Abstract
The utility model discloses a kind of transmitting bulk material head based on DEM design system of gathering materials, comprise belt, head cylinder, head funnel and head cover, the conveying end of described belt is connected with described head cylinder, described head funnel is arranged on described head cylinder below, described head cover is arranged on described head funnel top, system also comprises that one is circular-arc head aggregate bin and aggregate bin angular adjustment bar, and described head aggregate bin is arranged in described head funnel and is fixed on described permanent seat by strut bar; Adopt the aggregate bin of convex structure, the material entering from belt is to wash away bucket wall and be not to clash into, little to aggregate bin damage, and material is along bucket wall whereabouts, can suppress airborne dust by actv., reduces potential safety hazard, the smooth and easy putty phenomenon that there will not be of material operation, production efficiency is high.
Description
Technical field
The utility model relates to a kind of bulk transport system, relates in particular to a kind of head aggregate bin system of the transmitting bulk material based on DEM design.
Background technology
In bulk transport system, particularly carry in the system of coal charge, its head funnel is to be all generally designed to controllable register, adjust the running orbit of material by controllable register, material can produce certain dust in the time clashing into controllable register, moreover, the material shape that scatters falls down, this also can produce very large dust, material free-falling body falling speed is fast and form negative pressure, material will mix with air, the material of mixing air is fallen can squeeze out again air on belt, take more substantial dust out of, airborne dust is very serious, make the severe of surrounding environment change, dust easily fires, there is larger potential safety hazard, easily there is putty phenomenon simultaneously, affect the normal production of equipment, production efficiency is low, and large to equipment damage, virtually increase use cost.
The technical problems to be solved in the utility model is to provide and is not a kind ofly prone to dust, without potential safety hazard, be difficult for the head aggregate bin system of putty.
Utility model content
The problems such as above-mentioned prior art airborne dust is serious in order to solve, potential safety hazard is large, easily putty, production efficiency be low, the utility model adopts following technical scheme:
The utility model provides a kind of transmitting bulk material head based on DEM design system of gathering materials, comprise belt, head cylinder, head funnel and head cover, the conveying end of described belt is connected with described head cylinder, described head funnel is arranged on described head cylinder below, described head cover is arranged on described head funnel top, system also comprises that one is circular-arc head aggregate bin and aggregate bin angular adjustment bar, and described head aggregate bin is arranged in described head funnel and is fixed on described permanent seat by strut bar.
As to improvement of the present utility model, described head aggregate bin and material transferring angular separation are 20 °.
As to further improvement of the utility model, described head aggregate bin also comprises liner.
As to further improvement of the utility model, described liner is wear-resistant ceramic brick or wear-resisting steel plate.
The beneficial effects of the utility model are: the aggregate bin that adopts convex structure, the material entering from belt be wash away bucket wall and be not clash into, little to aggregate bin damage, and material falls along bucket wall, can suppress airborne dust by actv., reduce potential safety hazard, the smooth and easy putty phenomenon that there will not be of material operation, production efficiency is high.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation that does not add head cover in the utility model.
Fig. 3 is the structural representation that does not add head cover and head funnel in the utility model.
Detailed description of the invention
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of transmitting bulk material head based on DEM design system of gathering materials, comprise belt 1, head cylinder 2, head funnel 3 and head cover 4, the conveying end of described belt 1 is connected with described head cylinder 2, described head funnel 3 is arranged on described head cylinder 2 belows, described head cover 4 is arranged on described head funnel 3 tops, system also comprises that one is circular-arc head aggregate bin 5 and aggregate bin angular adjustment bar 6, regulate the opening angle of head aggregate bin 5 by aggregate bin angular adjustment bar 6, meet any operating needs, use more convenient simple and direct, described head aggregate bin 5 is arranged in described head funnel 3 and is fixed on described permanent seat 7 by strut bar 71, the material entering from belt 1 is through head cylinder 2 inflow equipment, because head aggregate bin 5 is circular-arc, after material enters, be to wash away material wall and not clash into, so both can reduce the damage of material impacting to equipment, also reduce the appearance of dust simultaneously, have again, material enters into head funnel along bucket wall, and be not that direct free-falling body drops, so also can further reduce dust occurs, can reduce dust and fire the potential safety hazard of bringing simultaneously.
In the utility model, described head aggregate bin 5 is 20 ° with material transferring angular separation, and in fact in production process, requiring this angle is to be less than 20 °, is write for convenience as 20 °, material just clashes into bucket wall to be less than 20 degree angles like this, little to hopper damage.
In the utility model, described head aggregate bin 5 also comprises liner 51, described in, 51 is wear-resistant ceramic brick or wear-resisting steel plate, liner can further reduce the impact of material to head aggregate bin, reduce equipment loss, reduced use cost.
The above-mentioned DEM mentioning is necessary its detailed description, DEM is also referred to as distinct element method, so-called distinct element method is for discontinuous medium, for example ground, mineral, vegetable seeds, chemical fertilizer, food etc., for studying its mechanical property, engineering properties and the power of branch and the characteristic of motion during with other object contacts, a kind of scientific experiment analysis method based on computer modeling technique rising for ease of experiment Analysis, the general solution procedure of distinct element method is: discrete bodies is reduced to the set of definite shape and quality particle, give between contact particle and stressed between particle and engagement edge, speed, the parameter of acceleration/accel etc., and adjacent Unit two are coupled together with rational Connection Element according to practical problems.Between unit, relative displacement is basic variable, can obtain normal direction and tangential application force between Unit two by the relation of power and relative displacement, outside application force to unit in all directions and between other unit and other physical field are caused to unit effect, make every effort to make a concerted effort and resultant moment, can be in the hope of the acceleration/accel of unit according to newton second law of motion, it is carried out to time integral, and then obtain speed and the displacement of unit.Thereby obtain the physical quantitys such as all unit speed, acceleration/accel, cireular frequency, displacement of the lines and corner at any time.This method is particularly suitable for solving non-linear problem.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
