5.The screw auger cooperation, which rises expects pipe 2, will be located at the top of the material lifting to dry cavity of dry cavity bottom.
The middle and lower sections of described liter of expects pipe 2 are circular cylindrical pipe, and upper section is formed by connecting by multistage pipeline of different shapes, including
Gradually reducing pipeline 8, straight round tube 9 and round table-like pipeline 10, the broadside diameter of the gradually reducing pipeline 8 and the diameter of the circular cylindrical pipe
Identical, the broadside of gradually reducing pipeline 8 is fixedly connected with one end of the circular cylindrical pipe, the narrow side diameter of the gradually reducing pipeline 8 with
The diameter of the straight round tube 9 is identical, and the narrow side of gradually reducing pipeline 8 is fixedly connected with one end of the straight round tube 9, the straight round tube 9
The other end be fixedly connected the round table-like pipeline 10 bottom surface and connection described in round table-like pipeline 10.
The top surface of the round table-like pipeline 10 is fixedly connected and one end of one discharge nozzle 12 of connection, the discharge nozzle 12 are arranged
Inside the feed pipe 11, another end surfaces of the discharge nozzle 12 are equipped with connector, such as connection screw thread 22, and stretch out
To outside feed pipe 11, a hose can be connected by connection screw thread to facilitate collection dry material.
The junction of the discharge nozzle 12 and round table-like pipeline 10 is equipped with separated material valve 13, the inner wall of round table-like pipeline 10
Face is equipped with material mass dryness fraction inductor 14, the number of the material mass dryness fraction inductor 14 can according to the actual situation depending on, in figure only
Show one, but can actually be it is multiple, such as 2 or more, more accurately to detect material drying regime.
The bottom surface of the round table-like pipeline 10, which has been evenly arranged, spills material hole 15, and the aperture for spilling material hole 15 is greater than particulate matter
The partial size of material, corresponding each spill are provided with linkage valve on material hole 15.
The separated material valve 13, material mass dryness fraction inductor 14 and linkage valve are all electrically connected with control system.Its interval
The open and-shut mode of valve 13 and linkage valve is expected on the contrary, being the separated material valve closure, when linkage valve closes when linkage valve is opened
When conjunction, separated material valve is opened.The specific opening and closing of valve passes through the dry materials situation at 14 sense channel of material mass dryness fraction inductor,
And will test value in real time and feed back to control system, when detected value meets the predetermined range of dry materials requirement setting, control
System issues instruction, opens separated material valve, closes linkage valve；When detected value does not meet the predetermined value of dry materials requirement setting
When range, control system issues instruction, opens linkage valve, closes separated material valve.
The two sides of 6 upper surface of pedestal are mounted on cylinder 16, a telescopic rod 17 are connected on the cylinder 16, described in two
A connecting plate 18 is installed at the top of telescopic rod 17, and two connecting plates 18 are fixedly connected with (such as being bolted) described dry
The bottom both ends of dry cabinet 1.Under the action of cylinder 16 and telescopic rod 17, the left and right ends of drying box 1 can be certain
It is swung up and down in amplitude, promotes material mobile to dry cavity center, be conducive to material and enter in liter expects pipe 2.
The granulated material drier further includes for heat source needed for dried material, which can be set described
Inside drying box 1, internal heat resource is constituted, also can be set outside the drying box 1, constitute external heat source, heating is dry
Dry mode can be using diversified forms, preferably heated-air drying such as electric heating, microwave heating, heat-conducting oil heating, Hot-blast Heatings.
In order to monitor heating state in drying chamber body, temperature sensor 21 is also equipped with inside the drying box 1.
The working method of granulated material drier provided by the present embodiment is as follows: as shown in Figure 1, particulate matter to be dried
Material enters dry inside cavity from feed pipe 11, falls on the outer surface of round table-like pipeline 10 and then disperses to fall on dry cavity bottom
Portion, material and hot wind come into full contact with drying during the falling process, and screw auger cooperation, which rises expects pipe 2, will be located at dry cavity bottom
Material lifting to dry cavity at the top of, dropped back into again from the bottom surface hole Sa Liao 15 of the round table-like pipeline 10 of the upper section of liter expects pipe 2 dry
Dry cavity bottom is dried again.When material mass dryness fraction inductor 14 detects that dry materials situation meets dry materials and wants
When asking, by control system issue instruct, open separated material valve, close linkage valve, material no longer from spill material hole 15 drop back into drying
Cavity bottom, but continued up under the action of screw auger, increase since upward material constantly accumulates, close to out
The material of expects pipe 12 moves up under the extruding of screw auger and back material to be discharged by discharge nozzle 12, is received in time by hose
The dried material of Ji Chuliaoguanchu.
Phase after the drying depends merely on the upward active force of screw auger and lacks bottom since material is reduced in drying chamber body
The extruding force of the material constantly moved upwards, it is difficult to continue to be discharged from discharge nozzle 12 by dried material.It therefore, can be from lower section
It makes adjustment in face.
On the one hand, telescopic screw auger can be selected, the length of the output shaft of the helical axis 4 or rotating electric machine 7
Degree is adjustable flexible, can extend screw auger protrude into discharge nozzle 12 when needed.It on the other hand, can also be in drying box
