Description

Technical Field

[0001] The utility model relates to the technical field of design of ventilation bottom plates in granaries, in particular to a novel fully ventilated bottom plate tooling in granaries. Background Art

[0002] In today's era of rapid technological advancement and booming industry, silos have become a crucial component of modern logistics and storage systems. Whether used for grain storage or for other bulk cargo storage, silos play an indispensable role. In China, the primary ventilation method for flat-bottomed grain silos is floor trough ventilation. This floor trough ventilation system features a unique structure and operating principle. The floor trough serves as the primary ventilation channel, and a specially designed floor trough cover is installed above it. These floor trough covers are not simply shielding components; they feature a carefully designed perforated structure. When a centrifugal fan outside the silo starts operating, it generates a powerful airflow that continuously enters the floor trough. The airflow penetrates the grain pile through the perforations in the floor trough cover, evenly and orderly penetrating it. These air-carrying airflows gradually spread throughout the grain pile like invisible tentacles, thoroughly interfering with every part of the grain. This method effectively regulates the temperature and humidity within the grain pile, achieving the important goals of cooling and dehumidifying the grain within the silo, creating an optimal environment for long-term, safe storage.

[0003] However, the existing ventilation design in granaries uses trough ventilation, which is fixed and convenient. However, in some structures (such as shallow circular silos), there may be ventilation dead corners, resulting in insufficient overall ventilation uniformity. This will affect the storage effect and quality of items in the warehouse, such as the temperature and humidity control of grain. Due to the structural and layout limitations of the trough ventilation system, the air flow resistance during the ventilation process will increase, thereby increasing the energy consumption of the ventilation equipment. This will undoubtedly increase the operating costs for warehouses that require long-term ventilation operations. At the same time, the trough ventilation ducts are usually located under the floor. If they are not cleaned and maintained regularly, the ventilation ducts will be blocked or damaged, which will affect the ventilation effect. The total air volume of the trough ventilation is limited by the trough cross-section and wind speed, and the ventilation time is relatively long. Especially in the tropical and subtropical regions of southern my country, due to the high temperature and high humidity all year round, there are few suitable ventilation opportunities, so the temperature of the grain in the warehouse needs to be lowered in a relatively short time. Therefore, in response to the above shortcomings, a new type of fully ventilated bottom plate tooling in the granary is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a new fully ventilated bottom plate tooling in the granary, aiming to improve the problems of low ventilation and cooling rate and local dead corners in some flat-bottom silos in the existing technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A novel fully ventilated bottom plate tooling in a granary, comprising a silo wall and a plurality of rivets, wherein a discharging assembly for discharging grain is provided inside the silo wall, a plurality of steel legs are fixedly connected to the inner top side of the silo wall, the tops of the plurality of steel legs are fixedly connected to a supporting steel frame, the tops of the supporting steel frames are fixedly connected to a plurality of limiting angle steels, a plurality of ventilation cover plates are provided on the top of the supporting steel frames, a plurality of circumferential support plates are fixedly connected to the outside of the supporting steel frames, the tops of the plurality of circumferential support plates are fixedly connected to edge guard plates, the insides of the plurality of edge guard plates are fixedly connected to two fixing rivets, the outsides of the plurality of edge guard plates are fixedly connected to assembled silo wall panels, the insides of the plurality of edge guard plates are fixedly connected to two silo wall fixing bolts, and the outsides of the plurality of ventilation cover plates are fixedly connected to connecting plates through the rivets;

[0009] As a further description of the above technical solution:

[0010] The material of the ventilation cover is galvanized sheet material. The end folding design of the ventilation cover not only improves the pressure-bearing strength of the single cover, but also solves the hidden danger of materials entering under the ventilation plate along the embedded angle steel;

[0011] As a further description of the above technical solution:

[0012] The installation of the ventilation cover is to first install the lower frame according to the design, and then put the inner folding side of the upper cover into the outer folding groove of the upper cover from bottom to top until it reaches the top of the warehouse wall;

[0013] As a further description of the above technical solution:

[0014] The two parallel ventilation cover plates are covered with a connecting plate, and the connecting plate and the ventilation cover plates on both sides are fixed together by rivets, so that not only the gap between the two single cover plates is eliminated, but also the lateral movement between the single ventilation cover plates is prevented;

[0015] As a further description of the above technical solution:

[0016] The bottom plate of the edge guard is designed in an arc shape and punched in an open bridge style, and is fixed to the ventilation cover plate with the rivets. The vertical surface of the edge guard is punched after being formed according to the corrugation of the warehouse wall, and is fixed to the warehouse wall with the warehouse wall fixing bolts.

[0017] The utility model has the following beneficial effects:

[0018] In the utility model, the problems of low ventilation and cooling rate and local dead corners in flat-bottomed silos are solved through the effective installation of ventilation covers and structures such as edge guards. The utility model is suitable for large areas in tropical and subtropical regions where there are relatively few suitable ventilation opportunities.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figures 1 to 3 , the utility model provides an embodiment: a new fully ventilated bottom plate tooling in a granary, comprising a silo wall 1 and a plurality of rivets 16, the silo wall 1 provides a storage space and a support base for the internal fully ventilated bottom plate design. The interior of the silo wall 1 is provided with a discharging assembly for discharging grain, the discharging assembly comprises a silo cleaning machine mounting plate 2, the exterior of the silo cleaning machine mounting plate 2 is fixedly connected to the interior of the silo wall 1, the interior of the silo cleaning machine mounting plate 2 is fixedly connected with a plurality of fixed anchor bolts 3, the interior of the silo cleaning machine mounting plate 2 is provided with a silo cleaning machine body 4, the silo cleaning machine mounting plate 2 provides a stable platform foundation for the installation of the silo cleaning machine. The function of the silo cleaning machine body 4 is to push the grain in the silo to the central discharge port 9 through its own mechanical structure and working principle when grain needs to be discharged, thereby realizing the smooth output of grain. A central discharge port 9 is provided inside the silo wall 1;

[0030] Reference Figures 2 to 4, a plurality of steel legs 5 are fixedly connected to the inner top side of the warehouse wall 1, and a support steel frame 6 is fixedly connected to the top of the plurality of steel legs 5. The steel legs 5 provide stable support for the support steel frame 6 above. A plurality of limiting angle steels 7 are fixedly connected to the top of the support steel frame 6, and a plurality of ventilation cover plates 8 are arranged on the top of the support steel frame 6. The limiting angle steels 7 play a role in limiting and positioning the installation position of the ventilation cover plates 8, ensuring that the ventilation cover plates 8 can be kept in the correct position during installation and use. The installation of the ventilation cover plates 8 is to first install the lower frame according to the design, and then put the inner folding side of the upper cover plate into the outer folding groove of the upper cover plate from bottom to top until it reaches the top of the warehouse wall 1, so that the ventilation cover plates 8 are tightly connected to each other to form a continuous ventilation bottom surface. The material of the ventilation cover plate 8 is galvanized sheet, which is not only thin, light in weight and high in strength, but also uses less material than traditional grain storage trough covers, saving costs. The end folding design of the ventilation cover plate 8 not only improves the pressure-bearing strength of the single cover plate, but also solves the hidden danger of materials entering under the ventilation plate along the embedded angle steel. The outside of the supporting steel frame 6 is fixedly connected with multiple circumferential support plates 10;

[0031] Reference Figures 5 to 7 The tops of multiple circumferential support plates 10 are fixedly connected to edge guard plates 11. The main function of the circumferential support plates 10 is to provide support for the edge guard plates 11 above. The bottom plate of the edge guard plate 11 is designed in an arc shape, with bridge-type punching holes, and is fixed to the ventilation cover plate 8 with rivets 16. The vertical surface of the edge guard plate 11 is punched according to the corrugation of the silo wall 1 and is fixed to the silo wall 1 with silo wall fixing bolts 14. The interior of multiple edge guard plates 11 is fixedly connected with two fixing rivets 12, which solves the gap problem between the rectangular ventilation cover plate 8 and the inner wall of the circular silo and prevents materials from leaking under the ventilation plate. The outsides of multiple edge guards 11 are fixedly connected to the assembled silo wall panels 13, and the insides of multiple edge guards 11 are fixedly connected to two silo wall fixing bolts 14. The outsides of multiple ventilation cover plates 8 are fixedly connected to connecting plates 15 by rivets 16. A connecting plate 15 is covered on two parallel ventilation cover plates 8, and the connecting plate 15 and the ventilation cover plates 8 on both sides are fixed to form a whole by rivets 16. In this way, not only the gap between the two single cover plates is eliminated, but also the lateral movement between the single ventilation cover plates 8 is prevented, which eliminates the gap between the single cover plates and prevents the lateral movement between the single ventilation cover plates 8. It plays a vital role in maintaining the overall structural stability and sealing of the ventilation bottom plate, and ensures the normal function of the ventilation bottom plate during the use of the granary.

[0032] Working principle: There are multiple steel legs 5 on the top side of the silo wall 1, and the top of the legs is connected to the supporting steel frame 6. The top of the supporting steel frame 6 has multiple limit angle steels 7 and ventilation cover plates 8. When installing the ventilation cover plates 8, first install the lower frame. The inner folding edge of the upper cover plate is placed from bottom to top into the outer folding edge groove of the upper cover plate until it reaches the top of the silo wall 1. It is made of galvanized sheet metal. The end folding edge design can improve the pressure bearing strength and prevent materials from entering the bottom along the embedded angle steel. There are multiple circumferential support plates 10 on the outside of the supporting steel frame 6. The bottom plate of the edge guard plate 11 on the top is arc-shaped and has bridge-type punching. It is fixed to the ventilation cover plate 8 with rivets 16. The facade is punched according to the corrugation of the silo wall 1 and is fixed to the silo wall 1 with silo wall fixing bolts 14. There are fixing rivets 12 inside the edge guard plate 11, and the outside is connected to the assembled silo wall plate 13. The outside of the ventilation cover 8 is connected to the connecting plate 15 by rivets 16. A connecting plate 15 is covered on the two parallel ventilation covers 8 and fixed with rivets 16, which can eliminate the gap between the individual cover plates and prevent lateral movement. During installation, first install the upper cover from a specific position, and then install the lower cover from another position until it reaches the opposite silo wall 1. During the installation process, attention should be paid to the end treatment of the ventilation cover 8 to prevent materials from entering and accumulating below. In addition, the problem of lateral displacement of the ventilation cover 8 is solved by adding a connecting plate 15 to the parallel ventilation cover 8, and the edge guard 11 is set along the inner wall of the silo to solve the gap problem between the rectangular ventilation cover 8 and the inner wall of the circular silo, preventing materials from leaking under the ventilation plate, and finally completing the installation of the ventilation bottom plate.
