Description

[Detailed description of the invention] The present invention relates to improvements in stationary grain drying equipment.

In general, in stationary grain drying equipment, the floor of the drying equipment is formed with a porous wall because it is necessary to supply drying hot air over a wide area, and the drying hot air ejected from the porous wall on the floor is used to dry the grain layer. Grain was dried by aeration, and the exhaust air was released into the top opening of the drying device, but in this case, dust was also blown out from the top opening of the drying device along with the exhaust air, causing dust to flow into the vicinity of the device. Dust was scattered and accumulated on the floor, deteriorating the environment in the workplace.

For the purpose of preventing dust from scattering in the workplace, for example, as disclosed in Japanese Patent Application Laid-Open No. 131837/1983,
The pressure air blown out from the upper side wall of the grain storage chamber is made to cross this grain storage chamber and guided to the guide wall provided inside the roof of the grain storage chamber, and then the pressure air is directed outside the roof. A grain storage room structure has been proposed that allows dust to be discharged, but although this can prevent dust from scattering into the room, it is designed to discharge dust to the outside through the roof. However, there was a problem in that the dust scattered outside the building could not be collected, deteriorating the surrounding environment.

In the present invention, on one side of the drying building where stationary drying rooms are arranged in parallel through a central passage, a dust collection room with an internal bag filter and a ventilation room with an internal blower are installed vertically. By constructing ancillary buildings in succession and horizontally connecting the ventilation passages equipped with ventilation fans at the top of the passageway, the ventilation equipment can be simplified and its manufacturing cost can be reduced. At the same time, it is an object of the present invention to develop and provide a device that facilitates maintenance and management, prevents scattering of dust and generation of high noise, and maintains a good working environment at all times.

To explain the present invention with reference to an embodiment diagram, reference numeral 1 in the diagram is a floor section on which an air sweep floor is installed;
The upper part is a grain tank 2 and the lower part is a ventilation chamber 3 to integrally form a stationary drying chamber 4, and the drying chambers 4 are arranged in parallel via a central passage 5 to form a drying building 6.
On one side of the drying building 6, the upper part thereof is a dust collection room 7,
An auxiliary building 9 with a ventilation chamber 8 at the bottom is provided and connected.

Then, an air exhaust passage 11 is horizontally installed in the upper part of the central passage 5, with ventilation walls 10, 10 on both sides and communicating with the upper side of each of the grain bins 2. An exhaust fan 12 is installed in the chamber, one end of which is connected to a bag filter 13 provided in the dust collection chamber 7, and each of the ventilation chambers 10, 10 is connected to the ventilation chamber 8.
It is connected via each air outlet 15 to an air blower 14 provided in the air conditioner.

The drying building 6 also has an elevator 1 on the other side.
6 are erected and communicated with each input port 17 at the top of each grain tank 2 by a belt conveyor 18 that rotates in forward and reverse directions, and the input port 17 is provided with a rotating distribution disk 19.
A belt conveyor 20 is installed horizontally on the road of the central passage 5 and communicates with the grain tank floor 1 on both sides through a discharge gutter 21, so that the dried grains in the grain tank 2 can be transported and discharged. 22 is a ventilation window provided on the wall of the dust collection chamber 7, and 23 is a ventilation window provided on the wall of the ventilation chamber 8.

With the above configuration, the raw grain is transferred to the elevator 16.
When the fans 12 and 14 of the apparatus are rotated, the drying air generated by the blower 14 in the annex 9 passes through each ventilation chamber 3 and reaches the floor 1. The air blows out through the installed air sweep floor and rises, passing through the grain layer formed in the grain tank 2 and drying the grains. The air is sucked by the exhaust fan 12 installed in the exhaust passage 11,
Further, the air flows into a bag filter 13 provided in a dust collection chamber 7 connected to the air passage 11, where the dust is removed by the filter 13, and the clean exhaust air is discharged to the outside through an air exhaust window 22. Further, the dried grains are timely conveyed in flight by the blasts of the air sweep floor, flow out from the discharge gutter 21 onto the belt conveyor 20, and are carried outside to be entrusted to the next process.

In short, the present invention provides a drying building in which stationary drying rooms each having a grain tank at the top and a ventilation chamber at the bottom and an air sweep floor on the floor are arranged in parallel via a central passage. A structure in which an annex is provided on one side with an upper part serving as a dust collection room and a lower part serving as a ventilation room, which are connected to each other, and an air exhaust passage is provided above the central passageway with ventilation walls on both sides and communicates with the grain bin. A ventilation fan is installed in the ventilation passage, one end of which is connected to a bag filter provided in the dust collection chamber, and each of the ventilation chambers is connected to a blower provided in the ventilation chamber. Since the main feature is a static grain drying equipment, compared to conventional equipment in which each static drying room is equipped with an air supply/exhaust system, the drying building has an air exhaust passage above the central passage, which allows air to be collected vertically. Since it has a structure in which attached buildings with overlapping dust rooms and ventilation rooms are installed, the structure of the air supply/exhaust system is simplified and its production costs are reduced, and its maintenance and management are simplified, making it possible to separate attached buildings. In addition to installing a blower inside, the dust-laden wind collected by the exhaust passage equipped with the blower is removed and discharged by the bag filter in the dust collection room, so the area around the device is always kept clean, and This has the effect of eliminating noise pollution by muffling high noise on the exhaust side with a bag filter, and making the installation environment of this device always favorable.
