Technical Field
[0001] The utility model relates to the technical field of purification equipment, in particular to sandblasting dust protection and purification equipment. Background Art
[0002] Sandblasting is a process for surface treatment of workpieces. It uses compressed air as a power source to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating.

However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0014] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate directions or positional relationships based on the attached Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.
[0015] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0016] In order to solve the above technical problems, Figure 1-2As shown, the utility model relates to a sandblasting dust protection and purification device, including a protection box 1, wherein support columns are arranged at the four corners of the bottom of the protection box 1, and the inner side of the protection box 1 is used to place a sandblasting device (as shown in the figure), and the sandblasting device can be a conventional handheld spray gun type sandblasting machine. The protection box 1 is equipped with a purification treatment mechanism, and a baffle 2 is arranged on the front side of the protection box 1, and the baffle 2 is fixedly connected to the protection box 1 by bolt connection. The installation connection is stable and the disassembly and assembly are also convenient. The baffle 2 is provided with a visual window 3, an operation port 4, and a discharge port 5 from top to bottom, and the visual window 3 is provided with glass, and the worker can clearly observe the inside of the protection box 1 through the glass. In order to prevent the workpiece from being damaged, the operating port 4 is provided with gloves, which are preferably made of rubber material with high strength and flexible use. The worker can put his hands into the two gloves and then operate the spray gun of the sandblasting device inside the protective box 1 to sandblast the workpiece. In addition, the discharge port 5 is provided with a rotatable cover door, and the inner side of the protective box 1 is also provided with a support plate 6 for placing the workpiece. The worker can place the workpiece on the support plate 6 through the cover door, and the cover door is only opened during the material replacement operation and is in a closed state during sandblasting, so as to avoid large-scale leakage of dust-containing airflow. The setting of the protective box 1 allows workers to operate the sandblasting process normally while avoiding damage from dust-contaminated airflow.
[0017] It is further preferred in this embodiment that the purification treatment mechanism includes a dust suction pipe 7, a fan 8, an exhaust pipe 9, and a filter cartridge 10. The dust suction pipe 7 is located on the inner side of the protective box 1 and its air intake port faces downward. A dust suction hopper 11 is preferably provided at the bottom of the dust suction pipe 7. The dust suction hopper 11 has a conical structure that is small at the top and large at the bottom, which can increase the area of the suction port. The fan 8 is used to suck the airflow from the dust suction pipe 7 and lead it out from the exhaust pipe 9. The exhaust pipe 9 can also be connected to other pipeline systems to directly discharge the treated airflow outward. A filter cartridge 10 is installed in the dust suction pipe 7. Preferably, there are several filter cartridges 10, and several filter cartridges 10 are installed in the dust suction pipe 7 in a rectangular distribution. The setting of the filter cartridge 10 can adsorb and filter particulate pollutants such as dust in the airflow, thereby completing the purification of the dust-containing airflow, so that the discharged airflow is relatively clean.
[0018] Taking into account that some large particles of solid waste are difficult to be sucked up, the support plate 6 is provided with a plurality of mesh holes distributed in a rectangular array, and the mesh holes penetrate the support plate 6 from top to bottom. A dust hopper 12 is provided below the support plate 6, and a dust collecting box 13 is provided below the dust hopper 12, so that large-volume and large-mass particulate waste in the airflow can freely fall from the mesh holes of the support plate 6 into the dust hopper 12 below under the action of gravity, and then fall into the dust collecting box 13 through the dust hopper 12 for collection. After a certain amount is collected, it can be disassembled for maintenance.
[0019] The use of this equipment can prevent workers from being affected by dusty polluted gases when operating the sandblasting process, thus avoiding harm to their own health and also avoiding pollution to the internal environment of the factory.
[0020] It is worth noting that the technical features such as the sandblasting device, fan, filter cartridge, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and should not be regarded as the inventive point of this utility model patent.
