Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a three-dimensional nozzle and reactor cleaning equipment. Background Art

[0002] The high-pressure, three-dimensional cleaning nozzle for reactors typically has two nozzles in its nozzle module, symmetrically arranged around the center of the nozzle. This allows the reaction force of the two nozzles when spraying water to generate torque and drive the water outlet pipe to rotate. The water outlet pipe rotates through the transmission assembly, driving the entire nozzle head to rotate, allowing the nozzle to move in multiple dimensions within the reactor, ensuring that the jet can cover the reactor's inner wall during movement, achieving the purpose of three-dimensional rotary cleaning. However, existing three-dimensional nozzles typically use high-pressure jets, which makes it easy for the nozzle module to rotate too fast. This not only accelerates damage to the various transmission components within the nozzle, but also leads to problems such as insufficient jet force and uneven jet distribution, affecting the cleaning effect.

[0003] The main method for braking three-dimensional nozzles on the market at present is to set up a magnet connected to the transmission component, and set a rotatable permanent magnet in the brake box. When the three-dimensional nozzle is working, the transmission component drives the magnet to rotate, forming a magnetic field, and achieves braking adjustment through changes in magnetic force; some manufacturers will also add a reduction box on this basis. The reduction box transmission is set between the magnet and the transmission component, and the reduction box gear ratio is changed by changes in the magnetic field to achieve braking adjustment. The combination of permanent magnet and gear reduction can achieve more precise braking adjustment. However, whether it is a permanent magnet structure or a gear pair structure, it will take up a lot of installation space. The transmission structure between the permanent magnet structure or the gear pair structure and the transmission component is also relatively complex, and a separate installation room needs to be set up at the lower end of the nozzle for installation. This will not only increase the weight and volume of the nozzle, making it inconvenient for the nozzle to enter the narrow kettle mouth, but also increase the complexity of the nozzle structure and increase the production and maintenance costs of the three-dimensional nozzle.

[0029] Reference Figures 1 to 4A three-dimensional nozzle provided by an embodiment of the present invention includes a nozzle body 100 and a damping device 200. The nozzle body 100 includes an outer shell 110, a water inlet pipe 120, a water outlet pipe 130 and a transmission assembly 140. The outer shell 110 is composed of a cover body 113 and a shell 114. The cover body 113 and the shell 114 are detachably connected. The water inlet pipe 120 and the water outlet pipe 130 are respectively rotatably installed in the outer shell 110. The water outlet pipe 130 is connected to a nozzle module 150. When the nozzle body sprays a jet, the nozzle module 150 can rotate. The rotating nozzle module 150 can drive the water outlet pipe 130 to rotate and drive the outer shell 110 to rotate through the transmission assembly 140.

[0030] Preferably, the nozzle module 150 is circular, and two nozzles 151 are provided on the outer periphery of the circular nozzle module 150. The two nozzles 151 are symmetrically arranged with the center of the nozzle module 150 as the reference center. The nozzle module 150 is connected to one end of the water outlet pipe 130. When the nozzle body sprays a jet, the nozzle module 150 realizes rotation through the torque formed by the reaction force of the jet sprayed by the two nozzles 151.

[0031] The damping device 200 includes a drive assembly 210 and a damping member 220. The damping member 220 is arranged in the outer shell 110 and around the water inlet pipe 120. The drive assembly 210 can be detachably installed on the outer shell 110 and is arranged around the water inlet pipe 120. Along the radial direction of the water inlet pipe 120, the maximum outer diameter of the drive assembly 210 is smaller than the outer diameter of the outer shell 110. The drive assembly 210 at least partially penetrates into the outer shell 110 and is connected to the damping member 220. The drive assembly 210 can drive the damping member 220 to press against the outer wall of the water inlet pipe 120.

[0032] In some embodiments, the drive assembly 210 can be composed of a push block arranged around the water inlet pipe 120 combined with a transmission structure such as a crank connecting rod, a fan gear connecting rod or a wedge block, so as to convert the external force input along the axial direction of the water inlet pipe 120 into the friction force output of the damping member along the radial direction of the water inlet pipe 120, thereby realizing braking control of the three-dimensional nozzle, which will not be repeated here.

[0033] It can be understood that by setting up the damping device 200, the user can drive the damping member 220 to press against the outer wall of the water inlet pipe 120 through the driving component 210, thereby having a braking effect on the rotating water inlet pipe 120. By controlling the output force of the driving component 210, the braking force can be adjusted, and the rotation speed and jet force of the three-dimensional nozzle can be adjusted.

[0034] The damping member 220 is arranged around the water inlet pipe 120 and directly brakes the water inlet pipe 120, eliminating the traditional permanent magnet structure or the reduction gear set structure. The driving assembly 210 is directly detachably connected to the housing 110 and is arranged around the water inlet pipe 120. At this time, the damping device 200 is concentrated around the water inlet pipe 120, and there is no need to set up an installation room independent of the water inlet pipe 120 and the water outlet pipe 130 for storage and installation. It can effectively simplify the three-dimensional nozzle structure, reduce the volume of the three-dimensional nozzle, can be suitable for small-caliber reactors, and reduce production and maintenance costs.

[0035] Reference Figure 1 and Figure 2 As shown, in this embodiment, a separator block 112 is provided within the housing 110 of the nozzle body 100. A water inlet pipe 120 and a water outlet pipe 130 are respectively disposed on either side of the separator block 112. The separator block 112 is provided with a first through hole 1121. The water inlet pipe 120 is provided with a high-pressure sealed water outlet nozzle 121. The high-pressure sealed water outlet nozzle 121 is snap-fitted to one side of the separator block 112 and communicates with the first through hole 1121. The outer peripheral wall of the high-pressure sealed water outlet nozzle 121 is provided with a water ring 131. The peripheral wall of the water ring 131 is provided with a plurality of second through holes spaced apart. High-pressure sealing rings 132 are respectively provided on either side of the water ring 131. The water ring 131 and the high-pressure sealing ring 132 are snap-fitted to the side of the separator block 112 facing away from the water inlet pipe 120. The water outlet pipe 130 is provided with a water passage, one end of which communicates with the second through hole and the other end communicates with the nozzle 151. In addition, a plurality of bearings are respectively provided on the outer sides of the water inlet pipe 120 and the water outlet pipe 130 to ensure the rotation stability of the water inlet pipe 120 and the water outlet pipe 130 .

[0036] The transmission assembly 140 is located between the water inlet pipe 120 and the water outlet pipe 130. The water inlet pipe 120 is fixed relative to the water outlet pipe 130. The transmission assembly 140 is configured to link the water inlet pipe 120 and the water outlet pipe 130 when the water inlet pipe 120 rotates, so that the water outlet pipe 130 rotates around the water inlet pipe 120 and drives the shell 110 to rotate synchronously.

[0037] Specifically, the transmission assembly 140 can be configured as a transmission structure capable of changing the direction of rotation, such as a worm gear or bevel gear set. In this embodiment, a first bevel gear 141 can be provided at the end of the water inlet pipe 120 near the water outlet pipe 130, and a second bevel gear 142 can be provided at the end of the water outlet pipe 130 away from the nozzle module 150, meshing with the first bevel gear 141, to achieve linkage between the water inlet pipe 120 and the water outlet pipe 130. Users can select the appropriate transmission assembly 140 based on their actual needs, as long as the water inlet pipe 120 and the water outlet pipe 130 rotate synchronously. This will not be further described here.

[0038] Furthermore, the damping member 220 is configured as an elastic friction ring, which can be made of polymer wear-resistant materials, rubber, flexible plastic, etc. The inner wall of the friction ring is provided with an annular protrusion, which abuts against the outer peripheral wall of the water inlet pipe 120.

[0039] By providing the protrusion, the contact area between the friction ring and the outer peripheral wall of the water inlet pipe 120 can be reduced, thereby increasing the braking force exerted by the friction ring on the water inlet pipe 120 and enhancing the braking effect of the damping device 200.

[0040] Reference Figure 1 and Figure 2 As shown, it can be understood that the driving assembly 210 includes a propeller 211 and a base 212. The propeller 211 is arranged around the water inlet pipe 120. The propeller 211 is installed in the outer shell 110 and can move along the axial direction of the water inlet pipe 120. The end faces of the propeller 211 and the damping member 220 are abutted. The base 212 is arranged in the outer shell 110 and around the damping member 220. The base 212 is provided with a first conical surface 2121, and the damping member 220 is provided with a second conical surface 221 matching the first conical surface 2121. The propeller 211 is moved and the friction force of the damping member 220 is adjusted by cooperating with the first conical surface 2121 and the second conical surface 221.

[0041] Specifically, the user pushes the propeller 211 along the axial direction of the water inlet pipe 120, and the stress between the propeller 211 and the damping member 220 increases. Under the action of the reaction force of the first cone surface 2121, the damping member 220 grips the outer wall of the water inlet pipe 120, thereby increasing the friction force of the damping member 220 on the water inlet pipe 120; the user pulls out the propeller 211 along the axial direction of the water inlet pipe 120, and the stress between the propeller 211 and the damping member 220 decreases, the reaction force of the first cone surface 2121 decreases, and the damping member 220 loosens the outer wall of the water inlet pipe 120, thereby reducing the friction force of the damping member 220 on the water inlet pipe 120.

[0042] In some embodiments, the propulsion member 211 may include a cylinder that is interference fit with the outer shell 110 , and the pressure plate 2112 is pressed by the friction between the outer wall of the pressure cover 2111 and the inner wall of the outer shell 110 , which will not be described in detail here.

[0043] By setting the propeller 211 and the base 212, under the action of the first conical surface 2121 of the base 212 and the second conical surface 221 of the damping member 220, the linear movement of the propeller 211 is converted into the scaling change of the damping member 220, which can effectively simplify the structure of the damping device 200, reduce the height of the damping device 200, greatly reduce the volume of the three-dimensional nozzle, and simplify the braking adjustment steps, making it more convenient for users to use.

[0044] It should be noted that the inclination angles of the first conical surface 2121 and the second conical surface 221 can be selectively set. Assuming the thrust of the propulsion member 211 is the same, the greater the inclination angle of the first conical surface 2121 and the second conical surface 221, the greater the frictional force exerted by the damping member 220 on the water inlet pipe 120. The smaller the inclination angle of the first conical surface 2121 and the second conical surface 221, the smaller the frictional force exerted by the damping member 220 on the water inlet pipe 120. There is no specific limitation on the inclination angles of the first conical surface 2121 and the second conical surface 221. Users can select appropriate inclination angles based on actual needs, as long as they ensure stable braking of the water inlet pipe 120.

[0045] Reference Figure 2 As shown, it can be understood that the propulsion member 211 includes a gland 2111 and a pressure plate 2112. The gland 2111, the pressure plate 2112 and the damping member 220 are arranged in sequence along the axial direction of the water inlet pipe 120. The gland 2111 is provided with a central hole for the water inlet pipe 120 to pass through. The pressure plate 2112 is arranged around the water inlet pipe 120 and abuts against the damping member 220. The gland 2111 is threadedly matched with the housing 110, that is, the outer peripheral wall of the gland 2111 is provided with an external thread, and the inner peripheral wall of the housing 110 is provided with an internal thread matching the external thread. The gland 2111 is connected or abutted with the pressure plate 2112. Specifically, the gland 2111 can be integrally formed with the pressure plate 2112, or can be detachably connected to the pressure plate 2112 by screwing, snapping, plugging, etc. The gland 2111 can abut against the end of the pressure plate 2112 facing the damping member 220. No further details are given here.

[0046] By rotating the gland 2111, the user can control the gland 2111 to move toward or away from the damping element 220 along the axis of the water inlet pipe 120. The gland 2111 presses against the damping element 220 via the pressure plate 2112, achieving braking adjustment. By providing the gland 2111 with a threaded fit on the housing 110, on the one hand, when the user rotates the gland 2111 one turn, the pressure plate 2112 moves one thread pitch, allowing the user to precisely control the magnitude of the friction force and improving the accuracy of the damping device 200. On the other hand, the internal and external threads cooperate to ensure that the gland 2111 can withstand the high pressure impact inside the housing 110 when the three-dimensional nozzle is in operation, significantly improving the installation stability of the gland 2111 and enhancing the airtightness of the housing 110.

[0047] Preferably, an elastic member 2113 is provided between the pressure cover 2111 and the pressure plate 2112. The elastic member 2113 can be a spring, a rubber column, etc. The elastic member 2113 is arranged around the water inlet pipe 120, and the pressure cover 2111 is in contact with the pressure plate 2112 through the elastic member 2113.

[0048] During operation of the three-dimensional sprinkler, the damping member 220 presses against the rotating water inlet pipe 120, causing a certain degree of wear, which reduces the frictional force exerted by the damping member 220 on the water inlet pipe 120. By providing the elastic member 2113, after the damping member 220 wears, the elastic force exerted by the elastic member 2113 on the pressure plate 2112 can press against the damping member 220, thereby compensating for the frictional force reduced by the damping member 220, allowing the damping member 220 to wear to a certain extent, ensuring the braking effect of the damping device 200, and improving the operational stability of the damping device 200.

[0049] Preferably, the elastic member 2113 can be configured as a wave spring. The ring-shaped shape of the wave spring can facilitate the user to assemble and use the elastic member 2113 , thereby effectively improving the structural rationality of the damping device 200 .

[0050] Furthermore, two wave springs can be provided, and the two wave springs are arranged opposite to each other (ie, the wave crests of the two wave springs abut against each other), thereby greatly increasing the abutting force of the elastic member 2113 and enhancing the braking effect of the damping device 200.

[0051] In addition, in some embodiments, a first positioning groove 2116 is provided on the side of the pressure cover 2111 facing the damping member 220, and a second positioning groove 2117 is formed between the side of the pressure plate 2112 facing away from the damping member 220 and the inner wall of the pressure cover 2111. The elastic member 2113 is limitedly installed between the first positioning groove 2116 and the second positioning groove 2117, thereby effectively improving the installation stability of the elastic member 2113 and improving the overall structural tightness of the damping device 200.

[0052] Reference Figures 1 to 3 As shown, it is understood that the nozzle body 100 further includes a locking member 160, which is detachably connected to the propulsion member 211 and is used to lock the propulsion member 211. In some embodiments, the locking member 160 can be a cover connected to the housing 110 and engaged with the propulsion member 211, and the cover and the housing 110 cooperate to lock the propulsion member 211.

[0053] By setting the locking member 160, the user can install the locking member 160 after adjusting the friction force through the pusher 211, thereby preventing the locking member 160 from loosening, rotating, and other problems due to internal high-pressure impact when the three-dimensional nozzle is working, effectively improving the installation stability of the pusher 211 and improving the structural stability of the three-dimensional nozzle.

[0054] Reference Figure 2As shown, it can be understood that the portion of the pusher 211 passing through the outer shell 110 is provided with an external thread (when the pusher 211 is set as a pressure cover 2111 and a pressure plate 2112, the portion of the pressure cover 2111 passing through the outer shell 110 and the portion passing through the outer shell 110 are both provided with external threads), and the locking member 160 is configured as a locking nut, and the locking nut is threadedly matched with the portion of the pusher 211 passing through the outer shell 110 and abuts against the outer shell 110.

[0055] The locking member 160 is configured as a locking nut, which is threadedly engaged with the propeller 211 and abuts against the housing 110. At this point, the stress between the locking nut and the housing 110 acts on the propeller 211, increasing the friction force on the propeller 211 and further improving the installation stability of the propeller 211. When the propeller 211 is equipped with a gland 2111 that is threadedly engaged with the housing 110, the locking nut can act similarly to a tightening nut, significantly increasing the friction between the gland 2111 and the housing 110. This prevents the gland 2111 from loosening or rotating during operation of the 3D nozzle, which could affect the braking of the damping device 200 and improve the operating stability of the 3D nozzle.

[0056] Reference Figure 2 and Figure 4 As shown, it can be understood that a flange portion 2114 is provided on the side of the pressure plate 2112 facing the damping member 220 , and the flange portion 2114 is surrounded to form a limiting groove 2115 , and the damping member 220 is snap-fitted with the limiting groove 2115 .

[0057] By setting a limiting groove 2115, the side wall of the limiting groove 2115 cooperates with the first conical surface 2121 to limit the outward expansion and deformation of the damping member 220, ensuring that when the pressure plate 2112 presses against the damping member 220, the damping member 220 contracts and deforms inward, so that the pressure of the pressure plate 2112 can be concentrated and converted to the protrusion to grip the water inlet pipe 120, reducing the pressure loss of the pressure plate 2112 and further increasing the friction force of the damping member 220 on the water inlet pipe 120.

[0058] Continue to refer to Figure 2 and Figure 4 As shown, it can be understood that the outer peripheral wall of the base 212 is provided with a positioning portion 2122, which is a frustum structure arranged around the base 212, and the inner peripheral wall of the shell 110 is provided with an annular positioning step 111, and the positioning portion 2122 and the positioning step 111 are in contact with each other.

[0059] By setting the positioning portion 2122 and the positioning step 111, it is convenient for the user to position the installation base 212, and to install subsequent damping members 220, pressure plates 2112, pressure covers 2111 and other propulsion members 211 based on the base 212, thereby improving the assembly efficiency of the damping device 200, and at the same time avoiding problems such as the damping member 220 caused by loosening and slipping of the base 212 during the movement of the propulsion member 211, thereby effectively improving the installation stability of the damping device 200.

[0060] The utility model also provides a reactor cleaning device, comprising the above-mentioned three-dimensional nozzle.
