I. Scope of application:
HGJ series chain slime dryer , widely used in food , feed , coal , metallurgy , cement and other factories in the drying process industry is a new type of material to dry heat exchange equipment , and with lower energy consumption Application scope is wide .
Soy : The raw material , watercress , soybean meal dry , add steam or warm water can be softened .
Cottonseed : The raw material , cake , cake drying precipitation by the addition of steam or hot water can be softened .
Corn Umbilical : dry precipitation .
Rice Valley : dry precipitation .
Coal sludge : dry precipitation .
Second , performance characteristics
The product is contact heat transfer , scraper chain of transmission , the use of heat transfer medium is saturated steam (or thermal oil ), has the following characteristics:
-
Simple installation and easy maintenance .
-
Low noise , broken rate , smooth and reliable performance.
-
High efficiency , low energy consumption .

5 , structure and working principle
HGJ series of drying machine consists of frame, into the hopper , heating parts, transmission parts and other components.
How it works: ( see Figure 1)
Material into the hopper into the heating film (1 ) on the movement as the scraper chain , followed through (1 ), ( 2 ), ( 3), ( 4 ), (5 ), ( 6 ) Heating , materials By heating and drying , by a gate into the next process .
6 , debug
-
Preparatory work before driving :
-
Clean up debris . Check whether all parts intact, check the reducer , motor, the connectors out of the trachea , and out of tube is intact.
-
Check lubrication system. Into the grease , to ensure adequate lubrication . Check oil level inside the level of deceleration , less than 20 # when adding oil or gear oil .
-
Rotate the reducer driven scraper chain is running , adjust the scraper chain tensioner make chain moderately elastic , elastic chain in the middle of the chain to bring a high degree of hand 50-80 is appropriate .
-
Check motor wiring , the motor direction of rotation as needed .
-
To move the test . Check around the block plate , circular plate , etc. not to stop the chain scraper , heating film can not stop the chain scraper docking run .
-
No Load Operation . Check whether the smooth running , the chain gear is normal , with or without abnormal noise , if any exceptions to stop checking .
-
No-load normal running , slowly turn into steam (or into the oil) valve to steam ( or thermal oil ) slowly clear, the memory chip will heat water all out , check the steam (or thermal oil ) are seamless pipe Steam (or leakage ) phenomena , such as seamless gas ( or oil ) phenomenon should gradually back off a small gas (or oil return ) valve , but do not absolutely relevant , do not make the heating -chip storage as well, so that Heating plate temperature increased gradually to keep the temperature uniform heating film is appropriate .
-
Debugging 5-20 minutes after the load , the device is in normal circumstances , you can run a load . First roller hopper and tested to achieve the uniformity of the material , so that the material heated chip to keep embryos at about 60 mm , into the material, the material balance , not flash , not lack of material to meet the need for good .
7 , precautions
1 , normal production operations , to strengthen inspection to prevent the rod-shaped objects into the machine, damaged scraper chain .
-
Parking longer piece in the winter heating should be put in the water net , to prevent the heating plate and pipe nipped .
-
Dryer before the shutdown , should stop feeding , and other materials embryo scraper chain will shave from the heating chip , you can stop , parking will be expected to prevent embryonic bake coke .
-
At work , not allowed to exceed the specified working pressure , working pressure safety valve to be adjusted to allow work within the scope of work .
8 , to maintain
-
Heater must be regularly checked . At least one external inspection per year , at least two years to conduct a comprehensive inspection . When heated to a certain degree of corrosion film thickness should be promptly repaired or replaced.
-
Pressure gauge , safety valve should be regularly inspected, at least once a year .
-
Long-term need , should heat the water in the film side of net , all of the oil recovery .
-
Run-time exception occurs immediately stop processing the sound .
-
Mechanical maintenance at least once half a year .
-
Reducer special attention in the early work of cleaning oil . If oil is dirty , especially mixed with iron filings , oil change immediately . Reducer to work for the six months to once oil .
