The utility model discloses a feeding system for a mechanical ultra-fine pulverizer for producing chemical fiber titanium dioxide, aiming to improve the productivity of the pulverizer and reduce the economic loss of the pulverizer. The feeding system comprises a driving mechanism, a coupler and the pulverizer with a hopper and spiral impeller blades. The feeding system has the following key points: the driving mechanism is a cycloidal pin wheel reducer, and the cycloidal pin wheel reducer is connected with a rotary main shaft of the pulverizer through the coupler. The feeding system has the beneficial effects that after the driving mechanism of the feeding system for the mechanical ultra-fine pulverizer is modified, a feeding screw can be driven by the driving mechanism in the revolving speed range required by production, the feeding is stable and uniform, the granularity of products is guaranteed, the quantity of scrap caused by equipment failure is reduced, based on the modification, the average annual scrap loss saved by each equipment is about 60,000 yuan, 200,000 yuan in total is saved annually, and the economic benefit is improved.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of atomizer feed system, particularly a kind of pulverizer feed system of increasing economic efficiency of chemical fibre of titanium dioxide production usefulness.
Background technology
The chemical fibre delustring has with the production process of titanium white powder: the clarifying process of powder, and promptly dissolving precipitate nucleation becomes powder particle; The dispersion of powder, surface modification and microcapsules overlay film process; The dry run of powder; The pulverizing of powder and collection process.At present, the pulverizing of powder is a very important link in producing, because it has directly determined the size of product.In the titanium powder industry, the high velocity air crushing technology is the direction of Future Development now.
The medium that air-flow is pulverized has: compressed air, superheated steam and inert gas.The chemical fibre delustring with titanium white production technology in; Because carrying out the air-flow pulverizing with compressed air can make electrostatic charge on the titanium white powder powder secondary band, may make different electric charges on the powder particle band, thereby finished product is reunited; Influence the fineness of product, the also corresponding increase of equipment investment; Then can eliminate above-mentioned unfavorable factor with superheated steam; Yet the superheat steam temperature the best that gets into airslide disintegrating mill will be more than 300 ℃; About steam pressure 1. 0 MPa, could guarantee the gatherer Outlet Gas Temperature more than dew point, such temperature is very unfavorable again to interfacial agent; Technological process relative complex, equipment investment also increase greatly.
The feeding serew kind of drive of the prior art is passed through belt for the 3KW variable-frequency motor, drives worm-gear speed reducer, drives feeding serew through shaft coupling again and rotates, and is as shown in Figure 1.When this feed system is lower than 120r/min when the variable-frequency motor rotating speed,, be with motionless feeding serew because driving torque is less; When variable-frequency motor rotating speed during greater than 120r/min, transmission device can drive feeding serew, but the equipment feeding so the Frequency Drive device can't satisfy instructions for use, causes feeding unstable greater than the production capacity of attritioning main frame, influences the granularity of product.
Summary of the invention
The purpose of the utility model is in order to improve the production capacity of pulverizer; Reduce the economic attrition of pulverizer; Driving mechanism is improved; Original feeding serew transmission device, turbine and worm decelerator are removed, changed into the cycloidal planetary gear speed reducer that drive mechanism is compact more, driving torque is big, directly drive feeding serew.
The technical scheme that the utility model adopts is; A kind of chemical fibre of titanium dioxide machine for producing tool formula micronizer feed system; Comprise driving mechanism, shaft coupling and have hopper and the pulverizer of helical runner blade; Key is: described driving mechanism is a cycloidal planetary gear speed reducer, and cycloidal planetary gear speed reducer is connected with the rotary main shaft of pulverizer by shaft coupling.
The beneficial effect of the utility model is, after the driving mechanism of mechanical type micronizer feed system is transformed, in the range of speeds of production requirement; All can drive feeding serew, feeding is stable, even, and product granularity has obtained guarantee; Reduced the amount of waste material that equipment fault produces; Only this transforms every equipment and can practice thrift about 60,000 yuan of scrap piece loss every year, amounts to more than 20 ten thousand yuan of annual saving, increases economic efficiency.

The specific embodiment
Referring to Fig. 2; A kind of chemical fibre of titanium dioxide machine for producing tool formula micronizer feed system; Comprise driving mechanism, shaft coupling 2 and have hopper 3-1 and the pulverizer 3 of helical runner blade 3-2; Key is: described driving mechanism is a cycloidal planetary gear speed reducer 1, and cycloidal planetary gear speed reducer 1 is connected with the rotary main shaft 3-3 of pulverizer 3 by shaft coupling 2.
The windup-degree of described helical runner blade 3-2 is 20-40 °.
Referring to Fig. 1; Available technology adopting variable-frequency motor 4 passes through belt; Drive worm-gear speed reducer 5, drive screw spindle 3-3 through shaft coupling 2 again and rotate, the utility model is that cycloidal planetary gear speed reducer 1 YWD14-14-1.5 has been replaced the combining structure of variable-frequency motor 4 with worm-gear speed reducer 5.
The ultra-fine crusher of mechanical type of the utility model design is by support, casing, the two ends horizontal spindle by the bearing supporting, and the some helical runner blade 3-2 that are contained on the rotary main shaft 3-3 constitute, and carries out high speed through motor direct connection main shaft and rotates.Its pulverization principle is: from the 0.14mm100 purpose titanium white powder particle of spray dryer; Quantitatively add in the pulverizing chamber continuously by feeder; Helical runner blade 3-2 has 30 ° torsion angle; Help to form the rotation blast, the helical runner blade 3-2 of back segment does not have torsion angle, forms gas-flow resistance.The blast that the helical runner blade 3-2 of leading portion forms causes the air-flow circulation in pulverizing chamber, impacts each other between the particle, collides, rubs, shears; Receive centrifugal action simultaneously, the granule impact inwall receives bump, friction, shears, and is ground into fine powder times without number, and like this, coarse granule is pulverized with the new material that adds at leading portion continuously, and fine powder is tending towards the air-flow center, is siphoned away by blower fan, collects through the cloth bag gatherer.The granularity of milling product can be controlled through regulating the pulverizer air quantity.The granularity of milling product increases with air quantity, and output also increases thereupon.
