Description

A kind of movable crystallizing bed salt making equipment

The present invention relates to a kind of equipment of from contain bittern water, producing crude salt.

Before the present invention finishes, contain the bittern water beach by seawater or other and shine and produce crude salt, all at the bottom of the fixed crystallizing pond pond, carry out.Seawater progressively evaporates fresh water through exposing to the weather, and the xln of separating out salt then bleeds off bittern at the bottom of the pond, and go into the pond and break into rickle with wooden rake or take off respectively on pool side low bank between fields or the road, consolidated shipment again, packing appears on the scene.This salt extraction process, hundreds of Nian Erwu that have been continuous change at all, in recent years, along with progress of science and technology, developed powder salt successively, washing salt, product innovation and corresponding technologies such as refined salt and seasoning salt, but, then do not break away from crystalline category at the bottom of fixed spool all the time as from seawater, producing crude salt.

At present, general this salt making technology has following weak point:

1, to having relatively high expectations at the bottom of the crystalline pond, need the pottery sheet pave or plastic film rebasing, so investment is many, manufacture difficulty is bigger, ton salt is shared investment up to 120-160 unit.

2, need the workman to advance the pond operation, labour intensity is big, and efficient is low, and the equipment deterioration is serious, and ton salt production cost reaches 70-80 unit approximately.

3, interruption production efficiency is low, and bittern is in evaporative process, because of no relative movement, so the degree of supersaturation height influences bittern evaporation; When taking off salt, because of bleeding off bittern, need stop evaporative crystallization, also influence Salt Production.

4, advance the pond operation, cause product contamination.

Except that above-mentioned deficiency, the present invention says relatively, and main is to make crude salt by this technology, and from there not being special-purpose salt making equipment, people are employed only to be the instrument that substitutes of taking off salt, fortune salt and buttress salt.

The object of the present invention is to provide a kind of new special-purpose salt making equipment, it can overcome the deficiency of above-mentioned former instrument, can continuously make crude salt from bittern.

The objective of the invention is by changing over movable crystallizing bed the realization at the bottom of the fixed spool with former crystallizing pond.

The invention will be further described below in conjunction with accompanying drawing.

Major technique feature of the present invention is:

One movably crystallizing bed, and this crystallizing bed part is immersed in and contains in the bittern water (or seawater, down with), and another part is exposed in the air.Crystallizing bed is dead front type, and it is driven by a rotating mechanism, and it is mobile ceaselessly to circulate.

In schematic diagram shown in Figure 1, crystallizing bed 8 by motion-work wheel 10 driven rotary, crystallizing bed head and the tail pile warp motion-work wheel 10 and follow-up pulley 7 backs are closed together, in order to regulate the height that crystallizing bed bed surface top contains bittern water, bed surface is provided with halogen face regulating wheel 5 thereon, this regulating wheel of crystallizing bed pile warp, in order to maintain a certain distance at the bottom of the pond that makes crystallizing bed following bed surface and crystallizing pond 24, also in order to make crystallizing bed bed surface decide the path circulation by giving, ad hoc have a locating wheel 9, and crystallizing bed following bed surface promptly should wheel around the footpath.

Described regulating wheel and locating wheel are a length to pulley, just a regulating mechanism 23 respectively is set at the two ends of regulating wheel, the latter forms by regulating leading screw and support, support can be fixed on the pool side of crystallizing pond, shake the crank of leading screw, can reach the purpose (other regulating mechanism among the present invention, also all basic identical therewith) of adjusting.

The crystallization bed surface when mobile, will contain bittern water and be adsorbed on the bed surface in bittern, after shifting out bittern, evaporate fresh water because of exposing to the weather, and make salt burl crystalline substance on bed surface.The translational speed of crystallization control bed is promptly controlled the crystallization velocity and the particle diameter of salt.

The salt crystallization after on the bed surface, before moving into the pond heavily again, should be with under its brushing.For this reason, motion-work wheel tiltedly below, brush salt wheel (or scraping the salt plate) 11 is set, the hairbrush on the brush salt wheel contacts with crystallizing bed bed surface.Its sense of rotation should be advisable with the motion-work wheel switched in opposite.

During crystallization, if crystallization velocity is too fast, its particle diameter may be too big on bed surface for salt, if the production powder salt then should be established break wheel 12 in the side of motion-work wheel, the outside surface of break wheel presses mutually with crystallizing bed bed surface, when the break wheel load out-of-date, salt grain crushing that can will be bigger.The outside surface of break wheel is designed to mesh-like, and width of mesh is identical with the powder salt particle diameter that will produce.Certainly, also can be at the sticking silk screen that applies the required particle diameter of one deck of the outside surface of break wheel, this structure is easier to processing than annular knurl on the break wheel.

In crystallizing bed bed surface one side a tightening pulley 4 can be set, in order to regulate bed surface tension force.Tightening pulley is one long to pulley, respectively establishes a regulating mechanism 25 at its two ends, and regulating mechanism is formed by regulating leading screw and support, and rotating threaded shaft can be regulated the position of tightening pulley, thereby makes suitable tension force of crystallizing bed maintenance.

When raining, crystallizing bed in the salt making equipment also can be used for hiding rain, works the effect of covering with mat of moulding.For this reason, drive halogen wheel 6 in crystallizing bed establishing between the bed surface up and down, driving the two ends of halogen wheel fastens with traction rope 13, behind latter's pile warp pulley 15,16,17,18,19,20, an output shaft by variator 2 drives move left and right, when raining, can regulate the height of the face of going to bed, cooperate and drive moving of halogen wheel, just the bittern of going up on the bed surface can be driven in the crystallizing pond.Like this, topped on bittern on bed surface can play the effect of rain cover.And the penthouse on low bank between fields limit, pond then cooperates last bed surface that rainwater is directed at outside the crystallizing pond, drives the halogen wheel and can adopt light material to make, to alleviate driving power.

In order to regulate the height of crystallizing bed bed surface, horizontal length reaches angle of inclination etc., and each fixes a upper-lower position setter 21 and left and right sides position control 22 at the axle two ends of follow-up pulley 7.Described setter is formed by regulating leading screw and support, and support also is fixed on the pool side of crystallizing pond as described above like that.

Through variator 2 driven rotary, take turns by break by primover (as motor) 3 for motion-work wheel among the present invention, and brush salt wheel then can be by the belt driven rotary.

Crystallizing bedly play two effects at this device, the one, provide the crystallization place for producing salt, the 2nd, work the effect of covering with mat of moulding.For this reason, require its existing water-absorbent, again can waterproof.The material that can be used as bed surface has cotton, chemical fabric, reinforcement plastic cloth, plastic-coated fabric (or cloth mould Compound Fabric, such as canvas and plastic film are combined with each other), gummed cloth or the like.Crystallizing bed width is generally with wide 5-15 rice, and long 100-200 rice is advisable.Because the general broad of saltern crystallizing pond, so when adopting this device, several salt making equipments are linked side by side.

Each pulley of using among the present invention, can adopt metallic substance, timber, engineering plastics, glass reinforced plastic and rubber etc. to make such as motion-work wheel, follow-up pulley, tightening pulley etc., the diameter of motion-work wheel is advisable with 25-50 centimetre, follow-up pulley, and tightening pulleys etc. are advisable with diameter 10-35 centimetre.

When the present invention operates at the scene, at first should adjust the degree of depth of crystallizing pond bittern by the size of season and steam output, generally be advisable with the 5-20 centimetre of degree of depth, bittern concentration is controlled at the 20-30 degree Beaume.Adjust drum rotational speed then, crystallizing bed translational speed per minute is selected in 1-6 rice.Analyse the running of when 0.5-2 millimeter scope, starting shooting of salt thickness, when steam output is big for working continuously, vice versa is interrupted start, a crystallizing bed width is 0.7 meter, and length is 140 meters salt making equipment, and daily evaporation amount is 15 millimeters, translational speed is 3 meters/minute, average every are of product salt reaches 70 kilograms/hour, and particle diameter is 1 millimeter, and the physical and chemical index of product complies with the national standard requirements fully.

Adopt the present invention, stopping pregnancy salt between traditional can be become successive mechanize and produce, thereby produce automatically and the further deep processing of salt provides convenience for modernization.Product granularity is easy to control.Powder salt is once made, and need not to produce macrogranule salt row processing again, thereby has reduced unnecessary consumption and loss.After producing salt serialization production, can make full use of evaporation rate, and avoid losing because of the stopping production that discharging bittern causes, output can improve 30%, and crystallizing bed relative movement in bittern, has reduced the degree of supersaturation of bittern, has avoided dead slag.The present invention need not the workman and goes into the pond operation, just avoided polluting yet and received salt, the abrasion of taking off salt equipment does not have too harsh requirement to the quality standard and the routine maintenance of crystallizing pond yet, than making pottery, mould the crystallizing pond expense 40-60% that can reduce investment outlay, the salify cost reduces by 20%.But the rainproof tarpaulin of crystallizing bed also double as among the present invention is covered equipment with mat thereby need not to purchase to mould again, and this has also improved usage ratio of equipment.
