Description

Technical Field

[0001] This utility model relates to the field of silo ventilation technology, specifically to a polypropylene product silo ventilation system. Background Technology

[0002] In the production and storage of polypropylene products, the ventilation system of the silo is crucial for ensuring product quality, production safety, and the health of the environment and personnel. Existing silo ventilation systems typically include filters to remove dust, but as the usage time increases, the filters become clogged with polypropylene dust, thus affecting the performance of the ventilation system.

[0003] Traditional filter cleaning methods mainly rely on manual operation, which not only consumes a lot of manpower and time, but also has many inconveniences in the cleaning process, such as the need to stop the machine and enter dangerous areas, which seriously affects production efficiency and continuous operation of equipment.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a polypropylene product silo ventilation system.

[0024] Reference Figure 1-3 A polypropylene product silo ventilation system includes a silo 1 and an exhaust fan 2. An exhaust vent is provided on one side of the silo 1. The exhaust fan 2 is fixedly installed outside the exhaust vent. A crossbar 3 is fixedly installed on the outer wall of the silo 1 below the exhaust fan 2. A rotating plate 4 is rotatably sleeved at the middle end of the crossbar 3. Filter shells 5 are fixedly installed on both sides of the rotating plate 4. Filter plates 6 are fixedly installed inside the filter shells 5. The side of the filter shell 5 closest to the exhaust fan 2 is open. A first sealing ring 10 is fixedly installed on the side of the filter shell 5 closest to the exhaust fan 2 to improve the sealing between the filter shell 5 and the exhaust fan 2, thus improving the filtration efficiency. A first through hole is provided on the other side of the shell 5. A connecting pipe 7 is fixedly installed on the outside of the first through hole. A connecting shell 8 is fixedly installed at the end of the crossbar 3 away from the hopper 1. A second through hole is provided at both ends of the connecting shell 8 near the connecting pipe 7. One end of the two connecting pipes 7 respectively abuts against the corresponding second through hole. A second sealing ring 11 is fixedly installed at the end of the connecting pipe 7 near the connecting shell 8 to improve the sealing between the connecting pipe 7 and the connecting shell 8. An exhaust port is provided in the lower groove of the connecting shell 8. A first solenoid valve 16 is fixedly installed inside the exhaust port. A second solenoid valve 17 is installed inside the lower second through hole.

[0025] Reference Figure 1-3 A dust collection shell 9 is fixedly installed on the outer wall of the hopper 1 and below the crossbar 3. The dust collection shell 9 has a material receiving port on the side near the filter shell 5. The opening of the filter shell 5 on the lower side abuts against the material receiving port. A cleaning port is opened at the bottom of the dust collection shell 9 and a cover plate is installed on the outside of the cleaning port to facilitate opening and cleaning of the collected dust.

[0026] The upper side of the dust collection shell 9 is provided with a transmission mechanism that drives the rotating plate 4 to rotate. The transmission mechanism includes a first bevel gear 13 and a second bevel gear 15. A rotating tube 12 is rotatably sleeved on the outer wall of the crossbar 3. One end of the rotating tube 12 is fixedly connected to the rotating plate 4. The first bevel gear 13 is fixedly sleeved on the end of the rotating tube 12 away from the rotating plate 4.

[0027] In this invention, during use, the exhaust fan 2 exhausts and removes dust from the hopper 1. During this process, the dust is filtered by the filter plate 6. At this time, the first solenoid valve 16 is open and the second solenoid valve 17 is closed, allowing the filtered air to be discharged smoothly. When it is necessary to clean the filter plate 5, the motor 14 drives the first bevel gear 13 to rotate, and the first bevel gear 13 drives the second bevel gear 15 to rotate, causing the rotating plate 4 to rotate around the crossbar 3. During this process, the filter shells 5 on both sides and the connecting pipe 7 exchange positions. When the exhaust and dust removal work continues, the clean filter plate 6 can continue to filter dust. At the same time, the first solenoid valve 16 is closed and the second solenoid valve 17 is opened, allowing the filtered air to enter the lower connecting pipe 7. Then, the dust attached to the lower filter plate 6 is blown into the dust collection shell 9, thus completing the automatic collection of dust. Then, the second solenoid valve 17 is closed and the first solenoid valve 6 is opened, allowing the normal exhaust work to continue.
