Abstract
The utility model is a kind of bulb bend pipe for Geldart-D particle, comprises trap body, it is characterized in that: described trap body configuration design globulate.Described trap body structure is made up of a nestable interior bend pipe of outer bend pipe, and the space slush between two bend pipes is filled.Traditional semi major axis bend pipe or right angle type bend pipe are designed to spherical bend pipe by the utility model, increase the circulation section of bent tube section, pipe external lateral portion Flow of Goods and Materials is worsened, material is made to stagnate in pipe bent position wittingly, allow between material particles and mutually collide, the wearing and tearing to bend pipe wall can be prevented, thus effectively reduce corrosion and the degree of wear of bend pipe, the replacement frequency of bend pipe also reduces greatly, improves transfer efficiency.
Description
Technical field
The utility model relates to transporting system technical field, particularly relates to a kind of bulb bend pipe for Geldart-D particle.
Background technique
Geldart-D particle is a kind of mode of movement utilizing high velocity air to carry granular material in the duct.Be widely used in the industry of casting, chemical industry, medicine, grain.On conveying principle, the obvious difference of Pneumatic conveyer and other conveying equipments is: it is by transfer of air to the material be transported for the energy carried.For this reason, air need do the exchange of momentum while stirring material.Being detained bottom delivery pipe to not make to be transferred material, material will be made to maintain certain travelling speed.Like this, in air-transport system, bend pipe is as changing the assembly of throughput direction, and the particle in transfer and just create between tube wall and collide and clashes into, in Here it is the normal Pneumatic conveyer said, delivery pipe weares and teares cause.Wearing and tearing in pneumatic carrier in straight length are very light, and position easy to wear mainly occurs in pipeline turning place, particularly the outside of solid particle impact pipeline turning, Here it is bent wear.Wearing and tearing are inevitable, but, not only affected the normal work of device by the blowdown of abrading section, but also pollute the environment, destroy the tightness of whole system.Traditional bend pipe is generally designed to semi major axis bend pipe or right angle type, and in long-term Geldart-D particle, the corrosive wear of bend pipe is very serious, often need change bend pipe, have a strong impact on transfer efficiency.
Summary of the invention
The purpose of this utility model is intended to for solving the deficiencies in the prior art, and provides a kind of anticorrosive anti-wear bulb bend pipe for Geldart-D particle.
The utility model for achieving the above object, by the following technical solutions: a kind of bulb bend pipe for Geldart-D particle, comprises trap body, it is characterized in that: described trap body configuration design globulate.Described trap body structure is made up of a nestable interior bend pipe of outer bend pipe, and the space slush between two bend pipes is filled.
Described trap body is manufactured by ceramic-metal composite.
The beneficial effects of the utility model are: traditional semi major axis bend pipe or right angle type bend pipe are designed to spherical bend pipe by the utility model, increase the circulation section of bent tube section, pipe external lateral portion Flow of Goods and Materials is worsened, material is made to stagnate in pipe bent position wittingly, allow between material particles and mutually collide, the wearing and tearing to bend pipe wall can be prevented, thus effectively reduce corrosion and the degree of wear of bend pipe, the replacement frequency of bend pipe also reduces greatly, improves transfer efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bulb bend pipe for Geldart-D particle of the utility model;
Fig. 2 is the bend pipe structure schematic diagram for Geldart-D particle in prior art;
In figure: 1-conveyance conduit; 2-trap body; The outer bend pipe of 3-; Bend pipe in 4-.
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
Embodiment
Embodiment 1 one kinds is for the bulb bend pipe of Geldart-D particle
For a bulb bend pipe for Geldart-D particle, comprise trap body 2, it is characterized in that described trap body 2 profile is designed to spherical.When gas-solid mixture flows through the space of amplifying suddenly, first spread aftershrinkage, outside bulb trap body 2, respectively form a flow dead with inner side, the mixture flowed through directly is not contacted with wall, thus ensure not to be worn.
Described trap body structure is made up of a nestable interior bend pipe 4 of outer bend pipe 3, and the space slush between two bend pipes is filled.
Claims (2)
1. for a bulb bend pipe for Geldart-D particle, comprise trap body, it is characterized in that: described trap body configuration design globulate.Described trap body structure is made up of a nestable interior bend pipe of outer bend pipe, and the space slush between two bend pipes is filled.
2. the bulb bend pipe for Geldart-D particle according to claim 1, is characterized in that described trap body is manufactured by ceramic-metal composite.
