Description
Technical field
The utility model relates to the technical field of compound fertilizer producing equipment, is specifically related to a kind of composite heat transfer rotary drum drying machine.
Background technology
Composite heat transfer rotary drum drying machine is mainly used in composite fertilizer drying, also be widely used in the oven dry of building materials, metallurgy, chemical industry, cement, slag, pulverized limestone, coal dust, clay etc., the main body of composite heat transfer 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.Composite heat transfer rotary drum drying machine is still widely used in the fields such as metallurgy, building materials, chemical industry at present.
Existing composite heat transfer rotary drum drying machine is if any following shortcoming: in composite heat transfer tumble drying machine drum body, material is shed after repeatedly being taken up by lifting blade, thus when carrying out heat exchange with hot-air, material is large to the impact of cylindrical shell, the shortcomings such as barrel wear is very fast.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of good drying effect, buffering material, and the composite heat transfer rotary drum drying machine of protection drier body.
In order to solve the problems of the technologies described above, the utility model provides a kind of composite heat transfer rotary drum drying machine, comprise drier body, charge door and discharging opening, at the inwall of described drier body, flow-guiding channel is set, described flow-guiding channel is connected with hot air duct, and described flow-guiding channel inner circumferential circle wall is communicated with water conservancy diversion arm, and described water conservancy diversion arm is L-shaped, described flow-guiding channel surface is provided with one deck protection network, and described water conservancy diversion arm is through in protection network.
The composite heat transfer rotary drum drying machine tool of technique scheme is adopted to have the following advantages: hot blast sends into flow-guiding channel by hot air duct, hot blast in flow-guiding channel has the effect of preliminary preheating to rotary drum drying machine, simultaneously, hot blast is blown in drying cylinder body through water conservancy diversion arm, wet stock is dried, the water conservancy diversion arm of L shape also has certain agitaion to wet stock, makes the good drying effect of rotary drum drying machine; And protection network and water conservancy diversion arm form protection in dryer, prevent material from directly striking cylinder inboard wall, cause larger impulsive force to rotary drum drying machine, thus make drier body not fragile.
Preferably, conveniently hot gas carries out abundant drying functions to material, and the diameter of described water conservancy diversion arm is set to 1/3rd of hot air duct diameter.
Preferably, conveniently that protection network and flow-guiding channel is firm, described protection network and flow-guiding channel inwall are welded and fixed by connecting plate.
Preferably, conveniently water conservancy diversion arm and flow-guiding channel are fastenedly connected, described water conservancy diversion arm and flow-guiding channel are welded and fixed.
Accompanying drawing explanation
Fig. 1 is the structural representation of composite heat transfer rotary drum drying machine.
In figure: 1-drier body, 2-hot air duct, 3-flow-guiding channel, 4-protection network, 5-water conservancy diversion arm.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As shown in Figure 1: the utility model provides a kind of composite heat transfer rotary drum drying machine, comprise the drier body 1 be obliquely installed, charge door and discharging opening, drier body 1 is provided with the pivotal running part of drier body 1, at the inwall of described drier body 1, flow-guiding channel 3 is set, flow-guiding channel 3 is connected with hot air duct 2, described flow-guiding channel 3 inner circumferential circle wall is communicated with water conservancy diversion arm 5, described water conservancy diversion arm 5 is L-shaped, described flow-guiding channel 3 surface is provided with one deck protection network 4, described water conservancy diversion arm 5 is through in protection network 4, the diameter of described water conservancy diversion arm 5 is set to 1/3rd of hot air duct 2 diameter, described protection network 4 is welded and fixed by connecting plate with flow-guiding channel 3 inwall, described water conservancy diversion arm 2 is welded and fixed with flow-guiding channel 3.
When using, wet stock adds from the higher one end of drier body 1, and through the inside of drier body 1, protection network 4 effectively contacts with wet stock with water conservancy diversion arm 5, and dried product is from lower one end collective low.In dry run, material, by means of the slow rotation of drier body 1, moves from higher one end to lower one end under gravity.Hot blast sends into flow-guiding channel 3 by hot air duct 2, hot blast in flow-guiding channel 3 has the effect of preliminary preheating to tumble drying machine drum body 1, simultaneously, hot blast is blown in drying cylinder body 1 through water conservancy diversion arm 5, wet stock is dried, water conservancy diversion arm 5 pairs of wet stocks of L shape also have certain agitaion, make the good drying effect of rotary drum drying machine; And protection network 4 and water conservancy diversion arm 5 form protection in dryer, prevent material from directly striking drier body 1 inwall, larger impulsive force is caused to rotary drum drying machine, thus make drier body not fragile.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model principle; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
