Abstract

The utility model discloses a sanding device. The sanding device comprises a sanding body with a cavity, wherein a sand outlet pipeline penetrating through the sanding body is arranged on the sanding body, an exhaust pipeline communicated with the sand outlet pipeline is further arranged on the sanding body, a heating body is arranged in a cavity of the sanding body, a compressed air channel communicated with the cavity is formed on the sanding body, a box body is arranged outside the sand outlet pipeline, a gap is formed on the box body, a gas nozzle is arranged on one side of the sand outlet pipeline, the gas nozzle is communicated with the compressed air channel, and the gas nozzle is positioned in the box body. According to the sanding device disclosed by the utility model, centralized air blowing is realized through the gas nozzle arranged on one side of the sand outlet pipeline, so that the problem that the sand outlet pipeline is blocked by sand particles is prevented.

Description

Sander

Technical field

The utility model relates to a kind of locomotive sand sprayer.

Background technology

Locomotive is when rail running, in order to prevent tyre skidding, sander is all set conventionally on locomotive, when locomotive driving, sand grains is scattered in orbit, avoid tyre skidding to cause danger, but sand grains is at humidity easy caking afterwards, and the sand grains after caking cannot spread out smoothly from sander, easily causes the locomotive wheeslip in travelling and causes danger.

Based on above-mentioned defect, the applicant is designing a kind of sander, and applied for patent, application number is " 201120238699.7 ", its structure is as Fig. 1, mainly comprise sandbox 1, sandbox 1 bottom connects stucco unit 3, in 3 upper ends, stucco unit, be provided with sintered plate 5, sintered plate 5 has small pore, in sintered plate 5 upper ends, stucco pipeline 4 is set, stucco pipeline 4 upper ends arrange door 40, during use sintered plate 5 lower end chambers pass into after pressurized air is kicked up sand grains on sintered plate 5 to strike baffle plate 40, enter sand pipe road 4 in after fall on motorcycle track, but in use procedure, find that sand easily stops up at baffle plate 40 and stucco pipeline 4 cooperation places, cause normally stucco, therefore be necessary above-mentioned defect to improve.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of sander.

The utility model is achieved by the following technical solution: sander, comprise the stucco body with chamber, on described stucco body, be provided with the sand pipeline that goes out that connects described stucco body, on described stucco body, be also provided with the gas exhaust duct with the described pipeline communication that shakes out, in the chamber of stucco body, calandria is set, on described stucco body, offer the compressed air channel being communicated with described chamber, described go out sand pipeline be outside equipped with box body, on described box body, breach is set, described go out sand pipeline one side valve is set, described valve is communicated with described compressed air channel, described valve is positioned at described box body.

In technique scheme, described in go out sand pipeline upper end flaring opening be set, flaring hatch frame is used for increasing knockout area, ensures enough sands and can fall in opening.

In technique scheme, described opening is near a side direction sunken inside of described valve, the sand of kicking up by valve is more prone to enter out in the opening of sand pipeline under the guiding at the depression position of opening, and the structure of depression has increased the gap that sand pipeline and box side wall, prevented the problem that sand stops up at this place.

In technique scheme, in the upper end of described sander, be provided with dust-filtering plate.

The utlity model has following beneficial effect: by concentrating blowing at the valve that goes out sand pipeline one side setting, prevented that sand grains from stopping up out the problem of sand pipeline.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, referring to Fig. 1 to Fig. 6, sander, be arranged at sandbox below, comprise the stucco body 1 with chamber, on described stucco body 1, be provided with connect described stucco body 1 go out sand pipeline 2, described go out sand pipeline 2 be outside equipped with box body 6, on described box body 6, breach 60 is set, described go out sand pipeline 2 one sides valve 7(valve 7 is set near a tool side jaggy), described valve 7 is communicated with described compressed air channel.Described go out sand pipeline 2 upper ends flaring opening 20 is set, described opening 20 is near a side direction sunken inside of described valve 7.During use, pass into pressurized air in compressed air channel, compression is given vent to anger sand grains is kicked up by valve 7, drops in flaring opening 20 after striking box body 6 inwalls, then from going out sand pipeline, drops into motorcycle track.By concentrating blowing at the valve that goes out sand pipeline one side setting, prevented that sand grains from stopping up out the problem of sand pipeline.

On described stucco body 1, be also provided with described go out the gas exhaust duct 3 that is communicated with of sand pipeline 2, calandria 4 is set in the chamber of stucco body 1, on described stucco body 1, offer the compressed air channel 5 being communicated with described chamber.In the upper end of described sander 1, be provided with dust-filtering plate 8, by in the interior ventilation of compressed air piping 5, wind sees through dust-filtering plate 8 and blows the sand in sandbox after 4 heating of calandria in chamber, reach the function of drying sand, hot blast and the steam of drying in sand grains process are finally discharged by gas exhaust duct 3.Further preferred, in described gas exhaust duct 3 bottoms, be provided with the control apparatus that regulates gas exhaust duct 3 exhaust diameters, this control apparatus comprises a setting nut 13, described setting nut 13 has the end face of truncated cone-shaped, in described gas exhaust duct 3 bottoms, be provided with the through hole 17 coordinating with described setting nut 13, the degree of depth that enters through hole 17 by setting nut 13 regulates the air output of gas exhaust duct 3, thereby controls the bake out temperature in sandbox.

The first baffle plate 61 of outside turnover is set in breach 60 lower ends of described box body, the second baffle 62 of inside turnover is set in breach 60 upper ends.Being convenient to sand grains can enter in box body along breach.
