Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a cooling hopper arch breaking device specially used for hot viscous powder. Background Art

[0002] Material collectors are used in many industrial production systems to capture crystallized particles or powdered products. The capture operation can be intermittent or continuous. However, in large-scale production, intermittent operation is no longer sufficient. Production facilities of a certain scale must adopt continuous operation, making safe, reliable, and stable production equipment paramount. Therefore, the rational design and application of production equipment are crucial for safe, continuous production and improved labor intensity in factories. Due to various factors, the material in the product collector can sometimes compact and form an arch, preventing it from flowing, or partially preventing it from flowing, and preventing it from being discharged from the outlet, impacting production.

[0003] After searching, [Chinese Utility Model] CN201721572209.0 is a kind of arch breaker for breaking the arched material at the discharge port. The worm of the arch breaker drives the turbine turntable to rotate, and the material-moving rod on the turntable breaks up the material that has been arched or compacted, thereby ensuring that the material can smoothly flow out of the chemical continuous production device. The utility model uses the rotation of the material-moving rod to perform mechanical arch breaking, which is better than the arch breaking effect of the air-compressed arch breaker. However, in this solution, only the material-moving rod is used to break the material, and the contact area with the material is small, resulting in poor arch breaking effect. For hot sticky materials, if the hopper is directly connected to the injection molding machine, the friction of the material-moving rod and the heat transfer from the bottom will cause the material to heat up and stick together, making it difficult to break the arch with the above solution.

[0004] Therefore, how to provide a cooling type hopper arch breaking device specially designed for hot viscous powder to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0029] See also Figure 1-3 The present invention provides a technical solution for a cooling hopper arch-breaking device specially designed for hot viscous powder materials, comprising a power assembly, a transmission assembly, a connecting assembly, an arch-breaking assembly and a cooling assembly;

[0030] The connecting assembly includes a lower connecting flange 5 and an upper connecting flange 10, and the lower connecting flange 5 and the upper connecting flange 10 are fixedly connected by a connecting column 6;

[0031] The arch breaking assembly includes a rotating gear ring 4, a side scraper 12 and an arch breaking frame 13. The bottom end of the side scraper 12 is fixedly connected to the top end of the rotating gear ring 4 by a connecting buckle 11. The arch breaking frame 13 is fixedly connected to the side scraper 12. The arch breaking frame 13 increases the contact area with the material, thereby providing a better arch breaking effect. A T-shaped slot is opened on one side of the side scraper 12, and a scraper bar 22 is connected to the inside of the T-shaped slot.

[0032] The power assembly is in transmission connection with the rotating gear ring 4 via the transmission assembly.

[0033] The transmission assembly includes a transmission housing 3, one end of which is fixedly connected to one side of the lower connecting flange 5, and the two ends inside the transmission housing 3 are respectively rotatably connected to a transmission sprocket 18 and a transmission sprocket 2 21. The transmission sprocket 18 and the transmission sprocket 2 21 are connected by a transmission chain 19. The transmission sprocket 2 21 is coaxially connected to a meshing gear 20, and the meshing gear 20 is meshed with the rotating gear ring 4. The transmission sprocket 18 is larger than the transmission sprocket 21. The large sprocket drives the small sprocket, and the meshing gear 20 drives the gear ring 4 to rotate, thereby increasing the torque and achieving a better arch breaking effect.

[0034] The power assembly includes a motor 1, a gear housing 2, a drive gear 16 and a transmission gear 17. The motor 1 is installed on one side of the gear housing 2. The output shaft of the motor 1 is meshed with the drive gear 16, and the drive gear 16 is meshed with the transmission gear 17.

[0037] During specific use, the output shaft of the motor 1 drives the transmission gear 17 to rotate through the driving gear 16, and the transmission gear 17 drives the transmission sprocket 18 to rotate. The transmission sprocket 18 drives the meshing gear 20 to rotate through the transmission chain 19, and the meshing gear 20 drives the gear ring 4 to rotate, thereby driving the side scraper 12 to rotate. The side scraper 12 scrapes the inner wall of the silo through the scraper bar 22. At the same time, the side scraper 12 arches the material in the silo through the arch breaking frame 13 to avoid the accumulation of the material, so that the material can be discharged smoothly. At the same time, the external cooling gas enters the lower cooling chamber 15 through the air inlet pipe 7, and the cooling gas in the lower cooling chamber 15 is transported to the upper cooling chamber 14 through the connecting pipe 8. The cooling gas flows out through the return air pipe 9 to realize the circulation of the cooling air, avoiding the heat source contacted by the lower connecting flange 5 from being transmitted to the silo, achieving the effect of isolating the heat source, and thus preventing the material from agglomerating due to heat.
