Description

Technical Field

[0001] This utility model belongs to the field of refrigerator drain pipe sandblasting technology, specifically a sandblasting treatment device for refrigerator drain pipe production. Background Technology

[0002] Sandblasting the refrigerator drain pipe increases its surface roughness. The impact and cutting action of the abrasive on the pipe surface creates a uniform and rough surface structure. This rough surface helps improve the adhesion between the coating and the inner wall of the pipe, allowing the coating to adhere more firmly and thus enhancing the pipe's wear and corrosion resistance.

[0003] Utility model patent CN219131970U discloses a high-efficiency sandblasting device, comprising a main body, an internal rotary sandblasting device, and an electric telescopic rod. One end of the electric telescopic rod is fixedly connected to the inner wall of the main body, and the other end is fixedly connected to a lifting plate. One side of the lifting plate is fixedly connected to a sliding plate, and the sliding plate is slidably connected to a sliding groove plate. Both ends of the sliding groove plate are fixedly connected to the inner wall of the main body. A first sliding groove is machined on the surface of the sliding plate, and the sliding plate is slidably connected to a translation plate through the first sliding groove. The lower end of the translation plate is slidably connected to a second groove machined on a horizontal plate. In the above patent document, when sandblasting a workpiece, the workpiece is placed on a rotating wheel, and then sandblasted using a sandblasting head. However, the sandblasting head is fixedly connected to the bottom of the sand storage tank, and the nozzle faces directly downwards, so sandblasting can only be performed in a fixed direction, resulting in poor flexibility during sandblasting. In view of this, it is necessary to propose a sandblasting device for the production of refrigerator drain pipes. Utility Model Content

[0004] The purpose of this invention is to provide a sandblasting device for the production of refrigerator drain pipes, which can improve the flexibility of sandblasting refrigerator drain pipes.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A sandblasting treatment device for refrigerator drain pipe production includes a sandblasting cabinet, a rotating mechanism, a sandblasting mechanism, a purification mechanism, and a sandblasting adjustment mechanism. The sandblasting mechanism is installed on the left side of the sandblasting cabinet, the purification mechanism is installed on the right side of the sandblasting cabinet, the rotating mechanism is installed at the top of the sandblasting cabinet, and the sandblasting adjustment mechanism is installed on the inner wall of the upper left side of the sandblasting cabinet.

[0008] Furthermore, the sandblasting adjustment mechanism includes a U-shaped groove, which is fixedly connected to the upper inner wall of the sandblasting cabinet. A second motor is fixedly connected to one inner wall of the U-shaped groove, and a second rotating rod is fixedly connected to the output end of the second motor. The end of the second rotating rod away from the second motor is rotatably connected to the other inner wall of the U-shaped groove through a bearing. Several sandblasting guns are fixedly connected to the outer surface of the second rotating rod. The internal cavity of the sandblasting gun is connected to a flexible hose, and the end of the connecting pipe away from the diverter pipe passes through the side wall of the sandblasting cabinet and is connected to the flexible hose.

[0009] Furthermore, the purification mechanism includes a purification box, which is fixedly connected to the outer right side of the sandblasting cabinet.

[0016] In this invention, during sandblasting, several refrigerator drain pipes are fitted onto several positioning posts. The sandblasting machine is then started, and compressed air and abrasive are delivered from the conveying pipe to the distribution pipe for distribution. This allows the compressed air and abrasive to enter the sandblasting gun through the connecting pipe and hose and be ejected to sandblast the refrigerator drain pipes. Starting the motor causes the rotating rod to rotate the turntable, which in turn rotates the refrigerator drain pipes, facilitating sandblasting. As the turntable rotates, the sandblasting gun can also pass through the gaps between the refrigerator drain pipes to sandblast the previously un-sandblasted surfaces. The rotating rod also slightly rotates the sandblasting gun, allowing adjustment of the nozzle direction and the sandblasting angle on the refrigerator drain pipes. This combination of structures improves the flexibility of sandblasting the refrigerator drain pipes. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1-3A sandblasting treatment device for refrigerator drain pipe production includes a sandblasting cabinet 1, a rotating mechanism 2, a sandblasting mechanism 3, a purification mechanism 4, and a sandblasting adjustment mechanism 5. The sandblasting mechanism 3 is installed on the left side of the sandblasting cabinet 1, the purification mechanism 4 is installed on the right side of the sandblasting cabinet 1, and the rotating mechanism 2 is installed at the top of the sandblasting cabinet 1. The sandblasting adjustment mechanism 5 is installed on the inner wall of the upper left side of the sandblasting cabinet 1, and a filter screen 11 is fixedly connected to the inner wall of the middle part of the sandblasting cabinet 1.

[0023] The rotating mechanism 2 includes a motor 21, which is fixedly connected to the upper surface of the sandblasting chamber 1. A rotating rod 22 is fixedly connected to the output end of the motor 21. The end of the rotating rod 22 away from the motor 21 extends movably into the interior of the sandblasting chamber 1 and is fixedly connected to a turntable 23. Several positioning posts 24 are fixedly connected to the upper surface of the turntable 23. A sealing door 15 is hinged to the front side of the sandblasting chamber 1, and a handle 16 is fixedly connected to the outer surface of the sealing door 15. Specifically, the sealing door 15 is opened using the handle 16, and several refrigerator drain pipes are then fitted onto the positioning posts 24. Starting the motor 21 causes the rotating rod 22 to rotate the turntable 23, which in turn rotates the refrigerator drain pipes, facilitating sandblasting by the sandblasting mechanism 3 and the sandblasting adjustment mechanism 5.

[0024] Reference Figures 1-3 The sandblasting mechanism 3 includes a sandblasting machine 31, which is fixedly connected to the left outer wall of the sandblasting cabinet 1. The output end of the sandblasting machine 31 is connected to a conveying pipe 32, and the end of the conveying pipe 32 away from the sandblasting machine 31 is connected to a diversion pipe 33. The diversion pipe 33 is fixedly connected to the upper left outer wall of the sandblasting cabinet 1, and the internal cavity of the diversion pipe 33 is connected to several connecting pipes 34. The sandblasting adjustment mechanism 5 includes a U-shaped groove 51, which is fixedly connected to the upper inner wall of the sandblasting cabinet 1. A motor 52 is fixedly connected to one inner wall of the U-shaped trough 51. A rotating rod 53 is fixedly connected to the output end of the motor 52. The end of the rotating rod 53 away from the motor 52 is rotatably connected to the other inner wall of the U-shaped trough 51 through a bearing. Several sandblasting guns 54 are fixedly connected to the outer surface of the rotating rod 53. A flexible hose 55 is connected to the internal cavity of the sandblasting gun 54. The end of the connecting pipe 34 away from the diverter pipe 33 passes through the side wall of the sandblasting cabinet 1 and is connected to the flexible hose 55.

[0025] Specifically, starting the sandblasting machine 31 delivers compressed air and abrasive from the conveying pipe 32 to the diversion pipe 33 for diversion. This allows the compressed air and abrasive to enter the sandblasting gun 54 through the connecting pipe 34 and the hose 55 and be ejected to sandblast the refrigerator drain pipe. Simultaneously, starting the motor 21 causes the rotating rod 22 to rotate the turntable 23, which in turn rotates the refrigerator drain pipe, facilitating sandblasting by the sandblasting gun 54. When the turntable 23 rotates, the sandblasting gun 54 can also pass through the gaps between several refrigerator drain pipes to sandblast the previously un-sandblasted surfaces. Simultaneously, starting the motor 52 causes the rotating rod 53 to rotate, which in turn slightly rotates the sandblasting gun 54, allowing adjustment of the nozzle direction and sandblasting angle of the refrigerator drain pipe. This combination of structures improves the flexibility of sandblasting the refrigerator drain pipe.

[0026] The purification mechanism 4 includes a purification chamber 41, which is fixedly connected to the right outer wall of the sandblasting cabinet 1. A second filter plate 45 and an activated carbon filter layer 46 are installed sequentially from left to right on the inner wall of the purification chamber 41. An air guide pipe 44 is connected to the upper internal cavity of the sandblasting cabinet 1, with the end of the air guide pipe 44 away from the sandblasting cabinet 1 connected to the left internal cavity of the purification chamber 41. An exhaust pipe 47 is installed on the right side of the purification chamber 41, and the internal cavity of the exhaust pipe 47 is connected to the right internal cavity of the purification chamber 41. A valve 48 is installed on the outer surface of the exhaust pipe 47. Specifically, the airflow generated during sandblasting can enter the purification chamber 41 through the air guide pipe 44, and the second filter plate 45 and the activated carbon filter layer 46 can purify the air entering the purification chamber 41. Opening the valve 48 allows the purified air to be ejected from the exhaust pipe 47, reducing pollution to the surrounding environment.

[0027] A sealing door 2 42 is hinged to the front side of the purification chamber 41, and a handle 2 43 is fixedly connected to the outer surface of the sealing door 2 42. Specifically, when it is necessary to clean the filter plate 2 45 and the activated carbon filter layer 46, the handle 2 43 can be grasped to open the sealing door 2 42 for cleaning. The bottom internal cavity of the sandblasting cabinet 1 is connected to the discharge pipe 13, and a valve 14 is installed on the lower outer surface of the discharge pipe 13. Support plates 12 are fixedly connected to both ends of the lower surface of the sandblasting cabinet 1. The inner bottom surface of the sandblasting cabinet 1 slopes from all sides towards the upper opening of the discharge pipe 13. Opening the valve 14 allows some abrasive material that has fallen into the inner bottom surface of the sandblasting cabinet 1 to be discharged from the discharge pipe 13 for cleaning by the staff.

[0028] To better illustrate this utility model, its working principle is described in detail below:

[0029] When using this device, first connect an external power source. Use handle 16 to open the sealing door 15. Then, attach several refrigerator drain pipes to several positioning posts 24. Next, start the sandblasting machine 31 to deliver compressed air and abrasive from the conveying pipe 32 to the diversion pipe 33 for diversion. This allows the compressed air and abrasive to enter the sandblasting gun 54 through the connecting pipe 34 and the hose 55 and be sprayed out to sandblast the refrigerator drain pipes. At the same time, start the motor 21 to make the rotating rod 22 drive the turntable 23 to rotate, thereby driving the refrigerator drain pipes. The rotating mechanism facilitates sandblasting of the refrigerator drain pipe by the sandblasting gun 54. When the turntable 23 rotates, the sandblasting gun 54 can also pass through the gaps between several refrigerator drain pipes to perform sandblasting on the surfaces of the refrigerator drain pipes that were not previously sandblasted. At the same time, the motor 22 can be started to rotate the rotating rod 23. The rotating rod 23 will drive the sandblasting gun 54 to rotate slightly, thereby adjusting the nozzle direction of the sandblasting gun 54 to adjust the sandblasting angle on the refrigerator drain pipe. The combination of the above structures can improve the flexibility of sandblasting the refrigerator drain pipe.

[0030] On the other hand, the airflow generated during sandblasting can enter the purification chamber 41 through the air guide pipe 44, and the filter plate 45 and activated carbon filter layer 46 can purify the air entering the purification chamber 41. Opening valve 48 can allow the purified air to be sprayed out from the exhaust pipe 47, reducing pollution to the surrounding environment. When it is necessary to clean the filter plate 45 and activated carbon filter layer 46, the handle 43 can be held to open the sealing door 42 to clean the filter plate 45 and activated carbon filter layer 46.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
