Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, in particular to a convenient air inlet device for an air inlet chamber. Background Art

[0002] The slow cooling section of the grain dryer is a key link in the drying process. Its main function is to keep the grain warm under a specific temperature and humidity environment to ensure that the temperature and moisture distribution of the grain are balanced. This link is designed to prevent the rapid shrinkage of the grain due to rapid cooling and promote the uniform distribution of moisture inside the grain, thereby effectively avoiding quality problems such as mildew and germination that may occur during subsequent storage and processing.

[0003] The operating mechanism of the slow recovery section mainly relies on the inhalation of external air, and removes excess moisture from the grain by lowering the temperature in the slow recovery section. Specifically, the slow recovery section adopts a negative pressure ventilation method, that is, the outside air is introduced into the slow recovery section through the air inlet chamber. In order to optimize the above ventilation process, the utility model provides a convenient air inlet device for the air inlet chamber to achieve the air replenishment effect and significantly improve the efficiency of negative pressure ventilation. Utility Model Content

The above-mentioned structure optimizes the negative pressure ventilation process in the air intake chamber, and by controlling the make-up air volume, meets the specific requirements of the slow recovery section for the make-up air volume under different working conditions, thereby ensuring that the gas inside the air intake chamber can quickly and effectively enter the slow recovery section, thereby significantly improving the overall effect of the negative pressure ventilation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts a convenient air inlet device for the air inlet chamber, including an air inlet chamber installed at the position of the slow-release section, the air inlet chamber has an air inlet path in a negative pressure state and is connected to the slow-release section, the air suction device is installed on the opposite side of the air inlet chamber and provides negative pressure for the air inlet chamber, the air inlet is installed on the side wall of the above-mentioned air inlet chamber, the air inlet is located on the above-mentioned air inlet path to connect the outside with the air inlet path, the baffle plate is coaxially arranged with the air inlet and the baffle plate is rotatably installed on the side wall of the air inlet chamber, the above-mentioned air inlet is located on the rotation path of the above-mentioned baffle plate, and the shielding action or ventilation action of the above-mentioned air inlet is realized by the rotation action of the above-mentioned baffle plate, and the driving component provides power to the baffle plate and drives the baffle plate to rotate.

[0006] The above structure cleverly combines the air inlet and the rotatable baffle to achieve an efficient air supply function. By accurately adjusting the position of the baffle to control the air supply volume, the specific air supply volume requirements of the slow recovery section under different working conditions are met, ensuring that the gas inside the air inlet chamber can quickly and effectively enter the slow recovery section, significantly improving the overall effect of negative pressure ventilation, and then optimizing the slow recovery process, improving the slow recovery efficiency, and ultimately ensuring the quality of grain slow recovery.

[0007] As a further optimization of the above scheme, the air inlet includes three coaxially arranged fan-shaped openings, and the shielding plate has a connecting opening that is a matching structure with the fan-shaped openings. When the fan-shaped openings are aligned with the connecting openings, the outside world and the air inlet path are ventilated, and after the fan-shaped openings are aligned with the rest of the shielding plate, the outside world and the air inlet path are closed. The above structure achieves more precise air intake control. When the fan-shaped openings are aligned with the connecting openings, the air inlet path is fully opened to ensure maximum ventilation; when they are aligned with the rest of the shielding plate, they are fully closed to prevent air from entering the ventilation path from the air inlet.

[0008] As a further optimization of the above-mentioned scheme, the above-mentioned driving component includes a connecting rod connected to the baffle plate, a limiting groove is opened on the side wall of the air inlet chamber, one end of the connecting rod passes through the limiting groove and is connected to a driving handle, and the driving handle drives the connecting rod to move along the limiting groove and realizes the rotation action of the baffle plate to complete the blocking action or ventilation action of the above-mentioned air inlet. The number of air inlets on the same vertical plane is at least two, and each connecting part on the same vertical plane is fixed on the above-mentioned driving handle to drive the various connecting parts on the same vertical plane to move synchronously through the action of the above-mentioned driving handle.

[0009] The above structure can realize rapid adjustment of the air intake volume through simple manual operation, thus improving the convenience and efficiency of operation. At the same time, the design of multiple air inlets further enhances the ventilation effect, and uses a driving handle for synchronous control, which simplifies the operation process and improves work efficiency.

[0010] As a further optimization of the above scheme, an inclined plate is also fixed on the side wall of the air inlet chamber, and the inclined plate is located on the downward movement path of the driving handle. The driving handle is provided with a number of slots from top to bottom that are matched with the inclined plate. The driving handle and the connecting piece are slidably matched to enable the driving handle to move in a straight line along the connecting piece. The movement of the driving handle approaching along the connecting piece drives the inclined plate and the slot to realize a snap-fit ​​action to locate the position of the driving handle. The connecting rod is provided with a limiter and the limiter is located on the outward movement path of the driving handle to limit the moving distance of the driving handle.

[0011] The design of the inclined plate and the card slot in the above structure provides stable positioning for the driving handle, prevents changes in the air intake volume due to misoperation or external force, and ensures the stability of the ventilation system. The design of the limiter ensures the position of the driving handle and prevents the driving handle from being detached from the connecting rod due to excessive operation.

[0025] Please refer to the instruction manual Figure 1-3 The utility model provides an embodiment of a convenient air intake device for an air intake chamber. Specifically, the device is installed in a slow-release section 1, and the interior of the air intake chamber 2 is designed to be in a negative pressure state, and forms an air intake path connected with the slow-release section 1. The air suction device 3 is installed on the opposite side of the air intake chamber 2 to provide the required negative pressure for the air intake chamber 2. An air inlet 4 is installed on the side wall of the air intake chamber 2, and the air inlet 4 connects the outside with the air intake path. A baffle plate 5 coaxially arranged with the air inlet 4 is rotatably installed on the side wall of the air intake chamber 2, and the air inlet 4 can be blocked or opened by its rotation. In addition, a driving component 6 is also provided to provide rotational power for the baffle plate 5.

[0026] The above structure integrates the design of the air inlet 4 and the rotating baffle plate 5 to achieve high efficiency of the air supply function. By accurately adjusting the position of the baffle plate 5, the air supply volume can be controlled to meet the air supply needs of the slow recovery section 1 under different working conditions. It ensures that the gas inside the air inlet chamber 2 can quickly and effectively enter the slow recovery section 1, and also significantly improves the effect of negative pressure ventilation, thereby optimizing the slow recovery process, improving the slow recovery efficiency, and ensuring the quality of grain slow recovery.

[0027] In order to further improve the accuracy of air intake, in this embodiment, the air inlet 4 is composed of three coaxially arranged fan-shaped openings 7, and the shielding plate 5 is provided with a connecting opening 8 that matches these fan-shaped openings 7. When the fan-shaped openings 7 are aligned with the connecting openings 8, the air intake path is completely open to ensure the maximum ventilation volume; and when the fan-shaped openings 7 are aligned with other parts of the shielding plate 5, the air intake path is completely closed to prevent any unnecessary air from entering the air intake chamber 2 from the air inlet 4.

[0028] In order to improve the convenience and efficiency of operation, the driving component 6 includes a connecting rod 9 connected to the shielding plate 5. A limiting groove 10 is provided on the side wall of the air inlet chamber 2, and one end of the connecting rod 9 passes through the limiting groove 10 and is connected to a driving handle 11. Thus, the air intake volume can be quickly adjusted through simple manual operation.

[0029] Furthermore, the number of air inlets 4 on the same vertical plane is at least two, and each connecting part on the same vertical plane is fixed on the above-mentioned driving handle 11. Therefore, multiple air inlets 4 on the same vertical plane can be synchronously controlled by one driving handle 11, which simplifies the operation process and improves work efficiency.

[0030] In order to enhance the stability of the system, an inclined plate 12 is fixed to the side wall of the air inlet chamber 2, and the inclined plate 12 cooperates with the slot 13 on the driving handle 11 to provide stable positioning for the driving handle 11. In addition, a limiter 14 is provided on the connecting rod 9 to ensure that the driving handle 11 will not be separated from the connecting rod 9 due to excessive operation. These designs together ensure the stability and safety of the ventilation system.

[0031] The convenient air inlet device for the air inlet chamber provided in this embodiment has a ventilation action working process as follows:

[0032] Step 1: Initial state

[0033] The interior of the air inlet chamber 2 is in a negative pressure state and is connected to the slow-release section 1 to form an air inlet path.

[0034] The air inlet 4 (composed of three coaxially arranged fan-shaped openings 7) is located on the side wall of the air inlet chamber 2, connecting the outside with the air inlet path.

[0035] The shielding plate 5 is coaxially arranged with the air inlet 4 and is rotatably mounted on the side wall of the air inlet chamber 2 and may be in any rotational position.

[0036] Step 2: Prepare for ventilation

[0037] The operator checks the air suction device 3 to ensure that it works normally and provides the required negative pressure for the air inlet chamber 2.

[0038] The operator observes the positional relationship between the shielding plate 5 and the air inlet 4 to determine the current ventilation status.

[0039] Step 3: Adjust ventilation

[0040] The operator adjusts the position of the shielding plate 5 by driving the component 6 (the connecting rod 9 and the driving handle 11 ).

[0041] The operator holds the driving handle 11 .

[0042] The operator moves the driving handle 11 to drive the shielding plate 5 to rotate through the connecting rod 9 .

[0043] During the adjustment process, the connection opening 8 on the shielding plate 5 will gradually align with or stagger with the fan-shaped opening 7 of the air inlet 4, thereby controlling the ventilation volume.

[0044] Step 4: Completely open or close the air inlet 4

[0045] When the connection opening 8 on the shielding plate 5 is completely aligned with the fan-shaped opening 7 of the air inlet 4, the air inlet path is completely open to ensure maximum ventilation.

[0046] When the shielding plate 5 rotates to completely block the air inlet 4, the air inlet path is closed, preventing outside air from entering.

[0047] Step 5: Stabilization and Fixation

[0048] After adjusting the required ventilation volume, the operator can release the driving handle 11.

[0049] The inclined plate 12 on the side wall of the air inlet chamber 2 cooperates with the clamping groove 13 on the driving handle 11 to provide stable positioning for the driving handle 11 and ensure that the ventilation volume remains stable.

[0050] Step 6: Monitor and adjust

[0051] During the ventilation process, the operator can regularly check the ventilation status to ensure that the ventilation volume meets the requirements of the slow recovery stage 1.

[0052] If you need to adjust the ventilation rate, repeat steps 3 to 5.

[0053] Through the above steps, the operator can accurately control the ventilation volume of the air inlet chamber 2 to meet the air supply demand of the slow recovery section 1 under different working conditions, thereby significantly improving the ventilation efficiency, optimizing the slow recovery process, improving the slow recovery efficiency, and ensuring the quality of grain slow recovery.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
