Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machine dust removal, in particular to a dust removal structure for a shot blasting machine. Background Technique

[0002] A shot blasting machine uses a high-speed rotating impeller to throw shot at workpieces in the chamber to achieve the purpose of cleaning. It is suitable for the sand cleaning, rust removal, scale removal and surface strengthening of small castings, forgings, stampings, gears, springs and other parts, and is especially suitable for the cleaning and strengthening of parts that are not afraid of collision. Since a large amount of dust is generated during the shot blasting process, if a large amount of dust accumulates in the shot blasting machine for a long time and the shot blasting machine continues to operate, the dust will reattach to the workpiece, causing pollution to the workpiece, and further affecting the gloss and quality of the workpiece surface. Therefore, it is necessary to timely remove the dust in the shot blasting machine, so a dust removal structure for a shot blasting machine is needed.

[0003] The prior art has the following deficiencies: In the prior art, the application number is 201921600774.2, which proposes a dust removal device for a shot blasting machine, relating to the technical field of shot blasting machines. It includes a dust collection pipe and a filter plate. Adjacent two dust collection pipes are communicated through the filter plate, and a plurality of dust collection pipes and filter plates form a filter channel. The two ends of the filter channel are respectively provided with a filter opening and a filter outlet. The utility model can timely remove the dust in the shot blasting machine, has a good dust removal effect, and the filter plate can be disassembled, which is convenient for cleaning or replacement to prevent dust accumulation.

[0004] When the above device is used, a liquid guide port is used to transport cold water for cooling into the filter channel to avoid the situation that the dust temperature in the filter channel is too high and prone to fire, or a precipitant is transported into the channel to facilitate the rapid precipitation of flying dust. A single liquid guide port is used to inject cold water. After the cold water enters the filter channel, it falls in a columnar shape and cannot be evenly distributed in the transport channel, nor can it evenly contact the filter plate. The uniformity of the cold water entering the filter channel is poor, resulting in a poor internal cooling effect. The same is true for the precipitant. At the same time, after the cold water or precipitant passes through the filter channel, it will fall into the collection box with dust and be directly discharged. Water needs to be continuously injected from the liquid guide port, resulting in a large consumption of water resources, causing waste, and the water source with dust is generally directly discharged without an effective treatment method.
