Description
Technical field
The present invention relates to a kind of grain heat-drying dust-extraction units, belong to agricultural machinery technological field.
Background technology
Grain drying is their ability to an essential procedure for secure storage, and the moisture content of grain is from harvesting, storage
To processing whole process in suffer from vital influence, if moisture content is excessively high, be easy to cause grain go rotten it is rotten.Closely
Nian Lai, with the attention that China develops agricultural machinery, grain-production Mechanization Level has obtained quick raising.According to statistics, every year
The standard of safe storage is not achieved after China's grain harvest after it cannot dry either drying due to weather in time makes grain
It is lost caused by going mouldy etc. during storage, processing, drying etc. and accounts for the 5% of total output of grain, economic loss then may be used
To reach 300~60,000,000,000 yuan, but total losses amount is also not achieved 1% after the developed countries such as Japan, the U.S., grain harvest.
Up to the present, the enterprise of China's production foodstuff drying device has reached family more than 500, in terms of mechanical growth pattern,
Although in 8 years of 2005-2013, the usage amount of foodstuff drying device risen to from 3.6 ten thousand 80,000 with
On, the usage amount of annual foodstuff drying device also increases substantially.But the grain heat-drying machinery in China is horizontal on the whole still locates
In the starting stage.2014, national grain machinery drying rate only accounted for the 10% of total output of grain, and the U.S., Japan are
Reach 95%.The grain drying machinery in China is at present also there are many problems, such as the degree of automation is not high, and the energy is fossil
Fuel and energy consumption is big, has a significant impact to the quality of grain after baking, therefore at the problems such as being easy to cause stifled grain or uneven drying
It is badly in need of the higher grain heat-drying machinery of the degree of automation.
Although being made some progress in recent years to the research of foodstuff drying device control system, mainly still pass through hand
The moisture content of dynamic control foodstuff drying device, is also difficult to reach supermatic degree, cause China have every year a large amount of grains because
Moisture content after drying is too high to cause massive losses.And the nonlinear system that grain heat-drying process is a large dead time, interferes more
System, the national standard for being difficult to reach grain security storage using manual control.Grain moisture content number directly affect its storage,
Loss amount and quality in process refer to so grain moisture content is all at home and abroad the quality that grain processing department focuses on to control
Mark.During the control of grain heat-drying to baking after the detection of grain moisture content be highly important, therefore make on sound lines
It is essential that grain moisture content after baking, which is detected, with living standard step up and industry rapid hair
Exhibition, makes grain measurement of moisture content instrument have good market prospects.At present, foodstuff drying device uses extensive in grain processing field, main
If the grain for needing to process or store is dried, prevent from going mouldy and influencing the quality of grain.But existing grain heat-drying
Machine only has drying structure mostly, and without dedusting structure, humidity is lower after grain heat-drying, it is easy to dust be caused to be existed everywhere, influenced
Grain appearance and air quality.
Invention content
Present invention mainly solves the technical issues of：Low for existing drying technology drying efficiency, internal dust is not easy
The problem of removing, the present invention provides a kind of grain heat-drying dust-extraction units.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
A kind of grain heat-drying dust-extraction unit, is provided with conveyer belt including loading hopper, below the loading hopper, on conveyer belt
Side and right side are provided with heating unit, and inner walls are additionally provided with temperature sensor, and motor, housing right side are provided with below housing
Dedusting fan is provided with, filter screen is provided between dedusting fan and housing, housing bottom is provided with humidity sensor, and humidity passes
It is discharge port on the right side of sensor, housing is supported by stent.
A kind of application process of grain drying device is：The grain of required drying is poured into from loading hopper, grain pass through into
Funnel enters conveyer belt, and the grain on conveyer belt is dried, passed through by the heating unit work on conveyer belt top and right side
The temperature sensor detection enclosure interior temperature of inner walls, the communicated band of grain are removed after falling by dedusting fan effect
Dirt places grain by filter screen and enters dedusting fan, and after grain falls into housing bottom, it is wet to detect grain by humidity sensor
Whether degree is up to standard, then discharges the grain after drying through discharge port.
The dedusting fan is by the effect of wind turbine by the dust adsorption in grain.
Ventilation hole is provided on the dedusting fan.
The housing is L-shaped, and the communicated band transmission of grain continues to dry and be dusted after falling.
The beneficial effects of the invention are as follows：
（1）Due to needing the coal-fired grain for generating hot wind and removing drying belt moisture during grain heat-drying, in grain drying tower
Use during will inevitably generate air pollutants, so grain drying tower, before flue gas is discharged, desulfurization takes off
Nitre dedusting becomes an essential link.But people not yet carry out deeply grain drying tower desulphurization denitration dust-extraction unit
The research entered, a large amount of smoke pollution environment can be discharged by generating thermal energy by burning coal to dry grain, and the present invention uses
Heat source of the electric heating device as drying grain, electric heating device is more environmentally friendly compared with burning coal, and thermal energy
Utilization rate higher, be conducive to improve grain heat-drying efficiency and thermal energy utilization rate.
（2）Secondary pollution easily occurs for the dust-extraction unit in existing grain drying device, it is difficult to minute dusts particle is removed,
Dust blockage problem is serious, the present invention using dedusting fan as dust-extraction unit, by the rotation of wind turbine by grain dropping process
Dust inside middle casing is adsorbed, and being dusted in grain dropping process can inhale the dust on grain surface completely
Attached, compared to the dedusting in grain transmission process of traditional dedusting method, grain is packed together, and internal dust is not easy away,
The dust removing effects of the present invention are more preferable.
