A kind of blanking device for suppressing eminence blanking airborne dust
Technical field
This utility model is related to material transportation art, more particularly to a kind of blanking device for suppressing eminence blanking airborne dust.
Background technology
Cement industry is related to the discharging of a large amount of granular materials and windrow, needs to consider that material is passing through during windrow
Suppress airborne dust during blanking after rubber conveyer lifting.With environmental requirement more and more higher, granular material is in discharging and windrow process
In suppression airborne dust measure be also increasingly necessary, while must also reach simple structure, the requirement of cost economy.
In actual production process, the traditional open stockyard cutting mode for using at present, due to blanking higher, the thing of height
Material is in blanking process, because wind resistance produces larger drift dirt, while material falls on the loading end of stockyard, can also produce greatly
Airborne dust.This technical problem can be solved in prior art using flexible blanking sleeve, but due to flexible blanking sleeve
Itself is heavier, causes belt haulage head pulley Platform Designing load to increase, and expense is dramatically increased.Meanwhile, the blanking sleeve that stretches is needed
Being equipped with height of materials induction apparatuss and blanking grease head highness being lifted to control hoist engine, required electric component further increases invests into
This.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, with reference to embodiment, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used for explaining that this practicality is new
Type, is not used to limit this utility model.
Fig. 1 is according to the schematic diagram for suppressing the blanking device of eminence blanking airborne dust of the present utility model.As illustrated,
The blanking device generally includes 200 two parts of blanking scraper-trough conveyer 100 and adhesive tape conveyer for being vertically arranged at loading end more than 300.
Wherein blanking scraper-trough conveyer 100 includes the scraper-trough conveyer main body 120 of the pedestal 110 and cuboid being fixed on loading end 300, wherein slipping
Sub- main body 120 is hollow structure, and the cavity for being used to accommodating material is contained in its inside, and scraper-trough conveyer main body 120 is vertically provided at
On pedestal 110, it is beneficial to material and falls in cavity from the top of scraper-trough conveyer main body 120.Multiple material leakages are offered in scraper-trough conveyer main body 120

Fig. 4 a and 4b show the side view of material spilling hole 121 and turnover panel gate valve 122 under different conditions.When not by any outer
Power or when being only subject to thrust from outside to inside, turnover panel gate valve 122 keeps the closure state shown in Fig. 4 a;When by from inside to outside
During thrust, turnover panel gate valve 122 is then converted into the unlatching turntable shown in Fig. 4 b.
Fig. 5 a and Fig. 5 b show the working condition of blanking device.Wherein, as shown in Figure 5 a, before new one layer of material falls
The material of stockyard peak has been positioned at second 121 ' place of material spilling hole in scraper-trough conveyer main body 120 from bottom to top.With material not
Disconnected to fall from the top of scraper-trough conveyer main body 120, the material in cavity gradually increases, when material is increased to above material-dropping hole 121 '
Material-dropping hole 121 " place when, the Horizontal Tension of material itself is material-dropping hole 121 " the turnover panel gate valve 122 at place provides from inside to outside
Thrust, so that the turnover panel gate valve 122 is opened, material is automatically from material-dropping hole 121 " flow out, and heap is flowed to by action of gravity therewith
The bottom of field 400.As shown in Figure 5 b, new one layer of stockyard 410 will be formed on 400 surface of stockyard when material is enough, and will
Material-dropping hole 121 " is filled in stockyard 400.When the material for having renewal again falls, then can repeat said process.With stockyard 400
Interior level of filler material is raised step by step, and the layering of turnover panel gate valve 122 of each layer is opened, and material flows out.
Preferably, can be in scraper-trough conveyer main body 120 --- particularly in the position of middle and upper part --- a rapping electricity be set
Machine (not shown), to prevent feed blocking material-dropping hole 121 to be piled up in cavity, it is ensured that material can establish discharge.
Compared with the blanking device of prior art, blanking device of the present utility model blanking device of the present utility model is adopted
The mode of layering blanking so that no matter any height dropping material can ensure by material landing relative altitude be limited in 1 meter with
It is interior, effectively reduce the probability of airborne dust;Also strengthen the mobility of material in addition by arranging electric motor of shaker, effectively prevent stifled
Plug.
