Abstract
The utility model discloses a dust falling screen board used for a coal yard. The dust falling screen board used for the coal yard comprises a body with the V-shaped cross section, the bending position of the body is in transition through a bending face, a plurality of round holes I are formed in the bending face in the extending direction of the bending face, splicing planes are arranged on the two sides of the body, a plurality of oval holes are formed in the splicing planes in the length directions of the splicing planes, and a plurality of round holes II are evenly formed among the bending faces and the splicing planes. Due to the design of the V-shaped board body and open holes with different shapes and hole diameters, raised dust in the coal yard is reduced, air quality is improved, pollutant discharge requirements of the national environmental laws and regulations are met, and meanwhile storage cost is reduced.
Description
Technical field
The utility model belongs to the dust guard technical field, relates to a kind of depositing dust web plate for coal yard.
Background technology
At present, the heap material extracting operation is the open-air open type operation of continuity in coal yard, in operation technology and operating environment with and the influence of bulk cargo self-condition, can produce a large amount of airborne dusts, meet strong wind weather and easily produce reentrainment of dust, surrounding environment is polluted, also caused a certain amount of material loss.
Summary of the invention
The purpose of this utility model provides a kind of depositing dust web plate for coal yard, has solved that a large amount of airborne dusts that the operation of present coal yard open type causes pollute environment and the problem of material loss.
The technical scheme that the utility model adopts is, a kind of depositing dust web plate for coal yard, comprise that cross section is the body of V-arrangement, the bending place of body is by the bending side transition, bending side is provided with some circular hole I along its prolonging direction, the body both sides are provided with the splicing plane, and its length of splicing upper edge, plane evenly is provided with some circular hole II to being provided with some elliptical apertures between the bending side on the body and the splicing plane.
The beneficial effects of the utility model are that by the design of V shaped slab body and the perforate in difformity and aperture, minimizing coal yard airborne dust improves air quality, satisfies the requirement of national environmental protection laws and regulations and pollutant emission, reduces the storing cost simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of depositing dust web plate for coal yard of the utility model.
Among the figure, 1. body, 2. circular hole I, 3. bending side, 4. circular hole II, 5. splicing plane, 6. elliptical aperture.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model provides a kind of depositing dust web plate for coal yard, as shown in Figure 1, comprise that cross section is the body 1 of V-arrangement, the bending place of body 1 is by bending side 3 transition, bending side 3 is provided with some circular hole I2 along its prolonging direction, body 1 both sides are provided with splicing plane 5, and its length of splicing 5 upper edges, plane evenly is provided with some circular hole II4 to being provided with some elliptical apertures 6 between the bending side 3 on the body 1 and the splicing plane 5.
Depositing dust web plate of the present utility model is according to aerodynamic principle, and when wind passed through the depositing dust web plate, separating and adhering to two kinds of phenomenons appearred in depositing dust web plate back, forms upper and lower disturbing flow, reduces the wind speed of incoming flow wind, loses the kinetic energy of incoming flow wind greatly; Reduce the turbulivity of wind, eliminate the eddy current of incoming flow wind; Reduce shear stress and the pressure on dump surface, play the dirt rate thereby reduce stockpile.Simultaneously, for the floating dust that forms owing to handling operation, the depositing dust web plate by the setting of non-dominant wind direction is stopped, reaches desirable anti-dust effect.
For the depositing dust plate of general non-perforate, when the ambient atmosphere wind speed flows through, to continue to occur the separation of air-flow on the top of depositing dust plate, form the large scale separation vortex suitable with depositing dust plate hight yardstick, and the warp (being called again attached) earthward in the wall downstream, the separation vortex of this large scale has bigger coiling energy, has the purpose that does not only reach wind-screening dust-suppressing under the situation of sand drift, dust heap in the downstream, the husky ability of taking of air-flow is increased, play the dirt rate and strengthen.
Combine for the monolithic polymer matrix composites deep bead of depositing dust web plate of the present utility model by V-arrangement, each monolithic presses down distributed on the aerofoil different passes, different aperture and different percent openings, percent opening 28～32%.Different cross section and percent opening thereof press down aerofoil because cross sectional shape, aperture are different with percent opening, the local flow that forms is very inequality, wherein in aperture, local high velocity, local low regime and local little whirlpool have been formed with the downstream, the regional and vortex generation mutual interference mutually of the local high, low speed that different cross sectional shapes makes above-mentioned local flow form.Thereby consumed the energy of high speed incoming flow, undersized vortex is decayed rapidly, make downstream airflow mean kinetic energy and take the dirt ability and greatly reduce.
