Abstract
The utility model relates to a high-efficiency and energy-saving fan coal mill applied in the industry. The mill is provided with a base. The base is equipped with a fan and a bearing seat. The bearing seat is equipped with a transmission shaft which is connected with an electric motor via a shaft coupling. One end of the base is equipped with a fan mill body which comprises a machine shell. The inner circumferential surface is equipped with an inner lining. An impeller is arranged is arranged inside the machine shell and is equipped with an impact plate. The impeller is connected with the transmission shaft. The utility model is characterized in that a plurality of bosses are designed on the impact plate arranged on the impeller opposite to the material impact surface; the utility model increases the material impact area and times and settles the problem that coal powder from an imported fan mill is uneven in the outlet, the fineness is inadequate, the structure is complicated and the installation and the maintenance are inconvenient. The utility model is widely applied in the power sector, the building material sector, the chemical industry and other sectors.
Description
(1) technical field:
The utility model relates to industrial milling equipment, particularly is applied to a kind of high-efficiency and energy-saving type fan coal mill in the industries such as electric power, building materials, chemical industry.
(2) background technology:
Existing domesticly introduce German KSG type fan coal mill the earliest and use so far always, this coal mill includes a support, motor, bearing block are housed on the support, power transmission shaft is housed on the bearing block, power transmission shaft connects with motor by shaft coupling, end at support is equipped with fan mill body, fan mill body includes casing, is furnished with interior lining panel on the inner peripheral surface of casing, and impeller is housed in the casing, shock plate is housed, impeller and propeller shaft couplings on impeller.Shock plate in this coal mill is optic panel (and material is very not wear-resisting 13Mn high manganese steel), shock plate is the mode that the card ear is adopted on both sides with connecting of impeller, therefore this coal coal-grinding powder outlet is inhomogeneous, fineness deficiency (outlet fineness 80 orders account for total output about 80%), the wearability of shock plate is not enough, change more frequently, it is complicated that structure seems, installation, maintenance inconvenience.On the other hand, the interior lining panel of this coal mill is to be inlayed by tens fritter liner plates to form, and material is a grey cast-iron, so the dismounting inconvenience of interior lining panel, wearing and tearing easily, and installation, maintenance are complicated especially and time-consuming, operating efficiency is low.
(3) summary of the invention:
The purpose of this utility model be to overcome import coal mill, discharge is inhomogeneous, fineness deficiency, and complex structure, problems such as consumable accessory anti-wear performance difference provide a kind of high-efficiency and energy-saving type fan coal mill.
Concrete scheme of the present utility model is: improve at existing inlet fan coal mill, it has the basic structure of inlet fan coal mill, it is characterized in that: be contained in the shock plate on the impeller, design has some boss on its relative material shock surface.
Boss on the described shock plate is that precious nail semicircle is spherical.
Be simplified structure, improve the anti-wear performance of shock plate, shock plate and impeller are to adopt easy Bolt Connection in the utility model, and shock plate is to adopt high-strength wearable Cr26 alloy cast steel to make.
To be arranged in the utility model simultaneously on the casing inner peripheral surface interior lining panel by polylith change into by " a 7 " type interior lining panel, three arc interior lining panels and block length side's interior lining panel totally five bulks form, and change the material of interior lining panel into the high-chromium alloy abrasion resistant cast steel by grey cast-iron and make, and adopt screw and casing to be connected and installed.
After improving, the utility model obtained following effect:
1. the outlet fineness of pulverized coal is thinner, reaches more than 80 orders, accounts for more than 90% of the total degree of outlet, and the ratio that accounts for total output significantly increases, and has improved grinding machine ratio of reduction efficient and performance simultaneously.
2. designs simplification reduces cost, and makes things convenient for installation, maintenance.
3. prolonged the service life of shock plate, almost reached than former design and be enhanced about more than once service life.
4. prolonged the service life of grinding machine interior lining panel, improved production efficiency, shortened the replacing operating time of grinding machine interior lining panel simultaneously, given processing, a large amount of fund of having saved is installed.
(4) description of drawings:
Fig. 1 is a general structure front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the side view of shock plate;
Fig. 4 is the segmentation schematic diagram of the utility model interior lining panel.
Among the figure: 1-casing, 2-charging aperture, 3-discharging opening, the 4-shock plate, 5-screw, 6-impeller, the 7-power transmission shaft, 8-bearing block, 9-shaft coupling, the 10-motor, 11-support, 12-fan mill body, 13-" 7 " type interior lining panel, 14,15,16-arc interior lining panel, the 17-screw, the rectangular interior lining panel of 18-, 19-semi-round ball boss.
(5) specific embodiment:
Referring to Fig. 1, Fig. 2, the utlity model has the basic structure of conventional fan grinding machine, include a support 11, motor 10 and bearing block 8 are housed on the support 11, power transmission shaft 7 is housed on the bearing block 8, and power transmission shaft 7 one ends connect (other end connects with impeller 6) by shaft coupling 9 with motor 10.Left end at support 11 is equipped with fan mill body 12.Fan mill body 12 includes casing 1, and casing 1 is provided with charging aperture 2 and discharging opening 3, is furnished with interior lining panel on the inner peripheral surface of casing 1, and impeller 6 is housed in the casing 1, and shock plate 4 is housed on impeller 6, and impeller 6 connects with power transmission shaft 7.Improvement of the present utility model is: shock plate 4 is to adopt Cr 26 alloy cast steels to make (also can take other high-abrasive material makes), and particularly design has the precious nail spherical boss 19 of semicircle (referring to Fig. 3) on relative material shock surface on the shock plate 4.Boss 19 also can be made into different shapes such as cylindric, arc convex.Shock plate 4 is to adopt screw 5 to connect assembling with impeller 6.Interior lining panel in the utility model fan mill body 12 is formed (referring to Fig. 4) by five bulks, include " a 7 " type interior lining panel 13 and three arc interior lining panels 14,15,16, and block length side's interior lining panel 18, and five interior lining panels adopt the high-chromium alloy abrasion resistant cast steel to make (as the Cr15 steel alloy), adopt screw 17 that five interior lining panels are fixedly mounted on and promptly constitute the utility model in the casing 1.
