Description

Technical Field

[0001] The present invention relates to the technical field of food quick-freezing cold chain technology, and in particular to a cold chain equipment temperature control system. Background Art

[0002] The rapid development of e-commerce and logistics industries has enabled consumers to get what they need for life without leaving home, especially seafood, fresh food, frozen food and refrigerated food, including meat, seafood, pastries, biological drugs, chemicals and other objects. Due to the special properties of fresh products and drugs, they face risks from various aspects during transportation. Among these risks, there are risks from facilities, which not only meet consumers' demand for healthy food, but also the inherent demand for the development of the industry itself, giving rise to the rapid development of the cold chain logistics industry.

[0003] For example, Chinese patent publication number: CN112460889B discloses a cold chain logistics box, which includes a box body, which is provided with a partition, the partition is fixedly connected to the box body, and divides the box body into a lower layer and an upper layer of the box body; a cold chain ventilation circulation structure, which includes a cold air circulation duct to cool the space in the lower layer of the box body; a heat dissipation ventilation circulation structure, which is located in the upper layer of the box body; a waterproof structure, which includes a first waterproof structure and a second waterproof structure, the first waterproof structure is arranged on the upper layer of the box body, and the second waterproof structure is arranged at the opening edge of the box body.

Example 2

[0041] like Figure 1-9As shown, on the basis of embodiment 1, the present invention provides a technical solution: preferably, a limiting collar is fixedly connected to one end of the wind source guide inclined plate C2, and a rotating rod C3 is movably sleeved on the inner surface of the limiting collar. A wind source transmission plate C4 is fixedly connected to the outer surface of the rotating rod C3, which is stacked on the surface of the wind source transmission plate C4. When the inclined surface of the wind source transmission plate C4 is impacted and pushed, the pushing force of the wind source transmission plate C4 is utilized. When the wind source transmission plate C4 rotates, the counterweight block on one end of the wind source transmission plate C4 is cooperated with. Under the action of inertia, the rotating rod C3 is driven to rotate inertially. The acceleration of inertia can accelerate the flow speed of the low-temperature wind source.

Example 3

[0042] like Figure 1-9As shown, based on Examples 1-2, the present invention provides a technical solution: preferably, the wind source diffusion unit includes a low-temperature cold air differentiater 25 fixedly mounted on the inner surface of the cavity, and air inlets a1 are provided on both sides of the low-temperature cold air differentiater 25. When the air inside the low-temperature guide pipe 26 is discharged, the low-temperature cold air is transferred into the low-temperature cold air differentiater 25 in conjunction with the air inlet a1. A fixed disc a2 is fixedly connected to the inner surface of the top of the low-temperature cold air differentiater 25, and a J-shaped guide differentiation strip a3 is staggered and fixedly connected to the bottom surface of the fixed disc a2. The J-shaped guide differentiation strip a3 on the bottom surface of the fixed disc a2 is fixedly connected to the bottom surface of the fixed disc a2. Strip a3 contacts the incoming air source, and cooperates with the curvature on one end of the J-shaped guide differentiation strip a3 to increase the air flow path. A rotating guide differentiation tube a4 is fixedly connected to the bottom surface of the low-temperature cold air differentiater 25. When the low-temperature cold air passes through the rotating guide differentiation tube a4, the vertical angle of the rotating guide differentiation tube a4 is used to make the air fall vertically. A fixed strip a31 is fixedly connected to the inner wall surface of the J-shaped guide differentiation strip a3, and a downward inclined guide plate a32 is fixedly connected to the outer surface of the fixed strip a31. Cooperating with the downward inclined guide plate a32, the incoming air source is guided downward so that the air source passes through the rotating guide differentiation tube a4 and is guided downward. Example 4

The inclined fixed thin plate a45 drives the trapezoidal swinging thin plate a44 to rotate while rotating. When the trapezoidal swinging thin plate a44 rotates, the diffused cold air is pushed to the surroundings to increase the diffusion range of the low-temperature cold air. The bottom end of the fixed thin strip a43 is fixedly connected with an inclined fixed thin plate a45, which contacts the vertically falling air according to the inclination angle of the inclined fixed thin plate a45. Example 5

[0044] like Figure 1-9As shown, on the basis of Examples 1-4, the present invention provides a technical solution: preferably, a swing docking positioning plate 12 is swingably connected to the front and rear side surfaces of the overlapping table 11, and the low-temperature control box 21 is overlapped on the top surface of the overlapping table 11. The swing docking positioning plate 12 is swung to clamp one end of it into the interior of the docking limit sleeve 23, and one end of the swing docking positioning plate 12 is movably sleeved on the inner surface of the docking limit sleeve 23. A shielding arm plate 14 is fixedly connected to the top left edge position of the overlapping table 11, and the top left edge position of the overlapping table 11 and the two side surfaces of the shielding arm plate 14 are located. A low-temperature hair dryer 13 is fixedly installed on it, and the output end of the low-temperature hair dryer 13 is movably sleeved on the left top surface of the low-temperature control box 21. A limiting clamping ring 15 that is movably overlapped on the top outer surface of the low-temperature control box 21 is movably sleeved on the outer surface of the overlapping table 11. The low-temperature control box 21 is fixedly installed on the top surface of the overlapping table 11, and then the limiting clamping ring 15 is sleeved on the top surface of the low-temperature control box 21, so that the bottom end of the limiting clamping ring 15 is clamped on the top outer surface of the overlapping table 11, and the low-temperature hair dryer 13 is used to infuse low-temperature cold air into the interior of the low-temperature control box 21.

[0045] The following is a detailed description of the working principle of the cold chain equipment temperature control system.

[0046] like Figure 1-9As shown, the low-temperature control box 21 is overlapped on the top surface of the overlapping table 11, and the swing docking positioning plate 12 is swung to clamp one end of it into the inside of the docking limit sleeve 23, and the low-temperature control box 21 is fixedly installed on the top surface of the overlapping table 11, and then the limiting clamping ring 15 is sleeved on the top surface of the low-temperature control box 21, so that the bottom end of the limiting clamping ring 15 is clamped on the top outer surface of the overlapping table 11, and the low-temperature blower 13 is used to infuse low-temperature cold air into the interior of the low-temperature control box 21, and the low-temperature guide pipe 26 is used to guide the cold air infused by the low-temperature blower 13 into the interior of the cavity, and the wind source guide inclined plate c2 on the inner surface of the fixed ring c1 is used to differentiate and guide the flowing cold air, and at the same time, the wind source guide is used to guide the cold air. The inclination angle on the surface of the inclined plate C2 makes the cold air in contact with the wind source guide inclined plate C2 spirally guide into the interior of the low-temperature guide tube 26, and the air blown along the spiral is accumulated on the surface of the wind source transmission plate C4. When the inclined surface of the wind source transmission plate C4 collides and pushes, the pushing force of the wind source transmission plate C4 is utilized. When the wind source transmission plate C4 rotates, the counterweight block on one end of the wind source transmission plate C4 is cooperated with. Under the action of inertia, the rotating rod C3 is driven to rotate inertially. The acceleration of inertia can accelerate the flow speed of the low-temperature wind source. The blowing speed of the low-temperature cold air will increase the pushing force on the wind source transmission plate C4 in the opposite direction, thereby driving the rotating rod C3 to rotate on one end of the wind source guide inclined plate C2. When the rotating rod C3 rotates, it drives the wind source swing The movable plate c5 rotates in the same direction, and the wind source swing plate c5, when rotating, utilizes the horizontal angle surface of the wind source swing plate c5 to push the flowing wind source to one side during rotation. After the air inside the low-temperature guide tube 26 is quickly discharged, a low-pressure environment will be created inside the low-temperature guide tube 26. Under the low-pressure environment, the air entry speed will also be increased. At the same time, the curvature of the semicircular guide arc strip c6 on one end of the rotating rod c3 is coordinated to increase the contact area and range with the wind source, and the guided air is quickly guided out along the wind source guide tube c7. When the air inside the low-temperature guide tube 26 is discharged, the low-temperature cold air is transferred into the low-temperature cold air differentiater 25 by cooperating with the air inlet a1, and the J-shaped guide divider on the bottom surface of the fixed disk a2 is coordinated. The strip a3 contacts the incoming wind source, and cooperates with the curvature on one end of the J-shaped guide and differentiation strip a3 to increase the air flow path, and cooperates with the downward inclined guide plate a32 to guide the incoming wind source downward so that the wind source passes through the rotating guide and differentiation cylinder a4 and is guided downward. When the low-temperature cold air passes through the rotating guide and differentiation cylinder a4, the vertical angle of the rotating guide and differentiation cylinder a4 is used to make the air fall vertically, and cooperates with the inclination angle of the inclined fixed thin plate a45 to contact the vertically falling air, pushing it so that the inclined fixed thin plate a45 drives the sliding ring a42 on the top of the fixed thin strip a43 to rotate on the top surface of the fixed ring a41, and while the inclined fixed thin plate a45 rotates, it drives the trapezoidal swinging thin plate a44 to rotate.The trapezoidal swinging plate a44 rotates and pushes the diffused cold air to the surroundings, increasing the diffusion range of the low-temperature cold air.

[0047] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
