Abstract

The invention belongs to the technical field of infrared furnace ends, and particularly relates to a durable infrared furnace end in a high-temperature environment, which comprises an infrared ceramic plate and a furnace end shell, wherein the infrared ceramic plate is arranged at the upper end of the furnace end shell, a groove is formed in the upper end of the furnace end shell, the infrared ceramic plate is embedded into the groove, a gas inlet is formed in the middle of the lower end of the furnace end shell, a gas spoiler is arranged in the furnace end shell and is positioned at the upper end of the gas inlet, a plurality of through holes are formed in the gas spoiler, the gas spoiler is fixedly connected with the lower end of the shell through a support, a cooling channel is formed in the furnace end shell, and a water inlet. The cooling water passes through the water inlet and gets into cooling channel, then flows out from the delivery port, cools off the furnace end casing to guarantee that the inside temperature of furnace end casing is unlikely to too high, solved because of the too high gas of furnace end casing internal temperature is at the problem of casting furnace end casing nature or blasting.

Description

Durable infrared furnace end in high-temperature environment

Technical Field

The invention belongs to the technical field of infrared furnace ends, and particularly relates to a durable infrared furnace end in a high-temperature environment.

Background

Porous ceramic plate infrared burners are widely used both industrially and at home. For example, patent application No. 201020113596.3 discloses a novel infrared gas stove furnace end, and this furnace end is provided with automatic ignition device, and the ceramic wafer edge is installed the ignition pole, and the ignition needle easily ignites the ignition pole fast, improves the problem of poor ignition. However, the gas and air mixing effect of the burner is poor, and the burning quality is easily influenced. Of course, the burner head of the prior art is also provided with a corresponding mixing chamber, but the structure is more complicated. Meanwhile, under the condition of long-time combustion of the furnace end, the furnace end shell is overheated and deforms, and gas generated by overheating of the furnace end is natural or exploded in the furnace end.

Disclosure of Invention

Aiming at the technical problem, the invention provides the durable infrared furnace end in the high-temperature environment, and the furnace end can effectively reduce the temperature of the furnace end.

In order to solve the technical problems, the invention adopts the technical scheme that:

the utility model provides a durable infrared furnace end of high temperature environment, includes infrared ceramic plate and furnace end casing, and the infrared ceramic plate sets up the upper end at the furnace end casing, furnace end casing upper end is equipped with the recess, in this recess of infrared ceramic plate embedding, furnace end casing lower extreme middle part is equipped with the gas import, is equipped with the gas spoiler in the furnace end casing, and the gas spoiler is located gas import upper end, is equipped with a plurality of through-hole on the gas spoiler, and the gas spoiler passes through the fixed hookup of support and furnace end casing lower extreme, be equipped with cooling channel in the furnace end casing, be equipped with on the furnace end casing with the water inlet and the delivery port.

The cooling channel is spiral.

The furnace end shell is cylindrical.

And the water inlet and the water outlet are both provided with threads.

The through hole is a circular through hole.

Compared with the prior art, the invention has the following beneficial effects:

the gas inlet is vertically arranged right below the infrared ceramic plate, so that low-pressure mixed gas can be uniformly sprayed out of the infrared ceramic plate and then fully combusted after entering the inner part of the furnace end shell under the blocking effect of the gas spoiler.

At built-in cooling channel of furnace end casing bottom, cooling water passes through the water inlet and gets into cooling channel, then flows out from the delivery port, cools off the furnace end casing to guarantee that the inside temperature of furnace end casing is unlikely to too high, solved because of the too high gas of furnace end casing internal temperature is at the problem of casting furnace end casing nature or blasting.

The gas spoiler is provided with a plurality of through holes, so that part of gas can flow to the infrared ceramic plate above the area blocked by the gas spoiler through the through holes.

Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, a durable infrared furnace end of high temperature environment, including infrared ceramic plate 1 and furnace end casing 2, infrared ceramic plate 1 sets up the upper end at furnace end casing 2, furnace end casing 2 upper end is equipped with recess 20, in this recess 20 of infrared ceramic plate 1 embedding, 2 lower extreme middle parts of furnace end casing are equipped with gas import 3, be equipped with gas spoiler 4 in furnace end casing 2, gas spoiler 4 is located 3 upper ends of gas import, be equipped with a plurality of through-hole on the gas spoiler 4, so that partial gas accessible through-hole flow direction is blockked the infrared ceramic plate 1 of area top by gas spoiler 4. The gas spoiler 4 is fixedly connected with the lower end of the shell through a bracket 5. The low-pressure mixed gas enters the furnace end shell 2 through the gas inlet 3, and is uniformly sprayed out of the infrared ceramic plate 1 and then is combusted under the blocking action of the gas spoiler 4.

A cooling channel 6 is arranged in the furnace end shell 2, and a water inlet 7 and a water outlet 8 which are communicated with the cooling channel 6 are arranged on the furnace end shell 2. The cooling water enters the cooling channel 6 through the water inlet 7 to cool the furnace end shell 2, and then flows out through the water outlet 8.

Further, as shown in fig. 5, the cooling passage 6 is spiral, and thus the contact area can be increased and the cooling effect can be improved.

Further, the burner housing 2 is cylindrical.

Furthermore, the water inlet 7 and the water outlet 8 are both provided with threads, so that the water inlet and the water outlet can be conveniently communicated with a pipeline of a cooling water source.

Further, the through hole is a circular through hole.

The furnace end can adopt an ignition structure recorded in the novel infrared gas furnace end in the background technology to ignite, and can also adopt a common handheld pulse igniter and other devices to ignite.

Although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
