Embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
To shown in Figure 5, a kind of rotary dust and sand effect device comprises head 1, switch board (not drawing among the figure), head movable stand 2, circular orbit 3 and rotation sprayer 4 like Fig. 1; Said head 1 is a casing, offers air inlet and air outlet on the casing, and frequency conversion fan 11, electric heater 12 and air-flow honeycomb screen lattice 13 are installed in the casing successively; Head 1 is fixed on the head movable stand 2, and head movable stand 2 is installed on the circular orbit 3, and is provided with motor driver it can be moved on circular orbit 3; Also be provided with truss 6 on the said head movable stand 2; Truss 6 comprises vertical rack 62 and level frame 61; Level frame 61 can move up and down along vertical rack 62 under the driving of motor, also is provided with guide rail on the level frame 61, and rotation sprayer 4 is installed on this guide rail; Rotation sprayer 4 is connected with the air outlet of head 1 through bellows 5, and bellows 5 is provided with sand dust cast feeder 7, measuring wind speed appearance (not drawing among the figure), sand-dust concentration measuring instrument 8 with the junction of shower nozzle 4.Said rotation sprayer 4 can be done 180 ° swing in level and vertical direction.Also be provided with the sense of rotation of manual adjustments rotation sprayer 4 and the regulating device of angle (not drawing among the figure) on the said truss 6.
Said switch board is installed in the outside, laboratory, prevents the pollution of sand dust.Be provided with test routine control circuit, humidity control circuit, temperature-control circuit, wind speed control circuit, sand-dust concentration control circuit, head motion control circuit, illumination control circuit in the switch board.Said switch board is in order to the rotation of control rotation sprayer 4 and move, and head movable stand 2 move the temperature of sand dust air-flow, wind speed, sand dust content, the humidity of test space, temperature, illumination.
When making an experiment, build an airtight laboratory, breadboard size, size design according to test products, can be convenient to the turnover and the arrangement of test products, and enough this test units of space mounting are arranged.At first lab space is done to reduce the control of humidity, this test unit is installed on therebetween.The temperature of sand dust air-flow, wind speed, sand dust content by the control of this test unit, are applied directly on the test products, and this test unit moves along circular orbit 3, hit thereby each face of 4 pairs of test products of realization rotation sprayer carries out blowing of different angles.
For small sized product, when the area of test face is less than or equal to the sand dust air-flow spout of rotation sprayer 4, then can rotation sprayer 4 is fixing, regulate the ejection angle, manual or automatic transfer test product can be accomplished the test to each test face; Also can small sized product be placed on the platform that can do 270 ° of rotations, the head 1 of dust and sand effect device is fixed, and only rotation sprayer 4 is done to move and rotate, and its each facade and end face are made an experiment.
For large product, the principle according to effect equates is divided into many little test sections with big test face, moves rotation sprayer 4 and makes an experiment successively, adopts the method for plodding away at a big job bit by bit, and accomplishes the bulk testing of large product.
