Therefore patent documentation WO96/38721 has introduced a kind of scheme, wherein microwave remote sensor is designed to three printed lines (tri-plate line), measurement is full of the line characteristic of the sensor region of loose unpacked material, wherein said sensor region is the part of measuring route, in described measuring route, except measuring temperature, also determine to have the density of the loose unpacked material of different humidity.Can control the humidity of loose unpacked material subsequently.Measure path is designed to the band scale part of separating with described loose unpacked material primary path according to weighing technology branch road.
European patent EP-A-34459 has introduced a kind of equipment that adopts batch processing mode to measure cereal humidity, wherein, a certain amount of material use vibrating channel is transported in the measuring vessel with capacitive transducer, determine humidity, utilize the gate on the bottom surface then, the loose unpacked material in the measuring vessel is discharged.
Germany Patent document DE-A-3532570 has introduced a kind of electric-capacity moisture metre, in handling capacity is measured, measuring vessel be designed to weigh container and Measurement of capacitor, wherein form three material paths that adjoin, the principal goods materials flow adopts delayed mode by measuring vessel, and two side branch roads are used to hold the material that overflows in addition.This measuring vessel has the outlet that can laterally close, and whole streams are imported a path of navigation, and the part streams mixes and tends to shock plate in path of navigation, utilizes the handling capacity meter to measure the horizontal force of shock plate.Germany Patent document DE-PS 2609167 has introduced a kind of equipment that utilizes the arm beam of steelyard to measure handling capacity with being fixed on the inclination measurement plate on the arm beam of steelyard, and it can not be subjected to the influence of product friction force and guarantee to measure exactly handling capacity.
Summary of the invention
The objective of the invention is to develop a kind of Humidity regulating equipment, specifically, a kind ofly can regulate the equipment of loose unpacked material humidity continuously, its simplicity of design can be determined the humidity as the loose unpacked material of the function of loose unpacked material density exactly.
In order to achieve the above object, the present invention proposes a kind of Humidity regulating equipment, be particularly useful for by microwave remote sensor perpendicular to the bulk material flow direction, and the humidity by the loose unpacked material in the measuring route of loose unpacked material is regulated continuously, wherein said measuring route is designed to three printed lines (tri-plate line), it is suspended on the weighing-appliance and is parallel with the major product path, be equipped with the measurement electronics in addition, it is characterized in that: in primary path, be provided with level sensor.
This compact equipment, simplicity of design, owing to be integrated system, so also can guarantee good sanitary condition.Weigh and moisture measurement between not free the delay.
This equipment comprises the device that is used for determining and adjusting initial humidity, also has a fluid flow regulator simultaneously, and a flow regulator that is positioned at the downstream.One the water device be set at the downstream of described flow regulator successively.
The present invention specifically is applied in the equipment of grinding wheat, and is used for measuring automatically, continuously and regulating for example humidity of cereal such as wheat, thereby effectively and equably pulverizes cereal.
Brief description
Hereinafter will at length introduce the present invention in conjunction with the accompanying drawings.
Fig. 1 has schematically shown Humidity regulating equipment;
Fig. 2 has shown the principle of work and power of humidity regulation.
Embodiment
Humidity regulating equipment comprises the housing 1 that has inlet 2, air-breathing opening 3 and discharge funnel 4.What begin to be positioned at inlet 2 downstreams is feed well 5, measuring route 6 and primary path 7 successively from entering the mouth 2.Bulk materials flow (cereal) is also homogenized by damping in conveying equipment.
Be provided with the microwave remote sensor 61 of patent documentation type that WO96/38721 introduces in the measuring route 6, next-door neighbour's measuring route 6 is provided with the discharge funnel, is provided with temperature sensor 62 in described discharge funnel.
One level sensor 71 is set in primary path 7, is used for regulating the material level of the bulk materials flow that patent documentation EP-B 1 introduced.Level sensor 71 has the hinge mounting rod, and this mounting rod is set up is transverse to or links to each other perpendicular to the flow direction of loose unpacked material and with a signal transducer.
Entire equipment is set on the track 30 between upper table 31 and the lower table 32.Control and display device 33 also are set on the track 30.Can adjust the height of worktable 31,32.
Measuring route 6 is suspended on the upper table 31 that is positioned at strainmeter 8 tops.
Utilization is positioned at the microwave remote sensor 61 of measuring route 6 and determines the humidity of cereal.In the temperature and weight of determining cereal, utilize known microwave moisture measurement technology determined transport properties in measuring route 6 to be used to determine the initial humidity of cereal.According to above-mentioned initial humidity, measured processing power and the final moisture content that is suitable for abrasive dust of regulation, in control device 33, determine the quantity of required wetting water (wetting water) continuously.Utilize the operation valve of water gaging device 50, the wetting water of accurately being measured after the quantity is transported in the machine 51 that catchments.Can set up the adjustment point value by using system controller 40.
Can select and adorn a Remote Control Indicator 41.
