DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 , Figure 1 It is a three-dimensional structural schematic diagram of a tubular furnace cleaning device in a specific embodiment of the utility model; Figure 2 for Figure 1 Schematic diagram of the three-dimensional structure of the middle moving block; Figure 3 for Figure 1 Schematic diagram of the cross-sectional structure of the middle moving block; Figure 4 for Figure 1 Schematic diagram of the three-dimensional structure of the central rotation axis; Figure 5 for Figure 1 Schematic diagram of the three-dimensional structure of the middle cleaning brush mechanism.

[0024] The utility model discloses a tubular furnace cleaning device, comprising a symmetrically arranged first closed flange 1 and a second closed flange 2. When in use, the second closed flange 2 cooperates with the first closed flange 1 to form a closed structure of the quartz tube, which facilitates the travel block 5 to work by means of pressure balance. A rotating motor 3 is fixedly mounted on the right end of the first closed flange 1, and a transmission end of the left end of the rotating motor 3 passes through the first closed flange 1 and extends to the left side of the first closed flange 1. A driving screw 4 is mounted on the left side of the first closed flange 1, and the driving screw 4 is driven by the rotating motor 3.

[0025] The outer end of the driving screw 4 is threadedly connected to the traveling block 5, and the traveling block 5 is a hollow structure. A sealing ring 6 is fixedly installed on the outer end of the left part of the traveling block 5. A cleaning mechanism 7 and a leakage nozzle 8 are provided on the outer side of the traveling block 5. A connecting pipe 9 is fixedly connected between the leakage nozzle 8 and the interior of the traveling block 5, and the cleaning mechanism 7 is spirally distributed on the outer side of the traveling block 5.

[0026] A feed port 10 is provided at the left end of the traveling block 5 , a manual valve 11 is fixedly installed inside the feed port 10 , and an air inlet 12 is also provided at the left end of the traveling block 5 , a one-way valve 13 is fixedly installed inside the air inlet 12 .

[0027] The working principle of the above-mentioned tubular furnace cleaning device is as follows: when in use, the manual valve 11 is opened, and then the acetone solution is injected into the traveling block 5 from the feed port 10, and the manual valve 11 is closed; then the driving screw 4 and the traveling block 5 are inserted into the furnace tube, the first closing flange 1 is sealed and connected to one side of the furnace tube, and then the second closing flange 2 is covered on the other side of the furnace tube; the rotating motor 3 is started, and the rotating motor 3 drives the driving screw 4 to rotate, and the sealing ring 6 at the outer end of the traveling block 5 is in contact with the inner wall of the furnace tube, and there is a large friction between them. Therefore, when the driving screw 4 rotates, the traveling block 5 will automatically move forward due to the friction and the thread, and most of the dirt can be scraped off in the initial stage. After it moves, the spiral cleaning mechanism 7 on its outer side can clean the inner side of the tube wall. At the same time, when the traveling block 5 is advanced, the air pressure in the space on the left side of the furnace tube increases, and the air flow passes through the one-way valve 13 and the air inlet 12 into the cavity inside the traveling block 5. The air flow will be discharged along the connecting pipe 9 and then to the leakage nozzle 8 above that is not in contact with the solution, so that the air pressure on both sides of the traveling block 5 maintains a dynamic balance, and at the same time, the air pressure inside the traveling block 5 increases. The high air pressure can spray the solution from the leakage nozzle 8 below, and the sprayed acetone solution cooperates with the cleaning mechanism 7 to clean the inner wall of the furnace tube.

[0028] The cleaning device is suitable for cleaning the quartz tube of a tubular furnace. It adopts a moving cleaning structure that penetrates the quartz tube, and can scrape, spray and brush the dirt on the inner wall of the quartz tube. It does not require manual cleaning, saving time and effort. It cleverly uses air pressure to spray the cleaning agent, and does not require the installation of an additional power structure, thereby reducing the production cost of the device.

[0029] Furthermore, the cleaning mechanism 7 may include a sponge bar 701, which is fixedly mounted on the outer end of the traveling block 5, and a left cleaning brush 702 and a right cleaning brush 703 are also fixedly mounted on the outer end of the traveling block 5, and the two are respectively attached to the two sides of the sponge bar 701, that is, the right end of the left cleaning brush 702 is attached to the sponge bar 701, and the left end of the right cleaning brush 703 is attached to the sponge bar 701. The cleaning mechanism 7 is a spiral structure as a whole, and the spiral sponge bar 701, the left cleaning brush 702 and the right cleaning brush 703 can not only form a larger attachment surface during the rotation process along the spiral pattern, but also the spiral structure can clean the pipe wall at the maximum angle during the rotation process, thereby improving the cleaning effect.

[0030] Furthermore, the transmission end of the left end of the rotating motor 3 is fixedly connected with a rotating seat 14, the inner end of the rotating seat 14 is rotatably mounted with a rotating shaft 15, and the left end of the rotating shaft 15 is fixedly connected with the driving screw 4, so that the driving screw 4 can rotate under the drive of the rotating motor 3. When the device is not in use, the rotating seat 14 is manually adjusted, and the traveling block 5 and the driving screw 4 can be put down along the rotating seat 14 and the rotating shaft 15, reducing the floor space and facilitating storage.

[0031] In addition, a fixed base 16 may be installed below the first closed flange 1, a lifting sleeve rod 17 is fixedly installed on the upper end of the fixed base 16, a lifting rod 18 is movably installed on the upper end of the lifting sleeve rod 17, a motor seat 19 is fixedly installed on the upper end of the lifting rod 18, the upper end of the motor seat 19 is fixedly connected to the rotating motor 3, and a fixing knob 20 is threadedly connected to the outer end of the lifting sleeve rod 17. By installing the lifting sleeve rod 17 and the lifting rod 18, during use, the user can manually loosen the fixing knob 20, and then adjust the height of the lifting rod 18 and the structure above it, and tighten the fixing knob 20 after the adjustment is completed.

[0032] A universal wheel 21 may also be fixedly mounted on the lower end of the fixed base 16 , and the mounted universal wheel 21 is used for moving the device.

[0033] Compared with the prior art, the beneficial effects of the utility model are:

[0034] 1. The tubular furnace cleaning device is suitable for cleaning the quartz tube of the tubular furnace. It adopts a moving cleaning structure that penetrates the quartz tube, and can scrape, spray and brush the dirt on the inner wall of the quartz tube. It does not require manual cleaning, saving time and effort. It cleverly uses air pressure to spray the cleaning agent, and does not require the installation of an additional power structure, reducing the production cost of the device;

[0035] 2. The tubular furnace cleaning device, the spiral sponge strip, the left cleaning brush and the right cleaning brush can not only form a larger fitting surface when rotating along the spiral pattern, but also the spiral structure can clean the tube wall at the maximum angle during its rotation, thereby improving the cleaning effect;

[0036] 3. When the tubular furnace cleaning device is not in use, the rotating seat is manually adjusted. At this time, the travel block and the driving screw can be lowered along the rotating seat and the rotating axis, reducing the floor space and facilitating storage.

[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
