Abstract
The invention relates to a self-cleaning screw conveyor. A spiral shaft I and a spiral shaft II are installed inside a cabinet body; the spiral shaft I and the spiral shaft II have the same size and screw pitch and opposite spiral directions, are arranged in parallel, and are axially staggered by half a screw pitch; the radial space between the spiral shaft I and the spiral shaft II is larger than the diameter of the spiral shaft I and the spiral shaft II; and the torque input ends of the spiral shaft I and the spiral shaft II are connected with two low speed shafts of a speed reducer respectively, so that the spiral shaft I and the spiral shaft II have the same rotating speed and opposite rotating directions. The self-cleaning screw conveyor adopts a structure with the double spiral shafts which have the same rotating speed and the opposite rotating directions and are driven by the same speed reducer, the two spiral shafts do not interfere in each other but can clean each other; and a sealing cover is added on the cabinet body of a feeder, and an air inlet, an air outlet and a material inlet are formed in the sealing cover, so that the self-cleaning screw conveyor can be applied to places which are required to be sealed in the conveying process by matching with other components of a conveying system, and is particularly applicable to places where high temperature gas and materials are required to exchange heat in feeders.
Description
Technical field
The present invention relates to a kind of material conveyer tool, especially a kind of mechanical moving device with self-cleaning function.
Background technology
Material conveying device is of wide application, such as the transmission of coal in the thermal power plant, and the transmission of raw material in the food processing factory.Some material has certain viscosity, and easy and transmission shaft takes place gluing, even occurs stopping up, and influences equipment operation.Such as the material that has certain humidity in the living beings compression process easily and transmission shaft gluing; The mud of certain humidity range also has very big viscosity in the sludge incineration factory, often mud is carried out preheating in the sludge incineration process, and initial moisture percentage in sewage sludge is greater than 60%; Good fluidity, but nonflammable, so need carry out preheating to it; Water ratio is in the plastic stage at 35 ~ 60% mud; The flowing power variation, viscosity increases, and is easy to transmission shaft gluing.
Summary of the invention
The present invention will provide a kind of self-cleaning screw conveyor, and this installs diaxon mutually noninterfere, has the effect of mutual cleaning; And can install seal closure additional, can be used for material and transmit the field, install seal closure additional after, being particularly suitable for transport process needs the leak free occasion.
For realizing above-mentioned purpose, technical scheme of the present invention is: a kind of self-cleaning screw conveyor comprises seal closure, the screw shaft I; The screw shaft II, retarder, electrical motor, casing; Be characterized in: screw shaft I and screw shaft II are housed in the casing, and the screw shaft I is identical with pitch with screw shaft II size, rotary orientation is opposite; Be arranged side by side, the half pitch that axially staggers, radial spacing is greater than its diameter; The torque input end of screw shaft I and screw shaft II is connected with two slow-speed shafts with one speed reducer respectively, makes the screw shaft I identical with screw shaft II rotating speed, switched in opposite.
Install seal closure on the casing additional, seal closure is provided with induction opening, air gate and material inlet, and casing is provided with material outlet.
Install an asessory shaft that plays the role of changing additional between slow-speed shaft in the retarder and the high speed shaft.
The invention has the beneficial effects as follows:
The present invention is employed in the double helix axle construction of the identical switched in opposite of rotating speed that drives with one speed reducer, and two double helix axle mutually noninterferes have the effect of mutual cleaning.Next is on the casing of feeder, to have installed seal closure additional; Induction opening, air gate and material inlet are arranged on the seal closure; Cooperate with other parts of transfer system to can be used for transport process and need the leak free occasion, needing to be particularly suitable for high-temperature gas and material in feeder, to carry out the occasion of interchange of heat.
Description of drawings
Fig. 1 is a structural upright scheme drawing of the present invention;
Fig. 2 is double helix axle of the present invention and casing connecting bridge structural upright scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1, self-cleaning screw conveyor of the present invention, by seal closure 1, screw shaft I 2, screw shaft II 3, retarder 4, electrical motor 5, casing 6 compositions such as grade.Induction opening a is arranged on the seal closure 1, air gate b, material inlet c has material outlet d on the casing 1; Screw shaft I 2 is identical with screw shaft II 3 sizes, and hand of spiral is just in time opposite, and pitch is identical, and diaxon is arranged side by side, the half pitch that axially staggers, and radial spacing is a bit larger tham its diameter.Diaxon rotates with same rotational speed in opposite directions during work, mutually noninterfere on the space, but can mutually the material in another be cleared, prevent that material and transmission shaft are gluing.Two screw shafts have two slow-speed shafts with one speed reducer 4 to drive respectively, can guarantee that speed of screw shaft is identical, switched in opposite.Retarder 4 has wherein installed an asessory shaft that plays the role of changing additional between slow-speed shaft and the high speed shaft.
The high speed shaft rotation of electrical motor 5 driven gear retarders 4, retarder 4 inside have 4 gears to be arranged side by side, and wherein 1 miniature gears links to each other with high speed shaft; Other three is the identical gear of the number of teeth; Big gear wheel wherein plays switching-over and transfer function, and the big gear wheel of both sides has identical rotating speed, but switched in opposite; Link to each other with two slow-speed shafts respectively, drive screw shaft I 2 and rotate with screw shaft II 3.Seal closure 1 is housed above the casing 6, induction opening a is arranged on the seal closure, air gate b, material inlet c, induction opening and air gate position can be changed mutually, and material outlet d is arranged on the casing.Material gets into feeder from import c during work, under the drive of screw shaft, advances, and gas flows into from induction opening a simultaneously, with mixing of materials and carry out interchange of heat, flows out from air gate b afterwards, and last material spreads out of from outlet d.Two screw shafts have the effect of mutual cleaning, and whole material transport process is continuously carried out, and have guaranteed production efficiency; And can in feeder, accomplish mixing and hot-swap feature of material and gas.
