Description
Technical field
The utility model relates to a kind of vane-type twin shaft that is used for the modified ammonium nitrate-fuel oil explosive production line and puddles coolconveyer.
Background technology
In the modified ammonium nitrate-fuel oil explosive continuous automatic production, adopt common worm conveyor, the cold mixed material of high-temperature material and initiate low temperature in transfer roller, not to have through overcooling and puddle just to enter into the low temperature compounding process at present mostly from the high temperature batch mixing to the mass transport the low temperature batch mixing.Because the time that material is puddled in the continuous automatic production process is shorter, does not finally reach good cooling mixing effect.The inhomogeneous meeting of mixing of materials directly has influence on every blast performance of product; Material temperature after low-temperature mixed is too high, not only is unfavorable for the powder charge of product, and product produce and storage process in very easily moisture absorption and caking phenomenon takes place.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, provide a kind of vane-type twin shaft that is used for the modified ammonium nitrate-fuel oil explosive production line to puddle coolconveyer, it makes material just can cool off and puddle in course of conveying in the modified ammonium nitrate-fuel oil explosive automatic production line, in material conveying process, just can improve the mixture homogeneity of material, and make material reach favorable cooling effect, thereby improve the storage and the blast performance of modified ammonium nitrate-fuel oil explosive.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of vane-type twin shaft that is used for the modified ammonium nitrate-fuel oil explosive production line to puddle coolconveyer, comprise hopper, described hopper top is provided with 3 opening for feeds, the hopper bottom is provided with 1 discharge port, 2 main shafts that are parallel to each other are installed in the hopper, a plurality of blades are installed on each main shaft, described blade is arranged according to spiral-line, a main shaft wherein is by electric motor process speed reduction unit, small belt pulley and big belt pulley driven rotary, another root main shaft is by a pair of gear driven rotation, two main shafts are provided with different rotating speeds, and the blade on two main shafts is set to different blade turning diameters and different blade revolving spiral lift angles, the cocurrent flow type structure of identical pitch.
Described hopper middle part is provided with the interlayer that leads to cold water with upper/lower positions, and described interlayer is respectively arranged with water inlet pipe and rising pipe.
Described hopper top is provided with a venting port, and described venting port is provided with the venting port plate.
Described hopper is provided with access hole.
The utility model adopts less lead angle by the rotating paddle of the main shaft installation different size of two spirals, and the different speed of mainshaft reaches in material conveying process and improves the purpose that material is puddled effect; Hopper is from being provided with the interlayer of logical cold water below the middle part, can the material that pass through in the hopper be cooled off, and the obstructed cold water of the hopper first half is lowered the temperature, can reduce the temperature difference of cell body, realized and to have avoided the formation of hopper inwall water of condensation again to material cooling cooling.Like this, material was cooled off before entering cold mixed operation in advance and mix, not only alleviated the burden of later process, improved production efficiency, and the blast performance of product and shelf characteric also improve greatly.

Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of vane-type twin shaft that is used for the modified ammonium nitrate-fuel oil explosive production line to puddle coolconveyer, comprise hopper 1, described hopper top is provided with 3 opening for feeds 2,3,4, the hopper bottom is provided with 1 discharge port 5,2 main shafts that are parallel to each other 6 are installed in the hopper, 7, a plurality of blades 8 are installed on each main shaft, 9, described blade is arranged according to spiral-line, a main shaft wherein is by electric motor 10 process speed reduction units 11, small belt pulley 12 and big belt pulley 13 driven rotary, another root main shaft is by a pair of gear 14 driven rotary, two main shafts are provided with different rotating speeds, and the blade on two main shafts is set to different blade turning diameters and different blade revolving spiral lift angles, the cocurrent flow type structure of identical pitch.
Described hopper middle part is provided with the interlayer that leads to cold water with upper/lower positions, and described interlayer is respectively arranged with water inlet pipe 15 and rising pipe 16.
Described hopper top is provided with a venting port 17, and described venting port is provided with venting port plate 18.
Described hopper is provided with access hole 19.
Each component has maximum speed of relative movement to move in the material in order to make, and improves mixture homogeneity and puddles efficient, and two main shafts of the utility model adopt different rotating speeds, different blade turning diameter, different blade revolving spiral lift angles, the cocurrent flow type structure of identical pitch.
The interlayer of logical cold water is installed with upper/lower positions at the middle part of hopper, and water coolant enters from the bottom water inlet pipe mouth, flows out from the middle part effluent pipe mouth, to the cooling of lowering the temperature of the material in the spiral mixer.The high-temperature material, wood powder, flame-cooling agent etc. that contain compound oil phase and properties-correcting agent with quantitative conveyor screw respectively in three opening for feed adding machines.The blade that spiral-line is arranged is when main shaft gyration, and constantly to the material mixing stirring in the hopper, meanwhile, blade also draws off being transported to discharge port through well-beaten medicinal powder.
This vane-type twin shaft puddle coolconveyer be a kind of continous way puddle the cooling handling equipment, be fit to the needs of modified ammonium nitrate-fuel oil explosive serialization automatic production.
