Abstract
The invention relates to the technical field of material conveying in pitch storage tank areas in the petrochemical and refining and chemical industry, in particular to a feeding device for a pitch storage tank. The feeding device comprises a cloth bag. The cloth bag is in a cylinder shape with openings in the two ends. The opening in the upper end of the cloth bag is fixed to a feeding port of the pitch storage tank, and the opening in the lower end of the cloth bag extends to the bottom of the pitch storage tank. A plurality of cloth bag sleeve openings are sequentially formed in the cloth bag in the cloth bag extending direction at intervals and are used for performing discharging. According to the feeding device for the pitch storage tank, due to the fact that the cloth bag is soft, the descending speed of pitch can be effectively reduced. A novel cloth bag sleeve opening structure is adopted, the bonding performance and sealing performance of pitch are well utilized, the cloth bag sleeve openings can be sealed through condensed pitch, disorderly drifting of light component substances flowing out of the pitch can be effectively controlled, explosive gases formed by disorderly drifting are avoided, and potential safety hazards are eliminated. Orderly and smooth unloading during pitch feeding is guaranteed through the multiple cloth bag sleeve openings.
Description
Technical field
The present invention relates to petrochemical industry, materials-handling technology field, Refining Chemical Industry asphalt storage district, especially relate to a kind of feed arrangement for asphalt storage.
Background technology
The pitchy complex mixture that pitch is made up of hydro-carbon and the non-metal derivant thereof of different molecular weight, pitch mainly can be divided into coal tar pitch, petroleum asphalt and natural asphalt three kinds.Wherein, coal tar pitch is the side production of coking, and petroleum asphalt is the residue after crude distillation, and natural asphalt is then be stored at underground, some formation ore beds or at earth's crust surface sediment.Pitch is a kind of full-bodied organic gel gel material, and normal temperature is when even temperature is below 70 DEG C, and pitch is solid-state or gelatinized, when temperature reaches asphalt melting after more than 90 DEG C, has good flowing power.Pitch is widely used in industrial circle and the surfacings etc. such as coating, plastics, rubber, and pitch with solid-state transport and storage, also can transport with liquid state conveying or groove tank, and with storage in liquid.
At field of industrial production, the asphaltic products produced by removing impurity or modification and the pitch as raw material use are transported mainly with liquid state conveying or groove tank greatly, and with storage in liquid.And from the above, no matter which kind of pitch, a certain amount of lightweight oil component is contained in capital, lightweight oil component in pitch is in the process of pitch by heat fused, in the process of pitch liquid state conveying, to constantly overflow, if the light component of effusion is assembled, inflammable, even can be quick-fried gas will be formed.Meanwhile, pitch is being carried with flow process with liquid state, because " friction " between material produces electrostatic, therefore, the transport of liquid asphalt exists larger potential safety hazard, the work must carried out electrostatic prevention work Yu prevent flammable explosive gas from assembling with conveying.
At petrochemical industry, Refining Chemical Industry, the bitumen feed of asphalt storage allows people " take great energy " and the thing of " on tenterhooks " exactly.The feed mode of asphalt storage is generally divided into " lower charging ", " upper feeding " two kinds of patterns.
As its name suggests, " lower charging " be the bottom mouth of pipe charging from storage tank.When pitch is inputted storage tank by " lower charging " pattern of employing, to make in storage tank material level lower than inlet point, the pitch in storage tank is made to be the liquid state after fusing entirely, otherwise, when material level exceeds inlet point, pitch is in solid-state or gelatinized, from the pitch of inlet point input need enough pressure break through be set in the mouth of pipe pitch or jacking pitch in storage tank just can be input in tank.Obviously, the powerful charging of the pressure by the pump housing often can cause transmission pump " to build the pressure ", damages transmission pump; And if to make in storage tank all (or major part) asphalt melting rear feeding, then require that in storage tank, heat exchanger is enough large, and the previous work time of charging is long, energy ezpenditure is many, is unfavorable for economical operation.
Therefore, in order to energy-conserving and environment-protective, usually adopt " upper feeding " pattern." upper feeding " is the top mouth of pipe charging from storage tank, adopts " upper feeding " pattern when pitch is inputted storage tank, no matter the height of liquid level in tank, also no matter pitch is gel state or liquid state in tank, all can charging, not be used in molten asphalt before charging, consume the energy, expend time in.But from the pitch in tank deck inflow tank because having the pitch of better flowing power, certainly for liquid, its temperature should more than 90 DEG C, and inflammable, can the be quick-fried light component material now evaporated in pitch is more, mix easily to form damp with air; In addition, the pitch fallen out and at a high speed by the upper feeding mouth of pipe, phase mutual friction very easily produces electrostatic; Thus " upper feeding " be not if take measures, and has very large safety problem equally.
Summary of the invention
The object of the present invention is to provide a kind of feed arrangement for asphalt storage, to solve the technical matterss such as the upper feeding pattern existed in prior art is safe not.
A kind of feed arrangement for asphalt storage provided by the invention, comprises cloth bag, and cloth bag is the tubular of both ends open, and the upper end open of cloth bag is fixed on the inlet point of asphalt storage, and lower ending opening extends to the bottom of asphalt storage; On cloth bag, along the direction that cloth bag extends, compartment of terrain is provided with multiple cloth bag cuff successively, and cloth bag cuff is used for discharging.
Further, the inlet point of asphalt storage is connected with steel short tube, and cloth bag is fixed on steel short tube; In cloth bag, be provided with metal guide current source, the upper end of metal guide current source is fixed on steel short tube, and lower end extends on the base plate of asphalt storage.
Further, metal guide current source is two, and two strip metal conductive chains are arranged in cloth bag symmetrically.
Further, two strip metal conductive chains and cloth bag are worked out and are integrated.
Further, between the bottom of cloth bag and the base plate of asphalt storage, there is interval, be spaced apart 300mm ~ 400mm.
Further, the diameter of cloth bag cuff is 100mm ~ 200mm, and length is 250mm ~ 350mm.
A kind of feed arrangement for asphalt storage provided by the invention, because cloth bag is the soft speed that can effectively reduce when pitch declines; Adopt novel cloth bag cuff structure, make use of adhesive property and the sealing property of pitch well, the pitch solidified can close cloth bag cuff, the unordered of Light ends material that can not only effectively control to overflow in pitch is flown away, avoid unorderedly flying away formation damp, eliminate safe hidden trouble, and when multiple cloth bag cuff ensure that bitumen feed in an orderly manner, gently discharging.
