Description

Technical Field

[0001] This utility model relates to the field of ventilation structure technology, and in particular to a circulating ventilation structure for a cold storage facility for agricultural crops. Background Technology

[0002] A cold storage facility is a building used to store goods (especially perishable foods such as crops, meat, and seafood) in a low-temperature environment. It creates and maintains a suitable environment of low temperature, humidity, and gas composition through artificial refrigeration, thereby extending the shelf life and freshness of the stored goods. Cold storage facilities require ventilation to operate. Without ventilation, cold air will naturally sink, resulting in lower temperatures near the evaporator and higher temperatures in areas farther away, creating a significant temperature gradient within the cold storage.

[0003] Current ventilation methods generally involve blowing air directly through fans. This method concentrates the airflow in one direction within the cold storage, resulting in relatively poor diffusion and thus reducing the air circulation within the cold storage.

[0004] Therefore, it is necessary to provide a new circulating ventilation structure for cold storage of crops to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a circulating ventilation structure for cold storage of crops.

[0006] The circulating ventilation structure for cold storage of crops provided by this utility model includes: a mounting plate and a support frame. A fan is provided on one side inside the mounting plate, and a filter box is provided on the other side inside the mounting plate. Two support frames are provided and symmetrically distributed. The two support frames are set inside the cold storage, and an exhaust assembly is provided between the two support frames.

[0007] The exhaust assembly includes a horizontal connecting pipe, which is located at the inner top of the support frame. An air guide hood is installed between the horizontal connecting pipe and the output end of the fan. A vertical connecting pipe is provided at the end of the horizontal connecting pipe. A sliding shell is slidably connected to the outside of the vertical connecting pipe. The inside of the sliding shell is connected to the inside of the vertical connecting pipe. An exhaust plate is installed between the two sliding shells.

[0008] The support frame is equipped with a rotatably connected reciprocating screw, and the reciprocating screw is threadedly connected to the exhaust plate.

[0009] Preferably, air outlets are inserted into the four corners of the mounting plate, a support frame is installed inside the air outlet, a slidably connected sealing frame is inserted inside the support frame, and the end of the sealing frame abuts against the end of the air outlet.

[0010] Preferably, a spring b is provided between the sealing frame and the support frame, one end of the spring b is fixedly connected to the sealing frame, and the other end of the spring b is fixedly connected to the support frame.

[0011] Preferably, the side wall of the vertical connecting pipe is provided with a plurality of evenly distributed mounting grooves, and a mounting bracket is inserted inside the mounting groove. The mounting bracket is provided with a slidably connected sealing magnetic sheet inside, and the outer wall of the sealing magnetic sheet abuts against the inner wall of the mounting bracket.

[0012] Preferably, a spring a is provided between the mounting bracket and the sealing magnetic sheet, one end of the spring a is fixedly connected to the mounting bracket, and the other end of the spring a is fixedly connected to the sealing magnetic sheet.

[0013] Preferably, a magnetic block is fixedly connected inside the sliding shell, and the magnetic block and the sealing magnetic sheet have the same magnetism.

[0014] Compared with related technologies, the circulating ventilation structure for cold storage of crops provided by this utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of the movable exhaust plate in the exhaust assembly, can evenly blow the air blown by the fan in the cold storage by moving the exhaust plate back and forth above during use, thereby making the air flow in the cold storage more uniform and improving the gas circulation effect inside the cold storage.

[0016] 2. This utility model sets the air outlet at the end of the mounting plate away from the fan outlet. During use, when the gas blown by the fan flows to the other side of the cold storage, the air that is in contact with the side wall of the cold storage will flow back in the opposite direction until the air pressure inside the cold storage is greater than the force of the spring b on the sealing frame. At this point, the gas will push the sealing frame outward, releasing the seal on the air outlet and allowing the gas to be discharged outward. This allows the gas entering the cold storage to circulate within the cold storage, thereby further improving the air circulation effect of this device. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6 The present invention provides a circulating ventilation structure for a cold storage facility for crop storage, which includes: a mounting plate 1 and a support frame 3.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 6 A fan 2 is provided on one side of the mounting plate 1, and a filter box 21 is provided on the other side of the mounting plate 1. Two support frames 3 are provided and symmetrically distributed. The two support frames 3 are set in the cold storage, and an exhaust assembly 4 is provided between the two support frames 3. The exhaust assembly 4 includes a horizontal connecting pipe 41, which is set at the top inside the support frame 3. An air guide hood 411 is installed between the horizontal connecting pipe 41 and the output end of the fan 2. A vertical connecting pipe 42 is provided at the end of the horizontal connecting pipe 41. A sliding shell 43 is slidably connected to the outside of the vertical connecting pipe 42. The inside of the sliding shell 43 is connected to the inside of the vertical connecting pipe 42, and an exhaust plate 44 is installed between the two sliding shells 43. A reciprocating screw 5 is rotatably connected inside the support frame 3, and the reciprocating screw 5 is threadedly connected to the exhaust plate 44.

[0028] It should be noted that during use, the working fan 2 will transport outside air into the cold storage, and the filter box 21 located outside the mounting plate 1 can filter the air, thereby making the air entering the cold storage cleaner.

[0029] The gas discharged from the output end of the fan 2 flows into the horizontal connecting pipe 41 and the vertical connecting pipe 42 through the air guide shroud 411. At the same time, the rotating reciprocating screw 5 drives the exhaust plate 44 and the sliding shell 43 to move up and down synchronously, so that the interior of the sliding shell 43 can smoothly connect with the mounting slots 421 at different positions in the vertical connecting pipe 42. This allows the air inside the vertical connecting pipe 42 to flow into the exhaust plate 44 through the sliding shell 43 and then flow into the cold storage through the exhaust head on the outer wall of the exhaust plate 44. The up and down reciprocating movement of the exhaust plate 44 allows the gas to be discharged at different heights in the cold storage, thus improving the uniformity of gas discharge inside the cold storage.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 6 Air outlets 6 are inserted into the four corners of the mounting plate 1. A support frame 61 is installed inside the air outlet 6. A slidably connected sealing frame 62 is inserted inside the support frame 61. The end of the sealing frame 62 abuts against the end of the air outlet 6. A spring b63 is installed between the sealing frame 62 and the support frame 61. One end of the spring b63 is fixedly connected to the sealing frame 62, and the other end of the spring b63 is fixedly connected to the support frame 61.

[0031] It should be noted that: by sliding the sealing frame 62 and connecting it to the support frame 61 with the spring b63, in the initial state, the spring b63 can pull the sealing frame 62 with its own force, so that the end of the sealing frame 62 can seal the end of the air outlet 6, thus reducing the phenomenon of dust in the outside air entering the cold storage through the air outlet 6.

[0032] During use, when the air pressure inside the cold storage exceeds the force exerted by the spring b63 on the sealing frame 62, the gas will push the sealing frame 62 outward, releasing the seal on the air outlet 6 and allowing the gas to be discharged outward. This allows the gas entering the cold storage to circulate within the cold storage, thereby further improving the air circulation effect of the device.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 6The side wall of the vertical connecting pipe 42 is provided with several evenly distributed mounting slots 421. A mounting bracket 45 is inserted into the mounting slot 421. A slidably connected sealing magnetic sheet 451 is provided inside the mounting bracket 45, and the outer wall of the sealing magnetic sheet 451 abuts against the inner wall of the mounting bracket 45. A spring a452 is provided between the mounting bracket 45 and the sealing magnetic sheet 451. One end of the spring a452 is fixedly connected to the mounting bracket 45, and the other end of the spring a452 is fixedly connected to the sealing magnetic sheet 451. A fixedly connected magnetic block 431 is provided inside the sliding shell 43, and the magnetic block 431 and the sealing magnetic sheet 451 have the same magnetism.

[0034] It should be noted that since the magnetic block 431 and the sealing magnetic sheet 451 have the same magnetism, during use, when the sliding shell 43 moves the magnetic block 431 to the position opposite to the sealing magnetic sheet 451, the repulsive force between the magnetic block 431 and the sealing magnetic sheet 451 can move the sealing magnetic sheet 451 away from the magnetic block 431, thereby releasing the seal on the hole in the mounting bracket 45 and allowing the gas in the vertical connecting pipe 42 to flow into the sliding shell 43.

[0035] With the spring a452 in place, in the initial state, the spring a452 will squeeze the sealing magnetic sheet 451 with its own force, so that the sealing sheet can successfully seal the hole in the mounting bracket 45, thus preventing the gas in the vertical connecting pipe 42 from leaking randomly.

[0036] The working principle of the circulating ventilation structure for cold storage of crops provided by this utility model is as follows:

[0037] When using this device, first install it on the side wall of the cold storage using the mounting plate 1, then remove the support frame 3 and install it on the inner wall of the cold storage. Then, connect the output end of the fan 2 to the horizontal connecting pipe 41 through the air guide hood 411 to complete the installation of this device.

[0038] When the staff controls the fan 2 to work, the working fan 2 can transport the air from the outer wall to the inside of the cold storage through the filter box 21. At this time, the gas discharged from the output end of the fan 2 will flow into the horizontal connecting pipe 41 and the vertical connecting pipe 42 through the air guide hood 411. At the same time, the reciprocating screw 5 can be controlled to rotate, and the rotating reciprocating screw 5 drives the exhaust plate 44 to move up and down in the vertical direction.

[0039] The moving exhaust plate 44 will drive the sliding shell 43 to move synchronously outside the vertical connecting pipe 42. When the magnetic block 431 inside the sliding shell 43 moves to the position opposite to the sealing magnetic sheet 451 inside the vertical connecting pipe 42, the repulsive force between the magnetic block 431 and the sealing surface can drive the sealing magnetic sheet 451 to move away from the magnetic block 431, so that the sealing magnetic sheet 451 can contact the seal of the opening inside the mounting bracket 45. At this time, the air inside the vertical connecting pipe 42 will flow into the exhaust plate 44 through the sliding shell 43 and flow into the cold storage through the exhaust head on the outer wall of the exhaust plate 44. By moving the exhaust plate 44 up and down, the gas can be discharged at different heights inside the cold storage, thus improving the uniformity of gas discharge inside the cold storage.

[0040] Since the air outlet 6 is located at the end of the mounting plate 1 away from the air outlet of the fan 2, when the gas blown by the fan 2 flows to the other side of the cold storage, the air that is in contact with the side wall of the cold storage will flow back in the opposite direction until the air pressure inside the cold storage is greater than the force of the spring b63 on the sealing frame 62. At this point, the gas will push the sealing frame 62 outward, releasing the seal on the air outlet 6 and allowing the gas to be discharged outward. This allows the gas entering the cold storage to circulate within the cold storage, thereby further improving the air circulation effect of the device and making the temperature inside the cold storage more uniform. Therefore, it can improve the preservation effect of crops stored in the cold storage.

[0041] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
