Description
Technical Field
The invention relates to an air distribution plate, in particular to a simple small-sized air distribution plate.
Background
The existing air distribution plate is large and complex in structure, the industrial air distribution plate is mainly made of metal materials, and multiple structures are connected in a self-weight mode, so that the whole air distribution plate is complex in structure and large in weight, cannot be applied to a miniaturized experiment table, and is difficult to realize equal air distribution in an experiment, and undesirable results such as channeling, local dead zones and the like occur in a fluidized bed.
Disclosure of Invention
In order to solve the problems, the invention provides a simple small-sized air distribution plate.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a small-size grid plate of plain type includes hood, grid plate, air supply pipe joint, its characterized in that: the air inlet at the bottom of the air distribution plate is connected with an air supply pipe connector, and the top of the air distribution plate is in threaded connection with an air cap connector.
Furthermore, the inside of the air distribution plate is provided with a primary air distribution hole and a secondary air distribution hole, and the top air outlet, the air inlet and the air baffle fixing hole are internally provided with threads.
Furthermore, the bottom of the blast cap connector is provided with threads, the single blast cap is provided with a plurality of air exhaust holes, each hole is arranged in a downward inclined mode, and each air exhaust hole is arranged at an angle of 60 degrees.
The invention has the beneficial effects that:
through the symmetrical design of two-stage air distribution arranged in the air distribution plate, the air distribution plate can well ensure that each air outlet has the same flow resistance, thereby realizing equal air distribution; the upper part of the blast pipe joint at the bottom of the air distribution plate is in threaded connection with the air distribution plate, and the lower part of the blast pipe joint is connected with a blast pipe of a blower; the lower part of the blast cap at the top of the air distribution plate is fixedly connected with the air distribution plate through threads, and the opening of the blast cap is an inclined downward opening with a certain angle so as to prevent the particles in the fluidized bed from flowing back and generate certain rotating airflow to reduce dead zones in the bed; and a wind shield fixing hole is reserved on the side surface of the wind distribution plate and used for installing a connecting hole position reserved in the wind shield. This design is used as small-size test bench, and the material of selecting is light high temperature resistant material, can form through 3D printing as required, and low cost uses lightly, and has good air distribution ability for the data of experiment are more accurate.
