Description

Technical Field

[0001] The utility model relates to the technical fields of grain bin ventilation and grain discharging, in particular to an integrated device for full ventilation and multi-point grain discharging at the bottom of an assembled multi-functional circular bulk grain bin. Background Technique

[0002] The shallow silo has the advantages of low cost per unit volume, reasonable structural stress, high degree of mechanization, large single bin capacity, small floor area, good airtightness, strong seismic performance, etc. Therefore, the shallow silo has been vigorously promoted in China and plays a crucial role in realizing the mechanized storage of grain.

[0003] In the existing shallow silo, there is generally a grain inlet at the center of the silo top, and the grain is fed into the silo through a scraper conveyor buried in the silo top. A conveying corridor is arranged at the bottom of the silo, and grain discharging ports are opened on the floor of the bottom of the silo along the direction of the corridor. When discharging grain, the grain discharging port is opened, and the grain flows out of the silo by itself, and then the conveyor in the corridor completes the grain discharging operation of the silo. However, due to the fact that the bottom plane of the silo has no inclination or a small inclination, the cleaning operation of the remaining grain in the silo needs to be completed by a grain raking machine or a cleaning auger. This increases the difficulty of grain discharging to a certain extent.

[0004] In order to improve the grain discharging efficiency and reduce the grain discharging cost without reducing the mechanization degree of the shallow silo, at present, most shallow silos use a grain raking machine or a cleaning auger to clean the remaining grain at the bottom of the silo after grain discharging. However, the above methods for cleaning the remaining grain at the bottom of the silo still have some problems to be solved urgently, which limits the grain discharging efficiency of the shallow silo to a certain extent.

[0005] In order to take into account the convenience of grain discharging during the transfer and storage processes, the existing shallow silos in China mostly adopt a underfloor ventilation system. Generally, the air ducts are arranged in forms such as radial, annular, comb-shaped, abundant-shaped, F-shaped air ducts, etc. However, during the use process, there are still problems such as a relatively small air outlet area, a large ventilation resistance, a poor cooling effect and the existence of ventilation dead corners. Under the condition of multiple fans working together, the ventilation effect is not significantly improved. Summary of the Invention

[0006] The purpose of the utility model is to provide an integrated device for full ventilation and grain discharging at the bottom of an assembled multi-functional circular bulk grain bin to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] Design an integrated device for full ventilation and grain discharging at the bottom of an assembled multi-functional circular bulk grain bin, which is symmetrically semi-elliptical in shape, including a top plate and a bottom plate connected to the top plate, and a consolidation structure and a full ventilation system are arranged between the top plate and the bottom plate;

[0009] Among them, the top plate is of a frame structure, and the smallest unit is a quadrilateral area enclosed by two adjacent radial partitions and vertical beams. A sieve plate is laid on the top plate, and the sieve plate is adapted to the smallest unit of the top plate.

[0010] Preferably, the reinforcement structure includes radial partitions and vertical beams arranged between the top plate and the bottom plate. The height of the radial partitions gradually increases from the center of the bin to the bin wall. The vertical beams and the radial partitions are cross-welded to form a grid-shaped configuration.

[0011] Preferably, the radial partitions and vertical beams are made of plastic plates or steel plates. The radial partitions and vertical beams are connected by welding to form a grid-shaped stress structure with a certain angle, providing a basis for the construction of the inclined surface of the top plate.

[0012] Preferably, the bottom plate, radial partitions, and vertical beams are welded. The bottom plate is raised relative to the bottom surface of the radial partitions. The purpose of raising is to prevent the warping of the bottom plate caused by the unevenness of the support surface when the bottom plate is placed.

[0013] Preferably, the full ventilation system includes radial partitions, vertical beams, and ventilation holes arranged between the top plate and the bottom plate. Main air ducts are provided on the concrete bin wall. During ventilation operation, air enters the ventilation holes through the main air ducts and is dispersed between every two adjacent radial partitions, and finally enters the bin through the top plate to form a full ventilation system.

[0014] Preferably, as a further solution of the present invention: the radial partitions, vertical beams, and circumferential partitions are integrally formed by welding, and there is a certain angle between their top surfaces and the bottom of the grain bin, and the angle size is θ, and 0° ≤ θ ≤ 60°.

[0015] Preferably, vertical beams are arranged in a through-long manner by grooving at the upper position of the radial partitions. Bracket feet are arranged at the non-grooved positions above both sides of the radial partitions, and the top elevation of the bracket feet is equal to the bottom elevation of the top plate.

[0016] The present invention provides a multi-functional circular bulk grain bin bottom prefabricated full ventilation grain discharging integrated device, and the beneficial effects are as follows:

[0017] 1. The surface of the top plate is smooth, and the friction generated with the grain particles is small, so that the grain particles can slide down by their own gravity and complete grain discharging through the grain discharging port.

[0018] 2. The ventilation system is arranged 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 vertical beams and vertical partitions are fixed by welding, and the radial partitions position the whole device and the bottom plane of the bin.

[0020] 4. The radial partitions and vertical beams are welded to each other to form a cross-grid structure, making the interior of the entire device in a space form, saving materials, accelerating the overall construction speed, and further shortening the construction period.

[0021] 5. The device partitions and roof can be standardized and produced in the factory. The processing and manufacturing quality can be effectively controlled, energy-saving and environmental-friendly. The prefabricated products are assembled on-site, greatly reducing the on-site construction intensity. At the same time, the mechanization degree is increased, the on-site personnel allocation is reduced, the labor cost is saved, and the cross-installation construction can be carried out to shorten the construction period in advance.

[0022] 6. From the center of the bin to the bin wall direction, the height of the radial partitions gradually increases. The angle between the device roof and the bin bottom plane is θ, 0° ≤ θ ≤ 60°. For storing different grain varieties, the angles are different, which is convenient for the use of grain storage bins for storing various grain types.

[0023] 7. Slots are opened at the upper position of the radial partitions and vertical beams are arranged longitudinally. At the non-slotted positions above both sides of the radial partitions, corbels are arranged. The top elevation of the corbels is equal to the bottom elevation of the roof. Through the arrangement of the corbels, the air device for mechanical ventilation is lifted as a whole, without changing the air flow path of the original mechanical ventilation corridor, ensuring the normal use of mechanical ventilation during the entire grain storage process.

[0024] 8. The device roof is made of cast iron or steel plate. The roof is a semi-elliptical surface and is installed on the radial partitions through a fixing device. The surface of the semi-elliptical roof is smooth, and the angle formed by it and the bin bottom plane meets the condition requirements for grain self-sliding. The lower part of the semi-elliptical roof is supported by a mesh structure composed of vertical beams and radial partitions. On the one hand, it makes the roof, vertical beams, radial partitions and circumferential partitions form a whole, making the force on the roof more reasonable. Moreover, each part component of the device is a precast block, improving the assembly rate of the structure, reducing the construction of the bin bottom operation, and making the construction simpler and faster.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0033] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, and it can be directly on another element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to another element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners

[0034] Please refer to Figures 1 - 5 , in the embodiment of the present invention, an integrated device for multi-functional circular bulk grain storage bin bottom with assembled full ventilation and grain discharging, is arranged in a semi-elliptical shape, includes a top plate 1 and a bottom plate 5 connected to the top plate 1, and a strengthening structure and a full ventilation system are provided between the top plate 1 and the bottom plate 5, and a discharging auxiliary structure is also adapted to the bin bottom

[0035] Among them, the top plate 1 is a frame structure, and the smallest unit is a quadrilateral area surrounded by two adjacent radial partitions 2 and vertical 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

[0036] The consolidation structure includes radial partitions 2 and vertical beams 3 disposed between the top plate 1 and the bottom plate 5. The height of the radial partitions 2 gradually increases from the bin center to the bin wall. The vertical beams 3 and the radial partitions 2 are cross-welded to form a grid-shaped configuration.

[0037] Furthermore, the radial partitions 2 are made of plastic or steel plates. Slots are opened at the upper positions of the radial partitions 2 and the vertical beams 3 are arranged longitudinally. Corbels 13 are arranged at the non-slotted positions above both sides of the radial partitions 2. The top elevation of the corbels 13 is equal to the bottom elevation of the top plate 1.

[0038] Still further, the vertical beams 3 are made of plastic plates or steel plates. The vertical beams 3 are arranged longitudinally at the slotted positions above the radial partitions 2. The vertical beams 3 are fixed to the top plate 1 and the radial partitions 2 by welding. The height of the vertical beams 3 depends on the height of the semi-elliptical surface top plate 1 of the grain discharging device. At the same time, the height of the radial partitions 2 gradually increases from the bin center to the bin wall. The vertical beams 3 and the radial partitions 2 are cross-welded to form a grid-shaped configuration. In this way, a support with a certain angle is formed, providing a basis for the construction of the inclined top plate. Thus far, the top plate 1, the radial partitions 2, the vertical beams 3, the circumferential partitions 1401 and the bottom plate 5 form an integral whole, constituting the force-bearing structure of the entire grain discharging device and also the framework of the entire device.

[0039] Secondly, the corbels 13 are made of plastic or steel plate materials and are welded to certain positions above both sides of the radial partitions 2. The top elevation of the corbels 13 is equal to the height of the top plate 1. The radial partitions 2 mainly bear the pressure from the corbels 13, enabling the corbels 13 to bear the grain pressure from the top plate 1. Thus, the structural stability of the entire equipment is maintained.

[0040] In addition, the top plate 1 is made of cast iron or steel plate materials and is installed on the radial partitions 2 through the fixing device 15. The corbels 13 between the radial partitions 2 provide support for the installation of the top plate 1.

[0041] The sieve plate 12 is made of stainless steel material, covered and fixed on the top plate 1. The opening ratio of the sieve plate 12 is 30%, and the opening size is limited to be smaller than the minimum particle size of the stored grains.

[0042] The bottom plate 5, the radial partitions 2, the circumferential partitions 1401 and the vertical beams 3 are integrally formed by welding, and there is a certain angle between their top surfaces and the bottom of the granary bin, and the angle size is θ, and 0° ≤ θ ≤ 60°.

[0043] During actual implementation, the bin wall is a concrete bin wall 4. The discharging auxiliary structure is adapted to the grain discharging port 6, and the bin bottom is a reinforced concrete surface 9.

[0044] Please refer to Figure 1 、 Figures 3 - 5 and Figure 6 In Embodiment 2 of the present utility model, a new type of multi-functional circular bulk grain bin bottom prefabricated full-ventilation multi-point grain discharging integrated device. Different from Embodiment 1 of the present utility model, the diameter of the circumferential beam 1402 gradually increases from the bin center to the bin wall. The circumferential beam 1402 and the radial partition 2 are cross-welded to form a grid-shaped configuration.

[0045] Furthermore, the circumferential beam 1402 is made of plastic board or steel plate. The circumferential beam 1402 is fixed to the top plate 1, the radial partition 2 and the circumferential partition 1401 by welding. At the same time, the diameter of the circumferential beam 1402 gradually increases from the bin center to the bin wall. The circumferential beam 1402 and the radial partition 2 are cross-welded to form a grid-shaped configuration. In this way, a support with a certain angle is formed, providing a basis for the construction of the inclined top plate.

[0046] Furthermore, the radial partitions 2 are arranged radially. At the end close to the bin wall, the intersection with the bin wall is denoted as the intersection point. The included angle between the two straight lines formed by connecting the two adjacent intersection points to the center of the bin floor plan is a, and 4° ≤ a ≤ 10°. At the end of the radial partition close to the bin center, it intersects with the edge of the grain discharging system. The extension lines of all the radial partitions intersect at the center of the bin floor plan.

[0047] The top plate 1, the radial partition 2, the circumferential beam 1402, the circumferential partition 1401 and the bottom plate 5 form a whole, constituting the force-bearing structure of the entire grain discharging device and also the framework of the entire device.

[0048] In summary, the beneficial effects of the present utility model are as follows:

[0049] 1. The surface of the top plate is smooth, and the friction generated with the grain particles is small, enabling the grain particles to slide down by their own gravity and complete grain discharging through the grain discharging port;

[0050] 2. The ventilation system is arranged between the radial partitions, forming a full-ventilation system, eliminating the original air duct setting and making the mechanical ventilation process faster and more effective;

[0051] 3. The vertical beam and the vertical partition are fixed by welding, and the radial partition positions the entire device and the bin bottom plane;

[0052] 4. The radial partition and the vertical beam are welded to each other to form a cross-grid structure, making the interior of the entire device in a space form, saving materials, accelerating the overall construction speed, and further shortening the construction period;

[0053] 5. The device partition and top plate can be produced standardized in the factory. The processing and manufacturing quality can be effectively controlled, energy-saving and environmental-friendly. The prefabricated products are assembled on-site, greatly reducing the on-site construction intensity. At the same time, the mechanization degree is increased, the on-site personnel allocation is reduced, the labor cost is saved, and the cross-installation construction can be carried out to shorten the construction period.

[0054] 6. From the center of the bin to the bin wall direction, the height of the radial partition and the diameter of the vertical beam gradually increase. The angle between the device top plate and the bin bottom plane is θ, 0° ≤ θ ≤ 60°. For storing different grain varieties, the angles are different, which is convenient for the use of grain storage bins for various grain types.

[0055] 7. Slots are opened at the position above the radial partition and the vertical beams are arranged in a continuous length. At the positions above both sides of the radial partition where there are no slots, corbels are arranged. 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 lifted as a whole, without changing the air flow path of the original mechanical ventilation corridor, ensuring the normal use of mechanical ventilation during the entire grain storage process.

[0056] 8. The device top plate is made of cast iron or steel plate. The top plate is a semi-elliptical surface and is installed on the radial partition through a fixing device. The surface of the semi-elliptical surface top plate is smooth, and the angle formed by it and the bin bottom plane meets the condition requirements for grain self-flow. The lower part of the semi-elliptical surface top plate is supported by a reticular structure composed of vertical beams and radial partitions. On the one hand, it makes the top plate, vertical beams, radial partitions and circumferential partitions form a whole, making the force on the top plate more reasonable. Moreover, each component of the device is a precast block, improving the assembly rate of the structure, reducing the construction of the bin bottom operation, and making the construction simpler and faster.
