Description

Technical Field

[0001] This invention relates to the technical field of cleaning devices, and in particular to a dual-outlet dry ice cleaning machine. Background Technology

[0002] Currently, the development of dry ice cleaning equipment is particularly rapid. The principle of dry ice cleaning is to spray dry ice particles from the dry ice cleaning machine onto the surface of the object to be cleaned using high-pressure air. The physical reaction of temperature difference causes different substances to detach at different contraction speeds, thereby quickly and thoroughly removing dirt from the surface of the object, achieving a fast, efficient, safe, and energy-saving cleaning effect.

[0003] Existing dry ice cleaning agents generally consist of a base and a rotatable ice-dispensing wheel with several ice-dispensing tanks. The rotation of the ice-dispensing wheel, combined with high-pressure air, blows out dry ice particles, as shown in existing patent "CN103406310A, A Novel Dry Ice Cleaning Device" and the inventor's previous patent "CN103846252B, A Lightweight and Portable Dry Ice Cleaning Machine". These dry ice cleaning machines only have a single dry ice outlet and cannot be designed with multiple outlets operating simultaneously. The main reason for this is that in traditional designs, if the same volume of high-pressure air is input and output through multiple outlets, the airflow rate will be insufficient, affecting the cleaning effect.

[0004] Secondly, the amount of dry ice in the high-pressure air blown out by existing dry ice cleaning agents is often a fixed value, generally determined by the power and specifications at the time of manufacture, and cannot be flexibly adjusted. Users cannot adjust the amount of dry ice according to their needs, which limits its use. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dual-outlet dry ice cleaning machine with optimized and improved structural design, convenient adjustment and operation, and stable and reliable performance.

[0006] To achieve the above objectives, the present invention provides a dual-outlet dry ice cleaning machine, comprising a base and an ice-dispensing wheel, wherein the ice-dispensing wheel is rotatably fitted into a pre-formed rotating cavity in the base; the outer circumferential surface of the ice-dispensing wheel is provided with a plurality of ice-dispensing holes for accommodating dry ice particles; the top of the base is provided with an ice inlet communicating with the rotating cavity; the lower part of the base is provided with a horizontal cavity extending through both sides of the base and communicating with the rotating cavity, the horizontal cavity being divided into an air inlet cavity and two ice outlet cavities, wherein the air inlet cavity communicates with the two ice outlet cavities respectively; the two ice outlet cavities also communicate with the rotating cavity respectively; as the ice-dispensing wheel rotates, the dry ice particles carried by the ice-dispensing holes fall into the two ice outlet cavities, and the dry ice particles are blown out by the high-pressure air input into the air inlet cavity into the two ice outlet cavities respectively.

[0007] Furthermore, the inner wall of the horizontal cavity is integrally formed with a partition, and the partition divides the horizontal cavity into an air inlet chamber and two ice outlet chambers.

[0008] Furthermore, an airflow gap is left between the top of the partition block and the bottom of the ice-dispensing wheel fitted in the rotating cavity. The air inlet cavity is connected to the two ice outlet cavities through the airflow gap. As the ice-dispensing wheel rotates, the dry ice particles carried by the ice-dispensing hole fall into the two ice outlet cavities. The high-pressure air input into the air inlet cavity enters the two ice outlet cavities through the airflow gap and blows the dry ice particles out.

[0009] Furthermore, the base is formed with an exhaust port that communicates with the rotating cavity and extends through one side of the base, wherein the exhaust port is located downstream of the ice outlet cavity along the rotation direction of the ice distribution wheel.

[0010] Furthermore, the ice-dispensing wheel is a hollow cylindrical roller structure, and each ice-dispensing hole extends radially through the ice-dispensing wheel and communicates with the inner cavity of the ice-dispensing wheel; a piston block is slidably fitted into each ice-dispensing hole, and the tail end of each piston block is connected to a coil spring preset in the inner cavity of the ice-dispensing wheel. By rotating and changing the diameter and width of the coil spring, the piston block is slidably adjusted in the ice-dispensing hole, thereby changing the depth of the ice-dispensing hole that can accommodate dry ice particles.

[0011] The present invention adopts the above-mentioned solution, and its beneficial effects are as follows: 1) By directly diverting high-pressure air from the air inlet chamber to the two ice outlet chambers, especially by leaving an airflow gap between the partition block and the bottom of the ice distribution wheel to allow high-pressure air to flow through, sufficient flow velocity is ensured for the high-pressure air blown out of the ice outlet chamber; 2) The piston block is slidably fitted into the ice distribution hole, realizing the adjustment of the dry ice quantity, and the position of the piston block is adjusted accordingly by the expansion or contraction of the coil spring, making the adjustment operation simpler and more flexible; 3) Lower cost, and features high efficiency, excellent cleaning effect, stability and reliability.

[0018] To facilitate understanding of the present invention, a more complete description is given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete.

[0019] Example 1

[0020] See appendix Figure 1-3 As shown in this embodiment, a dual-outlet dry ice cleaning machine includes a base 1 and an ice-dispensing wheel 2. The ice-dispensing wheel 2 is rotatably fitted into a pre-formed rotating cavity in the center of the base 1, and the ice-dispensing wheel 2 and the rotating cavity of the base 1 are tightly matched. Furthermore, the ice-dispensing wheel 2 is equipped with an external power source (preferably a motor, not shown in the figure, which is common knowledge and will not be elaborated here) to drive its rotation. The outer circumference of the ice-dispensing wheel 2 is provided with several ice-dispensing holes 21 for holding dry ice particles. Thus, as the ice-dispensing wheel 2 rotates, the dry ice particles remaining in the ice-dispensing holes 21 rotate accordingly. The top of the base 1 is provided with an ice inlet 11 communicating with the rotating cavity. A hopper (not shown in the figure) containing dry ice particles is connected to the ice inlet 11. Therefore, as the ice-dispensing wheel 2 rotates, each ice-dispensing hole 21 sequentially overlaps and communicates with the ice inlet 11, allowing the dry ice particles in the hopper to fall into the empty ice-dispensing holes 21 through the ice inlet 11.

[0021] Furthermore, the shape of the ice-feeding hole 21 can be designed as square, round, elliptical or polygonal as needed, and its arrangement can also be designed accordingly as needed, without specific limitations here.

[0022] See appendix Figure 3 As shown, in this embodiment, the lower part of the base 1 has a horizontal cavity extending through both sides of the base 1 and communicating with the rotating cavity. The horizontal cavity is located below the rotating cavity. A partition 3 is integrally formed protruding from the inner wall of the horizontal cavity, dividing the horizontal cavity into one air inlet 31 and two ice outlet 32. One port of the horizontal cavity serves as the inlet of the air inlet 31, into which high-pressure air is input by connecting a high-pressure fan (not shown in the figure) to the air inlet 31. The two ice outlet 32 ​​are located on the same side, and the other port of the horizontal cavity is divided into two, serving as the outlets of the two ice outlet 32 ​​respectively. See Appendix Figure 2As shown, an airflow gap 33 is left between the top of the partition block 3 and the bottom of the ice-dispensing wheel 2 embedded in the rotating cavity. The air inlet chamber 31 is connected to the two ice outlet chambers 32 through the airflow gap 33. The diameter of the airflow gap 33 is much smaller than that of the air inlet chamber 31. Because the smaller the air outlet, the higher the flow velocity under the same air volume, the flow velocity of the high-pressure air in the air inlet chamber 31 increases when it flows through the airflow gap 33, thereby inputting high-pressure air with a higher flow velocity into the two ice outlet chambers 32.

[0023] In this embodiment, the two ice outlet chambers 32 are also connected to the rotating chamber. That is, the inlet of the ice outlet chamber 32 is connected to the rotating chamber, and each ice distribution hole 21 is sequentially aligned with and connected to the ice outlet chamber 32 as the ice distribution wheel 2 rotates. The ice outlet chamber 32 is located downstream of the ice inlet 11 along the rotation direction of the ice distribution wheel 2, so that the dry ice particles carried by the ice distribution hole 21 at the ice inlet 11 can fall into the two ice outlet chambers 32 as the ice distribution wheel 2 rotates. Furthermore, the dry ice particles are blown out by the wind force of the high-pressure air input into the ice outlet chamber 32 through the airflow gap 33. Secondly, the extension direction of the airflow gap 33 is tangential to the rotating chamber, so that the high-pressure air will not be directly aimed at the ice distribution wheel 2 and a low-pressure area can be formed in the outer area near the ice distribution hole 21, so that the dry ice particles carried by the ice distribution hole 21 can fall into the ice outlet chamber 32 more quickly.

[0024] In summary, the high-pressure air entering the intake chamber 31 is fed into the two ice outlet chambers 32 through the airflow gap 33, which can generate a higher flow rate. This ensures that, under the same input air volume, the high-pressure air with dry ice particles blown out of the ice outlet chambers 32 still has a sufficient flow rate, effectively avoiding the problem of flow rate reduction caused by flow diversion. This ensures the dry ice cleaning effect. The structural design fundamentally solves the traditional method of replacing the high-pressure blower with a higher-power one to obtain a higher flow rate, which not only ensures the required flow rate but also reduces manufacturing costs.

[0025] Furthermore, the outlet of the ice outlet cavity 32 can be connected to a dry ice sprayer (not shown in the figure), so that the dry ice particles blown out of the ice outlet cavity 32 can be transported to the dry ice sprayer to perform dry ice cleaning on the object to be cleaned.

[0026] Secondly, when the high-pressure air is input into the ice outlet cavity 32, since the ice outlet cavity 32 is connected to the rotating cavity, a portion of the high-pressure air will inevitably enter the ice distribution hole 21 and rotate with the ice distribution wheel 2. If this portion of high-pressure air is not interfered with, it will reach the ice inlet 11 and blow the dry ice particles, affecting the entry of the dry ice particles into the ice distribution hole 21. Based on this, the base 1 is formed with an exhaust port 12 that communicates with the rotating cavity and extends through one side of the base 1. The exhaust port 12 is located downstream of the ice outlet cavity 32 along the rotation direction of the ice distribution wheel 2. That is, each ice distribution hole 21 is sequentially aligned with and communicates with the exhaust port 12 as the ice distribution wheel 2 rotates. This allows the ice distribution hole 21 to rotate to the exhaust port 12 for depressurization and exhaust after the dry ice particles are discharged from the ice outlet cavity 32. Then, it carries the dry ice particles through the ice inlet 11 and is finally transferred to the ice outlet cavity 32. This cycle repeats, greatly reducing the interference of high-pressure air on the ice distribution wheel 2 and the ice inlet 11.

[0027] Example 2:

[0028] In the first embodiment described above, the ice-feeding hole 21 has a fixed depth structure, thus making its load-bearing capacity and cutting amount constant. However, in this second embodiment, a new structural design is added to the ice-feeding wheel 2, making the load-bearing capacity and cutting amount of the ice-feeding hole 21 adjustable. Specifically, see the appendix... Figure 4 and 5 As shown, the ice-dispensing wheel 2 in this embodiment is a hollow cylindrical roller structure. Each ice-dispensing hole 21 extends radially through the ice-dispensing wheel 2 and communicates with the inner cavity of the ice-dispensing wheel 2. Furthermore, a piston block 4 is slidably fitted into each ice-dispensing hole 21. The tail end of each piston block 4 is connected to a coil spring 5 pre-set in the inner cavity of the ice-dispensing wheel 2. Thus, by rotating and changing the diameter of the coil spring 5, the piston block 4 is slidably adjusted within the ice-dispensing hole 21, thereby changing the depth at which the ice-dispensing hole 21 can accommodate dry ice particles. That is, when the coil spring 5 is rotated to expand its diameter, the piston block 4 slides radially outward to decrease the accommodating depth of the ice-dispensing hole 21; conversely, when the coil spring 5 is rotated to contract its diameter, the piston block 4 slides radially outward to increase the accommodating depth of the ice-dispensing hole 21.

[0029] By adjusting the depth of the container as described above, the ice distribution wheel 2 rotates so that the ice distribution hole 21 engages with the ice inlet 11 to cut and break the dry ice particles contained therein, so as to form dry ice particles that meet the particle size requirements and place them in the ice distribution hole 21.

[0030] See appendix Figure 5As shown, in this embodiment, one end of the ice wheel 2 is rotatably equipped with an adjustment part 51 that matches the shape of its inner cavity (the adjustment part 51 and the ice wheel 2 can be connected by screw locking, threaded connection, etc., which is not specifically limited here, and those skilled in the art can choose as needed); the two legs of the coil spring 5 are respectively connected to the adjustment part 51 and the other end of the ice wheel 2. The user can rotate the adjustment part 51 in the forward or reverse direction to realize the coil spring 5 to expand or contract accordingly, and after the adjustment is in place, the adjustment part 51 and the ice wheel 2 are locked and fixed to avoid displacement and other problems during rotation.

[0031] Furthermore, the adjusting part 51, the coil spring 5, and each piston block 4 rotate synchronously with the ice wheel 2.

[0032] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any modifications or variations made by those skilled in the art, without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention. Therefore, all equivalent changes made based on the concept of the present invention without departing from the scope of the present invention should be covered within the protection scope of the present invention.
