Description

Technical Field

[0001] This utility model belongs to the field of sandblasting dust suppression technology, and more specifically, it relates to an environmentally friendly dust suppression device in the sandblasting process. Background Technology

[0002] Sandblasting is a common surface treatment process. It involves using the impact of a high-speed sand jet to clean and roughen the surface of a substrate. In actual sandblasting operations, the high-speed jet inevitably causes a large amount of dust to be airborne. This dust, which is dispersed in the air, not only pollutes the surrounding environment but also threatens the health of the operators. Therefore, in order to effectively address this problem, it is usually necessary to use professional environmental protection dust suppression equipment to properly handle the dust generated during the sandblasting process, thereby reducing dust concentration, improving the working environment, and ensuring production safety.

[0003] According to application number CN202122097303.8, a sandblasting dust suppression environmental protection device includes a horizontally arranged connecting pipe. One end of the connecting pipe is detachably and fixedly connected to a sandblasting gun head. A fixing seat is provided on the connecting pipe near the water spray head, and a threaded through hole is opened on the fixing seat, extending into the connecting pipe. An adjusting bolt is threadedly connected to the threaded through hole. The other end of the connecting pipe is connected to a water spray head. A sandblasting hole communicating with the connecting pipe is opened in the middle of the water spray head. A water storage cavity is opened on the water spray head, which is annular and surrounds the sandblasting hole. An L-shaped water inlet pipe is provided on one side of the water spray head. One end of the water inlet pipe is fixed to the water spray head and communicates with the water storage cavity inside the water spray head. The other end of the water inlet pipe extends towards the connecting pipe. A threaded connector for connection is provided at the inlet of the water inlet pipe. Several water spray holes are evenly arranged around the sandblasting hole at the end of the water spray head away from the connecting pipe, and the water spray holes communicate with the water storage cavity. This utility model has a simple structure and is easy to use.

[0004] Based on the above, the environmental dust suppression equipment used in current sandblasting operations is often in a continuous operating state. After each sandblasting operation, the environmental dust suppression equipment must be manually turned off, making the entire operation process rather cumbersome. Moreover, this mode of continuous operation until manual shutdown is also insufficient in terms of resource utilization, which can easily lead to unnecessary resource waste, making it difficult to achieve efficient resource saving and also hindering the reduction of overall production costs. Utility Model Content

[0010] Furthermore, the sandblasting dust suppression mechanism also includes: a fixing hook and a connecting ring; the fixing hook is fixedly connected to the outer side of the lower end of the sandblasting gun; the connecting ring is hinged to the outer side of the sandblasting switch.

[0011] Furthermore, the replacement mechanism includes: a fixing ring, an annular groove, and a fixing rod; there are two fixing rings, both of which are fixedly connected to the front end face of the sandblasting box; there are two annular grooves, each of which is opened inside the two fixing rings; there are two sets of fixing rods, each of which is fixedly connected to the inside of the two annular grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves dust suppression during sandblasting through the design of a sandblasting dust reduction mechanism. When sandblasting is performed, pressing the sandblasting switch activates the sandblasting gun, which sprays sand material under high-pressure airflow to treat the workpiece. Simultaneously, pressing the sandblasting switch causes the dust reduction switch to slide downwards due to the sliding connection between the connecting groove and the connecting shaft. This sliding action activates the dust reduction nozzle, which then sprays water mist to suppress dust. Notably, the dust reduction nozzle can be opened or closed synchronously with the sandblasting gun, thus improving overall work efficiency, saving resources, and effectively reducing production costs. By changing the mechanism... To facilitate the replacement of sandblasting gloves, the mounting slider is slidably connected to the inner side of the annular groove. Rotating the mounting ring causes the mounting slider to rotate, and the rotating slider engages with the outer side of the fixing rod. Simultaneously, the positioning groove, under the action of a tension spring, engages with the outer side of the fixing rod, thus positioning the mounting ring and completing the installation of the sandblasting gloves. The entire operation is very simple, improving work efficiency while reducing labor intensity. Through the design of this mechanism, dust reduction during sandblasting is achieved, work efficiency is improved, resources are saved, production costs are reduced, and the replacement of sandblasting gloves is facilitated, further reducing labor intensity.
