Description

Technical Field

[0001] The utility model relates to the technical field of granary ventilation and grain discharging, in particular to a novel multifunctional circular bulk granary bottom assembled ventilation and grain discharging integrated device. Background Art

[0002] Shallow silos offer advantages such as low cost per unit volume, reasonable structural stress, high degree of mechanization, large storage capacity per unit, small footprint, good airtightness, and strong earthquake resistance. Consequently, they have been widely promoted in China and have played a vital role in achieving mechanized grain storage.

[0003] Existing shallow silos typically have a single inlet at the center of the silo's roof, where grain is fed into the silo via a scraper conveyor. A conveyor corridor is located at the bottom of the silo, with a grain unloading port located along the corridor's surface. During unloading, the port is opened, allowing the grain to flow out of the silo by itself. The conveyor in the corridor then completes the unloading process. However, since the silo floor has no or a very small inclination, the remaining grain must be cleared out using a grain scraper or auger. This makes unloading the grain somewhat more difficult.

[0004] In order to improve grain discharge efficiency and reduce grain discharge costs without reducing the mechanization level of shallow silos, most shallow silos currently use grain scrapers or silo-cleaning augers to clean the remaining grain at the bottom of the silo after discharge. However, the above-mentioned method of cleaning the remaining grain at the bottom of the silo still has some problems that need to be solved, which limits the grain discharge efficiency of shallow silos to a certain extent. Summary of the Invention

[0005] The purpose of the utility model is to provide a novel multifunctional circular bulk grain silo bottom assembled ventilation and grain discharge integrated device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A novel multifunctional circular bulk grain silo bottom assembly-type integrated ventilation and grain discharge device is designed, which is conical and includes a top plate and a bottom plate connected to the top plate, and a reinforcement structure is provided between the top plate and the bottom plate;

[0008] Wherein, the top plate and the bottom plate are both provided with rectangular holes above the ventilation gallery air converging duct and the ventilation gallery branch air duct at the bottom of the warehouse, and the rectangular holes are adapted to the ventilation gallery air converging duct and the ventilation gallery branch air duct at the bottom of the warehouse.

[0009] Preferably, the consolidation structure includes radial partitions and circumferential partitions arranged between the top plate and the bottom plate. The diameter and height of the circumferential partitions gradually increase from the center of the warehouse to the warehouse wall. The circumferential partitions and the radial partitions are cross-welded to each other to form a grid-shaped configuration.

[0010] Preferably, the radial partitions and circumferential partitions are made of plastic plates or steel plates, and the radial partitions and the circumferential partitions are connected by welding to form a grid-shaped force-bearing structure. The force-bearing structure has a certain angle, providing a basis for the construction of the top plate slope.

[0011] Preferably, the height of the circumferential partition gradually increases from the center of the bin to the bin wall, and the height of the circumferential partition depends on the height of the inclined top plate of the grain distributor.

[0012] Preferably, the bottom plate, radial partitions and circumferential partitions are welded together. The bottom plate is elevated relative to the bottom surfaces of the vertical partitions and circumferential partitions to prevent the bottom plate from warping due to uneven support surfaces when the bottom plate is placed.

[0013] Preferably, the radial partition and the circumferential partition are welded to form a whole, and a top surface thereof has a certain angle with the bottom of the granary, the angle is θ, and 0°≤θ≤60°.

[0014] Preferably, grooves are opened above the radial partitions on both sides of the ventilation corridor air duct and beams are arranged along the entire length. Raised parts are provided on both sides of the beams and are made of plastic or steel plates. The elevation of the raised parts is equal to the elevation of the top plate at the corresponding position.

[0015] The utility model proposes a novel multifunctional circular bulk grain silo bottom assembled ventilation and grain discharge integrated device, which has the following beneficial effects:

[0016] 1. The top plate has a smooth surface, which creates little friction with the grain particles, allowing the grain particles to slide down under their own gravity and be discharged through the grain outlet;

[0017] 2. The circumferential partitions are fixed to the top plate and vertical partitions by welding. The circumferential partitions position the entire device and the bottom plane of the silo;

[0018] 3. The radial partitions and circumferential partitions are welded to each other to form a cross-grid structure, which makes the interior of the entire device in the form of a space, saving materials, speeding up the overall construction speed, and further shortening the construction period;

[0019] 4. The partitions and top plates of the device can be produced in a standardized manner in the factory. The processing and manufacturing quality can be effectively controlled and energy-saving and environmentally friendly. The prefabricated products are assembled on site, which greatly reduces the intensity of on-site construction. At the same time, the degree of mechanization is increased, which reduces the number of on-site personnel and saves labor costs. Cross-installation and construction can be carried out, shortening the construction period.

[0020] 5. From the center of the silo to the silo wall, the height of the radial partitions and the circumferential partitions gradually increases. The angle between the top plate and the silo bottom plane is θ, 0°≤θ≤60°. Different angles are used for storing different types of grain, which is convenient for use in silos storing various types of grain.

[0021] 6. Install brackets on both sides of the ventilation corridor and align them vertically with the edges of the ventilation corridor. The arrangement of the brackets raises the air device used for mechanical ventilation as a whole without changing the original air flow path of the mechanical ventilation corridor, thus ensuring the normal use of mechanical ventilation during the entire grain storage process.

[0022] 7. The top plate of the device is made of plastic or steel. The top plate has a conical surface. The intersection of the inner surface of the top plate and the circumferential partition is welded. The surface of the conical top plate is smooth, and the angle between it and the plane of the silo bottom meets the requirements for the self-flow of grain. The lower part of the conical top plate is supported by a mesh structure consisting of circumferential plastic plates and radial partitions. On the one hand, the top plate, circumferential partitions and radial partitions form a whole, making the stress on the plastic top plate more reasonable. In addition, the various components of the device are prefabricated blocks, which improves the assembly rate of the structure, reduces the work on the silo bottom, and makes construction simpler and faster.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0032] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiment.

[0033] See also Figure 1-Figure 7 In the embodiment of the utility model, a novel multifunctional circular bulk grain silo bottom assembly type ventilation grain discharge integrated device is conically arranged, comprising a top plate 1 and a bottom plate 4 connected to the top plate 1, and a consolidation structure is provided between the top plate 1 and the bottom plate 4;

[0034] Among them, the top plate 1 and the bottom plate 4 are both provided with rectangular holes above the ventilation corridor converging duct 10 and the ventilation corridor branch duct 11 at the bottom of the warehouse, and the rectangular holes are adapted to the ventilation corridor converging duct 10 and the ventilation corridor branch duct 11 at the bottom of the warehouse, and the warehouse bottom is also adapted with a discharge auxiliary structure.

[0035] The consolidation structure includes a radial partition 2 and a circumferential partition 3 arranged between the top plate 1 and the bottom plate 4. The diameter and height of the circumferential partition 3 gradually increase from the center of the warehouse to the warehouse wall. The circumferential partition 3 and the radial partition 2 are cross-welded to each other to form a grid-shaped configuration.

[0036] Specifically, the circumferential baffles 3 are made of plastic or steel plates and are secured to the top plate 1 and radial baffles 2 by welding. The height of the circumferential baffles 3 is determined by the height of the conical top plate 1 of the grain discharging device. Furthermore, the diameter and height of the circumferential baffles 3 gradually increase from the center of the silo to the silo wall. The circumferential baffles 3 and the radial baffles 2 are cross-welded to form a grid-like configuration. This creates an angled support, providing a foundation for constructing the top plate's slope.

[0037] Secondly, the bottom plate 4 is elevated relative to the bottom surface of the circumferential partition 3. The purpose of this elevation is to prevent the bottom plate 4 from warping due to unevenness of the supporting surface when the bottom plate 4 is placed. Thus, the top plate 1, the radial partitions 2, the circumferential partitions 3, and the bottom plate 4 form a whole, forming the load-bearing structure of the entire grain discharging device and also the framework of the entire device.

[0038] In addition, the radial baffles 15 on both sides of the ventilation corridor branch duct 11 are made of plastic or steel plates and are arranged along both sides of the ventilation corridor branch duct 11. The height of the radial baffles 15 on both sides of the ventilation corridor branch duct 11 is determined by lofting, and their thickness is greater than the radial baffles 2. The specific thickness is calculated based on the size of the ventilation corridor branch duct 11, and at the same time, the distance between the corresponding corbels 13 between the radial baffles 15 on both sides of the two ventilation corridor branch ducts 11 is equal to the designed width of the ventilation corridor branch duct 11. Among them, the corbels 13 are made of plastic or steel plates and are welded to a certain position above the radial baffles 2 on both sides of the ventilation corridor branch duct 11. The top elevation of the corbels 13 is lower than a certain height of the top plate 1 and is equal to the bottom elevation of the snap plate 12. It mainly bears the pressure from the corbels 13, so that the corbels 13 can withstand the pressure of the grain from the ventilation trough air device. This maintains the structural stability of the entire equipment.

[0039] The top plate 1, the bottom plate 4, the radial partition 2 and the circumferential partition 3 are welded together to form a whole, and a certain angle exists between the top surface and the bottom of the granary, the angle is θ, and 0°≤θ≤60°.

[0040] The ventilation corridor air duct 10 is grooved above the radial partitions 2 on both sides and a beam 14 is arranged along the entire length. Both sides of the beam 14 are provided with a raised portion along the entire length. The raised portion is made of plastic or steel plate. The elevation of the raised portion is equal to the elevation of the corresponding top plate 1.

[0041] The raised portion of the beam 14 is mainly used to prevent the air device from sliding down along both sides of the ventilation corridor air conduit 10 .

[0042] The radial partitions 15 on both sides of the ventilation corridor branch duct 11 are made of plastic or steel plate. They are arranged along both sides of the ventilation corridor branch duct 11. The height of the radial partitions 15 on both sides of the ventilation corridor branch duct 11 is determined by lofting. The thickness is greater than the radial partition 2. The specific thickness is calculated based on the size of the ventilation corridor branch duct 11. At the same time, the distance between the corresponding corbels 13 between the radial partitions 15 on both sides of the two ventilation corridor branch ducts 11 is equal to the designed width of the ventilation corridor branch duct 11. Among them, the corbels 13 are made of plastic or steel plate and are welded to a certain position above the radial partitions 2 on both sides of the ventilation corridor branch duct 11. The top elevation of the corbel 13 is lower than a certain height of the top plate 1 and is equal to the bottom elevation of the snap plate 12. It mainly bears the pressure from the corbel 13, so that the corbel 13 can withstand the pressure of the grain from the ventilation trough air device. This maintains the structural stability of the entire equipment.

[0043] In actual implementation, the silo bottom is provided with a concrete surface 5, and a central tube 6 is formed in the silo, the silo wall is a concrete silo wall 7, the auxiliary discharge structure is adapted to the grain outlet 8, and the silo bottom is a reinforced concrete silo bottom 9.

[0044] In summary, the beneficial effects of the present invention are as follows:

[0045] 1. The surface of the top plate 1 is smooth, and the friction between the top plate and the grain particles is small, so that the grain particles can slide down by their own gravity and be discharged through the grain outlet;

[0046] 2. The circumferential partition 3 is fixed to the top plate 1 and the vertical partition by welding. The circumferential partition positions the entire device and the bottom plane of the silo;

[0047] 3. The radial partitions 2 and the circumferential partitions 3 are welded to each other to form a cross-grid structure, which makes the interior of the entire device in the form of a space, saving materials, speeding up the overall construction speed, and further shortening the construction period;

[0048] 4. The partitions and top plates of the device can be produced in a standardized manner in the factory. The processing and manufacturing quality can be effectively controlled and energy-saving and environmentally friendly. The prefabricated products are assembled on site, which greatly reduces the intensity of on-site construction. At the same time, the degree of mechanization is increased, which reduces the number of on-site personnel and saves labor costs. Cross-installation and construction can be carried out, shortening the construction period.

[0049] 5. From the center of the silo to the silo wall, the height of the radial partitions and the circumferential partitions gradually increases. The angle between the top plate and the silo bottom plane is θ, 0°≤θ≤60°. Different angles are used for storing different types of grain, which is convenient for use in silos storing various types of grain.

[0050] 6. Install brackets on both sides of the ventilation corridor and align them vertically with the edges of the ventilation corridor. The arrangement of the brackets raises the air device used for mechanical ventilation as a whole without changing the original air flow path of the mechanical ventilation corridor, thus ensuring the normal use of mechanical ventilation during the entire grain storage process.

[0051] 7. The top plate of the device is made of plastic or steel. The top plate has a conical surface. The intersection of the inner surface of the top plate and the circumferential partition is welded. The surface of the conical top plate is smooth, and the angle between it and the plane of the silo bottom meets the requirements for the self-flow of grain. The lower part of the conical top plate is supported by a mesh structure consisting of circumferential plastic plates and radial partitions. On the one hand, the top plate, circumferential partitions and radial partitions form a whole, making the stress on the plastic top plate more reasonable. In addition, the various components of the device are prefabricated blocks, which improves the assembly rate of the structure, reduces the work on the silo bottom, and makes construction simpler and faster.
