The specific embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of locomotive with removing sand device, is installed on sandbox A bottom.Described sandbox A can be various sandbox of the prior art.As shown in Figure 1:
The structure of described sander B as Figure 1-5, comprise and be provided with the stucco body of chamber 9 and the high pressure air channel being communicated with chamber 9, upright dividing plate 16 is divided into entering sand chamber 15 and shaking out chamber 17 of top connection from described chamber 9 bottoms, describedly enter sand chamber 15 and from top, be divided into by the chamber wall 22 that suspends of chamber 9 bottom is communicated with enter sand chamber 20 and raise sand chamber 21, describedly enter sand chamber 20 and be communicated with sandbox A outlet, described raise 21 tops, sand chamber be provided be communicated with high pressure air channel raise sand tuyere 7, to flow into into sand chamber 20 from sandbox A, through entering 20 bottoms, sand chamber, enter the sand of raising sand chamber 21 and dig to blow and boil to the chamber 17 that shakes out again, described chamber 17 tops that shake out are provided with and are communicated with high pressure air channel, the tuyere 5 that shakes out that the sand that boils is blown out from the sand export 18 that is arranged at chamber 17 bottoms that shake out.
Particularly, described stucco body B comprises assembling all-in-one-piece stucco body top 11 and stucco body bottom 19, described stucco body bottom 19 base seals by stucco body top 11 form the chamber 9 of stucco body, the sand export 18 of chamber 17 of shaking out is oppositely arranged up and down with described blast tuyere 5, to be conducive to blowing out of sand.Described dividing plate 16 is uprightly fixed on the upper surface of stucco body bottom 19, as further optimization, the distance L of described dividing plate 16 tops and described chamber 9 wall end faces is 15-19mm, excessive, the sand grains that can cause crossing dividing plate is too many, even may make sand grains cross dividing plate because of the operation vibrations of locomotive, flow out voluntarily, otherwise, the too small sand grains that can cause crossing dividing plate very little, the described distance L 1 of entering chamber wall 22 bottoms to the described dividing plate top that suspends of sand chamber 15 is 8-12mm, define and raise sand height, described chamber wall 22 bottoms that suspend of entering sand chamber 15 are 16-20mm to entering sand chamber 15 distance from bottom L2.Excessive, can cause sand grains to be piled up too high, from tuyere excessively close to, easily stop up tuyere, it is poor that the sand grains that guarantees tuyere and accumulation has certain altitude, actv. has been avoided sand grains obstruction tuyere possibility.Otherwise the too small sand grains piling height that can cause is too low, raises sand diff-H excessive.Above-mentioned preferable range defines sand grains piling height, raises sand height, by the restriction of above-mentioned preferable range, raises sand flow smooth, can blow out uniformly and stably sand grains.
Further preferably, due to inevitable bulky grain foreign material in actual production medium sand, described stucco body bottom 19 is also provided with and is positioned at into sand removing holes 12 sand chamber 15 bottoms, openable.Preferably, in working order under, sand removing hole 12 is sealed by sand plug 13, by further sealing of sand plug lid 14, dismantles if desired sand plug 13, can open sand removing hole 12, to entering in sand chamber 15, clears up, and regularly removes foreign material.
Described high pressure air channel is arranged in the chamber wall on stucco body top 11 and is connected high-pressure blast is provided with outside high-pressure air source by through hole thru-bolt joint 1, and the air pressure of high-pressure blast is 200 ~ 600kPa.In the present embodiment, described high pressure air channel is the segmentation beeline channel that processing obtains in the chamber wall on described stucco body top 11, particularly, stucco body top 11 is processed with air channel I 3, vertical air channel II 4, the air channel III 6 of level, wherein air channel I 3 communicates with air channel II 4, air channel II 4 communicates with air channel III 6, II 4 ends in air channel are sealed air channel II 4 by thread connection by holding screw 8 with extraneous, the end of air channel III 6 is sealed air channel III 6 by thread connection by holding screw 8 with extraneous, form cecum.
Because its inner air channel adopts integral body, process, avoided adopting the loaded down with trivial details technique of parts weldering splicing, simple in structure, good seal performance, dependable performance, technical parameter can be set by relevant criterion requirement, is easy to dismounting and exchange.
Preferably, described in, enter sand chamber 15 and be also provided with the normal tuyere 10 of dry sand.The normal tuyere 10 of the described dry sand normal pressure source of the gas outside with another is connected, and the wind blowing out is in atmospheric pressure state, and blast is very little, is not enough to blow sand grains, but can be blown in sand heap and infiltrate between sand grains, prevents that sand grains from hardening.
Further, sander B is provided with heating plate 2, it is comprised of PTC heating plate and hot conductive can, it is arranged at sander B top, and arranges around sandbox A bottom, is adjacent to sandbox A bottom during installation, for dry sandbox A and the sand grains that enters sander B cavity, and keep sand grains dry, and coordinate the normal tuyere 10 of dry sand to use together, make sand grains drying effect better.
Because heating plate 2 is the electric boiling plate of PTC material, it has excellent temp auto-controlled characteristic, and its resistance value can change with temperature, compares traditional resistor silk and heats more energy-conserving and environment-protective.As shown in Figure 3, pressurized air is led to the normal tuyere 10 of dry sand; By locomotive blast, provide atmospheric air, the air of normal tuyere 10 ejections of dry sand has formed the wind circulation of sandbox inside, the heat transmission that heating plate 2 is produced, and having realized sander B has inner heated-air drying sand grains, prevent in cavity 9, especially enter the object that the interior sand grains of sand chamber 15 hardens.Heating plate 2 is U-shaped structure, can wrap up sander B cavity (enter sand chamber 15, chamber 17 shakes out), makes, in its heated perimeter in heating plate 2, to make it higher to the heated perimeter of sand grains and efficiency.
Described stucco body top 11 surface working have 4 uniform mounting holes that connect with sandbox A, and described mounting hole is 64.5-65.5 mm at the pitch-row H of length direction, at the pitch-row B of Width, is 89.5-90.5 mm.This installation dimension designs for being applicable to syntonic type electric locomotive sandbox.
Working process of the present utility model is: the rear continuation stacked stream in sand chamber 20 that enters that sand grains enters sander enters to raising in sand chamber 21, when locomotive needs stucco, open the valve in high pressure air channel, making air pressure is that the pressurized air of 200 ~ 500kPa enters through hole thru-bolt joint 1 through locomotive blast, by high pressure air channel, in the present embodiment, high-pressure blast is through air channel I 3, air channel II 4, after air channel III 6, send into blast tuyere 5, raise sand tuyere 7, the pressurized air of raising sand tuyere 7 ejection will be entered sand grains in sand chamber 20 and boil, the pressure gas that the sand grains having boiled is blown out by blast tuyere 5 after dividing plate 16 is discharged through sand export 18 by the chamber 17 that shakes out.
The utility model sander model is TQS1-Z, can be used as the sander of the harmonious locomotives such as HXD1, HXD1B, HXD1C.Dependable performance, trial effect is good, and indices all meets the requirement of iron mark, is a kind of wide accommodation and the reliable special-purpose sander of harmonious locomotive.
