Technical Field

[0001] This utility model relates to the field of heat treatment engineering machinery technology, specifically to a furnace tube inner wall cleaning device. Background Technology

[0002] When cleaning furnace tubes, the furnace tube cleaning machine needs to soak the furnace tubes in a chemical solution, and then rinse, soak, and overflow the furnace tubes with water. This mainly removes residual chemical solution, particles, and other substances. Due to the limitations of the tank structure, the furnace tube cleaning machine can only rinse the outer surface of the furnace tubes with water, and cannot rinse the inner wall of the furnace tubes with water. When there are particles on the inner wall of the furnace tubes, it is difficult to remove them by soaking and draining. Residual chemical solution also requires a large amount of water to soak, dilute, and remove. Utility Model Content

[0003] In view of this, the present invention provides a furnace tube inner wall cleaning device to solve the problem that furnace tube cleaning machines can only rinse the outer surface of the furnace tube with water, but cannot rinse the inner wall of the furnace tube with water.

[0012] In one optional embodiment, the gear set includes at least three gears, which are disposed on the side wall of the cleaning tank and mesh with each other vertically. The lowermost gear is driven by the support rod, and the motor is driven by the uppermost gear.

[0013] Beneficial effect: By setting at least three gears to mesh vertically, the distance between the motor and the support rod is increased, thereby preventing the water level in the cleaning tank from being too high and flowing into the motor, which would damage the motor.

[0014] In one optional embodiment, the cleaning assembly includes a water supply pipeline, a first valve body, and a cleaning pipeline. A first end of the water supply pipeline is adapted to be connected to the water source, and a second end of the water supply pipeline is connected to the first end of the cleaning pipeline.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0031] According to the embodiment of the present utility model, Figures 1 to 3 As shown, a furnace tube 7 inner wall cleaning device is provided, including: a cleaning base 1, a support assembly 2, a cleaning assembly 3, a drainage assembly 4, and a drive assembly 5. The cleaning base 1 has a cleaning tank 101 extending through the top of the cleaning base 1 to form an installation opening. The support assembly 2 is disposed within the cleaning tank 101 and near the bottom of the cleaning base 1, and is adapted to support the furnace tube 7 and rotatably abut against it. The cleaning assembly 3 is detachably connected to the cleaning base 1. A first end of the cleaning assembly 3 is adapted to be connected to a water source, and a second end of the cleaning assembly 3 penetrates the side wall of the cleaning base 1 and is inserted into the cleaning tank 101, with at least a portion of the cleaning assembly 3 adapted to be inserted into the furnace tube 7. The drainage assembly 4 is adapted to drain accumulated water from the cleaning tank 101. The drive assembly 5 is adapted to drive the support assembly 2 to rotate.

[0032] By placing the furnace tube 7 from the installation port onto the support component 2 inside the cleaning tank 101, and simultaneously inserting the cleaning component 3 into the furnace tube 7, the furnace tube 7 rotates when the drive component 5 drives the support component 2 to rotate. At the same time, the cleaning component 3 sprays high-pressure liquid into the furnace tube 7 to clean the particulate matter on the inner wall of the furnace tube 7. The water added to the cleaning tank 101 also soaks the inner wall of the rotating furnace tube 7, thus thoroughly and effectively cleaning the inner wall of the furnace tube 7.

[0033] In one embodiment, such as Figure 1 and Figure 3 As shown, the support assembly 2 includes support rods 201 and support wheels 202. Support wheels 202 are mounted on the support rods 201. At least two support rods 201 are spaced apart, and several support wheels 202 are provided. Each support rod 201 has several support wheels 202. The support wheels 202 are adapted to rotatably abut against the furnace tube 7. One support rod 201 is connected to the drive assembly 5, and the two ends of the remaining support rods 201 are rotatably connected to the sidewall of the cleaning base 1. By setting the support rods 201 and support wheels 202, the furnace tube 7 is stably supported, preventing it from shaking and falling during the cleaning process, thus avoiding damage to the outer wall surface of the furnace tube 7.

[0034] Specifically, a rotating shaft is provided inside the side wall of the cleaning base 1, and the support rod 201 is rotatably connected to the side wall of the cleaning base 1 through the rotating shaft.

[0035] In one embodiment, an elastic element is provided on the outer peripheral surface of the support wheel 202. By providing the elastic element, the contact position between the support wheel 202 and the furnace tube 7 is protected, preventing the support wheel 202 from damaging the outer wall of the furnace tube 7.

[0036] Specifically, the elastic element can be a component with good elasticity and plasticity, such as rubber or polyurethane, which is beneficial to increase the friction between the support wheel 202 and the furnace tube 7, and is less likely to damage the outer wall of the furnace tube 7.

[0037] In one embodiment, such as Figure 1 and Figure 3 As shown, the drive assembly 5 includes a motor 501 and a gear set 502. The output end of the motor 501 is connected to the gear set 502, and the gear set 502 is connected to a support rod 201 to allow the furnace tube 7 to be rotatably mounted. The furnace tube 7 is also connected to the remaining support rod 201 to allow the remaining support rod 201 to rotate. By using the motor 501 and gear set 502 to drive the support rod 201, the overall structure is simple, the transmission efficiency is high, and the working efficiency of the furnace tube 7 inner wall cleaning device is improved.

[0038] In one embodiment, such as Figure 1As shown, the gear set 502 includes at least three gears, which are arranged vertically and mesh with each other on the side wall of the cleaning tank 101. The lowermost gear is connected to the support rod 201, and the motor 501 is connected to the uppermost gear. By arranging at least three gears to mesh vertically, the distance between the motor 501 and the support rod 201 is increased, thereby preventing excessive water level in the cleaning tank 101 from flowing into the motor 501 and damaging it.

[0039] Specifically, in this embodiment, such as Figure 1 As shown, the gear set 502 is set on the side wall of the cleaning tank 101, and the output end of the motor 501 passes through the side wall of the cleaning tank 101. If the position of the motor 501 is lower than the water level in the cleaning tank 101, the water in the cleaning tank 101 will seep into the motor 501 through the position where the motor 501 passes through the side wall, causing damage to the motor 501.

[0040] It should be noted that, compared with the prior art which requires a large amount of water to soak the furnace tube 7, this application uses the support component 2 to rotate the furnace tube 7, thus eliminating the need for a large amount of water to soak it. Only a portion of the furnace tube 7 needs to be submerged, and the furnace tube 7 is cleaned by rotating it. However, the impact of water accumulation on the motor 501 still needs to be considered. Therefore, in this embodiment, the stroke of the gear set 502 is increased by setting at least three gears, thereby further avoiding damage caused by water entering the motor 501.

[0041] In one embodiment, such as Figure 1 and Figure 2 As shown, the cleaning assembly 3 includes a water supply pipe 301, a first valve body 302, and a cleaning pipe 303. The first end of the water supply pipe 301 is adapted to connect to a water source, and the second end of the water supply pipe 301 is connected to the first end of the cleaning pipe 303. The second end of the cleaning pipe 303 is adapted to be inserted into the furnace tube 7. The cleaning pipe 303 has several water outlets spaced apart along its extension direction. The first valve body 302 is installed on the water supply pipe 301 to control its on / off state. By controlling the on / off state of the water supply pipe 301 with the first valve body 302, the start / stop control of the cleaning of the inner wall of the furnace tube 7 is achieved, avoiding water waste. The multiple water outlets ensure thorough cleaning of the inner wall of the furnace tube 7, preventing particulate matter and chemical residue from remaining on the cleaned inner wall.

[0042] Specifically, in this embodiment, the cleaning pipeline 303 is a Teflon tube, which has good corrosion resistance, long service life, and low maintenance cost.

[0043] Specifically, in this embodiment, such as Figure 3As shown, the cleaning pipe 303 is provided with threads, and the side wall of the cleaning base 1 is provided with threaded holes. The cleaning pipe 303 passes through the side wall of the cleaning base 1 and is threadedly connected to the cleaning base 1 to realize the disassembly and installation of the cleaning pipe 303 and the cleaning base 1.

[0044] Specifically, the water outlets are not only spaced along the extension direction of the cleaning pipe 303, but also spaced around the circumference of the cleaning pipe 303. By setting several water outlets in different positions, the inner wall of the furnace tube 7 is further thoroughly rinsed, thereby improving the cleaning quality of the inner wall of the furnace tube 7.

[0045] In one embodiment, such as Figures 1 to 3 As shown, the furnace tube 7 inner wall cleaning device also includes a drying component 6, which is connected to the cleaning pipeline 303. By setting the drying component 6, the residual moisture can be quickly dried after the furnace tube 7 inner wall is cleaned, so that the furnace tube 7 can be put into use immediately, thus improving the utilization efficiency of the furnace tube 7.

[0046] In one embodiment, such as Figures 1 to 3 As shown, the drying assembly 6 includes a gas supply line 601 and a heating wire 602. The first end of the gas supply line 601 is adapted to be connected to a nitrogen generator, and the second end of the gas supply line 601 is connected to a cleaning line 303. The heating wire 602 is wound around the outer periphery of the gas supply line 601.

[0047] Specifically, in this embodiment, such as Figure 2 As shown, the gas supply line 601, the cleaning line 303, and the water supply line 301 are connected by a T-connector. When cleaning is required, the third valve body 603 is closed, the first valve body 302 is opened, and high-pressure water is sprayed from the water outlet to clean the inner wall of the furnace tube 7. After cleaning, the first valve body 302 is closed, the third valve body 603 is opened, and heated nitrogen is introduced. The nitrogen is also sprayed from the water outlet to dry the inner wall of the furnace tube 7.

[0048] In one embodiment, such as Figures 1 to 3 As shown, a third valve body 603 is also provided on the gas supply line 601 to control the on / off state of the gas supply line 601. The third valve body 603 is located downstream of the heating wire 602. By providing the third valve body 603, the on / off state of nitrogen gas is controlled, thereby avoiding the waste of gas when drying is not required and improving the operability of the furnace tube 7 inner wall cleaning device.

[0049] It should be noted that heated nitrogen has low humidity, which can effectively reduce the humidity in the drying environment; during the nitrogen drying process, oxygen can be removed from the drying environment, thereby reducing the oxidation reaction on the inner wall surface of the furnace tube 7; nitrogen molecules are large and have low mobility, so during the nitrogen drying process, there is a lack of effective chemical reaction between nitrogen and water molecules on the inner wall surface of the furnace tube 7. Therefore, compared with the traditional hot air drying method, nitrogen drying can evaporate the moisture on the inner wall of the furnace tube 7 more quickly.

[0050] In one embodiment, such as Figures 1 to 3 As shown, the drainage assembly 4 includes a drainage pipe 401 and a second valve body 402. The first end of the drainage pipe 401 penetrates the bottom surface of the cleaning base 1 and is connected to the cleaning tank 101. The second end of the drainage pipe 401 extends to the outside of the cleaning base 1. The second valve body 402 is installed on the drainage pipe 401 to control the opening and closing of the drainage pipe 401. By setting up the drainage pipe 401, the water accumulated in the cleaning tank 101 can be quickly drained after the furnace tube 7 is cleaned, avoiding damage caused by prolonged soaking of the furnace tube 7 due to prolonged water accumulation. By setting up the second valve body 402, when the furnace tube 7 needs to be soaked, there is soaking water in the cleaning tank 101. After the furnace tube 7 is cleaned, the water can be quickly drained, improving the operability of the furnace tube 7 inner wall cleaning device.

[0051] When using the furnace tube 7 inner wall cleaning device of this embodiment, firstly, the furnace tube 7 is placed from the installation port onto the support assembly 2 inside the cleaning tank 101; then, the cleaning assembly 3 is inserted into the furnace tube 7; next, the motor 501 is started, the motor 501 drives one support rod 201 to rotate, the support wheel 202 on the support rod 201 drives the furnace tube 7 to rotate, and the rotation of the furnace tube 7 drives the remaining support wheel 202 and support rod 201 to rotate; at the same time, an appropriate amount of water is added to the cleaning tank 101 to soak the furnace tube 7. Simultaneously, the first valve body 302 is opened, water is introduced into the cleaning pipe 303, and high-pressure water is sprayed out from the outlet to rinse the inner wall of the furnace tube 7. After rinsing, the motor 501 and the first valve body 302 are turned off, the second valve body 402 is opened to drain the water in the cleaning tank 101 from the drain pipe 401, and the third valve body 603 is opened to introduce heated nitrogen into the furnace tube 7 to dry the inner wall of the furnace tube 7. Finally, the cleaning assembly 3 is taken out of the furnace tube 7, and the cleaned furnace tube 7 is lifted out from the installation port for continued use.

[0052] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
