Abstract
The utility model relates to a bulk material dumper, in particular to a sealing device for the bulk material dumper for loading fine particles such as cements, slag powders, fly ashes in bulk, etc. into a transportation tank car. An air chamber (2) is arranged around the outer wall (1) of the guide hole of the steel rope; an air inlet (3) and an air spraying outlet (4) are arranged on the air chamber (2); the direction of the air spraying outlet (4) directs to the steel rope (5) arranged in the guide hole; an air curtain formed between the steel rope and the guide hole seals the guide hole. The utility model can make the air with certain pressure get into the air chamber through the air inlet and sprayed out of the air spraying outlet; the direction of the spraying points to the steel rope in the guide hole; the air curtain is formed between the steel rope and the guide hole to seal the guide hole, which can prevent the fine powders of the materials form flying out through the guide hole to ensure the normal work of the steel rope. The utility model has the advantages of reasonable structure, easy use, safety, environmental protection, material saving, etc.; besides, the canning environment for the bulk material and workers' working situation can be purified.
Description
Affiliated technical field:
The utility model relates to a kind of loose unpacked material delivery device, the bulk discharger sealing arrangement that the transportation tank car of particularly fine particles such as loose packed cement, slag powders, fly ash being packed into is used.
Background technology:
Fine particles such as loose packed cement, slag powders, fly ash need the bulk discharger transportation tank car of packing into from feed bin, used discharger generally is made up of discharging base pipe, circular platform type shell, circular platform type seal disc, steel rope, cylinder, discharging base pipe one end is communicated with feed bin, the other end aligns than small end face with the circular platform type shell, form discharging opening, the circular platform type seal disc is connected with cylinder by steel rope, rotate with the external force head roll, the circular platform type seal disc is risen or decline, open or seal the discharging opening that matches.There is following problem in the discharger of this structure: because steel rope need enter discharger from the outside, the steel rope pilot hole must be set on discharger, and steel rope often is in mobile status, giving tank car when filling with substance in bulk, the material fine powder is easy to outwards fly out from the pilot hole of steel rope, has not only wasted resource but also contaminated environment.
The utility model content:
The utility model purpose provides a kind of sealing arrangement of loose unpacked material discharger, stops the material fine powder to fly out from pilot hole, saves material, and protection and environment purification solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: air chamber is set around steel rope pilot hole outer wall, air chamber has gas access and gas vent, the emission direction of gas vent points to the steel rope in the pilot hole, the gas of ejection forms air curtain between steel rope and pilot hole, seal whole pilot hole.
The position of gas vent is arbitrarily on pilot hole, and the angle in the emission direction of gas vent and the pilot hole between the steel rope also is arbitrarily, and it is not parallel with it only to need to point to the interior steel rope of pilot hole.In order to improve sealing effectiveness, gas vent is arranged on pilot hole near transportation tank car in-to-in one side, angle in the emission direction of gas vent and the pilot hole between the steel rope is 40--85 °, and directive transportation tank car inside, forms air curtain at pilot hole near transportation tank car in-to-in one side.
Adopt the utility model, gas with certain pressure enters air chamber from the gas access of air chamber, and spray from gas vent, the direction of ejection is pointed to the steel rope in the pilot hole, between steel rope and pilot hole, form air curtain, the sealing pilot hole prevents that the material fine powder from outwards flying out by pilot hole, do not influence the normal operation of steel rope.
The utlity model has characteristics such as rational in infrastructure, environmental protection easy to use, safe, save material, purify the canned environment of loose unpacked material and workman's work situation.
Description of drawings:
Fig. 1 is the utility model example structure scheme drawing.
Among the figure: pilot hole outer wall 1, air chamber 2, gas access 3, gas vent 4, steel rope 5, shutoff valve 6, compression indicator 7, reducing valve 8, electromagnetic valve 9
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
Air chamber 2 is set around steel rope pilot hole outer wall 1, air chamber 2 has gas access 3 and gas vent 4, the emission direction of gas vent 4 points to the steel rope 5 in the pilot hole, the gas of ejection forms air curtain between steel rope and pilot hole, seal whole pilot hole, gas vent 4 is arranged on pilot hole near transportation tank car in-to-in one side, angle in the emission direction of gas vent and the pilot hole between the steel rope 5 is 45 °, and directive transportation tank car inside, form air curtain at pilot hole near transportation tank car in-to-in one side.This device also is provided with shutoff valve 6, compression indicator 7, reducing valve 8, electromagnetic valve 9, be communicated with the gas access of air chamber successively by gas pipe line, when the discharge valve of discharger is opened, discharging signal sends electromagnetic valve 9 simultaneously to, the electromagnetic valve action, 0.4-0.6Mpa pressurized air through reducing valve 8, compression indicator 7, shutoff valve 6, the gas access 3 of air chamber enters air chamber 2, gas with certain pressure is from gas vent 4 ejections, the direction of ejection is pointed to the steel rope 5 in the pilot hole, between steel rope and pilot hole, form air curtain, the sealing pilot hole prevents that the material fine powder from outwards flying out by pilot hole, and does not influence the normal operation of steel rope.
Claims (3)
1, a kind of sealing arrangement of loose unpacked material discharger, it is characterized in that around steel rope pilot hole outer wall (1), being provided with air chamber (2), air chamber (2) has gas access (3) and gas vent (4), the emission direction of gas vent (4) points to the steel rope (5) in the pilot hole, the gas of ejection forms air curtain between steel rope and pilot hole, seal whole pilot hole.
2, according to the sealing arrangement of the described loose unpacked material discharger of claim 1, it is characterized in that gas vent (4) is arranged on pilot hole near transportation tank car in-to-in one side, angle between the steel rope in the emission direction of gas vent and the pilot hole (5) is 40--85 °, and directive transportation tank car inside, form air curtain at pilot hole near transportation tank car in-to-in one side.
