Abstract
The utility model discloses a spiral lump coal feeder which is a chute descending spirally, wherein the bottom edge of the cross section of the chute takes the shape of a straight line; the outer edge of the cross section of the chute is a straight line extending upwards; and the edge on the inner side of the chute is an open circular arc-shaped central overflow port. As the lump coal in the spiral lump coal feeder declines slowly, and coal power at the periphery of the lump coal performs a slight buffering deceleration function, the abrasion on the bottom surface of the chute is lower, and the spiral lump coal feeder can be used for more than 3 years in a coal washing plant capable of producing 4,000,000 ton washed coal per year.
Description
Technical field
The utility model relates to a kind of spiral lump coal feeder, and this feeder is used for outwards carrying lump coal from coal bunker.
Background technology
The installation of the screw of the lump coal feeder that prior art adopts is complex-shaped, and is repeatable poor: processing, construction period are long, and it is many that material is assisted in installation; A large amount of use costs of artificial mechanism etc. are high; Slight errors in design, the installation process is prone to take place blanking, putty fault midway, and extremely difficult remedial reparation.
Summary of the invention
The utility model technical matters to be solved be install complex-shaped, repeatable poor: processing, construction period are long, and it is many that material is assisted in installation; A large amount of use costs of artificial mechanism etc. are high; Design, the slight errors in the installation process are prone to take place blanking, putty fault midway, and problem such as extremely difficult remedial reparation.
In order to solve the problems of the technologies described above; The utility model provides a kind of spiral lump coal feeder; This spiral lump coal feeder is the chute that a spiral descends; The base of the chute cross-sectional plane that said spiral descends is a linear, and the outer of this chute cross-sectional plane is for extending upward straight line, and the inner side edge edge of this chute is a unscreened circular arc center overflow leak.
As a kind of preferred version, the rotating diameter of the chute that said spiral descends is 850 ~ 1050mm.
The beneficial effect of the utility model is:
1. speed was slow when the lump coal in the utility model spiral lump coal feeder was owing to decline, and was with slight smalls buffer deceleration outward, so less to the loss of chute bottom surface, year production 4,000,000 tons of washery life-spans of coal washing should be greater than 3 years.
2. the utility model spiral lump coal feeder equipment package set-up time lacks, and does not stop production to take storehouse of completion in 8-15 days under the production time situation.
3. the spiral chute of the utility model is owing to can adopt modularization production, and general interchangeability is good, and the entrance damage only need be changed 90 degree unit and get final product, and changes work-hours less than 16 hours, is easy to modular repair and changes.
4. the utility model spiral lump coal feeder can reduce the lump coal fragmentation of putting in storage, and lift block carbon rate should be best anti-crushing device at present.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of spiral chute in the utility model spiral lump coal feeder.
Fig. 2 is the installing condition figure of the utility model spiral lump coal feeder in empty coal bunker.
Fig. 3 is the running condition figure of the utility model spiral lump coal feeder in coal bunker.
The Reference numeral note:
1 chute outer edge; 2 chute slideway bottom surfaces; 3 center overflow leak; 4 lump coal storehouses; 5 main spiral chutes; 6 secondary spiral chutes; 7 lump coal.
The specific embodiment
As shown in Figure 1; The spiral lump coal feeder that the utility model provides is the chute that a spiral descends; The chute that said spiral descends is made up of chute slideway bottom surface 2, chute outer edge 1 and center overflow leak 3; The base of the chute cross-sectional plane that this spiral descends is a linear, and the outer of this chute cross-sectional plane is for extending upward straight line, and the inner side edge edge of this chute is a unscreened circular arc center overflow leak 3; The rotating diameter of the chute that said spiral descends is 850 ~ 1050mm.
As shown in Figures 2 and 3; The spiral lump coal feeder that the utility model provides is installed in the lump coal storehouse 4; A main spiral chute 5 is installed in left side in lump coal storehouse 4, on the right side in this lump coal storehouse 4 a secondary spiral chute 6 is installed, and main spiral chute 5 drives lump coal 7 and upwards transports.
The concrete use of the utility model is described below:
The utility model spiral chute adopts the casting of manganese steel segmented precise, and thickness can suitably increase, and to increase the intensity and the service life of spiral chute, spiral angle is established by NC-machining, and the consistent accurate errorless ability of this angle guarantees good operational effect.Again spiral chute is welded to connect into 2.4 meters one section, the dark 15 meters coal bunker in storehouse only needs about 6 sections and gets final product.Whole vertical chute is installed in by the coal bunker wall, and 12 fulcrums of 360 degree pass the bulkhead bolt by round steel, and steel plate reinforcement is welded, and can guarantee the sorrow that firm nothing collapses.
After the spiral chute installation of lump coal storehouse, because the physical construction of helical angle is limit, the vertical maximum drop of lump coal (not having initial velocity basically) solves the broken problem of bump of lump coal less than 750 millimeters.Because mechanical tilt designing institute limit, no putty reaches blanking accident midway in the chute.
Reduce the storage capacity problem for solving single coal breakage point, increase can be used capacity, its belt midway or storehouse coal breakage opposition point 6 meters secondary chutes are installed, diffuse into the actual usage space of storage.
The protection domain of the utility model is not limited to above-mentioned embodiment, and every conspicuous technology distortion of being done according to the utility model know-why all falls within the protection domain of the utility model.
