Description

Technical Field

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

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

[0003] In general, the existing shallow silo has a grain inlet at the center of the silo top, and the grain is fed into the silo through a submerged scraper conveyor on the silo top. A conveying corridor is arranged at the bottom of the silo, and grain discharge openings are opened on the bottom floor of the silo along the direction of the corridor. When discharging grain, the grain discharge opening 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 lack of inclination or small inclination of the bottom plane of the silo, 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 discharging cost without reducing the mechanization level 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. Summary of the Invention

[0005] The purpose of the utility model is to provide a novel multi-functional integral device for assembled ventilation and multi-point grain discharging at the bottom of a circular bulk grain bin to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Design a novel multi-functional integral device for assembled ventilation and multi-point grain discharging at the bottom of a 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 strengthening structure is arranged between the top plate and the bottom plate;

[0008] Among them, rectangular holes are opened on both the top plate and the bottom plate above the ventilation corridor at the bottom of the bin, and the rectangular holes are adapted to the ventilation corridor at the bottom of the bin;

[0009] Preferably, the strengthening structure includes radial partitions and vertical partitions arranged between the top plate and the bottom plate. The height of the vertical partitions gradually increases from the center of the bin to the bin wall. The vertical partitions and the radial partitions are cross-welded to form a grid-shaped configuration.

[0010] Preferably, the radial partition and the vertical partition are made of plastic plates or steel plates. The radial partition and the vertical partition are connected by welding to form a grid-shaped stress structure with a certain angle, providing a basis for the construction of the inclined roof of the top plate.

[0011] Preferably, the height of the vertical partition gradually increases from the center of the bin to the bin wall, and the height of the vertical partition depends on the height of the inclined roof of the grain discharging distributor.

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

[0013] Preferably, the radial partition and the vertical partition 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 is θ, and 0° ≤ θ ≤ 60°.

[0014] Preferably, corbels are arranged longitudinally between the two side partitions of the ventilation corridor. The top elevation of the corbel is lower than the top plate by a certain height and is equal to the bottom elevation of the snap plate. The corbel is made of plastic or steel plate. The elevation of the snap plate is equal to the elevation of the corresponding position of the top plate, and the sizes of the embedded angle steels at the upper edge of the ventilation corridor are equal.

[0015] The present utility model provides a novel multi-functional circular bulk grain bin bottom assembled ventilation multi-point grain discharging integrated device, and the beneficial effects are as follows:

[0016] 1. The surface of the top plate is smooth, and the friction force 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;

[0017] 2. The vertical partition is fixed to the top plate and the radial partition by welding, and the vertical partition positions the whole device and the bottom plane of the bin;

[0018] 3. The radial partition and the vertical partition are welded to each other to form a cross-grid structure, making the interior of the whole device in a space form, saving materials, accelerating the overall construction speed, and further shortening the construction period;

[0019] 4. The device partitions and the top plate can be standardized and produced in the factory. The processing and manufacturing quality can be effectively controlled, energy-saving and environmental-friendly; the prefabricated finished 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 configuration is reduced, the labor cost is saved, and the cross-installation construction can be carried out to shorten the construction period in advance;

[0020] 5. From the center of the bin towards the bin wall, the heights of the radial partitions and the vertical partitions gradually increase. The angle between the top plate of the device and the bottom plane of the bin is θ, where 0° ≤ θ ≤ 60°. For storing different grain varieties, the angle is different, which is convenient for the use of bins for storing various grain types;

[0021] 6. Corbels are provided on both sides of the ventilation corridor and are vertically aligned with the edge of the ventilation corridor. Through the arrangement of the corbels, the air ducts for mechanical ventilation are lifted as a whole, without changing the original air flow path of the mechanical ventilation corridor, 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 plate or steel plate. The top plate is a semi-elliptical surface. The inner side of the top plate intersects with the vertical partition by welding. The surface of the semi-elliptical top plate is smooth, and the angle formed by it and the bottom plane of the bin meets the requirements for the self-flow of grains. The lower part of the semi-elliptical top plate is supported by a mesh structure composed of vertical plastic plates and radial partitions. On the one hand, it makes the top plate, the vertical partitions and the radial partitions form a whole, making the force on the top plate more reasonable. Moreover, each component of the device is a precast block, which improves the assembly rate of the structure, reduces the construction operation at the bottom of the bin, and makes the construction simpler and faster.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other 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 the other 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 manner.

[0035] Please refer to Figures 1 - 6 , in the embodiment of the present invention, an integrated device for multi-functional circular bulk grain bin bottom with assembled ventilation and multi-point grain discharging is symmetrically semi-elliptical, including a top plate 1 and a bottom plate 5 connected to the top plate 1, and a strengthening structure is provided between the top plate 1 and the bottom plate 5;

[0036] Among them, rectangular holes are opened above the ventilation corridor 9 at the bottom of the bin on both the top plate 1 and the bottom plate 5, and the rectangular holes are adapted to the ventilation corridor 9 at the bottom of the bin.

[0037] The consolidation structure includes radial partitions 2 and vertical partitions 3 provided between the top plate 1 and the bottom plate 5. The height of the vertical partitions 3 gradually increases from the center of the bin to the bin wall. The vertical partitions 3 and the radial partitions 2 are cross-welded to form a grid-shaped configuration.

[0038] Furthermore, the vertical partitions 3 are made of plastic plates or steel plates. The vertical partitions 3 are fixed to the top plate 1 and the radial partitions 2 by welding. The height of the vertical partitions 3 depends on the height of the top plate 1 of the grain discharging device. At the same time, the height of the vertical partitions 3 gradually increases from the center of the bin to the bin wall. The vertical partitions 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.

[0039] Secondly, the bottom plate 5 is raised relative to the bottom surface of the vertical partitions 3. The purpose of raising is to prevent the warping problem of the bottom plate 5 caused by the uneven support surface when the bottom plate 5 is placed. So far, the top plate 1, the radial partitions 2, the vertical partitions 3 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.

[0040] In addition, the two side partitions 15 of the ventilation corridor are made of plastic or steel plates. They are arranged along both sides of the ventilation corridor 9. The height of the two side partitions 15 of the ventilation corridor is determined by lofting. Its thickness is greater than that of the radial partition 2. The specific thickness is calculated according to the size of the ventilation corridor 9. At the same time, the distance between the corresponding corbels 11 between the two side partitions 15 of the ventilation corridor is equal to the designed width size of the ventilation corridor 9. Among them, the corbels 11 are made of plastic or steel plates and are welded longitudinally at a certain position above the two side partitions 15 of the ventilation corridor. The top elevation of the corbels 11 is lower than the top plate 1 by a certain height and is equal to the bottom elevation of the buckle plate 10. It mainly bears the pressure coming from the corbels 11, enabling the corbels 11 to bear the grain pressure from the ventilation trough air device. Thus, maintaining the structural stability of the entire equipment.

[0041] Among them, the buckle plate 10 is mainly used to prevent it from sliding down along the ventilation corridor 9 to the bottom of the bin;

[0042] The top plate 1, the bottom plate 5, the radial partitions 2 and the vertical partitions 3 are formed into a whole by welding. Its top surface has a certain angle with the bottom of the granary, and the angle size is θ, and 0°≤θ≤60°.

[0043] During actual implementation, a reinforced concrete bin bottom 13 is provided at the bottom of the bin, and an underground corridor 7 is formed inside the bin. The bin wall is a concrete bin wall 4. The discharging auxiliary structure is adapted to the grain discharging port 6.

[0044] Please refer to Figures 7 - 9, Embodiment 2 of the present utility model, a multi-functional circular bulk grain storage bin bottom assembled ventilation and multi-point grain discharging integrated device. Different from Embodiment 1 of the present utility model, the diameter and height of the circumferential partition 12 gradually increase from the bin center to the bin wall. The circumferential partition 12 and the radial partition 2 are cross-welded to form a grid-shaped configuration.

[0045] Furthermore, the circumferential partition 12 is made of plastic board or steel plate. The circumferential partition 12 is fixed to the top plate 1 and the radial partition 2 by welding. The height of the circumferential partition 12 depends on the height of the top plate 1 of the grain discharging device. At the same time, the diameter and height of the circumferential partition 12 gradually increase from the bin center to the bin wall. The circumferential partition 12 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 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 plan.

[0047] The top plate 1, the radial partitions 2, the circumferential partitions 12 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 invention are as follows:

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

[0050] 2. The vertical partitions 3 are fixed to the top plate 1 and the radial partitions 2 by welding. The circumferential partitions position the entire device and the bin bottom plane;

[0051] 3. The radial partitions 2 and the vertical partitions 3 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;

[0052] 4. The device partitions and the top plate can be standardized and produced in the factory. The processing and manufacturing quality can be effectively controlled, energy-saving and environmentally friendly; the prefabricated products are assembled on-site, greatly reducing the on-site construction intensity. At the same time, the degree of mechanization increases, reducing the on-site personnel allocation, saving labor costs, and allowing for cross-installation construction to shorten the construction period in advance;

[0053] 5. From the center of the bin towards the bin wall, the heights of the radial partitions and the vertical partitions gradually increase. The angle between the top plate of the device and the bottom plane of the bin is θ, where 0° ≤ θ ≤ 60°. For storing different grain varieties, the angle is different, which is convenient for the use of bins for storing various grain types.

[0054] 6. Corbels are provided on both sides of the ventilation corridor and are vertically aligned with the edge of the ventilation corridor. Through the arrangement of the corbels, the air device for mechanical ventilation is lifted as a whole, without changing the original air flow path of the mechanical ventilation corridor, ensuring the normal use of mechanical ventilation during the entire grain storage process.

[0055] 7. The top plate of the device is made of plastic or steel plate. The top plate is a semi-elliptical surface. The intersection of the inner side of the top plate and the vertical partition is welded. The surface of the semi-elliptical top plate is smooth, and the angle formed by it and the bottom plane of the bin meets the requirements for the self-flow of grains. The lower part of the semi-elliptical top plate is supported by a network structure composed of circumferential plastic plates and radial partitions. On the one hand, it makes the top plate, the vertical partitions, and the radial partitions form an integral whole, making the force on the plastic top plate more reasonable. Moreover, each component of the device is a precast block, which improves the assembly rate of the structure, reduces the construction work at the bottom of the bin, and makes the construction simpler and faster.
