Abstract
The invention discloses a dedicated non-abrasion sand suction elbow for pneumatic conveying material device and manufacturing method thereof. The dedicated non-abrasion sand suction elbow for pneumatic conveying material device comprises an elbow body. The elbow body comprises a vertical section, a slopping section, and a horizontal section. The inner surface of the slopping section is provided with an impact-resistant plate. The impact-resistant plate comprises a plurality of impact-resistant plate unit cells. Compared with the prior art, the dedicated non-abrasion sand suction elbow for pneumatic conveying material device and manufacturing method thereof have the advantages that the dedicated non-abrasion sand suction elbow for pneumatic conveying material device which is protected has no abrasion after being used, and the manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of pneumatic convey material device-specific and inhale sand elbow and manufacture method thereof without wearing and tearing.
Background technology
The conveying adopting pneumatic convey (or claim wind model) mode to carry out material or abrasive material is more and more widely used in all trades and professions, the application particularly in the industry such as machinery, grain, application, chemical industry, environmental protection, building.What pneumatic convey adopted is closed conduct conveying, in usual pipe, wind speed is comparatively large (depending on a few grain size of material material, 10-40 meter per second can be reached), the wearing and tearing of impact to pipeline of material are relatively large, and especially the elbow of pipeline is the most easy to wear causes damaged gas leakage have impact on carrying operation normally.Current popular technical measures channel bend place are increased thickness of pipe or adopt high abrasion resisting material to increase the elbow life-span, reduces and safeguard and change number of times.But these 2 kinds of methods all cannot change channel bend to be continued to be worn until the result of leakage, elbow can only be extended and be about 1-3 doubly (thickness increased depending on material and material status) service life, when carrying out the conveying of sharp-pointed or the larger material of hardness, the often elbow life-span shorter (1 month less than), cause maintenance of equipment frequent, not only increase use cost, also can cause production loss because of stopping production maintenance.A kind of up-to-date technology is badly in need of to change current this situation in pneumatic convey field.
Summary of the invention
An object of the present invention is just to provide a kind of pneumatic convey material device-specific to inhale sand elbow without wearing and tearing, without wearing and tearing after this pneumatic convey material device-specific uses without wearing and tearing suction sand elbow, and low cost of manufacture.
Technical scheme is: a kind of pneumatic convey material device-specific inhales sand elbow without wearing and tearing, comprise elbow body, this elbow body is made up of vertical section, tilting section and horizontal segment, and described tilting section inside face is provided with resistance to punching, and this resistance to punching is made up of the some unit of resistance to punching sub-boxes.
As preferably, the described unit of resistance to punching sub-box is of a size of 15mmx15mmx20mm.
As preferably, the described unit of resistance to punching sub-box adopts 2mm plate iron.
As preferably, the described unit of resistance to punching sub-box is welded on described tilting section inside face.
Two of object of the present invention is to provide a kind of pneumatic convey material device-specific to inhale the preparation method of sand elbow without wearing and tearing.
Prepare above-mentioned pneumatic convey material device-specific inhales a sand elbow method without wearing and tearing, comprise the following steps:
1. the enchashment elbow body that has method to produce;
2. get 2mm plate iron, make the unit of resistance to punching sub-box in elbow body tilting section inside face surrounding, grid wall thickness is 2mm, and make rear each grid and be of a size of 15mmx15mm, the degree of depth is 20mm, the bottom of each grid and tilting section inside face weld together.
Compared with prior art, inventive principle of the present invention and beneficial effect are:
In common pipe wear, material is directly to impact at a high speed the bending part of elbow, and rear by the follow-up pipe motion that renews in bounce-back change direction, because long-time continuous is impacted, elbow bending part very easily weares and teares.The present invention is not the pattern adopting material washing pipe, but adopts the pattern of material punching material.Namely at elbow bending part, the object of material impact is not elbow material itself, but the material be deposited in.Equipment initial operating stage; material automatically can fill up these frame slots and form delay material; subsequent material impacts comes only to impact the change realizing direction after these are detained material; Elbow material itself is owing to being separated with delay material with impact material; directly can not be impacted, thus be achieved the protection to elbow.
Elbow baseboard material of the present invention, without wearing and tearing, eliminates maintenance herein and replacing, can be user and saves a large amount of use cost.
The present invention has stopped equipment and has keeped in repair because changing elbow stopping production the production loss brought.
