Abstract
The utility model discloses a negative pressure emptying device for unloading a ship, which comprises a bracket on which drum-like loading heads are arranged. Reducer pipes with small end outward are fixedly communicated with top openings of the loading heads. An annular wall of each of the loading heads is communicated with a plurality of branch pipes. Each of the branch pipes is respectively connected with a soft tube through a quick connector. The end of each soft tube is respectively connected with a suction head. The emptying device works by making full use of equipment of a negative pressure pneumatic system without the aid of other auxiliary devices. The emptying device which is economically designed is convenient to detach and easy to operate, and the emptying efficiency is improved by more than 50% and labor intensity is greatly reduced compared with other emptying methods.
Description
Technical field:
The utility model relates to a kind of negative pressure unload a ship SUPPLEMENTARY UNLOADING GRAIN, particularly a kind of equipment of bringing down stocks of negative-pressure pneumatic transmission system.
Background technology:
The negative-pressure pneumatic transmission system principle is: by the getter action of source of the gas machinery, in system, form certain degree of vacuum, thereby form certain suction at the suction nozzle place that contacts with material, material is passed through a kind of Pneumatic conveyer of ducting certain distance from the somewhere.Negative pressure strength ship-unloading system is in actual practicality, when the material of piling up in the cabin abundant when saturated, system works efficient is higher, but continuous minimizing along with material, unloading efficient is also reducing gradually, especially when material only accounted for 20% left and right sides of storage area, system effectiveness just sharply reduced, and the average conveying energy consumption of unit material obviously rises.
Just need bring down stocks work with the mode of accessory machinery or hand sweeping this moment, brings down stocks in this section that the spent time accounts for about 30% of whole work-hours greatly in the work.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of reduced investment to be provided, and easy to operate, labour intensity is low, brings down stocks the high negative pressure of the efficient SUPPLEMENTARY UNLOADING GRAIN of unloading a ship.
The utility model is achieved through the following technical solutions:
A kind of negative pressure SUPPLEMENTARY UNLOADING GRAIN of unloading a ship, it is characterized in that: include bearing, be fixed with the head that gathers materials of tubular on the described bearing, fixedly be communicated with adapter bonnet on the described head opening that gathers materials, the osculum of described adapter bonnet is outside; Be communicated with some being in charge of on the ring wall of the described head that gathers materials, each is in charge of respectively and is connected with flexible pipe by quick coupling, and each hose end is connected with suction nozzle respectively.
Described a kind of negative pressure SUPPLEMENTARY UNLOADING GRAIN of unloading a ship is characterized in that: described adapter bonnet overcoat rubber sleeve.
Described a kind of negative pressure SUPPLEMENTARY UNLOADING GRAIN of unloading a ship is characterized in that: each is in charge of and is separately installed with shutoff valve.
Described a kind of negative pressure SUPPLEMENTARY UNLOADING GRAIN of unloading a ship is characterized in that: the described head and be in charge of and all adopt wear-resistant steel pipe of gathering materials; Described flexible pipe is a rubber bellows, and described suction nozzle adopts wear-resistant plastic or alloy in lightweight material.
When using the utility model, the utility model is connected in negative pressure unloads a ship on the mechanical arm of air-transport system, make it can be along with mechanical arm moves together; Simultaneously, described adapter bonnet is plugged on the suction nozzle of negative pressure Pneumatic conveying pipeline.
When the clearance job process begins, at first flexible pipe and suction nozzle being connected on the head that gathers materials each by fast connection orchid is in charge of, be fixed on the suction nozzle of negative-pressure pneumatic transmission system by clamp flange then, and be linked together with the unload a ship mechanical arm of air-transport system of negative pressure, re-using this mechanical arm unloads a ship with whole negative pressure that SUPPLEMENTARY UNLOADING GRAIN is sling and moves and be placed in the storehouse, the material such as the cement that are cleaned, fly ash, breeze, coal dust, corn, wheat etc., material is sucked by flexible pipe by suction nozzle and carries and converge to the head that gathers materials under the suction of negative-pressure pneumatic transmission system, gather materials head by adapter bonnet and negative-pressure pneumatic transmission system UNICOM, and material can enter the negative pressure strength by this device and carry main system.In cleaning process, can open and close each by shutoff valve and be in charge of and regulate the aperture that each is in charge of, can guarantee that other are in charge of when cleaning not to be in charge of because of certain leaks out and can't normal operation in a large number.When connecting with negative-pressure pneumatic transmission system, adapter bonnet guarantees its no leak when working by sealing rubber cover.
Head gathers materials in the utility model, be in charge of, flexible pipe, suction nozzle are base portion, the 2-4 that is made up of suction nozzle and flexible pipe props up suction nozzle and is distributed in purging zone and works simultaneously, be adjusted to metastable situation by control cock on the suction nozzle and shutoff valve with solid-gas ratio this moment, also can the suction of part suction nozzle, all the other suction nozzle temporary closes realize the alternate turns operation.
The utility model has the advantages that:
The utility model device need not to increase other accessory equipments, brings down stocks work by the equipment that makes full use of negative-pressure pneumatic transmission system; Easy with this device installing/dismounting of mode design-calculated of reducing investment outlay most, operation is easily simple; Can improve and bring down stocks efficient more than 50%, and labour intensity there is reduction significantly than other modes of bringing down stocks.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to accompanying drawing.
A kind of negative pressure SUPPLEMENTARY UNLOADING GRAIN of unloading a ship includes bearing 10, and what be fixed with tubular on the described bearing 10 gathers materials 4, fixedly is communicated with adapter bonnet 2 in described 4 open top of gathering materials, and the osculum of described adapter bonnet 2 is outside; Adapter bonnet 2 overcoat rubber sleeves 1.Be communicated with 4 on described 4 the ring wall of gathering materials and be in charge of 5, each is in charge of and is separately installed with shutoff valve 6 on 5.Each is in charge of 5 and is connected with flexible pipe 8 by quick coupling 7 respectively, and each flexible pipe 8 end is connected with suction nozzle 9 respectively.Describedly gather materials 4 and be in charge of 5 and all adopt wear-resistant steel pipe; Described flexible pipe 8 is a rubber bellows, and described suction nozzle 9 adopts wear-resistant plastic or alloy in lightweight material.
When the clearance job process begins, at first flexible pipe 8 and suction nozzle 9 being connected on 4 each of gathering materials by quick union 7 is in charge of on 5, be fixed on the suction nozzle of negative-pressure pneumatic transmission system by clamp flange 3 then, and be linked together with the unload a ship mechanical arm of air-transport system of negative pressure.
