Description

Technical Field

[0001] This invention relates to the field of nozzle technology, and more particularly to a nozzle jet module and a three-dimensional rotating nozzle. Background Technology

[0002] Three-dimensional rotary nozzles are primarily used for cleaning the internal space of reaction vessels. Their principle involves using the torque generated by the reaction force of two counter-aligned nozzles spraying water to control the nozzle's rotation, simultaneously driving the entire nozzle to rotate and achieve three-dimensional rotary cleaning. When dealing with reaction vessels of different sizes and media, the rotation speed of the three-dimensional rotary nozzle is typically carefully controlled to achieve a balance between cleaning efficiency and thoroughness, resulting in optimal cleaning performance. Currently available three-dimensional rotary nozzles either use an adjustable reduction gear set internally to control the speed or a motor coupled to the nozzle's internal rotating shaft. Both of these methods require complex internal linkage structures, increasing operating costs and enhancing the nozzle's vulnerability to damage, thus shortening its lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide a nozzle jet module that has a simple structure and can be quickly adjusted.

[0004] To achieve this objective, the present invention adopts the following technical solution: a nozzle jet module, comprising a mounting base, two nozzles, and a pressure block. The mounting base is connected to a main shaft, which is coaxial with the mounting base and has a water passage. The mounting base has two diversion channels communicating with the water passage. Both nozzles are sealed to the mounting base and can rotate relative to the mounting base. The two nozzles are symmetrically arranged around the center of the main shaft and are respectively connected to the two diversion channels. The sidewalls of both nozzles are provided with bosses. The pressure block is bolted to the mounting base and is adapted to abut against the side of the two bosses opposite to the mounting base to lock the two nozzles.

[0005] Preferably, at least a portion of the sidewall of the boss is provided with a gear portion, the center of the mounting base is provided with a rotatable idler wheel, the pressure block is covered by the idler wheel, and the gear portions of both nozzles mesh with the idler wheel.

[0006] Preferably, the pressure block has two symmetrical angle scale lines on the side of its edge away from the mounting base, and each of the two nozzles has an arrow pointing to the angle scale lines on the side away from the mounting base.

[0007] Preferably, when the pressure block abuts against the boss, the side of the pressure block away from the mounting base and the side of the nozzle away from the mounting base are flush.

[0008] Preferably, the nozzle includes a rotating block and a nozzle body. The rotating block has a jet channel that communicates with the corresponding flow distribution channel. The nozzle body is detachably connected to the rotating block and communicates with the jet channel.

[0009] Preferably, one of the rotating block and the mounting base has a protrusion, and the other has a socket that engages with the protrusion. The inner circumferential wall of the socket has an annular groove, and the jet channel and the diversion channel are connected through the groove.

[0010] Preferably, a sealing assembly is provided between the protrusion and the inner wall of the insertion hole.

[0011] Preferably, the sealing assembly includes two sealing rings, which are spaced apart on both sides of the groove along the depth direction of the insertion hole.

[0012] Preferably, the extension of the centerline of the nozzle body does not intersect with the centerline of the main shaft.

[0013] Another objective of this invention is to provide a three-dimensional rotating nozzle that is simple in structure and easy to control.

[0014] To achieve this objective, the present invention adopts the following technical solution: a three-dimensional rotating nozzle, comprising a housing, a water inlet rod, and the aforementioned nozzle jet module, wherein the main shaft and the water inlet rod are connected by a bevel gear assembly and are both rotatably connected to the housing, and the water inlet rod is provided with a water inlet channel communicating with the water passage.

[0015] The beneficial effects of this invention are as follows: By setting rotatable nozzles, after the jet module is installed on the three-dimensional rotating nozzle, rotating the two nozzles can change the radial distance between the water outlet end of the nozzle and the main shaft, thereby changing the torque generated by the two nozzles under the reaction force and adjusting the rotational speed of the entire jet module. The jet module has a simple structure, is easy to adjust in speed, and does not rely on electromagnetic principles for speed adjustment, which can effectively reduce the design and use costs of the three-dimensional rotating nozzle.

[0016] The present invention also provides a three-dimensional rotating nozzle, which achieves speed adjustment by adjusting the nozzle angle, simplifies the nozzle structure, and improves the ease of use of the nozzle. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0023] Reference Figures 1 to 6 As shown, a nozzle jet module according to an embodiment of this application includes a mounting base 1, two nozzles 3, and a pressure block 4. The mounting base 1 is circular, and a main shaft 2 is connected to the center of one side of the mounting base 1. The main shaft 2 is coaxial with the mounting base 1 and has a water passage 21. The mounting base 1 has two diversion channels 11 communicating with the water passage 21. The two nozzles 3 are sealed to the mounting base 1 and can rotate relative to the mounting base 1. The two nozzles 3 are symmetrically arranged around the center of the main shaft 2 and are respectively connected to the two diversion channels 11. The sidewalls of the two nozzles 3 are provided with bosses 31, which are arc-shaped and extend radially along the rotation axis of the nozzles 3. The pressure block 4 is bolted to the side of the mounting base 1 opposite to the main shaft 2 by two screws. The pressure block 4 spans over part of the bosses 31 of the two nozzles 3 and is adapted to abut against the side of the two bosses 31 opposite to the mounting base 1 to lock the two nozzles 3. Specifically, turning the screw loosens the pressure block 4, so there is no contact between the pressure block 4 and the boss 31, and the nozzle 3 can rotate relative to the pressure block 4 and the mounting base 1. Turning the screw tightens the pressure block 4, so the pressure block 4 and the mounting base 1 cooperate to clamp the boss 31. The friction between the pressure block 4 and the mounting base 1 can restrict the rotation of the nozzle 3, thereby locking the nozzle 3.

[0024] In this embodiment, the angle between the water outlet direction of the nozzle 3 and the radial direction (from the mounting base 1 to the water outlet end of the nozzle 3) is defined as α. Since the nozzle 3 can rotate relative to the mounting base 1, α is obviously an adjustable parameter. In an ideal situation (no friction, stable water flow), the reaction force F on each nozzle 3 is in the opposite direction to the water outlet direction. The reaction force F can be decomposed into a radial component Fr and a tangential component Ft (Ft = F × sinα). The direction of Fr is the radial direction of the nozzle 3, and Fr does not generate torque on the mounting base 1. The direction of Ft is perpendicular to the radial direction, and the mounting base 1 generates a driving torque under the drive of Ft. Since the two are symmetrical and opposite, their tangential forces are in the same direction. Therefore, the total driving torque τ of the mounting base 1 is... total =2×R×F×sinα, where R is the distance from the center of the mounting base 1 to the rotation axis of the nozzle 3. Clearly, during the user's rotation of the nozzle 3, R and F remain constant, and the total driving torque τ... total It changes as the angle of nozzle 3 changes.

[0025] Understandably, by setting rotatable nozzles 3, after the jet module is installed on the three-dimensional rotating nozzle, rotating the two nozzles 3 changes the radial distance between the water outlet end of the nozzle 3 and the main shaft 2. Under the premise of constant water pressure (i.e., constant reaction force on the nozzle 3), the lever arm of the nozzle 3 changes, thereby changing the magnitude of the torque generated by the two nozzles 3 under the reaction force, and adjusting the rotational speed of the entire jet module. The jet module has a simple structure, convenient speed adjustment, and can steplessly adjust the rotational speed without relying on electromagnetic principles, which can effectively reduce the design and use cost of the three-dimensional rotating nozzle and extend its service life.

[0026] It should be noted that in some embodiments, the mounting base 1 and the main shaft 2 are detachably and sealedly connected, which facilitates the installation, removal and debugging of the jet module. In other embodiments, the mounting base 1 and the main shaft 2 are integrally formed to ensure the structural stability and sealing of the jet module.

[0027] Reference Figure 2 and Figure 3 As shown, it can be understood that at least part of the sidewall of the boss 31 is provided with a gear part 311, the center of the mounting base 1 is provided with a protruding structure, an idler wheel 12 is sleeved on the protruding structure, the pressure block 4 is covered on the idler wheel 12, and the gear parts 311 of the two nozzles 3 are engaged with the idler wheel 12.

[0028] If the two water outlets of the jet module are not strictly symmetrical (the water outlet directions are parallel and opposite) before and after rotation, but instead have a certain angle, it will disrupt the force couple balance, introduce a new torque vector, and generate an unbalanced lateral resultant force while the jet module is rotating, leading to problems such as jet module vibration, speed fluctuation, and uneven spraying. By using a gear unit 311 and an idler wheel 12 to link the two nozzles 3, the operator can rotate one nozzle 3 at will, and the other nozzle 3 will rotate synchronously in the opposite direction under the drive of the idler wheel 12. This achieves reverse linkage between the two nozzles 3, effectively improving the synchronization rate of the two nozzles 3, eliminating manual operation errors, controlling the angle error between the water outlets of the two nozzles 3 within a reasonable range, and effectively improving the rotational stability of the jet module.

[0029] Reference Figure 1As shown, it can be understood that the sidewalls of the pressure block 4 facing the two nozzles 3 are arc-shaped. Two angle scale lines 41 are symmetrically provided at the center of the edge of the pressure block 4 away from the mounting base 1. The angle scale lines 41 are arc-shaped and match the edge of the pressure block 4. Each of the two nozzles 3 has an arrow marker 32 pointing to the angle scale line 41 on the side away from the mounting base 1. In this embodiment, the angle scale line 41 ranges from 0 to 90°. When the nozzle 3 is in the position of maximum torque (i.e., when the water outlet direction of the nozzle 3 is perpendicular to the line connecting the nozzle 3's rotation axis and the water passage 21), the rotation angle of the nozzle 3 is 90°. In other embodiments, the range of the angle scale line 41 can be 0-120°, 0-130°, etc., which will not be elaborated here.

[0030] By setting the angle scale line 41 and the arrow mark 32, the operator can easily control the rotation angle of the nozzle 3 quantitatively, thereby accurately adjusting the speed of the jet module, effectively improving the controllability of the jet module and enhancing the user experience of the operator.

[0031] Furthermore, when the pressure block 4 abuts against the boss 31, the side of the pressure block 4 facing away from the mounting base 1 and the side of the nozzle 3 facing away from the mounting base 1 are flush. In other words, when the pressure plate locks the nozzle 3, the angle scale line 41 and the arrow mark 32 are in the same plane.

[0032] The pressure block 4 is arranged flush with the end face of the boss 31 to eliminate the height difference between the angle scale line 41 and the arrow mark 32, avoid the operator from misreading the rotation angle of the nozzle 3, and improve the readability of the arrow mark 32.

[0033] Reference Figure 5 As shown, the nozzle 3 includes a rotating block 33 and a nozzle body 34. The rotating block 33 has a jet channel 331 that communicates with the corresponding diversion channel 11. The rotating block 33 has a D-shaped structure with a flat side and a boss 31 on the other side. The nozzle body 34 is positioned between the flat sidewall of the rotating block 33 and the boss 31 along a direction parallel to the upper flat surface of the rotating block 33. At this time, the extension line of the centerline of the nozzle body 34 (collinear with the water outlet direction of the nozzle 3) is spaced apart from the rotating shaft of the nozzle 3. The nozzle body 34 is detachably connected to the rotating block 33 and communicates with the jet channel 331. Optionally, the nozzle body 34 can be threaded, snap-fitted, or sealed with an O-ring to the rotating block 33, which will not be elaborated here.

[0034] By setting a detachable nozzle body 34, operators can easily replace the corresponding type of nozzle body 34 according to different usage environments. For example, when facing large areas of impurities that are easy to clean, an open-type atomizing fluid nozzle body 34 can be installed. When facing small areas of impurities that are difficult to clean, a gradually narrowing pressurized jet fluid nozzle body 34 can be installed, effectively improving the practicality of the jet module.

[0035] Reference Figure 4 and Figure 5 As shown, it can be understood that one of the rotating block 33 and the mounting base 1 is provided with a cylindrical protrusion 332, and the other is provided with a socket 13 that is inserted and engaged with the protrusion 332. The inner peripheral wall of the socket 13 is provided with an annular groove 131, and the jet channel 331 and the diversion channel 11 are connected through the groove 131.

[0036] Example 1 The rotating block 33 has a protrusion 332, and the jet channel 331 is L-shaped and passes through the side wall of the rotating block 33 and the side wall of the protrusion 332. The mounting base 1 has an insertion hole 13 that is inserted into the protrusion 332. The water passage 21 is connected to the groove 131 on the side wall of the insertion hole 13. The rotating block 33 is inserted into the mounting base 1 through the protrusion 332 and can rotate relative to the mounting base 1.

[0037] Example 2 Mounting base 1 has a protrusion 332, which is connected to water channel 21 and has a through hole on its side wall. Rotating block 33 has an insertion hole 13 that is inserted into the protrusion 332. Jet channel 331 is connected to groove 131 on the side wall of insertion hole 13. Rotating block 33 is fitted onto protrusion 332 and can rotate relative to mounting base 1.

[0038] By providing the protrusion 332 and the insertion hole 13, the connection structure between the rotating block 33 and the mounting base 1 can be simplified, making it easier to assemble and use the rotating block 33. Furthermore, the protrusion 332 can provide axial support for the rotating block 33, ensuring stable rotation of the rotating block 33.

[0039] Furthermore, a sealing assembly is provided between the protrusion 332 and the inner wall of the insertion hole 13. Optionally, the sealing assembly may be a sealing structure, oil seal, etc., provided on the outer peripheral wall of the protrusion 332 and the inner peripheral wall of the groove 131, which will not be described in detail here.

[0040] By setting a sealing component, the sealing component can seal the gap between the protrusion 332 and the inner wall of the insertion hole 13, and the sealing medium leaks from the gap between the rotating block 33 and the mounting base 1, effectively improving the sealing performance of the jet assembly.

[0041] Reference Figure 6 As shown, it can be understood that the sealing assembly includes two sealing rings 14, which are spaced apart on both sides of the groove 131 along the depth direction of the insertion hole 13.

[0042] By setting two sealing rings 14 on both sides of the groove 131, the two sealing rings 14 cooperate to separate the groove 131 from the external space, ensuring that the medium can only continue to flow into the jet channel 331 after flowing into the groove 131. While ensuring the sealing performance of the sealing component, the cost of using the sealing component is reduced, making it convenient for users to replace and use, and further extending the service life of the jet module.

[0043] Furthermore, the extension line of the center line of the nozzle body 34 does not intersect with the center line of the main shaft 2, that is, within the adjustable rotation range of the nozzle 3, the force line of the reaction force never passes through the rotation center of the mounting base 1.

[0044] By rationally determining the initial angle of the nozzle 3 and the central angle of the gear section 311, the force line of the nozzle 3 can be controlled to never pass through the rotation center of the mounting base 1, thereby avoiding the rotation "dead point" of the mounting base 1, ensuring that the torque of the jet module is never zero, and effectively improving the structural rationality of the jet module.

[0045] Reference Figure 7 As shown, a three-dimensional rotating nozzle according to an embodiment of this application includes a housing 5, a water inlet rod 6, a bevel gear assembly, and the aforementioned nozzle jet module. The water inlet rod 6 is perpendicular to the main shaft 2. The bevel gear assembly includes a first bevel gear 22 disposed at the end of the main shaft 2 away from the mounting base 1 and a second bevel gear 61 disposed on the water inlet rod 6. The main shaft 2 and the water inlet rod 6 are connected by transmission through the bevel gear assembly and are both rotatably connected to the housing 5. The water inlet rod 6 is provided with a water inlet channel communicating with the water passage 21. Since the sealing structure, i.e., the bearing structure, inside the three-dimensional rotating nozzle is a mature technology and is not the focus of this application, it will not be described in detail here.

[0046] Understandably, by adjusting the angle of the nozzle 3, there is no need to set up a complex deceleration structure or electromagnetic structure inside the housing 5. The rotation speed of the jet module and the overall rotation speed of the three-dimensional rotating nozzle can be quickly adjusted, simplifying the structure of the nozzle 3 and improving the ease of use of the nozzle 3.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
