Abstract
The utility model provides a whole spherical wear-resisting connector bend which belongs to the pipeline device and is characterized in that a feeding pipe and a discharging pipe which are intercommunicated are arranged on a sphere of a cavity, an included angle between the feeding pipe and the discharging pipe ranges from 90 DEG to 120 DEG, and the feeding pipe, the discharging pipe and the sphere are manufactured or welded into an integer, therefore, the whole spherical wear-resisting connector bend is installed in a pipeline used for pneumatic powder conveyance, a material deposit dead zone is formed in a sphere inner cavity corresponding to the included angle position of 90 DEG to 120 DEG between the feeding pipe and the discharging pipe, and powder is stacked in the dead zone, therefore, during the pneumatic powder conveyance process, and an air flow containing the powder only scours deposited materials without scouring the inner wall of the connector bend to cause the service life of the spherical connector bend to be greatly enhanced, thereby increasing the use rate of equipment, enhancing the production efficiency, lowering the cost, and reducing the pollution on environment.
Description
Technical field
The utility model metal conduit device especially relates to a kind of Pneumatic conveying pipeline elbow.
Background technique
On the bulk cement delivery line of metallurgy industry dry method powder delivery system and building material industry, elbow or bend pipe that the turning of its pipeline adopts wear resisting cast iron or cast steel to make usually, internal spray high-abrasive material at elbow, or employing hemisphere elbow, all work continuously but the gas of powder is defeated, elbow is contained washing away of powder air-flow and is suffered serious wearing and tearing, and all lack working life, must increase amount of maintenance, reduced manufacturing efficiency, increased cost, even can cause dust to leak and befouling environment, caused to produce and interrupt.
Summary of the invention
The purpose of this utility model is to propose a kind of global type wear-resistant bend, solves the elbow wear problems effectively, and not only long service life has reduced amount of maintenance, has reduced cost, and has protected environment, has improved the defeated working efficiency of powder gas.
The purpose of this utility model is achieved like this: a kind of global type wear-resistant bend, it is characterized in that on the spheroid of cavity, being provided with the supply pipe and the discharge nozzle of intercommunication, angle between supply pipe and the discharge nozzle is 90 °-120 °, supply pipe and discharge nozzle and spheroid are made one or integrally welded, in the pipeline of strength conveying powder, the global type wear-resistant bend is installed, powder when the high pressure draught band and enter sphere cavity from supply pipe, discharge from discharge nozzle then, corresponding to 90 °-120 ° angle position between supply pipe and the discharge nozzle, in sphere cavity, just form the buildup dead band, powder is piled up in this dead band, like this, carry in the process of powder in strength, the air-flow that contains powder only washes away the buildup in the dead band, and can not wash away the inwall of elbow, is greatly improved the working life of spherical elbow, increased the utilization rate of equipment, improved manufacturing efficiency, reduced cost, reduced pollution environment.
The global type wear-resistant bend that the utility model proposes, rational in infrastructure, safe and reliable, long service life has improved manufacturing efficiency, has reduced cost, has reduced the pollution to environment.
Now the global type wear-resistant bend of in conjunction with the accompanying drawings and embodiments the utility model being carried is described further.
Description of drawings
Fig. 1 is the main cross-sectional schematic of the global type wear-resistant bend that proposes of the utility model.
Among Fig. 1: 1, supply pipe 2, spheroid 3, discharge nozzle
Embodiment
As can be seen from Figure 1: a kind of global type wear-resistant bend, it is characterized in that on the spheroid 2 of cavity, being provided with the supply pipe 1 and the discharge nozzle 3 of intercommunication, angle between supply pipe 1 and the discharge nozzle 3 is 90 °-120 °, supply pipe 1 and discharge nozzle 3 are made one or integrally welded with spheroid 2, like this, in the pipeline of strength conveying powder, the global type wear-resistant bend is installed, powder when the high pressure draught band and enter spheroid 2 inner chambers from supply pipe 1, discharge from discharge nozzle 3 then, angle position corresponding to 90 ° between supply pipe 1 and the discharge nozzle 3-120 °, just form the buildup dead band in spheroid 2 inner chambers, powder is piled up in this dead band, like this, carry in the process of powder in strength, the air-flow that contains powder only washes away the buildup in the dead band, and can not wash away the inwall of elbow, and is greatly improved the working life of spherical elbow, increased the utilization rate of equipment, improved manufacturing efficiency, reduced cost, reduced pollution environment.
