Description

Rotary drum drying machine
Technical field
The present invention relates to a kind of compound fertilizer producing equipment, particularly a kind of drying effect is good, and has the rotary drum drying machine of energy-saving effect concurrently.
Background technology
The main body of rotary drum drying machine slightly tilts and the pivotal cylinder of energy.The operation principle of this device is as follows: wet stock adds from the top of the higher one end of cylinder, and through cylinder interior, effectively to contact and dried with by the hot blast in cylinder or heating wall, dried product is from lower one end collective low.
In dry run, material, by means of the slow rotation of cylinder, moves from higher one end to lower one end under gravity.Usually, cylinder inboard wall is equipped with forward flight, it is constantly taken up material and spills down, and the thermo-contact surface of material is increased, to improve rate of drying and to impel material to move forward.Heat carrier used in dry run is generally hot-air, flue gas etc.If heat carrier directly contacts with material, then after dryer, usually with cyclone dust collectors, the fine carried under one's arms in gas is trapped, off-air then emptying after cyclone dust collectors.Rotary drum drying machine is still widely used in the fields such as metallurgy, building materials, chemical industry at present.
Existing rotary drum drying machine is if any following shortcoming: 1) hot-air generally enters inner barrel from the higher one end of cylinder, discharged through cyclone separator by lower one end, its shortcoming be originally at the dried material of cylinder discharge end from the saturated vapor newly absorbing discharge end, drying effect reduces; 2) gas of discharging through cyclone separator still has higher temperature, wastes energy; 3) the hot-air wind speed of hot-blast stove conveying can not make size adjustment according to oven dry situation, causes energy consumption to increase.
For above-mentioned deficiency, applicant has invented a kind of rotary drum drying machine, to solve the problem.
Summary of the invention
In view of this, the invention provides rotary drum drying machine a kind of, the intake method of this rotary drum drying machine to hot-air has made change, and then enhances drying effect, and reduces energy consumption, solves the problem that existing rotary drum drying machine drying effect is poor, energy consumption is high.
The present invention is solved the problem by following technological means:
Rotary drum drying machine of the present invention, comprise be obliquely installed cylindrical shape body, supporting whole body can pivotal bracket portion and drive body pivotal running part, one end of described body has charge door, the other end is provided with discharging opening, also comprise the hot-blast stove for carrying hot-air in body, described hot-blast stove is connected with the inside of body by ajutage, and described hot-blast stove adopts and the frequency conversion fan of controlled wind speed can carry out hot-air conveying.
Further, described ajutage extend into internal body by the comparatively low side of body.
Further, described ajutage extend into the position of internal body near stage casing by body compared with low side.
Further, be positioned at the ajutage of internal body, its cross section is triangle.
Further, the two ends of described body are respectively provided with a set of cyclone dust collectors.
Further, described body inwall is provided with flight.
Beneficial effect of the present invention: rotary drum drying machine of the present invention, comprise be obliquely installed cylindrical shape body, supporting whole body can pivotal bracket portion and drive body pivotal running part, one end of described body has charge door, the other end is provided with discharging opening, also comprise the hot-blast stove for carrying hot-air in body, described hot-blast stove is connected with the inside of body by ajutage, and described hot-blast stove adopts and the frequency conversion fan of controlled wind speed can carry out hot-air conveying.Adopt frequency conversion fan can regulate the size of wind speed according to oven dry situation, little wind speed can be adopted as during body preheating, when humidity is larger, large wind speed can be adopted, to reduce energy consumption.In addition, rotary drum drying machine of the present invention has also made adjustment to mode of heating, make hot-air can be sent to internal body by near body compared with the middle and lower part of low side, saturated vapours is discharged respectively by the two ends of body, and then not only reduce that simple be vented the wind speed caused from side large, the problem that dust is high, and material that body end is dried be there will not be return wet problem.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of rotary drum drying machine of the present invention;
Fig. 2 is cross-sectional view shown in A-A in Fig. 1.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as illustrated in fig. 1 and 2: the rotary drum drying machine of the present embodiment, comprise slightly be obliquely installed with horizontal plane cylindrical shape body 1, supporting whole body can pivotal bracket portion 2 and drive the pivotal running part 3 of body 1, the structure of described bracket portion 2 and running part 3 can adopt prior art, one end of described body 1 has charge door 11, the other end is provided with discharging opening 12, and described body 1 inwall is provided with flight 6; Also comprise the hot-blast stove 4 for carrying hot-air in body 1, described hot-blast stove 4 is connected by the inside of ajutage 41 with body 1, and it is inner that described ajutage 41 extend into body 1 by the comparatively low side of body 1; Described hot-blast stove 4 adopts and the frequency conversion fan 42 of controlled wind speed can carry out hot-air conveying.Adopt frequency conversion fan to make rotary drum drying machine of the present invention can regulate the size of wind speed according to oven dry situation, little wind speed can be adopted as during body preheating, large wind speed can be adopted when humidity is larger, and then reduce energy consumption.
As the further improvement of technique scheme, described ajutage 41 is by the position extending into the inner close stage casing of body 1 compared with low side of body 1, internal body can be sent to by near body compared with the middle and lower part of low side to make hot-air, saturated vapours is discharged respectively by the two ends of body, and then not only reduce that simple be vented the wind speed caused from side large, the problem that dust is high, and material that body end is dried be there will not be return wet problem.
As the further improvement of technique scheme, be positioned at the ajutage 41 of body 1 inside, its cross section is triangle.Because ajutage 41 itself has very high temperature, also can play the effect of oven dry when ajutage 41 contacts with material, in addition, stop the top dropping on ajutage 41 for avoiding material, the cross section of ajutage 41 can be set to triangle.
As the further improvement of technique scheme, the two ends of described body 1 are respectively provided with a set of cyclone dust collectors 5.Preferably, the air outlet of described two cyclone dust collectors 5 is interconnected, and described frequency conversion fan 42 is arranged on the air outlet place of two cyclone dust collectors 5, and above-mentioned setting simplifies the structure of equipment.Because the hot-air with dust is discharged from the two ends of body 1 respectively, so need respectively to arrange a set of cyclone dust collectors 5 in the both sides of body, to filter the air containing dust.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
