Description

Technical Field

[0001] This utility model relates to the technical field of dry ice cleaning machines, specifically to a rotary ice crushing structure. Background Technology

[0002] With the rapid development of the industrial sector, the demand for efficient and environmentally friendly cleaning technologies is becoming increasingly urgent. Traditional cleaning methods often use chemical reagents, which not only pollute the environment but may also damage equipment. Therefore, finding a new and environmentally friendly cleaning technology has become an urgent need for the industrial sector.

[0003] Dry ice cleaning technology has emerged to address this need. It utilizes the energy conversion processes of momentum change, sublimation, and melting of dry ice particles during high-speed spraying to rapidly freeze, solidify, and embrittle dirt, oil, and residual impurities on the surface of the object being cleaned, thus removing them. This method is not only highly efficient but also environmentally friendly, causing no damage to equipment.

[0004] Traditional dry ice cleaning machines in the present technology still frequently experience ice blockage and insufficient ice due to the large differences in the length and size of the ice particles at the ice drop outlet, even with the assistance of mesh filters and vibrators.

[0005] Therefore, it is of great significance to find a rotating ice-breaking structure that can solve the problems existing in the current technology. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a rotary ice crushing structure to solve the problem that in the existing technology of traditional dry ice washing machines, due to the large differences in the length and size of the ice particles, ice blockage and insufficient ice still occur frequently at the ice drop outlet, even with the assistance of mesh filters and vibrators.

The acrylic central tube 1 is mounted on top of the brushless DC motor mounting bracket 11. The stainless steel ice control 10 is mounted on the bottom of the brushless DC motor mounting bracket 11. The motor protective cover 9 is locked to the brushless DC motor mounting bracket 11.

[0035] One end of the clamping shaft 8 is mounted on the main shaft of the DC brushless motor 2 via a rigid coupling 3. The blade 7 and the reserved blade 4 are locked to the other end of the clamping shaft 8. The blade 7 is located above the ice tray 5. An avoidance hole 13 is provided in the middle of the ice tray 5, and the reserved blade 4 is located inside the avoidance hole 13.

[0036] Reference Figure 4The front of the ice tray 5 has three rings of ice-dropping holes 15 and eight elongated slots 14. The three rings of ice-dropping holes 15 and the eight elongated slots 14 are evenly distributed in 360°. The ice tray 5 is made of stainless steel. There is a round hole in the middle for the reserved blade 4 to rotate and assist. The eight evenly distributed elongated slots 14 are air supply channels. The small round hole on the front is the ice-dropping hole. When the ice particles are too large, they will be isolated here and broken down by the blade 7 and the reserved blade 4 before falling. Under the action of negative pressure, they enter the ice outlet tube.

[0037] The brushless DC motor mounting bracket 11 has irregularly shaped holes for ice dropping, and a cable tray is provided on one side of the brushless DC motor mounting bracket 11.

[0038] The stainless steel ice control unit 10 is cone-shaped, and its bottom end is tightly connected to the top end of the ice tray 5 by a silicone ring.

[0039] Reference Figure 5 and 6 The reserved blade 4 is U-shaped, the blade 7 is a rotating half-blade design, the blade 7 is equipped with a symmetrical assisting blade 17 and a square positioning hole 16, the reserved blade 4 is equipped with a U-shaped assisting structure 19 and a directional positioning hole 18, the rotational force is synchronized to prevent icing and assist in ice removal, and the side cutting edge design prevents the blade from slipping.

Silicone gaskets 12 are provided between the top end of the brushless DC motor mounting bracket 11 and the bottom end of the acrylic inlet tube 1, and between the bottom end of the brushless DC motor mounting bracket 11 and the top end of the stainless steel ice control unit 10. By providing silicone gaskets 12, the sealing between the brushless DC motor mounting bracket 11, the acrylic inlet tube 1, and the stainless steel ice control unit 10 is improved.

[0041] In practical use, after the dry ice particles enter the acrylic central tube 1, they fall into the stainless steel ice control chamber 10 through the irregular hole of the brushless DC motor fixing bracket 11, and then collect in the ice tray. The DC brushless motor 2 is started, and the DC brushless motor 2 drives the blade 7 and the reserved blade 4 to rotate through the rigid coupling 3 and the clamping shaft 8. The remaining ice particles are broken up by the rotation of the blade 4 and the reserved blade 4. Under the negative pressure and air replenishment effect of the compressed air, they smoothly enter the ice outlet pipe. Compared with the traditional mesh rotation filter and vibrator, this invention has advantages and can greatly reduce ice blockage and insufficient ice.
