Description

Pre-immersion unit for early-rotation lixiviation device

The utility model relates to grain and oil processing, the flat-turn leacher that is used to leach legal system oil increase oil, the swollen material of solution leacher material lattice not the blanking fault give the equipment of soaking.

China's grease processing industry leaches legal system oil mechanical means and is made up of flat-turn leacher, feeding packing auger, spray equipment.Exist following several respects problem in the production:

The oil yield that leaches legal system oil is directly proportional with extraction time, and the flat-turn leacher capacity is fixed, and prolonging extraction time can influence output, must be directed at the oil yield reduction if the shortening extraction time improves output.Be 90-120 minute the running period of flat-turn leacher, removes loading and unloading material and drip-dry time, only has 60-80 minute and be pure extraction time.This body structure of flat-turn leacher can not be according to material embryo character, and the infiltration situation of different steps and the concentration of mixing oil are adjusted mixing oil spray flux and temperature, cause bigger concentration difference in early days.Dregs of rice Residual oil just differs more than 1%.When the high moisture content soybean of processing, to give the treatment plant drying dewatering limited in one's ability because of each factory, and high moisture content material embryo is gone into to soak flat-turn leacher and expected not blanking fault of the swollen material of lattice easily, has only in the past with manually disclosing, and labour intensity is big, solvent gas leaks, and is dangerous very big.Cause production line band material to shut down, make quality product reduce cost up.Flat-turn leacher soaks soybean, and miscella concentration is low, and the vapo(u)rization system working load is big, leaches crude oil residual solvent amount height, waste coal, electricity, solvent oil equal energy source.As reduce the novel solvent spray flux and improve miscella concentration, dregs of rice resid amount height.In sum, several indexs of flat-turn leacher interact, and attend to one thing and lose sight of another easily, can't accomplish to improve simultaneously.

The purpose of this utility model is to provide a kind of giving to soak device, by giving soaking to handle every index is independent of each other.Reach the purpose that improves oil yield, raising output, raising miscella concentration, reduces various energy consumptions.Solve the high moisture content of soybean and go into to soak, stop flat-turn leacher not blanking fault of swollen material takes place.Avoid disclosing unsafe factor generations such as the material lattice cause that solvent gas leaks.Solve mixing oil band dregs of rice end problem, improve the performance of enterprises.

The utility model is to have one to soak case, scraper plate drawing mechanism and filter giving that settling pocket constitutes and soak device by giving between flat-turn leacher and feeding packing auger.Give that to soak device be the square container, be installed in flat-turn leacher top, opening for feed is arranged at its top, is communicated with the feeding packing auger discharge port.Material separating disc is arranged at the opening for feed bottom, makes material embryo homodisperse.Be respectively equipped with surplus valve, liquid level replenishment valve, free gas pipe, pressure warning unit on the case and the liquid level material level is observed visor giving soaking.Give soak the spray mode for the mixing oil that comes out by leacher through spray pump heats temperature adjustment in course of conveying after, soak the box top and spray into from giving, will expect that embryo all soaks.Give that to soak lower box part be the stepless speed regulation drawing mechanism, will give the material embryo that soaks the standard of reaching by its multidigit opening for feed and constantly export, make to give and soak that the input and output material embryo keeps running balance in the case.Filter settling pocket and soak lower box part giving, adjacent with discharging screeding device afterbody, form by filtering sieve plate, traverse baffle, bolting silk, throttling valve, blow-off valve, residual cake valve etc.

In the immersion oil operation, the material embryo is given by the feeding packing auger input and soaks homodisperse in the case, in the material embryo of packing into, spray into through heating thermoregulated mixing oil, to expect that embryo all soaks, the material embryo can be taken 30 minutes in giving soaking in the case, give and soak the case liquid level and can overflow from surplus valve when too high and get back to the leacher, the free gas of generation enters the leacher condenser system.Drawing mechanism will expect that embryo is transported in the flat-turn leacher after the material embryo gives and soaks the standard of reaching, and it is carried material and highly soaks the case liquid level above giving.Mention elevated material embryo and enter flat-turn leacher charging lattice through stream material pipe, reduce by high potential difference and mix a large amount of leachers, mixing oil filters the sedimentation of traverse baffle baffling through filtering the settling pocket screen plate.The silk cover filtering sedimentation makes stability of flow flow to vapo(u)rization system by the throttle valve control miscella concentration.The valve time opening that filters the settling pocket bottom enters flat-turn leacher charging lattice with dregs of rice end.

Compared with the prior art the utility model has relative prolongation extraction time, and material embryo and mixing oil dynamically fully connect really, about 40% grease in the extraction discharging embryo.Give soaking and expect that afterwards the embryo oleaginousness is low, viscosity is low, good penetrability.The surface concn gradient is big.High moisture content material embryo reaches the expansion limit through giving soaking, and enters no longer to expand behind the flat-turn leacher and not blanking fault occurs.Go into to soak material embryo moisture content and can reach about 12%, reduce and give investment of treatment plant precipitation apparatus and energy consumption, give the mixing oil that soaks back devaporation system and do not contain dregs of rice end, concentration can reach 28%, and processing output can improve more than 20%, improves oil yield more than 0.3%.Reducing the various energy consumes.Avoid disclosing solvent gas that the material lattice cause unsafe factor such as leak.
