] Oil refining generally refers to petroleum refining, which involves separating petroleum into fuel oils such as kerosene, gasoline, and diesel oil that are suitable for internal combustion engines through distillation. Byproducts include petroleum gas and residual oil. Components heavier than fuel oil are then chemically converted into fuel oil through processes such as thermal cracking and catalytic cracking. Some of these fuel oils require further refining processes such as hydrogenation. To ensure the efficiency of the oil refining process, nozzles are typically used for injection.

[0003] The related technology (publication number: CN205731697U) discloses a nozzle for chemical equipment. The disclosed technical solution is as follows: by setting a T-groove on the nozzle, the through hole connecting the inside of the nozzle is set in the T-groove. During the process of moving the sealing strip, the sealing strip covers different through holes, so that the number of through holes for outputting chemical raw materials can be adjusted. When blockage occurs outside the nozzle, the sealing strip can be moved to push the blockage away from the outside of the through hole in the T-groove, thus avoiding blockage outside the nozzle.

[0004] The above-disclosed technical solutions reveal the following problems: during the nozzle injection process, the liquid is sprayed directly in one direction, making it impossible to spray the liquid evenly within the area, thus affecting the mixing effect of the oil refining process. To address this, we propose a rotary detachable water injection nozzle.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of chemical nozzle spraying in the prior art, this utility model provides a rotary, detachable water injection nozzle that combines a rotary spraying structure with a filtration structure to improve spraying efficiency. The specific technical solution is as follows:

[0007] A rotary detachable water injection nozzle includes a nozzle, a spray chamber at the top of the nozzle, a rotating shaft rotatably mounted inside the nozzle, an injection element fixedly connected to the top of the rotating shaft within the spray chamber, a turbine chamber within the nozzle, eccentric vortex holes symmetrically formed on the outer wall of the turbine chamber, a rotation drive element fitted onto the outside of the rotating shaft within the turbine chamber, a filter chamber at the bottom of the nozzle, a filter cartridge within the filter chamber, and a disassembly / removal mechanism for replacing the filter cartridge on the filter chamber.

[0008] In the above technical solution, an annular support is embedded in the inner wall of the nozzle, and a T-shaped guide groove is circumferentially formed on the inner wall of the annular support. An annular guide seat that is slidably disposed in the inner cavity of the T-shaped guide groove is sleeved on the outer wall of the rotating shaft.

[0009] A flow stabilizing baffle is embedded in the top of the turbine chamber.

[0010] The disassembly and assembly components include an annular base fixedly installed on the top of the filter chamber. A stepped locking platform is slidably provided on the bottom of the annular base in a uniform circumferential direction. Anti-disengagement limiting seats opposite to the stepped locking platforms are fixedly installed at the bottom edge of the annular base, and an elastic element is provided between the anti-disengagement limiting seats and the stepped locking platforms.

[0011] The bottom of the annular base is uniformly provided with guide grooves, and the top of the stepped card platform is fixedly installed with a guide slider, which is slidably disposed in the inner cavity of the guide groove.

[0012] The top of the spraying component is symmetrically and rotatably provided with a spray guide plate, and the top of the spraying component is provided with a spray deflection assembly for adjusting the angle of the spray guide plate.

[0013] The jet deflection assembly includes a support column fixedly installed on the top of the jetting component, two jetting guide plates symmetrically rotated on the top of the support column, an adjustment drive seat sleeved on the outside of the support column, one end of a transmission rod being driven on the top of the adjustment drive seat, the other end of the transmission rod being rotatably disposed on the bottom of the jetting guide plate, and a displacement component for moving the position of the adjustment drive seat being provided on the top of the jetting component.

[0014] The displacement component includes a lead screw rotatably mounted on top of the injection component, and the adjustment drive seat is threaded to the outside of the lead screw.

[0015] The outer wall of the spraying component is uniformly provided with spray water channels of varying sizes.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the rotary detachable water injection nozzle:

[0017] 1. After filtration, the liquid enters the inner cavity of the turbine chamber through the eccentric vortex holes on both sides. The liquid flowing through the eccentric vortex holes forms a rotating vortex. The vortex liquid drives the rotating drive component to rotate, which in turn drives the spray component to rotate. Through the spray water grooves on the circumferential outer wall of the spray component, the liquid is evenly sprayed in the corresponding area, thereby ensuring the efficiency of the oil refining process and improving the mixing effect.

[0018] Second, when the liquid is introduced into the nozzle, it first enters the filter chamber and is filtered by the filter cartridge to remove impurities. By filtering the liquid, the quality of oil refining is ensured.

[0019] Third, as the rotating shaft drives the jet component to rotate with the vortex, the rotating shaft drives the annular guide seat to slide against the inner wall of the T-shaped guide groove through the connecting rod. The sliding cooperation between the annular guide seat and the T-shaped guide groove ensures the stability of the rotating shaft during rotation, thereby ensuring the stability of the liquid jetting process.

[0020] 4. When disassembling and assembling the filter cartridge, move the stepped mounting plates outwards respectively, and then attach the filter cartridge to the bottom of the annular base. The elastic force of the elastic element will cause the stepped mounting plates to engage with the outer wall of the filter cartridge, making the disassembly and assembly process of the filter cartridge more convenient.

[0021] Fifth, by using the jet direction-changing assembly to make the two jet guide plates rotate relative to each other, the jetting direction of the liquid is adjusted by the jet guide plates. Adjusting the direction according to the direction of liquid jetting ensures the accuracy of liquid jetting direction, thereby improving the efficiency of liquid jetting.

[0022] 6. By using a displacement component, the adjusting drive seat slides on the outer wall of the support column, causing the adjusting drive seat to move one end of the hinged transmission rod, which in turn causes the other end of the transmission rod to rotate the hinged spray guide plate, thereby adjusting the direction of liquid spraying, ensuring the accuracy of the liquid spraying direction, and improving the efficiency of the processing.

[0023] 7. The outer wall of the spraying component is uniformly provided with spraying water grooves of varying sizes, which makes the sprayed liquid range more uniform and thus improves the liquid spraying effect. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The following are specific implementation cases and appendices. Figure 1-7 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0034] A rotary, detachable water injection nozzle includes a nozzle 1, a spray chamber 2 at the top of the nozzle 1, and a rotating shaft 6 rotatably mounted inside the nozzle 1. The spray chamber 2 is fixedly mounted on the top of the nozzle 1, creating a sealed connection between the spray chamber 2 and the nozzle 1. The rotating shaft 6 rotates within the nozzle 1. A reduction gearbox 10, connected to the rotating shaft 6, is located within the nozzle 1. Multiple transmission gears within the reduction gearbox 10 increase the torque of the rotating shaft 6, thereby ensuring the rotational speed of the rotating shaft 6.

[0035] A jetting element 4, embedded in the inner cavity of the jetting chamber 2, is fixedly connected to the top of the rotating shaft 6. The top of the rotating shaft 6 is vertically fixed to the bottom of the jetting element 4, and the circumferential jetting groove of the jetting element 4 forms a jetting channel with the inner wall of the jetting chamber 2. A turbine chamber 7 is embedded in the inner cavity of the nozzle 1. The turbine chamber 7 is fixedly embedded in the inner cavity of the nozzle 1. Eccentric vortex holes 8 are symmetrically opened on the outer wall of the turbine chamber 7. Eccentric vortex holes 8 are opened on both sides of the circumferential outer wall of the turbine chamber 7 at positions off-center, so that the liquid flowing through the eccentric vortex holes 8 on both sides forms a rotating vortex, thereby making the liquid entering the inner cavity of the turbine chamber 7 vortex-shaped.

[0036] A rotary drive component 9, which is a turbine blade, is embedded in the inner cavity of the turbine chamber 7 and sleeved on the outside of the rotating shaft 6. The rotary drive component 9 is fixedly sleeved on the outside of the rotating shaft 6 through mounting holes opened in the base plate. The rotary drive component 9 is located in the inner cavity of the turbine chamber 7 and is positioned opposite to the eccentric vortex hole 8. The liquid entering the turbine chamber 7 through the eccentric vortex hole 8 drives the rotary drive component 9 to rotate, which in turn drives the rotating shaft 6 to rotate.

[0037] A filter chamber 3 is located at the bottom of the nozzle 1, and a filter cartridge 11 is installed inside the filter chamber 3. The filter chamber 3 also has a disassembly and assembly component for replacing the filter cartridge 11. The filter chamber 3 is fixedly installed at the bottom of the nozzle 1, ensuring a sealed connection between the filter chamber 3 and the inner cavity of the nozzle 1. A threaded connector is fixedly installed at the bottom of the filter chamber 3, making nozzle installation easier. The threaded connector secures the filter chamber 3 to the corresponding pipe.

[0038] When the liquid is introduced into the nozzle 1, it first enters the inner cavity of the filter chamber 3, where it is filtered by the filter cartridge 11 to remove impurities. This filtration process ensures the quality of the oil refining process. The filtered liquid then enters the inner cavity of the turbine chamber 7 through the eccentric vortex holes 8 on both sides. The flowing liquid forms a rotating vortex through the eccentric vortex holes 8, which drives the rotating drive component 9 to rotate, thereby rotating the rotating shaft 6. The rotating shaft 6 then drives the spray component 4 to rotate, and the liquid is evenly sprayed into the corresponding area through the spray channels on the outer wall of the spray component 4, thus ensuring the efficiency of the oil refining process and improving the mixing effect.

[0039] The nozzle 1 has an annular support 13 embedded in its inner wall. A T-shaped guide groove 25 is circumferentially formed on the inner wall of the annular support 13. An annular guide seat 14, slidably disposed within the cavity of the T-shaped guide groove 25, is fitted onto the outer wall of the rotating shaft 6. One end of a connecting rod 15 is circumferentially and evenly fixedly installed on the inner wall of the annular guide seat 14. The other end of the connecting rod 15 is sequentially and circumferentially fixedly installed on the outer wall of the sleeve 27. The sleeve 27 is fixedly fitted onto the outer wall of the rotating shaft 6 through a longitudinally formed through-hole penetrating the inner cavity. A T-shaped guide groove 25 with a T-shaped cross-section is formed on the inner wall of the annular guide seat 14.

[0040] As the rotating shaft 6 rotates with the vortex, the rotating shaft 6 drives the annular guide seat 14 to slide against the inner wall of the T-shaped guide groove 25 through the connecting rod 15. The sliding cooperation between the annular guide seat 14 and the T-shaped guide groove 25 ensures the stability of the rotating shaft 6 during rotation, thereby ensuring the stability of the liquid jetting process.

[0041] A flow stabilizing baffle 12 is embedded in the top of the turbine chamber 7. The flow stabilizing baffle 12 is fixedly installed on the top of the turbine chamber 7, so that the liquid forming a vortex in the inner cavity of the turbine chamber 7 enters the interior of the injection chamber 2 through the through hole on the flow stabilizing baffle 12, thus ensuring the stability of the liquid injection process.

[0042] It is worth noting that the disassembly and assembly components include an annular base 19 fixedly installed on the top of the filter chamber 3. The annular base 19 is sleeved on the outer wall of the nozzle 1 by a fastener, which allows the filter chamber 3 to be disassembled. The through hole in the center of the annular base 19 is aligned with the inner cavity of the nozzle 1. A stepped retaining platform 24 is slidably provided evenly around the bottom of the annular base 19. Anti-disengagement limiting seats 26 are fixedly installed at the bottom edge of the annular base 19, opposite to the stepped retaining platform 24, and an elastic element 23 is provided between the anti-disengagement limiting seat 26 and the stepped retaining platform 24.

[0043] The stepped locking platform 24 is stepped on the side facing the center of the annular base 19, and the stepped shape corresponds to the shape of the top outer wall of the filter cartridge 11, so that the stepped locking platform 24 can be locked onto the outside of the filter cartridge 11. The elastic element 23 is a spring sheet, one end of which is fixedly installed on the side of the anti-disengagement limiting seat 26 facing the center of the annular base 19, and the other end of which is fixedly installed on the side of the stepped locking platform 24 away from the center of the annular base 19.

[0044] When disassembling and assembling the filter cartridge 11, the stepped locking platforms 24 are moved outwards, causing them to slide against the bottom of the annular base 19, while simultaneously compressing the elastic element 23 and generating elastic force. The filter cartridge 11 is then placed against the bottom of the annular base 19, and the elastic force of the elastic element 23 causes the stepped locking platforms 24 to engage with the outer wall of the filter cartridge 11, thus making the disassembly and assembly process of the filter cartridge 11 more convenient.

[0045] The bottom of the annular base 19 is evenly provided with guide grooves 22. The top of the stepped mounting platform 24 is fixedly installed with a guide slider 21, which is slidably disposed in the inner cavity of the guide groove 22. The outermost side of the guide groove 22 is blocked by an anti-detachment limiting seat 26 to prevent the stepped mounting platform 24 from detaching from the annular base 19, thereby ensuring the stability of the filter cartridge 11 after installation.

[0046] In addition, a spray guide plate 5 is symmetrically rotated on the top of the spray component 4, and a spray deflection assembly for adjusting the angle of the spray guide plate 5 is provided on the top of the spray component 4.

[0047] The jet direction changer assembly causes the two jet guide plates 5 to rotate relative to each other, so that the liquid jetted by the jetting component 4 can be adjusted by the jet guide plates 5 to adjust the jetting direction. The adjustment is made according to the direction of liquid jetting, which ensures the accuracy of liquid jetting direction and thus improves the efficiency of liquid jetting.

[0048] Additionally, the jet deflection assembly includes a support column 16 fixedly mounted on top of the jetting component 4, with two jetting guide plates 5 symmetrically rotatably mounted on top of the support column 16. A portion of a hinge is mounted on top of the support column 16, and the other portion of the hinge is fixed to the bottom of each of the two jetting guide plates 5, allowing the two jetting guide plates 5 to rotate relative to each other. An adjustment drive seat 17 is sleeved on the outside of the support column 16, and one end of a transmission rod 20 is driven onto the top of the adjustment drive seat 17. The other end of the transmission rod 20 is rotatably mounted on the bottom of the jetting guide plates 5.

[0049] Brackets are installed at the bottom of the two spray guide plates 5 and at the top of the adjusting drive seat 17. Each bracket has a mounting shaft embedded in it. The two ends of the transmission rod 20 are movably sleeved onto the outside of the rotating shafts of the brackets on the adjusting drive seat 17 and the spray guide plates 5 through mounting holes in the connectors. This allows the two ends of the transmission rod 20 to be hinged to the spray guide plates 5 and the adjusting drive seat 17. The adjusting drive seat 17 is movably sleeved onto the outside of the support column 16 through a mounting hole in its center, allowing the adjusting drive seat 17 to slide against the outer wall of the support column 16.

[0050] The top of the spraying component 4 is provided with a displacement component that moves the adjustment drive seat 17. The displacement component causes the adjustment drive seat 17 to slide on the outer wall of the support column 16, which in turn causes one end of the hinged transmission rod 20 to move, and the other end of the transmission rod 20 to rotate the hinged spray guide plate 5, thereby adjusting the direction of liquid spraying, ensuring the accuracy of the liquid spraying direction and improving the efficiency of the processing.

[0051] Furthermore, the displacement component includes a lead screw 18 rotatably mounted on top of the spraying component 4, with an adjusting drive seat 17 threadedly connected to the outside of the lead screw 18. A mounting bracket is fixedly installed on top of the spraying component 4, located on one side of the support column 16, allowing the lead screw 18 to rotate on the mounting bracket and be in a position parallel to the support column 16. A motor is fixed to the top of the mounting bracket via a cover, with the motor's output shaft passing through the mounting bracket and fixedly connected to the end corresponding to the lead screw 18. The motor is electrically connected to an external power source via wires.

[0052] When adjusting the angle of the two spray guide plates 5, the motor drives the lead screw 18 to rotate, which causes the threaded adjustment drive seat 17 to drive the spray guide plate 5 to rotate through the hinged transmission rod 20, making the operation of the liquid spray direction more convenient.

[0053] The outer wall of the spray component 4 is uniformly provided with spray water grooves of varying sizes, which makes the sprayed liquid range more uniform and thus improves the liquid spraying effect.

[0054] This embodiment describes a rotary, detachable water injection nozzle. Its working principle is as follows: First, the filter chamber 3 is fixed to the corresponding pipe via a threaded connection seat. When injection liquid is introduced into the nozzle 1, the liquid enters the inner cavity of the filter chamber 3 and is filtered by the filter cartridge 11 to remove impurities.

[0055] After filtration, the liquid enters the inner cavity of the turbine chamber 7 through the eccentric vortex holes 8 on both sides. The liquid flowing through the eccentric vortex holes 8 forms a rotating vortex, which drives the rotating drive component 9 to rotate. This rotating drive component 9 drives the rotating shaft 6 to rotate, which in turn drives the spray component 4 to rotate. The spray component 4 sprays water into the water channels on its outer wall, ensuring that the liquid is evenly sprayed in the corresponding area.
