Abstract

The utility model relates to the field of large-diameter pipes for dust removal engineering and pneumatic transport engineering, in particular to a module combination type wear-resisting elbow comprising an elbow body. The elbow body is formed by sequential connection of a plurality of elbow sections along an axis. The module combination type wear-resisting elbow is characterized in that a combination module is arranged on an outer arc of each elbow section in a quick-wearing area, each combination module is connected with the corresponding elbow section through bolts and sealing elements, and the combination modules are interchangeable. Each combination module comprises a cover plate and a lining plate. The module combination type wear-resisting elbow has the advantages that the structure is novel, the elbow is divided into the elbow body and the interchangeable combination modules; the lining plates are partially thickened by common steel plates or made of wear-resisting materials, so that engineering cost is low; the combination modules are reusable, and production and running costs are saved; replacement is facilitated.

Description

A kind of module combined type abrasion-proof bent tube

Technical field

The utility model relates to the large-diameter pipeline field for the removing dust project of industrial and mineral, enterprise, strength conveying engineering, relates in particular to a kind of module combined type abrasion-proof bent tube.

Background technique

Bend pipe is the indispensable pipe element of cleaning shaft, Pneumatic conveying pipeline, accounts for about 10% of whole Piping component quality.In the actual moving process, bend pipe is worn through regular meeting, causes system's cisco unity malfunction.Through field observation and technical Analysis, the wearing and tearing of bend pipe always are present in the outer arc part area, rather than bend pipe integral body all is worn.Before this, people often adopt the wall thickness that increases bend pipe or adopt high-abrasive material to make bend pipe in order to prolong the working life of bend pipe.But in any case, wearing and tearing always exist, the bend pipe thing sooner or later that is worn through just.Also have the following disadvantages simultaneously, one, no matter be with the tube wall thickening of bend pipe or adopt high-abrasive material to make bend pipe, all can increase engineering cost, and give and make, install and cause difficulty; Even two, the some zones of bend pipe are worn through, whole bend pipe will be discarded, reinstall a new bend pipe, otherwise system causes the waste on the resource with regard to cisco unity malfunction.Three, in the actual production process, change tube bends and be a thing when taking a lot of work very much, can cause the influence of long period to system's operation.

Summary of the invention

The purpose of this utility model is the wear law at the major diameter bend pipe, and a kind of novel structure is provided, cheap, the module combined type abrasion-proof bent tube being convenient to safeguard.

In order to address the above problem, the utility model is realized by the following technical solutions:

A kind of module combined type abrasion-proof bent tube, comprise the bend pipe body, the bend pipe body is connected in sequence along axis by some pipeline sections, and the pipeline section outer arc in zone easy to wear is provided with composite module, be connected with Sealing by bolt between composite module and the pipeline section, it is interchangeable that each organizes composite module.

Described composite module comprises cover plate and liner plate.

Compared with prior art, the beneficial effects of the utility model are:

1) novel structure is divided into bend pipe body and replaceable composite module two-part with bend pipe, and manufacturing process is simple;

When 2) liner plate used common material to make, just liner plate was thickeied and bend pipe all need not be thickeied; When liner plate is high-abrasive material, is the part of module also, rather than all adopts high-abrasive material, thereby make engineering cost cheap;

3) composite module can be reused, and each is organized between the composite module and also can exchange, and has saved the production run cost;

4) composite module is changed and is made things convenient for the time spent short, influences explained hereafter hardly.

Description of drawings

Fig. 1 is the utility model example structure schematic representation.

Among the figure: 1-bend pipe body 2-composite module 3-Sealing 4-bolt 5-cover plate 6-liner plate

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

See Fig. 1, be a kind of module combined type abrasion-proof bent tube of the utility model example structure schematic representation, comprise bend pipe body 1, the bend pipe body is connected in sequence along axis by some pipeline sections, pipeline section outer arc in zone easy to wear is provided with composite module 2, be connected with Sealing 3 by bolt 4 between composite module 2 and the pipeline section, each organizes between the composite module 2 interchangeable.

Composite module 2 comprises cover plate 5 and liner plate 6, and liner plate can be changed.

Bend pipe heavy wear zone design is become several removable composite modules 2, and these composite modules 2 are installed on the bend pipe body 1; The material that liner plate 6 can use common (identical with bend pipe body material) is made; Also can use high-abrasive materials such as spheroidal graphite cast iron, cast stone and make, to obtain the longer replacement cycle.

In the actual using process, the wear condition of some composite modules on the visual bend pipe is in time changed, and guarantees the normal use of bend pipe; Can reuse after the module that changes is repaired, also can exchange between these composite modules.No matter liner plate is also to use high-abrasive material with common material, all be the whole of the part of module rather than module, more not the whole of bend pipe, both solve the pipe wear problem thereby reach, reduce the purpose of engineering cost, saving operating cost, minimizing resource consumption again.

The utility model bend pipe can require to carry out seriation, large-scale production according to caliber specification, the radius of curvature of cleaning shaft, Pneumatic conveying pipeline.
