Description

Technical Field

[0001] The invention relates to the technical field of pipe cleaning tooling, and in particular to a vertical aluminum pipe cleaning device. Background Art

[0002] Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is hollow along its entire longitudinal length by extrusion of pure aluminum or aluminum alloy. During the manufacturing process of aluminum tube, impurities such as lubricating oil and aluminum slag will remain inside it, so it needs to be cleaned before assembly.

[0003] It is relatively easy to clean the outer wall of the aluminum tube, but the difficulty lies in cleaning its inner wall. Existing methods for cleaning the inner wall of the aluminum tube include immersion, high-pressure gas cleaning and high-pressure liquid cleaning. The immersion method is to immerse the aluminum tube in the cleaning liquid. The operation is simple, but the cleaning time is long and the cleaning effect is poor. Both high-pressure gas cleaning and high-pressure liquid cleaning use high-pressure fluid to flush the inner wall of the aluminum tube, and use a brush to assist in cleaning. Both have good cleaning efficiency and cleaning effect.

[0004] Most of the existing aluminum tube cleaning devices are horizontal, that is, the device is set horizontally as a whole. The aluminum tube is first suspended and fixed, and then a cleaning shaft is inserted into the aluminum tube. The cleaning shaft is provided with a nozzle and a brush, and the cleaning shaft can rotate around its own axis, so as to achieve the cleaning of the inner wall of the aluminum tube. However, the fluidity of the fluid and impurities in the horizontally arranged aluminum tube is poor, and impurities are easy to accumulate in the tube, affecting the cleaning efficiency. For example, the impurities cleaned in the tube will be pushed by the brush and accumulated on the inner wall of the pipe that has not been cleaned, resulting in a decrease in the cleaning efficiency of the inner wall of the pipe that has not been cleaned. The cleaning shaft often needs to reciprocate multiple times to clean the inner wall of the aluminum tube. Summary of the invention

[0059] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0060] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0061] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0062] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] See also Figure 1 and Figure 2The present invention provides a vertical aluminum tube cleaning device, which includes a clamping and transferring mechanism 1, a cleaning shaft 2, a rotary drive 3 and a water supply box 4; a clamp 11 is provided on the clamping and transferring mechanism 1, and the clamp 11 can clamp the tube body 5; the cleaning shaft 2 and the clamp 11 are coaxially arranged; the clamping and transferring mechanism 1 can drive the tube body 5 to move vertically so that the cleaning shaft 2 extends into or withdraws from the inside of the tube body 5; the rotary drive 3 is connected to the first end of the cleaning shaft 2; the rotary drive 3 can drive the cleaning shaft 2 to rotate around its own axis; a high-pressure nozzle 21 is provided at the second end of the cleaning shaft 2; a connecting pipe 22 is vertically provided inside the cleaning shaft 2; the water supply pipe 41 of the water supply box 4, the connecting pipe 22 and the high-pressure nozzle 21 are connected in sequence; wherein, a plurality of brush assemblies 23 are hinged on the cleaning shaft 2; the brush assembly 23 can swing along the first direction so that the brush assembly 23 can abut against the inner wall of the tube body 5 or the brush assembly 23 can abut against the outer wall of the cleaning shaft 2. by Figure 1 Taking the shown orientation as an example, the first direction is the direction in which the brush assembly 23 swings from the top to the bottom or from the bottom to the top.

[0064] In this embodiment, the clamping and transferring mechanism 1 includes a clamping mechanism and a lifting mechanism; the clamping mechanism includes a cylinder and a clamp 11, and the cylinder drives the clamp 11 to clamp or release the tube body 5; the lifting mechanism is connected to the cylinder, and the lifting mechanism can drive the cylinder to lift vertically, thereby achieving clamping and vertical transfer of the tube body 5. The cleaning shaft 2 extends into the tube body 5 and cleans the inner wall of the tube body 5 in a rotating manner. The rotary drive 3 is an electric motor. The water supply tank 4 provides clean water for the cleaning shaft 2, and drives the cleaning shaft 2 to rotate around its own axis through the rotary drive 3, thereby achieving 360° spraying in the rotating state of the high-pressure nozzle 21, thereby improving the cleaning efficiency of the subsequent brush assembly 23.

[0065] The vertical aluminum tube cleaning device is arranged vertically as a whole. Compared with the horizontal aluminum tube cleaning device, the vertical aluminum tube cleaning device clamps the tube body 5 vertically, and the cleaning axis 2 and the clamp 11 (that is, the tube body 5) are coaxially arranged, which improves the fluidity of the fluid and impurities in the tube body 5, so that the fluid and some impurities can fall naturally, and the fluid can bring out some impurities, effectively avoiding the accumulation of impurities in the tube body 5 and reducing the cleaning efficiency of the brush assembly 23.

[0066] The brush assembly 23 can swing along the first direction. When the cleaning shaft 2 rotates, the brush assembly 23 swings around its hinge axis under the influence of centrifugal force, fully contacts and cleans the inner wall of the tube body 5, and can effectively adapt to the cleaning conditions of the uneven inner wall of the tube body 5, thereby improving the cleaning quality. In addition, the brush assembly 23 can adaptively adjust the brushing outer diameter according to the inner diameter of the processed tube body 5, thereby improving the adaptability of the vertical aluminum tube cleaning device to the cleaning of tube bodies 5 of different sizes. Secondly, when the cleaning shaft 2 does not rotate, the brush assembly 23 is affected by its own gravity and naturally approaches or rests on the outer wall of the cleaning shaft 2, so that the inner wall of the tube body 5 will not contact the brush assembly 23 during the lifting process, thereby effectively preventing impurities adhering to the brush assembly 23 from falling onto the inner wall of the tube body 5, thereby improving the cleaning quality.

[0067] When cleaning, first clamp the tube body 5 vertically on the clamping and transferring mechanism 1. In the extended state, the cleaning shaft 2 extends into the upper end of the tube body 5; the rotary drive 3 drives the cleaning shaft 2 to rotate around its own axis, and the high-pressure nozzle 21 rotates to spray high-pressure water to flush and wet the inner wall of the tube body 5. The brush assembly 23 rotates to clean the wetted inner wall of the tube body 5 until all the brush assemblies 23 extend out of the inner wall of the tube body 5, completing one cleaning of the tube body 5. In the retracted state, the brush assembly 23 rotates to clean the wetted inner wall of the tube body 5 again, and the high-pressure nozzle 21 rotates to spray high-pressure water to flush the impurities on the inner wall of the tube body 5 again until the high-pressure nozzle 21 withdraws from the inner wall of the tube body 5, completing the secondary cleaning of the tube body 5. Finally, the cleaning of the inner wall of the tube body 5 is completed through one reciprocating lifting motion, with high cleaning efficiency and good cleaning quality.

[0068] It should be noted that during the secondary cleaning process, impurities adhered to the brush assembly 23 may fall onto the inner wall of the tube body 5 that has been flushed by the high-pressure nozzle 21. However, since the liquid sprayed by the high-pressure nozzle 21 is high-pressure water, the high-pressure water can flush the impurities that fall onto the inner wall of the tube body 5, thereby ensuring the cleaning quality. Optionally, in the retracted state, the cleaning shaft 2 does not rotate, that is, the brush assembly 23 does not work, and a plurality of spray heads are correspondingly arranged on the high-pressure nozzle 21, so that the high-pressure nozzle 21 can achieve 360° spraying without rotating, so that during the secondary cleaning process, the rotary drive 3 does not need to work, saving processing costs; it can also effectively prevent the impurities adhered to the brush assembly 23 from falling onto the inner wall of the tube body 5 that has been flushed due to centrifugal force, thereby further improving the cleaning quality.

[0069] like Figure 3As shown, a concave block 24 is provided on the cleaning shaft 2; bearings 241 are correspondingly provided on both sides of the inner wall of the concave block 24; the brush assembly 23 includes a brush body 231 and a connecting rod 232; the brush body 231 is provided on the connecting rod 232; and the two ends of the connecting rod 232 are rotatably connected to a pair of bearings 241 in a one-to-one correspondence. In this embodiment, the concave block 24 is hemispherical, and a groove is provided inside the hemisphere, and the size of the groove is adapted to the width and height of the brush body 231. Bearings 241 are correspondingly provided on the two side walls of the groove, so that the connecting rod 232 can rotate in the concave block 24, thereby realizing the swing of the brush body 231 in the first direction. Conventional brushes are generally directly provided on the cleaning shaft 2 and do not have a swinging function. The brush assembly 23 of the present invention effectively cooperates with the cleaning shaft 2, realizes the adaptive adjustment of the brush assembly 23 relative to the inner diameter of the tube body 5, and can effectively brush the dead corners of the inner wall of the tube body 5, thereby improving the cleaning quality.

[0070] See also Figure 4 The brush assembly 23 also includes a clamping member 233; the clamping member 233 includes a V-shaped elastic member 2331 and a clamping block 2332; the bottom surface of the V-shaped elastic member 2331 is arranged on the connecting rod 232; the clamping block 2332 is arranged on the top surface of the V-shaped elastic member 2331; a clamping groove 2411 is provided inside the inner ring of the bearing 241; the clamping block 2332 is clamped with the clamping groove 2411. Specifically, the V-shaped elastic member 2331 has a certain elasticity. When the V-shaped elastic member 2331 is squeezed, the clamping block 2332 descends along with the top surface of the V-shaped elastic member 2331, so that the clamping block 2332 can move to the bottom of the clamping groove 2411, so that the connecting rod 232 can be pulled axially to realize the disassembly and assembly of the V-shaped elastic member 2331. In this embodiment, Figure 3 and Figure 4 As shown, a plurality of clips 233 are arranged around the right side of the connecting rod 232, and an axial sliding margin is left between the left side of the connecting rod 232 and the bearing 241 (or concave block 24) on the left side to facilitate the disassembly and assembly of the brush assembly 23, thereby improving the convenience of replacing the brush assembly 23 and ensuring the cleaning effect of the brush assembly 23.

[0071] like Figure 5As shown, optionally, a sliding block 2333 is provided on the bottom surface of the V-shaped elastic member 2331, and a sliding groove 2321 is provided on the connecting rod 232. The sliding block 2333 and the sliding groove 2321 are connected to each other in an axial sliding manner along the connecting rod 232, so that the convenience of disassembly and assembly of the brush assembly 23 can be improved under the working condition that the axial sliding margin of the connecting rod 232 is not reserved. Among them, the sliding block 2333 and the sliding groove 2321 can be set to be T-shaped, so that the sliding groove 2321 can limit the sliding block 2333 in the radial direction of the connecting rod 232, improve the sliding stability of the two, and further improve the connection strength between the brush assembly 23 and the bearing 241. Further, a guide groove 2412 is provided on the inner ring of the bearing 241 between the inner side of the bearing 241 and the slot 2411. The guide groove 2412 is tilted from high to low from the inside to the outside of the bearing 241 to facilitate operators to quickly identify the position of the slot 2411 and improve the connection convenience between the clamping member 233 and the bearing 241.

[0072] See also Figure 6 , a plurality of spray slots 211 are provided on the high-pressure nozzle 21; the plurality of spray slots 211 are correspondingly connected to the connecting pipe 22; along the jet direction of the high-pressure nozzle 21, the slot size of the spray slot 211 changes from large to small. Compared with the method of setting a plurality of nozzles on the high-pressure nozzle 21, the procurement cost and maintenance cost of setting a plurality of spray slots 211 on the high-pressure nozzle 21 are lower. The liquid in the water supply tank 4 can be sprayed out through the water supply pipe 41, the connecting pipe 22 and the spray slot 211 to flush the inner wall of the tube body 5. The structure of the high-pressure nozzle 21 is simple and practical. On this basis, the slot size of the spray slot 211 is set from large to small, and the fluid flows from the large-diameter end to the small-diameter end to form a high-pressure fluid, which improves the cleaning efficiency of the fluid and the fluidity in the tube body 5.

[0073] See again Figure 1 and Figure 2 , the connecting pipe 22 is a water supply channel; a dynamic seal 25 is provided on the cleaning shaft 2, and the dynamic seal 25 can be selected from existing dynamic seals; the water supply pipe 41 is connected to the water supply channel through the dynamic seal 25. Compared with the way that the connecting pipe 22 is set as a pipeline, the water supply channel is a through hole or a through groove, and no pipeline needs to be buried inside it. The dynamic seal 25 is used to realize the rotation connection between the water supply pipe 41 and the water supply channel, and the two are connected internally, so that the water supply pipe 41 does not need to rotate with the cleaning shaft 2, which simplifies the equipment structure and improves the reliability of the equipment.

[0074] like Figure 7As shown, the vertical aluminum tube cleaning device also includes a cleaning agent supply box 6; the cleaning agent supply box 6 includes a box body 61, a liquid pump 62, a feeding port 63, a water inlet pipe 64 and a water outlet pipe 65; the feeding port 63, the water inlet pipe 64 and the water outlet pipe 65 are connected to the box body 61 accordingly; the liquid pump 62 is built into the box body 61; one end of the water outlet pipe 65 is connected to the liquid pump 62, and the other end is connected to the water supply pipe 41; one end of the water inlet pipe 64 is connected to the box body 61, and the other end is connected to the water supply pipe 41; an electric valve 641 is provided on the water inlet pipe 64. Specifically, the water inlet pipe 64, the water outlet pipe 65 and the water supply pipe 41 are connected. When preparing the cleaning agent, the electric valve 641 is opened, and a reagent that is conducive to cleaning impurities is added through the feeding port 63. The clean water in the water supply tank 4 enters the box body 61 through the water supply pipe 41 and the water inlet pipe 64, and is stirred by manual stirring or stirring with a built-in stirrer in the box body 61, and the box body 61 stores the cleaning agent for standby use. When cleaning agent is needed, the electric valve 641 is closed, the water supply tank 4 does not work, and the liquid pump 62 extracts the cleaning agent and sprays it out through the water outlet pipe 65, the water supply pipe 41, the connecting pipe 22 and the high-pressure nozzle 21 in sequence, so as to spray the cleaning agent on the inner wall of the tube body 5 in the extended state. Compared with the method of directly flushing the inner wall of the tube body 5 with high-pressure water, the brush assembly 23 has a higher cleaning efficiency for the inner wall of the tube body 5 after spraying the cleaning agent. In the retracted state, the electric valve 641 is closed, the liquid pump 62 does not work, and the water supply tank 4 provides clean water for the high-pressure nozzle 21 to flush the inner wall of the tube body 5. By connecting the water inlet pipe 64 and the water outlet pipe 65 in parallel and flexibly opening or closing the electric valve 641, the water supply pipe 41 can provide both clean water and cleaning agent, thereby optimizing the equipment structure and improving the cleaning quality.

[0075] In addition, the first end of the cleaning shaft 2 is provided with a first bevel gear 26; the rotating shaft of the rotary driver 3 is connected to the second bevel gear 31; the cleaning agent supply box 6 is rotatably connected to a stirring shaft 66; a blade 661 is provided on the stirring shaft 66; the stirring shaft 66 is connected to a third bevel gear 662; the first bevel gear 26 is correspondingly meshed with the second bevel gear 31 and the third bevel gear 662 for transmission. Specifically, the first bevel gear 26, the second bevel gear 31 and the third bevel gear 662 are combined for transmission, and the three-axis linkage is realized through the rotary driver 3, which on the one hand improves the rotation stability of the cleaning shaft 2, and on the other hand enables the stirring shaft 66 to rotate synchronously with the cleaning shaft 2, and stirs the clean water and the reagent through the blade 661, and no longer needs to be stirred manually or by adding a stirrer, thereby optimizing the equipment structure and saving processing costs.

[0076] Furthermore, the vertical aluminum tube cleaning device further includes a limit ring 7; the cleaning shaft 2 is rotatably connected to the limit ring 7; and the limit ring 7 can abut against the end surface of the tube body 5. The limit ring 7 can not only improve the stability of the rotation of the cleaning shaft 2, but also limit the highest ascending stroke of the tube body 5, effectively avoiding the situation where the top end of the tube body 5 collides with the first bevel gear 26, thereby improving the reliability of the device during use.

[0077] Secondly, the vertical aluminum tube cleaning device also includes a filter tank 8; the filter tank 8 is arranged below the cleaning shaft 2; and a filter screen 81 is arranged at the top of the filter tank 8. Since the tube body 5 is clamped vertically, the water outflow of the tube body 5 is concentrated at the bottom of the tube body 5, which is convenient for the filter tank 8 to collect sewage. The filter screen 81 can filter out aluminum slag and recycle the aluminum slag.
