DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-2, the present utility model provides a technical solution for the FFU clean air filtration system of a juice filling unit: An FFU clean air filtration system of a juice filling unit includes a top shell 1 and a bottom shell 13. The top shell 1 and the bottom shell 13 are connected by hinges and fixed buckles. A protective cover 2 is installed at the center of the top wall surface of the top shell 1. The periphery of the protective cover 2 is fixed to the top shell 1 by bolts 4. A filter screen 3 is provided at the center of the protective cover 2. An air inlet 6 is provided on the top wall surface of the top shell 1 below the protective cover 2. A sealing strip 5 is fixedly installed at the connection between the bottom wall surface of the periphery of the protective cover 2 and the air inlet 6. An air duct 12 is provided inside the top shell 1. A plurality of motor brackets 8 are connected to the inner wall surface of the air duct 12 towards the center. A plurality of the motor brackets 8 are fixedly connected to a motor housing 9. A motor 10 is installed inside the motor housing 9. The driving end of the motor 10 passes through the wall surface of the motor housing 9 and is connected to a driving shaft 11. An impeller 7 is sleeved outside the driving shaft 11. A limiting block 14 is fixedly installed on the inner bottom side wall surface of the top shell 1. A motor slot 15 is provided at the center of the top wall surface of the bottom shell 13. The motor housing 9 is located inside the motor slot 15. A filter element 16 is installed between the limiting block 14 and the bottom shell 13. A plurality of air outlets 17 are evenly provided on the wall surface of the bottom shell 13 below the filter element 16. An installation part 18 is fixedly installed on the outer wall surface of the top shell 1 by the bolts 4. A sealing cushion layer 19 is provided between the installation part 18 and the outer wall surface of the top shell 1. A wall panel 20 is installed in the slot of the installation part 18. A disinfection lamp strip 21 is embedded on the inner wall surface of the top shell 1.

[0017] Further, the installation part 18 is in a U-shaped structure. The bottom wall surface of the installation part 18 is on the same horizontal plane as the bottom wall surface of the top shell 1. The width of the slot of the installation part 18 is equal to the width of the wall panel 20.

[0018] Further, both the sealing cushion layer 19 and the sealing strip 5 are made of rubber structures.

[0019] Further, a circular arc chamfer structure is provided at the connection between the inner top wall surface and the inner side wall surface of the air duct 12. Further, the width of the air inlet 6 is greater than the diameter of the impeller 7.

[0020] Embodiment: When installing this device, a mounting groove with a suitable size is reserved on the wall panel 20. The installation part 18 is buckled on the peripheral side wall surfaces of the mounting groove. The sealing cushion layer 19 is fitted on the side wall surface of the installation part 18. Then, the top shell 1 is inserted into the mounting groove and the installation part 18 and the top shell 1 are fixed using bolts 4 to complete the installation of the device.

[0021] During use, the motor 10 is controlled to drive the impeller 7 to rotate. The impeller 7 adopts a centrifugal impeller structure. The external air is initially filtered through the filter 3 and then enters the air duct 12 through the air inlet 6, and then is filtered by the filter element 16 and discharged through the air outlet 17.

[0022] Large-diameter dust or fibers in the air are initially filtered on the surface by the filter screen 3, and small particles of dust are filtered by the filter element 16, so that the discharged air is clean and meets the specified conditions for juice filling.

[0023] During use, the disinfection light strip 21 on the inner wall of the top shell 1 emits light to illuminate the inside of the air duct 12, which can play a certain role in air sterilization. At the same time, the disinfection light strip 21 can also illuminate the surface of the filter element 16, which has a long-term irradiation and sterilization effect on the filter element 16, thereby preventing the growth of bacteria in the filter element 16.

[0024] During maintenance or cleaning, the protective cover 2 can be removed. Since the width of the air inlet 6 is greater than the diameter of the impeller 7, the impeller 7 can be directly removed from the air inlet 6 for cleaning. At the same time, since the bottom shell 13 and the top shell 1 are connected by hinges and fixed buckles, the bottom shell 13 can be opened and the filter element 16 can be removed and replaced.

[0025] The device has a compact structure and a thin width, can save space and improve applicability.

[0026] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.
