A KF40 interface formed in the upper end of a conveying straight pipe is connected with vacuum collection machinery, guide plates are arranged in a collecting opening formed in the lower end of the conveying straight pipe, adjusting screw nuts are installed at two ends of fixing shafts which are used for fixing the guide plates, and the collecting opening is driven to carry out vertical movements through the stepping-motor-screw mode. When the materials with particle diameters which are smaller than 20mm are collected on flat ground, air volume of the vacuum collection machinery is adjusted to 3200-3400m3/h, collecting depth of the vacuum collection machinery is 28-32mm, inclined angles, relative to the ground, of the guide plates is adjusted to 40-50 degrees through the fixing shafts and the adjusting screw nuts, and equal thickness collection is achieved. When particle collection is carried out on rolling ground, the height, relative to the ground, of collecting opening is adjusted to 4-6mm through the stepping-motor-screw mode, and copying thickness collection is achieved.
Description
Technical field
The present invention relates to engineering machinery field, carry out improvement and bring new ideas to apparatus structure and collection mode, the equal thickness for ground loose solid particles is collected, thus realizes engineering machinery collects degree of depth controllability to solid granule.
Background technology
Be subject in chemistry or earth's surface, radioactive pollution region pollutant control engineering, the principle that vacuum collecting machinery is collected due to its negative pressure, the spatter property that can realize pollutant is collected, and without reentrainment of dust and cross pollution.In order to realize the controllability of collecting the degree of depth in vacuum collecting machinery operation process, devise the collection mouth and corresponding collection method that are applicable to the actinal surface even flow field that solid pollution composition granule equal thickness is collected.Utilize fluid calculation software, numerical simulation has been carried out to this inside and outside flow field of collection mouth, has proposed the thinking installing deflector in inside additional, change the distribution of suction inlet External airflow field.
The innovation of this collection method is divided into two parts: collect the structure optimization of mouth and the innovation of collection method.First hydrodynamics technology is utilized to be optimized collection opening structure, deflector changes the thinking of collecting mouth interior flow field and to still belong to the first time at home proposition, according to the collection mode of this collection mouth, propose and utilize vertical adjustment mechanism and stepper motor-screw rod two kinds of modes under laboratory and field condition, regulate collection mouth relative to the distance on ground respectively, thus achieve and under smooth ground and rolling ground, the equal thickness of solid particle is collected, and by regulating the air quantity of vacuum collecting machinery and collecting the distance of mouth relative to ground, can control to collect the degree of depth.
Summary of the invention
The object of the invention is to: for realizing the controllability of contaminant collecting, the suction inlet being applicable to the actinal surface even flow field that loose contamination solid particle equal thickness is collected of design, has important practical value.
The object of the present invention is achieved like this: a kind of method utilizing adjusting device collection material, and device is made up of KF40 interface 1, conveying straight tube 2, collection mouth 3, deflector 4, fixed axis 5, adjusting nut 6; The KF40 interface 1 being arranged on conveying straight tube 2 upper end is connected with vacuum collecting machinery, be arranged on the interior laying deflector 4 of collection mouth 3 of conveying straight tube 2 lower end, fixed axis 5 two ends of fixing deflector 4 are installed with adjusting nut 6, drive collection mouth 3 to move up and down relative to ground by the mode of stepper motor-screw rod; When collecting granules footpath, level land grain is less than 20mm, the air quantity regulating vacuum collecting machinery is 3200-3400m
3/ h, the collection degree of depth is 28-32mm, and regulates deflector 4 to be 40-50 ° relative to the Inclination maneuver on ground by fixed axis 5 and adjusting nut 6, realizes equal thickness and collects; When rolling ground carries out powder collection, collecting mouth 3 relative to the height on ground by the type of drive adjustment of stepper motor-screw rod is 4-6mm, and the thickness realizing profiling is collected.
Apparatus of the present invention mainly comprise KF40 interface, conveying straight tube, collect mouth, fixed axis and deflector, by regulating deflector installation dimension and mounted angle, make velocity variations near deflector little, without eddy current, same level line overdraught speed average is high, amplitude of variation is little, thus obtains the optimum size of structure suction inlet, simultaneously, according to material size, the size of collecting the degree of depth and hypsography in collection process, this kind of collection method also can realize equal thickness, shows technological progress.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, invention is described further.
Accompanying drawing 1 is suction port assembly structural representation;
As shown in the figure: 1-KF40 interface, 2-carry straight tube, 3-collects mouth, 4-deflector; Utilize KF40 interface and vacuum collecting machinery to be connected, namely by the mode of stepper motor-screw drive, regulate the distance of collection mouth and hopper, realize effective collection of the pollutant to fine sand and glass marble.
Accompanying drawing 2 is deflector structure schematic diagram;
As shown in the figure: 5-fixed axis, 6-adjusting nut; Utilize the adjusting nut collecting mouth deflector fixed axis both sides, realize the adjustment to deflector inclination angle.
Detailed description of the invention
Below in conjunction with embodiment, invention is described further.
Embodiment
Device is made up of KF40 interface, conveying straight tube, collection mouth, deflector, fixed axis, adjusting nut; When collecting granules footpath, level land grain is less than 20mm, the air quantity regulating vacuum collecting machinery is 3300m
3/ h, the collection degree of depth is 30mm, and regulates deflector by fixed axis and adjusting nut, is 45 ° relative to the Inclination maneuver on ground, realizes equal thickness and collects; When rolling ground carries out powder collection, collecting mouth relative to the height on ground by the type of drive adjustment of stepper motor-screw rod is 5mm, and the thickness realizing profiling is collected.
Checking suction inlet collecting effect, collects the structural design of mouth, and installs and flow field analysis deflector;
1) deflector installation dimension L1, L2 and D and the ratio of collection width L and the setting angle of deflector are optimized, result shows, when D is 5mm, and L1/L and L2/L is when being 0.5,0.25, deflector optimum embedding angle degree is 45 °, collection mouth both sides air velocity is now the highest, and on the outside same level line of collection mouth, average speed is the highest, velocity variations amplitude is minimum.
