Description

Technical Field

[0001] This utility model relates to the field of compressor processing technology, and in particular to a low-dust shot blasting machine. Background Technology

[0002] The compressor crankshaft is the moving scroll used to mount the compressor. It is a cylindrical part. The eccentric connection at the end causes the moving scroll to move eccentrically when the crankshaft rotates. It works with the stationary scroll to form a continuously changing compression chamber, achieving the compression effect. Due to the large load it bears, the strength requirement is high. When machining the crankshaft, it needs to be strengthened. Shot blasting is one way to strengthen the crankshaft. It can not only strengthen the strength of the crankshaft blank after casting, but also clean and remove rust.

[0003] After shot blasting, existing shot blasting machines contain a large amount of dust in the blasting chamber. Although existing technology has been implemented, a large amount of dust will be transmitted to the outside through the discharge port during discharge, which will affect the outdoor environment, endanger the health of operators, and pose certain safety hazards. At the same time, a large amount of dust will adhere to the surface of the crankshaft, requiring a lot of subsequent cleaning work, which increases the cleaning difficulty and has room for further improvement.

[0016] 2. This utility model is equipped with a side jet seat and a dust removal nozzle. Together with a dust collection seat and a brush seat, it can blow away the dust adhering to the surface of the crankshaft through the high-pressure airflow of the dust removal nozzle when the crankshaft is unloading. The blown-off dust is then removed by the dust collection seat. The hard and soft brushes set below the brush seat can isolate the dust and sweep away the dust on the surface of the crankshaft. Through friction, the crankshaft rolls under the action of the conveyor chain plate, which facilitates the dust cleaning work on other surfaces, reduces cleaning dead corners, and enhances the practicality of the device.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model. The drawings are all in a very simplified form and use non-precise proportions. They are only used to help to explain the embodiments of the present utility model in a convenient and clear way, and should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a low-dust shot blasting machine, including a shot blasting machine body 1 and a discharge platform 2. The shot blasting machine body 1 is a tracked shot blasting machine on the market. The discharge platform 2 is provided at the discharge port of the shot blasting machine body 1. A conveyor chain plate 3 is fixedly connected above the discharge platform 2. A discharge channel 4 is provided on the outside of the discharge platform 2. An air curtain generator 5 is fixedly connected to the upper end of the discharge channel 4 near the shot blasting machine body 1. An air curtain fan 6 is provided on the top of the air curtain generator 5. The side of the air curtain fan 6 near the shot blasting machine body 1 is fixedly connected to the shot blasting machine body 1 through a connecting plate. By providing an air curtain generator 5 and an air curtain fan 6 at the discharge port, an isolation air curtain can be formed. During discharge, the leakage of dust inside the shot blasting chamber is greatly reduced. In addition, the blockage formed by the brushes provided by the discharge channel 4 and the brush seat 13 can effectively isolate the high dust environment inside without affecting the discharge, and reduce the pollution of the outside world by dust leakage.

[0027] Multiple dust collection seats 7 are equidistantly arranged above the discharge channel 4. Each dust collection seat 7 is fixedly connected to a dust collection pipe 8. A connecting pipe 9 is fixedly connected above the multiple dust collection pipes 8. A negative pressure pipe is connected to the top of the connecting pipe 9 and is connected to a bag filter through the negative pressure pipe. Side jet seats 10 are fixedly connected above both sides of the discharge channel 4. Side fans 12 are fixedly connected below the middle of both sides of the discharge channel 4. Multiple dust removal nozzles 11 are fixedly connected through the side wall of the side jet seat 10 near the discharge channel 4. The side fans 12 are fixedly connected to the corresponding multiple dust removal nozzles 11 through the side jet seat 10. The spray direction of the dust removal nozzles 11 is set obliquely downward. When the crankshaft is discharging, the high-pressure airflow of the dust removal nozzles 11 can blow away the dust attached to the surface of the crankshaft. The dust blown off can be removed in time by the dust collection seats 7.

[0028] Inside the discharge channel 4, brush seats 13 are arranged between multiple dust collection seats 7 at the top. Hard brushes 14 are arranged in the middle of the lower part of the multiple brush seats 13. Soft brushes 15 are arranged on both sides of the hard brushes 14 below the multiple brush seats 13. The lowest point of the multiple soft brushes 15 is higher than the side wall of the conveyor chain plate 3. Multiple isolation ribs are fixedly connected to both sides of the conveyor chain plate 3 inside the discharge channel 4 to reduce leakage on both sides of the conveyor chain plate 3. The hard brushes 14 and soft brushes 15 arranged below the brush seats 13 can isolate dust and clean the dust on the crankshaft surface. The friction of the hard brushes 14 causes the crankshaft to roll under the action of the conveyor chain plate 3, which facilitates the dust cleaning work on other surfaces of the crankshaft and reduces cleaning dead corners.

[0029] Working Principle: During operation, this utility model utilizes an air curtain generator 5 and an air curtain fan 6 at the discharge port. Combined with the discharge channel 4 and brush seat 13, the brushes create a barrier, forming an air curtain and filter. This significantly reduces dust leakage from the shot blasting chamber during discharge, effectively isolating the high-dust environment without affecting the discharge process and minimizing dust pollution. Simultaneously, during crankshaft discharge, the high-pressure airflow from the cleaning nozzle 11 blows away dust adhering to the crankshaft surface. The blown-off dust is removed by the dust collection seat 7. The hard brush 14 and soft brush 15 located below the brush seat 13, while isolating dust and cleaning the crankshaft surface, allow the crankshaft to roll under the action of the conveyor chain plate 3 due to the friction of the hard brush 14, facilitating dust cleaning on other surfaces of the crankshaft and reducing cleaning dead zones.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
