Description
Technical field
The utility model relates to a kind of air bubble.
Background technology
Air bubble is the isolated plant that prevents and eliminate phenomenons such as material arch camber in the containers such as all kinds of feed bins, hopper and pipeline, obstruction, sticking wall, delay, is applicable to the occasion of various storage dress loose unpacked materials.Existing air bubble comprises storage tank, and storage tank one side is connected with air inlet pipe, and the cylinder opposite side is connected with the flange of giving vent to anger through gun tube, and the flange of giving vent to anger is used to connect jet pipe; Jet pipe is fixed on the walls of a container such as feed bin, hopper during use.The principle of work of air bubble is that the flow of the compressed gas of at high speed ejection directly pours the inaccessible faulty section of storing bulk material, relies on the impulsive force of pressure gas to overcome the static friction of material in feed bin, hopper or pipeline, makes material recover to flow.
The technological characteristics of conventional air big gun is following:
Maximum working pressure (being the top pressure in the storage tank) :≤0.8Mpa (MPa);
Design top pressure (being higher than maximum working pressure): 0.84-0.88 Mpa;
Working temperature range: 0-120 ℃; The design temperature upper limit: 150 ℃;
Material of main part: Q235B.
Meeting under the prerequisite of above-mentioned technological characteristics, the specification of the existing air bubble of tradition has: Φ 350 Х 3.5 (millimeter), Φ 400 Х 3.5, Φ 500 Х 3.5, Φ 600 Х 4, Φ 700 Х 5.
The defective of existing air bubble has:
When 1, pressure is lower than 0.4 Mpa, cisco unity malfunction; Traditional solution is to be air bubble configuration air compressor, with boost in pressure to more than the 0.4Mpa.The defective of this solution is bigger, and the one, cost is high, because Air compressor costs an arm and a leg; The 2nd, the big weight of Air compressor volume is big, and installation, dismounting and transportation are very inconvenient, and floor area is also bigger after installing.
When 2, pressure is higher than 0.8 Mpa, cisco unity malfunction; The present technique field does not have corresponding solution now.
When 3, temperature is lower than 0 ℃, cisco unity malfunction; The present technique field does not have corresponding solution now.
Have two kinds of following technological prejudice in the art for a long time: 1. be lower than 0.4 Mpa at pressure, need to increase the air bubble pressure applications, must use air compressor.The applicant with go together exchange in the middle of, participate in various places recognizing in the business activity such as bid; When customer requirement increases the pressure of air bubble; Those skilled in the art can advise that the user is an air bubble configuration Air compressor, has no technical personnel to propose other technical scheme.This use Air compressor is to increase the practice of air bubble pressure; The habituation that has become those skilled in the art is selected; Become the industry habitual solution unique, that acquiescence is current, this kind solution is very ripe, also is accepted as default scheme by the terminal user.2. the material of making air bubble must use the material of specific thickness in the national standard (mostly Q235B type structural carbon steel, its thickness are 3.5 millimeters, and 5 millimeters of maximums are referring to the specification of the existing air bubble of above-mentioned tradition).Wall thickness is limited to have determined that the bearing capacity of air bubble is limited, and the pressure in the existing air bubble storage tank is 0.8Mpa (MPa) to the maximum.This present situation has caused the air bubble speed of giving vent to anger limited, when the installation site of jet pipe when container discharging opening distance surpasses 2500 millimeters, can't solve material blockage problem (being that gas shock power is not enough to overcome the static friction force of material in container).Simultaneously, be necessary for the so technological prejudice of Q235B type structural carbon steel owing to exist to make the material of main part that air bubble uses, therefore existing air bubble all can not (be lower than zero degree) at low temperatures and uses.
The existence of above-mentioned technological prejudice has stoped those skilled in the art to pursue more excellent technical scheme, makes above-mentioned defective long-term existence and can't improve.
