Description

Technical Field

[0001] This utility model relates to the field of industrial furnace tube technology, and in particular to an environmentally friendly industrial furnace tube cleaning device. Background Technology

[0002] Furnace tubes are widely used in various industrial production processes and are an indispensable production component. However, during production and use, furnace tubes will develop some problems such as surface contamination and stress accumulation, so they usually need to be cleaned.

[0003] In existing furnace tube cleaning equipment, such as the "furnace tube cleaning mechanism" disclosed in authorization announcement number CN 208178032U, the furnace tube is placed on a furnace tube drive roller, causing the furnace tube to rotate together with the drive roller. The cleaning agent is injected from the flared slot through the agent addition pipes on both sides, immersing the furnace tube in the cleaning agent to clean its inner and outer walls simultaneously. However, during immersion cleaning, the furnace tube is immersed in the cleaning solution for a long time, which not only consumes a large amount of cleaning agent but also results in low cleaning efficiency and a long cleaning cycle. It can also cause unnecessary corrosion to the outer wall of the furnace tube. When cleaning the inside of the furnace tube, the lack of a real-time monitoring mechanism makes it difficult for operators to understand the cleaning progress and effect of the furnace tube in a timely manner, and makes it impossible to detect uncleaned areas and defects inside the furnace tube. This makes it difficult to guarantee the cleaning quality and may require multiple rework cleanings, thus increasing costs and time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly industrial furnace tube cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An environmentally friendly industrial furnace tube cleaning device includes a support frame, an inner cleaning tank fixedly connected inside the support frame, an electric hydraulic rod provided on one side of the inner wall of the inner cleaning tank, a telescopic arm connected to the output end of the electric hydraulic rod, and a support base fixedly connected to the end of the telescopic arm.

[0007] The support base has a groove on the side away from the telescopic arm, and a drive motor is installed in the groove. The output end of the drive motor is connected to a cleaning nozzle. The cleaning nozzle has several direct-shot holes on the side away from the drive motor. An oblique-shot nozzle is fixedly connected to the side wall of the cleaning nozzle. Both the direct-shot holes and the oblique-shot nozzle are connected to the interior of the cleaning nozzle.

[0008] Preferably, a vibration motor is provided on one side of the top of the inner cleaning tank, the output end of the vibration motor is connected to a drive rod, one end of the drive rod is connected to a connecting block through a connecting rod, a sliding rod is fixedly connected to one side of the connecting block, and a cleaning connecting frame is fixedly connected between the sliding rods.

[0009] Preferably, the bottom of the cleaning connecting frame is provided with lower vibrating plates at equal intervals, and an upper vibrating plate is provided above the lower vibrating plates. Both the lower and upper vibrating plates have an arc-shaped groove on one side for placing the furnace tube. The outer walls of both the lower and upper vibrating plates have positioning holes, and positioning rods are provided in the positioning holes.

[0010] Preferably, an endoscope is provided on the top of the support base, and a connecting wire is connected to the connecting end of the endoscope. The connecting wire passes through the cleaning inner tank and extends to the outside of the support frame and is electrically connected to an electrical control box. The outer wall of the electrical control box is provided with a display screen and several control switches.

[0011] Preferably, a cleaning liquid tank is provided on the outside of the support frame, and a delivery pipe is connected to the outlet end of the cleaning liquid tank. One end of the delivery pipe extends into the interior of the cleaning tank and is connected to the cleaning nozzle, forming a flow channel with the direct spray hole and the oblique spray pipe.

[0012] Preferably, a water pump and a flow regulating valve are installed at one end of the delivery pipeline near the cleaning liquid tank, a pressure sensor is installed at the other end of the delivery pipeline near the cleaning nozzle, and a water injection pipe is connected to one end of the cleaning liquid tank, with one end of the water injection pipe extending to the bottom of the inner cleaning tank.

[0013] Preferably, wheel seats are fixedly connected to the top two sides of the inner cleaning tank, and a support wheel is movably connected to the inside of the wheel seat through a connecting shaft. A movable groove is opened in the middle of the support wheel, and the slide rod is placed in the movable groove and movably connected to the support wheel.

[0014] Preferably, a drain pipe is provided at the bottom of the inner cleaning tank, the end of the drain pipe is connected to the inside of the inner cleaning tank, and a sealing plug is provided at the end of the drain pipe away from the inner cleaning tank.

[0015] The beneficial effects of this utility model are:

[0016] The telescopic arm and cleaning nozzle are driven by an electric hydraulic rod to extend into the furnace tube. Combining the direct spray hole, the oblique spray pipe, and the nozzle rotation function, the inner wall of the furnace tube is cleaned from multiple angles and all directions. Compared with the traditional soaking cleaning method, it can remove dirt more accurately and efficiently, significantly improve the cleaning effect, reduce cleaning time, and avoid multiple rework cleanings. While cleaning the inner wall of the furnace tube, the vibration motor drives the cleaning connecting frame to vibrate, so that the furnace tube vibrates synchronously, effectively weakening the adhesion of dirt on the surface of the furnace tube. Combined with the flushing of the cleaning fluid, the cleaning efficiency is further improved, and the inner and outer walls of the furnace tube are cleaned at the same time, making the cleaning more comprehensive.

[0017] During the furnace tube cleaning process, by equipping the delivery pipeline with a flow regulating valve and a pressure sensor, the flow rate and pressure of the cleaning fluid can be precisely adjusted according to the degree of fouling of the furnace tube and the cleaning stage. This ensures the cleaning effect, prevents damage to the furnace tube due to improper pressure, and reduces cleaning fluid waste and chemical consumption.

[0018] The built-in endoscope monitors the cleaning process inside the furnace tubes in real time and transmits the images to the display screen of the electrical control box. This allows operators to intuitively understand the cleaning progress and effect, promptly identify uncleaned areas and furnace tube defects, ensure cleaning quality, and reduce costs and cleaning time.

[0029] Example:

[0030] Reference Figures 1-5 An environmentally friendly industrial furnace tube cleaning device includes a support frame 1, a cleaning inner tank 2 fixedly connected inside the support frame 1, an electric hydraulic rod 3 provided on one side of the inner wall of the cleaning inner tank 2, a telescopic arm 301 connected to the output end of the electric hydraulic rod 3, and a support seat 302 fixedly connected to the end of the telescopic arm 301.

[0031] The support base 302 has a groove on the side away from the telescopic arm 301. A drive motor 303 is installed in the groove. The output end of the drive motor 303 is connected to a cleaning nozzle 4. The cleaning nozzle 4 has several direct-shot holes 401 on the side away from the drive motor 303. An oblique-shot nozzle 402 is fixedly connected to the side wall of the cleaning nozzle 4. Both the direct-shot holes 401 and the oblique-shot nozzle 402 are connected to the interior of the cleaning nozzle 4.

[0032] A vibration motor 5 is installed on one side of the top of the inner cleaning tank 2. The output end of the vibration motor 5 is connected to a drive rod 501. One end of the drive rod 501 is connected to a connecting block 503 through a connecting rod 502. A sliding rod 504 is fixedly connected to one side of the connecting block 503. A cleaning connecting frame 6 is fixedly connected between the sliding rods 504.

[0033] The bottom of the cleaning connecting frame 6 is provided with lower vibrating plates 601 at equal intervals, and an upper vibrating plate 602 is provided above the lower vibrating plate 601. Both the lower vibrating plate 601 and the upper vibrating plate 602 have arc-shaped grooves 603 on one side for placing furnace tubes. Both the lower vibrating plate 601 and the upper vibrating plate 602 have positioning holes on their outer walls, and positioning rods 604 are provided in the positioning holes.

[0034] An endoscope 7 is installed on the top of the support base 302. The endoscope 7 is connected to a connecting wire 701. The connecting wire 701 passes through the cleaning inner tank 2 and extends to the outside of the support frame 1 and is electrically connected to an electrical control box 702. The outer wall of the electrical control box 702 is equipped with a display screen and several control switches.

[0035] A cleaning liquid tank 8 is provided on the outside of the support frame 1. The outlet end of the cleaning liquid tank 8 is connected to a conveying pipe 801. One end of the conveying pipe 801 extends into the interior of the cleaning inner tank 2 and is connected to the cleaning nozzle 4, forming a flow channel with the direct injection hole 401 and the oblique injection pipe 402.

[0036] A water pump and a flow regulating valve 802 are installed at one end of the delivery pipe 801 near the cleaning fluid tank 8. A pressure sensor 803 is installed at one end of the delivery pipe 801 near the cleaning nozzle 4. A water injection pipe 804 is connected to one end of the cleaning fluid tank 8, and one end of the water injection pipe 804 extends to the bottom of the inner cleaning tank 2.

[0037] Wheel seats 9 are fixedly connected to the top two sides of the inner cleaning tank 2. A support wheel 901 is movably connected to the inside of the wheel seat 9 through a connecting shaft. A movable groove is opened in the middle of the support wheel 901. The slide rod 504 is placed in the movable groove and is movably connected to the support wheel 901.

[0038] A drain pipe 10 is provided at the bottom of the inner cleaning tank 2. The end of the drain pipe 10 is connected to the inside of the inner cleaning tank 2. A sealing plug is provided at the end of the drain pipe 10 away from the inner cleaning tank 2.

[0039] In this embodiment, when the furnace tube needs to be cleaned, it is first placed in the arc-shaped groove 603 of the lower vibrating plate 601 and the upper vibrating plate 602. Then, the positioning rod 604 is inserted into the positioning hole of the lower vibrating plate 601 and the upper vibrating plate 602 to fix the position of the furnace tube and prevent it from shifting during the subsequent cleaning process. After the furnace tube is fixed, the electric hydraulic rod 3 is activated. When the electric hydraulic rod 3 is running, it drives the telescopic arm 301 to move into the interior of the furnace tube. When the telescopic arm 301 moves, it drives the support base 302 and the cleaning nozzle 4 to enter the interior of the furnace tube and move along the path of the inner wall of the furnace tube. At this time, the water pump is activated so that the cleaning liquid in the cleaning liquid tank 8 flows through the delivery pipe 801 to the cleaning nozzle 4. Then, the cleaning liquid flows from the flow channel and is sprayed out through the direct injection hole 401 and the oblique injection nozzle 402. The cleaning liquid flows out from the direct injection hole 401. When the cleaning nozzle 4 is sprayed, it is used to directly flush the inner wall of the furnace tube to remove larger dirt. The cleaning fluid is sprayed from the angled spray nozzle 402, which allows the cleaning fluid to impact the inner wall of the furnace tube at a certain angle, enhancing the cleaning coverage and cleaning effect. While the cleaning nozzle 4 is cleaning the furnace tube, the drive motor 303 is started. When the drive motor 303 is running, it drives the cleaning nozzle 4 to rotate while cleaning, ensuring that the cleaning fluid can be evenly sprayed on the inner wall of the furnace tube, ensuring that the entire inner wall is thoroughly cleaned, and improving the cleaning effect of the furnace tube. When the delivery pipe 801 delivers the cleaning fluid to the cleaning nozzle 4, the flow regulating valve 802 can adjust the spray volume of the cleaning fluid in a timely manner according to the degree of dirt on the furnace tube and the cleaning stage. The pressure sensor 803 is used to monitor the pressure inside the furnace tube in real time to ensure that the cleaning fluid is delivered under appropriate pressure, ensuring the cleaning effect while avoiding damage to the furnace tube.

[0040] Furthermore, when the electric hydraulic rod 3 drives the telescopic arm 301 to move along the inside of the furnace tube, the telescopic arm 301 moves simultaneously, causing the endoscope 7 to move inside the furnace tube. When the endoscope 7 moves inside the furnace tube, it can observe and detect the cleaning status inside the furnace tube in real time, and transmit the image to the display screen of the electrical control box 702 through the connecting cable 701. This allows the operator to intuitively observe the cleaning progress and cleaning effect through the display screen, and promptly identify areas that have not been cleaned or defects inside the furnace tube, so as to adjust the working status of the cleaning nozzle 4.

[0041] Furthermore, while cleaning the inner wall of the furnace tube, cleaning fluid is injected into the cleaning tank 2 through the water injection pipe 804. Then, the vibration motor 5 is started. When the vibration motor 5 is running, the eccentric block inside it generates centrifugal force when rotating at high speed. The centrifugal force causes the vibration motor 5 to vibrate. The vibration of the vibration motor 5 then drives the drive rod 501 to move. When the drive rod 501 moves, it drives the connecting rod 502 to reciprocate around the connection point between the connecting rod 502 and the drive rod 501. Then, when the connecting rod 502 moves, it transmits the motion to the slide rod 504 through the connecting block 503. When the slide rod 504 reciprocates along the support wheel 901, it drives the cleaning connecting frame 6 to move as well, thereby generating vibration. When the cleaning connecting frame 6 vibrates, it causes the lower vibrating plate 601 and the upper vibrating plate 602 within it to vibrate. As a result, the vibration of the lower vibrating plate 601 and the upper vibrating plate 602 causes the furnace tube within it to vibrate. Thus, while cleaning the outer surface of the furnace tube, the vibration of the furnace tube weakens the adhesion between the dirt on the surface of the furnace tube and the furnace tube. For some dust and loose deposits with relatively weak adhesion, they gradually fall off from the surface of the furnace tube. The dirt that is peeled off and washed off is carried away with the flow of cleaning fluid. At this time, the sealing plug at the bottom of the drain pipe 10 is removed, so that the cleaning fluid carrying the dirt is discharged from the drain pipe 10 into the cleaning inner tank 2, completing the cleaning process of the furnace tube.
