Abstract
The utility model relates to a flour mill, which belongs to a crushing machine. A grinding disc which rotates horizontally and three grinding wheels which rotates passively. The three grinding wheels are supported symmetrically on the rotary grinding disc. The shovel blade structures which are used to scoop up materials are arranged on the rear part of each grinding wheel. Two hydraulic cylinder bodies which are pulled downwards are arranged on the support frame of each grinding wheel. A conical material divider is arranged on the center of the grinding disc. A replaceable antifriction lining board is arranged between the grinding wheels and the grinding disc. Air ducts are arranged on the circumference of the grinding disc. The utility model has the advantages of closed circuit structure, non pollution and power saving. The grinding and pressing force ranges from 10 tons to 20 tons. Compared with the traditional flour mill, the production efficiency is improved over twice. A high efficiency classifier and a host machine are linked to integration, which reduces 15 percent energy consumption of transportation, quadric pneumatic separation, etc.
Description
Technical field
The utility model relates to a kind of size reduction machinery, particularly a kind of new flour miller of energy-conservation, efficient, environmental protection.
Background technology
Present size reduction machinery both domestic and external can be divided into two classes: the first has the medium flour mill, and it two is no medium flour mills, is also referred to as autogenous tumbling mill.Raymond machine, vibromill, tube mill, ball mill etc. are for there being the medium flour mill; Airflow milling is no medium flour mill, is also referred to as autogenous tumbling mill.Airflow milling is a ultra micro powder manufacturing machine, and when＜1250 order abrasive dust scopes, specific energy consumption is very high mutually with other mechanical type flour mill, so the scope of application is limited.The general application is that the medium flour mill is arranged more widely.
Always having medium mill powder machine draws: grinding pressure is made up of mechanical force and gravity, suppressing flour mill at present is product best in the medium flour mill, its aux. pressure is to have increased to suppress the spring and the arm of force, thereby improved the grinding pressure of flour mill, grinding pressure can reach the 800-1200 kilogram, and efficient has improved 20-30%.
How to develop flour mill more efficiently, will design scientific and reasonable wind power system simultaneously from increasing grinding pressure, promptly increasing mechanical force and start with.
The utility model content
The purpose of this utility model provides and a kind ofly strengthens grinding pressure and have the flour mill of reasonable wind power system with hydraulic structure.
New flour miller, it is characterized in that: the emery wheel that is provided with a mill that horizontally rotates and three passive rotations in the flour mill, three emery wheel symmetric support and have certain inclination angle between the mill on rotating grinding board, be provided with the perching knife structure that material is scooped up at each emery wheel rear portion; Be provided with the hydraulic cylinder of two downward tension and compression on each emery wheel support, the hydraulic cylinder two ends are separately fixed on emery wheel support and the base; Be provided with tapered tripper in the middle of on mill, between emery wheel and mill, be provided with removable antiwear lining plate; Around mill, be provided with the air channel, be provided with grader, be provided with reductor, be connected with conveying worm on the top, mill chamber of flour mill in flour mill mill bottom on flour mill top.
Air channel, grader, grader upper air ducts around support air compartment, the mill, blower fan constitutes the air closed-loop path.
On blower fan outlet air pipeline, be provided with filter drum type precipitator.Purpose is to work under negative pressure for the assurance flour mill, adjusts air quantity, gets rid of moisture, and plays the dedusting effect.
The beneficial effects of the utility model are: the utility model can make the grinding pressure of flour mill reach the 10-20 ton owing to use downward hydraulic pressure pressure; Use the design of unique abrasive disk gas flow on every side, improved more than the production efficiency twice than traditional flour mill; Closed circuit structure, pollution-free, economize on electricity; Highly effective classifier and main frame join together, have reduced energy consumptions 15% such as transportation, secondary selection by winnowing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See Fig. 1, be provided with the emery wheel 9 of a mill that horizontally rotates 5 and three passive rotations in the flour mill, the emery wheel symmetric support and has certain inclination angle between the mill on rotating grinding board, be provided with perching knife 13 structures that material is scooped up at each emery wheel rear portion, perching knife is fixed on the main frame sidewall; Emery wheel support 6 is fixed on the support 4, is provided with the hydraulic cylinder 1 of two downward tension and compression on each emery wheel support 6, and hydraulic cylinder brings pressure to bear between emery wheel and the mill, also can adjust the size of pressure according to material hardness.
Be provided with motor 14 and reductor 2 in the device bottom, mill 5 is by reductor 2 transmissions.Antiwear lining plate 7 is housed in mill 5, and antiwear lining plate can be changed.Emery wheel with the material roll-in between itself and the mill liner plate, roll, consult broken.
Bulk materials is delivered in the material storage tube by elevator after the crusher in crushing granularity is less than 15mm, and it is indoor continuously, evenly, controllably to deliver to mill by conveying worm 11 again.By tapered tripper 8 material is delivered between emery wheel and the mill liner plate,, scooped up material, repeat the crushing process again by the back emery wheel to press by perching knife in roll-in, in the broken process that rolls, consults; Simultaneously, blower fan is blown into mill chamber along mill air channel 10 on every side from the porch with air in support air compartment 3, and perching knife 13 materials that scoop up, that be broken are taken in the grader 12, and large granular materials returns the mill chamber along the grinding machine inwall, pulverizes through secondary.Qualified fine powder then enters finished product with air-flow and revolves in the powder device; After fine powder and the air separation, discharge from discharge port, finished product.Air then returns blower fan from the upper end, repeats circulation last time.
In material, contain a certain amount of moisture, moisture is less than 15%, produce heat during grinding and cause water evaporates, and each pipeline imprecision of complete machine, ambient atmos is inhaled into, air circulation is constantly increased, under negative pressure, work for guaranteeing flour mill, the air quantity that is increased enters filter drum type precipitator by the residual air pipe between blower fan and the main frame, enters atmosphere after being cleaned.
