DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0024] The embodiments of the present application provide a dust removal device for grain storage, which can solve the problem that the existing grain dust removal mechanism in the related art has poor effect and limited dust removal effect on impurities inside the grain.

[0025] Please refer to Figures 1-3 A dust removal device for grain storage comprises a frame 1, wherein a cylinder 2 is arranged on the frame 1, the cylinder 2 has a chamber for accommodating grain inside, a stirrer 3 is arranged inside the cylinder 2, the stirrer 3 is used for turning the grain inside the chamber, and a dust suction mechanism 4 is arranged on the cylinder 2; the dust suction mechanism 4 comprises a plurality of dust suction pipes 41 arranged on the cylinder 2, an air extractor 42 is arranged inside each of the dust suction pipes 41, a conveying pipe 43 is connected between the upper ends of the plurality of dust suction pipes 41, and a bag dust collector 44 is arranged at one end of the conveying pipe 43.

[0026] Firstly, the grain is loaded into the chamber inside the cylinder 2 through the feeding hopper 5. The chamber provides a closed and turnable environment for the grain, facilitating subsequent dust removal treatment.

[0027] When the grain is loaded, the stirrer 3 is started. The stirrer 3 comprises a rotating shaft 31 rotatingly arranged inside the cylinder 2 and a plurality of stirring shovels 32 arranged in a ring shape. The driving part 33 drives the rotating shaft 31 to rotate through the driving motor 331 and the pulley 332, and then the stirring shovels 32 turn the grain inside the chamber. The purpose of this step is to expose the impurities and pests inside the grain, preparing for subsequent dust suction.

[0028] The dust suction mechanism 4 starts working while the stirring mechanism 3 is stirring. Multiple suction pipes 41 are evenly distributed on the cylinder 2. The suction fans 42 inside the suction pipes 41 generate suction force, which sucks the exposed impurities, pests, and part of the dust into the suction pipes 41. These sucked impurities and dust are then transported to the bag filter 44 through the conveying pipes 43.

[0029] The bag filter 44 is a high-efficiency dust removal device that can filter and purify the transported impurities and dust. The air after being treated by the bag filter 44 becomes clean and can be discharged into the atmosphere, while the impurities and dust are collected in the filter bag of the bag filter 44 and can be cleaned regularly.

[0030] By stirring the grain with the stirring mechanism 3 to expose the internal impurities and pests, and combining the high-efficiency dust suction capability of the dust suction mechanism 4, deep dust removal of the grain can be achieved, greatly improving the dust removal effect. The dust removal device has a relatively simple structure, mainly composed of the frame 1, the cylinder 2, the stirring mechanism 3, and the dust suction mechanism 4, etc., which is easy to manufacture, install, and maintain. At the same time, the operation process is simple and clear, and only needs to start the stirring mechanism 3 and the dust suction mechanism 4 to complete the dust removal work, greatly reducing the operation difficulty and labor intensity.

[0031] In the present embodiment, the cylinder 1 is provided with a feed hopper 5 above it, and a discharge hopper 6 at the bottom, which are located on both sides of the cylinder 1.

[0032] The feed hopper 5 is located above the cylinder 1, and its main function is to serve as the entrance for the grain to enter the chamber of the cylinder 2. During operation, the grain is continuously or intermittently fed into the cylinder through the feed hopper 5, providing sufficient raw materials for subsequent stirring and dust removal treatment.

[0033] The discharge hopper 6 is located at the bottom of the cylinder 1, and its main function is to serve as the outlet for the grain after dust removal treatment. After dust removal is completed, by controlling the opening and closing of the discharge hopper 6, the treated grain can be conveniently discharged from the cylinder for subsequent storage or processing.

[0034] Since the discharge hopper 6 is located at the bottom of the cylinder, and is usually designed to be inclined or with a vibrating device, it can effectively prevent the incomplete removal of impurities or dust from being discharged with the grain. This design ensures the purity and quality of the discharged grain.

[0035] In one embodiment, a glass window 7 is provided on the cylinder 1.

[0036] The main function of the glass window 7 is to allow the operator to directly observe the internal grain state, stirring condition and dust suction effect without opening the cylinder body 1. This intuitive monitoring method helps the operator to discover and handle possible problems in time, such as uneven grain accumulation, agitator blockage or poor dust suction effect, etc.

[0037] In the present embodiment, the rotating shaft 31 is provided with a plurality of stirring shovels 32 distributed in a ring shape, and the frame body 1 is provided with a driving member 33 connected with the rotating shaft 31 and used for driving the rotating shaft 31 to rotate.

[0038] The rotating shaft 31 is the main supporting structure of the agitator 3, which penetrates through the inside of the cylinder body 2 and is kept relative rotation with the cylinder body 2 through a bearing. At the same time, the rotating shaft 31 is also the key component for the driving member 33 to transmit torque and rotational speed, ensuring that the stirring shovels 32 can rotate in the predetermined speed and direction.

[0039] The rotating shaft 31 can drive the stirring shovels 32 to uniformly turn over the grain inside the cylinder body 2. This turning over not only helps to expose the impurities inside the grain, but also helps to improve the dust removal efficiency of the dust suction mechanism 4. The stirring shovels 32 can effectively turn over and mix the grain, ensuring that each grain can be fully treated and dusted.

[0040] The driving member 33 is the power source of the agitator 3, which provides stable power for the rotation of the rotating shaft 31 and the stirring shovels 32.

[0041] As a preferred embodiment, the stirring shovels 32 include a fixed column 321 provided on the rotating shaft 32, the fixed column 321 is internally provided with an electric heating rod 322, and the fixed column 321 is provided with a turning shovel 323 at the other end.

[0042] The fixed column 321 is the main structural component of the stirring shovels 32, one end of which is connected with the rotating shaft 31, and the other end is connected with the turning shovel 323. The stirring shovels 32 can stably rotate and turn over the grain under the driving of the rotating shaft 31.

[0043] In addition to the basic connection and support function, the fixed column 321 is internally provided with a cavity for installing the electric heating rod 322, so that the electric heating rod 322 can be closely embedded in the fixed column 321, which not only ensures the heating effect, but also avoids the safety hidden danger that the electric heating rod 322 is directly exposed to the external environment.

[0044] The electric heating rod 322 can help to adjust the humidity of the grain by generating heat. In a humid environment, the electric heating rod 322 can accelerate the evaporation of the moisture inside the grain, thereby reducing the humidity of the grain.

[0045] The turnover shovel 323 is the part of the stirring shovel 32 that directly contacts the grain. Its shape and angle are usually designed according to the characteristics of the grain and the processing requirements. Under the drive of the rotating shaft 31, the turnover shovel 323 can effectively turn and mix the grain, ensuring that each grain is fully processed and heated.

[0046] Compared with traditional stirring shovels, the turnover shovel 323 with an electric heating rod can not only turn the grain but also make the internal impurities of the grain more easily removed by the dust removal mechanism 4 through heating. This design not only improves the dust removal efficiency but also enhances the sanitary quality of the grain.

[0047] Specifically, the driving member 33 includes a driving motor 331 arranged on the frame body 1. One end of the rotating shaft 31 extends out of the cylinder body 1, and the output shaft of the driving motor 331 and one end of the rotating shaft 31 are both provided with a belt pulley 332. The two belt pulleys 332 are connected by a belt transmission.

[0048] The driving motor 331 is responsible for converting electrical energy into mechanical energy. It drives the belt pulley 332 to rotate through the belt transmission, providing stable power for the rotation of the stirring shovel 32. By adjusting the speed and direction of the motor, precise control of the working state of the stirring shovel 32 can be achieved.

[0049] The driving motor 331 usually has a speed regulator and a controller, allowing the operator to adjust the speed and direction of the motor as needed. This flexibility ensures that the stirring shovel 32 can adapt to different types and quantities of grain processing requirements, achieving the best dust removal effect.

[0050] The belt transmission also has a certain buffering and damping effect, which can reduce the impact and vibration on the stirring shovel 32 and the cylinder body 1 caused by the start and stop of the motor. This design not only prolongs the service life of the equipment but also improves the stability and reliability of the work.

[0051] In one embodiment, the frame body 1 is also provided with a plurality of fixing frames 8 arranged oppositely. One end of the fixing frame is connected with the conveying pipe 43 and used to support the conveying pipe 43.

[0052] One end of the fixing frame 8 is connected with the conveying pipe 43, and the other end is firmly installed on the frame body 1. The conveying pipe 43 can maintain a stable position and shape during work, avoiding displacement or deformation caused by vibration or external force. At the same time, the fixing frame 8 also plays a role in dispersing the weight of the conveying pipe 43, reducing the burden on the single support point and improving the overall stability of the equipment.
