The side cover plates on both sides can be opened so that an operator can clean the interior of the side cover plates. The wind shield at the inlet can downwards concentrate cold air overflowed from the tunnel, so that the cold air is better sucked by the air suction openings at the two sides.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an exhaust device in liquid nitrogen quick-freeze tunnel, is including setting up the box of airing exhaust at liquid nitrogen quick-freeze tunnel pan feeding mouth, its characterized in that, the box of airing exhaust falls the U-shaped casing by cavity and anti-C shape is aired exhaust the bounding wall and is constituteed, the blind end orientation of the bounding wall of airing exhaust the outside of pan feeding mouth, the cavity is fallen the U-shaped casing and is set up pan feeding mouth top just the bounding wall of airing exhaust with the bottom plate in the feeding guipure outside of pan feeding mouth laminates mutually, the bounding wall inboard of airing exhaust be provided with the air exhaust duct that cavity is fallen U-shaped casing inner chamber and is linked together just air exhaust duct is provided with the inlet scoop towards the side of pan feeding mouth, cavity is fallen U-shaped casing top and is provided with the interface of airing exhaust of connecting air extracting equipment.
Furthermore, a wind shield is arranged at the position, communicated with the feeding port, of the front face of the hollow inverted-U-shaped shell, and the wind shield is fixed on the outer wall of the hollow inverted-U-shaped shell through a bolt.
Furthermore, a longitudinal bolt sliding groove is formed in the wind shield, and the bolt penetrates through the bolt sliding groove to fix the wind shield on the outer wall of the hollow inverted-U-shaped shell.
Furthermore, the cavity is provided with clean mouthful in the shell both sides of falling the U-shaped, just be provided with the side cover board that can open on the clean mouthful, the inlet scoop is provided with detachable grid form inlet scoop apron.
Further, the air suction openings are arranged on two sides of the feeding mesh belt.
The utility model discloses compare with prior art, its effect is positive and obvious, the utility model discloses the inlet scoop design of both sides is compared in the design of general air exhaust has better effect of airing exhaust, at pan feeding section guipure surface formation air curtain, isolated a large amount of air suction tunnels and reduce tunnel efficiency when reducing the cold volume loss in the tunnel, can effectively improve the abominable processing environment in processing scene, guarantee production and processing personnel's life safety and healthy, and exhaust system's cleanness is convenient and fast more, effectively improve the health of processing environment, accord with food processing hygienic standard.

Detailed Description
Example (b):
as shown in fig. 1, 2 and 3, an exhaust device for liquid nitrogen quick-freezing tunnel comprises an exhaust box body arranged at a feeding port (not shown) of the liquid nitrogen quick-freezing tunnel, and is characterized in that the exhaust box body is composed of a hollow inverted U-shaped shell 2 and an inverted C-shaped exhaust baffle 1, the closed end of the exhaust baffle 1 faces the outside of the feeding port, the hollow inverted U-shaped shell 2 is arranged above the feeding port, the exhaust baffle 1 is attached to a bottom plate outside a feeding mesh belt of the feeding port, an exhaust duct communicated with an inner cavity 6 of the hollow inverted U-shaped shell 2 is arranged inside the exhaust baffle 1, an air suction port 4 is arranged on the side of the exhaust duct facing the feeding port, an exhaust port 7 connected with an air suction device is arranged at the top of the hollow inverted U-shaped shell 2, and the design of the air suction ports 4 on two sides has a better exhaust effect compared with the common design of exhaust, the power consumption of the air draft equipment can be effectively reduced.
Further, as shown in fig. 1 and 2, the front side of the hollow inverted U-shaped shell 2 is communicated with the feeding port, and a wind shield 3 is arranged at the position of the feeding port, the wind shield 3 is fixed on the outer wall of the hollow inverted U-shaped shell 2 through a bolt 8, the wind shield 3 can downwards concentrate cold air overflowing from the tunnel, so that the cold air is better sucked by the suction ports 4 at two sides, and the wind shield 3 can be detached to facilitate operation and cleaning.
