Abstract
The utility model discloses a fan air intake gas barrier bars for robot. Include the grid tray and fix the drum on the grid tray circumference, the grid tray is the circular slab, and the equipartition has a plurality of angles type grid side by side on the surface, go up to the side of drum week and open threaded hole. The utility model discloses an on a metal plectane, through the mode of mould punching press, rush out a plurality of angle type grids, the grid of angular form structure makes when the air inlet, and the air current is in the angular form grid gets into the fan, for the following current, when reverse -flow, the velocity of flow of wind slowly flows under the hindrance of the open end of angle type grid, has controlled the process of fan state change, through the fixed drum of week side at the grid tray for install on the air intake of fan portion dress, the air intake gas barrier bars of this fan portion dress have processing simple manufacture, and process flow is short, preparation low cost, characteristics such as excellent in use effect.
Description
Technical field
This utility model belongs to industrial machine technical field, particularly relates to a kind of for industrial machine cooling fan air inlet trapping grid.
Background technology
Blower fan is a vitals of forced-ventilated radiator, for supply and the discharge of flue gas of air；Operation principle is that motor rotarily drives wind wheel rotation, and wind wheel and Fan casing jointly act on air intake vent and form negative pressure suction air.
The air inlet of the blower fan portion dress of prior art uses bivalve folded plate type barrier, and this bivalve folded plate type barrier is by when air intake vent forms negative pressure suction air, opening the bivalve folded plate type barrier closing air inlet under negative pressure, enter air；This structure is a kind of passive type air inlet barrier, and under the effect of external force, bivalve folded plate type barrier easily collides with air port, produces bigger noise, and, can only air inlet, it is impossible to giving vent to anger, when breaking down, easy accumulated heat burns out motor.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, a kind of air inlet trapping grid for robot are provided, by on a circular metal plate, by the way of mould punching, if going out arterial highway angle-style grizzly bar, the grizzly bar of angular structure makes when air intake, and air-flow enters in blower fan along dihedral grizzly bar, for following current；When reverse-flow, the flow velocity of wind, under the obstruction of the opening of angle-style grizzly bar, slowly flows out, and controls the process of fan condition change, and the grille structure of the air inlet solving existing fan of gas water heater portion dress is complicated, the problem that cost of manufacture is high.
For solving above-mentioned technical problem, this utility model is achieved through the following technical solutions:
This utility model provides a kind of air inlet trapping grid for robot, including screen and the cylinder being fixed on screen circumference；Described screen is circular slab, and surface is evenly equipped with some angle-style grizzly bars side by side；Screwed hole is had on described cylinder week side.
Further, described cylinder is fixed on screen circumference by the way of welding, and the air inlet that described cylinder fills with blower fan portion is slidably matched, and is fixed by screws in inside the air inlet of blower fan portion dress.
Further, the angle-style grizzly bar on described screen is formed by mould punching；Outside the port of the air inlet that the tip of described angle-style grizzly bar fills towards blower fan portion, inside the port of the air inlet that opening fills towards blower fan portion.
This utility model has the advantages that
This utility model is a kind of air inlet trapping grid for robot, by a circular metal plate, by the way of mould punching, if going out arterial highway angle-style grizzly bar, the grizzly bar of angular structure makes when air intake, and air-flow enters in blower fan along dihedral grizzly bar, for following current；When reverse-flow, the flow velocity of wind, under the obstruction of the opening of angle-style grizzly bar, slowly flows out, and controls the process of fan condition change；
A cylinder is fixed, for being arranged on the air inlet of blower fan portion dress by all sides at screen；It is simple that the air inlet trapping grid of this blower fan portion dress have processing and fabricating, the features such as technological process is short, and cost of manufacture is cheap, and using effect is good.
Certainly, implement arbitrary product of the present utility model to it is not absolutely required to reach all the above advantage simultaneously.
