Description

Technical Field

[0001] This utility model relates to the field of sandblasting air compressor technology, specifically to an energy-saving sandblasting air compressor. Background Technology

[0002] In the field of sandblasting air compressor technology, traditional sandblasting equipment mostly adopts a single nozzle structure for sandblasting operations. However, single nozzles have obvious drawbacks in actual use:

[0003] Firstly, the continuous high-load operation of a single nozzle causes severe wear on the inner wall of the nozzle, especially the nozzle area, due to the high-speed scouring of sand particles. When the wear exceeds a certain level, the sandblasting efficiency drops significantly. Secondly, the single nozzle has a single sand supply channel. If the sand particles are wet or contain impurities, they are very likely to cause blockage at the feed inlet or throat, leading to interruption of spraying and affecting the uniformity of the workpiece surface treatment. Thirdly, to meet the sandblasting requirements of different workpieces, the single nozzle needs to frequently adjust the air pressure. This causes the air compressor to be frequently loaded / unloaded, resulting in a large amount of energy waste and unstable air pressure, which also affects the sandblasting quality. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving sandblasting air compressor, which has a single-nozzle mode and a multi-nozzle mode with main and auxiliary nozzles working in coordination. It has significant advantages. In the single-nozzle mode, when processing small-area workpieces or when high sandblasting accuracy is required, only the main nozzle or a set of auxiliary nozzles can be turned on. The motor drives the gears to mesh, causing the rotating disk to rotate and allowing the docking hole to connect with the branch pipe. This achieves precise control of the single nozzle and solves the problem that the high-speed erosion of sand particles causes severe wear on the inner wall of the nozzle, especially the nozzle part. When the wear exceeds a certain level, the sandblasting efficiency drops significantly.

[0005] To achieve the above objectives, an energy-saving sandblasting air compressor is provided, comprising a body, a high-pressure air pipe connected to the surface of the body, a connecting pipe connected to the end of the high-pressure air pipe, a control valve connected to the top of the connecting pipe, and the top of the control valve connected to the bottom of the body.

[0006] Also includes:

[0007] The system includes a main nozzle and auxiliary nozzles. The main nozzle is located at one end of the connecting pipe and is used for the main sandblasting work. Several sets of auxiliary nozzles are arranged in a circular array around the main nozzle and are used to assist the main nozzle in sandblasting.

[0008] As a further improvement to this technical solution, one end of the connecting pipe is connected to a main pipe, one end of the main pipe is connected to a connecting pipe, one end of the connecting pipe is connected to the main spray pipe, a turntable is rotatably connected to the surface of the connecting pipe, a connecting plate is fixedly connected to the surface of the turntable, a rotating disk is fixedly connected to the surface of the connecting plate, a connecting rod is fixedly connected to the bottom of the machine body, a locking plate is fixedly connected to the bottom of the connecting rod, and the locking plate is slidably connected to the rotating disk, the connecting pipe slider, and the sliding groove.

[0009] As a further improvement to this technical solution, a limiting ring is fixedly connected to one side of the rotating disk, a branch pipe is connected to the surface of the main pipe, the end of the branch pipe is located inside the limiting ring and contacts the side of the rotating disk, a docking hole adapted to the branch pipe is opened on the side of the rotating disk and inside the limiting ring, the auxiliary nozzle is fixedly connected to the other side of the rotating disk and communicates with the docking hole, a tooth is fixedly connected to the top of the rotating disk, a fixed frame is fixedly connected to the bottom of the machine body, a motor is fixedly connected to the top of the fixed frame, and a gear is fixedly connected to the output end of the motor through a coupling, the gear meshes with the tooth, and the path of the gear driving the tooth is just enough to make the docking hole dock with the branch pipe.

[0010] As a further improvement to this technical solution, the top of the machine body is connected to a sand filling port, the surface of the machine body is fixedly connected to an exhaust valve, and the surface of the machine body is fixedly connected to a filter.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this energy-saving sandblasting air compressor, the energy-saving sandblasting air compressor provided by this utility model has a single-spray pipe mode and a multi-spray pipe mode with main and auxiliary spray pipes working in coordination, which has significant advantages. In the single-spray pipe mode, when processing small-area workpieces or when the sandblasting accuracy requirement is high, only the main spray pipe or a certain set of auxiliary spray pipes can be turned on. The motor drives the gears to mesh with the teeth, causing the rotating disk to rotate and allowing the docking hole to connect with the branch pipe, thus achieving precise control of the single spray pipe. This mode can reduce unnecessary energy consumption, and the air compressor does not need to run at full load, reducing energy consumption. At the same time, it can also more accurately control the sandblasting pressure and flow rate, improving the accuracy of workpiece surface treatment.

[0013] 2. In this energy-saving sandblasting air compressor, in the multi-nozzle mode where the main nozzle and auxiliary nozzles are activated together, several sets of auxiliary nozzles are arranged in a circular array around the main nozzle. The rotation of the rotating disk connects the docking holes with the auxiliary nozzles, enabling multiple nozzles to work simultaneously. When processing large-area workpieces or in scenarios requiring high sandblasting efficiency, the multi-nozzle mode can significantly improve sandblasting efficiency. The main nozzle undertakes the main sandblasting work, while the auxiliary nozzles assist in the operation, forming a synergistic sandblasting effect. This allows the workpiece to be sandblasted in a shorter time. At the same time, through a reasonable air path design, the stability of the air pressure is ensured, making the sandblasting effect more uniform and improving the processing quality of the workpiece.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] This utility model provides an energy-saving sandblasting air compressor, which includes the following features:

[0024] For details, please refer to Figures 1-5 As shown, the device includes a body 1, which serves as the main body of the equipment. A sand inlet 2 is provided on the top to facilitate the addition of sandblasting material. An exhaust valve 3 is installed on the surface to release internal pressure when the equipment stops or the air pressure is abnormal, ensuring equipment safety. A filter 5 is also fixed on the surface to filter compressed air, remove impurities, improve air quality, and prevent impurities from entering the air circuit system and affecting the sandblasting effect and equipment operation.

[0025] The surface of the machine body 1 is connected to the high-pressure air pipe 4, and its end is connected to the connecting pipe 7, forming the main transmission channel of compressed air. The high-pressure air pipe 4 is responsible for transporting the high-pressure compressed air generated inside the machine body 1 to the connecting pipe 7. The connecting pipe 7 plays the role of collecting and distributing compressed air, providing a stable air source for subsequent sandblasting operations.

[0026] The top of the control valve 6 is connected to the connecting pipe 7. The top of the control valve 6 is connected to the bottom of the machine body 1. The control valve 6 can control the on / off state and flow rate of compressed air. When sandblasting is required, the control valve 6 is opened, and compressed air enters the connecting pipe 7 from the bottom of the machine body 1 through the control valve 6. By adjusting the opening of the control valve 6, the amount of compressed air entering the connecting pipe 7 can be precisely controlled, thereby achieving preliminary adjustment of the sandblasting pressure and flow rate.

[0027] The main nozzle 11, located at one end of the connecting pipe 7, is the primary sandblasting actuator, responsible for the main sandblasting work. One end of the connecting pipe 7 connects to the main pipe 8, and one end of the main pipe 8 connects to the connecting pipe 10. One end of the connecting pipe 10 connects to the main nozzle 11. Compressed air enters the main nozzle 11 through the connecting pipe 7, main pipe 8, and connecting pipe 10, mixes with the sandblasting material supplied from inside the machine body 1, and is then ejected from the main nozzle 11 to sandblast the workpiece. The diameter and structural design of the main nozzle 11 enable it to eject a sand stream with sufficient impact force under high sandblasting pressure, meeting the needs of large-area or high-intensity sandblasting operations. The auxiliary nozzle 22... Several sets of auxiliary nozzles 22 are arranged in a circular array around the main nozzle 11 to assist the main nozzle 11 in sandblasting. Each set of auxiliary nozzles 22 is fixedly connected to the other side of the rotating disk 14 and is connected to the branch pipe 9 through the docking hole 23. When the auxiliary nozzles 22 need to work, the rotating disk 14 rotates so that the docking hole 23 is connected to the branch pipe 9. Compressed air enters the auxiliary nozzles 22 through the branch pipe 9 and the docking hole 23, mixes with the sandblasting material, and is then sprayed out. The circular array distribution design of the auxiliary nozzles 22 can make the sandblasting coverage wider. When working together with the main nozzle 11, it can form a more uniform sandblasting effect and improve the efficiency and quality of workpiece surface treatment.

[0028] Turntable 12, connecting plate 13 and rotating plate 14 are connected. The surface of connecting pipe 10 is rotatably connected to turntable 12, the surface of turntable 12 is fixedly connected to connecting plate 13, and the surface of connecting plate 13 is fixedly connected to rotating plate 14. The bottom of machine body 1 is fixedly connected to connecting rod 15, and the bottom of connecting rod 15 is fixedly connected to locking plate 16. Locking plate 16 and rotating plate 14 are slidably connected through slider and groove. When turntable 12 rotates, it drives connecting plate 13 and rotating plate 14 to rotate together. Locking plate 16 is connected to slider and groove of rotating plate 14. On the one hand, it guides and limits the rotation of rotating plate 14, ensuring that rotating plate 14 can rotate stably around connecting pipe 10. On the other hand, the cooperation of slider and groove allows rotating plate 14 to rotate within a certain range, thereby realizing docking or disconnection of docking hole 23 and branch pipe 9.

[0029] A limiting ring 17 is fixedly connected to one side of the rotating disk 14. The surface of the main pipe 8 is connected to the branch pipe 9. The end of the branch pipe 9 is located inside the limiting ring 17 and in contact with the side of the rotating disk 14. The limiting ring 17 limits the branch pipe 9, ensuring that the branch pipe 9 is always located inside the limiting ring 17 and in contact with the side of the rotating disk 14. A docking hole 23 adapted to the branch pipe 9 is opened on the side of the rotating disk 14 and inside the limiting ring 17. When the rotating disk 14 rotates, the docking hole 23 rotates accordingly. When the docking hole 23 rotates to be aligned with the branch pipe 9, the branch pipe 9 is connected to the docking hole 23, and compressed air can enter the docking hole 23 through the branch pipe 9 and then enter the auxiliary nozzle 22. When the docking hole 23 rotates to be misaligned with the branch pipe 9, the branch pipe 9 is disconnected from the docking hole 23, and the auxiliary nozzle 22 stops working.

[0030] Motor 20, gear 21 and teeth 18: Teeth 18 are fixedly connected to the top of the rotating disk 14, and a fixed frame 19 is fixedly connected to the bottom of the machine body 1. Motor 20 is fixedly connected to the top of the fixed frame 19. The output end of motor 20 is fixedly connected to gear 21 through a coupling. Gear 21 meshes with teeth 18. When motor 20 is working, it drives gear 21 to rotate. Gear 21 meshes with teeth 18, thereby driving rotating disk 14 to rotate. By controlling the rotation direction and speed of motor 20, the rotation angle and speed of rotating disk 14 can be precisely controlled, so that docking hole 23 can accurately dock or disconnect with branch pipe 9, realizing the opening or closing control of auxiliary nozzle 22. The path of gear 21 driving teeth 18 is precisely designed so that docking hole 23 docks with branch pipe 9, ensuring that auxiliary nozzle 22 can accurately connect to compressed air and work normally when needed.

[0031] Working principle:

[0032] When processing small workpieces or requiring high sandblasting precision, a single-nozzle mode is used. In this mode, the motor 20 is started, driving the gear 21 to rotate. The gear 21 meshes with the teeth 18, driving the rotating disk 14 to rotate. By controlling the rotation of the motor 20, the mating hole 23 on the rotating disk 14 is aligned with the branch pipe 9 corresponding to a specific set of auxiliary nozzles 22. Alternatively, the main nozzle 11 can be used directly. Compressed air enters the main nozzle 11 through the high-pressure air pipe 4, connecting pipe 7, main pipe 8, and connecting pipe 10, or through the branch pipe 9 and mating hole 23. The corresponding auxiliary nozzle 22, since only the main nozzle 11 or a certain set of auxiliary nozzles 22 are opened, the air compressor does not need to operate at full load, reducing unnecessary energy consumption. At the same time, the pressure and flow of compressed air entering the single nozzle can be more precisely adjusted through the control valve 6, making the pressure and flow more stable during the sandblasting process, thereby improving the accuracy of the workpiece surface treatment. For example, when deburring small precision parts, only one set of auxiliary nozzles 22 is opened, and by precisely controlling the air pressure and flow, burrs can be accurately removed without damaging the surface of the parts.

[0033] When dealing with large-area workpieces or scenarios requiring high sandblasting efficiency, a multi-nozzle mode is adopted where the main nozzle 11 and the auxiliary nozzles 22 are opened together. The motor 20 is started to rotate the rotating disk 14, allowing multiple docking holes 23 to dock with the corresponding branch pipes 9. At the same time, the main nozzle 11 is also in working condition. Compressed air passes through the high-pressure air pipe 4 and the connecting pipe 7. Part of the compressed air enters the main nozzle 11 through the main pipe 8 and the connecting pipe 10, while the other part enters several sets of auxiliary nozzles 22 through the various branch pipes 9 and the docking holes 23.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
