Description

Rolling machine for ammonium chloride

The utility model relates to a kind of machinery that granular material is carried out rolling granulation processing, especially for the ammonium chloride rolling mill of chemical industry.

At present, the more representational machinery that is used for granular material is carried out rolling granulation processing is the 40 types～500 type rolling mills of U.S. Koppern company and the BK3-44～BMS-350 type calender of Japan, these two kinds of mechanical structures complexity, it is monolithic construction that operation requires height and critical piece roll, and maintenance and dismounting are all inconvenient, uses in practice and finds, granulating rate is low, the returning charge amount is big, easily causes environmental pollution, output to be difficult to reach the parameter of design code.

The purpose of this utility model is exactly at above-mentioned deficiency, proposes a kind of ammonium chloride rolling mill.

Technical solution of the present utility model is; connect by main motor and main gear reducer; main gear reducer connects with the active roll; active roll and the idle roll level that cooperates with its rolling are installed in the frame; it on the frame material mouth; initiatively the below of roll and idle roll is equipped with the electricity formula thresher that shakes; frame is a frame structure; it is characterized in that; adopted the pressurization cylinder system; cutter sweep; the pressurization cylinder system is by hydraulic control system; two pressurization oil cylinders are formed; two pressurization oil cylinders by the hydraulic control system control action are installed on the frame respectively; hydraulic arm on the pressurization oil cylinder directly cooperates with the sliding sleeve of supporting idle roll; sliding sleeve is contained in the slideway on the frame; cutter sweep is made up of vertical cutter and cross-cutter; vertically cutter is that jagged strip-cutting roller is formed by a pair of intermeshing cross section; be installed in initiatively roll and idle roll under; below vertical cutter, cross-cutter is housed; it is the cylinder that a cylindric surface is covered with cutting knife; idle roll and active roll are assembled roll structure; adorning roll sheath outward by the roll core constitutes; roll sheath is connected as a single entity with screw bolt and nut by two semicircle roll cases; material mouthful is an electric and magnetic oscillation material mouth, and the shake spring of the support plate on formula thresher and frame and the frame of electricity is connected.The frame of frame structure is an internal force formula framework.Main motor; electric and magnetic oscillation material mouth and electricity shake the formula thresher by ac power supply; hydraulic control system comprises the small-sized hydraulic pumping plant; executor; stop valve; bleeder valve; check valve; accumulator; high pressure air bottle and fuel tank; the small-sized hydraulic pumping plant respectively with fuel tank; Pressure gauge; check valve; bleeder valve links to each other; bleeder valve communicates with fuel tank; the check valve other end connects executor respectively; bleeder valve and be contained in bleeder valve and accumulator between stop valve one end; another termination accumulator of stop valve; accumulator and high pressure air bottle pass through stop valve; pipeline constitutes passage; Pressure gauge is housed on the high pressure air bottle; the output of controller links to each other with two pressurization oil cylinders respectively, and constitutes asphalt channel.Operation principle of the present utility model is, behind the main electric motor starting, the running of driving main gear reducer, drive initiatively roll rotation, thereby the idle roll that cooperates with the active roll is rotated, at this moment, pressurization cylinder system startup work, oil cylinder is produced the enough thrust of hydraulic arm, two hydraulic arms directly are pressurized to the thrust that oil cylinder produces on the contacted with it sliding sleeve, make the sliding sleeve of supporting idle roll stressedly do directed movement along slideway, thereby make idle roll stressed and pressure passed to initiatively on the roll and the contacted plane of rotation of idle roll, the granular material that enters in the frame when self-excited oscillation material mouth falls on the rotation contact-making surface of active roll and idle roll, to be subjected to huge extruding force, air in the granular material will be extruded, the particle of granular material will rearrange combination, eliminated mutual gap, the granular material particle that is subjected to high pressure simultaneously will obtain enough heats and form the clinkering chain, make the granular material plasticizing, reunite, condense, granular material through extruding becomes tablet, overflow from active roll and idle roll rotation contact-making surface below, under be advanced into cutter sweep, the vertical cutter cuts that is at first turned round is thing into strips, bar continues descending, promptly the cross-cutter that is turned round cuts into granular substance, and through the twice cutting action, the finished product of particle in 0.5～4mm is no less than 80% of processing materials total amount.And the material powder of＜0.5mm can be separated by vibratory sieve and return charging aperture reprocessing.

Advantage of the present utility model is, compact conformation is reasonable in design, the saving of labor, save time, laborsaving, reduced production cost.Adopt internal force formula framework, can guarantee to obtain very high roll compacting power, for overcoming the dismounting difficulty of existing machinery solid roll, taked fabricated roll structure, the change the outfit roll sheath of rapid wear of feasible dismounting is very convenient, adopt the pressurization cylinder system to provide easily and satisfy the required roll compacting power of complete machine, and the pressurization cylinder system can be by homemade device assembling, technology is reliable, reduced investment; The cutter sweep that adopts vertical cutter and cross-cutter to form, can fast hierarchical time ground will cut into granular product through the sheet material that critical piece active roll and idle roll squeeze out, the disintegrating machine that uses on this isolated plant and the existing external machine is compared, granulating rate improves 15-20%, thereby significantly reduced the returning charge amount, improved production efficiency; The electricity formula discharging machine that shakes is sent grain products outside the casing, is convenient to packing, and it is simple in structure low in energy consumption, can not cause the second-time breakage of particle and flying upward of dust; The utility model not only is used for the production of ammonium chloride particle product, also can be used for simultaneously the material of various ultralow moisture content (0.5-3%), crystalloid, plasticity and viscosity extreme difference is processed granulation, as processing, can really realize " do not have drying, no returning charge, nothing sieve, pollution-free " operation for the NPK mixed fertilizer.Of the present utility model applying will provide a kind of inexpensive, practical granulation process equipment for chemical fertilizer, chemical industry.
