Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically a multi-layer ventilated storage unit for grain drying. Background Technology

[0002] This device is suitable for centralized drying of grains such as wheat, corn, and rice after harvest, and is especially suitable for grain depots or agricultural cooperatives with an annual processing capacity of over 5,000 tons. Traditional grain drying equipment has the following problems: First, it is mostly a single-layer structure, with a large thickness of grain pile, making it difficult for hot air to penetrate the central area, resulting in uneven drying and large differences in moisture content within the same batch of grain; second, the air intake and exhaust channels are single, resulting in uneven airflow distribution and low drying efficiency; third, the feeding and discharging are concentrated at both ends of the silo, making layered operation impossible, causing the grain dried first to be over-dehydrated while the grain dried later still contains moisture, affecting storage stability. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layer ventilated storage chamber for grain drying.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer ventilated silo for grain drying, comprising a grain silo body, an air intake assembly on the grain silo body, the air intake assembly comprising an annular pipe, a first connecting pipe connected to the lower side of the annular pipe, a partition connected to the lower side of the first connecting pipe, an air intake pipe on the partition, a first flange connected to one side of the annular pipe, an air intake connecting pipe connected to one side of the first flange, and a first valve on the air intake connecting pipe.

[0005] As a further description of the above technical solution:

[0006] The grain silo body is equipped with an exhaust assembly, which includes a second connecting pipe. One end of the second connecting pipe is connected to an exhaust connecting pipe, and a second valve is installed on the second connecting pipe.

[0007] As a further description of the above technical solution:

[0008] The grain silo body is connected to an inner feed pipe, one end of which is connected to a second flange, and one side of the second flange is connected to a feed connection pipe.

[0009] As a further description of the above technical solution:

[0010] The annular pipe is fixedly installed on the grain silo body. The annular pipe is connected to the first flange through an extension pipe. The air inlet connection pipe is located on the side of the first flange away from the annular pipe.

[0011] As a further description of the above technical solution:

[0012] The first valve is fixedly installed on the air inlet connecting pipe, the partition is fixedly installed on the inner side of the grain silo body, the air inlet pipe passes through the partition and connects to the first connecting pipe, and the first connecting pipe is provided in multiple sets and evenly distributed on the lower side of the annular pipe.

[0013] As a further description of the above technical solution:

[0014] The feed pipe is fixedly installed at the middle of the inner side of the grain silo body, the second flange and the feed connection pipe are installed on the upper side of the grain silo body, the partition is fixedly installed on the outer side of the feed pipe, and the feed pipe and the partition are provided with a discharge port at the interval.

[0015] As a further description of the above technical solution:

[0016] The vent pipe is fixedly connected to the grain silo body, and the second valve is located at the end of the second connecting pipe away from the vent pipe.

[0017] This utility model has the following beneficial effects:

[0018] 1. The grain silo is divided into independent drying spaces by partitions. With the evenly distributed air inlet pipes and layered air outlets, hot air forms a uniform airflow in each space, reducing the deviation of grain moisture content and solving the problem of uneven drying in traditional equipment. The annular air inlet and layered exhaust structure form a through airflow, improving heat utilization and greatly increasing drying efficiency.

[0019] 2. Layered material distribution is achieved by passing through the feed pipe through each layer of partitions. The discharge port corresponds to each partition, and the discharge of each layer can be controlled independently to meet the drying requirements of different batches of grain. The first valve and the second valve adjust the air intake and exhaust volume respectively, and the drying parameters can be flexibly adjusted according to the type of grain. The flange connection of the feed and air intake structure facilitates docking with feeding equipment and hot air furnace, improving the ease of operation. Attached Figure Description

[0036] Example 2:

[0037] Specifically, the annular pipe 11 is fixedly installed on the grain silo body 3, and the annular pipe 11 is connected to the first flange 15 through an extension pipe. The air inlet connection pipe 16 is located on the side of the first flange 15 away from the annular pipe 11.

[0038] In this embodiment, the annular pipe 11 is a galvanized steel pipe, which is fixed to the inner wall of the grain silo by three supports; the extension pipe is a short pipe of the same material, one end of which is tangentially connected to the annular pipe 11, and the other end is welded to the first flange 15; the first flange 15 is a PN10 standard flange, and the air inlet connection pipe 16 is a galvanized steel pipe, one end of which is connected to the first flange 15, and the other end is connected to the hot air furnace.
