It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 - Figure 6As shown, this utility model provides a technical solution: an automated glass microsphere firing furnace 2, including a base 1, a firing furnace 2 disposed on the surface of the base 1, one end of the firing furnace 2 being rotatably connected to the base 1, a firing mesh cylinder 3 being horizontally disposed inside the firing furnace 2, a heating cylinder 25 being horizontally disposed inside the firing furnace 2, a gas head 26 being fixedly connected to the surface of the heating cylinder 25, a gas pipe 24 being fixedly connected to one end of the heating cylinder 25, an exhaust pipe 4 being fixedly connected to the top of the firing furnace 2, and a purification mechanism 5 being disposed on the surface of the exhaust pipe 4;

[0026] Purification mechanism 5 includes a housing 501. A square groove 502 is formed on the surface of the housing 501. A slot 503 is formed on the bottom surface of the square groove 502. A filter frame 504 is inserted inside the slot 503. An activated carbon layer 505 is placed inside the filter frame 504. A block 506 is fixedly connected to the top of the filter frame 504. A locking block 507 is slidably connected inside the block 506. A pull rod 508 is fixedly connected to the surface of the locking block 507. A push plate 510 is fixedly connected to one end of the pull rod 508. A spring 509 is sleeved on the surface of the pull rod 508. A mounting base 511 is fixedly connected to the surface of the housing 501. The locking block 507 is inserted inside the mounting base 511. A driven gear 16 is fixedly connected to the surface of one end of the firing mesh cylinder 3. The surface of the firing furnace 2... A fixed plate 14 is fixedly connected, and a motor 15 is fixedly connected to the surface of the fixed plate 14. A drive gear 17 is fixedly connected to the output end of the motor 15. The drive gear 17 meshes with the driven gear 16. An installation groove 21 is opened on the surface of the base 1. A push cylinder 22 is fixedly connected to the inclined surface of the installation groove 21. A push wheel 23 is fixedly connected to the output end of the push cylinder 22. A sealing gasket 6 is provided inside the square groove 502. The sealing gasket 6 is made of high-temperature resistant rubber. Anti-slip protrusions 27 are fixedly connected to the surface of the push plate 510. The anti-slip protrusions 27 are evenly distributed on the surface of the push plate 510. The two ends of the firing mesh cylinder 3 are respectively provided with a feeding port 19 and a discharging port 18. Both the feeding port 19 and the discharging port 18 are threadedly connected with sealing caps 20.

[0027] In this embodiment, the filter frame 504 of the purification mechanism 5 and the activated carbon layer 505 placed inside the filter frame 504 achieve the purpose of filtering and purifying the gas discharged from the flue pipe 4. This enables comprehensive and effective purification of the waste gas generated during the firing process, significantly reducing pollutants such as dust and harmful gases in the waste gas and even meeting environmental emission standards. Simultaneously, the filter frame 504 in the purification mechanism 5 cooperates with the housing 501 through components such as the locking block 507, pull rod 508, and spring 509, facilitating the removal of the filter frame 504 from the square groove 502. This allows for regular replacement or cleaning of the internal activated carbon layer 505, ensuring good filtration and purification effects. The motor 15 drives the drive gear 17 to rotate, and the drive gear 17 meshes with the driven gear 16 at one end of the firing screen cylinder 3, allowing the firing screen cylinder 3 to rotate and ensuring that all parts of the raw material are evenly distributed. The heat provided by the heating cylinder 25 prevents local overheating or uneven heating. By activating the push cylinder 22, the output end of the push cylinder 22 pushes the push wheel 2322 to move on the inclined surface of the mounting groove 21, causing one end of the firing furnace 2 to tilt up, facilitating the discharge of the fired material into the firing mesh cylinder 3. The high-temperature resistant rubber sealing gasket 6 installed in the square groove 502 effectively fills the gap between the filter mesh frame 504 and the square groove 502 after the filter mesh frame 504 is installed in place, preventing exhaust gas from leaking from these gaps and avoiding the direct discharge of unpurified exhaust gas. The anti-slip protrusions 27 evenly distributed on the surface of the push plate 510 increase the friction between the operator's hand and the push plate 510, preventing slippage when pushing the push plate 510. The sealing cap 20, which is threadedly connected to the feed port 19 and the discharge port 18, can prevent glass beads or raw materials from accidentally leaking from the port during the firing process.

[0028] Example 2: As Figure 5 As shown, the surface of the box 501 has a slot 7, the inside of the slot 7 is slidably connected to a collection box 8, the surface of the collection box 8 is fixedly connected to a fixing block 9, the inside of the fixing block 9 is slidably connected to a fixing rod 11, the surface of the box 501 is fixedly connected to a fixing seat 10, the surface of the fixing seat 10 has a fixing groove 12, the inside of the fixing groove 12 is fixedly connected to a magnet 13, one end of the fixing rod 11 is inserted into the inside of the fixing groove 12 and is magnetically connected to the magnet 13.

[0029] In this embodiment, by placing the collection box 8 in the slot 7 and inserting one end of the fixing rod 11 in the fixing block 9 into the fixing groove 12 on the fixing base 10 and magnetically attracting it with the magnet 13, impurities, dust and other waste filtered from the filter screen frame 504 can be collected for centralized processing. On the other hand, it can make the collection box 8 stable during normal use to prevent accidental slippage, and it is also convenient to easily release the fixing when the collection box 8 is full and needs to be cleaned, and pull out the collection box 8 for maintenance operations such as emptying and cleaning.

[0030] The working principle of this embodiment is as follows: First, the glass raw material is loaded into the firing mesh cylinder 3 through the feed port 19 at one end. Then, the sealing cap 20 at the feed port 19 is tightened. The sealing cap 20 effectively isolates the outside air, ensuring that a relatively independent and stable space is formed inside the firing mesh cylinder 3, creating a good initial environment for subsequent firing. Then, the gas pipe 24 delivers gas to the heating cylinder 25. The gas is burned through the gas head 26 on the surface of the heating cylinder 25, releasing heat and raising the temperature around the heating cylinder 25. This heats the firing mesh cylinder 3, which is placed horizontally inside the firing furnace 2. The glass raw material inside the firing mesh cylinder 3 gradually melts under high temperature, transforming towards the formation of glass microspheres. At the same time, the motor 15 fixed on the surface plate 14 of the firing furnace 2 starts to work. The output end of the motor 15 drives the drive gear 17 to rotate. Since the drive gear 17 meshes with the driven gear 16 fixedly connected to one end of the firing mesh cylinder 3, the firing mesh cylinder 3 starts to rotate at a uniform speed under the drive of the drive gear 17. The glass raw material inside it rolls and stirs continuously with the rotation of the mesh cylinder, so that all parts of the raw material can receive heat from the heating cylinder 25 evenly. This ensures that the glass raw material is heated evenly as a whole, which helps to improve the quality of the fired products and avoids defects caused by uneven heating in some areas. The exhaust gas generated during the firing process will drift upward and enter the purification mechanism 5 through the exhaust pipe 4 fixedly connected to the top of the firing furnace 2. The exhaust gas first enters the housing 501 of the purification mechanism 5, and then passes through the filter frame 504 inserted into the slot 503 at the bottom of the square groove 502 of the housing 501. The activated carbon layer 505 inside the filter frame 504 adsorbs and filters harmful components in the exhaust gas, such as odors and some harmful gases, thus purifying the exhaust gas. The high-temperature resistant rubber sealing gasket 6 inside the square groove 502 can tightly fit the filter frame 504 to prevent exhaust gas from leaking from the gaps, ensuring that the exhaust gas can fully pass through the activated carbon layer 505 for purification and guaranteeing the purification effect. After firing, the push cylinder 22 is fixedly connected to the inclined surface of the mounting groove 21 on the surface of the base 1. When the machine starts working, the output end of the push cylinder 22 pushes the push wheel 23. The push wheel 23 acts on the firing furnace 2. Since one end of the firing furnace 2 is rotatably connected to the base 1, the firing furnace 2 will rotate around the rotatable connection point under the push of the push wheel 23. This makes the discharge port 18 of the firing screen cylinder 3 in a suitable tilt position, so that the fired glass microspheres can be smoothly discharged from the discharge port 18 under the action of gravity. When discharging, simply unscrew the sealing cap 20 of the discharge port 18. As the usage time increases, the activated carbon layer 505 in the filter screen frame 504 will adsorb more impurities, which will affect the purification effect. At this time, it is necessary to clean or replace it.The operator grips the push plate 510. The evenly distributed anti-slip protrusions 27 on the surface of the push plate 510 increase the friction of the hand, making it easier to apply force. Pulling the push plate 510 moves the pull rod 508 outward. The pull rod 508 causes the locking block 507 to disengage from the locking seat 511 on the surface of the housing 501, while simultaneously compressing the spring 509. Then, the filter screen frame 504 can be removed upward for corresponding maintenance operations. During the purification process, after the exhaust gas is purified by the filter screen frame 504, the intercepted impurities fall into the collection box 8, which is slidably connected in the slot 7 on the surface of the housing 501. In the process, the collection box 8 is inserted into the fixing groove 12 on the fixing seat 10 on the surface of the box body 501 via the fixing rod 11 slidably connected inside the fixing block 9. It is magnetically connected to the magnet 13 fixed inside the fixing groove 12 to achieve stable fixation. When it is necessary to clean the collection box 8, simply pull out the fixing rod 11 to release the magnetic connection, and the collection box 8 can be pulled out of the slot 7, the impurities collected inside can be poured out, and then the collection box 8 can be installed back in its original position. This facilitates the centralized treatment of impurities generated during the purification process and ensures that the purification mechanism can continue to operate normally.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
