Abstract
The invention discloses a dust-free loading pipe, comprising a hopper (4) and an upper cover plate (2) covering a hopper opening. The top surface of the upper cover plate (2) is connected with a feed pipe (1). The bottom of the hopper (4) is connected with a bleeder valve. The dust-free loading pipe also comprises a hand wheel (5) on the feed pipe (1), a lead screw (6) passing through the feed pipe (1) and entering the hopper (4), a fixing frame (7) connected with the inner wall of the hopper (4) and coupled with the lead screw (6), and a pipe core (6) connected with the bottom of the lead screw (6). The lead screw (6) is coaxial with the hopper (4), and a uniform annular gap is formed between a pipe core working segment (9) on the lower part of the pipe core (6) and the inner wall of the hopper (4). Particle materials pass through the annular gap, and then form a hollow particle material column, the hollow particle material column drops with gravity, and drives air inside to move, and generates Bernoulli effect, dusts are absorbed in air flow in the material column in the vacuum state, so as to achieve dust-free loading effect.
Description
Technical field
The present invention relates to a kind of dustless loading pipe, be applicable to the dustless granting of graininess bulk cargo, belong to material transport system technical field.
Background technology
At present, loading pipe is the significant element of loose mass transport delivery system, is widely used in harbour, harbour, large-scale bulk granular material are stored up, in processing enterprise.But, because loose material contains dust granules, in granting, entrucking, shipment process, often evoke many flying dust dust, so not only cause the instability that material is provided, the job requirements that some environmental demands is high can't be met.For avoiding environmental pollution, usually only by reprint pipe be not all right, dust collector must be increased in distribution process and solve the problems referred to above, this adds increased extra investment and energy resource consumption, also improve the cost of operation simultaneously.Thus if develop and eliminate the loading pipe be permeated with of dust, will be a simple scheme.
Summary of the invention
For above-mentioned existing technical matters, the invention provides a kind of dustless loading pipe, raise excessive, for loose material transport system provides stable supplied materials for the dust eliminated when bulk cargo loads.
For achieving the above object, the invention provides a kind of dustless loadings and manage, comprise hopper and cover the upper cover plate of its quarrel, this upper cover plate end face is connected with feed pipe, and this feed hopper bottom is connected with bleeder valve; Also comprise the handwheel be positioned at above feed pipe, run through feed pipe and enter leading screw in hopper, connect hopper inwall and be set with the fixed mount of screw mandrel, and the tube core bottom connection wire rod.Wherein: this tube core is coaxial with hopper, and form uniform circular clearance between the tube core active section and hopper inwall of tube core bottom, and regulate the width in this gap by handwheel and leading screw.
Bulk granular material is by behind the circular clearance between hopper and tube core, and the bulk cargo post forming hollow draws off, and the bulk cargo post of hollow declines under gravity, and drives air wherein to produce Bernoulli effect thereupon moving: namely the flow velocity of fluid is larger, and pressure is less; The flow velocity of fluid is less, and pressure is larger, and dust is inhaled into the air stream in the stock column in vacuum state, reaches dustless loading effect.
Further, coniform with straight section of the described preferred top of hopper shape, the shape preferably coniform shape be formed by connecting up and down with frustum of tube core, and the tube core active section of frustum has identical cone angle with hopper conical section, realize the circular clearance between tube core active section and hopper inwall with this, and this annular gap width is a fixed value.
Further, the width of described circular clearance is 20-25mm.
Further, described bleeder valve adopts gate valve.
Further, described hopper outer wall is evenly equipped with hanger.
The delivery system that dustless loading Guan Keyu of the present invention can obtain stable supplied materials is connected, such as: conveyer system, vertical silo deliver from godown, bulkhead delivery system, automobile/train loading system etc.Open feed hopper bottom gate valve, when providing bulk cargo, bulk cargo should maintain certain height in hopper, can obtain stable hollow bulk cargo post when dustless loading pipe is worked always, the supplied materials that the material delivery system that can all fall apart provides stable, makes material can enter in hopper with stable rate.Compared to prior art, there is environmental protection and stablize, simple, the advantage that cost is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, the present invention includes hopper 4 and cover the upper cover plate 2 of its quarrel, be distributed in the hanger 3 of hopper 4 outer wall, connect the gate valve at hopper 4 bottom discharge mouth place, connect the feed pipe 1 of upper cover plate 2 end face, be positioned at the handwheel 5 above feed pipe 1, run through feed pipe 1 and enter leading screw 6 in hopper 4, connect hopper 4 inwall and be set with the fixed mount 7 of screw mandrel 6, and the tube core 6 bottom connection wire rod 6.
Wherein, tube core 6 is placed in hopper 4, and extends to discharge outlet, and both are in coaxial state, and the tube core active section 9 of tube core 6 mainly its underpart, position of playing effect, form circular clearance between this section and hopper 4 inwall.The graininess material that falls apart enters after in hopper 4 from feed pipe 1, can enter under gravity in the circular clearance that hopper 4 and tube core active section 9 formed, thus formation hollow bulk cargo post.
As Figure 2-Figure 5, for guaranteeing that material is by forming stable hollow bulk cargo post behind the circular clearance between hopper 4 and tube core active section 9, hopper 4 shape is preferably with the cone shape of straight section, and the shape that tube core 6 shape is preferably made up of up and down coniform and frustum, then hopper 4 bottom has identical cone angle with the tube core active section 9 of frustum, then the even width of circular clearance is fixed.Further, this gap can utilize handwheel 5 and leading screw 6 to set before the loose material of conveying, about 20-25mm, or according to being transferred the setting such as kind, flowing velocity of material.
During use, gate valve at the beginning below hopper 4 is cut out, to enter in hopper 4 and after piling up certain height from feed pipe 1 until material, open gate valve, owing to defining uniform circular clearance between hopper 4 and tube core active section 9, bulk granular material is by behind the circular clearance of this fixed value, form the bulk cargo post of hollow, this hollow bulk cargo post declines with gravity, and drive air wherein to produce Bernoulli effect thereupon moving, dust is inhaled into the air stream in the stock column in vacuum state, reaches dustless loading effect.In addition, when providing bulk cargo, bulk cargo should maintain certain height in hopper 4, obtains stable hollow bulk cargo post when dustless loading pipe just can be made to work always.
