Abstract
The invention discloses a sand conveying device of an air separation column, which is not required to be watched by people and is safe and reliable. The sand conveying device of the air separation column comprises a vacuum pump, a sand conveying pipeline and a sand box, wherein the sand box consists of a box body and an air dispensing box; a pipe orifice of the lower end of the air dispensing box is positioned above a bottom plate of the sand box, and is close to a sand outlet on the sand box; and the sand conveying pipeline is connected with the sand outlet on the sand box. By adopting the structure that the air dispensing box is arranged inside the sand box, when sand completely buries an inlet of the sand conveying pipeline in the sand box, the load of the vacuum pump is reduced through air dispensed by the air dispensing box, so that the sand conveying device of the air separation column is not required to be watched by a specially-assigned person, the amount of the sand brought into the sand box is not taken into account, and the vacuum pump is unlikely to be overloaded.
Description
Technical field
The present invention relates to a kind of sand conveying device.
Background technology
The pearlife of need packing into after the oxygen air separation column processed maintenance, the ways that adopt crane liftings or electric chain to carry are carried out the sand loading operation more during sand loading.These two kinds of sand loading operational methods, all need many from operation, not only the sand loading cycle long, and the danger of aloft work is also large, jeopardizes the life security of work.The vacuum draw mode of adopting is arranged, such as the conveying of grain in other shipping.The negative pressure that produces by vacuum pump sucks material in the delivery duct, sends to the destination.This mode has alleviated labour intensity greatly, and safe ready.But the problem that this mode exists is, when sucking material material buried the entrance of delivery pipe entirely, not so causes the vacuum pump load too high, and burns out motor.Therefore, except the dynamic operation delivery pipe suction inlet that carries out manual intervention, also must there be the special messenger to nurse.
Summary of the invention
The purpose of this invention is to provide a kind of artificial nurse and safe and reliable air separation column sand conveying device of not needing.
Technical scheme of the present invention is: comprise vacuum pump, sand delivering pipeline and sandbox, it is characterized in that: described sandbox is comprised of casing and aid distributing pipe, the aid distributing pipe lower end mouth of pipe is positioned at moulding plate top, and presses close to the sand export on the sandbox, and sand delivering pipeline is connected with sand export on the sandbox.
Adopt the structure of configuration aid distributing pipe in sandbox among the present invention, when sand with sandbox in the entrance of sediment transport pipe when entirely burying, by the wind of aid distributing pipe dispensing, the load that has alleviated vacuum pump.Therefore, do not need the special messenger to guard, need not take into account yet and be transported to what of sandbox medium sand, vacuum pump is not prone to extra-heavy situation.
Description of drawings
Fig. 1 is the front view of structure of the present invention.
Fig. 2 is the structural representation of cheek of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail, but does not consist of any limitation of the invention.Illustrated in figures 1 and 2, the present invention includes vacuum pump 1, sand delivering pipeline and sandbox, described sandbox is comprised of casing 3 and aid distributing pipe 4, aid distributing pipe 4 welds or is screwed onto on the casing 3, the lower end mouth of pipe of aid distributing pipe 4 is arranged in casing 3 and keeps at a certain distance away with casing 3 base plates, guarantee that simultaneously the lower end mouth of pipe of aid distributing pipe 4 and the sand export on the casing 3 press close to, make the effectively air that enters from aid distributing pipe 4 of inspiration of aid distributing pipe 4, sand delivering pipeline is connected with sand export on the casing 3, vacuum pump 1 is contained on the sediment transport pipe, and sediment transport pipe mouth is equipped with sand hopper 2.
During work, open vacuum pump 1, vacuum pump 1 sucks the sand in the casing 3 in the sediment transport pipe by negative pressure, and is transported to the top of air separation column, sends in the air separation column by sand hopper 2.In the process that sucks sand, because aid distributing pipe 4 upper ends communicate with atmosphere, the sand export of not being afraid of casing 3 buries, and therefore, does not need the special messenger to guard, and vacuum pump 1 is not prone to extra-heavy situation.Also can load onto by-pass valve control on the aid distributing pipe 4, adjusting air inflow quantity reaches the optimum matching with vacuum pump 1, further increases work efficiency.
In the practice, sand hopper 2 can adopt the spiral fashion cloth bag to replace.When the sediment transport amount is larger, because the mouth blast of vacuum pump 1 is larger, often cause that dust flies upward in the sand everywhere, operation field is produced serious dust pollution.After using the spiral fashion cloth bag, the blast major part can drain the hole from the cloth bag fabric, and sand moves downward by spiral fashion simultaneously, has increased time of run, has alleviated dust pollution.
