Description

Technical Field

[0001] This utility model relates to the field of quartz stone production and processing technology, specifically to a drying oven for quartz stone production. Background Technology

[0002] Quartz stone is an artificial stone made of materials such as quartz crystals and resin. The raw materials of quartz stone usually contain a certain amount of moisture, which can be removed by drying. This process also promotes better curing and cross-linking of the resin and other binders in the quartz stone, enhancing the internal bonding force and thus improving its overall strength and hardness.

[0003] However, during the drying process of quartz stone, the dust adhering to its surface will gradually dry under continuous drying and is easy to float in the environment. Therefore, after the quartz stone is poured out of the drying equipment, a large amount of dust will float into the environment, causing pollution to the working environment. Moreover, this dust is easy to be absorbed into the human body, endangering the health of on-site workers.

[0004] In order to avoid the large amount of dust on the surface of quartz stone floating in the working environment when it is poured out after drying, which would pollute the environment and affect the health of on-site personnel, this application proposes a drying oven for quartz stone production.

[0026] Please see Figures 1-2 A drying oven for quartz stone production includes a chamber body 1. A hot air blower 5 is fixedly connected to the top right side of the chamber body 1. A drain pipe 6 is fixedly connected to the output end of the hot air blower 5.

A rotating drum 11 is rotatably connected to the left end of the turntable 10. A gear ring 13 is fixedly connected to the right side of the outer wall of the rotating drum 11. A motor 8 is fixedly connected to the middle of the right end of the inner wall of the chamber body 1. A gear 9 is fixedly connected to the drive end of the motor 8. The upper and lower ends of the outer diameter of the gear 9 are respectively meshed with the gear ring 13. 3. At one end of the outer diameter, several holes are opened on the left side of the outer wall of the rotating cylinder 11. The inner wall of each hole is fixedly connected to an intercepting net 12. The left side of the inner wall of the diversion pipe 7 is fixedly connected to a shielding net 25. The rear end of the box body 1 is fixedly connected to a separation box 15. The top of the separation box 15 is fixedly connected to a suction pipe 14. The upper front end of the suction pipe 14 penetrates the inner wall of the box body 1. The middle of the inner wall of the separation box 15 is fixedly connected to a filter plate 22. The middle of the bottom end of the separation box 15 is fixedly connected to a negative pressure fan 24. The input end of the negative pressure fan 24 penetrates the inner wall of the separation box 15. The output end of the negative pressure fan 24 is fixedly connected to a guide pipe 18. The other end of the guide pipe 18 is fixedly connected to the rear end of the diversion pipe 6.

[0027] A rotating rod 4 is fixedly connected to the middle of the front end of the housing 1. A support frame 3 is rotatably connected to the front side of the outer wall of the rotating rod 4. A platform 2 is fixedly connected to the bottom of the rear end of the support frame 3. A worm gear 29 is fixedly connected to the front end of the rotating rod 4. An extension plate 26 is fixedly connected to both the left and right sides of the front end of the support frame 3, which is located below the worm gear 29. A worm 27 is rotatably connected to the right end of the left extension plate 26. The top end of the worm 27 is meshed with the bottom end of the outer diameter of the worm gear 29. A second motor 28 is fixedly connected to the right end of the right extension plate 26. The drive end of the second motor 28 passes through the left side of the extension plate 26 and is fixedly connected to the right end of the worm 27.

[0028] To further explain, firstly, start motor 28, whose drive end drives worm 27 to rotate. Worm wheel 29, meshing with the top of worm 27, rotates accordingly. Under the connecting action of rotating rod 4, housing 1 rotates clockwise and tilts to a set angle. Then, motor 28 stops running. At this point, open the door of housing 1, flip open the cover of rotating drum 11, and pour quartz into both rotating drums 11 in sequence. After loading an appropriate amount of quartz, close the cover first, then close the door. Next, start motor 28 again, causing its drive end to drive worm 27 in reverse. Worm wheel 29 and rotating rod 4 then rotate in reverse, driving... After the chamber 1 is rotated and reset, the hot air blower 5 is started. The hot air generated by the hot air blower 5 is discharged through the diversion pipe 6 and extended into the rotating drum 11 through the diversion pipe 7 to dry the quartz stone inside the rotating drum 11. At the same time, the motor 8 is started, and its drive end drives the gear 9 to rotate. The gear rings 13 located on both sides of the gear 9 mesh with the gear and drive the rotating drum 11 to rotate under the meshing transmission. During the drying process, the quartz stone inside the drum is turned over to ensure that the quartz stone is heated evenly and to improve the drying effect of the quartz stone. The shielding net 25 can prevent the quartz stone from falling into the diversion pipe 7 while ensuring the flow of hot air.

[0029] Example 2

[0030] Please see Figures 3-4 Further, based on Embodiment 1, an electric push rod 17 is fixedly connected to the right end of the separation box 15 on the upper side of the filter plate 22. The driving end of the electric push rod 17 penetrates the inner wall of the separation box 15 and is fixedly connected to a brush plate 19. The brush bristles at the bottom of the brush plate 19 are made of anti-static fiber material. A baffle 21 is provided on the left end of the separation box 15 on the upper inner wall of the filter plate 22. Connecting rods 20 are fixedly connected to both the front and rear sides of the right end of the baffle 21. The right ends of the connecting rods 20 are fixedly connected to the left end of the brush plate 19. The baffle 21 is used to block the opening of the separation box 15 to ensure the sealing of the separation box 15. A shelf 16 is fixedly connected to both the front and rear sides of the bottom end of the separation box 15. A receiving box 23 is provided on the lower inner wall of the left end of the shelf 16. A through groove is opened on the right end of the shelf 16 on one side of the baffle 21.

[0031] To further explain, during the quartz drying process, the dust adhering to the surface gradually dries. As the quartz is constantly turned, the dust floats and drifts into the chamber 1 through the interception net 12. Because the inner diameter of the mesh of the interception net 12 is relatively large, it can pass through small dust particles and intercept large quartz particles. At this time, the negative pressure fan 24 is started, and its input end generates negative pressure. The airflow carrying dust in the chamber 1 is introduced into the separation box 15 through the suction pipe 14. When the airflow passes through the filter plate 22, the dust is filtered on the surface of the filter plate 22. The filtered airflow is discharged into the drainage pipe 6 through the negative pressure fan 24 and the guide pipe 18, and re-enters the rotating drum 11 with the hot air to reduce heat loss.

[0032] The negative pressure fan 24 is turned off by the controller at a set time. Then, the electric push rod 17 is started. Its drive end pushes the brush plate 19 to move on the top of the filter plate 22. The connecting rod 20 drives the baffle 21 to move in the shelf 16. During the movement of the brush plate 19, the dust filtered on the surface of the filter plate 22 is pushed to one side and falls into the collection box 23, thus cleaning the surface of the filter plate 22 and preventing too much dust from affecting the airflow. After cleaning, the drive end of the electric push rod 17 is controlled to drive the brush plate 19 to reset and the negative pressure fan 24 is started again to continue to introduce the airflow with dust in the box 1 into the separation box 15, and filter it again through the filter plate 22. The above operation is repeated until the quartz stone is dried. Finally, the collection box 23 is pulled out from the shelf 16 and the collected dust is cleaned.

[0033] By starting motor 28, its drive end drives worm 27 to rotate, and worm wheel 29 meshing with the top of worm 27 rotates accordingly. Under the connection of rotating rod 4, box 1 rotates counterclockwise and tilts to a set angle, then motor 28 stops running. At this time, open the box door of box 1, flip open the cover of rotating drum 11, and pour out the quartz stones one by one.

[0034] Working principle: First, start motor 28, causing its drive end to rotate the worm 27, which in turn causes the worm wheel 29 meshing at the top of the worm 27 to rotate. Then, through the connection of the rotating rod 4, the housing 1 rotates clockwise and tilts to a certain angle. After that, motor 28 stops running. Next, open the door of housing 1 and flip open the cover plate of rotating drum 11. Then, pour quartz into the two rotating drums 11 one by one. After filling a certain amount, close the cover plate and then close the door. Then, start motor 28 again, causing its drive end to rotate the worm 27 in reverse, thereby causing the meshing worm wheel 29 to rotate. Wheel 29 rotates the rotating rod 4 in reverse, thereby causing the housing 1 to rotate and reset. Then, the hot air blower 5 is started to generate hot air, which is discharged through the drain pipe 6 and then discharged into the rotating drum 11 through the extension of the diverter pipe 7. This dries the quartz inside the rotating drum 11. At the same time, motor 8 is started, which drives the gear 9 to rotate. This causes the gear rings 13 on both sides of the gear 9 to rotate the rotating drum 11, thereby turning the quartz inside the rotating drum 11. This ensures that the hot air is evenly distributed in the rotating drum 11 and improves the drying effect on the quartz.

[0035] During the quartz drying process, the dust adhering to its surface gradually dries. As the quartz is turned, the dust floats and disperses into the chamber 1 through the interceptor mesh 12. Then, the negative pressure fan 24 is activated, creating negative pressure at its input end. This negative pressure then guides the dust-laden airflow from chamber 1 into the separation chamber 15 via the suction pipe 14. The airflow then passes through the filter plate 22, which filters the dust from its surface. The filtered airflow then passes through the negative pressure fan 24 and the guide pipe 18 before being discharged into the drain pipe 6. It then re-enters the rotating drum 11 with the hot air, thus reducing heat loss. The controller then timers the negative pressure fan 24 to shut off, and then activates the electric push rod 17, causing its drive end to push the brush plate 19 against the filter. The top of the screen plate 22 is displaced, which drives the baffle 21 to move within the shelf 16 via the connecting rod 20. Simultaneously, the brush plate 19 pushes the dust filtered on the surface of the screen plate 22 to one side until it falls into the collection box 23. This achieves simple cleaning of the surface of the screen plate 22, preventing excessive dust from affecting the airflow. Subsequently, the brush plate 19 is reset by controlling the drive end of the electric push rod 17. Then, the negative pressure fan 24 continues to run, and the airflow containing dust in the box 1 continues to be introduced into the separation box 15. The airflow is then filtered by the screen plate 22. The above operation process is repeated until the quartz stone is dried. After that, the collection box 23 is pulled out from the shelf 16 to clean the collected dust.
