Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and in particular to a three-dimensional spatial cleaning device with adjustable rotation speed. Background Technology

[0002] In industrial sectors such as chemical, food, pharmaceutical, and storage and transportation, large storage tanks, reaction vessels, tank trucks, and other containers accumulate residues, crystals, sediments, or microbial fouling on their inner walls after each batch of materials has been used. To ensure the quality of the next batch of products, prevent cross-contamination, and maintain the heat transfer efficiency and safe operation of the equipment, these containers must be thoroughly and efficiently cleaned.

[0003] Currently, traditional fixed spray ball mechanisms have limited cleaning coverage, leaving blind spots and resulting in unsatisfactory cleaning effects. Mechanical tank washers require external power sources such as motors or pneumatic motors, posing risks of cable entanglement, seal leaks, and potential electrical sparks. Hydraulic-driven rotary nozzles require no external power and offer high safety; however, traditional hydraulic nozzles typically rotate in a single dimension, resulting in repetitive cleaning trajectories and difficulty in covering complex internal cavities. Their rotational speed is usually strongly correlated with inlet water pressure, making speed adjustment under constant pressure impossible. Summary of the Invention

[0007] Furthermore, the input pipe assembly also includes a water inlet pipe and a water inlet connector; one end of the water inlet pipe is rotatably and sealed in the first mounting hole, the worm gear is disposed in the first mounting hole and coaxially fixed outside the water inlet pipe, and the other end of the water inlet pipe is fixedly connected to the water inlet connector, which is connected to a water pump disposed outside the cavity to be cleaned through a pipeline for inputting pressurized cleaning fluid.

[0008] Furthermore, on both sides of the fixed worm gear on the water inlet pipe, the bushings provide rotatable support to the wall of the first mounting hole. An end face bearing is installed on the outside of the outer bushing, with the inner end of the end face bearing contacting the outer shoulder on the water inlet pipe. An end cap is installed on the outer side of the end face bearing, and a sealing ring is installed between the outer ring of the end cap and the corresponding part of the wall of the first mounting hole. The end cap is axially limited by an externally installed hole retaining ring. A double-lip sealing ring is also installed on the inner side of the outer bushing.

[0009] Furthermore, the two water outlets on the nozzle are connected to a transverse water outlet through hole located inside the nozzle; a water passage hole is provided inside the center of the main shaft, one end of which is perpendicularly connected to a plurality of water inlets arranged radially, and the other end of which is connected to a water outlet through hole arranged radially; the water inlets on the main shaft are aligned with the inner port of the water inlet pipe, so that the cleaning fluid flowing in from the water inlet pipe enters the water passage hole of the main shaft through the water inlet hole; the transverse water outlet through hole on the nozzle is connected to the water outlet through hole on the main shaft, so that the cleaning fluid is sprayed out through the two water outlets.

This fundamentally eliminates the risk of electrical sparks, making it safer to use.

[0013] 2. The device of this invention employs a parallel gear, worm gear, and bevel gear transmission system internally.

Detailed Implementation

[0018] The structure of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to an adjustable-speed spatial three-dimensional cleaning device. Figures 1-4 The invention features a housing assembly 8, an input pipe assembly 2, a main shaft assembly 4, a worm shaft 3, a spur gear shaft 5, a bevel gear shaft 6, and a speed adjustment assembly 7.

[0020] The housing assembly consists of a housing body 8-1 and a side cover 8-2. A side cover mounting opening and mounting holes are provided on one side of the housing body to allow the main spindle assembly, worm gear shaft, spur gear shaft, and bevel gear shaft to be installed within the inner cavity of the housing assembly. After installation, the side cover plate is inserted into the side cover mounting opening, and screws are installed at the four corners to achieve a fixed connection with the housing body, forming a closed housing. A main spindle mounting post 8-1-1 is vertically positioned in the inner cavity of the housing body, corresponding to the center of the side cover mounting opening, with a main spindle hole at its center. Mounting holes perpendicular to the main spindle mounting post are provided at both ends of the housing body. One mounting hole is used for rotatable installation of the input pipe assembly (first mounting hole), and the other mounting hole is used for installation of the speed adjustment assembly (second mounting hole). The inner end of the first mounting hole is perpendicularly connected to the main spindle hole of the main spindle mounting hole.

[0021] The input pipe assembly is a fixed component, which is fixedly installed in a predetermined position within the cavity to be cleaned. The input pipe assembly mainly includes a water inlet pipe 2-2, a water inlet connector 2-3, and a worm gear 2-1. One end of the water inlet pipe is sealed and rotatably installed in a first mounting hole. The worm gear is disposed in the first mounting hole and coaxially fixed outside the water inlet pipe. The other end of the water inlet pipe is fixedly connected to the water inlet connector, which is connected to a water pump 1 located outside the cavity to be cleaned via a pipeline, for inputting pressurized cleaning fluid.

[0022] The specific fit between the aforementioned water inlet pipe and the first mounting hole can be as follows: The water inlet pipe, located on both sides of the fixed worm gear, is rotatably supported by bushings 2-3 against the wall of the first mounting hole. An end-face bearing 2-5 is installed on the outer side of the outer bushing. The inner end of the end-face bearing contacts the outer shoulder on the water inlet pipe. An end cap 2-6 is installed on the outer side of the end-face bearing. A sealing ring is installed between the outer ring of the end cap and the corresponding part of the wall of the first mounting hole. The end cap is axially limited by an external retaining ring. Additionally, a double-lip sealing ring 2-4 is installed on the inner side of the outer bushing.

[0023] The specific fit between the water inlet pipe and the first mounting hole of the present invention, on the one hand, realizes the rotational support fit between the water inlet pipe and the first mounting hole position of the housing body and the bearing of water pressure force, and on the other hand, ensures a seal and prevents water from overflowing.

[0024] The main shaft assembly consists of a main shaft 4-2, a nozzle 4-3, and a central gear 4-1. One end of the main shaft is the nozzle mounting end, and the other end is the central gear mounting end. A water passage hole is provided inside the center of the main shaft. One end of the water passage hole is perpendicularly connected to multiple radially arranged water inlets, and the other end is connected to a radially arranged water outlet. The nozzle has two water outlets offset at 180°, and these two water outlets are connected to a transverse water outlet located inside the nozzle.

[0025] The main shaft is rotatably and sealed within the main shaft mounting post's spindle hole with the nozzle mounting end located outside the housing body. The water inlet on the main shaft is aligned with the inner port of the water inlet pipe, allowing the cleaning fluid flowing in from the water inlet pipe to enter the water passage hole of the main shaft through the water inlet. The nozzle sealing kit is fixed to the nozzle mounting end of the main shaft with screws, and the transverse water outlet hole on the nozzle communicates with the water outlet hole on the main shaft, allowing the cleaning fluid to be sprayed out through two outlets.

[0026] The central gear assembly is fixed to the central gear mounting end on the main shaft, which is the end closest to the side cover. A blind hole is provided on the end face of the main shaft near the side cover, and an exposed ball is installed in the blind hole. The ball rolls in contact with the inner end face of the side cover for axial support and limiting.

[0027] The specific fit between the main shaft and the main shaft mounting column in the main shaft hole is as follows: the part of the main shaft near both ends is rotatably supported and fitted with the hole wall of the main shaft hole through a bushing, and sealing rings are installed on both sides of the water inlet on the main shaft between the main shaft and the hole wall of the main shaft hole to achieve sealing, so as to ensure that the cleaning fluid can smoothly enter the main shaft through the water inlet pipe and finally be delivered to the nozzle and sprayed out through the water outlet.

[0028] The worm shaft consists of a worm portion 3-1 and a spur tooth portion 3-2. The spur gear shaft has a first spur tooth portion 5-1 and a second spur tooth portion 5-2 at both ends. The bevel gear shaft has a bevel tooth portion 6-2 and a spur tooth portion 6-1 at both ends. The worm shaft, spur gear shaft, and bevel gear shaft are rotatably mounted in the inner cavity of the housing body via bearings at both ends, and are arranged parallel to the main shaft. The worm portion of the worm shaft meshes with the worm wheel, and the spur tooth portion of the worm shaft meshes with the central gear. The first spur tooth portion of the spur gear shaft meshes with the central gear, and the first spur tooth portion of the spur gear shaft meshes with the spur tooth portion of the bevel gear shaft.

[0029] The speed regulating assembly includes a speed regulating bolt 7-2, a vortex cup 7-3, a magnet ring 7-4, and a final-stage bevel gear shaft 7-5. The final-stage bevel gear shaft is rotatably supported by bearings and installed in the second mounting hole of the housing body, with the bevel teeth of the final-stage bevel gear shaft meshing with the bevel teeth of the bevel gear shaft. The final-stage bevel gear shaft is coaxially and fixedly connected to the magnet ring via an intermediate connecting bracket. The vortex cup is coaxially and loosely fitted around the magnet ring, and a threaded hole is provided at the center of the vortex cup, forming a threaded connection with the inner end of the speed regulating bolt. The outer end of the speed regulating bolt is rotatably supported on a bolt support cover 7-1 in an axially limited manner, and the bolt support cover is fixedly connected to the corresponding end of the housing body.

[0030] To ensure that the vortex cup only moves axially when adjusting the speed regulating bolt, a radially square limiting post can be set on the main body of the housing, and an axial guide groove can be set on the outer side of the vortex cup. The inner end of the limiting post is inserted into the guide groove, which can limit the rotation of the vortex cup in the circumferential direction.

[0031] This speed adjustment component can drive the vortex cup to move axially by rotating the speed adjustment bolt, thereby changing the coverage area of ​​the vortex cup on the magnet ring, thus changing the resistance of the vortex cup on the magnet ring, and consequently changing the rotation speed of the main shaft, thus realizing stepless speed regulation of the device.

[0032] The working principle of this adjustable-speed three-dimensional spatial cleaning device is as follows: The external high-pressure water pipe is connected to the input pipe assembly and suspended in the tank, allowing high-pressure water to flow into the device. The high-pressure water flows through the main shaft assembly and exits through the nozzle, driving the main shaft to rotate. This motion and torque drive the worm shaft, spur gear shaft, bevel gear shaft, and final-stage bevel gear shaft to rotate via the central large gear. Since the worm gear remains stationary, the entire device can rotate around the central axis of the input pipe. Through the combined motion of these two systems, a three-dimensional spatial cleaning effect is achieved, resulting in thorough cleaning without blind spots. Simultaneously, a speed adjustment component is provided; by adjusting the speed adjustment bolt, the rotational speed of the main shaft assembly and the entire device can be controlled.

[0033] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
