Abstract
The invention relates to an air duct device having an adjusting display device. A discharge pipe is arranged on a shell; the lower part of the discharge pipe is in cup joint with an adjusting plate; an annular air duct is defined by the adjusting plate and the shell; a frame body is arranged at one side of the shell; multiple hanging hooks are arranged on the frame body from top to bottom; the top of the adjusting plate is connected with one end of a lower connecting rod; the other end of the lower connecting rod is connected with one end of an upper connecting rod; the other end of the upper connecting rod is clamped into the hanging hooks after penetrating through the shell; and a wind speed sensor and a wind volume sensor are arranged in the shell, and are connected with a display screen. The air duct device has the advantages that the air duct section can be changed and further the air speed and the air volume can be adjusted, so that the wind speed and the wind volume can be adjusted according to the practical material flows and material batches; the device is flexible to use and the actual impurity removal rate is largely improved; the air duct device has the advantages of simple structure, wide application, level type control and convenience for use; and the wind speed and the wind volume in the shell can be detected at any time by the wind speed sensor and the wind volume sensor, and are output through the display screen.
Description
Technical field
The present invention relates to a kind of air-duct apparatus with adjusting display device.
Background technology
It is fixing for removing gently assorted, little assorted winnowing machine air channel for cereal at present, and wind speed and air quantity are all determined, during reality uses, when inlet amount changes, impurities removing efficiency is floating larger.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of air-duct apparatus with adjusting display device, can according to actual conditions by changing the long-pending size adjustment wind speed of duct cross-section and air quantity, dust removal rate is high, and easy to adjust, wind speed in housing and air quantity can be understood at any time by display screen.
Air-duct apparatus with adjusting display device of the present invention, comprise housing, tremie pipe, tremie pipe is arranged on housing, tremie pipe bottom is socketed with adjustable plate, adjustable plate and housing form annular passage, the side of housing is provided with support body, support body is provided with multiple hook from top to bottom, adjustable plate top is connected with one end of lower link, the other end of lower link is connected with one end of upper connecting rod, the other end of upper connecting rod is stuck in hook through after housing, the downward-sloping setting of lower link, upper connecting rod is inclined upwardly setting, air velocity transducer and air flow sensor is provided with in housing, air velocity transducer is connected with display screen with air flow sensor.
Described adjustable plate is the round platform that a tilting section is formed around axle.
Described housing is upwards intilted truncated cone-shaped along bottom, and housing and adjustable plate lower end form the smallest cross-sectional of annular passage between the two.
Described support body is provided with 5-10 hook.Hook number is more, and adjustable more grades.
Described lower link and upper connecting rod are hinged.
Described upper connecting rod is provided with elastic sealing element through the position of housing.Prevent material from spilling from junction.
Described air velocity transducer and air flow sensor are positioned in the inner walls of adjustable plate top position.
Described display screen is arranged on support body.
Operation principle is:
For air draught or blowing-type winnowing machine, wind moves upward from housing bottom, when needs improve wind speed, rotate counterclockwise connecting rod, drive adjustable plate upward sliding by lower link, the annular passage minimum sectional area that adjustable plate and housing are formed diminishes, and can be known by the relation of wind speed and sectional area, when the sectional area that wind passes through diminishes, wind speed improves, and when sectional area becomes large, wind speed reduces, when needs reduce wind speed, rotate clockwise connecting rod.Be stuck in the hook internal fixtion of correspondence position on support body after upper link rotatable completes, air velocity transducer and air flow sensor can detect wind speed in housing and air quantity at any time, and are exported by display screen.
The beneficial effect that the present invention has is: the air-duct apparatus with adjusting display device passes through change duct cross-section and then regulate wind speed and air quantity, the adjustment of air quantity, wind speed can be carried out according to the difference of actual mass flow and material batch, use flexibly, substantially increase actual impurities removing efficiency; Structure is simple, can be used for various forms of winnowing machine, as air draught type or blowing-type winnowing machine, widely applicable; Lever controls, easy to use; Air velocity transducer and air flow sensor can detect wind speed in housing and air quantity at any time, and are exported by display screen.
