Anti-blocking dry ice nozzle

Abstract

The utility model discloses an anti-blocking dry ice sprayer which comprises a spraying pipe, a nozzle arranged on the spraying pipe and communicated with the spraying pipe, and a sleeve arranged on the periphery of the spraying pipe in a sleeved mode, a first circulation channel is arranged in the nozzle and the spraying pipe, and a second circulation channel extending to the periphery of the nozzle is arranged between the sleeve and the spraying pipe. And the end part of the nozzle extends out of the end surface of the sleeve. According to the dry ice cleaning equipment, due to the fact that the end of the nozzle extends out of the end face of the sleeve, when high-pressure air is sprayed out of the second circulation channel, dry ice particles attached to the nozzle can be blown away, the adhesion probability of the dry ice particles is reduced, the phenomenon that the nozzle and the second circulation channel are blocked due to accumulation of the dry ice particles is prevented, and continuous use of the dry ice cleaning equipment is facilitated.

Description

Technical Field

[0001] This utility model relates to the field of dry ice cleaning, and more specifically, to an anti-clogging dry ice nozzle. Background Technology

[0002] Dry ice cleaners are a type of cleaning machine, and dry ice cleaning has seen rapid development globally. The cleaning system uses high-pressure air to propel dry ice particles onto the work surface to be cleaned. The physical reaction caused by the temperature difference causes different substances to detach at different contraction rates. When the -78°C dry ice particles come into contact with the dirt surface, they undergo embrittlement and explosion, causing the dirt to shrink and loosen. The dry ice particles then instantly vaporize and expand 800 times, and the product's powerful peeling force quickly and thoroughly removes dirt from the object's surface, achieving a fast, efficient, safe, and energy-saving cleaning effect.

[0003] In existing dry ice cleaning machines, the liquid carbon dioxide gradually expands as it flows through the nozzle and eventually transforms into dry ice particles after exiting the nozzle. These particles easily adhere to the nozzle opening, causing blockages at the carbon dioxide outlet and air outlet, thus affecting the normal operation of the cleaning machine. Utility Model Content

[0004] This invention addresses the aforementioned deficiencies in the prior art by providing an anti-clogging dry ice nozzle.

[0005] The technical solution adopted by this utility model to solve its technical problem is: to construct an anti-clogging dry ice nozzle, the dry ice nozzle including a nozzle pipe, a nozzle disposed on the nozzle pipe and communicating with the nozzle pipe, and a sleeve sleeved around the nozzle pipe. The nozzle and the nozzle pipe are provided with a first flow channel inside, and a second flow channel extending to the periphery of the nozzle is provided between the sleeve and the nozzle pipe. The end of the nozzle extends out of the end face of the sleeve.

[0006] In the anti-clogging dry ice nozzle of this utility model, the nozzle is provided with a connecting seat for connecting the sleeve.

[0007] In the anti-clogging dry ice nozzle of this utility model, the connecting seat is provided with an air inlet channel that communicates with the second flow channel.

[0008] In the anti-clogging dry ice nozzle of this utility model, the sleeve and the connecting seat are fixedly connected by a plurality of positioning pins. The sleeve is provided with a plurality of first fixing holes through which the positioning pins can pass, and the connecting seat is provided with a plurality of second fixing holes at positions corresponding to the first fixing holes, which are provided for the positioning pins to be inserted.

[0009] In the anti-clogging dry ice nozzle of this utility model, the connecting seat is a cylindrical connecting seat, the sleeve is a cylindrical sleeve, and the sleeve and the connecting seat are detachably fixedly connected by threads.

[0010] In the anti-clogging dry ice nozzle of this utility model, the end face of the sleeve is provided with an air jet port communicating with the second flow channel, and the end of the nozzle extends out from the air jet port.

[0011] In the anti-clogging dry ice nozzle of this utility model, the nozzle is a conical nozzle.

[0012] In the anti-clogging dry ice nozzle of this utility model, the end of the nozzle away from the nozzle is provided with a first external thread or a first internal thread for communicating with an external pipe.

[0013] In the anti-clogging dry ice nozzle of this utility model, the nozzle further includes a mounting base for installing and fixing the nozzle and the sleeve. The mounting base is provided with a second internal thread hole, and the outer wall of the nozzle is provided with a second external thread that can be inserted into the second internal thread hole and screwed into the second internal thread hole.

[0014] In the anti-clogging dry ice nozzle of this utility model, the mounting base is provided with a first connecting hole communicating with the first flow channel and a second connecting hole communicating with the second flow channel.

[0015] The anti-clogging dry ice nozzle of this invention has the following beneficial effects: When using the anti-clogging dry ice nozzle of this invention, liquid carbon dioxide is injected into the nozzle, and high-pressure air is introduced into the second flow channel. The liquid carbon dioxide is sprayed out of the nozzle through the first flow channel. During the flow process, the liquid carbon dioxide gradually expands and is converted into solid dry ice particles at the nozzle. The dry ice particles are accelerated out by the high-pressure air in the second flow channel to achieve the cleaning purpose. In this application, since the nozzle end extends outside the end face of the sleeve, when the high-pressure air is sprayed out from the second flow channel, it can blow away the dry ice particles attached to the nozzle, reducing the probability of dry ice particle adhesion and preventing dry ice particles from accumulating and clogging the nozzle and the second flow channel, thus facilitating the continuous use of the dry ice cleaning equipment.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, in the first embodiment of the anti-clogging dry ice nozzle of this utility model, the dry ice nozzle 10 includes a nozzle 11, a nozzle 12 disposed on the nozzle 11 and communicating with the nozzle 11, and a sleeve 13 sleeved around the nozzle 11. The nozzle 12 and the nozzle 11 are provided with a first flow channel 14, and a second flow channel 15 extending to the periphery of the nozzle 12 is provided between the sleeve 13 and the nozzle 11. The end of the nozzle 12 extends out of the end face of the sleeve 13.

[0023] Understandably, the inner diameter of the sleeve 13 is larger than the outer diameter of the nozzle 11, thereby forming an annular second flow channel 15 between the sleeve 13 and the nozzle 11.

[0024] When using the anti-clogging dry ice nozzle of this invention, liquid carbon dioxide is injected into the nozzle 11, and high-pressure air is simultaneously introduced into the second flow channel 15. The liquid carbon dioxide is ejected from the nozzle 12 through the first flow channel 14. During the flow process, the liquid carbon dioxide gradually expands and transforms into solid dry ice particles at the nozzle 12. The dry ice particles are accelerated out by the high-pressure air in the second flow channel 15, achieving the cleaning purpose. In this application, since the end of the nozzle 12 extends beyond the end face of the sleeve 13, when the high-pressure air is ejected from the second flow channel 15, it can blow away the dry ice particles adhering to the nozzle 12, reducing the probability of dry ice particle adhesion and preventing the accumulation of dry ice particles from clogging the nozzle 12 and the second flow channel 15, thus facilitating the continuous use of the dry ice cleaning equipment.

[0025] In this embodiment, as Figure 1 As shown, the nozzle 11 is provided with a connecting seat 16 for connecting the sleeve 13.

[0026] Specifically, the connector 16 is provided with an air intake channel 17 that communicates with the second flow channel 15.

[0027] Compressed air first enters the intake passage 17, and then enters the second flow passage 15 from the intake passage 17.

[0028] In this embodiment, as Figure 1As shown, the sleeve 13 and the connecting seat 16 are fixedly connected by a plurality of positioning pins 18. The sleeve 13 is provided with a plurality of first fixing holes 19 through which the positioning pins 18 can pass. The connecting seat 16 is provided with a plurality of second fixing holes 20 at positions corresponding to the first fixing holes 19, through which the positioning pins 18 can be inserted.

[0029] When fixing the sleeve 13, align the first fixing hole 19 on the sleeve 13 and the second fixing hole 20 on the connecting seat 16, and then insert the positioning pin 18 into the first fixing hole 19 and the second fixing hole 20 to fix the sleeve 13.

[0030] In other embodiments, the connector 16 is a cylindrical connector 16, the sleeve 13 is a cylindrical sleeve 13, and the sleeve 13 and the connector 16 are detachably fixedly connected by threads.

[0031] When installing the sleeve 13, the sleeve 13 can be rotated and screwed onto the connecting seat 16 to achieve fixed installation of the sleeve 13.

[0032] Specifically, such as Figure 2 As shown, the end face of the sleeve 13 is provided with an air jet 21 that communicates with the second flow channel 15, and the end of the nozzle 12 extends out from the air jet 21.

[0033] Understandably, the end of the nozzle 12 extends from the center of the air outlet 21, so that the high-pressure air ejected from the air outlet 21 can surround the outer periphery of the nozzle 12. The annular air outlet 21 can blow away dry ice particles that adhere to any part of the outer periphery of the nozzle 12.

[0034] Preferably, the nozzle 12 is a conical nozzle 12. Correspondingly, the second flow channel 15 is a corresponding conical orifice.

[0035] Furthermore, the nozzle 11 has a first external thread or a first internal thread 22 at one end away from the nozzle 12 for communicating with an external pipe.

[0036] In this embodiment, as Figure 3 , 4 As shown, the nozzle 10 also includes a mounting base 25 for mounting and fixing the nozzle 11 and the sleeve 13. The mounting base 25 is provided with a second internal thread hole 24, and the outer wall of the nozzle 11 is provided with a second external thread 23 that can be inserted into the second internal thread hole 24 and screwed into the second internal thread hole 24.

[0037] When installing the nozzle 11, the nozzle 11 can be aligned with the second internal thread hole 24 and inserted, and then the nozzle 11 can be rotated until the second external thread 23 is screwed into the second internal thread 24, thus achieving the overall fixed installation of the nozzle 10.

[0038] Furthermore, the mounting base 25 is provided with a first connecting hole 26 communicating with the first flow channel 14 and a second connecting hole 27 communicating with the second flow channel 15. Liquid carbon dioxide enters the first flow channel 14 through the first connecting hole 26, while high-pressure air enters the second flow channel 15 through the second connecting hole 27.

[0039] Furthermore, in this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
