Abstract
The invention discloses an outer axial strip screen cylinder. The outer axial strip-shaped screen cylinder includes a single-block outer net layered up and down, and each single-block outer net in each layer of single-block outer net is arranged around the axis of the outer axial strip-shaped screen cylinder. The single piece of outer net includes screen bars, and the length direction of the screen bars is parallel to the axial direction of the outer axis of the bar screen cylinder. A top connecting plate and a bottom connecting plate are respectively arranged on the top and bottom of the outside of the sieve bars in the single external net, and connecting rod holes are arranged on the top connecting plate and the bottom connecting plate. A support plate is provided between the outer side of the screen bar and between the top connecting plate and the bottom connecting plate. The outer axial strip screen cylinder is provided with a connecting rod, and the connecting rod passes through the upper and lower coaxial connecting rod holes from the top to the bottom of the outer axial strip screen cylinder. The invention can be used in various process equipments such as reactors, regenerators and filters in industries such as petrochemical industry and metallurgy.
Description
technical field [0001] The invention relates to an outer axial strip screen cylinder used in process equipment in petrochemical industry and other industries. Background technique [0002] Bar screen (also known as Johnson net) is a general industrial product, which is widely used in metallurgy, oil refining, chemical industry, medicine, etc. Filtration, gas-solid or gas-liquid distribution, gas-solid or gas-liquid separation and other process equipment in , food, water treatment and other industries. The axial bar screen cylinder is a kind of bar screen, which is composed of a circular support ring and a screen bar. The cross-sectional shape of the screen bar is an isosceles triangle, and the length direction is parallel to the axial direction of the axial bar screen cylinder. The axial strip screen cylinder includes an inner axial strip screen cylinder (abbreviated as inner net) and an outer axial strip screen cylinder (abbreviated as outer net). The annular support rin...
