Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a portable food air separator. Background Technology

[0002] In the food processing industry, air separators, as core equipment that utilizes differences in the aerodynamic properties of materials to achieve separation, are widely used in scenarios such as nut screening and dried goods grading. However, traditional air separators have significant limitations in structural design.

[0003] These air separators typically employ a monolithic structure, with core components such as the fan and collection device assembled using permanent connections like welding and bolting, making disassembly and reassembly difficult. This results in bulky, heavy equipment that, even with simplified handling mechanisms, cannot meet the flexible usage needs of small food processing workshops or mobile food inspection points. Especially when food sorting and processing requires relocating the equipment across multiple locations, the monolithic structure of the air separator makes rapid disassembly and transportation difficult, leading to cumbersome redeployment processes. This increases labor and logistics costs and limits the equipment's efficiency and application scope. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable food air separator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable food air separator includes an air separator box with multiple sorting slots through a first opening, a mounting block through a second opening, a fan assembly on the mounting block via a throttle, a storage trough on the air separator box via a support mechanism, a discharge pipe on the storage trough, a third opening corresponding to the discharge pipe, a mounting frame on the storage trough via a mounting slot, a pressing groove on the mounting frame, a positioning block within the pressing groove via a pressing mechanism, a positioning hole on the storage trough, and a screw rotatably mounted between two mounting frames. A pusher plate is threaded onto the screw, and the screw is connected to the throttle via a rotating mechanism.

[0007] Preferably, the support mechanism includes a support rod fixedly disposed at the bottom of the storage tank, and the upper surface of the air separator is provided with a support groove corresponding to the support rod.

[0008] Preferably, the extrusion mechanism includes a spring disposed in the extrusion groove, with both ends of the spring connected to the bottom wall of the extrusion groove and the outer wall of the positioning block, respectively.

[0009] Preferably, the rotating mechanism includes pulleys fixedly mounted on the throttle and the screw, and the two pulleys are connected by a connecting belt.

[0010] Preferably, a limiting rod is fixed between the two mounting brackets, and the limiting rod is parallel to the screw and slides through the pusher plate.

[0011] Preferably, the vertical cross-sectional view of the mounting slot and the mounting bracket is L-shaped, and the sorting slot is provided with a handle for easy gripping.

[0012] The beneficial effects of this utility model are:

[0013] 1. The device adopts a modular design. The sorting trough can be pulled out and detached, the connecting belt can be disassembled to disconnect the linkage between the throttle and the screw, the lower positioning block can release the limit of the mounting frame, and the storage trough can also be separated from the air separator by lifting it up. Each component can be disassembled, effectively dispersing the weight and volume, greatly reducing the difficulty of handling, and meeting the needs of outdoor operation and multi-location use.

[0014] 2. By using a single throttle and the transmission of the pulley and connecting belt, the fan assembly and screw can be rotated, realizing material pushing and air separation, reducing operation steps and improving food air separation efficiency.

[0015] 3. The support rod and support groove cooperate to firmly connect the storage tank and the air classifier box with greater friction; the spring pushes the positioning block into the positioning hole to ensure the stability of the mounting frame; the limit rod restrains the push plate to prevent it from rotating with the screw, ensuring the accuracy of material pushing and ensuring the stable operation of the equipment.

[0016] 4. Connecting belts and other easily damaged parts are easy to disassemble and replace. After disassembly, components such as sorting troughs and mounting racks are easy to clean of residual materials inside, reducing equipment maintenance costs and extending service life.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A portable food air separator includes an air separator box 1, which has multiple sorting slots 2 through a first opening. The air separator box 1 has a mounting block 3 through a second opening. The mounting block 3 has a fan assembly 15 through a throttle 4. The fan assembly 15 can be multiple fan blades directly welded onto the throttle 4.

[0024] The air classifier 1 is provided with a storage tank 5 via a support mechanism. The storage tank 5 is provided with a discharge pipe 14. The air classifier 1 is provided with a third opening corresponding to the discharge pipe 14. The storage tank 5 is provided with a mounting bracket 7 via a mounting groove 6. The mounting bracket 7 is provided with a pressing groove 16. The pressing groove 16 is provided with a positioning block 17 via a pressing mechanism. The storage tank 5 is provided with a positioning hole 13. A screw 8 is rotatably provided between the two mounting brackets 7. A pusher plate 10 is threaded on the screw 8. The screw 8 is connected to the handle 4 via a rotating mechanism.

[0025] The support mechanism includes a support rod 19 fixedly installed at the bottom of the storage tank 5, and a support groove 20 corresponding to the support rod 19 is provided on the upper surface of the air classifier box 1. The support rod 19 is located in the support groove 20, which realizes the convenient assembly and disassembly of the storage tank 5 relative to the air classifier box 1. The outer wall of the support rod 19 has a large friction, and it requires force to insert it into the support groove 20.

[0026] The extrusion mechanism includes a spring 18 disposed within the extrusion groove 16, with both ends of the spring 18 connected to the bottom wall of the extrusion groove 16 and the outer wall of the positioning block 17, respectively. The elastic potential energy provided by the spring 18 enables the positioning block 17 to be pushed upward, ensuring that after it is pushed into the positioning hole 13, the mounting bracket 7 is stably installed within the mounting groove 6.

[0027] The rotating mechanism includes pulleys 11 fixedly mounted on the throttle 4 and the screw 8, and the two pulleys 11 are connected by a connecting belt 12. The connecting belt 12 and the pulleys 11 enable the rotation of the throttle 4 and the screw 8. The connecting belt 12 can be replaced in time when it becomes loose to ensure a tight tension.

[0028] A limiting rod 9 is fixed between the two mounting brackets 7. The limiting rod 9 is parallel to the screw 8 and slides through the pusher plate 10. The limiting rod 9 limits the pusher plate 10 and prevents it from rotating with the screw 8.

[0029] Both the mounting slot 6 and the mounting bracket 7 have an L-shaped vertical cross-section, and the sorting slot 2 is equipped with a handle for easy gripping. This L-shaped design limits the mounting bracket 7's installation relative to the mounting slot 6, allowing the mounting bracket 7 to be moved horizontally and disassembled relative to the mounting slot 6.

[0030] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0031] In use, the food is placed in the storage tank 5. The handle 4 is then gripped and rotated. The rotating mechanism, consisting of the pulley 11 and the connecting belt 12, causes the screw 8 to rotate as well. As the screw 8 rotates, the threaded pusher plate 10, constrained by the limiting rod 9 (to prevent rotation), moves horizontally along the axis of the screw 8, pushing the material in the storage tank 5 towards the discharge pipe 14. The material enters the air separator 1 through the third opening of the discharge pipe 14. At this time, the fan assembly 15 rotates under the drive of the handle 4, blowing out a horizontal airflow. The material is then classified by the airflow within the air separator 1.

[0032] In this design, the sorting trough 2 can be pulled out and detached from the air separator box 1. The connecting belt 12 can be detached from the connection between the throttle 4 and the screw 8. Pressing down on the positioning block 17 in the positioning hole 13 can release the limit of the mounting frame 7. Then, the mounting frame 7 can be moved to separate it from the storage trough 5. Finally, by grasping the storage trough 5 and lifting it up, it can be detached from the air separator box 1. The device can be flexibly installed and easily disassembled among its multiple components, and its mass and volume can be dispersed, thereby achieving the purpose of easy portability.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
