Description

Technical Field

[0001] This utility model relates to the technical field of heating furnace equipment, specifically an easy-to-clean heating furnace. Background Technology

[0002] A heating furnace is a device used to heat substances (usually liquids, gases, or solids) to a specific temperature. These devices are widely used in various industrial processes, such as petrochemicals, steel smelting, food processing, and ceramics production.

[0003] After a period of use, heating furnaces accumulate dust, which is pushed onto the inner wall of the furnace. If not cleaned in time, the dust is difficult to scrape off easily. Here we propose an easy-to-clean heating furnace that can use combustion air to drive a cleaning device to clean the movable inner wall and make it easy to remove the movable inner wall for deep cleaning.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: an easy-to-clean heating furnace, including a heating furnace 1 and a top plate 2. Six sets of mounting rails 4 are fixedly welded to the inner wall of the heating furnace 1. Lifting rods 5 are fixedly welded inside the mounting rails 4. Two sets of lugs 6 are slidably installed on the outer side of the lifting rods 5. A movable inner wall 7 is fixedly welded to one side of the lugs 6. A lifting point 13 is provided on the upper part of the movable inner wall 7. The movable inner wall 7 is made of heat-insulating material. By sliding along the lugs 6 of the lifting rods 5, the movable inner wall 7 can be moved out along the upper part of the heating furnace 1 via the lifting point 13, facilitating the cleaning of dust on the inner side of the movable inner wall 7. A gas outlet pipe 3 is fixedly welded to the middle of the upper side of the top plate 2. After combustion... Hot air is discharged from the heating furnace 1 through the exhaust pipe 3. An installation plate 17 is fixedly welded inside the exhaust pipe 3. A rotating shaft 18 is rotatably installed inside the installation plate 17. A fan blade 19 is fixedly welded to the upper part of the rotating shaft 18. A connecting plate 20 is fixedly welded to the lower part of the rotating shaft 18. Rotating rods 21 are rotatably installed inside both sides of the connecting plate 20. Several sets of scrapers 22 are fixedly welded to the outer side of the rotating rods 21. The scrapers 22 are made of rubber. After the hot air is discharged from the exhaust pipe 3, it drives the fan blade 19 and the rotating shaft 18 to rotate. The rotation of the connecting plate 20 causes the scrapers 22 to scrape off the dust on the inner side of the movable inner wall 7 through the rotating rods 21, thereby reducing the accumulation of dust.

[0025] A lower limit ring 23 is fixedly welded to the lower side of the heating furnace 1, which is directly opposite the rotating rod 21, to prevent the rotating rod 21 from shaking under airflow and affecting its service life. An internal gear ring 24 is fixedly welded to the inner side of the lower limit ring 23, and a connecting gear 25 that matches the internal gear ring 24 is fixedly welded to the lower part of the rotating rod 21. When the connecting plate 20 rotates, the internal gear ring 24 drives the connecting gear 25 to rotate, thereby causing the rotating rod 21 to rotate itself, so that the scraper 22 can continuously scrape off the dust on the inner side of the movable inner wall 7.

[0026] The lower part of the top plate 2 is fixedly welded with an upper limit ring 14 facing the movable inner wall 7. After the top plate 2 is installed, the movable inner wall 7 is embedded in the upper limit ring 14 to further prevent the movable inner wall 7 from shaking under air flow. The lower part of the top plate 2 is fixedly welded with six sets of blocking blocks 15 facing the mounting rail 4. The lower part of the blocking blocks 15 is fixedly welded with a positioning cylinder 16 that cooperates with the lifting rod 5. When the top plate 2 is installed, the blocking blocks 15 are inserted into the mounting rail 4, and the upper part of the lifting rod 5 is inserted into the positioning cylinder 16, thereby limiting the upper part of the lifting rod 5 and ensuring the stability of the structure.

[0027] A rubber sheet 8 is fixedly welded to one side of the movable inner wall 7, and an embedding groove 9 that matches the rubber sheet 8 is opened on the other side of the movable inner wall 7. When the movable inner wall 7 is installed around the heating furnace 1, the rubber sheet 8 is inserted into the embedding groove 9 to ensure the sealing between the movable inner walls 7 and prevent dust from contacting the inner wall of the heating furnace 1 through the movable inner wall 7.

[0028] A pressure plate 10 is slidably installed inside the embedded groove 9. A threaded rod 11 is rotatably installed on the upper outer side of the pressure plate 10. The threaded rod 11 is threadedly installed inside the movable inner wall 7. A sliding rod 12 is fixedly welded to the lower outer side of the pressure plate 10. The sliding rod 12 is slidably installed inside the movable inner wall 7. By rotating the threaded rod 11, the pressure plate 10 is driven to cooperate with the inner wall of the embedded groove 9 to press the rubber sheet 8, thereby preventing the rubber sheet 8 from falling out of the embedded groove 9 under the blowing of air.

[0029] The mounting plate 17 and the connecting plate 20 have internal communication grooves 26 on both sides, allowing air to flow upwards through the communication grooves 26, thus preventing the mounting plate 17 and the connecting plate 20 from affecting airflow.

[0030] A combustion chamber 27 is provided inside the lower side of the heating furnace 1. An isolation plate 28 is fixedly welded to the middle of the combustion chamber 27. A connecting frame 29 is fixedly welded to the upper part of the isolation plate 28. A connecting pipe 30 is fixedly welded to the outside of the connecting frame 29 to support the flow pipe 30 and prevent the structure of the flow pipe 30 from being unstable. Connecting pipes 31 are fixedly welded to both sides of the lower part of the flow pipe 30. The connecting pipes 31 extend to the outside of the heating furnace 1. The liquid to be heated enters the flow pipe 30 through one connecting pipe 31 and then flows out through the other connecting pipe 31. The combustion chamber 27 heats the liquid in the flow pipe 30 by causing the hot air to move upward.

[0031] Flanges 33 are fixedly welded to the outside of the heating furnace 1 and the top plate 2 facing each other on one side, which facilitates the installation and disassembly of the top plate 2 and the heating furnace 1.

[0032] Control doors 32 are provided on both sides of the upper part of the top plate 2. By opening the control doors 32, it is convenient to control the rotating rod 21 so that when the connecting gear 25 at the lower part of the rotating rod 21 is inserted into the internal gear ring 24, it can smoothly mesh with the internal gear ring 24.

[0033] Working principle: The liquid to be heated enters the flow pipe 30 through the connecting pipe 31 on one side and then flows out through the connecting pipe 31 on the other side. The combustion chamber 27 heats the hot air, causing it to move upward and thus heating the liquid in the flow pipe 30. The hot air is discharged through the exhaust pipe 3 and drives the fan blade 19 and the rotating shaft 18 to rotate. The connecting plate 20 rotates, causing the rotating rod 21 to rotate around the rotating shaft 18. The internal gear ring 24 drives the connecting gear 25 to rotate, thereby causing the rotating rod 21 to rotate itself. This allows the scraper 22 to continuously scrape off the dust on the inner side of the movable inner wall 7. After the heating furnace 1 has been used for a long time, the top plate 2 can be opened through the flange 33, and the movable inner wall 7 can be moved out along the upper part of the heating furnace 1 by sliding the lug 6 along the lifting rod 5, making it convenient to clean the dust on the inner side of the movable inner wall 7.
