Description

Technical Field

[0001] This utility model relates to the field of grain suction machine technology, and in particular to a dust removal device for a mobile grain suction machine. Background Technology

[0002] With the advancement of agricultural modernization, the scale of grain production and storage is constantly expanding. Especially in large-scale grain storage and transportation, grain cleaning and absorbing have become crucial steps. Effective grain absorption and dust removal are key to improving operational efficiency and protecting the environment and human health. Existing storage silos suffer from problems such as grain accumulation, uneven discharge, and blockages during grain transport and storage, affecting the smoothness and continuity of operations. Furthermore, existing dust removal equipment is often designed as static filtration or simple dust-collecting fan systems, which often fail to effectively improve the contact efficiency between grain and the dust-collecting airflow, resulting in unsatisfactory dust removal effects, difficulty in completely removing dust, ultimately causing environmental pollution and even impacting the health of operators. Utility Model Content

[0003] The purpose of this invention is to integrate a storage silo, a storage silo dust removal system, and a negative pressure Roots blower onto a support frame with self-locking casters and handles. This design saves space and adapts to different operating scenarios. Furthermore, the storage silo employs a nested structure and is equipped with a wave filter plate and other dust removal features, effectively improving dust removal during grain suction. These innovative designs solve the dust removal problem during grain suction, enhancing operational convenience and efficiency while ensuring environmental cleanliness and the health and safety of workers.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A mobile grain suction machine dust removal device includes a support frame, on which a storage silo is mounted. The top of the storage silo is covered by an upper cover. A dust removal system is installed on the side of the storage silo and mounted on a first fixed support plate on the support frame. A negative pressure Roots blower is also connected to the storage silo and mounted on a second fixed support plate on the support frame. The negative pressure Roots blower is connected to the storage silo via a connecting pipe. A grain suction pipe connection port is provided on one side of the upper cover, and a corresponding discharge port is located below the storage silo. The device has a leakage hopper, and the support frame is equipped with handles for easy movement. The bottom of the support frame is equipped with self-locking casters. By integrating the storage hopper, the storage hopper dust removal system, and the negative pressure Roots blower onto the support frame with self-locking casters and handles, the device achieves an integrated mobile design. This saves space and can flexibly adapt to different grain suction operation scenarios (such as different grain piles and different transfer points). At the same time, the grain suction (negative pressure Roots blower) and dust removal (storage hopper dust removal system) functions are integrated, eliminating the need for additional independent dust removal equipment and improving the convenience and efficiency of operation.

[0006] Furthermore, the storage silo includes an outer shell and a conical silo body embedded within the outer shell. A corrugated filter plate and a filter plate are sequentially arranged in the accommodating cavity between the outer shell and the conical silo body along the airflow direction. An electric control valve for controlling the discharge is also installed at the bottom outlet of the conical silo body. The storage silo adopts a nested structure of "outer shell + conical silo body." The sloping design of the conical silo body guides the grain to naturally converge at the outlet, reducing the probability of grain residue and discharge blockage. The corrugated filter plate and filter plate within the accommodating cavity can pre-treat the grain during the suction process, reducing the load on the subsequent dust removal system of the storage silo. The electric control valve can precisely control the discharge rhythm, preventing excessively rapid discharge from causing overflow from the silo or secondary dust generation.

[0007] Furthermore, the wave filter plate is used to disperse and fall the grain, which can spread the grain out, making it easier to clean up the dust. The wave filter plate can disperse and spread the concentrated falling grain, increasing the contact area between the grain and the dust removal airflow, avoiding the accumulation of grain to form "dust removal dead corners", making it easier for the dust carried by the grain to be stripped off by the airflow, and effectively improving the initial dust removal effect in the grain suction process.

[0008] Furthermore, the filter plate is fitted to the inner wall of the outer shell of the silo, and the installation position of the filter plate corresponds to the air inlet of the silo dust removal system. This allows for the filtration of grain and direct adsorption of dust. The silo dust removal system includes a dust removal fan, a pulse jet assembly, and a dust collection box. The air inlet of the dust removal fan is connected to the silo chamber outside the filter plate. The nozzle of the pulse jet assembly faces the inner surface of the filter plate. The dust collection box is detachably connected to the bottom outlet of the silo dust removal system. The arrangement of the filter plate fitting to the inner wall of the silo and corresponding to the air inlet of the silo dust removal system allows for direct filtration and adsorption of passing grain, reducing dust diffusion into the silo. Furthermore, dust intercepted by the filter plate is directly absorbed by the silo dust removal system, reducing dust residue in the silo. The fitted installation also saves valuable space inside the silo.

[0009] Furthermore, the corrugated filter plate has a continuous folded edge structure. The corrugated filter plate is inclinedly arranged in the receiving cavity, and the extension direction of the folded edge of the corrugated filter plate intersects with the grain falling direction. The continuous folded edge structure and the inclined arrangement of the corrugated filter plate with the folded edge extension direction intersecting with the grain falling direction can not only extend the falling path of the grain and further disperse the accumulated grain, enhance the dispersion effect of the grain, and improve the dust separation efficiency, but also prevent the grain from clogging in the filter plate area through the guiding effect of the folded edge, ensuring the smoothness of the grain suction operation.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The corrugated filter plate, with its unique continuous folded edges and inclined structure, disperses and spreads the concentrated flow of grain. This not only increases the contact area between the grain and the air, making it easier for adhering dust to be carried away by the airflow, completing the initial "pre-dust removal," but also avoids "dust-removing dead zones" formed by grain accumulation, laying a good foundation for subsequent deep dust removal. The filter plate, fitted to the outer shell, is located directly at the air inlet of the dust removal system, efficiently filtering and adsorbing fine dust that has passed through the corrugated filter plate. Combined with pulse jet cleaning and dust collection box collection, a closed and efficient dust removal loop is formed. This synergistic mechanism reduces the load on the main dust removal system, ensuring that the dust concentration in the silo is continuously and effectively controlled throughout the grain suction process, improving the final cleanliness of the grain.

[0012] 2. The storage silo of the device adopts a unique nested structure of "outer shell + conical silo". The conical silo utilizes the principle of gravity to naturally guide the grain towards the central discharge port, effectively avoiding grain residue or accumulation on the silo walls and reducing the risk of discharge blockage. In addition, the application of electric control valves provides a precise and controllable means of discharge, allowing operators to accurately adjust the discharge speed and flow rate according to the needs of subsequent transfer or packaging.

[0013] 3. The nested structure of "outer shell + conical silo" utilizes the principle of gravity to naturally guide the grain to the discharge port efficiently, minimizing grain residue on the silo walls, ensuring complete emptying of materials, and avoiding cleaning difficulties and cross-contamination.

Detailed Implementation

[0017] 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.

[0018] Combination Figure 1-2 As shown, a mobile grain suction machine dust removal device includes a support frame 1, a storage silo 2 mounted on the support frame 1, an upper cover 3 covering the top of the storage silo 2, a storage silo dust removal system 5 mounted on the side of the storage silo 2, the storage silo dust removal system 5 being installed on a first fixed support plate 4 on the support frame 1, a negative pressure Roots blower 7 connected to the storage silo 2, the negative pressure Roots blower 7 being installed on a second fixed support plate 6 on the support frame 1, the negative pressure Roots blower 7 being connected to the storage silo 2 via a connecting pipe 8, a grain suction pipe connection port 9 being provided on one side of the upper cover 3, and a leakage outlet being provided below the storage silo 2 corresponding to its discharge port. The silo 10 and the support frame 1 are also equipped with handles 11 to facilitate the movement and operation of the device. The bottom of the support frame 1 is equipped with self-locking casters 12. By integrating the storage silo, the storage silo dust removal system, and the negative pressure Roots blower onto the support frame with self-locking casters and handles, the device achieves an integrated mobile design. This not only saves space but also flexibly adapts to different grain suction operation scenarios (such as different grain piles and different transfer points). At the same time, the grain suction (negative pressure Roots blower) and dust removal (storage silo dust removal system) functions are integrated, eliminating the need for additional independent dust removal equipment and improving the convenience and efficiency of operation.

[0019] The storage silo 2 includes a silo shell 21 and a conical silo body 101 embedded within the silo shell 21. A corrugated filter plate 22 and a filter plate 23 are sequentially arranged in the accommodating cavity between the silo shell 21 and the conical silo body 101 along the airflow direction. An electric control valve 102 for controlling the discharge is also installed at the bottom outlet of the conical silo body 101. The storage silo adopts a nested structure of "silo shell + conical silo body." The sloping design of the conical silo body guides the grain to naturally converge at the outlet, reducing the probability of grain residue and discharge blockage. The corrugated filter plate and filter plate within the accommodating cavity can pre-treat the grain during the grain suction process. This reduces the load on the subsequent dust removal system of the storage silo; the electric control valve can precisely control the discharge rhythm, avoiding excessively fast discharge that could lead to overflow from the silo or secondary dust generation; the corrugated filter plate 22 is used to disperse the falling grain, spreading it out for easier dust removal. The corrugated filter plate can disperse the concentrated falling grain, increasing the contact area between the grain and the dust removal airflow, preventing grain accumulation and the formation of "dust removal dead corners," making it easier for the dust carried by the grain to be stripped off by the airflow, effectively improving the initial dust removal effect during the grain suction process; the filter plate 23 is set against the inner wall of the outer shell 21 of the silo, and the installation position of the filter plate 23 corresponds to... The inlet of the storage silo dust removal system 5 filters the grain and directly adsorbs dust. The system includes a dust removal fan, a pulse jet assembly, and a dust collection box. The inlet of the dust removal fan connects to the outer chamber of the silo body, and the nozzles of the pulse jet assembly face the inner surface of the filter plate. The dust collection box is detachably connected to the bottom outlet of the storage silo dust removal system. The filter plate fits against the inner wall of the silo body and is arranged in accordance with the inlet of the dust removal system. This arrangement allows for direct filtration and adsorption of passing grain, reducing dust diffusion into the storage silo. Furthermore, it ensures that dust intercepted by the filter plate is directly removed by the storage silo dust removal system. The system removes dust, reducing the amount of dust residue in the silo. The close-fitting installation also saves valuable space inside the silo. The corrugated filter plate 22 has a continuous folded edge structure and is arranged at an angle within the receiving cavity. The folded edge extension direction of the corrugated filter plate 22 intersects with the grain falling direction. This continuous folded edge structure, the angled arrangement, and the fact that the folded edge extension direction intersects with the grain falling direction not only extend the grain's falling path and further disperse the accumulated grain, enhancing the grain dispersion effect and improving dust separation efficiency, but also prevents grain from clogging the filter plate area through the guiding effect of the folded edges, ensuring smooth grain suction operations.

[0020] Working principle: The operator moves the equipment to the target position and locks it using handle 11 and self-locking casters 12. The suction pipe is connected to the suction pipe connection port 9 of the upper cover 3. The negative pressure Roots blower 7 is started, and a stable negative pressure airflow is delivered to the storage silo 2 through the connecting pipe 8. The mixture of grain and dust is continuously sucked into the conical silo 101. The inclined surface of the conical silo guides the mixture to rotate and fall. Large dust particles are initially separated using gravity and centrifugal force. The falling mixture first passes through the corrugated filter plate 22 in the receiving chamber. Its continuous folded edge structure disperses the grain, extending the falling path and filling the air. The system removes fine dust from the surface while preventing grain blockage. The removed dust flows with the airflow through the filter plate 23, which is attached to the outer shell of the silo 21, and is precisely adsorbed and intercepted, preventing dust spread or wear on the power components. The dust removal system 5 of the storage silo is activated, and the dust removal fan sucks in the dust from the outside of the filter plate. The pulse jet cleaning component cleans the dust accumulated on the filter plate periodically. The dust is finally collected in a detachable dust collection box for easy cleaning later. The clean grain after dust removal gathers in the conical silo 101 and goes to the bottom discharge port. The discharge speed and discharge volume are precisely adjusted by the electric control valve 102. The grain is then directionally conveyed to the receiving equipment through the leakage bin 10. The negative pressure Roots blower provides power throughout the process. The multi-stage filtration and dust removal system forms an efficient purification link. The mobile design can be quickly adapted to different operating scenarios, forming a complete closed-loop operation of "mobile positioning - grain suction and dust removal - precise discharge".
