Abstract

The utility model discloses a kind of structure reducing the wearing and tearing of elephant trunk pipe bent position, comprise supply pipe and the discharge nozzle of elephant trunk, supply pipe and discharge nozzle shape have angle, the inclination angle of supply pipe is less than the inclination angle of discharge nozzle, in the life of prolonging of supply pipe tail end, storing pipe is set, the utility model utilizes the self structure of existing elephant trunk, by the flow direction of the mode flip-flop material of shock, make while reduction material speed, greatly reduce the friction of material to elephant trunk, because the material having piled up the flowing that material is also at shock place decreases the contact with elephant trunk, realize the premature abrasion of anti-fluid stopping pipe bend, the utility model theory and structure is simple, easy to make, with low cost, be applicable to marketing.

Description

A kind of structure reducing the wearing and tearing of elephant trunk pipe bent position

Technical field

The utility model relates to a kind of structure reducing the wearing and tearing of elephant trunk pipe bent position, belongs to grain processing equipment technical field.

Background technique

Carry out from slipping in course of conveying at material, the serious position of pipe wear is the place that is hit of pipeline often, this is because when shaggy grain grain material is with this section tubular wall of velocity shock faster, tube wall surface generation wear-out failure, erosion together with this wearing and tearing combine with fatigue wear, make tube wall comparatively fast thinning, and even it is worn out, a large amount of waste and factory cost is caused to increase, adopt in prior art and baffle plate or the larger object of friction factor are set in corner to realize the reduction of material speed, so this scheme is also very undesirable, first material first time with when baffle plate or the larger object contact of friction factor be still fretting wear, although reduce material speed, but also considerably increase the possibility containing baffle plate impurity or material particles in material, make the grain quality that processes low.

Summary of the invention

The purpose of this utility model is: provide a kind of structure reducing the wearing and tearing of elephant trunk pipe bent position, can greatly reduce the wearing and tearing of elephant trunk pipe bent position, to overcome the deficiencies in the prior art.

The technical solution of the utility model

Reduce a structure for elephant trunk pipe bent position wearing and tearing, comprise supply pipe and the discharge nozzle of elephant trunk, supply pipe and discharge nozzle shape have angle, and the inclination angle of supply pipe is less than the inclination angle of discharge nozzle.

Before a kind ofly reduce in the structure of elephant trunk pipe bent position wearing and tearing, prolonging of supply pipe tail end raw storing pipe is set, arranges at storing pipe place and renovate.

Before a kind of reduce elephant trunk pipe bent position wearing and tearing structure in, the length of described storing pipe is 100-500mm.

Owing to have employed technique scheme, compared with prior art, the utility model utilizes the self structure of existing elephant trunk, by the flow direction of the mode flip-flop material of shock, make while reduction material speed, greatly reduce the friction of material to elephant trunk, because the material having piled up the flowing that material is also at shock place decreases the contact with elephant trunk, realize the premature abrasion of anti-fluid stopping pipe bend, the utility model theory and structure is simple, easy to make, with low cost, be applicable to marketing.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described in detail, but not as to any restriction of the present utility model.

Embodiment of the present utility model: a kind of method reducing the wearing and tearing of elephant trunk pipe bent position, the method utilizes this body structure of elephant trunk, utilize clash into mode to change the flow direction of material, thus realize be reduced in elephant trunk pipe bent position material gliding speed or minimizing material reduce the wearing and tearing of material to elephant trunk pipe bent position in the contact of elephant trunk pipe bent position and tube wall to realize reaching.

The wherein said method being reduced in the gliding speed of elephant trunk pipe bent position material arranges reduction of speed lobster back in elephant trunk pipe bent position, in this reduction of speed lobster back, the inclination angle of upper curved tube should be less than the inclination angle of lower curved tube, and described minimizing material is adopt to arrange buffering pipeline section in elephant trunk pipe bent position in the method for the contact of elephant trunk pipe bent position and tube wall.

The structure of buffering pipeline section comprises following two kinds:

1) when the supply pipe of elephant trunk is parallel with discharge nozzle; Boss is set at supply pipe and storage tank place and forms separator tube section;

2} is when the supply pipe of elephant trunk and discharge nozzle form the angle being less than 180 degree; Prolong the raw storing pipe that arranges at supply pipe pipe tail and form buffering pipeline section.

A kind of structure reducing the wearing and tearing of elephant trunk pipe bent position constructed by said method, as shown in drawings, comprise supply pipe 1 and the discharge nozzle 2 of elephant trunk, supply pipe 1 and discharge nozzle 2 shape have angle, it is characterized in that: the inclination angle a of supply pipe 1 is less than the inclination angle b of discharge nozzle 2, arrange storing pipe 3 in the life of prolonging of supply pipe 1 tail end, arrange at storing pipe 3 place and renovate 4, the length of this storing pipe 3 is 100-500mm.

During concrete use, stream material to be flowed directly in storing pipe by supply pipe and clashes into storing pipe, at the dirty material kinetic energy loss of effect of impact also oppositely, because inclination angle a is less than inclination angle b, make the not all right formation blocking phenomenon of supply pipe and discharge nozzle place, later stage flows material in a large number owing to storing in storing pipe, follow-up flow is only clashed into, and the flow be stored in storing clashes into, thus realize stream material and the contact of expecting pipe, reach purpose of design, and by renovating the stream material in periodic cleaning storing pipe, can ensure that cereal product quality is (if grain exists for a long time in storing pipe, can go bad).

Claims

1. one kind is reduced the structure of elephant trunk pipe bent position wearing and tearing, comprise supply pipe (1) and the discharge nozzle (2) of elephant trunk, supply pipe (1) and discharge nozzle (2) shape have angle, and it is characterized in that: the inclination angle (a) of supply pipe (1) is less than the inclination angle (b) of discharge nozzle (2).

2. a kind of structure reducing the wearing and tearing of elephant trunk pipe bent position according to claim 1, is characterized in that: arrange storing pipe (3) in the life of prolonging of supply pipe (1) tail end, arrange renovate (4) at storing pipe (3) place.
