Abstract
The present invention discloses a new improved mud juice separating technology of a vacuum nutsch filter without filter cloth, which solves the problems of huge equipment, large noise, easy clogging of pipelines, high cost and high operating expenditure because the technology needs a bagasse chaff pneumatic conveying system, a cyclone separator, an agitating tank and long-distance bagasse chaff taking. In addition, the technology also solves the problem of difficult sedimentation of tiny solid particles in filtered juice because neutralized juice and the filtered juice are not mixed. The new mud juice separating technology of a vacuum nutsch filter without filter cloth comprises a presser, a filtering screen, a mixed juice box, a neutralized juice box, a sedimentation tank, a vacuum nutsch filter without filter cloth, a juice pumping pot, a vacuum system, a juice pumping pump, a neutralized juice tube, a filtered juice tube and the like, wherein bagasse chaff does not need to be added to the mud juice flowing from the sedimentation tank, and the mud juice can be filtered by the vacuum nutsch filter without filter cloth. The new technology has the advantages of simple structure, low noise, low cost, low operating expenditure, small temperature difference between the neutralized juice and the filtered juice, and high sedimentation speed of the solid particles in liquid, and is suitable for the filtration of mud juice in the sugar production industry by utilizing sugarcane.
Description
Affiliated technical field
The present invention relates to a kind of improved mud and liquid for no filter-fabric vacuum nutsch filter separating technology, be particularly suitable for the separation of cane sugar industry mud juice.
Background technology
At present, the mud juice separating technology that known vacuum filter without cloth uses, employing flows into steel basin from the effusive mud juice of settling tank, simultaneously from packing machine or boiler house or the bagasse chaff sent here through blast system of bagasse chaff wind of milling shop enter steel basin and stir, flow into the mud juice groove of vacuum filter without cloth, under the acting in conjunction of vacuum filter without cloth and vacuum pump, solid particulate is retained down liquid in the suspension by the duct of stainless (steel) wire, thereby the realization solid-liquid separation, the filtered juice after the filtration flows to settling tank.Because of this technology not only needs blast system of bagasse chaff, and need long distance to get the bagasse chaff, cause that equipment is huge, noise is big, pipeline stifled, the cost of resistance and working cost is high and filtered juice temperature after filtering descends easily, especially under the colder situation of temperature, filtered juice is back in the settling tank and the defeco-sulfitated juice in the settling tank produces convection current because of the temperature difference, influences the solid particles sediment in defeco-sulfitated juice and the filtered juice.Defeco-sulfitated juice and filtered juice be through mixing in addition, small solid particulate free settling not in the filtered juice.
Summary of the invention
Technical problem to be solved by this invention is that a kind of improved mud and liquid for no filter-fabric vacuum nutsch filter separating technology will be provided, it neither needs blast system of bagasse chaff to realize solid-liquid separation, can improve the temperature of filtered juice again, after defeco-sulfitated juice combined balance system temperature, return settling tank, improve the settling velocity of solid particulate in the liquid.
The technical solution adopted for the present invention to solve the technical problems is: the mud and liquid for no filter-fabric vacuum nutsch filter separating technology is that the effusive mud juice of settling tank flows directly in the mud juice groove of vacuum filter without cloth, separate filtered juice and filter mud with vacuum filter without cloth, adjust the gap or the hole of squeezing system filtration sieve, the content that makes bagasse in the dry filter mud is 10%～40%, filter sieve is by bent sieve of one-level or trommel screen, the bent sieve of secondary is formed, bent sieve of one-level or trommel screen time of filtration are 2mm～5mm, the filter screen of the bent sieve of secondary adopts 80 orders with lower filter screen, between defeco-sulfitated juice pipe and filtered juice pipe and settling tank, connect the temperature equilibrium device, the temperature equilibrium device is by the temperature equilibrium jar, well heater is formed, at least one helical heating pipe is installed in the well heater, and adding hot heater with high-temperature steam, to make filtered juice and the temperature of defeco-sulfitated juice after the temperature equilibrium in-tank mixing be 95 ℃～105 ℃.
The principle of work of this mud juice separating technology is as follows:
1, the sugarcane juice after the squeezing flows into mixed juice case after the bent sieve of I and II filters, handle the back again and flow into neutralize juice tank, flows into settling tank after the second-heating.
2, the mud juice of settling tank flows in the mud juice groove of vacuum filter without cloth.
3, under the acting in conjunction of vacuum filter without cloth and vacuum pump, solid particulate is retained down liquid by the duct of stainless (steel) wire in the suspension, thereby realizes solid-liquid separation.
4, filtered juice flows into the temperature equilibrium jar through juice-drawing tank, surge tank, juice pump and filtered juice pipe, and the defeco-sulfitated juice of neutralize juice tank also flows into the temperature equilibrium jar through the defeco-sulfitated juice pipe, flows into settling tank after the combined balance system temperature again.
5, when the filtered juice temperature is lower than 80 ℃, high-temperature steam is sent in the helical heating pipe of well heater, make liquid at the well heater internal heating, flow into and flow into settling tank when temperature equilibrium jar and defeco-sulfitated juice combined balance system temperature reach 95 ℃～105 ℃ again.
The invention has the beneficial effects as follows, have simple in structure, noise is little, cost and working cost is low, defeco-sulfitated juice and filtered juice temperature head are little, the solid particles sediment speed in the liquid is fast, the separation of the most suitable cane sugar industry mud juice.
