Description

Technical Field

[0001] This utility model relates to the technical field of ventilation devices for silicone production workshops, specifically a ventilation device with purification function for silicone production workshops. Background Technology

[0002] The silicone production process (such as mixing, vulcanization, extrusion, and molding) generates volatile organic compounds (VOCs, such as decomposition products of vulcanizing agents and solvent volatiles), dust (such as silica and silicone powder), and hot exhaust gases. If these are not removed in a timely manner, they can harm the health of operators (such as irritating the respiratory tract and causing allergies) and may also affect product quality (such as dust adhesion leading to defects in silicone products). Ventilation devices are the core equipment for "pollution control, temperature control, and safety assurance" in silicone workshops.

[0003] For example, the utility model disclosed in announcement number CN220072660U discloses a ventilation device for silicone production. This ventilation device can automatically adjust the orientation of the suction structure during the suction process, thereby achieving the absorption of gas from different directions, improving ventilation efficiency, and intercepting and cleaning dust while ventilating. When the fan blades rotate and generate wind force to blow towards the ventilation pipe, the connecting pipe is in a negative pressure state. Therefore, the gas in the workshop can be drawn out through the air inlet pipe to achieve ventilation. At the same time as suction, the dust in the gas can be intercepted by the filter screen. In this way, the rotation of the drive shaft can drive the brush rod to sweep on the filter screen, which plays a role in cleaning dust.

[0004] In the above-mentioned ventilation device, when in use, the dust at the air inlet is intercepted by the filter to prevent the dust from entering the ventilation device, thereby purifying the extracted airflow. The transmission mechanism drives the cleaning brush to rotate and clean the filter. However, since the cleaned dust is not collected, the dust will still remain in the ventilation device. When the exhaust fan is started, the dust will still be attracted to one side of the filter, making it difficult to ensure smooth air extraction by the ventilation device. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilation device with purification function for silicone production workshops, in order to solve the problem mentioned in the background art. When the existing ventilation device is in use, it uses a filter to intercept dust at the air inlet to prevent dust from entering the ventilation device, thereby purifying the extracted airflow. It also uses a transmission mechanism to drive a cleaning brush to rotate and clean the filter. However, since the cleaned dust is not collected, the dust still remains in the ventilation device. When the exhaust fan is started, the dust will still be attracted to one side of the filter, making it difficult to ensure smooth air extraction of the ventilation device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation device with purification function for a silicone production workshop, comprising a housing, an exhaust port connected to one side of the housing via a pipe, an exhaust fan installed on the side of the housing away from the exhaust port, a vacuum cleaner installed at the bottom of the exhaust fan, and one side of the vacuum cleaner fixedly mounted to the housing; multiple sets of filter plates are installed and fixed inside the housing, a cleaning brush is provided on one side of each filter plate, a crossbar a is rotatably connected to one side of each cleaning brush via a rotating shaft, a connecting plate is fixedly connected to the bottom of the crossbar a, a reciprocating motion mechanism is provided at the bottom of the connecting plate, a baffle is fixedly connected to one side of the crossbar a, and the outer side of the baffle is slidably connected to the housing; a guide mechanism for guiding the cleaning brush is provided on one side of each filter plate.

[0007] Furthermore, the reciprocating motion mechanism includes motors installed on both sides of the bottom of the housing, a lever fixedly connected to the output end of the motor, a lever rotatably connected to a toggle block via a rotating shaft at one end, a crossbar b slidably connected to the outer side of the toggle block, and a dust discharge groove provided on one side of the bottom of the filter plate.

[0008] Furthermore, a horizontal plate is fixedly connected to one side of the crossbar b, and the top of the horizontal plate is fixedly connected to the connecting plate.

[0009] Furthermore, the guiding mechanism includes two sets of vertical rods arranged on one side of the filter plate, and one side of the vertical rods is fixedly connected to both sides inside the housing.

[0010] Furthermore, a movable rod is slidably connected to one side of the vertical rod. The two ends of the movable rod are wedge-shaped. Multiple sets of springs a are fixedly connected to one side of the movable rod, and one side of the multiple sets of springs a is fixedly connected to the inner side of the vertical rod.

[0011] Furthermore, both ends of the cleaning brush are fixedly connected to protrusions, one side of which is trapezoidal, and one side of the cleaning brush abuts against a spring b, one end of which is fixedly connected to a connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the silicone production workshop uses a ventilation device with purification function, which can purify the exhaust gas through multiple sets of internal filter plates. By starting the reciprocating motion mechanism, the cleaning brush can be driven to move up and down back and forth to clean the filter plate on one side, ensuring the purification effect of the filter plate. The guide mechanism can prevent the cleaning brush from cleaning the filter plate when it moves up, thus preventing the dust generated during cleaning from being re-adsorbed onto the filter plate.

[0013] 1. By starting the reciprocating motion mechanism, the horizontal bar A and the cleaning brush move up and down to clean the filter plate on one side. Then, the dust is collected by the vacuum cleaner. When the horizontal bar A moves, it will also move the baffle, thereby blocking the dust cleaned by the cleaning brush and preventing the suction generated by the exhaust fan from bringing the dust back to the side of the filter plate.

[0014] 2. When the cleaning brush moves upward, it will contact the wedge-shaped surface at the bottom of the moving rod through the protrusions at both ends. At this time, the cleaning brush can rotate and will not contact the filter plate. When the cleaning brush moves to the highest point, spring b will push the cleaning brush to return to its original position. When the cleaning brush moves downward, it will cause the protrusions to contact the wedge-shaped surface at the top of the moving rod. At this time, the cleaning brush will not be able to rotate and can squeeze the moving rod. The cleaning brush that cannot rotate will clean the filter plate when it moves downward.

[0017] 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.

[0018] Example 1: Please refer to Figures 1-3 This utility model provides the following technical solution: A ventilation device with purification function for a silicone production workshop, comprising a housing 1, an exhaust port 2 connected to one side of the housing 1 via a pipe, an exhaust fan 3 installed on the side of the housing 1 away from the exhaust port 2, a vacuum cleaner 4 installed at the bottom of the exhaust fan 3, and one side of the vacuum cleaner 4 fixedly installed to the housing 1; multiple sets of filter plates 5 are installed and fixed inside the housing 1, a cleaning brush 8 is provided on one side of the filter plate 5, a crossbar a7 is rotatably connected to one side of the cleaning brush 8 via a rotating shaft, a connecting plate 6 is fixedly connected to the bottom of the crossbar a7, a reciprocating motion mechanism is provided at the bottom of the connecting plate 6, a baffle 14 is fixedly connected to one side of the crossbar a7, and the outer side of the baffle 14 is slidably connected to the housing 1; this ventilation device with purification function for a silicone production workshop, in order to purify the air, can effectively purify the air. When the workshop is ventilated, the exhaust fan 3 is started. The exhaust fan 3 transmits suction to the exhaust port 2 through the pipe, thereby drawing out the gas in the workshop. The gas is purified by passing through multiple sets of filter plates 5 and then discharged. When the filter plates 5 need to be cleaned, the reciprocating motion mechanism is started to drive the crossbar a7 and the cleaning brush 8 to move up and down. When the cleaning brush 8 moves, it cleans one side of the filter plate 5, causing the dust on one side of the filter plate 5 to fall to the bottom and enter the lower half of the box 1 through the dust discharge trough 20. Then, the vacuum cleaner 4 collects the dust. At the same time, when the crossbar a7 moves, it also drives the baffle 14 to move, thereby blocking the dust cleaned down from one side of the cleaning brush 8 and preventing the suction generated by the exhaust fan 3 from bringing the dust back to one side of the filter plate 5.

[0019] Please see Figures 2-4 The reciprocating motion mechanism includes motors 9 installed on both sides of the bottom of the housing 1. The output end of the motor 9 is fixedly connected to a lever 10. One end of the lever 10 is rotatably connected to a toggle block 11 via a rotating shaft. A crossbar b12 is slidably connected to the outside of the toggle block 11. A dust discharge groove 20 is provided on one side of the bottom of the filter plate 5. When the reciprocating motion mechanism moves, the motor 9 will drive the lever 10 to rotate, and the toggle block 11 at one end of the lever 10 will slide in the strip groove inside the crossbar b12, thereby moving the crossbar b12 up and down. The crossbar b12 will drive the horizontal plate 13 to move.

[0020] Please see Figures 2-4A horizontal plate 13 is fixedly connected to one side of the horizontal bar b12, and the top of the horizontal plate 13 is fixedly connected to the connecting plate 6. The horizontal plate 13 will drive multiple sets of connecting plates 6 to move up and down reciprocally, while the connecting plates 6 will drive the cleaning brush 8 at the top to move reciprocally.

[0021] The above operations facilitate the purification of the gas discharged from the ventilation system of the silicone production workshop and keep the filter plate 5 unobstructed.

[0022] Example 2: Please see Figures 3-4 and Figures 5-7 Based on Embodiment 1, a guiding mechanism for guiding the cleaning brush 8 is also disclosed, the specific structure of which is as follows: A guiding mechanism for guiding the cleaning brush 8 is provided on one side of the filter plate 5. The guiding mechanism includes two sets of vertical rods 16 provided on one side of the filter plate 5, and one side of the vertical rods 16 is fixedly connected to both sides inside the housing 1; a movable rod 17 is slidably connected to one side of the vertical rod 16. The two ends of the movable rod 17 are wedge-shaped. Multiple sets of springs a18 are fixedly connected to one side of the movable rod 17, and one side of the multiple sets of springs a18 is fixedly connected to the inner side of the vertical rod 16; both ends of the cleaning brush 8 are fixedly connected to protrusions 15. One side of the protrusions 15 is trapezoidal. One side of the cleaning brush 8 abuts against a spring b19, and one end of the spring b19 is fixedly connected to the connecting plate 6.

[0023] Please see Figures 3-4 and Figures 5-7 The silicone production workshop uses a ventilation system with purification function. When cleaning the filter plate 5, to prevent the cleaning brush 8 from contacting the filter plate 5 during upward movement and causing dust to fall off, thus preventing the baffle 14 from blocking the suction force generated by the vacuum cleaner 4, two sets of vertical rods 16 are installed on one side of the baffle 14. A movable rod 17 is installed on one side of each vertical rod 16. When the cleaning brush 8 moves upward, it contacts the wedge-shaped surface at the bottom of the movable rod 17 through the protrusions 15 at both ends. At this time, the cleaning brush 8 can rotate and compress the spring b19 on one side. After rotation, the cleaning brush 8 will not contact the filter plate 5. To prevent the cleaning brush 8 from being cleaned, when the cleaning brush 8 moves to the highest point, the spring b19 will push the cleaning brush 8 to return to its original position. When the cleaning brush 8 moves down, it will cause the protrusion 15 to contact the wedge-shaped surface at the top of the moving rod 17. At this time, since the top of the cleaning brush 8 is in contact with one side of the crossbar a7, the cleaning brush 8 will not be able to rotate and can squeeze the moving rod 17, so that the moving rod 17 squeezes the multiple sets of springs a18 on one side. At this time, the cleaning brush 8 will clean the filter plate 5 when it moves down. In this way, the above operation can prevent the dust after cleaning on the filter plate 5 from returning to the filter plate 5.
