Technical Field

[0001] This utility model relates to the technical field of dry ice spraying devices, specifically a grinding disc structure for a dry ice spraying device. Background Technology

[0002] Dry ice blasting devices are used to efficiently blast dry ice particles using compressed air to achieve functions such as cleaning and polishing. In current dry ice blasting applications, such as industrial equipment cleaning and precision parts surface treatment, there are increasingly higher requirements for the efficiency and effectiveness of dry ice blasting.

[0003] Existing dry ice blasting devices directly blast dry ice, making it difficult to flexibly adjust the blasting flow rate of dry ice particles according to different operational needs. This results in difficulty achieving ideal results when faced with complex cleaning or treatment tasks, leading to relatively poor work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a grinding disc structure for a dry ice blasting device, which solves the problem that existing devices directly blast dry ice, making it difficult to flexibly adjust the blasting flow rate of dry ice particles according to different operational needs. This results in poor efficiency when facing complex cleaning or treatment tasks.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a grinding disc structure for a dry ice blasting device, comprising a motor, a dry ice blasting mechanism, and a grinding disc mechanism. The dry ice blasting mechanism is fixedly mounted on the outer surface of the motor, and the grinding disc mechanism is fixedly mounted on the output end of the motor. The grinding disc mechanism is disposed inside the dry ice blasting mechanism. The blowing end of the dry ice blasting mechanism is connected to the discharge end of the dry ice blasting mechanism through the storage end of the grinding disc mechanism, and the feeding end of the dry ice blasting mechanism is connected to the storage end of the grinding disc mechanism.

[0007] Furthermore, the dry ice spraying mechanism includes a lower grinding disc fixing plate, which is fixedly installed on the outer surface of the motor. An upper grinding disc fixing plate is provided above the lower grinding disc fixing plate, and a feed port is fixedly installed on the upper surface of the upper grinding disc fixing plate.

[0008] Furthermore, a compressed air inlet pipe is fixedly installed on the upper surface of the upper grinding disc fixing plate.

[0009] Furthermore, the upper grinding disc fixing plate has several sets of first connecting bolts internally threaded together, and the upper grinding disc fixing plate is fixedly installed with the lower grinding disc fixing plate by the first connecting bolts.

[0010] Furthermore, the grinding disc mechanism includes a rotating grinding disc, and the output end of the motor is fixedly mounted with the rotating grinding disc. The rotating grinding disc is disposed between the lower grinding disc fixed plate and the upper grinding disc fixed plate. The interior of the rotating grinding disc is provided with several sets of material grooves, and the material grooves are respectively connected to the feed port.

[0011] Furthermore, the compressed air inlet pipe is connected to the material trough and the material outlet pipe.

[0012] This utility model has the following beneficial effects:

[0013] (1) In this invention, dry ice is added into the material trough on the rotating grinding disc through the feed port. Then, the motor is started to drive the rotating grinding disc to rotate. At the same time, the compressed air source is turned on and the pressure is adjusted to 0.6-0.8MPa so that the compressed air enters the rotating grinding disc through the compressed air inlet pipe. Under the push of the compressed air, the dry ice particles are sprayed out from the discharge pipe at high speed and act on the target surface to achieve cleaning or treatment. During the operation, the grinding disc speed can be adjusted by adjusting the drive motor controller according to the actual situation, and the feed amount of dry ice particles can be adjusted in real time, which can effectively reduce the dry ice loss when cleaning different products.
