Description

Technical Field

[0001] The utility model belongs to the technical field of combustion gun heads, in particular to a combustion gun head protection device. Background Art

[0002] During the operation of the glass kiln, the glass liquid needs to be heated and melted. This process is inseparable from the combustion gun required for combustion. The combustion gun is located outside the flame space of the kiln and sprays the flame into the kiln through the burner brick with combustion holes.

[0003] When in use, the part where the combustion gun tip contacts the flame will generate high temperature, which may cause the gun tip to burn and even cause a fire accident if used for a long time.

[0004] Therefore, a combustion gun head protection device is needed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a combustion gun head protection device, which effectively solves the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combustion gun head protection device, comprising a protective shell, a side of the protective shell is fixedly connected with an air inlet, the air inlet is used for the entry of compressed air, the inner wall of the protective shell is provided with an air outlet, the air outlet is used for the exhaust of gas, the protective shell is a toroidal structure, the interior of the protective shell is a hollow structure, and the protective shell is welded to the combustion gun frame.

[0007] Furthermore, the air inlet is communicated with the inner side of the protective shell, and the air inlet is connected to an air compression gun.

[0008] Furthermore, the air outlet holes are evenly distributed around the air inlet, and the air outlet holes are connected to the inner cavity of the air inlet.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model fixes the protection device on the combustion gun frame, and the compressed air enters the device through the air inlet and is ejected from the small holes around it, which greatly cools the gun head and avoids the combustion gun head from being burned due to high temperature. At the same time, it can prevent the flame inside the glass kiln from ejecting, greatly reducing the danger of workers replacing the combustion gun. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] Example, by Figure 1-2 The utility model discloses a combustion gun head protection device, including a protection shell 1, which is a toroidal structure. The interior of the protection shell 1 is a hollow structure. The protection shell 1 is welded to the combustion gun frame. An air inlet 2 is fixedly connected to the side of the protection shell 1. The air inlet 2 is connected to the inner side of the protection shell 1. The air inlet 2 is connected to an air compression gun. The air inlet 2 is used for the entry of compressed air. The inner wall of the protection shell 1 is provided with air outlet holes 3. The air outlet holes 3 are used for the discharge of gas. The air outlet holes 3 are evenly distributed around the air inlet 2, and the air outlet holes 3 are connected to the inner cavity of the air inlet 2.

[0017] Working principle: When in use, install the burner gun head on the fixing bracket so that the burner gun head passes through the center position of the protective shell 1, and when in use, place the burner gun head close to the protective shell 1, and connect the air inlet 2 to the air compression gun, so that the compressed air enters the device through the air inlet 2, and then sprays out from the air outlets 3 around it, which has a great cooling effect on the burner gun head.

[0018] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
