Description

Technical Field

[0001] The present application relates to the field of food sterilization technology, and in particular to a steam recovery mechanism of a tunnel-type spray sterilizer. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the hygiene of food and beverages. They need a tunnel-type spray sterilization mechanism with low energy consumption, good sterilization effect and continuous operation, which includes a sterilization channel formed by a preheating tunnel box, a sterilization tunnel box, a pre-cooling tunnel box, and a cooling tunnel box connected in sequence, and a material conveying chain running through the sterilization channel.

[0003] The product is transported by the conveyor chain and enters through the end of the sterilization channel, that is, the entrance of the preheating tunnel box. Since the entrance of the preheating tunnel box is usually open, when high-temperature water is sprayed for sterilization, some water vapor is easily leaked, thus affecting the surrounding environment. Utility Model Content

[0004] In order to improve the problem of water vapor leakage at the entrance of the preheating tunnel box and affecting the surrounding environment, the present application provides a steam recovery mechanism for a tunnel-type spray sterilizer.

[0005] The steam recovery mechanism of a tunnel-type spray sterilizer provided in the present application adopts the following technical solution:

[0006] A steam recovery mechanism of a tunnel-type spray sterilizer comprises a conveying hood and a recovery hood, wherein both ends of the conveying hood are open, one end of the conveying hood is connected to the entrance of a preheating tunnel box, and the conveying hood is arranged outside a part of the conveying chain;

[0007] One end of the recovery hood is open and communicated with the interior of the conveying hood. The recovery hood is connected with an exhaust pipe communicated with the interior thereof, and the exhaust pipe is used to be connected with the fan suction system of the sterilizer.

[0008] By adopting the above technical solution, the conveying hood covers the inlet of the preheating tunnel box, preventing the water vapor from directly diffusing to the surroundings. The exhaust pipe draws air into the recovery hood through the sterilizer's fan suction system, so that the water vapor overflowing from the box inlet is recovered and reused, which saves water vapor resources on the one hand, reduces heat loss on the other hand, and reduces the impact on the surrounding environment.

[0009] Optionally, the conveying cover includes a bottom shell and a cover plate, the bottom shell has a U-shaped cross section and an opening facing upward, the cover plate is located above the bottom shell, and the cover plate is connected to the bottom shell via a spring buckle.

[0010] By adopting the above technical solution, the cover plate is buckled on the bottom shell by the spring buckle, so that the cover plate and the bottom shell are detachably connected, which is convenient for assembly and disassembly to inspect and repair the conveyor chain.

[0011] Optionally, the bottom shell includes a bottom plate and two folding plates, and the two folding plates are vertically connected to two sides of the bottom plate.

[0012] By adopting the above technical solution, the vertical connection between the folding plate and the bottom plate ensures the internal space of the bottom shell, which is conducive to stable support for the cover plate.

[0013] Optionally, the bottom plate and the two folding plates are integrally formed.

[0014] By adopting the above technical solution, the bottom plate and the folding plate are seamlessly connected, thereby ensuring the sealing between them. At the same time, the one-piece molding provides convenience for the bending process in actual processing, and the process is simple.

[0015] Optionally, the conveying cover includes a first straight line segment, an arc segment and a second straight line segment which are connected in sequence.

[0016] By adopting the above technical solution, the shape composed of the first straight line segment, the arc segment and the second straight line segment makes the conveying cover compatible with the conveying chain, which can save the space required for the conveying cover.

[0017] Optionally, the recovery hood is connected to the side wall of the preheating tunnel box and supported on the conveying hood.

[0018] By adopting the above technical solution, the water vapor density is less than the air density, and the recovery hood is located above the conveying hood, so that the water vapor moving upward can directly enter the recovery hood, which is beneficial to increase the efficiency of water vapor extraction.

[0019] Optionally, support rods are provided on both sides of the conveying cover, the bottom ends of the support rods are threadedly connected with vertically distributed studs, and the lower ends of the studs are fixed with pads.

[0020] By adopting the above technical solution, the support rod plays a supporting role for the conveying cover, reducing the possibility of the conveying cover bending downward due to its own weight.

[0021] Optionally, a clamping plate is provided on the side of the support rod facing away from the conveying cover, and a plurality of screws distributed on both sides of the support rod are vertically penetrated through the clamping plate, and each of the screws is threadedly connected to the conveying cover.

[0022] By adopting the above technical solution, the clamp presses the support rod against the side wall of the conveyor cover, so that the support rod is fixed to the conveyor cover; the operator can loosen the screws to move the support rod up and down, adjust the height position of the support rod, and ensure that the support rod effectively supports the ground; because the screws are distributed on both sides of the support rod, the support rod can be horizontally displaced within the spacing between the screws on both sides, thereby increasing the adjustable performance of the support rod.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The inlet of the preheating tunnel box is covered by the conveying hood, and the recovery hood is sucked by the exhaust pipe, so that the water vapor overflowing from the inlet of the box can be recovered and reused, which not only saves resources, reduces heat loss, but also reduces the impact on the surrounding environment;

[0025] 2. The cover of the conveyor cover can be opened to inspect the internal structure, which is convenient and flexible;

[0026] 3. The relative position between the support rod and the conveying cover is adjustable, and the spacing between the pad and the support rod is adjustable, which satisfies the docking of the conveying cover and the actual entrance position of the preheating tunnel box.

[0033] like Figure 1 The embodiment of the present application discloses a steam recovery mechanism of a tunnel-type spray sterilizer, including a conveying hood 1 and a recovery hood 2. The conveying hood 1 is open at both ends, one end of the conveying hood 1 is connected to the entrance of a preheating tunnel box 4, and the conveying hood 1 is arranged on the outside of a portion of the conveying chain 5, that is, the conveying chain 5 passes through the conveying hood 1 and then enters the box.

[0034] The recovery hood 2 is connected to the side wall of the preheating tunnel box 4 and supported on the conveying hood 1. The lower end of the recovery hood 2 is provided with an opening and is connected to the interior of the conveying hood 1. The upper end of the recovery hood 2 is connected to an exhaust pipe 21 connected to the interior of the recovery hood 2. The exhaust pipe 21 is used to be connected to the fan suction system of the sterilizer. The fan suction system of the sterilizer can achieve negative suction in the recovery hood 2 through the fan.

[0035] The conveyor cover 1 includes a first straight line segment, an arc segment and a second straight line segment connected in sequence, the first straight line segment is connected to the entrance of the preheating tunnel box 4, and the two ends of the arc segment are respectively adjacent to the first straight line segment and the second straight line segment to form an arc transition. The shape of the conveyor cover 1 is adapted to the transmission path of the conveyor chain 5, and the arc-shaped corner also has the effect of reducing the air flow speed. When water vapor overflows from the entrance of the preheating tunnel box 4, its speed of moving outside the conveyor cover 1 is slowed down.

[0036] like Figure 1 and Figure 2 , support rods 3 are provided on both sides of the conveying cover 1, and a clamping plate 33 is provided on the side of the support rod 3 away from the conveying cover 1, and a plurality of screws 34 distributed on both sides of the support rod 3 are vertically penetrated on the clamping plate 33, and each screw 34 is threadedly connected with the conveying cover 1. The clamping plate 33 presses the support rod 3 against the outer wall of the conveying cover 1 by locking the screws 34, so that the support rod 3 is fixed to the conveying cover 1, forming a support for the conveying cover 1, so that the conveying cover 1 remains horizontal.

[0037] like Figure 3The bottom ends of the support rods 3 are all threadedly connected with vertically distributed studs 31, and the lower ends of the studs 31 are fixed with pads 32. The operator can rotate the pads 32 to drive the studs 31 to rotate, and adjust the distance between the pads 32 and the support rods 3 by telescopic movement of the studs 31, thereby ensuring that the support rods 3 are effectively supported on the ground.

[0038] like Figure 1 and Figure 3 The conveyor cover 1 includes a bottom shell 10 and a cover plate 11. The cross-section of the bottom shell 10 is U-shaped and the opening is upward. The cover plate 11 is located above the bottom shell 10. The cover plate 11 is connected to the bottom shell 10 through a spring buckle 12. The spring buckle 12 is provided with two groups, which are respectively located on both sides of the cover plate 11. The cover plate 11 is fixed to the bottom shell 10 through the spring buckle 12. When it is necessary to inspect the inside of the bottom shell 10, it is only necessary to release the lock of the spring buckle 12, which is convenient and quick.

[0039] The bottom shell 10 includes a bottom plate 101 and two folding plates 102, the two folding plates 102 are vertically connected to the two sides of the bottom plate 101, and the bottom plate 101 and the two folding plates 102 are integrally formed. The bottom shell 10 is formed by stamping and folding a plate, and the two folding plates 102 and the bottom plate 101 form a U-shaped structure of the bottom shell 10. Since the bottom plate 101 and the two folding plates 102 are integrally formed, there is no gap between the bottom plate 101 and the folding plates 102, which improves the sealing performance of the bottom shell 10.

[0040] The support rod 3 is located outside the folding plate 102 , the screw 34 is threadedly connected to the folding plate 102 , and the support rod 3 and the folding plate 102 are fixed by the clamping plate 33 .

[0041] The entire conveying cover 1 can be made of food-grade stainless steel. When encountering high temperatures of water vapor during use, the metal material will not dissolve various alloys and harmful substances, thereby ensuring product safety.

[0042] The principle of the embodiment of the present application is as follows: the inlet of the preheating tunnel box 4 is covered by the conveying hood 1, and the fan suction system of the sterilizer exhausts air inside the recovery hood 2 through the exhaust pipe 21. When water vapor overflows from the box inlet, it is sucked away through the recovery hood 2 and the exhaust pipe 21, thereby preventing the water vapor from overflowing; in addition, the conveying hood 1 extends the path of the box inlet, and the inward airflow generated during the movement of the conveying chain 5 into the conveying hood 1 slows down the outward movement of water vapor, so that the water vapor is directly sucked away after overflowing, reducing the impact on the surrounding environment.

[0043] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
