Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is specifically described.
In the embodiment of the present invention, the hot air type heating Domestic oil press with two air ports is described, but it should be noted that it is not limit the inlet number in the present invention, and just in order to those skilled in the art can understand the embodiment of the present invention better.Air port in the present invention can have multiple, becomes convection current, heat the oil plant in oil plant case between multiple air port with the oil plant box-shaped of oil press.
Embodiment 1:
Hot air type heating Domestic oil press as a kind of in Fig. 1, Fig. 3, comprises the air heater 3 providing hot blast in oil plant case 1, oil supply hopper 1;
The wall box of described oil plant case 1 is provided with the first air port 4 near bottom;
The wall box of described oil plant case is also provided with the second air port 10, and described second air port 10 and described first air port 4 be not in same level position;
Described air heater 3 comprises hollow pipeline, is located at the heating 6 heated hollow pipeline air wherein in hollow pipeline;
Preferably, as a kind of embodiment, described heating 6 is resistance wire or PTC heater;
Described hollow pipeline comprise dock with described first air port 4 first export 41, and to dock with described second air port 10 second exports 101, described first air port 4 and first exports 41 and to be docked and connected the defeated air port of formation first, and described second air port 101 and second exports 101 and to be docked and connected the defeated air port of formation second;
Described air heater 3 also comprises the blower mechanism be arranged in described hollow pipeline; Described blower mechanism makes the air in the hot gas in described hollow pipeline and described oil plant case form different directions circulative convection by described first defeated air port and described second defeated air port and carries hot gas to described oil plant case.
In a cyclic process, after air heater 3 is by the air heat in hollow pipeline, hot gas in hollow pipeline is exported hot gas by the first defeated air port to oil plant case by blower mechanism, the heat accepted than the oil plant away from the first air port 4 the closer to the oil plant in the first air port 4 is many, and now the second defeated air port is inlet scoop, suck back from oil plant case in air to hollow pipeline and heat, form convection current and circulating-heating is carried out to the oil plant in oil plant case;
In another cyclic process, when blower mechanism alternation, after changing blowing direction, at blower mechanism, the hot gas in hollow pipeline is exported hot gas by the second defeated air port to oil plant case, the heat that the oil plant the closer to the second defeated air port accepts than the oil plant away from the second defeated air port is many; And now the second defeated air port is inlet scoop, sucks back from oil plant case in air to hollow pipeline and heat, form convection current and circulating-heating is carried out to the oil plant in oil plant case;
And then carry out next one circulation, so repeatedly.
Hot air type heating Domestic oil press in the embodiment of the present invention, in different cyclic processes, by the hot blast that blower mechanism is the oil plant conveying formation convection current in oil plant case from different directions, the oil plant being conducive to the oil plant case being arranged in diverse location is heated evenly, avoid being in the overheated or inequality of being heated for a long time of the oil plant of diverse location in hopper, hot blast from different air ports out, can angle heat oil plant from different directions, is conducive to heating oil plant equably.
Preferably, as a kind of embodiment, described blower mechanism comprises control circuit, and controls the first blower fan 7 and the second blower fan 8 of alternation by control circuit; The wind direction that second blower fan 8 produces is contrary with the wind direction that the first blower fan 7 produces, and the first blower fan 7, second blower fan 8 couples with control circuit respectively.
Preferably, as a kind of embodiment, described control circuit comprises controller, D/A converting circuit, and drive the respective drive circuit of the first blower fan, the second blower fan, first blower fan, the second blower fan couple with corresponding drive circuit respectively, and described drive circuit is coupled by corresponding D/A converting circuit and controller.
Described first blower fan 7, second blower fan 8 is all arranged in the hollow pipeline of described air heater 3.
Preferably, as a kind of embodiment, described first air port 10, air port 4, second is respectively equipped with the first airstrainer 5, second airstrainer 11; The present invention is by being arranged on the airstrainer in air port, preferably, as a kind of embodiment, mesh (hole) diameter of described airstrainer is at below 1mm, can prevent impurity from entering air heater from oil plant case, thus improve the security of heater, the generation of security incident can be avoided.The alternation of blower mechanism different directions, hot blast alternately from different air port out, change with making wind direction alternate cycles, wind direction can be avoided constantly to apply active force to impurity towards the flowing of single direction for a long time, and help impurity tightly to adhere on screen pack, the impurity be just stained with on the screen pack of air port can be blown open, impurity is prevented to be stained with on screen pack, screen pack is avoided to block, make the hot blast smooth and easy blowout of energy and circulation, keep circulation unimpeded, carry out being beneficial to the load reducing blower fan, can energy-conserving and environment-protective.
Hot air type of the present invention heating Domestic oil press, the first air port, second air port of oil plant case can become hot-wind inlet, under the first blower fan, the second blower fan alternately work, hot blast alternately from the first air port, the second air port out.When the first air port blowout hot blast, the second air port is inlet scoop, when the second air port blowout hot blast, first air port is inlet scoop, and hot blast blows to oil plant in different air port, enters the gap between oil plant, oil surface is heated, then shunting enters next oil plant gap, continue heating; Or, directly clash into oil surface, after reflection, enter the gap of oil plant again, direction can be changed by multiple reflections, homogeneous heating can be carried out to the surface of all directions of oil plant, and make oil plant fully and thermo-contact, the thermal efficiency can be improve.When the first air port blowout hot blast, second air port is inlet scoop, now, the heat that the oil plant the closer to the first air port accepts than the oil plant away from the first air port is many, when after blower fan alternation, when the second air port blowout hot blast, first air port is inlet scoop, and the heat that the oil plant the closer to the first air port accepts than the oil plant away from the first air port is few, after blower fan alternation, the favourable oil plant being positioned at diverse location is heated evenly, avoid being in the oil plant of diverse location in hopper overheated or for a long time stressed less than; Hot blast from different air ports out, can angle heat oil plant from different directions, also can be conducive to heating oil plant equably.
