Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of auxiliary devices for drying equipment, and specifically relates to a flip-plate box for drying equipment. Background Technology
[0002] Existing nut drying equipment mostly adopts a multi-layer box structure, with nuts being heated and dried gradually in different layers. Common flip-plate drying equipment typically uses mechanically driven flippers to achieve material turning and layer transfer, preventing nut accumulation and improving heating uniformity. However, in existing technologies, the flipper drive relies on mechanical transmission. Traditional flipper mechanisms mostly use motors, sprockets, or connecting rods to drive the flipper action, resulting in rapid mechanical wear, frequent maintenance, and easy jamming or damage when the turning is obstructed. Although the drying box is generally equipped with a hot air inlet device, the hot air is mostly distributed evenly or flows in unidirectionally, leading to excessive air velocity in some areas and insufficient air velocity in others, resulting in uneven drying. In existing flip-plate boxes, the flipping action and the air distribution system work independently, and the flipping action cannot be adaptively triggered according to the airflow state, making it difficult to achieve coupled optimization of drying efficiency and turning uniformity.
[0003] Therefore, a more rationally structured flap box is needed that can drive the flapping action through airflow and form a linkage with the layered air distribution to solve the problems of stiff flapping action, insufficient air distribution uniformity, and lack of feedback control in the existing equipment. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a flip-plate box for drying equipment, which can solve the problems of stiff flip-plate movement, insufficient air distribution uniformity and lack of feedback control in the existing equipment.
[0005] The technical solution adopted by this utility model is a flip-plate box for a drying equipment, including a flip-plate box. Multiple flip-plate assemblies are hinged along the height direction inside the flip-plate box. A main air supply cavity is connected to the bottom of the flip-plate box. The main air supply cavity is connected to multiple annular distributed air cavities. Each flip-plate assembly corresponds to each annular distributed air cavity. The annular distributed air cavities are connected to the flip-plate box through guide holes. An airflow driving assembly is provided below the flip-plate assembly. A guide and throttling assembly is provided at the outlet of the annular distributed air cavity. A detection and linkage assembly is provided on the flip-plate box. The detection and linkage assembly includes a wind pressure sensor and a wind speed sensor located at the end of the annular distributed air cavity, and an angle sensor installed on the airflow driving assembly.
[0006] The present invention is further characterized in that, The flap assembly includes a flap body, which is connected to the flap box via a hinge shaft. A return torsion spring is sleeved on the hinge shaft. A limit stop is provided below the flap body, and the limit stop is located on the opposite side of the flap body from the hinge shaft. A turbulence rib is provided on the side of the flap body near the hinge shaft.
[0007] The airflow drive assembly includes a pneumatic excitation chamber and a jet nozzle array connected to the main air supply chamber, with the jet nozzle array located on both sides of the limiting block.
[0008] A one-way check valve is provided between the annular distribution air cavity and the pneumatic excitation cavity.
[0009] The flow guiding and throttling assembly includes an adjustable-angle flow guide plate and a throttling slide valve.
[0010] The beneficial effects of this utility model are: (1) This utility model provides a flip-plate box for drying equipment. By setting a pneumatic excitation chamber and a jet nozzle under the flip plate, the airflow is directly applied to the flip plate, so that the flip plate can be flipped without complex mechanical transmission, thereby reducing the wear and failure rate of the mechanism.
[0011] (2) This utility model provides a flip plate in the flip plate box of a drying equipment, which realizes reset and angle control through return torsion spring and limit block, so that the action is stable and avoids excessive flipping or loss of control. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:
[0015] like Figure 1-4 As shown, this utility model discloses a flip-plate box for a drying equipment, comprising: a flip-plate box 1, the overall structure of which adopts a vertical box design; multiple flip-plate components 2 are hinged sequentially along the height direction inside the flip-plate box 1; the flip-plate components 2 can achieve layered flipping under controlled drive, so that the material falls layer by layer and flips continuously during the drying process, thereby effectively avoiding uneven heating caused by local accumulation; the bottom end of the flip-plate box 1 is connected to a main air supply cavity 3; after the main air supply cavity 3 is connected to an external heat source system, it can evenly distribute hot air to each layer; the main air supply cavity 3 is connected to multiple annular distribution air cavities 4, which correspond to each layer of flip-plate components 2; each annular distribution air cavity 4 is connected to the inside of the flip-plate box 1 through a guide hole, so that the hot air can directly act on the material area of that layer, thereby achieving directional heating and efficient drying; Below each layer of the flip-plate assembly 2, airflow drive components 5 are evenly distributed. The airflow drive components 5 can release air under the action of external control signals, causing the flip-plate assembly 2 to flip. The outlet of the annular distribution air cavity 4 is further provided with a flow guide and throttling component, which is used to flexibly adjust the air outlet direction and air volume according to different material thicknesses and moisture conditions, so as to make the hot air supply of different layers more precise and avoid drying deviations caused by excessive or insufficient air volume in some areas. The outer wall of the flip-plate box 1 is equipped with a detection and linkage component, which includes a wind pressure sensor and a wind speed sensor arranged at the end of the annular distribution air cavity 4, used to detect the pressure and flow velocity parameters of the hot air in real time during the conveying and distribution process, and feed the detection data back to the control system. An angle sensor is also installed on the airflow drive component 5 to monitor the action angle and displacement of the flip-plate assembly 2 during the flipping process, so as to promptly adjust the airflow drive and air supply parameters when the flip-plate is not flipped in place or the action is abnormal, thereby realizing dynamic monitoring and precise control of the entire material drying process.
[0016] The flip plate assembly 2 includes a flip plate body 201, which is rotatably connected to the inner wall of the flip plate box 1 via a hinge shaft 202. A return torsion spring 203 is sleeved on the outer periphery of the hinge shaft 202. The return torsion spring 203 can provide a reset torque after the flip plate body 201 is flipped, so that the flip plate body 201 can quickly return to the initial position, ensuring the continuity and reliability of the next round of flipping action. A limit stop 204 is provided below the flap body 201. The limit stop 204 and the hinge shaft 202 are located on the opposite side of the flap body 201. The function of the limit stop 204 is to provide physical limit during the flap flipping or returning process, so as to avoid the flap angle being too large or the reset not being in place, thereby ensuring the accuracy and stability of the flap action. The surface of the flap body 201 near the hinge shaft 202 is also provided with a turbulence rib. The turbulence rib can break the straight line of airflow when hot air passes through the flap body 201, generate a turbulence effect, thereby enhancing the airflow effect and making the flap flip.
[0017] The airflow drive assembly 5 includes a pneumatic excitation chamber and a jet nozzle array 501 connected to the main air supply chamber 3. The pneumatic excitation chamber can concentrate and collect high-pressure airflow to form a stable excitation air source. The jet nozzle array 501 is arranged along the transverse area below the flap assembly 2 to form a stable and directional thrust airflow. The jet nozzle array 501 is arranged on both sides of the limiting block 204.
[0018] A one-way check valve is provided between the annular distribution air chamber 4 and the pneumatic excitation chamber.
[0019] The flow guiding and throttling assembly includes an adjustable-angle flow guide plate and a throttling slide valve.
[0020] Working principle: The main air supply chamber 3 is connected to an external heat source system, and high-temperature hot air is evenly delivered to the annular distribution air chambers 4 of each layer. Then, through the guide holes, it acts on the material area in the corresponding layer of the flap assembly 2, realizing layer-by-layer directional heating. Each layer of flap assembly 2 is controlled to flip under the action of the airflow drive component 5. The material falls to the next layer in sequence with the flipping action, so that it is continuously flipped and dispersed in the multi-layer cycle, avoiding accumulation and ensuring uniform heating. The flap body 201 quickly returns to its original state under the reset action of the return torsion spring 203, preparing for the next round of flipping. The limit block 2 04 provides physical limits to ensure precise flipping angles, while the turbulence ribs create disturbances when hot air flows through, enhancing the airflow. The pneumatic excitation chamber in the airflow drive component 5 concentrates high-pressure airflow and forms directional thrust on both sides of the limit block 204 through the jet nozzle 501. The one-way check valve between the annular distribution air chamber 4 and the pneumatic excitation chamber prevents backflow and ensures stable system operation. The guide plate and throttling slide valve in the flow guiding and throttling component flexibly adjust the airflow direction and volume according to different material thicknesses and moisture contents, achieving precise drying control for different levels of materials. The entire system combines multi-layer flipping, airflow drive, and dynamic control to achieve top-down graded circulation drying and uniform heating throughout the process, thereby improving drying efficiency and thermal energy utilization.
