Description

Technical Field

[0001] This utility model relates to the field of sandblasting equipment technology, and in particular to an energy-saving and environmentally friendly sandblasting equipment. Background Technology

[0002] The principle of sandblasting equipment is mainly to use compressed air or other power to propel abrasive materials at high speed onto the surface of an object. Through the impact and friction of the abrasive materials, the surface quality of the object is improved. Metal workpieces are usually polished by sandblasting equipment during processing or cleaning, so that dirt, rust, old coatings and other impurities on the surface are removed due to the impact, thereby achieving the purpose of cleaning the surface.

[0003] Compressed air blasting equipment is a type of blasting equipment that uses compressed air as power to propel abrasive particles onto the surface of a workpiece. Small compressed air blasting equipment typically requires operators to wear gloves, holding the workpiece in one hand and the blast gun in the other. Abrasive particles from the blast gun can easily spray onto the operator's arms or outside the equipment without their knowledge, causing skin or clothing damage, abrasive loss, and dust inhalation, impacting the operator's health. To address these issues, we have developed this energy-saving and environmentally friendly blasting equipment. Utility Model Content

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, an energy-saving and environmentally friendly sandblasting equipment includes a first housing 1, a material guide shell 5, and a second housing 14. The top of the first housing 1 is equipped with a lighting lamp (not shown in the figure). The material guide shell 5 is a shell that slopes from both sides towards the middle, and the ground in the middle has a slope that slopes towards the discharge pipe 6. A placement rod 4 is fixedly connected to the inner wall of the middle material guide shell 5. Two mounting plates 12 are fixedly connected to the side wall of the first housing 1. The two mounting plates 12 are equipped with a protective door 2 through a rotating shaft. The side wall of the protective door 2 is equipped with an observation window.

[0023] The protective door 2 has a protective mechanism on its side wall to prevent abrasive impact. The protective mechanism includes two protective gloves 3 set on the side wall of the protective door 2. The bottom of the second box 14 is fixedly connected to the abrasive tank 9 and the compressor 10. The side wall of the abrasive tank 9 is connected to the spray gun 15 through the spray pipe 8. The compressor 10 is connected to the spray gun 15 through the air outlet pipe. The air outlet pipe is equipped with an air filter and a pressure regulating valve. The spray pipe 8 is equipped with a sand valve. The lower end of the guide shell 5 is connected to the recovery tank 7 through the discharge pipe 6. The lower end of the recovery tank 7 is equipped with a discharge pipe 11. The right side of the recovery tank 7 is equipped with a discharge pipe. Both the discharge pipe and the discharge pipe 11 are equipped with valves. The discharge pipe is not shown in the figure. The discharge pipe is used to discharge dust particles.

[0024] The recycling tank 7 is equipped with a filtration mechanism for filtering abrasives. The filtration mechanism includes a filter screen cylinder 13 fixedly connected to the top of the recycling tank 7. The lower end of the filter screen cylinder 13 is connected to the upper end of the feed pipe 11, and the lower end is connected to a connecting housing.

[0025] In this utility model, a screw conveyor 20 is installed at the bottom of the second housing 14. The end of the connecting shell away from the discharge pipe 11 is connected to the screw conveyor 20. The screw conveyor 20 is connected to the abrasive tank 9 through a connecting pipe, which sends the recovered abrasive back into the abrasive tank 9, realizing the reuse of abrasive and saving energy.

[0026] In this utility model, the upper ends of multiple placement rods 4 are fixedly connected to a placement frame 16, and a stop bar 17 is provided through the side wall of the placement frame 16.

[0027] In this utility model, a motor 19 is fixedly connected to the upper end of the upper mounting plate 12.

[0028] In this invention, the inner wall of the filter cylinder 13 is provided with an inclined surface, and the observation window is made of tempered glass to improve the explosion-proof effect of the observation window.

[0029] It should be noted that this utility model is an energy-saving and environmentally friendly sandblasting equipment. The user places the workpiece on the placement rod 4 by rotating the protective door 2. After closing the protective door 2, the user puts both hands into two protective gloves 3, picks up or holds the workpiece with one hand, and picks up the spray gun 15 with the other hand. Pressing the spray gun 15, the compressor 10 compresses air into the spray gun 15 as power. The airflow creates a negative pressure in the spray gun 15, which draws the abrasive into the spray gun 15 and ejects it through the nozzle onto the surface to be processed. The user can sandblast and polish the workpiece surface by adjusting the angle of the workpiece or the angle of the spray gun 15. The abrasive enters the recovery tank 7 along the inclined surface of the guide shell 5. During the process, the protective door 2 can prevent the abrasive from being sprayed directly onto the operator's skin and causing skin damage, and can also prevent the operator from inhaling dust and affecting their health.
