Description

Technical Field

[0001] This utility model belongs to the technical field of persimmon production equipment, specifically, it relates to an indoor ventilation system for persimmon production. Background Technology

[0002] In the process of large-scale production of persimmons, the ventilation system in the production room directly affects the processing quality and storage period of the persimmons.

[0003] Existing ventilation systems in persimmon production facilities typically employ either top-mounted unified air supply or fixed side-wall vents, which present the following problems: Persimmons are usually layered on shelves, and traditional air supply methods often result in excessive airflow to the upper layers and insufficient airflow to the lower layers, leading to excessive moisture loss from the upper layers and incomplete drying or low pre-cooling efficiency in the lower layers; they also cannot adapt to the needs of multiple stages. Draining persimmons after washing requires low-speed, wide-coverage ventilation, while pre-cooling requires medium-to-high-speed, directional cooling ventilation, and existing systems cannot flexibly adjust airflow speed and direction according to different production stages; to meet the ventilation needs of the lower layers of persimmons, the overall fan power needs to be increased, resulting in energy waste and failing to meet energy conservation and environmental protection requirements.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an indoor ventilation system for persimmon production, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A ventilation system for a persimmon production room includes: a support frame, a main air guide pipe, branch air guide pipes, a wind speed control component, and an angle adjustment component. The main air guide pipe is horizontally installed on the side wall or top of the persimmon production room, with one end connected to the air outlet of the ventilation system's fan. Several connecting pipe interfaces are provided along the length of the pipe. Each layer of the support frame has connecting blocks on both sides, and each connecting block is connected to a branch air guide pipe via the angle adjustment component. The branch air guide pipe has air guide holes on its surface, and a connecting pipe connects the main air guide pipe to the connecting blocks. The wind speed control component includes an electric air valve and a controller. The electric air valve is installed at the connection between the connecting pipe and the branch air guide pipe, and the electric air valve and the controller are electrically connected.

[0008] Optionally, the angle adjustment assembly includes a connecting ring and a connecting sleeve, the connecting sleeve being connected to the side wall of the connecting block, the connecting sleeve being threadedly connected to the air guide branch pipe, and the connecting ring being located on the surface of the air guide branch pipe.

[0009] Optionally, the connecting ring is fixedly connected to the surface of the air guide branch pipe and is located at the end where the air guide branch pipe is connected to the connecting sleeve, and a friction layer is formed on the surface of the connecting ring.

[0010] Optionally, the connecting block has a connecting channel, one end of which is connected to the connecting pipe, and the other end of which passes through the connecting sleeve and is connected to the air guide branch pipe.

[0011] Optionally, a plurality of air guide holes are provided and are equidistantly distributed on the surface of the air guide branch pipe, and the air guide holes are strip-shaped.

[0012] Optionally, the bracket consists of longitudinal rods and transverse rods, and a placement frame is installed on the bracket, with through holes on the side wall of the placement frame.

[0013] Optionally, the controller is equipped with a control button for setting the wind speed and a display screen for displaying the current wind speed.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up a structure that combines the main air duct, connecting pipe and branch air duct, precise air supply can be achieved for shelves of different heights. This avoids the problem of excessive air volume in the upper layer of ice cubes and insufficient air volume in the lower layer caused by traditional fixed air supply from the top or side wall. It also prevents excessive moisture loss in the upper layer of ice cubes, incomplete drainage or low pre-cooling efficiency in the lower layer of ice cubes, and ensures that each layer of ice cubes can obtain the appropriate air volume, thus ensuring consistent production quality.

[0016] 2. By setting up a structure that combines the angle adjustment component with the wind speed control component, the wind speed and direction can be flexibly adjusted to meet the production needs of persimmons in multiple stages. In the drying stage after washing, the opening degree of the electric air valve can be reduced and the angle of the air guide branch pipe can be adjusted to achieve low wind speed and wide coverage ventilation. In the pre-cooling stage, the opening degree of the electric air valve can be increased and the angle of the air guide branch pipe can be set in a specific direction to achieve medium to high wind speed and directional cooling ventilation, thus solving the shortcomings of the existing device that cannot flexibly adapt to different stages.

[0017] 3. By setting up an electric air valve and connecting it to the corresponding layered air ducts, the wind speed of a single or local air duct can be independently controlled. There is no need to increase the overall fan power to meet the ventilation needs of the lower layer of ice, reducing unnecessary energy consumption, meeting energy conservation and environmental protection requirements, and reducing energy cost waste in the production process.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Example 1

[0031] Please see Figure 1-6As shown, this embodiment provides an indoor ventilation system for persimmon production, including: a support frame, a main air guide pipe 2, branch air guide pipes 5, a wind speed control component, and an angle adjustment component; the main air guide pipe 2 is horizontally arranged on the side wall or top of the persimmon production room, with one end connected to the air outlet of the fan of the production room ventilation system, and a plurality of connecting pipe interfaces 14 are opened along the length of the pipe body; each layer of the support frame is connected to two sides of a connecting block 6, and each layer of connecting blocks 6 is connected to a branch air guide pipe 5 through an angle adjustment component, and the surface of the branch air guide pipe 5 is provided with air guide holes 8, and the main air guide pipe 2 and the connecting block 6 are connected to a connecting pipe 14; the wind speed control component includes an electric air valve 3 and a controller 4, the electric air valve 3 is installed at the connection between the connecting pipe 14 and the branch air guide pipe 5, and the electric air valve 3 and the controller 4 are electrically connected.

[0032] The bracket serves as the foundation for system installation and employs a layered design (suitable for production scenarios with multiple layers of persimmons). Connecting blocks 6 on both sides provide stable support for the branch air ducts 5, ensuring precise positioning of the multi-layered ventilation structure. The main air duct 2 is installed horizontally on the side wall or ceiling of the production room, with one end connected to the fan outlet to receive airflow. Several connecting pipes 14 on the duct body allow for airflow distribution, providing uniform air supply to the multi-layered branch air ducts 5. The branch air ducts 5 are connected to the connecting pipes 14 of the main air duct 2 via connecting blocks 6. Air guide holes 8 on the surface evenly diffuse the airflow to the persimmon storage area. The angle adjustment component between the branch air duct and the connecting blocks 6 allows for flexible adjustment of the airflow direction and speed control. The control component consists of an electric air valve 3 and a controller 4. The electric air valve 3 is installed at the connection between the connecting pipe 14 and the air guide branch pipe 5. The controller 4 can precisely adjust the airflow of a single air guide branch pipe 5. The controller 4 supports manual setting or automatic control in conjunction with sensors to realize digital control of wind speed. After the airflow generated by the fan enters the main air guide pipe 2, it is distributed to the air guide branch pipes 5 of each layer through the interface of the connecting pipe 14. The controller 4 adjusts the opening and closing degree of the electric air valve 3 according to the production process requirements to control the wind speed of each branch pipe. At the same time, the air delivery direction of the air guide branch pipe 5 is set by the angle adjustment component. The airflow is blown out evenly through the air guide hole 8 to form a precise ventilation environment covering the entire production area.

[0033] Example 2

[0034] Please see Figure 1-6 As shown, in this embodiment, the angle adjustment component includes a connecting ring 9 and a connecting sleeve 7. The connecting sleeve 7 is connected to the side wall of the connecting block 6 and is threadedly connected to the air guide branch pipe 5. The connecting ring 9 is located on the surface of the air guide branch pipe 5 and is fixedly connected to the surface of the air guide branch pipe 5. It is located at the end where the air guide branch pipe 5 is connected to the connecting sleeve 7. A connecting channel 10 is provided in the connecting block 6. One end of the connecting channel 10 is connected to the connecting pipe 14, and the other end passes through the connecting sleeve 7 and is connected to the air guide branch pipe 5.

[0035] The connecting sleeve 7 is fixed to the side wall of the connecting block 6 and is threaded to the air duct branch pipe 5. The connecting ring 9 is fixed to one end of the air duct branch pipe 5 near the connecting sleeve 7 and has a friction layer on its surface. The connecting block 6 has a connecting channel 10 inside, one end of which connects to the connecting pipe 14, and the other end passes through the connecting sleeve 7 and communicates with the air duct branch pipe 5. The connecting ring 9 has a friction layer on its surface. There is a gap between the air duct branch pipe 5 and the connecting sleeve 7. When it is necessary to adjust the angle of the air duct branch pipe 5, the connecting ring 9 is rotated with the help of the friction layer on the surface of the connecting ring 9 (to increase the friction between the hand and the connecting ring 9 and avoid slippage). This causes the air duct branch pipe 5 to rotate along the thread of the connecting sleeve 7, thereby changing the tilt angle of the air duct branch pipe 5. The connecting channel 10 inside the connecting block 6 always keeps the airflow between the connecting pipe 14 and the air duct branch pipe 5 connected, ensuring that ventilation is not interrupted during the angle adjustment process. The gap between the air duct branch pipe 5 and the connecting sleeve 7 allows for easy rotation of the air duct branch pipe 5 to achieve angle adjustment and prevents the air duct branch pipe 5 from locking up.

[0036] Example 3

[0037] Please see Figure 1-6 As shown, in this embodiment, there are several air guide holes 8, which are equidistantly distributed on the surface of the air guide branch pipe 5, and the air guide holes 8 are strip-shaped.

[0038] After the airflow delivered by the main air duct 2 enters the branch air duct 5, it is evenly discharged through the equally spaced strip-shaped air guide holes 8. The design of the strip-shaped holes can increase the single air outlet area, and the equal distribution can ensure that the output intensity of the airflow is consistent along the length of the branch air duct 5, avoiding excessively strong or weak airflow in local areas. Compared with circular holes, the strip-shaped air guide holes 8 have a gentler air outlet (the airflow diffusion range of the strip-shaped holes is wider and the wind pressure per unit area is lower), which can further reduce the impact of the airflow on the persimmon peel, while increasing the air outlet area and improving the ventilation volume per unit time.

[0039] The bracket consists of a longitudinal rod 1 and a transverse rod 11, and a placement frame 12 is installed on the bracket. The side wall of the placement frame 12 has a through hole 13.

[0040] The longitudinal rod 1 and the transverse rod 11 are combined to form a stable multi-layer frame. The spacing of the transverse rod 11 can be flexibly adjusted according to the production scale of persimmons (changing the number of layers of the placement frame 12). After the persimmons are placed in the placement frame 12, the airflow blown out by the air guide branch pipe 5 can enter the frame through the through hole 13 on the side wall of the placement frame 12, realizing all-round enveloping ventilation of the persimmons and avoiding the airflow being blocked by the placement frame 12, resulting in ventilation dead corners.

[0041] The controller 4 is equipped with a control button 16 for setting the wind speed and a display screen 15 for displaying the current wind speed.

[0042] The operator sets the target wind speed through the control button 16. The controller 4 transmits the command to the electric air valve 3 and adjusts the valve opening to achieve the set wind speed. The display screen 15 displays the current actual wind speed, which allows the operator to intuitively monitor whether the wind speed meets the process requirements. If there is a deviation, it can be corrected in time through the control button 16.

[0043] Working principle:

[0044] After the system is started, the airflow generated by the fan is first delivered to the horizontally installed air guide main pipe 2. The main pipe distributes the airflow to the connecting pipes 14 of each layer through the pipe body connecting pipe 14 interface, and then sends it into the air guide branch pipe 5 through the connecting channel 10 in the bracket connecting block 6.

[0045] The angle adjustment component enables airflow directional control: the connecting sleeve 7 on the side wall of the connecting block 6 is threadedly connected to the air guide branch pipe 5, and there is a gap between the two. The operator can rotate the branch pipe with the connecting ring 9 with friction layer at the end of the air guide branch pipe 5 to adjust the tilt angle along the thread (such as turning 45° downwards from horizontal). During adjustment, the connecting channel 10 keeps the airflow connected and does not interrupt ventilation.

[0046] The strip-shaped air guide holes 8 evenly distributed on the surface of the air guide branch pipe 5 allow the airflow to be discharged evenly, which not only avoids "stronger airflow near the front and weaker airflow far away", but also increases the air outlet area and reduces the wind pressure due to the strip-shaped holes, thus preventing damage to the persimmon peel.

[0047] The support consists of longitudinal rod 1 and transverse rod 11, and the layer height can be flexibly adjusted to adapt to different production scales. The through holes 13 on the side wall of the frame 12 are placed on it, so that airflow can penetrate the frame and form all-round ventilation of "external surround + internal penetration" for the internal ice cubes, solving the problem of traditional ventilation dead corners.

[0048] The wind speed control component ensures precise ventilation: the operator sets the wind speed through the button on the controller 4, the controller 4 instructs the electric air valve 3 (installed between the connecting pipe 14 and the branch pipe) to adjust the opening degree to control the flow rate, and the display screen 15 displays the wind speed in real time, which is convenient for timely calibration of deviations.
