Abstract
A zero-pressure sand blasting device is used to solve the problem that the conventional sand blasting device requires pressure to work. The zero-pressure sand blasting device comprises a sand blasting tank and an air delivery pipe, an air compressor is connected with one end of the air delivery pipe, a spray gun is connected with the other end of the air delivery pipe through a rubber pipe; and the improvement is that the air delivery pipe passed through the lower part of the sand blasting tank, a sand inlet pipe is arranged at a part in the sand blasting tank, the air delivery pipe is further provided with a sand blowing branch pipe, and the outlet end of the sand blowing branch pipe is positioned inside the sand blasting tank and is corresponding to an inlet of the sand inlet pipe. The zero-pressure sand blasting device provided by the utility model has the characteristics that the sand blasting tank can work without pressure, so that the sand blasting tank can be manufactured according to the standard of ordinary containers, which can greatly reduce the equipment cost, simplify the operation maintenance procedure, and eliminate the potential safety hazard; the sand outlet amount of the sand blasting tank is realized by the adjustment of air of an adjusting valve, so that the valve cannot be blocked by sands, which can greatly prolong the service life of the adjusting valve; and the zero-pressure sand blasting device can ensure the continuity of operation, so as to solve the problem that the operation in assembly lines is interrupted by adding sands.
Description
Technical field
The utility model relates to a kind of no pressure sand blasting unit, belongs to the abrasive blast equipment technical field.
Background technology
Sand blasting unit is a kind of workpiece to be carried out surface-treated equipment, and it sprays to the workpiece to be machined surface after utilizing compressed air that sand is quickened, and makes workpiece obtain certain cleannes and different roughness, can also increase the adhesive force of workpiece corrosion-inhibiting coating.During constituting, existing sand blasting unit comprises a sand-spraying pot, the sand-spraying pot top is provided with the charge door that can seal, the bottom of sand-spraying pot is the taper shape that helps the smooth and easy discharge of sand, sand-spraying pot is communicated with air compressor machine through appendix, a branch road of appendix enters in sand-spraying pot feeds compressed air jar, is provided with spray gun at the port of export of appendix.The sand blasting unit of this ordinary construction need seal sand-spraying pot by compressed air pressure charging in use, and the sand in the sand-spraying pot is by falling certainly and compressed air release with joint efforts.The problem that exists is: be to carry out having under the pressure condition during sand-spraying pot operation, the pressing force container is treated, and exists certain danger in operating process; The pressure vessel manufacturing all has strict requirement, cost of manufacture height to quality, thickness, the welding of steel; Pressure vessel in use also needs to carry out periodic inspection, maintenance.
The utility model content
The utility model is used to overcome the defective of prior art and a kind of no pressure sand blasting unit that reduces equipment cost, use safety is provided.
The alleged problem of the utility model is that following technical scheme solves:
A kind of no pressure sand blasting unit, comprise sand-spraying pot and appendix in the formation, appendix one end connects air compressor machine, the other end connects spray gun through sebific duct, its special feature is: described appendix is passed by the bottom of sand-spraying pot, its position that is positioned at sand-spraying pot is provided with sand-feeding tube, and described appendix also is provided with the blast arm, and the port of export of blast arm is positioned at sand-spraying pot and corresponding with the sand-feeding tube inlet.
A kind of no pressure sand blasting unit, constitute and comprise sand-spraying pot and appendix, appendix one end connects air compressor machine, the other end connects spray gun through sebific duct, special feature is: the bottom of described sand-spraying pot is provided with out sandpipe, go out the sandpipe outlet and incorporate appendix into, described appendix also is provided with the blast arm, and the port of export of blast arm is positioned at the bottom of sandpipe.
Above-mentioned no pressure sand blasting unit, described blast arm is provided with control valve.
The utility model need improve with the problem of pressure operation at traditional sand blasting unit, it picks out the blast arm at the appendix place, the blast effect of the compound blast arm of siphonage that produces when utilizing air to flow through sprays sand, and reaches the control sand production rate by the control valve control tolerance that is provided with on the blast arm.Compare with common sand blasting unit, characteristics of the present utility model are as follows: 1. sand-spraying pot need not to work under pressure state, so sand-spraying pot gets final product according to the standard manufacture of common vessel, greatly reduces equipment cost, simplify the operation maintenance link, and eliminated the potential safety hazard of pressure vessel; 2. the sand-spraying pot sand production rate is to rely on control valve to reconcile tolerance to realize, because the obstructed valve that overregulates of sand so this valve the sand clogging can not occur, has obviously prolonged the service life of control valve; 3. the continuity that can keep operation, the utility model sand-spraying pot charge door opens wide, and can add sand in sandblast operation limit, limit in jar, has solved the problem of being interrupted work because of additional sand in the sand jar on the streamline.
Description of drawings
Fig. 1 is the utility model first scheme structural representation;
