Description

Technical Field

[0001] This utility model relates to the field of ventilation duct structure technology, specifically to a ventilation duct structure for improving quick-freezing tunnels. Background Technology

[0002] A quick-freezing tunnel is an industrial device used for the rapid freezing of food, pharmaceuticals, and other products. It uses low-temperature strong air or liquid nitrogen as a medium to force products through the maximum ice crystal formation zone in a short time, thus achieving rapid freezing and maintaining the product's quality, taste, and nutritional value. In the application of quick-freezing tunnels, the air duct structure is a key component to ensure the effective circulation of cold air and the transfer of heat.

[0003] When existing cold air flows inside the pipe, it tends to form laminar flow, which leads to increased boundary layer thermal resistance and insufficient heat transfer. In addition, the pipe installation requires a large number of bolts and nuts, making installation and disassembly time-consuming and labor-intensive. Utility Model Content

[0004] To address this issue, this invention provides an improved ventilation structure for quick-freezing tunnels, which solves the problems of laminar flow of cold air within the pipes, leading to increased boundary layer thermal resistance, insufficient heat transfer, and the need for a large number of bolts and nuts during pipe installation, resulting in time-consuming and labor-intensive installation and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved ventilation structure for quick-freezing tunnels, comprising a pipe body, wherein a flow-turbing component is provided inside the pipe body, and a plurality of assembly components are provided on one side of the pipe body; The flow-disrupting component includes a hydraulic push rod, which is fixedly mounted on one side of the pipe body. A connecting plate is fixedly connected to the output end of the hydraulic push rod. Horizontal plates are fixedly mounted on both sides of the connecting plate. Multiple toothed plates are fixedly mounted on one side of the horizontal plates. Multiple flow-disrupting units are provided inside the pipe body. Each flow-disrupting unit includes a rotating rod that passes through the pipe body and is connected to the pipe body via a sealed bearing. A flow-disrupting plate is fixedly mounted outside the rotating rod. A gear is fixedly connected to one end of the rotating rod, and the gear meshes with the toothed plate.

[0006] Preferably, the assembly includes a support frame, which is fixedly mounted on one side of the pipe body. A threaded rod is provided on one side of the support frame, which passes through the support frame and is connected to the support frame via a bearing. A knob is fixedly connected to one end of the threaded rod, and a retaining plate is threadedly fitted onto the outside of the threaded rod.

[0007] Preferably, the support frame is provided with a plurality of limiting rods inside, and the limiting rods pass through the card plate and are slidably connected to the card plate.

[0008] Preferably, limit grooves are provided on both sides of the pipe body, and limit strips are provided inside the limit grooves.

[0009] Preferably, a pull plate is fixedly provided on one side of the limiting strip.

[0010] Preferably, a sealing groove is provided on one side of the pipe body.

[0012] Preferably, a plurality of support frames are fixedly provided on one side of the pipe body, and a plurality of sliding columns are connected inside the support frames through bearings. The horizontal plate passes through the support frames and contacts the sliding columns.

[0013] Preferably, a slot is provided on the side of the pipe body away from the support frame.

[0014] The present invention has the following advantages: This invention, by setting up a turbulence-inducing component, uses a hydraulic push rod to drive the connecting plate, cross plate, and toothed plate to move, thereby driving the gear meshing with the toothed plate to rotate, causing the rotating rod to drive the turbulence-inducing plate to rotate. This design can flexibly control the turbulence-inducing angle of the turbulence-inducing plate, and force fluid mixing through local velocity differences, effectively breaking the laminar boundary layer formed by air flow in the pipe, reducing boundary layer thermal resistance, and allowing heat to be transferred more fully between the cold air and the object being quick-frozen, significantly improving the heat transfer coefficient of the quick-freezing tunnel, thereby improving the quick-freezing efficiency and meeting the industrial production demand for high-efficiency quick-freezing. This utility model adopts a unique assembly component design. When connecting pipes, simply connect the two pipe bodies, ensuring the sealing ring and sealing groove are accurately aligned to guarantee a seal. Insert the limiting strip into the limiting groove for initial positioning, and then rotate the knob to drive the threaded rod to rotate, causing the clamping plate to engage inside the clamping groove. This quickly and securely connects the two pipe bodies. This assembly method eliminates the cumbersome traditional installation method that uses a large number of bolts and nuts, greatly simplifying the installation and disassembly process, saving a significant amount of time and manpower, reducing installation costs, and facilitating subsequent maintenance and pipe replacement work, thus improving the maintainability of the entire quick-freezing tunnel system.
