Description

Technical Field

[0001] The utility model relates to dry ice cleaning, in particular to a jet ice crusher. Background Art

[0002] Dry ice cleaning machine is a cleaning system that uses high-pressure air to spray dry ice pellets onto the work surface to be cleaned, and uses the physical reaction of temperature difference to make different substances separate at different shrinkage speeds. When the -78 degrees Celsius dry ice pellets come into contact with the dirt surface, they will produce a brittle explosion phenomenon, causing the dirt to shrink and loosen, and then the dry ice pellets will instantly vaporize and expand 800 times. The product's strong peeling force will quickly and completely remove the dirt from the surface of the object.

[0003] Traditional dry ice cleaning machines use blades to cut dry ice into blocks, and then blow them out with high-pressure gas to form a jet. However, the particles formed by the dry ice after rotary cutting are not uniform and the particle size is relatively large, so the effect of using it directly for cleaning is not good enough.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0024] refer to Figure 1-Figure 4 The present embodiment provides a jet ice crusher for a dry ice cleaning machine, comprising: an ice crusher body; a jet channel for conveying dry ice is provided through the ice crusher body; and at least one grid net 31 is provided on the jet channel along the direction in which the dry ice is loosened. In the present embodiment, there are two grid nets 31, and the projections of the grid openings of the two grid nets 31 along the direction of the dry ice conveying channel do not overlap. In this way, it can be ensured that the dry ice particles passing through the first grid net 31 will not directly pass through the next grid net 31, but will collide and scatter with the next grid net 31 again.

[0025] In order to realize the above-mentioned spray ice crusher structure, the ice crusher body in this embodiment includes a first component 1, a second component 2 and a grid component 3, and the first component 1 and the second component 2 are assembled to form a clamping space for placing the grid component 3. In this way, the grid component 3 is fixed between the first component 1 and the second component 2 in a clamping manner.

[0026] Specifically, the first component 1 includes an installation cavity 11 for connecting with the second component 2, an ice outlet 12, and a contraction portion 13 connected to the installation cavity 11 and the ice outlet 12; the contraction portion 13 has a structure with a gradually decreasing diameter along the direction of dry ice delivery. The function of the contraction portion 13 is to accelerate the dry ice jet to prevent the dry ice jet from colliding with the grid 31 and decelerating and failing to meet the requirements of the dry ice cleaning machine.

[0027] Furthermore, the second component 2 includes a mounting matching cavity 21 for connecting with the mounting cavity 11, an ice inlet 22, and an expansion portion 23 connected between the ice inlet 22 and the mounting matching cavity 21; the expansion portion 23 has a structure with a gradually increasing diameter along the direction of dry ice delivery. The expansion portion 23 is provided to increase the diameter of the clamping space, thereby increasing the area of ​​the grid mesh 31.

[0028] In order to connect the first component 1 and the second component 2 , the inner wall of the installation cavity 11 and the outer wall of the installation matching cavity 21 are provided with internal threads and external threads for matching.

[0029] Furthermore, in order to form the above-mentioned clamping space, the height of the mounting fitting cavity 21 is smaller than the height of the mounting cavity 11, so that after the mounting fitting cavity 21 is connected to the mounting cavity 11, the clamping space is formed between the lower end surface of the mounting fitting cavity 21 and the lower end surface of the mounting cavity 11.

[0030] In order to clamp and fix the grille assembly 3, the lower end surface of the installation cavity 11 extends radially inward to form a circle of supporting surface 111 for supporting the grille assembly 3. The lower end surface of the installation matching cavity 21 extends radially inward to form a circle of abutment surface 211 for clamping the grille assembly 3.

[0031] In this embodiment, the grille assembly 3 is cylindrical, and the grille nets 31 are respectively provided on the upper surface and the lower surface.

[0032] The above-mentioned jet ice crusher is provided with one or more grids 31 on the jet channel of dry ice delivery, so as to collide with the delivered dry ice, further break up the dry ice particles and then pass through the grids 31, so as to achieve uniformity and reduction of the dry ice particles. It can be widely installed on various dry ice cleaning machines to increase the cleaning effect.

[0033] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
