As shown in Figure 1 to Figure 3, a kind of sand dust test chamber, including airtight test casing 1, the pipeline 3 testing casing 1 and blower fan 2 for the blower fan 2 and connection controlling circulation of air flow in test casing 1. Described test casing 1 be provided with for supply flow into test box house air inlet 11, for flowing out the return air inlet 12 of test casing for air-flow and for observing the observation window 13 of the test environment of test box house. Wherein, bottom and the top of described test casing 1 are V-shaped structure. The bottom of test casing 1 is V-shaped structure, and air inlet is arranged on its lowest position of the bottom of test casing 1; The top of test casing 1 is inverted v-shaped structure, and return air inlet arranges the highest position at the top of test casing 1, and air-flow enters in test box body from the bottom of test casing, flows out from the top of test casing. So that the air-flow of test box house can circulate, improve the utilization rate of dust, being provided with blower fan 2 on pipeline 3 between air inlet and the air outlet of test casing, blower fan 2 is arranged on the lower section of test casing 1, and outside the pipeline 3 between air inlet and return air inlet.Wherein, described blower fan 2 is turbofan, and the return air inlet of test casing is connected with the air inlet of turbofan by pipeline, and the air outlet of turbofan is connected by the air inlet of pipeline with test casing. It is additionally provided with in described test box body for guiding the deflector 4 of air flow direction in test box body, for placing the mounting table 5 of product to be measured, for providing the illuminating lamp 14 of light source, the air velocity transducer 15 for monitor in real time test box house wind speed, the Temperature Humidity Sensor 16 for monitor in real time test box house temperature and humidity for test box house and surveying the sensor of dust concentration 17 of dust concentration for monitor in real time. Described sensor of dust concentration 17 is photo-electric dust concentration meter, air velocity transducer 15 and Temperature Humidity Sensor 16 is the air velocity transducer sold on existing, market and Temperature Humidity Sensor all can realize, and the manufacturing enterprise of air velocity transducer and Temperature Humidity Sensor and concrete model is not enumerated and is elaborated at this. Described deflector 4 is arranged on bottom the V-shaped of test casing 1. Described deflector 4 includes left side deflector 41, middle part deflector 42 and right side deflector 43, middle part deflector 42 is vertically arranged in the centre position bottom the V-shaped of test casing 1, left side deflector 41 and right side deflector 43 distribution and is arranged on the left and right sides of middle part deflector 42 and tilts to the both sides of test casing 1. Described left side deflector 41 and right side deflector 43 are symmetrical with middle part deflector 42 for axis of symmetry. Being arranged over mounting table 5 at deflector, mounting table 5 is positioned at the middle position of test casing 1, during test, is placed on by test product and tests on mounting table. Wherein said mounting table 5 can adopt mounting table conventional in existing test casing. Pipeline between return air inlet and the air inlet of turbofan of described test casing is sequentially provided with vacuum cleaner 8 and storage vat 7. Described vacuum cleaner is for controlling the dust concentration of test box house, and wherein vacuum cleaner can adopt the vacuum cleaner sold on existing, market. After being completed, draw the dust in test box body by vacuum cleaner, it is achieved the automatic recovery of dust, save manpower, improve dust organic efficiency, and dust can be recycled. Described storage vat is dust storage device conventional in existing test device, the known general knowledge being well known to those skilled in the art. Described sand and dust test box also includes a PLC control system, it is shown that PLC control system be existing control system. Described PLC control system is connected with illuminating lamp 14, air velocity transducer 15, Temperature Humidity Sensor 16, sensor of dust concentration 17, blower fan 2, vacuum cleaner 8 and storage vat 7, and the wind speed in test box body, humiture and dust concentration information are transmitted to PLC control system in real time by air velocity transducer 15, Temperature Humidity Sensor 16 and sensor of dust concentration 17, PLC control system controls blower fan 3, vacuum cleaner 8 and storage vat 7 and works. Described PLC control system is operated realization according to the dust concentration control storage vat that sensor of dust concentration 17 is monitored in real time and the dust concentration in test box body is adjusted. During work, setting the concentration value of dust in PLC control system, when setting concentration in the dust concentration in the test box body monitored in real time is lower than PLC control system, PLC control system controls storage vat 7 and adds dust in test box body by pipeline; Dust concentration in the test box body of monitoring in real time is higher than when setting concentration in PLC control system, and PLC control system controls vacuum cleaner 8 by pipeline sucking-off test box internal body portion dust.
In order to increase the wind speed in test box body, reduce the power of blower fan, reduce the energy consumption of the requirement to blower fan and blower fan, between air inlet and the pipeline being connected with air inlet of test casing, be provided with an airflow accelerator 6. Housing 61 that this accelerator includes column and the acceleration block 61 being arranged in housing multiple strips, it is internal that this acceleration block 61 fixes housing 61 vertically, increase the empty air motion in housing by accelerating block, produce bigger air-flow so that enter the air-flow in test box body bigger. The described block 62 that accelerates is the cylinder 621 that cross section is triangle, and the front end accelerating block 62 is triangular pyramidal 622. The front end of acceleration block is provided with triangular pyramidal can reduce the resistance of air-flow, improves wind speed. Described cylinder 621 is parallel with the sidewall of described housing 61. Entering when air-flow exports from fan outlet in accelerator, owing to the stream pressure in pipeline is constant, but the space in accelerator is reduced so that the speed of air-flow is accelerated, it is achieved the acceleration of air-flow.
Accelerate block except the acceleration block described in the present embodiment described in above example, it is also possible to for the acceleration block accelerating block or other structures that cylindrical structure and front end are cone, itemize elaboration at this.
Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims. It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these apparent alternative forms belong to protection domain of the present utility model.
