Description
Technical field
The present invention relates to wheat processing equipment, relate to a kind of spiral wheat measurer that quantitatively delivers from godown and arrange in pairs or groups that is used for wheat processing process wheat specifically.Use this equipment can guarantee that wheat delivers from godown in predefined ratio and flow, and guarantee the accuracy of flow and the stability of whole production line work.
Background technology
Wheat measurer is an imperative equipment in the wheat processing process.Because wheat breed is various, mass discrepancy is very big, be difficult to produce steady quality, the controlled product of quality with the wheat of single variety, so each big-and-middle-sized flour mill all there is the wheat blending link.The wheat measurer that can accurately control flow is installed in outlet at each wheat bin, by wheat measurer the wheat of two or more different qualities is arranged in pairs or groups in the ratio of setting, and just can realize stablizing the purpose of raw material quality, control product quality and product variety.To the requirement of wheat measurer be flow accurately, control conveniently, reliability and durability, simple in structure.
The wheat measurer that uses both at home and abroad has two types at present: vane type wheat measurer and electronic type wheat measurer.The vane type wheat measurer belongs to the category that positive displacement is joined wheat, and it is to rely on the impeller that rotates to control the flow of material as proportioning device.Impeller is divided into a series of lattice chamber that varies in size vertically, by the flow plate change material from different lattice chambers by changing the flow of material.The advantage of vane type wheat measurer is simple in structure, solid durable, and shortcoming is that quantitative accuracy is low, impeller easily stops up and unimpeded difficulty, weight of equipment are big.The electronic type wheat measurer belongs to the category that gravity type is joined wheat, it is to rely on shock plate and sensor to respond to the impulsive force of free-falling material, be converted to data on flows by the center instrument again, regulate the aperture of feed gate then according to the deviation of flow, make the flow of material meet the given numerical value of instruction.The advantage of electronic type wheat measurer be flow control accuracy higher, easily realize that Long-distance Control, shortcoming are that structure is complicated, cost is high, endurance quality is not high.
Summary of the invention
Purpose of the present invention provides at existing weak point in the above-mentioned prior art just that a kind of quantitative accuracy is higher, frame for movement is simple, cost is low, long-lived spiral wheat measurer.
Purpose of the present invention can realize by following technique measures:
Spiral wheat measurer of the present invention comprises the casing of the horizontal round tube shape structure of laying, by being arranged on bearing block on the end cap of casing two ends to be installed in screw propulsion mechanism in the casing by actuator drives with casing coaxial line mode; Near being provided with the charging aperture that is connected with the wheat bin outlet above the casing of transmission device one end, below the casing other end, be provided with the discharging opening that is connected with follow-up conveying equipment; Two sections settings before and after described screw propulsion mechanism is divided into from charging aperture to discharging opening, leading portion is the feeding section, back segment be quantitatively section; Wherein: all greater than blade diameter, the pitch of quantitative section, the ratio of its diameter, pitch dimension is 1.05:1 for the blade diameter of feeding section, pitch.
Transmission device described in the present invention is made of variable-frequency motor, decelerator; The output shaft of decelerator adopts shaft coupling to be connected with the axle head of screw propulsion mechanism (conveyor screw), to guarantee the precision of transmission.
The blade diameter of the section of feeding described in the present invention, pitch are in order to make the feeding section to quantitative section capacity feed greater than the purpose of the blade diameter of quantitative section, pitch all, and can guarantee that material is advanced by blade with full state in quantitative section.Because quantitatively section is the key position of flow-control, by changing the rotating speed of screw propulsion mechanism (conveyor screw), can change quantitative section speed that advances material, reach the purpose that changes mass flow.
For realizing on the spot or functions such as long-range reception instruction, data demonstration and remote data output, control motor speed that control system of the present invention is controlled by microprocessor, adopts formations such as human-computer interaction terminal, frequency converter to realize.
During work, operating personnel's instruction is passed through on the spot or the input of long-range terminal, and through microprocessor processes, the indication frequency converter changes the frequency of motor power, makes motor change rotating speed, thereby changes spirochetal rotating speed, changes the flow of material.
Beneficial effect of the present invention is as follows:
(1) the present invention is the equipment of dynamo-electric combination, combines the advantage of existing two class wheat measurers, has higher quantitative accuracy, has higher durability, and can realize remote computer control.
The groundwork part is made up of screw propulsion mechanism (conveyor screw) and housing, so it is simple in structure, controls easily, can not occur blocking up, blocking phenomenon, functional reliability height in the operate as normal.
Therefore quantitative section and the casing length that cooperatively interacts of screw propulsion mechanism (conveyor screw) can design according to instructions for use during fabrication, have greatly made things convenient for the layout of process equipment, help reducing height at the bottom of the storehouse, improve the capacity in storehouse.
