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 full-ventilation 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 embedded in the silo. A conveyor corridor is located at the bottom of the silo, with a grain unloading port located on the floor along the corridor. 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.

[0005] To ensure convenient grain delivery during transfer and storage, existing shallow silos in my country often utilize trough ventilation systems. Typical duct layouts include radial, circular, comb, flat, and F-shaped ducts. However, these systems still suffer from small air outlets, high ventilation resistance, poor cooling performance, and dead zones. Even with multiple fans operating simultaneously, ventilation efficiency remains unchanged. Summary of the Invention

[0006] The purpose of the utility model is to provide a novel multifunctional circular bulk grain silo bottom assembled full-ventilation grain discharge integrated device to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A novel multifunctional circular bulk grain silo bottom-assembled fully ventilated grain discharge integrated device is designed. The device is conical in shape and comprises a top plate and a bottom plate connected to the top plate. A reinforcement structure and a fully ventilated system are provided between the top plate and the bottom plate.

[0009] The top plate is a frame structure, the smallest unit is a quadrilateral area surrounded by two adjacent radial partitions and circumferential beams, and the top plate is covered with a sieve plate, which is adapted to the smallest unit of the top plate;

[0010] Preferably, the consolidation structure includes radial partitions and circumferential beams arranged between the top plate and the bottom plate. The diameter of the circumferential beams gradually increases from the center of the warehouse to the warehouse wall. The circumferential beams and the radial partitions are cross-welded to each other to form a grid-shaped configuration.

[0011] Preferably, the radial partitions and circumferential beams are made of plastic plates or steel plates, and the radial partitions and circumferential beams 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.

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

[0013] Preferably, the full ventilation system includes radial partitions, circumferential beams, and ventilation holes arranged between the top plate and the bottom plate, and a main air duct is provided on the central tube. During ventilation operation, the wind enters the ventilation holes through the main air duct and is dispersed between every two adjacent radial partitions, and finally enters the warehouse through the top plate to form a full ventilation system.

[0014] Preferably, the radial partition and the circumferential beam 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°.

[0015] Preferably, the radial partition is grooved above and circumferential beams are arranged along its entire length, and corbels are arranged above both sides of the radial partition without grooves, and the top elevation of the corbels is equal to the bottom elevation of the top plate.

[0016] The utility model proposes a new multifunctional circular bulk grain silo bottom assembled full ventilation integrated grain discharge device, which has the following beneficial effects:

[0017] 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;

[0018] 2. The ventilation system is set between the radial partitions to form a full ventilation system, eliminating the original air duct setting and making the mechanical ventilation process faster and more effective;

[0019] 3. The circumferential beams and vertical partitions are fixed by welding, and the radial partitions position the entire device and the bottom plane of the silo;

[0020] 4. The radial partitions and circumferential beams 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;

[0021] 5. 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.

[0022] 6. From the center of the silo to the silo wall, the height of the radial partition gradually increases. The angle between the top plate and the bottom plane of the silo 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.

[0023] 7. Slots are cut above the radial partitions and circumferential beams are arranged along their entire length. Corbels are arranged above both sides of the radial partitions in the non-slotted areas. The top elevation of the corbels is equal to the bottom elevation of the top plate. Through the arrangement of the corbels, the air device used for mechanical ventilation is raised as a whole without changing the air flow path of the original mechanical ventilation corridor, thus ensuring the normal use of mechanical ventilation during the entire grain storage process.

[0024] 8. The top plate of the device is made of cast iron or steel plate. The top plate has a conical surface and is installed on the radial partitions through a fixing device. The conical top plate has a smooth surface and the angle it forms with 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 beams and radial partitions. On the one hand, the top plate, circumferential beams and radial partitions form a whole, making the top plate more rationally stressed. 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.

[0033] See also Figure 1-Figure 5 In the embodiment of the utility model, a novel multifunctional circular bulk grain silo bottom-assembled fully ventilated grain discharging 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 and a fully ventilated system are provided between the top plate 1 and the bottom plate 4;

[0034] The top plate 1 is a frame structure, the smallest unit of which is a quadrilateral area surrounded by two adjacent radial partitions 2 and circumferential beams 3. A sieve plate 12 is laid on the top plate 1, and the sieve plate 12 is adapted to the smallest unit of the top plate 1.

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

[0036] Furthermore, the radial partition 2 is made of plastic or steel plate, the upper part of the radial partition 2 is grooved and a circumferential beam 3 is arranged along its entire length, and corbels 13 are arranged at the non-grooved positions above both sides of the radial partition 2, and the top elevation of the corbels 13 is equal to the bottom elevation of the top plate 1.

[0037] To go further, the circumferential beam 3 is made of a plastic plate or a steel plate. The circumferential beam 3 is arranged throughout the length of the slot above the radial partition 2. The circumferential beam 3 is fixed to the top plate 1 and the radial partition 2 by welding. The height of the circumferential beam 3 depends on the height of the conical top plate 1 of the grain discharge device. At the same time, the diameter of the circumferential beam 3 gradually increases from the center of the warehouse to the warehouse wall. The circumferential beam 3 and the radial partition 2 are cross-welded to each other to form a grid-shaped configuration. In this way, a support with a certain angle is formed, which provides a basis for the construction of the top plate slope; at this point, the top plate 1, the radial partition 2, the circumferential beam 3 and the bottom plate 4 form a whole, which constitutes the force-bearing structure of the entire grain discharge device, and is also the frame of the entire device.

[0038] Secondly, the corbels 13 are made of plastic or steel and welded to a specific location above both sides of the radial baffles 2. The top elevation of the corbels 13 is equal to the height of the top plate 1. The radial baffles 2 primarily bear the pressure from the corbels 13, allowing them to withstand the pressure of grain from the top plate 1, thereby maintaining the structural stability of the entire equipment.

[0039] In addition, the top plate 1 is made of cast iron or steel plate and is installed on the radial partitions 2 via a fixing device 15 . The corbels 13 between the radial partitions 2 provide support for the installation of the top plate 1 .

[0040] The sieve plate 12 is made of stainless steel, and is fully covered and fixed on the top plate 1. The opening rate of the sieve plate 12 is 30%, and the size of the opening is limited to be smaller than the minimum particle size of the stored grain.

[0041] The bottom plate 4, the radial partition plate 2 and the circumferential beam 3 are welded together to form a whole, and a top surface thereof has a certain angle with the bottom of the granary, the angle being θ, and 0°≤θ≤60°.

[0042] 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.

[0043] In summary, the beneficial effects of the present invention are as follows:

[0044] 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;

[0045] 2. The ventilation system is set between the radial partitions to form a full ventilation system, eliminating the original air duct setting and making the mechanical ventilation process faster and more effective;

[0046] 3. The circumferential beams and vertical partitions are fixed by welding, and the radial partitions position the entire device and the bottom plane of the silo;

[0047] 4. The radial partitions and circumferential beams 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] 5. 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] 6. From the center of the silo to the silo wall, the height of the radial partition and the diameter of the circumferential beam gradually increase. The angle between the top plate of the device and the plane of the silo bottom 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] 7. Slots are cut above the radial partitions and circumferential beams are arranged along their entire length. Corbels are arranged above both sides of the radial partitions in the non-slotted areas. The top elevation of the corbels is equal to the bottom elevation of the top plate. Through the arrangement of the corbels, the air device used for mechanical ventilation is raised as a whole without changing the air flow path of the original mechanical ventilation corridor, thus ensuring the normal use of mechanical ventilation during the entire grain storage process.

[0051] 8. The top plate of the device is made of cast iron or steel plate. The top plate has a conical surface and is installed on the radial partitions through a fixing device. The conical top plate has a smooth surface and the angle it forms with 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 beams and radial partitions. On the one hand, the top plate, circumferential beams and radial partitions form a whole, making the top plate more rationally stressed. 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.
