Description

Technical Field

[0001] The present application relates to the technical field of pipe cleaning auxiliary equipment, and in particular to a pipe inner wall degreasing device. Background Art

[0002] Extra-long stainless steel cold-drawn tube is a stainless steel tube processed by precision cold-drawing process, usually with long length and high-precision size. The outer diameter of the pipe is generally between 6mm and 940mm. Common standard lengths are 6 meters, 9 meters, 12 meters, etc. Some extra-long stainless steel cold-drawn tubes can reach 15 meters or even longer. After cold drawing, the steel may be lubricated with grease to prevent surface rust or facilitate subsequent processing. These greases may remain on the inner wall of the pipe. Therefore, it is necessary to clean the inner wall of the pipe after production.

[0003] In the related technologies, pipes are cleaned mainly by manual brushing, chemical immersion and other methods. With the advancement of automation technology and new materials science, cleaning methods such as steam cleaning and ultrasonic cleaning have gradually emerged. Steam cleaning mainly uses the heat energy and impact force of high-temperature steam to remove grease from the inner wall of pipes. High-temperature steam can soften and melt grease, and the impact force of steam can strip grease from the inner wall of pipes. In ultrasonic cleaning, ultrasonic waves generate high-frequency vibrations in a water-based detergent or a mixture of organic solvents and water to form tiny cavitation bubbles. When the bubbles burst on the inner wall surface of the pipe, they will generate a strong impact force to strip grease from the inner wall surface of the pipe.

[0004] Regarding the above-mentioned related technologies, most of the equipment can usually only meet the cleaning tasks of short straight pipes with specific size specifications or simple shapes. The length of the extra-long stainless steel cold-drawn pipe is special, so it is usually rolled up on the pipe rack in a coiled form. The bending degree of the pipe is large, so the equipment in the related technology cannot effectively remove the grease residue on the inner wall of the pipe, which is time-consuming and labor-intensive and has low cleaning efficiency. Summary of the invention

[0005] In order to thoroughly degrease the inner wall of an extra-long stainless steel cold-drawn tube, the present application provides a tube inner wall degreasing device.

[0006] The present application provides a pipe inner wall degreasing device that adopts the following technical solution: A pipe inner wall degreasing device comprises a cabinet body, an operating table arranged on one side of the cabinet body, a first cleaning mechanism arranged on the operating table and the cabinet body and used for degreasing the inside of the pipe to be cleaned, and two cleaning pipes respectively used for connecting two ends of the pipe to be cleaned; The first cleaning mechanism includes a first water tank disposed inside the cabinet body and used to hold degreasing liquid, a first liquid outlet pipe assembly disposed on the operating table and connected to the first water tank, and the ends of the two cleaning pipes away from the connection with the pipes to be cleaned are both connected to the first liquid outlet pipe assembly.

[0007] By adopting the above technical solution, for pipes of special length and usually in a coiled form, such as super-long stainless steel cold-drawn pipes, the device connects the two ends of the pipe to be cleaned through two cleaning pipes, and uses the first liquid outlet pipe assembly connected to the first water tank to allow the degreasing liquid to circulate inside the pipe, solving the cleaning problem caused by the length and bending shape of super-long pipes, and penetrating into various positions inside the pipe. The two cleaning pipes are connected to the first liquid outlet pipe assembly, so that the degreasing liquid can circulate inside the pipe, and the circulating cleaning method can make full use of the degreasing liquid to continuously flush the grease on the inner wall of the pipe, thereby enhancing the degreasing effect.

[0008] Furthermore, the first cleaning mechanism also includes a bubble ball for scrubbing the inner wall of the pipe, a ball launching tube for launching the bubble ball, and a delivery tube for connecting the ball launching tube and the liquid outlet pipe assembly and for the bubble ball to pass through, the ball launching tube has a cylinder body and a cover body for covering the cylinder body, the cover body is provided with a bubble ball inlet for inserting the bubble ball, the delivery tube is connected to the cover body at one end away from the connection with the liquid outlet pipe assembly and is connected to the inside of the cylinder body, and the operating table is provided with a support bracket for mounting the cylinder body.

[0009] By adopting the above technical solution, the flow of degreasing liquid alone may not be able to completely remove the stubborn grease residue inside the extra-long stainless steel cold-drawn tube, while the setting of the bubble ball can provide a physical scrubbing method, penetrating into various parts of the inner wall of the tube. In some complex bends or areas where the degreasing liquid is difficult to fully act, the bubble ball rolls inside the tube with the flow of the degreasing liquid to fully scrub the inner wall, making up for the shortcomings of simple chemical degreasing and improving the thoroughness of degreasing. The cover of the ball-serving barrel and the bubble ball inlet on the cover make it easy for the operator to insert the bubble ball into the ball-serving barrel, and the delivery pipe connects the ball-serving barrel and the liquid outlet pipe assembly to realize the integration of the bubble ball and the degreasing liquid delivery path, so that the bubble ball can smoothly enter the inside of the tube along the flow direction of the degreasing liquid, ensuring that the two cleaning methods are carried out simultaneously inside the tube.

[0010] Furthermore, the cylinder is rotatably connected to the upper side of the support frame, and a plurality of launching slots for placing the bulbs are circumferentially arranged inside the cylinder, and the openings of the launching slots are aligned with the bulb inlet / the delivery pipe.

[0011] By adopting the above technical solution, the setting of multiple launch slots facilitates the loading of multiple bulbs at a time. The launch slot opening is aligned with the bulb entrance, which facilitates the bulb to be directly loaded into the launch slot from the bulb entrance. When the bulb needs to be launched, the launch slot opening can be aligned with the delivery tube to ensure that the bulb smoothly enters the delivery tube and is transported to the inside of the pipe, making the entire loading and launching process smooth and coherent. For longer pipes, bulbs can be launched from different launch slots in different time periods to ensure that the inner wall of the entire pipe can be fully scrubbed.

[0012] Furthermore, a first recovery cylinder for recovering the bulb is provided on the side wall of the cabinet body above the first recovery mechanism. The first recovery cylinder is interconnected with the first liquid outlet pipe assembly and the first water tank. The first recovery cylinder is internally provided with a filter plate for intercepting the bulb.

[0013] By adopting the above technical solution, the first recovery cylinder can recycle the used bulbs, and after the degreasing operation of the inner wall of the pipe is completed, the bulbs can be intercepted by the first recovery cylinder. The first recovery cylinder is connected to the first water tank and is provided with a filter disc inside. The filter disc can effectively intercept the bulbs in the recovery cylinder to prevent the bulbs from entering the first water tank, avoid the blockage problem caused by the accumulation of bulbs in the water tank, ensure the smooth flow of the degreasing liquid in the circulation system composed of the first water tank, the first liquid outlet pipe assembly, etc., and also realize the reuse of the bulbs, thereby improving the utilization efficiency of resources.

[0014] Furthermore, the first liquid outlet pipe assembly includes a main liquid outlet pipe connected to the first water tank and a first branch pipe and a second branch pipe connected to the main liquid outlet pipe. The two cleaning pipes are connected to the first branch pipe and the second branch pipe one by one. The first branch pipe and the second branch pipe are both provided with solenoid valves for controlling the flow direction of the internal liquid.

[0015] By adopting the above technical solution, the solenoid valves provided on the first branch pipe and the second branch pipe can accurately control the degreasing liquid to flow from the first water tank through the total liquid outlet pipe into the corresponding cleaning pipe. When performing forward cleaning, the solenoid valve on one of the branches can be opened to allow the degreasing liquid to enter the pipe to be cleaned from one end of the cleaning pipe and clean the pipe according to the normal flow direction of the pipe. For extra-long stainless steel cold-drawn pipes, due to their length and bending shape, during forward cleaning, cleaning dead corners may be formed at the bends of the pipes or the rough areas on the inner wall, and grease residues are difficult to completely remove. By controlling the solenoid valve to switch the flow direction of the cleaning liquid and performing reverse cleaning, the cleaning liquid can enter from the other end of the pipe, reversely flush the inner wall of the pipe, and remove grease and impurities in the dead corners that are difficult to remove by forward cleaning, further improving the thoroughness of cleaning, reducing cleaning blind spots, and improving the comprehensiveness of degreasing the inner wall of the pipe.

[0016] Furthermore, the operating table is provided with a second cleaning mechanism for rinsing the inner wall of the pipe at a position adjacent to the first cleaning mechanism; The second cleaning mechanism is arranged inside the cabinet body and is used for a second water tank for holding a rinsing liquid, a second liquid outlet pipe and a second recovery pipe are arranged on the operating table and connected to the second water tank, and the second liquid outlet pipe and the second recovery pipe both have connection ports for connecting the cleaning pipe.

[0017] By adopting the above technical solution, the second cleaning mechanism is set up so that the cleaning process of the pipe fitting can be divided into two clear steps: degreasing and rinsing. After the first cleaning mechanism is used to complete the degreasing of the inner wall of the pipe fitting, the second cleaning mechanism can use the rinsing liquid to further treat the inner wall of the pipe fitting, which can effectively remove the degreasing liquid remaining on the inner wall of the pipe fitting and the products of the reaction between the degreasing liquid and grease that may exist, thereby achieving more delicate cleaning and improving the cleaning quality of the inner wall of the pipe fitting.

[0018] Furthermore, the second recovery pipe is provided with a second recovery cylinder for recovering the bulb, and the second recovery cylinder is provided with a filter net for intercepting the bulb.

[0019] By adopting the above technical solution, the filter in the second recovery cylinder can effectively intercept the bulbs, prevent the bulbs from entering the second recovery pipe and the subsequent recovery system, avoid the bulbs from clogging the pipes and equipment, and ensure the normal operation of the second cleaning mechanism. The second recovery cylinder can recycle the bulbs used for rinsing, realize the reuse of the bulbs, and improve the efficiency of the bulbs.

[0020] Furthermore, the cabinet body is provided with two booster pumps respectively used to communicate with the first water tank and the second water tank, and the cabinet body is provided with a diaphragm pump interconnected with the first liquid outlet pipe assembly and the second recovery pipe below the operating table.

[0021] By adopting the above technical solution, by setting two pressure pumps connected to the first water tank and the second water tank respectively, the degreasing liquid / rinsing liquid in the corresponding water tank can be pressurized. When cleaning the extra-long stainless steel cold-drawn tube, due to the long length of the pipe fittings and possible bending, the pressure pump can provide sufficient power for the cleaning liquid to ensure that the degreasing liquid and the rinsing liquid can smoothly enter and flow through the inside of the pipe fittings, overcome the resistance of the pipe fittings, and increase the flow rate and flow of the liquid in the pipe fittings, thereby enhancing the cleaning effect and ensuring that the cleaning liquid can reach all parts of the pipe fittings, including areas that are difficult to reach due to their length and shape. The diaphragm pump pumps the degreasing liquid / rinsing liquid in the pipeline into the corresponding water tank, provides power for the circulation of the cleaning liquid, helps to maintain the circulation of the cleaning liquid, and forms a stable circulation system between the pipe fittings and the water tank, so that the cleaning liquid continuously flushes and cleans the inner wall of the pipe fittings, improves the cleaning efficiency, and avoids the problem of poor cleaning effect caused by poor flow of the cleaning liquid.

[0022] Furthermore, an air pump and a heater for heating air are provided inside the cabinet body below the operating table, and one end of the heater away from the air pump is connected to the second liquid outlet pipe.

[0023] By adopting the above technical solution, an air pump and a heater are set up to generate a high-temperature and high-pressure airflow, which is similar to the principle of a hair dryer. The high-temperature and high-pressure airflow is introduced into the second liquid outlet pipe and then into the interior of the pipe. The residual liquid in the pipe can be quickly evaporated, including the rinse liquid after rinsing or other liquids in the cleaning process, thereby shortening the drying time of the pipe and improving the drying efficiency.

[0024] Furthermore, the cleaning pipe is provided with quick connectors at both ends.

[0025] By adopting the above technical solution, the quick connectors provided at both ends of the cleaning pipe can facilitate the connection of the cleaning pipe with the pipe to be cleaned and the first liquid outlet pipe assembly or the second liquid outlet pipe and other components. The operator does not need to use complicated tools or spend a lot of time on the connection operation, but only needs to perform simple plugging or buckling operations on the quick connector to complete the connection, thereby improving the convenience and efficiency of the operation.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: The first cleaning mechanism is combined with the second cleaning mechanism. The first cleaning mechanism uses a degreasing liquid circulation system to connect the two ends of the super-long stainless steel cold-drawn tube with two cleaning pipes, and combines the first water tank and the first liquid outlet pipe assembly to make the degreasing liquid circulate in the pipe fitting and penetrate into various positions inside the pipe fitting, overcoming the cleaning difficulties caused by the length and bending shape. The second cleaning mechanism uses a rinsing liquid to rinse the inner wall of the pipe fitting to remove the degreasing liquid and reaction products, achieve more delicate cleaning, and improve the cleaning quality of the pipe fitting; The components of the first cleaning mechanism, such as the bubble ball, the ball barrel, and the launch slot, provide a cleaning method that combines chemical degreasing with physical scrubbing. Multiple launch slots can realize efficient filling and uniform distribution of the bubble balls, and comprehensively scrub the inner wall of the pipe, which can effectively remove stubborn grease residues and make up for the shortcomings of simple chemical degreasing. By controlling the solenoid valves on the first branch pipe and the second branch pipe, forward and reverse cleaning can be achieved, further eliminating cleaning dead corners at pipe bends and rough inner wall areas, and improving the comprehensiveness and thoroughness of degreasing the inner wall of the pipe.

[0036] In the embodiment of the present application, each cleaning pipe 6 is provided with a quick connector 61 at both ends, so as to facilitate connecting the pipe 6 to be cleaned to the first cleaning mechanism 3, the second cleaning mechanism 4 or the hot air drying mechanism 5. The operator does not need to use complicated tools or spend a lot of time to perform the connection operation, but only needs to perform simple operations such as plugging or snapping the quick connector 61 to complete the connection.

[0037] Reference Figure 2 and Figure 3 The first cleaning mechanism 3 includes a first water tank 31, a first liquid outlet pipe assembly 32, a first pressure pump 33, a bubble ball 34, a ball barrel 35 and a delivery pipe 36. The first water tank 31 is arranged inside the cabinet body 1 and is used to contain the degreasing liquid. The first liquid outlet pipe assembly 32 is arranged on the upper side of the operating table 2 and is connected to the first water tank 31 through a pipeline. The first pressure pump 33 is arranged inside the cabinet body 1 and is located at an adjacent position of the first water tank 31. The first pressure pump 33 is connected between the first liquid outlet pipe assembly 32 and the first water tank 31 through a pipeline, so that the degreasing liquid in the first water tank 31 can be pumped into the first liquid outlet pipe assembly 32.

[0038] Combination Figure 4 The ball launcher 35 is disposed on the upper side of the operating table 2 and is located adjacent to the first liquid outlet pipe assembly 32 for launching the bubble ball 34. The delivery pipe 36 is used to connect the ball launcher 35 and the first liquid outlet pipe assembly 32, and the inner diameter of the delivery pipe 36 can allow the bubble ball 34 to pass through.

[0039] The ball barrel 35 has a barrel body 351 and a cover body 352. The operation table 2 is provided with a support frame 353 for mounting the barrel body 351. The cover body 352 is used to cover the barrel body 351. The delivery pipe 36 passes through the cover body 352 and communicates with the inside of the barrel body 351. The cover body 352 is provided with a bulb entrance for inserting the bulb 34. The bulb entrance is located on the side of the barrel body 351 away from the delivery pipe 36.

[0040] The barrel 351 is mounted on the upper side of the support bracket 353, and a motor 354 is provided on the lower side of the support bracket 353 for driving the barrel 351 to rotate. The barrel 351 is provided with a plurality of launch slots 3511 for placing the bulb 34 in the circumferential direction, and the upper opening of each launch slot 3511 can be aligned with the bulb 34 entrance or the delivery pipe 36 by the rotation of the barrel 351.

[0041] There are twelve launch slots 3511 in this embodiment, and multiple bulbs 34 can be placed in each launch slot 3511. The number of bulbs 34 to be placed needs to be further determined according to the length of the pipe, and then the bulbs 34 are launched at a fixed time through the control system. In this embodiment, the material of the bulb 34 is preferably a hard sponge with a certain deformation ability, so that it can fit the inner wall of the pipe and perform physical degreasing. The delivery pipe 36 is provided with a solenoid valve 7 for controlling the on-off of the pipeline. The operator can control the interval duration of the bulb 34 launch by controlling the on-off duration of the delivery pipe 36. In this embodiment, 20 bulbs 34 need to be placed in the launch slot 3511 in advance, and the launch interval of the bulb 34 is 2 minutes.

[0042] The first liquid outlet pipe assembly 32 includes a main liquid outlet pipe 321 connected to the first water tank 31, and a first branch pipe 322 and a second branch pipe 323 connected to the main liquid outlet pipe 321. Two cleaning pipes 6 are connected to the first branch pipe 322 and the second branch pipe 323 in a one-to-one correspondence. Two solenoid valves 7 for controlling the flow direction of the internal liquid are respectively provided on the first branch pipe 322 and the second branch pipe 323. Among the four solenoid valves 7, the two groups of solenoid valves 7 at the diagonal position are defined as a forward control valve group and a reverse control valve group. When the two solenoid valves 7 of the forward control valve group are opened at the same time, the degreasing liquid is controlled to circulate forward, and when the two solenoid valves 7 of the reverse control valve group are opened at the same time, the degreasing liquid is controlled to circulate reversely. In this embodiment, the one-way cycle duration needs to be set to at least 25 minutes, and then the cycle is reversed.

[0043] Reference Figure 3 and Figure 5The side wall of the cabinet body 1 is provided with a first recovery cylinder 37 for recovering the bulb 34 and the degreasing liquid above the first recovery mechanism. The first recovery cylinder 37 is connected to the first water tank 31 and the first liquid outlet pipe assembly 32 through pipelines. The first recovery cylinder 37 is provided with a filter plate 371 for intercepting the bulb 34. After the degreasing liquid and the bulb 34 are cleaned through the pipe 6, they circulate to the first liquid outlet pipe assembly 32 through the cleaning pipe 6 and then enter the first recovery cylinder 37. The bulb 34 is intercepted by the filter plate 371 in the first recovery cylinder 37 and waits for recovery by the staff. The degreasing liquid circulates back to the first water tank 31 through the pipeline and waits for the next cleaning cycle.

[0044] Reference Figure 2 and Figure 3 The second cleaning mechanism 4 includes a second water tank 41, a second pressure pump 42, a second liquid outlet pipe 43, a second recovery pipe 44 and a second recovery cylinder 45. The second water tank 41 is used to hold the rinsing liquid. The second water tank 41 is arranged inside the cabinet body 1 and adjacent to the first water tank 31.

[0045] The second liquid outlet pipe 43 is arranged on the upper side of the operating table 2 and is connected to the second water tank 41 through a pipeline. The second booster pump 42 is arranged inside the cabinet body 1 and is located adjacent to the second water tank 41. The second booster pump 42 is connected between the second liquid outlet pipe 43 and the second water tank 41 through a pipeline, so that the rinsing liquid in the second water tank 41 can be pumped into the second liquid outlet pipe 43. Figure 6 The second recovery pipe 44 is connected to the second water tank 41, and the second recovery cylinder 45 is arranged on the second recovery pipe 44 and located on the operation table 2. The second recovery cylinder 45 is provided with a filter 451 for intercepting the bulb 34.

[0046] The second liquid outlet pipe 43 and the second recovery pipe 44 both have a connection port 441. After the first cleaning mechanism 3 completes the degreasing cleaning of the pipe, the two cleaning pipes 6 are removed and connected to the connection ports 441 of the second liquid outlet pipe 43 and the second recovery pipe 44, so that the pipe and the second connection mechanism form a circulating cleaning loop. In this embodiment, the cleaning cycle of the second cleaning mechanism 4 needs to be 8-12 minutes.

[0047] A diaphragm pump 46 is provided inside the cabinet body 1 below the operating table 2 and is interconnected with the first liquid outlet pipe assembly 32 and the second recovery pipe 44 . The liquid in the pipe can be recovered into the corresponding water tank through the action of the diaphragm pump 46 .

[0048] The hot air drying mechanism 5 includes an air pump 51 and a heater 52 for heating air, which are arranged inside the cabinet body 1. The air pump 51 and the heater 52 are interconnected, and one end of the heater 52 away from the air pump 51 is interconnected with the second liquid outlet pipe 43 and the second recovery pipe 44. The air pump 51 and the heater 52 can generate high-temperature and high-pressure airflow, similar to the principle of a hair dryer, and introduce the airflow into the second liquid outlet pipe 43, and then enter the interior of the pipe to quickly evaporate the residual liquid in the pipe, shorten the drying time of the pipe, and improve the drying efficiency.

[0049] Combination Figure 1 Since the length of the extra-long stainless steel cold-drawn tube is special and can reach up to 15m, a specific frame is required to place the tube. In this embodiment, the tube is wound on a rotating frame 8, which has a base 81 and a turntable 82 rotatably connected to the top. The tube is placed on the turntable 82 and can be rotated according to demand, so as to cooperate with the degreasing device, so as to facilitate the alignment of the end of the tube with the first cleaning mechanism 3 / the second cleaning mechanism 4 / the hot air drying mechanism 5.

[0050] The implementation principle of the inner wall degreasing device of a pipe fitting in the embodiment of the present application is as follows: due to the special length of the super-long stainless steel cold-drawn pipe, it is wound on a rotating frame 8 having a base 81 and a rotating disk 82. The rotating disk 82 is rotatable, which facilitates the accurate alignment of the end of the pipe fitting with each functional mechanism of the degreasing device, and cooperates to complete a series of operations such as degreasing, rinsing and drying.

[0051] One end of the cleaning pipe 6 is connected to a pipe fitting, and the other end can be connected to the first cleaning mechanism 3, the second cleaning mechanism 4 or the hot air drying mechanism 5 according to the operation process.

[0052] In the first cleaning mechanism 3, the first water tank 31 contains the degreasing liquid, and the first pressure pump 33 pumps the degreasing liquid into the first liquid outlet pipe assembly 32. The main liquid outlet pipe 321 of the first liquid outlet pipe assembly 32 is connected to the first branch pipe 322 and the second branch pipe 323, and is respectively connected to the two cleaning pipes 6. By controlling the forward or reverse control valve group composed of the solenoid valve 7 on the first branch pipe 322 and the second branch pipe 323, the degreasing liquid is circulated forward or reversely in the pipe fitting, and the circulation time is at least 25 minutes and then the direction is reversed, ensuring that the degreasing liquid can fully flush the inner wall of the pipe fitting and remove grease.

[0053] The bulb 34 in the ball-launching barrel 35 is driven by the motor 354 to rotate the barrel 351, so that the opening of the launch slot 3511 is aligned with the entrance of the bulb 34 to load the bulb 34, and then rotates to align with the delivery pipe 36, and is fired at a fixed time under the control of the solenoid valve 7 of the delivery pipe 36. The bulb 34 flows in the pipe with the degreasing liquid to physically degrease the inner wall, making up for the deficiency of simple liquid flushing and enhancing the degreasing effect.

[0054] After cleaning, the degreasing liquid and the bulb 34 enter the first recovery cylinder 37 through the cleaning pipe 6 and the first liquid outlet pipe assembly 32, the bulb 34 is intercepted by the filter disc 371, and the degreasing liquid flows back to the first water tank 31 for recycling.

[0055] After degreasing and cleaning, first insert at least two bulbs 34 into the second liquid outlet pipe 43 of the second cleaning mechanism 4, and then connect the cleaning pipe 6 to the second liquid outlet pipe 43 and the second recovery pipe 44 to form a circulating cleaning loop. The rinsing liquid in the second water tank 41 is pumped into the second liquid outlet pipe 43 by the second booster pump 42, and together with the bulbs 34, the degreasing liquid and reaction products remaining on the inner wall of the pipe are rinsed. The second recovery cylinder 45 on the second recovery pipe 44 is used to filter the bulbs 34 for easy recovery, and the rinsed liquid is recovered to the second water tank 41 through the diaphragm pump 46 or treated accordingly. In this embodiment, the rinsing liquid is clean water. When the concentration of the rinsing liquid in the second water tank 41 exceeds the preset value, the rinsing liquid needs to be replaced.
