Description

Solid material homogeneous flow control storehouse
Technical field
The utility model relates to cement industry production equipment technical field.
Background technology
In cement industry production process, repeatedly process material, feed bin uses in a large number in material processing procedure.The upstream device of general feed bin all there are certain requirements the uniformity of feed bin discharging character, and the character of discharging all neat degree is high, and operating efficiency, operation stability and the service behaviour of upstream device can improve, and can greatly reduce the fault rate of upstream device.
Feed bin is widely used in cement production process, its to the homogeneous effect of material according to use location difference the influence degree difference to production process.Such as, roll squeezer is just being widely used in the raw grinding and cement pulverizing course in manufacture of cement as a kind of energy-efficient equipment, and is the normal steadily safe operation that ensures roll squeezer, and the feeding of keep continuously, stablizing, homogenize is vital.Up to the present, the steady material measure generally adopting in industry is to add a feed bin on roll squeezer spout top, and bunker capacity is about 30 ~ 50 tons of left and right; The shape in storehouse has circular cone and side to bore two kinds.Retransmit sensor control headend equipment feeding capacity by storehouse and keep having in storehouse certain stable inventory, thereby ensure that the material of feeding roller press has a metastable material to press and discharging quantity.
Prior art is shown in accompanying drawing 1:
Taking the front end feed trap of roll squeezer as example, it is a simple inventory control storehouse, there is a cylinder 1, the bottom of cylinder 1 is reverse taper 11, the bottom setting tool of controlling storehouse has the discharging opening 12 of control panel, control the top in storehouse and establish charging aperture 10, prior art has just simply considered that will meet a certain amount of inventory maintains stable feeding capacity to roll squeezer and certain feeding pressure, and do not consider that the material that is fed into roll squeezer is all the compound that various materials is worked good, because of in storehouse without any material flow path direction control device, these compounds can be because of the body difference in storehouse, the difference of unit weight and particle diameter and fluidity, be subject to feedstock direction, charging rate, the impact of charging drop, chemical property and the physical property skewness of the material that can cause storage in feed bin, particularly can cause in storehouse material feeding roller press entrance time, its material is in the axial location inequality of roll surface of roller press, cause roll gap between the two rollers of roll squeezer, stressed, wearing and tearing are uneven, thereby can cause roll squeezer pressing effect greatly to reduce, equipment operational shock strengthens, roll surface minimizing in service life, complete machine maintenance increases.
The shortcoming of prior art: prior art just ensures that material keeps the current stabilization storehouse of certain flow, easily produces segregation, the sub-prime phenomenon of compound in use procedure, has strengthened feeding at position and qualitative nonunf ormity.

Detailed description of the invention
With embodiment, the utility model is further described below:
With reference to figure 2, Fig. 3 and Fig. 4, the utility model proposes a kind of solid material homogeneous flow control storehouse, it comprises feeding bin, and the main body of feeding bin is that diameter is that 3m, height are the cylinder 1 of 5 m, and the bottom of feeding bin is back taper portion 11, and back taper portion 11 has discharge port 12.
In feeding bin, central authorities vertically establish a cylindrical shape material flow path direction control device, this material flow path direction control device has a straight barrel 2, the diameter of straight barrel 2 is 1000mm, be that circumference L is 3140 mm, high h is 4510 mm, straight barrel 2 several rectangle material mouths 22 that are interspersed from top to bottom, the height h3 of each rectangle material mouth 22 is 300 mm, transverse arc length L 1 is 500mm.
Rectangle material mouth 22 lateral circumferential on the straight barrel 2 of the present embodiment are placed side by side composition material mouthful row, every group of material mouth arranged uniform 4 rectangle material mouths 22, adjacent rectangle material mouth 22 L2 of being laterally separated by is 285mm, it is 320mm that adjacent material mouth is arranged the h2 of being separated by, adjacent material mouth row's rectangle material mouth 22 misplaces alternate, arranges altogether 7 discharge gate rows.
Rectangle material mouth 22 is topmost 370 mm from straight barrel upper port distance h 4, rectangle material mouth 22 is bottom 120 mm from straight barrel lower port distance h 1, the gross area of rectangle material mouth 22 accounts for the straight barrel gross area 60%, the back taper portion 11 of feeding bin is fixed in the lower end of straight barrel 2, the upper shed central authorities of feeding bin are fixed in the upper end of straight barrel 2 by bracing frame 13, the upper port of straight barrel 2 is charging aperture 21.In the present embodiment, the end of the interior nearly back taper of straight barrel 2 portion 11 is provided with tapered cap 4, and the bottom surface diameter of tapered cap 4 is i.e. 500 mm of 1/2(of straight barrel 2 diameters), tapered cap 4 is fixed on the nearly lower end central authorities of straight barrel 2 by bracing frame 41.
After compound is fed by rubber conveyer, material to sinking under storehouse when also with horizontal direction speed, heterogeneity material is due to sealing-tape machine position, place difference, the momentum of material self varies in size, phase mutual interference in motion process between material with in horizontal movement direction apart from discharging homogeneous device apart from different and contact the difference of discharging homogeneous device position, these factors can make material produce downward sedimentation and horizontal motion, change nyctitropic motion with the collision of discharging homogeneous device, after being deposited between discharging homogeneous device and bulkhead diverse location or running into bulkhead by material channel on discharging homogeneous device, change the direction of motion, the material sinking in discharging homogeneous device, according to different angle of repose, material self the momentum sizes of flowing of material, the difference of the inside and outside solid accumulation height of the character such as different profiles and discharging homogeneous device and position, can stay the diverse location in discharging homogeneous device or flow to the diverse location between discharging homogeneous device and feed bin, make material pile up with discharge process in the direction of motion and discharging after present position be effectively controlled, thereby little storehouse material can evenly be drawn off.
