Description
Technical field
The present invention relates to a kind of solid disintegrating apparatus, relate in particular to a kind of sealing powder crushing device that is used for industrial solid caustic soda (caustic soda, caustic potash).
Background technology
Caustic soda, caustic potash all are important basic chemical raw materials, and very strong hygroscopicity and very strong corrosivity are all arranged.The primary raw material form has two kinds of solid block and sheets, generally packs with metal bucket, and also useful laminated plastics woven bag adds the sealing plastics package.In some fine chemistry industry, in the production of nonferrous metal product, need to use powder alkali, for guaranteeing the requirement of production technology, the maximum particle size of ground caustic and particle size distribution must satisfy certain requirement could guarantee fast reaction speed, improves synthetic grade, reduces the content of free alkali.But because caustic soda, caustic potash have very strong hygroscopicity and corrosivity, and the air that is mixed with ground caustic has strong smothering action, and therefore still there are a lot of problems in the comminution process of industrial solid caustic soda.
At present, the pulverizing of industry solid caustic soda mainly contains dual mode: a kind of mode that adds selection by winnowing for ball mill, as by the general milling machine, add the closed circuit circulatory system that two stage cyclone deduster and supporting blower fan pipeline are formed, operating type is after reinforced in batches (if raw material adds after need manually smashing for big block again) that ball mill is airtight, under the circulation wind action, bring the ground caustic of having pulverized into the one-level cyclone dust collectors, the raw meal particle size of collection is thicker, returns grinding machine by pipeline and pulverizes again; The material that second cyclone dust extractor is collected is collected in the finished product batch can of second cyclone dust extractor below, by artificial periodic replacement finished product batch can as finished product.It is recycling that the air communication piping that contains thin ground caustic that the secondary whirlwind is discharged enters ball mill.The finished weight to be collected and the finished weight of adding near the time, even if finish one batch operation, carry out the powder alkali operation of next batch then.The main in actual applications problem of this mode is; because a large amount of wind circulations is arranged; accomplish comparatively difficulty of totally-enclosed operation; always exist air-flow exchange with atmosphere; the problem of bringing is; because entering of fresh air; be easy to one; condense ground caustic on the inwall of second cyclone dust extractor and the pipeline; As time goes on; the ground caustic that is attached on the tube wall can harden because of the moisture absorption; solidify, and adhesive strength is very high, causes the cyclone dust collectors internal diameter more and more littler; cause the material quantity of the catch (return and reface) of one-level whirlwind increasing; and the quantity of the catch of second cyclone dust extractor (finished product) is relatively more and more littler, and directly reflection is exactly that output is more and more lower, and product is more and more thinner; crush efficiency significantly reduces, and has to shut down carry out difficult labor cleaning.Can cause operating environment to worsen in addition.
Another kind adds the air floated mode of circulation for the rotor pulverizer.As add the circulation crushing system that two stage cyclone deduster and supporting blower fan and pipeline etc. are formed by the rotor pulverizer.It is different with first kind that this cover system removes the pulverizing mode, but outside the continuous charging, other is all similar to first kind, and the problem of existence is also similar to first kind.Problem even more serious in some aspects.Rod hammer as grinding rotor.Because the superincumbent easier inefficacy of hardening of ground caustic, the producer that has even added heating, the drying device of wind in air circulating system also can't ordinary production in wet weather relatively.
Summary of the invention
The present invention is directed to deficiency of the prior art proposed a kind of environmental protection, efficient, material is lossless, do not need circulated air, even if enclosed crushing system and device that also can the continuous high-efficient operation under the very big weather conditions of air humidity.
This programme is realized by following technical measures: a kind of enclosed crushing system that is used for crushing caustic soda, it is characterized in that it is made up of the former feed bin of enclosed type, charging gear and vibrating mill, the former feed bin outlet of described enclosed type is connected with the charging gear import, described charging gear outlet is connected with the vibrating mill import, and the former feed bin of described enclosed type, charging gear and vibrating mill have formed airtight material channel.
The beneficial effect of this programme can learn that the present invention comprises the former feed bin of closure, charging gear, vibrating mill (pulverizer) and finished bin etc. according to the narration to such scheme.Be tightly connected between each device unit, be connected flexible pipe with high resiliency between metering device and vibrating mill, vibrating mill and the finished bin and be tightly connected.With raw material (industrial solid caustic soda, as be big block raw material, should in advance it be crushed to certain particle size) add to former feed bin in batches, after former feed bin is airtight, raw material evenly adds in the vibrating mill continuously by metering device, and the material after the pulverizing enters finished bin by connecting flexible pipe.
Native system there is no sieve, grading plant, but the finished product granularity still can satisfy user's technological requirement, realize in the following manner: by regulating the vibration parameters of vibrating mill (or vibrating pulverizer), as Oscillation Amplitude, just can regulate the milling capacity and the product granularity of vibrating mill, the disposal ability of the big or small decision systems by regulating the charging gear feeding coal, that is in a set enclosed crushing system, necessarily contain output and granularity that a rational treating capacity and corresponding vibration parameters are complementary and reach technological requirement, thereby realize that no grading plant also can realize the purpose of output controllable granularity, this has promptly simplified crushing system, reduced cost, improved the reliability of system again, the fault rate of reducing the link.Be a kind of be the practical again crushing system of economy.
The invention solves enterprise and pulverize the needed ground caustic of industrial caustic soda, solved some enterprise's powder alkali equipment accumulated powders, efficient is low, working environment is inferior system process; Improve working condition, improved operating efficiency, reduced production cost.Therefore the present invention has compared with prior art realized technical purpose.
The concrete characteristics of this programme also have, and are provided with feeding tube and discharging valve in described vibrating mill outlet.In the described bleeder valve airtight enclosed type finished bin that is connected with of face behind the door, prevent that the material moisture absorption and atmosphere from invading crushing system.Be connected by flexible pipe is airtight between the outlet of described charging gear and the vibrating mill import, get final product the closed conveying material, can reduce the interference that vibrating mill is vibrated again.Be connected by flexible pipe is airtight between the outlet of described vibrating mill and the discharging valve, get final product the closed conveying material, can reduce the interference that vibrating mill is vibrated again.In the former feed bin of described enclosed type, be provided with vibration flow-aid device or mechanical flow-aiding device, prevent the bridging of material knot arch, guarantee that materials flow is continuous, prevent to accumulate in the feed bin material.Described vibration flow-aid device is to have the vibrator that utilizes vibration wave to destroy the stability of arch and activate the material function.Described mechanical flow-aiding device is the agitator with broken arch function.
