Description

Technical Field

[0001] The present invention relates to the technical field of spray cleaning, and particularly to a convenient disassembly type anti-blocking self-cleaning nozzle. Background Technique

[0002] The anti-blocking self-cleaning nozzle can receive gas and water conveyed by the anti-blocking self-cleaning control box and convert them into dry mist with a particle diameter of 1-10 μm and spray it out. According to the control instructions of the system, it sprays towards the dust suppression point. When the dry mist contacts and collides with the dust particles, the dust particles adhere to each other, agglomerate and become larger, and settle under the action of their own gravity, so as to achieve the effect of dust suppression. It can effectively eject various forms of blockages such as welding slag, rust particles, slime, crystal particles, etc. Set the jet air pressure at the outlet of the anti-blocking self-cleaning nozzle within the range of 4-16 bar, better control the working distance difference between the tip of the anti-blocking self-cleaning nozzle and the workpiece, and can obtain a high-momentum and more uniform jet. At the same time, adopt variable cavity technology and high-energy air flow pulse cleaning technology, and then use detection components or fixed-cycle methods to clean the self-cleaning nozzle. The cleaning process is realized under the combined action of the pneumatic control box and the automatic cleaning assembly. Each self-cleaning nozzle can independently complete the self-cleaning action.

[0003] Some existing anti-blocking self-cleaning nozzles need to be connected with connecting pipelines and quick-release joints respectively to the gas path and the water path to achieve the purpose of mixed spraying. During the regular maintenance of the nozzles, personnel need to loosen the quick-release joints connecting the water path and the gas path one by one. When the number of nozzles to be maintained and repaired is large, this operation is extremely cumbersome, which has an adverse effect on the disassembly efficiency of the pipelines. And during use, the pipelines near the quick-release joints are directly suspended in the external environment for a long time, and are extremely vulnerable to external vibrations or accidental touch and dragging and other factors, resulting in shaking. While having the risk of reducing the sealing degree of the pipeline connection end, it also has an adverse effect on the service life of the pipeline body. Summary of the Invention

[0019] 1. When the present invention is in use, by setting a decomposition column, a main frame is rotatably connected to one side of the decomposition column. A hexagonal through hole is arranged inside the decomposition column. The through hole is located on the outer wall of one end of the quick-connect elbow, and its inner diameter is larger than the outer diameter of the quick-connect elbow. An external gear ring is fixedly connected to the outside of the decomposition column. Synchronous belts are connected between adjacent external gear rings.

The main shaft is rotatably connected to the main frame on the outside. A top frame is fixedly connected to the top of the main shaft. A first spring is slidably connected inside the top frame. The outside of the bottom end of the first spring is movably connected to the first spring. The first spring is located between the main shaft and the top frame. The hose carrying the air circuit and the water circuit is matched with the quick-connect head and the quick-connect elbow for docking. Then, pinch the pinch button and lift it inside the top frame until the bottom end of the limit pin disengages from the contact height with the cantilever and the main shaft, releasing the restriction on the position of the cantilever. Then, slide the cantilever inside the main shaft to the position where the secondary jack is directly below the limit pin, release the pinch button, and with the reset of the first spring, push the limit pin into the inside of the secondary jack to fix the horizontal position of the cantilever. Then, hold the outer wall of one end of the cantilever and rotate the main shaft. By driving the first helical gear to mesh with the second helical gear to rotate, the external gear ring is driven to rotate in one direction. Adjacent external gear rings rotate synchronously through the synchronous belt. Through the engagement of the hexagonal through hole inside the decomposition column with the quick-connect terminal at one end of the connecting pipeline, the quick-connect terminal is driven to rotate synchronously on the outside of the quick-connect elbow, completing the synchronous threaded connection between the two ends of the pipeline and the quick-connect elbow.

After the quick-connect terminal is engaged by the hexagonal through hole on its inner wall and rotated, the two sides of the connecting pipeline are released at one time, effectively avoiding the situation where personnel need to loosen each pipeline one by one during the maintenance process before disassembly can be completed. During the process of batch maintenance of the device, the operation process is effectively simplified, the convenience during operation is improved, and the operation efficiency is guaranteed;

[0020] 2. In the present invention, a top sheet is provided. One side of the top sheet is fixedly connected to a sliding arm, one side of the sliding arm is fixedly connected to a sliding bar, the sliding bar is slidably connected to the outside of a guide rail, one side of the guide rail is fixedly connected to a sealing sheet, the other side of the guide rail is meshed with a third bevel gear through symmetrically arranged connections, one side of the third bevel gear is rotatably connected to the sealing sheet, the other side of the third bevel gear is meshed with a first bevel gear, the inside of the sealing sheet is slidably connected to a sliding rod, one side of the sliding rod is fixedly connected to a supporting sheet. During the rotation of the first bevel gear to drive the second bevel gear, on the other side, the third bevel gear is also driven to rotate. Through the meshing of the third bevel gear and the driving teeth, the sliding arm is driven to rise, driving the top sheet to synchronously move upward to lift the pipeline to the height where the top sheet cooperates with the supporting sheet to complete the clamping and limiting of the pipeline. During long-term use, when the pipeline exposed to the external environment is accidentally touched or dragged by an external force, the part of the pipeline body close to the quick-connect elbow can be greatly reduced in the shaking amplitude due to being clamped, ensuring the tightness of the connection between the pipeline and the quick-connect elbow, reducing the risk of loosening, and at the same time ensuring the service life of the pipeline body;

[0021] 3. In the present invention, a tensioning wheel is provided. One side of the tensioning wheel is rotatably connected to a main frame, the other side of the tensioning wheel is rotatably connected to a synchronous belt, and the inner sides of both ends of the synchronous belt are drivingly connected to an external gear ring. Through the support of the tensioning wheel for the suspended part of the synchronous belt, the tightness of the transmission between the synchronous belt and the external gear ring can be effectively ensured during long-term use and under force;

[0022] 4. In the present invention, a limiting ring is provided. The inside of the limiting ring is fixedly connected to a cantilever, and the limiting ring is located on both sides of the main shaft, which can effectively reduce the risk of loosening of the cantilever due to excessive sliding during use.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] A convenient detachable anti-blocking self-cleaning nozzle, including a body mechanism 1, a decomposition mechanism 2 and a pipeline limit mechanism 3

[0036] The body mechanism 1 includes a cylinder 101. Micro quick-releases 102 are symmetrically arranged at the top of the cylinder 101. One side of the cylinder 101 is threadedly connected with a connecting pipe 104 through symmetrically arranged first screws 103. A cleaning needle is arranged inside the connecting pipe 104. One side of the connecting pipe 104 is fixedly connected with a nozzle cap 105. Quick-release elbows 106 are symmetrically arranged on both sides of the nozzle cap 105;

[0037] The decomposition mechanism 2 includes a first helical gear 206 fixedly connected to one side of the main shaft 203. The first helical gear 206 is meshed and connected with an external gear ring 208 through a second helical gear 207. Two external gear rings 208 are symmetrically arranged. The adjacent external gear rings 208 are drivingly connected by a synchronous belt 210. A decomposition column 209 is fixedly connected inside the external gear ring 208. A hexagonal through hole is arranged inside the decomposition column 209. By synchronizing after quick-clamping both ends through the hexagonal through hole, the purpose of disassembling both ends of the pipeline at one time is achieved;

[0038] The pipeline limiting mechanism 3 includes a third helical gear 302 meshed and connected to one side of the first helical gear 206. On one side of the third helical gear 302, there is a sliding arm 304 meshed and connected through symmetrically arranged driving teeth 303. On both sides of the sliding arm 304, there are fixed top pieces 307. By the lifting and limiting of the top pieces 307, the sway amplitude of the part of the pipeline near the connection end is reduced.

[0039] Specific implementation process: Mate the hose carrying the air path and water path with the quick-connect fitting and the quick-connect elbow 106, then pinch the pinch button 6 and lift it in the top frame 204 until the bottom end of the limit pin 205 disengages from the contact height with the cantilever 212 and the main shaft 203, releasing the restriction on the position of the cantilever 212. Then slide the cantilever 212 in the main shaft 203 to the position where the secondary jack 7 is directly below the limit pin 205, release the pinch button 6, and with the reset of the first spring 211, push the limit pin 205 into the inner side of the secondary jack 7 to fix the horizontal position of the cantilever 212. Then hold the outer wall of one end of the cantilever 212 and rotate the main shaft 203. By driving the first helical gear 206 to mesh with the second helical gear 207 to rotate, the outer gear ring 208 is driven to rotate in one direction. The adjacent outer gear rings 208 rotate synchronously through the synchronous belt 210. Through the engagement of the hexagonal through-hole in the decomposition column 209 with the quick-connect terminal at one end of the connecting pipeline, the quick-connect terminal is driven to rotate synchronously outside the quick-connect elbow 106, completing the synchronous threaded connection between the two ends of the pipeline and the quick-connect elbow 106. When disassembly is required, reverse-rotate the first helical gear 206, and in the same way, drive the decomposition column 209 to rotate. After engaging the quick-connect terminal through the hexagonal through-hole in its inner wall and rotating, the connecting pipelines on both sides are released at once, effectively avoiding the situation where personnel need to loosen each pipeline one by one during the maintenance process to complete the disassembly. During the process of batch maintenance of the device, the operation process is effectively simplified, the convenience during operation is improved, the operation efficiency is guaranteed. During the rotation of the first helical gear 206 and the driving of the second helical gear 207, on the other side, the third helical gear 302 is also driven to rotate. Through the meshing of the third helical gear 302 and the driving teeth 303, the sliding arm 304 is driven to rise, driving the top piece 307 to move up synchronously to lift the pipeline to the height where the top piece 307 cooperates with the support piece 309 to complete the clamping and limiting of the pipeline. During the long-term use process, when the pipeline exposed to the external environment is accidentally touched or dragged by an external force, the part of the pipe body near the quick-connect elbow 106 can be greatly reduced in sway amplitude due to being clamped, ensuring the tightness of the connection between the pipeline and the quick-connect elbow 106, reducing the risk of loosening, and at the same time ensuring the service life of the pipe body.

In cooperation with the hexagonal through-hole in the decomposition column 209 to rotate the quick-connect terminal at one end of the pipeline, the pipeline connected with the terminal is threadedly connected to the corresponding quick-connect elbow 106, achieving the purpose of simultaneously disassembling or locking the pipeline when opened.

While effectively improving the sealing performance at the connection between the pipeline and the quick-connect elbow 106, the service life of the pipe body is also guaranteed.
