Novel backflow cooling spray gun

Abstract

The utility model provides a novel backflow cooling spray gun, and belongs to the technical field of spray guns. A novel backflow cooling spray gun comprises a spray gun body, a liquid inlet, an atomized air inlet and a spray head are arranged on the spray gun body, and the novel backflow cooling spray gun is characterized in that a cooling shell is arranged on the outer side of the spray gun body, a cooling cavity is formed in the cooling shell, and a water inlet pipe and a water return pipe which are communicated with the cooling cavity are arranged on the outer side of the cooling shell. The spray gun has the advantages that when the spray gun is used, cooling water is introduced into the cooling cavity from the water inlet pipe and exchanges heat with the spray gun body, the cooling water after heat exchange is discharged from the water return pipe, and the water inlet pipe is arranged on the outer side, so that a better cooling effect can be achieved, and the spray gun body is not prone to thermal deformation.

Description

A new type of reflow cooling spray gun Technical Field

[0001] This utility model belongs to the field of spray gun technology and relates to a novel recirculation cooling spray gun. Background Technology

[0002] Two-fluid atomizing spray guns are frequently used in industries such as desulfurization, denitrification, waste liquid combustion, waste liquid calcination, dust removal, and cooling. However, existing two-fluid atomizing spray guns are prone to deformation inside high-temperature furnaces, especially the nozzle, which is easily burned out. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a novel recirculation cooling spray gun, which solves the problem that existing two-flow atomizing spray guns are prone to deformation in high-temperature furnaces, especially the nozzle is prone to burning.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A novel recirculating cooling spray gun includes a spray gun body, which has a liquid inlet, an atomizing air inlet, and a nozzle. The spray gun body is characterized by having a cooling shell on its outer side, a cooling chamber inside the cooling shell, and a water inlet pipe and a water return pipe communicating with the cooling chamber on its outer side.

[0006] Compared with the prior art, the present invention has the following advantages:

[0007] When using the spray gun, cooling water is introduced into the cooling chamber through the inlet pipe to exchange heat with the spray gun body. The cooled water is then discharged through the return pipe. The inlet pipe is located on the outside, which can better play a cooling role and make the spray gun body less prone to thermal deformation. Attached Figure Description

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] As shown in Figure 1,

[0014] A novel recirculating cooling spray gun includes a spray gun body 1, which has a liquid inlet 2, an atomizing air inlet 3, and a nozzle 4. The spray gun body 1 is characterized by having a cooling shell 5 on its outer side, a cooling cavity 6 inside the cooling shell 5, and a water inlet pipe 7 and a water return pipe 8 communicating with the cooling cavity 6 on the outer side of the cooling shell 5.

[0015] In this embodiment, when the spray gun is in use, cooling water is introduced into the cooling chamber 6 through the inlet pipe 7 to exchange heat with the spray gun body 1. The cooled water after heat exchange is discharged through the return pipe 8. The inlet pipe 7 is located on the outside, which can better play a cooling role and make the spray gun body 1 less prone to thermal deformation.

[0016] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0017] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0018] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
