| 4. Structure | |
| Structural layout | The equipment adopts the method of on-site assembly of walk-in storage plate, and the structure layout is roughly divided into: chamber structure, dust collection system, dust blowing system, control system, etc |
| Laboratory body | Warehouse material: environmental friendly and flame-retardant rigid polyurethane foam with thickness of 100mm, assembled on site; Outer wall material: milky white steel plate Inner wall material: SUS304 stainless steel plate Sealing: the joint is sealed with imported glass silica gel, which is resistant to silicon oil corrosion; Thermal insulation material: environmental friendly flame-retardant rigid polyurethane foam with a thickness of about 100mm, strong thermal insulation performance |
| Chamber bottom | At the bottom is the unit room, including the bottom plate grid of the room body, guide rail for loading, dust collection funnel, vibrator, fan, channel steel underframe, etc Bearing capacity: total bearing capacity at the bottom ＞ 3T |
| Gate | Gate: manual double hinged door, the size of the door opening is 1800 × 2800 mm; the door sealing strip has strong aging resistance and dust tightness resistance. Observation window: each gate is equipped with a glass observation window, the size is about 500mm wide × 650mm high. A manual dust scraper is installed to observe the test situation of the sample in the box. |
| Lighting installation | Two sets of damp proof and explosion-proof lamps are installed on the top of the room, and the switch is controlled on the control panel. |
| Pressure relief balance | One pressure balance port to prevent the pressure of the upper air box from being too high and dust from leaking out |
| 5. Dust collection and blowing system | |
| Dust collecting funnel | Equipped with six cone-shaped dust collection funnels made of stainless steel, which gather near the blow hole of the inner box when the dust falls, and equipped with periodic vibrator and dust discharge port, the dust can be taken out when the machine is stopped. |
| Vibrator | Strong vibrator, adjustable vibration time and period, make the dust attached to the inner wall fall to the bottom of cone funnel, make the dust concentration uniform |
| Dust blowing method | The sand dust in the dust collection funnel is blown into the test room through the dust blower at the upper air outlet of the side of the test room for sand dust test |
| Dust filtration | Precision dust filter, filter bag, balance the pressure inside and outside the box |
| Dust blower | In order to meet the dust blowing requirements of the whole space, 6 sets of high-power medium pressure fans are equipped. The fans drive the dust of a certain concentration to the test object, and the air flow direction is from up to down. |
| Dust drying | Install heating ring in front of dust outlet pipe to dry and recycle dust Heater control mode: contactless equal period pulse width adjustment, SSR (solid state relay) |
| Schematic diagram of dust blowing |  |
| Heating dehumidification | Adopt 304 stainless steel heating device, heat and dehumidify to keep the dust dry |
| 6. Control system | |
| Controller | Controller: 7-inch LCD, touch screen programmable controller Display: TFT true color display resolution 800 × 600; display temperature, pressure, test time, etc Operation mode: program mode and fixed mode; Program capacity: 999 programs, each program has a maximum of 999 steps, 999 cycles can be set, and programs can be linked; Time setting: set arbitrarily within 999h69m59s, and control the floating dust time, vibration time and vacuum time separately; Auxiliary functions: it has man-machine dialogue function, which can be expanded through standard RS232 communication interface to realize remote monitoring of equipment, optional network interface (LAN), fault alarm and cause, processing prompt function; power-off protection function, timing function (automatic start and stop), fault display and self diagnosis function: emergency troubleshooting manual, maintenance manual; Recording function: memory accumulation test time; |
