Description

Technical Field

[0001] This utility model relates to the technical field of grain storage silos, and in particular to a green and energy-saving double-layered silo. Background Technology

[0002] Grain silos are essential facilities for storing grains and other agricultural products, playing an irreplaceable role in ensuring national food security and regulating market supply and demand. With the continuous growth of my country's grain production, the demand for grain storage is also constantly increasing. This not only presents significant challenges to the grain storage industry but also places higher demands on the design of grain silos, especially in terms of green and energy-saving features.

[0003] Currently, the increase in my country's grain production has put enormous pressure on the grain storage sector, and has also placed higher demands on the green and energy-saving aspects of grain silos. Grain silos are widely distributed throughout the country, and due to differences in local environments and the types of grains to be stored, grain depots in different regions have increasingly higher requirements for the green and energy-saving aspects of grain silos.

[0004] Meanwhile, existing grain silos mainly adopt a single-layer roof structure. These silos suffer from problems such as heat accumulation from solar radiation in the summer and leakage during the rainy season, resulting in high energy consumption and low grain storage safety; the exposed equipment on the roof increases equipment maintenance costs; and the conical roof makes it impossible to install photovoltaic applications for clean energy. Utility Model Content

[0005] In view of the current problems of inconvenient maintenance and high energy consumption for ventilation and cooling of single-layer roof structures of grain silos, this utility model provides a green and energy-saving double-layer roof silo.

[0006] The solution adopted by this utility model to solve its technical problem is as follows: a green and energy-saving double-layered silo, including a silo body and a silo top, the silo top being fixed to the top of the silo body, and also including a U-shaped silo top cover, the U-shaped silo top cover being located above the silo top, with multiple columns evenly arranged on the silo top to support the U-shaped silo top cover, the outer edge of the U-shaped silo top cover being provided with an outer wall, the outer wall being connected to the wall of the silo body, and windows being provided on the outer wall of the U-shaped silo top cover to facilitate air circulation inside the U-shaped silo top cover; a corridor and a maintenance and equipment placement platform are provided in the interlayer between the U-shaped silo top cover and the silo top, and a grain inlet conveying device is installed inside the U-shaped silo top cover, the unloading port of the grain inlet conveying device being connected to the grain inlet on the silo top through a pipe, and a multi-point feeding device is installed below the grain inlet on the silo top.

[0007] Furthermore, the upper surface of the convex-shaped warehouse roof is covered with photovoltaic panels.

[0008] Furthermore, the silo top has a conical structure, with a silo top platform at the center of the conical structure. Two to four mechanical ventilation openings are evenly arranged on the silo top platform, and four natural ventilation openings are evenly arranged on the conical surface of the silo top. Ventilation pipes are connected to the natural ventilation openings and mechanical ventilation openings, and the ventilation pipes pass through the U-shaped silo top cover to communicate with the outside.

[0009] Furthermore, the pillars are concrete pillars, with four concrete pillars installed on the top platform of the silo to support the U-shaped silo top cover.

[0010] Furthermore, the windows include ventilation louvers and skylights. Multiple ventilation louvers and skylights are provided on the outer wall of the U-shaped warehouse roof to facilitate air circulation inside the U-shaped warehouse roof and reduce heat accumulation inside the roof.

[0011] Furthermore, a ring corridor is provided on the outside of the silo body, and the ring corridor is located at the top of the silo body.

[0012] Furthermore, the multi-point distribution equipment includes a grain receiving port, grain channels, and grain dispersing cones. The grain receiving port is connected to the grain inlet at the center of the U-shaped silo top cover, serving as the grain inlet for the multi-point distribution equipment. Multiple grain channels extending towards the silo wall are evenly installed on the lower outer side of the grain receiving port. The grain dispersing cone is fixed at the bottom center of the grain receiving port. Grain enters the grain receiving port from the grain inlet, and the grain dispersing cone causes the grain to scatter in all directions and enter the grain channels. The grain channels are inclined downwards, so that the grain falls along the grain channels to all sides of the silo body, achieving uniform distribution of grain.

[0013] The beneficial effects of this utility model are as follows: The green and energy-saving double-layer top silo provided by this utility model can effectively save energy, is easy to maintain, and generates static electricity, thereby improving the green and energy-saving level of grain silos.

[0014] A maintenance and equipment placement platform is located on the top of the silo, which can be used for personnel maintenance and placement of ventilation equipment, effectively ensuring personnel safety and improving equipment maintenance efficiency. Photovoltaic panels enable photovoltaic power generation, contributing to environmental protection and energy conservation. The double-layered roof structure, consisting of the silo roof and a U-shaped roof cover forming a sealed space, provides rain protection and heat insulation. Windows are located around the perimeter of the cover; opening these windows allows for air convection and heat dissipation, reducing energy consumption. The windows are located 1.1m above the top axis and are evenly distributed circumferentially to achieve internal circulation, making ventilation and cooling more effective.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below.

[0021] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a green and energy-saving double-layered silo. The green and energy-saving silo structure consists of a silo body 1, a silo roof 2, and a U-shaped silo roof cover 3, which are stacked sequentially from bottom to top. The silo roof 2 has a conical structure with a platform surface at its center. Two to four mechanical ventilation openings 902 are evenly arranged on the platform surface, and four natural ventilation openings 901 are evenly arranged on the conical surface of the silo roof 2. Ventilation pipes 9 are connected to the natural ventilation openings 901 and the mechanical ventilation openings 902. The ventilation pipes 9 pass through the U-shaped silo roof cover 3 and connect to the outside. One end of the ventilation pipe 9 connects to the inside of the silo, and the other end extends to connect to the outside of the silo. The outlet at the end located outside the silo is bent downwards to prevent rainwater, debris, etc., from falling into the pipe.

[0022] Specifically, the U-shaped silo top cover 3 has a protruding central circular platform in the middle, and an outer ring platform on the outside of the central circular platform. The height of the ring platform is lower than that of the central circular platform, and the outer edge of the ring platform is flush with the outer surface of the silo body. Thus, the interior of the U-shaped silo top cover 3 is divided into two layers: a lower air convection layer and an upper equipment corridor layer, which is the layer for grain conveying equipment. The outer edge of the U-shaped silo top cover 3 is provided with an outer wall, which is connected to the wall of the silo body 1. Windows 7 are provided on the outer wall of the U-shaped silo top cover 3 to facilitate air circulation inside the U-shaped silo top cover 3.

[0023] Photovoltaic power generation panels 5 are installed on the central circular platform and the ring platform. The photovoltaic power generation panels 5 generate electricity to meet the power needs of the silo-related equipment, reduce the energy consumption of the silo, and achieve the goal of green and low-carbon environmental protection.

[0024] The windows 7 include ventilation louvers and skylights. Multiple ventilation louvers and skylights are installed on the outer wall of the U-shaped silo roof 3 to facilitate air circulation within the roof 3 and reduce heat accumulation. The ventilation louvers and skylights are located 1.1m above the upper axis of the silo body and are evenly distributed in a circular pattern to achieve internal circulation, making the ventilation and cooling effect more significant, facilitating air circulation, reducing heat accumulation within the cavity, and reducing energy consumption for grain temperature control.

[0025] Four columns 6 are evenly arranged on the top of the silo 2, supporting the U-shaped silo top cover 3. The columns 6 are concrete columns, and the four concrete columns are set on the silo top platform to support the U-shaped silo top cover 3.

[0026] The equipment corridor layer of the convex-shaped warehouse top cover 3 is equipped with a corridor and a maintenance and equipment placement platform 4. The maintenance and equipment placement platform 4 is a vertical cuboid structure, made of concrete pouring and metal plate welding. It can be used for the fixed placement of ventilation equipment such as axial flow fans and ventilation ducts 9, and can also assist maintenance personnel in carrying out maintenance work.

[0027] A circular corridor 10 is provided on the outer side of the silo body 1, located at the top of the silo body 1. The circular corridor 10 is a walkway structure built around the top of the silo for maintenance personnel to walk on, connecting with ladders installed on the outer wall of the silo body 1, facilitating the inspection and maintenance of facilities such as the silo roof and the U-shaped silo roof cover 3. At the same time, the circular corridor 10 can connect to the door installed on the outer wall of the U-shaped silo roof cover 3, facilitating personnel to enter the interior for maintenance.

[0028] The convex-shaped silo top cover 3 is equipped with a grain inlet conveying device. The unloading port of the grain inlet conveying device is connected to the grain inlet on the silo top 2 through a pipe. A multi-point feeding device 8 is installed below the grain inlet on the silo top 2.

[0029] The multi-point feeding device 8 can achieve balanced material distribution at multiple points, reducing the degree of automatic grading and further saving energy consumption for grain ventilation. Figure 3 and Figure 4 As shown, the multi-point distribution equipment 8 includes a grain receiving port 801, grain channels 802, and grain dispersing cones 803. The grain receiving port 801 is connected to the grain inlet 11 at the center of the top of the silo 2, serving as the grain inlet of the multi-point distribution equipment 8. Multiple grain channels 802 extending towards the inner wall of the silo 1 are evenly installed on the lower outer side of the grain receiving port 801. The grain dispersing cone 803 is fixed at the bottom center of the grain receiving port 801. Grain enters the grain receiving port 801 from the grain inlet. The grain dispersing cone 803 causes the grain to scatter in all directions and enter the grain channels 802. The grain channels 802 are inclined downwards, so that the grain falls along the grain channels 802 to the surrounding areas of the silo 1, achieving uniform distribution of grain.

[0030] The grain receiving port 801 is a barrel-shaped structure located at the center of the top of the silo, connected to the grain inlet 11 at the center of the silo top 2. The upper part of the grain receiving port 801 connects with the grain inlet to ensure smooth grain entry; multiple openings are evenly distributed on the side of the barrel wall of the grain receiving port 801, which connect to the grain channel 802 extending towards the wall of the silo body 1. The bottom of the grain receiving port 801 bulges upward in the middle to form an arc, and the apex of the arc is fixed to the grain dispersing cone 803.

[0031] Grain channels 802 extend evenly outward from the side opening of the grain receiving port 801, sloping downwards along the wall of the silo body 1. Each grain channel 802 is an inclined passage designed to guide grain from the grain receiving port 801 to distribute it evenly around the perimeter of the silo body 1. The number and inclination angle of the grain channels 802 can be adjusted according to the size of the silo and grain storage requirements to ensure uniform grain distribution.

[0032] The grain dispersing cone 803 is fixed at the apex of the arc-shaped protrusion in the middle of the bottom of the grain receiving port 801. When grain enters the grain receiving port 801 from the inlet, the grain dispersing cone 803 spreads the grain outwards, allowing it to fall evenly into each grain channel 802. The grain dispersing cone 803 is usually designed in a conical or hemispherical shape with a smooth surface to reduce grain resistance and ensure smooth grain flow.

[0033] Grain enters through the inlet at the top of the silo and then passes through the upper opening of the receiving port 801. The grain entering the receiving port 801 is blocked by the grain dispersing cone 803 and is evenly dispersed in all directions. The design of the grain dispersing cone 803 allows the grain to be dispersed quickly and evenly, avoiding concentration at a certain point. The dispersed grain enters each grain channel 802 through the openings on the side wall of the receiving port 801. The grain channels 802 are set at an angle downwards, and by using gravity, the grain falls along the grain channels 802 to the sides of the silo body 1, and is finally evenly distributed inside the silo.

[0034] With the multi-point feeding device 8, grain can be evenly distributed in the silo, avoiding local accumulation, reducing the degree of automatic grading, and reducing problems such as clumping and overheating caused by excessive local density of grain. The evenly distributed grain helps to improve the storage efficiency of the silo, make full use of the storage capacity, and reduce waste. Traditional single-point feeding methods often require additional mechanical devices to assist in distribution, while the multi-point feeding device 8, through reasonable structural design, can achieve even distribution by using gravity and natural flow, reducing energy consumption. The design of the grain cone 803 and the grain channel 802 is simple and reliable, reducing the use of mechanical parts, lowering maintenance costs and failure rate. This equipment is suitable for silos of different specifications and types, and the number and inclination angle of the grain channel 802 can be adjusted according to actual needs, showing strong adaptability and flexibility.

[0035] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
