Description

Technical Field

[0001] This invention relates to the field of grain storage engineering technology, and in particular to a large-span, tall, flat warehouse. Background Technology

[0002] Flat warehouses are currently the most commonly used type of grain storage. With the development of the industry, the grain stacking height of flat warehouses is also getting higher and higher. At present, the grain loading height of tall flat warehouses can reach 7-8 meters. They have high grain stacking, large storage capacity, and small footprint, and are increasingly widely used in the fields of grain storage and logistics.

[0003] Because of the large capacity of flat warehouses, the temperature, humidity and gas composition of grain piles can be altered by external temperature and humidity, as well as by the heat generated by respiration and metabolism. These factors directly affect the safety of stored grain. Therefore, heat insulation and ventilation in tall flat warehouses are crucial.

[0004] For single-story warehouses, roof insulation is typically achieved through the roof structure, which is generally an arched roof, where the upper chord is an arched slab and the lower chord is a flat plate, with ventilation holes providing airflow in the space between them. Alternatively, prestressed concrete folded linear trusses and large roof panels, or prestressed concrete double-T slabs, may be used. However, these roof structures are not well-suited for larger span single-story warehouses. Furthermore, the most common ventilation and cooling method for tall, single-story warehouses is vertical ventilation, where air enters through ventilation ducts at the bottom and exits through vents at the top. However, for large-span, high-capacity tall, single-story warehouses, the ventilation effect needs further improvement. Summary of the Invention

[0005] In view of this, the purpose of this invention is to address the shortcomings of the prior art by providing a large-span flat warehouse with a ventilation mode that uses circulating airflow and upper-level exhaust ventilation, resulting in high roof stability and good overall ventilation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A large-span, tall, single-story warehouse includes a warehouse body, the upper part of which is a floor, the top of which is a roof, and a mezzanine is formed between the floor and the roof. Ventilation openings two and three are evenly arranged on the lower and upper outer periphery of the mezzanine. The center of the roof is Roof 1 with a broken cross-section, and the outer side of Roof 1 is Roof 2 with a sloping roof. The bottom of the silo is equipped with a ground ventilation cage, and three ventilation openings are evenly arranged on the lower two side walls of the silo, while one ventilation opening is evenly arranged on the upper part above the grain loading line.

[0007] Furthermore, support piles are evenly arranged on the central axis of the bottom of the silo, and the ground ventilation cages are symmetrically distributed on both sides of the support piles.

[0008] Furthermore, the ground ventilation cage includes a main air duct and a U-shaped pipe connected to it, and the three ventilation openings correspond to and are connected to the main air duct.

[0009] Furthermore, ventilation openings four are evenly arranged on the upper part of the silo between two ventilation openings one, and a circulating fan is installed outside the silo. The circulating fan is connected to one ventilation opening four and two ventilation openings three below it through a duct.

[0010] Furthermore, thin walls one and two are symmetrically arranged between the floor and the roof, ventilation openings two are evenly arranged on the outer wall of the interlayer, and ventilation openings three are evenly arranged circumferentially on the upper part of thin wall two above the pitched roof two.

[0011] Furthermore, a scraper conveyor is arranged between thin-walled section one and thin-walled section two in the mezzanine, and a grain inlet is set on the floor corresponding to the outlet of the scraper conveyor.

[0012] Furthermore, ladders are arranged on both the horizontal and vertical outer sides of the warehouse, and an entrance door is arranged on the platform at the top of the ladder.

[0013] Furthermore, an axial flow fan is installed at intervals around the ventilation opening.

[0014] The beneficial effects of this invention are: 1. This invention discloses a large-span, tall, flat warehouse with a large span and large capacity. To ensure the quality of the grain pile, the warehouse adopts a ventilation mode of circulating air and strong exhaust from the upper layer of the warehouse. The top of the warehouse is arranged with two rows of ventilation openings, which can realize ventilation and cooling inside the warehouse.

[0015] Ventilation opening 1 is evenly arranged on the outer wall of the silo above the grain loading line, with axial flow fans spaced apart inside ventilation opening 1. Ventilation opening 4 is evenly arranged on the upper part of the silo between two ventilation openings 1. A circulating fan is arranged below ventilation opening 4, and the circulating fan is connected to one ventilation opening 4 and two ventilation openings 5 ​​below it through air ducts. That is, two sets of ground ventilation cages, one ventilation opening 4, one circulating fan, and the air duct outside the silo form a circulating ventilation system. Its operating principle is: the air above the grain pile and above the grain surface is drawn out by the circulating fan, passes through the air duct outside the silo, and enters the ground ventilation cage 6 and rises into the grain pile, thus forming a circulation. This not only ventilates and cools the grain, but also helps to achieve synchronous consistency of grain temperature and moisture in the grain pile inside the silo, ensuring stable grain quality. In addition, the axial flow fan on ventilation opening 1 strongly draws in and exhausts air, further realizing ventilation and cooling of the grain pile.

[0016] 2. Due to the large span of the flat warehouse, the roof adopts a combination of two types of roofs. The center of the roof is Roof 1 with a zigzag cross-section and a slope of 5%. The outer perimeter has a larger slope. The middle is stably supported by Thin Wall 1 and Thin Wall 2. There are also two layers of ventilation openings, which have excellent heat insulation and ventilation effects. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0020] like Figure 1-5 As shown, a large-span, tall, flat warehouse includes a warehouse body 1 with a horizontal span of 39m, a vertical span of 123.6m, a grain pile height of 8.5m, and a warehouse capacity of 30,000 tons (based on wheat). It has four storage rooms inside, with a floor 2 on top and a roof 3 on top of the floor 2. Thin-walled sections 10 and 11 are symmetrically arranged between the floor 2 and the roof 3, providing high stability. A mezzanine 4 is formed between the floor 2 and the roof 3.

[0021] Because of the large span of this tall, single-story warehouse, the roof 3 is a combination of two roofs. The central roof is a zigzag roof 31 with a 5% slope, and the two sides are sloping roofs 32. Ventilation openings 8 are evenly distributed on the outer wall of the mezzanine 4, and circumferentially evenly distributed ventilation openings 9 are located above the sloping roofs 32 on the upper part of the thin-walled roof 11. Therefore, the entire warehouse roof structure has strong stability and excellent ventilation and heat insulation effects.

[0022] Support piles 5 are evenly arranged along the central axis of the bottom of the silo 1. Ground ventilation cages 6 are evenly distributed on both sides of the support piles 5 at the bottom of the silo 1, effectively creating four sets of ground ventilation cages in one silo. This design facilitates maintenance. The ground ventilation cage 6 includes a main air duct 61 and a U-shaped pipe 62 connected to it. Ventilation openings 5 ​​17 are arranged on the outer wall of the silo 1 at positions corresponding to the main air duct 61 of the ground ventilation cage 6, and the main air duct 61 connects to the ventilation openings 5 ​​17.

[0023] Additionally, ventilation openings 1-7 are evenly arranged on the outer wall of the silo body 1 above the grain loading line, with axial flow fans intermittently connected to them. Ventilation openings 4-15 are evenly arranged on the upper part of the silo body 1 between the two ventilation openings 1-7. Circulating fans 18 are evenly installed outside the silo body 1, and the circulating fans 18 are connected to one ventilation opening 4-15 and two ventilation openings 5-17 below it through air ducts. This is equivalent to two sets of ground ventilation cages, one ventilation opening 4-15, and one circulating fan 18 forming an internal circulation ventilation system. That is, this application is a circulating internal circulation and axial flow fan forced exhaust ventilation mode on the upper ventilation openings 1-7. In the circulating internal circulation, the air above the grain pile and above the grain surface is drawn out by the circulating fan 18 and enters the ground ventilation cage 6 through the air duct outside the silo, and then enters the grain pile upwards, thus forming an internal circulation. This internal circulation can ventilate and cool down, and also achieve synchronous consistency of grain temperature and grain moisture, ensuring stable grain quality. In addition, the axial flow fans on some of the ventilation openings 1-7 forcefully draw in and exhaust air, further realizing ventilation and cooling of the grain pile. Alternatively, depending on the actual situation, an air conditioner can be connected to the internal circulation ventilation system to increase the cooling effect.

[0024] In addition, the inbound and outbound system of this application adopts a fully automatic inbound and outbound system. The inbound scraper 12 is arranged between the thin-walled first 10 and the thin-walled second 11 in the mezzanine. The grain inlet 16 is set at the position corresponding to the outlet of the inbound scraper 12 on the floor 2 to realize automatic inbound.

[0025] In addition, to ensure convenient maintenance, ladders 13 are arranged on the outer sides of the warehouse 1 in both the horizontal and vertical directions. The top platform of the ladders 13 is equipped with an entrance door 14 to facilitate the entry of workers into the warehouse.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
